Noise and PID control for low consistency pulp refiner
Creators: name: Reynolds, Byron
name: Pang, Haotian
name: Zhang, Lionel
Publisher: name: The University of British Columbia
Year: 2011

description: The main objective of this project was to remove the noise on various measurement signals for the low consistency pulp refiner, and implement a controller for the gap distance in two different modes of operation. The project is sponsored by Dr. Jens Heymer and Dr. James Olson from UBC Mechanical Engineering. A design of the noise reduction algorithm and gap size control algorithm was implemented and tested by Byron Reynolds, Haotian Pang and Lionel Zhang. Spectrum analysis showed that the majority of the noise on the gap signal is above 20Hz. As a result, a 12Hz Butterworth low pass filter of order 10 was chosen to reduce the noise on raw gap signal in volts. As the filtered signal is converted to size in mm, noise is also amplified. Therefore, an averaging of every 15 samples was employed to keep the signal clean enough so that it does not compromise the performance of the gap size controller. It was found after filtering and averaging of every 15 samples; the gap size uncertainty can be kept under 0.02mm, which meets the specification. Before the gap size controller was implemented, a safety algorithm was developed and fully tested to ensure that no plate clashing or equipment damage occurs as it constantly checks the current gap size and keeps the gap size in a safe range. Based on the results from the actual effects of the P, D and I term. It was determined that a traditional PID controller is not suitable for the system due to the fact that the system is never stable with any value of P, D and I gain. The instability of the system is likely caused by the non-linearity and slow response of the actuator. Consequently, a combination of proportional control, pre-control and lock algorithm was used as the final gap size controller. The testing results showed that it is capable of moving the plate to any targeted position with a precision and maximum overshoot of ±0.05mm. Also, the gap size can be changed by 1mm within 10 seconds. The energy based mode of the position controller cannot be fully implemented and tested prior to the completion of this report due to some issue with the refiner that needs to be fixed before it can be run properly with load. All software codes including the filters and the gap size based position controller have been provided to our sponsor Dr. Jens Heymer. A list of recommendations is also included in this report, aiming to further reduce noise, help compensate for signal delay caused by averaging, and some suggestions on safety.
Dark rover rocker-bogie optimization design

Year: 2011

description: There were three goals for this project: to build an inexpensive test track, to design a rocker-bogie suspension system, and to quantify changes in energy usage based on the rover's geometry. We successfully built a test track capable of repeatable tests, an easily modifiable rocker-bogie system, and found some very favourable results through testing. We tested the rover by running it along the test track and monitoring the instantaneous current and voltage values of each drive motor. By repeating the run several times at a fixed rover configuration we were able to get average values for the run. We then integrated this data and produced a value of energy consumption per configuration. This is the main metric within our report. The most optimal configuration that we tested in terms of minimal energy consumption was with a 90 degree primary angle, back hole mounting, standard slot length. Further tests were done about this point and we also found that energy consumption decreases if the primary angle between the rocker and bogie is increased by tens of degrees, and the slot position is shortened. Overall, the optimal configuration used 15% less energy than the worst configuration we tested, and 6:4% less energy than the next least energetic setup. Moving the slot from the standard mounting position to the shortened one re- duced the energy consumption by 2:5%. These results indicate that our tesing setup produces useful results which can be used to guide further design of the rocker-bogie system such that energy consumption is minimized. After conducting this project and analyzing the results we have defined four main recommendations for future work. 1. Further testing to be done with a six wheeled rover chassis. 2. Include more realistic and difficult obstacles on the testing tracks. 3. Use higher quality motors and wheels on the rover. 4. Design the next rover with three driving wheels, instead of two.

description: Quantum field theory predicts a nonlinear response of the vacuum to strong electromagnetic fields of macroscopic extent. This fundamental tenet has remained experimentally challenging and is yet to be tested in the laboratory. A particularly distinct signature of the resulting optical activity of the quantum vacuum is vacuum birefringence. This offers an excellent opportunity for a precision test of nonlinear quantum electrodynamics in an uncharted parameter regime. Recently, the operation of the high-intensity laser ReLaX provided by the Helmholtz International Beamline for Extreme Fields (HIBEF) has been inaugurated at the High Energy Density (HED) scientific instrument of the European XFEL. We make the case that this worldwide unique combination of an x-ray free-electron laser and an ultra-intense near-infrared laser together with recent advances in high-precision x-ray polarimetry, refinements of prospective discovery scenarios, and progress in their accurate theoretical modelling have set the stage for performing an actual discovery experiment of quantum vacuum nonlinearity.

