Full textAbstract:
Electronic word-of-mouth (eWOM) has increasingly become an important topic in marketing and consumer research. However, theory construction and methodology development in this area are still in their infancy. This leaves some basic and important questions unanswered including whether eWOM communication is effective, what roles are played by different communication cues, and how valuable information from text reviews can be generated. This study intends to answer these fundamental questions.Based on the Brunswik's Len Model, this study developed the Process Model of eWOM Communication. It extends the Brunswik's Lens Model in several important ways and provides a systematic tool to examine the effectiveness of eWOM communication processes. Furthermore, a simplified model of eWOM communication was developed to test the validity of automatic text analysis as a promising tool in studying eWOM communication.Two focus group interviews and a throughout literature review were conducted first to identify the communication cues employed by eWOM partners. Then, two web-based self-administered surveys were carried out to collect data from both eWOM senders and readers. Last, the data from both eWOM senders and readers were matched, forming a final dataset with 90 reviews. Correlations, regressions, and path analyses were employed to evaluate the models and test the hypotheses.Results showed that eWOM communication is effective, and the relative strength of information flow varies in different eWOM communication links when communicating different types of information.This study identified a list of eWOM communication cues and found that consumers employ different cues in communicating different types of information. EWOM readers' inference structure in decoding may not exactly mirror eWOM senders' encoding structure. Moreover, communication cues especially verbal cues play an important role in eWOM communication and explain additional variance in eWOM partners' intentions and perceptions beyond and above the star ratings. In general, negative emotion words are the most important cues across various situations.In addition, this study provides initial evidence for the validity of automatic text analysis in studying eWOM. Linguistic indicators such as Negations, Negative Emotions, and Money can explain additional variance in eWOM partners' attitudes and emotions beyond and above the star ratings.

Full textAbstract:
The purpose of this study was to determine the degree to which selected communication tools used by teachers who teach online are positively perceived by their students in improving feelings of self-efficacy and motivation, and which tools may be perceived to be significantly more effective than the others. Students from the Florida Virtual School, a leader in online course delivery for grades 6-12, were surveyed to find their perceptions about how their teachers' use of email, Instant Messaging, chat, the telephone, discussion area, whiteboard, and assignment feedback affected their motivation and success in an online high school course. Correlations were done to discover if there were any significant relationships between variables that relate to teacher interaction and motivation. In addition, distributions of student responses to survey questions about digital communication tools and demographics were examined. It was found that there is a high degree of correlation between frequency of teachers' use of digital communication tools and student's perception of their level of motivation. It was also found that the digital communication tools most frequently used by teachers in communicating with their students were email, the telephone, and assignment feedback, and that the students found these same tools the most helpful in their learning. In addition, no significant demographic differences were found in students' perception of teacher's use of tools to enhance learning and motivation in their courses except in the number of previous online courses taken. These findings can help direct online high school teachers in their selection of digital tools used to communicate with their students.Ed.D.

Full textAbstract:
A thesis submitted in fulfilment of the requirements for the degree of Masters in Communication Science at the University of Zululand, South Africa, 2012.Majority of developing societies are usually succumbing to numerous socio-economic challenges. Communities in Maseru, the capital of Lesotho, are not excluded from this trend. Online collaborations are consequently at the heart of addressing these challenges. This study examines the probability of encouraging and engaging online communication for social and economic development in Maseru. The promises of online communication for transforming society and advancing the new economy have rested on the arguments that online communication could expand and widen access to electronic commerce, enhance the quality of distance education, improve the general quality and standard of living , and eventually improve the economy of Maseru. Information Communication Technologies (ICTs) are very powerful tools for diffusing knowledge and information to society which is a fundamental aspect of the development process. The presence of new communication technologies has a greater influence on human lives than we ever thought. It is imperative that every community in Lesotho examines ways and means of adopting their information communication technology (ICT) infrastructure as soon as possible or face the possibility of social and economic stagnation and isolation. The Internet has ushered in innovative ways of socialising and conducting business. Although it has, through the process of globalization, created a wide space to engage in business and eradicate poverty, many societies are still isolated. There are many reasons for this which could range from voluntary isolation, inadequate infrastructure, ignorance or sheer laziness. The study was conducted within the paradigm of both qualitative and quantitative methods. Stratified and simple random sampling techniques were used and this allowed the researcher to divide the population of Maseru into various Strata. This research explored why Maseru is slow to adopt ICTs to enhance their economic and social development. Revelations from the study will benefit this community and will also assist in making recommendations for overcoming economic and social decline.

Full textAbstract:
Programmers and engineers in the domains of high performance computing (HPC) and electronic system design have a shared goal: to define a structure for coordination and communication between nodes in a highly parallel network of processing tasks. Practitioners in both of these fields have recently encountered additional constraints that motivate the use of multiple types of processing device in a hybrid or heterogeneous platform, but constructing a working "program" to be executed on such an architecture is very time-consuming with current domain-specific design methodologies. In the field of HPC, research has proposed solutions involving the use of alternative computational devices such as FPGAs (field-programmable gate arrays), since these devices can exhibit much greater performance per unit of power consumption. The appeal of integrating these devices into traditional microprocessor-based systems is mitigated, however, by the greater difficulty in constructing a system for the resulting hybrid platform. In the field of electronic system design, a similar problem of integration exists. Many of the highly parallel FPGA-based systems that Xilinx and its customers produce for applications such as telecommunications and video processing require the additional use of one or more microprocessors, but coordinating the interactions between existing FPGA cores and software running on the microprocessors is difficult. The aim of my project is to improve the design flow for hybrid systems by proposing, firstly, an abstract representation of these systems and their components which captures in metadata their different models of computation and communication; secondly, novel design checking, exploration and optimisation techniques based around this metadata; and finally, a novel design methodology in which component and system metadata is used to generate software simulation models. The effectiveness of this approach will be evaluated through the implementation of two physical-layer telecommunications system models that meet the requirements of the 3GPP "LTE" standard, which is commercially relevant to Xilinx and many other organisations.

