Calibration of Hewlett-Packard network analyzers: A precision viewpoint

Alternative calibration procedures are examined for Hewlett-Packard vector network analyzers which lead to an improved open-circuit capacitance model, and hence, higher measurement accuracy

Stabilized Zeeman split laser

The development of a stablized Zeeman split laser for use in a polarization profilometer is discussed. A Hewlett-Packard laser was modified to stabilize the Zeeman split beat frequency thereby increasing the phase measurement accuracy from the Hewlett-Packard 3 degrees to an accuracy of .01 degrees. The addition of a two layered inductive winding converts the laser to a current controlled oscillator whose frequency is linearly related to coil current. This linear relationship between coil current and laser frequency permits phase locking the laser frequency to a stable crystal controlled reference frequency. The stability of the system is examined and the equipment operation procedures are outlined

Rapid determination of selected meat components using near infrared reflectance spectroscopy

A new and rapid multicomponent analysis of foods has been developed by using near infrared reflectance spectrometry. The spectroscopic technique of Near Infrared Reflectance Analysis (NIRA) has required the use of transformation of the correlation matrix, a mathematical technique of multiple regression analysis in order to generate the empirical calibration required for the success of the technique. Preliminary calibration curves for beef, pork, and beef and pork mixture have been developed using an InfraAlyzer 400(\u27TM) (Technicon Industrial Systems, Tarrytown, N.Y.) and a Hewlett-Packard 9815\u27A\u27 calculator (Hewlett-Packard Company, Santa Clara, CA). The accuracy of these preliminary prediction regression equations was not satisfactory for the use of in-process control in meat processing. In subsequent experiments, a Vita Mix blender (Vita Mix Corp., Cleveland, Ohio) was introduced to improve the homogeneity of the samples and a Hewlett-Packard 85 personal computer (Hewlett-Packard Company, Santa Clara, CA) replaced the less powerful Hewlett-Packard 9815\u27A\u27. Nineteen beef samples with varying amounts of collagen were prepared and measured via the InfraAlyzer 400(\u27TM) and hydroxyproline. The multiple correlation coefficients (R(\u272)) of the prediction equations for hydroxyproline, protein, fat, and moisture were 0.9389, 0.7745, 0.9329, and 0.9425, respectively. Correlations of 0.2754, 0.5279, 0.8020, and 0.8745 were found between near infrared values and chemical analysis values for hydroxyproline, protein, fat, and moisture. The R(\u272) values for emulsified pork were 0.9469 for protein, 0.9662 for fat, and 0.9524 for moisture. Correlations between near infrared values and chemical analysis values were 0.8857 for protein, 0.9725 for fat, and 0.9628 for moisture. With the improved accuracy of prediction equations through the improved sampling procedure and the most capable computer programming, the near infrared reflectance analysis can be an alternative technique for rapid determination of selected meat components

Robust Simulation of a TaO Memristor Model

This work presents a continuous and differentiable approximation of a Tantalum oxide memristor model which is suited for robust numerical simulations in software. The original model was recently developed at Hewlett Packard labs on the basis of experiments carried out on a memristor manufactured in house. The Hewlett Packard model of the nano-scale device is accurate and may be taken as reference for a deep investigation of the capabilities of the memristor based on Tantalum oxide. However, the model contains discontinuous and piecewise differentiable functions respectively in state equation and Ohm's based law. Numerical integration of the differential algebraic equation set may be significantly facilitated under substitution of these functions with appropriate continuous and differentiable approximations. A detailed investigation of classes of possible continuous and differentiable kernels for the approximation of the discontinuous and piecewise differentiable functions in the original model led to the choice of near optimal candidates. The resulting continuous and differentiable DAE set captures accurately the dynamics of the original model, delivers well-behaved numerical solutions in software, and may be integrated into a commercially-available circuit simulator

Managing by Walking Around

{Excerpt} Management by walking around emphasizes the importance of interpersonal contact, open appreciation, and recognition. It is one of the most important ways to build civility and performance in the workplace. The hallmarks of the modern organization are satellite offices, remote offices, home offices, virtual offices, hotelling facilities, and the electronic mail that underpins—and promotes—these. Today, knowledge workers receive few telephone calls and electronic mail is their communication vehicle of choice. (The use of videoconferencing is growing,too.) After all, why should they walk around if they can type, point, and click? At the receiving end, managers are known to collect more than 150 messages each day. Yet, as knowledge workers on the rise tote up electronic status, they also distance themselves from colleagues. Managing by walking around was popularized by Tom Peters and Robert Waterman in the early 1980s because it was (already then) felt that managers were becoming isolated from their subordinates. At Hewlett-Packard, where the approach was practiced from 1973, executives were encouraged to know their people, understand their work, and make themselves more visible and accessible. Bill Hewlett and Dave Packard\u27s business philosophy, centered on deep respect for people and acknowledgment of their built-in desire to do a good job, had evolved into informal, decentralized management and relaxed, collegial communication styles. Theirs was the opposite of drive-by management
