Full textAbstract:
As individuals the ideal learning scenario would be a learning environment tailored just for how we like to learn, personalised to our requirements. This has previously been almost inconceivable given the complexities of learning, the constraints within the environments in which we teach, and the need for global repositories of knowledge to facilitate this process. Whilst it is still not necessarily achievable in its full sense this research project represents a path towards this ideal. In this thesis, findings from research into the development of a model (the Adaptive Intelligent Personalised Learning (AIPL)), the creation of a prototype implementation of a system designed around this model (the AIPL environment) and the construction of a suite of intelligent algorithms (Personalised Adaptive Filtering System (PAFS)) for personalised learning are presented and evaluated. A mixed methods approach is used in the evaluation of the AIPL environment. The AIPL model is built on the premise of an ideal system being one which does not just consider the individual but also considers groupings of likeminded individuals and their power to influence learner choice. The results show that: (1) There is a positive correlation for using group-learning-paradigms. (2) Using personalisation as a learning aid can help to facilitate individual learning and encourage learning on-line. (3) Using learning styles as a way of identifying and categorising the individuals can improve their on-line learning experience. (4) Using Adaptive Information Retrieval techniques linked to group-learning-paradigms can reduce and improve the problem of mis-matching. A number of approaches for further work to extend and expand upon the work presented are highlighted at the end of the Thesis.

Full textAbstract:
The aim of this diploma thesis work was to create new applications for intelligent and adaptive lighting in retail environment. Lighting is an important factor in generating atmosphere in retail space and it has been shown to affect customer behavior. Combining intelligent technology with lighting design enables new applications for creating an environment that senses the presence of the user. It can be employed to adapt the lighting to inform and guide the customer by creating visual focal points. Alternatively, the level of illumination can be adapted to the different requirements of the use, e.g. the presence of customers or employees. The methods used in this study were scenario working and implementation. Four major themes were defined to approach the subject: 1. Navigation and guidance, 2. Product display and browsing, 3. Pleasure and entertainment, and 4. Natural light and simulated natural light. The themes were studied in a form of short stories written from point of view of both customer or designer, and the chosen applications were further studied and implemented in a hypermarket environment. The implementations were presented as two case studies: Aisles and shelves and Landmarks and dynamic display lighting. The first case study describes lighting of the grocery store shelves. The following things were considered in the design: the noticeability of the ends of the shelves that have high value in product placement, the direction of the light, and the adaptability of lighting to the customer’s presence. An approaching customer triggers the sequential brightening of luminaires in between the shelves. The second case study considered focal points in retail environment and dynamic display lighting. In the lighting design, the landmarks, or focal points, are areas of interest that appeal and guide the customer. This is achieved in the design by using higher intensity of light compared to the surrounding environment or more colorful lighting. By displaying products under dynamic lighting, the changes in light intensity attract customer’s attention and increase the noticeability of products illuminated in this fashion. Lighting is a versatile tool that can be easily used to change the appearance and atmosphere of retail environment from one season to another, keeping the store interesting and appealing to the customer. With current technology, these changes can be applied in an intelligent and adaptive manner: lighting can interact with customers and employees, and it can be made easily controllable for designers and visualists. The discovered applications can be applied to several types of retail environments, and depending on the application, also to other types of architectural spaces, for example museums and exhibition spacesDiplomityöni tavoitteena on kehittää uudenlaisia älykkäitä ja mukautuvia valaistusratkaisuita myymälätiloihin. Valaistus on tärkeä myymälätilojen ilmapiirille ja sen on osoitettu vaikuttavan asiakkaan käyttäytymiseen. Kun valaistussuunnittelu soveltaa älykästä teknologiaa, ihmisen läsnäoloa aistivaa ympäristöä voidaan toteuttaa uusilla tavoilla. Vaihtoehtoisesti, valaistuksen tasoa voidaan säätää tilan eri käyttötarkoituksen mukaan, esimerkiksi asiakkaan tai henkilökunnan tarpeisiin. Diplomityöni on tehty käyttäen menetelminä skenaariotyöskentelyä ja suunnittelua. Käsittelin aihetta neljän pääteeman mukaisesti: 1. Liikkuminen ja ohjaaminen, 2. Esillepano ja löytäminen, 3. Viihtyminen ja viihdyttäminen sekä 4. Luonnonvalo ja luonnonvalon simulointi. Kirjoitin teemoista lyhyitä tarinoita asiakkaan ja suunnittelijan näkökulmista. Tutkin valittuja käyttökohteita tarkemmin ja sovelsin suunnitelmia hypermarket-ympäristöön. Esittelen suunnitelmaosuuden kahden esimerkin kautta: Hyllyt ja käytävät sekä Kiintopisteet ja dynaaminen tuotevalaistus. Ensimmäinen esimerkki käsittelee ruokaosaston hyllyjen valaistusta. Suunnittelussa olen kiinnittänyt huomiota hyllyjen päätyyn sijoitettujen tuotteiden näkyvyyteen, valon suuntaukseen ja valaistuksen mukautumiseen asiakkaan läsnäoloon. Lähestyvä asiakas aktivoi hyllyjen väliin sijoitettujen valaisinten vaiheittaisen kirkastumisen. Toisessa esimerkissä käsittelen kiintopisteitä myymälätilassa ja dynaamista tuotteiden valaistusta. Olen käyttänyt kiintopisteiden valaisussa ympäristöä suurempaa valon intensiteettiä tai värillistä valoa houkuttelemaan ja ohjaamaan asiakasta. Tuotteisiin kohdistuvan valon määrän muutokset herättävät asiakkaan mielenkiinnon lisäten valaistujen tuotteiden näkyvyyttä. Valaistus on monipuolinen työkalu, jolla voi helposti muuttaa myymälätilan ilmettä ja tunnelmaa ja siten pitää yllä asiakkaan mielenkiintoa sesongista toiseen. Älykkään nykyteknologian keinoin voidaan toteuttaa mukautuva, asiakkaan ja työntekijän kanssa vuorovaikuttava valaistus, joka on helposti suunnittelijan ja visualistin toteutettavissa ja ohjattavissa. Työssä käsiteltyjä uusia käyttötarkoituksia voi soveltaa myös muihin ympäristöihin, kuten museoihin ja näyttelytiloihin

