On the choice of rational decimation systems for multidimensional signals

Rational decimation systems, which alter the signal sampling rates by a rational factor, can be used to reduce the data rate of bandlimited signals without loss of information. In the present work, this idea is extended from the one-dimensional case to the multidimensional (MD) case. Given an arbitrary support of bandlimited MD signals, it is shown how to find a rational matrix whose irreducible left matrix fraction description defines the decimation and expansion matrices required in the rational decimation system. It is also shown how to choose the filter in this system to completely eliminate image components and aliasing effects. This technique is also applied to MD signals that are bandlimited in hyperspherical supports. <<ETX>>
A 6800-μm2 Resistor-Based Temperature Sensor in 180-nm CMOS

A resistor-based temperature sensor has been realized in 180 nm CMOS for SoC thermal management applications. Occupying only 6800 μm<sup>2</sup>, it is the smallest resistor-based temperature sensor ever reported. This is achieved by employing a compact highly-digital VCO-based ADC. After a 2-point trim, the sensor achieves an inaccuracy of ±0.35 °C (3σ) in a temperature range from −35 °C to 125 °C. By achieving a resolution of 0.12 °C (rms) at 2.8kSa/s, it can track the fast thermal-transients in SoCs.
A WDR CMOS Image Sensor Employing In-pixel Capacitive Variation using a Re-configurable Source Follower for Low Light Applications

A wide dynamic range image sensor that uses a 5-transistor pixel architecture to provide user-programmable conversion gain enhancement for detection of low illumination signals is presented. The dynamic range enhancement is a result of periodic variation of the gate-bulk capacitance of the in-pixel source follower by re-configuring it as a MOS capacitor. The pixel is capable of providing standard integrated photo-signal in high illumination and amplified signal in low illumination. A prototype sensor containing a 64 × 64 array of the proposed pixels has been fabricated in AMS 0.35 /μm, 3.3 V CMOS technology to verify the operation. The 10 × 10 pixel has a 20.25% fill factor. The in-pixel signal amplification results in a dynamic range enhancement of 18 dB under low illumination condition and a conversion gain enhancement of 160 μV/e−.
A NEW STORAGE ARCHITECTURE FOR A FLASH-MEMORY VIDEO SERVER

During the past decade, there has been drastic growth in network traffics that are made from online views on video content in Internet. Owing to current high popularities of video streaming services such as YouTube, Netflix and portals’ UCC, such a trend is likely to be continuing in the next decade as well. For the successful proliferation of streaming services in the future, it is important to develop high-performance video servers that can fulfil bandwidth requirements of concurrently served video streams in a cost-effective way. To this end, we propose a video storage architecture using the SSD (solid state drive) as a cache layer. Since the SSD storage provides fast and uniform speed of random reads, it can work well with the EDF algorithm. To employ the EDF algorithm, the system time is divided into cycles and the bandwidth allocation is done by considering the scheduling periods and the number of flash blocks retrieved for serviced video streams. Since the bandwidth allocations of serviced video streams are managed within a full capacity of the scheduled SSD bandwidth, we can efficiently prevent undesirable hiccups of serviced video streams.
Life's Complexity Pyramid

How are the myriad components inside the cell connected together, enabling the cell to carry out its specific functions? In their Perspective, [Oltvai and BarabAisi][1] discuss two new studies ([Lee][2] et al ., [Milo][3] et al .) that investigate both biological networks of intracellular components and nonbiological networks such as the World Wide Web. They explain that all networks seem to be organized according to the same distinct principles.

Determining the Expected Length of Stay of Academic Staff in Various Grade Levels in a Polytechnic Institution in Nigeria Using a Markov Chain Approach

