Full textAbstract:
This work deals with the design and implementation of a hardware unit that is capable of playing MPEG-1 Layer III files, compliant with ISO/IEC 11172-3. There are given the benefits of using the MP3 format and principles that make it possible to compress the size of the resulting music recordings. The file format and all parts of the header are thoroughly studied as well as the method of encoding information. The process of the data decoding is divided into several consecutive, more or less discrete functional units and these units are designed and described in a hardware description language VHDL. There are also discussed features of FPGA chips - programmable gate arrays. Those are used for physical realization of the MP3 player. A development board is selected, including such an FPGA chip and other resources that allow synthesis of the entire circuit and playback in real time.

Resumo: Neste trabalho se propôs a utilização do MP3 player portátil para gravação de sinal nãoáudio em sua memória, utilizando-se seu recurso para gravação de voz. Para avaliar a proposta, retirou-se o microfone de eletreto do MP3 player e em seu lugar injetou-se um sinal de FM, com portadora de áudio de 1200 Hz modulada pelo sinal de interesse. O sinal é gravado no aparelho em arquivo no formato WAV. Sua recuperação se fez usando um demodulador de FM a PLL cuja entrada é o sinal de FM captado nos terminais da bobina do fone de ouvido do MP3 player. Nos testes, usou-se sinal senoidal e sinal de eletrocardiograma. Embora a qualidade dos sinais de baixa freqüência precise ser melhorada, em geral os resultados apontam para a viabilidade da proposta. Fazem-se sugestões para melhorias e extensões do trabalho.Abstract: This work proposes the use of portable MP3 player for recording non-audio signal in its flash memory, by means of its voice recording function. To evaluate the proposal, a 1200-Hz FM carrier modulated by the signal of interest replaced its electrete microphone signal. The FM signal is saved in the instrument in a WAV file. The signal recovery was made using a PLL-based FM demodulator whose input is the FM signal captured in the coil leads of the MP3 player's earphone. The tests used sinusoidal signal and eletrocardiogram signal. Although the quality of low frequency signal needs improvement, overall the results indicate the viability of the proposal. Suggestions are made for improvements and extensions of the work.

Cette thèse relève de la didactique de l’anglais. Il s’agit d’une étude exploratoire des représentations et attitudes de 170 lycéens, relative à l’introduction et l’utilisation du baladeur MP3 en cours d’anglais. Notre démarche d’investigation a reposé sur une approche systémique de la situation d’apprentissage. Afin de mettre au jour l’attitude des apprenants, nous avons utilisé des questionnaires. Nos résultats ont mis en évidence l’absence d’unanimité dans l’acceptation du baladeur MP3 en cours d’anglais. Une utilisation régulière du baladeur MP3 dans la vie quotidienne ne prédispose pas à son appropriation dans un contexte scolaire. Le baladeur MP3 n’est pas un objet réel – c’est un artefact qui se reconstruit selon les usages. Notre étude a également montré que les représentations de l’objet technologique chez les apprenants dépendaient de leurs représentations des autres éléments de la situation d’apprentissageThis PhD thesis concerns the learning/teaching of the English language. It consists in an exploratory study of 170 high school students’ beliefs and attitudes as regards the introduction and use of an MP3 player in English classes. Our investigation was based on a systemic approach of the learning context. In order to expose the learners’ attitude, we used questionnaires. Our results highlighted the absence of consensus in the acceptation of the MP3 player in English classes. A frequent use of the MP3 player in the daily life does not involve its appropriation in a school context. The MP3 player is not a real object – it is an artefact that is reconstructed according to the uses. Our study also showed that the learners’ beliefs of the technological object depended on their beliefs of the other elements belonging to the learning context

