Some Experiences with Evaluation of the Load Carrying Capacity of Bridges Using in Situ Load Tests
Authors: Schmidt Jacob Wittrup , Henriksen Arne , Engelund Svend
Published: February 2021

The evaluation of the load carrying capacity of bridges is usually performed using a computational model and a number of codes that specify the relevant ma terial properties and loads. This approach ensures that the evaluation of the load carrying capacity is performed such that the bridge has an acceptable level of safety
with respect to a number of adverse events such as collapse (ultimate limit state) and large deformations
(serviceability limit state). However, experience indicate that redistribution of load effects, interaction
between structural elements, the actual boundary conditions and other factors may provide a higher load
carrying capacity than the one determined on the basis of the computational model. The Danish Road
Directorate has in cooperation with The Danish Technical University and COWI A/S performed a number of
in situ load tests of concrete bridges in order to determine the actual load carrying capacity of the short span
concrete bridges (up to 12m). The paper presents the planning and the execution of the tests. Further, it is
demonstrated how the results may be used in order to determine the actual load carrying capacity of a
bridge.
Performance Based Practical Design
Authors: Daetz Leif Ole , Robineau Jonas , Norskov Stine
Published: February 2021

This paper presents the application of ‘Performance Based Practical Design’ (PBPD) methods to Danish infrastructure projects. PBPD is a decision-making process developed by the US Federal Highway Administration (FHWA) and this paper adapts the process to the standards and regulations of Denmark, resulting in the development of a comparative tool for selecting project options. The tool was tested on the E45 highway in Jutland, which is to be widened from four to six lanes. Civil structures along the highway are identified and the constraints they offer to the road layout are determined and implemented in the tool. A rating for each cross-section is determined, enabling users to compare several cross-sections with regards to a project specific baseline and site-specific constraints and ensure a robust qualitative and quantitative process.
Parametric Studies of Bridge Specific Assessment Live Loads and Implications for Assessment
Authors: Benham N. , Mundell C. , Hendy C. R.
Published: February 2021

A number of UK long span suspension bridges now require routine inspection, assessment and maintenance to ensure their continued durability. The UK Design Manual for Roads and Bridges (DMRB) has explicit guidance on the traffic loading for assessment lengths up to 50m, however beyond this the assumptions become conservative. In these instances, the assessment of these structures requires a Bridge Specific Assessment Live Load (BSALL) to be derived. Although a number of methodologies exist to derive BSALLs, there are several parameters that may significantly affect their results and there is little published guidance on the subject.

Through recent work covering the calculation of suspension bridges, Atkins have completed many parametric studies, considering different distribution methods and the relative importance of the various parameters involved. This paper discusses the above themes and outlines the advancements made by Atkins in this field, highlighting the critical parameters to consider, the advantages and limitations of the various approaches, and a recommended approach based on our findings to date.
Probability Based Assessment of a Motorway Bridge in Denmark
Authors: O'Connor Alan , Pedersen Claus , Roldsgaard Joan Hee
Published: February 2021

The paper presents the practical application of the Danish Road Directorate guideline for probabilistic assessment of bridges to an actual bridge structure, which failed to demonstrate sufficient load carrying capacity following deterministic assessment. The bridge, a post-tensioned box girder structure, was built in 1965. In addition to presentation of the safety classification of the structure the results of importance and sensitivity studies are presented which indicate the controlling variables. Following the assessment, bridge specific partial safety factors are calibrated for the critical limit state at the β-point which are compared with the global partial factors prescribed for deterministic assessment. It is important to point out that at no stage does the guideline compromise the safety of the structures presented, rather it provides a mechanism for determining their structure-specific safety for comparison with that deemed legally acceptable.

mparison of model-based identification methods for reserve-capacity assessment of existing bridges
Authors: Proverbio Marco , Favre François-Xavier , Smith Ian F. C.
Published: February 2021

The goal of model-based structural identification is to find suitable values of parameters that affect
structure behaviour. To this end, measurements are often compared with predictions of finiteelement
models. Although residual minimization (RM) is a prominent methodology for structural
identification, it provides wrong parameter identification when flawed model classes are adopted.
Error-domain model falsification (EDMF) is an alternative methodology that helps identify candidate
models – models that are compatible with behaviour measurements – among an initial model
population. This study focuses on the comparison between RM and EDMF for the structural
identification of a steel bridge in Exeter (UK). Advantages and limitations of both methodologies are
discussed with reference to parameter identification and prognosis tasks such as quantification of
reserve capacity. Results show that the employment of RM may lead to wrong identification and
unsafe estimations of reserve capacity.
How to assess historic iron and steel bridges
Authors: Helmerich Rosemarie
Published: February 2021