Full textAbstract:
This study was conducted to assess physical and perceptual properties of a tactile display for a vibrotactile notification system within the CIRMMT Live Electronics Framework (CLEF), a Max-based modular environment for composition and performance of live electronic music. The tactile display was composed of two rotating eccentric mass actuators driven by a PWM signal generated from an Arduino microcontroller. Physical measurements using an accelerometer were carried out in order to estimate intensity and spectral peak frequency as function of duty cycle of the PWM signal. In addition, three user-based studies were conducted to estimate perceptual vibrotactile absolute threshold, differential threshold and temporal differential threshold. Obtained results provided us with precise guidelines that facilitate the design of perceptually robust vibrotactile stimuli for our tactile application. A set of eight simple tactons (vibrotactile icons) was defined, whereafter an absolute identification test was conducted in order to estimate mean tacton recognition rates. Results were promising; mean tacton recognition rate was found to be 74 %. Based on all findings described above, a Max-based prototype used for exploration of tactile stimuli was developed. The prototype contained a library of tactile notification presets to be loaded into CLEF, along with a simple tacton editor for design of customized tactile events.Syftet med denna studie var att undersöka fysiska och perceptuella egenskaper hos en taktil display som designats för att presentera taktila notifikationssignaler till användare av CIRMMT Live Electronics Framework (CLEF), en Max-baserad modulär miljö för komposition och framförande av musikstycken som involverar Live Electronics. Live Electronics är ett begrepp som innefattar elektronik som används för att generera, processera eller modifiera ljud i realtid. Den taktila display som användes i denna studie var uppbyggd av två roterande excentriska massor, drivna av en pulsbreddsmodulerad signal som genereras av en Arduino mikrokontroller. Accelerometermätningar och tre användarbaserade studier genomfördes för att undersöka följande: intensitet och spektral toppfrekvens som funktion av pulskvot, sensorisk tröskel och intensitetsdiskriminering mellan presenterade stimuli, samt JND i millisekunder för två efterföljande taktila stimuli. Erhållna resultat analyserades varefter riktlinjer för design av perceptuellt robusta signaler för vår taktila display sattes upp. I slutfasen av studien designades åtta taktila signaler, varefter en användarbaserad studie genomfördes för att uppskatta hur lätta dessa signaler var att identifiera. En genomsnittlig identifikationsnivå på 74 % kunde noteras. Baserat på ovan beskrivna resultat utvecklades slutligen en taktil modulprototyp i form av ett bibliotek av fördefinierade taktila stimuli. Denna prototyp inkluderande även en funktion som gav användaren möjlighet att designa och skräddarsy egna taktila signaler.

Full textAbstract:
Thesis (MScEng)--University of Stellenbosch, 2011.ENGLISH ABSTRACT: The perceived quality of Voice over Internet Protocol (IP) (VoIP) communication relies on the network which is used to transport voice packets between the end points. Variable network characteristics such as bandwidth, delay and loss are critical for real-time voice traffic and are not always guaranteed by networks. It is important for network service providers to determine the Quality of Service (QoS) it provides to its customers. The solution proposed here is to predict the perceived quality of a VoIP call, in real-time by using network statistics. The main objective of this thesis is to develop a network analysis tool, which gathers meaningful statistics from network traffic. These statistics will then be used for predicting the perceived quality of a VoIP call. This study includes the investigation and deployment of two main components. Firstly, to determine call quality, it is necessary to extract the voice streams from captured network traffic. The extracted sound files can then be analysed by various VoIP quality models to determine the perceived quality of a VoIP call. The second component is the analysis of network characteristics. Loss, delay and jitter are all known to influence perceived call quality. These characteristics are, therefore, determined from the captured network traffic and compared with the call quality. Using the statistics obtained by the repeated comparison of the call quality and network characteristics, a network specific algorithm is generated. This Non-Intrusive Quality Prediction Algorithm (NIQPA) uses basic characteristics such as time of day, delay, loss and jitter to predict the quality of a real-time VoIP call quickly in a non-intrusive way. The realised algorithm for each network will differ, because every network is different. Prediction results can then be used to adapt either the network (more bandwidth, packet prioritising) or the voice stream (error correction, change VoIP codecs) to assure QoS.
AFRIKAANSE OPSOMMING: Die kwaliteit van spraak oor die internet (VoIP) kommunikasie is afhanklik van die netwerk wat gebruik word om spraakpakkies te vervoer tussen die eindpunte. Netwerk eienskappe soos bandwydte, vertraging en verlies is krities vir intydse spraakverkeer en kan nie altyd gewaarborg word deur netwerkverskaffers nie. Dit is belangrik vir die netwerk diensverskaffers om die vereiste gehalte van diens (QoS) te verskaf aan hul kliënte. Die oplossing wat hier voorgestel word is om die kwaliteit van ’n VoIP oproep intyds te voorspel, deur middel van die netwerkstatistieke. Die belangrikste doel van hierdie projek is om ’n netwerk analise-instrument te ontwikkel. Die instrument versamel betekenisvolle statistiek deur van netwerkverkeer gebruik te maak. Hierdie statistiek sal dan gebruik word om te voorspel wat die gehalte van ’n VoIP oproep sal wees vir sekere netwerk toestande. Hierdie studie berus op die ondersoek en implementering van twee belangrike komponente. In die eerste plek, moet oproep kwaliteit bepaal word. Spraakstrome word uit die netwerkverkeer onttrek. Die onttrekte klanklêers kan dan geanaliseer word deur verskeie spraak kwaliteitmodelle om die kwaliteitdegradasie van ’n spesifieke VoIP oproep vas te stel. Die tweede komponent is die analise van netwerkeienskappe. Pakkieverlies, pakkievertraging en bibbereffek is bekend vir hul invloed op VoIP kwaliteit en is waargeneem. Hierdie netwerk eienskappe word dus bepaal uit die netwerkverkeer en daarna vergelyk met die gemete gesprekskwaliteit. Statistiek word verkry deur die herhaalde vergelyking van gesprekkwaliteit en netwerk eienskappe. Uit die statistiek kan ’n algoritme (vir die spesifieke network) gegenereer word om spraakkwaliteit te voorspel. Hierdie Nie-Indringende Kwaliteit Voorspellings-algoritme (NIKVA), gebruik basiese kenmerke, soos die tyd van die dag, pakkie vertraging, pakkie verlies en bibbereffek om die kwaliteit van ’n huidige VoIP oproep te voorspel. Hierdie metode is vinnig, in ’n nie-indringende manier. Die gerealiseerde algoritme vir die verskillende netwerke sal verskil, want elke netwerk is anders. Die voorspelling van spraakgehalte kan dan gebruik word om òf die netwerk aan te pas (meer bandwydte, pakkie prioriteit) òf die spraakstroom aan te pas (foutkorreksie, verander VoIP kodering) om die goeie kwaliteit van ’n VoIP oproep te verseker.

