Stereoselectivity in asymmetric processes and molecular assemblies
(Universita degli studi di Salerno, 2020-02-19)The aim of this thesis was to explore different areas of organic chemistry in which the stereocontrol in the design of chemical processes and/or molecular assemblies is necessary. Therefore, the stereoselectivity in ... -
Polyhedral analysis and branch and cut algorithms for some NP-hard spanning subgraph problems
(Universita degli studi di Salerno, 2020-01-07)There is a widespread need to use a quantitative approach for the solution of decision problems that arise in many different areas of real life. The goal is to choose which decisions to take to manage a real system as ... -
A game theoretical approach to safe decision making system development for autonomous machines
(Universita degli studi di Salerno, 2021-03-20)One of the major technological and scientific challenges in developing autonomous machines and robots is to ensure their ethical and safe behavior towards human beings. When dealing with autonomous machines the human ... -
Comparative studies on the physiological adaption of mitochondria and endoplasmic reticulum to envirnmental xenobiotics from invertebrate to mammals
(Universita degli studi di Salerno, 2021-04-20)Mitochondria are critical for numerous cellular and biochemical processes. The reciprocal interaction between mitochondria and the endoplasmic reticulum impacts several cellular functions. In cellular and animal models, ... -