Surgical procedures conducted without proper guidance and dynamic feedback mechanism could lead to unintended consequences. In-vivo diagnostics and imaging (the Gastro-Intestinal tract) has shown to be inconvenient for the patients using traditional endoscopic instruments and often these conventional methods are limited in terms of their access to various organs (e.g. small intestines). Embedding sensors inside the living body is complex and further the communication with the implanted sensors is challenging using the current RF technology. Additionally, continuous replacement and/or batteries recharging for wireless sensors networks both in-vivo and ex-vivo adds towards the complexity. Advances in diagnostics and prognostics techniques require development at multiple levels through systems approach, guided by the futuristic intelligent decision making environment that reduces the human interference. The demands are not only at the component level, but also at the connectivity of the components such that secure, sustainable, self-reliant, and intelligent environment can be realized. This thesis provides important breakthroughs required to achieve the vision of intelligent healthcare environment. The research contributions of this thesis provide foundation for developing a new architecture for continuous medical diagnostic and monitoring. The chapters in this thesis cover four fundamental technologies covering the in-vivo imaging, ex-vivo imaging, energy for sensors, and acoustic communication. These technologies are: locomotion mechanism for wireless capsule endoscope (WCE), multifunctional image guided surgical (MIGS) platform, shape memory alloy (SMA) thermal energy harvester and thermo-acoustic sonar using carbon nanotube (CNT) sheets.
First, two types of locomotion mechanisms were developed, the first one inspired by millipede legged type mechanism and the second one based on the traveling waves that were induced onto the walls of the WCEs through vibration. Both mechanisms utilize piezoelectric actuators and couple their dynamics and actuation capability in order to achieve propulsion. This controlled locomotion will provide WCE advantage in terms of conducting localized diagnostics. Next, in order to conduct ex-vivo surgical procedures using the OCT such as removing the unwanted tissue and tumors short distance beneath the skin, MIGS platform was developed. The MIGS platform is composed of three key elements: optical coherence tomography (OCT) probe, laser scalpel and high precision miniature scanning and positioning stage. The focus in this dissertation was on design and development of the programmable scanning and positioning stage. The combination of in-vivo tool such as WCE and ex-vivo tool such as MIGS will provide opportunity to conduct many non-invasive procedures which will save time and cost. In order to power the feedback sensors that assist in remote operation of surgical procedures and automation of the diagnostic algorithms, an energy harvester technology based on the SMA thermal engine was designed, fabricated, and characterized. A mechano-thermal model for the overall SMA engine was developed and experimentally validated. Finally, the thermo-acoustic sound generation mechanism using CNT sheets was investigated with the goal of developing techniques for acoustic localization of WCE and customized sound generation devices. CNT thermo-acoustic projectors were modeled and experimentally characterized to quantify the dynamics of the system under varying drive conditions.
The overall vision of this thesis is to lay down the foundation for intelligent healthcare environment that provides the ability to conduct automated diagnostics, prognostics, and non-invasive surgical procedures. In accomplishing this vision, the thesis has addressed several key fundamental aspects of various technologies that will be required for implementing the automation algorithms.Ph. D.

Akhlaghinia, M. J. "Occupancy monitoring and prediction in ambient intelligent environment." Thesis, Nottingham Trent University, 2010. http://irep.ntu.ac.uk/id/eprint/281/.
Full textAbstract:
Occupancy monitoring and prediction as an influential factor in the extraction of occupants' behavioural patterns for the realisation of ambient intelligent environments is addressed in this research. The proposed occupancy monitoring technique uses occupancy detection sensors with unobtrusive features to monitor occupancy in the environment. Initially the occupancy detection is conducted for a purely single-occupant environment. Then, it is extended to the multipleoccupant environment and associated problems are investigated. Along with the occupancy monitoring, it is aimed to supply prediction techniques with a suitable occupancy signal as the input which can enhance efforts in developing ambient intelligent environments. By predicting the occupancy pattern of monitored occupants, safety, security, the convenience of occupants, and energy saving can be improved. Elderly care and supporting people with health problems like dementia and Alzheimer disease are amongst the applications of such an environment. In the research, environments are considered in different scenarios based on the complexity of the problem including single-occupant and multiple-occupant scenarios. Using simple sensory devices instead of visual equipment without any impact on privacy and her/his normal daily activity, an occupant is monitored in a living or working environment in the single-occupant scenario. ZigBee wireless communication technology is used to collect signals from sensory devices such as motion detection sensors and door contact sensors. All these technologies together including sensors, wireless communication, and tagging are integrated as a wireless sensory agent. The occupancy data is then collected from different areas in the monitored environment by installing a wireless sensory agent in each area. In a multiple-occupant scenario, monitored occupants are tagged to support sensory signals in distinguishing them from nonmonitored occupants or visitors. Upon enabling the wireless sensory agents to measure the radio signal strength of received data from tags associated with occupants, wireless localising sensory agents are formed and used for occupancy data collection in the multiple-occupant scenario. After the data collection, suitable occupancy time-series are generated from the collected raw data by applying analysis and suitable occupancy signal representation methods, which make it possible to apply time-series predictors for the prediction of reshaped occupancy signal. In addition, an occupancy signal generator is proposed and implemented to generate sufficient occupancy signal data for choosing the best amongst the prediction techniques. After converting the occupancy of different areas in an environment to an occupancy timeseries, the occupancy prediction problem is solved by time-series analysis and prediction techniques for the single-occupant scenario. The proposed technique has made it possible to predict the occupancy signal for 530 seconds in a real environment and up to 900 seconds for a virtual environment. The occupancy signal generator created based on the proposed statistical model is proved to be able to generate different occupancy signals for different occupant profiles incorporating different environmental layouts. This can give a good understanding of the occupancy pattern in indoor spaces and the effect of the uncertainty factors in the occupancy time-series. In the multiple-occupant scenario, the tagging technology integrated with data acquisition system has made it possible to distinguish monitored occupants and separate their occupancy signals. Separated signals can then be treated as individual time-series for prediction. All the proposed techniques and models are tested and validated by real occupancy data collected from different environments.

Full textAbstract:
Signal control systems have experienced tremendous development both in hardware and in control strategies in the past 50 years since the advent of the first electronic traffic signal control device. The state-of-art real-time signal control strategies rely heavily on infrastructure-based sensors, including in-pavement or video based loop detectors for data collection. With the emergence of connected vehicle technology, mobility applications utilizing vehicle to infrastructure (V2I) communications enable the intersection to acquire a much more complete picture of the nearby vehicle states. Based on this new source of data, traffic controllers should be able to make "smarter" decisions. This dissertation investigates the traffic signal control strategies in a connected vehicle environment considering mobility as well as safety. A system architecture for connected vehicle based signal control applications under both a simulation environment and in the real world has been developed. The proposed architecture can be applied to applications such as adaptive signal control, signal priority including transit signal priority (TSP), freight signal priority (FSP), emergency vehicle preemption, and integration of adaptive signal control and signal priority. Within the framework, the trajectory awareness of connected vehicles component processes and stores the connected vehicle data from Basic Safety Message (BSM). A lane level intersection map that represents the geometric structure was developed. Combined with the map and vehicle information from BSMs, the connected vehicles can be located on the map. Some important questions specific to connected vehicle are addressed in this component. A geo-fencing area makes sure the roadside equipment (RSE) receives the BSM from only vehicles on the roadway and within the Dedicated Short-range Communications (DSRC) range. A mechanism to maintain anonymity of vehicle trajectories to ensure privacy is also developed. Vehicle data from the trajectory awareness of connected vehicles component can be used as the input to a real-time phase allocation algorithm that considers the mobility aspect of the intersection operations. The phase allocation algorithm applies a two-level optimization scheme based on the dual ring controller in which phase sequence and duration are optimized simultaneously. Two objective functions are considered: minimization of total vehicle delay and minimization of queue length. Due to the low penetration rate of the connected vehicles, an algorithm that estimates the states of unequipped vehicles based on connected vehicle data is developed to construct a complete arrival table for the phase allocation algorithm. A real-world intersection is modeled in VISSIM to validate the algorithms. Dangerous driving behaviors may occur if a vehicle is trapped in the dilemma zone which represents one safety aspect of signalized intersection operation. An analytical model for estimating the number of vehicles in dilemma zone (NVDZ) is developed on the basis of signal timing, arterial geometry, traffic demand, and driving characteristics. The analytical model of NVDZ calculation is integrated into the signal optimization to perform dilemma zone protection. Delay and NVDZ are formulated as a multi-objective optimization problem addressing efficiency and safety together. Examples show that delay and NVDZ are competing objectives and cannot be optimized simultaneously. An economic model is applied to find the minimum combined cost of the two objectives using a monetized objective function. In the connected vehicle environment, the NVDZ can be calculated from connected vehicle data and dilemma zone protection is integrated into the phase allocation algorithm. Due to the complex nature of traffic control systems, it is desirable to utilize traffic simulation in order to test and evaluate the effectiveness and safety of new models before implementing them in the field. Therefore, developing such a simulation platform is very important. This dissertation proposes a simulation environment that can be applied to different connected vehicle related signal control applications in VISSIM. Both hardware-in-the-loop (HIL) and software-in-the-loop (SIL) simulation are used. The simulation environment tries to mimic the real world complexity and follows the Society of Automotive Engineers (SAE) J2735 standard DSRC messaging so that models and algorithms tested in the simulation can be directly applied in the field with minimal modification. Comprehensive testing and evaluation of the proposed models are conducted in two simulation networks and one field intersection. Traffic signal priority is an operational strategy to apply special signal timings to reduce the delay of certain types of vehicles. The common way of serving signal priority is based on the "first come first serve" rule which may not be optimal in terms of total priority delay. A priority system that can serve multiple requests with different priority levels should perform better than the current method. Traditionally, coordination is treated in a different framework from signal priority. However, the objectives of coordination and signal priority are similar. In this dissertation, adaptive signal control, signal priority and coordination are integrated into a unified framework. The signal priority algorithm generates a feasible set of optimal signal schedules that minimize the priority delay. The phase allocation algorithm considers the set as additional constraints and tries to minimize the total regular vehicle delay within the set. Different test scenarios including coordination request, priority vehicle request and combination of coordination and priority requests are developed and tested.

