INFLUENCE OF TEMPERATURE DIFFERENCES OF MIXED STREAMS UPON T-JUNCTION DAMAGE

The problem of thermal fatigue in pipe connections under the influence of streams mixing is one of the most discussed problems on international conferences. Numerous failures occur in industry as a result of this damage mechanism. It is caused by frequent stress changes developed by an effect of non-stationary thermal fields. The degree of damage is greatly dependent on characteristic of material, geometrical design of a pipe connection in operational conditions. The report is dealing with influence of temperature differences of mixing media streams upon pipe material damage cumulation. It is focused on a perpendicular T-junction made of ferritic steel, which is protected inside with an anticorrosive weld deposit from austenitic steel. Six cases of temperature differences will be considered for particular operational conditions with a step of 50 °C, and the damage cumulation process will be observed. Thanks to it, it will be possible to judge better the meaning of streams temperature differences.
MODELING OF PLANAR METAMATERIAL STRUCTURE AND ITS EFFECTIVE PARAMETER EXTRACTION

This paper is about designing a Metamaterial structure and the Scattering Parameter Extraction Method that has become a prime tool for Metamaterial characterization so that there is a better understanding of relation between their configuration and associated properties of these materials in terms of negative permittivity and negative permeability to explore application potential. A 2D planar Metamaterial structure has been designed, fabricated and analyzed. It consists of conducting patches and meander lines on a dielectric substrate. Electromagnetic modeling was carried out using Finite Difference Time Domain method based simulation tool EMPIRE XCcel. The simulated reflection and transmission coefficients for the proposed metamaterial structure indicate the stopband at 5.5 – 12 GHz. The fabricated Metamaterial structure was analyzed using Network Analyzer verifying that material is Doubly Negative in nature.
Charge symmetry breaking in A = 4 hypernuclei

Charge symmetry breaking in the A = 4 hypernuclear system is reviewed. The data on binding energies of the mirror nuclei and hypernuclei are examined. At the Mainz Microtron MAMI the high-resolution spectroscopy of decay-pions in strangeness electro-production is used to extract the Λ hyperon ground state binding energy in 4 Λ H. This binding energy is used together with the 4 Λ He ground state binding energy from nuclear emulsion experiments and with energy levels of the 1 + excited state for both hypernuclei from γ-ray spectroscopy to address the charge symmetry breaking in the strong interaction. The binding energy difference of the ground states in the mirror pair is reduced from its long accepted value Δ B 4 Λ (0 + g.s. ) ≈ 0.35MeV to ≈ 0.24MeV. The energy difference of the excited states becomes Δ B 4 Λ (1 + exc ) ≈ −0.08MeV, for the first time with opposite sign. These values were not reproduced by theoretical calculations with the exception of very recent approaches, although with a large systematic dependence. The full understanding of the charge symmetry breaking in the A = 4 hypernuclei still remains one of the open issues of hypernuclear physics.
A NOTE ON ARÉVALO-TOMÉ AND CHAMORRO-RIVAS: LOCATION AS AN INSTRUMENT FOR SOCIAL WELFARE IMPROVEMENT IN A SPATIAL MODEL OF COURNOT COMPETITION

In a recent paper in this journal, Arevalo-Tome and Chamorro-Rivas claim to have shown that, in a two-stage game where Cournot duopoly firms discriminate over two marketplaces on a line, a social planner can use the firm’s location variable as an instrument for reallocating production from the equilibrium spatial pattern to the optimal outcome. This note points out that with linear demand there is no need to use such an instrument for social welfare improvement, because the equilibrium locations are indeed socially optimal. The note also discusses the possibility of using such an instrument for general demand.
Role of Leadership Styles and Self Efficacy on Employeesâ Job Involvement in Enugu State

