Broadcasting on Faulty Hypercubes

In this paper we propose a method for constructing the maximum number of edge-disjoint spanning trees (in the directed sense) on a hypercube with arbitrary one faulty node. Each spanning tree is of optimal height. By taking the common neighbor of the roots of these edge-disjoint spanning trees as the new root and reversing the direction of the directed link from each root to the new root, a spa...

On Faults and Faulty Programs

A fault is an attribute of a program that precludes it from satisfying its specification; while this definition may sound clear-cut, it leaves many details unspecified. An incorrect program may be corrected in many different ways, involving different numbers of modifications. Hence neither the location nor the number of of faults may be defined in a unique manner; this, in turn, sheds a cloud o...

Logical consideration on lockout and trapped key interlock for machine.

"Lockout" is an important method for hazardous energy control to protect humans working at a place where they may be injured by unexpected release of hazardous energy. Actually, this administrative control is used in order to compensate for the incompleteness of the ZMS (Zero Mechanical State). This paper proposes the basic requirements for the "Lockout" used for machine maintenance work by app...

Shy-Drager syndrome: recognition and management.

Shy-Drager syndrome is an uncommon disorder in which the patient experiences progressive autonomic failure. It is a multisystem degenerative disease that involves the central autonomic, cerebellar, basal ganglia, pyramidal, or spinal motor neurons. The mean age of onset is 55 years. A male predominance is noted, with a 2 or 3:1 ratio. About 11 percent of patients with orthostatic hypotension ha...
