Authors: López Jiménez Víctor Leonardo , Rojas Castro María Alejandra , Pérez Prieto Katherine Gineth
Published: January 2020

La carencia de información meteorológica o la falta de calidad en la misma, causa deficiencia en el desarrollo de estudios e investigaciones sobre la afectación del entorno natural y específicamente en los sistemas de producción agropecuaria. Por esta razón, se hace necesario evaluar las condiciones de la red meteorológica que provee de información al sector agropecuario, con el fin de consolidar una base de datos consistente que se constituya en un verdadero soporte para la toma de decisiones relacionadas con la disminución del riesgo y los efectos de la variabilidad y el cambio climático en el sector agrícola y ganadero.En el desarrollo del proyecto se analizó la información disponible en las bases de datos del IDEAM y la CAR, instituciones que operan en mayor proporción las estaciones de la red agrometeorológica en Cundinamarca. Al tiempo que se adelantó la compilación de la información, se realizaron las visitas de campo con el fin de obtener de primera mano información sobre la operación de las estaciones utilizando herramientas de investigación como las encuestas a los observadores de superficie. Con base en las publicaciones de la Organización Meteorológica Mundial - OMM y el IDEAM, se determinó la metodología que mayor ajuste tuvo al objetivo de mejoramiento de la red meteorológica con fines agrícolas del departamento de Cundinamarca. Con estos criterios definidos y teniendo en cuenta el estado actual de las estaciones que operan en el departamento, se elaboró la propuesta de mejoramiento de la red agrometeorológica mínima.
Iterative Learning Control Based Fractional Order PID Controller for Magnetic Levitation System
Authors: Hanif Bushra , Shaikh Inam-ul-Hassan , Ali Ahsan
Published: January 2020

Maglev (Magnetic Levitation) systems are an interesting class of systems since they work without any physical contact and are hence frictionless. Due to this attractive property, such systems have the potential for wide range of applications such as maglev trains. Maglev is non-linear due to magnetic field and unstable that suggest the need of stabilizing controller. An appropriate controller is required to levitate the object at desired position. FOPID (Fractional Order Proportional Integral Derivative) controller and ILC (Iterative learning Control) based FOPID controller are designed in this paper for the levitation of metallic ball with desired reference at minimum transient errors. Since maglev is unstable and ILC is used only for stable systems, FOPID controller is used to stabilize the plant. Non-linear interior point optimization method is used to obtain the parameters of FOPID controller. An ILC is used as a feedforward controller in order to improve the response iteratively. P, PD and PID-ILC control laws are used to update the new control input in ILC based FOPID controller. The overall control scheme is therefore a hybrid combination of ILC and FOPID. The effectiveness of proposed technique is analyzed based on performance indices via simulation. ISE (Integral Square Error) and IAE (Integral Absolute Error) is lesser in case of hybrid PID-ILC as compared to simple FOPID controller.

Published: January 2020

WSN (Wireless Sensor Network) comprises of small-sized and constraint-capability SN (Sensor Nodes) which record, send and receive data, sensed to a sink. The network lifetime and energy usability are important challenges to be dealt with. During the working of the SN, the maximum amount of energy is consumed than sensing and processing of data. Therefore, an efficient transmission of the data is required so that the energy can be saved. In this paper, a novel routing and scheduling method for WSNs using GA (Genetic Algorithm) is presented, where the sinks employed on four sides of the sensor field. These sinks collect the data from the SNs having the optimal distance towards the respective sink. The proposed scheme finds the optimized path using GA, during transmission of data from SN to the nearest sink. First, we run the GA for determination of routing paths, where a source SN finds the possible number of optimal hops. Second, the hops or intermediate relay SNs are assumed to relay the data towards the sink, efficiently. The performance is experimented and evaluated using MATLAB R2016b. The simulations have carried out through comparing the proposed scheme with TEEN (Threshold Sensitive Energy Efficient Sensor Network Protocol). The results of simulation comprise of 10 and 20 number of SNs, discretely. Additionally, the direct distance of each node is calculated and the distance through multiple hops from/to the nearest sink is also evaluated. The achievements of the proposed technique are to save both energy and distance for the sake of network longevity and optimal and precise data delivery by multiple hops.