The study investigated the role of leadership styles and self efficacy on employees’ job involvement. Two hundred and eighty participants took part in the study. Three instruments were used for data collection. They were Leadership Behavior Description Questionnaire (LBDQ), Self-efficacy Scale (SES) and Job Involvement Scale (JIS). Two hypotheses were tested. Two-way analysis of variance (ANOVA) was used to analyze the data. Result shows that there is a significant difference between different types of leadership styles on job involvement as well as self efficacy and job involvement. The results were discussed in terms of their relevance in work setting and suggestions for further research made.
Computing method of ray intercept in radio wave tunnel perspective technology

Ray intercept algorithm is the key factor to improve the speed of radio tomography. A second scan search algorithm is proposed to acquire the intersecting point coordinates between ray and gridlines. For this algorithm , successive scanning and sorting of intersection sequence would consume much computing time and memory. In order to avoid successive scanning, search variables have been introduced into search procedure to reduced scan range. Search progress has been improved to omit the sort process at the same time. Through these two improvements, the number of searches has been greatly reduced. The algorithm proposed in this paper is proved to be effective and accurate by electromagnetic wave amplitude tomography inversion calculation of a certain coal face fault structure perspective data. Keywords—radio wave tunnel perspective; computed tomography; ray intercept; search variables
A Neural Network Classifier for Spectral Pattern Recognition

In this contributon we evaluate on-line and o -line techniques to train a single hidden layer neural network classi er with logistic hidden and softmax output transfer functions on a multispectral pixel-by-pixel classi cation problem. In contrast to current practice a multiple class cross-entropy error function has been chosen as the function to be minimized. The non-linear di erential equations cannot be solved in closed form. To solve for a set of locally minimizing parameters we use the gradient descent technique for parameter updating based upon the backpropagation technique for evaluating the partial derivatives of the error function with respect to the parameter weights. Empirical evidence shows that on-line and epoch-based gradient descent backpropagation fail to converge within 100,000 iterations, due to the xed step size. Batch gradient descent backpropagation training is superior in terms of learning speed and convergence behaviour. Stochastic epoch-based training tends to be slightly more e ective than on-line and batch training in terms of generalization performance, especially when the number of training examples is larger. Moreover, it is less prone to fall into local minima than on-line and batch modes of operation.
Determinants of the Optimal Network Configuration and the Implications for Coordination

This paper develops a simulation model to compare the performance of two stylized manufacturing networks: the lead factory network (LFN) and the archetype network (AN). The model identifies the optimal network configuration and its implications for coordination mechanisms. Using an NK simulation model to differentiate between exogenous factors (configuration) and endogenous factors (coordination), we find low complexity of the production process, low transfer costs and high search costs, as well as a larger number of manufacturing plants benefit LFN compared to AN. Optimally coordinating the chosen network configuration of LFN might require to fully transfer knowledge in the short run but to transfer nothing in the long run. Moreover, a late knowledge transfer from the lead factory to the plants increases the pre-transfer performance of LFN but results in a larger performance drop, yielding a lower short-run but a higher long-run performance of LFN.
THE IMPACT OF BANKING DEREGULATION ON CANADIAN BANKS RETURNS

This paper revisits the impact of OBS activities on Canadian banks risk-return trade-off. Recent studies (Stiroh and Rumble 2006, Calmes and Liu 2007) suggest that increasing OBS activities do not necessarily yield straightforward diversification benefits. However, adding a risk premium to earlier accounting returns models by resorting to an ARCH-M procedure, an updated sample reveals that the Canadian banks risk-return trade-off displays a structural break, around 1997. In the second subperiod (1997-2007) of our sample, we find that the share of noninterest income no longer negatively impacts banks returns. Relatedly, we find that a risk premium emerges while, in the first period (1988-1996), the volatility variable is not significant in any returns equations. Our results are thus consistent with a maturation process story.
Automatic Tagging of Process Type

This paper discusses the construction of an application for the automatic classification of process types, based on Systemic Functional Linguistics (SFL). The application, which was constructed using WordNet, SUMO and FrameNet, when combined with an available part-of-speech tagger, links each verb with its corresponding process type. This application should provide helpful information which can contribute to improving efforts at achieving automatic summarization.
OWNERSHIP STRUCTURE AND RISK DISCLOSURE: A STUDY OF MALAYSIAN LISTED COMPANIES

