Virtex? 2. 5v field programmable gate arrays

All pads are protected against damage from electrostatic discharge (ESD) and from over-voltage transients. Two forms of over-voltage protection are provided, one that permits 5 V compliance, and one that does not. For 5 V compliance, a Zener-like structure connected to ground turns on when the output rises to approximately 6.5 V. When PCI 3.3 V compliance is required, a conventional clamp diode is connected to the output supply voltage, VCCO. Optional pull-up and pull-down resistors and an optional weak-keeper circuit are attached to each pad. Prior to configuration, all pins not involved in configuration are forced into their high-impedance state. The pull-down resistors and the weak-keeper circuits are inactive, but inputs can optionally be pulled up.
Performance of coded slow-frequency-hopped TDMA cellular systems

The outage probability as a function of the number of users/MHz/cell is adopted as the performance measure for evaluating the capacity of a time division multiple access (TDMA) based slow frequency hopped cellular system. A Gilbert-Elliott model to arrive at an estimate of system capacity is used. The Gilbert-Elliott model and expressions for codeword outage probability are derived. Results are provided for mobile to base transmission considering voice activity, power control, antenna selection diversity, and channel coding. The analysis presented is general, but results are restricted to a shortened Reed-Solomon code.
Enhancement of High Data Rates in Wireless Communication Networks Using MIMO-OFDM Technology

: Wireless communication systems require high transmission speed, improvement in spectral efficiency, and increasing speed and robustness. Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital data on multiple carrier frequencies. OFDM has developed into a popular scheme for wideband digital, whether wireless or over copper wires, used in applications such as digital television and audio broadcasting, DSL broad band internet access, wireless networks, and 4G mobile communications By using Multiple input and multiple output (MIMO) i.e. multiple antennas at the transmitter and multiple antennas at the receiver, the spectral efficiency will increase. For broadband communications, OFDM turns a frequency selective channel into a set of parallel flat channels, which significantly reduces the receiver complexity. In this paper, we applied Space-Time Coded Multiple-Input Multiple-Output OFDM (STC MIMO-OFDM) concept for spreading the transmitted symbols. In the proposed systems, a multidimensional diversity, including time, frequency, space and modulation diversities, can be used, resulting in better bit error performance in AWGN channel for with and without padding as well as for with and without convolution coding.
The effects of a media campaign on beliefs and utilization of imaging examinations in Norwegian patients with low back pain

Aims: Several authors have reported an overuse of imaging examinations for unspecific low back pain conditions. In this study, we examined the influence of a media campaign for better understanding and management of back pain in the general population on utilization of imaging examinations. Methods: The media campaign Active Back ran for three years (2002-2005) in two Norwegian counties and the results were compared to the adjacent control county. Numbers of imaging examinations were collected manually from every radiology department in each of the three counties, while belief measures were collected through a telephone survey before, during and after the campaign. Beliefs of the health care providers were collected through questionnaires. Results: We observed a decrease of X-rays by 35% in the intervention counties and by 33% in the control county. The number of CT scans decreased by 51% and 57% respectively. The number of MRI scans increased by 152% in the intervention counties and by 596% in the control. Combining all modalities, the number of imaging examinations increased by 3% in the intervention counties and by 56% in the control county. There was a tendency both in the general public and among the health care providers towards less trust in the usefulness of X-rays in all counties during the study period. The health care providers in the control county seemed to recommend imaging more often than their colleagues in the intervention counties. Conclusion: Despite slightly increased scepticism among the general public and health care providers, we observed an overall increase in utilization of imaging modalities. The dramatically increased utilization in the control group was likely explained by an increased capacity for MRI examinations obtained by the opening of a new radiology clinic, and not as an effect of the media campaign.
Multilevel Based Global Routing Algorithm for Hierarchical FPGA

This paper presents an efficient global routing algorithm for a hierarchical interconnection architecture of FPGA. What is different from the traditional FPGA routing algorithm is that the proposed algorithm takes advantage of the hierarchical structure of this particular FPGA. We use a hierarchical tree as the routing resource representation of the corresponding interconnection architecture. In the routing phase, the global routing problem for each net is represented as a sub-tree determination problem. As soon as the location of each Logic Block is fixed, we can use a tree-growth-like algorithm to determine the sub-tree on the corresponding routing resource tree. The algorithm is very efficient and fast since the sub-tree is determined once we determined the position of each Logic Block. On the other hand, we can use this method to evaluate the routability of the corresponding placement results.
Registered depth and intensity data from an integrated vision sensor

