Abstract:
A prototype Climate Information System (CIS) is developed to manage and display climatic data as part of the Navy's Tactical Environmental Support System (TESS). The CIS reduces the time and effort required to locate, ingest and analyze climatic data. The CIS remedies accessibility problems of existing climatologies by using a Data Base Management System (DBMS) to manage on-line data sets. The CIS computer graphics improve data comprehensibility by remapping data to common projections. The CIS design rationale and implementation methodology are documented. The climatic data requirements for TESS are defined. The CIS capabilities are demonstrated with sample data sets which meet some of these requirements. The CIS design allows additional data sets to be added as needed

Abstract:

Inbyggda system blir allt vanligare i dagens samhälle. De inbyggda systemen finns i nästan allt nuförtiden, från diverse fordon till leksaker för barn.

Dagens teknik innebär bland annat att gårdagens lösningar kan realiseras på en bråkdel av den tidigare ytan. Allt mer blir ytmonterat med mindre och mer komplexa kretsar. Detta är inte alltid till utvecklarnas fördel då montering av prototypkort blir en svår och/eller dyr process.

Målet är att ta fram ett inbyggt system med en ARM-processor. Systemet ska innehålla USB-OTG, ethernet, minne av olika slag som FRAM och microSD samt en display med pekskärm för användargränssnitt. Projektet omfattar allt från komponentval till test och verifiering med programkod.

Tiden räckte inte till för att få med alla delar som planerats. Resultatet av projektet blev ett prototypkort och två små programsekvenser, en som blinkar två lysdioder på kortet och en som skriver ut en bild på displayen.

Detta inbyggda system är i första hand till för utvärdering av ARM-processorer för Mikrodidakt AB.


Embedded systems has become more and more common in today's society. The embedded systems are included in almost everything today, from various vehicles to children's toys.

Today's technology means that yesterday's solutions can be realised on a fraction of the area. More and more become surface mounted with smaller and more complex circuits. This is not always an advantage for the developers when assembling and soldering prototype circuit boards become a more difficult and/or an expensive process.

The goal is to create an embedded system with an ARM-processor. The system will consist of USB-OTG, ethernet, various memory like FRAM and microSD and a display with touchscreen for user interface. The project includes everything from choice of components to test and verification with program code.

The time was too short to include all the parts that was planned. The result of the project was a prototype card and two small program sequences, one that blinks the two light diodes on the card and one that writes a picture on the display.

This embedded system is intended for evaluating ARM-processors by Mikrododakt AB.

Abstract:

Though a constantly increasing number of ontologies are now available on the Internet, the ontology construction process remains generally a manual task, so consequently an effort demanding task. As no unified ontology construction method is available in the literature, researchers started investigating different frameworks for automatically generating ontologies and, therefore shorten the time required for their construction. This master’s thesis presents a prototype system for automatic construction of ontology, based on ontology design patterns and unstructured texts, such as natural language texts. The use of ontology design patterns allow constructing well structured ontologies and reducing the demand of knowledge experts. A difference between our prototype system and the systems presented in the literature is, the possibility to increase accuracy of the generated ontology by selecting the more relevant terms and associations from the unstructured text and match them against the ontology design patterns. Also, a matching score is introduced to define the level of similarity between the terms extracted and the ontology design patterns. By setting a threshold value on the matching score, the relevant ontology design patterns are selected and used for the ontology construction process. The ontology construction framework used by the prototype system has been developed by the research group in Information Engineering of the School of Engineering, Jönköping University.

Även fast ett ökande antal ontologier är tillgängliga på Internet, är ontologikonstruktion fortfarande till största delen en manuell process, som därigenom kräver en stor arbetsinsats. Eftersom ingen enhetlig metodologi för att konstruera ontologier finns i litteraturen, forskare började undersöka olika ansatser för att automatiskt generera ontologier och därigenom förkorta konstruktionstiden. Detta examensarbete presenterar ett prototypsystem för automatisk konstruktion av ontologier, baserat på designmönster för ontologier och ostrukturerad text (text i naturligt språk). Att använda designmönster ger en välstrukturerad ontologi och minskar behovet av expertkunskap. En skillnad mellan vårt system och system i litteraturen är möjligheten att få en mer korrekt ontologi genom att välja de mestrelevanta termerna och relationerna från texterna och matcha dem motdesignmönstren. Ett värde för överensstämmelsen har införts för att kunna beskriva hur stor likhet som finns mellan termerna och designmönstren. Genom att sätta ett tröskelvärde väljs de relevanta designmönstren ut och används för att konstruera ontologin. Den generella processen för ontologikonstruktion som används av prototypsystemet har utvecklats av forskningsgruppen i Informationsteknik vid Ingenjörshögskolan i Jönköping.

