This article summarizes VIAC, the VisLab Intercontinental Autonomous Challenge, a test of autonomous driving from Italy to China using four electric vehicles. The vehicles were equipped with a complete sensorial suite that involved different kinds of sensors like cameras, laser scanners, GPS, and others; they feature autonomous capabilities thanks to a x-by-wire subsystem able to control the st...

Single staggered is a design development of normal wire and tube heat exchanger that wires are welded with staggered configuration on two sides. Capacity of wire and tube heat exchanger is the ability of the heat exchanger to release heat. The objective of this study is to analyse the effect of wire pitch (pw) on capacity of single staggered wire and tube heat exchanger. The research...

In this research, the behavior and characteristics of the wake of flow in an elliptic cylinder with zero angle of attack in the presence of a tripping wire were investigated experimentally. For this purpose, the used an Aluminum cylinder with an elliptical cross section of the major and minor axis of 42.4 mm and 21.2 mm, respectively, and of the height of 390 mm. The cylinder model was examined...

This paper addresses the problem of characterizing analytically the autocorrelation structure of TCP traffic. We show that, under simple models, a single TCP connection generates traffic with an exponentially decreasing autocorrelation function. However, several TCP connections sharing a given link can generate traffic with long term dependencies, under the condition that the distribution of th...

Photovoltaic arc faults have led to a number of rooftop fires that have caused significant property damage and threatened the safety of building occupants. In response, Article 690.11 was added to the United States 2011 National Electrical Code, requiring new PV systems on or penetrating a building to include a listed arc fault protection device. Many proposed arc fault detectors utilize freque...

This research elucidates the trip pattern of the low-density residential zone in a semi-urban industrial cluster of southwestern Nigeria. These sets of dwellers are often times neglected in the transportation planning process with the view that it is not a residential zone. Domiciliary information gathering procedure was employed in the analysis with 0.82 return rates. It was backed up with the...

In this article, an innovative supervision system will be proposed that can observe and analyze health of Circuit Breaker’s trip coil. The proposed design also logs changes in the coil's quality and informs network supervisor in case of Circuit Breaker (CB) failure. This system injects small direct currents to the Circuit Breaker connections and the trip coil to compute CB’s health and characte...

This paper considers the popular but questionable technique of ‘round-trip translation’ (RTT) as a means of evaluating free on-line Machine Translation systems. Two experiments are reported, both relating to common requirements of lay-users of MT on the web. In the first we see whether RTT can accurately predict the overall quality of the MT system. In the second, we ask whether RTT can predict...