This study examined the transition into various grade levels of academic staff at Delta State Polytechnic, Otefe-Oghara using a markov chain approach. The staff transition for the various grade levels were found to be stationarity, since the 2 χ (co mputed) was obtained as 16.12 with a corresponding p-value = 0.1925 which fall on the acceptance region using . 05 . 0 = α It was found that an entrant on grade 1 (Assistant lecturer grade) is expected to stay for a period of 2 years and seven months in grade 1; an entrant on grade 2 (Lecturer III) is expected to stay for a period of 4 years and a month in grade 2; an entrant on grade 3 (Lecturer II) is expected to stay for a period of 3 years and 2 months in grade 3; an entrant on grade 4 (Lecturer I) is expected to stay for a period of 3 years and 4 months; an entrant on grade 5 (Senior Lecturer) is expected to stay for a period of 2 years and 11 months; an entrant on grade 6 (Principal Lecturer) is expected to stay for a period of 2 years and six months in grade 6; an entrant on grade 7 (Chief Lecturer) is expected to stay for a period of 4 years and 3 months in grade 7. It was concluded that staff in Principal Lecturer (grade 6) and Assistant Lecturer (grade 1) has less expected length of stay and also has greater chance of promotion than other grade level, hence, potential applicants are advised to apply for Principal Lecturer and Assistant Lecturer positions if vacancies exist in the Institution.
METABOLIC EFFECT OF FOS (FRUCTOOLIGOSACCHARIDE) IN TERMS OF GUT INCRETIN (GLP-1) GUT MICROFLORA AND WEIGHT REDUCTION IN OBESE ADULTS

In the recent years, obesity has increased beyond imagination. Appropriate dietary strategies which have the potential for weight loss demand patience and strong determination on part of the individual, however inclusion of functional foods like FOS that modulate gut hormones have a promising role in weight management. Methods: A randomized double-blind placebo-controlled trial was used as the study design wherein 65 obese adults were divided into experimental group (which was given 12 g of FOS) and a placebo group (which was fed with 12 g dextrose). The subjects were given the supplements daily for 12 week period. Their plasma samples were anlaysed for GLP-1 and microbial count in fecal samples were determined in terms of lactic acid bacteria, bifidobacteria and enteric pathogens. Hunger scores, dietary intake, and anthropometric parameters were assessed using standard techniques. Results: FOS supplementation resulted in improved plasma GLP-1 level by 17.0%. Significant improvement was observed in hunger score by 3.15% (p<0.05) along with reduction in dietary intake of energy (kcal) by 8%, carbohydrate (g) by 8%, protein (g) by 6% and fat (g) by 2%. Further, reductions were observed in total body weight (kg), BMI, % body fat and waist circumference (cm) levels by 4%, 1.06%, 4% and 1.66% respectively (p<0.001, p<0.001, p<0.001, p<0.05). The mean log counts of beneficial gut microbiota i.e. lactic acid bacteria and bifidobacteria increased significantly by 14 % and 10 % respectively along with 20% reduction in enteric pathogen. Conclusion: Daily intake of 12 gm FOS for 12 weeks helps in improving gut health and weight loss through increased satiety in obese individuals.
Off-Exchange Trading and Post Earnings Announcement Drift

Both theory and evidence are mixed regarding the impact on prices of trading on “dark” venues partially exempt from National Market System requirements. Theory predicts that price discovery improves as dark venues siphon noisy uninformed trades, but increased adverse selection reduces liquidity. Empirical studies, which focus on intraday inefficiency, also find contradictory results. We extend that literature to investigate the impact of dark trading on a longstanding inefficiency based on underreaction to quarterly earnings. We study a randomized controlled trial created by the “trade-at” rule of the SEC’s Tick Size Pilot Program that exogenously shocks dark trading. We supplement that with OLS and 2SLS regressions on a more representative Compustat/CRSP sample. All our results suggest that underreaction increases with dark trading, consistent with reduced liquidity limiting arbitrage. We contribute to the literatures on dark trading and inefficient processing of accounting disclosures, highlighting the role of advances in trading technology.

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO GRANDE DO SUL FACULDADE DE INFORMÁTICA PROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA DA COMPUTAÇÃO ABORDAGEM DE ANÁLISE DO TEMPO DE RESPOSTA PARA TESTE DE DESEMPENHO EM APLICAÇÕES WEB

Technology advances have allowed software systems to become more common in our society solving different types of problems we face everyday. This widespread use of software systems brought about some bigger and more complex solutions, which resulted in more systems that can fail. Furthermore, two important aspects in the software development process are being considered in every project: time to delivery and product quality. Since products have to be delivered faster, some faults may reside in the product and that could cause unforeseeable costs. In this scenario it is fundamental that the testing activity become one of the most important parts of the software development process to guarantee the quality of the final product. However, the testing activity is usually very expensive and time consuming, since most of the time it is executed manually. To improve that, Model Based Testing (MBT) has been used lately to generate testing artifacts automatically. These artifacts are usually extracted from the system model. This has helped to reduce the cost of testing, since the time to generate and execute tests can be reduced. Therefore, the main contribution of this work is to investigate how MBT can be applied for performance testing, i.e. how to include timing constraints in UML (Unified Modeling Language) diagrams and based on those constraints to execute the tests and verify whether the constraints are met or not. Another contribution of this work, is the setting of Service Level Agreements, i.e. set parameters to verify whether a system delivery answers based on pre-determined values. We applied our strategy to two sample applications, i.e. TPC-W and Skills, and measured their execution time using the LoadRunner Tool. Furthermore, we applied our whole strategy also to a complete case study, i.e. ChangePoint, and discuss some of our results.
Generating Learning Algorithms: Hidden Markov Models as a Case Study

