Discrete Dynamical Systems and Difference Equations with Mathematica

Book Description

Following a work of Yorke and Li in 1975, the idea of discrete dynamical systems and difference equations developed quickly. The applying difference equations also increased quickly, particularly with the development of graphical-interface software that may plot trajectories, calculate Lyapunov exponents, plot bifurcation diagrams, and discover basins of attraction.

How illegal social structures help some but harm others

The has outraged millions, getting to light the gaps between your fortunate and fewer fortunate citizens. As being a social researcher who studies societal origins of monetary and health inequalities, it had been obvious in my experience it had become a symbol of deep structural inequalities within the U.S. social hierarchy. Such structural inequalities come in many forms, including wealth and health inequalities.

Demand Papers: Data Assimilation in Computational Mechanics – Recent Advances and New Trends

Using experimental data in colaboration with simulation models is becoming anactive research subject. Indeed, new experimental facilities (for example digital image/volume correlation (DIC/DVC)) now enable to gather a sizable and diversified quantity of data, which enables you to identify and validate complex models, in order to enhance predictions produced by simulations tools. In addition, data and models are increasingly more intertwined to enhance understanding in applications coping with structural health monitoring and control for example, with potential real-time dialogue between simulators and connected physical systems (e.g., the DDDAS concept). However, many challenges coping with data filtering, computational cost, or statistical sturdiness have to be addressed to be able to incorporate data efficiently.

Mobile Reachability. Guidelines by Alex Kirhenstein Medium

Guideline

When you’re holding your smartphones you’ve capability to operate just with a thumbs. Human thumbs can’t be extended to achieve middle to top screen areas because of physical limitations. So consumer experience ought to be based on this. Software developers should avoid placing any helpful buttons, input fields, features in top right or left corners (top area).

A bivariate prediction approach for adapting the health care system response to the spread of COVID-19

Abstract

The spread of COVID-19 implied a large and fast increase of demand for intensive care services. To face this increase in demand, health care systems need to adapt their response by increasing hospital beds, intensive care unit (ICU) capacity and by (re-)deploying doctors and other personnel. This paper proposes a forecast approach based on the Vector Error Correction model for the daily counts of hospitalized patients with symptoms and of patients in ICU, using publicly available data on the current COVID-19 outbreak in Italy, Switzerland and Spain. The level of analysis is the local government managing the health care system response, which corresponds to regions for Italy. The one-week-ahead forecasts are validated with out-of-sample data over successive weeks; they are found to provide timely and robust prediction of ICU capacity needs in Lombardy, the most-affected Italian region, starting from the sample of the first 2 weeks of data. The same methodology is successfully validated on other Italian regions, Switzerland and Spain. This approach may be used in other countries/regions/provinces to help adapt the health care system response to COVID-19 (or other similar disease); for this purpose, the open-source software code to produce the forecasts is provided with the paper.
