The process of scheduling computations for Internet-based computing presents challenges not encountered with more traditional platforms for parallel and distributed computing. The looser coupling among participating computers makes it harder to utilize remote clients well and also raise the specter of a kind of “gridlock” that ensues when a computation stalls because no new tasks are eligible f...

This paper explains concepts underlying a just-in-time production system. Just-in-time production systems as implemented by Toyota are pull systems in which ‘kanban’ convey the need to replenish the right inventory at the right time and in the right amount. In this paper, symbols from manufacturing are introduced to map resource flows in order to help distinguish traditionalfrom lean production...

Range Minimum Query (RMQ) is an important building brick of many compressed data structures and string matching algorithms. Although this problem is essentially solved in theory, with sophisticated data structures allowing for constant time queries, there are scenarios in which the number of queries, q, is rather small and given beforehand, which encourages to use a simpler approach. A recent w...

Motivated by practical applications, chiefly clinical trials, we study the regret achievable for stochastic bandits under the constraint that the employed policy must split trials into a small number of batches. We propose a simple policy, and show that a very small number of batches gives close to minimax optimal regret bounds. As a byproduct, we derive optimal policies with low switching cost...

Queries, or calls to stored procedures/user-defined functions are often invoked multiple times, either from within a loop in an application program, or from the where/select clause of an outer query. When the invoked query/procedure/function involves database access, a naive implementation can result in very poor performance, due to random I/O. Query decorrelation addresses this problem in the ...

background and objectives: while social network analysis has left a remarkable practical impact in the healthcare field, the potential implication of this methodology in the primary health domain is poorly researched. hence, this study aimed to explore the use and usefulness social network analysis in the context of primary health care. methods: the health volunteers of imam ali health center i...
