Abstract: The size, complexity and performances of modern wireless communication circuits are getting more and more challenging whereas marketing time and cost must be reduced as much as possible. In order to fill the current lack in CAD tools, this work is dedicated to the mixed simulation of complete communication systems driven by digital and digitally modulated RF signals. This paper describes a methodology for top-down design, modeling, and simulation of complete RF system using hardware description language VHDL-AMS (Very high speed integrated circuit Hardware Description Langage – Analog Mixed Signal). As application, we consider a complex M-QAM system (transmitter, channel, and receiver) and we show some details of

The study aimed to assess the accuracy and reproducibility of occlusal caries depth measurements obtained from different imaging modalities. The study comprised 21 human mandibular molar teeth with occlusal caries. Teeth were imaged using film, CCD, two different cone-beam computerized tomography (CBCT) units and a microcomputer tomography (micro-CT). Thereafter, each tooth was serially sectioned, and the section with the deepest carious lesion was scanned using a high-resolution scanner. Each image set was separately viewed by three oral radiologists. Images were viewed randomly, and each set was viewed twice. Lesion depth was measured on film images using a digital caliper, on CCD and CBCT images using built-in measurement tools, on micro-CT images using the Mimics software program, and on histological images using AxioVision Rel. 4.7. Intra- and inter-rater reliabilities were assessed according to the Bland/Altman method by calculating Intraclass Correlation Coefficients (ICCs). Mean/median values obtained with intraoral systems were lower than those obtained with 3-D and histological images for all observers and both readings. Intra-observer ICC values for all observers were highest for histology and micro-CT. In addition, intra-observer ICC values were higher for histology and CBCT than for histology and intra-oral methods. Inter-observer ICC values for first and second readings were high for all observers. No differences in repeatability were found between Accuitomo and Iluma CBCT images or between intra-oral film and CCD images. Micro-CT was found to be the best imaging method for the ex vivo measurement of occlusal caries depth. In addition, both CBCT units performed similarly and better than intra-oral modalities.

This paper considers the role that representational methodologies play in the dialogue between archaeological material data and narrative creation. It does this specifically in relation to the production and consumption of knowledge at the site of Petsofa, a two-period highland site overlooking the Palaikastro bay in East Crete. A new paradigm, known as ArcSeer (www.arcseer.com), is presented as an alternative approach to the traditional methods of recording, reading and representing the archaeological record. ArcSeer's approach exploits exciting advances made within the technological spheres of web application development, distributed database design and 3D visualisation. This paper will argue that the manner in which the Petsofa site data has been represented to date has significantly influenced its reading by its audience. ArcSeer is particularly interested in accommodating the multiple interpretations that fuel and derive from these representations. If we accept the basic premise that representation cannot be considered a neutral act, then a greater reflexive awareness of this fact must be accommodated by the representational devices that the discipline employs. The ArcSeer project is one such experiment along this road of enquiry.

Digital forms of sound manipulation are eroding traditional methods of sound development and transmission, causing a disjuncture in the ontology1 of music. Sound, the ambient phenomenon, is becoming disrupted and decentred by the struggles between long established controls, beliefs and desires as well as controls from within technologized contexts. I posit that music technologies are reshaping concepts of time and space, and digital mastery now appears to be the valued musical knowledge. It is necessary to consider a new paradigm for what it means to be musical-in-the-world. Virilio suggests that, rather than being democratic, technology “has hijacked democracy in a mediatized, claustrophobic world” (2005, 339), contributing to a posthuman condition through the destruction of embodied experience.

Online media consumption in India has increased post cuts in the Data rates; and it will continue to increase with the availability of cheap data. Printed newspapers have sustained their growth in this digital age, but will they continue to sustain themselves in the coming years when everything is available on the internet? While there is an increase in the sales of printed newspapers in India, there is a noticeable decline in the distribution and consumption of printed newspapers in the USA. We have surveyed different sectors of society to obtain information on people’s reading habits and patterns, which will gauge whether physical newspaper distribution will follow the same pattern in India as in the USA. Our study shows that a large number of youth want access to information that is summarized and easily available; they have also shown interest in revisiting old articles and information which is available in online archives.

