in this paper, a new analytical method to find a near-optimal high gain controller for the non-minimum phase affine nonlinear systems is introduced. this controller is derived based on the closed form solution of the hamilton-jacobi-bellman (hjb) equation associated with the cheap control problem. this methodology employs an algebraic equation with parametric coefficients for the systems with s...

We demonstrate a three stage procedure for mine detection. The rst phase locates plausible candidates through a series of hypothesis tests. The second state nds the globally optimal convex set containing each candidate using \coarse-tone" dynamic programming. The third stage re nes the mine shape estimates using the knowledge contained in a mine-shape library.

The current art in optimal combinatorial auctions is limited to handling the case of single units of multiple items, with each bidder bidding on exactly one bundle (single minded bidders). This paper extends the current art by proposing an optimal auction for procuring multiple units of multiple items when the bidders are single minded. The auction minimizes the cost of procurement while satisf...

We present a new method to parameterize Type Ia Supernovae (SN Ia) multi-color light curves. The method was developed in order to analyze the large number of SN Ia multi-color light curves measured in current high-redshift projects. The technique is based on empirically modeling SN Ia luminosity variations as a function of phase, wavelength, a shape parameter, and a color parameter. The model i...

This paper introduces the high efficiency operation of switched reluctance generator (SRG). The proposed SRG operates under the rated speed. The high efficiency can be obtained by the optimal current shape which can make the total losses minimum. For this purpose, theoretical analysis of the copper and core loss is done. In addition, a modified angle position control (MAPC) method which can get...

In the field of electrical solar power conversion EMC is of topical importance. In common single-phase inverter applications the current of the solar array shows a pronounced ripple. This entails two significant disadvantages: Reduced over-all efficiency due to dynamic maximum power point mismatch and reduced lifetime of the panels due to additional component stress. Furthermore, the output of ...
