Nonlinear Optimal DTC Design and Stability Analysis for Interior Permanent Magnet Synchronous Motor Drives

This paper presents a nonlinear optimal direct torque control (DTC) scheme of interior permanent magnet synchronous motors (IPMSMs) based on an offline approximation approach for electric vehicle (EV) applications. First, the DTC problem is reformulated in the stationary reference frame in order to avoid estimating the stator flux angle, which the previous DTC schemes in the rotating stator reference frame require. Thus, the proposed DTC method eliminates the Park's transformation, and consequently, it reduces the computational efforts. Particularly, since the estimated stator flux angle is not accurate in low speed range, the proposed method that does not need this information can significantly improve the control performance. Moreover, a nonlinear optimal DTC algorithm is proposed to deal with the nonlinearity of the IPMSM drive system. In this paper, a simple offline θ-D approximation technique is utilized to appropriately determine the controller gains. Via an IPMSM test bed with a TI TMS320F28335 DSP, the experimental results demonstrate the feasibility of the proposed DTC method by accomplishing better control performances (e.g., more stable in low speed region, much smaller speed and torque ripples, and faster dynamic responses) compared to the conventional proportional-integral DTC scheme under various scenarios with the existence of parameter uncertainties.
Conformal flattening maps for the visualization of vessels

In this note, we employ a conformal mapping technique for flattening branching tubular structures for visualization of MRA and CT volumetric vessel imagery. This may be used for the study of possible vessel pathology (cerebral embolism, cerebral thrombosis, or lung nodules near vessels). Our method is based on a discretization of the Laplace-Beltrami operator to flatten a surface onto a planar polygonal region in an angle-preserving manner.
Guided tissue regeneration associated with bovine-derived anorganic bone in mandibular class II furcation defects. 6-month results at re-entry.

BACKGROUND The use of graft materials with guided tissue regeneration (GTR) in Class II furcation defects is aimed at improving the outcome of the regenerative technique. In this regard, however, there are a limited number of studies discussing the results obtained when GTR and graft materials are used in the treatment of Class II furcation defects. Furthermore, most studies employ either allogeneic or autogenous materials. The present trial sought to determine whether the use of a bovine-derived anorganic bone (ABB) in conjunction with GTR influenced the outcome of mandibular Class II furcation treatment. METHODS This study included 14 patients who provided 15 pairs of similar periodontal defects. Each defect was randomly assigned to treatment with either a cellulose membrane in combination with bovine-derived anorganic bone (GTR+ABB) or membrane alone (GTR). Following basic therapy, baseline measurements were recorded including probing depth (PD), clinical attachment level (CAL), and gingival margin position (GMP). Hard tissue measurements were performed during surgery to determine alveolar crestal height (CEJ-AC), and vertical (VDD) and horizontal defect depth (HDD). Membranes remained in position for at least 4 weeks. After 6 months, all sites were re-entered and soft and hard tissue measurements were recorded. RESULTS Both surgical procedures resulted in statistically significant probing depth reduction and gain in clinical attachment levels, with no significant difference between groups. Gingival recession was more pronounced in the GTR+ABB group (0.87 +/- 0.83 mm), but not statistically different from the GTR group (0.46 +/- 1.19 mm). Vertical defect resolution was significant in both groups (GTR: 1.60 +/- 1.50 mm; GTR+ABB: 1.80 +/- 2.11 mm), without differences between groups. Only horizontal furcation resolution (GTR: 2.47 +/- 0.99 mm; GTR+ABB: 3.27 +/- 1.39 mm) was significantly different between groups (P <0.05). CONCLUSIONS The use of ABB with GTR techniques improved horizontal defect resolution in mandibular Class II furcation defects, but did not yield superior results regarding soft tissue changes when compared to sites treated with GTR alone. Evaluation of a larger sample could indicate differences and advantages between the evaluated approaches and confirm the real necessity of associating filling materials with GTR.
Some results on cyclic codes over the ring R2,m

