This paper introduces an assertion scheme based on the brpwprd errw amlysis for error detection in algorithms that solve dense systems of linear equations, A z = b. Unlike previous methods, this Backward Error Assertion Model is specifically designed to operate in an environment of floating point arithmetic subject to round-off errors, and it can be easily instrumented in a Watchdog processor e...

An attractive alternative to least-squares data determined by using the median rather than the modeling techniques is the use of absolute value arithmetic mean. Algorithms for absolute error error criteria. Unlike the least-squares techniques minimization are often approximately as costly the inclusion of some infinite blunders along with as least-squares algorithms; however, unlike the data wi...

In this paper a practical method for tropospheric effects on GPS derived coordinates in absolute mode is presented. GPS observations at the permanent GPS stations can be used as source of information for the modeling. The developed model is a time-dependent model and as such differs from usual tropospheric models, which are based on atmospheric parameters, i.e. temperature, pressure and humidit...
