Abstract—Belt conveyors play an important role in continuous dry bulk material transport, especially at the mining industry. Speed control is expected to reduce the energy consumption of belt conveyors. Transient operation is the operation of increasing or decreasing conveyor speed for speed control. According to literature review, current research rarely takes the conveyor dynamics in transien...

In this paper, we extend the notions of γ-operation introduced in [12], by using the soft ideal notions. We introduce the notions of Ĩ-open soft sets, pre-Ĩopen soft sets, α-Ĩ-open soft sets, semi-Ĩ-open soft sets and β-Ĩ-open soft sets to soft topological spaces. We study the relations between these different types of subsets of soft topological spaces with soft ideal. We also introduce the co...

The main purpose of this paper is to clarify some important links between regional cooperation, (soft) infrastructure and trading costs, and to suggest some hypotheses for further investigation. Khan and Weiss(2006) discuss the issue of both hard and soft infrastructure in this context. This paper is a continuation of Khan and Weiss(2006) but in the specific context of soft infrastructure, and ...

The boost topology is the most popular topology used in power factor correction circuits. The efficiency and performance of the boost converter depends on the switching frequency affecting the switching losses. At high frequency operations the switching losses of the converter is considerable and decreases the efficiency of the converter. To remove this problem the converter is designed to oper...

The goal of Combinatorial Optimization is finding the best possible solution from the set of feasible solutions. This can be solved using either Artificial Intelligence or Operation Research. Timetabling means scheduling activities to time slots in an order by satisfying hard constraints and soft constraints. Hard constraints should be satisfied but the violations of soft constraints to be mini...
