Optimization of a space vector control using MOAM algorithm and extended Kalman filter

This paper proposes a new application of parameter estimation for induction motors. Induction motor is described by non-linear differential equations and an Extended Kalman Filter (EKF) estimates three parameters needed for the control (rotor resistance, stator resistance and magnetising inductance). A Modified Random Optimisation Method, MOAM, is used to optimize the covariance matrix in Extended Kalman Filter, rotor and stator autoinductances, friction factor and moment of inertia. It is used to achieve the best performance in the Vector control. Simulation studies on a field oriented controller (FOC), under different variations on the parameter model, and experiments with 5.5 kW motor are presented.
Response to the NCEPOD report: development of a care bundle for patients admitted with decompensated cirrhosis—the first 24 h

Recently, there has been a significant increase in the prevalence of chronic liver disease in the UK, and as a result, hospital admissions and deaths due to liver disease have also increased. The 2013 National Confidential Enquiry into Patient Outcome and Death (NCEPOD) of patients with alcohol-related liver disease (ARLD) found that less than half the number of patients who died from ARLD received ‘good care’, and avoidable deaths were identified. In order to improve the care of patients admitted with ARLD, the NCEPOD report recommended that a ‘toolkit’ for the acute management of patients admitted with decompensated ARLD be developed and made widely available. As a result, we have developed a ‘care bundle’ for patients admitted with decompensated cirrhosis (of all aetiologies) to ensure that effective evidence-based treatments are delivered within the first 24 h. This care bundle provides a checklist to ensure that all appropriate investigations are undertaken when a patient with decompensated cirrhosis presents and provides clinicians with clear guidance on the initial management of alcohol withdrawal, infection, acute kidney injury, gastrointestinal bleeding and encephalopathy. The first 24 h are particularly important, as early intervention can reduce mortality and shorten hospital stay, and specialist gastroenterology/liver advice is not always available during this period. This review will discuss the care bundle and the evidence base behind the treatment recommendations made.
OCL-BodyScan: A Case Study for Application-centric Programming of Many-Core Processors

Application development for many-core processors is predominately hardware-centric: programmers design, implement, and optimize applications for a pre-chosen target platform. While this approach may deliver very good performance, it lacks portability, being inefficient for applications that aim to use multiple architectures or large-scale parallel platforms with heterogeneous many-core nodes. In this work, we focus on application portability. Therefore, we propose an application-centric approach for developing parallel workloads for many-cores, and we make use of OpenCL to preserve portability until the very last optimization stages. We validate our application-centric approach using 3D body scan, a data intensive application with soft real-time constraints. Thus, we design and implement OCL-body scan (the portable OpenCL-based version of 3D Body scan), and we evaluate its performance on three families of platforms - general purpose multi-cores, graphical processing units, and the Cell/B.E. Our experiments show that our application-centric strategy enables portability and leads to good performance results. Additionally, typical platform-specific optimizations can be applied in the final implementation stages, leading to performance results similar to those obtained using the native tool-chains.
A Context-Aware Recommender System Framework for IoT based Interactive Digital Signage in Urban Space

Digital Signage (DS) is one of the popular IoT technologies deployed in the urban space. DS can provide wayfinding and urban information to city dwellers and convey targeted messaging and advertising to people approaching the DS. With the rise of the online-to-offline (O2O) mobile commerce, DS also become an important marketing tool in urban retailing. However, most digital signage systems today lack interactive feature and context-aware recommendation engine. Few interactive digital signage systems available today are also insufficient in engaging anonymous viewers and also not considering temporal interaction between viewer and DS system. To overcome the above challenges, this paper proposes a context-aware recommender system framework with novel temporal interaction scheme for IoT based interactive digital signage deployed in urban space to engage anonymous viewer. The results of experiments indicate that the proposed framework improves the advertising effectiveness for DS system deployed in public in urban space.
Elements of Light-cured Epoxy-based Dental Polymer Systems

