background: muscle fatigue is an important issue in neuromuscular rehabilitation. better control of this phenomenon would result in better prevention of its consequent physiological damages. objective: to provide a mathematical representation of muscle fatigue as a function of time. methods: we conducted this study by combining the emg-based estimation methods of muscle activation with the avai...

introduction: purkinje cell (pc) output displays a complex firing pattern consisting of high frequency sodium spikes and low frequency calcium spikes, and disruption in this firing behavior may contribute to cerebellar ataxia. riluzole, neuroprotective agent, has been demonstrated to have neuroprotective effects in cerebellar ataxia. here, the spectral analysis of pcs firing in control, 3-acety...

Signal flow graphs with dataflow semantics have been used in signal processing system simulation, algorithm development, and real-time system design. Dataflow semantics implicitly expose function parallelism by imposing only a partial ordering constraint on the execution of functions. One particular form of dataflow, synchronous dataflow (SDF) has been quite popular in programming environments ...

Digital Image Processing is the use of computer algorithms to perform image processing on digital images. Digital image processing has many advantages over analog image processing. It allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and signal distortion during processing. Since images are defined over two dimensions, d...

introduction many features, emerging from mathematical techniques, have been used in the analysis of brain signals. in this study, the physical quantity of “moment of inertia” (moi) was introduced as a feature to enhance high-frequency waves (hfws) in electroencephalography (eeg). materials and methods in this research, the recorded eegs from f3, f4, and cz points in 20 males were used. a total...

Gabor lters have been applied sucessfully to a broad range of multidimensional signal processing and image processing tasks. The present paper considers the design of a single lter to segment a two-texture image. A new ef-cient algorithm for Gabor-lter design is presented. The algorithm draws upon previous results that showed that the output of a Gabor-ltered texture is well represented by a Ri...

Gabor filters have been applied sucessfully to a broad range of multidimensional signal processing and image processing tasks. The present paper considers the design of a single filter to segment a two-texture image. A new efficient algorithm for Gabor-filter design is presented. The algorithm draws upon previous results that showed that the output of a Gabor-filtered texture is well represente...
