Dissipation through spin Coulomb drag in electronic spin transport and optical excitations

Spin Coulomb drag (SCD) constitutes an intrinsic source of dissipation for spin currents in metals and semiconductors. We discuss the power loss due to SCD in potential spintronics devices and analyze in detail the associated damping of collective spin-density excitations. It is found that SCD contributes substantially to the linewidth of intersubband spin plasmons in semiconductor quantum wells, which suggests the possibility of a purely optical quantitative measurement of the SCD effect in a parabolic well through inelastic light scattering.
CONTRASTING INTRANSITIVE MOTION IN ENGLISH AND SERBIAN: HOW DO WE BUILD ’SOUND’ EVENTS?

The paper addresses intransitive motion constructions in English and Serbian with the initial aim of identifying and explaining the structural (construction) templates , which are available in the two languages for intransitive motion encoding. The analysis is based on the well - known proposal by Leonard Talmy (1975, 1985, 1991, 2000) that languages fall into two main types as to how they encode motion events. Special attention is devoted to English and Serbian verbs of emission (VE) (specifically verbs of sound and verbs of light emission), regarding their potential to surface as verbs of motion and combine with directional phrases within motion event constructions. The analysis aims at contrasting both verbal sub-subclasses in English and Serbian for the purpose of identifying the relevant points of similarities and divergences between the two language systems being analysed. The theoretical claims of the analysis are empirically supported by a contrastive sentential corpus which further promotes the claim that the potential of VE is wider in scope than was initially proposed by Levin (1993).
Context-aware multimodal Recurrent Neural Network for automatic image captioning

Automatic image captioning is a state-of-the-art computer vision task where any image can be described with text. There are cases where an image is supported by text in for instance books or news articles. In this study a context-aware model is proposed that uses not only the image, but also the text surrounding the image to generate a description. The model uses a joint LSTM with attention on both the image and the context and is trained on the Microsoft COCO dataset. This study also explored several setups to represent the text into a feature vector. Results show quantitative and qualitative improvements when context is included. Future directions are automating the feature crafting as well as applying the model to more datasets.
Determination of the ampacity of buried cable in Non-Homogenous environmental condition by 3D computation

Finite Volume Method (FVM) is chosen to calculate the heat transfer field and the heat generation with in the cable and heat dissipation in the surrounding soil of a three phase 145kV underground cable brunch that make it possible to analyze the ampacity of the cable. FLUENT as the proper software in this field is used to generate and solve the problem. Non-homogenous environment is considered for cable ampacity calculation and results are compare with homogenous environment condition function of the duration of the current circulating in the conductors. There are three standardized ampacity ratings: steady state, transient (or emergency) and short-circuit. Only steady state ampacity ratings are discussed in this paper. As providing analytical solution for complex situation is very indirect and in many cases the experimental method may preferred, in these condition numerical method as FVM is more pragmatic and cost effective. This paper focuses on the numerical techniques for the computation of cable ampacity in steady-state through the use of assumptions that simplify the problem. Finite Volume Method (FVM) is chosen to calculate the heat transfer field and heat generation with in the cable and heat dissipation in the surrounding soil. FLUENT as a proper software in this field is used to generate and solve the problem, FLUENT 6.3 (13). Most of the researches in this field are for homogenous area (soil) condition in order to simulate the actual soil in this paper a three dimensional model of the cable in full size and non-homogenous surrounding area is designed in FLUENT. Results are compared with the homogenous area condition.
Effects of Classification Techniques on Medical Reports Classification

Text classification is the process of assigning pre-defined category labels to documents based on what a classifications has learned from training examples. This paper investigates the partially supervised classification approach in the medical field. The approaches that have been evaluated include Rocchio, Naïve Bayesian (NB), Spy, Support vector machine (SVM), and Expectation Maximization (EM). A combination of these methods has been conducted. The experimental result showed that the combination which uses EM in step 2 is always produces better results than those uses SVM using small set of training samples. We also found that reducing the features based on tf-tdf values is decreasing the classification performance dramatically. Moreover, reducing the features based on their frequencies improve the classification performance significantly while also increasing efficiency, but it may require some experimentation
A Multiband Printed Log-Periodic Dipole Array for Wireless Communications

