Simulated Match

Every simulation requires a good static check to be performed to insure that,initially, the equations being simulated match those of the analysis and, subsequently, to be sure that the analog computer's patchboards remain free from wiring errors. Custom arily the static check is prepared by hand using a desk calculator, since the time required for pro gramming a "one-shot" digital program is typically not a good investment. However, by utilizing the capabilities of a suitable simulation language (such as CSMP or DSL/91), digital static checks can be made economically in less time than that required for a hand-calculated check, especially in the case of hybrid computations. Also, with a little ingenuity, the efficiency of hybrid simulation can be greatly increased by combining the static-check calculation and automatic analog setup via the simulation-language static check. (Familiarity with analog programming and the use of simulation languages is assumed.)

Original Survey

This simulation language survey is a followup of the survey published in SIMULATION, in May 1970, p. 225. The previous report generated much inter est, criticism pro and con, and most importantly some additional responses. Consequently the responses summarized below, including the 30 re sponses from the original survey, now total 103. Responses were solicited by direct request, the generous efforts of others (notably Ira Key of Southern Simulation Service, Inc.), and a "Dear John" letter published in the October 1970 issue of SIMULATION.

Digital Computers

The advent of high‐speed digital computing machines requires extrapolation and interpolation methods which do not involve central differences and time‐consuming tabular information. Extrapolation and interpolation formulae meeting these requirements are developed. These formulae are applicable to the desk calculator as well as to punched‐card programming systems for electronic‐digital computors. Some applications of the usefulness of these formulae are noted in connection with the preparation of gravity and magnetic maps. Their usefulness may likewise be extended to other types of geophysical and experimental data where the time required to obtain computed results is an economic factor.

Real progress has been made by the SCi Committee on Simulation Software in their attempt to specify a "stand ard" language for the digital simulation of continuous systems. Their success, as indicated by the discussion dur ing the Hybrid Software Standardization Seminar at the SNSCi Meeting in Boston, surprised many who thought that the Committee was attempting to satisfy everybody- a proverbially impossible task. The SCi Committee on Simulation Software grew out of a general feeling that some sort of direction was needed in the area of "digital simulation languages". For many people, this feeling was crystallized by Brennan and Line barger's article "A survey of digital simulation ..." (Vol ume 3; Number 6, page 22, December 1964). The riot of invention duplicated effort and apparent neglect of good ideas indicated the need for some guidance and control! Most of the developers of important simulation lan guages joined in the committee work. They met at rather frequent intervals, maintained effective communication through correspondence, and at length reached a con sensus on principles and concepts. The detailed specifica tion of a continuous system simulation language was then delegated to a working subcommittee. They are now preparing a document, the subcommit tee's report, which will be modified and approved by the entire Committee on Simulation Software.

The advent of the scanning electron microscope (SCEM) has renewed interest in preparing specimens by avoiding the forces of surface tension. The present method of freeze drying by Boyde and Barger (1969) and Small and Marszalek (1969) does prevent surface tension but ice crystal formation and time required for pumping out the specimen to dryness has discouraged us. We believe an attractive alternative to freeze drying is the critical point method originated by Anderson (1951; for electron microscopy. He avoided surface tension effects during drying by first exchanging the specimen water with alcohol, amy L acetate and then with carbon dioxide. He then selected a specific temperature (36.5°C) and pressure (72 Atm.) at which carbon dioxide would pass from the liquid to the gaseous phase without the effect of surface tension This combination of temperature and, pressure is known as the "critical point" of the Liquid.

Rapid Switching

Electron microscopy is frequently used in preliminary diagnosis of plant virus diseases by surveying negatively stained preparations of crude extracts of leaf samples. A major limitation of this method is the time required to survey grids when the concentration of virus particles (VPs) is low. A rapid survey of grids for VPs is reported here; the method employs a low magnification, out-of-focus Search Mode similar to that used for low dose electron microscopy of radiation sensitive specimens. A higher magnification, in-focus Confirm Mode is used to photograph or confirm the detection of VPs. Setting up the Search Mode by obtaining an out-of-focus image of the specimen in diffraction (K. H. Downing and W. Chiu, private communications) and pre-aligning the image in Search Mode with the image in Confirm Mode facilitates rapid switching between Modes.

Cryostat Sections

Microwaves (MW) are electromagnetic waves which are commonly generated at a frequency of 2.45 GHz. When dipolar molecules such as water, the polar side chains of proteins and other molecules with an uneven distribution of electrical charge are exposed to such non-ionizing radiation, they oscillate through 180° at a rate of 2,450 million cycles/s. This rapid kinetic movement results in accelerated chemical reactions and produces instantaneous heat. MWs have recently been applied to a wide range of procedures for light microscopy. MWs generated by domestic ovens have been used as a primary method of tissue fixation, it has been applied to the various stages of tissue processing as well as to a wide variety of staining procedures. This use of MWs has not only resulted in drastic reductions in the time required for tissue fixation, processing and staining, but have also produced better cytologic images in cryostat sections, and more importantly, have resulted in better preservation of cellular antigens.

Abstract Functional capacity evaluations (FCEs) have become an important component of disability evaluation during the past 10 years to assess an individual's ability to perform the essential or specific functions of a job, both preplacement and during rehabilitation. Evaluating both job performance and physical ability is a complex assessment, and some practitioners are not yet certain that an FCE can achieve these goals. An FCE is useful only if it predicts job performance, and factors that should be assessed include overall performance; consistency of performance across similar areas of the FCE; consistency between observed behaviors during the FCE and limitations or abilities reported by the worker; objective changes (eg, blood pressure and pulse) that are appropriate relative to performance; external factors (illness, lack of sleep, or medication); and a coefficient of variation that can be measured and assessed. FCEs can identify specific movement patterns or weaknesses; measure improvement during rehabilitation; identify a specific limitation that is amenable to accommodation; and identify a worker who appears to be providing a submaximal effort. FCEs are less reliable at predicting injury risk; they cannot tell us much about endurance over a time period longer than the time required for the FCE; and the FCE may measure simple muscular functions when the job requires more complex ones.