Authors: Tariq Nida , Ijaz Iqra , Malik Muhammad Kamran , Malik Zubair , Bukhari Faisal
Published: January 2020

Urdu literature has a rich tradition of poetry, with many forms, one of which is Ghazal. Urdu poetry structures are mainly of Arabic origin. It has complex and different sentence structure compared to our daily language which makes it hard to classify. Our research is focused on the identification of poets if given with ghazals as input. Previously, no one has done this type of work. Two main factors which help categorize and classify a given text are the contents and writing style. Urdu poets like Mirza Ghalib, Mir Taqi Mir, Iqbal and many others have a different writing style and the topic of interest. Our model caters these two factors, classify ghazals using different classification models such as SVM (Support Vector Machines), Decision Tree, Random forest, Naïve Bayes and KNN (K-Nearest Neighbors). Furthermore, we have also applied feature selection techniques like chi square model and L1 based feature selection. For experimentation, we have prepared a dataset of about 4000 Ghazals. We have also compared the accuracy of different classifiers and concluded the best results for the collected dataset of Ghazals.

Chinaâ€™s Progress in Poverty Reduction: What Can South Africa Learn from China to Attain the Poverty Eradication Goal in the Sustainable Development Goals?
Authors: Mubecua Mandla Abednico
Published: January 2020

During the evaluation of the Millennium Development Goals (MDGs) from 2000 to 2015, it was discovered that there was no country managed to meet the envisioned goal of eradicating poverty. However, it was observed that China is the only country that managed to half its poverty levels. Just like other developing countries, South Africa is one of the countries whose performance in the attainment of the first goal of MDGs was not satisfactory. Through the utilization of secondary data in a qualitative approach, this paper argues that South Africa can perform better if it can learn and follow the strategies used by China to shrink its poverty levels. The study shows that China mostly supports State Owned Enterprises, which make the economy to grow and help in poverty alleviation. For that reason, the study recommends that in order for South Africa to attain the poverty eradication goal by 2030 more SOEs have to be established.
An Analysis of Nation Brand Attractiveness: Evidence from Brand Zimbabwe
Authors: Masango Cleven , Naidoo Vannie
Published: January 2020

This paper examines the attractiveness of Brand Zimbabwe based on the factors perceived to impact on national competitiveness. Nation brand attractiveness is a necessary condition for a country to achieve influence and to effectively compete for global resources. Countries can enhance their attractiveness by building on their national brand equity and dealing with negatives around the national brands. The research sought to determine the perception towards Zimbabweâ€™s global risk and competitiveness; to ascertain the variables that promote competitiveness for Brand Zimbabwe and to contribute to the literature on risk perception and its impact on behaviour towards nation brands. The study followed a mixed approach; a combination of interpretivism and positivism. The research drew 372 respondents from politicians, scholars, the media, civic organisations, government officials, church and international organisations. The research established that Brand Zimbabwe faces glaring threats risks that impact on the countryâ€™s international image. The brand is affected by politics and governance together with socio-economic factors. Management and control of nation brand perception are critical for nations to distinguish themselves and to create vantage positions for sustainable performance. The way a country is viewed internationally is a function of how the country deals with factors that threaten its global competitiveness and perception towards the nation brand. Zimbabweâ€™s quest for foreign direct investment, international visitation and export revenue requires that the country deals with its nation brand image.

Published: January 2020

The focus of this survey is to seek the amount of the customersâ€™ expectations levels of service quality in the public Technical Vocational Education and Training (PTVET) sector. The aim of this study was to examine and determine the expectations and perceptions levels of service quality provided by PTVET colleges, in order to achieve desired outcomes, and the survey followed SERQUAL model. Questionnaires were distributed to the 403 participants from selected PTVET in the Kwa-Zulu- Natal province. The study used a mix approach of systematic and quota sampling techniques. SPSS (25.0) version was employed for data analysis. The results of this study discovered that customers had higher service quality expectations (0,908 Cronbach's Alpha) compared to the service quality perceptions (0,923 Cronbach's Alpha) at the selected PTVET colleges, on all five service quality dimensions that were used to evaluate the expectations of service quality. This survey will benefit Rectors/Campus Managers for TVET colleges and to those who want to open their TVET colleges, because it will be used as a guide tool for them on how they can improve service quality strategy to differentiate themselves from their competitors. The findings are limited by the studyâ€™s exploratory, quantitative nature and small sample. Generalisation should be done with care and further research, with a large sample and consideration of other provinces, it therefore recommended.
Subjective Risk Tolerance of South African Investors
Authors: Dickason-Koekemoer Zandri , Ferreira SunÃ©
Published: January 2020