Full text
Abstract:
A prototype data acquisition and processing system is developed for evaluating the insulation condition of a power transformer winding in real-time. The Transformer Insulation Condition Monitoring System (TICMS) evaluates the insulation condition by calculating the winding transadmittance function. The winding transadmittance function is used to fingerprint the insulation system and provides a means of monitoring its condition. The use of a transfer function for evaluating the insulation condition of a power transformer winding was proposed by Malewski and Poulin in 1988 [6, Chapter 1]. The work described in this thesis extends their work in a number of important areas and makes the following contributions to the state-of-the-art. Firstly, the TICMS is able to calculate the transadmittance function to 3MHz, which is sufficient to detect breakdown between individual turns in an Extra High Voltage (EHV) transformer. This is a key distinguishing feature of this work and is important as faults between individual turns can quickly snowball into a catastrophic failure. Previous attempts have been successful at determining the transadmittance function to around 1.5MHz, which only allows breakdown between discs to be detected in an EHV transformer. Second, the TICMS is able to determine the transadmittance function on-line and in real-time for a fully energised transformer. This is another key distinguishing feature of this work as it allows action to be taken to remove a faulty transformer from service prior to catastrophic failure. Previous attempts have calculated the transadmittance function in an offline situation over a period of minutes using pre-recorded data. Recent advances in analog-to-digital converter (ADC) technology and the availability of high speed Digital Signal Processors (DSPs) have made it possible to extend the work of Malewski and Poulin as described above. This thesis describes the key design features of the TICMS which provide it with the ability to determine the transadmittance function over a 3MHz bandwidth in real-time. These features include the application of an excitation with tailored spectral characteristics, a novel transducer arrangement that allows the effective dynamic range of the digitizer to be extended and at the same time online measurements to be performed, a first-in-first-out (FIFO) memory arrangement that allows the high speed data acquisition section to easily interlace to the data processing section, and a powerful 32-bit floating point Digital Signal Processor (DSP) that enables the trans admittance function to be determined in real-time. The graphical user interlace to the laboratory prototype is also presented. Also described are the signal processing techniques, both applied and developed, that are used by the TICMS to determine the trans admittance function in real-time. These include the deconvolution of the voltage and current channel transducer output signals, a radix-2 decimation-in-time (DIT) fast Fourier transform (FFT) algorithm that transforms the voltage and current channel inputs into the frequency domain simultaneously, the calculation of the transadmittance function magnitude and phase from the recorded transients, and a zooming algorithm that is used to accurately determine pole height. The transadmittance function of a 7.5kVA 11kV/230V distribution transformer is determined and compared with that obtained by performing a time consuming sweep frequency test. Artificial faults are inserted into a 2nd 7.5kVA 11kV/230V distribution transformer to establish relationships between the location and size of a fault and the corresponding changes in the transadmittance function. Sets of tests are conducted to evaluate the effect of fault size, fault location, the introduction of simulated partial discharges, and single turn faults. The ability of the system to detect single turn faults is a key feature as this allows faults to be detected before they can snowball into catastrophic failures. The effect of temperature on the location and height of poles in the transadmittance function of a 7.5kVA 11kV/220V distribution transformer is established through the use of the TICMS. On-line testing of an energised transformer is performed to evaluate the effect of supply voltage magnitude, load current magnitude, and the point in the 50Hz AC cycle when the insulation test is initiated. This information allows the system to compare successive transadmittance functions and generate an alarm signal if insulation condition degradation is found to have taken place. This information will allow the system to eventually become a 'black box' that permanently sits beside a transformer continuously evaluating insulation condition.

Abstract:
Increased pressure on high voltage power distribution components has been created in recent years by a demand to lower costs and extend equipment lifetimes. This has led to a need for condition based maintenance, which requires a continuous knowledge of equipment health. Power transformers are a vital component in a power distribution network. However, there are currently no established techniques to accurately monitor and diagnose faults in real-time while the transformer is on-line. A major factor in the degradation of power transformer insulation is partial discharging. Left unattended, partial discharges (PDs) will eventually cause complete insulation failure. PDs generate a variety of signals, including electrical pulses that travel through the windings of the transformer to the terminals. A difficulty with detecting these pulses in an on-line environment is that they can be masked by external electrical interference. This thesis develops a method for identifying PD pulses and determining the number of PD sources while the transformer is on-line and subject to external interference. The partial discharge detection system (PDDS) acquires electrical signals with current and voltage transducers that are placed on the transformer bushings, making it unnecessary to disconnect or open the transformer. These signals are filtered to prevent aliasing and to attenuate the power frequency, and then digitised and analysed in Matlab, a numerical processing software package. Arbitrary narrowband interference is removed with an automated Fourier domain threshold filter. Internal PD pulses are separated from stochastic wideband pulse interference using directional coupling, which is a technique that simultaneously analyses the current and voltage signals from a bushing. To improve performance of this stage, the continuous wavelet transform is used to discriminate time and frequency information. This provides the additional advantage of preserving the waveshapes of the PD pulses for later analysis. PD pulses originating within the transformer have their waveshapes distorted when travelling though the windings. The differentiation of waveshape distortion of pulses from multiple physical sources is used as an input to a neural network to group pulses from the same source. This allows phase resolved PD analysis to be presented for each PD source, for instance, as phase/magnitude/count plots. The neural network requires no prior knowledge of the transformer or pulse waveshapes. The thesis begins with a review of current techniques and trends for power transformer monitoring and diagnosis. The description of transducers and filters is followed by an explanation of each of the signal processing steps. Two transformers were used to conduct testing of the PDDS. The first transformer was opened and modified so that internal PDs could be simulated by injecting artificial pulses. Two test scenarios were created and the performance of the PDDS was recorded. The PDDS identified and extracted a high rate of simulated PDs and correctly allocated the pulses into PD source groups. A second identically constructed transformer was energised and analysed for any natural PDs while external interference was present. It was found to have a significant natural PD source.

