Data access optimized applications on the GPU using NVIDIA CUDA

This work is an attempt to address the problem of bandwidth limited performance of data intensive GPGPU applications. Performance limited by memory bandwidth is common issue faced by general data intensive HPC applications. In case of the GPU, this problem is more pronounced owing to the unique architecture. This problem has been tackled by optimizing basic data rearrangement operations on the GPU. In this direction, methods and approaches have been identified and formulated for optimizing data rearrangement in general on GPU architectures. These are employed to develop near optimal and generic GPU kernels for a set of data rearrangement operations. In particular a library of GPU kernels has been developed, for operations that involve rearranging a generic m-dimensional data into n-dimensions. These kernels have been hand-tuned for maximum throughput, equaling upto 90% of the bandwidth utilization of the intrinsic memcpy function. These kernels are developed as templatized generic implementations allowing for their seamless integration into other existing applications. The target GPU architectures considered in this work are NVIDIA Tesla c1060 and NVIDIA Tesla c870 and kernels have been developed using NVIDIA CUDA. All the kernels achieve or surpass best known performance in terms of bandwidth utilization. Furthermore, as a case study of a simple CFD Navier-Stokes based flow solver has been developed for the GPU, incorporating the optimal data rearrangement principles. This has been tested for the case of a 2D lid driven cavity flow. The GPU implementation is comprehensively compared with optimal serial and parallel CPU implementations on an Intel Nehalem X5550 platform. A maximum speedup of 252x as compared to the serial code on the CPU and 13x as compared to the parallel CPU code (16 MPI processes on 8 cores of 2 Quad Nehalem X5550), has been attained.
Review On Google Android a Mobile Platform

At present smart phone usage is increasing dramatically. Globally, if a usage comparison can be carried out between cell phone and smart phone devices. Smart phone is a personnel device which provides entertainment, information, making call and writing SMS. Customization makes cell phone a smart phone (installation and uninstallation of application). The increasing importance of smart phone devices has triggered intense competition among technology giants to capture the bigger market share for mobile platform. So Google launched Android, an open source mobile platform for smart phone devices consisting of a Linux Kernel, runtime environment, development framework, libraries and key applications. Since its official public release, Android has captured the market. This paper intends to explore conventional approach of mobile application execution, an approach of mobile application execution in Android & comparison between Android OS (Google), iOS (Apple) & Blackberry OS (RIM).
Copy move Forgery Detection Approaches: A Survey

Copy-move forgery detection is one of the most popular image forgery technique in which a part of a digital image is copied and pasted to another part in the same image with the intension to make an object “disappear” from the image by covering it with a small block copied from another part of the same image. Hence, the main task of copy-move forgery detection is to detect image areas that are same or almost similar within an image. These method in general use two approaches namely key-point based and block based. This paper provides a review of copy move forgery detection on various techniques. Keywords: Copy move forgery, Lexicographical Sorting, Digital Image Forgery, Duplicated Region.
AR Magic Lenses: Addressing the Challenge of Focus and Context in Augmented Reality

In recent years, technical advances in the field of Augmented Reality (AR), coupled with the acceleration in computer and graphics processing power, have brought robust and affordable AR within the reach of the wider research community. While the technical issues of AR remain heavily researched, there is also a growing amount of work on user interface development and evaluation, heralding the convergence of traditional Human Computer Interaction (HCI) and AR. Magic Lenses are 2D interface components that provide alternative representations of objects seen through them. In this way, they can be used to provide Focus and Context in the interface, especially when visualising layered information. There are very few, if any, formal evaluations to guide the development of lens-based interfaces. This thesis describes the development and evaluation of Magic Lenses as a tool for AR interfaces. The work starts with a comprehensive survey of many Focus and Context techniques, which are classified based on the way they present views to the users { for example, a Magic Lens is a spatially separated multiple view technique. A formal evaluation of 2D Magic Lenses in a GIS scenario found that users strongly preferred the lens-based interaction technique to others, largely because it reduced the effort of interaction. Accuracy was high with the lenses, but a simple “global view” interface allowed significantly faster performance. This positive result motivated further work on Magic Lenses within AR, where the lens metaphor can reinforce the tangible interaction methods that link virtual and real content. To support rapid exploration of interaction alternatives with AR Magic Lenses, I describe the design and architecture of osgART, an AR development toolkit that is available to the research community as open-source software. Object selection and manipulation is a fundamental interaction requirement for all AR interfaces, and I establish an empirical foundation of performance in this task with a variety of AR interaction techniques, including Magic Lenses. Results show that performance with all techniques is successfully modelled by Fitts’ Law, and that Magic Lenses outperformed other techniques. Finally, I examine new interaction techniques based on Magic Lenses, particularly a Flexible Sheet Lens, which allows concurrent bimanual specification of multiple parameters within the visualisation.
Describing Food Availability in Schools Using Different Healthy Eating Guidelines: Moving Forward with Simpler Nutrition Recommendations.

