Three-phase interleaved boost DC/DC converter with high voltage gain and reduced nominal value on power devices

In this paper, a new interleaved boost dc-dc converter is presented for PV applications. The proposed converter consists of three-phase which are parallel connected to each other. There are voltage multiplier units between the phases for increasing the output voltage. By increasing the voltage multiplier units (by connecting the series together), the output voltage will be more increase. In addition, the nominal value of the power components is reduced. Therefore, the voltage stress of switches and diodes for various duty cycles is low and so, the efficiency is high. One of the other advantages of the proposed converter input current ripple is low with the utilization of interleaving techniques. These advantages cause the proposed converter to be a good candidate for PV panels. To illustrate the merits of proposed converter, comparison results with other converters are provided. Also, theoretical analysis for two stages with operating at 25kHz is provided.

Re se arch of Optimized Algorithm about Mining Frequent Closed Itemsets

— Frequent closed patterns technique is used to extract smaller and most important frequent patterns. In existed algorithms, when finding frequent closed itemsets, a large amount of useless frequent itemsets will generated, which leads to high cost as well as ineffective. To solve this problem, we propose an optimized algorithm about mining frequent closed patterns without duplication. Several experiments have been implemented to compare the proposed algorithm with the existed algorithm. The results demonstrate that our proposed approach has better performance by reducing the number of frequent closed items without losing any information
Renewable energy resource self-intervention control technique using Simulink/Stateflow modeling

Hybrid Renewable Energy Complementary Systems are gaining popularity as electricity power generation system. The Hybrid Renewable Energy Complementary Systems introductory was to overcome the intermittency during the energy harvesting process. Therefore, solar photovoltaic and wind turbine generator has been seen as one of the most promising Hybrid Renewable Energy Complementary System to overcome the intermittency compare to a typical Hybrid Renewable Energy System. The integration of solar photovoltaic and wind turbine generator as Hybrid Renewable Energy Complementary System can play an important role to reduce the dependency on the fossil fuel for electricity power generation and are seen as a solution to improve the shortage of electricity due to increasing demand. Thus, the advantages of Hybrid Renewable Energy Complementary Systems have gained attention from many researchers around the world. Research to improve the complexity complementary system performance is necessary to achieve well design control and autonomous system operation and systematic energy management in the system. With that, this paper presents a new voltage-divider balancing switching technique to control the self-intervention switching for the Hybrid Renewable Energy Complementary System. The self-intervention control strategy of the Hybrid Renewable Energy Complementary System is coordinated using the Simulink/Stateflow process. The Simulink/Stateflow modelling performs under different preset conditions which are based on the analogue voltage reading from the input of the Hybrid Renewable Energy Complementary System resources. Simulation results demonstrate the validity of the proposed research to control the self-intervention of the Hybrid Renewable Energy Complementary System under the preset conditions.
Accuracy of gravitational waveform models for observing neutron-star--black-hole binaries in Advanced LIGO

Gravitational waves radiated by the coalescence of compact-object binaries containing a neutron star and a black hole are one of the most interesting sources for the ground-based gravitational-wave observatories Advanced LIGO and Advanced Virgo. Advanced LIGO will be sensitive to the inspiral of a 1.4M⊙ neutron star into a 10M⊙ black hole to a maximum distance of ∼900 Mpc. Achieving this sensitivity and extracting the physics imprinted in observed signals requires accurate modeling of the binary to construct template waveforms. In a neutron-star–black-hole binary, the black hole may have significant angular momentum (spin), which affects the phase evolution of the emitted gravitational waves. We investigate the ability of currently available post-Newtonian templates to model the gravitational waves emitted during the inspiral phase of neutron-star–black-hole binaries. We restrict to the case where the spin of the black hole is aligned with the orbital angular momentum and compare several post-Newtonian approximants. We examine restricted amplitude post-Newtonian waveforms that are accurate to third-and-a-half post-Newtonian order in the orbital dynamics and complete to second-and-a-half post-Newtonian order in the spin dynamics. We also consider post-Newtonian waveforms that include the recently derived third-and-a-half post-Newtonian order spin-orbit correction and the third post-Newtonian order spin-orbit tail correction. We compare these post-Newtonian approximants to the effective-one-body waveforms for spin-aligned binaries. For all of these waveform families, we find that there is a large disagreement between different waveform approximants, starting at low to moderate black hole spins, particularly for binaries where the spin is antialigned with the orbital angular momentum. The match between the TaylorT4 and TaylorF2 approximants is ∼0.8 for a binary with m_BH/m_NS∼4 and χ_BH = cJ_BH/Gm^(2)_(BH)∼0.4. We show that the divergence between the gravitational waveforms begins in the early inspiral at v∼0.2 for χ_BH∼0.4. Post-Newtonian spin corrections beyond those currently known will be required for optimal detection searches and to measure the parameters of neutron-star–black-hole binaries. The strong dependence of the gravitational-wave signal on the spin dynamics will make it possible to extract significant astrophysical information from detected systems with Advanced LIGO and Advanced Virgo.
Targeted pharmacotherapy in progressive familial intrahepatic cholestasis type 2: Evidence for improvement of cholestasis with 4‐phenylbutyrate

