Abstract:
Genetic algorithms (GAs) are a particular class of evolutionary algorithms that use techniques inspired by evolutionary biology such as inheritance, mutation, selection, and crossover to find best solutions to optimization and search problems. GAs are used in wide variety of applications in fields ranging from computer science, engineering, evolvable hardware, economics, mathematics, physics and biogenetics to name a few. A fast Fourier transform (FFT) is an efficient algorithm to compute the discrete Fourier transform (DFT) and it’s inverse. An FFT processor is used in applications such as signal processing and telecommunications, etc. It is one of the most power consuming block in wireless receivers such as Multi-Carrier Code Division Multiple Access (MC-CDMA). The portability requirement of these receiver systems imposes the need of low power architectures. Thus, designing an FFT processor with low power consumption is of crucial importance for overall system power. Power consumption of an FFT processor depends on the size of word length of the FFT coefficients. One way to reduce the power consumption in this processor is by reducing the switching activity in the FFT coefficients. This can be achieved using smaller word length for the FFT coefficients. This in turn reduces the SNR in the output signals of the FFT. This thesis investigates the impact of word length optimization of FFT coefficients on switching activity and SNR using GAs. The quality of GAs solutions are compared with non-GA solutions in order to determine the feasibility of using GAs to achieve optimum performance in terms of switching activity and SNR. Results show that GAs can find solutions with smaller word length and have significant reductions in switching compared to the non-GA solutions. This thesis also investigates some of the varying parameter settings, such as mutation domain, population size, crossover rate and mutation probability in the GAs, which affects the quality of search performance towards convergence and the speed of convergence.

Abstract:
Very Long Instruction Word (VLIW) processors are wide-issue statically scheduled processors. Instruction scheduling for these processors is performed by the compiler and is therefore a critical factor for its operation. Some VLIWs are clustered, a design that improves scalability to higher issue widths while improving energy efficiency and frequency. Their design is based on physically partitioning the shared hardware resources (e.g., register file). Such designs further increase the challenges of instruction scheduling since the compiler has the additional tasks of deciding on the placement of the instructions to the corresponding clusters and orchestrating the data movements across clusters. In this thesis we propose instruction scheduling optimizations for energy-efficient VLIW processors. Some of the techniques aim at improving the existing state-of-theart scheduling techniques, while others aim at using compiler techniques for closing the gap between lightweight hardware designs and more complex ones. Each of the proposed techniques target individual features of energy efficient VLIW architectures. Our first technique, called Aligned Scheduling, makes use of a novel scheduling heuristic for hiding memory latencies in lightweight VLIW processors without hardware load-use interlocks (Stall-On-Miss). With Aligned Scheduling, a software-only technique, a SOM processor coupled with non-blocking caches can better cope with the cache latencies and it can perform closer to the heavyweight designs. Performance is improved by up to 20% across a range of benchmarks from the Mediabench II and SPEC CINT2000 benchmark suites. The rest of the techniques target a class of VLIW processors known as clustered VLIWs, that are more scalable and more energy efficient and operate at higher frequencies than their monolithic counterparts. The second scheme (LUCAS) is an improved scheduler for clustered VLIW processors that solves the problem of the existing state-of-the-art schedulers being very susceptible to the inter-cluster communication latency. The proposed unified clustering and scheduling technique is a hybrid scheme that performs instruction by instruction switching between the two state-of-the-art clustering heuristics, leading to better scheduling than either of them. It generates better performing code compared to the state-of-the-art for a wide range of inter-cluster latency values on the Mediabench II benchmarks. The third technique (called CAeSaR) is a scheduler for clustered VLIW architectures that minimizes inter-cluster communication by local caching and reuse of already received data. Unlike dynamically scheduled processors, where this can be supported by the register renaming hardware, in VLIWs it has to be done by the code generator. The proposed instruction scheduler unifies cluster assignment, instruction scheduling and communication minimization in a single unified algorithm, solving the phase ordering issues between all three parts. The proposed scheduler shows an improvement in execution time of up to 20.3% and 13.8% on average across a range of benchmarks from the Mediabench II and SPEC CINT2000 benchmark suites. The last technique, applies to heterogeneous clustered VLIWs that support dynamic voltage and frequency scaling (DVFS) independently per cluster. In these processors there are no hardware interlocks between clusters to honor the data dependencies. Instead, the scheduler has to be aware of the DVFS decisions to guarantee correct execution. Effectively controlling DVFS, to selectively decrease the frequency of clusters with slack in their schedule, can lead to significant energy savings. The proposed technique (called UCIFF) solves the phase ordering problem between frequency selection and scheduling that is present in existing algorithms. The results show that UCIFF produces better code than the state-of-the-art and very close to the optimal across the Mediabench II benchmarks. Overall, the proposed instruction scheduling techniques lead to either better efficiency on existing designs or allow simpler lightweight designs to be competitive against ones with more complex hardware.

Abstract:
This experimental study examined the effects of word processing on revision and writing quality of expository compositions produced by seventh—graders. Thirty—six students in two accelerated English classes served as subjects. Prior to the experimental period, all students completed a handwritten composition (pretest) and received identical instruction in (a) composing and revising and (b) using a word processor. One intact class was randomly assigned as the experimental group. During the six-week treatment period all students wrote six compositions (three drafts per composition). The experimental group completed all composing and revising on the computer and the control group completed their compositions with pen and paper. Posttest l (produced on computer in the experimental group and by hand in the control group) and posttest 2 (handwritten in both groups) were analyzed for the frequency and types of revisions made between first and second drafts. The pretest and three posttests were analyzed for writing quality of final drafts. There were no significant differences: (a) between groups in the number of revisions in posttest l (computer written by experimental subjects and handwritten by control subjects), (b) in percentage of high—level revisions made with and without the word processor, and (c) in quality of compositions produced with and without the computer. There was a significant difference between groups in the number of revisions in handwritten compositions (posttest 2) produced by both groups after the treatment; the word processing group revised more frequently than did the group not exposed to six weeks of word processing. The experimental subjects also significantly increased in frequency of revisions from the time of posttest l (computer written) to posttest 2 (handwritten). A significant difference across time in writing quality scores was found. The findings suggested that students who compose and revise on computer can make substantially more revisions when they resume pen and paper composing and revising; however, use of the word processor does not differentially affect types of revisions attempted or writing quality. Word processors increase motivation, and adequate systems may increase the ability to detect and eliminate textual problems. Recommendations for research, theory, and instruction are discussed.