description: Photonic neural networks (PNNs) are fast in-propagation and high bandwidth paradigms that aim to popularize reproducible NN acceleration with higher efficiency and lower cost. However, the training of PNN is known to be challenging, where the device-to-device and system-to-system variations create imperfect knowledge of the PNN. Despite backpropagation (BP)-based training algorithms being the industry standard for their robustness, generality, and fast gradient convergence for digital training, existing PNN-BP methods rely heavily on accurate intermediate state extraction or extensive computational resources for deep PNNs (DPNNs). The truncated photonic signal propagation and the computation overhead bottleneck DPNN's operation efficiency and increase system construction cost. Here, we introduce the asymmetrical training (AsyT) method, tailored for encapsulated DPNNs, where the signal is preserved in the analogue photonic domain for the entire structure. AsyT offers a lightweight solution for DPNNs with minimum readouts, fast and energy-efficient operation, and minimum system footprint. AsyT's ease of operation, error tolerance, and generality aim to promote PNN acceleration in a widened operational scenario despite the fabrication variations and imperfect controls. We demonstrated AsyT for encapsulated DPNN with integrated photonic chips, repeatably enhancing the performance from in-silico BP for different network structures and datasets.

description: We study the late time exponential decay of the survival probability $S_\pm(t,a|x_0)\sim e^{-θ(a)t}$, of a one-dimensional run and tumble particle starting from $x_00$. We find that the decay rate $θ(a)$ of the survival probability has strong dependence on the location $a$ of the absorbing boundary, which undergoes a freezing transition at a critical value $a=a_c=(v_0-α)\sqrt{v_0^2-α^2}/(2αγ)$, where $v_0>α$ is the self-propulsion speed and $γ$ is the tumbling rate of the particle. For $a>a_c$, the value of $θ(a)$ increases monotonically from zero, as $a$ decreases from infinity, till it attains the maximum value $θ(a_c)$ at $a=a_c$. For $0

Publisher: name: The University of British Columbia
Year: 2011

description: This project is focused on a calculation of the true cost of the planned oil pipeline from Kitimat on British Columbia’s North Coast to the Alberta tar sands. The project will consider the value of an attempt to evaluate the economic consequences of the proposal for local communities and will further attempt to factor in and consider the environmental and cultural costs arising from the destruction and pollution of habitat and the destruction and trespass on First Nations lands and cultural property. The project was undertaken on behalf of the Dogwood Initiative who requested a consideration of the potential for techniques of economic evaluation to be applied to the Enbridge Project. This paper assumes particular importance in the light of the upcoming federal election in Canada, which is scheduled to take place on the 2nd of May 2011. A key goal for the Dogwood Initiative in the coming weeks will be to ensure that this issue maintains the longest possible lifespan, remaining in the public eye long after the election is over.

description: The goal of this paper is to analyse the societal preparedness for CCUS in selected European countries. Societal prepardness is understood as a combined analysis of political and societal perspectives. The countries of analysis include the Netherlands and UK as two frontrunners. Furthermore, Poland, a country currently highly dependent on coal, Germany, Spain and France as highly industrialised countries are included. Overall these six countries are among the highest emitters in Europe. The analysis assembles ongoing activities, the overarching political framework and climate goals; specific regulation and goals for CCUS and existing fundings instruments; the state of knowledge about the public acceptance in these countries. None of the countries seems to be on a straightforward path towards CCUS and especially questions around social acceptance are open in most countries. Most advanced in is probably the UK which combines a favourable regulatory framework with relevant past and recent experiences including high expertise from the oil and gas industry with comparatively favourable perception. The Netherlands have also far developed. In France and Spain some relevant experience are available and regulation has progressed to a certain level, however, the role of CCUS for decarbonisation is not clearly defined in the two countries. Germany and Poland are least developed towards realising CCUS and both miss important enabling regulatory frameworks as well as funding schemes. At the same time, CCUS is vaguley part of political strategies. With regard to social acceptance both countries face challenges.