Bientôt, les robots ne travailleront plus de manière isolée mais avec nous. Ils entrent peu à peu dans notre vie de tous les jours pour coopérer, assister, aider, servir, apprendre, enseigner ou même jouer avec l'homme. Dans ce contexte, nous considérons que ce ne doit pas être à l'homme de s'adapter au robot. Au contraire, le robot doit être capable d'intégrer, dans ses stratégies de planification et de décision, différents facteurs d'effort et de confort et de prendre en compte les préférences et désirs de l'homme ainsi que les normes sociales de son environnement. Tout en respectant les principes de sécurité réglementaire, le robot doit se comporter, naviguer, manipuler, communiquer et apprendre d'une manière qui soit pertinente, acceptée et compréhensible par l'homme. Cette thèse explore et définit les ingrédients clés nécessaires au robot pour développer une telle intelligence socio-cognitive. Elle définit également un cadre pour l'interaction homme-robot permettant de s'attaquer à ces challenges dans le but de rendre le robot socialement intelligentRobots will no longer be working isolated from us. They are entering into our day-to-day life to cooperate, assist, help, serve, learn, teach and play with us. In this context, it is important that because of the presence of robots, the human should not be on compromising side. To achieve this, beyond the basic safety requirements, robots should take into account various factors ranging from human’s effort, comfort, preferences, desire, to social norms, in their various planning and decision making strategies. They should behave, navigate, manipulate, interact and learn in a way, which is expected, accepted, and understandable by us, the human. This thesis begins by exploring and identifying the basic yet key ingredients of such socio-cognitive intelligence. Then we develop generic frameworks and concepts from HRI perspective to address these additional challenges, and to elevate the robots capabilities towards being socially intelligent

Full textAbstract:
This thesis describes research on methods for Ubiquitous/Pervasive Computing to better
suit users in an Intelligent Environment. The approach is to create and equip a computing
environment, such as our Active Office, with technologies that can identify user needs
and meet these need in a timely, efficient and unobtrusive manner.¶
The critical issues in the Intelligent Environment are how to enable transparent,
distributed computing to allow continued operation across changing circumstances and
how to exploit the changing environment so that it is aware of the context of user
location, the collection of nearby people and objects, accessible devices and changes to
those objects over time.¶
Since the Intelligent Environment is an environment with rapid and rich computing
processing, the distributed context processing architecture (DiCPA) was developed to
manage and respond to rapidly changing aggregation of sensor data. This architecture is a
scalable distributed context processing architecture that provides: 1. continued operation
across changing circumstances for users, 2. the collection of nearby people and objects, 3.
accessible devices and 4. the changes to those objects over time in the environment. The
DiCPA approach focuses on how the Intelligent Environment provides context
information for user location, user mobility and the user activity model. Users are
assumed mobile within the Intelligent Environment and can rapidly change their access to
relevant information and the availability of communications and computational resources.¶
Context-Aware Computing is a new approach in software engineering for Intelligent
Environment. It is an approach in the design and construction of a context-aware
application that exploits rapid changes in access to relevant information and the
availability of communication and computing resources in the mobile computing
environment. The goal of Context-Aware Computing is to make user interaction with the
computer easier in the smart environment where technology is spread throughout
(pervasive), computers are everywhere at the same time (ubiquitous) and technology is
embedded (ambient) in the environment. Context-aware applications need not be
difficult, tedious or require the acquisition of new skills on the part of the user. They
should be safe, easy, simple to use and should enable new functionality without the need
to learn new technology. They should provide relevant information and a simple way for
a user to manage.¶
The Intelligent Environment requires a context-aware application to improve its
efficiency and to increase productivity and enjoyment for the user. The context awareness
mechanism has four fundamental cores i.e. identity (who), activity (what), location
(where) and timestamp (when). Based on DiCPA architecture, the model of user location
(where), user mobility (where), user activity (what) and Intelligent Environment response
(what) were developed. Prototypes were also developed to proof the Context-Aware
Computing concept in the Intelligent Environment.¶
An Intelligent Environment uses the multi-disciplinary area of Context-Aware
Computing, which combines technology, computer systems, models and reasoning, social
aspects, and user support. A good quality project for Context-Aware Computing
requires core content and provides iterative evaluation processes, which has two types of
iteration: design and product iteration of the evaluation. The aim of the development of
an evaluation program in Context-Aware Computing is to determine what to test, how to
test and the appropriate metrics to use. This work presents the metrics for a good quality
project in the Context-Aware Computing area, which is followed by the evaluation of the
prototypes of this work.

Li, Na. "Intelligent transmitter/receiver to locate infrared user in environment." Thesis, University of Warwick, 2009. http://wrap.warwick.ac.uk/2278/.
Full textAbstract:
Infrared (IR) handover is the procedure providing the change from one transmitter to another in an indoor environment. Since each transmitter covers a predefined small geographical area and handles the need of the infrared user for data transfer in that area. The active infrared user needs to change its transmitting point of connection to a wired backbone network while it is moving across the coverage boundaries of the multiple transmitters to which it is connected. For improving overall network performance, the active infrared user must be connected to the most suitable transmitter while accessing the data transfer provided by the fixed network. Therefore, a new smart active IR transceiver system has been described which accommodates handover for mobile infrared communications. A system has been designed and implemented using one receiver and three transmitters within an indoor environment. The system performance has been evaluated, and issues such as position, orientation, and radiation pattern of the signal sources and receiver have been tackled. The desired signal power for the proposed handover evaluation method is given by the average photocurrent that corresponds to the average optical power incident on the photodiode. However, the main limitation to the bandwidth of the IR front-end is the photodiode capacitance, so that the level of received header signal at the sampling point is modified by the front-end transfer function, which may lead to a wrong decision based on the IR channel quality estimation. Thus, in order to reduce the effect of noise and bandwidth aspects, a raised-cosine-output pulse shape to represent the digital baseband signal is the proposed method for optimizing the estimation of the average transmitter power. That is an active IR receiver can automatically make comparison and then selection of a transmitter which has the transmission quality of the greatest preference based on the recognized header pulse from the received and combined header signals, and finally it could only recover one 16-PPM modulated data block in the form of a time-division-multiplexed stream having the greatest quality.