The early industrialization process required a higher and higher developed infrastructure to transfer more
and more people and goods. These requirements lead to the development of new materials that can resist
the higher loading, to advances in mechanical engineering, more sophisticated calculation methods and
transfer of all these advances to infrastructure to build longer spanning or higher rising structures. During
the 18th and 19th century, the advances in industrialization resulted in new production processes, for iron,
too. After using iron in mechanical engineering, it was applied to infrastructure as well [1]. Today, these first
old iron and early mild steel structures belong to the cultural and technical heritage of the world. When
looking at them as an assessing engineer, it is in favour understanding the production process, the resulting
microstructure and the mechanical properties of the specific material. Any historic iron structure requires
special knowledge about connections, structural design and of course, the material behaviour [2]. The paper
presents these basics and some guiding documents on how to “engineer the past”. Selected representative
heritage structures made of cast iron, wrought iron and early mild iron as well their material- and structurespecific
requirements on rehabilitation are presented. Appropriate assessment procedures, developed e.g.
in technical committees and European projects, allow us keeping the witnesses of the early industrialisation
in service and the surviving structures being still in use. Finally, the background documents prepared in
Europe will be shortly presented to guide the assessment of old iron bridges considering the past but in line
with modern methodology. The background documents support the implementation, harmonization and
further development of the Eurocodes for assessment, not only for design.

Published: February 2021

In the present world people with disabilities wish to be independent and thus the dependence on automatic machinery has increased drastically. People with physical disabilities and partial paralysis find it difficult to navigate without the assistance of someone. The system proposed will be a boost to the physically challenged people as it will help them to be self-reliable. Air gesture model is being as a key component to derive the benefit and gesture recognition is one obvious way to create a useful, highly adaptive interface between machines and their users. The gestures of the hand are read by a camera which is attached to a computer where further processing occurs. Hand gesture recognition technology allows for the navigation of an automobile using only a series of finger and hand movements, eliminating the need for physical contact between operator and machine. If the hand gesture is similar then Arduino is programmed such that the robotic car moves forward. This model can be extended to other areas such as efficient control by traffic corps, patients and senior citizens to call or interact with others, and so on. However, in this paper, the focus will be more as part of driving vehicles.
A REVIEW PAPER ON MEDICAL IMAGE PROCESSING

Published: February 2021

Biomedical image processing has experienced dramatic expansion, and has been an interdisciplinary research field attracting expertise from applied mathematics, computer sciences, engineering, statistics, physics, biology and medicine. Computer-aided diagnostic processing has already become an important part of clinical routine. Accompanied by a rush of new development of high technology and use of various imaging modalities, more challenges arise; for example, how to process and analyze a significant volume of images so that high quality information can be produced for disease diagnoses and treatment. The principal objectives of this course are to provide an introduction to basic concepts and techniques for medical image processing and to promote interests for further study and research in medical imaging processing.The rapid progress of medical science and the invention of various medicines have benefited mankind and the whole civilization. Modern science also has been doing wonders in the surgical field. But, the proper and correct diagnosis of diseases is the primary necessity before the treatment. The more sophisticate the bio-instruments are, better diagnosis will be possible. The medical image plays an important role in clinical diagnosis and therapy of doctor and teaching and researching etc. Medical imaging is often thought of as a way to represent anatomical structures of the body with the help of X-ray computed tomography and magnetic resonance imaging. But often it is more useful for physiologic function rather than anatomy. With the growth of computer and image technology medical imaging has greatly influenced medical field. As the quality of medical imaging affects diagnosis the medical image processing has become a hotspot and the clinical applications wanting to store and retrieve images for future purpose needs some convenient process to store those images in details.

Published: February 2021

The aim of the proposed research consists in outlining prospects of cluster mechanism application and verification of the cluster strategy in view of innovative development of cross-border regions against the background on strengthening integration processes. The work is dedicated to research of theoretical, methodical and applicable basis of strategic management of development of international integration associations as network-like structures of intra-branch and inter-branch cooperation on their mesolevel. The research method is based on mesoeconomic synthesis of development concepts in industrial and innovative clusters and international integration associations. To the authors’ opinion, it enables to work out both mechanism and scientific understanding of development trends in modern integration systems. The scientific hypothesis of the proposed work suggests that the cluster approach is the most efficient mechanism of development of international economic cooperation under modern conditions and, finally, is a mesolevel of competitive international integration systems and necessary pre-condition of qualitative progress of integration of Ukraine into the EU. The authors propose to develop integration processes of mesolevel within the framework of unified economic space basing upon clustering. Concept, structure and life cycle of net forms of self-organization of a cross-border economic space in conditions of developing a postmodern economy are considered. Conclusion is drawn to state that the cross-border clusters concept construes an approach adequate to modern challenges to stimulate economic development of peripheral regions with inherent features and advantages taking into account comprehensive dynamic competition and coordination of problems of meso– and macrolevels with conditions accompanying operation and activity of particular business entities. Under such circumstances, cluster policy consists in creating conditions for formation and development of cross-border clusters, but, under no circumstances, in artificial generation of such clusters. Theoretical positions and methodological approaches to the formation of industrial clusters within European regions are systematized. The essence of cross-border and internal relationships of the cluster as a factor in increasing competitiveness in the increasingly Euroregion integration processes and the need to enhance the role of peripheral regions within the framework of crossborder cooperation. The strategic priorities for spatial development of new forms of cross-border cooperation in the context of regional policy of the EU are outlined.

