Kiadtikornthaweeyot, Warinthorn. "Onboard computer technology for cubesats". Thesis, University of Southampton, 2015. https://eprints.soton.ac.uk/380017/.

Abstract (sommario):
This thesis addresses the problem of cubesat limitations on transmission power and onboard memory storage. The number of small satellites is continuing to increase. The reduced amount of time and budget required for the development of these satellites has considerable advantages. The short time leads to data becoming available faster than from a larger satellite. Consequently, the communication system is very important to ensure that all data from the cubesat can be transmitted to the receiving station. In this thesis the link budget of a cubesat has been studied to identify the constraints on power and data transmission. As cubesat satellites become more complex, additional constraints and requirements are placed on system components. For more complex missions, greater flexibly of the onboard computer architecture is required to support the mission adaptation or changing specifications of onboard devices. Alternative onboard computer architecture for the next generation of cubesats is presented in this thesis and hybrid onboard computer architecture is proposed. There are many cubesats which have provided remote sensing imagery. An issue is how to store the data onboard and how to transmit these data with limited power. A solution is to reduce the size of the original image by pre-image processing. The potential for using image compression and defining the region of interest to decrease the original satellite image size has been examined in this research. Three approaches are studied and described in the context of the region of interest technique. There is image segmentation based on edge, histogram and texture detection. The presented evaluation is focused on the detection of the land part of the image that contains dynamic information and rejecting the ocean where there is less interest. The technique, however, is equally applicable for any region of interest that can be characterised and this is illustrated by considering some examples. The proposed adaptive image compression system is made up of two parts. The first part consists of the identification of the region of interest and the second part the image compression of this region of interest. The accuracy of the proposed system has been examined by comparing the number of different pixels between the proposed automatic region of interest system and the manual detection of the region of interest. Morphological methods are the main technique that has been used in the system. The morphology structure element has different shapes and size and it is necessary to understand how the shape and size of the structure elements affects the proposed system. A study of structure element has been conducted. In the real implementation of the proposed system on a cubesat, additional power would be required. To quantify this increase, a particular proposed system based on edge segmentation for region of interest automatic detection has been studied. The potential for using the proposed image compression to detect the region of interest and image compression was examined using a standard microcontroller. The result shows that the proposed system could be used on a cubesat satellite with reasonable additional power and mass.

Pinder, Charlie. "Targeting the automatic : nonconscious behaviour change using technology". Thesis, University of Birmingham, 2018. http://etheses.bham.ac.uk//id/eprint/8539/.

Testo completo
Abstract (sommario):
Digital interventions have great potential to support people to change their behaviour. However, most interventions focus on strategies that target limited conscious resources, reducing their potential impact. We outline how these may fail in the longer-term due to issues with theory, users and technology. We propose an alternative: the direct targeting of nonconscious processes to achieve behaviour change. We synthesise Dual Process Theory, modern habit theory and Goal Setting Theory, which together model how users form and break nonconscious behaviours, into an explanatory framework to explore nonconscious behaviour change interventions. We explore the theoretical and practical implications of this approach, and apply it to a series of empirical studies. The studies explore nonconscious-targeting interventions across a continuum of conscious attention required at the point of behavioural action, from high (just-in-time reminders within Implementation Intentions) to medium (training paradigms within cognitive bias modification) to low (subliminal priming). The findings show that these single-nonconscious-target interventions have mixed results in in-the-wild and semi-controlled conditions. We conclude by outlining how interventions might strategically deploy multiple interventions that target the nonconscious at differing levels of conscious attention, and by identifying promising avenues of future research.

Abstract (sommario):
This research study presents a Hypothesised Model, developed on the basis of the Unified Theory of Acceptance and Use of Technology (UTAUT). Its aim is to evaluate innovative Health Information Technology (HIT) at the early stages of projects. It is contended that this practice would support system developers at the design and implementation phases, and reduce the risk of underutilisation or rejection. The performance of the model was tested in three studies within the Clinical Trial Management Systems framework. The Hypothesised Model approaches Behavioural Intention from a socio-technical point of view, taking into consideration the complexity and need of HIT to achieve joint optimisation. Moreover, it simplifies and extends UTAUT so that it may fit soundly within the healthcare context. Hence, it excludes the moderators and adds three core constructs, including: System-Specific Features, Technology Anxiety, and Adaptation Timeline. However, the model is easily adjustable to fit specific situations, especially given that this research study posits the non-existence of a single model that suits all situations. This approach appears to have improved the final outcome and outperformed the use of generic models within the healthcare context. The total explained variance reported from the three studies is: (76%), (86%), and (87%) respectively.

