A University task force was in­ volved in developing a revised food and drink policy for the U n iv e r s i ty ’s l i b r a r i e s th is summer. A ccord ing to Sonja J o rd a n , assistant librarian and head of the task force, the policy, which prohibits food and drink in a r ­ eas of the library other than the pit, has always existed; the task fo rc e ’s aim w as to develop a means of enforci...

In this paper, we study N-policy for a finite population Bernoulli feedback queueing model for machine repair problem with degraded failure. The running times of the machines between breakdowns have an exponential distribution. The repair times of the machines are independent and identically distributed random variables. If at any time a machine fails, it is sent to the repairman for repairing,...

Let π be a nonidling fully collaborative policy. Under any fully collaborative policy, our model is equivalent to one where the service requirements of successive customers at station j ∈ {1, . . . , N} are independent and identically distributed (i.i.d.) with mean 1 αjγj , service rates of collaborating servers are additive, and the service rates depend only on servers, i.e., μij = μi for all ...

ion from any particular JVM implementation. This implementation of JML’s heap space support in ESC/Java2 has uncovered interesting problems concerning the interaction between the ”\working space” specification function and the machine state in which it is evaluated. Compilation from JML to a specification language for bytecode has been carried out at INRIA Sophia in the context of using program...

An empirical model is developed to estimate the effects of alternative farming practices on potential nitrogen runoff and leaching in 128,591 National Resources Inventory sites across the Midwest and the Northern Plains of the United States. This model integrates the effects of soils, climate, crops, and management practices on nitrogen loss. The model is applied to evaluation of two policy sce...

This paper looks at the convergence property of off-policy Monte Carlo agents with variable behaviour policies. It presents results about convergence and lack of convergence. Even if the agent generates every possible episode history infinitely often, the algorithm can fail to converge on the correct Q-values. On the other hand, it can converge on the correct Q-values under certain conditions. ...

I n setting monetary policy in 1995, the Federal Reserve sought to promote sustainable economic growth and continued progress toward price stability. Toward those ends, the Federal Reserve adjusted the stance of monetary policy three times in 1995. In February, amid signs of increasing inflationary pressures, policy was tightened. In July and December, in response to signals of a slowing econom...

This ecologic study evaluated the association between school policy allowing students to purchase sports drinks from school vending machines and school stores and student body mass index (BMI). Data were from surveillance surveys of Minnesota secondary schools (n = 238) and students (n = 59,617), administered in 2012 and 2013, respectively. We used generalized linear models to assess the associ...
