A hot spot of a program is a program region, whose execution time crucially impacts the overall execution time of the program. A hot spot can often be optimized without fully analyzing the whole program. This is supported by approaches for demand-driven data-flow analysis. Particularly successful in practice turned out to be an approach based on reverse data-flow analysis. In this paper, we rec...

in this work, effects of homogenization time of 3 to 13 h at 1200 °c on the grain refinement of as-cast aisi 301 stainless steel after different hot rolling conditions were investigated. the results showed that the minimum grain size of 16±7 mm was achieved when homogenization took place at 1200 °c for 9 h followed by hot rolling at temperature range of 1000–1200 °c with strain of 0.8 and strai...

In this paper, the wear of work roll in hot plate rolling is introduced and the parameters affecting wear mechanisms in hot strip mill are investigated. In addition, different wear mechanisms in hot rolling and the differences between these mechanisms in different stands are explained. Using the finite element method and the rolling equations, a work roll wear model is proposed. Wear is modeled...

Background: Hot flash is considered to be an early and common symptom of menopause. This symptom can interfere with the social and personal life of women; therefore, it demands a secure and effective intervention. Therefore, the present study aimed to determine the impact of black cohosh (Cimicifugaracemosa or actaearacemosa) on vasomotor symptoms in postmenopausal women. Materials and Methods:...

Distortion or bend in a turbine rotor (especially HIP rotors) may be caused by a number of factors, either singularly or in combination. In general, the causes of rotor bend can be classified invariably in two categories: Rapidly forming permanent rotor bends and/or Slower forming rotor bends, which could trip the turbines’ emergency stop. One of the major modifying solutions for rapid repairin...

the effect of hot water treatments [45°c for five minutes, 55°c for 25 seconds and non-treated(control)], salicylic acid in three levels (0, 1 and 2 mm) and calcium chloride in two levels (2% and 4%) on quantitative and qualitative parameters and storage life of pomegranate cv. meykhosh were investigated. experiment was conducted as a factorial based on completely randomized design with three r...

background : we intend to study the inhibitory effect of sulfur compound in ramsar hot spring mineral on tumor-genesis ability of high natural background radiation. objective : the radioprotective effect of sulfur compounds was previously shown on radiation-induced chromosomal aberration, micronuclei in mouse bone marrow cells and human peripheral lymphocyte. ramsar is known for having the high...

the effect of pre-treatments in combination with hot air, vacuum and hot-a microwave drying methods the progress of the drying process, and textural, and colour and rehydration rate on button mushroom (agaricus bisporus) slices were investigated. in this work, one of the following methods: hot air, vacuum drying or microwave-assisted convective drying and also different pre-drying treatments, v...
