Spacecraft Trajectory Design Regarding Van Allen Belts by Honey Bee Optimisation Algorithm

Iman Shafieenejad

Articles in Press, Accepted Manuscript, Available Online from 25 July 2023

Abstract
  The aim of this research is to optimize the trajectory of a low-trust spacecraft carrying biological cargo. Reducing the radiation stresses of the Van Allen belt is the optimal criterion of the optimal control problem of the orbital transfer from the low orbits to the high orbits. Since the minimum radiation ...  Read More

Articles in Press, Accepted Manuscript, Available Online from 16 December 2023

Abstract
  The economic model generally expresses the mechanisms used to earn money from a business, and if it doesnot generate income, its failure will be certain. Therefore, the decision to carry out a mission isnot only based on technical specifications, and besides that, economic profitability is another part ...  Read More

The Effect of Extreme Temperature Fluctuations Simulated of Space on the Electrophoretic Profile of Tomato (Lycopersicum esculentum Mill.) Seed Storage Proteins

Fateme Mousavi

Volume 16, Issue 4 , December 2023, , Pages 83-89

Abstract
  Seed aging is a process that can lead to a complete loss of seed viability. This process occurs when seeds are exposed to long-term storage or controlled deterioration treatments such as excessive dryness, lack of oxygen, and temperature fluctuations on Earth or in outer space. Proteomic changes can ...  Read More

Determination of the density of scattered spherical data for use in star catalog uniformity

Farshad Somayehee; Amir Ali Nikkhah; Jafar Roshanian

Volume 14, Issue 2 , June 2021, , Pages 103-110

Abstract
  In this paper, a new algorithm for determining the density of scattered data at the surface of the sphere is presented and then the proposed algorithm along with Geodesic Weighted K-Means clustering and Deluany triangulation are used to make uniform star catalogs. Comparison of the results with the results ...  Read More