A suspension system was designed to make The Rickshaw Bank's bicycle-powered rickshaws more comfortable for the drivers. A four bar linkage with a rising rate spring was chosen as the design. An unconventional material-tire rubber-was used as the spring material because it is inexpensive, requires limited tooling, and is in vast supply near The Rickshaw Bank's factory in Assam, India. Different configurations of tire rubber were tested to see how the size, length, and placement of the spring affected the system's performance. Bode Plots of the system's response function were generated for each configuration. The functionality of the suspension system within the 10-20 Hz range was of premier importance because it is in this frequency range that the bicycle-powered rickshaws most often operate, based on their speed and the road conditions the rickshaw regularly encounters. Ultimately, it was demonstrated that the placement of the spring within the suspension system had the greatest effect on the system's response. The configuration that applied the greatest moment to the top link of the four bar linkage performed best. Surprisingly, any advantages arising from varying the geometry of the tire rubber pieces were lost to friction and the effect of the ply embedded in the tire rubber. In order to properly verify the optimal spring placement and tire rubber spring geometry, a suspension system that takes this paper's findings into account should be tested with a rickshaw in India.

Abstract:
This thesis presents the theory, methodology and results of building, tuning and testing a prototype for controlling body roll movement. Body roll is a result of lateral acceleration that acts on a vehicle when turning and result in torque on the roll center of the vehicle. The objective of this thesis is, in collaboration with Freno Air AB [7], to build a prototype and, with the help of sensors and micro controllers, restrict the body roll to avoid roll over on a semi-trailer that the company builds. The control unit in this thesis includes two PID controllers that is vastly used today in many different applications. The control unit is fed with signals from two pressure sensors on each side of the prototype frame. The pressures are given by four syringes, two on each side that are connected to the pressure sensors. One PID has small gains of KP = 0.2, KD = 0.005 and KI = 0 to take care of smaller and slower variations of pressure difference and one PID with higher gains of KP = 1, KD = 1 and KI = 0 to take care of faster and bigger variations in pressure difference which in both of the cases the pressure difference translates to body roll. The pressures give is enough of information of the prototypes state to be able to control it with the help of a motion platform that is able to roll in opposite direction to equalize the pressures. The results for the two cases of slow roll and fast roll are promising with a fast response, few oscillations and overshoots, which makes the system fast and stable, two things that are opposites in the world of closed loop control. The experiment was performed in a stationary form with applied disturbances and actuated with a motion platform capable of roll rotation.

In a technology driven world, efforts are being made to make education/learning available to individuals at any time with no compromise in the quality of teaching/training. To make learning flexible, different techniques such as distributing learning material, uploading audio lectures on the web, and creating intelligent tutoring systems (ITS) are being used. The technique considered here is an adaptive ITS, a system that replicates the learning that occurs in a student teacher relationship. This thesis develops an adaptive intelligent tutoring system architecture prototype where the addition, modification and removal of educational material are relatively easy. The resulting software will take into account: the goals of the specific educational experience, the concepts to be covered, the preferred learning style of the student, measures to detect misuse of the system functionality, behavior based on the student's performance and the generation of hint sequences and feedback messages to improve learning gain. The system will accomplish these objectives by assessing the student's prior knowledge level, observing the actions performed by the student and by adapting to his/her learning abilities. The ITS will attempt to be more intelligent by performing some actions traditionally done by a human teacher - such as diagnosing misconceptions, identifying the most suitable learning style, stressing concepts that the student is finding difficult to understand, switching back to the learning material if the student shows no improvement after a set of trials. The system makes sure that the student is getting feedback where appropriate. Using this prototype system, the student will be tutored to acquire declarative knowledge. A problem based learning (PBL) approach will be used to strengthen the acquired knowledge by providing a high degree of personal attention to the student. To show how the prototype system works, an example of analysis of a control system problem using bode plot technique will be used to assist the student in using the technique to perform the stability analysis of an analog, linear, time-invariant control system problems and to recommend a controller to attain stability (if the system is not stable). Ideas of porting the system from standalone to web-based architecture and features required for collaborative learning will be discussed and an architecture for a web-based tutoring system for supporting multiple students enabling communication between students and sharing data among them will be proposed.