Let Rk;m be the ring F2m(u1;u2; � � � ;uk)= ⟨ u 2;uiuj ujui ⟩ . In this paper, cyclic codes of arbitrary length n over the ring R2;m are completely characterized in terms of unique generators and a way for determination of these generators is investigated. A F2m -basis for these codes is also derived from this representation. Moreover, it is proven that there exists a one-to-one correspondence between cyclic codes of length 2n, n odd, over the ring Rk 1;m and cyclic codes of length n over the ring Rk;m. By determining the complete structure of cyclic codes of length 2 over R2;m, a mass formula for the number of these codes is given. Using this and the mentioned correspondence, the number of ideals of the rings R2;m and R3;m is determined. As a corollary, the number of cyclic codes of odd length n over the rings R2;m and R3;m is obtained.
The effects of new ways of work in the Netherlands : national data and a case study

In 2010 15.2% of the work force in the Netherlands works with a computer at another location than at the office or at the clients’ location. 27% of the Dutch working population is not satisfied about the possibility to work at home and 18% is not satisfied on the possibility to plan your own working time. The case control study affirms what has been reported as effects of new ways of work: the experienced productivity by communication and the representativeness of the office interior are improved and attention is needed for workers that need concentration space and need to personalize their work environment. In implementing new ways of work these issues need attention.
Smart Wireless Temperature Data Logger

The real time data logging of a process variable is mission critical in process dynamics. Process variables (like temperature, pressure, flow, level) vary with time in certain applications and this variation should be recorded so that a control action can take place at a defined set point. This paper proposes an 8-bit embedded controller interfaced with a temperature sensor through Analog to Digital convertor. This portable data logger is programmed to control and log the temperature variations. The temperature is displayed on a liquid crystal display (LCD) interfaced with the 8-bit embedded controller and is wirelessly transmitted to a PC communication port or a PDA communication port through Infrared/Bluetooth link.
Predictors of In-Hospital Mortality in Patients with Successful Primary Coronary Intervention for Acute ST-Elevation Myocardial Infarction Presenting as Cardiogenic Shock

Background: Predictors of hospital mortality in patients with successful primary coronary angioplasty for ST-elevation myocardial infarction (STEMI) presenting as cardiogenic shock (CS) remained less specified. Methods: From 1996 to 2007, we evaluated 64 patients (56 men, 65 14 years) with STEMI and CS receiving successful intervention defined as residual stenosis < 40% by balloon angioplasty or < 20% by stenting with a TIMI grade 2 or 3 flow in the infarct-related artery. Results: Among the 64 patients, 37 (58%) had anterior infarction, and 26 (41%) had inferior infarction. In-hospital death occurred to 21 (33%) patients with a mean hospital stay of 11 18 days. Hospital mortality was associated with several pre- and peri-procedural parameters including initial higher white blood cell (16,629 6492 vs. 13,093 5387 1/L) and serum creatinine (1.7 0.6 vs. 1.2 0.3 mg/dl) levels, anterior infarction (76 vs. 49%), less stenting (38 vs. 65%), and post-intervention TIMI grade 2 flow (57 vs. 14%) (all p < 0.05). After multivariate analysis, initial creatinine 1.4 mg/dl (odds ratio: 8.9; p = 0.011, 95% confidence interval: 1.7-47.7), and anterior infarction (odds ratio: 5.9;p = 0.038, 95% confidence interval: 1.1-31.3) were independent predictors of in-hospital death. Conclusion:Anterior infarction or early renal dysfunction remained critical to the one-third mortality of successful intervention for patients with STEMI and CS.
Generation of stella‐GFP transgenic mice: A novel tool to study germ cell development

The relationship between germ cells and pluripotent embryonic stem (ES) cells is of particular interest, together with approaches to generate primordial germ cell (PGCs) from ES cells. A critical requirement in these experiments is the ability to unambiguously detect PGCs with the use of, for example, reporter genes. The currently available transgenic reporters do not show exclusive expression in PGCs at their earliest developmental stages. Here we describe the use of germline‐restricted expression of stella, which is currently the best marker gene for PGCs. We generated two stella‐GFP reporters and show that both transgenes surpass other reporters in terms of timing and specificity of expression in PGCs. Additionally, we demonstrate the usefulness of stella‐GFP during the derivation of PGCs from ES cells. genesis 44:75–83, 2006. © 2006 Wiley‐Liss, Inc.
Consensus building for the development of guidelines for recommending mobility service dogs for people with motor impairments