PURPOSE Internationally, there is debate on whether a nutrient or a food-based approach to policy is more effective. This study describes the food/beverage availability in schools in Nova Scotia through a comparison of a traditional nutrient classification ("Maximum/Moderate/Minimum"), currently used in the provincial school policy and a simplified food-based system ("Core/Extra"). METHODS School food environment audits were conducted in schools (n = 25) to record the food and beverages available. Registered dietitians categorized information using both the nutrient-based and simplified food-based classification systems. Number and percent in each category were described for items. RESULTS Food and beverage items consisted of breakfast, lunch, snacks, beverages, and vending of which 81% were permissible by the policy, whereas only 54% were categorized as Core. Many snacks and vending items classified as Extra fell within either Moderate (45% and 35%, respectively) or Minimum (29% and 33%, respectively) categories. CONCLUSIONS Dietitians have a role to support interpretation of classification systems for school nutrition policies. The nutrient-based classification used in the policy permitted some items not essential to a healthy diet as defined by the Extra food-based classification. However, the food-based Core/Extra categorization had less detail to classify nutrients.
An Improved Singular Value Decomposition Recommender Algorithm Based on User Trust Relationship

Collaborative filtering is one of the most widely used recommender algorithms, whereas it is suffering the issues of data sparsity. Recommender algorithms based on trust perform better in alleviating data sparsity. However, there remain shortages in the process of mining trust relation in specific algorithms, which limit the improvement of prediction accuracy. To address this problem, the paper proposes an improved singular value decomposition algorithm, trying to integrate truster-specific and trustee-specific information and the implicit feedback of each when generating predictions. Experiments on the Epinions dataset show that the proposed algorithm performs better than state-of-the-art recommender algorithms in prediction accuracy.
Analysis and PCB Design of Class D Inverter for Wireless Power Transfer Systems Operating at 13.56MHz

This paper presents the analysis and PCB design of a class D inverter for wireless power transfer systems operating at 13.56 MHz. The effects of parasitic inductance on the switching performance of MOSFETs, transfer efficiency of WPT systems, and power loss are analyzed. At high frequencies, the print circuit board (PCB) design is very critical because it control the parasitic elements on the circuit. This study proposes an improved PCB design that can provide a 23.4% decrease in parasitic inductance over the conventional PCB design.

Recent Developments on Introducing a Historical Dimension in Mathematics Education: Teaching with Primary Historical Sources: Should it Go Mainstream? Can it?

Many are now teaching mathematics directly with primary historical sources, in a variety of courses and levels. How far should this be taken? Should we adapt or redesign standard courses to a completely historical approach, chiey from primary sources? If so, what are the obstacles to achieving this? Materials? Instructor attitudes? What should and can we do about such things?
CritIQ: A Mobile Critique App for Undergraduate Communication Design Learners

ABSTRACT Critical discourse is one of the principal critical thinking strategies that emerging communication design learners must learn from their classroom experiences. The investigator contends it is necessary and possible to extend these critical interactions beyond the classroom by exploiting the affordances of mobile technology. CritIQ, the proposed mobile application described in this paper extends, motivates, enables, and sustains remote synchronous and asynchronous critical thinking and conversations among undergraduate communication design learners (throughout the design process after the solution/idea has been secured) when no design instructor is present. The investigator shares the research methodology that was employed to conceptualize the mobile application. They explain how a codesign activity informed the design of CritIQ's meaningful features and innovations and how these in turn support the needs of learners who must learn to effectively critique their work, as well as the learning objectives of their design instructors.
Achieving power efficiency through minimum cycle time in digital signal processor design

Fast microprocessors exploit instruction level parallelism and high clock frequency. On the other hand, power dissipation is reduced by lowering the supply voltage and consequently increasing the clock cycle time. This paper presents a DSP architecture which targets a simple, low-cost and ultra-high frequency implementation, showing that this choice leads to high power efficiency in terms of dissipation with constrained performance. The design reduces the cycle time by a combination of instruction set as well as microarchitecture design choices. The architecture performance is extensively evaluated by means of instruction level simulation of standard DSP benchmarks and cycle time estimation. A theoretical analysis of the power efficiency is also provided.
Risiko-Screening im Handballsport – Welche funktionellen Tests sind sinnvoll?