Today there are many IT-systems holding information about different things. The information can for example be anything from news feeds to complex environment systems. By making these system collaborate with each other new oppurtunities and functionality can be established. However, since most of the systems are developed individually, there are different ways to communicate with each system. Therefore, The IT-agency Gaia has started a collaboration with the real estate company Klövern AB. The intention was to develop a plat- form for functional- and informational distribution focusing on commercial real estates. The platform was supposed to be available for Klöverns tenants and be used in public environments providing access to intelligent environment systems, processes in facility management and interactive information channels. This report describes the user study, the idea development and the implementation of two Windows 8 Metro application prototypes communicating through this platform. The two prototypes was directed towards the Cnema and Gaia which are both tenants of Klövern. Furthermore, both the applications was written in C# and uses ASP.Net library Signalr for real-time communication.

Full textAbstract:
The problem of providing help for complex application interfaces has been a source of interest for a number of researcher efforts. As the computational power of computers increases, typical applications not only increase in functionality but also in the degree of interaction with the computational environment in which they reside. There are powerful software tools available today used for both specialized and non-specialized tasks that are often used by novice users who attempt tasks without significant training or knowledge of the application?s interface. These kinds of applications are diverse and complicated in the variety of functionality they provide, often interacting with other applications on the user?s system. With current platforms (Windows, Macintosh, Linux etc) providing extensive multi-tasking facilities, interaction with these applications is sometimes affected by the context of the environment itself (e.g., application windows being minimized, maximized or obscured by those of other applications). The interdependencies between applications and their environments increase the difficulty of providing effective context-sensitive help when building an application?s help documentation. The purpose of this research is to create an Intelligent Help System, which incorporates these interactions and affecting factors when providing help. The SmartAidè system, which was developed as part of this effort, works on the premise that the user has a goal when interacting with the application. This document will provide a detailed overview of the architecture of the system along with the underlying design decisions. The system was then evaluated against traditional application help documentation to test its effectiveness. The results and analysis of this evaluation have been enumerated.

Full textAbstract:
Le développement de véhicules autonomes capables de se déplacer sur les routes urbaines peuvent fournir des avantages importants en matière de réduction des accidents, en augmentant le confort et aussi, permettant des réductions de coûts. Les véhicules Intelligents par exemple fondent souvent leurs décisions sur les observations obtenues à partir de différents capteurs tels que les LIDAR, les GPS et les Caméras. En fait, les capteurs de la caméra ont reçu grande attention en raison du fait de qu’ils ne sont pas cher, facile à utiliser et fournissent des données avec de riches informations. Les environnements urbains représentent des scénarios intéressant mais aussi très difficile dans ce contexte, où le tracé de la route peut être très complexe,la présence d’objets tels que des arbres, des vélos, des voitures peuvent générer des observations partielles et aussi ces observations sont souvent bruyants ou même manquant en raison de occlusions complètes. Donc, le processus de perception par nature doit être capable de traiter des incertitudes dans la connaissance du monde autour de la voiture. Tandis que la navigation routière et la conduite autonome en utilisant une connaissance préalable de l’environnement ont démontré avec succès, la compréhension et la navigation des scénarios généraux du environnement urbain avec peu de connaissances reste un problème non résolu. Dans cette thèse, on analyse ce problème de perception pour la conduite dans les milieux urbains basée sur la connaissance de l’environnement pour aussi prendre des décisions dans la navigation autonome. Il est conçu un système de perception robotique, qui permettre aux voitures de se conduire sur les routes, sans la nécessité d’adapter l’infrastructure, sans exiger l’apprentissage précédente de l’environnement, et en tenant en compte la présence d’objets dynamiques tels que les voitures.On propose un nouveau procédé basé sur l’apprentissage par la machine pour extraire le contexte sémantique en utilisant une paire d’images stéréo qui est fusionnée dans une grille d’occupation évidentielle pour modéliser les incertitudes d’un environnement urbain inconnu,en utilisant la théorie de Dempster-Shafer. Pour prendre des décisions dans la planification des chemins, il est appliqué l’approche de tentacule virtuel pour générer les possibles chemins à partir du centre de référence de la voiture et sur cette base, deux nouvelles stratégies sont proposées. Première, une nouvelle stratégie pour sélectionner le chemin correct pour mieux éviter les obstacles et de suivre la tâche locale dans le contexte de la navigation hybride, et seconde, un nouveau contrôle en boucle fermée basé sur l’odométrie visuelle et tentacule virtuel est modélisée pour l’exécution du suivi de chemin. Finalement, un système complet automobile intégrant les modules de perception, de planification et de contrôle sont mis en place et validé expérimentalement dans des situations réelles en utilisant une voiture autonome expérimentale, où les résultats montrent que l’approche développée effectue avec succès une navigation locale fiable basée sur des capteurs de la caméraThe development of autonomous vehicles capable of getting around on urban roads can provide important benefits in reducing accidents, in increasing life comfort and also in providing cost savings. Intelligent vehicles for example often base their decisions on observations obtained from various sensors such as LIDAR, GPS and Cameras. Actually, camera sensors have been receiving large attention due to they are cheap, easy to employ and provide rich data information. Inner-city environments represent an interesting but also very challenging scenario in this context,where the road layout may be very complex, the presence of objects such as trees, bicycles,cars might generate partial observations and also these observations are often noisy or even missing due to heavy occlusions. Thus, perception process by nature needs to be able to dea lwith uncertainties in the knowledge of the world around the car. While highway navigation and autonomous driving using a prior knowledge of the environment have been demonstrating successfully,understanding and navigating general inner-city scenarios with little prior knowledge remains an unsolved problem. In this thesis, this perception problem is analyzed for driving in the inner-city environments associated with the capacity to perform a safe displacement basedon decision-making process in autonomous navigation. It is designed a perception system that allows robotic-cars to drive autonomously on roads, with out the need to adapt the infrastructure,without requiring previous knowledge of the environment and considering the presenceof dynamic objects such as cars. It is proposed a novel method based on machine learning to extract the semantic context using a pair of stereo images, which is merged in an evidential grid to model the uncertainties of an unknown urban environment, applying the Dempster-Shafer theory. To make decisions in path-planning, it is applied the virtual tentacle approach to generate possible paths starting from ego-referenced car and based on it, two news strategies are proposed. First one, a new strategy to select the correct path to better avoid obstacles and tofollow the local task in the context of hybrid navigation, and second, a new closed loop control based on visual odometry and virtual tentacle is modeled to path-following execution. Finally, a complete automotive system integrating the perception, path-planning and control modules are implemented and experimentally validated in real situations using an experimental autonomous car, where the results show that the developed approach successfully performs a safe local navigation based on camera sensors

