City College

The Grove City College (GCC) European Study Center (ESC) is a program that allows mechanical and electrical engineering students to study abroad in the junior and senior year fall semester, respectively, and graduate in four years. The ESC is activity partners with a local institution called Oniris, which specializes in food science engineering, and veterinary science (an affiliate with the French Ministry of Agriculture). Electrical engineering students that participate in the program carry out their yearlong capstone design project (Senior Experience in Electrical Design (SEED)) in partnership with Oniris. For the 2016–2017 academic year, participating electrical engineering students completed a project titled Ultra-Low-Cost Flexible Sensor Array, or “Low-Cost Array” (LCA), designed for commercial tunnel-style ovens. The LCA features low cost ($200), flexible programmability, and ease of use (based on the widely available Arduino). The purpose of the project was to develop a low-cost data-logger to operate inside tunnel-style ovens to record temperature from thermocouples (and other analog signals, i.e. heat flux) for thirty minutes in an environment up to 250 °C. This study evaluates the LCA compared to other data-logging systems, and its performance in high temperature environments by a series of experiments. In addition, an idea of its commercialization potential was explored by interviewing industrialists and academics on-site. Experimental results showed that: (1) data logged from the system were close to values recorded by current systems used for both temperature and heat flux measurements, and (2) the system performed well at 240 °C for thirty minutes (maximum temperature of oven). In addition, the interviews revealed that although most interest was in a tunnel-style oven data-logger, it seems feasible to incorporate changes to satisfy needs for other markets, especially those of a general-purpose data-logger.

As engineering skills becomes a commodity, electrical engineers’ programs are urged to adapt their pedagogical strategies do better prepared their graduates. The 21st century engineers are expected to have a strong technical background while being capable to work with people with different kinds of intellectual and social capitals, and to have a high level of cognitive flexibility. This article reports on the application of an information appropriation method, adopted by the Department of Electrical Engineering at PUC-Campinas, where activities on extension projects are simultaneously conducted along with the regularly schedule classes. The study case is related to the coplanning and cocreation of a technological white cane (proof of connect) between electrical engineering students, social technicians and the visually impaired. In the present case, the technicians were led to reinterpret, adapt and reinvent technology while contributing to the design and build of a low cost adaptive electronic sensing aid attachable to a white cane. The collaborative method, applied during conversation rounds, is based on a virtuous cyclic process which includes steps like information capture, validation, guidance and feedback. The engineering students, on the other hand, have the opportunity to develop their communication, analysis and interpretation skills in a way not available in the classroom. They also experience solving conflict situations and find creative uses and applications for they knowledge not otherwise foreseen. The participating students transformed information into knowledge through a dialogical experience with people having a contrasting technological background to its own. Through this experience the engineering graduates emerged with a greater sense of responsibility with the society and a better understanding of what means to be an engineer. Participation in the Extension Project also brought up several opportunities of professional recognition by the technicians and the visual impaired themselves, which stimulated the students do achieve better performance in the course.

Multi Method Approach

Engineering education researcher Rogers (2006) proposed that an assessment of engineering programs should use a multi-method approach to maximize validity and reduce the biasness of any one approach. Based on this reason, this study used two methods in the direct assessment of oral communication skills performance outcome of an undergraduate electrical engineering students’ Final Year Project (FYP) design experience. In the first method, the Oral Communication Assessment Rubrics adapted from Norback et al. (2008) was tested for its reliability, consistency in the scores and ease of use. This was to ensure that the results were descriptive of the expected students’ performance (Miller & Olds, 1999). Once faculty rater reliability was achieved and verified, the rubrics were refined and redrafted to obtain inter-rater scores for the assessment of the oral communication skills during the FYPII seminar presentation. Descriptive statistics were used to draw inferences from the inter-rater scores. In the second method, the researcher used the final grades of these students which were obtained from the faculty end-of-course assessment of their FYPII seminar presentation through the use of the faculty Seminar Evaluation Form (SEF). The scores obtained from SEF were reported in the Course Assessment Summary Report (CASR) in the form of the achieved Key Performance Indicator (KPI) of the students in each department in the Electrical Engineering Faculty (FKE).