Abstract:

When two distributed parties want to share information stored in ontologies, they have to make sure that they refer to the same concepts. This is done matching the ontologies.

This thesis will show the implementation of a method for automatic ontology matching based on the representation of polygons. The method is used to compare two ontologies and determine the degree of similarity between them.

The first of the ontologies will be taken as the standard, while the other will be compared to it by analyzing the elements in both. According to the degrees of similarity obtained from the comparison of elements, a set of polygons is represented for the standard ontology and another one for the second ontology.

Comparing the polygons we obtain the final result of the similarity between the ontologies.

With that result it is possible to determine if two ontologies handle information referred to the same concept.

Abstract:
Tracking of an object in six degrees-of-freedom (DOF) produces a position and orientation estimate of the object as it moves in 3D space. This thesis investigates the design and implementation of a prototype optical 6 DOF tracking system. Although optical scanners potentially have issues regarding occlusion they have advantages over electromagnetic scanners in that they can be used without distortion near ferromagnetic materials and can have large working volumes. This thesis focuses on the design of a small camera module named the ‘Black Spot’ that forms part of the overall tracking system. This module is capable of tracking the locations of up to 27 LED markers at 60 frames/s as the module moves in space. These markers provide fixed reference points that are utilised by the tracking system. A number of these modules will, in future revisions of the system, be clustered closely together forming a tracking hub. In this research this hub has been partially implemented in software on a PC. This software implements a ‘pose estimation’ algorithm that iteratively refines the location and position of the camera modules. Results from testing three Black Spot modules indicates that the locations of the LED markers can be determined very precisely using a centroid calculation. Standard deviations of better than 0.01 pixels have been recorded using these modules. The pose estimation algorithm has been tested revealing the need for a better minimisation algorithm. It is recommended that a bundle adjustment algorithm is used in the future to refine the world model used by the hub. The calibration of the system is a task for future research.

Abstract:
Approved for public release; distribution is unlimited
The Monterey Security Architecture (MYSEA) provides a distributed multilevel secure (MLS) environment consisting of a MLS local area network (LAN) and multiple single-level networks. The MYSEA server enforces a mandatory access control policy to ensure that users can only access data for which they are authorized. Intrusion detection systems (IDS) placed on a single-level network can store the alerts in the IDS databases at the same classification level as the network being monitored. As most databases do not support the enforcement of mandatory security policies, access to these databases is restricted to singlelevel access only. Thus, administrators are not presented with a coherent view of IDS alerts from all of the connected networks. The objective of this thesis is to design a database proxy to allow administrators to view and analyze IDS information at multiple classification levels while enforcing the systems overall mandatory policy. Based on the derived concept of operations and the requirements, a design for the database proxy that mediates access to databases at different levels was conceived. A prototype database proxy was implemented along with modifications to a web-based analysis tool to allow the viewing and analysis of IDS information at multiple classification levels.

This thesis examines the feasibility of using an expert system to solve the threat identification problem in the radar signal environment. Such systems can be used to support the Electronic Warfare Officer (EWO) in decision- making. We have analyzed the expertise required in electronic warfare (EW) and have identified key signal parameters. In addition, we have devised a method called function recognition to facilitate radar signal analysis. A rule-based prototype system possessing EW knowledge has been designed and developed for a micro-computer system using the expert system shell CLIPS. The system is able to receive preprocessed sensor inputs, determine the radar signals that are present, perform threat target identification, and suggest the best possible electronic counter measures. The behavior of the system is demonstrated using several hypothetical EW scenarios. We believe that such a system can be incorporated as an electronic warfare (EW) subsystem. (Author)

Abstract:
This thesis is concerned with a prototype gravitational wave data analysis system. Work will shortly be underway on the construction of large scale broad-band laser interferometers that should produce data containing gravitational waves. Subsequently, systems that can analyse this data, extracting any waves within the noise, need to be developed now. The prototype system described in this thesis is the first fully automated gravitational wave data analysis system to be developed. It is designed in parallel, to run on several processors simultaneously, as future systems are certain to employ parallelism to some degree. This thesis is also concerned with the analysis of actual data by this system, produced by the prototype interferometer owned and operated by the University of Glasgow. The software is described in detail, beginning with a description of the parallelism within the sys­tem. The procedure employed to split the multiplexed data into its constituent streams is discussed followed by a description of the methods employed to optimise the detector noise for the extraction of possible signals from short duration gravitational wave bursts. This is followed by a description of both the statistical analysis and the search for events carried out on the calibrated and optimally weighted interferometer stream. This search looks for wideband burst events in the time series and also coalescing binary signals found by cross-correlating the noise with a bank of templates. An account of the results of the analysis is given, concentrating on the statistics of detector noise, identifying its main characteristics both when the detector is operating properly and also when the housekeeping data suggests it is not. A description is given of a parameter, easily calculated from the noise, that is shown to be a good diagnostic indicator of the state of the detector. The distribution of events found by the analysis is discussed, and it is shown how the number of events vary with the state of the detector.

