اثر متقابل فاز پادفرومغناطیس (af) و ابررسانایی (sc) همواره مورد توجه فیزیکدانان تجربی و نظری بوده است. رقابت میان دو پارامتر نظم متفاوت در بسیاری از سیستم های گوناگون از جمله ابررساناهای دمای بالا دیده شده است. در برخی ترکیبات مثل اکسید مس فازهای پادفرومغناطیس و ابررسانایی بسیار نزدیک بهم ولی مجزا هستند؛ در حالی که در ترکیبات دیگری از قبیل ابررساناهای آلی، ترکیبات سه تایی و ترکیبات فرمیون های س...
In this paper, we present a new framework for simulating inter-vehicle communication. In this framework, we apply a commodity-based kinematic wave model for simulating traffic dynamics and network simulator 2 (NS-2) for the corresponding communication events. We demonstrate the feasibility of this framework with simulation results for inter-vehicle communication among individual vehicles and al...
introduction we aimed to introduce a 6-universal-prismatic-spherical (ups) parallel mechanism for the human jaw motion and theoretically evaluate its kinematic problem. we proposed a strategy to provide a fast and accurate solution to the kinematic problem. the proposed strategy could accelerate the process of solution-finding for the direct kinematic problem by reducing the number of required ...
This paper describes a numerical solution method for a dynamic network loading model that is consistent with the first order kinematic wave theory. The proposed procedure, called link transmission model (LTM), only requires calculations at network nodes. Compared to the cell transmission model (CTM), the computational complexity of the LTM is about n times smaller for the same level of accuracy...

The spatial representativeness of gauging stations was investigated in two low-mountainous river basins near the city of Trier, southwest Germany. Longitudinal profiles during low and high flow conditions were sampled in order to identify sources of solutes and to characterize the alteration of flood wave properties during its travel downstream. Numerous hydrographs and chemographs of natural f...
A mechanistic understanding of how fishes swim in unsteady flows is challenging despite its prevalence in nature. Previous kinematic studies of fish Kármán gaiting in a vortex street behind a cylinder only report time-averaged measurements, precluding our ability to formally describe motions on a cycle-by-cycle basis. Here we present the first analytical model that describes the swimming kinema...
