Background and Aim: To understand veterans’ needs and to make future generations familiar with the culture of self-sacrifice and martyrdom, we need a database to store information. The first step for designing a base is to provide a conceptual framework of the base. This study aims to provide a conceptual model to create the national base of veterans in Iran. Materials and Methods: This resea...
The role of spatial data and related technologies in disaster management has been well-known worldwide. One of the challenges concerned with such a role is access to and usage of reliable, accurate and up-to-date spatial data for disaster management. This is a very important aspect to disaster response as timely, up-to-date and accurate spatial data describing the current situation is paramount...
in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
every year, for realizing the goals of five-year state civil development plan, a great part of state credits and financial resources are spent for investment in national projects, whilst most of national projects are performed with considerable delay. essential objectives of applying this research is design and explanaion of national projects managers’ competencies model, focusing on risk that ...
divorce as a social issue in iran has experienced lots of changes during the previous decades. in the present article, these changes are investigated considering the mode of their social development. to state the diverse dimensions of changes in the social structure of divorce in iran, the theoretical “analytic- realistic” model as one of the most efficient theoretical models has been utilized ...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
since esp received universal attention to smooth the path for academic studies and productions, a great deal of research and studies have been directed towards this area. swales’ (1990) model of ra introduction move analysis has served a pioneering role of guiding many relevant studies and has proven to be productive in terms of helpful guidelines that are the outcome of voluminous productions ...
One of the main challenges of disaster management concerns to proper management of information. In more details, while most of the information required for disaster management has spatial component or location, current studies show that there are different problems with collection, dissemination, access and usage of spatial data/information for disaster management. The mentioned problems become...
Spatial scientific research has increasingly become multi disciplinary. The urge of different disciplines to share disciplinary knowledge and information has increased. However, not many Spatial Data Infrastructures (SDIs) have succeeded in facilitating the needs of these multidisciplinary research communities. The article presented offers a methodological framework to develop a user centric SD...
the study discusses the traditional and online procedures and outlines of sdi service. the paper has also taken an initiative to formulate an exact matching technique between user’s subject interest and document profile with exploration along with electronic delivery of voluminous information technique. it also discusses some standard features and model of user profile. finally, the paper explo...