This research focuses on the importance of ownership structure as a determinant of risk disclosure. It is expected to contribute to the literature particularly in the Malaysian context, where risk disclosure practice is in the infancy stage. This study uses multiple regressions in assessing the variability of the extent of risk disclosure. The overall results confirm that highly concentrated ownership would lead to high agency problem, which then leads to less disclosure. This implies that, to promote greater transparency in countries where many of the large listed companies are family-owned, more stringent laws that mandates adequate risk disclosure is clearly warranted. This would ensure that the needs of all stakeholders are properly met.
Antibacterial activity and preliminary screening of phytochemicals of whole plant of Enicostemma littorale.

Enicostemma littorale is a glabrous perennial herb belonging to the family Gentianaceae. The whole plant is used in traditional medicine for the treatment of various diseases. The decoction is used to treat skin diseases such as kiranthi, itching and scabies. Phytochemical screening was carried out to identify the active functional groups of E. littorale plant which revealed the presence of alkaloids, saponins, steroids, flavonoids, glycosides and triterpenoids. Antibacterial activity of the aqueous extract of the whole plant of E. littorale on eight bacterial isolates was investigated. They were Staphylococcus aureus - NCTC 6571, Escherichia coli - NCTC -10418, Pseudomonas aeruginosa - NCTC - 10662 and five wild strains of Methicillin resistant Staphylococcus aureus (MRSA). Antibacterial activity was performed by the cut well diffusion and agar dilution methods. The aqueous extract of E. littorale showed growth inhibitory action against S. aureus (NCTC 6571 and 5 MRSA strains). Growth inhibitory action against E. coli and P aeruginosa could not be demonstrated using the agar dilution method, although inhibition of E. coli was shown using the cut well method. Further exploration of activity of the aqueous extract against a wider range of skin pathogens would be helpful. The ability of the aqueous extract of E. littorale to inhibit the growth of bacteria is an indication of its antibacterial potential which may be employed in the management of bacterial infections.
The Role of Social Presence in Cross-Border e-Commerce Accounts on Commitment

While online shopping websites are facing the difficulties of price and low-quality competition, cross-border online shopping is on a vigorous development trend, showing that cross-border shopping is an important trend of online shopping field. To provide a deeper understanding of how cross-border e-commerce accounts can effectively engage consumer, this study examines the social aspects of the cross-border e-commerce context by focusing on social presence. The aim of this study is to provide the development marketing strategy and product positioning in the future. This study investigates the relationships among satisfaction, trust, social presence, affective commitment and calculative commitment. Though an experiment with 908 Ali express users, the study finds that all hypotheses are supported. Social presence is formed through emotion value, social value, and monetary value; that greater social presence increases users’ satisfaction and their trust in the company. The findings indicate the differential influence of various antecedents on affective and calculative commitment, and highlight the role played by these forms of commitment on consumption satisfaction and trust. The results demonstrate the importance of affective commitment as a relationship enhancer, and identify managerial implications for customer commitment to cross-border e-commerce accounts.
COMPLEMENTARITY OF HISTORIC BUILDING INFORMATION MODELLING AND GEOGRAPHIC INFORMATION SYSTEMS

Abstract. In this paper, we discuss the potential of integrating both semantically rich models from Building Information Modelling (BIM) and Geographical Information Systems (GIS) to build the detailed 3D historic model. BIM contributes to the creation of a digital representation having all physical and functional building characteristics in several dimensions, as e.g. XYZ (3D), time and non-architectural information that are necessary for construction and management of buildings. GIS has potential in handling and managing spatial data especially exploring spatial relationships and is widely used in urban modelling. However, when considering heritage modelling, the specificity of irregular historical components makes it problematic to create the enriched model according to its complex architectural elements obtained from point clouds. Therefore, some open issues limiting the historic building 3D modelling will be discussed in this paper: how to deal with the complex elements composing historic buildings in BIM and GIS environment, how to build the enriched historic model, and why to construct different levels of details? By solving these problems, conceptualization, documentation and analysis of enriched Historic Building Information Modelling are developed and compared to traditional 3D models aimed primarily for visualization.