BACKGROUND: According to recent research, mobility service dogs (MSD) improve grasping ability, autonomy in ADL, manual wheelchair propulsion, walking, transfers, psychosocial aspects, reintegration into normal life, and satisfaction with important occupations, and decrease pain in manual wheelchair users’ shoulders/wrists. However, it remains a challenge for rehabilitation professionals to recommend MSD for different profiles of neurological disorders. OBJECTIVE: Formulate guidelines to support the decision-making process of rehabilitation professionals recommending MSD. METHODS: Focus groups with MSD experts (7 therapists, 4 trainers, 3 managers, 5 users) responded to four research questions. They had to formulate and prioritize criteria to inform the recommendation of MSD for three clinical cases: A-tetraplegia with powered wheelchair, B-paraplegia with manual wheelchair, and C-ambulatory (incomplete SCI or neurodegenerative disease). RESULTS: For the decision-making process of recommending MSD, six main variables were identified: scientific evidence cited (they are different among clinical cases), added value of MSD compared to other assistive devices (dissimilar among clinical cases), prioritization of personal (7), environmental (8) and canine (6) characteristics, and possible negative consequences in MSD user’s life (stigmatization, resilience, care burden, authority or obedience). CONCLUSIONS: The results provide the basis for the development of clinical practice guidelines for occupational therapists and physiotherapists recommending MSD to individuals presenting various profiles of neurological disorders.
A Systematic Approach to Bi-Directionally Nonlinearly Coupled Systems Design for the Generation of Complex Dynamical Behaviours

In this paper, a procedure to design a class of coupled systems that exhibit complex behaviours is presented. The proposed method is rigorously and systematically applicable to any dynamic system with nonlinear polynomial elements. Starting from two identical nonlinear algebraic systems, the proposed approach determines a proper bidirectional coupling that is able to force the coupled systems to exhibit complex behaviours. The coupling strength permits to control bifurcations of the system, i.e., to move through different regions of the parameter space, characterized by different complex behaviours of the system. Among the analyzed complex phenomena (generalized synchronization, blowout bifurcation, on-off intermittency and hyperchaos) a particular relevance is given to hyperchaotic behaviour. Moreover the basic design principle is demonstrated by means of proper examples.
Contrasting In Vivo Effects of Two Peptide-Based Amyloid-β Protein Aggregation Inhibitors in a Transgenic Mouse Model of Amyloid Deposition

Previous studies have shown that 17,19,21-tri-N-methyl-Aβ16-22 peptide (Aβ16-22m), and a peptide analogue containing α,α-disubsituted amino acids (ααAA) in the hydrophobic core domain of Aβ, termed AMY-1, effectively inhibited full-length Aβ aggregation in vitro. To investigate the amyloid-modifying effects of these agents in vivo, we injected these compounds into the hippocampus of 13-month-old amyloid precursor protein (APP) transgenic mice, a model of amyloid deposition. After 7 days, brain tissues were stained for immunohistochemistry to detect total Aβ and thioflavine-S (THIO-S) to measure Aβ compact plaques. Both diffuse Aβ deposits and compact amyloid plaques were significantly increased when injecting 0.3 nmol Aβ16-22m compared to the PBS vehicle. The amyloid aggregation-modifying peptide AMY-1 showed a slight reduction of Aβ deposition in the injection area at a dose of 0.3 nmol, but neuronal toxicity, measured by Fluoro-Jade and Nissl stains, appeared when higher doses (3 nmol) were tested. Our data indicate that, unlike observations reported in vitro, the Aβ16-22m increased deposition of Aβ in the brain of APP transgenic mice in vivo. Possible explanations for this outcome include unique influences of the brain environment and/or modification of Aβ production or clearance by the administered agent. The AMY-1 peptide showed a trend for reducing Aβ deposits, but led to toxicity at higher doses. These data emphasize the need for evaluating potential Aβ aggregation inhibitors with in vivo models of amyloid deposition before assuming they will have benefit in treating Alzheimer's disease patients.
Women in Physics: Reversing the Exclusion

