Number of paper pages: 6
Abstract: Recently, owing to a high demand of and high dependence on electric power, the reliability of the distribution voltage of electric power systems has become more important. 22 kV high voltage cutout fuses have been used widely, but some melting accidents have occurred due to pollution/contamination of bushings. As the number of contaminants in bushings increases, the electric fields on the fuse element surface rise to a critical level, triggering corona discharge. A fuse element material that is more resistant to corona discharge than the Ag element is desired. A new type of current-limiting fuse made of stainless steel wires, which is low-cost and simple in design has been developed. Characteristics tests, including a blocking test with a high surge current when a voltage is applied, have been conducted. Using a model fuse, it was confirmed that this new type of fuse possesses similar performance characteristics to those with an Ag element.

Abstract: There are a lot of learning methods. As a general rule, the youth and especially the students see the advantages of the new technologies. We consider that the system of teaching must be redefined and oriented to allow a broader system of testing. The paper speaks also about the permanent learning and auto-education. In order to use the modern pieces of information, we have to be able to use the efficient ways of working with them.

Abstract: Nowadays, banks struggle to maintain their competitiveness and develop strategies to improve efficiency, by decreasing operational costs. Where multinational banks are concerned, the diversity of geographies usually multiplies the amount of repeated operations across borders, implying unnecessary costs. Banks are therefore starting to centralize some of their functions into shared-services centres where significant costs savings can be achieved. This paper analyzes the core areas within a bank, according to their potential of centralization, and provides a specific application to a European multinational bank with important international operations. Special focus is given to the Card Operations Department, in order to identify opportunities of centralization along the Group's operations.

Abstract: Nowadays humanity use about 50% of the existing potable water, but in the next 15 years this percentage will achieve 75%. Consequently the hydric stress risk will rise significantly across the entire planet. Accordingly several countries have to apply efficient hydric measures in the supply water sector, including at the building level. These measures beyond the water consumption reduction will contribute to increase the energy efficiency and to decrease the emission of greenhouse gases (GHG) specially the CO2 emissions. This paper is focused on the study of a region in the center of Portugal (Aveiro). Its aim is to assess the impact of efficient devices implementation in the water consumption facilities in the global urban water cycle, as well in the energy efficiency increase and in the decrease of GHG emissions.

Abstract: The present paper proposes two methods for constructing new asymmetric ZCZ sequence sets. ZCZ sequence sets are used as spreading sequences for AS-CDMA systems. An asymmetric ZCZ sequence set is a type of ZCZ sequence set and consists of multiple sequence subsets. Compared with conventional ZCZ sequence sets, the most important property of the proposed asymmetric ZCZ sequence sets is that the cross-correlation function between arbitrary sequences that belong to different sequence subsets has quite a large zero-cross-correlation zone. This property is useful for application to the AS-CDMA systems. If a cell is divided into concentric circles and each sequence subset is assigned to users existing in each area between two circles, then the proposed asymmetric ZCZ sequence sets can achieve much larger zero-cross-correlation zones than the conventional ZCZ sequence sets. The proposed asymmetric ZCZ sequence sets are expected to be useful for designing spreading sequence!

Abstract: Simulation tools help creating a low cost and efficient development of embedded system. SID is an open source simulator software that consists library of components for modelling hardware and software components. A component can be written in C/C++ and Tcl/Tk. Currently, the SID simulation toolkit only provides support for C++ and Tcl/Tk. Tcl/Tk is used to create GUI-based components. However, we have observed that Tcl/Tk components causing slow simulation response. Developing GUI using Tcl/Tk is also inflexible. Thus it is not proper for developing the cutting-edge products with rich graphics. In this work, we introduced the idea of Java as an alternative platform for developing components in SID. We enabled this possibility by developing a bridge module for SID using socket and JNI. SID API in Java is also proposed to ensure the compatibility and simplicity of SID components in Java.

