During 1990 and 1991 we carried out a survey of Z users in the UK; in this paper we present the results. Z is being used by a wide variety of companies for many different applications. Many institutions use Z because they choose to, rather than because it is mandated by a defence or security related client. Half of the participants in the survey were first-time users of Z; with a little trainin...

In the IEEE 802.16e system, we propose an efficient power saving mechanism that increases the unavailability interval when the mobile station (MS) uses multiple power saving classes(PSCs). Through the simulation results, we show that the proposed mechanism reduces the power consumption of MSs considerably compared with conventional mechanism.

Tomato (Lycopersicon esculentum) most produced and marketed fruit in the world has high market potentiality Nepal too because of its versatility use as salad, vegetable, pickle raw material forr processing industry nutrient factors with huge health benefits. In recent decades off season tomato have good demand price at both national international level which is attracting great number farmers f...

It is of crucial importance the integration of practical sessions in engineering curricula owing to their significant role in understanding engineering concepts and scientific phenomena. However, the lack of practical sessions due to the high costs of the equipment and the unavailability of instructors has caused a significant declination in experimentation in engineering education. Remote labo...

To operate in dynamic environments robots must be able to adapt their behaviour to meet the challenges that these pose while being constrained by their physical and computational limitation. In this paper we continue our study into using biologically inspired epigenetic adaptation through hormone modulation as a way to accommodate the needed flexibility in robots’ behaviour, focusing on problem...

Opinion Mining is a topic which attracted a lot of interest in the last years. By observing the literature, it is often hard to replicate system evaluation due to the unavailability of the data used for the evaluation or to the lack of details about the protocol used in the campaign. In this paper, we propose an evaluation protocol, called DRANZIERA, composed of a multi-domain dataset and guide...

This paper aims at discussing the realization of some Brazilian Sign Language signs, articulated with both hands, when one of them is unavailable. As will be discussed, this unavailability is caused by extra-linguistic factors, as well as by a linguistic one. The data considered here were collected through the observation of spontaneous signing and discussed with three subjects. Their analysis ...

Although unavailability and failure frequency are both important reliability measures for designing telecommunications networks, having two different reliability measures causes difficulties when their evaluation results contradict each other. To overcome these difficulties, I propose an approach to determining a single reliability measure to be used. I focus on market share, which is a very im...

In single machine scheduling problems with availability constraints, machines are not available for one or more periods of time. In this paper, we consider a single machine scheduling problem with flexible and periodic availability constraints. In this problem, the maximum continuous working time for each machine increases in a stepwise manner with two different values allowed. Also, the durati...
