Editor's note: Clothing industry and fashion linked together, this is the most innovative industry, but the beginning of the 2012 has been caught in a dilemma, the reason is very simple-hoarding goods: from Li Ning to the United States, those who have walked in the forefront of the industry suddenly seems to be a negative example. The reason for the emergence of "hoarding goods" lies in the mass production of apparel enterprises, and then forced to "sell" the logic to consumers. The serious lag of garment enterprises production and marketing mechanism, as well as the uncontrolled expansion of brand manufacturers, resulting in a large backlog of products. In the era of scale expansion, the streets are filled with a variety of brand stores, staged a costume ...

Cloud computing scheduling algorithm in meteorological environment Wang Junsong Sheng for the characteristics of meteorological calculation, a cloud model of meteorological calculation is proposed, and a heuristic scheduling algorithm for meteorological cloud Computing (Weather Cloud) is proposed on this model. The scheduling algorithm classifies the meteorological operation according to the time pressing type, the CPU pressing type, the memory pressing type and the hard disk space pressing type, calculates the resource synthesis urgent index, and assigns different scheduling priority rights accordingly. With CMMs (Cloud min scheduling), Afcfs (Adap ...

Apduino CUBE-0 is an experimental project designed to try the sustainable development of small agriculture that can be implemented in the backyard so that anyone can feed themselves. We want to try to get plants to grow in a small, self-contained space for a year or so. At present, we are building a passive solar greenhouse in a closed IBC container and creating a small fish-vegetable symbiotic system. Although at this stage, our "Rubik's Cube" (IBC Container) can only operate under the condition of power, but in the future we hope that with the help of everyone ...
