Examining indicators for effective studying – The interplay between student integration, psychological flexibility and self-regulation in learning
Authors: Asikainen Henna
Published: June 2018

Prolonged study times and dropouts from university studies have created a need to examine more ways to support students’ studying. This study aims to examine the relationship between the self-regulated learning, psychological flexibility and student integration comprising teacher and student interaction, students’ commitment to studying as well as the relationship of these aspects to study progression. The participants of this study were 117 theology students. Items measuring student integration were first analysed with factor analysis. The relationship between student integration, psychological flexibility, self-regulated learning and study progression was analysed with correlation analyses and Structural Equation Modelling (SEM). The results show that psychological flexibility is related to study progression, self-regulated learning and student integration. The effect of self-regulated learning and student integration to study progression was not significant. This study suggests that students’ way of coping with negative thoughts and emotions should be taken into account when considering learning and teaching.

Modularization of New Courses in a Curriculum – Proposal for an Advanced Fluid Power Course
Authors: Rodriguez Jorge , Choudhury Alamgir
Published: June 2018

Most programs and curricula being offered nowadays is packed with courses and required activities, thus leaving very few options whenever a new course with additional concepts or materials is being included in an existing plan of study. Typically the option is to exclude some existing course in order to make room for the new one, thus avoiding the increase in total credit requirements in the program. Fluid power is a field that has gone through a cycle of being a staple in many technical programs because of its wide use in industry as primary option for power transmission; then having a substantial drop in its study and applicability; and then becoming once again a preferred power transmission alternative. Hydraulic fluid power is a mature technology, and new applications present several new challenges, with significant benefits. Therefore, there is a growing need to have fluid power education in many engineering and engineering technology curricula. Curricular development has been planned in order to offer advanced fluid power technology education in existing programs. This development has the main characteristic that is modularized, thus presenting the opportunity to be included in existing programs without the need for new courses. The modules are not introductory levell, and the development will have the overall context of systems integration, with topics on controls, mobile, and energy efficiency. In this development the learning outcomes have been established, and at this point the input from industrial constituents is being requested in order to establish specific content, and how the modules should be developed and integrated. This paper includes the information used to define the topics, and the actual content in the proposed modules. It is expected that this development will address the limited exposure to fluid power that students of engineering and engineering technology programs face, have, thus allowing them to consider careers in such industry.

Di (2-ethylhexyl) phthalate (DEHP) is a plasticizer used in the polyvinyl chloride (PVC) industry. The indiscriminate use of various products manufactured with PVC, causes this plasticizer to be considered a contaminant. Fusarium culmorum is a phytopathogenic fungus that has the ability to produce esterase enzymes. Esterases are of great importance because they can break the ester bonds present in the plasticizers. In this work, the activity of esterases produced by F. culmorum grown in media supplemented with different concentrations of DEHP (1500 and 2000 mg/L) in solid-state fermentation and submerged
fermentation was characterized by biochemical tests and polyacrylamide gel electrophoresis. F. culmorum showed higher esterase activity in media supplemented with 1500 and 2000 mg DEHP/L in solid-state fermentation. A greater number of esterase activity bands were observed in the DEHP-supplemented media, having a molecular weight of about 20, 25, 37, 45, 55, 75 and 150 kDa, in both fermentation systems. 1500 mg of DEHP/L induced a higher production of esterases, demonstrating that high concentrations of DEHP did not inhibit the enzymatic production of the fungus.

Performance Measurement System (PSM) and Balanced Scorecard (BSC) Strategies Used in the Process related with Ramp Handling Services of Ground Handling Management
Authors: İnan Tüzün Tolga
Published: June 2018

In civil aviation
sector, the design of airports is divided into two as air side and ground side.
The latter part of second security gate in terminal building at the airports is
defined as air side in the literature (which is defined as customs area). The
air side is also divided into; ground service and airspace. In this research,
the concept of ramp services which constitutes basic content of ground service
management process is examined. One of the two most important causes of delays
in civil air traffic is that ramp services can not be planned effectively (the
other reason is that airport capacity is extremely dense), so this concept
needs to be well analyzed and evaluated. The performance measurement system
(PMS) and balanced scorecard (BSC) methods in this review are examined in terms
of the conceptual background within design, measurement and implementation phases
for effective ramp services process in ground handling management.
Development of Crew Resource Management Concept in Civil Aviation

