COVID-19 Control: Can Germany Learn From China?

The coronavirus disease 2019 (COVID-19) outbreak started in China in December 2019 and has developed into a pandemic. Using mandatory large-scale public health interventions including a lockdown with locally varying intensity and duration, China has been successful in controlling the epidemic at an early stage. The epicentre of the pandemic has since shifted to Europe a...

Too Busy to Learn

The goal of this research is to analyze how individual learning interacts with an evolutionary algorithm in its search for best candidates for the Busy Beaver problem. To study this interaction two learning models, implemented as local search procedures, are proposed. Experimental results show that, in highly irregular and prone to premature convergence search spaces, local search methods are n...

تعیین و مقایسه میزان پایایی تأثیر درمانی دو روش Ultra Sound تحت استرچ و Hold-Relax بر کاهش کوتاهی عضله همسترینگ

    Background & Objective: The effect of simultaneous US(Ultra-Sound) with stretching, however, has not been compared with other manual stretching techniques like PNF(Proprioceptive Nueromuscular Facilitation). Furthermore, the permanency of the two techniques has not been investigated, either. Method: This study was a randomised clinical trial on 20 non-athlete and healthy women. The subjects...

Relax and Fix Heuristics for Simultaneous Lot Sizing and Sequencing the Permutation Flow Shops with Sequence-Dependent Setups

  This paper proposes two relax and fix heuristics for the simultaneous lot sizing and sequencing problem in permutation flow shops involving sequence-dependent setups and capacity constraints. To evaluate the effectiveness of mentioned heuristics, two lower bounds are developed and compared against the optimal solution. The results of heuristics are compared with the selected lower bound .
