sandwich panel with central core honeycomb aluminum as one of the main shielding structures because of their high strength-to-weight ratio and improved energy absorption capacity, has been attracted the attention of many researchers and practitioners in recent years. this paper initiates and presents a new type of central core honeycomb formed by hydroforming process. the study is augmented by ...

Abstract Buildings are responsible for a large amount of greenhouse gas emissions in the world. In order to decarbonize electricity grid and reduce environmental impact building stock, photovoltaic panels can be installed. However, assess PVs, whole life cycle has considered including embodied emissions. Several options photovoltaics exist on market or under development silicon-based panels, th...

0 (assuming an unbiased model), as exploited thoroughly by Deming (1964). The remainder of this article is arranged as follows. First, we describe an annual forest inventory sample design and the construction of a control chart for this design. Next, we present an example of the use of the chart for consideration of the next measurement, and finally we give some recommendations for analysts of ...

Over the years, deployment of distributed energy resources (DER) has risen rapidly with explosive growth in renewable sources (RES), especially using solar photovoltaic (PV) systems and wind power, as well batter...

Indonesia receives a lot of sunlight throughout the year. This then causes large profits to be obtained with Development Solar Power Plant Planning (PLTS) that uses photovoltaic (PV) system. research aims look at how use PV systems as solar power generation system becomes alternative energy in future. The approach used this is qualitative through literature study various previous studies and di...

Solar power generation is usually affected by different meteorological factors, such as solar radiation, cloud cover, rainfall, and temperature. This variability has shown a negative impact on the large-scale integration of energy into supply systems. For successful electrical grid, it necessary to predict accurate panels. In this work, forecasting for two types system (non-transparent transpar...

One of the main challenges in building a Solar Power Generation System at home or Home Plant (Home SPP) is choosing component specifications according to price. The components SPP are photovoltaics (PV) panels, inverters, and wiring systems. Given strict price constraints, selection parts available on commercial market generally low quality. However, low-quality can still provide significant ad...

An experimental program was implemented to investigate the shear transfer mechanism of carbon-fiber-reinforced polymer (CFRP) grids and expanded polystyrene (EPS) rigid foam insulation in three wythe precast concrete sandwich wall panels. The purpose research measure flow capacity observe failure mode(s) panels manufactured with a CFRP grid between wythes. Six were examined by push-out tests wh...

Smart grid is a new approach for electric power grid that uses information and communications technology to control the electric power grid. Smart grid provides real-time control of the electric power grid, controlling the direction of power flow or time of the flow. Control devices are installed on the power lines of the electric power grid to implement smart grid. The number of the control de...

the increase of cell temperature with increased irradiance is probably the mostsignificant disadvantage of using photovoltaic modules equipped with booster reflectors. the aimof this study is to investigate the possibility of improving the performance of a photovoltaic waterpumping system by using a booster reflector and to keep the temperature of pv panels at a lowlevel by cooling pv panels wi...
