A robot path planning technique is proposed in the paper. It was developed for robots with differential drive, but with minor modifications it could be used for all types of nonholonomic robots. The path was planned in the way to minimise the time of reaching the end point in desired direction and with desired velocity, starting from the initial state described by the start point, initial direc...

Despite widespread availability of and knowledge about contraception in the USA, nearly half of all pregnancies are unintended.1 Recent evidence suggests that many women are ambivalent about avoiding or trying for pregnancy.2 With ambivalence about getting pregnant linked to inconsistent contraceptive use,3 scholars have called for greater understanding of the complex dimensions of pregnancy in...

Connection of distributed generation (DG) units, energy storages, and new loads into low voltage (LV) grids leads to a constrained operation of the grids. Consequently, voltage limits violation and overloading of grid assets occur more frequently. To tackle these issues, distribution system operators (DSO) still employ traditional techniques in planning distribution grids to increase grid hosti...

We begin by looking a t the central role of reasoning about change in planning and control. We then review some of the basic insights of control theory regarding the connection between observability and controllability, and consider how these insights should inform research in planning. We propose a decision-theoretic approach to planning that subscribes to a basic cycle of prediction, observat...

today, ecotourism is a major tourist activity around the world. it is based on environment potential through which suitable utilization and conservation of sites under management practices including considering accurate planning, potential, and peoples’ preferences are realized. the present study was conducted to determine people’s recreational preferences using questionnaires to evaluate the e...

Considering the benefits of preparation for writing in the pre-writing phase, this study attempted to examine the effects of different pre-task strategic planning activities (i.e., pre-task form-focus planning, content-focus planning, and no planning) on writing accuracy and motivation. To achieve the objectives of this study, sixty intermediate EFL learners were selected from an English langua...

The conventional maximum torque per ampere (MTPA) operation usually neglects the derivative terms of interior permanent magnet synchronous motor (IPMSM) parameters, which significantly influences MTPA control accuracy. In this study, an scheme that considers is developed, and a parameter identification strategy inverter to be non-ideal developed for calculation IPMSM parameters terms. addition,...