Number of paper pages: 9
Abstract: Abstract: - Air pollution is considered to be the one of the most vital problem to all kinds of life. Air pollutants have no borders and can severely influence life on the planet earth. This work analyzes the air pollution yearlong hourly mean continuous data from one of the monitoring station located at the top of polyclinic in Al-Jahra city in the State of Kuwait. The measurements cover major pollutants such as carbon monoxide, methane, non-methane hydrocarbons (NM-HC) particulate matters (PM10) and nitrogen dioxide (NO2). Moreover, the data also include meteorological parameters, solar intensity, temperature, wind speed and wind direction. The seasonal variation for the year of 2008 is investigated (winter, spring, summer and autumn) for these pollutants. The data show daily averages and hourly maximum concentrations for each season of year 2008. The impacts of the diurnal variation of these pollutants and overall ambient air quality of this urban area in differ!
ent season have been presented in detail. The results confirmed that the road traffic was a major source of air pollution in the Al-Jahra area.

Abstract: The basic purpose of article is to find relationship between service quality, perceived value, customer satisfaction and repurchase intentions. The relationships between these variables are very complex so we will find the relationship in two models. First we simply check impact of each variable with other one. Secondly check that perceived value work as moderating variable between service quality and satisfaction or not. These all variables are very important for any manager to see that what matters a lot in order to satisfy customer. So, Critical indices are developed to identify critical factors of service quality and perceived value. This paper clarifies the dimensions of service quality and perceived value in hotel industry environment. This paper also compares that satisfaction or perceived value is better predictor of repurchase intentions. The last purpose is to check that is there any effect on these variables due to demographics variable like age, gende!
r, income, occupation. Survey Questionnaires are used to collect data from 125 luxury hotel customers of Pakistan. Instrument includes 59 items to measure all four variables. These variables are further subdivided into more dimensions for better measurement. SPSS 17 is used to do CFA and Regression analysis. First of all there are three dimensions of service quality discovered from this study. These dimensions are service consistency, service convenience and customer demand fulfillment. In perceived value, we find only two dimensions. These two dimensions are functional which is related with monetary value and other is symbolic which is related with social and emotional value. Secondly, this research finds relationship among service quality, perceived value, satisfaction and revisit intention in hotel industry. First of all the relationship between service quality dimensions and perceived value dimensions is significant.Then we find that perceived value and service quali!
ty have important and positive relationship with satisfaction and revi
sit intentions. Thirdly the perceived value and satisfaction both have positive relationship with repurchase intentions but satisfaction has stronger relation than perceived value. The paper is one of the first to provide critical factors which are important to improve service quality and increase perceived value. Secondly this paper is also first one to investigate the thorough relationship among all these important factors in Pakistani hotel industry context.

Title of the Paper: Extraction of Interpretable Rules from Piecewise-Linear Approximation of a Nonlinear Classifier Using Clustering-Based Decomposition

Abstract: This paper presents a novel approach for the extraction of interpretable rules from piecewise-linear approximation of any nonlinear classifier, e.g. Support Vector Machine (SVM). Recent major interest in kernel methods has drawn an attention to the extraction of human-tractable and interpretable rules from such state-of-art and hyperplane-based classifiers like SVM. Nevertheless, there is no clear understanding of the rule extraction routine from nonlinear SVM. The most comprehensible methods imply very complicated and indirect constraints that strictly enforce convexity of the searched-through half-space of inducted nonlinear classifier [1]. Apparently non-convex hyper-surfaces couldnt be effectively described by a finite set of convex rules without violating bounds of constrained non-convex area. In this paper we describe an approach for converting a widely acknowledged rule extraction algorithm for Linear Support Vector Machine [3] into a number of constrain!
ed linear programming (LP) problems. Stated LP problems incorporate finite number of linear constraints based on different individual decision hyperplanes to ensure piecewise-linear approximation of underlying nonlinearity. We claim that proposed approach helps to extract better rules from linearly non-separable cases and could be effectively employed even for non-homogeneous target classes with high inner variance.

