Verification And Validation Of The Devs Models

Simulation remains attractive for teaching, training and performance analysis of computer networks. This paper presents a robust simulation environment targeted for teaching and learning the complex dynamics of computer networks. The general-purpose DEVS-Suite simulator supports animation with I/O and state trajectories of computer network models developed using parallel DEVS modeling approach. The simulator offers high-level model abstraction as compared with simulators such as ns-2. The combined capabilities afforded by the robust DEVS-Suite simulator assists in understanding the fundamentals of computer network topologies and the logics of communication protocols. This newly developed DEVSSuite offers an expressive, yet relatively simple to use, simulation environment for students and educators to develop and experiment with computer network models. The paper concludes with observations on the proposed modeling approach and outline some evaluations. In this paper we discuss verification and validation of DEVS simulation models. Four different approaches to deciding model validity are described; two different paradigms that relate verification and validation to the model development process are presented; various validation techniques are defined; conceptual model validity, model verification, operational validity, and data validity are discussed; a way to document results is given; a recommended procedure for model validation is presented; and model accreditation is briefly discussed.
Field assessment of CaMsrB2 transgenic lines in a drought stress environment

Two drought-tolerant transgenic rice lines, L-8 (single copy) and L-23 (two copy), expressing the Capsicum annuum methionine sulfoxide reductase B2 (CaMsrB2) gene were selected for stress tolerance phenotyping under drought stress conditions. The two transgenic lines were selected on the basis of laboratory experiments and for performing well against drought. Field assessment of CaMsrB2 transgenic lines L-23 and L-8 in a drought stress environment was conducted. For the assessments, small plots were prepared at the Department of Botany of the University of Karachi to test the physiological response of transgenic lines. Relative water content, quantum yield (Fv/Fm ratio), photochemical quenching (qP) photosynthetic pigments, and performance index were high in transgenic lines compared to the wild type (WT). Antioxidant enzymes as represented by catalase and superoxide dismutase activities were increased while H2O2 production was decreased in transgenic lines compared to the WT. The results are discussed with special reference to physiological response of the transgenic lines against drought in field conditions.
The horizontal branch luminosity vs metallicity in M31 globular clusters

Context. Thanks to the outstanding capabilites of the HS T, our current knowledge about the M31 globular clusters (GCs) is similar to our knowledge of the Milky Way GCs in the 1960s-1970s, which set the basis for studying the halo and galaxy formation using these objects as tracers, and established their importance in defining the cosmic distance scale. Aims. We intend to derive a new calibration of the MV (HB)-[Fe/H] relation by exploiting the large photometric database of old GCs in M31 in the HS T archive. Methods. We collected the BVI data for 48 old GCs in M31 and analysed them by applying the same methods and procedures to all objects. We obtained a set of homogeneous colour-magnitude diagrams (CMDs) that were best-fitted with the fiducial CMD ri dge lines of selected Milky Way template GCs. Reddening, metallicity, Horizontal Branch (HB) luminosity and distance were determined self-consistently for each cluster. Results. There are three main results of this study: i) the relation M V(HB)=0.25(±0.02)[Fe/H]+0.89(±0.03), which is obtained from the above parameters and is calibrated on the distances of the template Galactic GCs; ii) the distance modulus to M31 of (m-M)0=24.42±0.06 mag, obtained by normalising this relation at the refer ence value of [Fe/H]=‐1.5 to a similar relation using V0(HB). This is the first determination of the distance to M31 ba sed on the characteristics of its GC system which is calibrat ed on Galactic GCs; iii) the distance to the Large Magellanic Cloud (LMC), which is estimated to be 18.54±0.07 mag as a consequence of the previous results. These values agree excellently with t he most recent estimate based on HS T parallaxes of Galactic Cepheid and RR Lyrae stars, as well as with recent methods.
The use of variotherm systems for microinjection molding

Microinjection molding (μIM) is a fast-developing technology which is used to produce polymeric microcomponents or components with micro/nanoscale features, such as are used in many fields including microfluidic diagnostics, microneedle drug delivery devices, microgears, and microswitches. The capabilities and performance of the microinjection molding process can be improved by incorporating a variotherm system. This leads to improved component quality, especially for high aspect ratio features. It can also help to increase the polymer flow path, improve feature replication, reduce residual stresses and molecular orientations, and also can eliminate weld lines. This article reviews the use of different variotherm systems in μIM, and describes how simulation of its use can provide insight when designing a mold cavity or a component with challenging microfeatures. The article highlights important problems, challenges and areas for further research. An increased understanding of these issues will provide opportunities to enhance further developments in the μIM process. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 42962.
The hypoglycemic effect of oleanolic acid which extracted from Alhagi Roots in diabetic rabbits by improve antioxidant defenses

