Indirect Pulse-vector Control of Wound Rotor Induction Motor Drive in ANSYS Electromagnetics Suite

This paper deals with the problem of estimation of rotor angular position for the indirect pulse-vector control of wound rotor induction motor drive. The paper considers issues of thematic justification and expanding of the field of using sensorless motor drives. With a view to improve energy consumption readings during design and modernization of motor drives of massive mechanisms with moderate standards for accuracy of velocity control, requiring long-term velocity decrease during load reduction (according to technological process conditions), using the system of the pulse-vector control of wound rotor induction motor is suggested. The paper provides the solution for the problem of developing math models of this motor drive system both for the motor-mounted sensor, and for indirect angular position sensing. The models were developed in ANSYS Electromagnetics Suite using the finite element method for studying electromagnetic processes. Based on the models, the investigation of transition and steady states of a motor drive was carried out, process quality parameters were obtained, namely: max and root-mean-square currents, torques; velocity control errors caused by pulse operation mode. From that simulation, the result illustrates the effectiveness of the proposed approach.
Q A ] 2 6 A ug 2 01 5 A modular invariance property of multivariable trace functions for regular vertex operator algebras

We prove an SL2(Z)-invariance property of multivariable trace functions on modules for a regular VOA. Applying this result, we provide a proof of the inversion transformation formula for Siegel theta series. As another application, we show that if V is a simple regular VOA containing a simple regular subVOA U whose commutant U c is simple, regular, and satisfies (U c)c = U , then all simple U -modules appear in some simple V -module.
Genuine Concern for Environmental Sustainability : An Antidote to Organizational Simplicity and Failure

Despite the vast and varied research on individuals, organizations, industries, organizational populations and the broad environment surrounding organizations, the cumulated body of knowledge on the sustainability of organizational success still offers fascinating challenges to both research and practice. Aiming at contributing theoretical insights into the sustainable success of organizations, this paper builds on the notions of organizational archetypes of success and failure (Miller & Friesen, 1977; Fleck, 2009) and organizational simplicity (Miller, 1993), a process whereby successful organizations become simpler and more vulnerable to undergo selfdestructive processes. Building on the two approaches, this paper develops the argument that sustainable organizational success requires a sustainable environment for organizations to operate, and puts forward a set of propositions regarding sustainable organizational success. Theoretical development advances the notion that including the earth among the organization’s stakeholders helps to neutralize the organization’s propensity to trigger simplicity processes and develop a self-destructive propensity. As a result, environmental turbulence can be seen as more than opportunities for new business activities or threats to existing business; it embodies an important potential antidote to organizational simplicity, a process whereby organizational success turns into failure.
Acoustic Correlates of Stress in Tone Language : A Comparison between Indian and Chinese Languages

As tonal languages use pitch and stress to signal a difference in meaning between words (Avery 1977), the acoustic factors which contribute to this stress patterns in Indian tonal languages may differ from the stress patterns in Chinese tonal language. Hence the present study aimed at identifying the acoustic correlates of stress in the Mizo language and Mandarin language. 10 native Mizo speakers and 10 native Mandarin speakers participated in the study. Ten phrases were selected in each language. All the speakers were asked to say those phrases in stressed and unstressed conditions. Recorded phrases of both the languages were subjected to acoustical analysis and Tone Duration, Tone Height and Peak Amplitude was measured and S-ratios for the same parameters were calculated. The results indicated that tone duration was the major cue for stress in Mizo language and both tone duration and peak amplitude were the cues of stress in Mandarian language. The obtained data will foster our understanding of the behavior of stress in Indian tonal languages as well as Chinese tonal languages.

The influence of knee position on blood loss and range of motion following total knee arthroplasty : a meta-analysis

