By CS, a sparse signal can be perfectly recovered from a number of measurements, which is significantly lower than the number of periodic samples required by Sampling Theorem.
The THz radiation is nowadays of high interest due to its capability to emphasize the molecular structure of matter.
In imaging applications, one of the problems is the sensing device: the THz detectors are slow and bulky and cannot be integrated in large arrays like the CCD. The CS can provide an efficient solution for THz imaging. This solution is the single pixel camera with CS, a concept developed at Rice University that has materialized in several laboratory models and an IR camera released on the market in We reconsidered this concept in view of THz application and, at present, we have an experimental model for a THz camera.
The paper has an extended section dedicated to the CS theory and single pixel camera architecture.
In the end, we briefly presents the hardware and software solutions of our model, some characteristics and a first image obtained in visible domain. In this paper, we present three different, alternative applications of this numerical technique: resolution of the integral equation of convolution i.

In the transmission spectra of rare-earth doped glasses differs from that of the base glass. Author s : S. Bazgan ; I. Cojocaru; T. Rosca; G. Dorcioman; C. Ristoscu; G. Popescu-Pelin; N. Enaki ; I. Mihailescu Show Abstract Taking into consideration the granulate glass deposition of the TiO2 glass we propose a phenomenological model describing the nonlinear process of the growth of Ti Dating Agen? ie Lauren? ide. TiO2 films on Si or SiO2 substrates as function of temperature.
It is proposed that the phase transition can take place in earth granule so that the fixed Tg temperature is absent in comparison with traditional phase transition from thermodynamics. The continue temperature transition from crystalline to vitreous phase in the deposited films is analyzed based upon the nonlinear theory of phase transitions and the granulate aspect of deposited material.
Author s : Yu. Ushenko; V. Prysyazhnyuk; M. Gavrylyak; M. Gorsky ; V. Bachinskiy; O. Vanchuliak Show Abstract A new information optical technique of diagnostics of the structure of polycrystalline films of blood plasma is proposed.
The model of Mueller-matrix description of mechanisms of optical anisotropy of such objects as optical activity, birefringence, as well as linear and circular dichroism is suggested. The ensemble of informationally topical azimuthally stable Mueller-matrix invariants is determined. Within the statistical analysis of such parameters distributions the objective criteria of differentiation of films of blood plasma taken from healthy and patients with liver cirrhosis were determined.
From the point of view of probative medicine the operational characteristics sensitivity, specificity and accuracy of the information-optical method of Mueller-matrix mapping of polycrystalline films of blood plasma were found and its efficiency in diagnostics of liver cirrhosis was demonstrated.

Author s : George Stiubianu ; Adrian Bele; Codrin Tugui; Valentina Musteata Show Abstract New materials with large value for dielectric constant were obtained by using siloxane and chemically modified lignin.
The measured values for dielectric constant compare positively with the ones for previously tested dielectric elastomers based on siloxane rubber or acrylic rubber loaded with ceramic nanoparticles. The new materials use the well-known silicone chemistry and lignin which is available worldwide in large amounts as a by-product of pulp and paper industry, making its manufacturing affordable.
The prepared dielectric elastomers were tested for possible applications for wave, wind and kinetic body motion energy harvesting.

ide., chemical, microbiological and mechanical parameters. Reducing this cost would be a significant saving, and an effective treatment can reduce times related to ships repairing. Biofouling is a main cause of corrosion and for its reduction different methods could be applied, especially in the first part of its production.
The atmospheric pressure non-thermal plasmas have been gaining an ever increasing interest for different biodecontamination applications and present potential utilisation in the control of biofouling and biodeterioration.

They have a high efficiency of the antimicrobial treatment, including capacity to eradicate microbial biofilms. The adhesion microbial biofilm is mainly influenced by presence of bacteria from the liquid environment.
That is why this work concerns the study of annihilation of maximum amount of bacteria from sea water, by using GlidArc technology that produces non-thermal plasma.
Bacteria suspended in sea water are placed in contact with activated water. This water is activated by using GlidArc working in humid air. Experimental results refer to the number of different activated and inactivated marine organisms and their evolution, present in solution at certain time intervals after mixing different amounts of seawater with plasma activated water.

Biofouling is a main cause of corrosion and its formation contains four steps. To inhibit biofouling it is proposed a treatment based on non-thermal plasma produced by GlidArc, which can be applied before the immersion of small boats in the sea, as well as cleaning treatment of the hull after a period of time.