Full textAbstract:
The elderly population worldwide has an increasing expectation of wellbeing and life expectancy. The monitoring of the majority of elderly people on an individual basis, in a medical sense, will not be a viable proposition in the future due to the projected numbers of individuals requiring such activity. The expectation is that the infrastructure available will not be adequate to meet all the anticipated requirements and subsequently people will have to live at home with inadequate care. A new global objective that aims towards enhancing the quality of life of the elderly is being supported by extensive research. This research has been taking place in the field of ambient intelligence (AmI), considering factors including more comfort, improved health, enhanced security for the elderly, and facilitating the living in their homes longer. Prior research has shown a need for accelerated expansion in the ambient intelligence domain. To that end this work presents a novel learning technique for intelligent agents that can be used in Ambient Intelligent Environments (AIEs). The main objective of this work is to add knowledge to the AmI domain and to explore the practical applications within this research field. The added knowledge is accomplished through the development of an ambient intelligent health care environment that allows a practical assessment of the human well-being to take place. This is achieved by transforming the elderly living environment into an intelligent pseudo robot within which they reside to better understand the human wellbeing. The system developed aims to provide evidence that a level of automated care is both possible and practical. This care is for those with chronic physical or mental disabilities who have difficulty in their interactions with standardised living spaces. The novel integrated hardware and software architecture provides personalised environmental monitoring. It also provides control facilities based on the patient‘s physical and emotional wellness in their home. Entitled Health Adaptive Online Emotion Fuzzy Agent (HAOEFA), the system provides a non-invasive, self-learning, intelligent controlling system that constantly adapts to the requirements of an individual. The system has the ability to model and learn the user behaviour in order to control the environment on their behalf. This is achieved with respect to the changing environmental conditions as well as the user‘s health and emotional states being detected. A change of emotion can have a direct impact on the system‘s control taking place in the environment. Thus HAOEFA combines an emotion recognition system within a fuzzy logic learning and adaptation based controller. The emotion recogniser detects the occupant‘s emotions upon the changes of the physiological data being monitored. In addition to acting as an output to the occupant‘s physiological changes, the detected emotion also acts as input to the whole situation being observed by HAOEFA. This allows HAOEFA to control the Glam i-HomeCare on the user‘s behalf with respect to their emotional status. The system developed incorporates real-time, continuous adaptations to facilitate any changes to the occupant‘s behaviour within the environment. It also allows the rules to be adapted and extended online, assisting a life-long learning technique as the environmental conditions change and the user behaviour adjusts with it. HAOEFA uses the fuzzy c-means clustering methodology for extracting membership functions (MFs) before building its set of fuzzy rules. These MFs together with the rules base constitute a major part of the proposed system. It has the ability to learn and model the individual human behaviour with respect to their emotional status. Following the provided literature review and the presentation of Fuzzy logic MFs (see section 3.3). The thesis presents two chosen unobtrusive self-learning techniques that are used in the development of the intelligent fuzzy system. Each approach combines an emotion recogniser with a fuzzy logic learning and adaptation based technique for systems that can be used in AIEs. A comparison of two different MFs designs is contrasted showing the impact they have on the system learning ability. A number of carefully designed experiments were performed by volunteers in the Glam i-HomeCare test-bed at the University of South Wales to examine the system‘s ability to learn the occupant‘s behaviour with respect to their health and emotional states. The experimental procedures were performed twice by each volunteer, while maintaining the same behavioural actions to compare how much the design of fuzzy membership functions can impact the learning process and the number of rules created by the system. Besides evaluating both systems‘ emotion recognition accuracies and comparing them to one another for each occupant, the empirical outcomes show the potential of the approach in assisting the extension of independent living. The results demonstrate how the type-1 fuzzy system both learnt and adapted to each occupant‘s behaviour with respect to their health and emotional state whilst assessing multiple environmental conditions.

Full textAbstract:
With the availability of innumerable ‘intelligent’ building products and the dearth of inclusive evaluation tools, design teams are confronted with the quandary of choosing the apposite building control systems to suit the needs of a particular intelligent building project. The paucity of measures that represent the degree of system intelligence and indicate the desirable goal in intelligent building control systems design further inhibits the consumers from comparing numerous products from the viewpoint of intelligence. This thesis is organised respectively to develop models for facilitating the selection evaluation and the system intelligence analysis for the seven predominant building control systems in the intelligent building. To achieve these objectives, systematic research activities are conducted to first develop, test and refine the general conceptual models using consecutive surveys; then, to convert the developed conceptual frameworks to the practical models; and, finally, to evaluate the effectiveness of the practical models by means of expert validations.-----
The findings of this study, on one hand, suggest that there are different sets of critical selection criteria (CSC) affecting the selection decision of the intelligent building control systems. Service life, and operating and maintenance costs are perceived as two common CSC. The survey results generally reflect that an ‘intelligent’ building control system does not necessarily need to be technologically advanced. Instead, it should be the one that can ensure efficiency and enhance user comfort and cost effectiveness. On the other hand, the findings of the research on system intelligence suggest that each building control system has a distinctive set of intelligence attributes and indicators. The research findings also indicate that operational benefits of the intelligent building exert a considerable degree of influence on the relative importance of intelligence indicators of the building control systems in the models. This research not only presents a systematic and structured approach to evaluate candidate building control systems against the CSC, but it also suggests a benchmark to measure the degree of intelligence of one control system candidate against another.

En esta tesis se propone el uso de agentes inteligentes en entornos de aprendizaje en línea con el fin de mejorar la asistencia y motivación del estudiante a través de contenidos personalizados que tienen en cuenta el estilo de aprendizaje del estudiante y su nivel de conocimiento. Los agentes propuestos se desempeñan como asistentes personales que ayudan al estudiante a llevar a cabo las actividades de aprendizaje midiendo su progreso y motivación. El entorno de agentes se construye a través de una arquitectura multiagente llamada MASPLANG diseñada para dar soporte adaptativo (presentación y navegación adaptativa) a un sistema hipermedia educativo desarrollado en la Universitat de Girona para impartir educación virtual a través del web.
Un aspecto importante de esta propuesta es la habilidad de construir un modelo de estudiante híbrido que comienza con un modelo estereotípico del estudiante basado en estilos de aprendizaje y se modifica gradualmente a medida que el estudiante interactúa con el sistema (gustos subjetivos).
Dentro del contexto de esta tesis, el aprendizaje se define como el proceso interno que, bajo factores de cambio resulta en la adquisición de la representación interna de un conocimiento o de una actitud. Este proceso interno no se puede medir directamente sino a través de demostraciones observables externas que constituyen el comportamiento relacionado con el objeto de conocimiento. Finalmente, este cambio es el resultado de la experiencia o entrenamiento y tiene una durabilidad que depende de factores como la motivación y el compromiso.
El MASPLANG está compuesto por dos niveles de agentes: los intermediarios llamados IA (agentes de información) que están en el nivel inferior y los de Interfaz llamados PDA (agentes asistentes) que están en el nivel superior. Los agentes asistentes atienden a los estudiantes cuando trabajan con el material didáctico de un curso o una lección de aprendizaje. Esta asistencia consiste en la recolección y análisis de las acciones de los estudiantes para ofrecer contenidos personalizados y en la motivación del estudiante durante el aprendizaje mediante el ofrecimiento de contenidos de retroalimentación, ejercicios adaptados al nivel de conocimiento y mensajes, a través de interfaces de usuario animadas y atractivas. Los agentes de información se encargan del mantenimiento de los modelos pedagógico y del dominio y son los que están en completa interacción con las bases de datos del sistema (compendio de actividades del estudiante y modelo del dominio).
El escenario de funcionamiento del MASPLANG está definido por el tipo de usuarios y el tipo de contenidos que ofrece. Como su entorno es un sistema hipermedia educativo, los usuarios se clasifican en profesores quienes definen y preparan los contenidos para el aprendizaje adaptativo, y los estudiantes quienes llevan a cabo las actividades de aprendizaje de forma personalizada. El perfil de aprendizaje inicial del estudiante se captura a través de la evaluación del cuestionario ILS (herramienta de diagnóstico del modelo FSLSM de estilos de aprendizaje adoptado para este estudio) que se asigna al estudiante en su primera interacción con el sistema. Este cuestionario consiste en un conjunto de preguntas de naturaleza sicológica cuyo objetivo es determinar los deseos, hábitos y reacciones del estudiante que orientarán la personalización de los contenidos y del entorno de aprendizaje. El modelo del estudiante se construye entonces teniendo en cuenta este perfil de aprendizaje y el nivel de conocimiento obtenido mediante el análisis de las acciones del estudiante en el entorno.