Published: June 2018

The fact that 60% of
mortal accidents made by scheduled passenger transports in civil aviation
sector are human error initiated and more than 70% is direct cause of human
error is reported in past analysis. However, human error can not be reduced to
zero. Because human nature has potential to make mistakes in every condition
and/or situation, especially stress status. For this reason, it is impossible
to reduce the error margin to zero in human factor and also minimizing
constitutes main theme in this research. The concept of cockpit/crew resource
management (CRM) in civil aviation was first introduced by National Aeronautics
and Space Administration (NASA) in 1979 with aim of improving flight safety by
regulating communication principles between flight crews at the beginning.
Today, the concept has been further developed and a significant part of civil
aviation trainings. In this research, the concept of CRM is divided into five
generations under the name of cockpit and cabin resource management. The
concept of CRM, which has been exposed to great criticism in previous
generations has become a concept that needs to be included in the curriculum of
staff trainings. Especially flight crews in all airlines, the concept of CRM
has become more and more relevant with the analysis of error management in
fifth generation more deeply.
Legal and Ethical Issues of Unmanned Aerial Vehicles
Authors: ÇOBAN Sezer , OKTAY Tuğrul
Published: June 2018

Unmanned aerial vehicles
(UAVs) are air vehicles that can fly remotely or autonomously fly over a
certain flight route by themselves. "Unmanned aerial vehicles", which
were first produced as military vehicles and then started to be used by
civilians, nowadays can easily be bought by everyone. Unmanned aerial vehicles,
which can be purchased and made accessible by all, have brought legal disputes
and legal regulations together with these disputes. Abuse is obvious because
there is a legal vacuum in the field of unmanned aerial vehicles. Of course, it
is important for Turkey to work integratedly with the fourth industrial
revolution. It is necessary to work like a lucky artificial intelligence,
intelligent systems without ignoring the most precious being.

In this study, the development
process of unmanned aerial vehicles will be examined in terms of the
availability of unmanned civil aircraft in air vehicles, the use and flight
conditions, the availability of law in the technological development of
unmanned aerial vehicles, and the ethical problem of the production and use of
these vehicles.

The rubric became a guide for students in determining the criteria and performance measurement scale oral presentation of his colleagues. Statistical tests performed with Second Order Confirmatory Factor Analysis (CFA) Order using the Smart PLS 3.0. This instrument was built based on three dimensions of oral presentation: content, delivery, and collaboration. As a result, all three of it were found to be statistically valid and reliable, meeting the criteria so that it can be used for peer assessment of oral presentation.
Multiple Arabic Equivalents to English Medical Terms
Authors: Al-Jarf Reima Saado
Published: June 2018

Translation of medical texts poses several challenges to undergraduate student-translators due to multiple Arabic equivalents to English medical terms. For medical terms such as clinical, intensive care, polyp, and osteoporosis several Arabic equivalents exist. A sample of English medical terms with multiple Arabic equivalents was collected from several English-Arabic medical dictionaries to find out the types of multiple Arabic equivalents given, the shortcomings of Arabic equivalents, and the difficulties that students have with multiple Arabic equivalents. Two lists of categories with definitions and examples were developed and used in classifying and evaluating the equivalents. In addition, students answered an Arabic medical terminology test and responded to a questionnaire-survey to find out their difficulties. Results of the analysis and evaluation of the Arabic equivalents, medical terminology test, and responses to the questionnaire-survey are reported in detail. Recommendations for translation instruction are also given.
The Absence of Longer Texts in Literature Classes in Some Open and Distance Education Courses in India: Learning Outcomes
Authors: Arnab Chatterjee
Published: June 2018

Self-Instructional Materials (SIMs) in distance and open learning (ODL), particularly in case of literature modules in certain open universities in India do not seem to provide the longer texts of works penned by both canonical as well as non-canonical authors; short poetry and critical pieces are just some of the exceptions. Often the emphasis is on the critical material available on the author, coupled with notes and commentaries. As any understanding of a text is important to gain a deeper understanding of the socio-economic and the cultural milieu in which the work was conceived, while “reading between the lines” can be of additional help, often this absence raises questions as regards the efficiency of the SIMs used in the literature classroom. On the other hand, regular courses in the nation emphasize the reading of the text per se. This paper would like to analyze the learning outcomes of around fifty students in the ODL mode and around the same number of students in a literature class in “regular” mode using the theories of learning and behavioral conditioning in psychology and analyze this issue of availability and non-availability of texts in a classroom, particularly in a literature course from the vantage point of student responses and subsequent evaluation in exams.

