A Comparative Analysis of Power Consumption While Using Open-Source and Proprietary Media Players

This study investigates the power consumption of various media player software applications, comparing open-source and proprietary options. The experiment measured the average power consumption of CPU, GPU, and memory usage of media players such as Kodi, MPC, MPV, SMP, VLC, Windows Media Player, ACG, ALLPlayer, GOM, KMPlayer, LAPlayer, POTPlayer, and RealPlayer while playing 4K video. The results revealed that proprietary media players generally consume less power compared to their open-source counterparts. Statistical analysis, including descriptive statistics and independent samples t-tests, confirmed these findings. Long-term power consumption projections indicated substantial energy savings with more efficient media players. These findings underscore the importance of considering energy efficiency in software selection for sustainable computing.

Media-Player Controlling by Hand Gestures

In this Project we try to control our media player using hand gestures with the help of OpenCV and Python. Computer applications require interaction between human and computer. This interaction needs to be unrestricted and it has made it challenging to traditional input devices such as keyboard, mouse, pen etc. Hand gesture is an important component of body languages in linguistics. Human computer interaction becomes easy with the use of the hand as a device. Use of hand gestures to operate machines would make interaction interesting. Gesture recognition has gained a lot of importance. Hand gestures are used to control various applications like windows media player, robot control, gaming etc. Use of gesture makes interaction easy, convenient and does not require any extra device. Vision and audio recognition can be used together. But audio commands may not work in noisy environments.

Gesture Controlled Music Player

A music player is a computer program for playing audio files or songs encoded in MP3 format. This application will reside in the user's computer, such as iTunes, Windows Media Player and RealPlayer that are used to organize a music collection and play audio files. Our player provides an easy-to-use graphical user interface with symbols provided on the buttons to enable varied types of users to use the player efficiently. Along with the basic functionalities of a music player like playing, pausing, stopping and playing next or previous song, we have provided some interesting features which make our player intelligent. Hence, we have rightly named it ‘Brain Waves Music Player’. It has the ability to judge our sentiments and play the suitable songs accordingly. Also, the player can be controlled using gestures.

Pelatihan Pengembangan Materi Ajar dalam Bentuk Media Power Point pada Materi Struktur Luar Tumbuhan

The challenge of the 21st century is how teachers as much as possible integrate learning with information technology. Lecturers often find <em>slide</em>s prepared by students when the presentation is not good, for example: full text and not contrast. The purpose of this study is to explain how the implementation, response, constraints, and difficulties during the development of materials in the form of a powerpoint <em>slide</em> on the material outside the plant structure. The research approach is based on qualitative research. Data obtained from questionnaires, interviews, and observations on PGMI students Semester 4 academic year 2017/2018. Data analysis using Miles and Haberman version. The results showed that the implementation of the training through three stages of pre-training, training and evaluation. Training includes 10 menus, namely: making titles, core competencies, basic competencies, indicators, concept maps, aperception, sub material outside structure in plants, insert windows media player, practice questions, and compile learning resources. All the trainees were pleased with the material development training through the presentation <em>slide</em>s, 75% said they were useful, and 87.25% said Powerpoint training was something new. The material difficulties faced by students are 50% in the form of structure and content, 25% are Powerpoint templates, 12.5% difficulties create hyperlinks and insert windows video player. Technical obstacles faced in general are 62.5% in the form of time settings, 25% HR, and 12,% laptop supplies are limited.

Investigating the Typical Affective Meanings Influencing Interactivity of Interactive Products for Chinese-Speaking Users

The purpose of this paper was to find out the typical affective meanings for interactive products for Chinese-speaking users. The affective meanings are affective adjectives evoked from interactive products. They are used to investigate the structure of emotional responses to objects, or applied to Kansei engineering to establish the connection between physical property spaces and semantic spaces. However, the affective meanings used in previous studies including the structure of emotional responses and Kansei Engineering were varied both in number and adjectives they used. Over 628 adjectives collected from studies related to emotional responses and Kansei Engineering, and websites were condensed into 298 adjective pairs by five Chinese teachers teaching at Junior high schools in Taiwan. Semantic differential approaches were used to rate 16 windows media player skins with these adjective pairs. Furthermore, Item analysis was used to remove the affective meanings with low discrimination. Factor analysis was performed to reduce the number of affective meanings by discovering the words with similar response patterns. The outcomes showed forty-two typical affective meanings which represented the main factors after Factor analysis. These typical affective meanings were suggested as the affective meanings to describe interactive products.

