Transmission network expansion planning (TNEP) is an important component of power system planning that its task is to minimize the network construction and operational cost while satisfying the demand increasing, imposed technical and economic conditions. Up till now, various methods have been presented to solve the static transmission network expansion planning (STNEP) problem. But in all of t...

In a wavelength division multiplexed (WDM) network, each fiber link carries high-rate data on several different wavelengths, thus creating multiple channels within a single fiber. The most common architecture utilized for establishing communication in WDM optical networks is wavelength routing, where optical pulse trains are transmitted through lightpaths, that is, all-optical WDM channels that...

Nowadays, a significant number of distribution systems are facing problems to accommodate more photovoltaic (PV) capacity, namely due to the overvoltages during the daylight periods. This has an impact on the private investments in distributed energy resources (DER), since it occurs exactly when the PV prices are becoming attractive, and the opportunity to an energy transition based on solar te...

This paper concerns on footstep planning of a biped robot in an environment having some obstacles. Biped robot has an advantage to work in human surroundings: This is accomplished by its capability to walk over the obstacles. Though its foot placement should be discussed to step over obstacles, it is difficult because dynamic biped locomotion is a complex interaction system between CoG trajecto...

This paper presents a novel mathematical model for the transmission network expansion planning problem. Main idea is to consider phase-shifter (PS) transformers as a new element of the transmission system expansion together with other traditional components such as transmission lines and conventional transformers. In this way, PS are added in order to redistribute active power flows in the syst...

Trajectory (path) planning is a well known and thoroughly studied field of automated planning. It is usually used in computer games, robotics or autonomous agent simulations. Grids are often used for regular discretization of continuous space. Many methods exist for trajectory (path) planning on grids, we address the well known A* algorithm and the state-of-the-art Theta* algorithm. Theta* algo...

This paper describes a motion planning method for mobile robot which considers the path ambiguity of moving obstacles. Each moving obstacle has a set of paths and their probabilities. The robot selects the motion which minimizes the expected time to reach its destination, by recursively predicting future states of each obstacle and then selecting the best motion for them. To calculate the motio...

Aggregate Production Planning (APP) is a medium-term planning which is concerned with the lowest-cost method of production planning to meet customers’ requirements and to satisfy fluctuating demand over a planning time horizon. APP problem has been studied widely since it was introduced and formulated in 1950s. However, in several conducted studies in the APP area, most of the researchers have ...

The restructuring of global power industries has introduced a number of challenges, such as conflicting planning objectives and increasing uncertainties, to transmission network planners. During the recent past, a number of distributed generation technologies also reached a stage allowing large scale implementation, which will profoundly influence the power industry, as well as the practice of ...

This paper summarizes initial work on a planetary rover planning domain where long-distance traverse, large-scale terrain, changing line-of-sight geometry, finite resources and time strongly affect the strategy for achieving mission objectives. In this domain, because path planning, activity scheduling and resource usage are closely coupled, they must be considered simultaneously. We introduce ...
