We consider a wireless sensor network (WSN) where K sensors must deliver a message within a frame of N time slots by spending a given finite energy. If the message is not transmitted within the required delay then it becomes useless and the residual energy is wasted. The channel is block-fading, with independent fades for each sensor and each slot. Sensors know the fading levels up to the curre...

We investigate the optimal allocation of effort to a collection of n projects. The projects are 'restless' in that the state of a project evolves in time, whether or not it is allocated effort. The evolution of the state of each project follows a Markov rule, but transitions and rewards depend on whether or not the project receives effort. The objective is to maximize the expected time-average ...

policy capacity focuses on the managerial and organizational abilities to inform policy decisions with sound research and analysis, and facilitate policy implementation with operational efficiency. it stems from a view of the policy process that is rational and positivistic, in which optimal policy choices can be identified, selected, and implemented with objectivity. by itself, however, policy...

A multiple optional vacation policy for the unreliable server batch arrival queueing system with essential and multi optional services under N-policy is investigated. According to vacation policy, the server takes an essential phase of vacation after the completion of service of an individual customer when queue becomes empty. On returning from the vacation, if the server finds the queue empty,...

We examine an economy with n production sectors that interact via a production externality We nd a solution to the resulting dynamic di erential game between sectors and compare it to the cooperative solution As the number of sectors increases the limiting policy is the optimal policy without a production externality This policy is ine cient and depending on the sign of the externality between ...

MNDO semi-empirical SCF MO calculations are used to study the pyramidal nitrogen atom inversion and configurational equilibria in the title compounds.

There is no standard policy regarding the regulatory or institutional approval of N-of-1 trials in the United States. The objective of this study was to examine whether institutional review boards (IRBs) accredited by the Association for the Accreditation of Human Research Protection Programs (AAHRPP) consider N-of-1 trials as meeting the definition of human subjects research (45CFR46.102) and ...
