The objective of this paper is to enable CCD camera for area measuring while recording images simultaneously. Based on an established relationship between pixel number and distance in this paper, we can derive the horizontal and vertical length of a targeted object, and subsequently calculate the area covered by the object. Because of the advantages demonstrated, the proposed system can be used...

This paper analyzes MIMO propagation channels for personal area networks. Such channels show important differences to propagation channels in wide-area networks, due to the different environments in which the systems are operated, as well as due to different mobility models, ranges, and presence of humans in the environment, and the impact of the antenna arrangement. We present results from a r...

We are interested in the problem of how a mobile robot can measure the area of a closed region that is beyond its immediate sensing range. Our inspiration comes from scout worker ants who assess potential nest cavities. These scouts work literally in dark to assess arbitrary closed spaces. Experimental studies have shown that the scouts can reliably reject nest sites that are small for the colo...

‏‎applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...

Proper judgement on rangeland state needs appropriate sampling plan and accurately estimation of plant characteristics. Sample shape and size are critical issues in vegetation measurement. Thus, decision on appropriate quadrate shape that enables us to determine several parameters accurately and timely would increase sampling efficiency. Several criterias including accuracy, perimeter/area rati...