The greatest problem with current dental composite systems is their polymerization shrinkage. Extensive work is being done by many investigators to alleviate this problem. Our approach has been to examine epoxy- and spiro-orthocarbonate (SOC)-based resins. The hypothesis to be tested in this study was that the cure characteristics of experimental visible-light-cured epoxy resin systems are governed by the types and concentrations of co-reactants and activators. Resin samples containing onium salt initiators and a thiozanthone sensitizer were successfully cured by means of either an experimental visible-light irradiation system or a commercially available dental lamp. Test resins consisted of di-epoxies alone or in combination, epoxy mixtures in combination with an SOC, or an epoxy in combination with a caprolactone-derived polyol. Significant findings were as follows: (a) Resins containing the SOC had longer cure times than their counterparts; (b) the optimum ratios of epoxy to polyol for most rapid cure were 50:50 or 60:40 under conditions tested; (c) resins containing TONE 305 polyol generally were faster to cure than those containing no polyol, or TONES 201 or 310; and (d) a resin mixture was found that had a cure time of 1 to 3 min when irradiated with a commercial dental lamp. Based on this exploratory study, it should be possible for clinically relevant cure times to be achieved for visible-light-cured epoxy-based resins by careful manipulation and optimization of key elements.
Complete canthi removal reveals that forces from the amnioserosa alone are sufficient to drive dorsal closure in Drosophila

Laser microsurgery and computer tracking of embryo structures indicate that the morphogenetic process of Drosophila dorsal closure requires only forces generated by the amnioserosa tissue. Forces generated by both “zipping” of epidermal tissue at the canthi corners and the resulting actomyosin purse string curvature are not necessary for closure.
Pencil: A Petri Net Speci(cid:12)cation Language for Java

The Pencil language is designed to help developers quickly prototype, simulate and build their systems using the formal language of Petri nets. Using Pen-cil, it is possible to specify and model a system and to put abstract models directly into action. Pencil compiles Petri net speci(cid:12)cations into objects de(cid:12)ned in the Java language, allowing Pencil to seamlessly integrate with real-world enterprise applications. Pencil is designed to be simple, intuitive, (cid:13)exible, formal, powerful and highly modular. The formal properties allow theoreticians to leverage the rich literature on Petri nets in modelling and designing systems. The modularity and Java integration allows working programmers to combine veri(cid:12)ed modules with no additional work. The simple syntax (similar to Java and C++) and automatic translation mechanism help reduce implementation errors. Pencil extends the mathematical model of Petri nets so that application behavior can be described simply and economically. This combination of features make Pencil a good bridge between modeling and implementation.
DNA alterations in the tumor genome and their associations with clinical outcome in prostate cancer

Although most prostate cancer (PCa) cases are not life-threatening, approximately 293 000 men worldwide die annually due to PCa. These lethal cases are thought to be caused by coordinated genomic alterations that accumulate over time. Recent genome-wide analyses of DNA from subjects with PCa have revealed most, if not all, genetic changes in both germline and PCa tumor genomes. In this article, I first review the major, somatically acquired genomic characteristics of various subtypes of PCa. I then recap key findings on the relationships between genomic alterations and clinical parameters, such as biochemical recurrence or clinical relapse, metastasis and cancer-specific mortality. Finally, I outline the need for, and challenges with, validation of recent findings in prospective studies for clinical utility. It is clearer now than ever before that the landscape of somatically acquired aberrations in PCa is highlighted by DNA copy number alterations (CNAs) and TMPRSS2-ERG fusion derived from complex rearrangements, numerous single nucleotide variations or mutations, tremendous heterogeneity, and continuously punctuated evolution. Genome-wide CNAs, PTEN loss, MYC gain in primary tumors, and TP53 loss/mutation and AR amplification/mutation in advanced metastatic PCa have consistently been associated with worse cancer prognosis. With this recently gained knowledge, it is now an opportune time to develop DNA-based tests that provide more accurate patient stratification for prediction of clinical outcome, which will ultimately lead to more personalized cancer care than is possible at present.
Extending the traveling range with a cascade electrostatic comb-drive actuator

Electrostatic comb-drive actuators have been developed and employed for many applications. However, side stability (side pull-in) limits the actuator stroke constraining its applications. Hence, extending the stable traveling range is an important issue for designing electrostatic comb-drive actuators. This study presents a novel cascade electrostatic comb-drive actuator. Instead of shifting the spring constant of the suspended springs, the proposed actuator extends the stable traveling range using a multi-stage cascade configuration. To demonstrate the performance of the cascade configuration, simulation using the finite element method is utilized to model the proposed cascade actuator. To implement the cascade electrostatic comb-drive actuator, the Taiwan Semiconductor Manufacturing Company (TSMC) 0.35 μm two-polysilicon and four-metal layer (2p4m) CMOS processes and post-CMOS micromachining steps are employed to fabricate the device. Experimental results demonstrate that the proposed design extends the stable traveling range to 200% as compared with that of a comb-drive actuator without this cascade configuration.
Optimal On The Fly Index Selection in Polynomial Time