Two decades ago US women earned about 4% of the nation's physics PhDs. Today, they earn about 5%. Although discussed in various forums in recent years, the low representation of women in physics persists. The problem is especially perplexing given the dramatic increases in the percentages of women in other sciences and in engineering.
Roles of intracellular and extracellular calcium in the kinetic profile of adrenocorticotropin secretion by perifused rat anterior pituitary cells. II. Arginine vasopressin, oxytocin, and angiotensin-II stimulation.

We examined the effects of removing extracellular Ca2+ (Ca2+e), depleting intracellular Ca2+ (Ca2+i), inhibiting cAMP-dependent calmodulin, and blocking voltage-sensitive Ca2+ channels on the secretion of ACTH by perifused dispersed rat anterior pituitary cells. The cells were stimulated with synthetic arginine vasopressin (AVP), oxytocin (OT), and angiotensin-II (AII), all of which are thought to act via the Ca2+/inositol phosphate-dependent protein kinase-C pathway, with synthetic ovine CRF, which acts via the cAMP-dependent protein kinase-A pathway, and with dioctanoylglycerol, which directly activates protein kinase-C. All three secretagogues elicited an initial spike phase ACTH secretory response that peaked within 1 or 2 min and ended within 6 min. AVP and OT also elicited a sustained plateau phase response that lasted for as long as the cells were exposed to the secretagogue, but AII did not. Removal of Ca2+e diminished the initial spike phase by 30-50%, but depletion of Ca2+i virtually abolished it. In contrast, the sustained phase of the response to AVP and OT was abolished by removal of Ca2+e. The effect of dioctanoylglycerol, which elicits a sustained progressive increase in ACTH release, but no initial spike phase, was also greatly inhibited by Ca2+e removal; no greater effect was observed when Ca2+i was depleted. Blockade of L-type voltage-sensitive Ca2+ channels with nimodipine, a dihydropyridine drug, had the same effect as Ca2+e removal on both the initial spike and sustained plateau phases of the response to AVP. Inhibiting cAMP-dependent calmodulin with penfluridol had no effect on the initial spike phase, but reduced the sustained plateau phase of the response to AVP. Removal of Ca2+e or depletion of Ca2+i did not abolish the synergistic ACTH secretory response to the combination of AVP and CRF. (ABSTRACT TRUNCATED AT 400 WORDS)
Finding maximum rank moment matrices by facial reduction on primal form and Douglas-Rachford iteration

Recent breakthroughs have been made in the use of semi-definite programming and its application to real polynomial solving. For example, the real radical of a zero dimensional ideal, can be determined by such approaches. Some progress has been made on the determination of the real radical in positive dimension by Ma, Wang and Zhi[5, 4]. Such work involves the determination of maximal rank semidefinite matrices. Existing methods are computationally expensive and have poorer accuracy on larger examples. In previous work we showed that regularity in the form of the Slater constraint qualification (strict feasibility) fails for the moment matrix in the SDP feasibility problem[6]. We used facial reduction to obtain a smaller regularized problem for which strict feasibility holds. However we did not have a theoretical guarantee that our methods, based on facial reduction and Douglas-Rachford iteration ensured the satisfaction of the maximum rank condition. Our work is motivated by the problems above. We discuss how to compute the moment matrix and its kernel using facial reduction techniques where the maximum rank property can be guaranteed by solving the dual problem. The facial reduction algorithms on the primal form is presented. We give examples that exhibit for the first time additional facial reductions beyond the first which are effective in practice with much better accuracy than SeDuMi(CVX).
Online Multi Chemistry SoC Estimation Technique Using Data Driven Battery Model Parameter Estimation

