Unified Theory and Practice: Polymer Adhesion, X-Ray Diffraction, & X-Ray Florescence By: Frank H. Chung, PhD There are seven adhesion theories scattered in the literature. Each explains adhesion strength loosely in words and figures. The unified theory of polymer adhesion derives a mathematical equation linking bond length, bond energy and bond strength (lb/in 2 ). It unifies and clarifies prior insights into a coherent concept. A set of guidelines is compiled on the effects of functional groups, solvent blends, pigments and filler, adhesion promotion, and the causes of adhesion loss. Due to the complex matrix effects, the quantitative XRD & XRF analyses of mixtures require calibration lines from standard, hence tedious and time-consuming. New insights reveal that both the matrix effects and calibration lines can be eliminated mathematically. A decoding formula applies to both XRD & XRF. One XRD or XRF scan quantifies the chemical elements or compounds in any mixture. The unified procedure reduces about 80% of work current practice with a precision of ± 5% or better.
Concern about psychology’s fragmentation is not new, but there has for the past decade been increasing calls for psychologists to acknowledge to the costs associated with fragmentation and to search for ways to unify the discipline. A New Unified Theory of Psychology introduces a new system that addresses psychology’s current theoretical and philosophical difficulties. The new theory consists of four interlocking pieces that together provide—for the first time—a macro-level view that clarifies the nature of psychology’s problems and offers a clear way to unify the various elements of the field. The unified theory provides the field of psychology with a well-defined subject matter, allowing both academic and professional psychologists will be able to develop a shared language and conceptual foundation.
Unified Theory of Business Strategy (UTBS) Successful businesses require strategic thinking, well-formulated goals and a clear approach to implementation. These are widely accepted as essential to business success. But describing these factors is not the same as making them happen. What corporate executives and business owners increasingly need is a practical, workable approach to business strategy that is supported by theory (but not drowned in it). That is where this book comes in. In Unified Theory of Business Strategy, Dr Rod Samimi combines theory and practice to give readers a solid understanding of how to formulate and implement a pragmatic business strategy. It includes a theoretical framework and applied interpretations, plus a detailed guide for compiling business plans. Using the Sentinel 9 multidisciplinary approach, the book configures an innovative way to look at business strategy.
Unified Signal Theory is an indispensible textbook dealing with the theory of deterministic signals; a topic of fundamental interest to graduates and senior undergraduates in the areas of information engineering (telecommunications, control, systems theory and electronics), astronomy, oceanography, earth science, biology and medicine. The unified theory follows an innovative approach – that of combining all signal classes into just one. The fundamental signal operations (convolution, Fourier transform, linear systems, sampling and interpolation) are established simultaneously for all the signal classes. This unified approach avoids the repetition of similar concepts consequent on other approaches’ separate treatment of definitions and properties for each signal class. Modern wavelet ideas are developed in harmony with the rest of the text. Unified Signal Theory provides: • exercises and examples, to give the student practice; • solutions which are available for download and save the tutor time; and • a choice of two suggested reading paths depending on the level of the student, for an enhanced learning experience. The advantages of the unified approach are many: it permits a global vision of the topic, it is economical in teaching and learning, and it can be adjusted easily to fit new applications. This textbook presents the theory in five chapters, and goes on to demonstrate specific applications such as fast Fourier transform implementation, sampling and reconstructions of signals, and multicolor modulation systems, in a further six chapters. Mathematical concepts are introduced conceptually within the body of the book with more rigorous treatment being reserved for the appendices.
The volume addresses the enormous imbalance that exists between academic interest in politeness phenomena when compared to impoliteness phenomena. Researchers working with Brown and Levinson's ([1978] 1987) seminal work on politeness rarely focused explicitly on impoliteness. As a result, only one aspect of facework/relational work has been studied in detail. Next to this research desideratum, politeness research is on the move again, with alternative conceptions of politeness to those of Brown and Levinson being further developed. In this volume researchers present, discuss and explore the concept of linguistic impoliteness, the crucial differences and interconnectedness between lay understandings of impoliteness and the academic concept within a theory of facework/relational work, as well as the exercise of power that is involved when impoliteness occurs. The authors offer solid discussions of the theoretical issues involved and draw on data from political interaction, interaction with legally constituted authorities, workplace interaction in the factory and the office, code-switching and Internet practices. The collection offers inspiration for research on impoliteness in many different research fields, such as (critical) discourse analysis, conversation analysis, pragmatics and stylistics, as well as linguistic approaches to studies in conflict and conflict resolution.
The proceedings represent a valuable reference on geotechnical problems peculiar to Africa and for engineering solutions to local problems. Topics covered are: Foundation engineering and lateral support; Methods of design and analysis; Monitoring, laboratory and field testing; Municipal, industrial and mining waste and environmental geotechnics; Soil improvement; Transportation geotechnics; Case studies. The proceedings are also an invaluable source of data on the properties of African soils, the properties of residual and tropical soils, as well as climate related problems.
The volume provides a rigorous yet accessible introduction to this emerging area of study.
Communicative visuals, including written text, have a diverse range of forms and purposes. In this volume, the authors show that it is possible to both describe and explain the major properties of diverse visual-communication forms and purposes within a common theoretical framework of information design and ethics. For those unaccustomed to thinking of written text as a visual form belonging to the same general class as other visual forms (colour, texture, shape, imagery, etc.), consider how a text's readability suffers if we remove all white space and punctuation, which can be identified as visual signals of the same subtype as grid lines and bullet points, dividing and calling attention to adjacent information. The authors identify deep connections between foundational visual design elements and the grammar of language itself. No physicist or chemist today questions the value of a single theory that describes and explains a wide variety of phenomena, but oddly enough, the authors have frequently been asked why they are interested in advancing a unified theory of visual communication. The simplest answer is: to treat visual communication as a science, and seeking unified theories is just what science does. In more practical terms, a unified approach to visual communication allows us to teach visual design students relatively few things that will enable them to do relatively many things.