Cooper, Simon. "DISE : a game technology-based digital interactive storytelling framework". Thesis, Liverpool John Moores University, 2011. http://researchonline.ljmu.ac.uk/6101/.

Abstract (sommario):
This thesis details the design and implementation of an Interactive Storytelling Framework. Using software engineering methodology and framework development methods, we aim to design a full Interactive Storytelling system involving a story manager, a character engine, an action engine, a planner, a 3D game engine and a set of editors for story data, world environment modelling and real-time character animation. The framework is described in detail and specified to meet the requirement of bringing a more dynamic real-time interactive story experience to the medium of computer games. Its core concepts borrow from work done in the fields of narrative theory, software engineering, computer games technology, HCI, 3D character animation and artificial intelligence. The contributions of our research and the novelties lie in the data design of the story which allows a modular approach to building reusable resources such as actions, objects, animated characters and whole story 'levels'; a switchable story planner and re-planning system implementation, allowing many planners, heuristics and schedulers that are compatible with PDDL (the "Planning Domain Definition Language") to be easily integrated with minor changes to the main classes; a 3D game engine and framework for web launched or in browser deployment of the finished product; and a user friendly story and world/environment editor; so story authors do not need advanced knowledge of coding PDDL syntax, games programming or 3D modelling to design and author a basic story. As far as we know our Interactive Storytelling Framework is the only one to include a full 3D cross-platform game engine, procedural and manual modelling tools, a story -editor and customisable planner in one complete integrated solution. The finished interactive storytelling applications are presented as computer games designed to be a real-time 3D first person experience, with the player as a main story character in a world where every context filtered action displayed is executable and the player's choices make a difference to the outcome of the story, whilst still allowing the authors high level constraints to progress the narrative along their desired path(s).

Abstract (sommario):

University lab environments are handled differently than corporate, government, and commercial Information Technology (IT) environments. While all environments have the common issues of scalability and cross-platform interoperability, educational lab environments must additionally handle student permissions, student files, student printing, and special education labs. The emphasis is on uniformity across lab machines for a uniform course curriculum.

This thesis construes how a specific set of Computer Science labs are maintained. It describes how documentation is maintained, how the lab infrastructure is setup, how the technicians managing the lab build master lab images, how all of the workstations in the lab are cloned, and how a portion of the maintenance is handled. Additionally, this paper also describes some of the specialty labs provided for courses with functional topics.

Abstract (sommario):
The Israeli Ministry of Education launched the "Tomorrow 98" programme in 1994 to integrate computer-technology into the educational system. Training the teachers for this change was one of the main goals of the programme. This study examined the integration of computer-based technology of 167 ESL teachers who had participated in the course "Integrating Computers into the English Class" organised since 1994 by the Israeli Ministry of Education. This two phased study included a questionnaire sent to all the ESL teachers who participated in the course and in-depth interviews conducted with five teachers (three users and two non- users of computer technology in their teaching) and five leading figures in their schools (three computer coordinators who work in the users' schools and two school principals in whose schools the two non-users teach). The analysis of the findings shows that 70 per cent of the teachers who participated in the course integrate computer technology in their teaching. A majority of these teachers have changed their teaching methods both in the computer environment and the regular classroom. They enjoy working in the computer room more than in the normal classroom and believe that their learners feel the same. The teachers state that their main obstacles are lack of time and access. Technical problems ceased to intimidate them as they have learnt to overcome them with the aid of their learners or peers. Of the 30 per cent who do not use computers in teaching, 93 per cent use computers to prepare their lessons and worksheets. The main reason they do not integrate computers in their teaching is lack of access to computers in school. The study shows that school principals and school cultures have a distinct influence on the success or failure of computer integration in their schools. Collegial school management and supportive school culture encourage teachers to use computers in their teaching and to experiment new teaching methods. It is the hope of the researcher that this study will help teachers, principals, course developers, and other professionals working to integrate technology into instructional settings to understand the issues which accompany this process and lead it to success.

Liu, Peter. "Applying Expert System Technology To Enhance Computer Performance". NSUWorks, 1993. http://nsuworks.nova.edu/gscis_etd/678.

Testo completo
Abstract (sommario):
Computer performance has become increasingly important at modern computer installations. At the same time, performance analysts have shown a strong interest in using expert system technology to meet these new demands. Because of the importance of the system sort product in improving overall system performance, a prototype expert system (KBSORT) was developed. When embedded in the system sort utility, KBSORT optimizes the CPU time performance of the sort applications generated by the system utility. A thorough search of the available literature revealed that no work had yet been done on applying expert system technology to enhancing sort performance. Because the research for this study is a first attempt in this area, a rigorous twelve step procedure was followed in developing the KBSORT prototype. The steps included formulating test cases, researching sort performance enhancement techniques, interviewing experts on sort performance, developing the rules for the expert system, embedding the prototype in the sort utility, and running the sort utility to study the difference in CPU time performance when the expert system was in use. Interviews with sort performance experts revealed that the expert system had to optimize in three areas. It had to choose (1) the best sorting algorithm for the current circumstances, (2) the optimal amount of core for the particular sort, and (3) the proper sort work allocation on the input/output devices available while taking into account the current level of contention for those devices. The results of this study support the original hypothesis that the use of a sort utility with an embedded expert system designed to improve CPU time performance generates applications that run more efficiently than sort applications generated by a sort utility without such an embedded expert system.

