Sample with 35 system and equals with number of statistical community members and it includes all computer systems that have the mission to provide banking services to customers. Indices test questionnaire using multiple regression analysis has been done the Iranian state banks. Statistical analysis tools are also included Pearson correlation and beta coefficient. The findings of this study shows that the main reason for the failure of most information systems in Iranian banks is Issues and problems that the components of the operating and management strategies, expectations, complexity - the risk is occurring.
Optimal human capital policies under the endogenous choice of educational types

This study examines optimal human capital policies under non-linear labor and capital income taxes in the presence of consumption value of education in a two-period setting. We show that when individuals can choose educational types differing by the relative importance of consumption value and production value, education subsidies for low-type individuals should not equal an efficient level that offsets distortions induced by non-linear taxes on labor and capital income. Our findings imply that education policy does not restore efficiency, or the Diamond-Mirrlees production efficiency theorem fails. Moreover, capital income taxation is optimal, which means that the Atkinson-Stiglitz theorem breaks down.
Direct observations of the role of convection electric field in the formation of a polar tongue of ionization from storm enhanced density

We examine the relationship of convection electric fields to the formation of a polar cap tongue of ionization (TOI) from midlatitude plumes of storm enhanced density (SED). Observations from the geomagnetic storm on 26–27 September 2011 are presented for two distinct SED events. During an hour‐long period of geomagnetic activity driven by a coronal mass ejection, a channel of high‐density F region plasma was transported from the dayside subauroral ionosphere and into the polar cap by enhanced convection electric fields extending to middle latitudes. This TOI feature was associated with enhanced HF backscatter, indicating that it was the seat of active formation of small‐scale irregularities. After the solar wind interplanetary magnetic field conditions quieted and the dayside convection electric fields retreated to higher latitudes, an SED plume was observed extending to, but not entering, the dayside cusp region. This prominent feature in the distribution of total electron content (TEC) persisted for several hours and elongated in magnetic local time with the rotation of the Earth. No ionospheric scatter from SuperDARN radars was observed within this SED region. The source mechanism (enhanced electric fields) previously drawing the plasma from midlatitudes and into the polar cap as a TOI was no longer active, resulting in a fossil feature. We thus demonstrate the controlling role exercised by the convection electric field in generating a TOI from midlatitude SED.
Biliary complications in orthotopic liver transplantation: experience with a modified technique of duct-to-duct reconstruction

Biliary complications are described as frequent causes of morbidity during the postoperative course of orthotopic liver transplantation (OLTx), even in recent papers. The authors report here on their experience with duct-to-duct anastomosis as their method of choice for biliary reconstruction in a consecutive series of 100 OLTx in adult patients. The original technique, as described by Starzl, was modified by the authors by performing a wide, longitudinal plasty of both the donor and recipient bile ducts, joined together with two polidioxanone running sutures, producing the effect of a side-to-side anastomosis. This technique was used in all procedures, even when a significant discrepancy was evident between the ducts (n=10). Follow-up was completed in 100% of the patients for a period of 2–40 months (mean 13.1 months). Four major complications (4%) occurred including hepatic abscesses due to ascending cholangitis, T-tube dislocation, partial occlusion by a branch of the T-tube at the anastomotic site, and disruption of the bile duct after T-tube removal. In four other patients, transient abdominal pain followed removal of the stent. Neither strictures nor fistulas were observed. Choledochocholedochostomy on a T-tube stent represents, in our experience, the technique of choice for biliary reconstruction in OLTx. The procedure, as described in the present study, proved to be safe in preventing strictures and leakages and appears to be feasible in nearly 100% of all adult patients undergoing OLTx.
Optical-nanofiber-based interface for single molecules

Optical interfaces for quantum emitters are a prerequisite for implementing quantum networks. Here, we couple single molecules to the guided modes of an optical nanofiber. The molecules are embedded within a crystal that provides photostability and, due to the inhomogeneous broadening, a means to spectrally address single molecules. Single molecules are excited and detected solely via the nanofiber interface without the requirement of additional optical access. In this way, we realize a fully fiber-integrated system that is scalable and may become a versatile constituent for quantum hybrid systems.
Level of phobia towards Islam among non-muslim Students of Higher Educational Institution in Malaysia