Abstract:
Highway engineers have addressed the problem of pavement maintenance by developing remaining life assessment methods based on structural analysis of computer simulations of pavements tested in the field by non-destructive testing devices such as the Falling Weight Deflectometer (FWD). However the methodologies followed have been shown to be unable to provide accurate solutions without undue reliance on the knowledge of the expert engineer who conducts the analysis. A knowledge-based system (KBS) is proposed to "inject" engineering knowledge into the conventional techniques. It has been established on a systematic basis and seeks to cover the variety of the issues which may be encountered in such systems. In its prototype form the system consists of three parts: 1. The finite element analytical program ROSTRA-1. 2. A deductive database. 3. A back-analysis subsystem. The analytical program carries out the analysis of the pavements tested in the field. The deductive database holds the properties of a variety of paving materials and establishes the analytical model. The back-analysis subsystem seeks to perform the tasks required for the analysis of the FWD deflection bowl. To build this system, the POPLOG-Prolog computer language operated under VAX/VMS was selected to work in connection with the analytical program. An evaluation procedure was carried out to investigate the performance characteristics of the prototype system. The results indicated that the POPLOG-Prolog development environment is not the ideal tool for such an application. In addition, it appears unlikely that there is any other development tool available which is markedly more effective than that used. However it is felt that similar functions to those required by the POPLOG-Prolog environment, may be implemented using conventional programming. To permit this, a logical design of a KBS to conduct this task is presented.

Abstract:
As of today, large unused potential for biogas production exist within the Swedish agriculturesector. The biogas production within this sector is, however, associated with several problems such as poor energy efficiency and non-profitable systems. This is to some degree due to lack of standardized technical solutions. International Micro BioGas AB (IMB AB) has been aided by KTH since 2014. This project investigates several innovations from IMB AB in regards to biogas production: - A mixing device- A building capturing waste heat from the digesters (building concept)- Insulation of the digester (cover concept)- Small-scale and modular package systems The innovations listed above are evaluated from energy, economic and environmental perspectives by doing a case study on the dairy farm Ogestad close to Gamleby, Sweden. Two cases are considered. In Case 1, the raw biogas is burned in a combined heat and power-unit (CHP) in order to produce electricity. In Case 2, raw biogas is upgraded in a small-scale upgrading unit to vehicle gas standards which is sold to the market. The results show that the mixing device is promising in terms of energy use. It is therefore recommended to move on with testing of the equipment. The cover concept and the building concept show similar performance from energy and environmental standpoints. The building concept is concluded not to be economically viable. The cost reduction by applying a modular concept where one product can be used on different sized farms is significant. However, the needed investment from the company is large. The goal of achieving a modular system is therefore concluded desirable. The subsidy from the Swedish board of agriculture covering 40 % of the investment cost, has a major impact on the profitability of the systems. Without this subsidy, the systems are not viable in terms of economy. In Sweden, the small-scale vehicle gasproduction (Case 2) was concluded the most profitable as well as the best-performing from energy and environmental standpoints.
Inom den svenska jordbrukssektorn finns stor potential för utvidgning av biogasproduktionen. Det finns dock många problem med småskalig biogasproduktion, exempelvis olönsamma och energimässigt ineffektiva system. International Micro BioGas AB (IMB AB) har identifierat att detta till viss del kan bero på bristfälliga tekniska lösningar. Detta då det inte finns någon standardisering av teknik på området. IMB AB har, i samarbete med KTH, sedan 2014 arbetat med olika aspekter av småskalig biogasproduktion. Detta arbete undersöker ett antal innovationer och koncept från IMB AB rörande biogassystem: - En ny metod för omrörning- En byggnad som återvinner värmen från rötkamrarna (byggnadskonceptet)- Ett nytt sätt att isolera rötkamrarna (huvkonceptet)- Småskaliga och modulära paketlösningar Innovationerna och koncepten ovan utvärderas från ett energitekniskt, ekonomiskt och miljömässigt perspektiv genom en fallstudie på mjölkgården Ogestad nära Gamleby i Sverige. Två användningsområden för biogasen analyseras. I Fall 1 (Case 1) bränns rågasen i en kraftvärmeanläggning för att producera elektricitet och värme. I Fall 2 (Case 2) uppgraderas rågasen till fordonsgaskvalitet som sedan säljs till marknaden. Resultaten visar att den nya omrörningsmetoden är lovande ur ett energiperspektiv och enrekommendation är att gå vidare med tekniken och göra experimentella studier. Byggnadskonceptet och huvkonceptet visade likvärdiga resultat ur energitekniskt och miljömässigt perspektiv. Byggnadskonceptet konstaterades vara ineffektivt ur ett ekonomiskt perspektiv. Kostnadsreduceringen som uppnås genom att systemet är modulärt och därmed kan produceras i stor skala till olika gårdsstorlekar, är signifikant. Det krävs dock en stor investering från företagets sida. För samtliga fall är systemens lönsamhet starkt beroende av Jordbruksverkets subvention på 40 % av investeringskostnaden och utan den ökar företagetsinvesteringsbehov drastiskt. Med svenska förutsättningar är småskalig produktion av fordonsgas det mest lönsamma samt mest fördelaktiga ur ett miljö- och energiperspektiv.

