Geometry Learning

As a fundamental science of forms and their order, geometry contributes to the process of composing and designing of products. Geometry is able to make a contribution to these processes by dealing with the geometric figures and forms as design elements as well as the relations between them. Finding the general principles of successfully combining those elements was a research aim of many designers, such as those in the modernist era. Influencing the industrial design in a revolutionary way, the Modernism became significant artistic movement of the 20th century, thus giving us the most iconic and timeless product designs. In this scientific paper, the relationship between geometry and design in the Modernism is described and explored through examples, with emphasis placed on De Stijl and Bauhaus products. Direct comparison is applied, focusing on the similarities and differences in the products’ geometry. Learning about the geometry and how it relates to the designs is not to be used as a substitute for the creative process, but rather as a means of obtaining a deeper understanding of it.

The Relationship

The acoustic reflex threshold (ART) was studied in 544 ears having hearing levels (ANSI-1969) ranging from 0 to 110 dB HL. The activating signals were pure tones (500, 1000, and 2000 Hz) presented at levels up to 125 dB HL. The results indicated that the ART increased with hearing loss beyond certain levels. The proportion of absence of reflex responses depends upon the degree of hearing loss, test frequency, and the limits imposed by the instrumentation. Absence of reflex responses is rare for hearing losses of less than about 80 dB HL when the hearing loss is attributable to cochlear involvement.

The Relationship

Modern methods of image analysis are based on the coordinates of the points making the silhouette of an image and allow the comparison between seed shape in different species and varieties. Nevertheless, these methods miss an important reference point because they do not take into consideration the similarity of seeds with geometrical figures. We propose a method based on the comparison of the bi-dimensional images of seeds with geometric figures. First, we describe six geometric figures that may be used as models for shape description and quantification and later on, we give an overview with examples of some of the types of seed morphology in angiosperms including families of horticultural plants and addressing the question of how is the distribution of seed shape in these families. The relationship between seed shape and other characteristics of plant species is discussed.

Reference Threshold

The problems inherent in using frequency-specific stimuli in the sound field to determine threshold sensitivity are reviewed, including a discussion of some of the specific problems encountered when introducing pure tones, narrow bands of noise, and frequency-modulated (FM) tones. The results of two experiments are reported. In Experiment I, the relationship between pure tones and frequency-modulated tones is developed under earphones in an anechoic chamber, and in two sound-isolated auditory test rooms (not anechoic). Experiment I resulted in the development of a reference threshold sound pressure level for frequency-modulated signals in the sound field. In Experiment II the reference level was applied to a clinical test facility and evaluated with a group of hearing-impaired individuals. The results suggest that the sound-field reference levels accurately reflect monaural threshold under earphones, when the earphone is calibrated to the ANSI, 1969 standard, and the sound field is calibrated to the suggested standard.

The Relationship

The prediction of SRT for spondees from pure-tone thresholds is considered in two ways. First, review of statistical studies on the relationship between sensitivity for pure tones and SRT for spondees shows their results to be inconclusive and confusing for the clinician except to demonstrate that frequencies outside the 500–2000 Hz range are of minimal importance in estimating SRT. Second, regression equations derived from two new, audiometrically heterogeneous groups reveal that 500 and 1000 Hz carry primary and nearly equal importance as predictors of SRT when audiometric contour is not taken into account. The clinician must bear in mind that any prediction he makes must incorporate a correction constant, which will vary with the calibration of his audiometers and other variables. A reasonable general formula for predicting clinical SRTs for spondees from pure-tone thresholds when audiometric contour is not taken into account and when the testing equipment is calibrated to the new ANSI threshold reference levels is:

The Relationship

A review is given of information on the galactic-centre region obtained from recent observations of the 21-cm line from neutral hydrogen, the 18-cm group of OH lines, a hydrogen recombination line at 6 cm wavelength, and the continuum emission from ionized hydrogen.Both inward and outward motions are important in this region, in addition to rotation. Several types of observation indicate the presence of material in features inclined to the galactic plane. The relationship between the H and OH concentrations is not yet clear, but a rough picture of the central region can be proposed.
