We present a new topology optimization problem formulation for conjugate heat transfer problems based on minimizing temperature subject to mass flow constraints the of cooling medium and show well-posedness continuum problem. A version augmented with lower bound stiffness designs is considered in numerical examples loosely real design case gas turbine part. The indicate that proposed can be use...

One hundred thirty sleep episodes of 6 subjects, living on a natural 24 hr day, were compared with 116 sleep times of the same subjects living isolated from external time cues. The polygraphic sleep recordings were analyzed for the distribution of REM sleep under both conditions. Additionally, the relationship between body temperature and REM sleep was analyzed by comparing sleep episodes in wh...

This paper presents a systematic method for synthesis of heat exchanger networks, the proposed algorithm consists of three sequential steps to select the optimal approach temperature: i) Estimation of normalized minimum approach temperature, normalized minimum hot utility and normalized minimum cold utility. ii) Fuzzy analogical gates network. iii) Selection of the best weight index. Two analog...