Abstract (sommario):
The research is based on fieldwork in the Johannesburg East District where fifteen teachers from different schools participated. The teachers were from a variety of backgrounds in teaching the subject. Each of the teachers voluntarily completed an open-ended questionnaire that was based on their own interpretation of the setting of formal assessment tests or examinations. Document analysis was performed on the preliminary theory examinations that were set by the teachers using an adapted form of Krathwohl‟s two-dimensional taxonomy which was made specific for CAT. The teachers were requested to supply an example of a taxonomy which they themselves had used when analyzing the preliminary theory examination according to cognitive levels. The research findings were derived from the responses to the questionnaires that indicated the teachers‟ opinions about the setting of formal assessments as well as from formal test papers the teachers provided. The vast majority of the participant teachers used examinations set by others, either those purchased from publishers or publically accessible past papers downloaded from the internet with minimal change. It appears that the teachers did not use any taxonomy of cognitive levels even when they designed their own question papers. The cognitive level addressed was primarily memorisation and recall. The teachers were more concerned about the format and style of their examination papers than the cognitive levels the papers addressed. Additionally the overwhelming majority did not believe that training in assessment design would be of value to them (as experienced teachers), although some suggested that such training may be useful for beginning teachers. This suggests that further research on the teachers‟ experiences in using taxonomies when setting formal assessments, as well as potential in-service training interventions that address their knowledge of cognitive levels and appropriate assessments is needed.

Abstract (sommario):
Technology is often presented as a neutral tool to be used when and where appropriate to perform work more efficiently and improve the quality of life. This dissertation explores the possibility that computers are distributed as though they were value-laden objects rather than neutral tools. This is done by focusing on the similarity between computers and income, because income is also distributed by organizations and is generally valued positively. The literature on organizational symbols is reviewed and evidence of the value attached to computers is presented. Previous research on income inequality is discussed focusing on factors empirically associated with income and on factors influencing the allocation of valued goods within a group. Earlier work on individual wage allocation and on the determinants of wage inequality within work groups is partially replicated and extended to the area of computer resources. Hypotheses regarding the distribution of income and computers are developed at both the individual and group level and the possibility that computer terminals act as value-laden objects is explored by comparing their distribution to that of income in white-collar work groups when computer use is statistically controlled. At the individual level, computer terminals and income shared many of the same correlates and predictors. For the sample as a whole, computers and income were slightly positively correlated and previous findings that characteristics of work and of individuals are related to income were replicated. The same set of predictors was also related to having one's own computer terminal, providing evidence that computer resources could act as symbols of status. Exploratory analyses indicated that the pattern of results differed by the organizational function of the work group and by job classification. Though use was consistently related to having one's own terminal, it was never the only factor involved. Group-level evidence of symbolic value was equivocal; previous findings regarding the distribution of income were not replicated and the pattern of relationships for computers was different from that for income. Implications of the symbolic value of computers for managers and directions for future research were described.

Alsalamah, Hessah. "Supporting integrated care pathways with workflow technology". Thesis, Cardiff University, 2012. http://orca.cf.ac.uk/28816/.

