In freight transportation the planning methods and decision support systems are a crucial point to be considered, yielding interesting research opportunities for the development of optimization.The aim of our project was to research, develop and implement an artificial intelligence (AI) assistant module bringing new AI-based capabilities of optimization and simulation for enterprise-wide operational activities such as management of railway resources and constraints in an efficient and userfriendly manner.The main objective of the current paper concerned the best way to transport freight from given origins to given destinations within time constraints using the railway service provided by the network.This planning problem is faced in four steps (preprocessing, constraints definition, optimization phase and model's testing).The objective function considers the train operation costs, consumption and time duration.Machine learning algorithms are developed to optimize the objective function according to an enormous number of decision variables and complicated constraints.The platform is tested in a real-world Romania railway network.Future progress of the project will provide models' testing results and continuous improvement of the algorithms performance.

New aspects concerning the photodegradation (PD) of ampicillin are reported by photoluminescence (PL), Raman scattering and FTIR spectroscopy. The exposure of ampicillin in the absence (AM) and in the presence of the excipient (AMP) to UV light leads to an intensity diminution of the photoluminescence excitation (PLE) and photoluminescence (PL) spectra and the emergence of a new IR band at 3450 cm−1. The photoluminescence studies demonstrate that the AM PD is amplified in the presence of excipients and an alkaline medium. In this last case, the PD process of AM involves the emergence of new compounds, whose presence is highlighted by: (i) the emergence of the isosbestic point at 300 nm in the UV-VIS spectra; (ii) a change in the ratio between the absorbance of IR bands situated in the spectral ranges 1200–1660 and 3250–3450 cm−1; and (iii) a change in the ratio between the intensities of the Raman lines localized in the spectral ranges 1050–1800 and 2750–3100 cm−1. A chemical mechanism of the PD processes of AM in an alkaline medium is proposed.

The article relates to the realization of a new concept of malleable in the electromagnetic field thermoplastic composite materials. The object of the article is to provide the description of new types of composite materials which can be heated in an electromagnetic field and brought to an optimum temperature for mechanical processing by plastic deformation, as well as to perform some tests and analyze the influence of some material components on dielectric properties of malleable composite materials.

Electromagnetic compatibility issues and the generated because of this interference are a major concern on electrical and electronic products, mainly in the domains of communications, information technology, transportation, safety and medical services. This paper presents the obtaining process of nano-structured paints and primers with electromagnetic shielding properties, designed for automotive components sector.

The study of correlation between concentration and particles size in order to optimize the thermal heating process by exposure of composite materials to microwave radiation is a very important phenomenon if we want to develop materials that can be used in innovative bonding processes.

In the contemporary organisations the human resources and the facilities that have are two majors driven forces for performance. In my own PhD research, conducted between 2007 and 2012, I was demonstrated that there are strong relations between the facilities and business performance. In 2018 I started a new research, more focused on the impact of new ways of working on the organisational performance and the relation between them and wellbeing. The main part of the current project is a case study from the Romanian branch of an Austrian Insurance Company where we investigate the possibility to reduce the office space for 340 people keeping the same activities and number of employees but introducing new ways of working. Another research part called “Office Flexibility” has the purpose to evaluate the level of performance and wellbeing of people from Romanian companies that already have introduced new ways of working as flex / home office and coworking plus the general awareness for this topic. Office Flexibility research is based on an electronic questionnaire that was applied to a number of 94 office workers. Both elements of the research show that Romanian office workers know well concepts of the New Ways of Working and they consider that are suitable solutions to improve the level of personal wellbeing and the level of organizational performance.