A Critical Appraisal of Remedies in the EU Microsoft Cases

We discuss and compare the remedies in the two cases antitrust cases of the European Union (EU) against Microsoft. The first EU case alleged (i) that Microsoft illegally bundled the Windows Media Player (WMP) with Windows; and (ii) that Microsoft did not provide adequate documentation that would allow full interoperability between Windows servers and non-Microsoft servers as well as between Windows clients and non-Microsoft servers. After finding Microsoft liable and imposing a large fine, the EU imposed as remedies the requirements on Microsoft (i) to sell a version of Windows without WMP (Windows-N); and (ii) to publish and license interoperability information. Windows-N was a commercial failure, and there has been only limited cross-platform server entry. In its second investigation of Microsoft, the EU alleged illegal tying of Internet Explorer (IE) with Windows. The EU settled with Microsoft with Microsoft undertaking the obligation to ask (through compulsory Windows updates) consumers whose computers have Internet Explorer pre-installed to choose a browser from a menu of competing browsers. Thus, the EU imposed quite different remedies in the two cases: an unbundling remedy for the WMP but a close to a must-carry requirement for IE. We analyze and compare the different approaches.

The European Union, the United States, and Microsoft: A Comparative Review of Antitrust Doctrine

When a seller bundles together two products that have previously been sold separately, the arrangement is sometimes referred to as a tie. If the two products are bound together physically, it is often referred to as a technological tie. In the 1970s, IBM physically integrated so-called peripheral products, such as disk drives and printers which previously had been sold separately, into its central processing units. This integration was then attacked (largely unsuccessfully) by independent manufacturers of peripheral equipment as unlawful tying and as monopolization through tying. More recently, Microsoft has incorporated products, such as browsers and media players, into its operating system, behavior that again amounts to technological tying. It has also improved its server software by heightening the degree to which servers employing that software can interact. By raising the level of interaction among servers equipped with its software, Microsoft has so integrated work group servers as to enable groups of small servers to approach the capacities of mainframe computers. The European competition-law authorities see both matters as problematic. The integration of the media player has been condemned as tying; and the heightened server interaction has been faulted for failing to provide the interoperability that rival server software requires in order to participate on an equal footing with Microsoft server software in Windows work groups. Microsoft’s integration (at least in the view of the European antitrust authorities) also raises issues of essential facilities, and of the role of antitrust in achieving interoperability. Integration of these sorts - e.g., the hardware integrations of IBM and the software integrations of Microsoft - raise antitrust issues, as the extensive litigation in the United States and Europe over Microsoft’s behavior has revealed. We have now reached a moment in time in which both the American and European laws are sufficiently developed to warrant reflection and comparison. That is the task approached in this article. Part I, below, examines the European approach, exemplified in the decisions of the European Commission and the Court of First Instance about the interoperability of Microsoft’s server software. That part also examines the integration of the Windows Media Player into the Windows operating system. Part II reviews the U.S. decisions dealing with Microsoft’s integration of its Internet Explorer browser into its operating system. Since most readers will be familiar with the U.S. litigation at least in its main routlines, that review can be brief. Part III contains an initial comparison of the U.S. and European approaches to product integration. The conclusion in Part IV identifies the major differences and the doctrinal bases on which they rest.

