According to the specifications in IEEE 1894-2015, a transient process measuring device (TPMD) is developed to be used in the distribution system, and a line selection technique utilizing large pulse current is presented on this basis. When a single-phase grounding fault occurs, the distribution system is able to be instantly switched from grounding with small current to grounding with large pulse...
A new method was proposed for enhancing heat transfer between water and refrigerant and making bulk water freezing uniformly by installing three plates with small holes through the coils in the storage tank. This new construction design was applied to a 3HP ice-storage air-conditioning unit using R410A. Experimental investigations were conducted to inspect the performance, including the measurements...
Heat exchange network synthesis has been an effective method in industrial energy recovery system but seldom used in building energy system because of their low enthalpy features. This paper presents a methodology of multi-period synthesis and design optimization of large public building energy system based on pinch analysis concepts and mathematical programming methodology. An updated energy recovery...
In order to assess the `total emission reduction in provincial level', this paper proposes an index system including environment, policy, economy and engineering. And according to the requirement of `veto by one vote', the index weight is decided by analytic hierarchy process and variable weight method, based on which a fuzzy comprehensive evaluation model for emission reduction in provincial level...
Large-scale video surveillance systems typically deploy many video cameras over a wide area and display video streams on separate screens. Operators of this kind of systems have difficulties perceiving the whole pictures of intermixed views and are prone to losing track of targets. This paper presents a surveillance system which integrates videos from multiple cameras into a single comprehensive view...
