TL;DR: In this paper, a divide-and-conquer approach is used to generate inter-slice connectivity, and then a case table is created to define triangle topology using linear interpolation.
Abstract: We present a new algorithm, called marching cubes, that creates triangle models of constant density surfaces from 3D medical data. Using a divide-and-conquer approach to generate inter-slice connectivity, we create a case table that defines triangle topology. The algorithm processes the 3D medical data in scan-line order and calculates triangle vertices using linear interpolation. We find the gradient of the original data, normalize it, and use it as a basis for shading the models. The detail in images produced from the generated surface models is the result of maintaining the inter-slice connectivity, surface data, and gradient information present in the original 3D data. Results from computed tomography (CT), magnetic resonance (MR), and single-photon emission computed tomography (SPECT) illustrate the quality and functionality of marching cubes. We also discuss improvements that decrease processing time and add solid modeling capabilities.

TL;DR: The concept of relative deprivation and relative gratification as discussed by the authors are two major concepts relating to the perception of justice and injustice in social exchanges, and both of them can be used to describe the conditions that lead men to feel that their relations with others are just.
Abstract: Publisher Summary The process of exchange is almost continual in human interactions, and appears to have characteristics peculiar to itself, and to generate affect, motivation, and behavior that cannot be predicted unless exchange processes are understood. This chapter describes two major concepts relating to the perception of justice and injustice; the concept of relative deprivation and the complementary concept of relative gratification. All dissatisfaction and low morale are related to a person's suffering injustice in social exchanges. However, a significant portion of cases can be usefully explained by invoking injustice as an explanatory concept. In the theory of inequity, both the antecedents and consequences of perceived injustice have been stated in terms that permit quite specific predictions to be made about the behavior of persons entering social exchanges. Relative deprivation and distributive justice, as theoretical concepts, specify some of the conditions that arouse perceptions of injustice and complementarily, the conditions that lead men to feel that their relations with others are just. The need for much additional research notwithstanding, the theoretical analyses that have been made of injustice in social exchanges should result not only in a better general understanding of the phenomenon, but should lead to a degree of social control not previously possible. The experience of injustice need not be an accepted fact of life.

TL;DR: A special case of Festinger's cognitive dissonance, the theory specifies the conditions under which inequity will arise and the means by which it may be reduced or eliminated as discussed by the authors.
Abstract: A theory of social inequity, with special consideration given to wage inequities is presented. A special case of Festinger's cognitive dissonance, the theory specifies the conditions under which inequity will arise and the means by which it may be reduced or eliminated.