Microsoft Might Under Microscope: Alternative Approaches to Antimonopoly Regulation

In the increasingly flattening world described by Thomas Friedman, transnational corporations are commanding greater influence and control over the world’s resources. These transnational corporations account for approximately one third of the world’s output and seventy percent of world trade. The profit motive, combined with regulatory differences across countries, provides strategic incentives for transnational corporations to bypass restrictive regulations by placing their headquarters and business units in countries with relatively liberal laws. Thus, there is a growing need for regulation that spans national borders mirroring the markets it aims to regulate. In spite of the work that has been done to address problems created by transnational corporations, no magic solution has been found. For example, the United Nations Commission on Transnational Corporations was established in 1974 with a mandate to develop a code of conduct for transnational corporations. Work on the proposed code began in 1975 and a comprehensive draft was completed by 1990, but that draft has never been adopted. Similarly, the World Trade Organization (WTO) has been unable to reach a consensus regarding trade and competition policy. In an effort to illustrate substantive differences between international antitrust regimes and to illuminate the need for a transnational solution, this paper will present and analyze five antimonopoly suits brought in four different countries against the world's largest software company: Microsoft. The two United States (US) cases resulted in consent decrees requiring Microsoft to end its anticompetitive contractual practices and to hide its Internet browser. The European Union (EU) case resulted in Microsoft having to remove its media player from the Windows operating system (OS), disclose interoperability information, and pay a 613 million dollar fine. In Japan, the Japan Fair Trade Commission (JFTC) ordered Microsoft to terminate all non-assertion of patents provisions (NAP) in its license agreements. More recently, Korea ordered Microsoft to unbundle Windows Media Service from Windows Server OS, offer two versions of Windows PC OS: one without Windows Media Player and Windows Messenger and the other with user access to competitors’ products. These divergent results can be explained by the application of broadly similar antitrust laws applied differently by each country’s regime. For example, the European Commission’s ruling reveals a more aggressive approach to Microsoft's antitrust violations than does the United States’ decision. Korea’s ruling has been characterized as even more aggressive than the Commission’s. Although antitrust laws involve many aspects of competition policy including merger review, cartel enforcement, antimonopoly regulation, etc., the scope of the analysis in this paper is limited to Microsoft’s anticompetitive license agreements and anticompetitive tying practices. Thus, this article will examine the antitrust litigation Microsoft has faced in the US and Japan relating to its anticompetitive license agreements as well as the antitrust litigation in the US, E.U., and Korea regarding its anticompetitive tying practices to illustrate alternative antitrust regime responses to a perceived monopoly threat within the context of different regulatory environments. Analyzing these five antimonopoly suits against Microsoft allows meaningful comparison across countries within the limited scope of one company’s challenged anticompetitive business practices. Accordingly, the cases involving Microsoft’s anticompetitive contract provisions are discussed in Section II and the cases challenging Microsoft’s anticompetitive tying practices are discussed in Section III below. Section IV examines procedural and substantive differences across countries. Finally, alternative regime proposals are presented in Section V.