Testo completo
Abstract (sommario):
Modern healthcare has moved to a focus on providing patient centric care rather than disease centred care. This new approach is provided by a unique care team which is formed to treat a patient. At the start of the treatment, the care team decide on the treatment pathway for the patient. This is a series of treatment stages where at the end of each stage, the care team use the patient’s current condition to decide whether the treatment moves to the next stage, continues in the treatment stage, or moves to an unanticipated stage. The initial treatment pathway for each patient is based on the clinical guidelines in an Integrated Care Pathway (ICP) [1] modified to suit the patient state. This research mapped a patient ICP decided by the healthcare providers into a Workflow Management System (WFMS) [2]. The clinical guidelines reflect the patient-centric flow to create an IT system supporting the care team. In the initial stage of the research the IT development team at Velindre Hospital identified that team communication and care coordination were obstacles hindering the implementation of a patient-centric delivery model. This was investigated to determine the causes, which were identified as difficulty in accessing the medical information held in dispersed legacy systems. Moreover, a major constraint in the domain is the need to keep legacy systems in operation and so there is a need to investigate approaches to enhance their functionalities. These information systems cannot be changed across all healthcare organisations and their complete autonomy needs to be retained as they are in constant use at the sites. Using workflow technology, an independent application representing an ICP was implemented. This was used to construct an independent layer in the software architecture to interact with legacy Clinical Information Systems (CISs) and so evolve their offered functionalities to support the teams. This was used to build a Virtual Organisation (VO) [3, 4] around a patient which facilitates patient-centric care. Moreover, the VO virtually integrates the data from legacy systems and ensures its availability (as needed) at the different treatment stages along the care pathway. Implications of the proposal include: formalising the treatment process, filtering and gathering the patient’s information, ensuring care continuity, and pro-acting to change. Evaluation of the proposal involved three stages; First, usefulness evaluation by the healthcare providers representing the users; Second, setup evaluation by developers of CISs; and Finally, technical evaluation by the community of the technology. The evaluation proved; the healthcare providers’ need for an adaptive and a proactive system, the possibility of adopting the proposed system, and the novelty and innovation of the proposed approach. The research proposes a patient-centric system achieved by creating a version of an ICP in the system for each patient. It also provides focussed support for team communication and care coordination, by identifying the treatment stages and providing the care team requirements at each stage. It utilises the data within the legacy system to be proactive. Moreover, it makes these required data for the actions available from the running legacy system which is required for patient-centred care. In the future the worth could be extended by mapping other ICPs into the system. This work has been published in four full papers. It found acceptance in the health informatics community [5, 6, 7] as well as the BPM community [8, 9]. It is also the winner of the 2011 “Global Award of Excellence in Adaptive Case Management (ACM)” in “Medical and Healthcare” [10] of the Workflow Management Coalition (WFMC) [11].

A Design Workbench has been built for Napier88 [MBC+94] as part of the natural progression towards developing better product systems and improving software construction tools. The system includes a Metamodeller (enabling users to specify the data and process models they prefer), a Model Builder which supports multiple coexisting models and a Target System Generator. Experience using the Workbench has shown that it is easy to use, increases productivity, improves programming standards and facilitates code sharing. This thesis demonstrates the benefits of orthogonal persistence for Computer-Aided Software Engineering by describing an initial design environment and its subsequent extension to include support for multiple co-existing models.

Testo completo
Abstract (sommario):
Social and organisation theorists have become increasingly interested in studying information and communication technologies over the last two decades. This thesis examines how information and communication technologies are organised, and what is organised by information and communication technologies. The thesis contributes to the interest in detailed studies of information and communication technology through an analysis of the implementation and deployment of a mobile data system-the Vehicle Mounted Data System (VMDS)-by firefighters, fire crews and officers at a United Kingdom fire brigade. This thesis examines what becomes of the Vehicle Mounted Data System when it is introduced into a UK fire brigade. This includes an exposition of how recurring issues including the boundaries of the brigade, what is meant by standardisation and risk, what counts as information, and what is understood by devolved incident management is reordered as the VMDS becomes a constitutive part of the problematic fire service provision. The VMDS is bound up with reality constituting effects and this means that what is meant by technology and organisation becomes an important topic of scholarly study. This thesis develops a non-essentialist ontology of technology and organisation-an ontological turn in organisation theory. It is argued that the VMDS is a relational effect that is aligned with existing boundaries and assumptions at Hereford and Worcester Fire Brigade, that the VMDS is a multiple object that is a mutable mobile and is deployed not only to manage safety at incidents but also for managing performance and organisational flexibility, and that the instabilities of the VMDS are responded to ambivalently by various actors as they are enrolled in the collective upkeep of the VMDS. In analysing the Vehicle Mounted Data System a range of analytical resources are drawn upon, including, most significantly, actor-network theory, but also the writings of Deleuze and Guattari. The thesis concludes with a discussion of the politics of theory and suggests that researchers would remain faithful to their intellectual tradition and a sense of critical and creative purpose if they engaged with and helped to construct the heterogeneous ways in which technological devices such as the Vehicle Mounted Data System transform what organisation theorists understand by organisation.

Johansson, Björn. "Multiscale Curvature Detection in Computer Vision". Licentiate thesis, Linköping University, Linköping University, Computer Vision, 2001. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-54966.

Testo completo
Abstract (sommario):

This thesis presents a new method for detection of complex curvatures such as corners, circles, and star patterns. The method is based on a second degree local polynomial model applied to a local orientation description in double angle representation. The theory of rotational symmetries is used to compute curvature responses from the parameters of the polynomial model. The responses are made more selective using a scheme of inhibition between different symmetry models. These symmetries can serve as feature points at a high abstraction level for use in hierarchical matching structures for 3D estimation, object recognition, image database search, etc.