We describe the design and implementation of an integrated imaging sensor to acquire registered depth and intensity data to determine the 3D geometry and the natural reflectance of a scene. Since a linear translation stage is used for object scanning, image sequences of constant motion along the x-axis may also be derived. The complementary information of these sources can resolve the uncertainty and ambiguity in data from a single source or provide multiple processing paths to subsequent image segmentation and understanding.
The relocation of cinema

In October 2011, the British artist Tacita Dean presented her work Film at the Tate Modern in London.2 Dean’s installation is a f ilm short projected in a continuous loop onto a large screen in a dark space furnished with seats for visitors. The written explication at the entrance to the room draws attention to the presence of all these elements: ‘35mm colour and black & white portrait format anamorphic f ilm with hand tinted sequences, mute, continuous loop, 11 minutes. Large front projection; projection booth; free standing screen; loop system; seating. ’ In her article in the Guardian, Charlotte Higgins described Film as ‘pay[ing] homage to a dying medium’. 3 In addition, Film is undoubtedly an act in defense of f ilm stock – that same f ilm stock which Kodak announced (on 22 June 2009) it would cease to manufacture after 74 years of production, due to a steep decline in sales. Beyond the preservation of a medium-support, Film seems to also invoke the preservation of a medium-device: in the Tate we f ind a projector, a reflective screen, a darkroom, a bench on which to sit – all things which are becoming increasingly rare in the age of digital images. In essence, Dean attempts to restore all the essential elements of the cinema, those which characterise its technical foundation. Paradoxically, she sets these elements before us as components of an artistic installation; she gathers and reunites them for the purposes of a work intended for a gallery or museum. It is no accident then that visitors to Turbine Hall do not hold the same expectations or display the same behavior as they would if they found themselves at the British Film Institute Southbank (which is not far from the Tate) to see a EUROPEAN JOURNAL OF MEDIA STUDIES
Eyetracking Web Usability

Eyetracking Web Usability is based on one of the largest studies of eyetracking usability in existence. Best-selling author Jakob Nielsen and coauthor Kara Pernice used rigorous usability methodology and eyetracking technology to analyze 1.5 million instances where users look at Web sites to understand how the human eyes interact with design. Their findings will help designers, software developers, writers, editors, product managers, and advertisers understand what people see or dont see, when they look, and why.With their comprehensive three-year study, the authors confirmed many known Web design conventions and the book provides additional insights on those standards. They also discovered important new user behaviors that are revealed here for the first time. Using compelling eye gaze plots and heat maps, Nielsen and Pernice guide the reader through hundreds of examples of eye movements, demonstrating why some designs work and others dont. They also provide valuable advice for page layout, navigation menus, site elements, image selection, and advertising. This book is essential reading for anyone who is serious about doing business on the Web.
A quantitative model-based expert system for LAN development

A quantitative model-based expert system, or QMB for short, is described. A QMB is a rule-based system coupled to an analytic model. The QMBs provide another level of refinement over rule-based systems by giving quantitative answers to problems. He discusses the difficulties associated with the design of a shell for a QMB and proposes the use of a semishell, which assists the knowledge engineers in writing the logic, uncertainty and inference modules of the QMB expert system program. The design and coding of the modules that deal with the numerical data is left to the knowledge engineer. The operation of a QMB having 43 rules is described. A software architecture is presented that can dynamically change its operation. The purpose of the architecture is to produce an expert system that can think more like human beings. <<ETX>>
Computer support for collaborative learning environments

This paper deals with computer support for collaborative learning environments. Our analysis is based on a moderate constructivist view on learning, which emphasizes the need to support learners instructionally in their collaborative knowledge construction. We will first illustrate the extent to which the computer can provide tools for supporting collaborative knowledge construction. Secondly, we will focus on instruction itself and show the kinds of advanced instructional methods that computer tools may provide for the learners. Furthermore, we will discuss the learners’ prerequisites and how they must be considered when constructing learning environments.
Cross-Media Retrieval Method Based on Space Mapping

