Accelerating Perfect and Imperfect Loops Using Reconfigurable Architectures

, M.Sc. Thesis Sharif University of Technology Tanhaee, Effat (Author) ; Hesabi, Shahin (Supervisor)

Abstract

With the widespread use of mobile applications, multimedia and telecommunications, speed of execution has become important. The computation-intensive portions of applications, i.e., loops, devote a significant percentage of their implementation time. Thus, in this thesis, a new method is introduced which greatly increases the execution speed of the loops. Loops are often implemented on coarse-grained reconfiguration architecture (CGRAs) for acceleration, which is a promising architecture with high performance and high power efficiency in comparison to FPGA. In this regard, to reduce the execution time of two-level nested loops, if there are several innermost loops, first, we fuse them, then...

Characterization of Protein Content in Soluble Microbial Products Involved in Fouling of Membrane Bioreactor

, M.Sc. Thesis Sharif University of Technology Tanhaee, Zahra (Author) ; Torkian, Ayoub (Supervisor) ; Mousavi, Reza (Supervisor)

Abstract

Membrane bioreactors are increasingly being used for treatment of domestic and industrial effluents. A major operational drawback of this system is membrane fouling attributed to soluble microbial products (SMPs). In this study sampling were taken from microbial products on the surface and within the membrane pores and mixed liquir for mass characterization of protein content. Water-washing was used for surface and reversible portion of pore samples. Chemical wash with urea was used for further cleansing of SMPs within the pores. All samples were concentrate by precipitation with ammonium sulfate salt prior to analysis. Total protein content of samples was measured by lowry method. SDS-PAGE...

Modeling Cesium-137 Deposition and Absorption on Soil and Plants

, M.Sc. Thesis Sharif University of Technology Bagheri Farahbakhsh, Pouya (Author) ; Vosoughi, Naser (Supervisor) ; Movafeghi, Amir (Co-Advisor) ; Yahagi, Effat (Supervisor)

Abstract

Cesium-137 is one of the more important radionuclides in the environment because it is relatively abundant, it has a moderately long half-life (~30 y), its decay produces highly penetrating gamma radiation in addition to beta particles, and its biogeochemical properties allow it to move readily through food chains. It is a radioactive isotope of cesium which is formed as one of the more common fission product by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons.
In this reseach a model is introduced that could simulate a nuclear accident, its distribution into air, deposition into soil and absorption by plant. Nuclear accident and...
