Potential of Brownfields as Developing Territories in Bratislava
Authors: Golej Julius , Panik Miroslav
Published: January 2019

The issue of brownfields and their analysis in Slovakia have not been given such emphasis over the last decade as in the neighbouring EU countries, such as in Austria or in the Czech Republic. The situation is completely different in Bratislava and also in the rest of Slovakia and the development of this type of area is almost unrealized. A frequent argument is problematic ownership relationships to the unused, degraded land. However, the real problem is the higher financial costs associated with brownfields regeneration. Despite this fact, brownfields can be considered as an area with relatively large development potential within the urbanized area and one form of hidden reserves of both, local and national economy. Among the indisputable benefits of using brownfields, we can include reduction of the extensive land use of agricultural land for rural area. In the long run, Bratislava is preparing a search study of neglected and unused land within the capital. It is due to be completed in the course of 2018, and will be an important basis for a new territorial plan and the development of Bratislava. In the following article, we analyse brownfield land in Bratislava. The already realized brownfield projects are also mentioned, while we are trying to point out their main advantages and disadvantages.

Published: January 2019

The article discusses the current state of forest land, the history of formation of large tracts of forest in the Samara region and analyses some of the results of implementation of target programs to improve the forest cover in the region under the Kyoto Protocol. This program was designed for the period from 2006 to 2015, but in 2009 was discontinued. However, large segment of assets was allocated and a number of works was carried out. Currently the objectives of the programme to increase the forest cover in the territory of Samara region through the creation of tracts of forest are not achieved. Tree and shrub plantations play an important role in reducing the activity of processes of erosion, prevent degradation and desertification. Therefore, the problem of increasing forest cover, especially in the steppe zone of the region, to the level of the preindustrial era remains relevant and requires science-based measures for their solution.

Published: January 2019

Railway tracks require more thorough maintenance and analysis than regular roads for cars. Defects are here noticed and recorded by using special equipment. Construction of railway roads and their exploitation requires optimal accuracy and monitoring of surveying. It is related to maximum allowed speed of trains, the environment, transport and human safety. In order to highlight complex problems of railway road exploitation, the evaluation of railway roads was conducted. Problem areas of railway maintenance were identified. Their monitoring needs to be improved by applying geodetic devices for surveying. Comparing analogous surveying conducted using EM140 machine with that of geodetic equipment, one can see the advantage of geodetic surveying. Technical gaps in the surveying process, data storage and procession were evaluated as well. It was discovered that maintenance and monitoring works should be pursued more frequently using high accuracy geodetic equipment.
Key words: railway, geodetic surveying, accuracy of surveying, EM140.

Published: January 2019

The research studies the issue of ecological stability of rural territories that is the most important component of the national environmental policy of Ukraine. A special attention is paid to degradation of arable lands as the main ecological problem of land management. On the example of Lviv region, the authors calculated the index of ecological nonconformity of current use of arable lands, proving a considerable excess of permissible ploughing of lands in the region. The carried analysis confirms that no measures were performed concerning land protection, including conservation that in the recent years. In this context it is necessary to improve land resources management on the basis of sustainable development. Integration is considered to be the main principle of land resources management. The research proves that solution of ecological problems of land management requires achievement of a set of coordinated targets concerning development of rural territories, land resources management and national environmental policy based on the principles of suitable development. The targets include: planning of land use outside settled areas on the landscape and ecological basis; land inventory; formation of the land bank of agricultural lands; development and support of alternative kinds of activity on rural area; development of an efficient mechanism to encourage performance of land protection measures; improvement of environmental responsibility of population and development of ecological education. The methodological basis of the research is the concept of sustainable development, which expects support for a continuous character of development in order to meet the current needs along with ensuring the needs of future generations. The fulfilment of the task requires examination of scientific works on the issue of sustainable management of land resources and an ecological component of rural territory development.