A multiband printed Log-periodic dipole array (LPDA) antenna for wireless communications is presented. The antenna has been designed starting from Carrel’s theory, optimized using CST Microwave Studio 2012, and then realized. The comparison between simulated and measured results shows that the proposed antenna can be used for wireless communications both in the S (2.4–3 GHz) and in the C (5.2–5.8 GHz) frequency bands, with very good input matching and a satisfactory end-fire radiation pattern. Moreover, it has a compact size, is very easy to realize, and presents an excellent out-of-band rejection, without the use of stop-band filters, thus avoiding interference out of its operating frequency band.
Corporate Cash Holdings and Financial Crisis: Evidence from Jordan

The focal point of this study is to investigate whether the Jordanian companies hold more cash after the financial crisis compared to before the financial crisis and which theories can explain these cash holdings. This work addresses the following questions: 1) what determine the corporate cash holdings in Jordan in normal time and during crisis. 2) How do the financial crises affect the policy of cash holding in the Jordanian firms? This study investigates the effect of capital expenditure, profitability, cash flows, investment (growth) opportunities, leverage, and ability to access capital markets, dividend’s payment and liquid assets substitutes. The study use data from 47 industrial companies listed at Amman Stock Exchange (ASE) during the period 2001 to 2011, with total 517 firm-year observations. The study time period was divided into four sub periods to assess the changes in cash holdings during each period. Panel regression was applied to examine the study model; also ANOVA test was used to test the differences in means for each sub period. Our results show that; Jordanian companies tend to increase their cash holdings because of financial crisis by increasing debt, decreasing investment activity and reducing payouts to shareholders. Moreover, the study show a different patterns in cash holdings during the pre crisis period and the post-crisis period, also there is a different patterns in cash holdings during the base period and the pre-crisis period. In addition, the main theories that explain the changes in cash holdings for the Jordanian companies were trade off theory and the pecking order theory. Generally speaking, our results support the trade off theory. The precautionary motive founded to be the most important motives for the Jordanian firms to hold cash. Generally, Cash flow, liquid assets substitutes, degree of financial leverage and dividend payment policy are the most important determinants of corporate cash holdings in Jordan.
PEMFC Optimization Strategy with Auxiliary Power Source in Fuel Cell Hybrid Vehicle

one of the present-day implementation of fuel cell is acting as main power source in Fuel Cell Hybrid Vehicle (FCHV). This paper proposes some strategies to optimize the performance of Polymer Electrolyte Membrane Fuel Cell (PEMFC) implanted with auxiliary power source to construct a proper FCHV hybridization. The strategies consist of the most updated optimization method determined from three point of view i.e. Energy Storage System (ESS), hybridization topology and control system analysis. The goal of these strategies is to achieve an optimum hybridization with long lifetime, low cost, high efficiency, and hydrogen consumption rate improvement. The energy storage system strategy considers battery, supercapacitor, and high-speed flywheel as the most promising alternative auxiliary power source. The hybridization topology strategy analyzes the using of multiple storage devices injected with electronic components to bear a higher fuel economy and cost saving. The control system strategy employs nonlinear control system to optimize the ripple factor of the voltage and the current and using the AOC-EMS system to improve the hydrogen consumption rate. ECMS and BERS strategy based on Time-Triggered Controller Area Network (TTCAN) also promoted to optimize hydrogen consumption rate from recovered kinetic energy while in braking regeneration mode.
GUIDING THE DEVELOPMENT OF ENTERPRISE DESIGN APPROACHES

Enterprise engineering (EE) is an emerging discipline that aims to address several phenomena in the evolution of an enterprise. Previous research highlighted a particular phenomenon that requires more research — i.e., the inability of the enterprise as a complex socio-technical system to adapt swiftly to rapidly- changing environments. Although there are numerous theoretical design approaches (with their own methodologies, frameworks, and modelling languages), there is little empirical evidence about their effectiveness. Furthermore, research indicates that multiple enterprise design approaches are used concurrently in industry, with each approach focusing on a sub-set of stakeholder concerns. The proliferating design approaches do not necessarily explicate their conditional use in terms of contextual prerequisites and demarcated design scope; and this also impairs their evaluation. This article provides guidance for the construction of design approaches that will enable researchers to contribute to the systematic growth of the EE knowledge base.