In general, the amount of risk an individual is willing to tolerate can be influenced by demographic factors. However, needs for research arise as to whether demographic factors influence the amount of risk investors in South Africa are willing to tolerate. The survey was conducted in 2017 and all South African investors were included in the sample frame. For this study, a sample of 800 was collected and used. Multinomial regression was used to indicate whether there were more than two factors that can influence the four risk tolerance levels of South African investors. The study suggested that gender is a determining factor in the risk tolerance of individuals. African investors were more likely to take the substantial financial risk. Age was also a determining factor of risk tolerance which follows the assumptions of the investor lifecycle where younger investors are more risk tolerant. The study furthermore found that higher annual income attracts more risk-taking while lower-income attracts more risk averseness in individuals. It was lastly observed that married individuals and those that are no longer married will be more likely to be risk-averse. This study makes a significant contribution in profiling investors risk tolerance according to their demographic factors whereby financial institutions can offer more tailored investment options.

Authors: Feng Yang , Ye Wenhua , Lu Qian , Xiao Leiming
Published: January 2020

Aiming at the problems of low system efficiency and high energy consumption of nodes in the current explosion-proof control system for liquefied gas tank leakage, a data fusion-based explosion-proof control system for liquefied gas tank leakage is designed. The function design of the explosion-proof control system for liquefied gas tank leakage is completed through personal information management, authority management, basic data management, detection and alarm design and control design. In software design, data fusion algorithm is used to fuse the underlying data of the system, which saves data traffic and ensures the normal functioning of the mobile terminal. The specific step is to use the local estimation of each independent sensor in the multi-sensor network, give each sensor a weighted value according to the approximation of the true value, and finally integrate all local estimates to get the whole system. Through function design and software design, the design of explosion-proof control system for liquefied petroleum gas tank leakage is realized. The experimental results show that the system has the advantages of low node energy consumption and high system efficiency.

On power of control chart for the ratio of two Poisson distributions under misclassification error
Authors: Chakraborty Ashit , Khurshid Anwer
Published: January 2020

When the control charts for the ratio of two Poisson distributions need to be constructed, a situation may require controlling the ratio rather than a single parameter. Chakraborty and Khurshid [6] constructed Shewhart control chart and Chakraborty and Khurshid [7] studied measurement error effect on control chart for the ratio of two Poisson distributions, respectively. The effects of misclassification on the performance of control charts have been investigated by several authors. Measurement error variability has uncertainty that can arise from several sources. In this paper, we study the effect of the two sources of variability on the power characteristics of control chart under misclassification error for the ratio of two Poisson distributions as studied by Sahai and Khurshid [36]. Probabilities of misclassification of conforming and non-conforming units for grid of values are provided.
Experimental Investigation and Simulation of Aircraft Tire Wear
Authors: Kahms Stephanie , Wangenheim Matthias
Published: January 2020

Not only in the automotive sector, but also in the field of aircraft tires, the topic of abrasion is of great importance. The aircraft tire manufacturers provide criteria for the permissible degree of wear. If these limits are exceeded, the tire must be replaced or retreaded. By this time, the tire should withstand as many takeoff and landing cycles as possible. Abrasion models should help to predict the wear behavior in preflight modeling.

At the Institute of Dynamics and Vibration Research, quasi-steady abrasion tests are performed using tread block samples from an aircraft tire. For various pressures and sliding speeds, the abrasion is determined by recording the mass loss of the rubber sample. Based on these measurement data, a wear model is derived as a function of coefficient of friction, contact pressure, and sliding speed for different ambient temperatures.