Ying, Liangzhong. "A tool for using the control of character animation to help teach children communication skills." Thesis, University of Nottingham, 2012. http://eprints.nottingham.ac.uk/12692/.
Full textAbstract:
Effective Communication is an integral part of everyday life but recent studies show that in the UK many children fail to obtain this essential skill. The traditional approach to teaching communication skills is still important in school but new developments and the increasing availability of technology in the classroom, offer the potential for new ways to approach this teaching. A number of research institutions in the UK, for example the British Film Institute, are investigating how to use media such as films and television, in the classroom, in order to enhance children’s learning. Making cartoon films is a potentially valuable teaching approach but the lack of a suitable software tool to support this aspiration limits its viability. Existing software tools do reference the learning of communication skills as one of their features but they do not see this as a major learning objective. The aim of this thesis is to investigate three hypotheses based around the concept of using cartoon animation as a tool to enhance learning of communication. The first of these is that film production software which gives children control of character animation design may significantly stimulate their interest in exploring how to express their feelings. The second is that a correctly designed tool will integrate well into classroom teaching to produce effective learning and finally that the same tool can be used to extend learning of these skills outside the classroom. As a result a software tool has been developed to help children engage with the features of character animation, while learning how to express their feelings through storytelling in films. By using the tool, children experience the major steps of character animation design in filmmaking and in this process, each step is specially designed to fulfil their needs and stimulate them to use emotions. Experiments were carried out both in the classroom and out of school. The result indicated that older primary children had significant engagement in exploring emotional usage on the virtual characters and further analysis revealed children’s engagement was associated with age, social adjustment and computer experience. Moreover, using tool-assisted teaching in the classroom could bring some positive effects which do not exist with conventional teaching. In the out of school testing, around half of the children had positive reactions to accepting parental guidance and some of them (including their parents) had significant engagement in exploring emotional usage.

Mowbray, John Alexander. "The role of networking and social media tools during job search : an information behaviour perspective." Thesis, Edinburgh Napier University, 2018. http://researchrepository.napier.ac.uk/Output/1516318.
Full textAbstract:
This research reported in this thesis explores job search networking amongst 16-24 year olds living in Scotland, and the role of social media platforms (i.e. Facebook, Twitter, and LinkedIn) during this process. Networking is treated as an information behaviour; reflecting this, the study is underpinned by a prominent model from the domain of information science. A sequential, mixed methods approach was applied to gather data. This included the use of interviews, focus groups, and a survey questionnaire. The interviews incorporated ego-centric network methods to develop a relational perspective of job search networking. The findings show that young people accrue different types of information from network contacts which can be useful for all job search tasks. Indeed, frequent networking offline and on social media is associated with positive job search outcomes. This is especially true of engaging with family members and acquaintances, and frequent use of Facebook for job search purposes. However, demographic and other contextual factors have a substantial impact on the nature of networking behaviours, and the extent to which they can influence outcomes. Additionally, young jobseekers face a range of barriers to networking, do not always utilise their networks thoroughly, and are more likely to use social media platforms as supplementary tools for job search. A key contribution of this work is that it provides a detailed insight into the process of networking that has been neglected in previous studies. Its focus on social media also reveals a new dimension to the concept which has received little attention in the job search literature. Given its focus on young jobseekers living in Scotland, the findings have also been used to create a detailed list of recommendations for practitioners.

