Abstract Near Eastern monumental buildings once hosted institutions with a variety of economic and environmental footprints. In this article examining Middle Bronze Age II (seventeenth century BC) building complex at Zincirli, Turkey, we integrate bioarchaeological remains ceramic artifactual evidence to evaluate whether was specialized node in broader network centralized economy. Combining see...
Cattle traction was a technological innovation that made significant impact on production, individual and household wealth, social organisation. Despite ongoing debates regarding the origins extent of harnessing cattle power among early agropastoral societies, only few studies have attempted at addressing this matter systematically. In Neolithic Çatalhöyük, several explored symbolism domesticat...
today air conditioning systems have been considered by all people as one of welfarerequirements in buildings and closed environments. since a considerable part of energy lossoccurs in ordinary modern systems, new strategies and solutions are developed in the field inorder to save amount of energy consumption and observe environmental considerations. fuzzycontrol is one of these methods which pr...
This study spatially assesses, quantifies, and visualizes the agricultural expansion and land use intensification in the northwestern foothills of Mount Kenya over the last 30 years: processes triggered by population growth, and, more recently, by large-scale commercial investments. We made use of Google Earth Engine to access the USGS Landsat data archive and to generate cloud-free seasonal co...
Understanding the relationships between ecosystem services is important for promoting ecosystem service management and sustainable development. The relationships between ecosystem services have commonly been characterized as tradeoffs and synergies. Here, we report that a third type of relationship also exists, in which one ecosystem service constrains the other. Selecting the grassland and agr...
ازآنجایی که اغلب سیستم های فیزیکی غیرخطی اندبنابراین شناسایی وآنالیزسیستم های غیرخطی ضرورت پیدامی کند. دربحث آنالیز سیستم های غیرخطی که سیستم براساس ورودی-خروجی باشدورودی سیستم مشخص است و خروجی در یک بازه زمانی با استفاده از توابع متعامد باید تقریب زده شودکه آنالیزاین نوع خاص ازسیستم های غیرخطی تاکنون انجام نشده بودکه مابااستفاده ازماتریس حاصلضرب موجک، آنالیزاین نوع ازسیستم های غیرخطی رابادقت ب...
the study of the dynamic behavior of a rigid body with one fixed point (gyroscope) has a long history. a number of famous mathematicians and mechanical engineers have devoted enormous time and effort to clarify the role of dynamic effects on its movement (behavior) – stable, periodic, quasi-periodic or chaotic. the main objectives of this review are: 1) to outline the characteristic features of...
aim and background: the behavioral inhibition system (bis) and the behavioral activation system (bas) are considered as factors to verify the effects of personality significance on cortical activity. the present study explored the effects of the bis and bas on frontal asymmetry in response to affect stimuli. methods and materials: this study included 36 individuals (18 with high bas sensitivity...
