Monoclonal antibodies (mAbs) are highly complex proteins that display a wide range of microheterogeneity that requires multiple analytical methods for full structure assessment and quality control. As a consequence, the characterization of mAbs on different levels is particularly product - and time - consuming. This work presents the characterization of trastuzumab sequence using sheathless cap...
Hot ring rolling is a highly nonlinear, unsteady-state and asymmetry process which is affected by many parameters. The friction coefficient between the ring ,the driver roll and the idle roll is one of the problems, which has significant effect on the quality of final product. In this study, the effect of these two parameters on hot ring rolling was investigated based on a 3D coupled-thermo mec...
The coalition formation problem in an economy with externalities can be adequately modeled by using games in partition function form (PFF games), proposed by Thrall and Lucas. If we suppose that forming the grand coalition generates the largest total surplus, a central question is how to allocate the worth of the grand coalition to each player, i.e., how to find an adequate solution concept, ta...
We extend RBPP, the state-of-the-art, translation-based planner for conformant probabilistic planning (CPP) with deterministic actions, to handle a wide set of CPPs with stochastic actions. Our planner uses relevance analysis to divide a probabilistic ”failure-allowance” between the initial state and the stochastic actions. Using its ”initial-state allowance,” it uses relevance analysis to sele...
نوسان ساز ها جزء لا ینفک بسیاری از سیستم های الکترونیکی هستند. کاربرد های آنها تولید ساعت در ریزپردازنده ها تا سنتز فرکانس حامل در تلفن های سلولی را در بر می گیرد که نیاز به توپولوژیهای متفاوتی از نوسان ساز ها با درجات متفاوتی از کارایی دارند.طراحی نوسان ساز مقاوم و کارا در فناوری cmos جزء مسائل جالب است.معمولا نوسان ساز ها را در یک حلقه ی قفل فاز(pll) بکار می برند با توجه به کاربرد pll ، بحث م...
Bresar in 1993 proved that each biderivation on a noncommutative prime ring is a multiple of a commutatot. A result of it is a characterization of commuting additive mappings, because each commuting additive map give rise to a biderivation. Then in 1995, he investigated biderivations, generalized biderivations and sigma-biderivations on a prime ring and generalized the results of derivations fo...
این پایان نامه بر اساس مراجع [4] و [5] تنظیم شده است. در این پایان نامه پس از معرفی مقدماتی مشبکه های برداری و ایده آل ها، که مباحث آنها در [11] و [14] آغاز شده است، به اثبات قضیه ای می پردازیم که بر اساس آن قضیه، یک طبقه بندی از یک ایده آل ترتیبی در فضاهای ریس ارائه می شود. در ادامه با استفاده از مرجع [1] به گسترش و توسعه اطلاعات خود در رابطه با ایده آل ها و باند ...
field saturated hydraulic conductivity (kfs) is one of the most important soil properties that considerably contribute to soil quality. however, specifically in the structured soils, the measurement of kfs is difficult and time-consuming. therefore, verifying the simple and fast methods for kfs measurement is needed for effective soil monitoring. this study was conducted to investigate the effe...
In this paper we give conditions under which a ring is isomorphic to a structural matrix ring over a division ring.
The effect of alkyl substituents on the C-phenyl and/or the N-Phenyl ring of benzophenylhydroxamic acid on their molecular structure and hydrogen bonding has been investigated. The predominant configuration in CHCl3 is determined by steric and electronic effects. Substituents on the C-phenyl ring favor the cis configuration, while substituents in the N-phenyl ring favor a trans c...