description: Electrification is one of the key means to decarbonize the transportation sector, but the growing number of electric vehicles (EVs) in the market contributes to the risk of bringing existing electricity grids to their limits. Smart and bidirectional charging offer a solution to alleviate grid load and increase the use of renewable electricity. We conducted 12 expert interviews with smart charging stakeholders in Germany and a consumer study with 689 German EV users to identify opportunities, risks, barriers, and feasibility, as well as user preferences related to smart charging tariff designs. We found a generally positive view among the stakeholders, and identified barriers that need to be overcome before a large-scale deployment of smart charging. Consumers are generally willing to accept smart charging, with financial compensation for offering flexibility being the most important design attribute. We discuss implications in light of the reformulation of pertinent regulations in Germany.
Mineralogical and Geochemical Characterization of Supergene Carbonate-hosted Nonsulphide Zn-Pb Mineralization in Southern and Central British Columbia.
Creators: name: Keevil, Halley K.
Publisher: name: The University of British Columbia
Year: 2011

description: Carbonate-hosted nonsulphide base metal deposits form in supergene environments as base metal sulphides are oxidized and chemical weathering causes the metals to be leached out and deposited as metal-bearing gossans. The metals can be deposited by direct-replacement as nonsulphide minerals directly above the sulphide ore, or can travel away from the underlying sulphides with percolating water and be deposited as wall-rock-replacement deposits. Direct-replacement deposits, known as “red ores”, are usually rich in iron oxides, occur in association with primary sulphide minerals, and may contain economic concentrations of zinc and lead. Wall-rock-replacement deposits, known as “white ores”, are typically less oxidized, are not associated with primary sulphide minerals, and contain higher concentrations of zinc but lesser amounts of lead and iron. Both forms of mineralization have been recognized as valid exploration targets in British Columbia, but detailed mineralogy and chemistry of representative deposits is needed to better establish exploration models. Petrography, X-ray diffraction, and scanning electron microscopy analyses were completed on select nonsulphide deposits, i.e., Red Bird, Lomond, and Oxide in the Salmo district of the Kootenay terrane, and Cariboo Zinc in the Quesnel Lake district of the Cariboo terrane. Sulphide protore to the nonsulphide deposits of the Salmo district was also studied by analyzing samples from the Reeves MacDonald, HB, and Jersey-Emerald properties. At the Lomond deposit, there is extensive oxidation and cerussite occurs as a lead nonsulphide phase within vugs. At the Red Bird prospect, hemimorphite is the predominant nonsulphide mineral, with remnants of hydrozincite on the crust of oxidized samples. At the Cariboo Zinc property, smithsonite is the most abundant zinc nonsulphide phase, though hemimorphite is also present. Lead nonsulphides on the property consist of anglesite and cerussite. The Oxide prospect is not associated with sulphide ore and the main nonsulphide phases are hemimorphite and hopeite. All of the nonsulphide deposits studied fit the direct-replacement style of nonsulphide mineralization, with the exception of the Oxide prospect, which shows traits of wall-rock-replacement style mineralization. Though the nonsulphide deposits differ to some extent in mineralization styles, all fit the general supergene model of nonsulphide mineralization and further characterization can assist in creating an exploration model for similar deposits in BC and the rest of the Cordillera.

High-density storage

description: In the dynamic and constantly evolving world of intralogistics, it is of great importance to make well-informed decisions when selecting technologies for a specific application. This whitepaper examines two rack systems for high-density storage: the Pallet Flow System and the semi-automatic Pallet Shuttle System. Both solutions cover a similar range of applications and offer different advantages and disadvantages through their functions and mechanisms. In addition to budget considerations, relevant factors for technology selection include throughput requirements, operational strategies, and product or industry-specific requirements. Often, the degree of automation is also highlighted as a key consideration in decision-making. However, automation alone should not be the sole reason for implementation. It should be justified by other factors such as increased efficiency or reduced operating costs. The goal of this whitepaper is to comprehensively compare both technologies and present the strengths, limitations, and application opportunities of each storage system. Furthermore, decision-makers will be provided with meaningful examples of technology implementation through a calculation model.

description: Learning Continuous-Time Dynamic Graphs (C-TDGs) requires accurately modeling spatio-temporal information on streams of irregularly sampled events. While many methods have been proposed recently, we find that most message passing-, recurrent- or self-attention-based methods perform poorly on long-range tasks. These tasks require correlating information that occurred "far" away from the current event, either spatially (higher-order node information) or along the time dimension (events occurred in the past). To address long-range dependencies, we introduce Continuous-Time Graph Anti-Symmetric Network (CTAN). Grounded within the ordinary differential equations framework, our method is designed for efficient propagation of information. In this paper, we show how CTAN's (i) long-range modeling capabilities are substantiated by theoretical findings and how (ii) its empirical performance on synthetic long-range benchmarks and real-world benchmarks is superior to other methods. Our results motivate CTAN's ability to propagate long-range information in C-TDGs as well as the inclusion of long-range tasks as part of temporal graph models evaluation.

