## Abstract The problem of the static output feedback stabilization is the solvability of the two invertβcoupled matrix inequalities. This is nonβlinear optimal problem and cannot be solved directly. In this paper, the relation of the two coupled matrix inequalities is studied and a sufficient cond

β¦ Synopsis
In the present work the thermal behavior of a typical solar still i.q examined experimentally and theoretically and its basic characteristics are analyzed. It is concluded from a large number of experimental measurements that the operation of such stills during daytime is characterized by three phases: (1) starting, (2) pseudo steady-state, and (3) saturation. A mathematical equation is formed for the instantaneous simulation of the solar still during the pseudo steady-state phase. From this the equation in its integrated form determines satisfactorily the daily output by the daily solar radiation (solar energy inpu0, the average ambient air temperature during the day, T~av), and the temperature of the water in the basin at the beginning of the day, Twi n , as parameters. This method is called the "input-output" method.

Consider a ligand-gated channel with n agonist binding sites which can undergo desensitization. We present a theoretical experimental procedure for pinpointing the principal receptor state from which there is a transition to the desensitized state. The method is based on the observation that the dep