NGC 2571: An intermediate-age open cluster with a White Dwarf candidate

CCD UBVI imaging photometry was carried out in the field of the open cluster NGC 2571. From the analysis of our data we state the cluster is at a distance of 1380 ′ 130 pc and its age is 50′10 × 10 6 yr. The cluster mass function has a slope larger than a typical Salpeter's law. There are two notorious features in NGC 2571: the cluster contains a high proportion of stars located below the reference line that are serious candidates to be metallic line stars (probably Am-Fm), and shows also a sharp gap along its main sequence that cannot be explained by a random process nor by a biased rejection of cluster members. A striking blue object was detected in the cluster field that could be a white dwarf candidate.
Tuning FCM Parameters with AMOSA

Clustering of attack patterns is used in intrusion detection and discussed in this paper. Fuzzy CMeans (FCM) is a popular method for clustering; the performance of FCM is depends to its parameters radically. In this paper, performance of FCM is evaluated with some Validity Indices and represented in a multi-objective optimization problem. Multi-Objective Simulated Annealing (AMOSA) has high power to solve multi-objective optimization problems, so it is used in this paper to tune the parameters of FCM.
Third places and the interactive construction of interculturality in the English as foreign/additional language classroom

Based on the assumption that the construction of interculturality in third places is essential for foreign/additional language teaching and learning, this paper aims at discussing how these third places are interactively constructed in real classrooms. In order to achieve that objective, I will first review some theoretical studies that have dealt with the construction of third places and interculturality in the classroom. Then, the methodological procedures will be explained. After that, I will contextualize, analyze and compare some real classroom episodes taken from different studies pointing out their different interactional features. The findings show that the episodes investigated present two types, having either an ‘essentialist cultural orientation’ or an ‘intercultural orientation’. In the former orientation, the episodes cannot be considered third places as culture is an object constructed as an entity in its own right (Liddicoat & Scarino, 2013). On the other hand, in the latter orientation, third places seem to be constructed as teachers and learners are seemingly interactively engaged in the practice of meaning-making by confronting different points of view.
ARE THE TURKISH EXTERNAL DEFICITS SUSTAINABLE? EVIDENCE FROM THE COINTEGRATING RELATIONSHIP BETWEEN EXPORTS AND IMPORTS

This paper aims to understand the recent history of Turkish external imbalances by examining the long-run tendency of the Turkish trade balance. The size of the Turkish external deficits especially during the 1990s has worried politicians, academicians and the general public. Following recent work in the field, the paper examines the sustainability of the external deficits in the long-run by employing the cointegration framework.
Low Power Multiplier Design for Polyrate Filterwith Reduced Area and High Speed Design

Multi-rate Signal processing consideration pre-owned in Digital Signal processing systems carry sample rate conversion.Systems with different input and output sample ratesare used this type of technique. In multi rate signal processing applications very adequate and attractive techniques are Interpolation and Decimation. This paper come up withefficient area minimization with high speed and low power efficient VLSI architecture for polyphase decimation filter having decimation factor as three (D=3) using Booth multiplier. We also multiply signed numbers by using booth multiplier. In this algorithmthere are individualkey performance metrics those are number of slices, maximum operating frequency, number of LUT’s, input output bonds, power consumption, setup time, hold time, propagation delay between source and destinations are estimated for the filter of length nine (N=9). The power bender is diminished inpolyphase decimation filter using Boothmultiplier which preoccupieslow-power when correlated to the conventional multiplier. By using carry look-ahead adder we can improve the speed. It was noticed that the proposed design provides increase in speed, reduction in area and slight reduction in power dissipation when set side by side to conventional and BFD multiplier and low complexity.
MINIATURIZED MULTIBAND MICROSTRIP PATCH ANTENNA USING METAMATERIAL LOADING FOR WIRELESS APPLICATION

