Closed-Loop di/dt and dv/dt IGBT Gate Driver

This paper proposes a new concept for attaining a defined switching behavior of insulated-gate bipolar transistors (IGBTs) at inductive load (hard) switching, which is a key prerequisite for optimizing the switching behavior in terms of switching losses and electromagnetic interference (EMI). First, state-of-theart gate driver concepts that enable a control of the IGBT’s switching transients are reviewed. Thereafter, a highly dynamic closedloop IGBT gate driver using simple passive diC /dt and dvCE /dt feedbacks and employing a single analog PI-controller is proposed. Contrary to conventional passive gate drivers, this concept enables an individual control of the current and voltage slopes largely independent of the specific parameters or nonlinearities of the IGBT. Accordingly, a means for optimizing the tradeoff between switching losses, switching delay times, reverse recovery current of the freewheeling diode, turn-off overvoltage, and EMI is gained. The operating principle of the new gate driver is described and based on derived control oriented models of the IGBT, a stability analysis of the closed-loop control is carried out for different IGBT modules. Finally, the proposed concept is experimentally verified for different IGBT modules and compared to a conventional resistive gate driver.
Easy and cost-effective cuneiform digitizing

Modern researchers in the field of ancient Mesopotamian studies read th ir primary sources, cuneiform tablets, either manually, by moving lights around the tablet to maximize readability, or b y studying photographs (or drawn copies) when the actual tablet is not at hand. Although the latter method only h lds partial information, and is therefore less desirable, it is often the only available resource due to the inac cessibility of tablet collections. Recently, several digitizing projects have been proposed to provide acc urate 2D+ and 3D models of these tablets for digital preservation. However, these methods require manual intera c ion or are not available to many research groups due to their cost. Furthermore, the digitizing device should be quick ly deployable on-site, have an easy calibration procedure and should not have any moving parts which could be problematic in difficult circumstances. We therefore present a new fully automated cuneiform tablet digitizing solution th at is relatively inexpensive and easily field-deployable. The solution consists of a small, light-weight dome o f light sources and a digital camera. 2D+ representations of the tablets are created by use of photometric stere o. Th obtained information allows for photorealistic virtual re-lighting and non-photorealistic rendering of the tab lets in real-time through the use of programmable graphics hardware.
Data fusion of multi-source imagery based on linear features registration

Image fusion is the process of combining images captured by different sensors under different conditions. These images usually have different geometric and radiometric properties. The enormous increase in the volume of remotely sensed data has created the need for robust data processing techniques that can fuse data observed by different acquisition systems. This need is motivated by the fact that collected data by these sensors are complementary in nature. Therefore, simultaneous utilization of the collected data would guarantee a full understanding of the object/phenomenon under consideration. In this regard, a data-fusion procedure can be defined as being concerned with the problem of how to combine data and/or information from multiple sensors in order to achieve improved accuracies and better inference about the environment than could be attained through the use of a single sensor. Fusion of multi-source imagery captured under different conditions is a challenging problem. The difficulty is attributed to the varying radiometric and geometric resolutions of the acquired imagery. Image registration is considered as one of the most critical requirement for accurate data fusion. The most appropriate primitives, transformation function and similarity measure have been incorporated in a matching strategy to solve the registration problem. Experimental results using real data proved the feasibility and the robustness of the suggested method.
Korpuspragmatische Analysen alpinistischer Literatur

A view on linguistic data in the sense of corpus pragmatics leads to new insights in the domains of sociolinguistics, discourse linguistics and cultural studies. In corpus pragmatics, recurrent patterns of language use are interpreted as a result of social actions. Using modern corpus linguistic methods, these recurrent patterns of language use can be extracted in a data driven way from linguistic data. In our paper we show this techniques in the context of a corpus of alpine literature: The yearbooks of the Swiss Alpine Club (SAC). The study shows how "talking about mountains" has changed from 1864 to today.
Missing the Meaning? A Cognitive Neuropsychological Study of Processing of Words by an Aphasic Patient