Abstract:
Afin de limiter leur coût et/ou leur consommation électrique, certains processeurs embarqués sacrifient le support matériel de l'arithmétique à virgule flottante. Pourtant, pour des raisons de simplicité, les applications sont généralement spécifiées en utilisant l'arithmétique à virgule flottante. Porter ces applications sur des processeurs embarqués de ce genre nécessite une émulation logicielle de l'arithmétique à virgule flottante, qui peut sévèrement dégrader la performance. Pour éviter cela, l'application est converti pour utiliser l'arithmétique à virgule fixe, qui a l'avantage d'être plus efficace à implémenter sur des unités de calcul entier. La conversion de virgule flottante en virgule fixe est une procédure délicate qui implique des compromis subtils entre performance et précision de calcul. Elle permet, entre autre, de réduire la taille des données pour le coût de dégrader la précision de calcul. Par ailleurs, la plupart de ces processeurs fournissent un support pour le calcul vectoriel de type SIMD (Single Instruction Multiple Data) afin d'améliorer la performance. En effet, cela permet l'exécution d'une opération sur plusieurs données en parallèle, réduisant ainsi le temps d'exécution. Cependant, il est généralement nécessaire de transformer l'application pour exploiter les unités de calcul vectoriel. Cette transformation de vectorisation est sensible à la taille des données ; plus leurs tailles diminuent, plus le taux de vectorisation augmente. Il apparaît donc un compromis entre vectorisation et précision de calcul. Plusieurs travaux ont proposé des méthodologies permettant, d'une part la conversion automatique de virgule flottante en virgule fixe, et d'autre part la vectorisation automatique. Dans l'état de l'art, ces deux transformations sont considérées indépendamment, pourtant elles sont fortement liées. Dans ce contexte, nous étudions la relation entre ces deux transformations, dans le but d'exploiter efficacement le compromis entre performance et précision de calcul. Ainsi, nous proposons d'abord un algorithme amélioré pour l'extraction de parallélisme SLP (Superword Level Parallelism ; une technique de vectorisation). Puis, nous proposons une nouvelle méthodologie permettant l'application conjointe de la conversion de virgule flottante en virgule fixe et de l'exploitation du SLP. Enfin, nous implémentons cette approche sous forme d'un flot de compilation source-à-source complètement automatisé, afin de valider ces travaux. Les résultats montrent l'efficacité de cette approche, dans l'exploitation du compromis entre performance et précision, vis-à-vis d'une approche classique considérant ces deux transformations indépendamment
In order to cut-down their cost and/or their power consumption, many embedded processors do not provide hardware support for floating-point arithmetic. However, applications in many domains, such as signal processing, are generally specified using floating-point arithmetic for the sake of simplicity. Porting these applications on such embedded processors requires a software emulation of floating-point arithmetic, which can greatly degrade performance. To avoid this, the application is converted to use fixed-point arithmetic instead. Floating-point to fixed-point conversion involves a subtle tradeoff between performance and precision ; it enables the use of narrower data word lengths at the cost of degrading the computation accuracy. Besides, most embedded processors provide support for SIMD (Single Instruction Multiple Data) as a mean to improve performance. In fact, this allows the execution of one operation on multiple data in parallel, thus ultimately reducing the execution time. However, the application should usually be transformed in order to take advantage of the SIMD instruction set. This transformation, known as Simdization, is affected by the data word lengths ; narrower word lengths enable a higher SIMD parallelism rate. Hence the tradeoff between precision and Simdization. Many existing work aimed at provide/improving methodologies for automatic floating-point to fixed-point conversion on the one side, and Simdization on the other. In the state-of-the-art, both transformations are considered separately even though they are strongly related. In this context, we study the interactions between these transformations in order to better exploit the performance/accuracy tradeoff. First, we propose an improved SLP (Superword Level Parallelism) extraction (an Simdization technique) algorithm. Then, we propose a new methodology to jointly perform floating-point to fixed-point conversion and SLP extraction. Finally, we implement this work as a fully automated source-to-source compiler flow. Experimental results, targeting four different embedded processors, show the validity of our approach in efficiently exploiting the performance/accuracy tradeoff compared to a typical approach, which considers both transformations independently