Meet the Archos 605

FRANKLY, I have felt guilty over the past several years for not discussing personal media players like iPods and for not covering more WiFi topics in this column. Maybe it is as the ancients thought, bad ether. Or maybe it is my love for things like high-definition video, five-channel surround sound, and fast and capable computers. But all that is about to change, as I am finally making the move to WiFi, personal media players, and take-it-anywhere technology. It pains me because until very recently, I have been more than happy with the technology I already have. It is the Archos 605 WiFi personal media player that lured me out of my wired comfort zone. I have ranted and raved about technology in the past, but the Archos 605 makes me stretch to find enough superlatives--and expletives--to describe it. I first learned about the 605 while reading an editor's review by Donald Bell on CNET (dated 8/30/07). While I consult CNET reviews often, the opinions that follow are mine and not quite the same as those of Mr. Bell. The Archos 605 is 4.75 inches wide, 3.25 inches tall, and slightly over half an inch thick. Most of the front is taken up by a gorgeous 4.25-inch (diagonally) TFT (thin film transistor) LCD (liquid crystal display) screen with 800 x 480 pixels. This screen, by itself, sets the Archos apart from nearly every other similar device, including the iPod. Two other features put the Archos in a category by itself: a 30-GB hard drive and built-in WiFi for wireless networking. The 605 is available with as little as 4 GB and as much as 160 GB of memory, but I suspect the 30-GB model will be the most popular, and it is the one I recommend. Another feature I like is the small speaker on the front that lets you listen to music without using those annoying ear buds. Together, these and similar features drove me to the store. The screen of the 605 is a multi-touch screen that turns into a qwerty keyboard when you need it. A multi-touch screen allows you to scroll up and down or side to side with a finger or a stylus--two of the latter are provided. There are also six buttons on the right side of the device that are needed from time to time, but you can generally use the touch screen. As soon as I got home with the 605, I turned it on and checked to see if there was any wireless coverage in my neighborhood, but there was none. I guess the local Starbucks is just too far away. Oh well, I think my son has a spare wireless station that I can use with my Mac mini and DSL line to create my very own WiFi network. I plan on setting up my home wireless network soon, but I want to make it as secure as possible, which might take a little study. Expect more on this topic in a future column. If you don't have a WiFi network, you can simply connect the 605 directly to a computer. The 605 comes with a special cable that connects it to the USB 2 port on a computer. You must have a USB 2 port, since this is how you charge the 605's batteries, and a USB 1 port does not have adequate power. Once connected to a computer, the 605 shows up on the Mac desktop or in My Computer on a PC. There are two ways to configure this connection: one makes the 605 appear as an external device; the other makes the 605 act as a Windows Media Player. The first connection method is the one I use, since it allows me to simply drag files to the 605 hard drive. The first order of business for me was downloading some music files from eMusic.com--an Archos partner. I like eMusic for three main reasons. First, the music, which costs 99 cents a song, is not copy protected, so you own it. That means you can transfer it from computer to computer and make as many CDs as you like. Second, I like eMusic because it features a wide selection of old folk, pop, rock, and country music that is nearly impossible to find elsewhere. For example, it was easy to find nearly a dozen versions of Donovan's Catch the Wind and a copy of Lonely Surfer by the Ventures. …

Medical Physics Letters and Multimedia Files

Recently, the editorial board of Medical Physics approved a new feature of the journal entitled Medical Physics Letters. This new feature permits rapid publication of short articles of overriding importance to research or clinical practice in medical physics. Preliminary studies that are scientifically sound and that yield important results are good candidates for Medical Physics Letters. A Letter is a succinct research paper; it is not a letter to the editor, which in Medical Physics is termed Correspondence. Medical Physics Letters should not exceed three (3) journal pages, and must be written clearly and in good English. They are reviewed in a few days with a recommendation of (1) Accept as is; (2) Accept with minor revisions; or (3) Reject. Only one revision is permitted for Letters that are accepted with minor revisions. Medical Physics Letters are archived and citable. Publication of a Medical Physics Letter does not preclude publication of a research article on the topic at a later time. The journal's editorial board believes that many medical physicists are engaged in research that could yield Medical Physics Letters. These physicists are encouraged to submit Medical Physics Letters as a way to gain early recognition of the significance of their research. A few potential authors of Medical Physics papers have expressed interest in submitting multimedia files as part of their manuscripts. These authors believe that the files are essential to the presentation and understanding of the science in the manuscripts. Multimedia files can accompany a manuscript submitted to Medical Physics, and will be examined as part of the review process for the manuscript. Multimedia files that can be submitted with a manuscript include QuickTime Non-Streaming, MPEG, or DV files. If the manuscript is published, the files will be archived with the manuscript in their original format. However, the archiving process places certain limitations on the types of files that can be submitted, as explained below. Digital video files can be submitted with Medical Physics articles and will be reviewed along with the articles. Acceptable file formats include QuickTime Non-Streaming (.qt or .mov), MPEG (.mpg), and DV (.dv). The preferred formats are .mov and .mpeg. Video files should be named [filename.xxx]. When saving a video file, authors should use the “Save As…” option and select .qt, .mov, .mpg, or .dv as the file type. If a digital video file is submitted, a representative “still” image from the file should be selected as a placeholder for the video file in PDFs and print. The extracted image should have reasonable clarity of fine lines and details. Acceptable file formats for still images are PS (.ps), EPS (.eps), and TIFF (.tif). Still images should be named [filename.xxx]. Supplemental video files can be submitted as AVI files, but these cannot be archived with an article since the compression algorithms used to create AVI files are proprietary and do not meet the archival policies and procedures of the American Institute of Physics (the publisher of Medical Physics). AVI files can be retained on-line for an indefinite period. Audio files may also be submitted to Medical Physics, and will be reviewed along with the article that they accompany. Acceptable file formats are PCM (.pcm), WAV (.wav), AIFF (.aif), and MP3 (.mp3) at 128 Kbs or greater. Audio files should be named [filename.xxx]. The acceptable file formats described above are playable with standard media players such as QuickTime and Windows Media Player. A media player should be used to check file properties and image/sound quality prior to submission. For video submissions, fonts, lines, and image details should be of sufficient size and weight to be visible when played at half size. File size should be limited to make download times reasonable since streaming formats are not acceptable at this time. A recommended size is 3–5 Mb for each multimedia file. Authors should use an acceptable compression codecs (compression-decompression algorithm) to reduce file sizes. Animation must be formatted into a standard video file. The nature of the media content, such as video or audio. The media file type, such as QuickTime, DV, MPEG, WAV, etc. The duration of the media object playing time (seconds) for video and audio. For video, the size of the video image (height width in pixels). The name and version of the software used to create the media object, such as ADOBE PREMIERE ELEMENTS v. 2.0.

