Manned simulations of the SRMS in SIMFAC
SIMFAC is a general purpose real-time simulation facility currently configured with an Orbiter-like Crew Compartment and a Displays and Controls (D and C) Subsystem to support the engineering developments of the Space Shuttle Remote Manipulator (SRMS). The simulation consists of a software model of the anthropomorphic SRMS manipulator arm including the characteristics of its control system and joint drive modules. The following are discussed: (1) simulation and scene generation subsystems; (2) the SRMS task in SIMFAC; (3) operator tactics and options; (4) workload; (5) operator errors and sources; (6) areas for further work; and (7) general observations
Microprocessor control of a wind turbine generator
A microprocessor based system was used to control the unattended operation of a wind turbine generator. The turbine and its microcomputer system are fully described with special emphasis on the wide variety of tasks performed by the microprocessor for the safe and efficient operation of the turbine. The flexibility, cost and reliability of the microprocessor were major factors in its selection
Calculus III: Taylor Series
We study functors from spaces to spaces or spectra that preserve weak
homotopy equivalences. For each such functor we construct a universal
n-excisive approximation, which may be thought of as its n-excisive part.
Homogeneous functors, meaning n-excisive functors with trivial (n-1)-excisive
part, can be classified: they correspond to symmetric functors of n variables
that are reduced and 1-excisive in each variable. We discuss some important
examples, including the identity functor and Waldhausen's algebraic K-theory.Comment: Published by Geometry and Topology at

Generation Z’s Proclivity for Technological Communication: An Exploration into its Effects on Employers’ Perceptions of Gen Z and the Intergenerational Workplace
Gen Z’s proclivity for digital communication may be putting them at a disadvantage when shifting into professional settings. Generation Z is inclined to communicate differently than Millennials and Generation Y, the two generations that currently make up the largest percentage of the job market. The idea that Gen Z’s future employers prefer different styles of communication creates the risk of negatively influencing these employers’ perceptions of Gen Z’s professionalism and workplace capabilities. By interviewing 12 internship supervisors from varying industries amidst the Southeast who belong to Generations X and Y, the author explores the difference in communication styles between Generation Z and the X and Y Generations, in order to gain a greater understanding of whether these differences are negatively impacting Millennial and Gen X employers’ perceptions of Gen Z’s workplace potential
A review of data analysis systems
This review gives an appraisal of 8 Automatic Time history reocrd
analysis systems.
The appraisal indicates the analytical capabilities, analysis flexibility
and the cost involved in performing the analysis.
It is suggested that in choosing such a system for an educational
institution, some analysis speed and automation should be sacrificed for
computational flexibility and operational adaptability.
The review does not indicate that a specific machine be considered, but
rather that an analysis system be built from a number of manufacturing sources

Excess nitrogen leaching and C/N decline in the Tillingbourne catchment, southern England: INCA process modelling for current and historic time series
Measurements of nitrate deposition and streamwater chemistry in the Tillingbourne Catchment, in Southern England, made in 1979-1982 and 1999-2001 show a 216% increase in Nitrogen leaching despite a reduction in N inputs. Both the historical and current data sets have been modelled using the Integrated Nitrogen Model in Catchments (INCA). The process-based model is shown to reproduce the historical patterns of N release from the catchment. However, modelling the increased leaching of N during recent years required an increase of the mineralisation control parameter in the model, suggesting enhanced mineralisation rates. Comparing historic and current soils data for C/N ratios shows that there has been a reduction in C/N from 38 to 26% in the humus layer and a reduction from 33 to 26% in the mineral soil horizon. This significant fall in C/N is consistent with the increase in N saturation in the H and Ah horizons of the major catchment soil.</p> <p style='line-height: 20px;'><b>Keywords: </b>acid deposition, recovery, nitrogen, Carbon-Nitrogen ratios, Tillingbourne, Thames, catchment studies, nutrient leaching, modelling</p
Letting Go of Self: The Creation of the Nonattachment to Self Scale
The Buddhist notion of nonattachment relates to an engagement with experience with flexibility and without fixation on achieving specified outcomes. The present study sought to define, create and validate a new measure of nonattachment as it applies to notions of the self. A new construct of “nonattachment to self” (NTS) was developed, defined the absence of fixation on self-related concepts, thoughts and feelings, and a capacity to flexibly interact with these concepts, thoughts and feelings without trying to control them. Two studies were conducted in the development of the new scale. With expert consultation, study 1 (n = 445) established a single factor, internally consistent 7-item scale via exploratory factor analysis. Study 2 (n = 388, n = 338) confirmed the factor structure of the new 7-item scale using confirmatory factor analyses. Study 2 also found the new scale to be internally consistent, with evidence supporting its test-retest reliability, criterion, and construct validity. Nonattachment to self-emerged as a unique way of relating to the self, distinct from general nonattachment, that aligned with higher levels of well-being and adaptive functioning
