Manual for the determination of Effect size indices and Practical Significance
Sep 05, 2017 - Manual for the determination of Effect size indices and Practical Significance H. S. Steyn (jr) Preface In my work as a statistical consultant over the last twenty years I have found that there is a dire need to be able to make assertions concerning practical significance, particularly in Human sciences. This requirement exists for…https://natural-sciences.nwu.ac.za/scs/manuals/roc-analysis
Manual for ROC analyses
Mar 06, 2017 - Manual for ROC analyses Preface This guide, which leans heavily on the book of Krzanowski & Hand (2009), was written in an attempt to make it easier for the researcher to understand the theory behind and methods of ROC analyses. It is further attempted to explain the calculation methods by way of examples. With these calculations it is…https://natural-sciences.nwu.ac.za/scs/manuals/roc-analysis/manual

Gamma-ray Astronomy / High-energy Astrophysics
Jan 16, 2024 - The High Energy Stereoscopic System (H.E.S.S.) near Windhoek, Namibia, is the world's leading gamma-ray observatory. It detects gamma-rays that carry more than a billion times the energy of visible light, and thereby probes the most violent places of the Universe, including black holes, neutron stars, and supernova remnants. This array of five…https://natural-sciences.nwu.ac.za/space-research/star-formation-and-radio-astronomy
Star-Formation and Radio-Astronomy
Jan 04, 2017 - Star formation can be considered as one of the most basic processes in the Universe. It is hard to imagine a Universe without stars. Perhaps the most amazing aspect of the star formation process is that it takes matter which is at a very low density, of the order of hundred thousand molecules per cubic centimetre and which is very cold, about -…https://natural-sciences.nwu.ac.za/space-research/physics-in-application

Jan 04, 2017 - Innovative Astro Tegnologies: Low Noise Amplifiers A novel Low Noise Amplifier (LNA) technique for radio telescopes (such as the planned SKA), that has lower noise over much broader bandwidths and at higher temperatures than standard LNA's, was developed. Due to the broad bandwidth, this technique makes it possible to…https://natural-sciences.nwu.ac.za/space-research/contact-us