Interoperability and Foreclosure in the European Microsoft Case

Introduction The cases in the US and Europe against Microsoft have been perhaps the most high-profile antitrust cases in the last twenty years. In the various Microsoft cases, antitrust authorities in the US and Europe took on what was at some points the most valuable company in the world and its CEO Bill Gates, the world's richest man. After five years of investigation, on 24 March 2004, the European Commission held Microsoft guilty of an abuse of a dominant position under Article 82 and imposed the largest fine ever for such an antitrust violation in Europe – €497 million. The Commission also demanded major forward-looking behavioural remedies including compulsory licensing of intellectual property and forced unbundling. This degree of behavioural intervention is highly unusual and led to continued conflict about the implementation of the remedies. The Decision found that Microsoft had abused its dominant position in the PC operating system market in two ways: ‘deliberately restricting interoperability between Windows PCs and non-Microsoft workgroup servers, and by tying its Windows Media Player (WMP), a product where it faced competition, with its ubiquitous Windows operating system.' As remedies for these violations the European Commission ordered Microsoft: ‘within 120 days, to disclose complete and accurate interface documentation which would allow non-Microsoft workgroup servers to achieve full interoperability with Windows PCs and servers’; ‘within 90 days, to offer to PC manufacturers a version of its Windows client PC operating system without Windows Media Player’. The case is fascinating as it touches on one of the key issues concerning the conduct of modern competition policy': how should we think about the role of antitrust in high-tech industries dominated by rapid innovation?

