the bound or gallop is used for high speed. A gallop occurs when only one paw is in the stance phase and no paws are in the stance phase or we called aerial phase \cite{mendes2015}. Step periodicity can be quantified by using Fast Fourier Transform (FFT) analysis applied to the horizontal component of the stepping trajectories \cite{fong2005}. The fundamental stepping frequency locates at the predominant peak. In the case of the poor stepping of the rat is shown‚ the fundamental peak is

modelling the evolution of some variable over time‚ so it is reasonable that the range of X t is the same across time. In that case we call the range of X t the state space. If the index set T is a countable set‚ we call the stochastic process a discrete-time process. If the index set is an interval of the real line‚ we call the process a continuous-time process. Although t is often used to indicate time‚ it can be used in other ways as well. For example‚ when modelling spatial phenomena (e.g

Considering digital image features with high volumes and video data‚ especially in real-time applications‚ the use of classic encryption methods like DES‚ AES‚ ...‚ is not efficient in terms of being time cosuming. In this article‚ a new method is proposed to encrypt digital images‚ using chos systems and utilizing DNA patterns. A central idea in the method suggested is to produce a pseudo-random DNA strand using chaos functions‚ which an encrypted strand is created‚ using the random strand and the

New forensic laser technique for hair analysis Using a new laser technique‚ Jim Moran and his colleagues at Pacific Northwest National Laboratory‚ have devised a method of separating out the parts of hair samples that can reveal details about the recent history of the person to whom it belongs. In their paper‚ published in Rapid Communications in Mass Spectrometry‚ they describe a process they’ve devised whereby hair samples are pulled apart‚ rather than burned as a whole before being measured

(amplitude and phase) of a system using ‘swept sine’ excitation. The resulting dynamic signal analyzer provides a convenient tool for obtaining empirical Bode plots of system and controller dynamics within the dSPACE environment. Both the derived (Fourier) and raw (time domain) data are displayed at each frequency tested. The bandwidth possible is linearly related to the sampling rate limits set by both the dSPACE board used and the complexity of the model. With the ds1102 and a simple model‚ at a

Compatibility studies of pure Zolmitriptan and excipients were performed via using fourier transformed infrared spectrophotometer (Shimadzu‚ Japan) in the range of 400-4000/cm-1 by using KBr disc method. A base line correction was made using dried potassium bromide KBr and

The natural plant exudate gum tragacanth is obtained from the stem of the bush like plant “goat’s-horn”‚ Astragalus species. Gum tragacanth has been used commercially for well over 2000 years and is currently widely used as a thickener and emulsifier in emulsion systems in different pharmaceutical‚ food‚ cosmetic and diverse industrial uses. In addition‚ it is on the list of stabilizers that are permitted by Food and Agriculture Organization/ World Health Organization that could be used during the