Abstract: Abstract A rapid, precise, accurate, specific, and simple 19F NMR spectroscopic method was developed for to the quantitative determination of ofloxacin enantiomeric ratio in pharmaceutical formulations using chiral recognition reagents. Different parameters affecting the enantioresolution of ofloxacin were investigated including the type and concentration of chiral selector and concentration of ofloxacin. It seems that among the different chiral selectors studied (ƒΡ-, ƒ�-, £^- and hydroxyl propyl ƒ�- cyclodextrins, vancomycin and maltodextrin with dextrose equivalents of 4.0'V7.0, 13.0'V17.0 and 16.5'V19.5), vancomycin displays the highest resolution of 19F NMR signals of (R)- and (S)-ofloxacin at lower concentrations. For quantitative analyses, calibration curves were used. The liner ranges of calibration graphs were 0.05 - 0.18 mg mL-1 for both ofloxacin and levofloxacin (S-ofloxacin). The detection limits (S/N = 3) were 6.35 and 5.4 £gg mL−1 for ofloxac!
in and levofloxacin (S-ofloxacin), respectively. The recovery studies were performed on pharmaceutical samples by spiking known amounts of analyte. The recovery percentages ranged from about 97 to 107% with relative standard deviations of <8%. Statistical investigations represented insignificant difference between the real and measured contents at t95% confidence level.

Abstract: The issue of river pollution and its pollutants control is one of the most important topics, which has been brought for discussion in the recent years. For the purpose of effective control of river pollution, it is essential to study mixing and pollution transmission processes. For realization of this objective, there are models for analyzing parameters of flow, quality of water and other parameters of mix and transmission process. This paper studies the parameters effective in one dimensional distribution and transmission of pollutant wastewaters in river using MIKE 11. It is concluded that if the pollutant enters to the river from a source without time variations (continuously), the longitudinal distribution factor shall have no effect on the results of model and the pollutant transmits to downstream by the flow exclusively with saturated concentration; and longitudinal distribution will be significant if the pollutant enters to the river from a source with quick!
variations. Moreover, it is concluded that the hydrodynamic results effect severely on the results of distribution and transmission model and the hydrodynamic model must be calibrated well prior to solving distribution and transmission equations.

Abstract: There are a large number of power distribution transformer stations due to it is far away from city, wireless network, GPRS, and 3.5G single transmission device provides a good communication solution to supervise power transformer stations. This paper develops a novel device used to monitor on-line signal for power transformers. The measured-data is captured from multi-sensors and stored in the server equipment database. Besides, these data is used for the prediction of the power transformer life consumption. The transformer life consumption is satisfied with IEEE Standard. Various faults could occur in a transformer such as overload current, overheating, partial discharge and arcing, which can diagnose various fault-related conditions. According to the conventional way of the dissolved gas analysis, the fault is probably determined. As researcher knows, the IEC codes cannot determine the fault in many cases. Therefore, this paper presents a fuzzy logic tool that c!
an be used to diagnosis multiple faults in a transformer and monitor the trend. It has been proved to be a very useful tool for transformer diagnosis and customer servicing.

Email addresses of all the authors: hommalk@yahoo.com
Number of paper pages: 9
Abstract: Abstract: Withdrawal of water from a river into a canal involves the construction of a barrage or a dam across the river depending on whether the river is perennial or not. The design of the reservoir upstream of the dam and of the canal requires consideration of the sediment load carried by the river in case the river is sediment-laden. The basic equations concerning morphological changes in such rivers are discussed with particular reference to computation of reservoir sedimentation. The hydraulics of lined canals carrying wash load is examined from the point of view of limiting transport capacity and changes in frictional resistance. Lastly, the methods of design of sediment extraction devices like settling basins and vortex chambers are presented.

Abstract: This research focused on three questions. Is parent behavior related to children's technology use? Is children's technology use related to their creativity? Is parent behavior related to their children's creativity? The sample consisted of 490 parents and their 490 middle school children, 32% African American and 68% Caucasian American. Participants completed surveys as part of their participation in the Children and Technology Project. Findings indicated that parent behavior on the dimensions of warmth and control was unrelated to their child's technology use or creativity. One type of technology use was a strong predictor of multiple measures of creativity. Children who played videogames more were more creative than children who played videogames less.