The index selection problem (ISP) is an important problem for accelerating the execution of relational queries, and it has received a lot of attention as a combinatorial knapsack problem in the past. Various solutions to this very hard problem have been provided. In contrast to existing literature, we change the underlying assumptions of the problem definition: we adapt the problem for systems that store relations in memory, and use complex specification languages, e.g., Datalog. In our framework, we decompose complex queries into primitive searches that select tuples in a relation for which an equality predicate holds. A primitive search can be accelerated by an index exhibiting a worst-case run-time complexity of log-linear time in the size of the output result of the primitive search. However, the overheads associated with maintaining indexes are very costly in terms of memory and computing time. In this work, we present an optimal polynomial-time algorithm that finds the minimal set of indexes of a relation for a given set of primitive searches. An index may cover more than one primitive search due to the algebraic properties of the search predicate, which is a conjunction of equalities over the attributes of a relation. The index search space exhibits a exponential complexity in the number of attributes in a relation, and, hence brute-force algorithms searching for solutions in the index domain are infeasible. As a scaffolding for designing a polynomial-time algorithm, we build a partial order on search operations and use a constructive version of Dilworth's theorem. We show a strong relationship between chains of primitive searches (forming a partial order) and indexes. We demonstrate the effectiveness and efficiency of our algorithm for an in-memory Datalog compiler that is able to process relations with billions of entries in memory.

Secondary failure of oral hypoglycaemic agents in lean patients with type 2 diabetes mellitus: insulin sensitivity, insulin response to different stimuli, and the role of cyclic-AMP.

The aim of this study was to evaluate the insulin (IRI) response to different stimuli and insulin sensitivity in Type 2 diabetic patients responsive to oral hypoglycaemic agents (OHA) and in Type 2 diabetic patients with secondary failure of OHA (SF), all patients being of normal body weight (relative body weight less than 120%), and the possible role of cyclic AMP in the reduced IRI release. SF patients, without islet cell antibodies (ICA), with hyperglycaemia lasting more than 3 months, underwent tests with i.v. tolbutamide (n = 21), i.v. glucose (n = 14), i.v. glucagon (n = 19), i.v. arginine infusion (n = 18); the arginine infusion was repeated in 12 patients during administration of aminophylline, an inhibitor of phosphodiesterase. The same tests were performed in groups of 8 to 15 OHA patients and in groups of 6 to 17 healthy subjects. During all the tests, blood glucose levels were higher in SF patients, than in OHA patients and in healthy subjects. Both SF patients and OHA patients had no IRI response to glucose; SF patients, in contrast to OHA patients, had a reduced IRI response to tolbutamide and to glucagon. The IRI response to arginine was not different in OHA, in SF patients and in healthy controls, but was significantly enhanced by aminophylline only in healthy controls. Insulin infusions (1.66 mU/Kg/min for 90 min) were performed in OHA patients and in SF patients at blood glucose levels of 150 and of 250 mg/dl: during the last 60 min, the amount of glucose metabolized (M), and the insulin sensitivity (M/I) index were greater in OHA than in SF patients.

Diversity Management in Denmark: Evolutions from 2002 to 2009

This chapter explores how the management practice of diversity management evolved after being imported from the United States to Denmark, where it was translated into a specific organizational context in 2002. With a focus on field level variables, we examine whether a subsequent translation that was undertaken within another Danish organization in 2009 imitated the initial Danish translation, reverted to the original American meaning, or translated the practice anew to fit the contemporary Danish context. Our findings show support for the first and the last outcomes. The second translation reproduced the same dominant institutional logic and an attachment to the same organizational practice, namely corporate social responsibility. At the same time, changes in Danish political priorities from 2002 to 2009 provoked a new adaptation of diversity management, which testifies to the dynamic relationship between the field and the translated management practice.
[What causes the decrease in empathy among medical students during their university training?]

