A CLUSTER PAIR: A3532 AND A3530

We present a detailed study of a close pair of clusters of galaxies, A3532 and A3530, and their environments. The Chandra X-ray image of A3532 reveals the presence of substructures on scales of ∼20″ in its core. XMM-Newton maps of the clusters show excess X-ray emission from an overlapping region between them. Spectrally determined projected temperature and entropy maps do not show any signs of cluster scale mergers either in the overlapping region or in any of the clusters. In A3532, however, some signs of the presence of galaxy scale mergers are visible, e.g., anisotropic temperature variations in the projected thermodynamic maps, a wide-angle-tailed (WAT) radio source in the brighter nucleus of its dumbbell brightest cluster galaxy, and a candidate X-ray cavity coincident with the northwestern extension of the WAT source in the low-frequency radio observations. The northwestern extension in A3532 seems either a part of the WAT or an unrelated diffuse source in A3532 or in the background. There is an indication that the cool core in A3532 has been disrupted by the central activity of the galactic nucleus. A reanalysis of the redshift data reinforces the close proximity of the clusters. The excess emission in the overlapping region appears to be a result of tidal interactions as the two clusters approach each other for the first time. However, we cannot rule out the possibility of the excess being due to the chance superposition of their X-ray halos.
Optimization models for design and operation of chemical batch processes

Batch and semi-batch processes are essential in the chemical processing industry. Products produced in batch plants range from simple agri¬ cultural chemicals to innovative, complex, high value pharmaceutical products. Batch processes can be readily scaled up from bench scale experimental data, designed from relatively modest engineering infor¬ mation and structured to handle multiple products whose individual production requirements are not large enough to justify the construc¬ tion of a dedicated plant. Batch processes also offer a higher degree of production flexibility. In this work the optimal preliminary grassroots design of a multi-product batch plant is addressed. In a multi-product plant several si¬ milar products are produced in the plant but usually only one product is produced at a time. This preliminary design problem arises when the physical steps in the product recipe are known and the different tasks, as defined by the recipe, are assigned to general purpose units. Now, a number of discrete decisions have to be made in order to determine an efficient design. The solution to the preliminary design problem that is obtained is intended to be a starting point for detailed mechanical design and actual plant layout. In this thesis a number of models for the preliminary design of a batch plant are presented. The objective of these models is to mini¬ mize the capital cost of the plant. The structural alternatives that are considered for the design are; parallel batch units, parallel semi-continuous equipment items and the possible insertion of intermediate storage tanks. The plant models, with their respective discrete decisions, are ex¬ pressed as Mixed-Integer NonLinear Programming problems (MINLP). The MINLP models are solved with an implementation of the Outer-Approximation (OA) algorithm in the modeling language GAMS (Ge-iii
Simple supercapacitor charging scheme of an electric vehicle on small-scale hardware simulator: a prototype development for education purpose

Supercapacitor is one of electrical energy sources that have faster charging-discharging times when compared to other power sources, such as battery and fuel cell. Therefore, it is often used as an additional power source in an electric vehicle. In this paper, a prototype of small-scale electric vehicle simulator (EVS) is built and a simple charging scheme of supercapacitor is used for education purpose. EVS is an electric vehicle prototype which can show the vehicle’s powertrain on small-scale configuration. Main components of this device are two direct current motors (DCMs) with a linked axis of rotation. Therefore one of them will be able to act as a generator. The supercapacitor charging scheme is employed by controlling the relays. The hardware experimental result shows that the averages of charging current are proportional to the maximum slope angle of the road profiles. This scheme is simple due to the EVS utility and it is useful for education purpose.
On Chamberlinian-Ricardian trade patterns with many industries

This note explores the determinants of trade patterns by extending a Chamberlinian-Ricardian monopolistic competition trade model to have a larger number of industries as did Dornbush, Fischer and Samuelson (1977). It will be shown that the degree of cross-country technical differences among industries plays an important role as a determinant of trade within each industry.
Predicting Equity Price with Corporate Action Events Using LSTM-RNN

Forecasting the stock price of a particular has been a difficult task for many analysts and researchers. In fact, investors are highly interested in the research area of stock price prediction. However, to improve the accuracy of forecasting a single stock price is a really challenging task; therefore in this paper, I propose a sequential learning model for prediction of a single stock price with corporate action event information and Macro-Economic indices using LTSM-RNN method. The results show that the proposed model is expected to be a promising method in the stock price prediction of a single stock with variables like corporate action and corporate publishing.
THEORIES OF ORDERS ON THE SET OF

