Estimate Hitting Time by Hitting Probability for Elitist Evolutionary Algorithms
Drift analysis is a powerful tool for analyzing the time complexity of evolutionary algorithms. However, it requires manual construction of drift functions to bound hitting time for each specific algorithm and problem. To address this limitation, general linear drift functions were introduced for elitist evolutionary algorithms. But calculating linear bound coefficients effectively remains a problem. This paper proposes a new method called drift analysis of hitting probability to compute these …

Operational Control of a Multi-energy District Heating System: Comparison of Model-Predictive Control and Rule-Based Control
This study focuses on operational control strategies for a multi-energy District Heating Network (DHN). Two control strategies are investigated and compared: (i) a reactive rule-based control (RBC) and (ii) a model predictive control (MPC). For the purpose of the study a small scale district heating network is modelled using Modelica. The production plant combines a heat pump, a gas boiler and a thermal solar field on the production side with a storage tank for flexibility purposes. On the cons…

Die Stadt #Tuttlingen verfolgt mehrere #Windkraft-Projekte, darunter auf dem Hattinger Berg mit bis zu vier Anlagen.

Tuttlingen verfolgt Windkraft-Pläne an mehreren Standorten
Auf dem Hattinger Berg bei Tuttlingen könnten Windräder gebaut werden. Doch das ist nicht die einzige Stelle, die für einen Windpark geeignet sein könnte.

Ich möchte Euch meinen Gartenspagat vorstellen. Ich habe die Rolle vor 10 Jahren bei der BayWa für 16 Euro peng gekauft und benutze sie im Garten für alles. Heute ist sie noch etwa halb voll, also noch rund 600 Meter. Im Handel kostet die Rolle heute 30 Euro, wenn ich meine halbe also jetzt verkaufe, bekomme ich 15 von 16 Euro wieder. 😋