As ferramentas mais comuns da internet, tais como correio eletrônico, chat, fórum estão sendo rapidamente incorporadas nas atividades diárias das escolas, nos cursos presenciais. De modo especial isso acontece também nas instituições que fazem uso de sistemas de gerenciamento de cursos, que oferece um ambiente de aprendizagem colaborativa, de modo a provocar uma maior interação entre os alunos e uma aprendizagem com mais qualidade. O objetivo desta dissertação foi identificar quão as tecnologias de comunicação de um ambiente de aprendizagem colaborativa estão sendo utilizadas e agregando valor a formação dos alunos. Dados foram coletados de 102 alunos de disciplinas semi-presenciais do primeiro semestre de 2004, que responderam perguntas versando sobre o domínio sobre a tecnologia, a importância dada as ferramentas de colaboração na condução da disciplina, a identificação de algumas características dessas tecnologias em sua formação discente. Também foi elaborado um estudo de caso a partir de entrevistas com professores de uma Instituição de ensino superior. As ferramentas mais utilizadas foram o correio eletrônico e o fórum. O chat foi considerado uma ferramenta pouco utilizada, embora tenha sido considerada importante para o \"sentimento de grupo\". A videoconferência, considerada inviável pelo seu alto custo de operacionalização, foi raramente utilizada, muito embora suas características para simular a sala de aula tenham sido evidenciadas. Recomendações foram dadas em relação a treinamentos de instrutores e de futuras pesquisas considerando a visão dos professores.The most common tools of internet, such as electronic mail, chat and forum, are being rapidly incorporated in daily school activities.

The objective of this paper was to identify what communication technologies in a collaborative learning environment have being utilized and the value aggregated to the students background. Some data were collected from 102 students of school subjects in the first semester in the year of 2004. These students answered questions concerning the domain of technology, the importance given to the tools that collaborates on teaching the subject, the identification of technologies features for their background. It was also elaborated a study starting from interviews with professors of an upper teaching institution (college). The most utilized tools were the e-mail and forum. The chat wasn\'t considered a very utilized tool, although it has been considered important for the \"group sense\". The videoconference, considered impracticable by its high functional cost, was rarely utilized, although its characteristics to simulate the classroom have been highlighted. Some recommendations were made in relation to the training of instructors and of the future researches considering the professors point of view.

Full textAbstract:
A qualitative research was conducted to better understand the communication process connected with organizing musical festival for mass audience and the tools used to gain successful communication. Based on data collected by an interview with organizers and data found on the festival web site, theory about communication models of PR Smith and tools used in communication process, described by Kotler, were compared. One of the biggest music festivals in Europe – an Hungarian festival: the Sziget – has been chosen to evaluate its communication.
The findings show that, in terms of communication model, the company chooses the most appropriate to reach mass audience model. Mass communication model with small modifications seem to be the most appropriate for such a big organization like musical event. Communication tools used in case of a big festival also should concern about reaching mass audience. In order to do that, the tools focussed on more personal communication, such as direct marketing or personal selling can be given up in favour of tools such as advertising, publicity and PR or sales promotion, which give possibility to reach bigger audience in shorter period of time.

Full textAbstract:
In distance learning, ICT tools are used to bridge the instructional gap caused by physical distance between the lecturer and the student. Therefore, more effective communication tools can help to enhance the success of a distance learning curriculum. Communication barriers such as disconnectedness, conceptual confusion and lack of social pressure to perform, can negatively affect the success of distance learning. Careful design and implementation of contextually appropriate communication tools is vital in a distance learning curriculum. The University of Cape Town (UCT) Conversion Masters in Information Technology (MIT) originally used a tool called Vula for communication between staff and students, as well as student-to-student communication. Vula is UCT's implementation of the Sakai learning management system. Between 2016 and 2018, a major shift was observed in the adoption and use of communication tools within the programme. There was a noticeable decrease in dialogue between students and lecturers on Vula, and an increase in student-to-student communication using WhatsApp. In 2018, the Slack communication tool wasintroduced to the MIT degree with the objective of increasing communication and collaboration between students and lecturers. This study investigates the adoption and use of the three communication tools (Vula, WhatsApp and Slack) within the context of the University of Cape Town MIT programme. The research aims to provide an understanding of communication needs and practice that can inform the design of distance learning programmes and enable them to harness the potential of social communication tool features. The study describes the nature of communication within the UCT MIT degree. The research also explores the functional features of the tools and how they are used, and the frequency of interaction on the various communication platforms within the MIT programme. This is complemented by a survey of current MIT students and their perceptions. The research analysed 2605 communication messages in Vula (UCT's name for the Sakai learning management system), Slack and WhatsApp communication tools over the three-year transition period 2016-2018. Feedback from a student survey, in which 11 respondents completed a questionnaire after an interview, is also presented. Based on questionnaire responses from MIT students, Vula is viewed as the best tool for administrative matters, WhatsApp is preferred for sharing information and checking on peers, and Slack is perceived as best for communication with all types of participants - students, lecturers and tutors. Most respondents rated WhatsApp as accessible, convenient and providing a good experience, while far fewer did so for Vula and Slack. WhatsApp was also seen to be the tool students used to reinforce or follow up on communications posted on the other tools.

