B. – Dr. Sc. , Professor, Head of the Department of Software of Automated Systems, Admiral Makarov National University of Shipbuilding, Mykolaiv, Ukraine. ABSTRACT Context. The problem of estimating the software size in the early stage of a software project is important, since the information obtained from estimating the software size is used for predicting the software development effort, including open-source Java-based information systems. The object of the study is the process of estimating the software size of open-source Java-based information systems. The subject of the study is the regression models for estimating the software size of open-source Java-based information systems. Objective. The goal of the work is the creation of the non-linear regression model for estimating the software size of open-source Java-based information systems on the basis of the Johnson multivariate normalizing transformation. Method. The model, confidence and prediction intervals of multiply non-linear regression for estimating the software size of open-source Java-based information systems are constructed on the basis of the Johnson multivariate normalizing transformation for non-Gaussian data with the help of appropriate techniques. The techniques to build the models, equations, confidence and prediction intervals of non-linear regressions are based on the multiple non-linear regression analysis using the multivariate normalizing transformations. The appropriate techniques are considered. The techniques allow to take into account the correlation between random variables in the case of normalization of multivariate non-Gaussian data. In general, this leads to a reduction of the mean magnitude of relative error, the widths of the confidence and prediction intervals in comparison with the linear models or nonlinear models constructed using univariate normalizing transformations. Results. Comparison of the constructed model with the linear model and non-linear regression models based on the decimal logarithm and the Johnson univariate transformation has been performed. Conclusions. The non-linear regression model to estimate the software size of open-source Java-based information systems is constructed on the basis of the Johnson multivariate transformation for B S family. This model, in comparison with other regression models (both linear and non-linear), has a larger multiple coefficient of determination, a larger value of percentage of prediction and a smaller value of the mean magnitude of relative error. The prospects for further research may include the application of other multivariate normalizing transformations and data sets to construct the non-linear regression model for estimating the software size of open-source Java-based information systems.
Analyzing long-term evapotranspiration of Lake Fenéki wetland ( Kis-Balaton , Hungary ) between 1970 and 2012

The aim of the study was to estimate long term evapotranspiration (ET) of Kis-Balaton wetland through the investigation of Lake Fenéki. Data set was processed using the West-transdanubian Water Inspectorate methodology. Potential evapotranspiration (PET) was calculated using Hungarian empirical models (Antal and Dunay), while Lake Fertő formula was applied evaluating the ET that includes the impacts of vegetation. Calculated PET values of the wider (adjacent) environment of Lake Fenéki (Zalaegerszeg, Nagykanizsa, and Keszthely meteorological stations) differed significantly and further variation was observed in PET, when measured meteorological elements on Lake Fenéki were applied. PET increment, as a result of linear trend fitted to the 43-year long data (Keszthely station) was 3–4 mm year. Relation between PET calculated from the data of Keszthely station and for Lake Fenéki was strong, so PET of Lake Fenéki can be originated from the data of Keszthely station. Calculated ET was not significantly different due to the likely similar input data in ET calculation model of Hungarian Meteorological Service (OMSZ). 43-year annual mean ET for Lake Fenéki was 809±88 mm. This ET was 84% of calculated PET. Analyzing the nine dry-warm seasons, average annual ET exceeded the long term average (874.7±37.6 mm) with 78 mm. The average ET of the remaining 34 wet-cold seasons totalled 796.6±89.4 mm. Empirical formulas cannot be replaced, according to monthly ET comparisons, by using “A” class pan estimating the ET of aquatic habitats. Seasonal pattern of monthly ET time series for Lake Fenéki was analyzed using autoregressive integrated moving averages (ARIMA) modeling technique. After first differencing, the transformed series was stationary and found to be governed by moving average process of order 1. Key-words: wetland evaporation, potential evapotranspiration, seasonal ARIMA, KisBalaton wetland (Lake Fenéki)
A REVIEW OF THE SKILL SHORTAGE CHALLENGE IN CONSTRUCTION INDUSTRY IN SRI LANKA

