Abstract: The increase of atmospheric greenhouse gases results in climate changes which cause the rise of sea level and an increased frequency of extreme climatic events including intense storms, heavy rainfall and droughts. There is a lower consensus on the magnitude of changes in climate variables, but several studies show that climate change has an impact on the availability and demand for water resources. Major rivers worldwide have experienced dramatic changes in flow, reducing their natural ability to adjust to and absorb disturbances. Given expected changes in global climate and water needs, this may create serious problems, including loss of native biodiversity and risks to ecosystems and humans from increased flooding or water shortages. This document analyzes the potential impact of climate change on water resources in Romania, Mehedinți County. The work ends with quantitative assessments of the effects of climate change on hydrology for a part of the Mehedinți County basins.

Abstract: New stringent emission limits require the drastic reduction (80 to 95%) of harmful emissions of NOx and PM. Due to the special characteristics of vessels (long engine lifetime, small series, greater variety of technical configurations) also retrofit after-treatment solutions, or solutions where new engines and after-treatment systems are purchased separately are necessary. For these options economical and effective certification procedures are needed.

Abstract: The aim of the paper is to present some aspects about how we can use multiple attribute decision making tools for modeling global air pollution level, an indicator which can be used to analyze and compare the air quality from different regions in order to establish their hierarchy according to this aspect. An indicator for the global air pollution level, obtained by applying SAW method is proposed in this paper. When applying multiple attribute decision making methods not only different methods can be used to solve the problem of interest, but different kind of tools within same method. In this paper we also make comparisons between different normalization techniques we can use, in order to see if and how they influence the proposed indicator and, therefore, the final hierarchy of the regions we want to rank according to it.

Abstract: Any perturbation in politics and in economics affects the logistics of freight, from local to regional, national and even international. It creates weaving of the total volume of cargo and subsequently weaving of the market’s necessities regarding the transportation and warehousing. More, weaving of the volume of investments is specific effect. Such mechanism has been recorded in the last 7 years: increasing 2012-2015, decreasing 2015-2017, increasing 2017-2018. From 2017 it has been recorded a higher value of individual transactions, compared to 2016, when the transactions have dropped dramatically. In the end of the 2017, the mass center of the warehousing facilities were in the triangle Bucuresti-Pitesti-Ploiesti. The structure of the warehousing offer was at 31.12.2017: Green, energy efficient warehouses with available space for rent - Warehouse spaces: 197.440 m², Warehouse rent: 45.540 m², Average rental price: 2.73 €; A category warehouses with available warehouse space for rent - Warehouse spaces: 5.832.841 m², Warehouse rent: 2.312.824 m², Average rental price: 12.79 €; B category warehouses with available warehouse space for rent - Warehouse spaces: 487.388 m², Warehouse rent: 222.248 m² , Average rental price: 2.98 €; C category warehouses with available warehouse space for rent - Warehouse spaces: 109.432 m², Warehouse rent: 60.582 m² , Average rental price: 2.13 €; D category warehouses with available warehouse space for rent - Warehouse spaces: 1.950 m², Warehouse rent: 1.950 m² , Average rental price: 3.75 €; the rest to 100% was shared among Cold, Break-Bulk, Cross dock, Transload, Hazmat, and Food grade warehouse types.

Abstract: This paper presents some ideas of how it would be possible to enable the integration of inland waterway transport in the intermodal supply chain. Taking into account that the intermodal transport may be interpreted as a chain of actors who supply a transport service, inland navigation can play a crucial role in increasing supply chain service performance. In order to overcome the obstacles related to the inter-connection of the river freight transport with other ways of transport it is necessary to reorganise the entire European market of the IWT corridors.

Abstract: There are several innovations to be found in the inland waterway sector. European Federation of Inland Ports EFIP defines trends in Inland Ports and Current EU Policy Developments in 2014. The trends include urban logistics, biomass transports, as well as the transportation of heavy cargo. The Transport White Paper of 2011 targeted for freight transport to shift from road to rail and IWW by more than 50% by 2050. The described technological and organizational as well as logistic trends are linked and evaluated regarding their impact onto model variables of the different transport models and tools employed. Technological advancements have an impact on organizational and logistics issues and cannot be discussed independently from these topics. The analysis is performed for each trend individually and does not take into account the different maturities and interdependencies among the different trends evaluated.

Abstract: This work presents some relevant data of the last period for the transport and logistics market from Romania. The Romanian transportation and logistics market is currently estimated at the value of over 30 billion lei (approximately 6.7 billion euros), with the biggest 20 players having a market share of almost 20%. The most concentrated area for the storage of the transported goods is in Bucharest, the capital city and around some cities like Timisoara, Cluj, Ploiesti, Brasov and Pitesti. There are also other cities like Oradea, Sibiu and Arad, that are on full expanding process.

Abstract: This work presents some logistics and transportation challenges that were solved by 3 different student groups from 3 different European entities. These groups were: the STC Group, from The Netherlands, made of 12 students; the FHOO Group, from Austria, which comprised a number of 10 students and the IMST Group from Romania, made of 12 students. Each of the group had a specific task of finding the best logistic and transportation solution for each of their task. Also, they need to take into account several important parameters like air pollution problem, the shortest way of reaching to destination, the way of transport and others, which were decisive in choosing the right solution.

Abstract: Nowadays, there are threats everywhere around us, on land, in the air and at sea. The most important and dangerous ones at the same time are the threats with impact on security and safety. At sea, more than in other fields, these threats are very different, starting with piracy, armed robbery and taking hostages up to different forms of terrorist or cybercrime acts. Piracy and other violent activities appear specifically in particular geographical areas, mostly based on different conflicts inside seaside countries. For the other threats considered, such as different types of terrorist activities, there are not geographical areas of interest defined. They can appear all over the world. The terrorist acts in the maritime field are not necessarily to be treated as a direct action, background systems may also be used, like information or operative computer control systems, which have a great importance and impact on the proper functionality of the maritime systems. Nowadays, there are some serious cybersecurity incidents with major impact on a worldwide scale. In the last decade there was a limited approach to address such major issues, most of them based on several methods, which had a centralized point of failure: the lack of knowledge and adaptability versus new ways of system penetration. For the technical vulnerabilities there are different solutions already developed, or being developed, for data protection and information security. Despite some important developments on data security, many of the important sectors remain under high risk regarding cybersecurity. The maritime sector today is considered one of the most exposed sectors to cyber threats, due to the global nature of the business as well as a great economical, geopolitical and environmental influence. Here, the higher vulnerability remains the human element, as an operative part of the data systems. Humans will always be a source for mistakes and errors. “To err is human” can be successfully applied in many activity fields, included the maritime one. The main purpose of any study on these matters, human factor and cyber protection is to start from the unpredictability of the human behaviour. It would be almost impossible to provide a totally secure information system, as long as such a system is exposed to the human factor. This paper intends to analyse possible models of human behaviour with impact on data systems’ protection in the maritime field and how systems can be improved and highly secured for any vulnerabilities based on these models.