Perez, Gonzalez Enrique. "Advanced automatic mixing tools for music." Thesis, Queen Mary, University of London, 2010. http://qmro.qmul.ac.uk/xmlui/handle/123456789/614.
Full textAbstract:
This thesis presents research on several independent systems that when combined together can generate an automatic sound mix out of an unknown set of multi‐channel inputs. The research explores the possibility of reproducing the mixing decisions of a skilled audio engineer with minimal or no human interaction. The research is restricted to non‐time varying mixes for large room acoustics. This research has applications in dynamic sound music concerts, remote mixing, recording and postproduction as well as live mixing for interactive scenes. Currently, automated mixers are capable of saving a set of static mix scenes that can be loaded for later use, but they lack the ability to adapt to a different room or to a different set of inputs. In other words, they lack the ability to automatically make mixing decisions. The automatic mixer research depicted here distinguishes between the engineering mixing and the subjective mixing contributions. This research aims to automate the technical tasks related to audio mixing while freeing the audio engineer to perform the fine‐tuning involved in generating an aesthetically‐pleasing sound mix. Although the system mainly deals with the technical constraints involved in generating an audio mix, the developed system takes advantage of common practices performed by sound engineers whenever possible. The system also makes use of inter‐dependent channel information for controlling signal processing tasks while aiming to maintain system stability at all times. A working implementation of the system is described and subjective evaluation between a human mix and the automatic mix is used to measure the success of the automatic mixing tools.

This research presents new audio creation and processing tools for the virtual electronic music studio. The Tools were created by the author in the Max/MSP authoring environment. Some Tools model analog production techniques lost when studios moved inside computers, and provide additional functionality only possible in the digital world. Others make use of traditional processing ideas but add a level of control difficult to find in today's audio software plug-ins. The Tools are small, simple, real-time, and user-controllable devices for working with sound.

Full textAbstract:
The need for better machine tool accuracy is discussed together with the factors which can affect machine tool accuracy. A study is made of the various techniques adopted for the reduction of errors in machine tools. The concept of error compensation is discussed and the different techniques for error compensation are appraised. A critical appraisal is presented of the work undertaken to date in the field of error compensation. Based on this appraisal a criterion is established for a universally applicable error compensation system. The development of a novel, patented microprocessor based machine tool error compensation system which fulfills this criterion is described. This compensation system, which is based on the precalibrated compensation technique, utilizes a unique geometric compensation algorithm. This algorithm allows the compensation system to compensate for the geometric error components of any machine tool configuration up to three axes. The development of this geometric algorithm is presented. The integration of this compensation system to a large moving column milling machine is described. Measurement tests and cutting tests were performed on this milling machine to establish the effectiveness of the compensation system. The results from these experimental tests are presented, and illustrate the significant improvement in machine tool accuracy achieved through error compensation. This is the first attempt at producing a machine tool error compensation system with universal applicability, both in terms of the machine geometric model, and the method of applying the compensation to the machine tool. The error compensation system developed gives the potential for compensating for thermally induced and load induced position errors, and will enable further work in this area to be commercially exploited.

Roy, Scott Allen. "Simulation tools for the analysis of single electronic systems." Thesis, University of Glasgow, 1994. http://theses.gla.ac.uk/7655/.
Full textAbstract:
Developments in theory and experiment have raised the prospect of an electronic technology based on the discrete nature of electron tunnelling through a potential barrier. This thesis deals with novel design and analysis tools developed to study such systems. Possible devices include those constructed from ultrasmall normal tunnelling junctions. These exhibit charging effects including the Coulomb blockade and correlated electron tunnelling. They allow transistor-like control of the transfer of single carriers, and present the prospect of digital systems operating at the information theoretic limit. As such, they are often referred to as single electronic devices. Single electronic devices exhibit self quantising logic and good structural tolerance. Their speed, immunity to thermal noise, and operating voltage all scale beneficially with junction capacitance. For ultrasmall junctions the possibility of room temperature operation at sub picosecond timescales seems feasible. However, they are sensitive to external charge; whether from trapping-detrapping events, externally gated potentials, or system cross-talk. Quantum effects such as charge macroscopic quantum tunnelling may degrade performance. Finally, any practical system will be complex and spatially extended (amplifying the above problems), and prone to fabrication imperfection. This summarises why new design and analysis tools are required. Simulation tools are developed, concentrating on the basic building blocks of single electronic systems; the tunnelling junction array and gated turnstile device. Three main points are considered: the best method of estimating capacitance values from physical system geometry; the mathematical model which should represent electron tunnelling based on this data; application of this model to the investigation of single electronic systems.

Norman, David J. "Human traders need new tools." Thesis, University of Essex, 2016. http://repository.essex.ac.uk/17866/.
Full textAbstract:
This thesis proposes new methods and tools for helping human traders to compete in a high-frequency trading environment. Human traders have difficulty trading against predatory algorithms and the thesis proposes methods that support the creation of assistive tools that can help human traders to compete profitably. It also develops further understanding of classical decision-making theory in a realtime trading context demonstrating that human traders improve decision-making biases when linked together in groups or with an assistive machine. As described in the thesis human traders are monitored, and their data is captured, in realtime and in situ. The trading performance and behavioural characteristics of the traders are studied in this context in order to determine if they can be positively modified. The thesis presents a new model for studying human trading behaviour in realtime and in situ using unique software. It also describes the basis for the development of a range of interventionist and assistive tools that are designed to augment trading performance. The approach put forward is unique in its application. It also provides evidence that human traders are willing to allow machines to augment their trading decisions. The contributions of this thesis are that it overcomes the problem of assessing human trader risk-taking behaviour in realtime and in situ, it makes sense of human trading behaviour at realtime speeds and then it shows that, with new approaches to human-machine collaboration, trading performance improves and classic decision-making biases are reduced.

