Motivated by the simple models of molecular motor obeying a linear force-velocity relation, we have studied stochastic dynamics Brownian particle in presence velocity dependent force, $$f_s(1-\frac{v}{v_0})$$ where $$f_{s}$$ is constant. The position and auto correlation functions different situations are calculated exactly. We observed that function shows an exponentially decaying behaviour wi...

Cross-correlation interference introduced by stronger GPS signals constitutes a major problem in acquisition and tracking. For instance, the presence of a single strong GPS signal can mask other weak signals in indoor positioning. Furthermore, the use of GPS pseudolite can also cause near-far problem due to its proximity to the GPS receiver. The weak signal acquisition and tracking should also ...

variability in morphological traits, phenolic content, and antioxidant activity of 15 populations of iranian ferula species collected from natural habitats in different regions of iran were investigated. total phenolic content (tpc) of fruit extracts varied from 12.77 to 120.72 mg tannic acid per 1g dry weight. total flavonoid of fruits extract varied from 5.45 mg quercetin per 1 g dry weight i...

In this work, chaotic sequences with good auto-correlation properties are presented. The studied synthesized by means of the logistic map function and, been but fully deterministic, become a alternative for well-known sequences, example Zadoff-Chu especially small size commonly used frame synchronization purposes in digital communications systems. A new goodness metric is proposed, and it emplo...

In the vehicle communication system, transferred information is needed to be detected as possible as fast in order to avoid car accident and inform the road traffic fast. Fast communication defines that timing synchronization is detected fast. In this paper, we present combination method which can determine synchronization timing of frame is executed by auto-correlation and cross correlation si...

The acknowledgement of risks for traumatic brain injury in American football players has prompted studies for sideline concussion diagnosis and testing for neurological deficits. While concussions are recognized etiological factors for a spectrum of neurological sequelae, the consequences of sub-concussive events are unclear. We tested the hypothesis that blood-brain barrier disruption (BBBD) a...

the purpose of this article is to present the summary of all the research done on the weak form of efficient market hypothesis. these tests include normality test of return distribution, auto correlation test. run test and filter tests.

Reproducible definition and quantification of imaging biomarkers is essential. We evaluated a fully automatic MR-based segmentation method by comparing it to manually defined sub-volumes by experienced radiologists in the TCGA-GBM dataset, in terms of sub-volume prognosis and association with VASARI features. MRI sets of 109 GBM patients were downloaded from the Cancer Imaging archive. GBM sub-...

— This paper describes a search algorithm to find multiple sets of one dimensional unipolar (optical) orthogonal codes characterized by parameter ac nw. Here binary code sequence of length 'n' ('n' bits) and weight 'w' (number of bit '1's in the sequence) with w << n, as well as a  and c  are auto- from 1 to w-1, multiple sets can be searched out of the codes with auto-correlation constrai...
