    Notes: Purpose - The aim of the study is to develop a TQM model of academic excellence and empirically establish a relationship between TQM implementation and students' satisfaction of academic performance. Design/methodology/approach - A sample of students from ISO and non-ISO engineering institutions from South India has been taken for the study. Statistical measures like mean, t-test, correlation and regression analysis were used. Findings - The results reflect that ISO 9001:2000 engineering institutions are moving towards the path of TQM offering better quality of educational service than the non-ISO institutions. A relationship between the five TQM constructs and students' satisfaction of academic performance has also been established. Research limitations/implications - This study has been conducted in higher engineering education from the students' perspective only. The study is limited to the privately funded engineering institutions. Research relating to other types of institutions namely the government institutions and the deemed universities can be taken up in future. Practical implications - The academic excellence model developed in this paper can be effectively implemented in the higher educational institutions to enhance the quality of education and students' satisfaction. Originality/value - 5C TQM excellence model is unique. Suggestions to educational authorities interested in improving the quality of education are valuable.

    Notes: Abstract. Ca2+/calmodulin-dependent cyclic nucleotide phosphodiesterase (PDE1) is one of the key enzymes involved in the complex interactions between the cyclic nucleotide and Ca2+ second messenger systems. Currently, three genes encode PDE1, and alternate splicing of these genes gives rise to functionally different isozymes which exhibit distinct catalytic and regulatory properties. Some isozymes have similar kinetic and immunological properties but are differentially regulated by Ca2+ and calmodulin. These isozymes also differ in their mechanism of regulation by phosphorylation. Analysis of various regulatory reactions involving Ca2+ and cyclic adenosine monophosphate (cAMP) has revealed the importance of the time dependence of these reactions during cell activation; however, no measurement is available for the time of occurrence of specific regulatory reactions. cAMP-signalling systems provide a pivotal centre for achieving crosstalk regulation by various signalling pathways. It has been proposed that polypeptide sequences enriched in proline (P), glutamate (E), serine (S) and threonine (T), known as PEST motifs, serve as putative intramolecular signals for rapid proteolytic degradation by calpains. Calpains are Ca2+-dependent cysteine proteases that regulate various enzymes, transcription factors and structural proteins through limited proteolysis. Isozyme PDE1A2 has a PEST motif and acts as a substrate for m-calpain. In this paper, we have described PDE1A2 regulation by calpains and its physiological implications. cAMP is an important component of the signal transduction pathway and plays an integral role in various physiological processes such as gene transcription, various neuronal functions, cardiac muscle contraction, vascular relaxation, cell proliferation and a host of other functions. It is important to identify the cellular processes where PDE isoform(s) and cAMP response are altered. This will lead to better understanding of the pathology of disease states and development of novel therapeutics. The different PDE1 isozymes, although similar in kinetic properties, can be distinguished by various pharmacological agents. Our recent understanding of the role of PDE1 inhibitors such as ginseng, dihydropyridine antagonists and antiparkinsonian agents are described in this review. The exact function of PDE1 isozymes in various pathophysiological processes is not clear because most of the studies have been carried out in vitro; therefore, it is essential that further research be directed to in vivo studies.

    Notes: Conventional approaches for computational structural dynamics (CSD) relevant to time-integration methods involve first employing the classical Galerkin formulations for the spatial discretization to yield a set of ordinary differential equations in time and then employing finite difference approximations for deriving the appropriate step-by-step algorithms. And, almost all of the widely advocated (existing) step-by-step schemes for structural dynamics require an initial acceleration vector to be specified (evaluated) in addition to displacement and velocity vectors for starting the schemes. Unlike the above, in this paper we introduce new representations and architecture towards providing not only direct self-starting features with the elimination of acceleration computations but also for enhancing the computational architecture itself via several other inherent distinguishing characteristics. Thereby, a robust and effective methodology of computation is presented which is an extension of our previous efforts (see Tamma and Namburu3). In particular, to illustrate the basic concepts, in this paper we focus attention on the development of explicit time-integration formulations. The methodology involves expressing the governing dynamic equations of motion in conservation form, and firstly temporal discretization is accomplished in the spirit of Lax-Wendroff-type formulations. Therein, discretization in space is accomplished by introducing stress-based representations and employing the classical Galerkin scheme, and, quite naturally, we advocate employing finite elements as the principal computational tool because of its several inherent advantages. The stability and accuracy of the proposed formulations and the several added distinguishing features are briefly highlighted. Considerations on the effects of damping are additionally included and the introduction of general boundary conditions in a natural setting permits an effective generalized architecture for general applications. Numerical test models are presented to validate the overall developments for computational structural dynamics.

