This paper investigates the reund-robin queueing system with two distinet inputsources. Two types of jobs arrive at the system in Poisson laws with parameters it and R2, respectively. Jobs' service times are subject to the exponential distributions with different means characterized th3 two types of jobs. With the round-robin discipline, the service facility pro:esses each type of job for a max...

In this paper, mesh-free element free Galerkin (EFG) method is extended to solve two-dimensional potential flow problems. Two ideal fluid flow problems (i.e. flow over a rigid cylinder and flow over a sphere) have been formulated using variational approach. Penalty and Lagrange multiplier techniques have been utilized for the enforcement of essential boundary conditions. Four point Gauss quadra...

this research is a cross-sectional study conducted to aim of comparison of self treatment between teacher and clinical nurse in tehran. in this study 100 teacher and 100 clinical nurses participate. for data gathering use of a questionnaire including tow part: one section about overall participants characteristics and another section including question about self treatment. the results show tha...

Flax (Linum usitatissimum) is widely used as a source of linen oil and fiber. As rule, the flax varieties are suitable for either seeds or stem fibers production. The “fiber” bring low seed, while “oil” ones have poor fibers. straw not textile industry has to be burned degraded naturally in field. However, it contains DP cellulose, which can at least varnish main challenge industrial applicatio...

In recent years, the demand for new applications using various Internet of Things (IoT) devices has led to an increase in number connected wireless networks. However, owing limitation available frequency resources IoT devices, degradation communication quality caused by channel congestion is a practical problem developing technology. Many have hardware and software limitations that prevent cent...

We propose an ILP system FOIL-I, which induces logic programs by a top-down method from incomplete samples. An incomplete sample is constituted by some of positive examples and negative examples on a nite domain. FOIL-I has an evaluation function to estimate candidate de nitions, the function which is composition of an information-based function and an encoding complexity measure. FOILI uses a ...