Construction companies of Sri Lanka voice on a prevailing skill shortage of the country. Therefore, the purpose of this review is to investigate the concept of skill shortage, causal factors, and mitigation measures relevant to Sri Lanka construction context using already available secondary data. Recommended steps for a Systematic Literature Review have been followed. Findings show that there are three issues in the industry: shortage of people, skill mismatch and skill deficiency. Mainly there are shortages of people in construction industry of Sri Lanka in the categories of unskilled workers (laborers), craftsmen and construction machine operators and experienced construction professionals. This review identifies sixteen possible causal factors for skill shortage and sixteen mitigation measures. Skill shortages are often seen as a problem of the education system of the country. But this review suggest to have a much broader perspective on the issue of skill shortage and emphasize that there is a serious problem of attracting, training and retaining of people in the construction industry of Sri Lanka. Findings will be instrumental for policy makers, practitioners and also future researchers can use this as a good base for further studies.

5 PARALLEL CO-VOLUME SUBJECTIVE SURFACE METHOD FOR 3 D MEDICAL IMAGE SEGMENTATION

In this chapter we present a parallel computational method for 3D image segmentation. It is based on a three-dimensional semi-implicit complementary volume numerical scheme for solving the Riemannian mean curvature flow of graphs called the subjective surface method. The parallel method is introduced for massively parallel processor (MPP) architecture using the message passing interface (MPI) standard, so it is suitable, e.g., for clusters of Linux computers. The scheme is applied to segmentation of 3D echocardiographic images.

N IH -P A A uhor M anscript N IH -P A A uhor M anscript N IH -P A A uhor M anscript conducted a phase I/II trial of daclizumab in 34 patients with ATL. Saturation of surface CD25 on circulating ATL cells was achieved at all doses; however saturation on ATL cells in lymph nodes required 8 mg/kg. Up to 8 mg/kg of daclizumab administered every 3 weeks was well tolerated. No responses were observed in 18 patients with acute or lymphoma ATL; however, 6 partial responses were observed in 16 chronic and smoldering ATL patients. The pharmacokinetics / pharmacodynamics of daclizumab suggest that high-dose daclizumab would be more effective than low-dose daclizumab in treatment of lymphoid malignancies and autoimmune diseases (e.g., multiple sclerosis) since high-dose daclizumab is required to saturate IL-2R alpha in extravascular sites.
Investigating the effectiveness of team communication and the balance of member contributions on knowledge acquisition

Abstract This study aims to explore the effect of project team communication and the balance of member contributions on knowledge management, specifically in the case of knowledge acquisition by project managers when multiple projects are being managed within the oil and gas industry. The study uses the quantitative research method and a survey questionnaire that targeted multiple-project managers to collect the data utilised in the testing of the research hypotheses. The multiple regression approach was used to analyse the collected data. A total of 184 multiple-project managers participated in this study. The results show that both communication and the balance of member contributions have significant positive impacts on knowledge acquisition in a multiple-project management setting. The findings of this study facilitate a holistic understanding of project team collaboration through two factors, i.e., “communication” and “balance of member contributions”, which influence knowledge acquisition by project managers within organisations. This understanding will improve the effectiveness of the knowledge management (KM) process and increase project manager efficiency.
A TEST OF SEPARABILITY AND RANDOM EFFECTS IN PRODUCTION FUNCTION WITH DECOMPOSED IT CAPITAL H6@ K. PND

In productivity analysis, many studies have used real value-added function for estimating productivity. These studies have made explicit or implicit assumption that real value-added function exists. As real value-added is the residual of real gross output from real intermediate input through the double deflation method, the existence of real value-added function is not guaranteed automatically. In order to test this, we have used an additively strong separability test. We could not accept the existence of real value-added function from the data of 32 industries during the period of 1981-2002 in Korea. This means that it is more appropriate to use gross output based productivity rather than value-added based one. In addition, in order to identify the contribution of IT investments, we have decomposed capital stock into IT capital stock and non-IT capital stock. We have failed to find the evidence that IT capital has increased productivity in the entire economy which supports the Solow (1987) paradox. However, when we decomposed the industries by IT capital intensity, there is a significant contribution of IT capital to gross output in the highly IT capital intensive industries. This phenomenon is related to the substitution elasticity between IT capital and non-IT capital.
Influence of diet on life table and population growth parameters of predatory mite Neoseiulus barkeri ( Hughes ) ( Acari : Phytoseiidae )