The Book Report, Version 2.0: Podcasting on Young Adult Novels

O ver the past five years, the Web has undergone subtle but important shifts in structure and function. Taken as a whole, these changes mark the emergence of a new Web, generally called Web 2.0 by its proponents. Unlike the early Web, in which expert users, called Webmasters, developed sites with unchanging content, Web 2.0 is characterized by frequently updated sites, publicly constructed and shared information, and easy-to-use online applications, most of them free. If the early Web gave us the online Encyclopedia Britannica, Web 2.0's most heralded achievement is Wikipedia, a user-created encyclopedia that anyone can edit. In other words, as Time magazine proclaimed, Web 2.0 is all about you-the Web user (Grossman 41). New Web 2.0 applications-blogs, wikis, social networking sites, and more-offer educators exciting ways to publish student work to the Web. Of these, the podcast is particularly useful for reinforcing the goals and practices of literature instruction. Simply defined, a podcast is audio delivered over the Web in serialized episodes. You might think of a podcast as a blog in audio form: Like the blogger, the podcaster publishes content to the Web on a regular basis, only the content is recorded rather than written. Listening to a podcast requires media software such as iTunes, Windows Media Player, or an RSS aggregator such as Google Reader. Once installed, this podcatching software finds, downloads, and plays podcasts. Podcasts may be transferred to a personal MP3 player for portable listening, but this hardware is not necessary. In fact, the idea that podcasting requires an iPod is a persistent misconception, perhaps because pod is associated with the iPod, the ubiquitous MP3 player with the trademark white earbuds and snazzy television spots. I recommend thinking of pod as an acronym for personal on-demand, a good description of the highly individualized and instantly available content that podcasts offer. As with blogs, podcasts can take a variety of forms and can cover an enormous range of subjects. Many mainstream media outlets now offer complete or supplemental programming via podcast: National Public Radio, for example, now podcasts its award-winning This I Believe essay series; the New York Times offers, among others, a podcast that summarizes the major headlines of the day. Some p dcasts provide alternative takes on the mainstream media. The Alive in Baghdad podcast, for instance, is produced by a team of Iraqi and American journalists and aims to counter the sound-bite riven news by recording the real stories of Iraqis living through the war. But podcasting goes well beyond mainstream topics: special-interest groups use podcasts to advocate their causes, and individuals publish podcasts on pet topics. The podcasts archived at iTunes alone seem to cover nearly every subject imaginable, from Harry Potter (MuggleCast) to hairstyles (Secrets of Style with Kim Foley) to hairballs (Purina Animal Advice Podcast Series). And iTunes is only one of hundreds of podcast directories. Other popular sites include Podcast

Programming fundamentals and innovation taught through windows media player skin creation

Windows Media Player user interface "skin" creation has proven an extremely effective method to reinforce practical object oriented programming techniques. Skin creation motivated non-engineers, women and even high school students to learn XML, and Jscript scripting language. Non-computer science students were especially excited when their custom media player user interface operated as intended. Many students demonstrated their skin to potential employers as evidence of their creativity and programming prowess.This paper discusses how skin programming is related to the object oriented paradigm and may be used as an exemplary collegiate interdisciplinary design project. Examples illustrate how skin creation can emphasize design principles, fundamental programming concepts, and group software development. Software innovation is advanced via novel windows media player skins incorporating recently released features to provide an enhanced user interface for a target domain.

Ms and the eu: naming a non-starter

the eu recently forced microsoft to issue a second version of its windows xp operating system without a built-in windows media player, ruling that, by bundling its own media player, microsoft was effectively blocking competition from rivals (particularly real player and quicktime). microsoft's monopolistic approach in this case also landed it a fine of €497.2 million ($665m). the wrangling lasted well over a year, during which time windows xp with bundled media player had been sold so widely in europe as to partly invalidate the eu's attempts at stopping the us company monopolising and controlling the market. ‘the second version of windows will reflect what consumers want, and not what microsoft imposes on them,’ was the triumphant but belated comment of mario monti, the former eu commissioner in charge of competition.

Microsoft v. EC: In the European Courts

On 22 December 2004, the President of the Court of First Instance (CFI) unequivocally rejected Microsoft's application to suspend the Commission's Decision in Case COMP/37.792, Microsoft of 24 March 2004 (the Decision) until the CFI rules on Microsoft's application to annul the Decision. The Decision found that Microsoft had abused its dominant position by refusing to supply critical interoperability information to competitors (the interoperability case) and by unlawfully tying the sale of its Windows Media Player ( WMP ) with its dominant Windows client PC operating system (Windows) (the tying case). The Commission imposed record fines of EUR 497.2 million and required Microsoft to disclose certain interoperability information to competitors to enable them to produce work group server operating systems that interoperate fully with Windows, and to offer a version of Windows without WMP pre-installed. Although the President was careful not to prejudge the outcome of Microsoft's pending annulment proceedings, he did nonetheless identify a number of questions that he considered would require close examination in these proceedings. These questions may be of more interest now that the President will be a member of the 13-strong panel of judges that will hear the annulment proceedings. This article considers the President's order (the Order) and some of its implications. Section I summarises the main aspects of the Order focusing on the President's reasons for rejecting Microsoft's case for suspension. Section II discusses the issues that the President considered would warrant careful assessment in the annulment proceedings. We also consider summarily the impact of the Order on the ongoing remedies discussions between the Commission and Microsoft. Section III offers a brief conclusion.