This paper focuses on the level of phobia among non-muslim students of Educational Institution in Malaysia. In this paper, the history of islamophobia is also discussed briefly. Islamofobia is not a new issues in the world. Itâ? s already exist since the emergence of Islam (religion of Allah). Almost all the prophets, during their time faced rebellion and revolt from those who were against Islam. But the resistance towards the prophets were different based on the races, skills (given by Allah) and current situation. Almighty to Allah, all the problems, obstacles and resistance had been handled and settled wisely by the prophets. Anti Islam or islamophobia happened in the past and it is still there even today. Islamophobia increased after the terrific event in â? September 11, 2001â? Most of the muslims from western countries were treated badly. Fortunately, in Malaysia non-muslims live comfortabily and in harmony. But then, there are certain cases of islamophobia happen. Nevertheless, it is not serious. This paper analyses islamophobia among non-muslim students in Educational Institution. The purpose of this paper is to find out the level of islamophobhia among them. As for this paper, the level of phobia is categorized into three levels. The first stage is fear, second is hatred and third is threat. The three categories which have been analysed has been defined before by Zafar Iqbal (2010), Ponyting & Mason (2007) and Oxford Advanced Learnerâ? s Dictionary (2005). Malaysia is an Islamic Country and majority are muslims. So, knowing the level of phobia among non-muslim is very important to maintain the harmony and peaceful relationship among all races in Malaysia. The researched has been carried out by 250 set of questionaires to non-muslim students to know their level of phobia towards Islam. The data analysed using SPSS method and the result will be discussed in presentation and full paper.
Wireless Sensor Network and Its Security Concerns

Wireless Sensor Networks (WSNs) are used as one of the greatest vital part to collect information. The WSNs, which have speed and are simple to install and maintain, are going to survive in the real world scenario. Although in the earlier WSNs the security concerns are overlooked, but sensor networks are always used to deal with extremely sensitive content and such networks do not have much interaction with external environment while operating. In this paper first we are discussing the WSN architecture and its core element that is, Wireless sensors. Then we are emphasizing on the need for Wireless Sensors and what are the factors of consideration while selecting a wireless sensor. We also focus on discovering some major security concerns for WSN and proposed a few solutions for the same.
Earthquake distribution in southern Tibet and its tectonic implications

[1] A temporary 37-station seismic array was operated in southern Tibet from June 2004 to August 2005 close to Xigaze along a traverse from Tangra Yum Co rift in the west to Yadong-Gulu rift in the east. This lateral array of the international Hi-CLIMB project recorded a total of 885 local earthquakes during the 14-month deployment. Hypocenter locations of these events were obtained using HYPOINVERSE2000, and about half of them were relocated by the joint hypocenter determination method. Lateral variations in crustal seismic P and S wave velocities beneath the array were obtained simultaneously as part of the station corrections during the relocation procedure. While earthquakes were scattered in the region, more than 250 earthquakes were clustered within a small area at about 50 km north of the Indus-Yalu Suture and west of the Pumqu-Xianza rift. Crustal and uppermost mantle earthquakes are concentrated beneath the Himalayan crest. Projection of all earthquakes to a north–south profile shows that the subducting Indian plate passes the Indus-Yalu Suture below the Lhasa Terrane. While earthquakes are concentrated in the upper crust and upper mantle beneath the Himalayas, seismicity is mostly restricted to the upper crust to the north, which is consistent with a ductile middle/lower crust beneath southern Tibet. About 20 deep crustal and uppermost mantle events (at depths of 50–70 km) were observed to be associated with the subducting Indian lithosphere. Our relocation results of these local earthquakes in southern Tibet support the popular “jelly-sandwich” model for the rheology of continental lithosphere in which the strong seismogenic layers of upper curst and uppermost mantle are separated by a weak lower crust.
Effect on mechanical properties of aluminium alloy composites on adding ash as reinforcement material

To produce Al-matrix cast particle composites, wettability of the ceramic particles by liquid Al is essential. To improve wettability of the solution, few elements such as Mg and Si are added into Al melt to incorporate the ceramic particles. The present investigation has been focussed on the utilization of abundant available industrial waste such as fly ash and bagasse ash in useful manner by dispersing it into Eutectic Al-Si alloy LM6 Containing 10.58% Si to produce composites by liquid casting route. The mechanical properties such as Brinell Hardness and Ultimate tensile strength has been investigated. The test results of the mechanical properties have indicated that the ultimate tensile strength varies from 112.6 kN/mm­­­­ 2 to 180 kN/mm 2 with maximum value at 10wt % fly ash +10wt % bagasse ash and hardness varies from 52 BHN to 80 BHN with maximum value at 10wt% fly ash + 10wt% bagasse ash as reinforcement in the matrix metal. It was concluded that 10wt% fly ash +10wt% bagasse ash can be used as reinforcement in aluminium composites and the produced composites could be used in automobile industry for the production of lighter & strong engine blocks, pistons and other components.
A New Scheme for Storage and Retrieval of Shared Text Files