Published: February 2021

The purpose of the article is to carry out an analysis and improvement of the methodological approach for estimating and forecasting socio-economic devel-opment of regions. The methodological basis of the study consisted of scientific works of domestic and foreign scientists and leading specialists, statistical and analytical materials of state authorities. The results are obtained through the use of such methods as: expert – to identify the impact of qualitative and quantitative indicators on the socio-economic development of the region; economicmathematical analysis – to study the influence of a defined group of indicators on the level of development of the region; abstract-logical – for a theoretical synthesis and formulation of conclusions. The results of the study suggest that the introduction of a sound scientific and methodological approach to assessing and forecasting the level of development of the country and regions in particular will allow not only to identify problem areas in the development of the respective territories, but also to get the potential investor reliable information about the real state of affairs and to determine the justification of further investment in the activity of the research object. Using an unjustified scientific and methodological approach not only can distort the real state of affairs in the regions and the country in general, but also send limited financial resources of the State and local budgets in the conditions of the crisis to improve the indicators that have a minor impact on the development of the economy. It is proved that in current crisis conditions, the functioning of the national economy, state authorities should implement a more effective discretionary fiscal policy aimed at reducing the tax burden in the formation of the wage fund of the socially vulnerable population. The errors, ob-tained during misuse of information technologies in the assessment of socio-economic development of regions are revealed. The scientific and methodological approach to determining the coefficient of competence of experts and the value of 1 point of qualification competences during the construction of forecast scenarios and the development of regional economic development programs using intuitive fore-casting methods has been improved. Proposals for improving the system of taxation of the socially vulnerable population are developed.

Authors: Mazur Iryna , Aliyev Ramil , Zhelizko Yuliia
Published: February 2021

The purpose of the paper is to determine the relationship between different types of tourism safety and security, and components of the tourism entrepreneurship potential, to conduct a quantitative analysis of these indicators in the regions of Ukraine and to identify areas for ensuring the safety and security of the tourism entrepreneurship potential realization. Methodology. Analysis of tourism safety and security in Ukraine is based on the assessment of security potential indicator and the security threats indicator for 25 regions. These indicators take into account the following types of safety and security: security of tourist services, safety of tourist facilities and equipment, social security, political security, financial security, medical safety, information security, and ecological security. The impact of tourism safety and security on the tourism entrepreneurship potential realization is determined on the basis of correlation and regression analysis, where the indicator of the tourism entrepreneurship potential realization is the volume of domestic and inbound tourist flows in the region. The empirical basis of the study is the data of the State Statistics Service of Ukraine for 2019. The reliability of the regression model was tested on the basis of the approximation coefficient and Fisher's F-test. Results of the correlation analysis indicate a significant relationship between ensuring the safety and security of tourism in the region and the volume of domestic and inbound tourist flows. As a result of regression analysis, a model of a high level of reliability was obtained, which indicates how the volume of domestic and inbound tourist flows to the region increases with increasing the level of tourist safety and security by unit. Practical implications. Since the process of safety and security ensuring for the tourism entrepreneurship potential realization cannot be implemented exclusively at the regional level, it is justified the feasibility of a targeted public policy in eight areas. Value/originality. The identified relationship between the types of safety and security of tourism and components of the tourism entrepreneurship potential, as well as establishing the level of impact of safety and security of tourism on the tourism entrepreneurship potential realization in the region provide for a better understanding of ways for efficient governance in this area.
REGIONAL SMART SPECIALIZATION: MICROBUSINESS IMPACT
Authors: Polishchuk Yevheniia , Ivashchenko Alla , Kornyliuk Anna
Published: February 2021

