We put forth in this paper a geometrically motivated 3-D motion error analysis which is capable of supporting investigation of global effect such as inherent ambiguities. The error expression that we derive allows us to predict the exact conditions likely to cause ambiguities and how these ambiguities vary with motion types such as lateral or forward motion. Our formulation, though geometricall...

This paper proposes a technique for planar trajectory following for an autonomous aerial robot. A trajectory is modeled as a planar spline. A behavior-based control system which stabilizes the robot and enforces trajec-tory following, has been implemented and tested on an autonomous helicopter. Results from two ight experiments are presented. The trajectory tracking error is on the order of the...

In science generally, the analysis of the errors inherent in continuous-scaled measurements of quantities is well developed, and numerous textbooks are available (e.g., Taylor, 1982). It is possible, for example, to predict the errors that result when individual measurements are combined arithmetically, based on differentiation of the combination equation with respect to the measurements, and b...

Many archaeologists still rely predominately on string, line level, tape measure, pen and paper to draw floor plans and profile walls. This is a time consuming and labor intensive process that can suffer greatly from human error. This paper describes a software system for generating archaeological floor plans and profile walls that minimizes the error inherent in traditional methods and reduces...

One inherent problem of network video is the sensitivity of the compressed bit-stream to data loss. Since block motion compensation is widely adopted in present day video coding standards, any damage to these compressed video bitstreams may lead to degradation of video quality due to error propagation and accumulation. This paper introduces a new scheme for robust coding and transmission of vid...

Iterative processing for linear matrix channels, aka turbo equalization, turbo demodulation, or turbo CDMA, has traditionally been studied as the concatenation of conventional error control codes with the linear (matrix) channel. However, in several situation, such as CDMA, the channel itself contains inherent redundancy, such as a repetition code contained in the direct-spread signature sequen...

While both Mendelssohn and Rousseau were deeply spiritual thinkers whose writings continually reflect a profound belief in benevolent God, they still used religious skepticism order to undermine the logic of intolerance. In doing so, these critical assumption share with far less religiously inclined David Hume, namely, that is tool for promotion tolerance. This paper analyses skeptical tolerant...

-An artificial network is described that can learn, recognize, and generate higher-order temporalspatial sequences. It consists of three parts: (1) comparator units, (2) a parallel array of artificial neural networks that are derived from the visual-vestibular networks of the snail Hermissenda. as well as hippocampal neuroanatomy, and (3) delayed feedback lines from the output of the system to ...

This paper examines the morality of schemes of payment to live donors/sellers of organs for transplantation. Following empirical and historical evidence, it is argued that consent to sell organs is substantially different from consent to ordinary business transactions and that legalization of exchanges of organs with financial benefits deviates significantly from the scope of liberal toleration...
