Introduction: Tattooing has gain popularity since ancient time and become increasingly popular, particularly among young people. Advances in Laser Light based technology have revolutionized tattoo removal, using various wavelength to target color pigments lesser complications. The Q-switched Nd:YAG laser is considered the standard device of choice for removal. Aims: To evaluate efficacy safety ...

A new approach to nd optimal settings of model parameters as well as optimal models of dynamical systems is presented. The Adaptive Cross Validation (ACV) method is based on a number of well known ideas which are combined to a general optimization tool. It could be used for both design (oo-line) and control (on-line) of widespread applications, which can be both continuous and discrete. The met...

Two-photon excitation of a trifluorophore (6-carboxyfluorescein, N,N,N',N'-tetramethyl-6-carboxyrhodamine and cyanine-5 monofunctional dye) labeled DNA, which has a scaffold of 26 nucleotides, was achieved using focused laser light of a Q-switched Nd-YAG laser (1064 nm). The observed fluorescence signature (emission ratio from the three fluorophores) of the labeled DNA after two-photon excitati...

L inux PC Clusters are a cost effective platform for parallel computational uid dynamics (CFD) applications. In this paper we compare the performance of one CFD application on multiple clusters. Different networking architectures, like channel-bonding and Flat Neighborhood Networks (FNN), that use inexpensive switched Fast E thernet along with one high performance network (Myrinet) are consider...

We studied proton beam production from a laser ion source using hydrogen rich target materials. In general, gas based species are not suitable for laser ion sources since formation of a dense laser target is difficult. In order to achieve reliable operation, we tested hydride targets using a sub nanosecond Q-switched Nd-YAG laser, which may help suppress target material consumption. We detected...

Telephony is an Internet application that has the potential to radically alter the telecommunications environment. This application may a ect traditional regulatory structures, subsidy structures, business models, etc. Today, users can transmit telephone-like voice tra c over the Internet at zero incremental price, unlike circuit switched telephony, which has a per-minute incremental price. The...

in the present paper, we develop a modified pseudospectral scheme for solving an optimal control problem which is governed by a switched dynamical system. many real-world processes such as chemical processes, automotive systems and manufacturing processes can be modeled as such systems. for this purpose, we replace the problem with an alternative optimal control problem in which the switching t...
