Students using Key to Measurement will experience a variety of hands-on experiences related to the English system of measurement. Group projects are included in addition to numerous individual activities. In Book 1, students learn how a linear measurement system is developed and then do activities related to measuring length. Book 2 focuses on length, perimeter, and area measures. In Book 3, the concept of area is further developed, and students are introduced to volume. Book 4 covers a variety of topics. Students experiment with weighing objects and measuring capacity, and they also learn about temperature and time.Grade: 4-12Format: PaperbackPublisher: Key Curriculum Press

Description:
The p-center problem is to locate p facilities in a network of n demand points so as to minimize the longest distance between a demand point and its nearest facility. We consider this problem by modelling the network as an interval graph whose edges all have unit lengths. We present an O(n) time algorithm for the problem under the assumption that the endpoints of the intervals are sorted, which improves on the existing best algorithm for the problem that has a run time of O(pn).

The outside diameters and thicknesses of the tubes have been selected from ISO 4200. If thicknesses greater than 14,2 mm are needed, they should be choosen from ISO 4200. Specifies the diameters, tolerances and other parameters of tubes. It tabulates conventional masses for austenitic (table 1) and for ferritic and martensitic (table 2) stainless steel tubes. This title may contain less than 24 pages of technical content.

This second edition cancels and replaces the first edition (1977). Specifies the diameters, thicknesses, tolerances and masses per unit length of fired tubes, including superheater and heat exchanger tubes. It does not apply f�r tubes according to ISO 6758 and ISO 6759. Tabulates carbon and alloy steel tubes (table 1), austenitic stainless steel tubes (table 2, ferritic and martensitic steel tubes (table 3)). This title may contain less than 24 pages of technical content.

Applicable to carpets the pile of which consists of uniformly spaced tufts and/or loops. Tufts and loops are defined, and the procedure of determination is specified. - Replaces the first edition (ISO 1763-1973) to which has been added the clause "Conditioning of test specimen", and clause 8 of which has been technically revised. This title may contain less than 24 pages of technical content.

Cancels and replaces the first edition (1972). Specifies a method for the determination of the linear density of all types of yarn in package form. Includes seven optional procedures based on different methods of conditioning and preparation. This method is applicable to single yarns; folded yarns; cabled yarns. Not applicable to yarns which stretch more than 0,5 % when the tension, in centinewtons, per unit linear density of yarn, in tex, increases from 0,5 to 1,0. Not applicable to yarns having a linear density greater than 2 000 tex. This title may contain less than 24 pages of technical content.

For some fabrics, mass per unit length and mass per unit area are related simply by the width of the fabric, but for other fabrics variations in structure may introduce an important distinction between mass per unit length and mass per unit area. The methods are applicable to woven fabrics (including those of "stretch" type) made up full width or folded down the middle, and apply to the determination of the fabric mass of complete pieces as well as of sample length. This title may contain less than 24 pages of technical content.

Gives values of both plain end tubes for general purpose use and precision tubes. Its purpose is to give guidance on the selection of sizes for all activities concerned with the standardization of steel tubes, both nationally and internationally, to serve as a ready reckoner and to avoid the use by different countries of different masses for a tube of the same size. It is not applicable to tubes primarily intended to be screwed. This fourth edition cancels and replaces the third edition (1985), tables 2 and 3 of which have been technically revised by the addition of the outside diameter of 12.7 mm to series 2. This title may contain less than 24 pages of technical content.
