Process networks are execution models expressing naturally the parallelism of a computation. This way, process networks are studied as models for parallel systems and allow to design theoretical studies, analysis, and measures for the various problematics related to parallelism. Process networks are a natural intermediate representation for parallelizing compilers, where the front-end extracts ...
Microwave heating is applied for processing different silicon raw materials, based on the size-, shapeand composition-dependent absorption of radiation of 2.45 and 916 MHz frequency by silicon. In model experiments directed towards the improvement of melting technology, Si-fines and chunks of bulk Silicon from Electronic Grade (EG)and Solar Grade (SG)-silicon production are used as raw material...
The dependence of the color of quartz and opal natural minerals, collected from different localities in the Republic of Macedonia (Alinci, Belutče, Budinarci, Mariovo, Sasa, Saždevo, Čanište, Češinovo, Zletovo) on their element composition is studied using Fourier transform infrared spectroscopy (FT IR), micro-Raman spectroscopy and atomic absorption spectrometry (AAS). In order to determine th...
PURPOSE To verify the accuracy of volumetric arc therapy (VMAT) using the RapidArc™ device when switching patients from one single linear accelerator (linac) to a paired energy and mechanics "twin" linac without reoptimization of the original treatment plan. PATIENTS AND METHODS Four centers using 8 linacs were involved in this study. Seventy-four patients previously treated with the 6MV phot...
We examine the internal structure of solar-like stars in detail between 0.8 and 1.4 M⊙ and during pre-main sequence phase. Recent opacity computations of OPAL along with a new hydrodynamical mixing process have been considered. We also introduce up-to-date nuclear reaction rates and explore the impact of accretion, mixing-length parameter, non-solar distributions among metals and realistic rota...
Optical sensors based on the interaction between molecular vibrations and mid infrared radiations attracted high attentions in the last decades. In this study, we present the development of a waveguide evanescent field sensor based on the absorption spectroscopy in liquid environments. The device consists of a single mode strip waveguide integrated with a microfluidic system. With a quantum cas...
Antihydrogen spectroscopy promises precise tests of the symmetry of matter and antimatter, and can possibly offer new insights into the baryon asymmetry of the universe. Antihydrogen is, however, difficult to synthesize and is produced only in small quantities. The ALPHA collaboration is therefore pursuing a path towards trapping cold antihydrogen to permit the use of precision atomic physics t...
Acknowledgements The completion of a doctoral thesis work is a long and complex task, and the author would like to thank all those who, over the years, have contributed to it. Special thanks go to Professor John Richard Thome for his support and encouragement. The discussion with him is always of interest and has yielded valuable progress continuously. I am also grateful for the lively discussi...
