A Study of Lean Body Mass in Estimating Basal Metabolic Rate

Description: The primary purpose of the study was to determine if measured LBM could be used as a more powerful predictor of BMR than could surface area (SA) as calculated by the formula of DuBois and DuBois (1916). It was also of interest to develop a prediction equation for BMR using multiple regression analysis. Data from 82 women and 76 men were included in the study. Pearson product-moment correlations indicated that LBM was a better predictor for BMR than SA on either of the principal SA prediction eq… more

An Investigation of Textural Activity and Its Hierarchical Structures in Selected Works by Krzysztof Penderecki

Description: This study focuses on temporal aspects of the music of Krzysztof Penderecki and deals with these on the level of textural activity. The analyses are based on a referential idea called a "discrete sound event," defined as an occurrence of a sound or collection of sounds which, as a unit, is distinct from the surrounding texture. These sound events are then used to appraise textural activity from layer fluctuation and composite density. The pieces selected for applying these techniques are the Th… more

Swinging Gait Patterns and Preferred Rung Spacing During Free Choice Horizontal Ladder Traverses

Description: Fifty-one subjects each performed two trials which consisted of traversing a horizontal ladder. Film records were made of each trial using a high-speed camera. Absolute and relative temporal and kinematic parameters were obtained from the film records. The conclusions were that there was no age related interaction or differences in preferred rung spacing or contact/airborne times. A Chi-Square analysis did show a preference for a specific gait pattern for the six year old age group.

Computer Graphics Primitives and the Scan-Line Algorithm

Description: This paper presents the scan-line algorithm which has been implemented on the Lisp Machine. The scan-line algorithm resides beneath a library of primitive software routines which draw more fundamental objects: lines, triangles and rectangles. This routine, implemented in microcode, applies the A(BC)*D approach to word boundary alignments in order to create an extremely fast, efficient, and general purpose drawing primitive. The scan-line algorithm improves on previous methodologies by limiting … more

The Object-Oriented Database Editor

Description: Because of an interest in object-oriented database systems, designers have created systems to store and manipulate specific sets of abstract data types that belong to the real world environment they represent. Unfortunately, the advantage of these systems is also a disadvantage since no single object-oriented database system can be used for all applications. This paper describes an object-oriented database management system called the Object-oriented Database Editor (ODE) which overcomes this d… more
