looking at the structure of the cities, especially older parts of the city, it is seen that most of the urban public parts and elements are constructed not with any reliance on state resources and credits, but based on the consecration systems and public investments. added to the sublime religious, social and economic values latent in the consecration culture, its impact in creating identity an...
This study presents a new approach for physical and material modeling of space frame-raft-soil system. The physical modeling consists of a modified Thimoshenko beam bending element with six degrees of freedom per node to model the beams and columns of the superstructure, a modified Mindlin's plate bending element with five degrees of freedom per node to represent the structural slabs and raft, ...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
We investigate experimentally how children’s increasingly flexible use of reference frames enables accurate search for hidden objects. Children watch as an object is rolled down a ramp, behind a panel of doors, and stops at a barrier visible above the doors. Prior studies have found that 3-year-olds can accurately retrieve the object but that 2-year-olds fail to do so. We gave 2and 2.5-year-old...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
This work is based on the field of reference frames based on quantum representations of real and complex numbers described in other work. Here frame domains are expanded to include space and time lattices. Strings of qukits are described as hybrid systems as they are both mathematical and physical systems. As mathematical systems they represent numbers. As physical systems in each frame the str...
introduction: diabetes mellitus is an growing national and international public health concern. the number of people affected by diabetes in world by 2030 will be 69% in developing countries. regular physical activity plays a key role in the management of type 2 diabetes melitus, particularly glycemic control. it has been recommended that peoples with type 2 diabetes participate in moderate-int...
Encouraging an active lifestyle is an essential part of successful rehabilitation programs, and the link between physical activity and quality of life (QOL) is well established among patients with mobility disorders. Biomechanical aspects of wheelchair design play an important role in physical activity and social participation of disabled individuals. This review focuses on key biomechanical fe...
To program eye-head gaze shifts to sounds, the orientation of eyes and head should be incorporated to specify the target relative to the eyes, and only head orientation should be incorporated to specify the target relative to the head. Here we test whether the eye and head motor systems employ different reference frames for gaze shifts evoked by broadband sounds and pure tones. The head-movemen...