SMART specialization is a basic approach to the development of regional innovation policy. It involves identifying priority sectors of the local economy with the involvement of key stakeholders. Currently, statistics on the development of regions are presented in terms of large business, small and medium. In this context, the generally accepted methodology from the Joint Research Center of the European Commission has limited application. Because it does not take into account the performance of microbusiness (individual entrepreneurs). For countries with economies in transition, this is critical, as they reach 80% of the business structure. Therefore, considering their voice is also necessary. Our approach involves a combination of quantitative (assessment of innovation and economic potential of the region) and qualitative (survey of microbusiness representatives) methods to identify priority areas of SMART specialization. Approbation of the offered method was carried out on the example of the Mykolaiv region which is in the south of Ukraine. The results of the study have shown that the innovation of microenterprises is at a low level. At the same time, they demonstrate a high level of desire to be involved in the process of SMART specialization and innovation of production.
SPATIAL DIVERSITY OF INFRASTRUCTURE AND ITS IMPACT ON THE DEVELOPMENT PROCESS OF RURAL COMMUNES IN EASTERN POLAND IN 2009-2018
Authors: Dziekański Paweł
Published: February 2021

Local government units are developing in an increasingly complex environment that is a place of concentration of economic activity and is a creator of local and regional development. Their activities target all types of resources, i.e., financial, human, material and information. The aim of the article is to rating the diversity of infrastructure of rural communes of Eastern Poland in relation to development. The measurements were carried out using a synthetic measure in a system of 484 communes. Data from the Local Data Bank for 2009-2018 was used as the source material. Development is a general process, multi-dimensional process, covering economic, social, environmental, political and cultural aspects. Regions with a high level of infrastructure development are areas recognized by investors and residents as attractive places for doing business and living. The level of infrastructure development in a given local system in terms of its structure, location, quality and accessibility has a very strong impact on its development. In 2018, the infrastructure measure ranged from 0.23 (best unit) to 0.91 (the weakest unit), and from 0.35 to 0.91 in 2009. In 2018, the measure of development ranged from 0.43 to 0.82, while it ranged from 0.52 to 0.84 in 2009. This indicates a similar range of unit diversity and similar actions undertaken in the economy. Units in the aspect of the measure of development and infrastructure differed the least in the aspect of entrepreneurship, demography and labor market as well as the financial situation, and the most in the aspect of infrastructure and development. The level of infrastructure of Eastern Polish rural communes was shaped primarily by the development process and financial situation but also by the number of people costing from libraries, sewage system and water supply as well as housing resources.
CONCEPT OF “HIDDEN ASSETS” AND METHODOLOGICAL BASES FOR THEIR ASSESSMENT
Authors: Burkynskyi Borys , Goryachuk Valeriy , Nazarenko Julia
Published: February 2021

To assess the prospects of an enterprise and plan its activities, it is very important to know what assets it has, including hidden assets. Today, there is no single understanding of this concept. Some researchers attribute this to an underestimation of the company’s assets, others – to a lack of accounting for assets, or to insufficient use of assets. This is the result of applying various methodological approaches and insufficient research of this concept. On the ground of a methodological approach based on the identification of generic concepts and essential features, a generalized definition of the concept of “hidden assets” is proposed. These are assets, value of which on the company’s balance sheet is undervalued compared to their real value, or which are not reflected in the balance sheet, or which are underutilized and which are real assets, and which are capable to provide a competitive advantage or economic benefit. This definition of the concept of “hidden assets” allows to combine different existing points of view on this concept and to look at the capital of an enterprise in a broader context. The difference between the concepts of “hidden assets” and “accounted assets” from the point of view of law is considered separately. Assets that are recorded in the balance sheet belong to the enterprise based on ownership rights. As for hidden assets, as a rule, the enterprise in relation to them has the right to use only. Firstly, this applies to the leased fixed assets, human capital (use of time, knowledge and skills of specialists). In other words, the right to use is of crucial importance. In this case, the assets of the enterprise are considered as a set of rights to receive economic benefits. With such a broad view, the components of the hidden capital of an enterprise can be identified. Analysis of existing methodological approaches to the assessment of hidden assets has shown that they have significant methodological shortcomings and difficulties in applying and collecting the necessary initial data. Methodological bases for estimation of hidden assets are proposed based on the defined concept of “public value of an enterprise” as the sum of all assets used by an enterprise to create gross value added. Calculations have shown that the average share of hidden assets of Ukrainian enterprises in the period from 2012 to 2018 in the total volume of all assets is 33.7 %, and by type of economic activity from 14.3 % in construction to 70.1 % in agriculture. Hidden assets are the missing link in determining the level of capitalization of an enterprise. All other things being equal, the difference in the level of economic development of enterprises can be explained by differences in the volume and structure of their hidden assets. Hidden assets can be the key to creation of an enterprise’s development strategy.