description: Ontologies are shared formal conceptualizations of specific domains. They serve as foundations for knowledge representation and reasoning as well as standards for information exchange and interoperability. This White Paper gives a concise overview on the challenges of developing and applying ontologies for supporting crisis management. Firstly, we will introduce fundamental concepts related to ontologies and knowledge engineering. Then, we will discuss the role ontologies play for (a) enabling probabilistic and causal reasoning, (b) defining interoperability solutions and (c) creating a resilience data space. Thereafter, we will review a selection of existing resources and their reusability. Finally, we will conclude and give recommendations on further work.
Participation catalyzing change : a case for tenant participation in BC Housing’s planning for sustainability as a means to encourage environmentally sustainable behaviors
Creators: name: Vandecasteyen, Ryan
Publisher: name: The University of British Columbia

description: BC Housing is a provincial crown agency under the Ministry of Energy and Mines (Minister Responsible for Housing), and is mandated to fulfill the government’s commitment to the development, management and administration of subsidized housing as reflected in an order-in-Council under the Housing Act establishing the BC Housing in 1967 (BC Housing, 2007a). In the last five years, the Province of British Columbia has set out to tackle the issue of climate change, and under the Greenhouse Gas Reduction Target Act introduced in 2007, BC Housing must become a carbon neutral organization by the end of June 2011 (BC Housing, 2010a). In 2008, BC Housing introduced the livegreen plan as BC Housing’s sustainability strategy, providing a roadmap to help fight climate change by reducing the environmental footprint of new and existing social housing in BC (BC Housing, 2010a). The livegreen plan was created through an employee engagement process, and has resulted in a large number of green-energy retrofits, reductions in housing energy consumption and greenhouse gas emissions, new buildings being constructed to LEED standards, and the fostering of environmentally sustainable behaviors for BC Housing employees (BC Housing, 2010a). To further reduce BC Housing’s environmental footprint BC Housing is now looking for a way to engage its tenants in environmentally sustainable behaviors; this report outlines some initial findings for a means to reach this goal. To facilitate and engage its tenants in environmentally sustainable behaviors, BC Housing must incorporate meaningful tenant engagement into its planning and decision-making processes for actions, programs and policies.

description: In 2017 a definition of spiral tilings was given, thereby answering a question posed by Grünbaum and Shephard in the late 1970s. The author had the pleasure to discuss the topic via e-mail with Branko Grünbaum in his 87th year. During this correspondence the question arose whether a spiral structure (given a certain definition of it) could be recognized automatically or whether "to some extent, at least, the spiral effect is psychological", as Grünbaum and Shephard had conjectured in 1987 (see exercise section of chapter 9.5 in "Tilings and Patterns"). In this paper, an algorithm for automatic detection of such a tiling's spiral structure and its first implementation results will be discussed. Finally, the definitions for several types of spiral tilings are refined based on this investigation.

description: Compared to conventional manufacturing technologies, additive manufacturing (AM) offers great design freedom, the integration of functions into components, new lightweight construction concepts and high material efficiency. This technology is increasingly coming into focus in aerospace and turbomachinery engineering, especially the Laser Powder Bed Fusion (LPBF) process. LPBF is already being used for some aerospace components that are often subject to high thermal and mechanical loads. Depending on the component geometry, support structures are required for additive manufacturing, which then have to be removed, usually by machining. Among others, the use of material with specifically induced porosity is suitable as a support structure. This ensures good heat dissipation and thus homogeneous component properties, high retention forces and short process times in the LPBF process. However, the machinability of porous, additively manufactured material has hardly been researched to date. This paper therefore presents the results of machinability investigations with porous, additively manufactured Inconel 718. The investigations included the analysis of active cutting force, cutting tool wear, surface finish and chip geometry in the milling process with tungsten carbide cutting tools. It was found that with the porous material, the dominant type of wear is early starting chipping of the cutting tool edges. The active force decreases with increasing porosity. Partial smearing of the pores was observed on the milled surfaces. The chips of the porous material show a disrupted surface. In future investigations, the aim is to improve the wear behaviour when milling porous Inconel 718.