Leif Kramp untersucht erstmals umfassend die Gedächtnisrelevanz des Massenmediums Fernsehen sowie den archivischen und musealen Umgang mit der Fernsehgeschichte. Anknüpfend an die interdisziplinären Zweige der Gedächtnisforschung analysiert der erste Band die Bedeutung des Fernsehens seit Beginn des regelmäßigen Programmbetriebs in Deutschland und Nordamerika unter gedächtnistheoretischer Perspektive. Damit legt dieser Band den Grund für eine differenzierte Bewertung des Fernsehens als Medium des Erinnerns und Vergessens. Auf Basis einer breiten empirischen Erhebung bei zahlreichen Institutionen in Deutschland, Kanada und den USA befasst sich der zweite Band mit dem Status Quo und den Perspektiven der Verwaltung und Nutzung von Überlieferungen aus der Fernsehgeschichte. Kramp analysiert die maßgeblichen Problemstellungen, mit denen sich Museen und Archive konfrontiert sehen: von Fragen der Auswahl, Bewahrung und Zugänglichkeit von Fernsehüberlieferungen bis hin zu ihrer Präsentation und dem Medienwandel, und diskutiert Strategien für die Arbeit von Fernsehmuseen im digitalen Medienzeitalter.

The last decade witnessed a growing interest in research on content-based image retrieval (CBIR) and related areas. Several systems for managing and retrieving images have been proposed, each one tailored to a specific application. Functionalities commonly available in CBIR systems include: storage and management of complex data, development of feature extractors to support similarity queries, development of index structures to speed up image retrieval, and design and implementation of an intuitive graphical user interface tailored to each application. To facilitate the development of new CBIR systems, we propose an image-handling extension to the relational database management system (RDBMS) PostgreSQL. This extension, called PostgreSQL-IE, is independent of the application and provides the advantage of being open source and portable. The proposed system extends the functionalities of the structured query language SQL with new functions that are able to create new feature extraction procedures, new feature vectors as combinations of previously defined features, and new access methods, as well as to compose similarity queries. PostgreSQL-IE makes available a new image data type, which permits the association of various images with a given unique image attribute. This resource makes it possible to combine visual features of different images in the same feature vector. To validate the concepts and resources available in the proposed extended RDBMS, we propose a CBIR system applied to the analysis of mammograms using PostgreSQL-IE.

This article reviews research into why people watch television. Christensen (2003) proposes businesses are best understood by looking at the way they help people address their jobs-to-be-done. If new forms of television are more likely to succeed to the extent that they do the jobs now done by traditional television; then to understand how people will use future forms of TV, we must understand how viewers use traditional TV.

Al-Quran is the great revelation promised by Allah SWT of its protection encompassing the aspect of recitation and writing. The revolving time has witnessed various innovations featured by Islamic scholars to ensure that Al-Quran is preserved. Beginning with mushaf which was transferred from bone, stone, palm branch or animal skin into sheets of paper until the latest form which is digital, scholars have never missed out from paying attention to its protection from all aspects. Besides that, concern of the community also has played its role in increasing the sensitivity of Muslim people to any form of mistake that happens in the publication of Al-Quran mushaf and at the same time the perfectness of Al-Quran can be preserved well and carefully. Concern by the Malaysia government through development of this Smart Quran application indirectly is capable of controlling the usage of various al-Quran mushaf application nowadays. Hopefully, this effort can be continued for the sake of goodness for the global community.

Radiologic Education has substantially changed throughout the years and has certain advancements that have left the country catching on. It has transitioned from analog to digital imaging, which considerably left developing countries behind. Consequently, general radiography practices are assumed to differ from the previous years. Employing a sequential explanatory research design, the study looked into the radiologic interns' competencies in specific parameters such as preparation, patient care and management; positioning; and image acquisition and processing. Using a researcher-made questionnaire, 50 radiologic interns from four academic year batches were invited to participate in the study. Interpreted responses are cross-referenced through the interview data that were gathered from 12 participants, equally representing each batch. The study also probed the interns' general learning preference using the VARK questionnaire. Both of the questionnaires underwent Cronbach Alpha Test of Reliability. The data was probed and analyzed using Regression Analysis; to which the research findings gave an inference that the learning preferences positively affect the clinical competencies of the radiologic interns, providing the institution a broader perspective on improving the interns' educative capacity. It also strengthens the Radiologic Technology program, giving importance to the three generated themes: Rehearsals of procedures, Application more than Theories, and Demonstration of Skills.