Abstract:
Les processeurs intégrés dans des domaines critiques exigent une combinaison de fiabilité, de performances et de faible consommation d'énergie. Very Large Instruction Word (VLIW) processeurs améliorent les performances grâce à l'exploitation ILP (Instruction Level Parallelism), tout en maintenant les coûts et la puissance à un niveau bas. L’ILP étant fortement dépendant de l'application, le processeur n'utilise pas toutes ses ressources en permanence et ces ressources peuvent donc être utilisées pour l'exécution d'instructions redondantes. Cette thèse présente une méthodologie d’injection fautes pour processeurs VLIW et trois mécanismes matériels pour traiter les pannes légères, permanentes et à long terme menant à trois contributions.La première contribution présente un schéma d’analyse du facteur de vulnérabilité architecturale et du facteur de vulnérabilité d’instruction pour les processeurs VLIW. Une méthodologie d’injection de fautes au niveau de différentes structures de mémoire est proposée pour extraire les capacités de masquage architecture / instruction du processeur. Un schéma de classification des défaillances de haut niveau est présenté pour catégoriser la sortie du processeur. La deuxième contribution explore les ressources inactives hétérogènes au moment de l'exécution, à l'intérieur et à travers des ensembles d'instructions consécutifs. Pour ce faire, une technique d’ordonnancement des instructions optimisée pour le matériel est appliquée en parallèle avec le pipeline afin de contrôler efficacement la réplication et l’ordonnancement des instructions. Suivant les tendances à la parallélisation croissante, une conception basée sur les clusters est également proposée pour résoudre les problèmes d’évolutivité, tout en maintenant une pénalité surface/énergie raisonnable. La technique proposée accélère la performance de 43,68% avec une surcoût en surface et en énergie de ~10% par rapport aux approches existantes. Les analyses AVF et IVF évaluent la vulnérabilité du processeur avec le mécanisme proposé.La troisième contribution traite des défauts persistants. Un mécanisme matériel est proposé, qui réplique au moment de l'exécution les instructions et les planifie aux emplacements inactifs en tenant compte des contraintes de ressources. Si une ressource devient défaillante, l'approche proposée permet de relier efficacement les instructions d'origine et les instructions répliquées pendant l'exécution. Les premiers résultats de performance d’évaluation montrent un gain de performance jusqu’à 49% sur les techniques existantes.Afin de réduire davantage le surcoût lié aux performances et de prendre en charge l’atténuation des erreurs uniques et multiples sur les transitoires de longue durée (LDT), une quatrième contribution est présentée. Nous proposons un mécanisme matériel qui détecte les défauts toujours actifs pendant l'exécution et réorganise les instructions pour utiliser non seulement les unités fonctionnelles saines, mais également les composants sans défaillance des unités fonctionnelles concernées. Lorsque le défaut disparaît, les composants de l'unité fonctionnelle concernés peuvent être réutilisés. La fenêtre de planification du mécanisme proposé comprend deux ensembles d'instructions pouvant explorer des solutions d'atténuation lors de l'exécution de l'instruction en cours et de l'instruction suivante. Les résultats obtenus sur l'injection de fautes montrent que l'approche proposée peut atténuer un grand nombre de fautes avec des performances, une surface et une surcharge de puissance faibles
Embedded processors in critical domains require a combination of reliability, performance and low energy consumption. Very Long Instruction Word (VLIW) processors provide performance improvements through Instruction Level Parallelism (ILP) exploitation, while keeping cost and power in low levels. Since the ILP is highly application dependent, the processor does not use all its resources constantly and, thus, these resources can be utilized for redundant instruction execution. This thesis presents a fault injection methodology for VLIW processors and three hardware mechanisms to deal with soft, permanent and long-term faults leading to three contributions. The first contribution presents an Architectural Vulnerability Factor (AVF) and Instruction Vulnerability Factor (IVF) analysis schema for VLIW processors. A fault injection methodology at different memory structures is proposed to extract the architectural/instruction masking capabilities of the processor. A high-level failure classification schema is presented to categorize the output of the processor. The second contribution explores heterogeneous idle resources at run-time both inside and across consecutive instruction bundles. To achieve this, a hardware optimized instruction scheduling technique is applied in parallel with the pipeline to efficiently control the replication and the scheduling of the instructions. Following the trends of increasing parallelization, a cluster-based design is also proposed to tackle the issues of scalability, while maintaining a reasonable area/power overhead. The proposed technique achieves a speed-up of 43.68% in performance with a ~10% area and power overhead over existing approaches. AVF and IVF analysis evaluate the vulnerability of the processor with the proposed mechanism.The third contribution deals with persistent faults. A hardware mechanism is proposed which replicates at run-time the instructions and schedules them at the idle slots considering the resource constraints. If a resource becomes faulty, the proposed approach efficiently rebinds both the original and replicated instructions during execution. Early evaluation performance results show up to 49\% performance gain over existing techniques.In order to further decrease the performance overhead and to support single and multiple Long-Duration Transient (LDT) error mitigation a fourth contribution is presented. We propose a hardware mechanism, which detects the faults that are still active during execution and re-schedules the instructions to use not only the healthy function units, but also the fault-free components of the affected function units. When the fault faints, the affected function unit components can be reused. The scheduling window of the proposed mechanism is two instruction bundles being able to explore mitigation solutions in the current and the next instruction execution. The obtained fault injection results show that the proposed approach can mitigate a large number of faults with low performance, area, and power overhead

Abstract:
In this study, the effect of the word processor on third semester Spanish students at the University of Arizona was examined. The study was performed over two semesters, using a control and an experimental group each time. The communicative language approach for second language learning was implemented in a cooperative learning environment for both control and experimental groups. Control groups used paper and pencil to write their class essays and experimental groups used the word processor. The experimental groups outperformed the control groups. The semester variable by itself was also significant. However, there was no significant interaction between group and semester. Replication studies are needed to validate the results of this study.

Abstract:
Three male year nine students with learning disabilities were given an intervention program that involved use of a word processor to write science fiction stories. The program was conducted over a five-week period. The effects of the use of the word processor alone were compared to the effects of the provision of an interactive teaching course program in conjunction with a word processor. The treatment program was a single subject treatment design. One participant's writing improved to an equal extent whether or not an interactive teaching program was provided. A second participant's fluency, spelling and the number of unique words written improved more if an interactive program that provided feedback were provided than if he used the word processor alone. The mechanics of his writing improved regardless of the provision of an interactive program. The third participant's spelling improved more if an interactive teaching program that provided feedback were provided. The mechanics of his writing improved regardless of the provision of the interactive program.

Abstract:
In order to discover to what extent the use of the word processor affects the motivation of high school students when engaged in writing tasks, and to determine the effects of the word processing on the length and quality of their work and editing, two groups, carefully matched in terms of prior computer experience, intelligence and language ability were given eight writing tasks. The test group used word processors while the control group used pen and paper. Their behaviour was closely observed and their writing was subsequently compared. It was found that while the test group were more motivated and spent longer both writing and editing their work, the quality of the work of both groups was similar. The degree of editing was greater for the test group. The conclusion is that there is a place for the use of the word processor in the English classroom, but specific strategies need to be developed to optimise its benefits.

Abstract:
Computers have been used effectively to provide support for people with a variety of special needs. One such group is adults with dyslexia. Dyslexia is commonly recognised as a learning disorder characterised by reading, writing and spelling difficulties. It inhibits recognition and processing of graphic symbols, particularly those pertaining to language. Computers are a useful aid for dyslexic adults, especially word processors and their associated spelling tools. However, there are still areas where improvements are needed. Creating an environment, which minimises visual discomfort associated with proof reading and making selections from lists would be of benefit. Furthermore providing the correct type and level of support for spelling, grammar and sentence construction may result in higher standards being achieved. A survey of 250 dyslexic adults established their requirements and enabled the development of a specialist word processing system and associated spelling support tools. The hypothesis, that using a language with enforced structure and rigid constraints has a positive affect for dyslexic adults, was also tested. A support tool, which provided a controlled environment, to assist with sentence construction for dyslexic adults was developed from this. Three environments were created using the word processing system: environment 1 used the basic system with no support, environment 2 provided spelling support suggested by the survey subjects and environment 3 used the sentence constructing tool providing support and control. Using these environments in controlled experiments indicated that although environment 2 achieved high academic standards, environment 3 produced written work to an even higher standard and at the same time, the subjects derived greater satisfaction in using it. This research proves that working in a controlled, rigid environment, where structure is enforced, substantially benefits dyslexic adults performing computer-based writing tasks.

