Interpolation and Decimation of Digital SignalsA Tutorial Review

The concepts of digital signal processing are playing an increasingly important role in the area of multirate signal processing, i.e, signal processing algorithms that involve more than one sampling rate. In this paper we present a tutorial overview of multirate digital signal processing as applied to systems for decimation and interpolation. We first discuss a theoretical model for such systems (based on the sampling theorem) and then show how various structures can be derived to provide efficient implementations of these systems. Design techniques for the linear-time-invariant components of these systems (the digital filter) are discussed, and finally the ideas behind multistage implementations for increased efficiency are presented.
Macroblock layer rate control algorithm of H.264/AVC

A new macroblock layer rate control algorithm was proposed based on a relatively simpler rate-distortion(R-D) model in order to reduce the computational complexity and improve the efficiency of H.264/AVC encoder.The algorithm adopted an adaptive method of bit allocation and encoding complexity regulation.Comparing to the previous algorithms used the predicted value of mean of absolute difference(MAD) in bit allocation and parameters update,the new algorithm made full use of the actual MAD and the similarity of encoding mode between two successive frames to ensured the smoothness of the output bit rate and the quality of the decoded picture.A skipped-mode pre-decision method was also proposed to further decrease the computational complexity.Experimental results showed that the proposed algorithm increased the encoding speed by about 10% in average while maintaining the similar peak signal-to-noise ratio(PSNR) and bit rate performance compared with the algorithm adopted in JVT-G012.
Editorial (to: Special Issue on Affective Brain-Computer Interfaces)

The research in brain–computer interfaces (BCI) has shown that brain activity can be used as an active/voluntary or passive/involuntary control modality in man–machine interaction. Until recently, BCI research aimed almost solely at improving the life of disabled persons in need of communication and physical interaction with their environment. Impressive results have been obtained where disabled persons have learned how to control an artificial limb or a wheelchair using their thoughts. Nowadays, however, we also see research aimed at using BCI for the general population. This is an interesting development. Why would a non-disabled user want to use BCI? Or, how could a computer use BCI in order to better support its user? In this Special Issue, our emphasis is on brain–computer interfacing that aims at detecting and using the mental or affective state of the user in order to adapt the interface to the user.

Observer-based state-feedback robust control for path following of autonomous ground vehicles

In this article, a robust H ∞ observer-based static state-feedback controller is designed for the path following of autonomous ground vehicles. The Takagi–Sugeno fuzzy modeling technique is used for modeling of vehicle dynamics with varying longitudinal velocity first. Then considering the high cost of direct lateral velocity measurement, an observer is designed to estimate the value of lateral velocity. Meanwhile, a robust controller is proposed to deal with the parameter uncertainties and external disturbances simultaneously, including the variation of the tire-cornering stiffness of both front and rear tires. Afterward, the condition of designing such an observer-based controller is transformed into the feasible problem of linear matrix inequalities. Numerical simulations using a high-fidelity and full vehicle model are performed based on a Carsim–Simulink joint platform. Simulation results under different conditions and comparison with other controller show that the proposed controller is effective irrespective of the variation in the road condition, the change in the vehicle longitudinal velocity and the external disturbances.
Simulation of MAV Dynamics

MAVs are a new and emerging area of aeronautics in which several stability and control issues remain unresolved. A number of these issues have arisen due to a lack of knowledge about the characteristics of flight in the Reynolds number region, in which MAVs operate. In an attempt to gain a better understanding of the phenomena associated with MAV flight, the aim of this project was to build a non-linear aerodynamic model of an MAV, built and flown by the University of Florida. The model was built using a block based programming language called Simulink. It was anticipated that by incorporating the non-linear aerodynamic effects, experienced by MAVs, into an already existing aerodynamic blockset, that the model would produce a realistic simulation of the flight dynamics of an MAV. The ultimate aim of the project was to produce a realistic and working aerodynamic model of the University of Florida’s MAV; which could be ‘flown’, using a conventional flight simulator. The outcome of the project has shown that it is possible to use a block based programming language, such as Simulink, in conjunction with a conventional flight simulator, to simulate a number of the non-linear aerodynamic effects which MAVs encounter during normal flight. This project has also shown that the accuracy of the simulation, of these non-linear effects, is highly reliant upon the ability to incorporate accurate experimental data from the aircraft, into the model. This report provides an outline of the method used to construct an aerodynamic model for the University of Florida MAV, and the method employed to subsequently modify the model to incorporate non-linear aerodynamic effects. The report also includes a brief discussion of some of the issues associated with the stability and control of the model, before providing validation of the model through results obtained during ‘flight tests’.
Crossword puzzles for chemistry education: learning goals beyond vocabulary