Progressive familial intrahepatic cholestasis type 2 (PFIC2) is a result of mutations in ABCB11 encoding bile salt export pump (BSEP), the canalicular bile salt export pump of hepatocyte. In some PFIC2 patients with missense mutations, BSEP is not detected at the canaliculus owing to mistrafficking of BSEP mutants. In vitro, chaperone drugs, such as 4‐phenylbutyrate (4‐PB), have been shown to partially correct mistrafficking. Four PFIC2 patients harboring at least one missense mutation (p.G982R, p.R1128C, and p.T1210P) were treated orally with 4‐PB and followed prospectively. Patient mutations were reproduced in a Bsep/green fluorescent protein plasmid. Cellular localization of the resulting Bsep mutants was studied in a hepatocellular line (Can 10), and effects of treatment with 4‐PB and/or ursodeoxycholic acid (UDCA) were assessed. In Can 10 cells, Bsep mutants were detected in the endoplasmic reticulum instead of at the canalicular membrane. Treatment with 4‐PB and UDCA partially corrected Bsep mutant targeting. With 4‐PB, we observed, in all patients, a decrease of pruritus and serum bile acid concentration (BAC) as well as an improvement of serum liver tests. Pathological liver injuries improved, and BSEP, which was not detected at the canalicular membrane before treatment, appeared at the canalicular membrane. Bile analyses showed an increase in BAC with 4‐PB. Patient conditions remained stable with a median follow‐up of 40 months (range, 3‐53), and treatment tolerance was good. Conclusion: 4‐PB therapy may be efficient in selected patients with PFIC2 owing to ABCB11 missense mutations affecting BSEP canalicular targeting. Bile secretion improvement may be a result of the ability of 4‐PB to retarget mutated BSEP. (Hepatology 2015) Hepatology 2015;62:558–566
Dielectric property analysis for the different charge defects in SiO2 based on the first principles

In this paper, we establish the different defects species and the different charge states models, including the intrinsic and extrinsic defects, in the alpha-quartz system. The models for different defects have been optimized within the first principles. Furthermore, the formation energies for defect structures in the alpha-quartz system have been computed. We can deduce the easiest generated defect in the alpha-quartz system through the formation energies as a function of the Fermi level. From the simulation results, it is concluded that Al3+-Na+ defect is the most possible defect type at the low temperature, and then at the high temperature, the interstitial O2- is the most possible defect type. Finally from the band structure, we also find thatalphathe interstitial O2- and Al3+-Na+ defect are the shallow defect level in the energy band. And they become the very important accept defects in alpha-quartz.
Estimating Habit Formation in Voting

We estimate habit formation in voting--the effect of past on current turnout--by exploiting transitory voting cost shocks. Using county-level data on U.S. presidential elections from 1952-2012, we find that precipitation on current and past election days reduces voter turnout. Our estimates imply that a 1-point decrease in past turnout lowers current turnout by 0.7-0.9 points. Consistent with a dynamic extension of the Downsian framework, current precipitation has stronger effects following previous rainy elections. Further analyses suggest that this habit formation operates by reinforcing the intrinsic satisfaction associated with voting.
Inoculum standardization in antimicrobial susceptibility testing: evaluation of overnight agar cultures and the Rapid Inoculum Standardization System

Using the Rapid Inoculum Standardization System [RISS; Minnesota Mining & Manufacturing Co. (3M Co.)], we investigated the use of overnight agar cultures in the preparation of inocula for disk diffusion and microdilution susceptibility tests and compared our results with susceptibility results obtained with the standard methods. The 3M system consists of an inoculation wand, with which a reproducible number of bacteria can be removed from an agar plate, and a diluent in which to suspend the organisms. We used 25 gram-positive cocci, 75 enteric and nonfermentive gram-negative bacilli, and 40 more fastidious bacteria (Haemophilus, Neisseria, and pneumococci) for the evaluation. The geometric mean inoculum size for all organisms tested was 9.7 X 10(7) CFU/ml by the standard method and 1.1 X 10(8) CFU/ml for the RISS. The categories of susceptibility obtained by both methods in the disk diffusion tests were comparable, as were the minimal inhibitory concentrations. We recommend that the use of overnight agar cultures and the use of the RISS to prepare inocula for susceptibility tests be acceptable alternative procedures in the standard methods for susceptibility tests.
Recurrence after first cerebral infarction in young adults

