The maximum entropy principle: a generalized constraint-based entropy

Abstract: We have derived a new generalized constraint-based entropy on the basis of the maximum entropy principle. The new entropy which is very similar to, but different from Havrda and Charvat entropy and Tsallis entropy, reduces to the form of Shannon entropy in a limiting case. The characteristics properties of this new entropy have been pointed out.

Stiffened Spherical Shell with Cutout

Abstract: In this chapter, free vibration characteristics of laminated composite stiffened spherical shells with cutouts are studied using finite element method employing eight-noded curved quadratic isoparametric element for shell with three-noded curved beam element for stiffener formulation. Dynamic characters of stiffened spherical shells with different sizes and positions of the cutouts with respect to the shell centre for different edge constraints are analysed in the form of figures and tables. The results are analysed to arrive at guidelines for the selection of optimum size and position of the cutout with respect to shell centre considering different practical constraints.

Antidiabetic effect of mikania scandens on alloxan-induced rat model

Abstract: Objective: The objective was to study the evaluation of antidiabetic and antioxidant activity of different doses ethanolic extract of Mikania scandens leaves. Methods: The rats were divided into five groups of six animals each (non-diabetic control, diabetic control, standard drug-treated, and plant treated groups (250 and 500 mg/kg body weight)). Diabetes was induced in the healthy male Wistar rats (150–200 g body weight, 4–6 weeks old) by the administration of alloxan monohydrate (150 mg/kg, i.p.). On the 0th, 3th, 7th, 11th, and 15th days, the blood samples were analyzed for blood glucose. The antioxidant and antidiabetic parameters were evaluated by standard protocol. The liver tissue was used for histopathological assessment of liver damage. Results: The ethanolic extract of leaves of M. scandens showed a significant reduction (p<0.001) in the blood glucose levels and the antioxidant levels, with 500 mg/kg of body weight in the alloxan-induced diabetic rats as compared to the controls. Histopathological studies provided evidence that the leaf extract possesses antidiabetic activity. Conclusions: The ethanolic extract of leaves of M. scandens showed potent antidiabetic and antioxidant abilities against alloxan-induced rats, which indicate the presence of hypoglycemic constituents in the plant.

Efficient Data Structure for the Top-k Variation of Sports Auction

Abstract: In any sports auction, bidders may have fund constraints and purchasing the best team may not be possible for all. So, reporting k best teams in non-increasing order of total expenses might be helpful to them. Now, they have multiple options in their hands from which they can choose the best available team according to their fund constraints. In this paper, we deal with the top-k variation of sports auction, where we report k best teams (top-k teams) of fixed size in non-increasing order of total cost, which might help franchises to make decisions on buying players as per available budget. Teams are formed by choosing a predefined number of players from various categories where each player has his own cost. We initially present a basic technique where we construct a metadata structure G even before costs of players of various categories and k are known, so that we can later use G to report the top-k purchases efficiently when costs are available. We then extend our work by generating the required portions of G on the fly, so that no preprocessing is needed, which in turn improves the space complexity of the algorithm remarkably.

Stiffened Hyperbolic Paraboloid Shell with Cutout

Abstract: This chapter considers dynamic characteristics of stiffened composite hyperbolic paraboloid shell panel with cutout under free vibration in terms of natural frequency and mode shapes. Finite element method is used for the analysis by combining an eight-noded curved shell element with a three-noded curved beam element. The variations in cutout size as well as positions of the cutouts with respect to the shell centre are considered for different boundary conditions of cross-ply and angle-ply laminated shells. The effects of these parametric variations on the fundamental frequencies and mode shapes are studied in details to arrive at a set of conclusions of practical engineering relevance.
