OBJECTIVE The main aim of the current survey was to evaluate a hypothesized model on subjective quality of life (SQOL), and to survey the role of scale anchoring on satisfaction and dissatisfaction ratings. METHOD The sample consisted of 456 volunteering students who were randomly assigned in to two different conditions, and rated their current overall life (dis)satisfaction and their (dis)sa...

The main intention of this paper is to encourage discussion about standards for Petri net le formats. We present criteria for good formats and estimate their signiicance for diierent classes of involved persons. The following persons are considered: 1. the designer of a Petri net tool who should integrate analysis algorithms and editors implemented by diierent persons at diierent locations; 2. ...

Font formats are a tug of war between artists (designers and drawers), programmers (computer scientists), the business world, and users. Each of these four groups has had an influence on the path that font formats have followed. We review the successes and failures, and present a wish list of properties that a good font format should have.

ions, idealisations, and approximations are made in modelling physical systems. This paper will not tackle such issues.

There are a number of color encoding standards that have lately been developed and are being proposed to the imaging community for different encoding steps in the color imaging workflow, optimized for different purposes. In this paper, their applicability for master and derivative image file encoding for image databases is discussed. Several types of image databases are defined, and the advanta...

This paper has been prompted by observations of disparities between the observed fall-off in irradiance fo r off-axis points and that accounted f o r by the cosinefourth and vignetting effects. A closer examination of the image format ion process fo r real lenses revealed that even an the absence of vignetting a point light source does not uniformly illuminate the aperture, a n effect known as ...
