Theoretical study of the structural , elastic and thermodynamic properties of chalcopyrite ZnGeP 2

The structural, elastic, and thermodynamic properties of ZnGeP2 with chalcopyrite structure are investigated using the pseudo-potentials plane wave method based on the density functional theory with the generalized gradient approximation. The lattice parameters (a, c and u) are directly calculated and agree well with previous experimental and theoretical results. The obtained negative formation enthalpy shows that ZnGeP2 crystal has strong structural stability. We have also calculated the bulk modulus B and the elastic parameters (C11, C12, C13, C33, C44, and C66) which have not been measured yet. The accuracy and reliability of the calculated elastic constants of ZnGeP2 crystal are discussed. In addition, the pressure and temperature dependencies of the lattice parameters, bulk modulus, Debye temperature, Grüneisen parameter, entropy, volume thermal expansion coefficient, and specific heat capacity are obtained in the ranges of 0–20 GPa and 0–1200 K using the quasi-harmonic Debye model. To our knowledge this is the first quantitative theoretical prediction of the thermodynamic properties for ZnGeP2 compound and still awaits experimental confirmations. & 2015 Elsevier Ltd.

PID CONTROL OF HYBRID AC / DC MICROGRID INVOLVING ENERGY STORAGE AND PULSED LOADS

In This paper presents PID control of hybrid AC/DC micro grids involving energy storage and pulsed loads. Grid isolated hybrid microgrid applications require special considerations due to the intermittent generation, online energy storage control and pulsed loads. In this work, we introduce a comprehensive frequency and voltage control scheme with pid for a hybrid AC/DC micro grid consisting of a synchronous generator, solar generation emulator and bidirectional (AC/DC and DC/DC) converters. A bidirectional controlled AC/DC converter, with an active and reactive power decoupling technique is used to link the AC bus with the DC bus while regulating the system voltage and frequency and tuning with PID controller. A DC/DC boost converter with a maximum power point tracking (MPPT) function is implemented to maximize the intermittent energy generation from solar generators. Current controlled bidirectional DC/DC converters are applied to connect each lithium-ion battery bank to the DC bus. Lithium-ion battery banks act as energy storage devices that serve to increase the system resiliency by absorbing, or injecting, power. Simulation results are presented for verification of the introduced hybrid AC/DC power flow control scheme.
Essential Oil Composition of Salvia . Rhytidea from Taftan

The chemical composition of the essential oil obtained by hydrodistillation from the aerial parts of Salvia rhytidia was analyzed by employing GC-MS technique.

Measuring and understanding performance in the mobile Internet

In the past decade, mobile Internet access has gone from limited capacity and reliability 2G, to 4G technologies with high speed Internet access. Mobile phones have also evolved from simple voice and text devices to smart phones and tablets with ample resources that have dramatically improved user experience and popularity of smart devices. The combination of fast Internet access and powerful mobile devices has contributed to a rapid shift from desktop computers to smart devices for everyday online activities, hence an ever growing demand for fast and reliable mobile connectivity. The increase of mobile Internet usage brings its own challenges. For example ISPs are having a difficult time keeping up with the growing demand and have often relied more on traffic management policies and resource allocation optimization rather than expanding their capacity. In order to make advancements in mobile networks, we need tools to give us more visibility into these networks to understand their performance and unique properties that differ from fixed-line networks. In my thesis, I will provide tools and measurement techniques and results to improve visibility into mobile network performance from two different perspectives: a)understanding mobile network operator policies and b)understanding transport layer performance as seen from mobile clients. First, I develop techniques and tools that shed lights onto mobile network operator policies without requiring any special access to devices or ISPs. This is important because mobile networks are not transparent about their traffic management policies, and the impact of these policies on users’s experience is poorly understood. This is largely because mobile networks and devices are locked down and opaque, and my work demonstrates that it is possible to overcome this limitation. Next, I propose to apply my differentiation detecting technique to conduct a case study of a recent instance of controversial differentiation: T-Mobile’s new service BingeOn. Finally, I propose to investigate Google’s new experimental transport protocol, QUIC, and perform an extensive analysis on how HTTP/S traffic over QUIC compares to TCP based protocol in a mobile network. This work can help to improve QUIC to address unique properties of the mobile environment.
ASSOCIATION OF VIABILITY OF MYOCARDIUM WITH PARAMETERS OF HEART RATE VARIABILITY IN PATIENTS OF FIRST ANTERIOR MYOCARDIAL INFARCTION