A consistent post-operative limb positioning regime could be an attractive, simple and cost-effective alternative to improve patient’s outcomes after total knee arthroplasty (TKA). The aim of this study was to perform a meta-analysis to determine the effect of postoperative knee position (flexion vs extension) on blood loss and range of motion (ROM) following TKA. A systematic search of all studies published through Dec 2015 was conducted using the MEDLINE, EMBASE, OVID, ScienceDirect and Cochrane CENTRAL databases. The relevant studies that examined whether post-operative limb positioning (flexion or extension) could effectively improve ROM restoration and reduce blood loss following TKA were identified. Demographic characteristics, blood loss and range of motion were manually extracted from all of the selected studies. Meta-analysis was conducted with the help of REVMAN software. Nine randomized controlled trials are eventually satisfied the eligibility criteria. Meta-analysis showed that post-operative knee flexion protocols could effectively reduce blood loss (SMD = -0.32, 95% CI: -0.59--0.05) and improve ROM (WMD = 4.47, 95% CI: 2.53-6.41) after TKA. No significant publication bias was showed by funnel plot. Based on the studies undertaken to date, a post-operative knee flexion protocol should be implemented as an easy and inexpensive method of reducing blood loss and increasing ROM following TKA. Further studies are still needed to confirm the present results.
Speech / Music Change Point Detection using Subband Coding and SVM

The aim of audio change point detection is to check for differences in the distribution of adjacent windows and the transition of the types of audio. In this paper, Subband Coding (SBC) features are extracted which are used to characterize the audio data. Support Vector Machine (SVM) is used to detect change point of audio. The results achieved in our experiments illustrate the potential of this method in detecting the change point between speech and music changes in audio signals.

EMPLACEMNET AND RETRIEVAL CONCEPTS FOR GERMAN SF / HLW REPOSITORIES IN CLAYSTONE

Within the framework of the R&D project ANSICHT (Safety Assessment Methodology for a German High-level Waste Repository in Clay Formations), DBE TECHNOLOGY GmbH, BGR, and GRS developed an integrated methodological approach on how to demonstrate the safety of a HLW repository in claystone in Germany. One challenging aspect of this approach was the design of a repository concept for the two known potential host rock formations; huge Jurassic claystone layers in the northern part of Germany and thinner but well-known claystone layers in the South, also known as Opalinus Clay. For the northern reference geology, the disposal of unshielded canisters in vertical boreholes was designed as preferred emplacement concept. For the Opalinus Clay, drift disposal of shielded POLLUX ® casks was identified as the most suitable emplacement concept. In addition, the ERNESTA study (Development of Technical Concepts for the Retrieval of Waste Containers with Heat-generating Waste and Spent Fuel from Repositories in Salt and Clay Formations) was initiated to investigate in parallel how to fulfil the requirement for retrievability in both concepts. In Germany, retrievability is a design criterion and requirement for licensing stipulated by the “Safety Requirements Governing the Final Disposal of Heat-Generating Radioactive Waste”, established in 2010.
MICROFLUIDIC SYSTEM FOR THE STUDY OF MECHANICAL AND BIOCHEMICAL RESPONSE OF ENDOTHELIAL CELLS TO FLOW-INDUCED MECHANICAL STIMULI

A microfluidic system for the in vitro study of the mechanical and biochemical response of endothelial cells (ECs) to the flow-induced mechanical stimuli is presented. A tapered microfludic channel is used to impose an homogeneous flowinduced shear stress gradient on an EC layer. The topography and shear stress distribution over individual cells is determined from flow velocity measurement performed by micro-Particle-Image-Velocimetry (µPIV). The µPIV measurement are performed simultaneously with gene expression measurements. Results are shown to prove the functioning of the system.
Fast and effective dynamic mesh completion

We introduce a novel approach to support fast and efficient completion of arbitrary animation sequences, ideally suited for real-time scenarios, such as immersive tele-presence systems and gaming. In most of these applications, the reconstruction of 3D animations is based on dynamic meshes which are highly incomplete, stressing the need of completion approaches with low computational requirements. In this paper, we present a new online approach for fast and effective completion of 3D animated models that estimates the position of the unknown vertices of the current frame by exploiting the connectivity information and the current motion vectors of the known vertices. Extensive evaluation studies carried out using a collection of different incomplete animated models, verify that the proposed technique achieves plausible reconstruction output despite the constraints posed by arbitrarily complex and motion scenarios.
Optimization of the conditions for rice bran phytate degradation by their own phytases