A very efficient approximative algorithm for single and multiscale polynomial expansion is developed, which is used for detection of the complex curvatures in one or several scales. The algorithm is based on the simple observation that polynomial functions multiplied with a Gaussian function can be described in terms of partial derivatives of the Gaussian. The approximative polynomial expansion algorithm is evaluated in an experiment to estimate local orientation on 3D data, and the performance is comparable to previously tested algorithms which are more computationally expensive.

The curvature algorithm is demonstrated on natural images and in an object recognition experiment. Phase histograms based on the curvature features are developed and shown to be useful as an alternative compact image representation.

The importance of curvature is furthermore motivated by reviewing examples from biological and perceptual studies. The usefulness of local orientation information to detect curvature is also motivated by an experiment about learning a corner detector.

Testo completo
Abstract (sommario):
This thesis concerns the estimation and description of curvature for computer vision applications. Different types of multi-dimensional data are considered: images (2D); volumes (3D); time sequences of images (3D); and time sequences of volumes (4D). The methods are based on local Fourier domain models and use local operations such as filtering. A hierarchical approach is used. Firstly, the local orientation is estimated and represented with a vector field equivalent description. Secondly, the local curvature is estimated from the orientation description. The curvature algorithms are closely related to the orientation estimation algorithms and the methods as a whole give a unified approach to the estimation and description of orientation and curvature. In addition, the methodology avoids thresholding and premature decision making. Results on both synthetic and real world data are presented to illustrate the algorithms performance with respect to accuracy and noise insensitivity. Examples illustrating the use of the curvature estimates for tasks such as image enhancement are also included.

Teterin, Vitaly. "Optimized network dimensioning and planning for WiMAX technology". Thesis, Cardiff University, 2012. http://orca.cf.ac.uk/18595/.

Testo completo
Abstract (sommario):
In order to meet demands in mobile broadband and to bridge the digital divide a new technology, namely WiMAX, was introduced in 2004. However, in order to increase the financial return on the investment inWiMAX, service operators need to make every effort in designing and deploying the most cost-effective networks. This thesis presents a novel dimensioning technique for WiMAX technology which takes the dimensioning problem to a new level and produces more accurate results in comparison to the traditional methods. Furthermore, a novel decomposed optimization framework for the WiMAX network planning is introduced which subdivides the overall problem into three distinct stages consisting of the network dimensioning stage which besides the primary task of evaluating the financial requirements produces a good starting network solution for the subsequent stages (Stage 1), initial sectorization and configuration of the network (Stage 2) and final network configuration (Stage 3). The proposed framework also solves two fundamental problems, which are cell planning and frequency planning, simultaneously. The feasibility of the final network solutions are then evaluated by OPNET simulator.

Abstract (sommario):
Perceptually-seductive technology (PST) is introduced as a way of designing IT environments that can help support everyday creativity. This is done in part by using sensory stimulation, seclusion and other perceptual components to seduce an individual towards creative insights that would not occur on the basis of conceptual thought alone. Everyday creativity is characterised as the combination of novel solutions in addressing everyday problems, and learning, indicating endurance over time. Everyday creativity is sometimes referred to as personal creativity, since it concerns what is novel to an individual, not to society as a whole. As in exceptional or historical creativity, in everyday creativity the novelty arises from the individual concerned, not from outside. Literature reviews of learning and memory, emotion and creativity set the scene and provide the basis for introducing PST. The relation of the individual to the technology, and with the world through the technology, is also considered. A model of the design space for PST is proposed and related to a proposed view of the creative process. It is suggested that to stimulate and support the creative process, IT environments should encourage both presence (perceptual or experiential mental activity) and absence (conceptual or reflective mental activity), which are seen as end points of a continuum comprising the Focus dimension. Similarly, the importance of both conscious and unconscious activity (the Sensus dimension) is emphasised, as is the role of emotion in mediating the balance between the two. The Locus dimension refers to the real-virtual distinction. In PST, virtual realisations are used to represent real world things and events and in so doing support the memorisation and reflection that are essential to everyday creativity. Four different examples of designing and implementing PST are presented. The first is a media production within a novel environment called the Interactive Tent, and is a demonstration and validation of theoretical ideas behind the PST concept. Three educational PST environments and their formative evaluations are then presented. These are first steps towards designing PST for particular kinds of application, in this case as environments for memorisation. Taken together, these examples lead to design recommendations and suggestions for future work, including the application of PST in education, stress management and for the elderly and disabled.