The predatory mite Neoseiulus barkeri (Hughes) is the most important and wide distributed phytoseiid mite. This predatory mite fed on plant injurious mite and small insect pests. Neoseiulus barkeri has been collected from cucumber infested with twospotted spider mite. Life tables of this predatory mite were studied on onion thrips (Thrips tabaci Lind (Thysanoptera: Thripidae)), two-spotted spider mite (Tetranychus urticae Koch (Acari: Tetranychidae)) and corn pollen, first larvae of onion thrips and egg mites were used as prey. This research was investigated in the laboratory by using the mulbery excised leaf method in petri dishes at 27± 1 ̊C, 16L: 8D photoperiod and 70-80% RH. Data were analyzed based on the agestage, twosex life table theory. Adult longevity (male) on three diets did not show any significant difference, but adult longevity (female) on corn pollen were significantly shorter than those reared on T. tabaci and T. urticae. Preimaginal developmental time showed a significant difference in the mentuioned treatments. The lifetime fecundities were 23.58, 48.67 and 26.40 offspring on T. tabaci, T. urticae and corn pollen respectively. The intrinsic rate of increase (rm) on T. tabaci, T. urticae and corn pollen were 0.162d -1 , 0.171 d -1 and 0.103 d -1 respectively and show a significant difference. Net reproduction rate (R0) and Finite rate of increase (λ) on three diets were not different. The mean generation time on T. tabaci, T. urticae and corn pollen showed a significant difference. With attention to observed results, N. barkeri is a general predator and can play an important role in the biological control of T. urticae and T. tabaci. Corn pollen was suitable alternative food for this predator.
Effects of Physical Exercise with and without Pomegranate Concentrate Consumption on the HbA 1 c and C-peptide Levels in the Middle-aged Women with Metabolic Syndrome

Article type: Research Paper Introduction: Metabolic syndrome is defined as a cluster of metabolic disorders, which may lead to type II diabetes and cardiovascular diseases. Promotion of healthy lifestyle and use of herbal supplements with anthocyanin and phenols are recommended for the treatment of metabolic syndrome. The present study aimed to investigate the effects of eight weeks of combined aerobic and resistance exercises and pomegranate concentrate consumption on the levels of HbA1c and Cpeptide in women with metabolic syndrome. Methods: This study was conducted on 30 middle-aged women with metabolic syndrome, who were randomly assigned to two groups of exercise (E; n=15) and exercise with pomegranate concentrate (EPC; n=15). The exercise protocol was conducted at 60-80% intensity of the maximal heart rate and 60-80% of one-repetition maximum. Data analysis was performed in SPSS version 20 at the significance level of P≤0.05. Results: HbA1C levels significantly reduced in the EPC group (P<0.05), while no significant difference was observed between the groups in terms of the C-peptide and HbA1C levels (P>0.05). In addition, the within-group comparison indicated no significant changes in the C-peptide levels in the E and EPC groups (P>0.05). Conclusion: According to the results, regular physical exercises along with the consumption of pomegranate concentrate could be effective in reducing HBA1c. Improving a number of metabolic syndrome indices (e.g., insulin resistance) could prevent the complications of metabolic syndrome in middle-aged women.

IMAGE REGISTRATION: EVALUATION AND COMPARISON OF NON-RIGID TRANSFORMATION ALGORITHMS

Image registration is a technique, which helps in comparing and combining two images, which are taken at same or different times, with same or different cameras. The resultant image, which is obtained after the combination, is useful for the analysts as it gives complete information in one image, which is earlier in two different images. For doing image registration one can use feature-based methods or similarity measures can be used for the optimization purpose. In this paper feature based and intensity based registration methods are compared using various transformation functions. The results clearly showed that geometric based measures outperformed intensity based transformations in terms of execution time. In addition, Global transformations outperformed local transformations in terms of execution time
An extension of a visualization component of ontology based portals with visual analytics facilities