Abstract:
随着社会的发展，尤其是互联网的发展，很多语言每年都涌现出了不少新词汇。词语是每个语言最基本也是最重要的组成部分，因此分析这些新词汇的结构特点以及构词法是很有意义的。这篇文章分析了2014年出现在中文里的新词汇和它们的构词方式，论文的目的是为了更好地了解中文词汇的发展和特点。本文以《2014汉语新词语》中公布的2014年出现的新词汇作为语料进行分析，发现了以下两个主要特点：第一，合成法，派生法，缩略法是2014年产生的新词汇的主要构词方式；第二， 百分之七十二的新词汇是多音节词（包含三个或者三个以上音节），而百分之八十的是名词。这些特点说明中文词汇现阶段的特点和发展趋势，跟传统的中文词汇有不同之处。
The aim of this thesis was to investigate how new Chinese words are formed and to examine the linguistic patterns among them. This thesis focused on the analysis of Chinese words formed in 2014. The quantitative data for the analysis included a collection of 423 new Chinese words from the book 2014 汉语新词语 (hànyǔxīn cíyǔ) by Hou and Zhou. Parts of speech and number of syllables in the new words were investigated, although the focus was on word-formation processes. A discussion of derivation, blending, abbreviation, analogy, borrowing, change of meaning, compounding and inventions is also included. The share of each word-formation process used for each of the new words was presented statistically in order to reveal the significance of each word-formation process. The analysis showed that compounding, derivation and abbreviation were the major word-formation processes in 2014. The study also suggests that words formed by derivation and analogy were much more frequent in 2014, in comparison to previous studies. Furthermore, the ways words are formed in Chinese are changing and evolving, as some word-formation processes are becoming more frequently used in the formation of new words.

Abstract:
In this thesis we show that lexical decisions (LDT) to isolated words are slowed when a target word has either, many orthographic competitors (defined as words sharing outer letter frames), or a single strong competitor (defined as words sharing all letters, e.g. from/form). This result is not found for naming latencies. It is shown that naming is more sensitive to variables which concern the mapping of orthography to phonology, than to purely orthographic measures. In contrast to these findings Andrews (1989, 1992) found that the existence of orthographic competitors in the form of neighbours (Coltheart, Davelaar, Jonasson and Besner (1977)), facilitated both LDT and naming responses. This suggests that neighbours conspire rather than compete for recognition. We repeat Andrews' experiments and replicate the conspiracy effect of neighbourhood size for low frequency words. Andrews' results replicate however, only for LDT and not for naming. In a further investigation of neighbourhood effects we measure eye fixations to target words in neutral sentence contexts. Here we find an effect of neighbourhood size for both high and low frequency words. The effect is, however, one of conspiracy for high frequency words, and one of competition for low frequency words. We describe an activation time course model of word processing which we argue can account for both competition and conspiracy effects, and for the differences in effects for high and low frequency words. Neighbourhood influences are less robust for naming than for LDT or sentence reading. This may be because isolated word naming relies less on lexical processing than the other two tasks. Whether naming responses are produced lexically, or by strict grapheme-phoneme correspondence rules, will depend on the proportion of spelling-sound regular and irregular words in the stimulus list. We demonstrate the influence of stimulus list structure on naming by comparing data from the Seidenberg and Waters (1989) Mega Study with data from smaller studies. For tasks which demand more lexical processing, such as LDT, we demonstrate that the influence of stimulus structure will depend on the disparity between lexical knowledge and local information obtained from the stimulus list. Stimulus list structure is most influential when it gives little, or no, reflection of real lexical experience.

Abstract:

The thesis took the general question of responsive curriculum development which meets both the needs of work and those of the academy as its starting point. The rationale for the topic flows out of education policy and societal pressures worldwide which are calling for an ever greater responsiveness from higher education to the workplace in the twenty-first century. Responsiveness to work requires collaborative and integrative work between communities of academic and non-academic practitioners. Differences between knowledge and practices at work and within the academy are broadly acknowledged in the literature, yet the ensuing nature and complexity of interactions between these two communities in curriculum design on the ground is poorly understood. A key point is to recognize that integration as such cannot be the goal
the differences remain, but have to turned into productive collaboration and joint development, for example, of a curriculum.

Abstract:
Perceptual processes take time to unfold. Whether a person is processing a visual scene, identifying the category an object belongs to, or recognizing a word, cognitive processes involving competition across time occur. These ongoing competitive processes have been ignored in studies of learning. However, some forms of learning suggest that learning could occur while competition is ongoing, resulting in the formation of mappings involving the competing representations. This dissertation uses word learning as a test case to determine whether such learning exists. In a series of five experiments, participants were taught words under different stimulus and task conditions to encourage or discourage learning during periods of lexical competition. These studies reveal a complex relationship between ongoing lexical competition processes and word learning. Specifically, in cases where learners rely on unsupervised associative learning, they present evidence of learning that is continuous in time, starting during periods of lexical competition and continuing throughout the course of its resolution. These studies offer insight into the nature of associative learning, into the forms of learning that occur when learning new words, and into the ways that task and stimulus structure impinge on how a learner forms new associations.

This study evaluated the difficulty, in terms of usability, of upgrading from one version of a word processor user interface (Microsoft Word 2003) to another (2007). Laboratory-based usability testing involving 23 participants, who had never used Microsoft Word 2007 before, was conducted. All participants used the two versions in a repeated-measures experimental design. A Tobii 1750 Eye Tracker was used for screen recordings during testing. Participants were also required to fill in user satisfaction questionnaires. Results from the usability test showed that, in terms of usability, migrating from an original interface to a completely changed user interface is not easy.

Abstract:

Systems that efficiently provide support for adaptive work processes in a mobile environment do not exist according to our knowledge. Such systems would increase efficiency and safety in environments where work is inherently mobile, ad-hoc, and requires input from a set of heterogeneous sources. Traditional work support systems are normally not capable of dynamic change and plans must be made before work is started. This conflicts with most work processes, which are dynamic and where plans cannot be completely pre-defined. Current workflow systems are for the most part not capable of handling dynamic change in the workflow process execution. Those that do exist are geared more towards long-term adaptability of the workflow process and not towards in-situ planning of activities. In this report we provide an overview over current research related to adaptive workflow, activity theory, situated actions, and context-awareness. Then, we further explore the concept of adaptive workflow and context-awareness and how this can be implemented in a prototype workflow enactment service. A set of requirements for such a system is elicited from this exploration. We also provide a possible scenario for usage of adaptive context-aware workflow technology. From these requirements we have created an overall architecture that supports adaptive context-aware mobile work. Our focus within this architecture is on context-aware adaptive workflow systems. We finally present the design and implementation of a prototype application supporting context-aware adaptive mobile work processes. This prototype has been named PocketFlow and is implemented in embedded visual C++ for Microsoft PocketPC 2003 second edition.