Background & Objective: Heart rate variability (HRV) is depressed after acute myocardial infarction (MI) and has been considered as a powerful predictor of mortality and arrhythmic complications in patients of MI. The present study was done to evaluate whether presence of viable tissue within the akinetic myocardium in MI patients, as assessed by dobutamine stress echocardiography (DSE), has any influence on the parameters of HRV. Methods: 51 patients with anterior wall ST elevation myocardial infarction (STEMI) treated conservatively underwent DSE two weeks after the index event of MI for assessment of myocardial viability. HRV recording was done for 20 minutes in these patients. Results: Out of 51 patients, 26 were DSE positive and 25 were DSE negative for viable myocardium. Among DSE positive group, the first 25 patients were taken for comparative analysis. Only the time domain parameters of HRV were significantly high in patients in the DSE positive group as compared to that observed in DSE negative group. On logistic regression analysis, only pNN50 (with p value = 0.021) could make a significant contribution for prediction of myocardial viability in the patients of MI. When pNN50 value increased by one unit, it was 1.43 times more likely to predict viable myocardium. Conclusion: The presence of viable myocardial tissue in akinetic segments among patients of first anterior wall STEMI influences the time domain as well as frequency domain HRV measures. HRV could be used as a potential screening tool to detect myocardial viability in patients of MI.
THE EFFECT OF WHEELS AND WHEELHOUSES ON THE AERODYNAMIC FORCES ACTING ON PASSENGER CARS

The aerodynamics of road vehicles has been improved through several decades to almost its optimum, regarding to the shape of the body. However, the unavoidable need for wheels caused and even recently causes significant problems for aerodynamicists to deal with. The addition of wheelhouses and rotating wheels to an aerodynamically optimized car body, leads to an increase in dragand lift coefficients by 30% and 40%, respectively. Several parameter tests were carried out by means of experiments on models and full scale cars but the attempts to describe the very complex flow were not successful. This article shows the way how wheels change the conditions of the flow around a simplified vehicle model and analyzes the change of forces acting on the different surfaces of the body. General conclusions are drawn from validated CFD results on the mechanism of effect of wheels and wheelhouses on the forces acting on road vehicles.
Embodied Energy and CO 2 Emission in Sino-Japan Trade

Along with the active trade in goods and services between China and Japan, energy use and environment issues also become complex. Under the support of Japan International Cooperation Agency (JICA), a multi-regional input-output table of energy use and CO2 emission for China and Japan is established in this paper. Based on the table, this study puts emphasis on the relation between Japan and China in energy use and CO2 emission in 2007 by employing a series of models. The paper not only evaluates the interregional impact of final demand on energy use and CO2 emission of China and Japan, but also proposes a method to evaluate the energy and CO2 embodied in bilateral trade using Multi-region input-output table. Besides, by supposing a non-trade scenario, the paper also estimates the effect of China-Japan trade on energy use and CO2 emission of China and Japan. The results indicate that for the same production in 2007 in bilateral trade, China not only has consumed more energy, but also has discharged more CO2 than Japan. In China-Japan trade of 2007, China is net importer of goods and services, but net ‘exporter’ of energy and CO2. The results also witness that China-Japan trade is helpful to reduce energy consumption and CO2 emission of China, while drive up that of Japan, but overall, the Sino-Japan trade is beneficial to the global environment.

*Corresponding Author: Phone: (248) 760‐9170 ; E‐mail: abigailbauerfinney@gmail.com ABSTRACT First‐year students living in collegiate residence halls (n=303) completed a survey about dining center usage and perceived social support, and granted access to first semester grade point average (GPA) and dining center usage data. Par cipants reported social benefits of ea ng with others and ea ng in the dining center. A significant posi ve rela onship was noted between frequency of ea ng in the dining center and GPA (p=0.000). Frequency of ea ng with others was found to be significantly posi vely correlated to perceived social support (p=0.000). Frequency of ea ng with others was significantly posi vely correlated with GPA for males (p=0.046) and females (p=0.020).
Recognition of Road Markers in In-Vehicle Camera Images using Subspace Method with Generative Learning

As the ITS technology evolves, many works on recognition of the traffic circumstances. The recognition of road markers is one of them. In the paper, we propose a recognition method for road markers taken by an in-vehicle camera. A road marker in an in-vehicle camera image appears differently depending on the distance to the angle of the camera and the road marker, namely, geometrical position relation. Therefore, the recognition is difficult in a real environment. Our method attempts to improve the recognition ability of road markers under various conditions, by artificially generating numerous learning image considering change of appearance. We call this approach, “generative learning”. In the generation process of the learning images, we modem a road marker by considering the factor of the change of appearance in real environment. For recognition, we used subspace method. The effectiveness of the proposed method was confirmed through a recognition experiment of actual road marker including changes of appearance.
Analysis of Existing Web Protocols for Trusted Contents Deliverable : D 1 . 1