Full textAbstract:
Since the introduction of the iPod in 2001, portable music listening devices that play or stream compressed music files have steadily become the standard devices used to listen to music. Despite this, few music education researchers have investigated the role that such devices have in shaping students' music listening experiences. This dissertation is meant to fill that gap in the literature and contribute to the existing sociological and psychological literature on music listening in everyday life.
Phenomenology served as the theoretical framework for the design of the study. 10 college students from three institutions underwent iterative interviews and were asked questions developed from McCarthy and Wright's (2004) Deweyan method for investigating user experiences with technology. The questions fell into five categories: sensual, emotional, compositional, spatio-temporal, and the sense-maker. The participants' responses were digitally recorded, transcribed, and analyzed using grounded theory methods. The following four axial codes emerged from the data and were used to divide the dissertation into chapters: "Embodying the Experience," "Organizing the Experience," "Navigating Real and Virtual Spaces," and "Developing the Self."
The main finding articulated in the chapter entitled "Embodying the Experience" is that the participants located the music in their heads while listening to music on their devices using headphones or earbuds. In contrast, participants consistently reported that, when listening to music through open-air speakers, they experienced the music as being located everywhere or in their whole bodies.
The main finding in the chapter entitled, "Organizing the Experience," is that participants exercised agency in their music listening experience by creating playlists. Typically, playlists were created by the participants to be used in conjunction with other activities such as exercising, studying, commuting, and so forth. I used these findings to develop the concept of "Integration in Consciousness" which models the participants' simultaneous engagement with the music and other activities.
In the chapter entitled "Navigating Real and Virtual Spaces," I explore how the participants simultaneously navigated the spatial aspects of the music listened to on their players and the spatial aspects of the physical spaces within which their activities naturally occurred. In doing so, I provide an example of how the participants experienced music and activities as "Integrated in Consciousness."
In chapter seven, "Developing the Self," I explore how the participants' uses of their devices reflect their development as adolescents. In addition, I propose that participants' uses of their devices may be constitutive of their adolescent development.
Finally, in chapter eight, I explore the ways in which music teachers can utilize the findings of this study in the development of their own classroom pedagogies. Among other things, I propose that music teachers can use the "Integration in Consciousness" model to help their students communicate about their music listening experiences in the classroom. In the use of this model, music teachers can tailor their pedagogies specifically for the technology rich, "post-performance" world within which they teach.

The use of portable listening devices (PLD), among teenagers, has grown and caused an increase in time exposure to high sound pressure levels. Is important to know the hearing habits of a group of young people from a private school and a public school in the city of São Paulo and to verify the level of awareness about the potential hearing damage caused by improper and prolonged exposure to high levels of loudness in recreational activities in order to promote good hearing habits. Objective: to investigate the hearing habits of teenagers from 14 to 18 years of age regarding to the use of portable listening devices, situations experienced after the use of devices and hearing loss prevention measures. Method: This is a cross-sectional study in a population of adolescents between 14 and18 years of age. The questionnaire used was based on a research conducted by Zogby et al. (2006). Method: the questionnarie was given by the researcher and answered by the students at home. The descriptive results analysis and association analysis were carried out through the chi- square and the Fisher s exact tests . Results: the sample was constituted by 86 students from 14 to 18 years old. The results show that more than 73,9% of the students , males and females, and of the two schools use music portable devices with earphones. In general, boys use the PLD in a higher volume, during more hours and many times during a week. The answer pattern for girls from public schools is similar to the boys from private schools. The general pattern for both boys and girls, shows that the higher volume comes in association to a major frequency of use. 60% of the students use computer/ laptop with earphones. 100% of the girls from public school use VI mobile phone with earphones, in private schools we found 60% for girls and 72,6 % for boys. Girls are more inclined to reduce the time of using and the volume of the PLD. 50% frequent parties /shows / samba school rehearsal. The hearing symptoms and extra-symptoms aren t different between males and females. The girls from private school, regarding to the public school, showed a minor interest in using hearing protection, and to know the influence of the sound pollution and to participate of hearing health. The students that use PLD / mobile phones showed more need in rising the volume of the TV/ radio, beside saying ham and feeling more tired. The boys that are inclined to use hearing protection, demonstrate worry concerning to lose hearing. Conclusion: The use of portable listening devices with earphones and mobile phones is a common habit among teenagers. Go to parties and shows are, at least, part of the daily life of the half of the analysed public. The interference of these facts in the hearing health of this population is already noticed by part of it. Although this behavior is settled among adolescents, we can see a tendency to a change of habits and a worry in losing the hearing datas that can benefit the implementation of hearing health at schools
O uso de dispositivos portáteis de música (DPM) entre adolescentes tem crescido e provocado aumento no tempo de exposição à elevados níveis de pressão sonora. É importante conhecer os hábitos auditivos e a forma como os adolescentes se comportam diante de situações ruidosas para verificar seu nível de consciência sobre os potenciais riscos auditivos e extra auditivos a que se expõem nas atividades de lazer. Objetivos: investigar os hábitos auditivos de adolescentes entre 14 e 18 anos de idade. Método: estudo transversal em uma população de adolescentes entre 14 e 18 anos de idade de uma escola particular e de uma escola pública da cidade de São Paulo. Foi utilizado um questionário sobre hábitos auditivos baseado na pesquisa de Zogby et al. (2006). O instrumento foi entregue pela pesquisadora e respondido em casa pelos alunos. Foi realizada análise descritiva dos resultados e análise de associação através dos testes quiquadrado e exatos de Fisher. Resultados: a amostra foi constituída por 86 estudantes com idade entre 14 e 18 anos. Os resultados mostram que mais de 73,9% dos alunos de ambos os sexos e das duas escolas usam dispositivos portáteis de música com fones de ouvido. Meninos geralmente utilizam os DPM em volume mais alto, por mais horas e várias vezes durante a semana. O padrão de respostas para as meninas da escola pública se assemelha ao dos meninos da escola particular. O padrão geral de respostas para ambos os sexos mostra que geralmente o volume mais alto vem IV associado a uma maior frequência de uso. 60% dos alunos utilizam computador / laptop com fones de ouvido. 100% das meninas da escola pública utilizam telefone celular com fones de ouvido, na escola particular encontramos 60% para as meninas e 72,6% dos meninos. As meninas são mais propensas a diminuir o tempo de uso e o volume dos DPM. 50% frequentam baladas / shows / ensaios de escola de samba. Os sintomas auditivos e extra-auditivos não diferem entre os sexos. As meninas da escola particular, em relação à escola pública, apresentaram menor interesse em utilizar proteção auditiva, conhecer a influência da poluição sonora e participar de programas de saúde auditiva. Os alunos que utilizam DPM / telefones celulares apresentaram maior necessidade de aumentar o volume da TV / rádio, apresentaram necessidade de falar ham e sentiram-se mais cansados. Os meninos que estão propensos a usar proteção auditiva apresentam preocupação em perder a audição. Conclusão: a utilização de dispositivos portáteis de música com fones de ouvido e de telefones celulares é um hábito generalizado entre os adolescentes. Frequentar baladas e shows também faz parte do cotidiano de pelo menos metade do público analisado. A interferência desses fatos na saúde auditiva dessa população já é notada por parte dela. Embora esse comportamento esteja arraigado entre os adolescentes, observa-se uma propensão à mudança de hábitos e uma preocupação em perder a audição dados que podem favorecer a implementação de programas de saúde auditiva nas escolas