This thesis presents the design and implementation of a source code generator for dealing with Bayesian statistics. The specific focus of this case study is to produce usable source code for handling Hidden Markov Models (HMMs) from a Domain Specific Language (DSL). Domain specific languages are used to allow domain experts to design their source code from the perspective of the problem domain. The goal of designing in such a way is to increase the development productivity without requiring extensive programming knowledge.

Semantic-Based Three-Dimensional Modeling of Virtual Reality Scenes

Virtual reality scenes three-dimensional modeling usually is constructed on the basis of learning with virtual data, and learning behavior is too dependent on virtual data.It is difficult to quickly and accurately reflect characteristics of 3D modeling in virtual reality, and learning complexity is higher. In this paper, a method of virtual reality scenes three-dimensional modeling based on semantic was presented on the basis of analysis of the virtual scenes modeling methods. The modeling system architecture using the method is divided into physical model libraries, three-dimensional model semantic knowledge base, semantic-based visual modeling and scene graph automatically generation modules. The experimental results show that the detection performance is better than the results of the three-dimensional modeling based on virtual data, and the system increases flexibility and usability of the three-dimensional modeling,
Engaging with young children’s voices: implications for practitioners’ pedagogical practice

ABSTRACT The paper seeks to extend the knowledge and understanding of how engaging with young children’s voices in a meaningful way, can alter practitioners’ pedagogical practice and thus create environments for learning that are more inclusive. It draws on the findings of a research study that explored practitioners’ (teachers, nursery nurses and teaching assistants) views about engaging with young children’s voices of perceived notions of inclusion in pedagogical activities in the early years classes of two schools in the North of England. It adopted a qualitative methodological approach that operates within constructivist and interpretivist paradigms. The study revealed that practitioners retain some resistance to responding to the voices of young children and that internal and external pressures influence their decision-making. Moreover, it signifies the necessity for greater emphasis on the importance of engaging with children’s voices in the training of newly qualified teachers, and the ongoing professional development for all practitioners in early childhood education.
Modeling and analysis of the performance of exascale photonic networks

Photonics technology has become a promising and viable alternative for both on‐chip and off‐chip interconnection networks of future Exascale systems. Nevertheless, this technology is not mature enough yet in this context, so research efforts focusing on photonic networks are still required to achieve realistic suitable network implementations. In this regard, system‐level photonic network simulators can help guide designers to assess the multiple design choices. Most current research is done on electrical network simulators, whose components work widely different from photonics components. In this work, we summarize and compare the working behavior of both technologies which includes the use of optical routers, wavelength‐division multiplexing and circuit switching among others. After implementing them into a well‐known simulation framework, an extensive simulation study has been carried out using realistic photonic network configurations with synthetic and realistic traffic. Experimental results show that, compared to electrical networks, optical networks can reduce the execution time of the studied real workloads in almost one order of magnitude. Our study also reveals that the photonic configuration highly impacts on the network performance, being the bandwidth per channel and the message length the most important parameters.
Tips and Hints for an Effective COSMIC Learning Process Derived from Industrial Training

As a technology transfer centre specialising in IT, we have been training companies to use the COSMIC estimation methodology for several years. This paper reports a retrospective look at a number of recurrent issues that occurred during those training sessions across a large variety of business domains, company sizes and maturity levels. Some of these issues are related to the COSMIC method itself or to the functional size measurement in general, while others have their roots in other fields like project management or requirements engineering. Failing to address these issues in an adequate way may prevent from meeting the training goals and the successful adoption of the COSMIC method. We also report how we have designed our training to handle most of these issues and to capitalize on returns from trainees. We will explain the most recurrent issues and give some hints and tips to design and conduct training.
Improved Content Aware Image Retargeting Using Strip Partitioning

