Abstract To explore hostile extraterrestrial landforms and construct an engineering prototype, this paper presents the task-oriented topology system synthesis of reconfigurable legged mobile lander (ReLML) with three operation modes from adjusting, landing, to roving. Compared our preceding works, adjusting mode rotations (3R) provides a totally novel exploration approach geometrically matching...

abstract background: in recent years, infrared thermography tools are used for viral disease detection. however, no study has been to evaluate the value of this device. the current study was designed to review the effectiveness of infrared thermography technique for diagnosis of viral diseases in international airports. materials and methods: this study was conducted as a systematic review. all...

Membrane technologies for the separation of mixtures have gained an extensive worldwide attraction in the modern industrialized world. They have many industrial and medical applications such as water desalination, wastewater reclamation, gas separation, food and medical applications. However, even though all these applications have their own efficiency and market, the selection of priority appl...

Background and purpose: An appropriate solid waste (SW) disposal has been a major problem in municipal environment. The use of landfills is the most economical and environmentally acceptable method for the disposal of SWs all over the world. However, landfill leachate can cause environmental issues such as soil and ground water pollution. So, finding suitable land fill site is one of the mo...

Decisions related to system architecture are difficult, because of fuzziness and lack of information combined with often conflicting objectives. We organised an industrial workshop with the objective to choose 5 out of 800 architectures. The first step, the identification of selection criteria, proved to be the greatest challenge. As a result, designers selected system architectures that did no...

Waste management is a complex and detailed process that involves evaluation of certain important factors, such as a geological, geotechnical, hydrological, hydrogeological, climate, urban management, environmental, along with social, cultural, and psychological parameters. Unfortunately, in Iran, there is minimal evaluation of initial parameters and in some cases even don’t exist. The purpose o...