The well-known brush model forms the basis for the wear simulations. With parameters validated on the aircraft tire, such as contact length, stiffness, and friction coefficient, the resulting mechanical forces within the contact area are calculated. Finally, the classic brush model is extended by the abrasion calculation. The tire wear is determined during unsteady load and slip conditions by use of the quasi-steady wear maps derived from our experiments. Within a measurement campaign on the complete tire, the tread depth is measured after various driving maneuvers and is in good agreement with the simulation results.
Effect of droplet transfer on pore formation in laser-pulsed metal inert gas hybrid welding of A7N01P aluminum alloy
Authors: Huang Shuang , Yang Xiaoyi , Chen Hui , Cai Chuang , Xu Lidong
Published: January 2020

The effect of welding parameters on the pore formation in laser-pulsed metal inert gas (MIG) hybrid welding of A7N01P-T4 aluminum alloy was investigated. The formation and dynamic behavior of keyholes at different wire feeding speeds were studied using a “sandwich” structure consisting of GG17 glass and A7N01P-T4 aluminum alloy. The types and morphology of pores were analyzed using scanning electron microscopy and an x-ray nondestructive tester. The experimental results indicated that the droplet transfer mode affected the stability of the keyholes. The barrier effect of the large droplets on the laser could cause the bottom of the keyholes to close, forming keyhole-induced pores in the molten pool. The size of the droplet decreased with increasing wire feeding speed; thus, the selection of an appropriate wire feeding speed in laser-pulsed MIG hybrid welding could reduce the barrier effect and effectively reduce the formation of processing pores in the welding seam.

A mission statement should be an expression of the values which a given organisation considers to be crucial in its operations and it should also indicate what needs to be done to realise the strategic vision in a predetermined period of time. A strategic vision represents the managers’ concepts and beliefs related to the long-term direction of the organisation, it is focused on the objectives which are expected to be achieved and determines the organisation’s scope of operation or the place where it plans to be in the future. The strategic mission reflects the organisation’s aspirations, whereas the mission statement informs how the organisation intends to realise them. As it determines the future for the organisation, the vision includes postulates in accordance with which the organisation meets the needs of its clients. Then, the mission identifies the clients, their needs and the manner in which the organisation will cater for them.
Future Challenges of the Convention Bureau
Authors: Celuch Krzysztof
Published: January 2020

The operation of convention bureaus as specific destination marketing organisations faces numerous challenges. These are associated with the formal aspect of managing such an office, establishing it in particular structures, budgeting, presenting a return on investment, as well as substantive aspect of the operations. The meetings industry is constantly changing and developing, and organisations whose work is related to this sector must be tremendously dynamic and ready to find solutions and proposals in response to the changing reality. In order to define the challenges related to the financing of convention bureaus’ operations and managing these organisations, what needs to be indicated first is the lack of cooperation between entrepreneurs representing local business and institutions responsible for particular components of the local tourist product (including offers for event organisation). The effect of the cooperation between these two groups of stakeholders should be a coherent offer, updated on an ongoing basis and adjusted to the changing trends in the meetings industry and to the expectations of potential organisers in the procurement process.
Managing the Selling and Marketing of the Destination
Authors: Celuch Krzysztof
Published: January 2020

Managing a destination as an event venue and conducting marketing activities building its position in this area constitutes the main part of the realisation of a convention bureau mission. Concentrating on the meetings industry requires, above all, direct sales – these are activities based on relations and real time contact. It would seem that the specificity of the meetings industry requires operations only in the B2B sector, but in fact convention bureaus usually undertake activities addressed at consumers, event participants, as the target recipients. Thus, a success-oriented convention bureau must master marketing both by means of traditional mass consumer marketing as well as by direct sales. To perform these activities well requires good planning. The reason for the existence of convention bureaus is the sale of destinations (states, regions, towns or cities). The art of being a modern leader is managing image-building activities (or brand-building activities) as well as sales activities. Consequently, managing destination marketing starts with creating an annual plan to guide the marketing. It is the first step in the annual cycle of the marketing and sales tasks of convention bureaus.