Abstract:
L'objectif de ce travail de thèse est le développement d'une méthodologie pour la génération rapide d'architectures flexibles et modulaires pour les systèmes distribués. Cette approche, appelé aussi "prototypage virtuel", est une étape essentielle dans le processus de conception conjointe des systèmes mixtes logiciel/matériel. Les approches de recherche dans ce domaine sont motivées par le besoin urgent de prototypes pour valider la spécification, par la disponibilité des outils et des environnements de synthèse pour les parties logicielles et matérielles. Le prototypage virtuel permet à la fois la manipulation du domaine logiciel ainsi que du domaine matériel. Il prend en entrée une architecture hétérogène composée d'un ensemble de modules distribués issu du découpage matériel/logiciel et génère des descriptions exécutables pour des éléments matériels et logiciels. Ce travail décrit une stratégie de prototypage virtuel pour la co­synthèse (génération des modules matériels et logiciels sur une plate­forme architecturale) et la co­simulation (c'est­à­dire la simulation conjointe de ces deux composants) dans un environnement unifié. Ces travaux définissent également le développement d'un environnement de co­simulation distribué et flexible permettant l'utilisation de différents outils de simulation, de langages, la génération de modèles matériels et logiciels synthésisables et l'ordonnancement des modèles multiprocesseurs sur une architecture monoprocesseur. Cette approche, présentée dans la conférence ED&TC, a obtenu le prix de l'année 1995. Des outils ont été mis en pratique dans l'environnement de conception conjointe Cosmos. Ce travail a aussi fait l'objet d'un transfert de technologie au profit de SGS­Thomson Microelectronics. Les outils développés au cours de cette thèse ont été utilisés pour les projets Européens COMITY (particulièrement utilisé par l'Aérospatiale Missiles à Toulouse et Intracom en Grèce) et CODAC, et par d'autres groupes comme le FZI de l'université de Tübingen et PSA à Paris
The objective of this work is to develop a methodology for the generation of flexible and modular architectures for distributed systems. This approach (also called " virtual prototyping ") is an essential stage in the process of joint design (codesign) of mixed software/hardware systems. Virtual prototyping takes as input a heterogeneous architecture made up of a whole of distributed modules resulting from software/hardware partitioning. It generates executable descriptions for software and hardware elements. Research approaches in this field are justified by the evolution of technology, the urgent need for prototypes to validate the specification, and by the availability of tools and synthesis environments for the design of software and hardware parts. One of the major difficulties of virtual prototyping is that it allows at the same time to handle both, software and hardware. This work describes a strategy of virtual prototyping for the cosynthesis (generation of the modules material and software on an architectural platform) and cosimulation (i. E. The joint simulation of these two kind of components) in a unified environment, the development of a distributed and flexible cosimulation environment allowing the use of several simulation tools and languages, the generation of hardware/software synthesizable models and mono-processor architecture software generation for a set of communicating processes. This approach, presented in the ED&TC conference, got the best paper award in 1995. The tools developed during this thesis were put into practice in the Cosmos codesign environment. One of them was transferred to SGS-Thomson Microelectronics. The tools were also used for the Europeans projects COMITY (particularly used by Aerospace the Missiles in Toulouse and Intracom in Greece) and CODAC, and by other groups like the FZI of the university of Tübingen and PSA in Paris

Since the population of the world is ageing rapidly, how to provide appropriate healthcare to the elderly and disabled people becomes an important issue and draws high attention from medical, academic and industrial fields of the society. The Internet of Things (IoT) drives the evolution of the Internet, and is regarded as a great potential to improve quality of life for the surging number of elderly people significantly. To promote  a more widespread adoption of technologies underlying IoT, trust and security issue must be paid attention to. As Android operating system gains immense popularity nowadays, it is a trend to make use of it for the wider access of IoT utility. This paper presents an intelligent and secured medicine system prototype  based on IoT, and it aims to offer assistance about medicine taking with the support of smart devices as medicine cabinet and Android applications. At the same time, this system allows the users to keep track of the relevant "things" connected to the Internet and protects  the privacy of the user data in transit.

