In China, coal combustion to generate electric power is the primary method, the energy-saving and emission reduction is the urgent task. At present, the energy-saving dispatching trial method in some area evaluates energy-saving and emission reduction of coal combustion power generation according to power supply coal consumption rate only. But the power supply coal consumption rate can’t reflec...

One of the industries with high potential for energy saving is the petrochemical industry. Ethylene and propylene production plants (olefin plants) – as a part of the petrochemical industry – are very energy intensive. So, any try to improve their energy consumption efficiency could lead to a high amount of energy saving. Iran’s petrochemical industry uses old technologies and components and du...

One of the subjects in solar water heater design is considering distribution of hot water consumption during the day. For example, each of the household, commercial, office, school, and industrial consumptions have a particular distribution of hot water consumption named pattern in this article. In solar computation principles, the effect of longitude, latitude, and altitude on collector angle ...

Time Saving and energy consumption has become a vital issue that attracts the attention of researchers in Underwater Wireless Sensor Networks (UWSNs) fields. According to that, there is a strong need to improve MAC protocols performance in UWSNs, particularly enhancing the effectiveness of ALOHA Protocol. In this paper, a time-saving Aloha protocol with slotted carrier sense proposed which we c...

Can Subjective Mortality Expectations and Stated Preferences Explain Varying Consumption and Saving Behaviors among the Elderly? This study investigates how subjective mortality expectations and heterogeneity in time and risk preferences affect the consumption and saving behavior of the elderly. Previous studies find that the large wealth disparities observed among the elderly cannot be explain...
