mobile robot navigation is one of the basic problems in robotics. in this paper, a new approachis proposed for autonomous mobile robot navigation in an unknown environment. the proposedapproach is based on learning virtual parallel paths that propel the mobile robot toward the trackusing a multi-layer, feed-forward neural network. for training, a human operator navigates themobile robot in some...

The aim of this research paper is to formulate a road map for implementation of lean techniques within SMEs product development (PD) teams, identifying barriers to change and explaining possible drivers for successful implementation. The research methodology necessary to develop the road map – the IPID cycle – is a combination of different approaches. It combines a literature review, an initial...

the rapid and uncontrolled growth of tourism, that has influenced the economic foundations of rural economy, has caused different economic impacts and consequences in the rural areas of the central district of the city of nowshahr. the purpose of this study is to recognize and analyze the impacts of tourism in this area based on the principles of sustainable tourism and relevant theoretical bas...

in this paper, a new hardware implementation for the real time disparity map is presented. The real time disparity map includes the Dynamic Search Range Estimation, Disparity estimation, and Error Correction. Our demonstrated design flow shows an approach to implementation and hardware architecture of real-time disparity map estimation. This design is efficiently synthesized on Xilinx vertex 4 ...

Presented are the investigations showing an impact of the length of data signals in hardware implemented Kohonen Self-Organizing Maps (SOM) on the quality of the learning process. The aim of this work was to determine the allowable reduction of the number of bits in particular signals that does not deteriorate the network behavior. The efficiency of the learning process has been quantified by u...

The Microwave Anisotropy Probe (MAP) satellite, launched June 30, 2001, will produce full sky maps of the cosmic microwave background radiation in 5 frequency bands spanning 20 106 GHz. MAP contains 20 differential radiometers built with High Electron Mobility Transistor (HEMT) amplifiers with passively cooled input stages. The design and test techniques used to evaluate and minimize systematic...