AI in Logistics

description: This white paper on Artificial Intelligence (AI) in Logistics targets ALICE network members and organizations interested in starting AI projects in the logistics field. AI currently permeates all sectors and industries and becomes an increasingly important technology. The characteristics of the logistics industry, such as a fluctuating consumer market, multiple actors with opposing goals, and complex optimization problems, make it highly suitable for AI applications. AI methods can capture the complex relationships in logistics environments, leveraging the increasing availability of data to make logistics processes more efficient and sustainable. The European Union (EU) supports the development and use of AI by creating a regulatory framework called the EU AI Act, aiming to ensure the safety, transparency, traceability, non-discrimination, and environmental friendliness of AI systems used in the EU. After exploring the foundations of AI, the white paper provides application examples for AI in logistics from members of the ALICE network. The application examples are clustered according to their application domain (ports, intralogistics, and transport management), as well as the task that an AI algorithm on (sensing, thinking, acting). Finally, the white paper addresses common challenges of starting and AI project and ways to overcome them.

description: This paper proposes Bayesian Adaptive Trials (BAT) as both an efficient method to conduct trials and a unifying framework for evaluation social policy interventions, addressing limitations inherent in traditional methods such as Randomized Controlled Trials (RCT). Recognizing the crucial need for evidence-based approaches in public policy, the proposal aims to lower barriers to the adoption of evidence-based methods and align evaluation processes more closely with the dynamic nature of policy cycles. BATs, grounded in decision theory, offer a dynamic, ``learning as we go'' approach, enabling the integration of diverse information types and facilitating a continuous, iterative process of policy evaluation. BATs' adaptive nature is particularly advantageous in policy settings, allowing for more timely and context-sensitive decisions. Moreover, BATs' ability to value potential future information sources positions it as an optimal strategy for sequential data acquisition during policy implementation. While acknowledging the assumptions and models intrinsic to BATs, such as prior distributions and likelihood functions, the paper argues that these are advantageous for decision-makers in social policy, effectively merging the best features of various methodologies.

description: As the competition of the cabinetry industry becomes more and more intense, improving the efficiency of production, reducing the cost and increase the quality of products are increasingly important for companies to defend the market share and remain the competitive statues in the industry. The implementation of fully automatic CNC router is one effective way to deal with the current challenges. Although CNC routers require relatively higher capital investment, they can increase the accuracy, productivity, flexibility and simplicity of the production significantly. In reality, these factors are all keys to success for the cabinetry companies. Nickels Cabinets is one example that shows the change of the manufacturing method. Its outstanding performance in the industry proves that the automatic operating system is the future trend in the secondary wood industry. According to the cost analysis, we can see the present worth of the total cost of investing and operating a CNC router for ten years.

description: Die Digitalisierung von Material- und Informationsflussprozessen im Lager birgt enormes Potenzial, Prozesse, Leistung und Ergonomie zu verbessern. Die Pick-by Light-Technologie (PbL) stellt dabei eine Möglichkeit dar, den manuellen Kommissionierprozess zu digitalisieren und die papierbasierte Pickliste abzulösen. Im Rahmen des Transferprojekts »Light it Up!«, gefördert durch das Mittelstand-Digital Zentrums Ruhr-OWL (MDZ), wurde eine E-Paper-basierte PbL-Technologie in ein Warehouse-Management-System (WMS) integriert und hinsichtlich der Kognitiven Ergonomie überprüft (s. Abbildung 1). An den Regalfächern installierte E Paper-Displays bieten ein digitales Abbild sämtlicher Informationen im Kommissionierprozess. Die Kommunikation der digitalen Fachanzeigen erfolgt dabei mit einem WMS. Der erfolgreiche Praxiseinsatz setzt die Anbindung eines WMS an die E-Paper-Displays voraus, was aufgrund fehlender Integrationsstandards für Unternehmen eine Herausforderung darstellen kann. Gemeinsam mit den Projektpartnern Logistics Reply und ekko GmbH implementierte das Fraunhofer-Institut für Materialfluss und Logistik IML in dem Pilotprojekt »Light it Up!« die Technologie in der Forschungsinfrastruktur »Picking Lab« der Initiative »Leistungszentrum Logistik und IT« am Standort in Dortmund. Das Whitepaper stellt ein standardisiertes Vorgehen zur Integration wie auch die Ergebnisse einer Studie zur Kognitiven Ergonomie vor, um Unternehmen bei der Entscheidung für und der Implementierung von PbL zu unterstützen.