A highly miniaturized significant gain triple band patch antenna loaded with a new modified double circular slot ring resonator (MDCsRR) metamaterial unit cell is presented in this paper. New MDCsRR is a compact low frequency slot ring resonator. The principle of the proposed patch antenna element is based on adding series capacitance to decrease the half wavelength resonance frequency, thus reducing the electrical size of the proposed patch antenna. The transmission line model is used to analyze passband and stopband characteristics of the radiating bands. Circulating current distribution around MDCsRR slot with increased interdigital capacitor finger length causes multiple modes to propagate. The MDCsRR metamaterial unit cell consists of a new modified circular slot ring resonator (MCsRR) with metallic strip finger. The proposed structure is compact in size with radiating element dimensions of 0. 20λ× 0. 20λ× 0. 008λ at first resonating frequency. The proposed antenna offers triple band operation with significant calculated antenna gain of 3.28 dBi at first center frequency of 3.2 GHz, 2.76 dBi at second center frequency of 5.4 GHz and 3.1 dBi at third center frequency of 5.8 GHz. The electrical size of the proposed antenna is miniaturized by about 68.83% as compared to the conventional patch antenna operating at first resonating frequency.
EVALUATION OF PUBLIC PERCEPTION TOWARDS MEDICINE QUALITY AND PRICES IN SIX ZONES OF AFGHANISTAN

This article is aimed at evaluating the Public Perception towards Medicine Quality and Prices in Afghanistan. A cross-sectional descriptive study involving (n = 12, 82) was conducted in six zones of Afghanistan with the response rate of 100%. During the analysis, it was found that high proportions 61.4% of Afghan doctors are prescribing quality medicines. The survey results have shown that nine out of ten (96.3%) respondents suggested that Afghan government should adopt health policies to control the medicine prices and expenditure. A similar high proportion agreed that higher medicine costs negatively affects patient outcomes (89.6%). It is strongly recommended by the respondents (93.1%) that prescription drug prices need to be regulated by the government. During the survey, it was strongly (94%) emphasized that all medicine prices need to be disclosed on the dispensed medicine label. As a conclusion, the government should take firm steps to control the quality and disparate medicine prices in the country. Unified medicine pricing policy is sought and the entry ports to be equipped with quality control staff, labs and warehouses. The medicine importing and dispensing bodies should be monitored against the performance metrics adopted.
Ecosystem fluxes of carbonyl sulfide in an old-growth forest: temporal dynamics and responses to diffuse radiation and heat waves

Abstract. Carbonyl sulfide (OCS) has recently emerged as a tracer for terrestrial carbon uptake. While physiological studies relating OCS fluxes to leaf stomatal dynamics have been established at leaf and branch scales and incorporated into global carbon cycle models, the quantity of data from ecosystem-scale field studies remains limited. In this study, we employ established theoretical relationships to infer ecosystem-scale plant OCS uptake from mixing ratio measurements. OCS fluxes showed a pronounced diurnal cycle, with maximum uptake at midday. OCS uptake was found to scale with independent measurements of CO2 fluxes over a 60 m tall old-growth forest in the Pacific Northwest of the US (45∘49′13.76′′ N, 121∘57′06.88′′ W) at daily and monthly timescales under mid–high light conditions across the growing season in 2015. OCS fluxes were strongly influenced by the fraction of downwelling diffuse light. Finally, we examine the effect of sequential heat waves on fluxes of OCS, CO2, and H2O. Our results bolster previous evidence that ecosystem OCS uptake is strongly related to stomatal dynamics, and measuring this gas improves constraints on estimating photosynthetic rates at the ecosystem scale.
Lipid Reserves of Lesser Scaup (Aythya affinis) Migrating Across a Large Landscape are Consistent with the “Spring Condition” Hypothesis

