This work is aimed at optimizing the wind turbine rotor speed setpoint algorithm. Several intelligent adjustment strategies have been investigated in order to improve a reward function that takes into account the power captured from the wind and the turbine speed error. After different approaches including Reinforcement Learning, the best results were obtained using a Particle Swarm Optimizatio...

Carbon nanotubes (CNTs) are generally considered as a promising particle reinforcement of incorporating advanced properties and characteristics into epoxy nanocomposites. This paper investigated the bonding performances CNT-reinforced adhesively bonded joints on steel substrates using single lap shear (SLS) tests. The (including strength, fracture strain, toughness, failure mode) were studied w...

during the past two decades, the use of bioplastics as an alternative to regular plastics has received much attention in many different industries. the mechanical and degradable properties of bioplastic are important for their utilization. in this research cellulose of wheat straw and glycerol were mixed by different weight ratios and then reinforced by using date palm fibers. to prepare the bi...

in this work, a new aluminum matrix nanocomposite reinforced with beta-magnesium aluminide nanoparticles was produced by powder metallurgy technique. the prealloyed al-40 wt.% mg intermetallic ingot was milled for 100 hours to synthesize β-al3mg2 nanoparticles with the average size of 25 nm. different amounts of nanoparticles were added to al matrix powder and the mixture was then milled for 10...

Resin transfer moulding (RTM) is commonly used for the production of high-performance fibre-reinforced polymer composites. In numerous application areas, the addition of fillers is necessary to enhance some properties of the polymer matrix or provide it with additional properties, such as flame retardancy. As many of the applied additives are solid phase, the reinforcement layers may filter the...

o bjectives: heat-polymerized acrylic resin has been the most commonly used denture base material for over 60 years. however, the mechanical strength of acrylic resin is not adequate for long-term clinical performance of dentures. consequently, fracture is a com- mon clinical occurrence, which often occurs in the midline of denture base.this study aimed to evaluate the efficacy of cold cure and...

the main challenge of a search engine is ranking web documents to provide the best response to a user`s query. despite the huge number of the extracted results for user`s query, only a small number of the first results are examined by users; therefore, the insertion of the related results in the first ranks is of great importance. in this paper, a ranking algorithm based on the reinforcement le...

BACKGROUND Food reinforcement and dopaminergic activity may influence food consumption, but research on whether they interact has not been performed. OBJECTIVE We assessed the effects of food reinforcement and the interaction of food reinforcement with the dopamine transporter (SLC6A3) genotype and the dopamine D(2) receptor (DRD(2)) genotype on energy consumption. DESIGN We studied food-co...

In this article, the thermo-elastic behavior of a functionally graded simple blade subjected to the mechanical and thermal loadings is presented, applying a semi-analytical method and a variable thickness cantilever beam model. A specific temperature gradient is employed between the root and the edges of the beam. It is assumed that the mechanical and thermal properties are longitudinal directi...