Abstract:
Children with cochlear implants (CIs) typically have smaller lexicons in relation to their same-age hearing peers. There is also evidence that children with CIs show slower rates of vocabulary growth compared to hearing children. To understand why children with CIs have smaller vocabularies, we proposed to investigate their word learning process and determine how it compares to children with normal hearing. The present study explores multiple aspects of word learning - acquisition, extension, and retention - to better inform us about the real-world process of lexical acquisition in children with CIs. We evaluated 24 children with cochlear implants, 24 children with normal hearing matched by chronological age, and 23 children with normal hearing who were matched by vocabulary size. Participants were trained and tested on a word learning task that incorporated fast mapping, word extension, and word retention over two days. We also administered a battery of tests that included measures of receptive vocabulary and speech perception skills to determine which variables might be significant predictors of fast mapping and word retention. Children with CIs performed more poorly on word learning measures compared to their age-mates, but similarly to their vocabulary-mates. These findings indicate that children with CIs experience a reduced ability to initially form word-referent pairs, as well as extend and retain these pairs over time, in relation to their same-age hearing peers. Additionally, hearing age-mates and vocabulary-mates showed enhancement in their production of novel words over time, while the CI group maintained performance. Thus, children with CIs may not take the same route in learning new words as typically-developing children. These results could help explain, in part, why this population consistently demonstrates slower rates of vocabulary learning over time. Furthermore, we expected that speech perception and vocabulary size would relate to variations in fast mapping, as well as word retention. Neither of these variables proved to be significant predictors of fast mapping, but they were highly significant for word retention. Based on these findings, we may conclude that the factors that account for acquiring that first link between a word and its referent are not the same as those that are important for storing in a word in long-term memory.

The study addressed the process of working people, called "pickers" who collect recyclable materials, particularly scrap of cardboard. The work done by the collectors of scrap cardboard occupies a central place in the lives of those who perform it, because, besides being a means of survival, is also a means of social integration, which enables the relationship between people and the feeling of belonging to a group. The survey was conducted in the South Zone, encompassing the city center of Manaus, where we selected three combinations (ALLIANCE, AND ECO-RECICLA ARPA) that work exclusively with scavenging scraps of cardboard. The process of industrialization in the Industrial Pole of Manaus and local businesses not only contribute to environmental degradation but also to the emergence of new social categories such as professional scavengers of cardboard. For this work, we understand that the city of Manaus there is a significant amount of leftover scraps of cardboard, where scavengers bound associations collect this material, so we need is to understand how this process works today and how the process of work done by these social actors. The aim of this study was to delineate the living conditions and talk through the characterization work processes carried out by scavengers of cardboard from Manaus-AM. The methodology used in this study was an exploratory qualitative research, through the forms, interviews, participant observation, oral history and geospatial technologies. According to results it was found that there is a small number of women on the streets picking up cardboard, they prefer to separate the material for recycling, organizing the sale and attend meetings representing the associations. The survey showed that 20% of the pickers had never attended school and other 70.0% responded that they have incomplete primary education and only 10.0% completed high school. Of the total number of collectors only 25.0% were born in the city of Manaus, while 75.0% were born elsewhere. About 85.0% of the collectors who own their own homes while 15.0% live in rented accommodation. According to the survey, despite the disease - especially the skin - they are very common among most collectors of cardboard, they do not link to their health, not binding them to the status of their work. Regarding the problem of alcoholism among collectors of cardboard, the survey data showed that 64.28% of respondents said that there are problems with alcohol and 28.5% said no. Regarding the working day was found to range from 9 to 15 hours weekly. As for monthly income, these range from £ 540.00 to 1.080.00, while the monthly average is $ 810.00. In the city of Manaus scavenging cardboard is held mainly by associations (Alliance, Arpa, Eco-Recycle) of reusable and recyclable, the workers perform the recycling collection service, material separation, pressing and baling of cardboard in different sizes . Although present in summary form. These actors begin their work scavenging material in the streets of inner cities and gather in the courtyards of the industries, after the selection process, this material is separated, weighed, pressed and finally tied it with bales of different sizes to marketing . The definition of collection sites has been established for many years, there are cases of scavengers collecting cardboard for 10 or 17 years, the center part of the routine of many collectors. Therefore, the space occupied, the area becomes a reference for the collector belonging. We can say it was an odd experience, to study the working process of the cardboard collectors in the city of Manaus, and see it through the eyes of a researcher, the situation of these social actors, as they enjoy what they do, we also found the possibility for change and solutions for the best development work. Also, realize that the work done by the collectors of cardboard are fundamental to the promotion of recycling and, consequently, to build a world natural and ecologically healthy, as it brings environmental benefits by saving natural resources, energy and water, beyond the undoubted environmental aspect.
O estudo abordou o processo de trabalho das pessoas, denominado de catadores que coletam materiais recicláveis, em especial, aparas de papelão. O trabalho realizado pelos catadores de aparas de papelão ocupa um lugar central na vida dos que o realizam, pois, além de ser um meio de sobrevivência, também é um meio de integração social, que possibilita o relacionamento entre pessoas e o sentimento de pertencer a um grupo. A pesquisa foi realizada na Zona Sul, englobando o centro da cidade de Manaus, onde foram selecionadas três associações (ALIANÇA, ECO-RECICLA E ARPA) que trabalham exclusivamente com a catação das aparas de papelão. O processo de industrialização no Polo Industrial de Manaus e comércio local contribuem não apenas para a degradação do ambiente, mas também para o surgimento de novas categorias sociais tais como as profissões dos catadores de papelão. Para a realização deste trabalho, entendemos que na cidade de Manaus existe uma quantidade significativa de sobras de aparas de papelão, onde catadores vinculados as associações coletam este materiais, assim precisamos é entender como esse processo funciona atualmente e como o processo de trabalho realizado por esses atores sociais. O objetivo desta pesquisa foi delinear as condições de vida e discorrer através da caracterização os processos de trabalho realizados pelos catadores de papelão da cidade de Manaus-AM. A metodologia utilizada, neste estudo foi investigação de caráter exploratório qualitativo, por meio dos formulários, entrevistas, observação participante, história oral e técnicas de geoprocessamento. De acordo com resultados verificaram-se que existe um número pequeno de mulheres nas ruas catando papelão, elas preferem separar o material para reciclagem, organizam a venda e participam das reuniões representando as associações. A pesquisa mostrou que 20% dos catadores nunca estudaram e outros 70,0% responderam que têm o ensino fundamental incompleto e apenas 10,0% concluíram o ensino médio. Do total de catadores apenas 25,0% são naturais da cidade de Manaus, enquanto que 75,0% nasceram em outras localidades. Cerca de 85,0% dos catadores possuem casa própria enquanto que 15,0% moram em casa alugada. Segundo os dados da pesquisa, apesar das doenças principalmente as de pele serem muito frequentes entre a maioria dos catadores de papelão, eles não a relacionam à sua saúde, não as vinculam à condição do seu trabalho. Com relação ao problema de alcoolismo entre os catadores de papelão, os dados da pesquisa demonstraram que 64,28% dos entrevistados afirmaram que existem problemas de alcoolismo e 28,5% disseram que não. Em relação à jornada de trabalho foi verificado que varia entre 9 a 15 horas, semanalmente. Quanto aos rendimentos mensais, estes oscilam entre R$ 540,00 a R$ 1.080,00, embora a média mensal seja de R$ 810,00. Na cidade de Manaus a catação do papelão é realiza principalmente pelas associações (Aliança, Arpa, Eco-Recicla) de materiais reutilizáveis e recicláveis, os trabalhadores da reciclagem realizam o serviço de coleta, separação do material, prensagem e o enfardamento do papelão em diferentes tamanhos. Apesar de apresentar de forma sumária. Esses atores iniciam seu trabalho com a catação do material nas ruas dos centros da cidade e o recolhimento nos pátios das indústrias, depois do processo de seleção, esse material é separado, pesado, prensado e por fim é amarrado por fardos de diferentes tamanhos até a comercialização. A definição dos locais de coleta foi estabelecida há muitos anos, existem casos de catadores que coletam papelão há 10 ou 17 anos, o centro que faz parte da rotina de muitos catadores. Portanto, o espaço ocupado, o território torna-se para o catador um referencial pertencimento. Podemos dizer que foi uma experiência impar, estudar os processo de trabalho dos catadores de papelão da cidade de Manaus, e vê-lo com os olhos de uma pesquisadora, a situação desses atores sociais, no que fazem gostam do que faz, verificamos também a possibilidade de mudança e soluções para o melhor desenvolvimento do trabalho. Além disso, percebemos que os trabalhos realizados pelos catadores de papelão são fundamentais para a promoção da reciclagem e, consequentemente, para a construção de um mundo natural e ecologicamente mais saudável, pois, trás benefícios ambientais através da economia de recursos naturais, energia e água, além do inquestionável aspecto ambiental.

