The practical application to the quantum systems covered the Klein-Gordon equation; Sine-Gordon equation; Klein-Gordon-Schrodinger equation (KGS); Gross-Pitaevaskii equation (Bose-Einstein Condensates, BEC); Klein-Gordon-Maxwell equation, and so forth. For the particles physics, single particle, couple heavy particles, many body particles problems had been considered in the quantum theory and computational approach. Three parts contained in the book, Part I is Quantum Control of KGS System; Part II is Quantum Control of BEC; Part III is Control of Quantum System. It is certainly hope to connect system control field to chemistry, physics as well as other research areas (aero space, surface science, etc.). Thereby, wish to get much more interest worldwide on the hot topic quantum system control. ------------------------------------------------------- From: WIM2021 Organization Committee [log in to unmask] Date: July 27, 2021 Subject: Industrial Mathematics, Italy, Oct 2021 We are pleased to announce this Call for Abstracts for the 2nd Workshop in Industrial Mathematics - WIM2021 - to be held in Catania, Italy from October 20-22, 2021.

The position is in collaboration with Horizontal Sofware (https://www.horizontalsoftware.com/). Horizontal Software (HSW), created in 2010, is a publisher of SaaS and App solutions, specialized in management and optimized planning of human resources. The E-OPTIM solution provided by HSW is intended for the planning and optimization of human resources, taking into account heterogeneous constraints: legal, organizational and social. A company's performance is closely linked to well-being at work. It is therefore very important to take into account employee preferences in the development of schedules. The goal of the PhD thesis is to develop heuristic algorithms that take into account employee preferences in addition to the standard constraints (legal, organizational and social). This additional requirement poses a severe challenge as it complicates a problem that is already difficult to solve. To overcome this challenge the candidate will use the most advanced techniques in the field of mathematical optimization and artificial intelligence. Required competences: Good experience with mathematical optimization; Knowledge in machine learning and deep learning is considered as a plus; Excellent programming skills. To apply or to have more information, please contact Roberto Wolfler Calvo ([log in to unmask]) and Nora Touati ([log in to unmask]). ------------------------------------------------------- From: Badih Ghusayni [log in to unmask] Date: August 01, 2021 Subject: Contents, Intl J Mathematics and Computer Science, 16 (4) The papers below can be downloaded freely via http://ijmcs.future-in-tech.net/Volume16.4.htm: Thejasvi Nagaraju, Shubamangala B.R., Elicitation of Resilient Requirements through Countermeasure Decomposition Technique.