Recently, there has been an increasing need for storage spaces in the cloud centers. Efficient techniques for storing files can slow down this trend. In this paper, we investigate the problem of storing replicated text files that have been changed by different users, individually. Each user could annotate their document by providing shapes and artworks, each of which may include text. The proposed scheme is based on storing the changes made by each user in a separate file for that user. Experimental results demonstrate the efficiency of the proposed scheme in terms of reducing the utilized storage space. Particularly, the proposed scheme is more efficient when the number of users or file size increases.
Hypoglycemic and Antioxidative Effects of Functional Rice Goami and Nokwon in High Fat-Fed Mice

Effects of newly developed functional rice grains Goami (high-amylose rice) and Nokwon (green-kerneled rice) on the glucose metabolism and antioxidative defense system in C57BL/6N mice under high fat diet condition were investigated. Animals were randomly divided into five groups (n = 8) and given experimental diets for eight weeks: normal control diet (NC), high fat diet (HF), and high fat diet supplemented with white rice (HF-WR), Goami rice (HF-GR), and Nokwon rice (HF-NR). At the end of the experimental period, the HF group exhibited markedly higher blood glucose level, insulin concentration, plasma lipid peroxidation and lower hepatic glycogen concentration than that exhibited by NC group. However, diet supplementation of Goami and Nokwon suppressed the high fat diet-induced hyperglycemia and oxidative stress through inhibition of the glucose-regulating enzymes and enhancement of the antioxidant enzymes activities. The results illustrate that the new functional rice Goami and Nokwon may be useful in the development of functional foods with preventive effect against high fat diet-induced hyperglycemia and oxidative stress.
Modeling the Under-Actuated Mechanical System with Fractional Order Derivative

This paper presents the fractional order modeling of an under-actuated mechanical system. The under-actuated system taken in this paper is an overhead crane that has two degrees of freedom and one control input. The modeling equation is derived with the help of Euler-Lagrange equation. The proposed mathematical model is helpful in understanding the under-actuated mechanical system's fractional characteristics.
Atomistic simulation of interfaces: Proton transport across BaZrO3 grain boundaries

Due to the negative environmental effects of fossil fuels it is necessary to develop technology that may reduce or eliminate the need for oil and coal. Fuel cells are highly important in this context as they provide an efficient way of converting chemical energy into electrical energy. However, the development is hampered by a lack of electrolyte materials able to function at temperatures high enough to enable use of hydrocarbon fuels, yet low enough to avoid the wear on component materials caused by high operating temperatures. Solid oxide proton conductors are found to have several of the characteristics of a good electrolyte material in this temperature range, but increasing the conductivity to the level needed in practical applications remains a challenge. The aim of this thesis is to elucidate microscale phenomena that affect the performance of proton-conducting oxides. The material under investigation is BaZrO3, which is regarded as a promising electrolyte material due to its chemical stability and high grain interior conductivity. However, the grain boundaries in the material are highly resistive and lower the total conductivity. The cause of this high grain boundary resistivity has been investigated using atomistic simulations and thermodynamic modelling. Particular attention is devoted to the role of defect segregregation to the grain boundaries. From atomistic simulations it has been found that positively charged defects such as oxygen vacancies and protons segregate to the grain boundaires of BaZrO3. The accumulation of positive charge in the grain boundaries creates a potential barrier and leads to depletion of positive mobile defects from the surrounding region, impeding transport across the boundary. Thermodynamic models have been used to determine the height of the potential barrier resulting from segregation of positive defects, and the results compare well with experimental findings.
Impact of sustained-deficit irrigation on tree growth, mineral nutrition, fruit yield and quality of mango in Spain

