Incorporating Agile with MDA Case Study: Online Polling System

Nowadays agile software development is used in greater extend but for small organizations only, whereas MDA is suitable for large organizations but yet not standardized. In this paper the pros and cons of Model Driven Architecture (MDA) and Extreme programming have been discussed. As both of them have some limitations and cannot be used in both large scale and small scale organizations a new architecture has been proposed. In this model it is tried to opt the advantages and important values to overcome the limitations of both the software development procedures. In support to the proposed architecture the implementation of it on Online Polling System has been discussed and all the phases of software development have been explained.Comment: 14 pages,1 Figure,1 Tabl

Comparative Study of the Sn-Ag and Sn-Zn Eutectic Solder Alloy

The present work aimed at investigating the properties of Sn-Zn and Sn-Ag solder alloys and extensively focuses on the microstructure, thermal and mechanical properties. The compositions at their eutectic temperatures were weighed carefully in the weighing machine and were prepared after melting the binary system in the furnace at much higher temperatures than their respective eutectic temperatures. The microstructures of both the solder alloys were investigated using a Scanning Electron Microscope (SEM) and optical microscope. The composition and phase analysis of the solder alloys was done using Energy dispersive X- ray spectroscopy (EDS) and X- ray diffraction respectively. Differential scanning calorimetry (DSC) was carried out to find out the melting temperatures of the alloys. Fractography was done to find out the type of fracture under impact testing. Microhardness of the solder alloys were also found out and analysed. The wettability of the samples was observed under Scanning Electron Microscope(SEM) after soldering the alloys on the Copper circuit board. A thorough analysis was done after the experiments were conducted to find out a better solder alloy out of the two

Studies on physico-chemical, functional, pasting and morphological characteristics of developed extra thin flaked rice

AbstractPaddy (Oryza sativa L.) is among major staple food cereal crops of the world. The whole grain has higher percentage of vitamins, minerals and fiber as compared to milled rice grain. The present study was undertaken to study the physicochemical, functional, pasting and morphological characteristics of paddy (Gurjari variety) and its processed products were obtained during flaking. The major dimensions were highest for extra thin flaked rice (ETFR) with 17.08mm length and 8.50mm breadth at the expense of thickness found to be lowest 1.16. Thousand kernel weight (TKW), bulk density (BD), true density (TD) and porosity (POR) of ETFR were lowest as compared to other products. Frictional properties did not show any significant difference (p<0.05%) except for angle of repose. Significant difference was observed in chemical and functional properties of ETFR with exception to water absorption index (WAI) and water solubility index (WSI). Optical parameters L∗, a∗ and b∗ values of EFTR were found to be 73.72, 0.39 and 9.60, respectively significantly different from brown and roasted paddy. Peak and final viscosity was highest for brown rice (4419cP, 6351cP) and lowest for roasted rice (1058cP, 1525cP). Morphological changes occurring due to disintegration of starch granules within ETFR were clearly visible within its matrix caused by high mechanical force and temperature

Development of fully intuitionistic fuzzy data envelopment analysis model with missing data: an application to Indian police sector

Data Envelopment Analysis (DEA) is a technique used to measure the efficiency of decision-making units (DMUs). In order to measure the efficiency of DMUs, the essential requirement is input-output data. Data is usually collected by humans, machines, or both. Due to human/machine errors, there are chances of having some missing values or inaccuracy, such as vagueness/uncertainty/hesitation in the collected data. In this situation, it will be difficult to measure the efficiencies of DMUs accurately. To overcome these shortcomings, a method is presented that can deal with missing values and inaccuracy in the data. To measure the performance efficiencies of DMUs, an input minimization BCC (IMBCC) model in a fully intuitionistic fuzzy (IF) environment is proposed. To validate the efficacy of the proposed fully intuitionistic fuzzy input minimization BCC (FIFIMBCC) model and the technique to deal with missing values in the data, a real-life application to measure the performance efficiencies of Indian police stations is presented