pituitary stalk in CT diagnosis of empty sella. A section on interventional neuroradiology is really too short and sketchy to be useful, and the brief account of spinal angiography contains an unhelpful classification of angiomas which omits the common dural AV fistula. Also, there are a few rather careless errors: for example, hypoplasia of the basisphenoid, with shortening of the clivus and small condyles, is described under the heading "Basisphenoid Hyperplasia"; and under the Davidoff Dyke syndrome there is a sentence discussing thinning of the calvarium by a cystic mass which presumably relates to an immediately previous paragraph dealing with porencephaly. The text is extensively illustrated, mainly with very adequate images, but some of the radiographs have not reproduced well and occasionally the relevant features can hardly be detected: for example, calcification in tuberous sclerosis (Fig 2.26) and the arcuate foramen (Fig 9.3). There are occasional inaccuracies in captions, such as the tentorial artery being described as the posterior communicating artery (Fig 5.25). The concept and lay-out of the book are fine, but it really needs some revision before it could be recommended unreservedly as a good introduction to neuroimaging.

The effects of current dietary trends and consumption patterns on health: evidence from the UK

This paper is an overview of the effects that current dietary trends and consumption patterns have had upon the health of the vast majority of the world's population, with a focus on the UK. The increasing prevalence of obesity and other diet-related diseases is a global epidemic which is predicted to result in unsustainable healthcare costs with impossible demands on surgical and drug treatments. The impact of poor nutritional choices and dietary trends is even more apparent in the UK, where high rates of cardiovascular diseases and obesity pose a serious alert for its citizen's health and well-being. By reporting chronic diseases as well as obesity rates together with the costs to both the economy and society, it highlights the need for intervention.
Managing Business Processes in the Age of Digital Transformation: A Literature Review

 Abstract— Today, digital transformation is one of the leading topics that occupy the attention of scientific circles and business experts. Organizational success is most often reflected through the successful managing of business processes. Given the growing market for digital innovations and its ever-increasing impact on business, organizations need to be prepared for organizational changes that come with the digital era. In order to maintain their competitive advantage in the global market, organizations must adapt their processes to new digitalization conditions. The main goal of this study is to point out the link between the digital transformation and the business process management concept. Therefore, in order to contribute to the scientific field that explores the potential relation between business process management concept and digital transformation, a literature review has been conducted. Papers have been searched within the Business Process Management Journal by keywords related to the term digital transformation. Selected papers have been analyzed according to the topic, type of publication, year of publication, keywords, etc. The results reveal a growing number of papers published on the topic of digital transformation to the Business Process Management Journal, but the lack of case studies. This paper contributes to the extension of academic literature in this important, yet insufficiently researched, scientific field that creates the bond between two strong concepts of digital transformation and business process management.
CUSTOMER RELATIONSHIP MANAGEMENT IN HEALTH ORGANIZATION

CRM is a system that the customer-patient puts at the heart of the business process, and the deployment of the best CRM practices is the key to providing loyalty from customers as an integral part of a successful business. With this system, it is possible to study the behavior of the customer, thus providing the right direction for the best service of the customer and improving the relations and connections with them. CRM is the integration of sales, marketing, services and support strategy, processes, people and technologies to maximize customer benefits, values, relationships, and customer retention and their loyalty. These data are the basis for preparing information for marketing managers who need to help them in the decision-making process. Customer behavior is put in the focus of modern companies so that the CRM system is a synthesis of more functionalities such as sales, management, marketing and communication with customers as the main feature. These are methods for collecting and accumulating data for users and their behavior, preferences, inclinations and requirements Marketing decision support systems are usually part of CRM systems, which are a broad concept covering marketing activities, sales and overall communication, and customer relationships. The data collected is adapted to the marketing activities and the needs of marketing managers. Health CRM is a Customer Relationship Management System, designed specifically for use by healthcare organizations. Health CRM involves multiple sources of data (demographic data for consumers and patients, psychography, social, behavioral, clinical, financial, websites, call center, service check, etc.) to provide a comprehensive overview of the habits and activities of patient. The primary goal of the CRM healthcare system is to increase the quality of healthcare and the lives of patients to recruit new ones, and to retain existing patients.
The impact of unreasonable expectations of the financial statements users on the audit expectations gap in Palestine