Zusammenfassung Hintergrund Ein Weg zur optimierten Verletzungsprophylaxe ist der Einsatz funktioneller Testbatterien im Sport. Auf Basis dieser Ergebnisse können korrigierende Übungen empfohlen werden, mit dem Ziel die Defizite zu beheben. Ziel dieser Untersuchung war es, Ergebnisse ausgewählter funktioneller Tests mit dem Auftreten von Verletzungen bei jugendlichen Handballspielern zu vergleichen. Material und Methoden An dieser Studie nahmen 31 Spieler aus den Nachwuchsmannschaften eines Handballbundesligisten teil. Vor Beginn der Rückrunde absolvierten alle Spieler den Functional-Movement-Screen, Y-Balance-Test, Front-Hop-Test, Side-Hop-Test und Square-Hop-Test. Alle Verletzungen, die nach der Testung aufgetreten sind, wurden bis zum Abschluss der Saison dokumentiert. Ergebnisse Innerhalb des Untersuchungszeitraums wurden 4 Nicht-Kontakt-Verletzungen und 4 Kontakt-Verletzungen registriert. Spieler, die eine Nicht-Kontakt-Verletzung erlitten haben, zeigten im Side-Hop-Test eine Seitensymmetrie von 78 % (Unverletzte und Kontakt-Verletzungen > 85 %) und im Y-Balance-Test einen Composite-Score von 87 % (Unverletzte und Kontakt-Verletzungen > 90 %). Für den Functional-Movement-Screen, die Front- und Square-Hop-Tests konnten keine deutlichen Unterschiede zwischen verletzten und unverletzten Spielern festgestellt werden. Schlussfolgerung Die Ergebnisse dieser Studie weisen darauf hin, dass innerhalb von Funktionsuntersuchungen im Handball neben Low-Threshold-Tests auch Testverfahren aus dem High-Threshold-Bereich angewendet werden sollten. Besonders geeignet für Handballsportler scheinen nach den Erfahrungen dieser Untersuchung der Y-Balance-Test und der Side-Hop-Test zu sein.
A switched-current incremental A/D converter

This paper presents the implementation of an incremental A/D converter designed as part of the signal-conditioning circuitry of a pressure sensor interface. For technological compatibility, the switched-current technique was chosen, since it does not need double polysilicon CMOS process. The low precision of the SI technique have been partially overcome by using a offset cancellation algorithm and circuit enhancements. Resolutions of up to 10 bits are achieved for a 1 MHz clock frequency through electrical simulations. A 1 /spl mu/m CMOS prototype is being tested and some experimental results are given.
A Study on Game Bot Detection Using Self-Similarity in MMORPGs

ABSTRACT Game bot playing is one of the main risks in Massively Multi-On line Role Playing Games(MMORPG) because it damages overall game playing environment, especially the balance of the in-game economy. There have been many studies to detect game bot. However, the previous detection models require continuous maintenance efforts to train and learn the game bots' patterns whenever the game contents change. In this work, we have propos ed a machine learning technique using the self-similarity property that is an intrinsic attribute in game bots and automa ted maintenance system. We have tested our method and implemented a system to major three commercial games in South K orea. As a result, our proposed system can detect and classify game bots with high accuracy.