    Notes: The paper presents numerical simulations for the prediction of thermal-stress and deformation fields resulting from phase change in solidifying bodies employing new finite element representations. The formulations developed in this paper provide different perspectives and physical interpretation for the modelling/analysis of thermo-mechanical problems and possess several inherent advantages. In comparison to traditional approaches for solving similar problems, the paper employs new computational architectures in conjunction with flux/stress based representations to enhance the overall effectiveness. Comparative numerical applications validate applicability of the formulations for predicting the temperature induced deformations and stresses resulting from effects due to phase change.

In particular, in comparison to traditional methods of approach, new enthalpy-based architectures based on a generalized trapezoidal family of representations are presented which provide different perspectives, physical interpretation and solution architectures for effective numerical simulation of phase change processes encountered in solidification problems. Various numerical test models are presented and the results support the proposition for employing such formulations for general phase change applications.

    Notes: This paper discusses the implementation aspects and our experiences towards a data parallel explicit self-starting finite element transient methodology with emphasis on the Connection Machine (CM-5) for linear and non-linear computational structural dynamic applications involving structured and unstructured grids. The parallel implementation criteria that influence the efficiency of an algorithm include the amount of communication, communication routing, and load balancing. To provide simplicity, high level of accuracy, and to retain the generality of the finite element implementation for both linear and non-linear transient explicit problems on a data parallel computer which permit optimum amount of communications, we implemented the present self-starting dynamic formulations (in comparison to the traditional approaches) based on nodal displacements, nodal velocities, and elemental stresses on the CM-5. Data parallel language CMFortran is employed with virtual processor constructs and with:SERIAL and:PARALLEL layout directives for arrays. The communications via the present approach involve only one gather operation (extraction of element nodal displacements or velocities from global displacement vector) and one scatter operation (dispersion of element forces onto global force vector) for each time step. These gather and scatter operations are implemented using the Connection Machine Scientific Software Library communication primitives for both structured and unstructured finite element meshes. The implementation aspects of the present self-starting formulations for linear and elastoplastic applications on serial and data parallel machines are discussed. Numerical test models for linear and non-linear one-dimensional applications and a two-dimensional unstructured finite element mesh are then illustrated and their performance studies are discussed.

    Multiagent Systems Based Modeling and Implementation of Dynamic Energy Management of Smart Microgrid Using MACSimJX (2016)
    Hindawi
    Details
    Publication Date: 2016-04-05
    Description: The objective of this paper is implementation of multiagent system (MAS) for the advanced distributed energy management and demand side management of a solar microgrid. Initially, Java agent development environment (JADE) frame work is used to implement MAS based dynamic energy management of solar microgrid. Due to unstable nature of MATLAB, when dealing with multithreading environment, MAS operating in JADE is linked with the MATLAB using a middle ware called Multiagent Control Using Simulink with Jade Extension (MACSimJX). MACSimJX allows the solar microgrid components designed with MATLAB to be controlled by the corresponding agents of MAS. The microgrid environment variables are captured through sensors and given to agents through MATLAB/Simulink and after the agent operations in JADE, the results are given to the actuators through MATLAB for the implementation of dynamic operation in solar microgrid. MAS operating in JADE maximizes operational efficiency of solar microgrid by decentralized approach and increase in runtime efficiency due to JADE. Autonomous demand side management is implemented for optimizing the power exchange between main grid and microgrid with intermittent nature of solar power, randomness of load, and variation of noncritical load and grid price. These dynamics are considered for every time step and complex environment simulation is designed to emulate the distributed microgrid operations and evaluate the impact of agent operations.