Abstract:

In both the chemical and mechanical pulping process, the logs are cut into wood chips by a disc chipper before fibre separation. To make the wood chipping process more efficient, one have to investigate in detail the coupling between theprocess parameters and the quality of the chips. The objective of this thesis is to obtain an understanding of the fundamental mechanisms behind the creation of wood chips. Both experimental and analytical/numerical approaches have been taken inthis work. The experimental investigations were performed with an in‐house developed equipment and a digital speckle photography equipment. The results from the experimental investigation showed that the friction between the log and chipping tool is probably one crucal factor for the chip formation. Further more it was found that the indentation process is approximately self‐similar, and that the stress field over the entire crack‐plane is critical for chip creation. The developed analytical model predicts the normal and shear strain distribution. The analytical distributions are in reasonable agreement with the corresponding distributions obtained from a finite element analysis.

Esta dissertação trata sobre as modificações que o trabalho vem sofrendo a partir do processo de reestruturação produtiva praticado no Brasil desde a década de 1990, visando compreender melhor as alterações em curso, especialmente no que se refere às novas gestões empresariais baseadas em processos. Neste sentido, buscou conhecer a gestão por processos e sua relação com a organização do trabalho, tomando como exemplo uma empresa do setor elétrico brasileiro. Ressalta-se que tal modelo de gestão teve início, no setor, em 2012, com a reorganização da estrutura empresarial, desde a área de negócios até a gestão de recursos humanos. A pesquisa buscou analisar, também, a chamada reestatização do setor elétrico, associada a um movimento de aceleração do crescimento incrementada por exigências de competências e adventos tecnológicos, dada a sua posição estratégica para a economia e o acesso à energia pelos brasileiros. Da mesma forma, objetivou investigar a mobilidade gerada pelo modelo de gestão de processos, imposta aos trabalhadores, enquanto possibilidade de trabalho precário ou trabalho decente. A abordagem teórico-metodológica adotada pautou-se no conceito de trabalho decente como o direito a ter trabalho e de mantê-lo com dignidade e proteção social, tomando-se o trabalho precário como contraposição ao trabalho decente, isto é, como aquele que promove a redução ou suspensão dos direitos. Para tanto, foram realizados contatos com os gestores e com os trabalhadores da empresa estudada, de forma a se compreender a possibilidade de existência do trabalho decente em meio a uma mudança nos padrões de produção e organização do trabalho, onde a palavra de ordem é otimização, uma vez que a implementação da gestão por processos significa a possibilidade de tornar a empresa mais competitiva no mercado, através da otimização de custos e consequente aumento da eficiência na produção de energia elétrica. Os resultados da pesquisa indicaram que a empresa vem operando profundas modificações para atender às exigências do mercado, de forma ágil. Com isso, verificou-se uma diminuição considerável de gastos, principalmente na área de pessoal, com promoção de cortes no orçamento, desenvolvendo, dessa forma, um plano de incentivo à demissão de funcionários terceirizados, o que torna o trabalho decente uma possibilidade ainda distante de se realizar.
This dissertation discusses the changes that work has suffered since the restructuring process practiced in Brazil since the 1990s, intending to understand better the transformations underway, especially those which are related to new corporate managements based processes. The research sought to understand business process management and its relation to the organization of work, through the case study of a Brazilian public electrical company. It is worth emphasizing that this management model started in this sector in 2012 with the reorganization of the company structure, from the business departments to human resource management. The research also sought to analyze the so-called renationalization of the electricity sector associated with accelerating growth by increased demands for skills and technological advances, due to the strategic position of the economy and the access to energy for Brazilians. Equally, we aimed to investigate the mobility generated by this business process management model, imposed on work, and on those who only need their work to survive, through precarious or decent work. The methodological approach adopted was based on the concept of decent work as the right to work with dignity and social protection, seeing precarious work as the opposite of decent work, in other words, as one that promotes the reduction or suspension of rights. With this objective contacts were made with the managers and workers of the company studied in order to understand the possible existence of decent work during the changes in patterns of production and organization of work, where the buzzword is optimization, as the implementation of process management means the ability to make the company more competitive in the market, by optimizing costs and consequently increasing efficiency in electricity production. The research results indicated that the company carries out profound transformations in order to attend to market requirements in an agile way. With this, a considerable decrease in spending mainly in personnel was clear, with promotion of spending cuts, developing, a plan which incentivized the redundancy of outsourced workers, making decent work a distant dream to be achieved.

