Multivariate modelling of extreme load combinations for wind turbines
Creators: name: Dimitrov, Nikolay
Publisher: name: The University of British Columbia
Year: 2015

description: We demonstrate a model for estimating the joint probability distribution of two load components acting on a wind turbine blade cross section. The model addresses the problem of modelling the probability distribution of load time histories with large periodic components by dividing the signal into a periodic part and a perturbation term, where each part has a known probability distribution. The proposed model shows good agreement with simulated data under stationary conditions, and a design load envelope based on this model is comparable to the load envelope estimated using the standard procedure for determining contemporaneous loads. By defining a joint probability distribution and full return-period contours for multiple load components, the suggested procedure gives the possibility for determining the most critical loading direction in a blade cross section, or for carrying out reliability analysis on an entire cross section.

title: Urban Design for Mussolini, Stalin, Salazar, Hitler and Franco During the Interwar Period
Creators: name: :None
Publisher: name: Bauhaus-Universität Weimar

Subjects: subject: Urbanität
subject: 300

description: Urban design played a central role for the European dictatorships during the 20th century, it served to legitimate the regime, to produce agreement, to demonstrate power, efficiency and speed, it communicated the social, as well as design projects, of the dictatorial regimes domestically and internationally, it tied old experts, as well as new, to the regime. Dictatorial urban design also played an important role after the fall of the dictatorships: It became the object of structural and verbal handling strategies: of demolition, of transformation, of reconstruction, of forgetting, of suppressing, of re-interpretation and of glorification. The topic area is, therefore, both historical and relevant to the present day. The discussion of the topic area is, like it or not, always embedded in the present state of societal engagement with dictatorships. In order to even be able to discuss all of these aspects, different conceptual decisions are necessary. In retrospect, these may seem to many as self-evident, although they are anything but. Our thesis is that there are three methodological imperatives, especially, which allow an expanded approach to the topic area “urban design and dictatorship”. First and above all, the tunnel view, focused on individual dictatorships and neglecting the international dimension, must be overcome. Second, the differences in urban design over the course of a dictatorship, through an appropriate periodisation, should be emphasised. Third, we must strive for an open, flexible, but complex concept of urban design. The main focus lies on the urban design of the most influential dictatorships of the first half of the 20th century: Soviet Union, Fascist Italy and Nazi Germany, including the urban design of the autarky periods in Portugal and Spain. After all, urban design is not just a product of specific historic circumstances. It is a form that continues to have long-term effects, which demonstrates its usefulness and adaptability throughout this process. The urban design products undoubtedly still recall the dictatorial rule under which they were created. However, they are more than a memory space. They are also a living space of the present. They can and should be discussed with respect to their spatial and functional utility for today and tomorrow. Such a perspective is a given for the citizens of a city, but also for city marketing, having marvellous consequences. Only when we do not exclude this dimension a priori, even in academic discussions, can we do justice to the products of dictatorships. And finally, the view of the urban design of dictatorships can and must contribute to the questioning of simplified and naive conceptions of dictatorships. With urban design in mind, we can observe how dictatorships work and how they were able to prevail. In Europe, these questions are of the highest actuality.

description: Major earthquakes can extensively transform the above and below ground natural and built environments of cities, leading to decreased drainage system capacity and, ultimately, to Increased Flooding Vulnerability (IFV). This has been the case for Christchurch city in New Zealand, which experienced the 2010 to 2011 Canterbury Earthquake Sequence (CES). These seismic events were followed by extreme rainfall in March-April 2014, with much of the city experiencing damaging flooding. This paper uses data from a Christchurch case study to extend a recently-developed infrastructure damage simulation tool to the probabilistic assessment of earthquake-altered flood risk in a built environment. In particular, the focus is on the IFV caused by the earthquake-induced damage to the pipeline component of Christchurch’s storm water system, which was analysed at both connectivity and capacity levels. The probabilistic analysis was carried out via a plain Monte Carlo simulation, enabling the uncertainty affecting several key parameters to be taken into account. Final analysis results are presented spatially and in the form of cumulative distribution of flood height, the latter being an impact metric of great interest for infrastructure owners and emergency managers.
Operational modal analysis using variational Bayes
Creators: name: Li, Binbin
name: Der Kiureghian, Armen
Publisher: name: The University of British Columbia
Year: 2015