Abstract:
Many new fabrication technologies, from nanotechnology and MEMS to printed organic semiconductors, center on constructing arrays of large numbers of sensors, actuators, or other devices on a single substrate. The utility of such an array could be greatly enhanced if each device could be managed by a programmable controller and all of these controllers could coordinate their actions as a massively-parallel computer. Kentucky Architecture nanocontroller array with very low per controller circuit complexity can provide efficient control of nanotechnology devices. This thesis provides a detailed description of the control hierarchy of a digital system needed to build "nanocontrollers" suitable for controlling millions of devices on a single chip. A Verilog design and FPGA prototype of a nanocontroller system is provided to meet the constraints associated with a massively-parallel programmable controller system.

Directional solvent extraction has been demonstrated as a low temperature, membrane free desalination process. This method dissolves the water into an inexpensive, benign directional solvent, rejects the contaminants, then recovers pure water, and re-uses the solvent. In order to bring this technology closer to real world application, a continuous process prototype for a directional solvent extraction system was developed and tested. Octanoic acid was used as the solvent of choice, and a system capable of producing up to 7 gallons per day of fresh water was constructed. The system was tested to effectively desalinate the feed water, and the total system power was less than 7 kW. The system was constructed and first tested to run fresh water and solvent through it. Fresh water was dissolved in and separated, as expected, from the solvent at a rate of about 2 gpd. Saline water containing 3.5% sodium chloride was then used as feedwater and the desalinated water was recovered at a rate of about 1 gpd with an average salinity of 0.175%. Effective continuous operation of the directional solvent extraction prototype was demonstrated. Certain design improvements to increase efficiency, optimize component sizes, and decrease energy consumption are suggested. The demonstrated system has a wide range of applications, including production of fresh water from the sea, as well as, treatment of produced and flowback water from shale gas and oil extraction.

Design and development of a 1/10 scale prototype of a Full Dimension Continuous Haulage System manufactured by the Long-Airdox Company. The prototype, which will allow development and testing of path-planning and control algorithms for autonomous navigation and operation in underground coal mines, has been completed. The prototype system, though not an identical copy, clones all full-scale model degrees of freedom and functions necessary for navigation. In addition to the physical structure, a microcontroller-based system was developed for providing the necessary low-level motor controls, data gathering and multiple processor communications. High level software running on a laptop PC with the windows operating system is used for analyzing all measurement data, execution of path-planning and control algorithms and issuing the command data.

International Telemetering Conference Proceedings / October 30-November 02, 1989 / Town & Country Hotel & Convention Center, San Diego, California
While the complete process of preparing telemetry data for delivery to NASA's customers requires a number of steps or levels (level 0,1,2...etc.), the initial processing, generally referred to as Level Zero Processing (LZP), poses a real technical challenge for NASA in the 1990s Space Station Freedom era. This challenge is the result of requirements to provide real-time or near real-time LZP products at rates up to 150 Mbps. In addition, increased use of sophisticated data formats places even more demand on NASA's future ground telemetry data systems. A new high speed Level Zero Processing system approach has been proposed for the Space Station Information System. By using a new processing algorithm, the complexity of database management necessary for reconstructing payload data streams has been significantly reduced. This new approach is based on the state-of-art distributed real-time processing and VLSI hardware systems and offers potential processing rates up to 150 Mbits per second (Mbps).

Abstract:
Breast cancer is a major health concern in the United States. Mammography is the gold standard for screening breast cancer and screen-film technology is still widely used in the screening for breast cancer. However, screen-film systems have limited dynamic range and contrasts compared to digital systems, and do not offer integrated image processing capabilities. Recently, digital mammography has seen an upsurge in clinical adoption but current digital mammography systems are limited in terms of their spatial resolution. Therefore, high-resolution digital mammography systems with superior signal-to-noise ratio and contrast characteristics need to be explored. A monolithic, single module high-resolution (39 um) digital x-ray platform (Fairchild Imaging Inc., Milpitas, CA) was developed and characterized for digital mammography. The architecture was extended to a large area (16 x 24-cm) multi-module solid-state imager with variable resolution (39 and 78-um). In addition, a four module (16 x 16-cm) imaging architecture with 78-um pixel was explored for high-resolution contrast enhanced digital mammography for the detection of malignancy-associated angiogenesis. Simulations based on the cascaded linear systems framework were performed in order to characterize the physical properties of the imaging platforms such as the modulation transfer function (MTF), noise power spectra (NPS), and detective quantum efficiency (DQE). Experimental measurements of imager performance was also conducted and compared to model predicted results. Further, perceptual analysis of the prototype imaging platform for digital mammography was performed. Various imaging platforms were successfully developed and investigated to identify essential parameters for high-resolution digital x-ray breast imaging. The single module prototype exhibited physical characteristics that are favorable for digital mammography. Good agreement between model and experimental results were observed demonstrating the utility of such models for further system improvement. The large area 16 x 24-cm prototype demonstrated superior contrast-detail characteristics compared to a clinical FFDM system (100 um pixel) at both 39 and 78-um pixel sizes. Both experimental and theoretical results pointed towards the feasibility of contrast enhanced mammography at mean x-ray glandular dose levels substantially lower than mammography under the conditions investigated. Qualitative analysis of contrast enhanced digital mammography indicated favorable image quality.