This research include extractoleanolic acid (OAA) from Alhagi roots was administered orally to diabetic rabbits induced by alloxan once per day for one month. This treatment has been given significant decreasing of blood glucose, lipids and lipid peroxidation levels (malondiadehyde MDA). In addition, the levels of antioxidant enzymes, catalase (CAT) and superoxide dismutase (SOD) decreased in diabetic rabbits however these levels returned to normal when treated by oleanolic acid. From this results can suggest the oxidative stress plays important role in diabetes, and treatment with oleanolic acid useful in controlling not only for glucose and lipid levels, but these components may be also improvement the antioxidants potential.
Phytoplankton and bacterioplankton biomass, production and turnover in a semi-enclosed embayment with spring tide induced upwelling

We examined the short time scale (i.e. hours to days) responses of phytoplankton and heterotrophic bacteria to a spring tide-driven upwelling, which is different from classical wind-driven systems, in southern Taiwan in a semi-enclosed embayment. Results showed that nitrate concentrations (NO 3 - . 70 m was -60 mmol N m -2 h -1 with <1% of it utilized by phytoplankton. Chlorophyll a concentrations doubled from 0.07 to 0.16 μg l -1 in the 9 h after the upwelling to maximal concentrations of <0.30 mg l -1 . Euphotic zone integrated primary production (IPP, ca. 118 to 389 mgC m -2 d -1 ), and algal turnover rate (Pμ, ca. 0.27 to 0.76 d -1 ) responded to the upwelling ∼5 h earlier than chlorophyll. The observed uncoupling between upwelled nutrients and the low chlorophyll phenomenon might be due to quick tidal mixing and shorter residence time of the water mass (<1 d) within the bay, in comparison to the algal turnover time (1.3 to 3.7 d). Euphotic zone integrated bacterial production (17 to 28 mg C m -2 d - 1) and bacterial turnover rate (0.6 to 0.8 d -1 ) were positively correlated with IPP, Pμ and depth integrated particulate organic carbon (ca. 540 to 6575 mg C m -2 ) concentrations, suggesting a high possibility of 'bottom-up' (organic substrate supply) control. This was confirmed by the results of 3 enrichment experiments showing that bacterial growth was C limited. Our study provides mechanistic information regarding the magnitude of the interaction between physical, chemical and biological processes, since the time scale adopted by this study encompasses the turnover times of auto- and heterotrophic plankton.

H2O self-diffusion coefficient of water-rich MX-80 bentonite gels

Abstract MX-80 is a bentonite clay from the Clay Spur bed, Wyoming, USA, consisting of ~80 wt. % Na-rich montmorillonite and is a leading candidate material for use in engineered barriers within underground nuclear waste disposal sites in Switzerland and Sweden. The diffusive invasion of groundwater into the engineered barriers is likely to cause the dry high-density bentonite to swell and evolve into a less-dense, water-rich gel during re-submergence of the shafts and galleries. Data on H2O diffusivity within water-rich bentonite gels are therefore essential to the safe design of the engineered barriers. To address this need, the self-diffusion coefficient, D, of 1H2O molecules in water-rich MX-80 bentonite gels was measured using the pulsed-gradient spin-echo method of 1H nuclear magnetic resonance spectroscopy at 0.47 T; D was measured over a wide range of temperatures (20.6-70.1°C) and of bentonite volume fractions (0 to 17.2 vol.%). The results showed that D increased markedly to values of bulk water self-diffusivity as the bentonite volume fraction decreased towards 0 vol.%. The activation energy of the diffusion process for the gels was approximately equal to that for bulk water. As a result, the normalized H2O self-diffusivity, D/D0, was approximately independent of temperature, where D0 is D in bulk water. The D/D0 data for ≤6.39 vol.% bentonite fraction were successfully fitted to a porous clay gel model that involves unbound water molecules that diffuse in the pore space by avoiding randomly placed discoidal obstacles (clay particles) of a high aspect ratio. The D/D0 data for MX-80 were similar to data for SWy-2 (Wyoming bentonite from the Newcastle formation) and Kunigel-V1 (bentonite from Yamagata, Japan), suggesting that all three bentonites are equally suitable candidate materials, in terms of water diffusivity performance, for use within engineered barriers.
Psychological Capital: A Positive Approach to Enhance Commitment to Change among University Students

