Singhbhum Shear Zone (SSZ) is a geologically rich belt with structures like faults and folds being the distinctive features. Due to these characteristics this area has been an important centre of studies since past few decades. With the advent of Remote Sensing and GIS, it has been possible to study and interprete geological setting of any area in the laboratory itself without even visiting the...

Event datasets on political violence, which are comprised of coded collected news reports, have enjoyed a renaissance within the academic community. The inclusion of civilian fatalities within these datasets is a promising and welcomed advancement regarding the availability of data on one-sided violence. However, these datasets are often criticised due to their heavy reliance on media records, ...

در این پایان نامه چینه شناسی رسوبات سازند آسماری تاقدیس کوه سیاه در شمال شرق دهدشت، از نظر سنگ چینه نگاری، زیست چینه نگاری، رخساره ها و محیط رسوبی مورد مطالعه قرار گرفت. سازند آسماری در یال جنوبی تاقدیس کوه سیاه دارای ضخامتی حدود 267 متر بوده که متشکل از آهک های توده ای، ضخیم، متوسط تا نازک لایه با میان لایه های آهک مارنی به رنگ کرم تا خاکستری می باشد. در این برش سازند شیلی و مارنی پابده بصورت ...

A model for heat-recirculating micro combustor is developed. It investigates the structure of laminar, one-dimensional and steady state flame propagation in uniformly premixed wood particles with considering the effects of heat recirculation caused by configuration of micro combustor. The flame structure is divided into three regions: a preheat-devolatilization zone where the rate of the gas-ph...

This paper studies the credibility of a target zone considering the existence of heterogeneous expectations in the foreign exchange market. In general, we consider two types of agents: credible and non-credible agents (i.e. fundamentalists). One of the main results of the model is the possibility of collapse of a target zone as a function of expectations. This implies the existence of an endoge...

Panel zone is one of the most important elements for transferring the lateral load to other elements in Steel Moment Resistant Frames. To some extent, this element through its suitable ductile behavior with beams, that themselves have been known as ductile elements, can increase the overall ductility of SMRF. The suitable design procedure for this element and details, can highly affect the perf...

This paper presents a quantitative modeling for delineating alteration zones in the hypogene zone of the Miduk porphyry copper deposit (SE Iran) based on the core drilling data. The main goal of this work was to apply the Ordinary Kriging (OK), Artificial Neural Networks (ANNs), and Concentration-Volume (C-V) fractal modelings on Cu grades to separate different alteration zones. Anisotropy was ...

In this study, a simplified computational model of pile vertical vibration was developed. The model was based on the inhomogeneous radial disturbed zone of soil in the vicinity of a pile disturbed by pile driving. The model contained two regions: the disturbed zone, which was located in the immediate vicinity of the pile, and the undisturbed region, external to the disturbed zone. In the model,...