Abstract (sommario):
While information technology has rapidly changed work in the United States in the past 50 years, some businesses and industries have been slow to adopt new technologies. Healthcare is one industry that has lagged behind in information technology investment for a variety of reasons. Recent federal initiatives to encourage IT adoption in the healthcare industry provide an ideal context to study factors that influence technology acceptance. Data from 261 practicing pediatricians were collected to evaluate an extended Technology Acceptance Model. Results indicated that individual (i.e., perceived usefulness, perceived ease of use), organizational (i.e., subjective norm), and device (i.e., compatibility, reliability) characteristics collectively influence pediatricians' intention to adopt tablet computers in their medical practice. Theoretical and practical implications are discussed. Future research should examine additional variables that influence information technology adoption in organizations.

Abstract (sommario):
The focus of this investigation has been to obtain new knowledge regarding the importance of word processing software to the profession of physical therapy. Presently there are limitations in the knowledge base concerning the training, use of, and understanding of individual attitudes toward word processing software for physical therapists in patient care documentation. The limitations inherent in existing word processing software for physical therapists frequently requires each organization adapt patient care documentation methodology to comply with generic manufacturer software specifications. An Equivalent Groups Posttest-Only Design was utilized to measure the abilities of thirty-six physical therapists to use word processing technology to accurately document patient care activities following a period of training. Eighteen therapists were randomly assigned membership to the control and experimental groups (n=36). Two types of training methodology were employed. Traditional lecture was provided to each member of the control group on an individual basis regarding use of the word processing software WordPerfect 5.1. A fifty minute video tape presentation produced by the LearnKey Corporation introducing the software WordPerfect 5.1 was presented on an individual basis to each member of the experimental group. Following each method of training, members of the experimental and control groups were asked to type a prepared SOAP note using the WordPerfect software. Upon completing the typing of the SOAP note, each therapist was requested to print a copy of the document from the WordPerfect software program. Attitude surveys were provided to members of each group immediately following the training period to ascertain therapist perceptions concerning the use of computerized patient care documentation. The attitude survey was presented again one week later to each participant in the control and experimental groups. The results of the study indicated no significant differences in performance between the control (lecture) group and the experimental (video) group regarding the time required to complete the typing task and the number of errors committed at a .05 level of significance. An attitude survey investigated therapist perceptions toward the computerized documentation system in six key job performance areas. Results indicated that therapists were generally positive in their attitudes concerning the computerized documentation system. Responses to the attitude statements were most often in agreement with the use of the computerized documentation system in the department of physical therapy. The results of this investigation provides valuable information about training methodologies to be used for physical therapists in computer training. In order to achieve desired learning outcomes, training methodology must focus upon six key job elements and upon end user acceptance of the computerized documentation system.

Abstract (sommario):
This thesis reports on research underpinning the design of a canine-centred dog-to-human communication technology, specifically an emergency alarm system that enables trained assistance dogs to call for help on behalf of their owners. Thousands of vulnerable people worldwide living with conditions such as epilepsy, diabetes or limited mobility, rely on assistance dogs to help them in their daily lives. When, for various reason, the human becomes incapacitated, such as when they are experiencing an epileptic seizure, have fallen, or have gone into a hypoglycaemic coma, it is down to their dog to take action to resolve the situation. Interactive technology can provide an assistance dog with the means to raise the alarm and summon help, but in order to enable them to independently and successfully engage with an alarm, it is critical that they are able to make sense of when and how to use the device to increase their chances of successful interaction. Thus, the research presented here aimed to understand the factors that might influence the dog’s ability to successfully interact with the system we undertook to design. Our initial design was informed by various biological, cognitive, and ergonomic considerations of dogs. We then elicited specific requirements for a canine emergency communication system by observing training practices to learn how trainers communicate with the dogs; interviewing human-dog partnerships to understand their needs; and engaged in rapid prototyping sessions with the dogs to identify their preferences. Using these requirements, we developed several high-fidelity prototypes, which we tested with assistance dog users and their handlers, to identify which design features might best facilitate the dog’s interaction with the device, and in turn enable the design of the training process through which the dogs learn to use the device as independent agents. This led to the practical observation that for many assistance dogs, using an interface that allows them to bite an attachment with their mouth and tug it until it detaches was easy for them to learn to use. We found that when designing technology for assistance dogs, researchers need to consider to what extent the dogs might be expected to drive the interaction and that researchers need to design not only to support the interaction itself but also to facilitate the training process that will eventually lead to the dogs being able to interact with the technology.