This paper puts forward a novel cross-media retrieval approach, which can process multimedia data of different modalities and measure cross-media similarity, such as image-audio similarity. Both image and audio data are selected for experiments and comparisons. Given the same visual and auditory features the new approach outperforms ICA, PCA and PLS methods both in precision and recall performance. Overall cross-media retrieval results between images and audios are very encouraging.
Optimal control and variable structure combination using a permanent-magnet synchronous motor

Optimal control theory is applied to design of the position and speed controllers for an AC servomotor drive using a permanent-magnet synchronous motor. In the proposed scheme, stator currents are controlled by an inner loop based on the principle of predictive control. Performances and robustness of the outer loops are examined and the structure variable is added to it to provide better performance in a wide range. The proposed scheme has been implemented on an experimental 1.5 kW servomotor drive using a floating-point DSP (TMS320C30). Experimental results are presented and discussed. <<ETX>>
Coarse-grained cloud synchronization mechanism design may lead to severe traffic overuse

In recent years, cloud sync(hronization) services such as GoogleDrive and Dropbox have provided Internet users with convenient and reliable data storing/sharing functionality. The cloud synchronization mechanism (in particular, how to deliver the user-side data updates to the cloud) plays a critical role in cloud sync services because it greatly affects the cloud operation cost (in terms of sync traffic) and user experience (in terms of sync delay). By comprehensively measuring tens of popular cloud sync services, we find that their cloud sync mechanisms differ greatly in sync performance and design granularity. Quite surprisingly, some very popular services (like GoogleDrive and 115 SyncDisk) utilize a quite coarse-grained cloud sync mechanism that may lead to severe traffic overuse. For example, updating 1-MB data may sometimes result in 260-MB sync traffic. In this paper, we conduct a comparative study of various cloud sync mechanisms by analyzing their respective pros and cons under different situations, unravel the pathological processes for their traffic overuse problems, and finally provide insights/solutions for better choosing/designing a cloud sync service.
Using stereo camera system to realize realistic video avatar in virtual environment

With the appearance of different kinds of virtual environment systems, the technology of realistic video avatar is becoming a hotspot of research. Our target is to create a realistic video avatar with less hardware investment and limited computation. In this paper, we introduce a method that combines a single stereo camera and 3D head model to engender a realistic video avatar. To engender the video avatar's most important part - the face part - we use the 2D image and depth map, which is generated by the stereo camera. To engender the other parts of the 3D head model, we map the head's texture to the 3D head model.
Design and Simulation of Wilkinson Power Divider for SCX Wideband Applications

This paper reports the design of a power divider for high frequency applications i.e for frequencies greater than 9GHz. The Wilkinson power divider circuit was chosen to be modified to meet the chosen specifications because of its advantages over the power dividers. The circuit design mainly aims for equal power division across the two output ports of the Wilkinson power divider circuit. Power division mainly equal power division is very essential and complex to achieve at higher frequencies. And the design of such a power divider is ideal for use in high frequency applications like radar systems, electronic missiles, optical fiber systems etc. The WPD circuit mainly consists of three microstrip lines connected in such a way that it forms a three port network. Two resistors of equal resistance were placed between the ports-2&3 which ensures equal signal flow in both the directions i.e between port-2 to port-3 and vice-versa. This ensured equal power division among the output ports. All the parameters were measured using the design equations of the microstrip line. The simulation results of the circuit for the above design showed improved isolation losses, S23 of about −12.61 dB and return losses, S11 of −20.72dB at frequency 10GHz. The frequency range of operation obtained from the simulation results was between 3 to 13.8GHZ. Hence the bandwidth(by considering return loss, S11) of the circuit obtained is ∼10GHz which is very appreciable.
An efficient method for computer aided noise analysis of linear amplifier networks

A method for computer aided noise analysis is presented which is based on a description of noise by means of correlation matrices. The method is a two-port analysis and it is, therefore, applicable to circuits which are composed of simple two-ports with known noise performance. The correlation matrix concept holds two main advantages over other methods of noise analysis. Partially correlated noise sources can be treated without any loss of efficiency and information concerning minimum noise figure and noise matching conditions is obtained.