Published: January 2019

The cross plotting of rock properties for fluid and lithology discrimination was carried out in a Niger Delta oil field using well data X-26 from a given oil field in the coastal swamp depobelt. The data used for the analysis consisted of suites of logs, including gamma ray, resistivity, sonic and density logs only. The reservoir of interest Horizon 1, was identified using the available suite of logs on the interval where we have low gamma ray, high resistivity and low acoustic impedance specifically at depths 10,424ft (3177.24m) to 10 724ft (3268m). We first obtained other rock attributes from the available logs before cross plotting. The inverse of the interval transit times of the sonic logs were used to generate the compressional velocities and the S-wave data was generated from Castagna´s relation. Employing rock physics algorithm on Hampson Russell software (HRS), rock attributes including Vp/Vs ratio, Lambda-Rho and Mu-Rho were also extracted from the well data. Cross plotting was carried out and Lambda Rho (λρ) versus MuRho (μρ) crossplots proved to be more robust for lithology identification than Vp versus Vs crossplots, while λρ Versus Poisson impedance was more robust than Vp/Vs versus Acoustic impedance for fluid discrimination, as well as identification of gas sands. The crossplots were consistent with Rock Physics Templates (RPTs). This implies the possibility of further using the technique on data points of inverted sections of various AVO attributes within the field in areas not penetrated by wells within the area covered by the seismic.

Published: January 2019

The article presents the present situation in terms of energy production from renewable energy sources and perspectives for development, based on research on the existing resources and possibilities of using them. The Lubusz Voivodship is not an important energy producer in Poland. In terms of the amount of energy produced it comes twelfth out of sixteen voivodships. The annual energy production from renewable energy sources is 290,9 GWh, which is 11.6% of the total energy produced. At the end of 2014 there were 73 licensed installations producing electrical energy from renewable energy sources in the Lubusz Voivodship with a total capacity of 189 MW. The largest amount of energy is produced by a pumped storage power plant (91,3 MW). The total capacity of the licensed installations using RES in the Lubusz Voivodship rose from 103 MW in 2007 to about 189 MW in 2014. Research on the existing resources indicates that it is possible to develop RES. Preparations are under way to build 66 new wind farms with a total capacity of 1834 MW [35], 89 photovoltaic power plants with a total capacity of 468 MW, 21 water power plants with a total capacity of about 60 MW, 54 biogas power plants with a total expected capacity of about 67 MW. The total capacity of the RES installations that are planned to be built by 2023 will be 2469 MW. Therefore, in the coming years the installed capacity of RES installations will increase 13 times in the Lubusz Voivodship. There are still no plans to use the energy of deep geothermal waters due to low profitability.

Published: January 2019

Due to the significant role and noticeable development of transportation routes running from the north to the south of central Europe, several problems related to the construction and functioning of roads in the Carpathian foothills have been revealed. Recent climate change causes areas, where transport routes are particularly exposed to hazards, to succumb to technical exploitation and degradation. The elimination of the threats related to the activation of landslide phenomena becomes particularly expensive. Old roads, which were once designed for significantly lower axle loads and less heavy traffic conditions, are predominantly exposed. At the present, these roads are heavily exploited and have become overloaded. As a result, both the roadway and the subgrade undergo damage, which causes an increase in dynamic loads, and in potentially endangered areas, the activation of landslides. Landslides in the Carpathian flysch have a peculiar susceptibility to activation due to its geological structure. This paper addresses the problem of monitoring and analysing the effects of a landslide associated with the operation of a transportation route running through the slope of the Carpathian flysch. The studies include both field work and laboratory testing of basic geotechnical parameters. The parameters obtained during the geotechnical investigations, conducted for the purpose of building a numerical model, have been completed. The field work includes surveys made by a terrestrial laser scanner. The study also includes a number of 2D and 3D numerical models. These models, along with the substrate parameters, have been introduced into the FEA package and then calibrated. Subsequently, an analysis of the effects of landslide susceptibility and the behaviour of the road and terrain surface, due to the different variants of the loads, is shown along with the results of surveys.

Published: January 2019

ART (Adaptive Resonance Theory) networks were invented in the 1990s as a new approach to the problem of image classification and recognition. ART networks belong to the group of resonance networks, which are trained without supervision. The paper presents the basic principles for creating and training ART networks, including the possibility of using this type of network for solving problems of predicting and processing measurement data, especially data obtained from geodesic monitoring. In the first stage of the process of creating a prediction model, a preliminary analysis of measurement data was carried out. It was aimed at detecting outliers because of their strong impact on the quality of the final model. Next, an ART network was used to predict the values of the vertical displacements of points of measurement and control networks stabilized on the inner and outer walls of an engineering object.