Full textAbstract:
Present and future distributed applications need to deal with very large PetaBytes (PB) datasets and increasing numbers of associated users and resources. The emergence of Grid-based systems as a potential solution for large computational and data management problems has initiated significant research activity in the area. Grid research can be divided into two at least areas: Data Grids and Computational Grids. The aims of Data Grids are to provide services for accessing, sharing and modifying large databases, the aims of Computational Grids are to provide services for sharing resources. The considerable increase in data production and data sharing within scientific communities has created the need for improvements in data access and data availability. It can be argued the problems associated with the management of very large datasets are not well serviced by current approaches. The thesis concentrates on one of the areas concerned in the access to distributed very large databases on Grid resources. To this end, it presents the design and implementation of partial replication system and a Grid caching system that mediates access to distributed data. Artificial intelligent (AI) techniques such as a neural network (NN) have been used as a prediction element of the model to determine user requirements by analysing the past history of the user. Hence, this thesis will examine the problems surrounding the manipulation of very large data sets within a Grid-like environment The goal is the development of a prototype system that will enable both effective and efficient access to very large datasets, based on the use of a caching model.

Dell's computer manufacturing process involves a complex system of material flow and assembly. This includes intelligent replenishment of sub-components from local warehouses according to the manufacturing schedule, just-in-time manufacturing of custom configured computer systems including hard-drive image and custom software download, packaging the unit for delivery, order accumulation, and finally, distribution and shipping to the customer. This thesis examines Dell's current order fulfillment process and suggests methods that can help Dell meet or exceed customers' delivery time air shipments to certain destinations could be converted to less expensive ground shipments. However, this is only possible when the entire fulfillment process is integrated in such a way that eligible ground shipments meet their appropriate shipping windows. This analysis shows that optimizing these windows not only requires an examination of the average cycle time in each phase but also of the impact that cycle time variations have on the expectations at minimum logistics cost in the just-in-time environment. By manufacturing and shipping products based on certain times of the day, success of this air-to-ground conversion strategy. Through the use of simulation models I found that the key factors in reducing logistics cost require setting appropriate scheduling rules for each order size and reducing the cycle time variation.

La réalité virtuelle joue un rôle majeur dans le développement de nouvelles technologies de l’éducation, et permet de développer des environnements virtuels pour l’apprentissage, dans lesquels, des agents virtuels intelligents jouent le rôle de tuteur. Ces agents sont censés aider les utilisateurs humains à apprendre et appliquer des procédures ayant des objectifs d’apprentissage prédéfini dans différents domaines. Nous travaillons sur la construction d’un système temps-réel capable d’entamer une interaction naturelle avec un utilisateur dans un Environnement d’Apprentissage Virtuel (EAV). Afin d’implémenter ce modèle, nous proposons d’utiliser MASCARET (Multi-Agent System for Collaborative, Adaptive & Realistic Environments for Training) comme modèle d’Environnement Virtuel Intelligent (EVI) afin de représenter la base de connaissances des agents, et de modéliser la sémantique de l’environnement virtuel et des activités des utilisateurs. Afin de formaliser l’intention des agents, nous implémentons un module cognitif dans MASCARET inspiré par l’architecture BDI (Belief-Desire-Intention) qui nous permet de générer des intentions de haut-niveau pour les agents. Dans notre modèle, ces agents sont représentés par des Agents Conversationnels Animés (ACA), qui sont basés sur la plateforme SAIBA (Situation, Agent, Intention, Behavior, Animation). Les agents conversationnels de l’environnement ont des intentions communicatives qui sont transmises à l’utilisateur via des canaux de communication naturels, notamment les actes communicatifs et les comportements verbaux et non-verbaux. Afin d’évaluer notre modèle, nous l’implémentons dans un scénario pédagogique concret pour l’apprentissage des procédures d’analyse de sang dans un laboratoire biomédical. Nous utilisons cette application afin de réaliser une expérimentation et une étude pour valider les propositions de notre modèle. L’hypothèse de notre étude est de supposer que la présence d’un ACA dans un Environnement Virtuel (EV) améliore la performance du processus d’apprentissage (ou qu’au moins, ça ne le dégrade pas) dans le contexte de l’apprentissage d’une procédure spécifique. La performance de l’utilisateur est représentée par le temps requis pour l’exécution de la procédure, le nombre d’erreurs commises et le nombre de demande d’assistance. Nous analysons les résultats de cette évaluation, ce qui confirme partiellement l’hypothèse de l’expérience et affirme que la présence de l’ACA dans l’EV ne dégrade pas la performance de l’apprenant dans le contexte de l’apprentissage d’une procédureVirtual Reality plays a major role in developing new educational methodologies, and allows to develop virtual environments for learning where intelligent virtual agents play the role of tutors. These agents are expected to help human users to learn and apply domain-specific procedures with predefined learning outcomes. We work on building a real-time system able to sustain natural interaction with the user in a Virtual Learning Environment (VLE). To implement this model, we propose to use the Multi-Agent System for Collaborative, Adaptive & Realistic Environments for Training (MASCARET) as an Intelligent Virtual Environment (IVE) model that provides the knowledge base to the agents and model the semantic of the virtual environment and user’s activities. To formalize the intention of the agents, we implement a cognitive module within MASCARET inspired by BDI (Belief-Desire-Intention) architecture that permits us to generate high-level intentions for the agents. Furthermore, we integrate Embodied Conversational Agents (ECA), which are based on the SAIBA (Situation, Agent, Intention, Behavior, Animation) framework. The embodied agents of the environment have communicative intentions that are transmitted to the user through natural communication channels, namely the verbal and non-verbal communicative acts and behaviors of the ECAs. To evaluate our model, we implement it in a concrete pedagogical scenario for learning blood analysis procedures in a biomedical laboratory. We use this application to settle an experiment to validate the propositions of our model. The hypothesis of this experiment is to assume that the presence of anECA in a Virtual Environment (VE) enhances the learning performance (or at least does not degrade it) in the context of a learning procedure. The performance is represented by the time of execution, the number of committed errors and the number of requests for assistance. We analyze the results of this evaluation, which partially confirms the hypothesis of the experiment and assure that having an ECA in the VLE does not degrade the performance of the learner in the context of a learning procedure

Full textAbstract:
Building design is becoming an increasingly complex process. Technological advances in building materials and construction methods have necessitated the specification of more rigourous regulatory constraints to which the designer must adhere. Although a diverse range of sophisticated computer based design tools, addressing the formal functional requirements of building design, exist to assist the designer in the decision making process, as a result of their sophistication, such tools often require considerable specialist knowledge of the methodologies employed before they can realistically be utilized on a routine basis. As a result a growing interest has developed in intelligent user-interfaces in an attempt to make complex application software more accessible, maintainable and extendible. However, owing to inconsistencies between front-ends, the current trend in user interface management systems tends to propagate the encapsulation of application functionality within a static, esoteric style of dialogue; restricting interaction to the lowest common user level and therefore denying the designer unrestricted access to the embedded methodologies required for creative solution synthesis. By adopting a communications view of the user-interface, this thesis illustrates how a dynamically adaptable user-interface, coupled to a multi-level knowledge based system consisting of surface level models derived from human laws, with deep models of reasoning, employing non-procedural, opportunistic knowledge acquisition mechanisms, may be utilised to accommodate the dynamically varying nature of the design process. The resulting object oriented framework is an intelligent design support system which isolates the user from the low level aspects of CAD tool management; enabling experts from different sub-disciplines to access the functionality of a comprehensive range of design tools in manner suited to their individual conceptual vocabulary, level of expertise, and idiosyncratic design procedures. Although the framework described within this thesis is generally applicable across a range of domains, specific examples of user stereotypes and dialogue templates used to illustrate the principles behind the system are derived from building performance assessment and prediction.

