R is called commuting regular ring (resp. semigroup) if for each x,y $in$ R there exists a $in$ R such that xy = yxayx. In this paper, we introduce the concept of commuting $pi$-regular rings (resp. semigroups) and study various properties of them.

PURPOSE The purpose of this study was to assess the level of patient satisfaction and associated factors with psychiatric outpatient services in Ethiopia.

Engaging in regular physical activity is a challenging task for many adults. Intrinsic satisfaction with exercise classes is thought to promote adherence to physical activity. This study examined the characteristics of exercise classes that impact within-person changes in intrinsic satisfaction over the course of an extended group exercise program. A 30-week physical activity trial was conducte...

Symbolic automata theory lifts classical automata theory to rich alphabet theories. It does so by replacing an explicit alphabet with an alphabet described implicitly by a Boolean algebra. How does this lifting affect the basic algorithms that lay the foundation for modern automata theory and what is the incentive for doing this? We investigate these questions here. In our approach we use state...

The objective of partial satisfaction planning is to achieve an as valuable as possible state, tacking into account the cost of its achievement. In this work we investigate the computational complexity of restricted fragments of two variants of partial satisfaction: net-benefit and oversubscription planning. In particular, we examine restrictions on the causal graph structure and variable domai...

We consider the navigation problem of a robot from a starting point S to a target point T inside an unknown rectilinear polygon. The robot knows the directions of the points S and T and it can detect the edges of the polygon through its tactile sensors. We present a competitive strategy for the robot to reach the target T . The competitive ratio of our strategy is 6 4:5dðj 1Þðjþ 2Þ þOð1Þ, where...

Abstract Strings are ubiquitous in software. Tools for verification and testing of software rely in various degrees on reasoning about strings. Web applications are particularly important in this context since they tend to be string-heavy and have large number security errors attributable to improper string sanitzation and manipulations. In recent years, many string solvers have been implemente...
