The fact that real-world decisions made by artificial intelligences (AI) are often ethically loaded has led a number of authorities to advocate the development “moral machines”. I argue project building “ethics” “into” machines presupposes flawed understanding nature ethics. Drawing on work Australian philosopher, Raimond Gaita, ethical dilemmas problems for particular people and not (just) eve...

Since the development of space based geodesic techniques, the increasing of the positioning accuracy has been a major goal. In this context, the effect of the ionosphere has been a key issue to be taken into account to improve the navigation results obtained using several types of receivers: from dual frequency phase receivers at distances greater than tens of kilometres of the nearest fixed si...

Abstract Reciprocity guarantees that in most media, sound transmission is symmetric between two points of space when the location source and receiver are interchanged. This fundamental law can be broken non-linear often at cost detrimental input power levels, large insertion losses, ideally prepared single-frequency signals. Thus, previous observations non-reciprocal have focused on pure tones,...

In this paper, we investigate the performance of transmit diversity technique operating in IS-136 T D M A systems where the Doppler frequency can be as high as 184Hz. Transmit diversity transforms a pat fading channel into a frequency selective fading channel, thus we use finite length decision feedback equalizers to estimate the desired signal at the receiver. The channel parameters are traine...

A narrowband mobile communication systems is proposed in this paper. The interference cancellation is achieved by the projection receiver. Our study is concentrated on a dual-antenna system, including performance analysis and simulations. The e ects of delay, phase bias and frequency o set are considered. A blind receiver is also proposed and simulated for this system.

?ima?ki is one of the important toponyms in old elamite period. until now, there has been no agreement among archaeologists on the location of this toponym. this article wants to show why the kerman province cannot be the good candidate for this toponym. for this purpose, the authors used the archaeological and written documents. an important integrative analysis of archaeological survey data w...

We investigate the issue of distributed receiver cooperation in a multiple-relay network with memoryless independent fading channels, where the channel state information can’t be obtained. The received signals at distributed receiving nodes are first compressed or quantized before being sent to the decoder via rate-limited cooperation channels for joint processing. We focus on the low SNR regim...
