Relationships Between Positioning Error Measures in Global Positioning System
Journal of Guidance, Control, and Dynamics, 1997Introduction I N Global Positioning System (GPS) positioning, various measures can be used to select satellites or to evaluate the positioning accuracy. Geometric dilution of precision (GDOP) and relative GDOP (RGDOP) are themost popularones.Though thesemeasures are used frequently, the relationship between them is not clear.

Temperature measuring position for electrical measurements
2009 International Students and Young Scientists Workshop "Photonics and Microsystems", 2009To investigate complex properties of material, measurements must be performed in wide range of temperatures. It is important especially in measurements of gas and humidity. The impedance spectroscopy measuring position allowing us to performing measurements in wide range of temperatures was made. Heating and cooling was performed by Peltier module unit.

An important – and very satisfying – task for the amateur solar observer is recording the Sun’s appearance each day and measuring the positions of sunspots and other features. The cheapest and most convenient way of doing this is to make a drawing of the Sun.

Measuring Responsibilities in Nursing Positions
The American Journal of Nursing, 1961gical nurses, delivery room nurses? Those in the emergency room? These were some of the questions we asked ourselves about a year ago when we were faced with some perplexing problems of nurse turnover and staffing. Like most hospitals, we were paying staff nurses the same basic salary range regardless of assignment, on the assumption that the jobs were

Quantum Measurement with a Positive Operator-Valued Measure
Acta Physica Hungarica B) Quantum Electronics, 2003In the quantum theory of measurement, the positive operator-valued measure (POVM) is an important concept, and its implementation can be useful. Following a brief review of the mathematics of POVMs in quantum theory, a particular implementation of a POVM for use in the measurement of nonorthogonal photon polarization states is reviewed.

Measuring Legislators' Policy Positions
American Politics Quarterly, 1979Numerous scholars have used roll-call votes to analyze legislative behavior and the impact of party and constituency on legislative behavior. It is argued in this article that roll-call votes provide an insufficient data base on which to determine the overall impact of party and constituency because they do not indicate a legislator's degree of ...

Position measurements with radiosondes
IEEE Journal of Oceanic Engineering, 1989The use of Omega sondes, designed for the determination of upper air wind vectors, for relative position measurements on the ground is described. The technique shows promise in measuring the deformation of sea ice, the motion of oceanic surface water, and the trajectories of constant-level balloons.
