in this thesis,spin dependend transport and electron transport through of ng/sg(graphene/ superconductor graphen) are studied in the junction of ng/fgt/sg. due to andreev reflection conductance increases in the presence of superconductor graphene.also, by applying a voltage gate on a superconductor, fermi level shifts and the conductance is independent of ferromagnatic substrate. also, the cond...
فرض کنیم c یک زیرمجموعه ی محدب، بسته وناتهی در یک فضای باناخ e و {ُsn} خانواده ای از نگاشت های نامنبسط از c به توی c باشد به طوری که مجموعه نقاط ثابت مشترک خانواده {sn} ناتهی است. دنباله {xn} در c را به ازای هر n ، باx=1x در c xn+1=an f(xn)+(1-an)snxn تعریف می کنیم که در آن ( an}?(0,1 } وf یک انقباض از c به c است. در این پایان نامه شرایطی بر{ an} و {sn} تعیین می کنیم که تحت ان شرایط {xn} همگ...
In the traditional classroom, students learned to depend on tutors for their motivation, direction, goal setting, progress monitoring, self-assessment, and achievement. A fundamental limitation is that students have little opportunity to conduct and manage their learning activities which are important for knowledge construction. e-Learning approaches and applications which are supported by perv...
investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

introduction: a large number of software programs have been used in dentistry for diagnosis and treatment planning to date. however, due to promotion of programming languages and developments in dental sciences, it is necessary to develop and update these softwares. use of softwares for treatment planning for removable partial dentures has been popular for some time and always new softwares hav...
Maintaining healthy behavior among obesity patients is a challenge. This study aims to design an electronic health application for self-care management in collaboration with obesity patients and healthcare personnel.
In this paper, we present a taxonomy for understanding designs and designing of Information & Communication Technologies (ICT) in the field of ‘Social Action’. We use the term ‘Social Action’ to refer to activities of individuals and organisations in civil society, which are oriented towards social (rather than primarily economic) goals. We then apply the term eSocial Action to refer to the app...
