Enhanced modeling features within TREETOPS

The original motivation for TREETOPS was to build a generic multi-body simulation and remove the burden of writing multi-body equations from the engineers. The motivation of the enhancement was twofold: (1) to extend the menu of built-in features (sensors, actuators, constraints, etc.) that did not require user code; and (2) to extend the control system design capabilities by linking with other government funded software (NASTRAN and MATLAB). These enhancements also serve to bridge the gap between structures and control groups. It is common on large space programs for the structures groups to build hi-fidelity models of the structure using NASTRAN and for the controls group to build lower order models because they lack the tools to incorporate the former into their analysis. Now the controls engineers can accept the hi-fidelity NASTRAN models into TREETOPS, add sensors and actuators, perform model reduction and couple the result directly into MATLAB to perform their design. The controller can then be imported directly into TREETOPS for non-linear, time-history simulation

Pricing Models for Perishable Goods with Customer Perception

In this paper, the pricing problem for perishable goods with customer perception is studied. Firstly, the customer value theory is introduced. Secondly, the problem is described. Then, the pricing model of perishable goods is established, in consideration of customer perception. At last, some data analysis and discussion are made via a concrete case study, the optimal pricing policy and maximum expected profit of the retailers are gained and some useful management conclusions are drawn

ANALYSIS OF VIPAKA (METABOLIC TRANSFORMATION) OF AN EXTRA-PHARMACOPOEIAL DRUG-BRIDELIA STIPULARIS (L.) BLUME

Objective: The objective of the present study is to explore the vipaka of an extra-pharmacopoeia drug Bridelia stipularis (L.) Blume belongs to the Euphorbiaceae family. Methods: 12 Wistar strain albino rats were selected and divided into 2 groups; Group A-Control, Group B-Test group. Each rat was kept in separate metabolic cages provided with a constant amount of water and food per day. Assessment of vipaka was done based on the consumption of food, consumption of water, the quantity of faecal matter, urine output, and quantity of water content of expelled faecal matter per day. Assessment of Vipaka was done on the basis of consumption of food; consumption of water; the quantity of faecal matter, urine output and quantity water content of expelled faecal matter per day. Assessment of Vipaka was done on the basis of consumption of food; consumption of water; the quantity of faecal matter, urine output and quantity water content of expelled faecal matter per day. Results: Absolute values of Group B or test group exhibited significant increase in water consumption (p<0.01), wet faecal matter (p<0.05), dry faecal matter (p<0.001), and food conversion ratio (p<0.05), and non-significant increase in food consumption, urine output, faecal water, and body weight. Conclusion: Based on the preliminary analysis it may be concluded that the drug Bridelia stipularis (L.) Blume possess Madhura vipaka (Sweet metabolic transformation)

A study on constraints in adoption of scientific aquaculture practices

A study was undertaken to ascertain constraints faced by fish farmers in adoption of scientific aquaculture practices in East Champaran and West Champaran districts of Bihar. Information from 144 respondents was collected and analysed by calculating the Rank Based Quotient (RBQ) values. RBQ value for constraint faced by farmers were extreme climatic conditions (84.03), less extension programs and technical support (78.47), lack of contact with extension personnel’s (71.33), lack of awareness about scientific culture practices (65.28), inadequate credit facility (60.42), labour scarcity (57.64) and higher cost of material input (52.08).These constraints could be categorised under five heads namely extension constraints, financial constraints, production constraints, marketing constraints and social constraints. Average RBQ value for constraints related to extension was found to be 71.76 and ranked first. This was followed by financial constraint with RBQ value of 52.78. Production related constraint ranked third with an average RBQ value of 49.3 followed by marketing (32.87) and social constraints(27.08). Hypothesis that there is no significant difference with reference to rankings of constraints was tested by single factor ANOVA. Null hypothesis was rejected as Ftab=3.48>FNcal=2.61 with df=4 at 5% level of significance. There was a significant difference with reference to rankings of constraints. As the extension related constraints had the highest average RBQ value, it is clear that there is an urgent need of making effective strategy, engaging more fisheries extension professionals in this field along with capacity development of the existing extension professionals

Authorship and Collaboration Pattern in SRELS Journal of Information Management during 2008-2017: An Evaluation

The present study is an evaluation of authorship and collaboration pattern in SRELS Journal of Information Management during 2008-2017. Total 578 articles published during the study period out of which 196 articles are published by single author and rest 386 articles are published by two or more than two authors. It is clear from the study that multiple authorship pattern is prominent in the journal. In the study it has been counted that the average collaboration index is 1.86, average collaboration coefficient is 0.36, average degree of collaboration is 0.66, average relative growth rate is 0.32 and average doubling time is 3.40 during 2008-2017. The highest activity index for India is counted in the year 2009 and lowest activity index is counted in the year 201