Abstract: Abstract: - Every year, millions of people are suffering from bone defect arising from trauma, tumor or bone diseases. Therefore, there is a growing need for the development of biocomposites with excellent bioactivity and compatibility. In this study, nano-hydroxyapatite was elaborated by using polyvinyl alcohol (PVA) and polyvinylpyrrolidone (PVP) under mild temperature condition. Comparison with pure nano-hydroxyapatite prepared by precipitation method was investigated. The main goal is to highlight the effects of the introduction of polymers on the physico-chemical properties, morphology and on the chemical reactivity and bioactivity for applications in bony surgery. TEM showed a nanosphere hydroxyapatite with an average diameter 45 nm obtained by using PVA. Nano-rods HA with an average dimensions 13 nm width and 156 nm length were obtained by using, PVP. "In-vitro" physiological stability and solubility of the investigated samples was performed by soaking powde!
r in Simulated Body Fluid under physiological condition. Characterization by XRD, FT-IR SEM-EDS and ICP-OES were performed to identify phases, microstructure and then the chemical reactivity and bioactivity after soaking in SBF to evaluate the bioactivity kinetics. Crystals on the polymer fibril matrix exhibited certain orientation. Bone like apatite layer onto the surfaces is confirmed after post immersion in SBF by FT-IR, SEM-EDS and XRD. The polymer matrix controlled the dissolution precipitation reactivity with specific rate without change on the pH of the surrounding physiological body fluid.

Abstract: Abstract: - In order to increase the biocompatibility and bioactivity of bioactive glass, a biodegradable therapeutic polymer (Chitosan: CH) has been incorporated into bioactive glass (BG) to synthesize biocomposite material for applications in ortohpedic surgery. For this purpose, biocomposite based on bioactive glass and chitosan polymer was synthesized. The physico-chemical properties such as structure, link and morphology of the obtained biomaterials were characterized by using several physico chemical methods. The SEM studies showed that the bioactive glass particles were homogenously distributed within the matrix of chitosan polymer. The FTIR analyses indicated a good links between these two biomaterials. The bioactivities of the BG, of the BG/CH biocomposite were investigated by soaking of all powdered compounds in a simulated body fluid (SBF). The formation of a biologically active hydroxycarbonate apatite (HCA) layer on the surfaces of BG and also BG/CH !
biocomposite after immersion in SBF solution was illustrated. ICP-OES method was employed to evaluate the kinetic of bioactivity of these two biomaterials. The results indicated that the chitosan enhanced the bioactivity of bioactive glass. After three days of immersion, FTIR analyses confirmed the formation of this layer. The cytotoxicity and cell viability assays were also investigated by the MTT method using osteoblast like cells SaOS2. The results confirmed the absence of toxicity and a good cell proliferation on this biomaterial. However, the addition of chitosan in the glass matrix enhances the cell proliferation of about 5% after 6 days after culturing.

Abstract: Abstract: - In order to increase the biocompatibility and bioactivity of bioactive glass, a biodegradable therapeutic polymer (Chitosan: CH) has been incorporated into bioactive glass (BG) to synthesize biocomposite material for applications in ortohpedic surgery. For this purpose, biocomposite based on bioactive glass and chitosan polymer was synthesized. The physico-chemical properties such as structure, link and morphology of the obtained biomaterials were characterized by using several physico chemical methods. The SEM studies showed that the bioactive glass particles were homogenously distributed within the matrix of chitosan polymer. The FTIR analyses indicated a good links between these two biomaterials. The bioactivities of the BG, of the BG/CH biocomposite were investigated by soaking of all powdered compounds in a simulated body fluid (SBF). The formation of a biologically active hydroxycarbonate apatite (HCA) layer on the surfaces of BG and also BG/CH !
biocomposite after immersion in SBF solution was illustrated. ICP-OES method was employed to evaluate the kinetic of bioactivity of these two biomaterials. The results indicated that the chitosan enhanced the bioactivity of bioactive glass. After three days of immersion, FTIR analyses confirmed the formation of this layer. The cytotoxicity and cell viability assays were also investigated by the MTT method using osteoblast like cells SaOS2. The results confirmed the absence of toxicity and a good cell proliferation on this biomaterial. However, the addition of chitosan in the glass matrix enhances the cell proliferation of about 5% after 6 days after culturing.

