Abstract:
Objective. Evaluate the General Physics courses (theory and laboratory) of the Science Teaching career with the university teaching staff, in the period from 2014 to 2019, to identify the strengths and weaknesses in the methodology and propose new educational strategies. Method. The research was conducted through a virtual survey with the LimeSurvey software to the teachers who have taught Physics courses for the Science Teaching career in the last five years; the survey was applied to the total population of 20 teachers, but only 12 of them answered it. The instrument was designed by the teaching staff working on the project to improve the laboratory manuals. The instrument analysis was carried out with the help of an Excel spreadsheet provided by the LimeSurvey software. The instrument was validated by IDESPO staff of the National University regarding the relevance of the content of the statements, the clarity of the questions, and the coherence with the objective of this study. Results. The structure and organization of the General Physics courses have a positive assessment by the teachers, who also showed a preference for the traditional lecturing; but even so, they are willing to train and learn new teaching strategies. Conclusions. The results of this investigation show that teachers are open to technological change and to working on the challenges that government policies have proposed.

Abstract:
This study aims to conduct a field study on the need to develop Augmented Reality (AR) assisted practicum guidelines. Data collection instruments were in the form of questionnaires and interview guidelines. The subjects in this field study were students who became practicum assistants, physics laboratory staff, and lecturers of basic physics courses. Questionnaire data and interview results were analyzed qualitatively to see the real conditions of the practicum. Based on the results of data analysis, it is known that practicum manuals are still dominant in text, and practicum activities can be directed to practice problem-solving skills. The phenomenon of coastal areas can also be associated with physics practicum material. Based on the results of the practicum assistant's questionnaire, it is known that AR can facilitate physics practicum, so it is necessary to develop an AR-assisted practicum guide that presents audio-visual presentations. Based on the results of the interviews, it is also known that the constraints on practicum activities during this pandemic were that not all practicum courses were available at PheT to carry out virtual practicums, counter-dependence with assistant explanations in carrying out practicum procedures, so strict procedures could not be carried out, so it could be interpreted that a solution was needed an alternative practicum guide that is equipped with a video tutorial about practicum procedures. AR technology can be used to visualize tutorial videos that can be accessed offline.

Abstract:
Abstract Robert Millikan’s experiment, conducted in 1909, aimed to measure the charge of the electron. This experiment holds immense significance in the fields of electricity and magnetism and is widely performed by physics and chemistry students worldwide. While there are simplified two-dimensional recreations of this experiment available, obtaining measurements that closely resemble reality through a three-dimensional recreation is not easily accessible. This article delves into the development process of this three-dimensional recreation, achieved through reverse engineering of the original experiment using the Unity video game engine. Additionally, it incorporates laboratory equipment, user manuals, and a student guide to ensure a comprehensive experience. By comparing the data obtained from the virtual recreation with that of the real experiment, it was observed that the precision of the virtual experiment resulted in a mere 7% error. Consequently, the virtual experiment can be used as a substitute for the real experiment when circumstances prevent its execution, without compromising the hands-on experience.

Abstract:
In this paper, we designed from scratch, realized, and characterized a six-channel EEG wearable headband for the measurement of stress-related brain activity during driving. The headband transmits data over WiFi to a laptop, and the rechargeable battery life is 10 h of continuous transmission. The characterization manifested a measurement error of 6 μV in reading EEG channels, and the bandwidth was in the range [0.8, 44] Hz, while the resolution was 50 nV exploiting the oversampling technique. Thanks to the full metrological characterization presented in this paper, we provide important information regarding the accuracy of the sensor because, in the literature, commercial EEG sensors are used even if their accuracy is not provided in the manuals. We set up an experiment using the driving simulator available in our laboratory at the University of Udine; the experiment involved ten volunteers who had to drive in three scenarios: manual, autonomous vehicle with a “gentle” approach, and autonomous vehicle with an “aggressive” approach. The aim of the experiment was to assess how autonomous driving algorithms impact EEG brain activity. To our knowledge, this is the first study to compare different autonomous driving algorithms in terms of drivers’ acceptability by means of EEG signals. The obtained results demonstrated that the estimated power of beta waves (related to stress) is higher in the manual with respect to autonomous driving algorithms, either “gentle” or “aggressive”.