Full textAbstract:
This thesis investigates the perceptions of students about using mobile communication tools in web-based instruction. A mobile learning portal that can be used by different mobile devices was designed for this purpose. This portal included a mobile discussion forum and a course information system. Sixty
undergraduate and five graduate students from METU/CEIT department used this portal as a supportive learning activity in three different courses throughout two-three, and four-week periods. The discussion subjects related to course
content were created by instructors in these courses and students used this portal by sending messages or creating new subjects. Assignment results and announcements were inserted into the system by the instructors of these
courses. A user evaluation instrument was developed by the researcher and validated by field experts. At the end of the study, perceptions of students were collected about mobile learning, mobile learning technologies and mobile discussion forums by using this instrument. Descriptive statistics were calculated according to the responses of students.
The study results show that most of the students enjoyed using mobile technologies in education and they want to use mobile technologies in other courses. Although they like using mobile technologies, they did not increase the level of learning and motivation of the students much. Furthermore, mobile technologies did not increase the communication between students and between students and teachers despite their highly developed communication capabilities. Students could easily use the mobile technologies but small screen sizes and limited keypads hindered them from performing the operations. According to students, the cost of using mobile technologies is quite important whereas the data communication security is not important.

The scope of this thesis will be focused on the machine FORMA Z1 which is one ofthe most functional amongst the sort of machines currently available in the market. Itprovides faster tool changes besides a huge variety of tool layouts with the possibility ofmaking a product with one only set up. Furthermore, the combi-beam rotation capability,together with dual sets of tools, give to the machine an exceptional competence.Through this project, some of the shortcomings in the usability of the machine are evaluatedto be able to give an accurate solution to provide it of extra functionalities, thusacquiring better efficiency during the performance. This solution consists of the developmentof a device which will aid the operator during the tool arrangement of the machine.The solution includes a platform with a laser that will point out where the operator mustplace the corresponding tool. The system will know where to locate it because the realmachine would generate an XML file which would contain all necessary data. All thisdata will be read by a computer and send it to the microcontroller that will control allthe system.The solution proposed improves the throughput and reduces the time needed in the bendingprocess increasing the facility in the process of bending metal sheet. However, thereare some disadvantages on the implementation of this device. The new machine wouldbe more expensive and the software would be changed to include the new system and theprogram that reads the XML document.

In this thesis, we present a graphical computer-aided design (CAD) environment for the design, analysis and layout of printed electronic batteries in the first phase and the parasitic extraction of the connecting wires in the second phase. The primary motivation of our work is that this prototyping software tool so far does not exist. Our tool has been integrated within the existing CAD tool which allows quick prototyping and simplifies the interface between the system designer and the device manufacturer. This tools supports the schematic and layout entry, rule checking and netlist generation. The first phase of the device synthesis modelling is based on Enfucell printed batteries, by which using the CAD tool, the shape of the battery is optimized and designed to fit the product and is able to simulate the performance during the optimization, whereas the second phase is the parasitic extraction using an extracting tool named fasthenry, which is integrated to our CAD tool to extract unwanted resistance and inductance within the shared wires between the battery and other devices. We believe that the availability of this tool is useful to the CAD community for novel ideas in the circuit design for flexible hybrid electronics.+46764354255, +46722694942

Full textAbstract:
Pervasive computing proposes a new paradigm for human-computer interaction. By embedding computation, sensing, and networking into our daily environments, new computing systems can be developed that become helpful, supportive, and invisible elements of our lives. This tight proximity between the human and computational worlds poses challenges for the design of these systems - what disciplines should be involved in their design and what tools and processes should they follow? We address these issues by advocating for interdisciplinary design of pervasive computing systems. Based upon our experiences teaching courses in interactive architecture, product design, physical computing and through surveys of existing literature, we examine the challenges faced by interdisciplinary teams when developing pervasive computing systems. We find that teams lack accessible prototyping tools to express their design ideas across domains. To address this issue we propose a new software-based design tool called electronic storyboards.
We implement electronic storyboards by developing a domain-specific modeling language in the Eclipse Graphical Editor Framework. The key insight of electronic storyboards is to balance the tension between the ambiguity in drawn storyboards and the requirements of implementing computing systems. We implement a set of user-applied tags, perform layout analysis on the storyboard, and utilize natural language processing to extract behavioral information from the storyboard in the form of a timed automaton. This behavioral information is then transformed into design artifacts such as state charts, textual descriptions, and source code.
To evaluate the potential impact of electronic storyboards on interdisciplinary design teams we develop of user study based around ``boundary objects''. These objects are frequently used within computer-supported collaborative work to examine how objects mediate interactions between individuals. Teams of computing and non-computing participants were asked to storyboard pervasive computing systems and their storyboards were evaluated using a prototype electronic storyboarding tool. The study examines how teams use traditional storyboarding, tagging, tool queries, and generated artifacts to express design ideas and iterate upon their designs. From this study we develop new recommendations for future tools in architecture and fashion design based upon electronic storyboarding principles.
Overall, this study contributes to the expanding knowledge base of pervasive computing design tools. As an emerging discipline, standardized tools and platforms have yet to be developed. Electronic storyboards offer a solution to describe pervasive computing systems across application domains and in a manner accessible to multiple disciplines.Ph. D.

