In the common polynomial regression model of degree m we consider the problem of determining the D-and D 1-optimal designs subject to certain constraints for the D 1-eeciencies in the models of degree m ? j; m ? j + 1; : : : ; m + k (m > j 0; k 0 given). We present a complete solution of these problems, which on the one hand allow a fast computation of the constrained optimal designs and on the...

This paper describes an optimal guidance policy for a vehicle to reach a relative position to a target, using information from a single fixed camera. Applying an extended Kalman filtering method, both of a velocity and a position of the vehicle relative to the target, can be estimated. However, estimates of a distance between the vehicle and the target are much worse than those of the other sta...

Discrete choice experiments (DCEs) are frequently used to estimate and forecast the behavior of an individual's choice. DCEs based on stated preference; therefore, underlying experimental designs required for this type study. According psychologists, DCE consist a small number sets with limited size in alternatives within set increase response efficiency questionnaire. Even though algorithmic c...

This paper presents an explicit construction of a class optimal-access, minimum storage regenerating (MSR) codes, for small values the number $d$ helper nodes. The is valid any parameter set notation="LaTeX">$(n,k,d)$ with notation="L...

In contrast to the classical discrete choice experiment, the respondent in a rank-order discrete choice experiment, is asked to rank a number of alternatives instead of the preferred one. In this paper, we study the information matrix of a rank order nested multinomial logit model (RO.NMNL) and introduce local D-optimality criterion, then we obtain Locally D-optimal design for RO.NMNL models in...

The first enzyme of the pathway for uridine diphosphate N-acetyl-D-glucosamine (UDPAG) biosynthesis i.e. L-glutamine: D-fructose 6-P amidotransferase (E.C. 2.6.1.16) was purified 52-fold from human placenta using methanol fractionation and column chromatography on DEAE-Sephadex A-50. The enzyme showed optimal activity in a broad range of pH from 5.8 to 7.8 in both phosphate and cacodylate ...