Piramidisasi gen adalah upaya untuk menggabungkan beberapa gen yang menguntungkan dari banyak tetua menjadi satu genotipe tunggal. Hasil tinggi, tahan terhadap wereng cokelat, kandungan amilosa sedang, umur genjah dan aromatik adalah beberapa sifat yang diharapkan untuk digabungkan. Melalui teknik piramidsasi, telah diperoleh 28 genotip, namun analisis kekerabatan genetik, sebagai pertimbangan dalam pengambilan keputusan pada tahapan pemuliaan selanjutnya, belum dilakukan. Kombinasi gen ini dicapai dengan persilangan banyak genotipe tetua dengan karakter unggul yaitu Sintanur (aromatik), Pandan Wangi (aromatik), IR64 (kandungan amilosa sedang), PTB33 (tahan wereng coklat), Ciapus (hasil tinggi) dan KA (umur genjah). Tujuan percobaan ini adalah untuk memperoleh hubungan genetik genotip dalam sifat-sifat agro-morfologi dan marka molekuler. Analisis hubungan kekerabatan antara tetua dan 28 genotip piramidisasi dilakukan menggunakan software XLSTAT2016 untuk membentuk matrik similarity shared allele distance dengan koefisien Jaccard sebagai pembentuk jarak genetik untuk marka molekuler dan koefisien korelasi pearson untuk marka fenotipik. Kemudian dilakukan pengelompokan atau clustering dengan metode Unweighted Pair Group Method with Arithmetic Averages (UPGMA). Hasil pengelompokan berdasarkan marka molekuler dengan menggunakan 11 marka yang terkait erat dengan tujuh karakter target, diperoleh koefisien kemiripan sebesar 41,3% dan terbentuk dua kelompok, sedangkan hasil pengelompokan berdasarkan marka fenotipik dengan 14 karakter agro-morfologi terbentuk tiga kelompok dengan tingkat kemiripan 22,2%. Genotipe SPxCAKA1B, SPxPP3B dan PPxIP4B   dapat dimanfaatkan sebagai tetua atau genotipe harapan karena memiliki jarak kekerabatan yang paling jauh diantara genotip lainnya.

African swine fever virus – the possible role of flies and other insects in virus transmission
Authors: Fila Mateusz , Woźniakowski Grzegorz
Published: January 2020

African swine fever (ASF) is an acute viral haemorrhagic disease of pigs and wild boars. It presents a serious threat to pig production worldwide, and since 2007, ASF outbreaks have been recorded in the Caucasus, Eastern Europe, and the Baltic States. In 2014, the disease was detected in Poland. ASF is on the list of notifiable diseases of the World Organisation for Animal Health (OIE). Due to the lack of an available vaccine and treatment, the countermeasures against the disease consist in early detection of the virus in the pig population and control of its spread through the elimination of herds affected by disease outbreaks. Knowledge of the potential vectors of the virus and its persistence in the environment is crucial to prevent further disease spread and to understand the new epidemiology for how it compares to the previous experience in Spain gathered in the 1970s and 1980s.

Published: January 2020

Due to increasing bacterial antibiotic resistance and the consumers’ tendency to choose organic products, cattle farmers are interested in alternative methods of calf diarrhoea treatment. This is a major challenge for veterinarians. Few methods of non-antibiotic treatment that bring satisfactory results have been reported in the related literature so far. In this article, the authors compare different non-antibiotic methods of diarrhoea prevention and treatment in calves. Among the alternatives discussed are herbs, probiotics, prebiotics and synbiotics, lactoferrin, and bacteriophages. It was found that the best results could be achieved through the use of pro-, pre- and synbiotics. However, the authors would like to point out that with the expansion of knowledge about the practical use of broad-scale bacteriophages, they could be the best alternative to antibiotics.

Published: January 2020

Advancements in information technology has given rise to a new flipped learning environment that is increasingly used at post-secondary institutions. This new pedagogical approach provides a personalized learning experience by accommodating different students’ learning styles. Students interact with the course material prior to attending scheduled face-to-face instruction, where learning is reinforced by working through examples and application problems. This paper provides a practical guiding framework for the collaboration and coordination of multiple instructors in a flipped delivery course style, based upon a literature review, qualitative research, and experience. We used a qualitative approach using a questionnaire to gather lessons learned and suggestions from instructors. The responses were analyzed to extract common themes which were mapped to create a conceptual framework for successful multi-instructor flipped course delivery. Recommendations are made as per three chronological sequences of before, during and after the course offering. The framework aims to support the planning, implementation and evaluation stages of organizing and managing a multi-instructor flipped course. This paper stresses the importance of the teaching team proactively completing the planning and design of course components before the start of the course. Quantitative student feedback received from the fall 2018 course offering in Schulich School of Engineering at the University of Calgary is used to support the flipped classroom delivery, multi-instructor delivery style.

