This proceedings volume gathers selected, peer-reviewed papers presented at the 2nd International Conference on Mathematics and its Applications in Science and Engineering – ICMASE 2021, which was virtually held on July 1-2, 2021 by the University of Salamanca, Spain. Works included in this book cover applications of mathematics both in engineering research and in real-world problems, touching topics such as difference equations, number theory, optimization, and more. The list of applications includes the modeling of mechanical structures, the shape of machines, and the growth of a population, expanding to fields like information security and cryptography. Advances in teaching and learning mathematics in the context of engineering courses are also covered.This volume can be of special interest to researchers in applied mathematics and engineering fields, as well as practitioners seeking studies that address real-life problems in engineering.

This proceedings volume convenes selected, peer-reviewed papers presented at the 3rd International Conference on Mathematics and its Applications in Science and Engineering - ICMASE 2022, which was held on July 4-7, 2022 by the Technical University of Civil Engineering of Bucharest, Romania. Works in this volume cover new developments in applications of mathematics in science and engineering, with emphasis on mathematical and computational modeling of real-world problems. Topics range from the use of differential equations to model mechanical structures to the employ of number theory in the development of information security and cryptography. Educational issues specific to the acquisition of mathematical competencies by engineering and science students at all university levels are also touched on. Researchers and university students are the natural audiences for this book, which can be equally appealing to practitioners seeking up-to-date techniques in mathematical applications to different contexts and disciplines.

Die gegenw rtige weltweite wirtschaftliche Situation wird ihren Platz in Geschichtsb chern als Finanz- und Wirtschaftskrise" wiederfinden. Mit dem technologischen Fortschritt und der Globalisierung hat auch die Vernetzung und Korrelation zwischen Unternehmen weltweit zugenommen. sterreich ist nat rlich nicht unversehrt geblieben. Explodierende Arbeitslosenquoten, Insolvenzanmeldungen, Betriebsschlie ungen und Liquidit tsprobleme von Unternehmen sind nur einige Auswirkungen der Wirtschaftskrise. Der sterreichische Gesetzgeber wollte durch Ma nahmen die Bev lkerung und die Wirtschaftsbeteiligten unterst tzen, um die Auswirkungen der Krise abzuschw chen. Hierf r kam die Steuerreform 2009 ins Gespr ch und das Steuerreformgesetz 2009 wurde am 31. M rz 2009 kundgemacht. Auch das Konjunkturbelebungsgesetz 2009, welches am 18. Juni 2009 in Kraft getreten ist, sollte seinen diesbez glichen Beitrag leisten. Diese Arbeit analysiert die Auswirkungen der Steuerreform 2009 auf Investitionsentscheidungen von Unternehmen anhand von aussagekr ftigen Beispielen und unterst tzt die Ergebnisse durch Meinungen der Experten.