Thesis (M.A. (Mathematics Education)) --University of Limpopo, 2013
This study intended to improve Grade 9 learners’ mathematical processes of solving word problems. It was an action research study in my own classroom consisting of 64 Grade 9 learners. Learners were given learning activities on word problems to carry out as part of their normal classroom mathematics’ lessons. Data were collected in two stages: first, through passive observation, that is, without my intervention, and later through participant observation thus provoking their thinking as they attempt the given questions. The learners’ responses were analyzed through checking the mathematical processes they used without my intervention. Learners also submitted their post-intervention responses for analysis of progress after interventions. The scripts were reviewed based on four problem- solving stages adopted from George Polya (1945). Those stages are, namely understanding the problem, devising the plan, carrying out the plan and looking back. It became evident from the findings that learners attempt solving word problems with no understanding. Communication, reasoning and recording processes appear to be key factors in assisting learners to make sense of word problems and, finally, proceeding towards an adequate solution.

Abstract:

Den här studien har tagit sin utgångspunkt i vårt intresse för hur kunskaper som ele-verna kan ha nytta för i sin vardag, kan vävas in i skolans verksamhet. Dagens sam-hälle efterfrågar människor med både en förmåga att samarbeta med andra såväl som förmåga att lösa problem. Det krävs även att du ska ta ställning till olika val i många sammanhang. Syftet med den här studien är att undersöka hur och i vilken grad elever i årskurs tre samarbetar när de löser en vardagsanknuten problemlösningsuppgift samt hur elevernas problemlösningsprocess ser ut. För att få svar på studiens syfte har vi genomfört en empirisk undersökning med en kvalitativ ansats. Eleverna blev tilldela-de en vardagsanknuten problemlösningsuppgift att lösa i mindre grupper, med hjälp av ljudinspelningar och observationer har sedan elevernas samarbete och problemlös-ningsprocess studerats. Resultatet visade att det inte förekom så mycket samarbete mellan alla elever, samt att alla grupper kommit en bit på väg i problemlösningspro-cessen, Det som framförallt utmärkte sig var att ingen av grupperna hade uppnått den fasen i problemlösningsprocessen som berör reflektion och utvärdering av lösningen på problemet. Den största slutsatsen som dragits av den här studien, var att samarbetet fungerade olika i grupperna samt att eleverna ännu inte uppnått nivån som handlar om reflektion och utvärdering i problemlösningsprocessen.


This study has taken as its startingpoint in our interest for how knowledge that the students can have use for in their everyday life can be intervowen in the everyday work of the school. The society today asks for people with both an ability to cooperate with others and an ability to solve problems. It is also demanded that you take into consideration various choices in many circumstances. The purpose of this study is to investigate how students in third grade cooperate when they solve an everyday problemsolving task, and how their process of solving problem appears. We have conducted an empiric study with a qualitative approach. The students solved an everyday problem in small groups. By help of audio recordings and observations, the cooperation and the students’ process of solving problems has been studied. The results showed not much cooperation between all students, and that the students had reached different levels in the processe of solving problems. The major conclusion drawn of this study was that the cooperation between the students worked in different ways and that the students not yet had reached the level of reflecion and evaluation in the process of solving problems.

Abstract:

Signifikant Svenska AB supplies an information system called Assert, developed to facilitate the aftermarket sales in the manufacturing and subcontractor domains. The information system offers companies and organizations the possibility to gather their product information in a joint database in order to increase the information availability and distribution.

The management of the documents is an important part of the customer need and can be improved in order to also support document maintenance directly in Assert. At the moment, users only have the possibility to add and view documents in the database. By also providing users the possibility to create documents, update document contents, effectively reuse document sections and ease the translation of documents within Assert, the document management will be better facilitated.

The purpose of this thesis is to develop a prototype which shows the concept and benefits when providing the possibility to share document contents between several documents. The prototype is developed in C#/WPF and provides a word processor with features to reuse document contents and translation management.

Abstract:
The central purpose of this thesis is to study the familiar processes of quantum information theory from a thermodynamic point of view. Chapter 1 introduces equilibrium thermodynamics and its laws. The laws are then motivated in a statistical mechanics approach which explicitly employs the language of quantum information theory. Chapter 2 is dedicated to the concept of work extraction, in particular in non- equilibrium scenarios. In this context a generalised notion of equilibrium called passivity is introduced. The chapter's final section gives an introduction and an overview of various approaches to work extraction ranging from classical to explicitly quantum scenarios. Chapter 3 considers the question of powerful unitary operations. Focussing on the case of qubits (or rather wits, short for 'work bits') the chapter's first result is an explicit protocol for maximally powerful driving for any given initial state. Building onto this, the chapter's second main result is a proof that the evolution time (and hence the power of the corresponding work deposition process) can be decreased by a factor of 1/N for an array of N wits if global driving is permitted (rather than individual driving in parallel). Lastly, the thermodynamics of completely-positive and trace-preserving (CPTP) maps is considered in Chapter 4. It is shown that the energy change during such a process can be split into three parts: a work-like equilibrium contribution, a heat-like equilibrium contribution, and a third genuinely non-equilibrium energy difference. All three terms obtain their meaning when considering how much work can be extracted from the input and output state of the CPTP process, respectively. Furthermore, the identification of work and heat in this manner complies with a recently published version of the second law, which applies to the same class of processes. This is demonstrated by considering unital and thermal maps.

TCP's burstiness is usually regarded as harmful, or at best, inconvenient. Instead, this thesis suggests a new perspective and examines whether TCP's burstiness is useful for certain applications. It claims that burstiness can be harnessed to insulate traffic from packet reordering caused by route change. We introduce the use of flowlets, a new abstraction for a burst of packets from a particular flow followed by an idle interval. We apply flowlets to the routing of traffic along multiple paths and develop a scheme using flowlet-switching to split traffic across multiple parallel paths. Flowlet switching is an ideal technique for load balancing traffic across multiple paths as it achieves the accuracy of packet-switching and the robustness to packet reordering of flow-switching. This research evaluates the accuracy, simplicity, overhead and robustness to reordering flowlet switching entails. Using a combination of trace analysis and network simulation, we demonstrate the feasibility of implementing flowlet-based switching.

