Numeric Data

This work tested six techniques for the occasional entry of unstructured numeric data in the context of a primarily mouse-based, cursor-positioning, human-computer dialogue. Two of the techniques used a separate keypad for numeric data entry. The other four techniques used the mouse already being used for the cursor positioning dialogue. The keypad techniques were more efficient than the mouse techniques for all of the numeric sequence lengths considered. There were no significant differences in efficiency between the two keypad techniques. Among the mouse-based techniques, an approach based on a displayed image of a calculator keypad was consistently among the most efficient.

An experiment with 15 U.S. Army enlisted military subjects was conducted to compare the performance of an oculometer, head-fixed reticle, and touch panel for data entry on a generic tactical air combat display. The subjects used voice or switch to designate data items on the display that were selected with the oculometer or fixed reticle. The touch panel was included as a standard data entry device. Statistical analysis showed a significant difference in performance for the five configurations at the .0001 level. The reticle/switch, oculometer/switch, and touch panel are significantly faster than the reticle/voice, which in turn is significantly faster than the oculometer/voice. The reticle methods are faster than the oculometer methods. The switch action is faster than voice entry. The touch panel is twice as accurate as the other methods, all of which have about the same spatial accuracy whether oculometer or reticle, voice or switch. However, the oculometer/voice has nearly twice as many selection errors as the other methods.

Abstract Objective: To test the hypothesis that there is no difference in the shear bond strength of brackets bonded to provisional crown materials (PCMs) using two adhesive agents. Materials and Methods: Four PCMs were tested: Integrity, Jet, Protemp, and Snap. Forty cylindrical specimens of 10 mm diameter × 5 mm were prepared for each PCM. Ten specimens from each group were bonded to one of the two brackets, Clarity or Victory, using one of the two adhesives, Fuji Ortho LC or Ortho Bracket Adhesive. The brackets were debonded in shear at a cross-head speed of 5 mm/min, and the shear bond strength (SBS) was calculated. The type of failure was visually determined. The numeric data were analyzed using three-way analysis of variance and Tukey multiple range test at α = .05. Results: The mean SBSs ranged from 2.81 MPa to 9.65 MPa. There was a significant difference between Snap and the other three materials (P < .0001). There was no significant difference between the two brackets or the two adhesives (P > .05). The bond failure for all the specimens was of the adhesive type between the PCM and the adhesive resin. Conclusions: The PCM Snap yielded a significantly lower mean SBS value compared to the other three materials. No significant differences were found between the brackets or the adhesives. The bond failure was of the adhesive type.

Limited Function

Innovative alphanumeric data entry and edit procedures are required for input-output devices that, constrained by size and usage considerations, are limited to functionality available with multi-character and limited function keys. Such an interface was developed by the authors for Martin Marietta in support of the US Army Single Channel Anti-jam Man-Portable (SCAMP) Program. Two character entry schemes and three message editing protocols were developed and evaluated using a Macintosh-based, Supercard-configured prototype whose conventions were assessed by twelve subjects in a counter-balanced experimental design. One character entry scheme proved to be statistically superior to the other scheme in terms of time and number of keystrokes required, and was universally favored by subjects. Although there was no clearly superior message editing protocol among the three alternatives, one convention was generally favored over the others in terms of performance and ease of operation.

This is a case study of changes successfully made in the job design, workspace layout, and wage payment plan for a very large mail remittance processing facility. The changes were necessitated by excessive musculoskeletal injury and disability claims history, by low morale, and by low production. In addition to the other work changes, programmed exercise breaks for all employees were introduced. Measures of the economic impact of ergonomic changes were made.

The Irrigation Calculator is a computer decision support tool that assists dairy farmers to decide when to irrigate, how much water to apply, and the consequences of wrong irrigation timings or amounts. The user interface has two data entry screens, one to enter background soils information, the other main screen for entering irrigator application times and amounts, grazings and run times.

Current Paradigm

The impreciseness of numeric input data can be expressed by intervals. On the other hand, the normalization of numeric data is a usual process in many applications. How do we match the normalization with impreciseness on numeric data? A straightforward answer is that it is enough to apply a correct interval arithmetic, since the normalized exact value will be enclosed in the resulting “normalized” interval. This paper shows that this approach is not enough since the resulting “normalized” interval can be even wider than the input intervals. So, we propose a pair of axioms that must be satisfied by an interval arithmetic in order to be applied in the normalization of intervals. We show how some known interval arithmetics behave with respect to these axioms. The paper ends with a discussion about the current paradigm of interval computations.

The task of the Sub-Group on Electronic Distribution (SGED) of the Working Group on Astronomical Standards (WGAS) is to make recommendations for direct worldwide computer access to astronomical standards of various kinds. Specifically, part of the charter of the WGAS was ”to prepare a draft report on possible electronic access to these units, constants, quantities, and procedures...”Like the other sub-groups, the SGED operated as a ”committee of the whole”, the whole being the entire Working Group on Astronomical Standards. The scope of interest includes numeric data and software that has some sanction by the IAU or has been validated (in some way) as implementing some IAU-adopted model, set of constants, catalog, ephemeris, or algorithm. Thus, the controversial matters of what defines an IAU standard, whether such standards are still useful, what subject areas are appropriate, what specific standards are to be adopted, how software is to be validated, etc., are addressed by the other sub-groups.