Zusammenfassung Fragestellung: Hauptziel der Studie war es, herauszufinden, ob es zu einer Zunahme oder Abnahme von Empathie bei Medizinstudierenden im Laufe des Studiums kommt. Methode: Um dies zu eruieren, wurden die Theorie des geplanten Verhaltens (TPB) von Ajzen (1991) herangezogen und die generalisierte Intention der Studierenden, Empathie zu zeigen und die drei TPB-Komponenten Verhaltensuberzeugung, Normuberzeugung und Kontrolluberzeugung eruiert. Zunachst wurde ein Pilot-Fragebogen mit offenem Antwortformat zur Erhebung indirekter Uberzeugungen an 50 Studierende ausgegeben. Basierend auf diesen Antworten wurde ein quantitativer Fragebogen entwickelt und 131 Studierende des zweiten und vierten Studienjahres fullten diesen aus. Ergebnisse: Die multiple Regressionsanalyse zeigte, dass sich die generalisierte Intention zur Empathie verlasslich durch die drei TPB-Komponenten voraussagen lasst. Den starksten Pradiktor stellte die Normuberzeugung dar. Zudem konnte eine signifikante Abnahme der generalisi.
WeTab: hacia la construcción de entornos multi-superficie para juegos de sobremesa basados en tabletas

Resumen. La reunion de varios usuarios alrededor de una mesa para realizar actividades de juego colaborativas ha demostrado ser beneficiosa en terminos de productividad, calidad de los resultados y fomento del aprendizaje entre otros. Sin embargo, el alto coste de las superficies interactivas tradicionales ha limitado su implantacion de forma generalizada. El gran crecimiento en ventas durante los ultimos anos de superficies interactivas de menor tamano y coste como son las tabletas y los telefonos inteligentes permite considerar a estos dispositivos como sucesores de las superficies tradicionales de gran formato. En este articulo discutiremos los diferentes asuntos que hay que tener en cuenta cuando se adopta a las tabletas como herramientas para construir espacios de trabajo colaborativos de sobremesa, y describiremos la implementacion tecnica de WeTab, un prototipo multi-superficie preliminar de bajo coste.
Space-variant spatio-temporal filtering of video for gaze visualization and perceptual learning

We introduce an algorithm for space-variant filtering of video based on a spatio-temporal Laplacian pyramid and use this algorithm to render videos in order to visualize prerecorded eye movements. Spatio-temporal contrast and colour saturation are reduced as a function of distance to the nearest gaze point of regard, i.e. non-fixated, distracting regions are filtered out, whereas fixated image regions remain unchanged. Results of an experiment in which the eye movements of an expert on instructional videos are visualized with this algorithm, so that the gaze of novices is guided to relevant image locations, show that this visualization technique facilitates the novices' perceptual learning.
Memoryless Rules for Achlioptas Processes

In an Achlioptas process two random pairs of $\{1,\dots,n\}$ arrive in each round and the player has to choose one of them. We study the very restrictive version where a player's decisions cannot depend on the previous history and only one vertex from the two random edges is revealed. We prove that the player can create a giant component in $(2\sqrt{5}-4+o(1))n=(0.4721\ldots+o(1))n$ rounds and that this is the best possible. On the other hand, if the player wants to delay the appearance of a giant, then the optimal bound is $(1/2+o(1))n$, the same as in the Erdos-Renyi model.
Boosting for Regression Using Regression Error Characteristic Curves

Boosting is one of the most popular methods for constructing ensembles. The objective of this work is to present a boosting algorithm for regression based on the Regressor-Boosting algorithm, in which we propose the use of REC curves in order to select a good threshold value, so that only residuals greater than that value are considered as errors. The algorithm was empirically evaluated and its results were analyzed also by means of REC curves.
TEXEMS: Texture Exemplars for Defect Detection on Random Textured Surfaces

We present an approach to detecting and localizing defects in random color textures which requires only a few defect free samples for unsupervised training. It is assumed that each image is generated by a superposition of various-size image patches with added variations at each pixel position. These image patches and their corresponding variances are referred to here as textural exemplars or texems. Mixture models are applied to obtain the texems using multiscale analysis to reduce the computational costs. Novelty detection on color texture surfaces is performed by examining the same-source similarity based on the data likelihood in multiscale, followed by logical processes to combine the defect candidates to localize defects. The proposed method is compared against a Gabor filter bank-based novelty detection method. Also, we compare different texem generalization schemes for defect detection in terms of accuracy and efficiency.