In addition to the two present methods for programming mechanism of MP3 players, due to the marketing competition of MP3 players, there is a need for a fast GUI design for various customers. The first method stores only the boot code in the internal ROM of the controller chip which includes the initializing program code. The main program is stored in the NAND gate flash memory. As long as the initialization is completed, the main program will be loaded into the internal RAM of the controller chip from the NAND gate flash memory. The advantages of this method are that the main program can update the GUI anytime and provide more flexibility. However, the controller chip area will increase due to the need of internal RAM for loading the main program. The second method is to store the main program into the internal ROM of the controller chip, by which this design does not need to use an extra internal RAM of the controller chip in order to save the controller chip area. However, when the main program is once stored into the internal ROM of the controller chip, the function of the MP3 player can not change any more. In this paper, we propose a table based GUI design which provides a fast way to obtain the different programmable GUI from the pre-stored NAND gate flash memory. A couple of tables are used to support various customer GUIs, such as, a command table for the starting display procedure, a display table for the basic display components, a menu table for the basic function of the MP3 player and a button table for the button function used with the MP3 player operation. These tables can be pre-stored in the NAND gate flash memory. When users turn on the MP3 player, the main program in the internal ROM of the controller chip will load in the customer required tables from the NAND gate flash memory. Hence, by using our design, a different set of these tables will provide users with different GUIs even if the same chip set in the hardware modules is utilized.

This research investigates the shape of MP3 players with differential in users’ emotions. First, clarifies what emotion is and how emotions affect humans’ intent. Then compares with several experimental tools of user emotion in product design, which starts in visual point “pleasure”, and seeks for appropriate method into this study. This research discovers that “visual pleasure” could be weaken by time. How “user emotion” applies into products design can be related to personal culture background, experience and life style. In the buying motives of this questionnaire, the essential factors for consumers are function, price and brand. The first order motive is function>price>brand, then is price>function>brand. The population statistics and life style of this questionnaire are obvious different in 10 of the MP3 players. The statistics investigates 7 of user emotions with the shape of products all fall in the same line, which are desire、pleasant surprise、inspiration、amusement、admiration、satisfaction and fascination. The phenomenon explains user’ impression with the shape of product are partial to equal pleasure or unpleasure.