The US Navy is shifting to power projection from the sea which stresses the capabilities of its current fleet and exposes a need for a new surface connector. The design of complex systems in the presence of changing requirements, rapidly evolving technologies, and operational uncertainty continues to be a challenge. Furthermore, the design of future naval platforms must take into account the interoperability of a variety of heterogeneous systems and their role in a larger system-of-systems context. To date, methodologies to address these complex interactions and optimize the system at the macro-level have lacked a clear direction and structure and have largely been conducted in an ad-hoc fashion. Traditional optimization has centered around individual vehicles with little regard for the impact on the overall system. A key enabler in designing a future connector is the ability to rapidly analyze technologies and perform trade studies using a system-of-systems level approach.
The objective of this work is a process that can quantitatively assess the impacts of new capabilities and vessels at the systems-of-systems level. This new methodology must be able to investigate diverse, disruptive technologies acting on multiple elements within the system-of-systems architecture. Illustrated through a test case for a Medium Exploratory Connector (MEC), the method must be capable of capturing the complex interactions between elements and the architecture and must be able to assess the impacts of new systems). Following a review of current methods, six gaps were identified, including the need to break the problem into subproblems in order to incorporate a heterogeneous, interacting fleet, dynamic loading, and dynamic routing. For the robust selection of design requirements, analysis must be performed across multiple scenarios, which requires the method to include parametric scenario definition.
The identified gaps are investigated and methods recommended to address these gaps to enable overall operational analysis across scenarios. Scenarios are fully defined by a scheduled set of demands, distances between locations, and physical characteristics that can be treated as input variables. Introducing matrix manipulation into discrete event simulations enables the abstraction of sub-processes at an object level and reduces the effort required to integrate new assets. Incorporating these linear algebra principles enables resource management for individual elements and abstraction of decision processes. Although the run time is slightly greater than traditional if-then formulations, the gain in data handling abilities enables the abstraction of loading and routing algorithms.
The loading and routing problems are abstracted and solution options are developed and compared. Realistic loading of vessels and other assets is needed to capture the cargo delivery capability of the modeled mission. The dynamic loading algorithm is based on the traditional knapsack formulation where a linear program is formulated using the lift and area of the connector as constraints. The schedule of demands from the scenarios represents additional constraints and the reward equation. Cargo available is distributed between cargo sources thus an assignment problem formulation is added to the linear program, requiring the cargo selected to load on a single connector to be available from a single load point.
Dynamic routing allows a reconfigurable supply chain to maintain a robust and flexible operation in response to changing customer demands and operating environment. Algorithms based on vehicle routing and computer packet routing are compared across five operational scenarios, testing the algorithms ability to route connectors without introducing additional wait time. Predicting the wait times of interfaces based on connectors en route and incorporating reconsideration of interface to use upon arrival performed consistently, especially when stochastic load times are introduced, is expandable to a large scale application. This algorithm selects the quickest load-unload location pairing based on the connectors routed to those locations and the interfaces selected for those connectors. A future connector could have the ability to unload at multiple locations if a single load exceeds the demand at an unload location. The capability for multiple unload locations is considered a special case in the calculation of the unload location in the routing. To determine the unload location to visit, a traveling salesman formulation is added to the dynamic loading algorithm. Using the cost to travel and unload at locations balanced against the additional cargo that could be delivered, the order and locations to visit are selected. Predicting the workload at load and unload locations to route vessels with reconsideration to handle disturbances can include multiple unload locations and creates a robust and flexible routing algorithm.
The incorporation of matrix manipulation, dynamic loading, and dynamic routing enables the robust investigation of the design requirements for a new connector. The robust process will use shortfall, capturing the delay and lack of cargo delivered, and fuel usage as measures of performance. The design parameters for the MEC, including the number available and vessel characteristics such as speed and size were analyzed across four ways of testing the noise space. The four testing methods are: a single scenario, a selected number of scenarios, full coverage of the noise space, and feasible noise space. The feasible noise space is defined using uncertainty around scenarios of interest. The number available, maximum lift, maximum area, and SES speed were consistently design drivers. There was a trade-off in the number available and size along with speed. When looking at the feasible space, the relationship between size and number available was strong enough to reverse the number available, to desiring fewer and larger ships. The secondary design impacts come from factors that directly impacted the time per trip, such as the time between repairs and time to repair. As the noise sampling moved from four scenario to full coverage to feasible space, the option to use interfaces were replaced with the time to load at these locations and the time to unload at the beach gained importance. The change in impact can be attributed to the reduction in the number of needed trips with the feasible space. The four scenarios had higher average demand than the feasible space sampling, leading to loading options being more important. The selection of the noise sampling had an impact of the design requirements selected for the MEC, indicating the importance of developing a method to investigate the future Naval assets across multiple scenarios at a system-of-systems level.

Thesis (M. Tech.) -- Central University of Technology, Free State, 2010Traditional corrective maintenance is both costly and ineffective. In some situations it is more cost effective to replace a device than to maintain it; however it is far more likely that the cost of the device far outweighs the cost of performing routine maintenance. These device related costs coupled with the profit loss due to reduced production levels, makes this reactive maintenance approach unacceptably inefficient in many situations. Blind predictive maintenance without considering the actual physical state of the hardware is an improvement, but is still far from ideal. Simply maintaining devices on a schedule without taking into account the operational hours and workload can be a costly mistake. The inefficiencies associated with these approaches have contributed to the development of proactive maintenance strategies. These approaches take the device health state into account. For this reason, proactive maintenance strategies are inherently more efficient compared to the aforementioned traditional approaches. Predicting the health degradation of devices allows for easier anticipation of the required maintenance resources and costs. Maintenance can also be scheduled to accommodate production needs. This work represents the design and simulation of an intelligent maintenance management system that incorporates device health prognosis with maintenance schedule generation. The simulation scenario provided prognostic data to be used to schedule devices for maintenance. A production rule engine was provided with a feasible starting schedule. This schedule was then improved and the process was determined by adhering to a set of criteria. Benchmarks were conducted to show the benefit of optimising the starting schedule and the results were presented as proof. Improving on existing maintenance approaches will result in several benefits for an organisation. Eliminating the need to address unexpected failures or perform maintenance prematurely will ensure that the relevant resources are available when they are required. This will in turn reduce the expenditure related to wasted maintenance resources without compromising the health of devices or systems in the organisation.

Thesis (M.Tech.) - Central University of Technology, Free State, 2007The latest technological trend worldwide, is automation. Reducing human labour and introducing robots to do the work is a pure business decision. The reason for automating a plant can be some, or all, of the following: Improve productivity Reduce labour and equipment costs Reduce product damage System reliability can be monitored Improves plant safety When the automation process is started, Automatic Guided Vehicles (AGVs) will be one of the first commodities that can be used. The reason for this is that they are so versatile. They can be programmed to follow specific paths when moving material from one point to another and the biggest advantage of all is that they can operate for twenty four hours a day. Automatic Guided Vehicles are developed for many different applications and therefore many different types of AGVs are available. All AGVs are equipped with sensors so that they are able to “see” what is happening around them. Since the AGV must be able to function without any human help or control, it must be able to navigate through the work environment. In this study a remote control car was converted to an AGV and thorough research was done on the different types of sensors that can be used to make the AGV more intelligent when it comes to navigating in an unknown environment.