GIS-Based Rainfall Estimator Evaluation and Interpolation Analysis Using ArcGIS
Authors: Mambu Joe Yuan
Published: June 2018

We have been always trying to predict the weather to minimize risk, produce strategy, and other decision making situation. To achieve this, monitoring method need to be used to gather data. Rainfall monitoring is one of the area that widely used and one of the mostly used method is satellite-based rainfall monitoring. However, there are limitation to apply to the Satellite Rainfall (SR) estimation specifically on its accuracy and lack of certainty. Thus, study that directed to measure the inaccuracies of SR measurements is needed by using data of distribution of Actual Rainfall (AR). The SR data is taken from the National Oceanic and Atmospheric Administration (NOAA)’s Hydro—Estimator while the AR data was from the National Institute of Water and Atmospheric Research (NIWA). Through the statistics and interpolation analysis using ArcGIS, the study shows a prominent result of SR estimation accuracy in the sample area and thus may opens up more similar implementation as well as stands as a good benchmark for future improvement of the method. This study also shows how interpolation method through a GIS software could provide a significant result on a geographical related studies. Keywords : GIS, Geospatial Analysis, Interpolation Analysis, Arcgis

Most of the major micro hydro power plants in Nepal uses Crossflow turbine for power generation which are manufactured locally. However, efficiency of these turbines has not been tested and verified. In this research, Cross flow turbine designs were obtained from local manufacturers. Efficiencies of these turbines were determined using simulation under steady state condition. Efficiencies were verified using the data from the installation site where these designs were used. Different Cross flow turbine models were prepared by varying the curvature radius of the blade and the ratio of inner to outer radius of the runner. The efficiencies of such models were determined using simulation.Journal of the Institute of Engineering, 2017, 13(1): 1-9

Published: June 2018

An earthquake of moment magnitude (Mw ) 7.8 struck the central Nepal at 11:56 am on April 25, 2015. More than 9,000 people were killed and thousands of residential buildings, and hundreds other structures were also destroyed. An aftershock of moment magnitude (Mw ) 7.3 hit northeast of Kathmandu on May 12 after 17 days of main shock which caused additional damages. Immediately after the earthquake, authors undertook a field investigation and visited the affected areas. Strong motion records from both earthquakes and their impacts on structures as well as geotechnical issues are presented in this paper. Most of the structures in Nepal are made of adobe, unreinforced masonry, and reinforced concrete. Failure mechanisms of those buildings are briefly explained in this paper. Geotechnical aspects such as soil liquefaction, slope failures, settlement and lateral spreading, and site amplification effects that considerably influenced the damage patterns at many areas are briefly discussed as well. The lessons learnt from this earthquake are also summarized in this paper.Journal of the Institute of Engineering, 2017, 13(1): 20-36

Authors: Dawadi Babu Ram , Baral Daya Sagar
Published: June 2018

Institute of Engineering (IOE), Tribhuvan University (TU) is the government owned oldest institution in Nepal providing quality education in the engineering domain since 1972. However in the recent decade, other several universities are established in the country, IOE hasn’t lost its popularity with its major features to have dedication on quality education to fulfill the world class education. As a public institution, it provides equal opportunities for all qualified citizens to enter into the university education. With the increasing number of affiliated colleges and applicants, the entrance exam and admission system are becoming challenging. Accepting the challenges, IOE adapted online applications and admit card generation with computer based entrance exam since 2014. Since recent past years, the student pass rate in the semester exams is not satisfactory. It raised the quality issues and required to find the causes so as to enhance quality. However there are several factors that affect the education quality, we identified that the admission process followed in most of the affiliated colleges is partially in the meritorious basis that affects the semester exam results. From this paper, we analyzed the past admission process and the student’s status in semester exam where we tried to co-relate the quality intake in entrance exam and the semester exam of IOE. We proposed an optimal technical framework to admit merit based applicants through online centralized admission system that helps to overcome the admission challenges and enhance the quality of engineering education of IOE.Journal of the Institute of Engineering, 2017, 13(1): 48-59

Authors: Adhikari Basanta Raj , Nidal Naresh , Yadav Bhupendra Kumar , Awasthi Surendra
Published: June 2018