This paper includes two subjects. The first subject section is about how to design and implement an automatic testing system for MP3 players. We design a test program which includes several kinds of program code. For instance, the “function code table” provides the program of operation functions, the “picture code table” provides the picture display, the “transfer code table” provides the test module transformation, and the “button code table” provides the press button test and the test program which is stored with the main program of the MP3 player in the NAND Flash. When the operator turns the MP3 player on, the first flag decides whether the test program will go into “automatic test mode” or “normal mode”. When the first flag points at the automatic test mode, the MP3 player executes the test program from the NAND Flash. It also guides the operator in carrying out the tests, such as sound effects, OLED display, record module, line in module, lock and press button. In the second subject section is about how to design and implement an automatic testing system for digital photo frames. We extend the first sub-topic design concept to design a test program which is stored with the main program of the digital photo frame in the NAND Flash. When the operator turns the digital photo frame on, the first flag decides whether the test program will go into “automatic test mode” or “normal mode”. When the first flag points at the automatic test mode, the digital photo frame executes the test program from the NAND Flash. It also guides the operator in carrying out the tests, such as Compact Flash card, Memory Stick card, Secure Digital card, USB Flash Drive, press button, headphone, loudspeaker and sound effects test.

Product usability is one of the most significant concerns in the use of consumer electrical products. In the product development process, the product prototype is a common and useful tool for identifying product usability problems. The objectives of this study are to compare the efficiency and effectiveness between two different types of product prototypes (virtual and physical) on the identification of product usability problems, and to suggest the best application of these prototypes for future product development. In this study, eight hypotheses have been proposed and tested by using think aloud method. Results from this study indicate that the physical prototype is more efficient and effective than the virtual prototype for identifying the usability problems regarding to users’ feels about product exterior features and overall impression. However, the virtual is more effective than the physical prototype for identifying the usability problems in respect to users’ performance on interacting with the product. In is concluded that product designers should be aware of the effectiveness and efficiency of these two product prototypes for identifying two different types of usability problems. The possibility of integrating these two product prototypes is also addressed in this study.

This study investigated university students with different ideal self-concept types and their preferences and image on appearance of MP3 player. First, we used Malhotra’s self-concept scale to survey university students’ ideal self-concept and use main principal component analysis, cluster analysis, and Scheffe multiple comparison to sum up four ideal self types, followed with appearance image testing of MP3 players, and used regression analysis to explore the image that affects preferences of every ideal self-concept groups. Finally, we used Class I of Lin’s volume to analyze the preferences of every ideal self-concept group on the appearance features of MP3 players. The preferences of every ideal self-concept group on the appearance features and form images of MP3 players are as follows: 1 Elegant comfortable group: the form images of MP3 players impacted by their preferences are "vogue", "fashionable", "elegant", and the form features of the appearance are "no surface decoration," "thin-shaped", "small screen", "rectangle" "small surface area." 2. Simple and low-key group: the form images of MP3 players impacted by their preferences are "vogue", "light" and the form features of the appearance are "no surface decoration," "thin-shaped", "small surface area", "positive button", "square button." 3. Pure taste group: the form images of MP3 players impacted by their preferences are "vogue", "feminine" and the form features of the appearance are "no surface decoration," "small surface area", "small master keys," "Circular keys", "pressure-type button." 4. Sensible and steady group: the form images of MP3 players impacted by their preferences are "vogue", "avant-garde", "simple", and the form features of the appearance are "no surface decoration", "large surface area", "no screen", "square button", "pressure-type button."

