A Tutorial on Analog Computation: Computing Functions over the Reals

According to the micro-climate environment outdoor of the region, wind environment outdoor which is under planning programming can be done analog computation using computational fluid mechanics PHOENICS software. A set of comprehensive prediction and assessment system which is mainly focused on outdoor environment composite index WBGT can be established combining with assessment method on wind environment outdoor of predecessors in order to more accurately and humanly predict and assess the wind environment outdoor, bring safe, comfortable and healthy outdoor environment and provide references for the assessment and design of green residential district.

High Degree

Generalized integration is a technique for generating ex plicit functions on an analog computer by solving the appropriate differential equations they satisfy. Setting up the solution of differential equations using the parametric technique is first reviewed. Two theorems regarding the capability of linear equipment in generating sums and products are stated, and their usefulness is illustrated with examples. Applications of the technique to generating high-degree oscillatory polynomials and rational functions (which require nonlinear equipment) are also described. The major advantage of the technique is achievement of great accuracy with minimum equipment in some cases. The major disadvantage is that, with time, errors may sometimes increase and may not be bounded.

In the Fall of 1965, it was decided that an existing facility of adjacent analog and digital computers would be up graded to provide hybrid computation capability. The Mermaid Monitor System, which provides the executive control functions and hybrid communications features, was developed in the very brief period during which the interface equipment was built. The initial version of Mer maid was written by digital systems programmers with no direct experience with analog computation who consulted with analog programmers with no digital or hybrid expe rience. Despite the general lack of knowledge and expe rience, the initial version was a workable monitor system which was used for over a year. Since the initial version of Mermaid was not an ideal monitor, a two-stage updating was undertaken to incor porate additional equipment and to strengthen Mermaid's capabilities in the area of hybrid inputloutput. On com pletion of this development cycle, the system will be com pletely disk oriented, and it will provide a maximum of convenience in programming for hybrid applications.