ABSTRACT. The “spring condition” hypothesis (SCH) states that nutrition during spring migration affects survival, reproductive success, and, ultimately, population size of migratory birds. The North American population of Lesser Scaup (Aythya affinis) has experienced a marked decline, apparently because of poor recruitment. An important prediction of the SCH is that female Lesser Scaup have low lipid reserves during spring migration. We previously reported that lipid reserves and body mass of females collected on migratory stopover areas in northwestern Minnesota in springs 2000–2001 were lower than those on the same areas in the 1980s and markedly lower than those collected at Pool 19 of the Mississippi River in 2000–2001, an important preceding stopover area. However, it was unclear whether these findings represented a site-specific result or a landscape-scale phenomenon. Accordingly, we examined lipid and body mass of 641 female Lesser Scaup migrating across seven eco-physiographic regions of Iowa, Minnesota, and North Dakota during springs 2003–2005. We found that lipids and body mass of females throughout the Upper Midwest were similar to or less than the low values documented in northwestern Minnesota in springs 2000–2001 and markedly lower than those of females at Pool 19 in springs 2000–2001. Accordingly, our results are consistent with a prediction of the SCH, because lipid and body mass of females are low throughout this large landscape, lower than at an important preceding stopover area, and lower than all historical values. Finally, our results suggest the potential for cross-seasonal influences of nutrition on recruitment and that a stronger management focus on spring migration habitats may be necessary for conservation and recovery of declining migratory birds, especially Lesser Scaup.
A high-sensitivity z-axis capacitive silicon microaccelerometer with a torsional suspension

This paper presents a new z-axis high-sensitivity silicon-micromachined capacitive accelerometer fabricated using a three-mask dissolved-wafer process (DWP). It employs capacitive sensing using overlap-area variations between comb electrodes and a torsional suspension system to provide high sensitivity without compromising bandwidth, full-scale range, or the pull-in voltage ceiling. Excellent electrical sensitivity is obtained by using high-aspect-ratio comb fingers with narrow air gaps of 2 /spl mu/m and a large overlap area of 12 /spl mu/m /spl times/300 /spl mu/m. Torsional suspension beams 150 /spl mu/m long with a cross-sectional area of 12 /spl mu/m /spl times/3 /spl mu/m are used to improve the mechanical gain. Simulations of the capacitance between sense fingers show a highly linear region over a wide 14-/spl mu/m tip deflection range. Accelerometers were fabricated and yielded sensitivities of 263-300 mV/g, a nonlinearity less than 0.2% over a range of -4 to +3 g, a full-scale range of -4 to +6 g, and pull-in voltages greater than 8 V. A 3 dB cutoff frequency of 35 Hz was measured in air. The calculated thermomechanical noise in the sensor is 0.28 mg over this bandwidth.
A NON-PDCH∞ OUTPUT FEEDBACK CONTROLLER DESIGN FOR T-S FUZZY SYSTEMS WITH UNKNOWN PREMISE VARIABLES AND CONTROL CONSTRAINTS VIA LMI

Constraints via LMI Mohammad Hassan Asemani, Vahid Johari Majd Abstract: In this paper, non-PDC H ∞ observer-based controller design for disturbed T-S fuzzy systems with unknown premise variables is addressed for the first time. Unlike the available non-PDC-based approaches, real state variables are not used in the controller equation. Moreover, using the descriptor redundancy approach, the observer and controller gains are calculated by solving some strict linear matrix inequalities (LMIs). A fuzzy Lyapunov function approach is utilized to obtain less conservative design conditions than previous methods. Furthermore, in order to satisfy an arbitrary upper bound on the absolute value of the control signal, additional design conditions are obtained which depend on the upper bounds of the initial states of the observer. The effectiveness of
