A Primer to Bayesian Methods in Cryptanalysis
, M.Sc. Thesis Sharif University of Technology ; Daneshgar, Amir (Supervisor)
Abstract
In this thesis, based on the model introduced in [Murphy et. al., Likelihood Estimation for Block Cipher Keys, 1995], we discuss the possibility of unifying the cryptanalysis methods. First, the model for cryptanalysis is discussed and explained by modelling several known statistical attack. In the end, using this model, we propose attacks more general than linear and differential methods
Stability Analysis of High Rise Structures Using the IDA Method
, M.Sc. Thesis Sharif University of Technology ; Khaloo, Alireza (Supervisor)
Abstract
The increased height of high-rise structures has made the effects of reduced stability a crucial factor in structural analysis and design. There are a variety of methods for analyzing the stability of high-rise structures. This thesis discusses nonlinear finite element method for analyzing the stability of a three-dimensional 50-storey concrete structure with a height of 150 meter using increment dynamic analysis (IDA). The IDA was first proposed by Bertero.v and it has been adopted in a variety of manners by researchers. In recent years, this method has been confirmed by EEMA. Moreover, FEMA350, FEMA351 and FEMA P695 guidelines have paid special attention to this method for determining...