The process of development of an ontology-based knowledge portal and creation of its content is time-consuming and laborious. The lifetime of such portals is sufficiently long and they collect a great volume of valuable information. This information can be analyzed from various points of view. This paper describes an extension of the visualization subsystem, developed the A.P. Ershov Institute of Informatics Systems, with new tools for visual analysis. An example of extracting information about scientific cooperation from the content of a knowledge portal and two ways of its visualization are demonstrated.
Improving Performance and Interoperability of the ESTRACK Planning System

The ESTRACK Planning System (EPS) is a fully integrated planning system dedicated to the automated centralized allocation of ground station services to space missions. The EPS is operationally used at the European Space Operations Centre in Darmstadt, Germany. Instead of assigning a ground station statically to a mission, the EPS identifies ground stations which can provide the required services at the required times to a mission and plans the ground station allocation for all participating missions. The produced plans are stored in the ESTRACK Management Plan (EMP), which consists of a set of booking periods of the ground stations by the missions with the associated required services. This booking evolves as the event timings are updated and as more and more missions are taken into account. The EMP is then used by the ESTRACK Scheduling System (ESS) to generate executable ground station schedules. Since its operational introduction, the EPS has been extended by a range of new features improving its performance and interoperability. Such new features as dynamic resource profiling, interchangeable planning strategies and plan stabilization are already now used operationally. A number of further features, such as medium term planning (plan ranges up to one year), long term load analysis, system aided plan refinement, interchangeable optimization criterion and requirement relaxation, are currently under development.
5 Peptide Emergence , Evolution and Selection on the Primitive Earth II . The Primary Pump Scenario

We propose a dynamic scenario for the emergence and evolution of peptides on the primitive Earth, through a molecular engine (the primary pump), which works at ambient temperature and continuously generates, elongates and complexifies sequential peptides. This new scenario is based on a cyclic chemical reaction sequence that could have taken place on tidal beaches; it requires a buffered ocean, emerged land and a nitrosating atmosphere. We show that the primitive Earth during the Hadean may have satisfied all of these requirements. This scenario is not necessarily what actually happened, but it represents a global approach of peptide prebiotic synthesis, and most of its parts are accessible to experiment. As it develops, it may open up a gateway to the emergence of homochirality and the catalytic activities of peptides. 5.1 From N-carbarmoyl Amino Acids (CAA) to Peptides
Reliability analysis of empirical predictive models for earthquake-induced sliding displacements of slopes Analyse de fiabilité des modèles empiriques de prédiction des déplacements sismiques de pentes

The goal of this study is twofold: (i) to identify the influence of the earthquake characteristics on the magnitude of the residual co-seismic slope displacements of a typical slope using different predictive analytical models and (ii) to compare the results of the analytical models with an exact fully dynamic non-linear analysis. In particular, three analytical models were used to predict the permanent slope displacements: the classical Newmark rigid block model, the decoupled Rathje and Antonakos model and the coupled Bray and Travasarou sliding block model. In addition, 2 dimensional fully non-linear numerical analyses were performed using the code FLAC for idealized sand and clayey step-like slopes considering different real acceleration time histories as input motion. All three models predict displacements that are generally in good agreement with the numerical results for the sand slope case. On the contrary, for the clay more flexible slope the correlation is not so good. However it is shown that the some crucial parameters, like the frequency content of the input motion, are not always appropriately captured in all analytical models. RÉSUMÉ : L'objectif de cette étude est (i) d'identifier l'influence des caractéristiques du tremblement de terre sur l'ampleur des déplacements co-sismiques résiduels d’une pente, en utilisant différents modèles analytiques et (ii) de comparer les déplacments analytiques avec une analyse numérique plus élaborée. En particulier, trois modèles différents étaient utilisés pour estimer les déplacements permanents : le modèle de base de bloc rigide de Newmark, le modèle découplé de Rathje et Antonakos et le modèle couplé de Bray et Travasarou. L’analyse numérique a été effectuée sur la même pente avec le code FLAC et pour les mêmes matériaux de sol (sable et argile). Dans le cas de pente sableuse les déplacements calculés par les trois modèles analytiques sont généralement en relativement bon accord avec les résultats numériques. La comparaison est moins bonne pour la pente argileuse. Néanmoins il a été démontré que tous les modèles analytiques ne tiennent pas en compte proprement quelques paramètres importants comme la fréquence du mouvement fort des sols.
