BACKGROUND The future hydrogen economy offers a compelling energy vision, but there are four main obstacles: hydrogen production, storage, and distribution, as well as fuel cells. Hydrogen production from inexpensive abundant renewable biomass can produce cheaper hydrogen, decrease reliance on fossil fuels, and achieve zero net greenhouse gas emissions, but current chemical and biological means...

Composite coiled tubing is an emerging technology in the oil & gas sector that presents important advantages compared to the steel coiled tubing and conventional drilling. The composite tube has reduced weight, allowing extended reach and improved fatigue life. An additional advantage resides in the fact that the coiled tube wall can contain and protect additional functional elements, such as e...

Efficient energy storage in distributed energy systems depends on the operation of a set of coordinated devices spread around the power system. These include not only storage devices, but also production and consumption devices. Usually these devices encompass some communication skills and are able to be operated by energy management systems, regarding the status of the power system. However, d...

plants cover composition, condition, trend, production, and grazing capacity of the rangeland change annually. in this research, the role of temporal rainfall distribution on rangeland production was assessed. this research had down in the rangelands of ilam (with semiarid to semi humid climate) and qom and markazi (with arid to semiarid climate) provinces. by attention on plant cover maps in e...

Mammalian expression systems, due to their capacity in post-translational modification, are preferred systems for biopharmaceutical protein production. Several recombinant protein systems have been introduced to the market, most of which are under clinical development. In spite of significant improvements such as cell line engineering, introducing novel expression methods, gene silencing and pr...

Parallel algorithms for the approximation of a multi-dimensional integral over an hyper-rectangular region are discussed. Algorithms based on quasi-Monte Carlo techniques are compared with adaptive algorithms, and scalable parallel versions of both algorithms are presented. Special care has been taken to point out the role of the cubature formulas the adaptive algorithms are based on, and diffe...

The Robert-Asselin (RA) time filter combined with leapfrog scheme is widely used in numerical models of weather and climate. It successfully suppresses the spurious computational mode associated with the leapfrog method, but it also weakly dampens the physical mode and degrades the numerical accuracy. The Robert-Asselin-Williams (RAW) time filter is a modification of the RA filter that reduces ...

In this paper, a mathematical model for a general integrated lot-sizing and cutting stock (GILSCS) problem is proposed. This model considers multiple dimensions of integration and comprises several aspects found in practice, and as such enables us to classify the current literature in this field. The main classification of the literature is organized around two types of integration. In a planni...