Chemistry is a technical scientific discipline strongly underpinned by its own complex and diverse language. To be successful in the problem-solving aspects of chemistry, students must master the language of chemistry, and in particular, the definition of terms and concepts. To assist students in this challenging task, a variety of instructional techniques need to be explored. In this study we have developed crossword puzzles to aid students in mastering chemical terminology via meaningful learning as opposed to rote memorisation. We have evaluated this tool for its effectiveness in study and revision. Specifically, we asked: (i) are crosswords effective as in-class and out-of-class revision tools? (ii) Is crossword performance (as a measure of the command of scientific vocabulary) predictive of problem-solving ability? The results demonstrated that crossword puzzles improve the ability of students to solve problems and, when used systematically, contribute to increases in learning. The findings are discussed in the context of information processing and meaningful learning.
Malnutrition and the Intelligence Quotient of Primary School Pupils in Jos, Nigeria

Background: Nigeria has one of the highest burdens of childhood malnutrition, thus, a large number of children are at risk of its far-reaching long term consequences. Although, the detrimental effect of malnutrition on the intellectual capability of children has been well documented, there is still a growing need to assess the extent of this cognitive deficit in our environment. This is with a view to providing a data base that may serve as an impetus for a more proactive attitude, geared towards the prevention of childhood malnutrition in Nigeria, and the West African sub-region in general. Aim: This study was set up to assess the relationship between the nutritional status of school children and their cognitive function. Study Design: This was a cross-sectional descriptive study carried out among 407 randomly selected primary school pupils between the ages of six to 12 years in Jos city, Plateau State, Nigeria. Methodology: A self-administered questionnaire was used to obtain socio-demographic details Original Research Article Adedeji et al.; BJMMR, 21(2): 1-13, 2017; Article no.BJMMR. 32504 2 from the parents. Nutritional status was determined by anthropometric methods, while IQ was assessed with Raven’s Standard Progressive Matrices (RSPM). Results: The overall prevalence of malnutrition was 35.4%, with thinness, underweight, stunting, overweight, and obesity accounting for 11.1%, 10.7%, 10.1%, 2.9% and 0.5% respectively. Optimal IQ was recorded among 37.3%, while suboptimal IQ was documented among 62.7% of the pupils. The prevalence of suboptimal intelligence was significantly higher in the stunted and underweight pupils; 83% of the stunted and 80% of the underweight pupils had suboptimal intelligence (p=.005, p=.014 respectively). Furthermore, low socio-economic class was observed to be associated with increased prevalence of suboptimal intelligence among the undernourished children (p<0.001). Conclusion: The high prevalence of under-nutrition, its association with suboptimal intelligence, as well as the detrimental role of low socio-economic class have been demonstrated in this study. More proactive measures, which should include health education and poverty alleviation, are required towards preventing childhood malnutrition. This will allow children attain their maximum intellectual potentials.
A Survey on Near Duplicate Web Pages for Web Crawling

