in this paper, the definition of meet-continuity on $l$-directedcomplete posets (for short, $l$-dcpos) is introduced. as ageneralization of meet-continuity on crisp dcpos, meet-continuity on$l$-dcpos, based on the generalized scott topology, ischaracterized. in particular, it is shown that every continuous$l$-dcpo is meet-continuous and $l$-continuous retracts ofmeet-continuous $l$-dcpos are al...

network sensors consist of sensor nodes in which every node covers a limited area. the most common use ofthese networks is in unreachable fields.sink is a node that collects data from other nodes.one of the main challenges in these networks is the limitation of nodes battery (power supply). therefore, the use oftopology control is required to decrease power consumption and increase network acce...

در این پایان نامه، ابتدا تعریفی از توپولوژی روی اشیاء و پیوستگی روی ریخت های یک رسته ی دلخواه بیان کرده ایم. همچنین نشان داده ایم این تعاریف شامل تعاریف توپولوژی و پیوستگی استاندارد می باشند. سپس مثال های متعددی از جمله مثال هایی از توپولوژی فازی را بیان کرده ایم و ثابت می کنیم که این توپولوژی های فازی همگی حالت خاصی از توپولوژی در رسته می باشند. در انتهاء توپولوژی القائی در رسته را تعریف کرده ...

A number of algorithms based on the evolutionary processing have been proposed forcommunication networks backbone such as Genetic Algorithm (GA). However, there has beenlittle work on the SWARM optimization algorithms such as Particle Swarm Optimization(PSO) for backbone topology design. In this paper, the performance of PSO on GA isdiscussed and a new algorithm as PSOGA is proposed for the net...

performance of the fiber optic networks with different physical topologies such as point-to-point, bus, ring and star, with respect to requirements as bit rates, topology structure, bit. error rate (ber) and optical component characteristics including optical amplifiers, filters, sources and detectors, are analyzed and simulated. for this purpose, maximum number of supportable nodes and throug...

Multilevel inverters have been developed due to limitations of the conventional two-level voltage source inverters (VSIs). Most of the topologies of multilevel inverters that have been presented in the literature are based on the sharing of the rated voltage between the switches so that the switches with lower voltage ratings can be used. In these topologies, the current rating of all of the sw...

Consider the restriction of directed landscape $${\mathcal {L}}(x, s; y, t)$$ to a set form $$\{x_1, \dots , x_k\} \times \{s_0\} {\mathbb {R}}\times \{t_0\}$$ . We show that on any such set, is given by last passage problem across k locally Brownian functions. The functions in this isometry are built from certain marginals extended landscape. As applications construction, we Airy difference pr...