Full textAbstract:
Over the last generation changes in the social structure of the family and children's command of an increasing share of family spending have led marketers to cultivate children as an important consumer demographic. The designation "tween," which one marketer refers to as kids "too old for Elmo but too young for Eminem," has become a catchall category that includes kids as young as four and as old as fifteen. Music marketed to children--led by the Disney juggernaut, which promotes superstar acts such as the Jonas Brothers and Hannah Montana/Miley Cyrus across television, radio, film, DVDs and CDs, and branded toys, clothing, and electronics--represents a rare "healthy" area of the music industry, whose growth has paralleled the expansion of portable media technologies throughout U.S. consumer culture. The increasing availability of portable media devices, along with the widespread installation of Internet terminals in schools and educators' turn toward corporate-produced "edutainment" for lessons, has reconfigured schools as central sites of children's media consumption. Off-brand MP3 players packaged with cheap and brightly colored earbuds have become more and more affordable, and marketers increasingly target kids with celebrity-branded music devices and innovations like Hasbro's iDog series of toy portable speakers, which fit naturally among children's colorful and interactive collections of toys. At the forefront of the "digital revolution, children are now active--even iconic--users of digital music technologies. This dissertation argues that tweens, as prominent consumers of ascendant music genres and media devices, represent a burgeoning counterpublic, whose expressions of solidarity and group affiliation are increasingly deferred to by mainstream artists and the entertainment industry. We appear to be witnessing the culmination of a process set in motion almost seventy years ago, when during the postwar period marketers experimented with promoting products directly to children, beginning to articulate children as a demographic identity group who might eventually claim independence and public autonomy for themselves. Through long-term ethnographic research at one small community of children at an elementary school in southern Vermont, this dissertation examines how these transformations in the commercial children's music and entertainment industry are revolutionizing they way children, their peers, and adults relate to one another in school. Headphones mediate face-to-face peer relationships, as children share their earbuds with friends and listen to music together while still participating in the dense overlap of talk, touch, and gesture in groups of peers. Kids treat MP3 players less like "technology" and more like "toys," domesticating them within traditional childhood material cultures already characterized by playful physical interaction and portable objects such as toys, trading cards, and dolls that can be shared, manipulated, and held close. And kids use digital music devices to expand their repertoires of communicative practices--like passing notes or whispering--that allow them to create and maintain connections with intimate friends beyond the reach of adults. Kids position the connections and interactions afforded by digital music listening as a direct challenge to the overarching goals around language and literacy that structure their experience of classroom education. Innovations in digital media and the new children's music industry furnish channels and repertoires through which kids express solidarity with other kids, with potentially transformative implications for the role and status of children's in their schools and communities.

How to make sure the public can feel free and comfortable when using the state of the art technology devices is the major subject to the product designer. According to the popularization of digital music and the decreasing price of MP3 player, the population of MP3 users is growing rapidly. However, there are only a few costumer-oriented-designed MP3 players which are designed for using easily or user friendly on the market now. This article will discuss the interface design for MP3 player in detail for developing handy devices. This article discussed by relative literature to realize MP3 player, analyze the present situation of MP3 player interface design, the functions and problems for using of MP3 player, and the usage environment relation, so that discuss one step ahead about the trend of design. According to questionnaire survey, we would like to find out the likes and dislikes to the interface design of each kind of MP3 players. On the side of human-computer interaction, this article collected and arranged related records written by international scholars papers and found out the concept of human-computer interaction which the designers should know and follow when they are working for a new era product. After integrated all bibliographies above, we analyzed from the cases of human-computer interaction and chose three outstanding cases of them. They are iPod, MOTOROKR E8, and wii. In this work, we would discuss the essential factors for success and the merits and the defects of functional interface for the basis to design and to draft a set of design rule for the users in the following section. At last, we would integrate the bibliographies and the results of analysis to introduce human-computer interaction into product design including the development feasibility of design to MP3 player and realized the operation process. In this thesis, we propose and build up four different design projects and present with 2D-drafting software and choice a project to develop a real product with practicability and convenient operation.

The object of this study is to verify the effectiveness of axiomatic design principles on the usability problem identification for consumer electronics products. An analysis according to axiomatic design principles and a usability test were conducted on a prototype of an MP3 player model. In the analysis, we use card sorting and cluster analysis methods to gather and group the data from the subjects for their cognition on the function requirements of the MP3 player. Then, the design parameters of the MP3 player were classified based on the control buttons and their functions. Finally, the possible usability problems were identified by applying the design matrix to analyze the mapping between the function requirements and the design parameters. In the usability test, the usability problems were identified through the observation of subjects’ operations with the MP3 player for fulfilling assigned tasks. A great consistency has been found between the results from the analysis and the results from the usability test. It is then concluded that the analysis with axiomatic design principles is an effective tool for the product usability problem identification.

In the field of technology and innovation management, innovation evolution historically has enjoyed high level of attention. The theories such as dominant design, technological guidepost have been used to describe the evolution nature of the innovations. However, various innovations still demonstrate developments outside the descriptions of existing theory. We hope to address this issue by conducting a data rich detailed longitudinal study on an innovation to see whether existing theories, more specifically the dominant design theory, can describe the evolution of the innovation. We collected detailed information (especially on product level) of the portable MP3 player innovation in U.S. between 1998 and 2012 from various secondary sources including industry magazines, popular press, and company websites. Using this information, we try to understand the convergence nature of the innovation and test whether the dominant design theory can explain the evolution of the innovation well or how it is different from the theory.

