Measurements have been made of the perturbation magnetic field in front of a semi-infinite Rankine body moving parallel to a uniform impressed magnetic field in a conducting fluid. The purpose of these experiments was to investigate the so-called upstream wake effect which has been predicted by theory. It is believed that these are the first experiments in which the upstream wake was observed.
This project was dedicated to the problem of improving a non-invasive blood glucose monitor being developed by the VivaScan Corporation. The company has made some progress in the non-invasive blood glucose device development and approached WPI for a statistical assistance in the improvement of their model in order to predict the glucose level more accurately. The main goal of this project was to improve the ability of the non-invasive blood glucose monitor to predict the glucose values more precisely. The goal was achieved by finding and implementing the best regression model. The methods included ordinary least squared regression, partial least squares regression, robust regression method, weighted least squares regression, local regression, and ridge regression. VivaScan calibration data for seven patients were analyzed in this project. For each of these patients, the individual regression models were built and compared based on the two factors that evaluate the model prediction ability.
In this study, I examine whether the use of conservative accounting reporting mitigates the adverse consequences of covenant violations, such as restrictions on borrowing firms’ financing and investing activities. I also examine the implications of accounting conservatism, which can trigger quicker covenant violations (Zhang, 2008) and allow transfer of decision rights to lenders, for violating firms’ operating performance in the post-violation period. Accounting information has been extensively used in debt contracts (Leftwich, 1983; Dichev and Skinner, 2002) and the characteristics of accounting information have important implications for debt contracting. Particularly, Watts (2003a, b) argues that one of the accounting characteristics, conservatism, can enhance contracting efficiency because reporting conservatism can ensure lenders the minimum level of asset values at liquidations and thereby reduces lenders’ downside risk.
