Exploring the Meaning of Quality from Urban Space Users’ Viewpoint by Analyzing Conceptual Environment Codes

The main purpose of urban design is to create good and high-quality urban spaces and environments for people to live while such quality may not be determined only by imposing a structural, perceptual and value system of the designer. It can be said that human and his powers to perceive surrounding environments are the focus of urban design. Having reviewed previous researches and theories in re...

Monitoring the Urban Environment from Space

Monitoring spatiotemporal changes in large urban agglomorations will become increasingly important as the number and proportion of urban residents continue to increase. The synoptic view of urban landcover provided by satellite and airborne sensors is an important complement to in situ measurements of physical, environmental and socioeconomic variables in urban settings. The 10 to 80 m spatial ...

Space Environment and Evaluation of Typical High Altitude Satellite

The space environment consists mainly of high-energy charged particles, such as protons, electrons and heavy ions. They are originating from several sources including galactic cosmic radiation, solar flares and van Allen belts. High energy electromagnetic radiation and neutrons have also been measured on spacecraft. Although shielding can reduce the effect of space radiation it cannot be elimin...

The Space Radiation Environment

The effects of the space radiation environment on spacecraft systems and instruments are significant design considerations for space missions. Astronaut exposure is a serious concern for manned missions. In order to meet these challenges and have reliable, cost-effective designs, the radiation environment must be understood and accurately modeled. The nature of the environment varies greatly be...
