saluk mount is selected for devonian biostratigraphy. this area located at southwest of bojnurd. in this study three sections are selected and two sections, chahar-borj and tabar sections with a thickness of 650 m, which consist mainly of calcareous sediments was studied in detailed but third section, qelli section, with a thickness of about 450m which consist mainly of sandstone and evaporates...
The bearings are the most important mechanical elements of rotating machinery. They are employed to support and rotate the shafts in rotating machinery. On the other hand, any fault in bearing can lead to losses on the level of production and equipments as well as creation an unsafe working environment for human. For these reasons, Condition monitoring and fault diagnosis of these bearings has ...
Energy saving in networks has traditionally focussed on reducing battery consumption through smart wireless network design. Recently, researchers have turned their attention to the energy cost and carbon emissions of the backbone network that both fixed and mobile communications depend on, proposing primarily mechanisms that turn equipments OFF or put them into deep sleep. This is an effective ...
In [RS07, RS08], Reimann and Slaman raise the question “For which infinite binary sequences X do there exist continuous probability measures μ such that X is effectively random relative to μ?”. They defined the collection NCR1 of binary sequences for which such measures do not exist (we give formal definitions below), and showed, for example, that NCR1 is countable, indeed that every sequence i...
Security is the primitive issue for humanity. From Paleolithic age, people are trying to secure themselves from natural calamity, furious animals and other adversities. With the advancement of technology, we get Machine gun, Nuclear Bomb, and many such powerful types of equipment for security. All these powerful equipments are used for protecting the border of a country, or in war against the e...
statement of problem: microorganisms are essential for the development of periradicular diseases and are one of the major causative factors associated with endodontic treatment failures. different instruments and preparation techniques have been developed in endodontics to eliminate or reduce intracanal bacteria. purpose: the aim of this study was to compare the amount of remaining e. faecalis ...
in chapter 1, charactrizations of fragmentability, which are obtained by namioka (37), ribarska (45) and kenderov-moors (32), are given. also the connection between fragmentability and its variants and other topics in banach spaces such as analytic space, the radone-nikodym property, differentiability of convex functions, kadec renorming are discussed. in chapter 2, we use game characterization...
In this work we consider an industrial maintenance process control problem using cellular automata approach. The problem consists on finding an optimal control for the assignment and the displacement of agents in a spatial area to maintain the equipments in good working state. The approach by cellular automata is based on: an operating statistics for determining the attributes of equipments and...
Coumaphos is a common organophosphorus pesticide used in agricultural products. It is harmful to human health and has a strictly stipulated maximum residue limit (MRL) on fruits and vegetables. Currently existing methods for detection are complex in execution, require expensive tools and are time consuming and labor intensive. The surface plasmon resonance method has been widely used in biomedi...
oil is a strategic product in our country, iran. the amount of importing this product is considerable, and therefore, any attempt to produce crude oil in our country in a way that competes with the foreign counterparts, with regard to both quality and production cost is considered important. this study addresses the effect of oil seeds preparation step on quality of crude oil, which is extracte...
