Sommario/riassunto |
|
Hydroxyacetophenones constitute the starting material for a wide variety of syntheses in organic chemistry. They are versatile building blocks serving many different applications, such as specialty polymers, pharmaceuticals and fine chemicals. In this Handbook the diverse ways of obtaining over 3000 hydroxyacetophenones are described and their physico-chemical properties and spectroscopic data references are indicated. The Handbook is presented in dictionary style, with a logical classification of the ketones, making the information easily available for consultation. Ketones are classified methodically. They are thus easily accessible from three tables: the molecular formula index the chemical abstracts registry the usual names index. This completely revised and enlarged edition includes: 10 additional chapters compared with the previous edition which had just 2 chapters an additional 1500 ketones updated information for ~1200 ketone entries the addition of di- and polyketones approximately 3500 references. This Handbook is the reference on hydroxyacetophenones. It is a powerful synthesis tool for the researcher or industrial producers. Nowhere else are so many compounds covered or the physical properties and relevant syntheses provided. It provides a wide choice of hydroxyketones required to |

Sommario/riassunto |
|
This book discusses human emotion recognition from face images using different modalities, highlighting key topics in facial expression recognition, such as the grid formation, distance signature, shape signature, texture signature, feature selection, classifier design, and the combination of signatures to improve emotion recognition. The book explains how six basic human emotions can be recognized in various face images of the same person, as well as those available from benchmark face image databases like CK+, JAFFE, MMI, and MUG. The authors present the concept of signatures for different characteristics such as distance and shape texture, and describe the use of associated stability indices as features, supplementing the feature set with statistical parameters such as range, skewedness, kurtosis, and entropy. In addition, they demonstrate that experiments with such feature choices offer impressive results, and that performance can be |
|
|
|
|
|
|
|
|
|
|
further improved by combining the signatures rather than using them individually. There is an increasing demand for emotion recognition in diverse fields, including psychotherapy, biomedicine, and security in government, public and private agencies. This book offers a valuable resource for researchers working in these areas. |