Partindo da hipótese de que um novo perfil foi configurado a partir dessas transformações, esta pesquisa tem o objetivo de conhecer o jornalista que trabalha hoje no Estado de São Paulo. O binômio comunicação e trabalho, a partir da abordagem ergológica, ou seja, de atividade humana, foi o referencial teórico utilizado, em que o sujeito revela-se como foco principal para este estudo. Como metodologia, foi adotada uma combinação de métodos quantitativos e qualitativos aplicados junto a três grupos de amostras: com jornalistas jovens, convocados a partir de redes sociais; com associados do Sindicato dos Jornalistas do Estado de São Paulo; e com jornalistas da Editora Abril. A amostra foi organizada no sentido de mapear a diversidade de jornalistas atuando hoje no mercado de trabalho em São Paulo, Estado que mantém aproximadamente 31% dos jornalistas brasileiros. Para obtenção de dados optou-se pelo uso de questionário eletrônico via internet e pela utilização de um roteiro de perguntas abertas para entrevistas em profundidade. A pesquisa observou que os jornalistas são jovens e individualistas; que estão trabalhando em condições precárias, como freelancers, PJs e autônomos. Além disso, a maior parte dos profissionais não está trabalhando nas redações: está atuando em diversas outras empresas, exercendo a função de assessor de comunicação.
The technological, cultural and interpersonal transformations occurred in the twentieth century have changed the communication companies, the relationship of society with information, and the methods and work processes of communication professionals. Assuming that a new profile was set from these transformations, this research aims to know the journalist who now works in São Paulo. The binomial communication and work, from the ergologic approach, in other words, of human activity, was the theoretical framework in which the subject is revealed as the main focus for this study. As a methodology, was used a combination of qualitative and quantitative methods applied with three groups of samples: with young journalists, called from social networks; with members of the Syndicate of Journalists of the State of São Paulo; and with journalists from Editora Abril. The sample was organized in order to map the diversity of journalists working today in the labor market of São Paulo, state which stands approximately 31% of Brazilian journalists. To obtain the research data we opted to use both: electronic questionnaire via Internet and a script of general questions in order to do in-depth interviews. The research noted that the journalists are young and individualists and work in precarious way conditions as freelancers, juristic person, and self-employed. Moreover, most professionals are not working in newsrooms: is working on several other companies, functioning as communications adviser.

A humanização é uma política transversal de todo Sistema Único de Saúde que pretende integrar os diferentes níveis de atenção. Sem um trabalho em rede não pode haver humanização. O elo fraco dessa rede quanto à humanização é o nível secundário de atenção. Este estudo objetiva justamente entender a humanização na atenção secundária como serviço de atendimento e como processo de trabalho em rede. Para tanto, foram entrevistados 10 profissionais de diferentes especialidades atuantes no ambulatório da Universidade Católica de Pelotas. Os resultados comprovaram que a atenção secundária como serviço, caracteriza-se como fragmentada e desarticulada da atenção básica e da atenção hospitalar, apesar de ser considerada como elo fundamental dentro do sistema de saúde. Além disso, a atenção secundária como processo de trabalho tem característica hospitalocêntrica, enfatizando o tecnicismo e a hierarquização, dificultando uma atenção à saúde concebida como um todo. Fica evidente a importância de uma visão sistêmica de saú
Humanization is a cross-cutting policy of all National Health System that aims to integrate the different levels of care. Without a networking can not be humanization.The weak link of this network about humanization is the secondary level of care. This study aims to understand precisely the humanization in secondary care and customer service, and as a process of networking. For this, we interviewed 10 professionals from different specialties working in the clinic of the Catholic University of Pelotas. Results showed that secondary care as a service is characterized as fragmented and disjointed from primary care and hospital care, despite being regarded as key link in the health system. Furthermore, secondary care as work process has a hospital-feature, emphasizing the technical nature and hierarchy, making hard a health care designed as a whole. It is evident the importance of a systemic view of health and the need for changes in work processes.

Abstract:
This research investigated the relationships between involvement-oriented human resource practices and work outcomes, mediated by high involvement work processes. The goal was to use an involvement framework - comprised of the elements of power, information, rewards, knowledge, and a fifth element developed for this thesis, integration - to select human resource practices that impact on work outcomes, and to develop an understanding of intervening involvement processes. Data was collected from 200 work groups in a public sector organization of 4,300 employees, engaged in large infrastructure projects, including bridge and road construction and maintenance. Group-levels of human resource practice implementation were collected through surveying a sample of employees from each work group. Data on work outcomes and high involvement work processes were collected three months later through an organizational survey of all 4,300 employees. This process was repeated 12 months later to identify the unique effects of human resource practices and investigate causal relationships and lagged effects. Involvement-oriented human resource practices were found to impact significantly on work outcomes. High involvement work processes explained significant variance in outcomes and mediated the relationship between HR practices and outcomes. Longitudinal analyses supported the existence of lagged effects of involvement-oriented human resource practices on high involvement work processes, and high involvement work processes on work outcomes. The research supports the utility of an involvement framework for practice selection and for explaining mediating processes on work outcomes.

Abstract:
Word recognition techniques are reviewed. An exhaustive comparative study of many of the factors that affect recognition accuracy is presented. Experiments centred on four major areas of word recognition are described: pre-processing techniques, recognition features, recognition algorithms and distance measures. Recognition accuracy, in the context of each of these four areas, is investigated using the digit vocabulary spoken by 10 New Zealand (6 male and 4 female) and 38 American (20 male and 18 female) speakers. Pre-processing techniques examined are the type of window, the length of the data name, data frame overlap, and pre-emphasis. Acoustic features tested include temporal features such as energy and zero-crossing rate, as well as frequency based acoustic representations such as linear prediction coefficients, cepstral coefficients, dynamic (transitional) cepstral coefficients, and perceptual linear prediction coefficients. Three types of distance measures are also reported on the Euclidean, the weighted Euclidean, and the projection. Two methods of training, random template selection and clustering, are investigated. Accuracy improvement by combining different features is also examined. Implementation of a real-time word recognition system designed on the basis of the comparative study and experiments, is described. The system is based on a TMS320C30 and takes around 0.03 seconds per recognition. The real-time system achieves speaker-dependent accuracies greater than 95% and speaker-independent accuracies greater than 70% for the digit vocabulary. An examination is also made of two methods of continuous recognition using sub-word representations. Both these methods take advantage of isolated word recognition techniques such as dynamic programming. A segmentation method and anon-segmentation method were investigated. Accuracy of the segmentation recognition method is found to depend linearly on the accuracy of the segmenter. With a segmentation error of 22%, an average recognition accuracy of 90.7% was obtained for 10 vowels and 2 consonants. For the non-segmentation recognition method, an average accuracy of 75% was obtained. Although the segmentation method produced higher accuracies than the non-segmentation method, it is argued that the removal of the segmentation is an advantage that greatly simplifies the recognition strategy.
