Due to energy shortage and global warming, issues of energy saving have become more important. To increase the energy efficiency and reduce the fuel consumption, waste heat recovery is a significant method for energy saving. The organic Rankine cycle (ORC) has great potential to recover the waste heat from the core jet exhaust of a turbofan engine and use it to produce power. Preliminary study ...

We present a simple, operatingsystem independent method to reduce the number of seek operations and consequently reduce the energy consumption of a hybrid storage device consisting of a hard disk and a flash memory. Trace-driven simulations show that migrating a tiny amount of the address space (0.0001%) from disk to flash already results in a significant storage energy reduction (12%) at virtu...

Energy wasted in buildings is a major fraction of total energy wasted in today’s cities. Most people are not aware of inefficiencies and energy wasted in their homes. Making people aware about energy wasted in their homes and inefficiencies in their energy consumption behaviors could contribute to large energy savings at the city scale. Many energy-saving programs, run by the governments, non-p...

Energy is a very important resource for the development of residential and industrial sectors, it should be used with high efficiency, low environmental impact, at lowest possible cost [...]

The flow distribution of cellular networks fluctuates according to the changes of time and space, and this phenomenon makes the low utilization rate of some base stations. Although the base stations’ utilization rate is low, it causes the large energy consumption. The CSO can save the energy of base stations according to the load, but it is influenced by the load and the sequence of base statio...

Energy consumption for multiple trains on the urban subway line is predominantly affected by the operation strategy. This paper proposed an energy-saving operation strategy for multiple trains, which is suitable for various line conditions and complex train schedules. The model and operation modes of the strategy are illustrated in detail, aiming to take full use of regenerative braking energy ...

Energy resources saving policy in municipal housing economy (MHE) is a priority in the national economy of Russia. It is aimed at reduction of costs for housing stock maintenance and operation and for optimization of housing and municipal services payment system. Suggested in the article is the organizational and economical mechanism of energy resources saving management in MHE, including funct...

Reduced energy consumption in sensor nodes is one of the major challenges in Wireless Sensor Networks (WSNs) deployment. In this regard, Error Control Coding (ECC) is one of techniques used for energy optimization in WSNs. Similarly, critical distance is another term being used for energy efficiency, when used with ECC provides better results of energy saving. In this paper three different crit...

Accurate prediction on energy consumption in machining is helpful to evaluate process energy characteristics and choose process methods for energy saving. Specific energy consumption expresses the required energy consumption when cutting unit volume material. The Back Propagation (BP) neural network prediction method for specific energy consumption in machining is set up in the paper. The predi...

Traditional LCA of central plant hot recycling shows that, the higher RAP added, the less energy consumed. This conclusion is mainly based on the calculation of reduced raw material. However, when the content of Reclaimed asphalt pavement mixture (RAP) reaches some level, it is needed to take measures such as using additive or improved construction method for maintain the performance of asphalt...