Introduction. Mango (Mangifera indica L.) is a crop of major economic impor- tance in the provinces of Malaga and Granada (SE Spain). A field experiment on mango trees was designed to determine the optimum irrigation scheduling over three seasons. The aim was to evaluate the impact of sustained-deficit irrigation (SDI) strategies on fruit yield and quality, tree growth, and mineral status under a Mediterranean subtropical climate. Materials and methods. Three sustained-deficit irrigation treatments were applied to mango trees: SDI-1 (33% ETc), SDI-2 (50% ETc) and SDI-3 (75% ETc). The stress treatments were compared with a control (C-100) irrigated at 100% ET C. The response of fruit yield, number of fruits, fruit size and quality, and macro- and micronutrients in leaves was determined. Results. The SDI-2 treatment proved to be the most appropriate SDI treatment, since it allowed the trees to reach the highest yield (18.4 t·ha -1 ) and the best water-use efficiency (7.14 kg·m -3 ). However, fruit size was higher for trees of the SDI-3 and C-100 treatments, since they reached significantly higher length and width. The total soluble solids were affected by the SDI treatments only for one year, being highest in fruits from trees of the SDI-1 and SDI-2 treatments. Macro- and micronutrients in the leaves were affected by the SDI treatment only for the P, Mg and Mn contents. Conclusion. The SDI treatment providing 50% of ETC is recommended for mango orchards in order to attain the highest yields and the best water-use efficiency under a Mediterranean subtropical climate.

On the orders of automorphisms of a closed Riemann surface.

Let S be a closed Riemann surface of genus g ( > 2). It is known that the maximum value of the orders of automorphisms of S is 4g + 2. In this paper we determine the orders of automorphisms of S which are greater than or equal to 3g, and characterize those Riemann surfaces having the corresponding automorphisms. Except for several cases, such Riemann surfaces are determined uniquely up to conformal equivalence.
Exploring new coordination scenarios for workflows in the Amsterdam Police Force

In this paper we discuss the value of simulation-games as organizational change instruments. We present a case where new information and communication technology is introduced in the Amsterdam Police Force to enhance coordination and communication in workflows like handling firearm criminality or handling youth criminality. Policemen have participated in 9 occurrences of a social simulation-game where they perform daily tasks and explore new coordination scenarios. From our action research study we conclude that simulation-games provide more detailed insight in coordination issues than oral participatory design discussions. Furthermore we discuss how simulation-games can serve different interests in the different phases (unfreeze-rebalance-move-freeze) of an organizational change process.
Algorithmic Composition with Virtual Instrument in MATLAB and on FPGA

Music is an important part of most people’s lives; it is dominantly created by humans. In this thesis, an alternate source of music, which is hardware in the form of a field programmable gate array (FPGA), is presented. The designed FPGA can create and play its own music. The music is composed by an algorithm, which was developed in MATLAB by combining genetic programming concepts with music theory in order to increase performance of the composer. Initially, a population made of composition pieces created with respect to harmony, is generated. Later, the population goes through genetic processes resulting with the final composition. The fitness function that determines the individual’s ability to survive was optimized through listening tests. The virtual instrument was also developed in MATLAB as a waveform and an attack-decay-sustain-release (ADSR) envelope by recording and analysing an acoustic-electric guitar. The synthesizer like approach allows use of less circuit elements then does a physical model. Hardware implementation is done in a Xilinx University Program Virtex II-Pro board. The audio coder/decoder, AC97 is used as the interface between the digital-to-analog converter (DAC) and the circuit block that handles the composition. The sampling frequency in the FPGA implementation is kept at 9.765 KHz due to problems with the design suite and a smaller population is employed in order to fit into the FPGA. The compositional performance of the implementation in FPGA is comparable to the performance of the algorithm in MATLAB. This work shows that a portable music player that composes its own music seems a possibility in the future with improvements in compositional capability or the sound quality of the instrument. Introduction of a more complex generation conditions and a more complex elimination conditions could be an improvement. Another improvement would be to enable the creation of polyphonic compositions rather than monophonic compositions. On the instrument side, one possible improvement can be using industrially used sampled instruments.
Influence of phosphorus and silicon on lipia class production by the marine diatom Chaetoceros gracilis grown in turbidostat cage cultures

Production of intracellular and extracellular lipid classes by Chaetoceros gracilis was studied over a wide range of supply rates of inorganic phosphorus and silicon. The cage culture turbidostat, a continuous culture technique providing closely controlled nutrient concentrations and population densities, was used for growing the diatom. Nutrient, intracellular lipid and chlorophyll a analyses were performed over the whole range of nutrients used, but dissolved lipid production was measured only at the extremes of the ranges of nutrient concentrations. The production of triglycerides, a storage class of lipids, was triggered by nutrient stress with either phosphorus or silicon, as had earlier been demonstrated with nitrogen. The synthesis of phospholipids was reduced under phosphorus stress, while the synthesis of chlorophyll a was increased by silicon stress. The increase in chlorophyll a per cell under silicon stress brings into question the use of this pigment as a measure of biomass. Particulate lipid ye ld was highest in intermediate concentrations of both nutrients.