Arts and Technology has been involved in an interaction with each other since the existence of Human being. Technological innovations have not only included the society but also the art. ’The New Media’concept which has been the focus of this issue has also affected the visual communication design.The visual communication design has acreative process in which the technology and design are combined and communication is established. Additionally, the decrease in the interest in desktop publishing has led to the development of the concept of ‘the new media.’The new media design concept has been an important field especially in the developing countries. Because, in our century where competency almost disclaims right of living to the other, the companies and trademarks are making use of the power of visual communication designin order to bring up their productions one step forward than the others, to boost their pre-occupyingness, and to turn will of purchasing into permanency. In this study, the reasons for the innovation-visual communication design into the digital field, along with the new media concept have been addressed.

Az utóbbi évtizedekben rendkívüli mértékben felgyorsult technológiai fejlődés és az IKT eszközök egyre jelentősebb térhódítása következtében kialakuló információs társadalom számos új kihívást generált tagjai számára. Megváltozott az információhoz jutás módja, sebessége, új kommunikációs formák jöttek létre, átalakultak a munkaerő piac követelményei. Folyamatosan csökken azoknak a szakmáknak az aránya, melyek a digitális írástudás legalább minimális szintje nélkül is betölthetők és a hétköznapi tevékenységeinkhez is egyre nélkülözhetetlenebbé válnak ezek az ismeretek.
A változások természetesen az oktatásira is hatást gyakoroltak, sőt elengedhetetlenül fontossá vált az IKT eszközök alkalmazása, magas szintű integrálása az oktatási folyamatba. Ha ugyanis a XXI. századi tanulókat XX. századi eszközökkel és módszerekkel oktatjuk, akkor a diákok érdeklődése, motiváltsága és ezzel szoros összefüggésben a tanítási folyamat hatékonysága, eredményessége a legtöbb esetben meglehetősen alacsony szintű lesz. Azonban ha használni kezdjük a digitális technológiát, akkor jelentős javulást érhetünk el, de a napjaink igényeinek valóban megfelelő oktatás csak akkor valósulhat meg, ha a módszereken is változtatunk. Ez a könyv ezt a bonyolult, soktényezős, jelenleg is zajló folyamatot vizsgálja.
A kötetben egyrészt a digitális technológia fejlődése, terjedése által generált társadalmi változásokat, az átalakuló tanítási-tanulási környezetet és az ezekből indukálódó elvárásokat tekintjük át, másrészt egy kutatássorozat adatait felhasználva az új kihívások, feltételrendszerek kusza hálójában tevékenykedő pedagógusok attitűdjét, illetve a tanítási folyamat változásának jellemzőit vizsgáljuk meg.

Abstract- This paper presents the design of a Digital Clock that displays 24-hours, minutes and seconds. A time-based oscillator containing a 555 timer Integrated Circuit (IC) in an astable mode with a frequency of 1Hz provides the clock pulses for the seconds display. On each of the Dual Seven-Segment (7-Segment) displays for hours, minutes and seconds, Binary Coded Decimal (BCD) counters converts each clock pulse received into a 4 bit 8421 synchronous logic output. Display decoders/drivers connected to each 7-Segment display decodes the 4-bit 8421 logic and converts it to a 7-Segment display codes. The dual-7-Segment displays of each of the hours, minutes and seconds output the figures 0 to 9 according to the set time. The clock is designed to work with the stabilized 9V DC voltage power supply.

The question of interactivity in technical commu-nication is complex. First, building interactive technical documents means relinquishing some amount of control over authorship, readership, and document presentation, each of which can be frightening for a variety of reasons, not the least of which is the uncertainty involved in this process. Second, interactivity in technical documentation must also compete with interactivity in entertainment, a moving industry target with billions of R&D dollars invested each year.