Le génie a longtemps été un domaine d'études et de carrières réservé aux hommes [29]. Nous menons une étude pancanadienne auprès d’ingénieurEs et de futurEs ingénieurEs, sur leur conception du génie et l’importance qu'elles et ils accordent à la contribution des femmes au génie. Il s'agit d'une étude féministe inspirée du modèle de Cronin et Roger [7] qui consiste en des entrevues semi-structurées réalisées jusque-là auprès de 70 participantEs.

Selon ces participantEs, les femmes apportent des perspectives qui tendent à améliorer la condition humaine et seraient plus ancrées à travailler sur des questions d’intérêts féminins. L’étude permet ainsi de mettre en évidence les contributions uniques des femmes en génie à la valorisation de la recherche, aux innovations technologiques tout en encourageant une meilleure participation des femmes en génie.

En Amérique du Nord, le besoin d’une relève d’élèves qui souhaite poursuivre des carrières en STIM est criant [3, 38, 48]. Les gouvernements de plusieurs pays, incluant le Canada, ont donc réalisé l’importance de l’enseignement en STIM et il est devenu évident qu’il y a un manque de compréhension de ce dernier [29].

Afin de faire avancer l’enseignement du génie dans les cours de sciences et mathématiques, nous avons mené une auto-ethnographie sur notre expérience comme enseignante de sciences et de mathématiques au palier secondaire. Nous sommes fières d’avoir été capables d’engager des élèves d’une diversité de genres aux activités d’apprentissage en STIM. Pourtant, nos activités ont été concentrées sur les sciences, les technologies et les mathématiques plutôt que sur l’ingénierie; une pratique qui doit changer afin d’inciter plus d’élèves à se diriger dans cette profession [42].

Despite this, overall results suggest that exam wrappers lend themselves well to improving learning, both for the students and instructors in the context of engineering classrooms.
PEER TUTORING IN A PROJECT-BASED COURSE PART 2: THE SECOND YEAR OF IMPLEMENTATION - IMPROVEMENTS AND BENEFITS
Authors: Brousseau Jean , Sano-Gélinas Andrée , Méthot Jean-François
Published: January 2020

In Fall 2017, a peer-tutoring program (PTP) was implemented in a first-year multidisciplinary design course of the mechanical, electrical and electromechanical engineering programs at Université du Québec à Rimouski. Fourth-year students with relevant design experience acted as tutors for teams of first-year students. The intent was to reduce the pressure on our professional staff, while maintaining the quality of supervision.

PTP assessment revealed that all stakeholders appreciated the experience. At low cost, it allowed more weekly hours of supervision and freed up time for professional staff to perform tasks requiring their expertise. Although the impact of the PTP on the quality of learning was not directly measured, the student level of satisfaction was very high. However, the teaching team concluded from PTP assessment results that tutors could have more impact on teamwork and team spirit if they were better prepared. Four main areas for improvement of the PTP have been identified. Modifications for improvement of the PTP were developed as follows. Tutor training was modified to include content on teamwork, group dynamics and conflict resolution. To enhance communication between tutors and teaching team, tutors were provided with a new week-by-week guide outlining project planning and giving tutors instructions for structuring team discussions. Tutors participated in a professional co-development session in the fifth week of the project, an activity that allowed tutors to learn from each other and improve their practice. Lastly, the assessment questionnaire was improved to collect more significant data on student learning and teamwork.

The new assessment results reveal that the changes made to the PTP have had a very positive influence on teamwork and group dynamics. Results also indicate that the improved PTP has a positive impact on achievement of course objectives. In conclusion, peer tutoring is evidently a very good strategy for supporting first-year students in the development of their design skills.
DEPLOYING ENGINEERING CASES TO FACILITATE PROBLEM-BASED THINKING IN ENGINEERING COMMUNICATIONS
Authors: Lamont George , Lambert Stephan
Published: January 2020

First-year engineering students often struggle to communicate the value of their work because they do not understand how problem-based reasoning drives engineering research and industry. Recognizing the effectiveness of discipline-specific teaching of the conventions of engineering communications, researchers have recently suggested the value of teaching the Swales "CARS" model to help students contextualize and justify their work. In two sections of Communications for the Engineering Profession at the University of Waterloo, we incorporated teaching of the Swales model of problem-based reasoning to help students understand the conventions of engineering communications, but found that authentic engineering documents are often too complex for this purpose. To address this limitation, we deployed engineering cases in two electrical/computer engineering courses to exemplify this model, and used pre-teaching and post-teaching surveys to measure students' perceptions of improvement in their ability to understand problem-based reasoning and apply it to project conceptualization. The results show that using simplified engineering cases of this kind both improves students' ability to use this model and improves their confidence in doing so. This outcome has implications for increasingly popular engineering-communications courses because it demonstrates the value of using realistic but simplified engineering scenarios to teach the Swales model in authentic and effective engineering communication.