Effects of Self-Efficacy on Individual Earnings: A Preliminary Study of the Thai Labor Market

This study estimates the earnings differences in the Thai labor market that are related to workers’ non-cognitive skills by examining the psychological characteristic of self-efficacy. Self-efficacy is defined as a person’s belief in his or her ability to organize and execute courses of action necessary to achieve a goal. The Thai Mental Health Survey measures both basic socio-economic factors and two psychological indicators of self-efficacy and affective state, drawn from 15 items of the Thai Mental Health Indicator. The effect of self-efficacy on an individual’s annual earnings is estimated using both OLS and IV techniques. From the selected sample, the study confirms that the Thai labor market values self-efficacy, even though it is endogenous. Self-efficacy is independent of gender, religion and marital status, and its effect on earnings is unrelated to years of schooling or work experience. Omitting self-efficacy from the model results in underestimation of female earnings, underestimation of earnings in occupations, and overestimation of earnings in the countryside. Self-efficacy likely contributes to additional earnings (such as earnings from overtime and bonuses) made through intense effort, compared with traditional human capital of schooling or work experience. Policy recommendations aimed at improving self-efficacy and areas for further studies are suggested.
COMPARISON OF VISUAL ASSESSMENT AND POLYMERASE CHAIN REACTION ASSAY TESTING TO ESTIMATE THE INCIDENCE OF THE HUANGLONGBING PATHOGEN IN COMMERCIAL FLORIDA CITRUS

Huanglongbing (HLB = citrus greening) is one of the most serious diseases of citrus worldwide. The disease is caused by species of bacteria in the genus Candidatus Liberi- bacter and was discovered for the first time in the United States in Florida in August, 2005. To date, the Asian form of HLB, caused by Candidatus Liberibacter asiaticus, is the only form of HLB that has been found in Florida. Molecular detec- tion protocols are available for the detection of HLB but due to the uneven distribution of the bacterium in trees, the serolog- ical variability of the pathogen, and perceived limitations of testing methodology, molecular testing generally has been limited to the confirmation of visible infections and not for de- tection of infections in non-symptomatic plants. In this study, visual surveys were compared to the testing of trees with a real-time polymerase chain reaction-based assay (real-time PCR). The incidence of infection based on real-time PCR test- ing may be up to two times the incidence of infection estimat- ed by visible symptoms alone.
Patient Preparation for Oncological FDG-PET/CT Imaging

Özet Pozitron emisyon tomografisi (PET)/bilgisayarlı tomografi (BT) çekimine giren onkoloji hastalarında tümör metabolizması hakkında nicel ve nitel veri elde etmek için radyoaktif olarak işaretlenmiş [18F]-2-floro-2-deoksi-Dglukoz (FDG) kullanılır. FDG-PET/BT görüntüleme (tarama) öncesi hasta hazırlığı süreci esas olarak, hasta bilgilerinin elde edilmesini, görüntüleme öncesi aç kalınmasını, kan şekeri ve insülin seviyelerinin düzenlenmesini, hastaya FDGradyolojik kontrast maddeler ve yardımcı ajanların verilmesini, yeni tedavi almış hastalarda görüntülemenin ne zaman yapılacağının planlanmasını, gebelik ve emzirme dönemindeki görüntülemeyi ve görüntüleme öncesi son düzenlemeleri içerir. Onkolojik FDG-PET/BT görüntülemede hasta hazırlığı işlemlerinin standardize edilmesi, yüksek kalitede görüntülerin elde edilmesi, yalancı negatif-yalancı pozitif bulguların azaltılması ve hastanın aldığı radyasyon dozunun olabildiğince düşürülmesi için son derece önemlidir.
Electrostatic and Hydrophobic Interactions in NaCMC Aqueous Solutions: Effect of Degree of Substitution

