Optimal energy management of electric vehicles using slap swarm optimization and differential flatness control has been proposed. A battery-supercapacitor power system is adopted. Each source is connected in parallel to the DC-bus using DC-DC bidirectional converters and supplies a synchronous reluctance motor (SynRM) based drive.

This paper describes the detailed modeling and simulation of an aerogenerators system based on DFIG using RT-LAB simulator. A stator flux oriented vector is applied to decouple the control of active and reactive powers generated by the DFIG, and other controllers are needed to keep the DC-link voltage and grid currents at desired values. In order to adjust appropriately the pitch angle and keep the wind power at rated value, a pitch control and MPPT are involved.

Nivolumab, a completely human programmed death-1 inhibitor antibody, was first approved by the Food and Drug Administration for patients with advanced malignant melanoma resistant to other modalities of treatment. In 2015, it received approval as the first line of treatment for malignant melanoma. We aimed to synthesize evidence from published randomized-controlled trials on the safety and efficacy of nivolumab, either alone or in combination with ipilimumab, in the management of advanced unresectable melanoma.

This study focused on upgrading the antibacterial activity, UV-protection property, self-cleaning ability and durability to wash of linen and linen/cotton (50/50) blend fabrics to develop multifunctional textile materials without adversely affecting their hydrophilicity. Herein, linen-containing fabrics were first pre-carboxymethylated to create new active sites (-CHCOOH groups) to facilitate subsequent loading of selected active ingredients namely chitosan (Cs), organosilane quaternary ammonium compound (Si-QAC), silver-nanoparticles (Ag-NPs) and titanium oxide nanoparticles (TiO-NPs) individually and in admixtures. The developed products, especially in case of using mixed active ingredients, exhibit a noticeable improvement in the imparted functional properties regardless of the used substrate.

The color and odor of cosmetics have been shown to be crucial for affective states and able to influence autonomic responses. We report an original procedure to measure the effect on subjects of the color and odor of cosmetic products, and to quantify the correlation between objective (psychophysiological recording) and subjective (psychophysics) responses. Several cosmetic products (lipsticks and nail varnishes) of different colors (white, brown, red, orange, and pink) and odors (two per product) were presented.

In the present study, we familiarized menopausal women with a pleasant smell in the skin care products, they used for 1 week and assessed whether their mood and emotions improved using behavioural and physiological tools. Eventually, we studied the effects of inhaling the familiar fragrance on physiological response of the subjects. An anhedonia questionnaire was used to distinguish the effects of the test products according to low vs.

Whereas some aspects of olfactory hedonism in humans are present from birth, others form during development and throughout adulthood. Although it is generally agreed that such hedonic representations emerge by associative learning, it is not yet clear which learning parameters are prominent. The present study investigated the influence of number of trials on odor preference acquisition in human adults.

Recurrent varicose veins are due to unidentified connections between the deep and superficial venous systems. Conventional clinical and radiological methods of identification are inefficient. In a series of 662 operations the rate of recurrence was over 40%.
