Consider a Bayesian optimal design with many support points which poses the problem of collecting data with a few number of observations at each design point. Under such a scenario the asymptotic property of using Fisher information matrix for approximating the covariance matrix of posterior ML estimators might be doubtful. We suggest to use Bhattcharyya matrix in deriving the information matri...

Energy harvesting for the purpose of powering low power electronic sensor systems has received explosive attention in the last few years. A common device uses the piezoelectric effect for a cantilever beams at resonance to harvest ambient vibration energy. However most of these devices have a rectangular piezoelectric patch covering all or part of the beam. This paper considers the optimum desi...

Economists argue that policymakers should take advantage of market principles in designing environmental regulations. Such market-based approaches – environmental taxes and cap-and-trade – use economic incentives to achieve environmental goals at lower costs. Market-based approaches have now become common due to near-unanimous advocacy by economists and early positive policy experiences. Despit...

Recent advances in IT have provided firms unprecedented ability to manage online social interactions. Despite growing popularity, few studies have examined firm's optimal design choices in firm-mediated social interactions. We examine whether and how a firm can enhance effectiveness of online social interactions, by simply varying message shared by referrers. We focus on two pieces of informati...

This paper investigates the role of the assumption of classconditional independence of object features in human classification learning. This assumption holds that object feature values are statistically independent of each other, given knowledge of the object’s true category. Treating features as classconditionally independent can in many situations substantially facilitate learning and catego...

Successful operation of entire power system depends to a considerable extent on efficient and satisfactory performance of substations. Hence substations in general can be considered as heart of overall power system. In any substation, a well designed grounding plays an important role. Since absence of safe and effective grounding system can result in mal-operation or non-operation of control an...

This paper investigates the hypothesis that the objective function of economic agents is non-separable in economic incentives and social preferences. We study fixed-prize contests in a 2 × 2 experimental design, varying orthogonally the degree of competition of the incentive mechanism (all-pay auction vs. lottery) and the presence or absence of social returns to bidding (public good vs. rent se...