The rheology of water-soluble polyelectrolytes at intermediate and high concentrations is controlled by entanglement, hydrophobic, and electrostatic interactions, whose influences are difficult to isolate. We investigate the rheology of semidilute solutions of sodium carboxymethyl cellulose (NaCMC) with molecular weight Mw ≃ 2.5 × 105 g/mol and varying degree of substitution (DS) as a function of polymer concentration in various solvent media: salt-free water (long-ranged electrostatic interactions), 0.5 M aqueous NaCl (screened electrostatics), and 0.5 M aqueous NaOH (screened electrostatics, diminished hydrophobic interactions) in order to selectively examine the role played by these different interactions. Decreasing DS is found to decrease solubility and induce partial aggregation and eventual gelation. In salt-free and 0.5 M NaCl solution, NaCMC with DS ≃ 1.2 exhibits hydrophilic polyelectrolyte and neutral polymer in good solvent behavior, respectively. Decreasing DS to ≃0.7–0.8 leads to hydrophobic.
STUDY ON THE INTERACTION BETWEEN THE FOOD AND BEVERAGE SERVICESCAPE AND CUSTOMER WAITING

Past research on the customer waiting experience tended to focus on two primary areas, namely managing the wait and managing the perception of the wait. Very few studies conducted in-depth analysis and discussion of how external environmental factors affect the experience of customer waiting, which it was also viewed as a negative factor that decreases customer satisfaction toward service. However, in reality, the waiting experience can be positive as a result of certain environmental factors, and subsequently increases customer satisfaction toward the service. This study aimed to further examine the potential influencing factors arising from the servicescape during the customer waiting process, and the interaction between the servicescape and customers during their wait time. This paper is based on the causal feedback loop. A system dynamics perspective was applied to construct a conceptual systems model showing the interaction between the servicescape and the customer waiting experience. KeYwords Critical Incident Technique (CIT); Dramaturgy theory; Servicescape; System dynamics; Waiting experience. resumen Los estudios previos sobre la experiencia de espera de los clients suelen centrarse sobre todo en dos áreas: la gestión de la espera y la gestión de la experiencia de espera. Existen muy pocos estudios que hayan realizado análisis y discusiones en profundidad sobre cómo los factores ambientales externos afectan a la experiencia de espera de los clientes, que se ha considerado siempre como un factor negativo que reduce la satisfacción del cliente hacia el servicio. Sin embargo, la experiencia de espera puede incrementar en realidad la satisfacción del cliente hacia el servicio. Este estudio pretende profundizar en la influencia potencial de los factores que surgen del “servicescape” durante el proceso de espera del cliente, así como la interacción entre el “servicescape” y los clientes durante el tiempo de espera. Ese artículo se basa en el bucle de retroalimentación causal. Desde la perspectiva de la dinámica de sistemas se construye un modelo de sistemas conceptuales que muestra la interacción entre el “servicescape” y el cliente en la experiencia de espera.

Void Prediction During Liquid Composite Molding Processes: Wetting and Capillary Phenomena

The aim of this work is to contribute in improving fibrous preforms impregnation for Liquid Composite Molding (LCM) processes. The void prediction in LCM sparks off interest within the Composite Material elaboration because it represents a significant issue to keep the expected mechanical properties of the final product. The liquid properties, the preform geometry and the flow conditions impact the void or bubble entrapped inside and outside the yarns. Nevertheless, due to the complex geometry of the reinforcement, experimental characterization of bubble formation remains delicate. Thus, our study deals with two simple model networks representing connected pores so called "Pore Doublet Model". A first is considering two capillaries converging on a node (T-junction) and a second is representing two capillaries interconnected with a supplying principle. In this paper, we emphasize on microfluidic and millifluidic approaches where wetting and capillary forces are significant during bubble formation mechanism.
