One of the most challenging issues in modern-day building energy management involves equipping the buildings with more energy efficient facilities. In this paper, a hybrid system for cooling/heating for a residential building is developed and optimized. The system consists of a ground source heat pump (GSHP) as well as an electric chiller (EC) and boiler. The model is implemented in MATLAB ...

BACKGROUND Costs and potential benefits of an intensive chest X-ray (CXR) screening program to detect asymptomatic pulmonary metastases in patients with intermediate-thickness, local, cutaneous melanoma were assessed. METHODS Cost-effectiveness analysis from a societal perspective was performed using data on recurrence detection from an historic cohort at Roswell Park Cancer Institute and oth...

a hybrid hydro/wind/photovoltaic base on hydrogen storage system is designed to supply power demand of pump stations. the aim of this design is minimization of net present cost of the hybrid system. optimization problem is subject to reliable supply of the demand. the system is investigated in the north west of iran (meshkinshahr) and the local data is applied. about 12 pump stations are found ...
