We consider the problem of locating two unknown elements x; y using group testing devices. Assuming that up to a given number E of tests out of Q can give erroneous feedback, we provide optimal algorithms to search for x and y.

In this paper we provide a finite set of candidates to be one of the endpoints of an optimal rapid transit line for the problem of locating simultaneously a service facility and a rapid transit line. & 2012 Elsevier Ltd. All rights reserved.

This paper presents an algorithm to track an industrial robot hand during its movement. Based on acquired image and knowing the robot hand model, the pose is obtained. This information is used to move a pan-tilt camera and keep the robot hand centered in the image every time using an adaptive fuzzy logic controlled. This control law is used combined with a position prediction technique to impro...

This paper presents a systems analysis perspective that extends the traditional process design framework to green process design, green energy and industrial ecology leading to sustainability. For green process design this involves starting the design decisions as early as chemical and material selection stage on one end, and managing and planning decisions at the other end. However, uncertaint...

now a days, management and control of perishable inventories is important in many units and industrial enterprises. basically perishable inventory management and control is more complex and challenging than inventories with unlimited lifetime. hence determining the optimal inventory policies for these products is very important.  in this paper, the optimal inventory policy for perishable items ...