Regarding product design as a process of communication, businesses put design products into market, and through some marketing strategies they can only wait for consumer’s purchase decision. However, they do not know consumer’s response to product aesthetics during the communication process. Under this circumstance, a black-box stuck in the communication process. There is no way for businesses to know the reason that their product designs are popular or not. This study arranged in-depth interviews with 11 consumers who value aesthetic attribute of MP3 players and the interviews focused on their aesthetic response to MP3 players. Aesthetic response was described as three categories： 1. Aesthetic impression: the attributes of product appearance that consumers value include small-and-thin in look, simplicity, high quality in look, and uniqueness. 2. Semantic interpretation: out of aesthetic concern, consumers prefer less description in appearance. Attributes such as size, button, and look of product appearance may assist or constrain the use of MP3 players. 3. Symbolic association: consumers may communicate their identity through MP3 players. The association is divided into self-expressive and categorical meanings. The self-expressive symbolism associated with products is derived from personal preferred style, self- expecting image, and brand recognition. The categorical symbolism associated with products includes the association with acquaintances and brand image. Besides product itself, there are also other aspects of marketing strategies influence consumers’ aesthetic cognition. Thus, the influences that price, place, and brand awareness have on aesthetic response were also examined in this study.

The aim of this study is to investigate the usability of the operating interface of MP3 players in terms of the user mental model and to propose new models based on the results of the pilot test. This study first applied both the quantitative and qualitative approaches to analyze and compare users’ operating efficiency and feelings about MP3 players. Then, two novel, emulated MP3 player interfaces were developed according to results of the literature review and pilot test. A practical test, survey and interviews were conducted on these two interfaces to provide full-scaled research results as shown below. (1) The effect between operating efficiency and user preferences is indefinite. In the pilot tests, the operating efficiency of the iPod samples is lower than that of Sony, but the former has better subjective ratings. Also in the practical test, instead of interfaces with higher operating efficiency, users prefer interfaces with pleasant feelings, interactions and better visual effects. As such, it is clear that designers seeking to enhance the operating efficiency of MP3 players without considering the subjective views of consumers will be unable to fulfill the consumer preferences. Observations of this study also indicate that visual effects play a decisive role in user preferences, particularly the dynamic effect, iconic display design and color scheme, which are the essentials of user preferences. Therefore, it is recommended that MP3 player designers should add suitable dynamic effects to their products in order to help users establish a correct mental model of product operations and to increase the pleasant feelings of product use. (2) The effect of iconic interfaces is superior to tab interfaces. In the practical test, though the difference in operating efficiency between iconic and tab interfaces is insignificant, the difference is significant in the subject feelings of users between both types of interfaces in terms of user feelings, interaction, visual effect, structure expression, SUS usability and QUIS satisfaction. Therefore, menus presented in iconic interfaces (with text tips) impress users more than tab interfaces (with icon tips) and have better comments. Results of interviews indicate that if previews of items in the submenus are provided in the function menu in the first page, this can increase the confidence and trust of users in operating the interface. (3) The difference in the same emulated interface between young and old users is insignificant. This suggests that the interface design satisfying one user group will not bring trouble to another group according to this study; i.e. emulated interfaces have better comments in the young user group also have the better comments in the old user group.

MP3 compression format has been widely used in multimedia player and storage application for its convenient. It is an essential standard for digital audio compression nowadays. A MP3 player can implement different sampling rate in software or hardware design method. It is usually implemented in hardware design method especially for hand-held devices. It can be realized by adjusting the operating frequency of digital signal processing circuit. In addition, it will reduce the power consumption since the power consumption of digital circuit is proportional to operating frequency. In this thesis, the design of PLL-based frequency synthesizer for a digital signal processor (DSP) is described. It provides a programmable clock signal with variable frequency for DSP to operate in different condition. For higher speed and performance, a clock signal with higher frequency is used. For power saving requirement, a lower frequency clock signal is used. This circuit was fully integrated with a 0.18 μm 1P6M CMOS process. An 24 MHz crystal oscillator is used as a fundamental clock for this PLL. To generate the reference frequency for this PLL, a frequency divider is used to divide down the 24 MHz clock first. In addition, there includes a programmable frequency divider for frequency synthesizer. The frequency synthesizer is designed to generate a clock frequency from 31.059 MHz to 81.882 MHz. The supply voltage is 1.8 V with a ± 10% tolerance. The PLL has been tested and it can lock to all frequency range. The measured jitter is 85ps at 81.882 MHz, and the maximum current consumption is around 570uA.

