Abstract Industrial equipment/machinery is an important element of manufacturing. They are used for producing objects that people need everyday use. Therefore, there a challenge to adopt effective maintenance strategies keep them well-functioning and well-maintained in production lines. This will save energy materials contribute genuinely the circular economy creating value. Remanufacturing or ...

The intention of this work is to eliminate the need for a synchronous generation scheme in the (μ +, λ) evolution strategy. It is motivated by the need for a more practical implementation of selection strategies on parallel machine architectures. This strategy is known as continuous or steady state selection. Continuous selection is known to reduce significantly the number of function evaluatio...

Gas condensate reservoirs are characterized by a distinctive retrograde behavior and potential for condensate drop out during production and sampling. Efficient modeling of gas condensate reservoir requires careful phase behavior studies of samples collected prior to and during the production life of reservoir. In this work, an integrated characterization and tuning algorithm is proposed to ana...

Artificial Neural Networks (ANN) comprise important symmetry properties, which can influence the performance of Monte Carlo methods in Neuroevolution. The problem of the symmetries is also known as the competing conventions problem or simply as the permutation problem. In the literature, symmetries are mainly addressed in Genetic Algoritm based approaches. However, investigations in this direct...

The present study investigated four different filtering and differentiation sequences for the calculation of the higher derivatives from noisy displacement data when using a second-order Butterworth filter and first-order finite differences. These were: (1) the conventional sequence (i.e. filtering the displacement data and then differentiating); (2) filtering the displacement with a different ...

Assuming perfect channel state information at the transmitter of a Gaussian broadcast channel, strategies are investigated on how to assign subchannels in frequency and space domain to each receiver aiming at a maximization of the sum rate transmitted over the channel. For the general sum capacity maximizing solution, which has recently been found, a method is proposed that transforms each of t...

A sample of 331 residents of Grapevine, Texas, responded to an instrument designed to assess their perspectives of the priority issues related to economic development in their community. The instrument also assessed the parks and recreation department’s contributions to these issues, and compared them with those of the police department in the area of preventing youth crime. The data were used ...

In order to supply optimum water to restore reed wetlands used for bird habitats, a field investigation and greenhouse experiment were conducted. Three water supplementation stages (early stage at 20 May, middle stage at 20 July and later stage at 20 September, respectively) and five depths (0, 10, 15, 20 and 35 cm over the surface, respectively) were established, with three replicates for each...

In this paper, an analytical approach is used for assembly line rebalancing and worker assignment for single and mixed-model assembly lines based on a heuristic-simulation algorithm. This approach helps to managers to select a better marketing strategy when different combinations of demands are suitable.Furthermore, they can use it as a guideline to know which worker assignment is better for ea...

A distributed wireless network with K links is considered, where the links are partitioned into M clusters each operating in a subchannel with bandwidth W/M. The subchannels are assumed to be orthogonal to each other. A general shadow-fading model described by the probability of shadowing α and the average cross-link gains ≤ 1 is considered. The main goal is to find the maximum network throughp...
