abstract cooperative learning refers to small groups of learners working together as a team to solve a problem, complete a task, or accomplish a common goal. in a cooperative environment one’s success is directly related to the success of other members because the focus on the individual shifts towards the group. to test the effectiveness of the method, using jigsaw technique, a study was cond...

This paper presents the stochastic analysis of a two unit parallel system model with the concept of correlation between time to preventive maintenance and preventive maintenance time. The joint distribution of time to preventive maintenance and preventive maintenance time is taken bivariate exponential. Using regenerative point technique, various measures of system effectiveness useful to syste...

Historically, research has shown that it is neither physically possible nor economically feasible to construct an asphalt concrete pavement surface that provides skid resistance at an adequate level throughout the pavement's service life. Consequently, engineers utilize a seal coat maintenance technique as one way of improving friction performance on roadways. This maintenance technique consist...

Shared mutable state is challenging to maintain in a distributed environment. We develop a technique, based on the Operational Transform, that guides independent agents into producing consistent states through inconsistent but equivalent histories of operations. Our technique, history maintenance, extends and streamlines the Operational Transform for general distributed systems. We describe how...

Maintenance of water distribution systems is becoming a critical infrastructure problem. Good maintenance practices are necessary to extend the life of water distribution system components and an optimal maintenance effort can further prolong their useful life. The decision making problem of determining the best maintenance strategy which would minimize the total discounted maintenance cost ove...

This paper investigates the integrated production and imperfect preventive maintenance planning problem. The main objective is to determine an optimal combined production and maintenance strategy that concurrently minimizes production as well as maintenance costs during a given finite planning horizon. To enhance the quality of the solution and improve the computational time, we reconsider the ...

Views stored in a data warehouse need to be kept current. As recomputing the views is very expensive, incremental maintenance algorithms are required. Over recent years, several incremental maintenance algorithms have been proposed. None of the proposed algorithms handle the general case of relational expressions involving aggregate and outerjoin operators efficiently. In this article, we devel...