Human Movement Analysis: Ballistic Dynamics, and Edge Continuity for Pose Estimation

We present two contributions to human movement analysis: (a) a ballistic dynamical model for recognizing movements, and (b) a model for coupling edge continuity with contour matching. We describe a Bayesian approach for visual analysis of ballistic hand movements, namely reaches and strikes. These movements are most commonly used for interacting with objects and the environment. One of the key challenges to recognizing them is the variability of the target-location of the hand~- people can reach above their heads, for something on the floor, etc. Our approach recognizes them independent of the movement's target-location and direction by modelling the ballistic dynamics. A video sequence is automatically segmented into ballistic subsequences without tracking the hands. The segments are then classified into strike and reach movements based on low-level motion features. Each ballistic segment is further analyzed to compute qualitative labels for the movement's target-location and direction. Tests are presented with a set of reach and strike movement sequences. We present an approach for whole-body pose contour matching. Contour matching in natural images in the absence of foreground-background segmentation is difficult. Usually an asymmetric approach is adopted, where a contour is said to match well if it aligns with a subset of the image's gradients. This leads to problems as the contour can match with a portion of an object's outline and ignore the remainder. We present a model for using edge-continuity to address this issue. Pairs of edge elements in the image are linked with affinities if they are likely to belong to the same object. A contour that matches with a set of image gradients is constrained to also match with other gradients having high affinities with the chosen ones. A Markov Random Field framework is employed to couple edge continuity and contour matching into a joint optimization process. The approach is illustrated with applications to pose estimation and human detection

Effect of cyclodextrin garcinol complex on isoproterenol-induced cardiotoxicity and cardiac hypertrophy in rats

Background: Garcinol is a polyisoprenylated benzophenone derivative present in the fruit rinds of Garcinia species namely Garcinia indica (common name 'Kokum') and Garcinia cambogia (common name 'Gombogee'). It appears to be involved in the regulation of oxidative stress and antioxidant capacity of heart tissue when the heart is subjected to oxidative stress in various pathogenic conditions/ chemical agent. But garcinol is associated with severe limitation of instability and poor bioavailability which can be improved complexing cyclodextrin with garcinol (garcinol complex). Objective: The objective of the present study was to investigate effect of cyclodextrin with garcinol complex (20 mg/kg), on Iso induced cardiotoxicity and cardiac hypertrophy in rats.Methods: Male Wistar rats (250-300g) were divided into following 4 groups of six animals each. Group 1 was control (distilled water 2 ml/kg/day orally for 18 days and water for injection by i.p. from day 9 to day 18), group 2 was cyclodextrin (cyclodextrin 2 ml/kg/day orally for 18 days and water for injection by i.p. from day 9 to day 18), group 3 Iso (distilled water 2 ml/kg/day orally for 18 days and isoproterenol 1 mg/kg by i.p. from day 9 to day 18), group 4 garcinol complex (20 mg/kg/day orally for 18 days and isoproterenol 1 mg/kg by i.p. from day 9 to day 18). After 24 hrs of last dose of isoproterenol, electrocardiogram (ECG) and heart rate were recorded in anaesthetized rats. The animals were sacrificed by overdose of ether. The hearts of animals were isolated for measurement of reduced glutathione (GSH) and lipid peroxidation (MDA). Results: Isoproterenol treated rats showed significant myocardial hypertrophy, decreased endogenous antioxidants when compared with the control group animals. The garcinol complex (20 mg/kg) treatment for 18 days showed significant cardioprotective activity by lowering the myocardial hypertrophy, level of lipid peroxidation (MDA content) as well as elevated the level of GSH. The results suggest pre-treatment of garcinol complex (20 mg/kg), may offer potential benefits in the management of cardiotoxicity and cardiac hypertrophy. Conclusion: It is thus concluded that Garcinol Complex (20 mg/kg) administration offered significant protection against isoproterenol induced cardiotoxicity and cardiac hypertrophy as well as decreased myocardial injury by preservation of endogenous antioxidants and reduction of lipid peroxidation in rat heart