Group exams have been shown to improve student performance, retention of material, and teamwork and communication skills. This paper assesses the opinion of students regarding group exams, and their perception of potential benefits and impacts on their learning, before and after having participated in one. Both a traditional and two-stage exam were performed in first-year physical chemistry courses in the engineering stream of Vantage College at UBC, which means the participating cohort is entirely composed of international students with a range of English-language communication skills.The overall experience of students with group exams, based on survey responses, was positive, and the large majority of students indicated they would like to continue using this format of exam in the future. The perception of group exams improved before and after having written one, with the students initially overestimating the difficulty, stress, and level of conflict associated with this process. Some students indicated less confidence that peer learning helped them improve their performance after having written the exam, but further study to elucidate the significance and the causes of this result.
The Right Tools for the Job: Discipline-Specific Language-Learning for First-Year International Engineering Students
Authors: Pringle John , Potvin Gabriel
Published: January 2019

Vantage College at UBC offers specialized first-year programs for international students that integrate core disciplinary courses with complementary language education to allow students to develop their communication skills before joining their direct-entry counterparts for the remainder of their studies. This paper builds on the partnership between two first year engineering chemistry courses and their adjunct language courses, in which the instructors work closely together to accomplish mutual learning objectives. As a measure of the effectiveness of this integrated approach on the development of discipline-specific communication skills, the frequency of specific language error types are tracked in student’s lab reports, across two terms, and students report through a survey their perception of how this integrated approach helped them develop their technical communication skills. Overall, as indicated by both significant reductions in the frequency of several error types, as well as the responses provided by students, this integrated approach is effective, and the data suggests key areas of focus for further improvement.
Humanitarian Engineering: A New Interdisciplinary Course on the Application of Engineering Skills to Local and Global Humanitarian Challenges
Authors: Sheroubi Andrew , Potvin Gabriel
Published: January 2019

Many students express a desire to apply their technical engineering skills to produce positive societal impacts, and although sustainability frameworks do take this into consideration in traditional engineering curricula, there are relatively few avenues for students to work on real global social issues during their undergraduate studies. This paper describes a new interdisciplinary course developed at UBC on the use of engineering skills to solve humanitarian challenges.The course is composed of case-study analyses, interactive activities and simulations, group discussions and seminars, and a technical design project completed in partnership with an NGO or charity working on a particular humanitarian challenge. The rationale and design of the course and its deliverables, as well as student feedback on this first iteration of this course are presented.
Common First-Year Engineering Curriculum in British Columbia
Authors: Dick Brian
Published: January 2019

Labour market demand for engineers  continues to outpace the capacity of postsecondary institutions to produce new entrants to the field.  Providing for the diverse pathways students may take for their education could both increase the numbers of potential candidates, as well as improve the likelihood of those candidates successfully completing engineering programs. The British Columbia Council on Admission and Transfer (BCCAT) Engineering Articulation committee leveraged overlap within the content and delivery requirements of first-year engineeringprograms at most engineering schools in the province and developed a sector-wide common first-year engineering curriculum
Using Concept Maps to Facilitate Deep Learning in a Third Year Geomatics Engineering Course
Authors: Rangelova Elena
Published: January 2019

This paper examines the use of concept maps (a graphical tool used for organizing structured information) to assist students in learning abstract and difficult concepts in a third year geomatics engineering course. Students often describe the material in this course as “difficult to understand” and “it contains lots of complex concepts”. Therefore, their learning cannot always be described as deep learning; rather, students tend to resort to surface learning in order to deal with the high complexity of the course material. The term deep learning originates from the fundametal work by Marton and Säljö, who investigate how students respond to academic tasks. Engaging in deep learning means that a student is able to organize new information in a structured way and link it to previous knowledge.
Using an Academic Plan Model to Analyze Canadian Engineering Leadership Curriculum
Authors: Klassen Mike , Donald John
Published: January 2019

