with k labelled vertices, where reflection shape consists of all the geometric information that is invariant under compositions of similarity and reflection transformations. The proposed approach embeds the space of such shapes into the space of (k - 1) × (k - 1) real symmetric positive semidefinite matrices, which is the closure of an open subset of a Euclidean space, and defines mean shape as the natural projection of Euclidean means in with k labelled vertices, where reflection shape consists of all the geometric information that is invariant under compositions of similarity and reflection transformations. The proposed ...
It involves two major research tasks, namely: (i) the construction of instruments and procedures for measurement; and (ii) the development and refinement of theoretical approaches to measurement. Those who practice psychometrics are known as psychometricians and although they may also be clinical psychologists, they are not obliged to be so and could instead be (for example) human resources or learning and development professionals. Either way specific, separate, qualifications in psychometrics are required.

Phylogenetic analysis is becoming an increasingly important tool for biological research. Applications include epidemiological studies, drug development, and evolutionary analysis. Phylogenetic search is a known NP-Hard problem. The size of the data sets which can be analyzed is limited by the exponential growth in the number of trees that must be considered as the problem size increases. A better understanding of the problem space could lead to better methods, which in turn could lead to the feasible analysis of more data sets. We present a definition of phylogenetic tree space and a visualization of this space that shows ... market research, surveys and trends
AN OVERVIEW OF KNOWLEDGE DISCOVERY IN DATABASE (KDD) PROCESS ...
         Historically, the notion of finding useful patterns in data has been given a variety of names, including data mining, knowledge extraction, information discovery, information harvesting, data archaeology, and data pattern processing.           The rapid emergence of electronic data management methods has lead some to call recent times as the “Information Age.” Powerful database systems for collecting and managing are in use in virtually all large and mid-range companies — there is hardly a transaction that does not generate a computer record somewhere. Each year more operations are being computerized, ... market research, surveys and trends

market research: Definition from Answers.com
Systematic collection and analysis of data relating to sale and distribution of financial products and services. Market research is an early step in the marketing process, and includes an analysis of market demand for a new product, or for existing products, as well as appropriate methods of distributing those products. Techniques in market research include telephone polling and focus group interviews to determine customer attitudes, pricing sensitivity, and willingness to use delivery alternatives. Most large banks have their own market research departments that evaluate not only products, but their Brick and Mortar branch ... industry trends, business articles and survey research

The mental representation elicited by smelling an odor often consists of multiple sensory and affective dimensions, yet, the richness of this elaboration is difficult to capture using methods to rate the intensity of these factors in isolation. Attempts to use language descriptors for olfactory experience have also been shown to be rather limited; among non-specialists, there is no universally accepted system for describing odors, leading to greater reliance on specific item associations. In this study we explored the utility of semantic differential scaling for illustrating the various dimensions of olfactory experience. 300 ... technology research, surveys study and trend statistics
