in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
the present work is focused on the degradation of 4-chloro-2-nitrophenol in aqueous solution containing nano titanium dioxide, hydrogen peroxide and the combination of nano-tio2/h2o2. the effect of experimental parameters, such as the amount of nano- tio2 concentration of h2o2, initial concentration of 4-chloro-2-nitrophenol and ph on the reaction was investigated. experimental data obtained un...
We have successfully built and operated a source deployment system for the KamLAND detector. This system was used to position radioactive sources throughout the delicate 1-kton liquid scintillator volume, while meeting stringent material cleanliness, material compatibility, and safety requirements. The calibration data obtained with this device were used to fully characterize detector position ...
we aimed to study the mntnhex-2-pyp effect on some markers of lung antioxidant defence system in mice asthma model.the study was carried out on 28 c57b1/6 mice divided into four treatment groups: group 1 - controls; group 2 - injected and inhaled with ovalbumin; group 3 - treated with mntnhex-2-pyp and inhaled with phosphate buffered saline; group 4 - injected with ovalbumin and mntnhex-2-pyp b...
Sat4j is a mature, open source library of SAT-based solvers in Java. It provides a modular SAT solver architecture designed to work with generic constraints. Such architecture is used to provide SAT, MaxSat and pseudo-boolean and solvers for lightweight constraint programming. Those solvers have been evaluated regularly in the corresponding international competitive events. The library has been...
در یک تقسیم¬بندی کلّی، اقتصاد یک کشور را می¬توان به دو بخش رسمی و غیر قابل مشاهده تقسیم¬بندی کرد. ملاک این تقسیم¬بندی، قابلیت ثبت و گزارش فعالیت¬های اقتصادی مورد نظر به¬طور رسمی است. در واقع، به¬دلایل متعددی، ابعادی از فعالیت¬های اقتصادی چه در بخش تولید و چه در بخش مبادله از دید منابعِ ثبت و گزارش¬دهی پنهان می¬مانند. این فعالیت¬ها تحت عناوین مختلفی از جمله اقتصاد غیر رسمی، اقتصاد پنهان و اقتصاد...
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
