Modern office buildings have high energy savings potential and potential for indoor climate improvements. During the nineties many office buildings with glass facades were built, in several cases with double skin glass facades. The advantages of buildings with double skin facades (compared with single skin glazed ones) are considered to be the reduced heating and cooling demand, the increased soun
The homogenization of the Maxwell equations at fixed frequency is addressed in this paper. The bulk (homogenized) electric and magnetic properties of a material with a periodic microstructure are found from the solution of a local problem on the unit cell by suitable averages. The material can be anisotropic, and satisfies a coercivity condition. The exciting field is generated by an incident field fr
Throughout history packages are used to contain, store and transport goods and products. In early days it was a matter of gathering and storing locally, whereas in today’s global enterprises packaging is an important issue in the operational management in networks of functions and/or divisions, often separated geographically around the world. Packaging has become a part of the process of efficient
Abstract: In order to evaluate physical capacity it is neccesary to choose an appropriate method depending on the condition of the subject being tested and on the purpose of testing. A review has been carried out in order to present some of the protocols for evaluating exercise capacity which are in practical use. Twenty different test protocols for evaluating exercise capacity; 12 cycle protocols
