The main novelties and capabilities of the second version Bare Electrodynamic Tether Mission Analysis Software (BETsMA v2.0) are presented. Recent advances on Orbital-Motion-Theory have been incorporated to electric model Low-Work-function Tethers (LWTs). An that considers a switch embed power supply or resistor between (BET) an electron emitter is also introduced. For both types tethers (LWT B...

Teleradiology plays a vital role in the medical field, which permits transmitting and imaging data over communication network. It ensures reliability provides convenient for clinical interpretation diagnostic purposes. The transmission of this network raises problems legal, ethical issues, privacy, copyright authenticity. protection images is significant issue field. Watermarking schemes are us...

The terrorism threat is multifaceted and ever-present; this as a result of terrorism taking on all forms including Islamic, non-Islamic, foreign and domestic. After 9/11, the federal government focused on jihadists and government resources were focused on engaging foreign jihadists allowing a resurgence of non-Islamic domestic terrorism including the lone wolf terrorist (LWT). The problem is th...

Underwater robots beneath ocean waves can benefit from feedforward control to reduce position error. This paper proposes a method using Model Predictive Control (MPC) to predict and counteract future disturbances from an ocean wave field. The MPC state estimator employs a Linear Wave Theory (LWT) solver to approximate the component fluid dynamics under a wave field. Wave data from deployed ocea...

Predictive control methods can substantially improve the performance of Unmanned Underwater Vehicles (UUVs), particularly in shallow water environments or near free surface where wave induced disturbance are magnitude comparable to vehicle characteristic inertia. To facilitate adoption these methods, a fast estimation time evolution hydrodynamic forces acting on is required. this end, we perfor...

In simple chemical oxidation such as the oxidation of pyrogallol or of a ferrous salt, the hydrogen ion concentration plays an important role. In general, as in the case of pyrogallol, a slight acidity depresses oxidation, and increasing alkalinity, even to a marked degree, greatly increases the rate of oxidation. It has been assumed that in general this applied also to biological oxidation, bu...

The main objective of the super resolution images is to enhance the quality of the multiple lower resolution images. Super Resolution image is constructed by using raw images. An Image with improved resolution is always desirable for various applications like satellite, medical etc. to enhance the qualitative features are the images. In this paper, Super Resolution Image Reconstruction (SRIR) i...

Compression is used to decrease the number of bits required to store and transmit images without any measurable loss of information. Lossless color image compression for an image in RGB color model is done by a Reversible Color Transformation. It converts RGB to YUV color model. Y component is encoded by method called Lifting Wavelet Transform (LWT) with Huffman coding. The lifting scheme is a ...