Abstract:
Education is the foundation of our society. The most important investment we can make collectively and individually is in education. Rural education is of utmost importance to enhance and develop the livelihood of rural people indirectly. But the face of education in rural parts of the country has to be considered for a serious check-up with children failing to receive a good quality of education. This is one of the reasons to drivestudents away from attending their schools. The education system in rural areas is information based rather than a practical oriented, which is a major setback for the economic growth of the nation. The prominent crises that hold back rural schools are the lack of smart learning technology and no proper access to laboratory equipment for the students. Augmented Reality (AR) is one of the finest technologies that can be utilized for education development as it amplifies the learning process.Marker-based AR android application can help by over-laying audio-visuals, computer graphics, 3-D graphical models’ representation, the contextual information of concept’s procedures, processes, working, functions and its usage directly over the manuals which make the subject more understandable and comprehensive, thus enhances the student’s knowledge. The utilization of AR technology in the field of education will prove to be a great positive societal impact essentially for rural school students. It sets a path for learning all the concepts smartly and efficiently. AR-based learning can create an impact because there is no need for the internet. The mobile application also helps to improve the student’s self-learning skills. In this paper, some concepts from biology and physics are considered, the graphical models, functionality and working are displayed in AR with the help of Maya 3D, Unity 3D.

Abstract:
AbstractIn recent years, the number of industrial exoskeletons has significantly increased. As a large share of assembly tasks still requires the execution of manual work, exoskeletons may help provide support to users and, thus, reduce physical strain on the human musculoskeletal system. However, exoskeletons still lack empirical evidence on their potential relieving effects on the human body and are, thus, not widely deployed in industrial applications yet. To investigate on exoskeleton’s impacts and promote their future adoption in the industry, industrial settings are increasingly modeled as different test scenarios in a laboratory environment. Within this frame, this paper presents a study (n = 4) investigating on effects of both an exemplary passive and active exoskeleton at an overhead screwing task. The qualitative and quantitative analysis by means of a questionnaire study as well as electromyographic investigations reveals significant support potentials of exoskeletons on users in assembly tasks.

Full text
Abstract:
Acoustic emission (AE) monitoring is a useful technique to monitor the health of a structure continuously, helping to prevent potential failure. AE are elastic waves produced and emitted during fracture processes inside a material and are recorded by sensors. Using quantitative geophysics-based methods, the recorded signals can be processed to monitor and describe the spatio-temporal growth of fracture in brittle materials such as concrete in real-time. Because of the complex nature of the recorded elastic signals and the non-homogeneous medium condition of concrete, data are usually processed manually. Combined with the high processing cost of the large datasets collected, which may exceed Terabytes, this approach has not found many real-world applications. Thus, an automated methodology is needed that can reduce costs, while maintaining high-precision, for implementation in a structural health monitoring (SHM) scheme. Here we discuss the application of a new automated and high-precision AE monitoring algorithm and software called SIMRGH [5,6] suitable for SHM of concrete structures. The core software has been developed for the laboratory-scale (in scale of centimeters) hydraulic fracture monitoring. It is up-scaled to the meters scale and works for heterogeneous media. The software works with various standard data formats and can handle trigger-based as well as continuous data. In this paper, we show some initial results of implementing the software for AE monitoring of two 4.88-meter-long concrete beams loaded in the laboratory and compare it with manually processed AE data. We were able to locate at least three up to 10 times more AE sources compared to when manual processing was used and with higher precision. If enough processing units are provided, the software can run in parallel and enable real-time SHM with excellent precision on crack geometry imaging. Future work will include implementing moment tensor inversion (MTI) to characterize AE source physics, providing valuable information for decision makers regarding the nature of the captured data.