In recent years, with the rapid development of technology, new consumer electronic products are continuously promoted to lead to high level of convenience and entertainment for people. However, the serious damage on the environment and resource waste during the process of production and waste should never be neglected. Since past studies tended to focus on product design and the manufacturing effect of meeting the environmental laws, instead of the influence of green products on 3R (Reduce, Reuse, Recycle) and green product effect according to consumer feedback, it is difficult to probe into the reasons of negative effects of products in the market and improve them. This research intends to study the influences of the consumers’ purchase and product use on 3R and construct MIR model upon consumer feedback. The research will divide the consumer into three typologies of green consumption by using cluster analysis. The consumers’ consideration of MP3 player purchase is analyzed by analysis hierarchy process (AHP) to find different influences of their consideration on 3R. According to the research finding, using MP3 player as an example, from the perspective of the consumers’ purchase, we find that in 3R, ”Reduce”, ”Reuse” are the most frequent whereas ”Recycle” is the aspect which should be improved.

ABSTRACT Considering the increasing demand for a wireless connection to a portable MP3 player, we propose the integration design of a MP3 Player with a Bluetooth hand-free/set. The Bluetooth module serves as the wireless channels between the MP3 player and wireless headphone, the wireless microphone and recording memory cards, the FM receiver, as well as the cellular phone. Audio switches in our design are used to facilitate the corresponding audio paths. We have chosen a highly integrated chip set to fulfill the required functions, resulting in less power consumption, and extension of the recharge cycle. In this integration design, we use a simple operational amplifier with a negative feedback circuit to suppress the common mode noise resulting from high frequency signal coupling between the audio paths. Overall, our prototype design has already demonstrated good sound quality for a wireless MP3 player.

As time evolves and technology advances, technology products are continually improved, which makes the product life cycle shortened and the price changes swiftly. This research takes one of the popular products, MP3 players, for example. The thesis analyzes the reasons affecting the price and which main factors influence the decision of pricing with distributor’s viewpoint. Through the research, we are capable of knowing the marketing information to decide the price of a product to make it more precisely. From the viewpoints of distributors, this research applies the transaction records to conduct empirical study and with the standpoints of distributors of technology products to analyze and discuss the issue. With the authentic transaction data, the researcher made a comparison regarding the levels and difference resulted from the related factors to set up the price as well as the variables that affect the price. To begin with, this research applies 1-way ANOVA to the relative price and divides the prices of MP3 into three level, i.e. high-priced level (high-priced and higher-priced levels), middle-priced level (higher-middle, middle, and lower-middle levels), low-priced level (low and lower-priced levels). Next, the research examines the relation between the price and eight independent variables with regression model. The eight independent variables are retailer grade, memory size of products, capacity/price , selling months, sales amount, unit cost, cost ratio, and gross margin. The empirical research reveals that the relation between retailer grade and selling price is not signification. Among the variables, the positive effect variables are memory capacity of products, capacity/price, unit cost, the rate of cost, and gross profit. The negative effect variables are duration of selling and sales volume. On the other hand, the researcher conducts the stepwise regression analysis. The chosen variables are the same as the seven distinct relative variables in regression model, but the critical one in affecting the price is unit cost. This research concludes that the unit cost is the priority factor for distributor to set up price.

High-technology products keep being innovated, while individual purchasing behaviors are different. The involvement theory reasonably explains why consumers do not always undertake a complex decision process requiring substantial amounts of time and energy while making a consumption decision. The study applied involvement to a high-technology product—MP3 player, combining and revising the involvement scales developed by Zaichkowsky(1985), Laurent and Kapferer(1985) and Mittal(1989) to measure consumers’ involvement. In addition, relevance between purchasing behaviors and purchasing types was examined, and consumers of various purchasing types based on involvement were profiled. The survey was conducted by Internet. After collecting the raw data, Factor Analysis was used to extract the constructs of involvement, and Cluster Analysis was conducted to sort the consumers into five types. They are Information Surfers, Comparison Shoppers, Fashion Chasers, Indifference Shoppers and Impulse Buyers. Different purchasing types represent different involvement levels. Then, Chi-Square Analysis was applied to examine the differences both in the purchasing behaviors and in the individual characteristics among consumers of various purchasing types. The empirical studies indicated that there are significant differences in age and education among consumers of various purchasing types, while there is no significant difference in purchasing behaviors. According to the results, MP3 player consumers could be segmented in terms of their involvement. Finally, the marketing implications of involvement theory were discussed and some valuable strategies were suggested for promoting MP3 players.

