Identification and Classification of Common Risks in Space Science Missions

Mitigation of Potential Environmental Risks of Space Nuclear Power Sources (NPS) Missions in International Law

Identification, classification, and evaluation of supply chain risks in concrete dams in terms of cost

Iran is one of the pioneers in dam construction, which dam construction considers one of the greatest industry in Iran. In addition, reducing water sources attract the attentions to dam construction. The process of dam construction, supply of materials, and related services need great financial sources, also dam construction is a time consuming process. Therefore, it is important paying attenti...

Deep space missions and the issue of overcoming the problem of space radiation

As a member of the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS), Iran has a long-term space exploration program. Space radiation is one of the challenges facing humans when they go outside Earth's protective atmosphere and magnetic field. Space is an environment that the cardinal principles of radiation protection i.e. time, distance and shielding cannot be effectively ...

Detection of Fake Accounts in Social Networks Based on One Class Classification

Detection of fake accounts on social networks is a challenging process. The previous methods in identification of fake accounts have not considered the strength of the users’ communications, hence reducing their efficiency. In this work, we are going to present a detection method based on the users’ similarities considering the network communications of the users. In the first step, similarity ...

Physical Investigation of Space, Dosimetry of Space Ionizing Ray Effect (Van Allen belts, Galactic Cosmic Rays and Solar particles) and Plotting Dose Map for Satellite Circular Missions

One of the main factors for satellite design is simulating of total ionizing dose due to space ionizing rays in devices used in space. By measurement of induced dose based on available data in different altitudes, expenses of designing, satellite weight and amount of needed fuel will be reduced. Optimum design of satellite for protecting satellite against ionizing radiation has considerable eff...
