Mathematics and the Sciences
The principal thrust of this essay is to describe the current state of interaction between mathematics and the sciences and to relate the trends to the historical development of mathematics as an intellectual discipline and of the sciences as they have developed since the seventeenth century. This story is interesting in the context of the history of present-day mathematics because it represent...
متن کاملMathematics and Statistics in the Social Sciences
Over the years, mathematics and statistics have become increasingly important in the social sciences. A look at the history quickly confirms this claim. At the beginning of the 20 century most theories in the social sciences were formulated in qualitative terms while quantitative methods did not play a substantial role in the formulation and establishment of them. Moreover, many practitioners c...

Evapotranspiration is a central process of the hydrological cycle, and various water saving measures are based on it. However, there is little research work on evapotranspiration in the world. In particular, there is rare hydrological cycle-based research on the impact of channel lining on evapotranspiration in arid and semi-arid regions. This paper applies a hydrological cycle model to examine...

A data mule is a mobile device that can traverse a wireless sensor network field to move near stationary sensor nodes that are spatially dispersed for collecting data from them. Using the data mule can significantly reduce energy consumption of sensor nodes compared to common multihop forwarding schemes. However, it also increases the latency of gathering data of all nodes. In this paper, under...

A newsboy model in which a vendor has a limited budget to procure the required items is developed. It is assumed that the manufacturer will either sell the items to the vendor outright or offer the items to the vendor with return policy. In the latter case, the manufacturer buys back from the vendor the unsold items at the end of the selling season. This study considers one item with budget con...
