Abstract
Food choice is one of the most fundamental and most frequent value-based decisions for all animals including humans. However, the neural circuitry involved in food-based decisions is only recently being addressed. Given the relatively fast dynamics of decision formation, electroencephalography (EEG)-informed fMRI analysis is highly beneficial for localizing this circuitry in humans. Here, by using the EEG correlates of evidence accumulation in a simultaneously recorded EEG-fMRI dataset, we found a significant role for the right temporal-parietal operculum (PO) and medial insula including gustatory cortex (GC) in binary choice between food items. These activations were uncovered by using the...
Value-based Optimal Design of FPB and LRB Isolators for Short to Medium Rise Buildings
, Ph.D. Dissertation Sharif University of Technology ; Esmail Pourestekanchi, Homayoon (Supervisor)
Abstract
Seismic base isolation is the most effective method of protecting and strengthening structures against seismic damage caused by large to small earthquakes and aftershocks. Providing damping and energy absorption of the seismic isolation at the structure's base level can significantly reduce the cost of repairing and strengthening the structure in addition to reducing seismic damage. However, besides these advantages, due to their high cost, seismic isolations in major infrastructure projects, hospitals, and crisis management centers should have economic and social justification. In this regard, a value-based seismic design approach can justify this important issue. In recent years of...
Value-Based Design of Actual Structure Designed by the Common Codes in Tehran, using Endurance Time Method
, M.Sc. Thesis Sharif University of Technology ; Esmaeil Pourestekanchi, Homayoon (Supervisor)
Abstract
The objective of this study is to design a real structure based on value using the endurance time method, which is designed according to common design codes. In the value-based design of this structure, a variation of the lateral load coefficient has been used for the design of the investigated structural specimens. The term "value" in this research refers to the total costs incurred over the lifespan of the structure. The initial construction costs of the structure and the life cycle costs are optimized in the value-based design process. The initial construction cost in this research consists of two parts: the first part is variable costs that arise from the consumed materials in the...
Adaptive neuro-fuzzy inference system in fuzzy measurement to track association

Abstract
The main issue in a surveillance environment is the target tracking. The most important concern in this problem is the association of the various measurements with the existing target tracks. The fuzzy c-means data association (FCMDA) algorithm, based on the fuzzy c-means (FCM) algorithm, is an efficient solution for the problem of measurement to track association in a multisensor multitarget environment. It has a high accuracy in measurement to track association when targets are far from each other. However, its accuracy remains low when targets are close to one another. The FCMDA algorithm performance is usually lost in this environment, especially when measurement noise is high. In the...
