In this paper, the influence of notch depth-to-width ratios on J-integral and critical load of Aluminium 8011 alloy specimens with U-notch under Mode I loading are studied. Using experiments, for a set of specimens having different notch depth–to–width ratios, J-integral was found and the same was verified using analytical methods. Further, using the results obtained from the experiments, failu...

Heart disease is one of the leading causes of death in human beings. A survey shows every year about 900,000 peoples die due to heart diseases worldwide. Carotid pulse is a pressure signal recorded over the carotid artery as it passes near the surface of the body at the neck. An abnormal carotid pulse called the dicrotic pulse occurs when patients suffer from sepsis, hypovolemic shock, cardiac ...

Fracture assessment of U- and V-notches is important in mechanical engineering. One can use the J-integral as fracture parameter in order to predict the critical fracture load in notches. The critical value of the J-integral in cracks is a function of the material properties. In notches, however, the material properties as well as the notch dimensions affect this critical value (named fracture ...

Objective(s): NOTCH signaling pathway is well known for its role in cell fate, cell survival, cell differentiation, and apoptosis. Some of the NOTCH signaling genes are critical for endometrial function and implantation in animals and appear to play a similar role in humans. The purpose of the current study was to investigate the potential roles of some main components of the NOTCH family in hu...

MIMO techniques promise a significant boost in the capacity of wireless systems. In this paper, MIMO system is designed using a compact double-sided printed antenna having ultra-wideband and band-notched characteristic. The UWB antennas are designed on CST Microwave studio simulation software with return loss less than -10dB, and further using the results from CST, performance analysis of diffe...

In this letter, a design of Compact Ultra-Wideband (UWB) bandpass filter with a switchable notch band for WLAN (5.3-5.9GHz) interference rejection is proposed. As 5.3-5.9GHz wireless local area network (WLAN) is existed in UWB spectrum range (3.1 -10.6GHz) and may interfere with UWB system operation. The UWB bandpass filter is implemented using a basic multiple mode resonator (MMR) structure fe...

During Drosophila oogenesis, follicle cells sequentially undergo three distinct cell-cycle programs: the mitotic cycle, endocycle, and gene amplification. Notch signaling plays a central role in regulating follicle-cell differentiation and cell-cycle switches; its activation is essential for the mitotic cycle/endocycle (M/E) switch. Cut, a linker between Notch signaling and cell-cycle regulator...

a critical protection requirement for grid connected distributed generators (dg) is anti-islanding protection. in this paper, a new islanding detection method for any possible network loading is proposed based on utilizing and combining various system parameter indices. in order to secure the detection of islanding, eight intentional disturbances are imposed to the system under study in which t...
