Compensation of Voltage Flicker by Using Facts Devices

Voltage flicker occurs when heavy loads are periodically turned on and off in a weak distribution system. If the distribution system’s short circuit capacity is not large enough, voltage fluctuations will occur. Voltage flickering can be extremely harmful to sensitive electronic equipment. Computerized equipment requires stable voltage to perform properly. This paper covers the contrasting approaches; dealing with the voltage flicker mitigation in three stages and assessing the related results in details. Initially, the voltage flicker mitigation, using FCTCR (Fixed Capacitor Thyristor Controlled Reactor), was simulated. Secondly, the compensation for the Static Synchronous Compensator (STATCOM) has been performed. In this case, injection of harmonics into the system caused some problems which were later overcome by using 12-pulse assignment of SATCOM and RLC filters. The obtained results show that STATCOM is very efficient and effective for the flicker compensation. All the simulations have been performed on the MATLAB Software

Backward Spectral Characterization of Liquid Crystal Display Based on Forward Spectral Characterization

A backward spectral characterization for Liquid Crystal Display by the use of rule for the maximum peak of spectral radiation curves changing with the digital input values is proposed; this new model is developed based on forward spectral characterization. It deals with estimation of RGB used as input to the digital display from known spectral radiation curves. We first investigate the rule for the peak of spectral radiation curves changing with the digital input values of primaries; then the initial digital input RGB are calculated based on that rule using the known spectral radiation curves . Third, RGB are inputted into forward spectral characterization model and the corresponding spectral radiation curves are predicted. Last, RGB are modified according to the difference between predicted and known , until this difference satisfied the prediction accuracy of the inverse characterization model. The inverse model has the advantage of using the same model for both forward and inverse color space transformation. This improves the accuracy of the color space transformation and reduces the source of errors. Results for 3 devices are shown and discussed; the accuracy of this model is considered sufficient for many applications.
Spectroscopy of Massive Stars in NGC 6822 and M33

We present blue spectra of massive stars in the Local Group galaxies NGC 6822 and M33. For all the targets, selected from our previous Hubble Space Telescope WFPC2 photometry, no previous spectroscopic studies exist, to our knowledge, except for a bright Wolf‐Rayet star in NGC 6822. Photospheric parameters Teff and gravity are derived by a model fit of the Balmer lines and multiband (UV to optical) photometry combined and are compared with evolutionary models. Inferred masses range from ≈7 to ≈40 M⊙ in the sample. From the spectroscopy, we classify the Wolf‐Rayet star in NGC 6822 as WN3(‐4), with no hydrogen. We estimate its progenitor mass of ≈40 ± 10M⊙. For two stars in the NGC 6822 sample, our data are not sufficient to establish whether they are foreground stars toward NGC 6822 or they belong to the galaxy.

Comparison of the Effectiveness of Audit Committees in the UK and Turkish Banks

The audit committee effectiveness (ACE) has been researched for several times by academics in accounting and finance literature in terms of relationships with earnings management, corporate governance mechanism, power types and, audit fee etc. This study aims to measure of the emphasize of effective audit committees (ACs) on bank performance via using some of the main bank performance indicators which are return on asset (ROA), return on equity (ROE) and net interest margin (NIM) in the Turkish and the UK banks during 2006-2010.
Effect of initial conformation, flow strength, and hydrodynamic interaction on polymer molecules in extensional flows

Brownian dynamics simulations are used to study the unraveling process of polymer molecules in dilute solutions under strong elongational flows. We follow chain extension, segmental alignment, and viscosity contribution behavior of individual, randomly coiled, freely jointed bead–rod chain model molecules. In the absence of hydrodynamic shielding, segmental orientation at an intermediate strain rate begins only when aided by overall chain extension. However, at a very high strain rate, rapid initial segmental orientation and lateral chain compression precedes overall chain extension, resulting in the formation of sharp folds in most chains. Fold formation during the extension process is characterized by a sudden decrease in the rate of overall chain extension, an intermediate plateau in birefringence, and a disproportionately low chain end-to-end distance. Hydrodynamic screening generally slows down the uncoiling process, sometimes enough to avoid the formation of folded conformations.
Dynamos in rotating compressible convection

