Hybrid system based on photovoltaic is considered an effective option to electrify remote and isolated areas far from grid. This is true for areas that receive high averages of solar radiation annually. Using diesel generator as a standby source will make utilization of hybrid systems more attractive. An economic feasibility study and a complete design of a hybrid system consisting of photovolt...

Power quality issues are becoming increasingly important due to the rapid changes in energy network infrastructure caused by technological advancements distributed generation. Distributed generation involves use of small-scale, decentralized power sources that can be located close end-users, and include solar panels, wind turbines, fuel cells. While help reduce greenhouse gas emissions increase...

nowadays, tetrapack packaging materials are widely used in beverages such as juice, milk and water packaging applications. each year a significant amount of waste is producing in the world which are non-recyclable in other industries and will also cause environmental pollution. this paper outlines the panels made from tetrapack waste and investigation of physical and bending properties of these...

One of the challenges in pharmacological screening is to maximize the throughput of tests in order to evaluate the potential efficacy of a large number of compounds in a minimal amount of time. The inhibitory avoidance test, also called passive avoidance, has long been used as a screening test to evaluate drug effects on the memory in rodents [1,2]. The test is based on the natural photophobia ...

This paper presents several advancements in the use of fiber reinforced polymer (FRP) materials for the precast concrete industry. Precast concrete members are commonly selected for reasons such as the high level of quality control used in their production, the durability of the finished structure, reduced labor costs and shorter construction schedules, and the economics of scale achieved with ...

In block-partitioned parallel matrix factorization algorithms, where the matrix is distributed over a logical torus processor grid with an rs block-cyclic matrix distribution, the greatest scope for optimization exists in the formation of (block) panels. Let ! be the panel width, with ! m being an optimal value based on the characteristics a single processor's memory hierarchy. To date, two wel...

with speed increasing in high-speed trains, due to limitations of other types of brakes, aerodynamic brake has become an important braking method. in this task to make better use of brake’s panel different configurations are examined and the best panel shape which provides the reasonable drag coefficient is introduced. the results of simulations are carried out with the computational fluid dyna...

Autonomous photovoltaic panels are intermittent sustainable energy sources which require energy storage to balance generation and demand, as photovoltaic generation is time and weather dependent. Traditionally batteries are the most common storage technology for photovoltaic systems. Photovoltaic batteries can encounter extended periods of low State of Charge (SOC), resulting in sulphation and ...

The mechanical response and fracture of metal sandwich panels subjected to multiple impulsive pressure loads (shocks) were investigated for panels with honeycomb and folded plate core constructions. The structural performance of panels with specific core configurations under multiple impulsive pressure loads is quantified by the maximum transverse deflection of the face sheets and the core crus...

aluminum foams are a novel branch of advanced materials with superior properties. sandwich structures with aluminum foam core are good energy absorbers. in this paper, mechanical properties and energy absorption of aluminum foam sandwich panels subjected to quasi-static perforation tests with conical-nosed indenter were investigated experimentally. for this purpose sandwich panels consisting of...