Performance Test of Web Based 3D Medical Image System using Image Streaming Technique

OBJECTIVE: It is still the important subject that 3D visualizing of medical images to help patient diagnose. There were many challenges for fast 3D visualization but it has some limitations that volume rendering without high price's hardware and software. Some techniques through the web were suggested to construct high quality's 3D visualization even though it was an only poor personal computer. This technique could share the volume rendering board and diagnose 3D images together. However there are some problems to construct web based 3D visualization. These are network delay, optimized visualization and security etc. The purpose of this paper was to visualize and control the 3D medical image having a high quality on the web. METHODS: To construct this system, we used mainly three tools which were VolumePro1000 board, WMV9(Windows Media Video 9 Codec) and socket functions based on TCP(Transmission Control Protocol). VolumePro1000 board could calculate quickly heavy matrixes of 3D images using phong's shading and shear-warp factorization. WMV9 was able to compress efficiently live images and to apply image streaming technique. Socket functions based on TCP transmitted messages to control the 3D images. RESULTS: We developed 3D visualization system and evaluated about image qualities and transmission conditions of different compression rates on unfixed network condition. CONCLUSION: It was big advantages that WMV9 encoder could decode automatically in many platforms(desk top, PDA, notebook, cellular phone, etc) without installing specific decoding programs if they only have Windows Media player. We expect 3D visualization system to be utilized various biomedical fields such as IIGS(Interactive Image Guided Surgery), CAD(Computer Aided Diagnosis) and Tele-medicine technologies.

Real-Time Planning for Multiple Autonomous Vehicles in Dynamic Uncertain Environments

In a highly dynamic environment, an adaptive real-time mission planner is essential for controlling a team of autonomous vehicles to execute a set of tasks. An optimal plan computed prior to the operation will no longer be optimal when the vehicles execute the plan. This dissertation presents a framework and algorithms for solving real-time task and path planning problems by combining Evolutionary Computation (EC) based techniques with a Market-based planning architecture. The planning system takes advantage of the flexibility of EC-based techniques and the distributed structure of Market-based planning. This property allows the vehicles to evolve their task plans and routes in response to the changing environment in real time, and under varying computational time windows.* *This dissertation is a compound document (contains both a paper copy and a CD as part of the dissertation). The CD requires the following system requirements: Windows MediaPlayer or RealPlayer.

Tele-diagnostic and Therapeutic Guidance in Urology

To design a Web-based network for diagnostic and therapeutic guidance in urology. We designed an architectural model of a low-cost multimedia Web platform that runs on a collection of distributed collaborative network nodes to provide a set of urologist-oriented Web-enabled services. Any node of the platform was able to share patient-oriented data via automated processes with appropriate authorization, confidentiality, and high-security protocols. The urologist can show the details of the records of patients and additionally enrich the world experience with his or her own cases. Video clips maintained locally at the nodes will be accessible by clinicians in a trouble-free way with MS Windows Media player and a relatively small amount of source code. The primary advantage of this architectural model is that it provides Web-enabled integrated urologic services while using a distributed storage scheme for urological video files (AVI format) and a global repository of laboratory results using Extensible Markup Language (XML) and Data Grid technologies. In addition, this model provides decision-support services (knowledge from a global database and predefined procedures). The architecture model is based entirely on HTTP, XML, GRID-like environment and DotNet technologies. Finally, the platform provides extensibility and scalability targeted to large-scale Web-enabled global urologic databases.