description: Operational modal analysis is the primary tool for modal parameters identification in civil engineering. Bayesian statistics offers an ideal framework for analyzing uncertainties associated with the identified modal parameters. However, the exact Bayesian analysis is usually intractable due to the high computation demanding in obtaining the posterior distributions of modal parameters. In this paper, the variational Bayes is employed to provide an approximated solution. Working with the state space representation of a dynamic system, the joint distribution of the state transition matrix and observation matrix as well as the joint distribution of the process noise and measurement error are firstly obtained analytically using conjugate priors, then the distributions of modal parameters are extracted from these obtained joint distributions based on sampling because no closed form solution exists. A numerical simulation example demonstrates the performance of the proposed approach. The variational Bayes yields a consistent estimation of modal parameters although the variability is slightly under-estimated. Moreover, the variational Bayes is more flexible than the Laplace approximation and much more efficient than Monte Carlo sampling.

description: The Afghanistan War (2001-2021), the most protracted military commitment in Australian history, provided a basis through which to investigate the similarities and differences of reporting in the Australian newspapers. This thesis analysed the Afghanistan War coverage from 2008 to 2013 in the Australian, the Age, Herald Sun and the West Australian. The content analysis and interviews with News Corporation, Fairfax and Seven West Media journalists explored the impact of embedded journalism. This thesis concluded that the privileging of Western government-military viewpoints — in the absence of counter-hegemonic voices — conditioned the Australian story of the war that was conservative and flawed.
Chinese foreign direct investment inflows and the impact of institutional quality on infrastructure developments in Nigeria.

description: This thesis complements current studies by focusing on Chinese foreign directinvestment inflows to Nigeria’s infrastructure sector. China in recent time, has become amajor source of OFDI, through its Belt and Road Initiative. The current study empiricallytested the impact of Chinese FDI inflows to Nigeria’s infrastructure both in the short and longrun. The current study also compared FDI inflow from three major trading and investingpartners with Nigeria, which are the United States, the United Kingdom and in recent timeChina, while also interacting these variables with the variable of effective institution, this isto test the effect of quality intuition on FDI inflows to Nigeria’s infrastructure. The currentstudy also used the Toda-yamamotor casualty to test for direction of causality amongvariable.The empirical findings indicate that Chinese FDI has had a minimal effect oninfrastructure development over both short-term and long-term periods. The study’s empiricalfindings also indicate substantial variation in how FDI affects infrastructure, contingent uponthe source country and the quality of institutions. The study underscores the pivotal role ofinstitutional quality in shaping the effectiveness of FDI, in promoting infrastructuredevelopment in Nigeria. Also based on the findings of the study, which explored directionalrelationships between various factors and the logistics performance index as a proxy forinfrastructural development, several conclusions were drawn. One of which is that, ChineseForeign Direct Investment (FDI) and infrastructural development demonstrated bidirectionalcausality, indicating a mutually reinforcing relationship. However, the current level ofinstitutional quality, represented by government effectiveness, did not significantly influenceinfrastructure investments. To enhance infrastructure development in Nigeria, severalactionable recommendations were proposed. Firstly, it is important to diversify ChineseForeign Direct Investment (FDI) from primarily extractive industries to sustainableinfrastructure projects. This shift can be facilitated through the implementation of targetedpolicy incentives that attract investment into critical sectors such as transportation, energy,and telecommunications. Also, among other conclusions, enhancing governance structures iscrucial for improving the effectiveness of FDI. This can be achieved by strengtheningtransparency and regulatory frameworks.
Sensitivity of ground motion simulation validation criteria to filtering

Publisher: name: The University of British Columbia
Year: 2015

description: The validation of ground motion synthetics has received increased attention over the last few years due to advances in physics-based deterministic and hybrid simulation methods. Validation of synthetics is necessary in order to determine whether the available simulation methods are capable of faithfully reproducing the characteristics of ground motions from past earthquakes. Some validation methods use filters to evaluate the quality of the fit between synthetics and data within different frequency bands. This is done, primarily, to weight the contribution of different wavelengths so that low frequencies are given more weight than high frequencies. One particular method of interest is the goodness-of-fit (GOF) criterion introduced by Anderson (2004). In this method, the degree of similarity between two signals is quantified by means of a set of ten (error) metrics which are projected on a 0–10 scoring scale. These metrics are based on ground motion characteristics commonly used in seismology and earthquake engineering. The scores are used to evaluate each given pair of signals in the three components of motion and within different frequency ranges. The scores of each frequency band, component, and metric are then combined to obtain a final GOF score. In this paper we study the sensitivity of the GOF scores, and thus the sensitivity of the validation itself, to the filtering process when different filter parameters are considered. Our initial analysis of results show that GOF methods are susceptible to the design of filters. The filter’s order, for instance, seems to significantly affect the interpretation of the validation— especially for metrics that are time-dependent (e.g., peak ground response). We evaluate the implications of the variability in GOF scores on the case study of the 2008 Mw 5.4 Chino Hills earthquake, and investigate the sensitivity of GOF criteria to the type of filters used to decompose the signals. We analyze the consistency and correlation of the results obtained using various metrics by means of a filtering fitting function. Our work indicates that elliptic infinite impulse response filters lead to more reliable results, over other more commonly used filters; and we provide guidance on the selection of elliptic filter parameters.