Abstract (sommario):
With audit IT technology and data analytics changing at a quick pace, it's imperative that the industry adapts. The motivation for this paper stems from the accounting world and the Big 4 audit firms changing their demands on the profession. I conducted a three-cell-between-subjects experiment using 76 participants through Amazon Mechanical Turk regarding a hypothetical class action lawsuit against auditors for an undetected misstatement. The three conditions included a No IT available, IT available but not used, and IT available and used. My two hypotheses center from the Lowe et al. (2001) paper and how if IT during an audit fails, juries will have lower judgement and competence of the auditor. This paper studied the effect of computer-assisted audits on damage awards in auditor litigation based on evaluative judgments of auditor effort. Following the case, participants answered a series of questions to capture bias and feelings about the auditors. The results supported prior research of the link between evaluative judgments and damage assessments, but did not find the primary, novel hypotheses to be significant. The limitations of this study were the use of MTurk instead of a real jury and the potential bias that people have on the accounting profession.

Abstract (sommario):
Computer aided design and manufacturing (CAD/CAM) has been a focal research area for the manufacturing industry. Genuine CAD/CAM integration is necessary to make products of higher quality with lower cost and shorter lead times. Although CAD and CAM have been extensively used in industry, effective CAD/CAM integration has not been implemented. The major obstacles of CAD/CAM integration are the representation of design and process knowledge and the adaptive ability of computer aided process planning (CAPP). This research is aimed to develop a feature-based CAD/CAM integration methodology. Artificial intelligent techniques such as neural networks, heuristic algorithms, genetic algorithms and fuzzy logics are used to tackle problems. The activities considered include: 1) Component design based on a number of standard feature classes with validity check. A feature classification for machining application is defined adopting ISO 10303-STEP AP224 from a multi-viewpoint of design and manufacture. 2) Search of interacting features and identification of features relationships. A heuristic algorithm has been proposed in order to resolve interacting features. The algorithm analyses the interacting entity between each feature pair, making the process simpler and more efficient. 3) Recognition of new features formed by interacting features. A novel neural network-based technique for feature recognition has been designed, which solves the problems of ambiguity and overlaps. 4) Production of a feature based model for the component. 5) Generation of a suitable process plan covering selection of machining operations, grouping of machining operations and process sequencing. A hybrid feature-based CAPP has been developed using neural network, genetic algorithm and fuzzy evaluating techniques.

Abstract (sommario):
The purpose of this study was to investigate and analyze the preparation of Family and Consumer Sciences (FACS) preservice teachers to teach FACS content using computer technology, a study that had not previously been undertaken. The focus of the study was FACS methods classes and activities, as reported by FACS teacher educators. A survey instrument was developed to determine how computer technology is incorporated into, modeled by the teacher, and required of students in FACS methods courses. The support FACS teacher educators receive from their college or university for teaching with technology, teacher educators' perceived computer skill and comfort levels, and importance placed by teacher educators on technology in secondary and college methods courses were also investigated. Respondents were asked their knowledge of the International Society for Technology in Education technology standards for teachers and their perceptions of preservice students' abilities to meet those standards. The survey was prepared in both printed/mailed and on-line formats to investigate the reliability of using the Internet to conduct survey research with this population. The survey was sent to 208 teacher educators nationwide and information was obtained from 86 respondents for a 41% response rate. Eleven research questions were answered. FACS teacher educators felt the inclusion of computer technology in both secondary classrooms and their own classrooms was important. While the majority reported average computer skills, they expressed confidence in their ability to teach and demonstrate technology in the classroom. FACS teacher educators were not aware of the ISTE standards but still rated their preservice students high on most standards. Four hypotheses were tested. No differences were found in reported preservice student computer technology abilities and characteristics of the college or university, FACS department, or teacher educator characteristics. There were no differences in responses and characteristics of teacher educators who completed the survey in the print/mailed format and those completing it on-line. Statistically significant differences were found in response rates for printed/mailed versus on-line surveys. FACS teacher educators were more likely to return surveys they received through the mail than complete surveys available on-line. Implications for teacher educators, administrators, and professional organizations are drawn.

Abstract (sommario):
The purpose of this research is to develop a deep understanding of Utah State University teacher educators' perceptions and lived experience with computer technology integration. Ten methods course instructors in secondary education participated. Data were collected using the phenomenological research method: (1) conducting one-on-one in-depth interviews, (2) classroom observations of the four participants, and (3) examining artifacts, such as syllabi and presentation evaluation forms used by the participants. The findings of this research show that the subjects regard computer technology as a powerful instructional tool. They also realize it is important to prepare preservice teachers with computer technology for their future careers. The study analyzes the positive and negative aspects of using computer technology in teaching and personal experiences, and how these influence the participants' computer technology integration. The results indicate four types of computer technology integration among the teacher educators: (1) Advanced Users, (2) Technical Users, (3) Reluctant Users, and (4) Resisters, as well as some advantages and disadvantages of using computer technology in educational settings. Based on the findings of the research, some strategies are suggested to improve the teacher educators' computer technology integration at Utah State University. These suggestions include aspects such as amending training procedures and building a supportive environment in the teacher educators' professional development. Future research perspectives are also proposed at the end of the dissertation.

