magnetite (fe 3 o 4  and nio) nanoparticles with a size range of 40–60 nm were prepared by sol-gel technique in nano and micro reverse micelles (water- in-oil). the surface properties, size, morphology and crystallographic structure of fe 3 o 4 and nio particles are characterized by means of x-ray diffraction, transmission electron microscope and scanning electron microscope which will give muc...

objective: common variable immunodeficiency (cvid) is one of the most frequent cases of primary immunodeficiency. it is likely that this heterogeneous disease is caused by several distinct genetic disorders. the activation-induced cytidine deaminase (aid) enzyme is involved in class switching, somatic hypermutation (shm) and processes associated with gene conversion in the germinal center. in o...

a new fault tolerant controller (ftc) has been presented in this research by integrating a fault detection and diagnosis (fdd) mechanism in a nonlinear model predictive controller framework. the proposed fdd utilizes a multi-sensor data fusion (msdf) methodology to enhance its reliability and estimation accuracy. an augmented state-vector model is developed to incorporate the occurred sensor fa...

Mashhad city, the second most populous metropolis of Iran, with a population of more than three million, lies between two seismically active regions of Binalood and Kopet-Dagh. In recent years, the city has grown around the South Mashhad (SM) fault zone in the south. Given the vital role of the SM fault in influencing the seismic risk of the city, this study is aimed at the evaluation of the fa...

Debugging is a time consuming task in hardware design. Thus effective debugging techniques are required when developing complex reliable systems. In this paper a new debugging approach based on the analysis of dynamic dependency graphs is presented. Our approach combines reverse debugging, dynamic forward/backward slicing, as well as spectrum-based fault localization and adapts them for the use...

The deformation pattern and strain partitioning in the Eastern Chinese Tian Shan are poorly known because of lack quantitative study kinematics rate major structure. Here we report a late Quaternary shortening for most active reverse fault-and-fold Shan. We quantified Huoyanshan structure based on detailed high-resolution remote sensing image interpretations, field investigations geological map...

This paper presents a novel approach for fault type estimation in power systems. The Fault type estimation is the first step to estimate instantaneous voltage, voltage sag magnitude and duration in a three-phase system at fault duration. The approach is based on time-domain state estimation where redundant measurements are available. The current based model allows a linear mapping between the m...

To realize the self-healing concept of smart grids, an accurate and reliable fault locator is a prerequisite. This paper presents a new fault location method for active power distribution networks which is based on measured voltage sag and use of whale optimization algorithm (WOA). The fault induced voltage sag depends on the fault location and resistance. Therefore, the fault location can be f...

Many researches have been currently conducted on the effects of fault distance on structures revealing that their seismic response can differ according to their distance from the fault. Suspension bridges due to their long period and high flexibility can be more sensitive to this phenomenon, especially in vertical vibration. Since the engineers tend to use longer spans, the length factor should...

Reverse faulting in Otago, southern New Zealand, accommodates distributed tectonic convergence on the eastern side of Australian-Pacific plate boundary. Paleoearthquake records from some faults region show highly variable earthquake recurrence times, with long periods quiescence separated by activity. Here we develop a longer-term context for these records, using cosmogenic radionuclide dating ...