description: In this study, we present a Bayesian method for efficient collapse response assessment of structures. The method facilitates integration of prior information on collapse response with data from nonlinear structural analyses in a Bayesian setting to provide a more informed estimate of the collapse risk. The prior information on collapse can be obtained from a variety of sources, including information on the building design criteria and simplified linear dynamic analysis or nonlinear static (pushover) analysis. The proposed method is illustrated on a four-story reinforced concrete moment frame building to assess its seismic collapse risk. The method is observed to significantly improve the statistical and computational efficiency of collapse risk predictions compared to alternative methods.

description:      What the Engine Does (Core Logic Only)

The Fractal Correction Engine is a modified double pendulum simulation that:

Calculates motion using real-time physics:

Solves angular acceleration (a1, a2) at each frame

Updates angular velocity (omega1, omega2) and position (theta1, theta2)

Tracks tip movement and energy:

Converts angles to Cartesian positions (x1, y1, x2, y2)

Calculates kinetic and potential energy per timestep

Logs all values for visualization

Applies predictive correction:

Compares expected vs actual tip path

If deviation is high and chaos mode is off, it injects small torque (adds to omega1 and omega2) to nudge the system back into stability

Toggles between chaos and stability:

If the system is losing energy → allow chaos (no correction)

If energy is increasing rapidly → enter correction mode to stabilize

In short:It simulates chaotic motion, watches for instability, and applies smart corrective torque when needed — unless chaos is desirable.
Risk measures in engineering design under uncertainty

Publisher: name: The University of British Columbia
Year: 2015

description: Engineering decisions are made under substantial uncertainty about current and future system cost and response. A risk-neutral decision maker would rely on expected values when comparing designs, while a risk-averse decision maker might adopt nonlinear utility functions or failure probability criteria. The paper shows that these models for making decisions fall within a framework of risk measures that includes many other possibilities. The paper provides an overview of the framework, highlights benefits derived from certain risk measures, and gives a truss design example.

description: In this study, the incremental dynamic analysis method or IDA (Vamvatsikos and Cornell, 2002) is used in the collapse performance evaluation of a reinforced concrete building subjected to near-fault ground motions. The analysis is performed for two sets of ground motions: (1) a recorded dataset based on FEMA P695 (2009); and (2) a synthetic dataset corresponding to the recorded one and generated using the parameterized stochastic model of near-fault ground motion by Dabaghi and Der Kiureghian (2014). The results show that the synthetic dataset tends to slightly underestimate the collapse capacity of the studied building compared to the recorded dataset. Despite this fact, the study demonstrates the potential of using synthetic ground motions in future applications of performance-based earthquake engineering.

Subjects: subject: International and Comparative Education

description: Since the 1950’s, NGOs have featured prominently in education, development and social change movements in Latin America since the 1950’s. This paper provides concrete examples of the roles NGOs have played in research and development. An analysis of NGO characteristics and a functional typology based on their delivery of services, research focus and grassroots action is provided. The NGO phenomenon is an emerging reality of great significance to Latin American development processes. Donor agencies, governments and NGOs themselves are expressing the need to better understand this social phenomenon, which bears promise in its potential capacity to respond to critical development issues at a time when the world is characterized by "the persistence of poverty and the declining availability of financial resources" (Brown & Korten, 1988). The huge number of NGOs, their overwhelming heterogeneity and the diverse contexts in which they operate within Latin America make it extremely difficult to draw generalizations about their reality that would be universally true. Nonetheless, this exploratory discussion paper will attempt to provide a general picture of specific characteristics that depict the nature of NGOs in Latin America and will offer some initial responses to key questions posed by the International Development Research Center of Canada (IDRC). This paper does not pretend to provide definitive answers to these questions, but rather it will share the author's observations and reflections based on personal experience working with various NGOs in Central and South America, a review of the sparse literature that exists on Latin American NGOs, and interviews with directors of NGOs in Bolivia, Chile, Colombia, Costa Rica, Ecuador, Guatemala and Peru.