A decision making support system for selecting appropriate online databases

An experimental decision making support system for selecting appropriate online databases is presented. Three levels of metadata and primitive functions for manipulating metadata are proposed to provide basic functions of the decision making system. Primitive functions and metadata extracted from existing databases are classified into three levels from the following viewpoints: (1) degree of precision of decision making for database selection, and (2) property of metadata that gives criteria for selecting appropriate databases. From these viewpoints, the authors present a systematic design methodology for database selection in multidatabase environments. Furthermore, a primitive function set for selecting appropriate databases is exemplified to show the feasibility of the proposed system. <<ETX>>

Assessment of Complex Trauma Exposure, Responses, and Service Needs Among Children and Adolescents in Child Welfare

Exposure to multiple, chronic interpersonal traumas, often referred to as complex trauma exposure, can impact several areas of mental health need and functioning. A comprehensive assessment of needs and strengths is essential to making appropriate service recommendations. This study assessed 4,272 youth within the Illinois child welfare system using the Child and Adolescent Needs and Strengths (CANS). A significant proportion of this sample had multiple/chronic caregiver-related trauma. Children with this complex trauma exposure exhibited more traumatic stress and mental health symptoms, risk behaviors, and day-to-day functioning difficulties, and fewer strengths compared to other children. Implications for these findings are discussed in terms of appropriate treatment/service planning and improved diagnostic classification to better capture the complex trauma needs among youth in child welfare.
Stargrazer One: A New Architecture for Distributed Maximum Power Point Tracking of Solar Photovoltaic Sources

OF THESIS Stargrazer One: A New Architecture for Distributed Maximum Power Point Tracking of Solar Photovoltaic Sources The yield from a solar photovoltaic (PV) source is dependent on factors such as light and temperature. A control system called a maximum power point tracker (MPPT) ensures that the yield from a solar PV source is maximized in spite of these factors. This thesis presents a novel implementation of a perturb and observe (PO) MPPT. The implementation uses a switched capacitor step down converter and a custom digital circuit implementation of the PO algorithm. Working in tandem, the switched capacitor step down converter and the custom digital circuit implementation were able to successfully track the maximum power point of a simulated solar PV source. This implementation is free of the overhead encountered with general purpose processor based MPPT implementations. This makes this MPPT system a valid candidate for applications where general purpose processors are undesirable. This document will begin by discussing the current state of MPPT research. Afterward, this thesis will present studies done to be able to use the chosen switched capacitor step down converter. Then the digital circuit PO implementation will be discussed in detail. Simulations of the architecture will be presented. Finally, experimental validation using a hardware prototype will be shown.
Evaluation of the Community Group Programme for Children & Young People: final report

The report presents findings from the evaluation of the Community Group Programme (CGP). The CGP is a 12-week psycho-educational, group work programme for children and young people who have experienced domestic violence. The Programme was developed in Canada and is being rolled out in England for the first time across 32 London boroughs. The programme is unique in working with children and their mothers concurrently and in a child-focused way. The study takes a theory-driven approach to evaluation. We employ a mixed method research strategy to answer questions of process (how does the CGP work? ), impact (does the CGP make a difference and, if so, what sort of difference), salience (does the CGP matter to children and mothers and if so, in what ways? ) and cost (what is the cost of CGP? ). The final report presents findings from questionnaires, interviews and focus groups with children, mothers and professionals.
Hemodynamics for Surgeons

The accurate description of blood flow through most atherosclerotic vessels still eludes scientists. Nevertheless, if peripheral vascular surgeons could grasp the way that bioengineers now understand hemodynamics, then clinical judgment, operative technique, and therapeutic results all might improve. Towards this goal, this text tidies up the previously empirical knowledge of clinicians and views it with a balance tilted toward science. The problem of communicating the complexity of bioengineering to nonmathematical readers is partially avoided by the frequent use of paragraphs containing "take home" clinical correlations. A certain amount of technical abstruseness and overcondensation remains, but in general, the bioengineering sections are readable and relevant. Take, for instance, a difficult question; whether distal arterial disease in a donor limb contraindicates a femoral-femoral graft. Instead of merely mentioning the possibility of an iliac steal syndrome, the authors first prove mathematically that distal donor limb disease should be significant only in the presence
