We study a Fourier-Mukai kernel associated to GIT wall-crossing for arbitrarily singular (not necessarily reduced or irreducible) affine varieties over any field. This is closely related derived fiber product diagram the and simple understand from viewpoint of commutative differential graded algebras. However, perspective algebraic varieties, can be quite complicated, corresponding complex with...

by having daylighting in mind through a building design process rather than end of it, achieving a more sustainable space is much easier and feasible. since many people spend an important amount of their lives at their working spaces, accessing enough natural light together with satisfying view are essential for their physiological and psychological health. moreover as a daylighted space has a ...

in islamic republic of iran, the heating and cooling of buildings account for approximately 40% of total energy use. from the entire energy loss taking place in a building, one third of that energy loss occurs through the windows. many of today’s existing buildings are not energy efficient, and consume more energy than is needed in order to make the working and living environments comfortable. ...

original article     the aim of this study was to design and build a software for noise propagation prediction (indoor and from indoor to outdoor spaces) which is being commonly used in industry.  in this regard, firstly a mathematical complex model was created based on existing relationships about noise propagation in indoor spaces and transmission through the walls and propagation in outdoor ...
