Abstract Bio-oil, produced through fast pyrolysis, can act as an intermediate, which can be further upgraded to biofuels. Fast pyrolysis is done in either a centralized or a decentralized (mobile pyrolysis system [MPS]) system. In a centralized system, biomass is transp...

Abstract Although well logs and core data show that there is significant oil content in Bakken shales, the oil transport behavior in these source rocks is still not well understood. This lack of understanding impedes the drilling and production operations in the shale m...

Abstract Charged particle accelerators were originally conceived and developed to explore the mysteries of atom in particular and to understand the structure of matter in general. Starting their journey since birth about 75 years ago, they have led to several discoverie...

We study the optimal trading policies for a wind energy producer who aims to sell the future production in the open forward, spot, intraday and adjustment markets , and who has access to imperfect dynamically updated forecasts of the future production. We construct a st...

Distributed control and optimization strategies are a promising alternative approach to centralized control within microgrids. In this paper, a multi-agent system is developed to deal with the distributed secondary control of islanded microgrids. Two main challenges are...

Low-bandgap CH$_3$NH$_3$(Pb$_x$ Sn$_{1–x}$)I$_3$ (0 ≤ x ≤ 1) hybrid perovskites (e.g., ≈1.5–1.1 eV) demonstrating high surface coverage and superior optoelectronic properties have been fabricated. State-of-the-art photovoltaic (PV) performance is reported with power con...

Do countries with large energy endowments have larger energy-intensive sectors? We answer this question empirically using a panel with 14 high-income countries from Europe, America and Asia and 10 broad sectors, from 1970 to 1997. Energy-abundant countries have 7 to 10 ...

<p>With the increasing number of migrants and refugees, there is a need for energy-efficient and low impact temporary housing that can accommodate millions of displaced peoples worldwide. This study describes a design proposal for a premium passive refugee house that us...

For the design of future fusion reactors the ferritic-martensitic steel Eurofer97 is the main candidate for in-vessel structural application to be able to withstand harsh environment like irradiation and cyclic loading under elevated temperatures. In case of high temper...

International audience; The purpose of this paper is to describe the relationships existing between the various levels or functions encompassed when designing a Wireless Sensor Network in the specific area of Aircraft Health Monitoring. More precisely, cross dependence ...

Adoption of renewable energy becomes essential for the sake of energy security, increasing crisis of non renewable energy, climate change etc. Global warming, exhaustion and high cost of fossil fuels dictates the practise of alternative sources of energy such as wind an...

In this study, p-type amorphous silicon oxide (a-SiO_x) films are deposited using a radio-frequency inductively-coupled plasma chemical vapor deposition system. Effects of the CO₂ gas flow rate on film properties and crystalline silicon heterojuncti...

Perovskite-based photovoltaics are an emerging solar technology with lab scale device efficiencies of over 22 %, and significant steps are being made toward their commercialization. Conventionally high efficiency perovskite solar cells are formed from high boiling point...

Agroecology can be considered an approach to farming and food systems which integrates the use of ecological principles and biological cycles methods of the traditional systems to the design and management of sustainable agriculture. Despite some differences mainly due ...

Abstract Datasets concerning some user-scale Smart Grids, named Nano-grids, are reported in this paper. First several Solar Home Systems composed of a photovoltaic plant, a backup generator and different types of lithium-ion batteries are provided. Then, the inventory a...

This paper reviews the literature available concerning the energy balance of internal combustion engines operating on alternative fuels. Global warming and energy crisis are among the most important issues that threaten the peaceful existence of the man-kind. More usage...

A measurement calibration method is described in this paper. The proposed method identifies calibration models for the uncalibrated measurements and estimates the calibration model parameters along with the system states. The permanent nature of calibration errors allow...

Abstract The study of hydrogenated amorphous silicon, a-Si:H has become an active and large subfield of growing interest in noncrystalline semiconductors. This paper reviews recent successes as well as difficulties encountered in interpreting some fundamental physical p...

Following Frere and Rietveld's model, correlation constants a and b were determined for many stations in Benin using: •- a graphical relationship between the average annual relative sunshine SS/SS′o and the constants (Frere's model).•- a linear relationship between cons...

Abstract Thin film properties are extremely sensitive to the film preparation conditions, thus our research is dedicated to establish the correlation between the deposition parameters and properties in Al2O3/ZnO bilayered and Al2O3/Al2O3-ZnO mixed oxide/ZnO trilayred th...