It is shown that small fragments of the first-order theory of the subword order, the (partial) lexicographic path ordering on words, the homomorphism preorder, and the infix order are undecidable. This is in contrast to the decidability of the monadic second-order theory of the prefix order [M.O. Rabin, Trans. Amer. Math. Soc. , 1969] and of the theory of the total lexicographic path ordering [P. Narendran and M. Rusinowitch, Lect. Notes Artificial Intelligence, 2000] and, in case of the subword and the lexicographic path order, improves upon a result by Comon & Treinen [H. Comon and R. Treinen, Lect. Notes Comp. Sci., 1994]. Our proofs rely on the undecidability of the positive Σ1-theory of (N, +, ·) [Y. Matiyasevich, Hilbert’s Tenth Problem, 1993] and on Treinen’s technique [R. Treinen, J. Symbolic Comput. , 1992] that allows to reduce Post’s correspondence problem to logical theories. Mathematics Subject Classification. 03D35.
A COMPARISON BETWEEN "OLD AND NEW" FEATURE EXTRACTION AND MATCHING TECHNIQUES IN PHOTOGRAMMETRY

The development of new photogrammetric systems has changed the user demand. At present, the images acquired by Unmanned Aerial Vehicles (UAV) and Mobile Mapping Technologies (MMT) are far from the normal condition and they also still need to reach reliable results for bad-textured images. The interest point operators and image matching techniques that have traditionally used in Photogrammetry are unable to give good results for these applications. The algorithms that are used in Computer Vision (CV) community could instead assure good results, in terms of number of matched points. For this reason, a comparison analysis between the SIFT operator [1] and traditional photogrammetric feature extraction and matching techniques has been carried out. Many experimental tests on UAV aerial images and MMS terrestrial acquisitions with high geometric distortions (rotation, 3D viewpoint, scale) have been performed, in order to evaluate the reliability of SIFT for automatic homologous point extraction.
Caregivers satisfaction with care received by paediatric oncology patients admitted at the University Teaching Hospital-Lusaka Zambia

Background: Diagnosis of cancer is a traumatic event that does not only affect the diagnosed patients but also their caregivers. Supportive interventions are therefore essential for the caregivers to go through the cancer pathway and attain a sense of satisfaction for both medical and none medical services. Therefore evaluating the extent to which patients and their caregivers are satisfied with health services is clinically relevant as satisfied patients are more likely to comply with treatment, take an active role in their own care, continue using medical care services and stay under the care of a health provider. Methods: This was a descriptive cross-sectional study that investigated caregiver satisfaction with care received by paediatric oncology patients at the Paediatrics University Teaching Hospital, Lusaka-Zambia. Purposive sampling was used to select study participants and all caregivers who were available in the paediatric oncology ward at the time of data acquisition were selected resulting into a sample size of 50 caregivers. Data was collected using a structured interview schedule. Results: More than half 26 (52%) of the respondents were knowledgeable about cancer disease, 13 (26%) were partially knowledgeable with only 11 (22%) were not knowledgeable. Despite high knowledge levels, 19 (38%) did not know the cancer stage of their child. The majority 30 (60%) of patients had partial access to cancer treatment with only 3 (6%) who reported having full access to treatment. Concerning professional support, majority 47 (94%) received good or very good support from the staff while only 3 (6%) received poor support. When all the factors assumed to influence satisfaction were considered, 18 (36%) of the respondents were very satisfied, 19 (38%) were partially satisfied with only 13 (26%) who were not satisfied with care received. Of the five factors which were hypothesized to influence caregiver satisfaction, only professional support had a significant association with caregiver satisfaction with a p value of . 004. Conclusions: Only professional support had a significant association with caregiver satisfaction against all other factors hypothesized to influence satisfaction, implying that if appropriate profession support is given, caregivers are more likely to get satisfied with care and consequently comply with treatment.
Simulating spatial and temporal evolution of multiple wing cracks around faults in crystalline basement rocks

Fault zones are structurally highly spatially heterogeneous and hence extremely complex. Observations of fluid flow through fault zones over several scales show that this structural complexity is reflected in the hydrogeological properties of faults. Information on faults at depth is scarce, hence, it is highly valuable to understand the controls on spatial and temporal fault zone development. In this paper we increase our understanding of fault damage zone development in crystalline rocks by dynamically simulating the growth of single and multiple splay fractures produced from failure on a pre-existing fault. We present a new simulation model, MOPEDZ (Modeling Of Permeability Evolution in the Damage Zone surrounding faults), that simulates fault evolution through solution of Navier's equation with a combined Mohr-Coulomb and tensile failure criteria. Simulations suggest that location, frequency, mode of failure and orientation of splay fractures are significantly affected both by the orientation of the fault with respect to the maximum principal compressive stress and the conditions of differential stress. Model predictions compare well with published field outcrop data, confirming that this model produces realistic damage zone geometries.
The balance-of-payments constraint : from balanced trade to sustainable debt *