This paper analyzes engineering leadership curriculum in Canadian universities. Using an adapted framework for curriculum development, we analyze key documents for six engineering leadership programs in six different universities. Findings show a wide range of purposes, content and sequencing, with a common core of instructional processes and resources. We explore how accreditation, labour markets, internal resources and relationships with business schools shape curriculum decisions. Future work will explore deeper connections between influences and the curriculum, and comparisons between Canada and other jurisdictions.
The construction of a digital platform aggregating active learning strategies for engineering education
Authors: Morin Sophie , Farand Patrice
Published: January 2019

Communities of practice are supporting growth, development and collaboration in various environments. A new Chair in teaching and learning at Polytechnique Montreal, focusing their activities on active learning strategies, perceived useful and relevant to build a community of practice around this widespread academic topic. To achieve this goal, they built a repertoire of active learning strategies to stimulate meetings and encourage exchanges between engineering educators.The ultimate objective is to promote the use of active learning strategies, which are more effective than the traditional ones, to enable in-depth and lasting learning. Many success factors and integration challenges concerning this type of approach have been studied and are considered and addressed with this new instrument.Francophone teachers from all around the world, will be able to share their experiences with active learning in an engineering context as well as learn from and teach to others in the community. The platform’s effectiveness as a collaborative tool will be studied and measured with an action research protocol, analyzing quantitative and qualitative data.
The Experiences of Women in Undergraduate Engineering

While it is understood that there is an issue in retention of women in STEM fields, there is little research addressing why this is occurring. This warrants the need to begin identifying the root of this issue, and the direct causes. Undergraduate engineering programs are the first phase students undertake in their pursuit of a career as a professional engineer, and even in this early phase an issue in retention is apparent. The present study addresses factors that may be preventing female students from remaining in the field. In this study, 261 undergraduate students enrolled in engineering programs at an accredited university in Ontario completed a 17-question survey that collected demographic data and asked questions related to challenges students may experience during their education. The survey questions were formulated to understand the severity to which each challenge affects males and females in different ways. Demographic factors were correlated with students’ answers, and significant differences between men’s and women’s answers were found. 65% of female students reported more discouragement or intimidation by peers and professors in their program, compared to 45% of male students. These findings may indicate that female students may be more susceptible to a culture of intimidation than male students. Another significant finding lies within a survey question formulated to understand if female and male engineers have their contributions represented equally. This question showed that male students recognized the names of male engineers 1.75 times more often than they recognized the names of female engineers. The results of this question show that, to some capacity, male engineering students do not recognize female engineers’ contributions as frequently as male engineers’ contributions. Moving forward, there is a need to support female students in engineering as well as to educate students on respect and equity.
Thinking About Learning – Inferences from How We Support Curriculum Design
Authors: Stubley Gordon
Published: January 2019

Over the past 40 years there has been the development of well-structured workshops and educational movements to aid faculty members’ teaching development. The present study is a reflective analysis of a set of five well-established teaching development initiatives with the hope of inferring how engineering educators collectively think about students’ learning.The content of the initiatives is organized into two broad groups: teaching strategies and characteristics and attributes of student learning. Analysis shows that all of these initiatives emphasize teaching strategies and put much less emphasis on developing understanding of student learning beyond emphasizing two broad general principles on student learning: teaching should be student-learning centred, and learning for mastery requires purposeful active intellectual effort. However, beyond this there is little attention given to aligning teaching strategies with the cognitive mechanics occurring during learning. These initiatives seem to imply that faculty members should teach with a primary focus on student learning but that the details of the learning mechanics are of lesser concern in planning and delivering our courses.This analysis leads to the open question: “Would a better understanding of the cognitive mechanisms involved in learning allow educators to better align teaching strategies with the needs of student learning and to adapt to evolving student characteristics?

In order to help the students of the Faculty of Engineering at the Université de Sherbrooke within the field of product design in engineering, the Laboratory for the Characterization and the Validation of Prototypes (LCVP) has been created. The facilities feature most of the resources needed to conduct experiments toward the estimation and measurement of critical parameters and specifications along the design process but also toward the final validation of a product design. To that end the support of a professional researcher is provided to advise the students toward the proper implementation of their test benches. Overall, the LCVP provides state-of-the-art equipment and competent resources to the students from various departments at both undergraduate and graduate levels therefore improving their product design experience, while enhancing their competencies. This is indeed a unique feature of the LCVP, setting it apart from other initiatives targeted at supporting capstone and student projects.