Objective– We have investigated recurrence of stroke in a consecutive series of young adults, aged 16 to 45 years, after a first cerebral infarction. Methods– From January 1, 1988 to December 31, 1996 we submitted those patients to a diagnostic protocol including angiographic, cardiological, and haematological investigations. The patients were followed at 6 month intervals up to December 31, 1998. Results– We have evaluated and followed‐up 135 patients, 71 men and 64 women, who were 3.99% of all the admitted stroke patients. At 12 months after stroke, 83 patients had returned to work, 40 patients were mildly to moderately handicapped, 4 were using a wheel‐chair, and 8 had died. Follow‐up was 26 to 123 months (mean 68.8). Recurrence of stroke, always of ischaemic nature, was seen in 15 patients (11.1%), 3 to 76 months after the first stroke (mean 27.4), for an annual incidence of 2.26%. Recurrence was significantly associated with Partial Anterior Circulation Syndrome and Haematological subtype of first stroke (respectively, P=0.0209 and P=0.0135, ξ2 test), but not with age (≤ or >35 years) or risk factors. Repetition of stroke was never fatal, but it caused heavy disability in 13 patients, 8 of whom had completely or nearly completely recovered after the first event. Conclusions– Our data suggest that recurrence of stroke is a major clinical problem also for the patients aged less than 45 years and that it might be more frequent with specific clinical syndromes and etiologic subtypes of first stroke.
Accelerating the computation of FLAPW methods on heterogeneous architectures

Legacy codes in computational science and engineering have been very successful in providing essential functionality to researchers. However, they are not capable of exploiting the massive parallelism provided by emerging heterogeneous architectures. The lack of portable performance and scalability puts them at high risk, ie, either they evolve or they are destined to be executed on older platforms and small clusters. One example of a legacy code which would heavily benefit from a modern redesign is FLEUR, a software for electronic structure calculations. In previous work, the computational bottleneck of FLEUR was partially reengineered to have a modular design that relies on standard building blocks, namely, BLAS and LAPACK libraries. In this paper, we demonstrate how the initial redesign enables the portability to heterogeneous architectures. More specifically, we study different approaches to port the code to architectures consisting of multi‐core CPUs equipped with one or more coprocessors such as Nvidia GPUs and Intel Xeon Phis. Our final code attains over 70% of the architectures' peak performance, and outperforms Nvidia's and Intel's libraries. On JURECA, the large tier‐0 cluster where FLEUR is often executed, the code takes advantage of the full power of the computing nodes, attaining 5× speedup over the sole use of the CPUs.
Design of a miniature axial flux flywheel motor with PCB winding for nanosatellites

This paper presents the design and analysis of an axial flux permanent-magnet (AFPM) machine for nanosatellites application. It is a miniature axial flux surface mounted permanent magnet flywheel motor, using a printed circuit board (PCB) stator winding. The PCB stator has simplified the design and construction and avoids unnecessary space, since size reduction has become one of the most important aspects of flywheel motor design for nanosatellites. The performances of the machine are estimated by combination method of three-dimensional (3D) electromagnetic finite element analysis (FEA) and approximate theoretical analysis. The back EMF and electromagnetic torque are derived. A comparison between the analysis and experimental measurement results of the prototype machine is also presented. Both simulated and experimental results show that the proposed motor would be an acceptable solution for the nanosatellite applications with advantages such as simple structure and low-cost, as multi-layer circuit board production techniques have made the production of printed circuit coils cheaper and easier.
Low pass filter installation for reducing harmonic current emissions from LED lamps based on EMC standard

Light Emitting Diode (LED) lamp has been widely used in Indonesia for a lighting system. However, LED lamp is a nonlinear load that caused high harmonics current. This paper is focused on reducing the harmonics current that caused by LED lamp with a driver. In order to reduce the harmonic current, low pass filter is applied to the system. The experiment result revealed a significant reduction of current harmonic which is fit in with IEC 61000-3-2 class C standard and good power quality of the system.
Broadening the scope on health problems among the chronically neurologically ill with the International Classification of Functioning (ICF)