Waste Stabilization

Abstract Although waste stabilization ponds (WSPs) are widely used in developing countries, monitoring data on their operational performance are scarce. Traditional methods for monitoring in-pond conditions, i.e. conducting hand held measurements from a small boat or installing fixed sensor networks, are not straightforward to realize and create an unhealthy working environment for field workers. A promising technology for the safe and efficient collection of monitoring data is a compact autonomous surface vehicle (ASV), capable of autonomous navigation along a predefined trajectory based on geographic coordinates and measurements in different places and depths. In this practical paper, the development process, technical details and functional testing results of a low-cost ASV for WSP monitoring are presented. Commonly available construction materials and electronic components were used to ensure affordability and reparability. The access to online tutorials and peer-support was crucial for assembling the open-source autopilot and data logger. The ASV demonstrated satisfactory performance for both the autonomous navigation as well as the georeferenced data logging of measurements at a real-scale WSP in Paraguay. This study demonstrates how the adoption of open-source hardware and software offers the flexibility for the wastewater professionals to develop customized DIY solutions for specific monitoring applications and working environments.

Development And Validation

Insufficient access to safe drinking water is one of the most challenging global humanitarian issues. The development of low-cost microcontrollers and the widespread availability of cheap electronics components raise the possibility of developing and using low-cost geophysical instrumentation with open-source designs and software solutions to circumvent geophysical instrumentation capital cost issues. To these ends, we alter an existing low-cost DC resistivity meter design and develop an optional modular Raspberry Pi data-logging system to improve the unit's functionality, usability and to ensure data integrity. Numerical modeling and physical testing demonstrates that the system is more robust than previously published low-cost designs and works in a more diverse range of geological scenarios - especially conductive environments. Our instrument was tested in a Geoscientists Without Borders (GWB) project jointly run between researchers from Colorado School of Mines (CSM) and Universit矤'Abomey-Calavi (UAC), Cotonou, Benin. A key project component involved CSM and UAC students constructing and validating two low-cost DC resistivity meters and then using these instruments for fieldwork aimed at better characterizing and monitoring the health of a local aquifer used as a groundwater source for communities in the Cotonou region. The low-cost instruments were successfully used alongside a commercial resistivity meter to acquire data for 2D inversion of aquifer hydrostratigraphy , indicating the presence of a clay-sand contact. The cost of the redesigned instrument and data logger respectively are $177 and $108 (in 2021 USD) with future cost reductions possible, which are fractions of the price of commercial resistivity meters.

A low-cost data logging platform is presented for environmental monitoring projects that provides long-term operation in remote or submerged environments. Three premade “breakout boards” from the open-source Arduino ecosystem are assembled into the core of the platform. The components are selected based on low-cost and ready availability, making the loggers easy to build and modify without specialized tools, or a significant background in electronics. Power optimization techniques are explained. The platform has proven to be highly reliable, and capable of operating for more than a year on standard AA batteries. The flexibility of the system is illustrated with two ongoing field studies recording drip rates in a cave, and water flow in a flooded cave system.

Electrical parameters such as voltage, current, power, energy, frequency, and power factor are parameters needed in the operation of an electrical system and machinery. The measurement results provide an overview of the system performance and indicator of abnormal or faulty operations. Nowadays, the electrical parameter instruments grow rapidly with a wide range of features and capability, started from analog instruments to digital measurement with data logging features. This paper reviews the availability of electrical parameter instruments and data logger systems in Indonesia. The review includes technical specifications of instruments, manufacturers, vendors, and data logging features. The data were obtained from vendor publications, manufacturers, scientific publications, and e-commerce websites in Indonesia. The information regarding the availability of the instruments and data logger systems will provide a quick reference in choosing instruments for a certain application to suit the purpose of the measurement and also the cost of the device. Moreover, the information also can provide benchmarks for research and development of low-cost multichannel data logging systems with additional features such as remotely accessible through the implementation of the internet of things.

<p>Each solar thermal plant can provide different parameters to be treated and evaluated, mostly temperature measurements, pressure specifications, heat transfer values. This data collection can be quite expensive taking into account the important number of sensors and data loggers and their specifications. Hence to assure flexibility in the data collection at a low cost, many hardware and software specifications can be adopted. Here we built an inexpensive data logger based on the Arduino board and IDE to collect and store incoming data from Resol DeltaSol regulators integrated in different solar water heating systems. The objective of this study is to allow massive synchronized measurements with high resolution to be stored into an SD card through the Arduino platform. The measurements are given by multiple sensors (temperature, pump speed, relay states) connected to the regulator. The results from the tests of the plant connected to the data logger are provided later on, alongside the commercial aspects of the built data logging device. After a month of daily measurements, the data logger showed an outstanding performance with an extreme low cost compared to industrial datalogger. </p>