Abstract: Nepal Himalaya is one of the most active mountain belts with several kilometers of relief which is very prone to catastrophic mass failure and this region encounter the problem of landslide almost every year during monsoon period causing large scale of devastation. Most of the landslides are caused by river bank erosion, monsoon and earthquakes. Patlekhet landslide, Myagdi district represents the vulnerable condition of the hilly region and therefore it is chosen for study. Hydro-meteorological analysis of the landslide including estimation of the physical characteristics of the landslide and different parameter were used for the study. The Thiessen polygon and arithmetic average methods are used for rainfall analysis of the landslide and high flood level is estimated at the toe of the landslide. The risk is calculated by assessing the vulnerability of different exposure elements such as population, households, agricultural land and water supply through the use of quantitative tools and techniques. It is clear that the landslide was triggered by heavy rainfall and toe cutting by Raghu Ghat Khola. Around fourteen percent households’ lie in the high risk zone and others are in moderate and low risk zone. The level of risk is changing every year with increasing number of population and continuous movement of landslide.Journal of the Institute of Engineering, 2017, 13(1): 78-89

Published: June 2018

Abstract: Because of increasing number of natural and human created disasters worldwide, a research on challenging issues of emergency management are being quite emerging for the betterment of today's complex real-life. The diversified operational research models and their solutions techniques together with their simulation schemes are yet not evident in realizing a generally acceptable solution of these challenging issues. We consider the planning problems in emergencies which is even unsolved yet in general. In this paper, we briefly give the models and algorithms on the existing solution approaches within the framework of evacuation planning network flow models, where the objectives are either to maximize the flow over time or minimize the time for transshipment of the estimated flow. The flow models and solution techniques with their insights presented here highlight the state of existing approaches and hint further direction of research in the field of evacuation optimization. Journal of the Institute of Engineering, 2017, 13(1): 90-101

Efficient Solution Approach to Maximum Flow Evacuation Planning Problem without Flow Conservation Aspect
Authors: Bhandari Phanindra Prasad , Khadka Shree Ram
Published: June 2018

An attempt of shifting as more people as possible and/or their logistics from a dangerous place to a safer place is an evacuation planning problem. Such problems modeled on network have been extensively studied and the various efficient solution procedures have been established. The solution strategies for these problems are based on source-sink path augmentation and the flow function satisfies the flow conservation at each intermediate node. Besides this, the network flow problem in which flow may not be conserved at node necessarily could also be used to model the evacuation planning problem. This paper proposes a model for maximum flow evacuation planning problem on a single-source-single-sink static network with integral arc capacities with holding capability of evacuees in the temporary shelter at intermediate nodes and extends the model into the dynamic case. Journal of the Institute of Engineering, 2017, 13(1): 108-116
Analysis of One Bay Residential Building with Combined RCC Frame and Load Bearing Wall Structures
Authors: Maharjan Rajib , Shrestha Vivek
Published: June 2018

The major purpose of this study is to justify construction method of a hybrid structure in core area with construction complexity due unsafe excavation conditions and tries to define its rigidity and strength. Both RCC and Frame structure transfer same load to ground through foundation but the transfer mechanism varies. In some practical condition, building construction should be carried out in compact areas with unsafe adjoining building where adequate excavation for foundation cannot be carried out. In such cases, one bay hybrid structure is proposed for construction with combined RCC frame structure and load bearing walls. In these combined cases, both structures works as same unit to transfer building load but the transfer pattern varies. The variable load transfer pattern is due to discontinuity in structural system which also effect on seismic response of the building. The placement of a masonry load bearing structure in RCC frame structure varies design of all structural components of the building. To study actual behavior of hybrid structure in various load condition and introducing cost minimization techniques of buildings structural analysis was carried using ETABS 2016 with composite structural arrangement and with induction of load bearing wall as structural component. By which seismic behavior of building in both cases was obtained as well as reduction in rebar percentage and dimensional reduction of structural components can be achieved.Journal of the Institute of Engineering, 2017, 13(1): 117-124