This paper aims to determine the structure of unreasonable expectation gap in Palestine by evaluating the perceptions of financial statements users’ in Palestine about auditor responsibilities, goals and usefulness of auditing, and the lack of knowledge about auditing profession in general. To achieve this goal questionnaire was established including items were designated to answer the hypotheses of the study. (300) questionnaires were distributed for the internal and external users of financial statements. (232) questionnaires were reached. This number represents (77.33%) of the distributed questionnaires. Descriptive, T-test, and Non-Parametric test were used Specifically Kruskal –Wallis. The results of study found evidence of a wide unreasonable audit expectation gap in Palestine. In the areas of auditor responsibility, audit benefits and goals, and some issues that related to audit profession in general, furthermore, the study found that there are significant statistical differences in the average of correspondent opinions about the structure of unreasonable expectation gap.
Content-based image retrieval using shape features indexed by compact R-trees

Accuracy and efficiency are two major issues in designing Content-Based Image Retrieval (CBIR) systems. Most of CBIR systems were dedicated to visual feature extraction because it has been shown that significant visual informations extracted from images can achieve similarity retrievals with high performance of effectiveness. However, in their studies, exhaustive searches were usually performed to generate a moderate number of plausible retrievals in response to a user's query. As a result, retrieval efficiency becomes a bottleneck when the matching process is progressed over a large volume of image
Preliminary experience in oncology of positron emission tomography with a dual headed gamma camera

Abstract Purpose: To evaluate positron emission tomography (PET) performed using a modified dual-headed gamma camera for the imaging of malignancy. Methods: Using a modified dual-headed gamma camera (Picker 2000XP) we performed 18-FDG PET scans on 19 patients with non-small cell lung cancer (NSCLC) and 27 with lymphoma. Results were compared to computed tomography (CT) findings and pathology, when available. Results: All untreated primary NSCLC were identified. Response to chemotherapy was demonstrated in one case. For staging mediastinal lymph nodes in untreated NSCLC, gamma camera PET was superior to CT, with sensitivity 75%, specificity 89%, accuracy 85%, positive predictive value (PPV) 75% and negative predictive value (NPV) 89%. All adrenal masses in NSCLC were correctly identified as benign, but in one case bone metastases were missed. In lymphoma, gamma camera PET had sensitivity 82%, specificity 97%, accuracy 96%, PPV 74% and NPV 98% but it missed lesions smaller than 10mm in the thorax and neck, and Conclusions: These early results suggest that functional tumour imaging with 18-FDG PET is a useful technique in the management of cancer. Modified dual-headed gamma cameras can be used to acquire 18-FDG PET images in oncology patients.
Motion analysis using stochastic optimisation and posture disambiguation

Studies in biomechanics, neuroethology or motor physiology often rely on kinematic analyses of the investigated movement sequence. Commercially available motion capture systems typically depend on costly hardware solutions, involving high frame rates and several camera views. Here, we introduce a low-cost motion capture algorithm that uses a manipulable kinematic model of the tracked limb or animal and stochastically optimises the model posture to match the recorded camera views. 3D movements may be analysed from a single camera view. A disambiguation method based on Markov chain analysis then determines the most likely movement sequence. Additionally to the desired joint angle time courses, the system returns local accuracy measures for each joint angle, that can be used to constrain a smoothing spline method to remove noise efficiently while preserving fast joint angle fluctuations that are real.
Range estimation using angle-only target tracking with particle filters

We consider the recursive state estimation of a maneuverable aircraft using an airborne passive IR-sensor. The main issue addressed in the paper is the range- and velocity estimation using angle-only measurements. In contrast to standard target tracking literature we do not rely on linearized motion models and measurement relations, or on any Gaussian assumptions. Instead, we apply optimal recursive Bayesian filters directly to the nonlinear target model. We present novel sequential simulation based algorithms developed explicitly for the angle-only target tracking problem. These Monte Carlo filters approximate optimal inference by simulating a large number of tracks, or particles. In a simulation study our particle filter approach is compared to a range parameterized extended Kalman filter (RPEKF). Tracking is performed in both Cartesian and modified spherical coordinates (MSC).