Kalman filters have shown to be a very accurate and robust method for State of Charge estimation. However, their performance depends heavily on the accuracy of the used battery model and its parameters. These battery model parameters have shown to vary with the State of Health, cell chemistry, temperature and load current. This paper studies a data driven battery model parameter estimation technique based on the recursive least squares method as an alternative to extensively characterizing every cell of interest with time-consuming test procedures. The performance of two commonly used electrical models is compared and extensively validated on three different cell chemistries (Nickel Cobalt Manganese, Lithium Iron Phosphate and Lithium Titanate Oxide), under load conditions of varying dynamic nature representative for electric vehicle (EV) applications, using a Dynamic Discharge Pulse Test (DDPT) and the Worldwide harmonized Light vehicles Test Procedure (WLTP). The developed model is able to identify and update battery model parameters online, for three different chemistries, potentially reducing offline characterization efforts and allowing monitoring of battery electrical behavior and state estimation over its entire lifetime.
Antiapoptotic function of charged multivesicular body protein 5: A potentially relevant gene in acute myeloid leukemia

In recent years, RNA interference (RNAi) has been widely used to uncover gene function or pathway context of novel genes. In our study, we describe a short‐hairpin RNA‐based RNAi screening of a set of functionally uncharacterized human genes for their possible capability to inhibit apoptosis. We thereby identified a new antiapoptotic function for CHMP5 (charged multivesicular body protein 5), which was confirmed by overexpression and rescue assays. Furthermore, caspase assays showed that CHMP5 silencing induced caspase cascade activation mainly through extrinsic apoptosis pathway. Based on genome‐wide expression array profiling, a possible regulatory role of CHMP5 on apoptosis‐associated genes and different signaling pathways including nuclear factor kappa B was revealed. In addition, we found significantly higher CHMP5 mRNA levels in acute myeloid leukemia patients. This observation together with the antiapoptotic feature of CHMP5 suggests a possible oncogenic function for this gene in leukemogenesis.

This major enhancement of medical and health data available on mothers and infants can greatly expand the scope of research on pregnancy outcome in the United States.
A Study On Named Entity Recognition For Malayalam Language Using TnT Tagger & Maximum Entropy Markov Model

Information Extraction is the process of extracting the relevant data from the given text documents. It is one of the widely used research areas in Natural language processing. Named Entity Recognition(NER) deals with recognizing named entities(NE) such as person, organization, location in the text documents. In the existing system, TnT tagger is used for named entity recognition. The drawback is that there occurs a problem while handling the unknown words. Maximum entropy markov models have a drawback. It potentially suffer from the label bias problem. The lowentropy transition distributions effectively ignore their observations. This work implements a named entity recognizer for Malayalam language using Maximum Entropy Markov Model (MEMM). It combines the features of Hidden Markov models and Maximum entropy. It represents all these observations as arbitrary features such as capitalization, word, PoS, formatting). Input data for proposed Named Entity Recognition system is any text document related to the any domain in Malayalam language. Trigrams‟n‟tags (TnT) tagger is used for parts of speech (POS) tagging. The significance of the work is that it helps in smoothing and handling unknown words. The system is experimented with more than thousand sentences. An accuracy of 82. 5% is obtained for the proposed methodology.
Polymeric Controlled Drug-Delivery Systems: Perspective Issues and Opportunities

Although, the drug-delivery system (DDS) concept is not new, great progress has been made recently in the treatment of a variety of diseases. Targeting delivery of drugs to the diseased lesions is one of the most important aspects of DDS. To convey a sufficient dose of drug to the lesion, suitable carriers of drugs are needed. Polymers, which swell and contract in response to external pH levels, are being explored. The research in this area is being carried out all over the world at a great pace. Not only that new developments are emerging in the existing technologies, but also various new technologies are being developed and tested. Consequently, a huge amount of new information is available, which should be compiled and presented in a comprehensive way to benefit large numbers of users in this area as well as to help active research workers in the field. The purpose of this review is to discuss some recent advances and future prospects in controlled drug-delivery technology. The article serves as a useful tool for the beginners as well as for the researchers actively involved in this fascinating area of applied polymer science.
