Spine Preparation: Factors Affecting Optimum Linkage Of Paper And Adhesive In Adhesive Bookbinding, Richard Adams

Theses

Adhesive bookbinding, a method of holding trimmed pages together in a book using hotmelt glue, offers rapid binding and curing time, but has the disadvantage of poor glue penetration into the paper edges. A weak binding will result unless good linkage can be made between paper and glue, which is the objective of spine-roughening treatments. Eight spine-roughening treatments from three manufacturers were compared on an uncoated and a coated paper stock, against a control treatment of trimmed paper. Treatments were studied by light- and scanning electron microscopic examination of paper edges and by measurement of the mean page-pull values based …

Learning System, Bhavesh T. Adani

Theses

Many rule-based learning systems have been implemented which generate and update rules/facts from illustrative examples provided by the user. But very few of them have succeeded in achieving the efficiency and accuracy of an ideal system.

The approach made here is to continuously update the hierarchical structure of rules/facts of a knowledge-base so that efficient and accurate solutions to any query can be achieved easily and immediately from the many possible solutions to the query. As the rule-based systems deal with a very large knowledge-base, it is sometimes necessary to apply a learning technique that finds optimum solutions efficiently.

A Word Based Data Compression Using Arithmetic Encoding, Christopher Dean Peckham

Theses

It is usually difficult to compress data from a statistically unknown source and yield a good compression ratio. Using the fact that words are the fundamental basis of the written language, a data compression scheme based on words should yield high compression ratios. Discussed here is a compression scheme that gathers words from the source stream and places them in a dictionary, or word list, to use later in the coding, thereby becoming adaptive to the words in a given file without prior knowledge of the source. When a word is in the word dictionary, it is encoded by its …
