Wireless communication devices are often battery-powered. Reducing energy consumption during transmission has become a major challenge. We propose an optimal adaptation scheme and a suboptimal scheme based on the continuous-power discrete-rate adaptation (CPDR) for energy efficient transmission over fading channels. In our proposed schemes, we optimize the average transmit power according to data rate of the source node and buffer level, and then we adapt the transmit rate and power according to the CPDR scheme. Simulation results show that our proposed schemes have outstanding performance on

AbstractCoincidence Analysis (CNA) is a configurational comparative method of causal data analysis that is related to Qualitative Comparative Analysis (QCA) but, contrary to the latter, is custom-built for analyzing causal structures with multiple outcomes. So far, however, CNA has only been capable of processing dichotomous variables, which greatly limited its scope of applicability. This paper generalizes CNA for multi-value variables as well as continuous variables whose values are interpreted as membership scores in fuzzy sets. This generalization comes with a major adaptation of CNA’s alg

According to objective literature, in each of the foregoing areas of law, the term “document” has a different precision in the content used to perform a particular function, in order to obtain a certain probative and legislative power. Despite the extensive scope of the concept of civil and legal “document”, the legislature does not limit its semantic domain. The legal status created by the legislator allows for the adaptation of the term “document”, to the new terms used by the legislature in the definition of legal and regu- latory acts.The theoretical and broad interpretation of the term “d

A substantial number of off-grid olive oil mills in Morocco are powered by diesel-fired generators, which hugely contribute to air pollution and greenhouse gas emissions. In this research work, a biomass gasification combined heat and power (CHP) plant fueled with local by-products was explored as a renewable alternative to electrify off-grid olive oil mills in this country. The case study considered a gasification CHP plant with a rated power of 80 kWe, in order to enable adaptation of the producer gas flow rate to abrupt changes in the power generation unit under dynamic operation.

Abstract Supply chain collaboration is one of the most crucial variables of driving business success in organic fertiliser Companies, especially to maintain the continual flow from upstream to downstream. Therefore, understanding the level of collaboration factors is vital in sustaining the partnership as well as reducing any conflicts among stakeholders. This study aims to measure the depth of collaboration among Company X and its suppliers. The assessment of the supply chain collaboration index will perform Fuzzy Analytical Hierarchy Process (FAHP) to weight the collaboration behaviour facto

Abstract. The sensing characteristics and long-term stability of different kinds of CO ∕ HC gas sensors (non-Nernstian mixed potential type) during in situ operation in flue gas from different types of low-power combustion systems (wood-log- and wood-chip-fuelled) were investigated. The sensors showed representative but individual sensing behaviour with respect to characteristically varying flue gas composition over the combustion process. The long-term sensor signal stability evaluated by repeated exposure to CO ∕ H2 ∕ N2 ∕ synthetic air mixtures showed no sensitivity loss after operation in

This study aimed to assess the acute effects of moderate- and higher-intensity exercise on endothelial function, as assessed by flow-mediated dilation (FMD), in AAA patients (74 ± 6 yr old, n = 22) and healthy adults (72 ± 5 yr old, n = 22). Participants undertook three randomized visits, including moderate-intensity continuous exercise [40% peak power output (PPO)], higher-intensity interval exercise (70% PPO), and a no-exercise control.

Then, the problems of biotechnology, digitalization and immigration are examined, which reaffirm the dominant importance of realism in an interesting way. The author illustrates with a series of exa

The existence of a continuous array of sympatric biotypes—from polymorphisms, through ecological or host races with increasing reproductive isolation, to good species—can provide strong evidence for a continuous route to sympatric speciation via natural selection. Host races in plant–feeding insects, in particular, have often been used as evidence for the probability of sympatric speciation. Here, we provide verifiable criteria to distinguish host races from other biotypes: in brief, host races are genetically differentiated, sympatric populations of parasites that use different hosts and betw

Although, most existing algorithms have poor applicability in dealing with this problem, especially in the multi-objective optimization operation of reservoirs with unknown Pareto fronts. Therefore, this paper introduces an evolutionary algorithm with strong versatility and robustness named the Multi-Objective Evolutionary Algorithm with Reference Point Adaptation (AR-MOEA).

Unlike standard interval training, this particular type of interval training does not include passive rest periods but combines high-intensity training with low-intensity recovery periods. The aims of the study were to determine the effect of aerobic power training implemented in the form of interval training with active recovery on the physical capacity of amateur long-distance runners as well as

The article discusses a method for determining water discharge at intake points under the conditions of lack of hydrological data. As an example is given the calculation of the river flow at intake points of the hydroelectric power chain cascade on the river Mtkvari (Chitakhevi HPP, ZAHPP, Ortachala HPP). The data taken from the hydrological stations of ,,Likani,, and „Tbilisi“ are multiplied by the adaptation coefficient, which is obtained by dividing catchment areas of Chitakhevi HPP ZAHPP and Ortachala HPP. The method allows to receive continuous average monthly and annual water discharge a