Full textAbstract:
The architecture of change bears in its name the vision and the hope of an architecture that has evolved from a static deterministic designer-defined disposition, where a user has to adapt to a given setting, to an interactive architecture that adapts to the needs of the user. Yet, built examples show that the reality of intelligent houses is not as open-minded as the theory would have us believe. Often, the flexibility and freedom of choice is, in fact, just a way to control the users. Looking at the evolving user models in modern architectural history, strategies to liberate the user from the designer's determinism in static architecture are identified and compared. One of the limitations of these strategies - the one-way communication through architecture - finally seems to be addressed through interactive architecture. Moreover, quantification of everyday habits brings the potential of architecture as a new form of experience. Contrary to public interactive architecture projects, which are much discussed and well documented, the interactive projects in the private realm are less well documented and the experiences of their users less well known. Thereby, the findings and experiences of interactive projects in the public realm cannot be simply transferred into the private realm, as the virtues that we take for granted in homes, such as privacy, security or trust, are challenged with the digitalisation of the house. To compensate for the deficit of examples in the private realm, different strategies are used: an inquiry of user models in interactive architecture compared with findings on user models in static architecture allows for the definition of new user categories in interactive architecture; examples in interactive architecture are juxtaposed with lessons learnt regarding user habits on the Internet allowing, at certain points, reviews of thought experiments (Gedankenexperimente) to test the relevance of certain theories in scenes of normal life. One of the central statements of the thesis is that interactive architecture currently tends to abstract the user even more by translating all human actions into digital models, thus, not only alienating the designers from the real-life users but also estranging the users from themselves through imposed roles in these digital environments. Against such tendencies, the embodiment of the user can play a key role, both in design and in the implementation of interactive architecture. In homes this might be crucial, as the thesis shows that interactions with digital environments, where embodiment doesn't play a role, seem to make the users less wary. Instead of abstracting the user, technology has the potential to help propagate the awareness of the user in their environment. Moreover, contrary to current day tendencies of overburdening the user with signals, this can also happen unconsciously, as proposed with architectural atmospheres.

Full textAbstract:
In a time of fast growing technology and communication systems, it is very important for the industry and the corporations to develop new contact centre environment technologies for better customer contact requirements. The integration of contact centre (CC) into day-to-day organisational operations represents one of the most promising trends in the 21 st century economy. Whatever the nature or point of contact, customers want a seamless interaction throughout their experience with the company. Customers receive more personalised experience, while the company itself can now provide a consistent message across all customer interactions. Based on the literature studies and the research carried out within the contact centre industry through the case studies, the author identified the customer and advisor behavioural attributes along with demographic, experience and others that later are used to derive the categories. Clustering technique identified the categories for customers and advisors. From the initial set of categories, fuzzy expert system framework was derived which assigned a customer or advisor with the pre-defined set of categories. The thesis has proposed two novel frameworks for categorisation of customer and advisor within contact centres and development of intelligent decision support framework that displays the right amount of information to the advisor at the right time. Furthermore, the frameworks were validated with qualitative expert judgement from the experts at the contact centres and through a simulation approach. The research has developed a novel Soft Computing based fuzzy logic categorisation framework that categorises customer and advisor on the basis of their demographic, experience and behavioural attributes. The study also identifies the behavioural aspects of customer and advisor within CC environment and on the basis of categorisation framework, assigns each customer and advisor to that of a pre-defined category. The research has also proposed an intelligent decision support framework to identify and display the minimum amount of information required by an advisor to serve the customer in CC environment. The performance of the proposed frameworks is analysed through four case studies. In this way this research proposes a fully tested and validated set of categorisation and information requirement frameworks for dealing with customer and advisor and its challenges. The research also identifies future research directions in the relevant areas.

Full textAbstract:
Significant advances have been achieved in the fields of medical informatics and artificial intelligence in medicine in the past three decades and, having demonstrated an ability to support clinical decisions, knowledge-based systems are becoming increasingly ubiquitous in various clinical settings. Nonetheless, few systems have so far been successful in entering routine use. On the one hand, primarily due to methodological difficulties and with very few exceptions, developers have failed to show that pertinent systems are effective in improving patient care. On the other hand, support systems have not been sufficiently well integrated into the routine information processing activity of the clinical users. As a consequence, their clinical utility is disputed and constructive assessmenist further hindered. This thesis describes the development of an intelligent clinical information management support system designed to overcome these obstacles through the adoption of an integrated approach, geared toward the solution of the problems encountered in the acquisition, organisation, review and interpretation of the clinical decision supporting information utilised in the process of monitoring intensive care unit patients with acid-base balance disorders. The system was developed to support this activity incrementally, using the methods of object-oriented analysis, design and implementation, with the active participation of a clinical advisor who assessed the functional and ergonomic compatibility of the system with the supported activity and the integration of a previously validated prototype knowledge-based data interpretation system, which could not evaluated in the clinical setting for the reasons described above.

Full textAbstract:
The lack of a buildability evaluation at the design stage coupled with the separation of the design and construction processes have been acknowledged to cause buildability problems on site. Normally, designers view of their task, is to develop a masterpiece which satisfies the functional requirements of a project while constructors consider their task as construction works, which need to be completed at the lowest price. No significant efforts have been made to bring the design and construction processes together to facilitate the integration of information for the improvement of the overall project performance. This study proposes an integrated framework for construction planning which is capable of exchanging information with other construction disciplines and generating planning information in an integrated construction environment. Planning data and processes were first modelled using object oriented analysis methodology, i.e. Martin (1993), where the emphasis was placed on both the data and its behaviour. This development was carried out within a general integrated framework which facilitates the integration between the various construction application across the project life cycle. The developed models highlight the importance and the role of the planning process which is vital in providing relevant information to other disciplines. Moreover, the study proposes a quantitative approach for a buildability evaluation based on the information available within the integrated environment. It evaluates the design solutions from the construction view, as outlined in the construction plan. The qualitative principles of buildability improvements were adopted to formalise this approach. A combination of weightings and scores were assigned to building elements to reflect their buildability factors. The developed data and process models, were implemented in an object oriented environment as part of a single integrated construction environment SPACE (Simultaneous Prototyping for An Integrated Construction Environment) where CONPLAN (Intelligent CONstruction PLANning for design rationalisation) is one of the SPACE modules. CONPLAN automatically generates the construction planning information and the buildability reports. The former can be dynamically accessed either through a planning package or visualised in a virtual space using a virtual reality package. The buildability reports can be either displayed in a textual or graphical format.

Full textAbstract:
Ship weather routing was first developed for determining the minimum time of a voyage. However, after 90's, driven by the increasing oil price and the environmental considerations, most shipping companies have began to show more and more interest in minimising fuel consumption in a route, in the meantime, maintaining a certain time schedule which is specified in the chartering contract of a merchant vessel. This topic is the focus of this thesis. A novel three dimensional dynamic programming method (3DDP) has been developed in this research to determine the optimised ship course and its corresponding engine power for minimum fuel consumption. During the optimisation process, Kwon's method as a new empirical formula is used to calculate ship speed in different weather conditions and an IMO guideline is applied to ensure ship safety during a voyage. In addition to the 3DDP method developed, three multi-objective evolutionary algorithms (MOEAs) are also proposed to treat we ather routing as a multi-objective and constrained optimisation problem. Based on ship hydrodynamic knowledge and optimisation algorithms an Intelligent Tool for Energy Efficient and low environment impact Shipping (ITEES) has been developed. ITEES is established by using the object-oriented software development theory, consisting of several independent functional modules. The OPeNDAP as an advanced communication technique is employed by ITEES for downloading deterministic weather forecast at no cost. Case studies are given in Chapter 8 of this thesis to evaluate the performance of the 3DDP method in a comparison with other different optimisation algorithms under different weather conditions. A 54,000 DWT container ship is used as the case ship. The case studies have demonstrated that, in medium sea condition, different route optimisation methods offer the similar results that the shortest route with a constant engine power brings the lowest fuel consumption. However, the results of different route optimisation methods vary significantly in rough sea states. Optimised results are not only just for fuel saving but also, most importantly, for ensuring ship safety during a voyage. Among the optimisation algorithms evaluated by the research, the 3DDP used in ITEES is able to give a better performance for fuel saving than other methods. In addition, it has the characteristics of using straight forward theory and less parameter settings compared with MOEAs that make the ITEES programme easy and convenient for operators to use.
