With the rapid development of sensor technology, various professional sensors are installed on modern machinery to monitor operational processes and assure operational safety, which play an important role in industry and society. In this work a new operational safety assessment approach with wavelet Rényi entropy utilizing sensor-dependent vibration signals is proposed. On the basis of a profes...

Three different mathematical formulations for the scheduling of pumps to minimize energy consumption while still satisfying operational constraints are presented. Each formulation requires the solution of a highly nonlinear optimization problem that requires the iterative solution of an external numerical model for evaluating and satisfying the operational constraints. Two different algorithms ...

In this paper, we develop a new framework to save the data processing energy and extend the operational lifetime of portable video communication devices. Video compression is computationally intensive and energy-consuming. However, portable video communication devices, powered by batteries, have limited energy supply for data processing. One of the central challenging issues in portable video c...

Abstract As a key component of an integrated energy system (IES), storage can effectively alleviate the problem times between production and consumption. Exploiting benefits improve competitiveness multi-energy systems. This paper proposes method for day-ahead operation optimization building-level (BIES) considering additional potential storage. Based on characteristics peak-shaving valley-fill...

Telecommunications industry requires efficient, reliable and cost-effective hybrid power system as alternative to the power supplied by diesel generator. This paper proposed an operational control algorithm that will be used to control and supervise the operations of PV/Wind-Diesel hybrid power generation system for GSM base station sites. The control algorithm was developed in such a way that ...

Accumulation of large quantity of non-biodegradable textile dyes into the environment made much attention to finding a suitable solution for the degradation of textile dyes. In this present study, decolorization efficiency of two different treatment technologies such as Photo-Assisted Chemical Oxidation (PACO – UV/H2O2) and Electrocoagulation (EC) on Reactive ...

We develop analogies between economic systems and thermodynamics, and show how economic quantities can characterize the state of an economic system in equilibrium. We argue that just as a physical system in thermodynamic equilibrium requires a nonmechanical variable ~the temperature T) to specify its state, so does an economic system. In addition, both systems must have a corresponding conjugat...

The energy ramp and the betatron squeeze at the CERN Large Hadron Collider (LHC) are particularly critical operational phases that involve the manipulation of beams well above the safe limit for damage of accelerator components. In particular, the squeeze is carried out at top energy with reduced quench limit of superconducting magnets and reduced aperture in the triplet quadrupoles. In 2010, t...
