This paper deals with the global ageing behaviour of a polypropylene random copolymer (PP-R) liner material tailor-made primary structure, morphology and stabilization package. Specific focus was given to long-term in welding zones. Conventional weld line testing not feasible due plastic deformation peel arms. Hence, novel approach based on micro-sized specimen implemented used. The PP-R welded...

The Grid Collector is a system that facilitates the effective analysis and spontaneous exploration of scientific data. It combines an efficient indexing technology with a Grid file management technology to speed up common analysis jobs on high-energy physics data and to enable some previously impractical analysis jobs. To analyze a set of high-energy collision events, one typically specifies th...

Smart local energy networks provide an opportunity for more penetration of distributed energy resources. However, these resources cause an extra dependency in both time and carrier domains that should be considered through a comprehensive model. Hence, this paper introduces a new concept for internal and external dependencies in Smart Multi-Energy Systems (SMES). Internal dependencies are cause...

In this paper, emphasis is put on a case study that deals with a system for distributing heat generated in a centralized location for residential and commercial heating requirements. This idea is integrated in the concept called “Energy Hub,” which is a conceptual cluster of local energy converters and storages. It’s supplied by multiple energy carriers coming from an existing grid or from loca...

Dispatch optimization of the integrated energy system with multi-type storages, as an essential issue to optimum management, is a high-dimensional complex nonlinear problem time-series constraints. To overcome problem, new meta-heuristic method presented in this paper. The proposed introduces several heuristic rules, called maximum storage utilization and embeds them into adaptive GA improve qu...

To improve the utilization rate of energy, consumption fossil energy must be reduced. In this study, a low-temperature radiant floor made concrete is taken as research object, and two-dimensional hot water heating system with different filling layers numerically simulated using computational fluid dynamics (CFD) software finite element method. numerical model, sensible heat storage (SHTES) adop...

Wireless sensor networks are deployed in many monitoring applications but still suffer from short lifetimes originating from limited energy sources and storages. Due to their low-power consumption and their on-demand communication ability, wake-up receivers represent an energy efficient and simple enhancement to wireless sensor nodes and wireless sensor network protocols. In this context, wake-...

Output power in a hybrid power system is constant while the input power with variable characteristics that is generated by different sources. Using Hybrid Electrical Energy Storage (HEES) systems, is growing rapidly since there is an obvious need for clean energy. This paper introduces different parts of a HEES system and then proposes HEES systems which employ battery, ultracapacitor and f...