Abstract:
In public safety, geography plays a significant role. One of the most important front-line elements of public safety is an efficient emergency transport and care system. The capacity to access and process information rapidly and organize resources where needed can be critically important in an emergency situation. Information about the locality of an event or a disaster is often vital in knowing how to respond. A significant operation in handling emergency situations is the routing of ambulances to incident sites and then to the closest appropriate hospitals. One of the important steps to survival in an emergency is quick response time. The aim of this thesis study is to build an immediate, rapid and efficient emergency medical transport system prototype, called Ambulance Routing Service Application Prototype (ARSAP), to be used in Middle East Technical University (METU) Emergency Service, Ankara, Turkey. In the study, geographical information systems (GIS) technology is used in assisting the development and implementation of an emergency medical service (EMS) response system. In this prototype, while choosing a proper facility, the available quantity of beds, respiratory equipments and doctors in a hospital'
s intensive care room and the best traffic routes to the hospital in hand are also considered. The ARSAP is expected to shorten the commuting time and hence to reduce the damage to the patient to the lowest level and allow the ambulance staff to perform their task better. The results generated using the ARSAP are validated and analyzed by comparing with currently practiced emergency call paths data collected with the help of METU Emergency Service ambulance drivers.

Due to the development of the network technology, Internet plays the most important role. With the growing of e-commerce, WWW has been the part of our regular life. Some behaviors in the Internet are much more popular, like data search, talking, shopping and pay tollage. The effect to people is increasing on using Internet. The change of the behavior of people using Internet not only made a lot of commercial chance but also force some traditional industry made some change to response it. Obviously, it also affects the domain of the product design and fabrication. The goal of this thesis is to discuss the possibility of combining product design and WWW. Generally, “concept design” is in the early level of product design. We believe that it is also the most suitable part of product design levels to combine with WWW. It can support designers the most help by the way of using the rich resources and technology on Internet. This research focuses on the design of the system architecture, distributed object technology, and the virtual prototype model implemented by Java and VRML. A case study of mechanical assembly design will be constructed to demonstrate the feasibility of a client-centered architecture.

Drilling is the most popular metal cutting process in manufacturing industry (e.g., printed circuit board or aircraft assembly). However, it is difficult to achieve high quality drilling and mass production at the same time if relying on manual drilling. Therefore, the development of drill automation technology has become more and more crucial in recent years. This study presents the design and implementation of an automatic drilling system based on the concept of series elastic actuator (SEA). One advantage of using SEA for the current system design is the exemption from installing high cost force sensors for force control implementation. The force based control system has been transformed to a position based control system by adding the elastic components to the driven actuator and the environmental load. A magnetic adhesion module is included into our drilling system so that this system can handle workpiece drilling at different positions or inclined angles. There are two principal issues that should be considered during drilling process. The first one is to avoid the impact force generated at the moment the drill bit makes contact with the workpiece surface. The second one is the requirement of maintaining constant thrust force during the drilling process. To effectively address the issues mentioned above, this research presents a position/force switching control strategy to improve the drilling surface quality and drilling efficiency. Finally, the machined quality of the holes drilled by using different control strategies and drilling conditions are evaluated by measuring the surface roughness of the holes. Based on this drilling performance index, proper drilling conditions of the system can be found and the experiments justify the feasibility of the prototype of our proposed automatic drilling system.

Intelligent Transportation System (ITS) combines high technology and improvement in information systems with the conventional transportation infrastructure. The European designed Radio Data System - Traffic Message Channel (RDS-TMC) is developed to provide traffic information to drivers via broadcast system. The current RDS-TMC systems have some drawbacks, e.g. the maximum message number constraint, one-way directional broadcasting. In this paper, we propose to transmit TMC messages via vehicular ad hoc networks, called VANET-TMC systems. The VANET-TMC systems can not only provide bi-directional communications to interactively update traffic information but also give a scalable and localized services.