Motivated by open questions in fundamental dynamo theory, the overall aim of this paper is to investigate some of the properties of dynamo action in rotating compressible convection. We study dynamo action in a convective layer of electrically-conducting, compressible fluid, rotating about the vertical axis. In order to identify the effects of rotation, we also carry out an equivalent set of calculations of convectively-driven dynamo action in a non-rotating layer. Whether or not the layer is rotating, the convection acts as a small-scale dynamo provided that the magnetic diffusivity is small enough. Defining the magnetic Reynolds number in terms of the horizontal scales of motion, we find that rotation reduces the critical value of this parameter above which dynamo action is observed. In the nonlinear regime, a rotating dynamo calculation and a separate non-rotating simulation are found to saturate at a similar level, even though the mid-layer value of the local magnetic Reynolds number is smaller in the rotating case. We compute the Lyapunov exponents of the flow to show that the stretching properties of the convection are modified by rotation. Furthermore, rotation significantly reduces the magnetic energy dissipation in the lower part of the layer.

Comparison of Feature Reduction Techniques for the Binominal Classification of Network Traffic

This paper tests various scenarios of feature selection and feature reduction, with the objective of building a real-time anomaly-based intrusion detection system. These scenarios are evaluated on the realistic Kyoto 2006+ dataset. The influence of reducing the number of features on the classification performance and the execution time is measured for each scenario. The so-called HVS feature selection technique detailed in this paper reveals many advantages in terms of consistency, classification performance and execution time.
Study on the Reactivity of Amino Acid Chemosensor, NPFNP, with Ethanol: Structural Elucidation through Single Crystal XRD and DFT Calculations

A novel ethoxy derivative of an amino acid chemosensor, 3-naphthyl-1-phenyl-5-(2ʹ-fluoro-5ʹ-nitrophenyl)-2-pyrazoline (NPFNP), has been synthesized and characterized by different spectroscopic methods. A single crystal of the ethoxy derivative, 3-naphthyl-1-phenyl-5-(2ʹ-ethoxy-5ʹ-nitrophenyl)-2-pyrazoline NPENP, has been obtained and characterized. The structure holds interest as it carries biologically active pyrazoline as a central ring attaching to electron donating and withdrawing substituents. The major motivation for this work was to gain detailed insight into the structural parameters of this compound for investigating the influence of crystal packing and geometrical dimensions on optical properties. Time-dependent DFT calculations have been employed for comparing the XRD data with theoretical parameters. The results show that the DFT method at B3LYP/6-31G level can well reproduce the structure of the title compound.
Performance scaling of Shor's algorithm with a banded quantum Fourier transform

In excellent agreement with our numerical simulations of Shor’s algorithm, equipped with a truncated quantum Fourier transform of bandwidth b, we find that its performance scales ∼2−ξbn, where n is the number of qubits, ξb = 1.1 × 2−2b, and the bandwidth b is the number of quantum states coupled by the quantum Fourier transform. Nonexponential behavior is observed for small n and explained analytically. The large-n exponential scaling implies that b = 7 is sufficient to operate a 1000-qubit quantum computer running Shor’s algorithm on the 95% performance level and implies hardware savings of the order of half a million rotation gates.
Investigation of Attitudes and Perceptions of Human Resource Managers at Hospitality Establishments Regarding Affirmative Action Programs A Case Study in Eskişehir-Turkey

The purpose of this study is to examine the perceptions and attitudes of human resource managers at some hospitality organisations regarding the employment of disadvantaged individuals as part of affirmative action program in the province of Eskisehir-Turkey. This study is a qualitative study focusing on real cases to inspire other organisations. The data were collected through active interviews, and the collected data was analysed through the use of manual qualitative data analysis methods. The findings of the study reveal that perceptions of human resource managers regarding disadvantaged individuals at hospitality organisations are closely related to disabled individuals. They do not have positive attitudes towards the employment of disadvantaged individuals in tourism as part of affirmative action programs. They are also against positive discrimination of disadvantaged individuals in the employment in tourism for some reasons. All these findings suggest that participants are confused about some terms regarding affirmative action.
Transgenic Potato (Solanumtuberosum) Expressing Two Antifungal Thionin Genes Confer Resistance To Fusarium Spp.

