Actuarial Simulation 2

Read full description

The origin of this APP lies in the DAV/DGVFM student/teacher documentation. The aim of this series is to familiarise young people with the exciting subject of actuarial mathematics: Volume 1 - Stochastics of property damage The Actuarial Simulation2 Base APP enables Monte Carlo simulation in non-life insurance. The resulting overall loss distribution can be analysed by means of loss number and loss amount distribution. Graphics, moments and various quantiles are provided here. Poisson, binomial and negative binomial distributions are included as loss number distributions. The following loss level distributions can be simulated: Pareto, exponential, normal, generalised Pareto, gamma and Weibull distribution Attention: This APP is intended for private use only. Any liability is excluded.

The Eclipse App is a high-fidelity astronomical tool engineered for observers who demand absolute accuracy as well as beginners who need a guide through the exceptional experience of their first total solar eclipse. Powered by the latest 3D computational models developed by the Besselian Elements Team, this App provides accurate sub-second eclipse contact timings using lunar limb profile corrections. Whether you are a professional researcher, an astrophotographer, or a dedicated eclipse chaser, this app provides the rigorous data necessary for a successful expedition, from interactive map useful for planning, to simulating the countdown and exercise with the equipment, and for real time tracking in case you are moving in search of the right spot. Core Features: β€’ Precision Timing Engine: Real-time calculations of Contact Times based on your exact GPS coordinates β€’ Interactive Mapping: High-resolution path-of-totality overlays including umbral limits an the center-line. The IQP method accounts for the topography on both the lunar limb and at the observer site, as well as relying on an improved value for the eclipse solar radius (959.95" Β± 0.05", based on research by the Besselian Elements Team). The eclipse center-line and the northern and southern limits of the umbral shadow path also account for these three factors. Hence, these lines are not smooth lines, as in most publicly-available eclipse maps, but are noticeably jagged. Two lines are presented at each path limit corresponding to two values of the eclipse solar radius (959.90" and 960.00") in order to display a region of uncertainty rather than a single limit line. β€’ Live Audio Synchronization: A sophisticated voice-cue system that announces critical contact phases and astronomical phenomena (e.g., shadow bands, corona visibility, and solar filtration changes), allowing you to keep your eyes on the sky or your equipment. β€’ List of phenomena to observe during the eclipse at every step, so that you can be reminded to watch at the right time Designed for the Rigorous Observer: The Eclipse App eliminates the margin of error inherent in simplified models. Prepare for the next Great Eclipse with the most scientifically robust tool available on the App Store.