Abstract: Abstract: - Every year, millions of people are suffering from bone defect arising from trauma, tumor or bone diseases. Therefore, there is a growing need for the development of biocomposites with excellent bioactivity and compatibility. In this study, nano-hydroxyapatite was elaborated by using polyvinyl alcohol (PVA) and polyvinylpyrrolidone (PVP) under mild temperature condition. Comparison with pure nano-hydroxyapatite prepared by precipitation method was investigated. The main goal is to highlight the effects of the introduction of polymers on the physico-chemical properties, morphology and on the chemical reactivity and bioactivity for applications in bony surgery. TEM showed a nanosphere hydroxyapatite with an average diameter 45 nm obtained by using PVA. Nano-rods HA with an average dimensions 13 nm width and 156 nm length were obtained by using, PVP. "In-vitro" physiological stability and solubility of the investigated samples was performed by soaking powde!
r in Simulated Body Fluid under physiological condition. Characterization by XRD, FT-IR SEM-EDS and ICP-OES were performed to identify phases, microstructure and then the chemical reactivity and bioactivity after soaking in SBF to evaluate the bioactivity kinetics. Crystals on the polymer fibril matrix exhibited certain orientation. Bone like apatite layer onto the surfaces is confirmed after post immersion in SBF by FT-IR, SEM-EDS and XRD. The polymer matrix controlled the dissolution precipitation reactivity with specific rate without change on the pH of the surrounding physiological body fluid.

Abstract: The focus of this study is to enhance the way of thinking that human activities cannot be separated from the functioning of the entire system on Earth. Learning from the Nature means to accept that the technical systems processes involving energy conversion and matter transformation need to be linked to environment engineering. This paper goes on to adopt a dualist view, incorporating technical and environmental dimensions, to describe exergy applicability to electrical ecosystems, since Industrial Ecology permits an alternate view of human applications, related both to technical and environmental reference systems

Title of the Paper: CLUSTERING WITH COMPLEX CENTERS
Authors as they appear in the Paper: Issam dagher

Abstract: Clustering analysis is the process of separating data according to some similarity measure. A cluster consists of data which more are similar to each other than to other clusters. The similarity of a datum to a certain cluster can be defined as the distance of that datum to the prototype of that cluster. Typically, the prototype of a cluster is a real vector which is called the center of that cluster. In this paper, the prototype of a cluster is generalized to be a complex vector (complex center). A new distance measure is introduced. New formulas for the fuzzy membership and the fuzzy covariance matrix are introduced. Cluster validity measures are used to assess the goodness of the partitions obtained by the complex centers compared those obtained by the real centers. The validity measures used in this paper are the Partition Coefficient (PC), Classification Entropy (CE), Partition Index (SC), Separation Index (S), Xie and Beni's Index(XB), Dunn's Index (DI) . I!
t is shown in this paper that clustering with complex prototypes will give better partitions of the data than using real prototypes.
Keywords: Clustering, prototype, complex center, validity measure.

Abstract: The goal of our prospective and controlled study was to dose the serum C reactive protein by Tina-quant immunoturbidimetric technique in parallel with leukocytes counting, in case of patients in the second gestational trimester with threatened abortion of unknown cause, that did or did not evolve towards spontaneous abortion during hospitalization, or with recurrent abortions in their priors, or with subclinical chorioamnionitis with or without broken membranes, or hospitalized for medical induction of the abortion for fetal reasons (such as retained dead fetus), or with acute pyelonephritis, subclinical mixed vaginitis or areolar mammary abscess, or with a normal pregnancy. Our results constantly indicate a significant (more accentuated after exogenous administration of prostaglandins in induced abortion) and maximum increase of serum CRP concentration (but not of the leukocytes number) at 24 hours postabortum, followed by a progressive decrease, of minimum 18%, !
of the same parameter, at 48 hours after non complicated second trimester abortion. Only the pregnancy complicated with high urogenital bacterial infections is accompanied by pathological values of the serum CRP (but not of the leukogram) that are significantly increased with respect to those from a normal pregnancy or one complicated with threatened abortion of unknown and non evolutive cause, or recurrent abortions in history. The obtained results suggest that a repeated measurement of the serum CRP concentration could be a valuable predictive marker for intrauterine infection, both in the late periabortum period as well as in the latency phase of the extremely premature rupture of the membranes or even when the fetal membranes are intact in the second trimester