This document aims at analyzing the existing web protocol with respect to the support they offer for realizing trustworthy content on the Internet as well as what limitations they pose for such a goal. To this end, we first lay out the principles of how we think one could achieve trustworthy content. In a nutshell, solution proposes to add metadata to the content that allows users to assess to what extend the content is trustworthy. The basic idea here is that entities who process the content (generate, modify, distribute,.) bind assertions about to the content to it. These assertions together with additional knowledge about the processing entities (which essentially are again assertions made by some entity), should allow users to assess the trustworthiness. We then list the relevant existing web protocols and discuss them in context of our architecture and solution sketch. Our conclusion is that the limitations of the current web protocols are not severe but that substantial work is required to implement our architecture.
Development of Macro-Encapsulation System for Pancreatic Islet Transplantation using 3D bioprinting

Transplantation of pancreatic islets is an attractive treatment for Type 1 Diabetes Mellitus [1]. However, islet transplantation has several challenges including function-loss associated with dispersion and host immune system [1]. Cell encapsulation is considered as a promising solution to protect islet from the in vivo environment. Macroand micro-encapsulation are representative strategies. Macro-encapsulation includes large amount of islets in a single package [2]. In this study, we suggest the macro-encapsulation system produced using 3D bioprinter. Further, this system will be coupled with micro-encapsulation system (dECM bioink) and it has potential to applied to other endocrine cells such as leydig cells.
ucan effect on CHO cell proliferation and migration eonardo

Fucan is a term used to denominate sulfated l-fucose rich polysaccharides. Here, a heterofucan, named fucan B, was extracted from the Spatoglossum schröederi seaweed. This 21.5 kDa galactofucan inhibited CHO-K1 proliferation and migration when fibronectin was the substrate. Fucan B derivatives revealed that such effects depend on their degree of sulfation. Fucan B did not induce cell death, but promoted G1 vailable online 25 May 2013
Delay Sensitive Distributed Sensor Data Exchange for an IoT

Publish Subscribe Message Oriented Middleware or PSMOM is widely deployed in the IoT. This uses message brokers to enable open and distributed sensor data publishers (or pub) and sensor data subscribers (or sub) to exchange information asynchronously using loosely-coupled pub-sub mechanisms. Existing PSMOM messaging systems ignore the different delay requirements of different types of sensor data and thus may introduce unexpected delays to time critical sensor data, which results in a delay for critical decision making. To address this challenge, a delay sensitive aware workload management framework for PSMOM is proposed. The framework extends an existing state-of-the-art messaging system, PEER, by adding support for workload allocation, a Queue Depth load metric, and dynamic load thresholds, enabling end-to-end latency guarantees and avoiding unnecessary load balancing. The validation using a simulation is also presented in the paper.
Named Entity Recognition Using Bidirectional LSTM CRFs Based on the POS Tag Embedding and the Named Entity Distribution of Syllables

개체명 인식이란 문서 내에서 인명, 기관명, 지명, 시간, 날짜 등 고유한 의미를 가지는 개체명을 추출하 여 그 종류를 결정하는 것을 말한다. 최근 개체명 인식 연구에서는 bidirectional LSTM CRFs가 가장 우수 한 성능을 보여주고 있다. 하지만 LSTM 기반의 딥 러닝 모델은 입력이 되는 단어 표상에 의존적이기 때 문에 입력이 되는 단어 표상을 확장하는 방법에 대한 연구가 많이 진행되어지고 있다. 본 논문에서는 한 국어 개체명 인식을 위하여 bidirectional LSTM CRFs모델을 사용하고, 그 입력으로 사용되는 단어 표상을 확장하기 위해 사전 학습된 단어 임베딩 벡터, 품사 임베딩 벡터, 그리고 음절 기반에서 확장된 단어 임베 딩 벡터를 사용한다. 음절 기반에서 단어 기반 임베딩 벡터로 확장하기 위하여 bidirectional LSTM을 이용 하고, 그 입력으로 학습 데이터에서 추출한 개체명 분포를 이용하였다. 그 결과 사전 학습된 단어 임베딩 벡터만 사용한 것보다 4.93%의 성능 향상을 보였다.
Renouncing Privacy in Crisis Management? People's View on Social Media Monitoring and Surveillance

