In late 1990, executives, engineers, and financial advisors working for Amoco Corporation and Apache Corporation began serious discussions about the sale to Apache of MW Petroleum Corporation, a wholly-owned subsidiary of Amoco Production Company. Amoco had transferred to MW certain of its own assets that it regarded as non-strategic. MW,s size, location, and operations were all very attractive to Apache, which had grown nearly 30% per year since the mid-1980s

1范围 本方法规定了测定污染水体中阴离子洗涤剂的电位测定法。 本方法采用直接链烷基苯磺酸钠(以下简称AS)作标准物,其烷基碳链的平均数为12, 平均分子量为344.4 本方法适用于测定污染水体中的阴离子洗涤剂。当滴定剂十六烷基溴化吡啶(以下简称 CPB)的滴定度为0.12mg/L时,其测定下限为5mg/L,其测定上限为24mg/L,水样适当稀释, 测定上限可以扩大

Direct determination of the joint probability density of several functions o several ra andom variables Suppose we have the joint probability density function of several random variables x, Y, Z, and we wish the joint density of several other random variables defined as functions xyz

Note n, s enter the system at the same place F is fixed. We design(and perhaps B). We must stabilize F if it is given as unstable

In this problem we will study the effects of adding rules to the rule- base. Suppose that we use seven triangular membership functions on each universe of discourse and make them uniformly distributed in the same manner as how we did in Exercise 2.3. In particular make the points at which the outermost input membership functions for e saturate at +r/2 and for e at tr/4 For u make the outermost ones have their peaks

I. Description of the class: The students are freshmen with the age between 17-21. They are not very active and iastic enthusiastic. As a result, they sometimes can not concentrate on what is going on in class. They

Teaching Objectives: a. to help students to form a picture of Britain when it was under the bombs from German armies during World War II b. to direct students to write a composition with the structure of a general statement supported by specific details c. to guide students to do some oral practice through doing the interview and picture description and the routine pair work as well
