Abstract Recent experimental studies have shown that a sequence of low-energy electrical far-field pulses is able to terminate fibrillation with substantially lower per-pulse energy than single high-energy electric shock (see S Luther et al Nature 475 235–39). During this antifibrillation pacing (LEAP) procedure only tissue near sufficiently large conduction heterogeneities, such as coronary ar...

abstract: nowadays due to developing the information technology, buildings are equipped to this technology in order to reduce energy consumption and make more convenient for inhabitants. the popularity of smart home has been increasing greatly in recent years due to much higher affordability and simplicity through android smartphone connectivity. this paper prepares a review of smart home and h...

Energy per Instruction (EPI) is a measure of the amount of energy expended by a microprocessor for each instruction that the microprocessor executes. In this paper, we present an overview of EPI, explain the factors that affect a microprocessor’s EPI, and derive a historical comparison of the trends in EPI over multiple generations of Intel microprocessors. We show that the recent Intel® Pentiu...

The main purpose of this paper is to analyze the energy production in the Maltese islands, focusing on the employment of renewable energies in order to increase their energy independence. The main renewable source here proposed is wave energy: thanks to a strategic position, Malta will be able to produce electrical energy using an innovative type of Wave Energy Converter (WEC) based on the prot...

We propose a quantum Hamiltonian for a transmission line with charge discreteness. The periodic line is composed of an inductance and a capacitance per cell. In every cell the charge operator satisfies a nonlinear equation of motion because of the discreteness of the charge. In the basis of one-energy per site, the spectrum can be calculated explicitly. We consider briefly the incorporation of ...

The amount of electrical energy produced over the lifetime of coal, LWR fission, DTfusion, and wind power plants is compared to the total amount of energy required to procure the fuel, build, operate, and decommission the power plants. The energy payback ratio varies from a low of 11 for coal plants to a high of 27 for DT-fusion plants. The magnitude of the energy investment and the source of t...

The use of renewable energy sources is one of the most relevant goals to be achieved in order to match the climate protection targets. As a case study, the paper shows the current electrical energy production by sources in the Sicilian context. Among the renewable energy sources, the paper investigates the wave energy potential along the Sicilian coasts, because of the favorable climate around ...