Purpose. The aim of this study was to determine ICF items indicating health problems for patients with a chronic neurological disorder such as multiple sclerosis, Parkinson's disease and neuromuscular disease. Method. A Delphi study using three disease-specific panels composed of patients and proxies, medical and non-medical health professionals (N = 98). Panels were asked to select items from the International Classification of Functioning, Disability and Health (ICF) reflecting relevant disease-specific health problems. Items appraised as relevant by the panel members were compared with items in established measures namely: the Minimal Record of Disability (MRD) and the Disability and Impact Profile (DIP). Results. Sixty-eight ICF items were considered to be the most relevant, and belonged to four ICF domains. No significant differences were found between the appraisal of items by patients/proxies and health professionals. Agreement across the disease panels appeared to be (very) strong. Differences between the three disease-specific panels were found for the ‘Body Functions and Structures’ domain: consensus was reached by extension of the inclusion criteria. The ICF-item selection covers almost all items of the established measures. The largest contrast was shown in the item selection for the ‘participation’ and ‘environmental factors’ domains. Conclusions. Selected items indicate a broader scope in studying health problems compared with widely used health status measures in neurology, especially for the ICF domains ‘Participation’ and ‘Environmental Factors’.
Remote and Autonomous Studies of Mobile and Ubiquitous Applications in Real Contexts

As mobile and ubiquitous applications become increasingly complex and tightly interwoven into the fabric of everyday life it becomes more important to study them in real contexts. This paper presents a conceptual framework for remote and autonomous studies in the field and two practical tools to facilitate such studies. RECON is a remote controlled data capture tool that runs autonomously on personal mobile devices. It utilizes the sensing and processing power of the devices to capture contextual information together with general usage and application specific interaction data. GREATDANE is a tool for exploration and automated analysis of such rich datasets. The presented approach addresses some key issues of existing methods for studying applications in situ, namely cost, scalability and obtrusiveness to the user experience. Examples and experiences are given from remote and autonomous studies of two mobile and ubiquitous applications where the method and tools have been used.
Progressive Decline in Nart Score with Increasing Dementia Severity

Although the National Adult Reading Test (NART) is widely used to estimate premorbid intellectual ability in adults with possible or probable dementia, it may be less resilient to the progress of Alzheimer's Disease (AD) than was initially assumed. This paper reports performance at four annual assessments of 78 people with either autopsy confirmed (n = 50) or clinical diagnosis of AD (n = 28). Results indicate that NART score does decline over time and that extent of decline is a function of MMSE score on entry to the study but is not dependent on age, education or time post onset of dementia.
Counting Fixed-Height Tatami Tilings

A tatami tiling is an arrangement of $1 \times 2$ dominoes (or mats) in a rectangle with $m$ rows and $n$ columns, subject to the constraint that no four corners meet at a point. For fixed $m$ we present and use Dean Hickerson's combinatorial decomposition of the set of tatami tilings — a decomposition that allows them to be viewed as certain classes of restricted compositions when $n \ge m$. Using this decomposition we find the ordinary generating functions of both unrestricted and inequivalent tatami tilings that fit in a rectangle with $m$ rows and $n$ columns, for fixed $m$ and $n \ge m$. This allows us to verify a modified version of a conjecture of Knuth. Finally, we give explicit solutions for the count of tatami tilings, in the form of sums of binomial coefficients.

Análisis de Variabilidad con Modelos de Objetivos

Dentro del campo de la variabilidad, o la habilidad de cambio o personalizacion de un sistema, no es comun que dicha variabilidad se tenga en cuenta en la definicion de requisitos. En las propuestas donde si se contemplan se utilizan directamente features, aunque no son una tecnica de elicitacion de requisitos, sino que mas bien estan a medio camino entre los requisitos y la definicion de la arquitectura. Tambien existen propuestas que usan casos de usos, mas cercanos a la elicitacion de requisitos, pero que tienen problemas para modelar la variabilidad. En este articulo se propone aplicar tecnicas de la Ingenieria de Requisitos (IR) al estudio de variabilidad utilizando un enfoque basado en modelos de objetivos, escenarios (incluyendo casos de uso) y features, para la especificacion y analisis de requisitos de sistemas con variabilidad. De esta manera, se espera mejorar la fase de requisitos en este tipo de sistemas. Ademas, los modelos de objetivos proporcionan un mecanismo de decision de alto nivel (los objetivos del usuario) y permiten incorporar los requisitos no funcionales (RNF).
Extra end effect of axially segmented stator core of high speed high power permanent magnet electric machines

Stator core of high speed high power permanent magnet machines can be segmented in the axial direction, so that air flow can be forced through the gap between the core segments in order to enhance the cooling condition. Extra end effect thus exists, which will be studied in this paper. First, a 3D FEA model of the stator segments with end windings is built to reveal the relationship between the segmentation gap length and the stator iron loss and the magnet eddy current loss. Then, considering the negative impact of the end effect, the stator core segmentation is optimized, thus the machine losses such as the eddy current loss in the magnets are reduced. The analysis and optimal design have been applied in a 39krpm 110kW PM synchronous motor.
