literature review indicates that systemic agricultural human resource development (hrd) interventions are rarely carried out in developing countries, and limited knowledge exists about how successful they have been. a comparative study was carried out to investigate the effectiveness of three multi-project hrd interventions including extension plans, adaptation plans and diffusion-push plans in...

literature review indicates that systemic agricultural human resource development interventions are rarely carried out in developing countries, and limited knowledge exists about how successful they are. learning transfer is the generalization of material learned, such as skills acquired or knowledge gained in training, back to the job. the main aim of this study was to analyze factors influenc...

one of the indicators for evaluating the effectiveness of farmers’ training is the transfer of learning by them. the aim of current study was to investigate factors influencing the implementation of the recommendations of research finding diffusion-push plans by farmers. research population consisted of farmers who participated at least in one of the research finding diffusion-push plans in far...

Majority of the methods proposed for the problem of push planning and manipulation deal with objects that have quasistatic properties and primitive geometric shapes, yet they usually use complex physics modeling for the manipulated object as well as the manipulator. Our proposed approach is an experience-based one, where the mobile robot experiments with pushable complex real world objects to o...

Planning with sensing actions under partial observability is a computationally challenging problem that is fundamental to the realization of AI tasks in areas as diverse as robotics, game playing, and diagnostic problem solving. Recent work on generating plans for partially observable domains has advocated for online planning, claiming that offline plans are often too large to generate. Here we...

In existing relational database systems, processing of group-by and computation of aggregate functions are always postponed until all joins are performed. In this paper, we present transformations that make it possible to push group-by operation past one or more joins and can potentially reduce the cost of processing a query significantly. Therefore, the placement of group-by should be decided ...

We present an experience-based pushmanipulation method, where the mobile robot learns through experimentation how the pushable real world objects with complex 3D structures move in response to various pushing actions. These experimentally acquired models are then used as building blocks for constructing achievable push plans via a Rapidly-exploring Random Trees variant planning algorithm we con...

In this paper we propose system architecture and implementation methodology of walking assistant robot for the elderly. We use shared control system based on sensor feedback. For operation user push or pull handle, than robot sense applied force. It decides velocity and direction of the robot. If obstacles are detected, robot avoids obstacles and plans new path for collision free. It can provid...

I. OVERVIEW We contribute an algorithm that utilizes the observed effects of previously experimented and memorized pushing moves to generate achievable push plans for passive mobile objects (http://youtu.be/V2gf39mYepI). The most common scenarios in the push planning literature are pushing of a disk or box shaped quasi-static object with a smaller disk shaped or even point-sized robot, and the ...
