Emulsion explosive is a form of water in oil emulsions. They include a mixture of fuel and oxidizer and other components. Emulsions are a new type of industrial explosive materials. Because of the stability, high safety and well explosive performance, are used as a powerful and inexpensive source of energy in agriculture, water conservancy, transportation, mining, building materials and etc. So...
Background. Effective kick-topspin serving in tennis requires power to transfer mechanical energy through a kinematic chain from different parts of the body that is directly related to the kinetics of the joints. Energy flow analysis is a powerful tool for observing the mechanical energy transfer through the body parts. Objectives. This research aimed to study the correlation and predictive ab...
PURPOSE Preservative treatments are necessary for disinfection and long term storage when dealing with biological tissue. Freezing is a gold standard but infectious risk can only be eliminated by using chemical fluids that may alter the mechanical properties, depending on their composition. Therefore, we experimentally evaluated the influence of freezing and of two commonly used preservative fl...
In residential section, Studies have shown that, along with the use of various household consumption management techniques, the so-called hubs of energy can also be used to improve the performance and management of home energy management. In each electrical energy system, customers are aiming to minimize their energy costs. In this paper, it can be seen that in each home a home-made residential...
The challenge of electricity distribution’s upgrade to incorporate new technologies is big, and electric utilities are mandated to work diligently on this agenda, thus making investments to ensure that current networks maintain their electricity supply commitments secure and reliable in face of disruptions and adverse environmental conditions from a variety of sources. The paper presents a new ...
The mentioned paper provides a new approach in the design, modeling and evaluation of vanadium redox flow batteries with polymer membrane. Vanadium redox flow batteries have been proposed as one of the advanced technologies in energy storage systems. This study is based on transient conditions of performance modeling of a battery cell. The proposed time-dependent model has developed based on co...
