A comparison of modern and historical methods for calculating Montgomery steamfunction
نویسندگان
چکیده
The suggestion has been made that the Montgomery streamfunction is now calculable for isentropic analysis purposes simply by applying the equation = gZ + cpT . Historically, this practice has been frowned upon, as measurements aloft did not have the accuracy requisite to allow such practice. Instead, an integral approach to calculating has been preferred to get workable values. Yet, advancements in the accuracy of radiosonde measurements have occurred, especially with global positioning system (GPS)-verified height data. Herein, we show that the values from the simple and integral methods of getting are very similar, and differ by only ∼0.2%. Copyright 2013 Royal Meteorological Society

Historical uses of saffron: Identifying potential new avenues for modern research
Objective: During the ancient times, saffron (Crocus sativus L.) had many uses around the world; however, some of these uses were forgotten throughout the history. But a newly formed interest in natural active compounds brought back the attention toward historical uses of saffron. Understanding different uses of saffron in the past can help us finding the best uses at present.In this study, wer...
متن کاملAnalysis and Comparison of Load Flow Methods for Distribution Networks Considering Distributed Generation
Conventional passive distribution networks are changing to modern active distribution networks which are not radial. Conventional load flow methods should be modified for new distribution networks analysis. In modern distribution networks distributed generation (DG) units are embedded with conventional and/or renewable resources. DG units are generally modeled as PV or PQ nodes which inject ...
متن کاملThe Origin and Limitations of Modern Mathematical Economics: A Historical Approach
We have first demonstrated that Debreu’s view regarding the publication of The Theory of Games and Economic Behavior by von Neumann and Morgenstern in 1944 as the birth of modern mathematical economics is not convincing. In this paper, we have proposed the hypothesis that the coordinated research programs in the 1930’s, initiated by the Econometric Society and the Cowles Commission for Research...

Comparative study of modern art in Iran, Iraq, and Pakistan explain aspects of indigenous in modern art. In this article we examine these questions: how did avant-garde artists in these countries attempt to find and match modern art with indigenous art? How did they experience indigenous modernities in art? In this article, by adopting a historical-comparative sociological approach, we analyze ...
