we consider biobjective shortest path problems in networks with fuzzy arc lengths. considering the available studies for single objective shortest path problems in fuzzy networks, using a distance function for comparison of fuzzy numbers, we propose three approaches for solving the biobjective prob- lems. the rst and second approaches are extensions of the labeling method to solve the sing...

A family $\mathcal{P}$ of subgraphs $G$ is called a path cover (resp. partition) if $\bigcup _{P\in \mathcal{P}}V(P)=V(G)$ $\dot\bigcup \mathcal{P}}V(P)=V(G)$) and every element path. The minimum cardinality denoted by ${\rm pc}(G)$ pp}(G)$). In this paper, we characterize the forbidden subgraph conditions assuring us that (or pp}(G)$) bounded constant. Our main results introduce new Ramsey-typ...

this paper develops an automatic parking algorithm based on a fuzzy logic controller with the vehicle pose for the input and the steering angle for the output. in this way some feasible reference trajectory path have been introduced according to geometric and kinematic constraints and nonholonomic constraints to simulate motion path of car. also a novel method is used for parking space detectio...

being on the right paththe 1st issue of the iranian journal of radiation research (ijrr) was published two years ago (june 2003). this journal was initiated to bring together the various disciplines of radiation oncology, radiation biology, medical physics, nuclear medicine and other related subjects to intensify the dialogue between basic and clinical researchers especially those working in ir...

fluctuation of exchange rate and its deviation from equilibrium path are one of the most important macroeconomic variables that is affected by different side of economical sectors. whereas, the exchange rate fluctuation and its deviation from equilibrium path haven’t the same and similar effects on all of the economical sectors, and considering eminent important of industrial development on the...
