during recent years, examining the performance of contrarian strategies has been taken into consideration by scholars and stock market's activists, though several evidences are available based on profitability of this type of strategies, much of them have been referred to american and european's stock markets. in current study, the act of these strategies will be examined in tehran&ap...

INTRODUCTION Percutaneous access to kidney is a challenging technique that meets with the difficulty to reach rapidly and accurately an intra-renal target. Today, puncture guidance is performed under fluoroscopic or echographic imaging, each of which presents drawbacks: fluoroscopy provides limited 2D information on localization, whereas echography mostly gives fuzzy images of the target and th...

This paper presents an intelligent interpretation of ultrasonic C-scan results for carbon-fiber-reinforced plastic (CFRP) panels by using fuzzy logic approach. Ultrasonic C-scan results have relatively low resolution and poor imaging quality in anisotropic composites due to the speckle noise produced by the interference of backscattered signals. In this study, fuzzy logic was implemented to acc...

In this paper, we propose a scheme of autonomous guidance of spacecraft based on grayscale image. The autonomous guidance consists of 2 key technologies; topographic recognition and optical navigation. First, the pixel brightness in an image of the target surface is directly evaluated (without shape reconstruction) using a look-up table. A fuzzy-like logic determines an appropriate target site ...

This paper presents a new modeling of elevator group intelligent scheduling system with destination floor guidance. The traditional input mode of separate hall call registration and the destination selection is improved to a single-input mode. On this basis, dynamic partition method in up-peak traffic is studied. This method means dynamically adjust division of floor region based on flow rate a...

Industrial engineering is a field of profession that offers various work areas around the world. Since it has a wide variety of work areas, students encounter with the problem of taking a decision on which sector to work in the future. Therefore, a questionnaire has been conducted on 60 students who study at Industrial Engineering department at different universities in Turkey. Fuzzy AHP (Analy...

Many countries and scholars have used various strategies to improve and optimize the allocation ratios for carbon emission allowances. This issue is more urgent for China due to the uneven development across the country. This paper proposes a new method that divides low-carbon economy development processes into two separate periods: from 2020 to 2029 and from 2030 to 2050. These two periods hav...

introduction the iran has vast areas of karst landforms due to the relatively high carbonaceous rocks deposited during different geologic eras. karst landforms are noteworthy for investigation from many aspects. the primary importance of these regions is the considerable amount of underground water stored in karst formations. these reserves are favorable, both in quality and quantity, as natura...
