This thesis research on nutritious balance of specific examples in Chinese recipes applying diversity indices and cluster analysis. Initially, based on data of the nutritional ingredients of food, such as proteins, fat and vitamins, we categorize 1200 kinds of specific food using cluster analysis;then, according to a recipe given by a local restaurant, we calculate and compare the diversity indices based on the components of 25 single dishes in the recipe and analyze the nutritious balance of each dish. 展开更多

Based on the previously published research on the nutritional balance of single recipes based on the fragrance index, this paper proposes a simple diet nutrition balance calculation method based on overlap rate. We calculated and compared the combination of any two of the 25 dishes based on the overlap rate method, which is the nutritional balance of the simple package. We also compared the overlap rate based method and the fragrance index based method for 6 simple packages. The results show that the results of the two methods have certain consistency. We also give a formula for calculating the nutritional balance of a simple package consisting of 3 dishes, which can be extended to a package consisting of more dishes. 展开更多

With the increasing integration of intermittent power sources (IPSs) into the power system, the uncertainty of IPSs requires solution and current dispatch system needs improvement. This paper aims to generate the optimal dispatch plan for day-ahead scheduling and real-time dispatch using the proposed model of characteristic optimal power flow (COPF). The integral time period represented by the median load point and the heavy and light load point with simplicity and accuracy. Simulation case studies on a 30-bus system </span><span style="font-family:Verdana;">are </span><span style="font-family:Verdana;">presented, which shows that COPF is an effective model to generate the optimal dispatch plan for power systems with high penetration of IPSs. 展开更多

Vegetable freshness is very important for both restaurant and home consumers.In market,sellers frequently apply water to leafy vegetables to make them not lose weight and look fresh;however,these vegetables may not be stored for a long time as they appear.After a time limit,they may be quickly rotten.It is thus meaningful to investigate early and simple detection tools to measure leafy vegetable freshness while they are frequently applied water in selling.In this work,three types of newly harvested leafy vegetables were bought from a local farmer market and stored in the air with room temperature and roots submerging in water.Chlorophyll a fluorescence(ChlF)from the vegetables was measured each half a day for three days.The obtained ChlF data were analyzed statistically and the correlation of ChlF parameters and vegetable freshness/storage time was obtained.The k-mean classification was also performed.It is found that Fo,Fj,Fm/Fo,and Fv/Fm can be used as an early detection tool to differentiate the freshness of leafy vegetables on which water is constantly applied in storage without visible difference. 展开更多
