Energy efficient manufacturing from machine tools to manufacturing systems
Energy efficiency is one of the key drivers for sustainability. Within manufacturing environments, energy efficiency importance has grown, and it is now considered among other decision-making factors such as productivity, cost and flexibility. However, in most cases the energy consumption of the various components of the manufacturing systems, such as machine tools, are considered using average...
متن کاملEnergy-Efficient Random Access for Machine- to-Machine (M2M) Communications
In this paper, an average consumed energy for a unit data transmission in analyzed in frequency-agile cognitive radios. The average energy consumed by a random access protocol operated in a channel using a whole system bandwidth is compared with that operated in frequency-separated channels, which results in an energy saving ratio. The energy saving ratio quantitatively evaluates an energy savi...
متن کاملTowards a generalized energy prediction model for machine tools.
Energy prediction of machine tools can deliver many advantages to a manufacturing enterprise, ranging from energy-efficient process planning to machine tool monitoring. Physics-based, energy prediction models have been proposed in the past to understand the energy usage pattern of a machine tool. However, uncertainties in both the machine and the operating environment make it difficult to predi...
متن کاملEnergy-Efficient Acceleration of MPEG-4 Compression Tools
We propose novel hardware accelerator architectures for the most computationally demanding algorithms of the MPEG-4 video compression standard-motion estimation, binary motion estimation (for shape coding), and the forward/inverse discrete cosine transforms (incorporating shape adaptive modes). These accelerators have been designed using general low-energy design philosophies at the algorithmic...
متن کاملAvailability-Aware Energy-Efficient Virtual Machine Placement Algorithm
—Availability, as a part of Service Level Agreement (SLA), is a critically important issue in cloud services, which are affected by server or network failures in datacenters. Cloud service providers seek to not only fulfill the SLA, but also simultaneously minimize their operating costs, which are dominated by the energy consumption. In order to minimize the impact of a server/switch failure o...
