Sugar cane growers in Puerto Rico are faced with problems of weed control as any other farmer in the world. He is faced with increased cost of production of cane, through higher labor and material costs. When labor costs were low, much of the weed control was done by many men using machetes and other implements. As every farmer knows "weeds are plants out of place." Since beginning of farming, ...

Abstract In this paper, the hyperchaos analysis, optimal control, and synchronization of a nonautonomous cardiac conduction system are investigated. We mainly analyze, synchronize associated hyperchaotic behaviors using several approaches. More specifically, related nonlinear mathematical model is firstly introduced in forms both integer- fractional-order differential equations. Then attractors...

social media is being notably used these days. This has reflected in a sort of coercion known as cyberbullying. Bullies use vivid community spots to assault victims with obnoxious Feedback and posts. been so ruinous that numerous youngsters suffer despair, commit self-murder, lose their tone confidence, plenty less. With obscurity deficit Supervision this form bullying advanced exponentially. I...

An annulus is, informally, a ring-shaped region, often described by two concentric circles. The maximum-width empty problem asks to find an of certain shape with the maximum possible width that avoids given set n points in plane. This can also be interpreted as finding optimal location obnoxious facility among input points. In this paper, we study square and rectangular variants problem, presen...

The general acceptance of the unsentenced prisoner's right to medical treatmentl.~ will result in physicians' diagnosing and treating more patients from a segment of the population which, until recently, was relatively neglected. Since it will not be feasible to establish comprehensive medical services in each jail, it is likely that referrals will be made to general hospitals and that more inm...

An antimedian of a profile π = (x1, x2, . . . , xk) of vertices of a graph G is a vertex maximizing the sum of the distances to the elements of the profile. The antimedian function is defined on the set of all profiles on G and has as output the set of antimedians of a profile. It is a typical location function for finding a location for an obnoxious facility. The ‘converse’ of the antimedian f...

semi-regular locales are extensions of the classical semiregularspaces. we investigate the conditions such that semi-regularizationis a functor. we also investigate the conditions such that semi-regularizationis a reflection or coreflection.

This study examines the various conflicting issues between and among public service agencies to enhance Nigeria's effective security delivery. While embraces use of a systems approach, it adopts conceptual review approach with pictorial evidence critical extant literature discuss intra- inter-sectional conflict in Nigerian delivery system. The findings show, that superior complexities personnel...
