UOVR and UOFR as passive anti-islanding methods lack of sensitivity to detect islanding. The performance gets worse when the frequency threshold is increased from 50.2 Hz to 50.6 Hz. For instance, dedicated passive methods such as ROCOF help the inverter to detect islanding. When active methods such as SFS and SVS are activated, the number of detected islandings is increased to 87.5%. To improv...

Correspondence to: Mohammad Amani Tehran email: [email protected] ABSTRACT In this study, color coordinates variation of spundyed polyester filament yarns subjected to the false twist texturing process was investigated. Furthermore, the effect of different processing parameters including D/Y ratio, twist, heater temperature, texturing speed, overfeed, the draw ratio and intermingling process on t...

Insect wings are deformable structures that change shape passively and dynamically owing to inertial and aerodynamic forces during flight. It is still unclear how the three-dimensional and passive change of wing kinematics owing to inherent wing flexibility contributes to unsteady aerodynamics and energetics in insect flapping flight. Here, we perform a systematic fluid-structure interaction ba...

Hemagglutination inhibition, enzyme-linked immunosorbent assay (ELISA), and passive latex agglutination were used to test 495 human serum samples for determination of rubella immunity. Overall agreements for immune status were as follows: hemagglutination inhibition versus ELISA, 94.7% (469 of 495); hemagglutination inhibition versus passive latex agglutination (1:10 dilution), 99.2% (491 of 49...

background: left ventricular (lv) twist is due to oppositely directed apical and basal rotation and has been proposed as a sensitive marker of lv function. we sought to assess the impact of chronic pure mitral regurgitation (mr) on the torsional mechanics of the left human ventricle using tissue doppler imaging. methods: nineteen severe mr patients with a normal lv ejection fraction and 16 non-...

ab initio calculation at hf/6-31g* level of theory for geometry optimization and mp2/6-31g*//hf/6-31g* for a single point total energy calculation are reported for the important energyminimumconformations and transition-state geometries of of cyclodeca-1,2,3-triene (1). the mostfavorable conformation of 1 is a unsymmetrical twist-chair (1-tc) structure. degenerateinterconversion of 1-tc with it...

– The mean time between submission and acceptance was 1.4 months. Also, since January 2007, the journal has been published in its entirety in English, in digital format, and freely accessible without subscription through MEDLINE. This online access has been a complete success. For the immediate future we have proposed the fulfillment of the dream of many members: to finally have an impact facto...

Interacting with a smart watch requires a fair amount of attention, which can disrupt a user’s primary activity. While single-handed gestures have been developed for other platforms, they are cumbersome to perform with a watch. A simple interaction is needed that can be used to quickly and subtly access the watch at the user’s convenience. In this paper, we developed Twist 'n' Knock—a one-hande...