The rice bran by-product of rice during milling process chemically contains moisture, ash, crude protein (12%), crude fat (15%), crude fiber 7%, crude carbohydrate (31.1%), and energy. It contains high phytate and dietary fiber contents. The cereal whole paddy after milling produces 8% of rice bran. Rice bran amino acid profile has been normally suggested to be superior to cereal grain proteins. Existing phytase within the rice bran generally improves phytate phosphorus utilizations. The present study has been conducted to find the effect of phytase activity of rice bran against five different temperatures and also the effect of phytase activity of rice bran against five different temperatures at optimum pH 5.5. The results showed that as the concentration of rice bran increases from 0 to 20%, the phytase activity also increased. The optimum phytase activity was found at 10% concentration of rice bran at 37°C. Moreover, an increase in phytase activity at the same concentration of rice bran was observed while adjusting the pH at pH 5.5. The four concentrations of rice bran showed gradual increase in activity at 50°C which was directly proportional to the concentrations of rice bran and comparatively better while adjusting the pH at pH 5.5. Around two-fold increase in activity was observed at room temperature and 50°C when the concentration of rice bran was increased from 5 to 20% with and without pH 5.5 adjustments.
Kernel Regularized Nonlinear Dictionary Learning for Sparse Coding

For most sparse coding methods, data samples are first encoded as hand-crafted features, followed by another separate learning step that generates dictionary and sparse codes. However, such feature representations may not be optimally compatible with the learning process, thus producing suboptimal results. In this paper, we propose a new architecture for nonlinear dictionary learning with sparse coding, in which samples are mapped into sparse codes via carefully designed stacked auto-encoder (SAE) networks. We jointly learn a low-dimensional embedding of the data samples by means of an SAE and a dictionary in the low-dimensional space. Further, to leverage the prior knowledge, we develop a kernel regularized nonlinear dictionary learning method, which effectively incorporates the knowledge provided by the hand-crafted kernel. An iterative algorithm is developed to jointly search the solutions of the associated optimization problem and extensive experimental validations are performed to show that the proposed kernel regularized dictionary learning method achieves satisfactory performance.

Optimal Production and Sales Plans for a New Product in the Presence of Scarcity Effects

We develop integrated production and sales planning model for new product under supply constraint. We consider product scarcity situations and its consequences namely hype and retarding effects. We identify situations where strategic sales delay and myopic sales policies can be optimal. Under retarding effect, we show that the length of build-up period depends upon magnitude of retarding effect.
Comparing MongoDB to SQL Server, Replicated

htmlabstractParker et al [1] studied the performance difference between MongoDB and Microsoft SQL Server on basis of a number of insert, update and select scenarios. As the result of their study, they conclude that MongoDB has got a better performance when it comes to insert, update and simple queries. However, Microsoft SQL Server performs better when updating and querying the non-key fields (attributes) as well as for aggregate queries. In this Master thesis we replicate the mentioned study in order to validate its results. Moreover, we extend the study with more data in order to monitor how both databases perform when the data grows. Although there are differences between the exact values in the results of both studies, we also conclude that MongoDB performs better in case of insert, update and key field related queries. However, when non-key field related queries are utilized we see that SQL Server has got a better performance. In case of aggregate queries we also see the similar results as in [1] i.e. SQL Server performs better than MongoDB. However, we see that the new aggregate framework of MongoDB provides a significant improvement with respect to the method used in [1] which results in a slightly better performance than SQL Server. Furthermore, we show how different implementation of the experiment can significantly affect the results. The results of this study will help us to answer the question whether or not to choose a NoSQL database in case of a modest-sized database with structured data from the performance point of view.
Bandit-Based Genetic Programming with Application to Reinforcement Learning

When looking for relevant mutations of a learning program, a main trouble is that evaluating a mutation is noisy; we can have a precise estimate of a mutation, if we test it many times, but this is quite expensive; or we can have a rough estimate, which is much faster. This is a load balancing problem: on which mutations should we spend more effort ? Bandit algorithms have been used for this load balancing: they choose the com-putational effort spent on various possible mutations, depending on the current estimate of the quality of a mutation and on the precision of this estimate. How-ever, in many cases, we want to validate some possible mutations; when should we stop the bandit mutation, and analyze new mutations ? Racing algorithms are aimed at combining the load balancing and the statistical validation; we here mathematically analyze and experiment racing algorithms in the context of mu-tations of programs, i.e. genetic programming. As an application, we consider Monte-Carlo Tree Search. Monte-Carlo Tree Search is a recent very successful algorithm for reinforcement learning, success-fully applied in games and Markov decision Processes. We consider the valida-tion of randomly generated patterns in a Monte-Carlo Tree Search program. Our bandit-based genetic programming (BGP) algorithm, with proved mathematical properties, outperformed a highly optimized handcrafted module of a well-known computer-Go program with several world records in the game of Go.
Economic efficiency of organic and peri-urban fadama agriculture in southwestern , Nigeria : A stochastic frontier approach

