The Byzantine agreement problem requires a set of n processes to agree on a value sent by a transmitter, despite a subset of b processes behaving in an arbitrary, i.e. Byzantine, manner and sending corrupted messages to all processes in the system. It is well known that the problem has a solution in a (an eventually) synchronous message passing distributed system iff the number of processes in ...
فرض کنید a یک جبر باناخ باشد. ما در این پایان نامه ایده آل های بسته i از a که اولین گروه کوهمولوژی از a با ضرایبی در i^* است را مطالعه می کنیم یعنی 0=( a,i^*) h^1 . همچین ایده آل های بسته را وقتی a میانگین پذیر ضعیف یا دوهمواری است و نیز بعضی خواص ارثی ایده آل های میانگین پذیر را بررسی می کنیم.
فرض کنید r یک حلقه ی نوتری جابجایی و m یک r-مدول متناهی مولد باشد. در این پایان نامه نشان خواهیم داد که اگر برای یک عدد صحیح t ، به ازای هر i<t، h_a^i (m)، -مین مدول کوهمولوژی موضعی نسبت به ایده آل a متناهی مولد باشد آنگاه به ازای هر عضو a-فیلتر رشته ی منظم مانند که در توانهای به اندازهی کافی بزرگ a قرار دارد و هر i<t-1، داریم: h_a^i (m/xm)?h_a^i (m)? h_a^(i+1) (m).
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...

arsenic trioxide (ato) has been reported to induce apoptosis in leukemic cells of acute promyelo-cytic leukemia (apl) patients through different pathways. however, the exact mechanism of ato-induced apoptosis is not yet clear. co stimulation of death receptors cd30 and tumor necrosis factor receptor type one (tnfr-i) is one of the postulated mechanisms.in the present study we aimed to evaluate ...
the purpose of the present study was to see which one of the two instruction-processing instruction (pi) and meaningful output based instruction (mobi) accompanied with prompt and recast- is more effective on efl learners’ writing accuracy. in order to homogenize the participants in term of language proficiency a preliminary english test (pet) was administrated between 74 intermediate students ...
introduction: micap is a new notation in which the teeth are indicated by letters (i-incisor, c-canine, p-premolar, m-molar) and numbers [1,2,3] which are written superscript and subscript on the relevant letters. fdi tooth notation is a two digit system where one digit shows quadrant and the second one shows the tooth of the quadrant. this study aimed to compare the short term retention of kno...
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