First, the study analyzed the current shopping website framework, the structure of product exhibition page and the classification of information display and inquire about the users’ viewpoints to the information classification. And then design the experimental web page and test it. The experimental web page design is with the collocation of three kinds of partition ways and two types of index location. Three kinds of partition ways are that one column model, two-column vertical partition model, and two-column horizontal partition model. Two types of index location are that the index is located at the top of the web page and at the bottom of all information. The study measured the time of searching for information, the accurate possibility of search for information, and the frequency of searching for information through the index and through scroll bar, and the preference degree of the web page. The results from the experiment are that it will take the least time on searching for information on web pages of two-column vertical partition model and the index on the top of the web page. In the test of preference degree, subjects like one column model most. The web page of two-column horizontal partition model is at the bottom of all kind of information. The number of times of using index and scroll bar is the most. All experiment combinations don’t affect the accurate rate of searching for information. Therefore, when designing the product exhibition web page of shopping website, not only the information of product displayed should be separated as well as more detail information should be linked but also it will help search for information to set two-column vertical partition frame and guiding index on the product exhibition web page. But the index should be located between the content of web page and browse tools. Key Words：Shopping website, Product exhibition web page, Information classification, Frame, Index.

The diversified, fast, and convenient MP3 players become essential supplies for daily use because of not only the advacement on digital video and audio but also the diversified market demand. Therefore, the greatly profitable opportunities attract enterprises to develop a variety of products to obtain profits in this flourishing market. Because the preferences of consumers are diverse and changeable, the key point to obtain niche is the grip of MP3 player purchasing behavior. Nowadays, there are numerous brands developed in the market, so exploring brand association can understand more about MP3 player purchasing behavior. The conceptual framework of this study the decision process of the EBM model and the brand association is considered to research if different demographic variables have significant differences on the decision process variable, consumption reality variables and brand association. The MP3 players of this thesis exclude CD-based one and only include Flash-based and HDD-based one which are the mainstream. The samples are students who own MP3 players and study in national university in Hsin-Chu City. The Stratified Random sampling survey is from October 2007 to January 2008 in three national universities in Hsin-Chu City. The final result shows that students of different demographic variables in national university in Hsin-Chu City have significant differences on the decision process variable, consumption reality variables and brand association. Besides, the students of different consumption reality have significant differences on the product attribute and brand association.

Garber, Letal. "The Relationships Between Energy Balance, Timing and Quantity of Protein Consumption, and Body Composition in Collegiate Football Players." 2016. http://scholarworks.gsu.edu/nutrition_theses/79.
Full textAbstract:
Background Timing and quantity of protein (PRO) consumption are important considerations for muscle protein synthesis (MPS), fat-free mass (FFM) accretion, and body fat % (BF%) reduction. The effect of PRO ingestion on changes in FFM is mediated by many variables. Past studies have focused on specific composition of carbohydrate (CHO) and PRO consumption (CHO vs. PRO + CHO), and have also investigated PRO intake timing at pre-exercise, post-exercise, or both. Other studies have investigated FFM maintenance and growth with increased PRO consumption during catabolic or anabolic phases of energy balance (EB). These mechanisms have been studied in various populations, including healthy untrained individuals, overweight and obese people, and endurance athletes. However, studies have not explored relationships between the amount and timing of PRO ingested, and the state of EB, as it relates to FFM%. Method/Design A retrospective analysis design was used to assess relationships between PRO ingestion, timing, and EB on FFM in collegiate football players. Subjects were members of an intercollegiate Division 1 football team, had completed a one-day food and activity record, and had body composition assessed as part of a regular team screening procedure. Data acquisition was supervised by a PhD/Registered Dietitian. Food and activity records were analyzed using NutriTiming®, which predicts RMR via the Harris-Benedict equation, uses a MET-based relative intensity activity scale, and accesses the USDA Nutrient Database for Standard Reference, Release 26 to predict hourly EB and PRO consumption. EB was assessed as ±400 kcal EB (EBR), < 0 kcal EB (NEGEB), and > 0 kcal EB (POSEB). Total useable PRO (TUP) was defined as the sum of PRO consumed in units up to 30g max/meal, a value also assessed relative to EB at the time of ingestion. The goal was to assess the amount and timing of PRO intake with EB as these factors relate to FFM. Results Pearson's correlations found that BF% was negatively associated with TUP while in EBR (r=-.253; p=0.049), and FFM% was positively associated TUP in EBR (r=0.279; p=0.030) and in POSEB (r=0.282; p=0.028). NEGEB was positively associated with BF% (r=0.325; p=0.011), and negatively associated with FFM% (r=-0.322; p=0.011). Conclusions Results elucidate that players who ingest PRO in a relatively good energy-balanced state had higher FFM% and a lower BF%. Further, those players consuming TUP while in POSEB had an even stronger positive association with FFM% and a stronger inverse association with BF%. These data reject the null hypothesis that football players who consume PRO in POSEB have less FFM% than those who consume PRO in NEGEB.