Web Mining is the application of data mining techniques to extract knowledge from Web data. It is a keyword oriented search. The web is flooding with numerous copies of web documents so the search engines have to improve the performance of search results by eliminating the duplicate and near duplicate documents. The efficient identification of duplicate and near duplicate pages in a large repository is a significant problem with wide spread applications. In this paper the survey presents an up-to-date review of near duplicate detection algorithms used in web crawling.
Joint source-channel coding of images for channels with feedback

| We demonstrate that the end to end performance of a system for image transmission over noisy channels can be improved in the presence of a feedback channel. I. Introduction The problem of transmission of images over noisy channels has received much attention in the recent past 1, 2]. In this paper, we investigate the potential advantage of feedback from the receiver to the transmitter in image transmission. We restrict our attention to transmission over binary symmetric channels. Information theory dictates that the capacity of a binary symmetric channel does not increase with feedback 3]. Notwithstanding this asymptotic result, in many practical systems , useful improvements in the throughput can be obtained by use of Hybrid Automatic Repeat ReQuest (ARQ)/Forward Error Correction (FEC) protocols instead of pure FEC protocols 4, 5]. In this paper, we show how feedback can be eeectively used in an image transmission system employing an embedded image compression algorithm like that of Said and Pearlman 6] and a family of embedded channel codes like Rate Compatible Punctured Convolutional (RCPC) codes 4]. In Section II we describe the protocol for transmission. In Section III we set up the underlying optimization and describe the method of solution. In Section IV we discuss the results obtained by employing the solution from Section III and draw conclusions.

Initial Care for Patients with Severe Sepsis and Septic Shock: The Next ICU Quality Measure

In 2001, the landmark trial of early goal-directed therapy versus standard care for the treatment of severe sepsis and septic shock was published. The marked decrease in mortality with early recognition of sepsis and quantitative resuscitation revolutionized the treatment of patients with these conditions. Specific pieces of the early goal-directed therapy protocol have not been routinely adopted into bedside care; however, early administration of antibiotics, resuscitation with intravenous fluids, and attainment of hemodynamic stability to achieve end-organ perfusion have become the standard of care. To help ensure all patients receive optimal therapy at the first signs of severe sepsis or septic shock, the Surviving Sepsis Campaign has developed a core set of initial process steps and treatment goals grouped into a care bundle. Recognizing the benefit of early quantitative resuscitation on patient care, the National Quality Forum adopted a severe sepsis and septic shock care bundle that is similar to the Surviving Sepsis Campaign bundle. This care bundle has been adopted by the US Centers for Medicare & Medicaid Services, with reimbursement to be influenced beginning in 2017. The purpose of this review is to summarize evidence supporting the sepsis quality measure and care bundle and simplify key components of the care bundle where pharmacists can be impactful in ensuring optimal patient care and bundle compliance.
The AuthorAID project at INASP: building on a holistic approach to research communication

Through providing mentoring, training, resources and networking, the project supports early career researchers with writing up and disseminating their work. As part of INASP's PERii programme, the project both links and complements the other components of INASP's work. This paper outlines the AuthorAID project and explores its symbiotic relationship with INASP and its holistic approach to supporting research communication in developing countries.
Mining trauma injury data with imputed values

Methods for analyzing trauma injury data with missing values, collected at a UK hospital, are reported. One measure of injury severity, the Glasgow coma score, which is known to be associated with patient death, is missing for 12% of patients in the dataset. In order to include these 12% of patients in the analysis, three different data imputation techniques are used to estimate the missing values. The imputed datasets are analyzed by an artificial neural network and logistic regression, and their results compared in terms of sensitivity, specificity, positive predictive value and negative predictive value. Although there is little distinction between results for the three imputation methods for the overall dataset, the hot‐deck imputation method appears to give more accurate results than the model‐based or propensity score imputation methods, when comparing the subsets of cases including only those patients with imputed Glasgow coma score (GCS) scores. Results show that imputation does not reduce the overall predictive accuracy following a data‐mining analysis; demonstrating that all cases may be included when undertaking analysis of these trauma injury data.

