Production Optimization in Single Line Process by Simulation of Transfer Lines

Plant Simulation software permits the simulation and optimisation of production systems and processes. using Plant Simulation, you'll optimize material flow, resource utilization and supplying for all levels of plant designing from global production facilities, through native plants, to specific lines. Plant Simulation analysis tools allow simple interpretation of simulation results. statistical analysis, graphs and charts show the use of buffers, machines and personnel. you'll generate in depth statistics and charts to support dynamic analysis of performance parameters as well as line employment, breakdowns, idle and repair time and proprietary key performance factors. To optimize the performance of existing production systems by taking measures that are verified in a very simulation environment before implementation. The parameters of every method that affects the productivity and that is taken into account as focus of productivity improvement. Keywords- SIM, PLM, Transfer Line, Productio

In Vitro studies on antibacterial activity and phytochemical analysis of whole plant extracts of Stelleria media

The whole plant extracts of Stelleria media were examined for the presence of alkaloids and phenolics with simultaneous study on the antimicrobial properties of these extracts. Investigation was carried out using four different concentration (62.5, 125, 250 and 500 mg/ml) of extract to determine the quantitative effectiveness. Preliminary evaluation of both the aqueous and the chloroform fractions showed a broad spectrum of activity ((p<0.05)) since the extracts inhibit the growth of both gram positive and gram negative bacterial isolates. Clinical isolates used in present investigation were E.coli, S.typhi, K. pneumonia, Staph. Aureus, Pseudomonas aeruginosa, Bacillus subtilis. The phytochemical analysis revealed the presence of alkaloids, saponins, tannins, flavonoids, cardiac glycosides, anthraquinones and cyanogenetic glycosides in varying concentration. Both the chloroform and aqueous extracts inhibited the growth of the test organisms with Salmonella typhi and E.coli showing the highest susceptibility but the pathogens were found to be less sensitive for chloroform extract in comparison to the aqueous extract which could be due to the domination of antimicrobial activity of water soluble polar compounds. This research supports the local use of the plant, Stelleria media for prophylactic and therapeutic purposes against bacterial infection.Keywords: Stelleria media, Chickweed phytochemical analysis, antimicrobial activity, activity index, therapeutic purpos

Dynamic network analysis of a target defense differential game with limited observations

In this paper, we study a Target-Attacker-Defender (TAD) differential game involving one attacker, one target and multiple defenders. We consider two variations where (a) the attacker and the target have unlimited observation range and the defenders are visibility constrained (b) only the attacker has unlimited observation range and the remaining players are visibility constrained. We model the players' interactions as a dynamic game with asymmetric information. Here, the visibility constraints of the players induce a visibility network which encapsulates the visibility information during the evolution of the game. Based on this observation, we introduce network adapted feedback or implementable strategies for visibility constrained players. Using inverse game theory approach we obtain network adapted feedback Nash equilibrium strategies. We introduce a consistency criterion for selecting a subset (or refinement) of network adapted feedback Nash strategies, and provide an optimization based approach for computing them. Finally, we illustrate our results with numerical experiments.Comment: 8 figure

Class(es) of Factor-Type Estimator(s) in Presence of Measurement Error

When data is collected via sample survey it is assumed whatever is reported by a respondent is correct. However, given the issues of prestige bias, personal respect and honor, respondents’ self-reported data often produces over- or under- estimated values as opposed to true values regarding the variables under question. This causes measurement error to be present in sample values. This article considers the factortype estimator as an estimation tool and examines its performance under a measurement error model. Expressions of optimization are derived and theoretical results are supported by numerical examples

Biometric Personal Identification based on Iris Patterns

This paper discusses an analysis of human iris patterns for recognition of biometric system which consists of a segmentation system that is based on the Hough transform, and is able to localize the circular iris and pupil region, occluding eyelids and eyelashes, and reflections. The extracted iris region is then normalized into a rectangular block with constant dimensions to account for imaging inconsistencies. To encode the unique pattern of the iris into a bit-wise biometric template, 1D Log-Gabor filter is used.Finally to match two iris templates hamming distance is used as matching metric. The system performance is analyzed on 312 iris images taken from standard CASIA Iris Interval database version 4. To establish the verification accuracy of iris representation and matching approach, each iris image in the database is matched with all the other iris images in the database and genuine and imposter distribution is found .The performance of the system is implemented by evaluating the Decidability Index (DI), False match rate (FMR), False Non-match rate (FNMR), Genuine Accept Rate (GAR) and Equal error rate (EER)

Spirometric and anthropometric studies in normal children aged between 7 and 12 years

Spirometric data on 1183 healthy school children (551 boys and 632 girls) ranging in age from 7 to 12 years were analysed to derive predicted equations for (forced vital capacity, FEV 1 (forced expiratory volume in one second), FEF25-75% (maximal flow over the mid-portion of FVC), Vmax50% (flow rate after expiring 50% of FVC), and PEFR (peak expiratory flow rate). For all lung functions parameters, girls have lower values than boys. Using regression analysis, standing height appeared to be the most important predictor of pulmonary function across the age group. Regression equations constructed with logarithmically transfered dependent variables provided accurate predictions. Predicted FVC values derived from equation based on other population were higher than the observed mean in this study. This study therefore, reemphasises the need to be cautions when applying formulae derived from one population to another. Grossly erroneous conclusions may be reached unless predicted equations for lung parameters for a given are derived from studies base upon the same population group
