Deformation monitoring with total stations, while superior in accuracy, suffers from the poor spatial resolution obtainable by this measurement method within the limited time on a tunnel construction...
Recent development of airborne laser scanner systems allows for digitization and recording of the full-waveform, i.e. the received signal of the reflected laser pulse. In this paper, some visualizat...
Renewable energy sources are major components of the strategy to reduce harmful emissions and to replace depleting fossil energy resources. Data from remote sensing can provide information for multi...
Wind Field Analysis Around A Horizontal Axis Wind Turbine.
Wind Turbine Blade Stress Analysis And Natural Frequencies.
Wind Turbine Design, Performance, And Economic Analysis.
An exergetic analysis of three basic types of solar drying systems is presented. The analysis is used to find the available useful energy and the quality of energy that is obtainable from the dryers. ...
In this paper a multidisciplinary methodology for analyzing the opportunities for exploitation of open-loop groundwater heat pump is proposed. The approach starts from a model for calculation of a tim...
Maintaining minimum depth in conventional basin type solar still is difficult, as the area is large. However this can be achieved in stepped solar still in which the area of the basin is minimized by ...
Cooling tower is an open system direct contact heat exchanger, where it cools water by both convection and evaporation. In this paper, a mathematical model based on heat and mass transfer principle is...
The performance of a new design of batch solar water heater has been studied. In this system, the collector and storage were installed in one unit. Unlike the conventional design consisting of small d...
根据生物质可压缩性以及成型物具有一定硬度等特点,将生物质成型过程看成非线性有限元问题。建立力学模型,利用ANSYS软件分析成型过程中的静水压应力、等效应变以及载荷与形变的关系,提出分段填料压缩可提高成型物的耐久性,采用缓慢压缩和提高物料的软化程度等方法可以防止成型物出现裂纹。
The Middle East and African oil have now accounted for 70% of China’s total oil imports and will have to be China’s major sources of crude oil imports in the future, which means that Beijing will cont...