Full textAbstract:
This thesis investigates the usage problems of Online Collaborative Groupware (OCG) tools for learning at the University of Bahrain (UOB) in the Kingdom of Bahrain. An initial study revealed that the main problems faced by students when they use OCG tools in the learning process are security and trust. SWFG (Skype, Wiki, Facebook, and Gmail) tools were proposed as being effective and commonly used OCG tools for learning. A quasi-experiment has been done with UOB students to identify the perceptions of the students towards security, privacy and safety relating to use of SWFG tools. Based on this experiment the researcher has derived the following results: Secure Skype has a positive relationship with Skype usage; Private Skype has a positive relationship with Skype trust; Secure Gmail has a negative relationship with Gmail usage and trust; Wiki usage has a negative relationship with trust in Wikis. Additionally, the research revealed that students may be more motivated to use OCG tools if the security and privacy of these tools was to be improved. The thesis also focuses on security and trust within email. In order to evaluate the usage of secure emails, students‘ awareness of the secure email awareness was investigated using quantitative and qualitative methods. The results of this evaluation informed the design of an experiment that was then conducted by tracking secure email usage and gathering information about the students‘ usage and awareness of their secure emails. The aim of this activity was to identify a clear representation of secure email usage over specified periods for both academic and non-academic purposes by students in both the UK and Bahrain. It has been concluded from this experiment that there are differences between the usage of secure email in each country when applied to both academic and non-academic purposes. Finally, based on these results, the researcher developed a framework which derives from the Technology Acceptance Model (TAM) model by testing security and trust effects on the ease of use and on usefulness. A case study has been conducted using a new secure email instructional model in order to validate the research framework. The study found that security provided by webmails and students‘ trust affects the webmail‘s perceived usefulness, and that in turn this leads to ease of use regardless of which type of email client is used. However, it was not proof that usefulness affects the usage of email. Evidence suggests that the model may be a suitable solution for increasing the usefulness of email in Computer Supported Collaborative Learning (CSCL), and can help to strengthen communication between faculty and students. This study has contributed valuable knowledge and information in this particular field of study. It has been able to gather a satisfactory amount of information from both students and teachers in both the University of Bahrain (UOB) and the University of Warwick (UOW). A number of different methods were used in this task – interviews, questionnaires, observations, experiments and student feedback, amongst others. The entire study was conducted in a way that it would empirically evaluate different dimensions of secure Online Collaborative Groupware (OCG) tools usage in the educational environment. The research framework applied in this investigation provided many insights into OCG tools. These new insights and information may be used to test and validate the framework with a large number of students.

Full textAbstract:
Machine-assisted formal proofs are becoming commonplace in certain fields of mathematics and theoretical computer science. New formal systems and variations on old ones are constantly invented. The meta-theory of such systems, i.e. proofs about the system as opposed to proofs within the system, are mostly done informally with a pen and paper. Yet the meta-theory of deductive systems is an area which would obviously benefit from machine support for formal proof. Is the software currently available sufficiently powerful yet easy enough to use to make machine assistance for formal meta-theory a viable proposition? This thesis presents work done by the author on formalizing proof theory from [DP97a] in various formal systems: SEQUEL [Tar93, Tar97], Isabelle [Pau94] and Coq [BB+96]. SEQUEL and Isabelle were found to be difficult to use for this type of work. In particular, the lack of automated production of induction principles in SEQUEL and Isabelle undermined confidence in the resulting formal proofs. Coq was found to be suitable for the formalisation methodology first chosen: the use of nameless dummy variables (de Bruijn indices) as pioneered in [dB72]. A second approach (inspired by the work of McKinna and Pollack [vBJMR94, MP97]) formalising named variables was also the subject of some initial work, and a comparison of these two approaches is presented. The formalisation was restricted to the implicational fragment of propositional logic. The informal theory has been extended to cover full propositional logic by Dyckhoff and Pinto, and extension of the formalisation using de Bruijn indices would appear to present few difficulties. An overview of other work in this area, in terms of both the tools and formalisation methods, is also presented. The theory formalised differs from other such work in that other formalisations have involved only one calculus. [DP97a] involves the relationships between three different calculi. There is consequently a much greater requirement for equality reasoning in the formalisation. It is concluded that a formalisation of any significance is still difficult, particularly one involving multiple calculi. No tools currently exist that allow for the easy representation of even quite simple systems in a way that fits human intuitions while still allowing for automatic derivation of induction principles. New work on integrating higher order abstract syntax and induction may be the way forward, although such work is still in the early stages.

Full textAbstract:
This thesis presents the synthesis and characterisation of a range of heterometallated porphyrin oligomers and other novel 3D π-conjugated porphyrin nanostructures. Subsequently, their physical organic properties were evaluated which revealed some fascinating electronic properties. Chapter 1 summarises some of the work done in the Anderson group on porphyrin nanostructures and reviews the literature regarding heterometallated porphyrin oligomers. In addition it introduces the main concepts and techniques used in the remainder of the thesis. In Chapter 2 the stabilities of a family of four linear porphyrin pentamer complexes are determined by UV-vis-NIR titrations and analysed using chemical double-mutant cycles which reveal that the binding energy of the copper centre to an axial pyridine ligand is -6.2 kJ mol-1. Subsequently, the Zn-Zn-Cu-Zn-Zn pentamer is used in the synthesis of a heterometallated 10-porphyrin nanoring. Chapter 3 will describe the investigation of quantum interference phenomena in a bis-copper six-porphyrin nanoring by using EPR spectroscopy. We show that the exchange coupling between two spin centres is increased by a factor 4.5 in the ring structure with two parallel coupling pathways as compared to an otherwise identical system with just one coupling path. In Chapter 4 the syntheses of three isomers of the bis-copper 6-porphyrin nanoring are described. DFT calculations have indicated potential destructive interference phenomena in one of the isomers which would allow for the formation of a molecular system with behaviour resembling that of a hypothetical molecular interferometer. Chapter 5 reports on the template-directed synthesis of a π-conjugated 14-porphyrin nanoball. This bicyclic structure consists of two intersecting nanorings of 6 and 10 porphyrin units. Fluorescence up-conversion spectroscopy experiments demonstrate that electronic excitation delocalises over the whole 3D π-system within 0.3 ps if the nanoball is bound to its templates or within 5 ps if the nanoball is empty. In Chapter 6 the synthesis and characterisation of a D4h symmetric analogue of the porphyrin nanoball is described. The structure consists of ten porphyrin units arranged as two perpendicular 6-porphyrin nanorings intersecting at two porphyrins. In the synthesis, a combination of magnesium and zinc porphyrins are used which allows for the introduction of a selective demetallation method crucial for accessing this novel structure.

