The paper presents the results of implementation in the Matlab environment for watermarking embedder and extractor based on the Direct Sequence Spread Spectrum (DSSS). A block diagram of watermarking system, an analysis of watermarked signal reproduced as well as watermarking system robustness to degrading factors: lossy compression, signal-to-noise ratio (SNR) as well as a change in sampling f...

A static pressure-induced decomposition of indium hydroxide into metallic indium that takes place at ambient temperature is reported. The lattice parameter of c-In(OH)(3) decreased upon compression from 7.977(2) to approximately 7.45 A at 34 GPa, corresponding to a decrease in specific volume of approximately 18%. Fitting the second-order Birch-Murnaghan equation of state to the obtained compre...

In this chapter we describe methods how to compress spectral imaging data. Normally the spectral data is presented as spectral images which can be considered as generalizations of colour images. Rapid technological development in spectral imaging devices has initiated the need for the compression of raw data. Spectral imaging has been central to many remote sensing applications like geology and...

many studies have considered the effects of suspension properties on the dewatering process but fewhave focused on ore properties. thus, the present work studied the effects of ore properties (density,particle size, mineralogy) on the dewatering process based on lab and pilot experiments. a hydrocyclonewas used to prepare the required samples for the experiments. to study the effects of mineral...

spinal epidural haemorrhage may present as back pain associated with radicular symptoms and can be a catastrophic clinical scenario with progression to paraplegia or even sudden death. being a rare entity, it needs a high index ofclinical suspicion to diagnose it. fractures have been documented as a cause of hematorrachis but such hematomas only extend to one or two vertebral segments. large ep...

a 19-year-old man presented with a 5-year history of back pain radiating to the lower extremities and paresthesis of the toes during the last year. plain x-ray revealed a large cauliflower shaped exophytic mass at the level of t8, t9 and t10 vertebrae. computed tomography (ct) and magnetic resonance imaging (mri) showed an abnormal bony mass arising from the posterior arch of t9 with protrusion...

A program can be considered as a device that generates discrete time signals, where a signal is an execution. Shannon information rate, or bit rate, of the signals may not be uniformly distributed. When the program is specified by a finite state transition system, algorithms are provided in identifying information-rich components. For a black-box program that has a partial specification or does...

The Centre for Maritime Research and Experimentation conducted a geoacoustic inverse experiment in the Mediterranean Sea in the summer of 2012. Among the objectives was to employ an autonomous underwater vehicle to collect acoustic data to invert for properties of the seafloor. Inversion results for the compression wave speed in the bottom and the source spectrum of the R/V Alliance during a cl...

Professor Borivoje Nikolic Second Reader Date 2 ABSTRACT Future lithography systems must produce microchips with smaller feature sizes, while maintaining throughputs comparable to those of today's optical lithography systems. This places stringent constraints on the effective input data rate of any maskless lithography system. In recent years, my research group has developed a datapath architec...