The balance-of-payments (BP) constraint on growth is usually associated with Thirlwall’s (1979) model, which imposes balanced trade as a necessary long-run constraint on open economies. According to Thirlwall’s law, international capital flows and interest payments balance out during long intervals of time so that, given a stable real exchange rate, the long-run growth rate of a small open economy is limited by the growth rate of its exports divided by the income elasticity of its imports. Independently on whether such an empirical law holds for some sufficiently long intervals of time, in practice open economies may take several years to show balanced trade and, in the meanwhile, capital flows and interest payments are an important part of the BP constraint. To deal with capital flows, Thirlwall and Hussain (1982) extended Thirlwall’s (1979) original model to allow trade deficits and showed how the growth rate of a small open economy may also be constrained by capital inflows in addition to trade factors. However, a particular characteristic of their extension is that ––––––––––
Title The Transposition of the European Information andConsultation Directive in Ireland

In this report we examine a range of employee information and consultation mechanisms in 15 organisations in the Republic of Ireland. The research was conducted specifically in relation to the European Employee Information and Consultation Directive. While we note that many managerial respondents identified a positive link between employee consultation and organisational performance, the efficacy and interpretations of how these mechanisms operate in practice differed quite substantially according to employees. The evidence suggests that regulations contained in the European Directive provide the opportunities for more effective employee voice systems and the platform to extend representational rights at workplace level.
1/f noise sources

This survey deals with 1/f noise in homogeneous semiconductor samples. A distinction is made between mobility noise and number noise. It is shown that there always is mobility noise with an /spl alpha/ value with a magnitude in the order of 10/sup -4/. Damaging the crystal has a strong influence on /spl alpha/, /spl alpha/ may increase by orders of magnitude. Some theoretical models are briefly discussed none of them can explain all experimental results. The /spl alpha/ values of several semiconductors are given. These values can be used in calculations of 1/f noise in devices. >
THE ROLE OF SATISFACTION IN MEDIATING TRUST, COMMITMENT AND LOYALTY RELATIONSHIP: AN INTERNAL MARKETING APPROACH TO A UNIVERSITY

Higher Educational institutions in Indonesia, including in Bandung, inspite ofbeing a social organization, it must be able to compete with the foreign higher educational Institutions. Internal Marketing approach is one way to analyze the strengths of Internal Resources owned by a service company. Based on the internal marketing approach, an important element in creating excellence is employees’ satisfaction since the employees’ satisfaction will cause customers’ satisfaction (Lewis, 1996:57). This study is examining the mediating role of satisfaction intrust and commitment relationships with loyalty in a University in Bandung. Sample size is 162 respondents whom taken by self-administered questionnaires from bureau academic staff of Parahyangan Catholic University. This research shows that satisfaction is still a major consideration that cause loyalty, since there is a fully mediating role of satisfaction in trust and loyalty relationship. It means that trust should be elaborated into satisfaction firstly before turn into loyalty. It means that a higher educational institutions in Bandung should developed employees’ satisfaction to survive in the borderless economic competition. The authors also make some recommendations, especially the recommendation that satisfaction is still an important factor in determining loyalty, It means that a higher educational institutions in Bandung should developed employees’ satisfaction to survive in the borderless economic competition. in addition, the authors also citesLigas (2003) to build a trust in an organization as another recommendation.
Scale-free gravitational collapse as the origin of ρ ∼ r -2 density profile - a possible role of turbulence in regulating gravitational collapse

Astrophysical systems, such as clumps that form star clusters share a density profile that is close to rho similar to r(-2). We prove analytically this density profile is the result of the scale-free nature of the gravitational collapse. Therefore, it should emerge in many different situations as long as gravity is dominating the evolution for a period that is comparable or longer than the free-fall time, and this does not necessarily imply an isothermal model, as many have previously believed. To describe the collapse process, we construct a model called the turbulence-regulated gravitational collapse model, where turbulence is sustained by accretion and dissipates in roughly a crossing time. We demonstrate that a rho similar to r(-2) profile emerges due to the scale-free nature the system. In this particular case, the rate of gravitational collapse is regulated by the rate at which turbulence dissipates the kinetic energy such that the infall speed can be 20-50 per cent of the free-fall speed (which also depends on the interpretation of the crossing time based on simulations of driven turbulence). These predictions are consistent with existing observations, which suggests that these clumps are in the stage of turbulence-regulated gravitational collapse. Our analysis provides a unified description of gravitational collapse in different environments.
Labor Cost Adjustment Working paper NBS