Abstract:
Abstract High-temperature rheology testing is critical for all fracturing applications to design the well-specific breaker and additive schedule. The rheology depends on the source water quality, testing temperatures, shear profiles, and additives-stabilizers-breaker combinations used for the test. The process for each treatment requires extensive staff to fine-tune the optimal fluid formulations requiring proportional laboratory resources and time. Data analytics intelligent system design can be implemented beyond analytical mathematical correlations to reduce the time and resource requirements. A total of 820 rheology tests were conducted using the high-pressure/high-temperature (HP/HT) rheometer Chandler 5550 and ISO 13503-1 guideline. Temperatures ranged from 200 to 336°F and fluid systems consisted of borate and metallic crosslinkers. A structured database with 40 input-output features was prepared to digitize each rheology curve by incorporating the source water parameters, laboratory setup details, additive concentrations, and rheology (consistency and behavior indices) results. ML algorithms and techniques were then applied to the database to predict the rheology for given testing parameters. The algorithm inputs were prepared as the source water quality (i.e., monovalent/divalent ions, minerals, salinity, hardness etc.) and the test temperature. The outputs predicted were set to be the detailed fluid formulation for specified viscosity and fluid stability requirements. Data cleaning and ingestion were done thoroughly to remove nonphysical outliers such as bob-climbing during testing. A detailed parametric correlation study followed and revealed the impact of different parameters, especially divalent ions such as Ca+2 and Mg+2, and total dissolved solids on the rheology. The training set to holdout set ratio was fixed at 90:10 for different trials. Further, 5-fold cross validation was used to choose the hyperparameters for the final model. To predict fluid formulation/target rheology in terms of additive concentrations, which is a continuous quantity, regression-based models were attempted. Ridge regression and ensemble methods such as random forest and boosting type models were trained. Boosting-based models gave an average 88% goodness of fit (R2) for the holdout datasets. For field implementation, the model results were used to create a digital laboratory request for the laboratory technician instead of having the fracturing design engineer manually handle this task. The physics-based data-driven ML model reduced an average HP/HT runs/well from 20 to 5 yielding a 400% laboratory resource savings. This ML-based workflow is unique and does not exist in the literature. It can enable resource optimization for all large-scale fracturing projects and reduce manual laborious input for generating laboratory requests followed by trial-and-error optimizations with a potential of saving thousands of hours and reduce all the laboratory equipment maintenance costs. The technique can easily be extended to designing cementing fluids, drilling muds, and corrosion properties.

Abstract:
Although automation and robotics are widely implemented in manufacturing industry nowadays, assembly tasks and rework processes are still carried out manually by human operators because of their complexity and the need for a level of adaptability and flexibility greater than automation solutions can provide. However, manual operations exhibit variability and are subject to human errors, which could lead to unexpected delays or quality issues. Enabling traceability of manual operations is also intrinsically more challenging than for automated processes as it typically relies on the operator consistently providing direct input (e.g. HMI/operator interaction).Research suggests that augmented reality (AR) technology can contribute to enhance human-machine interaction by providing operators with a seamless digital bi-directional interface with physical systems (e.g. product or production systems), thus improving manual operations’ overall effectiveness. Existing research related to the development of AR-based solutions for manufacturing focus essentially on training and maintenance use cases, while there is limited development of applications aiming at supporting in-production operations. In addition, while AR technologies are used to provide information to the operator, the development of capabilities allowing manual process and operators to be monitored during operations, are lacking. The research presented in this paper adopt a holistic approach combining manual operation monitoring and operator feedback capabilities. The DAMPO (Digitally Augmented Manual Process Optimisation) system implements a) computer vision technologies to provide continuous operator and manual operations monitoring capabilities b) content rich and highly interactive user interfaces using screen-based 3D and AR-based information display, and c) near real-time data capture, management and processing pipelines that provide both real-time system/user interaction and collection of historical process data. The use case for this research focuses on specific manual assembly operations of safety critical components of seating systems for the automotive industry, which require precise sequence of operations and full traceability of the assembly process for audit purposes (safety critical operations). The DAMPO system is implemented in the Automation Systems Group's Digital Automation Laboratory at the University of Warwick, WMG department, UK, and is used to support both low TRL level research and direct engagement with industry on developing human centric manufacturing solutions. The DAMPO systems implement both process monitoring capabilities (i.e. data capture) and Electronic Work Instruction functions (information feedback and presentation of the operator) in view of improving process traceability and implementing no-fault forward capabilities. The DAMPO solutions combines a wide range of a) visual computing methods (fiducial, IR marker and 3D object based pose estimation), and b) information display and operator interface technologies (e.g. projected, screen-based and head-mounted AR layer display, HMI and work instruction screens with interactive 3D content, haptic feedback), which can be combined differently depending on the use case, and use case requirements such as hand free operations, complexity of work instructions or operator feedback and interactions, etc. This production-ready solution is tested and evaluated on a replicable production cell using real product and real assembly process.