Based on rapid upsurge in the demand and usage of electronic media devices such as tablets, smart phones, laptops, personal computers, etc. and its different display specifications including the size and shapes, image retargeting became one of the key components of communication technology and internet. The existing techniques in image resizing cannot save the most valuable information of images on display devices with different resolutions. Seam carving is a standard technique for content-aware resizing of images and videos with negligible distortion. However, seam carving resize high-resolution videos and high quality images with high computational complexity; this limits its real-time applications. In this paper, we present a novel approach to reduce seam carving process time. In the proposed technique, the image was split into three equal parts: upper-middle-lower (or right-middle-left) using horizontal or vertical strips. The middle strip was analyzed by original seam carving technique. For other strips (upper-lower), the seam was obtained employing Dijkstra fixed start point technique. In our proposed technique, unlimited Dijkstra depth search was replaced with a limited depth search. It enhances the computational efficiency of Dijkstra technique for the upper and lower strips. The experimental results showed much better computational efficiency than the current enhanced seam carving techniques. These results indicate that computational complexity is superior, while still maintaining the output quality of the original seam carving method.
Sexuellt beteende hos bonoboapor (Pan paniscus) och evolutionära fördelar med icke-reproduktiv sexualitet

Bonoboapan (Pan paniscus) erkandes ar 1929 som en egen art och hade innan dess ofta misstagits for schimpans (Pan tryglodytes). Arterna paminner om varandra till utseendet, men skiljer sig at i beteende. Detta ar fascinerande med tanke pa att de delar nastan identiska genom. En aspekt som skiljer de tva arterna at ar det sexuella beteendet. Bonoboapor ar hypersexuella och interagerar sexuellt i manga fler sammanhang an schimpanser. Det sexuella beteendet paverkar den sociala strukturen. Honor knyter an till varandra genom genito-genital rubbing, vilket ar extra viktigt mellan nya yngre honor i en grupp och aldre honor. Genom att interagera sexuellt med aldre hogt uppsatta honor befaster den nya honan sin plats i gruppen och okar sin sociala status. En honas formaga att knyta an till andra honor ar aven avgorande for hennes son, vars status beror pa moderns status. Sammanhallningen ar ocksa stark mellan hanar och honor, formodligen tack vare honornas kontinuerliga sexuella mottaglighet. Sjalvklart fyller sexualiteten en reproduktiv funktion. Brunstcykeln varar i 35 dagar och atfoljs av en lika lang period av perineal svullnad. Denna ar som storst i 13 dagar och signalerar att honan ar sexuellt mottaglig. Svullnaden ar forlangd, det vill saga den stracker sig utanfor agglossningen, och ar darfor inget sakert tecken pa att hon ar redo for befruktning. Honan blir konsmogen mellan 6 och 11 ars alder och far sin forsta avkomma i 15-arsaldern. Repertoaren av sexuella beteenden ar stor. Mellan honor forekommer som sagt genito-genital rubbing, det vill saga honorna gnider sina genitalier mot varandra. Hanar har ocksa genital kontakt i form av ventro-dorsal bestigning, rump-rumpkontakt och ventro-ventral omfamning. Kopulation och bestigning ar de vanligaste beteendena mellan hanar och honor. Manuell stimulans av varandras genitalier har ocksa observerats. Om unga individer ar delaktiga forekommer ett flertal andra beteenden. Det sexuella beteendet har manga icke-reproduktiva syften. Efter en konflikt mellan tva individer kan de forsonas eller fa trost av utomstaende individer i form av genito-genital rubbing, annan genital kontakt eller kopulation. Detta sanker stressnivaerna, vilket yttrar sig genom att den utsatta individen kliar sig mindre. Sexuell kontakt kan aven reducera sociala spanningar som kan uppsta vid till exempel fodointag och trangsel. Ytterligare syften ar anknytning till andra individer, forhandling om resurser och social lek. Icke-reproduktiv sexualitet verkar utover ovanstaende syften aven ha evolutionara fordelar sa som faderskapsforvirring: Den forlangda perineala svullnaden innebar att det inte finns nagra visuella tecken som signalerar nar honan har agglossning och att honor och hanar kopulerar under hela brunstcykeln. Detta skapar forvirring om vem som ar fadern och gor infanticid kontraproduktivt. Bonoboapan ar ett lysande exempel pa hur icke-reproduktiv sexualitet har utvecklats vid sidan om reproduktiv sexualitet och vilka viktiga funktioner det fyller, bade i den dagliga tillvaron och evolutionart.