Een systeembenadering voor onderzoek aan tripsbestrijding in de sierteelt onder glas: Een visiedocument vanuit onderzoek en praktijk

De Californische trips, Frankliniella occidentalis , is een van de grootste problemen in de sierteelt onder glas. Vanwege de sierwaarde van bloemen en potplanten worden maar zeer lage dichtheden van trips getolereerd. Dit maakt de biologische bestrijding erg lastig omdat de effecten hiervan vaak onvoldoende zijn om deze zeer lage tripsniveaus te halen. Verder hebben veel bestrijders, zoals roofmijten en roofwantsen, moeite om zich goed te vestigen in sierteeltgewassen. Het aantal selectieve chemische middelen is zeer beperkt. Middelen worden daardoor al snel te intensief gebruikt waardoor resistentie ontstaat en ze niet meer werken. Inzet van breedwerkende chemische middelen is niet wenselijk, omdat dit de biologische bestrijding van andere plagen zoals spint en wittevlieg verstoort. Om tot verbetering van bestrijding te komen is het belangrijk nieuwe beheersstrategieen te ontwikkelen vanuit een systeemaanpak waarbij maatregelen zoveel mogelijk complementair zijn. In dit rapport geeft zijn de knelpunten bij de bestrijding van trips beschreven en worden aanbevelingen gedaan voor verder onderzoek om tot een beter systeem van beheersing te komen. De aanbevelingen zijn ondergebracht is 4 strategische lijnen die beschreven zijn in de PPS (Publiek-Private Samenwerking) “Het nieuwe doen in plantgezondheid”, namelijk (1) weerbaar gewas, (2) robuuste weerbare teeltsystemen, (3) slimme en innovatieve technologieen en (4) effectief duurzaam middelenpakket.
Reaction Time and Attention after Closed Head Injury

This book is to form a trilogy with two others dealing with pathology of the trunk, the objective being to present cases suitable for didactic teaching in which computed tomograms and corresponding anatomical sections have been obtained. The main part of the book is, therefore, an atlas of computed tomograms, supplemented by a very brief text and few references. The computed tomograms are from second generation machines but are of reasonably good quality and they are generally accompanied by well displayed morbid anatomical sections. Many good teaching cases in which a fairly detailed comparison is possible, are included, and trainees in neurosciences should find these of value, but unfortunately the authors have included several cases, mainly among the acute conditions in which correlation is poor, usually because of too long an interval between CT and necropsy. The authors have not attempted to cover all the common CT manifestations of cerebral pathology and the approach is essentially anecdotal. The book is generally well produced, though occasionally incorrect reference is made in the text to the illustrations. Although the concept of this book was excellent, it is obvious that an even greater amount of material was necessary to allow the type of selection essential for its unqualified success; one hopes that this will be achieved in future editions.
Het dwaalspoor van de goede keuze : naar een effectiever model van (studie)loopbaanontwikkeling

In onderwijs- en arbeidsorganisaties bestaan grote problemen op het gebied van loopbaanontwikkeling. Veel scholieren en studenten vallen uit of switchen vroeg of vaak van opleiding. Veel arbeidsrelaties zijn voor werknemer of werkgever onbevredigend, maar duren toch voort. Uit onderzoek blijkt dat goede loopbaanbegeleiding helpt om dergelijke problemen te voorkomen of op te lossen. Hoewel hiermee in materiele en immateriele zin veel te verdienen valt, is goede loopbaanbegeleiding zeldzaam. Hoe komt dit? Er zijn de laatste jaren in het beroepsonderwijs grote investeringen in studieloopbaanbegeleiding gedaan. Waarom leveren deze inspanningen niet meer op? Waarom wordt in arbeidsorganisaties niet meer aan loopbaanbegeleiding gedaan? Hoe kan het beter? Dit zijn enkele van de vragen die in deze oratie aan de orde komen. Voor een deel wordt de stagnatie verklaard door de versnippering van het vakgebied. Daarnaast speelt het voortbestaan van hardnekkige, inadequate, maar dominante beelden een rol, zoals het beeld van 'de goede keuze', die het individu moet maken door informatie te verzamelen en na te denken. Wat is daar misleidend aan? Wat zijn de consequenties? Hoe kunnen we dit beeld bijstellen? Onder meer de risico's van reflectie komen aan de orde.