Is cooperation cost reducing? An analysis of public–public partnerships and inter-municipal cooperation in Brazilian local government

ABSTRACT In local government systems worldwide, financial pressures have obliged local authorities to focus on cost-efficient methods for providing local services, including inter-municipal agreements and public–public partnerships. However, in comparison with municipal mergers, privatisation and other approaches to the problem, the cost impact of the cooperative provision has not yet been thoroughly examined empirically. Moreover, available empirical research has largely concentrated on waste disposal in developed countries. The present paper seeks to contribute to the empirical literature on inter-municipal agreements and public–public partnerships by comparing their impact on costs with ‘stand-alone’ provision in a range of non-waste local services. In contrast to the bulk of existing studies, our analysis takes place in a developing country context by examining Brazilian local government over the period 2013/15. We found that – on the whole – cooperative provision is less expensive than the ‘stand-alone’ provision for the services studied. Our results can be explained by the size and composition of the population, together with the politics for cooperation.
Courbes et surfaces pour la CFAO

Jusqu’a une date recente, les dessins de pieces de mecanique ne donnaient pas une description complete de l’objet qu’ils etaient censes representer. Les surfaces requerant quelque precision etaient definies par des dimensions assorties de tolerances ; leur geometrie etait fondee sur l’emploi de la droite et du cercle ; les depouilles et les raccordements etaient determines de facon plus ou moins vague, et parfois implicite, et leur realisation etait laissee a l’initiative de professionnels hautement qualifies : modeleurs, fondeurs ou ajusteurs de matrices. Quant aux autres formes gauches, elles etaient representees par des traces de diverses sections, et reproduites ensuite par copie de modeles derivant des traces par une interpolation laissee aux soins d’operateurs tres experimentes. Afin d’utiliser la commande numerique pour diriger des aleseuses, des tours, des fraiseuses, des rectifieuses, des machines d’electroerosion ou de soudure, il devenait indispensable de disposer d’une definition complete et precise de toutes les surfaces a realiser. Cette question a donne lieu a beaucoup de travaux. On trouvera en references bibliographiques la liste des principaux ouvrages publies en francais ou en anglais ; la liste des articles parus dans les revues specialisees compterait plusieurs milliers de references.
Performance of urban microcellular communication systems with overlapping coverage

Microcellular structures are employed in order to maximize the spectrum efficiency of the radio system. Previous studies and measurements have examined a cell shape in urban areas with rectilinear streets in the form of a squared diamond with four tails that introduce overlapping coverage among the cells. The effect of this overlapping on the performance of the urban microcells is addressed. Stochastic analysis and simulation are used to quantify the effect of overlapping on the performance measures. The results demonstrate the improvement in the teletraffic performance measures and the resultant degradation in the signal-to-interference ratio, S/I.
Relação entre a dor lombar crônica não específica com a incapacidade, a postura estática e a flexibilidade

RESUMO Dentre as dores musculoesqueléticas crônicas, um dos sintomas mais comuns, com uma prevalência de 84% durante a vida, é a dor lombar. Apesar de sua elevada incidência, suas causas e fatores de risco são pouco conhecidos. O objetivo deste trabalho foi: (1) comparar a flexibilidade e as características da postura estática entre indivíduos com e sem dor lombar crônica não específica; e (2) verificar se existe relação entre a presença e intensidade da dor lombar crônica não específica com a incapacidade, a flexibilidade e as características da postura estática. Participaram do estudo 104 indivíduos adultos, com idade entre 18 e 60 anos. A amostra foi dividida em dois grupos: grupo com dor lombar crônica não específica (GCD; n=52) e grupo sem dor lombar (GSD; n=52). A coleta de dados consistiu em quatro etapas: (1) anamnese; (2) avaliação postural estática por fotogrametria, utilizando o protocolo do software Digital Imaged Postural Assessment (DIPA©); (3) testes especiais de flexibilidade corporal; e (4) aplicação do questionário Oswestry Disability Index (ODI). A intensidade da dor apresentou correlação significativa com o índice de incapacidade (r=0,42; p=0,00) e com o banco de Wells (r=-0,32; p=0,02). Não houve correlação entre a presença de dor e postura estática e flexibilidade, como também não houve diferença entre os grupos. Indivíduos com maior intensidade de dor lombar crônica não específica apresentaram maior incapacidade e menores resultados no teste do banco de Wells.