Higher Education Institutions need to engage in planned change initiatives in order to enhance the quality of higher education. However, gaining commitment for such change efforts is still problematic. Even though, considerable scholarly work has been devoted to commitment to change over the years it remains as an issue. Following this problem, the study aimed to investigates the impact of Psychological Capital (PsyCap) on dimensions of commitment to change (i.e. Affective Commitment to Change, Continuance Commitment to Change, and Normative Commitment to Change). The respondents of the study were undergraduates of Faculty of Management Studies of Sabaragamuwa University of Sri Lanka. Data were collected through a standard and validated questionnaire survey. Survey resulted in 396 usable questionnaires. SPSS 21 and Amos 16 were used to analyze data. Results suggest that PsyCap positively and significantly related to affective commitment to change, normative commitment to change and negatively affects continuance commitment to change. The results imply the importance of Psychological capital in enhancing affective and normative commitment to change while minimizing negative effects of continuance commitment. This research makes a novel contribution by being among the first to examine the impact of Psychological Capital in explaining commitment to change among university students.
AN SNP MARKER POTENTIALLY LINKED TO SOMATIC EMBRYOGENESIS OF OIL PALM (Elaeis guineensis)

Oil palm ( Elaeis guineensis ) is one of the most important oil-bearing crop in the world. This crop can be vegetatively propagated only using tissue culture technique. Oil palm tissue culture technique has low efficiency, with callogenesis and embryogenesis stages as the limiting factors. Genetic factor has a major role in determining the success rate of these two stages. The use of molecular markers which represent the rate of embryogenesis or callogenesis has the potential to improve the efficiency of oil palm tissue culture process. In this study, SNP mining was conducted on embryogenesis transcriptome data, oil palm cDNA database, oil palm genome database, and oil palm SNPs marker database in NCBI. The objective of this study was to obtain SNP marker which represents the embryogenesis potential, to be further used in marker assisted selection of oil palm ortets. One SNP (EMB6) showed significant association with embryogenesis rate. This SNP was found in one of Auxin Response Factor (ARF) family gene. Nucleotide replacement from Adenine to Guanine changed the 307 th amino acid from Isoleucine to Methionine. Oil palms with Adenine homozygote (A/A) pattern on the EMB6 showed 8-fold higher chance to produce significantly higher embryogenesis rate than Adenine-Guanine heterozygote (A/G).
ADOPTION AND EFFECTIVENESS OF LOGISTICS INFORMATION SYSTEM IN LOGISTICS SERVICE COMPANIES.

The logistics sector in India has today become an area of priority. India's logistics service industry is forecasted to become an over Rs 5.55 lakh crore ($120.42 billion) market by 2014, driven by growth in the manufacturing sector as revealed in the study by global consultancy Frost and Sullivan. It is necessary to streamline the logistics process to maintain the efficiency of the logistics network. In addition to integrating information technology and advanced logistical approaches into their business operations, firms are beginning to realize the need to focus on their logistics strategy in order to efficiently maintain their supply chain capabilities. Purpose: The purpose of this paper is to identify and understand the organizational characteristics of Logistics Service Companies (LSC) in the study area where the Logistics Information System (LIS) is in use. Further in the present study an attempt was made to identify the factors underlying the effectiveness of Logistics Information System (LIS). Research methodology/Design/Approach: A review of main stream literature was carried out to identify the factors underlying the effectiveness of LIS. A total of 125 Logistics Service Companies were first listed as using LIS. Out of which 12 companies were excluded from the study as they did not participate in the survey even after repeated contacts. Hence census study had been adopted to contact the remaining 113 respondents. The data were collected using a structured questionnaire and analyzed with SPSS 18.0 in order to identify the factors for effectiveness of LIS. One way ANOVA was used for testing the hypotheses. Findings: The analysis revealed the factors underlying the effectiveness of LIS, namely organizational impact, user satisfaction, communication effectiveness, top management support and individual impact. It was found that the factors underlying the effectiveness of LIS did not vary with the size of the companies, amount spent for adopting LIS and years of LIS usage except one factor. It was found that the factor ‘individual impact’ varies with the amount spent for adopting LIS and years of LIS usage. Originality/value: The study addresses the lack of empirical research on how companies effectively use LIS in managing Logistics operations in India as it was evident the review of literature.

