Control of blood haemoglobin determinations by a simple effective method.
Thawed, frozen ;mixed oxalated' blood for haematology or citrated blood from the blood bank may be used as a precision control, maintaining reliability and accuracy, for periods of one to two years from a single batch of control material. Blood haemoglobin determinations using the cyanmethaemoglobin method and the Coleman Jr. spectrophotometer can be done routinely with a day-to-day variability...
متن کاملa Simple Speed Control Technique and Pulsating Torque Elimination Method in a Brushless Dc Motor
This paper presents a theoretical derivation and computer simulation of an optimal speed controller for a brushless dc motor using feedback from a linear model running in parallel with the inverter-fed model. The intent of the feedback from the linear model is to eliminate torque ripples from the inverter drive. A nonlinear model of such a motor, transformed into a linear model by a local diphe...

متن کاملHumidity Control in School Facilities
Consulting engineers who design school facilities are challenged with controlling space humidity while also providing continuous ventilation as required by ASHRAE Standard 62-1999, now part of most major building codes. What would appear to be a simple design process is complicated by various logistical and operational factors. Schools, by nature, have a high occupant density which results in l...
متن کاملA Simple and Effective Edge Detector
Nonlinear filtering based on a two concentric circular windows operator is introduced as a simple and effective way to find edges in image processing. The dual windows edge detector can operate with no fixed threshold, is isotropic, i.e. its response does not depend on edge orientation and has good noise immunity in the vicinity of edges. Computational requirements are limited and experimental ...