Abstract (sommario):
[Abstract]: Advances in computer technology and communication technology have been revolutionary during the latter half of the last century. During which, computer technology has transformed the world from the industrial age to the information age. Computer technology by its very nature is a new and intriguing phenomenon to work with. In contrast, nursing by its very nature is an older and most trusted profession to be part of. Uncovering the secrets of combining this media and that profession then became the challenge for the study. The foundations for the study are set within the qualitative model of phenomenology, where the methods are based on the work of van Manen (1997). This framework was used to explore a deeper understanding of the nursing experience with computer technology in the hospital ward. The objectives of the study were primarily to understand computer technology within the social context of nursing and secondly, other objectives were to explore the dynamics, between computer technology and the culture of nursing. Discussion was invited on the positive and negative influences of computer technology as experienced by these nurses.This was achieved by working with nurses in a variety of ward settings including a rural base hospital, as they participated in a series of in-depth, unstructured interviews. The data they provided reflects that computer technology has the potential to impact on the structure and delivery of healthcare, challenge the traditional roles and scope of practice, alter the existing boundaries and relationships and reinvent the clinical environment of nursing.

Abstract (sommario):

This thesis investigates the impact of gamification on student motivation and learning in several introductory computer science educational activities. The use of game design techniques in education offers the potential to make learning more motivating and more enjoyable for students. However, the design, implementation, and evaluation of game elements that actually realize this promise remains a largely unmet challenge. This research examines whether the introduction of game elements into curriculum positively impacts student motivation and intended learning outcomes for entry-level computer science education in four settings that apply similar game design techniques in different introductory computer science educational settings. The results of these studies are evaluated using mixed methods to compare the effects of game elements on student motivation and learning in both formal and non-formal learning environments.

Abstract (sommario):
The integration of self-assembled monolayer (SAM) into microelectromechanical system (MEMS) devices is introduced in Chapter 1. Chapter 2 is concerned with the specific immobilization of NeutrAvidin on pure and mixed SAMs of biotinylated tri(ethylene glycol) undecanethiol (BUT, biotin containing sensor element for Neutravidin) and tetra(ethylene glycol) (TEG, spacer) which were deposited on Au surfaces. Contact angle, ellipsometry and XPS were used to characterize the composition of these SAMs. SPR and QCM were used to study the adsorption behavior of NeutrAvidin to the pure and mixed SAMs. Chapter 3 describes the optimum conditions in details of how to obtain the monolayer of 11-amino-1-undecanethiol hydrochloride (Alk-amine) and 4-aminothiophenol (Ar-amine) SAM, which were deposited on an Au surface by using an ethanolic solution of Triethylamine (TEA) and how to reduce the contamination which are combined with the deposition of the two amines. Finally, ellipsometry, contact angle and XPS were used to characterise the monolayer of two amine SAMs. Chapter 4 describes the optimum conditions of gold nanoparticles (G-NPs) deposition on a monolayer of Alk and Ar-amine terminated SAMs, which were described in chapter 3, at different pHs. AFM and QCM confirm that the optimum deposition of G-NPs was at pH 5 for the two amine SAMs and the deposition on Alk-amine SAM is much higher than on Ar-amine SAM. Thus, Alk-amine SAM was chosen for chemically modifying the surface of a micro paddle. After the modification the paddle was used to detect the deposited mass of G-NPs and SEM was used to confirm dispersity of the monolayer of G-NPs.

Abstract (sommario):

This thesis presents a number of methods to estimate 3D structures with a single translating camera. The camera is assumed to be calibrated and to have a known translation and rotation.

Applications for aircraft altitude estimation and ground structure estimation ahead of the aircraft are discussed. The idea is to mount a camera on the aircraft and use the motion estimates obtained in the inertia navigation system. One reason for this arrangement is to make the aircraft more passive, in comparison to conventional radar based altitude estimation.

Two groups of methods are considered, optical flow based and region tracking based. Both groups have advantages and drawbacks.

Two methods to estimate the optical flow are presented. The accuracy of the estimated ground structure is increased by varying the temporal distance between the frames used in the optical flow estimation algorithms.

Four region tracking algorithms are presented. Two of them use canonical correlation and the other two are based on sum of squared difference and complex correlation respectively.

The depth estimates are then temporally filtered using weighted least squares or a Kalman filter.

A simple estimation of the computational complexity and memory requirements for the algorithms is presented to aid estimation of the hardware requirements.

Tests on real flight sequences are performed, showing that the aircraft altitude can be estimated with a good accuracy.
