the main purpose of this paper is theoretically to design the optimal intervention in the foreign exchange market in iran, which has not been investigated by previous studies. the economic fundamentals are strongly affected by the optimal foreign exchange intervention, the consistency of foreign exchange intervention with other policies and political authorities' beliefs about the interven...

The bandwidth demands of the World Wide Web continue to grow at a hyper-exponential rate. Given this rocketing growth, caching of web objects as a means to reduce network bandwidth consumption is likely to be a necessity in the very near future. Unfortunately, many Web caches do not satisfactorily maintain cache consistency. This paper presents a survey of contemporary cache consistency mechani...

Display-camera communication has become a promising direction in both computer vision and wireless communication communities. However, the consistency of the channel measurement is an open issue since precise calibration of the experimental setting has not been fully studied in the literatures. This paper focuses on establishing a scheme for precise calibration of the display-camera channel per...

Given a distributed system with several shared objects and many processes concurrently updating and reading them, it is convenient that the system achieves convergence on the value of these objects. Such property can be guaranteed depending on the consistency model being employed. Causal Consistency is a weak consistency model that is easy and cheap to implement. However, due to the lack of rea...

This report analyzes the performance of two methods for maintaining object consistency in World Wide Web proxy cache servers: the widely used Alex adaptive TTL protocol and a proposed Distributed Object Consistency Protocol (DOCP). The goal of this report is to evaluate these approaches to web cache consistency using a realistic workload and trace-driven simulation. We examine the effect of cac...

cryptosporidium is an important cause of illness in farm animals. the present study conducted in kerman, iran between 2003-2004 to elucidate the epidemiology of cryptosporidium infection in sheep and goats. fecal samples were collected fresh and transferred to the research lab. cryptosporidium oocysts were concentrated using formalin-ether sedimentation method followed by the modified ziehl-nee...

Analytic hierarchy process (AHP) is a well-known attribute weighting method in multiattribute decision-making. Its major requirement to satisfy the consistency of pairwise matrix (PM). To solve this problem, we first propose new improvement PM based on ratio (CR) decreasing rate. In method, calculate CR rates all PMs reconstituted by replacing elements with lower and upper neighbouring 9-point ...

We present a new mimetic finite difference method for diffusion problems that converges on grids with curved faces. Crucially, it gives symmetric discrete problem uses only one unknown per face. The principle at the core of our construction is to abandon standard definition local consistency methods. Instead, we exploit novel and global concept P0-consistency. Numerical examples confirm optimal...