Two thionin genes were isolated from Arabidopsis thaliana (AT1G12660 and AT1G12663). The resulted thionin protein has antifungal activity against potato pathogenic fungi like Fusariumsolani and Fusariumoxysporum. These two thionin genes were respectively inserted into pEGAD vector. After that transformed into Agrobacterium tumifaceins GV3101::pMP90 in order to be transformed into the two potato cultivars (lady and spunta) using nodal cutting technique of tissue culture.Expressions of thionin transgenes in the transgenic plants were confirmed by RT-PCR. There were two assays were applied to test the role of thionins (in the transgenic potatoes) in resistance to the pathogenic fungi: effect of spore suspension on potato organs and the inhibitory effect of thionin proteins on spore germination.As the transgenic potato plant possesses active defense systems and can protect themselves from pathogenic invasion by secretion of a variety of small antifungal proteins such as thionins. The resulted transgenic potato cultivars were tested for fungal infection in comparing to control by using spore suspension on leaf and micro-tuber. The results showed that transgenic potato cultivars were highly resistant to the symptoms comparing to control.The other bioassay was studying the effect of the expressed thionin protein in the transgenic potato against the spore germination of both F. solani and F. oxysporum. There was obvious decrease in the number of the germinated spores comparing to control.

Responses of Algal Cells to Engineered Nanoparticles Measured as Algal Cell Population, Chlorophyll a, and Lipid Peroxidation: Effect of Particle Size and Type

This paper investigated toxicity of three engineered nanoparticles (ENP), namely, Al2O3, SiO2, and TiO2 to the unicellular green algae, exemplified by Pseudokirchneriella subcapitata with an emphasis on particle size. The changes in pH, cell counts, chlorophyll a, and lipid peroxidation were used to measure the responses of the algal species to ENP. The most toxic particle size was TiO2 at 42 nm with an EC20 of 5.2 mg/L and Al2O3 at 14–18 nm with an EC20 of 5.1 mg/L. SiO2 was the least toxic with an EC20 of 318 mg/L. Toxicity was positively related to the surface charge of both ENP and algae. The chlorophyll content of the algal cells was influenced by the presence of ENP, which resulted in limited light and availability of nutrients due to increase in turbidity and nutrient adsorption onto the ENP surface, separately. Lipid peroxidation was attributed to reactive oxygen species (ROS). Fast reaction between algal cells and ROS due to direct contact between TiO2 and algal cells is an important factor for lipid peroxidation.
Remote sensing and forest inventories in Nordic countries – roadmap for the future

ABSTRACT The Nordic countries have long traditions in forest inventory and remote sensing (RS). In sample-based national forest inventories (NFIs), utilization of aerial photographs started during the 1960s, satellite images during the 1980s, laser scanning during the 2000s, and photogrammetric point clouds during the 2010s. In forest management inventories (FMI), utilization of aerial photos started during the 1940s and laser scanning during the 2000s. However, so far, RS has mostly been used for map production and research rather than for estimation of regional parameters or inference on their accuracy. In recent years, the RS technology has been developing very fast. At the same time, the needs for information are constantly increasing. New technologies have created possibilities for cost-efficient production of accurate, large area forest data sets, which also will change the way forest inventories are done in the future. In this study, we analyse the state-of-the-art both in the NFIs and FMIs in the Nordic countries. We identify the benefits and drawbacks of different RS materials and data acquisition approaches with different user perspectives. Based on the analysis, we identify the needs for further development and emerging research questions. We also discuss alternatives for ownership of the data and cost-sharing between different actors in the field.
The Demand for Stocks: An Analysis of IPO Auctions

We analyze a unique dataset that includes the full demand schedules of 27 Israeli IPOs that were conducted as nondiscriminatory (uniform price) auctions. To the best of our knowledge, this is the first time the whole demand schedule for any asset is described. The demand schedules are relatively flat around the auction clearing price: The average elasticity is 27. The elasticity is low when the return distribution contains a large unique component. We also find a significant average abnormal return of 4.5% on the first trading day and a positive correlation between the abnormal return and the elasticity of demand.

