BACKGROUND In recent years, there is an increasing tendency to use diced cartilage grafts in rhinoplasty surgery for improving dorsum contour irregularities. This study was designed to compare graft resorption between three techniques of diced cartilage using surgical blade, electrical grinder and grater in rabbit model. METHODS Thirteen New Zealand rabbits were divided into three groups. Th...

In this paper, proposed an advance approach for dynamic data protection using LSB and hybrid approach. Steganography is the art of communicating a message by embedding it into multimedia data. The proposed method for replacing one or two or three LSB of each pixel in video frame and apply Advance encryption standard (AES). It becomes very difficult for intruder to guess that an image is hidden ...

The piece in hand (PH) is a general scheme which is applicable to any reasonable type of multivariate public key cryptosystems for the purpose of enhancing their security. In this paper, we propose a new class PH method called NLPHPV (NonLinear Piece in Hand Perturbation Vector) method. Although our NLPHPV uses similar perturbation vectors as is used for the previously known internal perturbati...

High dynamic range (HDR) imaging from a set of sequential exposures is not an easy way to capture high quality images of static scenes due either observational constraints or design constraints. It also suffers from artifacts for scenes with significant motion. In this paper, we proposed a new approach to HDR reconstruction that not only draws information but also it is more robust to camera sc...

Over the past 50 years, countries of the Caribbean Region have experienced an Epidemiological Transition [1-4]. In fact, data from the Pan American Health Organization (PAHO) suggests that the Caribbean epidemic of chronic non-communicable diseases (CNCDs) is the worst in the region of the Americas [5,6]. The overall epidemiology of Diabetes and cardiovascular disease in the Caribbean has revie...

In this paper are presented a CMOS Gm-C state-space active filter for high frequencies, in the 1μm CMOS process, synthesised using the intermediate transfer function method. The Gm transconductor has a good linearity (1% relative error for 2Vp-p input signals with a 5V power supply) and high DC gain (≥40dB), combined with a large band to avoid errors in the filter characteristic. By using the i...

Thalidomide is a sedative drug introduced to European markets on 1 October 1957 after extensive testing on rodent embryos to ensure its safety. Early laboratory tests in rodent populations showed that pregnant rodents could safely use it, so doctors prescribed Thalidomide to treat morning sickness in pregnant women. However, in humans [3] Thalidomide interfered with embryonic and fetal developm...

Image segmentation is a classical problem in computer vision and is of paramount importance to medical imaging. The segmentation is complicated by lack of clarity, the overlap of intensities and many other factors. We present a hybrid algorithm for obtaining segmentation of images that are subject to noise and multiplicative intensity nonuniformity. The algorithm is formulated by the combinatio...

We study a queueing system with a Poisson arrival process and Markov modulated, exponential service requirements. For a modulating Markov Chain with two states, we show that the distribution of the number-in-system is a superposition of two matrix-geometric series and provide a simple algorithm for computing the rate and coefficient matrices. These results hold for both finite and infinite wait...

In this study the optimum conditions for preparing the iron-doped TiO2 nanoparticles were investigated. Samples were synthesized by sol-gel impregnation method. Three effective parameters were optimized using Taguchi method, consisted of: (i) atomic ratios of Fe to Ti; (ii) sintering temperature; (iii) sintering time. The characterization of samples was determined using X-ray diffraction, BET- ...