Full textAbstract:
Electronic communication is becoming an integral part of the communication structure within organisations, but the costs and benefits are not being assessed. Communication by email is usually assumed to be an efficient and effective means of sending messages. However, on analysis the process is seen to be much more complex and much less efficient than is normally assumed. Communication is carried out in many different forms, but the common underlying motive of communication is to improve working practices and to increase productivity. As communication pervades nearly everything we do, even small improvements in the effectiveness and cost of our communication processes can have significant benefits. The aim of this research was to analyse the cost effectiveness of using email and to suggest ways in which the cost effectiveness can be improved. A number of studies have been conducted into the cost effectiveness of email within organisations. The studies were carried out mainly at the Danwood Group, the company sponsoring the author's PhD research. The Danwood Group has just over 500 employees at 19 sites around the UK and its head office is based in Lincoln, where all of the email case studies in this thesis where undertaken. The Danwood Group retails office equipment, predominately photocopiers. Email behaviour was monitored by the use of software at the Danwood Group. This raised a number of questions on the ethical issues of electronic monitoring. This thesis explores these issues and proposes a set of guidelines to allow electronic monitoring within strict professional and ethical guidelines. The Danwood Group studies examined how and when email was used. It was found that, when the company first started using email, over two thirds of messages were non-business-related, though this dropped to less than half in a few months. It was also found that many messages could be delivered in one line of text. A one-line message service was introduced and this was found to save employee time for both senders and receivers of the messages. A costing formula was developed measuring the human cost of operating email messaging. The final study was to determine how long it took employees to recover and return to normal work after an email interruption and this was compared with published data for telephone interrupts. From these results a set of guidelines were developed to enable companies to make the most efficient use of email. The thesis concludes by identifying further areas of research into email usage that would help give a better understanding of methods to enable email to become even more cost effective.

Full textAbstract:
The necessity for scientists and others to use consistent terminology has recently been regarded as fundamental to advancing scientific research, particularly where data from disparate sources must be shared, compared or integrated. One area where there are significant difficulties with the quality of collected data is the field of taxonomic description. Taxonomic description lies at the heart of the classification of organisms and communication of ideas of biodiversity. As part of their working practice, taxonomists need to gather descriptive data about a number of specimens on a consistent basis for individual projects. Collecting semantically well-defined structured data could improve the clarity and comparability of such data. No tools however currently exist to allow taxonomists to do so within their working practice. Ontologies are increasingly used to describe and define complex domain data. As a part of related research an ontology of descriptive terminology for controlling the storage and use of flowering plant description data was developed. This work has applied and extended model-based user interface development environments to utilise such an ontology for the automatic generation of appropriate data entry interfaces that support semantically well defined and structured descriptive data. The approach taken maps the ontology to a system domain model, which a taxonomist can then specialise using their domain expertise, for their data entry needs as required for individual projects. Based on this specialised domain knowledge, the system automatically generates appropriate data entry interfaces that capture data consistent with the original ontology. Compared with traditional model-based user automatic interface development environments, this approach also has the potential to reduce the labour requirements for the expert developer. The approach has also been successfully tested to generate data entry interfaces based on an XML schema for the exchange of biodiversity datasets.

Full textAbstract:
With the advent of the Internet, distributed programming has become a necessity for the majority of application domains. Nevertheless, programming distributed systems remains a delicate and complex task. This dissertation explores separating distribution concerns,
the process of transforming a centralized monolithic program into a distributed one. This research develops algorithms, techniques, and tools for separating distribution concerns
and evaluates the applicability of the developed artifacts by identifying the distribution
concerns that they separate and the common architectural characteristics of the centralized programs that they transform successfully. The thesis of this research is that software tools working with standard mainstream languages, systems software, and virtual machines can effectively and efficiently separate distribution concerns from application logic for object-oriented programs that use multiple distinct sets of resources. Among the specific technical contributions of this dissertation are (1) a general algorithm for call-by-copy-restore semantics in remote procedure calls for linked data structures, (2) an analysis heuristic that determines which application objects get passed to which parts of native (i.e., platform-specific) code in the language runtime system for platform-independent binary code applications, (3) a technique for injecting code in such applications that will convert objects to the right representation so that they can be accessed correctly inside both application
and native code, (4) an approach to maintaining the Java centralized concurrency and synchronization semantics over remote procedure calls efficiently, and (5) an approach to enabling the execution of legacy Java code remotely from a web browser.
The technical contributions of this dissertation have been realized in three software tools for separating distribution concerns: NRMI, middleware with copy-restore semantics; GOTECH, a program generator for distribution; and J-Orchestra, an automatic partitioning system. This dissertation presents several case studies of successfully applying the developed
tools to third-party programs.