Social media is used during crises and disasters by state authorities and citizens to communicate and provide, gain and analyze information. Monitoring of platforms in such cases is both a well-established practice and a research area. The question, whether people are willing to renounce privacy in social media during critical incidents, or even allow surveillance in order to contribute to public security, remains unanswered. Our survey of 1,024 German inhabitants is the first empirical study on people’s views on social media monitoring and surveillance in crisis management. We find the willingness to share data during an imminent threat depends mostly on the type of data: a majority (63% and 67%, respectively) would give access to addresses and telephone numbers, whereas the willingness to share content of chats or telephone calls is significantly lower (27%). Our analysis reveals diverging opinions among participants and some effects of sociodemographic variables on the acceptance of invasions into privacy.
Approximate Dimensional Synthesis of Watt-I Mechanism based on Twenty Precision Points Path Generation

In this paper, a six-bar, single degree of freedom, Watt-I mechanism has been dimensionally synthesized to solve the problem of path generation. The mechanism consists of revolute pairs and is capable to trace the prescribed path which comprises of twenty precision points. In the synthesis process, the standard dyad/triad and analytical loop closure equations are generated in terms of complex number mathematics. A MATLAB code is used to solve these equations for twenty coupler displacement positions and determine the lengths and orientations of various links of the mechanism. The overall dimensional synthesis of Watt-I mechanism has been demonstrated on a numerical example. SAM application software is also employed to verify the results.

Modular Distributed Architecture for Robotics Embedded Systems

Tomorrow, advanced transportation robotic applications have to be able to cope with various situations and perform many different tasks in a dynamic and changing environment. Furthermore, finding concrete applications in a wide range of user oriented industrial products, such systems, embedding several computing units, have to cope with an increasing demand of interactivity and to support number of non-critical pieces of hardware and software. This whole set of different capabilities needs to be performed reliably and safely over long time periods. To this aim not only advanced programming techniques, but also appropriate control architectures are required. For these reasons, Robosoft proposes both a set of hardware and software components developed from our own experience in the field of automatic transportation of people and goods, which can be easily adapted to robotic solutions for outdoor risky interventions.
7 Traits Associated with Invasiveness in Alien Plants : Where Do we Stand ?

Any organism must be equipped for life in a given environment, otherwise it will die. The fundamental question is how well does an organism need to be “equipped”, or what syndrome of traits must it possess to survive and flourish at a given locality. In the current human-mediated biodiversity crisis, where alien species play an important role, we need to know whether some species are inherently better equipped to become invasive when moved to new areas by humans. If so, we can identify such species and consider management options to prevent, or at least reduce the damaging effects of biological invasions. Despite the importance of chance and timing in the establishment and spread of alien plants (Crawley 1989), invasions are clearly not entirely random events (Crawley et al. 1996). Much of the early work on invasions was directed at collating traits associated with invasiveness (Booth et al. 2003). The question of whether is it possible to determine a set of traits that predispose a species to be invasive has been a central theme since the emergence of invasion ecology as a discrete field of study (Richardson and Pyšek 2006). Many studies have attempted to profile successful invaders, starting with Herbert Baker’s attempt to identify the traits of an “ideal weed” (Baker 1965), an idea now considered simplistic (Perrins et al. 1993). Baker defined as a weed a plant growing “entirely or predominantly in situations markedly disturbed by man (without, of course, being deliberately cultivated plants)”. To him, weeds included plants that encroached onto agricultural land (agrestals), and those occurring in waste places (ruderals; Baker 1965). There was no explicit reference to the status of the species as being native or alien. Perhaps it was the two species pairs he used to document different traits of “weedy”
Characterization of Films Immobilized on an Electrode Surface Using the Electrochemical Quartz Crystal Microbalance

(QCM) is a well established method for the measurement of small changes in mass, based on the relationship between changes in mass of materials attached to the crystal and the oscillation frequency of the crystal. One more recent application of the QCM is its coupling with electrochemical measurements (EQCM) in order to measure mass changes associated with electrochemical processes such as adsorption, electrodeposition, corrosion, and equilibration of redox polymers undergoing charge transfer reactions (1-4). This note will briefly discuss the principles of the EQCM and its application to the investigation of the behavior of electroactive films that have been immobilized on an electrode surface. The EQCM is based on the piezoelectric behavior of a quartz crystal; that is, the deformation of the crystal in the presence of an electric field. An alternating electric field is applied between two metal electrodes (typically gold) deposited on opposite crystal faces (e.g., the two circular faces of a disk), which gives rise to an oscillation of the crystal parallel to these surfaces. The resonant frequency of this oscillation (f0) is inversely related to the thickness of the quartz; for example, a crystal with a thickness of 320 μm has a resonant frequency near 5 MHz. If the mass of the crystal increases (e.g., by adsorption of material to one of the electrode surfaces), then the resonant frequency will also change. The relationship between the changes in mass per unit area (∆m) and frequency (∆f) are given by the Sauerbrey equation, which assumes that the combination of the crystal and adsorbed mass behaves as a rigid assembly:
