the dedicated satellite mission goce will sense various small mass variations along its path around the earth. here we study the effect of the earth’s topography and atmosphere on goce data. the effects depend on the magnitude of topographic height, and they will therefore vary by region. as the effect of the atmosphere and topography must be removed from the total gravity anomaly prior to geoi...

For the area of the United States the Shuttle Radar Topography Mission (SRTM) height models are available with 1 arcsec spacing instead of the 3 arcsec spacing outside the country. Only special users are getting the 1 arcsec height information outside the USA. 1 arcsec and also 3 arcsec SRTM height models have been investigated in a mountainous area, covered nearly completely by forest, in an u...

Introduction: Gridview is a software application designed to aid researchers in their efforts to analyze, measure and visualize gridded data products such a planetary topography. While it was specifically designed to be used with Mars Orbiter Laser Altimeter (MOLA) data, it also functions well as to tool for analyzing other gridded data sets. It has been used by researchers and students to stud...

Introduction: Gridview (figure 1) is an IDL software application designed to aid researchers in their efforts to analyze, measure and visualize gridded data products such a planetary topography. While it was specifically designed to be used with Mars Orbiter Laser Altimeter (MOLA) data, it also functions well as a tool for analyzing other gridded data sets. It has been used by researchers and s...

Cracking of laser hybrid welding of eccentric fillet joints has been studied for stainless steel. Laser hybrid welding enables narrow deep welds with freedom for shaping the upper weld geometry. The significance of geometrical aspects like weld toe radius, weld surface topography and lack of fusion on fatigue cracking is discussed. Constant amplitude four point bending tests, S/N-curve, topogra...

An experimental observation related to the influence of the bottom topography on the development of gravity driven surface boundary currents in rotating systems is described and discussed. The results presented concern the local flow geometry in the vicinity of the head of the current. It is observed that, depending on the values of the independent experimental variables and the inclination ang...

purpose: to evaluate the effect of location and size of chalazia on refractive error, corneal topography and visual acuity. methods: this randomized non-controlled clinical trial was conducted on patients with chalazion aged more than 3 years with minimum duration of one month. all patients underwent chalazion excision by the internal or external approach. results: two-hundred and fifty-three e...

Abstract Instrumented indentation test (IIT) is a depth-sensing hardness allowing nano- to macro-mechanical characterisation of surface mechanical properties. Indenter tip geometry calibration allows nano-scale characterisation, overcoming the limits conventional tests. Calibration critical ensure IIT traceability and applicability for quality verification in manufacturing processes. The accura...
