Boundary of the square

PM2.5 is the particulate matter with aerodynamic diameter of 2.5 µm or less, which is the root cause of haze event. Although there is no detailed standard for haze episode, haze is generally defined as a phenomenon characterized by visibility of ~8km, high concentration of particulate matter, relative humidity of less than 90%, following by certain weather conditions of very low wind speed of < 1 m/s and suppressed planetary boundary layer height.

In this research, we investigated the effects of positions and sizes of entrance on the water flow in a rice field. We proposed mathematical models with three different designs of entrance on the rice field of 2301 square meters. The flow in the models is described by continuity and Navier-Stokes equations. The models are solved by finite element method in a 2D system with three positions of the entrance: left, right and central of the rice field for the entrance of 0.25 meters wide, 0.5 meters wide and 1 meter wide, respectively.

The remains of pueblo architecture are found scattered over thousands of square miles of the arid region of the southwestern plateaus. This vast area includes the drainage of the Rio Pecos on the east and that of the Colorado on the west, and extends from central Utah on the north beyond the limits of the United States southward, in which direction its .boundaries are still undefined.

The dry-farm territory of the United States stretches from the Pacific seaboard to the 96th parallel of longitude, and from the Canadian to the Mexican boundary, making a total area of nearly 1,800,000 square miles. This immense territory is far from being a vast level plain. On the extreme east is the Great Plains region of the Mississippi Valley which is a comparatively uniform country of rolling hills, but no mountains. At a point about one third of the whole distance westward the whole land is lifted skyward by the Rocky Mountains, which cross the country from south to...

Computing has become a necessary means of scientific study. Even in ancient times, the quantification of gained knowledge played an essential role in the further development of mankind. In this chapter, we will discuss the role of computation in advancing scientific knowledge and outline the current status of computational science. We will only provide a quick tour of the subject here. A more detailed discussion on the development of computational science and computers can be found in Moreau (1984) and Nash (1990).