As part of the major effort to improving the food situation and livelihood of the Nigerians particularly the city dwellers as more than half of the poor people in developing countries including Nigeria live in urban areas (UNDP, 2003). A study was conducted on the economic efficiency of small scale organic and peri-urban fadama farmers in Nigeria. Data were collected from 480 organic and peri-urban fadama farmers selected using multi-stage sampling technique and analysed using budgetary technique, stochastic frontier production and cost function models. The result of the budgetary technique shows that the average revenue and profit generated by peri-urban fadama farmers in the study area were N105,897.86 and N39,342.24 respectively. The return to scale (RTS) for the production function revealed that farmers operated in the irrational zone (stage 1) of the production surface having RTS of 1.135. The mean technical, allocative and economic efficiency of 88.3, 72.1 and 61.4 percent respectively were obtained from the data analysis, indicating that the sampled farmers were relatively technically efficient in their resource use. The results of the analysis indicate that presence of technical and allocative efficiencies had effects in peri-urban fadama crop production as depicted by the significant gamma coefficient of the model, generalized likelihood ratio test, predicted technical and allocative efficiencies within the farmers.
DEVELOPMENT OF AN IMPROVED RESPONSE ULTRA-WIDEBAND ANTENNA BASED ON CONDUCTIVE ADHESIVE OF CARBON COMPOSITE

Ultra-wideband (UWB) antennas have advantages such as high data rates, improved multipath resistance and low power consumption. In this work, UWB patch antennas based on electrically conductive adhesive were manufactured with a simple technique and evaluated in the laboratory. Results showed that the thickness of the samples ranged from 207 to 261 μm. The bandwidth optimization obtained was 200% compared to a traditional copper-layer antenna. UWB antennas showed an average bandwidth of 8.558 GHz in the region 609 MHz to 9.105 GHz. The antennas covered the whole of UHF band, L band, S band, C band and part of X band. Finally, the proposed technique allows reducing the size of patch by 70% for low frequencies of operation, while achieving a similar performance.
O ct 2 00 3 IFT-UAM / CSIC-03-41 HU-EP-03 / 73 On Sp ( 0 ) factors and orientifolds

We discuss the geometric engineering of SO/Sp gauge theories with symmetric or antisymmetric tensor matter and show that the ‘mysterious’ rank zero gauge group factors observed by a few authors can be traced back to the effects of an orientifold which survives the geometric transition. By mapping the Konishi constraints of such models to those of the U(N) theory with adjoint matter, we show that the required shifts in the ranks of the unbroken gauge group components is due to the flux contribution of the orientifold after the transition.
Query Expansion for Multi-script Information Retrieval

For many languages that use non-Roman based indigenous scripts (e.g., Arabic, Greek and Indic languages) one can often find a large amount of user generated transliterated content on the Web in the Roman script. Such content creates a monolingual or multi-lingual space with more than one script which we refer to as the Multi-Script space. IR in the multi-script space is challenging because queries written in either the native or the Roman script need to be matched to the documents written in both the scripts. Moreover, transliterated content features extensive spelling variations. In this paper, for the first time, we formally introduce the concept of Multi-Script IR, and through analysis of the query logs of Bing search engine, estimate the prevalence and thereby establish the importance of this problem. We also give a principled solution to handle the multi-script term matching and spelling variation where the terms across the scripts are modelled jointly in a deep-learning architecture and can be compared in a low-dimensional abstract space. We present an extensive empirical analysis of the proposed method along with the evaluation results in an ad-hoc retrieval setting of multi-script IR where the proposed method achieves significantly better results (12% increase in MRR and 29% increase in MAP) compared to other state-of-theart baselines.
Between care and control Interaction between refugees and caseworkers within the Norwegian refugee integration programme Sussex Migration Working

This dissertation is a case study from Norway focusing on social interaction between refugees and caseworkers within the framework of a recent integration programme, the so-called Introductory Programme. The main objective of my analysis is to illustrate how the relation between the refugees and caseworkers is influenced by the policy, and to describe some of the challenges they face. My central argument is that both the refugees and the caseworkers have adopted more complex tasks and roles under the programme, and I discuss what impacts this appears to have on the relation between the two parties.