Multipath delay spread and signal level measurements for indoor wireless radio channels at 62.4 GHz

This paper reports the 62.4 GHz fixed wideband propagation measurements undertaken in six different LOS indoor environments (corridors and rooms) inside three buildings. Measurement analyses are presented in respect of static RMS delay spreads and received signal level. Uniformity of delay spread was observed for all the cases investigated. A correlation is observed with the static delay spread increasing monotonically with increasing base-portable receiver antennas separation. For low values of the received signal level the delay spread values are relatively high and vice-versa. It has been observed that important indoor radio channel characteristics are determined by the principal structure of the environments and do not depend significantly on minor details like furniture and room fixtures.
The Protection Technology of Script-Based Cyber Attack

Recent web-based cyber attacks are evolving into a new form of attacks such as private information theft and DDoS attack exploiting JavaScript within a web page. These attacks can be made just by accessing a web site without distribution of malicious codes and infection. Script-based cyber attacks are hard to detect with traditional security equipments such as Firewall and IPS because they inject malicious scripts in a response message for a normal web request. Furthermore, they are hard to trace because attacks such as DDoS can be made just by visiting a web page. Due to these reasons, it is expected that they could result in direct damages and great ripple effects. To cope with these issues, in this article, a proposal is made for techniques that are used to detect malicious scripts through real-time web content analysis and to automatically generate detection signatures for malicious JavaScript.
Principled Probabilistic Methods To Integrate Information From The Query Workload Into The Data Annotation Process

The aspiration of CADS is to persuade and inferior the cost of crafting adequately interpreted documents that can be right away helpful for usually issued partially prearranged enquiries. Our solution ambition is to promote the annotation of the documents at creation time at the same time as the creator is still in the “document generation” segment even nonetheless the procedures can also be used for post generation document annotation. In our circumstances the author produces a new document and uploads it to the ordnance. We suggest Collaborative Adaptive Data Sharing platform (CADS) which is an “annotate-as-you create” communications that makes easy field data annotation. An explanation payment of our system is the straight use of the enquiry workload to straight the annotation processes in addition to exploratory the content of the document. In other words we are annoying to prioritize the annotation of documents toward generating characteristic values for attributes that are frequently used by querying users.
Die Bedeutung der intraoperativen optischen Kohärenztomografie (MI-OCT) bei der Behandlung von Hornhautdystrophien

Zusammenfassung Hintergrund Die chirurgische Behandlung von Hornhautdystrophien entwickelt sich mit zunehmender Anwendung von lamellären Techniken der Hornhauttransplantation rasant weiter. War vor einigen Jahren noch die penetrierende Keratoplastik der Goldstandard zur Therapie einer Vielzahl von Dystrophien, so können heutzutage selektiv die betroffenen Schichten der Hornhaut ersetzt oder mittels Lasertechnik abladiert werden. Einen besonderen Stellenwert nimmt für diese Verfahren die optische Kohärenztomografie ein, die neuerdings auch in Operationsmikroskope integriert sein kann (MI-OCT). Methoden Literaturübersicht aus PubMed und Google.scholar. de ergänzt mit eigenen Bildgebungsdaten. Ergebnisse Die MI-OCT ermöglicht das intraoperative Echtzeit-Monitoring unterschiedlicher ophthalmochirurgischer Prozeduren wie der tiefen, anterioren lamellären Keratoplastik, der Descemet-Membran-Endothel-Keratoplastik (DMEK), aber auch minimalinvasiver Verfahren wie der phototherapeutischen Keratektomie (PTK). Darüber hinaus ermöglicht sie eine Evaluation der Hornhaut wie auch der Vorderkammer, insbesondere in Situationen einer getrübten Hornhaut. Schlussfolgerung Die mikroskopintegrierte intraoperative optische Kohärenztomografie (MI-OCT) stellt eine sinnvolle Ergänzung zum normalen Operationsmikroskop dar. Sie ist insbesondere bei bereits stark getrübten Hornhäuten dem alleinigen Operationsmikroskop überlegen und stellt gerade bei neuartigen lamellären Transplantationsverfahren eine sinnvolle Ergänzung dar. Randomisierte prospektive Studien sind nötig, um die erhöhte Sicherheit und gesteigerte Effektivität durch den Einsatz der MI-OCT bei verschiedenen Indikationen zu belegen.
Equivalent open-loop system for a general class of sigma-delta modulator configurations

This paper presents an equivalent open-loop system for the exact analysis and characterization of a general class of sigma-delta (/spl Sigma/-/spl Delta/) modulator configurations. This open-loop system is based on the exploitation of the closed-form solution of the granular error (i.e. the error under no-overload operation) associated with the constituent coarse quantizer. The proposed open-loop system is subsequently applied to the determination of the signal-to-quantization noise ratio for the class of /spl Sigma/-/spl Delta/ modulator configurations under consideration. The results are illustrated through their application to a triple-loop /spl Sigma/-/spl Delta/ modulator for DC as well as AC input signals.
