Ecological and sustainable modes of transport should be the main modes of transport of goods. Promotion of railway freight transport is a key element of the EU policy. It is important to have an ...appropriate transport infrastructure to ensure sustainable competitive railway transport. It is able to ensure the most flexible mobility of the goods with the most advantageous parameters. This article analyses the current status as well the level of achievement of the objectives set by the European Commission. The article also deals with the established nine corridors for international railway freight transport. The aim is to introduce different measures that should help increase the efficiency and competitiveness of railway freight transport in the European countries under CIM transportation mode. When designing new corridors, it is necessary to analyse and optimize the current railway network. Optimization solutions are used to analyse the network analysis methods. In particular, the critical path method (CPM) and the critical chain method (CCM) are used.
Moisture and its negative effects on monuments are a widespread problem that needs to be tackled especially to save historical buildings. The moistening of objects, whether historical or new, is not ...only part of our climate zone, but can be attributed to a global character, as evidenced by a number of publications and research on the issue of water logging of buildings that date back to 1892. It is not only a threat to the preservation but also the functionality of historical structures, because it is responsible for reducing the mechanical performance of the masonry, as the presence of water in the pores of the building material negatively affects the tensile strength and also the compressive strength. It also causes degradation of these materials, which can be constantly exposed to cyclic freezing and subsequent thawing, biodegradation and migration and subsequent crystallization of salts. Moisture also contributes to increasing the thermal conductivity of these constructions, resulting in high energy consumption for heating. Last but not least, we can associate various respiratory diseases of people living in this environment with moisture. Due to the serious effects associated with rising damp in the masonry, water capillarity is rightly considered a key factor in the protection of heritage. The origin of moisture can be attributed to several facts, but in the present research we focused mainly on rising damp and its negative impact on historical structures. The paper will summarize the results obtained so far and conclusions from various authors investigating the technology of additional impermeable layers. Subsequently, we will analyze and describe the obtained measurement results before and after the use of undercutting technology on two specific historical buildings in Slovakia. All the research and measurements were carried out in situ, which helped us to achieve objective results, the outcome of which is this work. The measured values show a significant drying of the structure above the plane cut and a positive effect on the repaired structure. The research also encourages further investigation of moisture acting mainly below the level of new insulation and its impact on masonry.
The article is focused on analysis and rating of the quality in the passenger railway transport logistics. At first is described the relationships between logistics and transport, logistical demands ...for transport and functions of logistics in rail transport. In the third chapter is explained quality assessment including the description of the quality indicators in passenger rail transport and making a proposal of the new methodology for this rating. Consequently this methodology is tested for chosen transport route and is concerned with monitoring quality of the transport routes in the railway network.
The moisture affects all materials on the earth surface, but we have developed a specific sensitivity toward moistening of architectural heritage buildings. Water in construction materials and on ...their surface influences partially their technical state like their stability, but usually not that much as people can think. Unwanted moisture is usually dangerous at very soft construction materials, like clay bricks. But especially the water soluble salts, the water transports through the masonry, can act as a very dangerous destructive material, influencing destructively especially surface plasters. And in the case of historical wall paintings are the losses on cultural heritage invaluable. To deal with moisture effectively we can use some specific technologies, but the most effective ones have a specific destructive influence on the historical construction material. And this is the point of conflict between technical and methodical points of view. So the basic scientific questions in this field can be such ones: are the destructive technologies for fighting moisture in historic masonry really effective? And are they to be accepted also methodically?
This article deals with the problem of application of different forms of transport which create by the force of mutual connection the transport in its "door to door" quality. The aim of the transport ...system is to decrease the level of individual motor transport on sustainable level which is nowadays for many modern states an absolutely necessity.. Such integrated transport system must also take into account the Pedestrian transport, the Cycling transport, the Car sharing and the Car pooling together with adequate infrastructural, organizational and information background which will contribute to the optimal utilization of complex transport systems.
The analysis of technological procedures in transport and logistics aimed at innovating established procedures is an ongoing process not only in the present. Constant innovation can significantly ...reduce the operating costs and dramatically increase transport speeds. Continuous modernization reflecting customer needs keeps the rail sector competitive with other modes of transport. The research explores the use of augmented reality in procedures for processing sets of wagons in freight trains. The analysis involves technological procedures in rail freight transport at the marshalling yard, revealing characteristics of augmented reality. We assessed the feasibility of implementing options separately for the carrier, the railway infrastructure manager and the combination of both. The implementation of augmented reality is always rational, representing a simplification, acceleration or reduction of costs in the usual technological procedures. Incorrectly implemented augmented reality may cause serious complications to the technological process, including undue delays, overpricing and safety threats to employees operating in the track.
Planning the extent of transport services within a selected territory is a topical issue especially in the context of developing integrated transport systems. The objective of this research study is ...to design a sustainable system of public passenger transport that would be an alternative to expanding individual transport. The implementation of a quality and efficient transport service is a relatively complex process, since, currently, there are no generally applicable principles for its design. This manuscript presents general results of research aimed at solving the problem of transport service within a selected territory issue with a focus on rail transport as an efficient transport system representing a backbone of a transport system. The subject of the investigation is to compile a set of factors affecting the design of the transport concept. The output of the manuscript consists in a proposal of a generally applicable procedure including a calculation of transport potential and characteristics of the inputs. Subsequently, based on the resulting values, it will be possible to determine the extent of the transport services provided by rail transport in any territory, which will contribute to a more efficient and high quality theoretical graph of train running.
