Precision temperature gradient measurements on window glass

Surface temperature gradients were measured with miniature thermocouples installed in a 58.5 cm (23-inch) square window. Test measurements at 25 locations were made under vacuum and with the window operating in radiant heat transfer mode. The analysis of thermocouple design and installation is presented along with a lead wire routing scheme to allow for both differential and absolute temperature measurements while using a minimum number of signal feedthru paths through the test chamber wall. Typical test data and operational precautions are presented along with the accuracy analysis for installation effects and measurement effects to support differential temperature measurement precision values of + or - 0.06 C RMS + or - 0.1 F RMS)

Computer assisted thermal-vacuum testing

In testing complex systems and components under dynamic thermal-vacuum environments, it is desirable to optimize the environment control sequence in order to reduce test duration and cost. This paper describes an approach where a computer is utilized as part of the test control operation. Real time test data is made available to the computer through time-sharing terminals at appropriate time intervals. A mathematical model of the test article and environmental control equipment is then operated on using the real time data to yield current thermal status, temperature analysis, trend prediction and recommended thermal control setting changes to arrive at the required thermal condition. The data acquisition interface and the time-sharing hook-up to an IBM-370 computer is described along with a typical control program and data demonstrating its use

Wilderness experience : a Jungian model

Includes bibliography.The aim of the present study is to produce, and to begin to illustrate the use of, a theoretical model by which varying attitudes to, and experiences of, wilderness may be understood. A classical Jungian developmental framework is utilised for these purposes. The paper begins with brief definitions of the concepts pertinent to this work followed by a fairly comprehensive summary of Neumann's developmental model. The author's model, constructed on this theoretical basis, is then outlined and applied at a mythological level to the attitudes to wilderness manifest in the Judaeo - Christian religions. In the discussion, indications are given as to how the model might be applied at individual and cultural levels. One person's experience of wilderness is interpreted within the context of the theory followed by a brief discussion on the use of the model in informing therapeutic wilderness programming. Traditional North American Indian and contemporary Western attitudes towards wilderness are then briefly interpreted. It is concluded that this paper illustrates the usefulness of a Jungian model in understanding wilderness experience. Within the context of this framework, the value of a developmental perspective is noted

Local‐Regional Similarity in Drylands Increases During Multiyear Wet and Dry Periods and in Response to Extreme Events

Climate change is predicted to impact ecosystems through altered precipitation (PPT) regimes. In the Chihuahuan Desert, multiyear wet and dry periods and extreme PPT pulses are the most influential climatic events for vegetation. Vegetation responses are most frequently studied locally, and regional responses are often unclear. We present an approach to quantify correlation of PPT and vegetation responses (as Normalized Difference Vegetation Index [NDVI]) at the Jornada ARS‐LTER site (JRN; 550 km2 area) and the surrounding dryland region (from 0 to 500 km distance; 400,000 km2 study area) as a way to understand regional similarity to locally observed patterns. We focused on fluctuating wet and dry years, multiyear wet or dry periods of 3–4 yr, and multiyear wet periods that contained one or more extreme high PPT pulses or extreme low rainfall. In all but extreme high PPT years, JRN PPT was highly correlated... (See article for full abstract)