Abstract:
During the last years, the car market has been characterized by a continuous request to produce new models in few years obliging OEM (Original Equipment Manufacturer) to develop more flexible assembly lines and better methods for job planning on the same lines. New standards on work organization also require new concepts for process design and for production: the human centered approach to improve manual assembly operations. In Fiat Chrysler Automobiles (FCA) this approach has been applied during process design, using “Digital Manufacturing” (DM) techniques and, during Process Industrialization and Production, using the EAWS and ErgoUAS Methods for ergonomic optimization of assembly tasks and for optimal line balancing (distributing the work load in the best way between workers along the lines). The DM approach is based on a detailed “virtual plant” where virtual mannequins interact with digital models of car’s components, equipment, containers, etc. in order to simulate and improve working conditions with many benefits on ergonomics, safety, final product quality, work organization and general production costs. However, to achieve these results, experimental data and physical validation are also necessary. For this reason, an Ergonomics Laboratory (“ErgoLab”) has been built in FCA in order to have a physical validation of design/virtual solutions.

Abstract:
Virtual labs are more and more used and realistic. An effective virtual lab was set up for both on-campus and distance learning teaching. Practice showed that virtual labs have several advantages as reducing the time taken to complete the physical labs, it could be performed during the student's own time but it requires assistance with physical lab equipment. Electric power system automation can be a difficult and expensive subject to study. Malfunction and incorrect functioning of the power systems can be the cause of major power failures in the national power grid, therefore it is important that students are exposed to realistic equipment and situations. The paper is concluded with an example of virtual labs experiment for power system automation. The Automatic Transfer System (ATS) is an essential function in a power network for assuring reliable backup power. The laboratory equipment considers a subsystem with 2 bus bars connected through a tie switch with 2 loads and a backup generator. The ATS cabinet includes 4 circuit breakers of 6kA that can be operated in manual or automatic mode. Several scenarios can be tested on the automatic transfer system, locally or remote through an Ethernet connection. The application incorporates a PC-based simulator for experiments. The virtual lab was created using OPC server which could interface the MATLAB and Simulink with stand alone applications. The advantage of the proposed structure is that in using the simulation software the distance learning teaching could incorporate the same new technology laboratory experience as teaching on-campus.

Abstract:
This article delves into the pivotal role of simulation platforms in efficiently advancing innovation projects, drawing insights from a case study involving Manulab, the Manufacturing Laboratory at the Norwegian University of Science and Technology, and regional fish industry companies. The utilization of simulation platforms emerges as a cornerstone for project success, notably in expediting the development of cutting-edge technologies and seamlessly integrating research findings into industrial practices. The study underscores how simulation platforms not only propel technology readiness level progression but also facilitate concurrent advancement along the business readiness level. This holds particularly true for simulation platforms like Unity and Omniverse by Nvidia, equipped with physics engines that meticulously simulate interactions within virtual environments. Several factors contribute to this success, including sustained engagement among stakeholders and the fostering of spin-off initiatives, which catalyze collaborative innovation. By nurturing a holistic and collaborative approach, simulation platforms serve as catalysts for translating research outcomes into tangible applications within the industrial sector. This underscores their indispensable role in propelling industrial innovation forward.

Abstract:
Particles with the largest dimension of less than 5 mm, also termed as microplastics (MPs), gained a lot of scientific and media attention in the last decade. MPs in the environment are of importance because of their potential for further fragmentation, accumulation, and impact on biota in the terres-trial and water environments. MPs research is challenging due to their diversity in size, shape, and chemical structure. For research purposes, MP particles can be purchased, but in terms of chemical structure, they properties might not correspond to the ones of MPs, found in the environment. Com-pared to purchased MPs, plastic products in the environment can contain different additives, despite being the same polymer type as purchased MPs. Therefore, for environmental studies preparation of MP particles from plastic products is preferable. In this contribution two methods for laboratory preparation of MP particles, different sizes and polymer types, are presented. Method using ultra-sound probe was found to be suitable for obtaining polyester fibres from thin sewing thread, while cryogenic milling was found to be preferable method for MPs preparation from larger and thicker plastic particles. In this way, MPs of other types of plastic (polyethylene terephthalate, polystyrene, polyvinyl chloride, polypropylene) were prepared from beforehand manually cut plastic particles, originating from everyday plastic products.