Building on a unique survey of how Slovak firms adjust wages and prices, this paper studies the reduction of labour costs in two forms: base wage cuts and alternative margins for labour cost reduction. Anecdotal evidence suggests that wage-cutting by firms occurs more frequently in Slovakia than in any other country and that the use of alternative margins for labour cost reduction is also quite prevalent in Slovakia. Regression results support the strong relationship between the use of alternative margins and wage rigidities. I find that the use of any alternative margin is on average 30% more likely in firms facing nominal wage rigidity that in firms with flexible wages. JEL classification: J30, J50, E24, C81
Title Efficiently mining δ-tolerance closed frequent subgraphs

The output of frequent pattern mining is a huge number of frequent patterns, which are very redundant, causing a serious problem in understandability. We focus on mining frequent subgraphs for which well-considered approaches to reduce the redundancy are limited because of the complex nature of graphs. Two known, standard solutions are closed and maximal frequent subgraphs, but closed frequent subgraphs are still redundant and maximal frequent subgraphs are too specific. A more promising solution is δ-tolerance closed frequent subgraphs, which decrease monotonically in δ, being equal to maximal frequent subgraphs and closed frequent subgraphs for δ=0 and 1, respectively. However, the current algorithm for mining δ-tolerance closed frequent subgraphs is a naive, two-step approach in which frequent subgraphs are all enumerated and then sifted according to δ-tolerance closedness. We propose an efficient algorithm based on the idea of “reverse-search” by which the completeness of enumeration is guaranteed and for which new pruning conditions are incorporated. We empirically demonstrate that our approach significantly reduced the amount of real computation time of two compared algorithms for mining δ-tolerance closed frequent subgraphs, being pronounced more for practical settings.
An Integrated Model using Artificial Neural Network (ANN) and Kriging for Forecasting Air Pollutants using Meteorological Data

2 Abstract: Forecasting of air pollutants is an important area of research in view of the current concerns regarding environment. In particular, air quality is deteriorating due to emissions increasing, particularly in urban locations. In view of the health hazards posed by increasing air pollution, it will be useful to have a model that can predict the level of atmospheric pollutants and a geospatial interpolation approach to forecast the air pollutants over the whole domain. This paper presents an integrated model using Artificial Neural Networks and Kriging to predict the level of air pollutants at various locations in Mumbai and Navi Mumbai using past data available from meteorological department and Pollution Control Board. The proposed model is implemented and tested using MATLAB for ANN an R for Kriging and the results are presented.
Böhm-Bawerk meets Keynes: What does determine the interest rate, and can the latter become negative?

100 years after Bohm-Bawerks death and nearly 70 years after Keynes has died there is still fundamental controversy about the factors which determine the interest rate in the long run. While Economists in the Austrian tradition see it as solely driven by real phenomena, Keynesian authors mainly stress the monetary factors. Likewise, the current phase of low interest rates is explained in most different ways by prominent economists. While many blame the expansive monetary policy, others point to excess capital supply in ageing industrial states. The present paper seeks to combine these explanations by the use of a stock-flow-consistent macro-model. It is argued that theories in the tradition of Bohm-Bawerk and Keynes respectively do not at all preclude each other but, on the contrary, can nicely be combined.
Identifying the Determinants of Customer Retention in a Developing Country Context

This article investigates how image, perceived service quality and satisfaction determine customer retention in the retail banking industry in Malaysia. Data was obtained using a self-administered survey involving a convenience sample of 134 retail banking customers in Malaysia. The results show that image is both directly and indirectly related to retention through satisfaction while perceived service quality is indirectly related to retention through satisfaction. The article concludes that satisfaction is not the sole determinant of retention in retail banking. Some managerial implications of this research find that the interrelationships between the determinants (image, quality and satisfaction) allow bank managers to better understand the dynamics of customer retention formation
Sources of enterprise value

The value of the enterprise has an increased importance in business valuation, so maximizing it becomes a priority for the interested parties, such as its shareholders or investors. The purpose of this article is the analysis of the sources of enterprise value and its factors, in order to understand the causes of the decrease or the possibilities for maximizing the enterprise value, passing over the main concepts in the literature. The analysis refers to the listed companies on the Bucharest Stock Exchange (BVB) from the energy sector, including the largest Romanian company as per its capitalization, OMV Petrom. The research took into account the fact that the analysis of a large company with a long history is facilitated by the existence of multi-annual information, unlike the firms in the early life cycle operating in an emerging market.