Abstract: This paper presents a method to evaluate and improve the performance of gamma ray spectroscopy. Block diagram programming through VisSim environment is used to implement models for those devices. The benefits of using this modeling technique are the simplicity of carrying out the performance's measurement through computer simulation instead of setting up a practical procedure which becomes expensive as well as the difficulty of its management. The roles that the parameters of fabrication can play in the characteristics of gamma ray spectroscopy's are discussed through developed models implemented by VisSim environment. The present methodology shows that the electronic noise can be minimized by decreasing various effects such as leakage current, temperature, and 1/f spectral noise density. Moreover, an optimum value of the integration time and input capacitance was found to be 1.08μs and 0, respectively. Pileup model is implemented to reduce or eliminate this effect!
. In order to confirm our models and their validity on the practical applications, a comparison between the results obtained by proposed models and that experimentally published are conducted and full agreement is observed.

Abstract: Intelligent Transport Services (ITS) applications require availability of the seamless secure communications solutions covering usually wide areas and serving frequently extensive number of moving objects. Selectable levels of service quality are required in dependence on provided transport telematics service. There is available quite extensive range of wireless data services provided by public telecommunications providers frequently in quite reasonable pricing, however, with no guaranteed service quality. Studied telematics solutions expectations lead to the multi-path solutions where principal improvement in service quality is reached by systematic implementation of the telecommunications services quality management, efficient decision processes as well as appropriate flexible architecture. Complex approach has been adopted by ISO working group TC204, WG16.1 known as CALM family of standards. Related decisions processes are, however, not as deeply discussed in av!
ailable WG outputs as well as applied switching approach (L2) is rather complex for implementation. Authors, however, fully agreed with need of deep understanding of each applied alternative and precisely quantified requirements on its performance indicators. To cover high system requirements each applied technology was studied in detail to enable identification of specific performance indicators ranges as well as their internal interactions. Paper presents results of simplified heuristic decision processes pilot implementation build on technologies analysis. This pilot solution applies exclusively IP routing instead of the L2 switching approach. Obtained promising results represent relevant basis for the alternative solutions to CALM ideas based system with implemented below described complex adaptive decision processes.

Abstract: Surface properties of poly(1-butene) films has been modified by a radio frequency plasma treatment. To minimize degradation and ageing effects it is necessary adjusted the gas composition and the plasma conditions on the polymer type. For this purpose plasma containing five various gasses or their mixtures: air, argon, argon then allylamine, argon wearing ammonia and argon with octafluorocyclobutane, were used. Changes in the surface hydrophilicity, roughness and the chemical composition of modified poly(1-butene) films were investigated by contact angle measurements, atomic force microscopy and X-ray photoelectron spectroscopy. All types of plasma treatment expect fluorocarbon plasma cause increase of polar functional groups on the surfaces and their hydrophilicity. On the other hand, fluorocarbon plasmas cause increase of contact angle and hydrophobicity.

Abstract: A low cost, black nickel solar absorber coating used in thermal solar collectors on nanostructured high thermal conductor copper was analyzed using XPS (X-ray photoelectron spectroscopy) and MFM (magnetic force microscopy) techniques. Copper substrate nanostructuration was realized by electrochemical polishing to improve MFM analysis. Black nickel solar absorber coating was electrodeposited on nanostructured C81100 copper due to their good optical properties and low cost. XPS results after 15 minutes of sputtering identified black nickel as a Cermet mainly composed of two metallic nickel atoms for each nickel and zinc sulfide, i.e. 2 Ni: NiS: ZnS and traces of thiocyanate. The MFM black nickel lock-in-phase 1 x 1 ƒέm image presents a estimate mean diameter particle size in of (31 'Σ 16) nm and mode diameter particle size of (6 'Σ 16) nm. This nanometric particle was attributed to the ferromagnetic metallic nickel found in XPS analysis. Thus, MFM validate that black!
nickel solar absorber coating is a nanometric graded cermet of NiS-ZnS with 13 % of metallic nickel nanoparticles by chemical composition of XPS results and MFM.