NON-BUSINESS MARKETING REVISITED: THE ROLE OF CORPORATE SOCIAL RESPONSIBILITY IN HUNGARIAN ORGANIZATIONS

This paper aims to propose an unified model for non-business marketing including the marketing activities of organizations working in non-profit and profit oriented business sectors. At this purpose, we assumed that even when the marketing activities in non-profit, public and public utility organizations show certain specificities, almost all organizations develop them sharing the background aim of improving social welfare. Further objectives of the study were to explore the way which Corporate Social Responsibility (CSR) is incorporated in the sphere of non-business activities, and to describe how Hungarian organizations relate to CSR activities, as the results of previous exploratory researches in the country context pointed to a still rather poor implementation of responsible principles.
Service Quality, Customer Satisfaction and Loyalty in an Internet Service Providers

The current study aimed at examining the influence of service quality (internet service quality) on customer loyalty through the mediating effect of customer satisfaction. Through employing the questionnaire on a convenient sample of (860) consumer from different malls and commercial complexes in Amman – Jordan; the results indicated that internet service quality has a positive influence on customer satisfaction which in its turn can influence the level of customer loyalty. The study also reached to the results that good and well-built service quality may lead to customer satisfaction which in its turn can lead to a better level of customer loyalty. Consumer loyalty includes highlights or attributes that can fulfill the desires or needs of a client, it is a post utilization encounter which contrasts apparent quality and expected quality, in this way a similar conduct between inputs previously and after utilization. The study recommended to enhance the level of service quality awareness is the best approach to customer satisfaction. Aware employees tend to pay more attention to the idea of service quality which can lead to a better customer loyalty.
A Visual Environment to Study and Find Communities in Networks

In the last ten years, finding communities in networks, has been the subject of intense studies. If modularity maximization is still one of the mostly studied criterion, some criticism tend to arise and researchers in that field are more and more studying various criterion for finding communities in networks. To facilitate the task of studying various or new criterion, Constellation was developed. The software does not only allow an interactive definition of new criterion, it also provides a graphical interface and an optimization module that are useful tools for the researcher. This paper describes Constellation and its use. Résumé Durant les dix dernières années, trouver des communautés dans des réseaux a été l’objet d’intenses études.

A six-year isotopic record of lake evaporation at a mine site in the Canadian subarctic: results and validation

An isotopic method is applied in conjunction with a water balance method and the Penman combination method to estimate evaporation from a small, high closure (low outflow) lake near Yellowknife, Northwest Territories, Canada (62803 0 N 111824 0 W). The study provides baseline hydrological information for assessment of tailings pond design and management at nearby mine sites, and, notably, enables intercomparison of several field-based evaporation methods and a standard climate approach in a subarctic setting. A non-steady isotope mass balance method is applied to estimate evaporation over time intervals ranging from five days to three weeks, based on isotopic surveys of lakewater, groundwater, precipitation and atmospheric moisture during the open water periods of 1991 to 1996. Use of a relatively high precision non-steady technique, in contrast to the commonly employed approach assuming steady state, is feasible in the present setting owing to pronounced seasonal evaporative enrichment in lake water (20‐30 times analytical uncertainty of d 18 O). A comparative analysis reveals that the isotopic method is conservative relative to the Penman combination method, but less conservative than standard water balance, although estimates for the open water period are in agreement to within 20% in both cases. Interannual variability in evaporation is revealed to be 30‐50% greater than predicted from standard pan-to-lake algorithms, and of the same order of magnitude as the annual snow water equivalent (155‐175 mm), which has important implications for the design and management of tailings ponds in the area. #1998 John Wiley & Sons, Ltd.
