To demonstrate the robustness of extraction systems against radiolytic degradation is nowadays one of the limiting points to ensure a safe and stable operation for advanced nuclear fuel strategies. In this paper, is addressed the stability of one of most promising extra...

Abstract Distillation is a largely used separation operation, but at the same time it is intensively energy consuming. Distillation columns need huge amount of energy due to evaporation steps involved; more than half of the process heat distributed to plant operations e...

Logistics can be seen as the compound of all the considerations needed to ensure the efficient and economical support of a system throughout its life cycle. The unscheduled actions, performed as a result of a failure or a perceived failure, that are necessary to restore...

Abstract Visual rehabilitation therapy is one of the most problematic issue in stroke rehabilitation. The difficulties consist in specific assessment of visual deficit and poor results reports by the authors of the clinical studies. Opposite, experimental studies report...

We start from the kinematic scheme of a mechanism with three dyads, all of the RRR type connected in this way: the first dyad to the driving element R and to the base, the second dyad to the connecting rod of the first dyad in the mechanism and to its rocker, and the th...

Headway fluctuations and “bus bunching” are well known phenomena on many bus routes where an initial delay to one service can disturb the whole schedule due to resulting differences in dwell times of subsequent buses at stops. This paper deals with the influence of a fr...

Gears are part of everyday experience from very early childhood. This paper analyses a teaching experiment conducted with 4th graders in the field of experience of gears. The aim is to identify the characteristics which, given a suitable sequence of tasks and proper tea...

In the specialized literature the cost of the machining process has been analyzed using a number of approaches and varying degrees of simplification to determine the optimum tool life and the tool speed. The accuracy of prediction is dependent on the degree of sophistic...

When controlling industrial processes, setpoint tracking and disturbance rejection play an important part in the design and tuning of the PID controller parameters, especially since most of these processes exhibit dead-times. Internal Model Control (IMC) algorithms have...

Background: Identification of epidemiological particularities at patients with HIV/AIDS out of a specific geographic zone permits defining groups of risk for this disease, early diagnosis and applying the methods of prevention and prophylaxis. Methods: The authors have ...
