Like management fashions, there are many IT (information technology) fashions. Testing the extent to which the theory of management fashions apply to IT fashions help us better understand not only IT fashions ...
متن کاملFractal design for efficient brittle plates under gentle pressure loading.
We consider a plate made from an isotropic but brittle elastic material, which is used to span a rigid aperture, across which a small pressure difference is applied. The problem we address is to find the structure which uses the least amount of material without breaking. Under a simple set of physical approximations and for a certain region of the pressure-brittleness parameter space, we find t...

Lameness is an economically important problem in dairy cattle worldwide. Economic losses resulting from lameness arise not only from the cost to treat clinical cases but also from decreased milk production, decreased reproductive efficiency and premature culling.