The Common Principal Component (CPC) Approach to Functional time Series (FTS) Models

The functional time series (FTS) models are used for analyzing, modeling and forecasting age-specific mortality rates. However, the application of these models in presence of two or more groups within similar populations needs some modification. In these cases, it is desirable for the disaggregated forecasts to be coherent with the overall forecast. The 'coherent' forecasts are the non-divergent forecasts of sub-groups within a population. Reference [1] first proposed a coherent functional model based on product and ratios of mortality rates. In this paper, we relate some of the functional time series models to the common principal components (CPC) and partial common principal components (PCPC) models introduced by [2] and provide the methods to estimate these models. We call them common functional principal component (CFPC) models and use them for coherent mortality forecasting. Here, we propose a sequential procedure based on Johansen methodology to estimate the model parameters. We use vector approach and make use of error correction models to forecast the specific time series coefficient for each sub-group.
A Comparison of Concurrent Correctness Criteria for Shared Memory Based Data Structure

Developing concurrent algorithms requires safety and liveness to be defined in order to understand their proper behavior. Safety refers to the correctness criteria while liveness is the progress guarantee. Nowadays there are a variety of correctness conditions for concurrent objects. The way these correctness conditions differ and the various trade-offs they present with respect to performance, usability, and progress guarantees is poorly understood. This presents a daunting task for the developers and users of such concurrent algorithms who are trying to better understand the correctness of their code and the various trade-offs associated with their design choices and use. The purpose of this study is to explore the set of known correctness conditions for concurrent objects, find their correlations and categorize them, and provide insights regarding their implications with respect to performance and usability. In this thesis, a comparative study of Linearizability, Sequential Consistency, Quiescent Consistency and Quasi Linearizability will be presented using data structures like FIFO Queues, Stacks, and Priority Queues, and with a case study for performance of these implementations using different correctness criteria.
Morphological characteristics, nutritive quality, and methane production of tropical grasses in Brazil

The objective of this work was to evaluate three tropical forage species for their in vitro methane (CH4) production and organic matter degradability, in order to determine the relationships between forage grass nutritive quality and CH4 production. Guinea grass (Megathyrsus maximus), palisade grass (Urochloa brizantha), and signal grass (Urochloa decumbens) were evaluated. Palisade grass showed the highest organic matter, neutral detergent fiber, acid detergent fiber, lignin, and lower-crude protein content. Signal grass had the highest values for hemicellulose and neutral detergent fiber-nitrogen, and the lowest-cellulose content. Guinea grass and signal grass showed a higher-total gas production than palisade grass. Besides, Guinea grass showed an increased CH4 production, and palisade grass showed lower value for truly degraded organic matter, and reduced partitioning factor, in comparison to signal grass. An increased CH4 production was observed in cases of lower hemicellulose and paratitioning factor. The nutritive value and CH4 production of forages may be employed as parameters, aiming at the sustainability of ruminant production.
The Relationship Between Normative Commitment and Turnover Intentions: Case Study of Five Private Turkish Banks in Ankara

This paper analyzes the connection between normative commitment and turnover intentions of Turkish bank employees, in Ankara, Turkey. Research methodology was comprised from the quantitative research method utilizing one structured survey instrument consisting of 14 items (five for descriptive and nine for inferential statistics). A survey was carried out in a cross sectional time-frame study manner and the study that involved 130 participants was performed within five different private banks’ employees in Ankara, Turkey. The normative commitment and intention to leave were first analyzed for reliability. A Pearson product-moment correlation was run to determine the relationship between all variables of interest and there was a strong, negative correlation between normative commitment and the intention to leave, which was statistically significant (r = -0.323, n = 130, p < 0.000). This quantitative research shows that there was a strong, negative and statistically significant relationship between turnover intentions and normative commitment. It is very important to increase the commitment level of employees and decrease turnover intention for companies’ future.