Abstract:
Abstract Thin film and micro-fabricated devices are increasingly being used in actuators, sensors, and processors deployed in smart materials. The physical survival of these devices is paramount to their usefulness but existing methods for testing and analysis are limited and challenging due to their properties. The most common test involve the manual application and removal of (unspecified) tape but does not provide a result in scientific units and has large variation (> 35%). This paper presents a study into the effects of parameters of tape application and peeling on the adhesion strength of the tape. This information was then used to create a test methodology using commonly available laboratory equipment, which would control these parameters to minimize variation and produce repeatable quantitative results. Experiments using this test methodology were performed with tape directly adhered to several different substrates as well as tape adhered to a thin film which was then peeled off of a backing. Ongoing work is seeking to identify and address different forms of failure including adhesive failure, cohesive failure, or survival.

Abstract:
The automatization of the drilling process opens the opportunity to faster reactions in case of unexpected drilling conditions, therefore reducing the risk that a drilling incident escalates to a serious situation. It also allows to push the drilling performance to be as close as possible to the limits of drillability as a function of the varying drilling conditions. But to achieve high level of drilling process automation, it is necessary to have access to accurate mathematical models of the complex physical system that is composed of the drilling rig, the drill-string, the drilling fluid and the borehole itself. As the development of accurate heat transfer, mechanical and hydraulic models and their utilization in full scale drilling applications is a huge and complex task, it is tempting to recreate drilling automatization problems in a laboratory scale setup. Because of sudden variations of the downhole drilling conditions, like when transitioning from soft to hard rock or when the bit is subject to large torque variations induced by interbedded rock layers, the boundary conditions at the bit change suddenly and require quick response from the automatic top-drive and hoisting system controllers. At a small laboratory scale, the necessary reaction times are of the order of milliseconds and therefore exclude any manual intervention. It is therefore crucial that the automatic control methods utilize precise mathematical models of the physical system to accurately estimate the limits by which the drilling process can be managed under safe conditions. For that reason, a general purpose mathematical model of small-scale drilling rigs has been developed. First, the Rayleigh-Ritz method is used to determine the deflection of the drill-string and to estimate the side forces at the contact points along the drill-string and BHA (Bottom Hole Assembly). Then the dynamic response of the power transmission system is modelled for both variable frequency drive controlled tri-phase motors and for stepper motors, including friction effects at the contact points. Friction is modelled using Stribeck theory rather than the classical Coulomb laws of friction. Finally, the expected response of 3D accelerometers, that could be placed on the outside of a BHA component, is modelled to retrieve possible inclination variations and potential vibration modes such as torsional oscillations, forward or backward whirl. The generality of the model is such that it can be used for many small-scale drilling rig designs.

Abstract:
Abstract This work aims to study the feasibility of using an online feedforward artificial neural network (ANN) to control various actuators in a hybrid fuel cell gas turbine (FC-GT) simulation plant. This unique facility known as Hybrid Performance, or HYPER, is housed at the US Department of Energy’s National Energy Technology Laboratory in Morgantown, WV. Using a cyber-physical approach, HYPER incorporates a high-fidelity FC model in software, which interacts with a gas turbine and corresponding balance of plant components in hardware, in real time. This methodology allows research of FC-GT operational issues as well as control application studies for such systems in a safe manner. An open loop perturbation of the FC model load current is used to retrieve target data from load bank and bypass airflow valve actuators which control turbine speed and FC cathode airflow respectively. The steady state FC anodic side fuel flow is also fed to a supervised ANN which learns the pattern of actuator response to the given FC perturbations. By mimicking the manually operated actuators, the FC solid temperature gradient is maintained within safe operating bounds. The feedforward ANN is useful for its simplicity and flexibility in controlling a variety of desired actuator responses based on input combinations. The benefits and drawbacks of using ANN’s are discussed, as well as suggestions for improvement.