Authors: Sharma Niranjan Prasad
Published: June 2018

The study is based on the variations of aerosol optical depth in Bhaktapur, Nepal. Microtops II Sunphotometer, manufactured by solar light inc. USA was used to measure the Aerosol optical depth. The diurnal variations of Aerosol Optical Depth (AOD) in January, 9 at 2.32UT were found to be 1.01, 0.89, 0.81 and 0.61 at 340,440, 500 and 675nm respectively. Besides ozone and clouds, aerosol plays an influencing role to attenuate solar UV radiation reaching the ground. Spectral dependence of AOD possesses higher values at shorter wavelengths and gradually decreases towards longer wavelengths in all seasons. The value of wavelength exponent (α) and aerosols concentration (β) on June 15 and July 25 at Kaushaltar were found to be 0.80, 0.56 and 0.45, 0.57 respectively.Journal of the Institute of Engineering, 2017, 13(1): 133-138

Authors: Shrestha Rajeshwar Man
Published: June 2018

The adsorption of Iodine by the activated carbons prepared from a locally available material Lapsi Seed Stone has been studied. Various activated carbons were prepared by varying the parameters such as ratio of Lapsi Seed Stone particles to Phosphoric acid, percentage of phosphoric acid concentration, carbonization temperature and carbonization time. Determination of Iodine numbers of the activated carbons was done by the standard method. The effect of various preparation conditions on Iodine number of different activated carbons is also investigated. The optimum conditions for the preparation of activated carbon are found to be 400 ° C -the carbonization temperature, 4 hours - the carbonization time, 1:1- the ratio of Lapsi Seed Stone particles and Phosphoric acid and 50 %- the percentage of phosphoric acid concentration.Journal of the Institute of Engineering, 2017, 13(1): 139-144

Comparative Study on the Adsorption Capacity of Activated Carbon Prepared from Lapsi Seed Stone and Betel nut using Phosphoric Acid
Authors: Joshi Sahira
Published: June 2018

This paper presents the comparative study on the adsorption capacity of activated carbons prepared from Lapsi (Choerospondias axillaris) seed stone and Betel (Areca catechu) nut. Activated carbons (ACs) were prepared from Lapsi seed stone (LSS) and Betel Nut (BN) by chemical activation with H3PO4 (in the ratio of 1:1 by weight) at 400°C. The pore structure of activated carbons was determined by iodine number and methylene blue number. Surface morphology of ACs was studied by scanning electron microscopy (SEM). Surface functional groups were analyzed by Fourier Transform Infra Red Spectroscopy (FTIR). As indicated by TGA analysis, the appropriate temperature required for carbonization was 400 ºC. Betel nut AC showed high iodine number and methylene number of 888 mg/gm and 369 mg/gm respectively. SEM micrographs of Betel nut AC show the presence of well developed pores on its surface. FTIR result indicated that both ACs contain −OH, >C=O groups as oxygen containing surface functional groups. Based on the result, the AC prepared from betel nut by activation with H3PO4 is comparable with commercial activated carbon and could be used as potential adsorbent for removal of pollutants from water and waste water.Journal of the Institute of Engineering, 2017, 13(1): 153-159

Authors: Rana Nandalal , Bhandari Krishna P , Shrestha Surendra
Published: June 2018

Bandwidth requirement prediction is an important part of network design and service planning. The natural way of predicting bandwidth requirement for existing network is to analyze the past trends and apply appropriate mathematical model to predict for the future. For this research, the historical usage data of FWDR network nodes of Nepal Telecom is subject to univariate linear time series ARIMA model after logit transformation to predict future bandwidth requirement. The predicted data is compared to the real data obtained from the same network and the predicted data has been found to be within 10% MAPE. This model reduces the MAPE by 11.71% and 15.42% respectively as compared to the non-logit transformed ARIMA model at 99% CI. The results imply that the logit transformed ARIMA model has better performance compared to non-logit-transformed ARIMA model. For more accurate and longer term predictions, larger dataset can be taken along with season adjustments and consideration of long term variations.Journal of the Institute of Engineering, 2017, 13(1): 160-168

Published: June 2018

There are several third order numerical methods having same efficiency index appeared in literature for solving nonlinear equations of a single variable. Practically, if we apply these methods in different nonlinear equations, we can observe that all methods are not performed equally for given nonlinear equations. The main objective of this paper is to show through numerical experiment that the performance of some third order methods having the same efficiency index does not perform equally for particular nonlinear equation. For the numerical comparison, we use Matlab software.2010 AMS Subject Classification: 65H05 Journal of the Institute of Engineering, 2017, 13(1): 169-174