Student mental health and well-being are increasingly a focus of post-secondary institutions across Canada. Many academic institutions have opted to offer a fall reading week as a means of reducing student stress and improving their mental health. This paper presents a review of the academic research that has been done to study the impact of a fall reading week on students’ mental health and wellbeing. The paper also presents the status of the fall reading break in the top 30 Canadian Universities.

Based on the results of this research, the authors have developed a proposal of introducing a fall reading week at the University of British Columbia, Okanagan Campus (UBCO). The proposal has been accepted in concept by the Provost’s Office as well as by the Senate’s Academic Policy Committee for possible implementation.
CAD / ARDUINO INTRODUCTORY WORKSHOPS IN FIRST YEAR ENGINEERING PROJECT-BASED COURSE A WAY TO GET STUDENTS TO DESIGN AND BUILD HIGH QUALITY PROTOTYPES
Authors: Méthot Jean-François , Brousseau Jean
Published: January 2020

As educators, there are several challenges that we need to overcome during the first-year of our engineering programs. We need to integrate students into the world of engineering and introduce them on practical aspects. We have to connect them with basic notions in various engineering fields and complementary disciplines. We have to start developing their design skills and make them able to conduct design projects despite an undeveloped level of knowledge. We want to make them able to design and build high-quality prototypes.

At UQAR, the solution goes through a multi-disciplinary project-based course offered at the first term. This course brings together students from mechanical, electrical and electromechanical engineering programs which makes possible to form teams of students with varied skills from different backgrounds (technical and natural sciences).

In 2018, the proposed project was the production of a stand-alone and collaborative mobile platform. This platform or robot receives an order for an item, picks up and transports a shelf to the deposit station, delivers the item, returns the shelf to its place and returns to the starting position, all while avoiding obstacles on the way.

To fulfill such an ambitious mandate, basic notions of CAD, electronics and programming are needed. Our innovation is the introduction of workshops at the beginning of the term. Workshops are an important part of our recipe to enable students to overcome the design challenge.

The mechanical workshops include four sessions related to mechanical CAD (modelling, sheet metal, assembly and drawing) and 3D printing.

Arduino workshops include three sessions on how to use the Arduino IDE programming environment and incorporate some programming notions. Specialized material was produced concerning the introduction to microcontrollers and the Arduino platform. A set of specialized parts was provided to the students. Several demonstration examples and activities have been produced on digital inputs and outputs, analog inputs, pulse width modulation outputs, ultrasonic distance sensing, DC motors and H-bridges, servomotors, tracking sensors lines, wireless communication modules, mini-keyboards and LCDs.

The workshops support the projects directly and allow students to carry out relatively complex projects in the first year despite their limited engineering knowledge.

Setelah dilakukan metode rank positional weight, stasiun kerja yang dimiliki saat ini berjumlah 8 berkurang menjadi 6 stasiun dengan mengurangi 2 stasiun terakhir dan didapat peningkatan efisiensi rata-rata stasiun kerja sebesar 19%.
Integration of Divine Impassibility with the Theopaschite Formulas in Early Christianity
Authors: Streltsov A. M.
Published: January 2020

This article deals with a variety of opinions concerning impassibility of God in the early Christian thought of the first three centuries. Along with obvious similarities of this concept with the stance of the ancient philosophical theology certain differences also present themselves, the most obvious of which marks the presence of theopaschite formulas due to the doctrine of Incarnation. The viewpoints stretch from the rigid insistence on impassibility (Apologists, Clement of Alexandria) to a more flexible approach of Origen and, finally, to the statement that it is possible to speak of the divine suffering in some sense (Gregory Thaumaturgus). With no unified terminology worked out, Patristics of this period, nevertheless, managed to lay an appropriate framework enabling the development of metaphysics of «impassible suffering» of God in subsequent Christian philosophy.