Publisher: name: The University of British Columbia
Year: 2015

description: This article aims to introduce spatial variability effect on the behavior of extended structures as the sheet piles. The importance of these aspects can provide elements of response to experts in charge of the standards of design for these structures. Two main problems are identified, the first one is about the most appropriate way to model the variability of soil and its interaction with the sheet pile. The second one is to take into account the uncertainties and their propagation through a model. A 2-D mechanical model of the sheet pile has served to propagate the soil variability and the system-parameter uncertainties and allowed to study the response of the different structural elements of the structure. The spatial soil heterogeneities show clearly its effect on the behavior of the structure. This analysis has opened up new possibilities to advance in researches on longitudinal aspects for these structures.

description: Der Bauablauf unterliegt vielen Unwägbarkeiten. Von besonderer Bedeutung ist dieses Problem im Umfeld der Revitalisierung von Bauwerken. In weiten Teilen sind die auszuführenden Arbeiten nur schwer im Vorfeld planbar. Die Ursachen hierfür liegen großteils in der Problematik des Bauens im Bestand und dem aus wirtschaftlichen Gründen geringen Umfang von Analysen. Häufig treten verdeckte, im Vorfeld der Baumaßnahme nicht erkannte Schäden auf oder Materialstrukturen und Bauteilqualitäten wurden in der Planung unzureichend berücksichtigt. Alte Ausführungsunterlagen sind oft nicht verfügbar. Viele zur Ausführung bestimmter Arbeiten nötige Informationen fehlen und werden erst zum unmittelbaren Ausführungszeitpunkt bekannt. Einzelne Arbeiten sind nur schwer kalkulierbar bzw. planbar. Sie sind in Art und Umfang zunächst nicht bekannt und müssen gegebenenfalls als neue Vorgänge im Plan berücksichtigt werden. Diese besondere Situation bedarf einer gezielten Berücksichtigung. Die Planung des Bauablaufes muss in einer flexiblen und leicht anpassbaren Art und Weise erfolgen. Im folgenden Beitrag wird ein Ansatz zur Entwicklung eines solchen Prozessmodells vorgestellt, der im Rahmen des SFB 524 >Werkstoffe und Konstruktionen für die Revitalisierung von Bauwerken< an der Bauhaus-Universität Weimar untersucht und vorangetrieben wurde und wird.

description: Legionella pneumophila, the leading cause of Legionnaires’ disease in the United States, is found in lakes, ponds, and streams but poses a health risk when it grows in building water systems. The growth of L. pneumophila in hot water systems of healthcare facilities poses a significant risk to patients, staff, and visitors. Hospitals and long-term care facilities account for 76% of reported Legionnaires’ disease cases with mortality rates of 25%. Controlling L. pneumophila growth in hot water systems serving healthcare and hospitality buildings is currently achieved primarily by adding oxidizing chemical disinfectants. Chemical oxidants generate disinfection byproducts and can accelerate corrosion of premise plumbing materials and equipment. Alternative control methods that do not generate hazardous disinfection byproducts or accelerate corrosion are needed. L. pneumophila is an obligate aerobe that cannot sustain cellular respiration, amplify, or remain culturable when dissolved oxygen (DO) concentrations are too low (< 0.3 mg/L). An alternative method of controlling L. pneumophila growth by reducing DO levels in a hot water model system using a gas transfer membrane contactor was evaluated. A hot water model system was constructed and inoculated with L. pneumophila at DO concentrations above 0.5 mg/L. Once the model system was colonized, DO levels were incrementally reduced. Water samples were collected each week to evaluate the effect of reducing dissolved oxygen levels when all other conditions favored Legionella amplification. At DO concentrations below 0.3 mg/L, L. pneumophila concentrations were reduced by 1-log over 7 days. Under conditions in the hot water model system, at favorable temperatures and with no residual chlorine disinfectant, L. pneumophila concentrations were reduced by 1-log, indicating growth inhibition by reducing DO levels as the sole control measure. In sections of the model system where DO levels were not lowered L. pneumophila continued to grow. Reducing dissolved oxygen levels in hot water systems of healthcare and other large buildings to control L. pneumophila could also lower the risk of supplemental chemical treatment methods currently in use.
A view of seismic robustness based on uncertainty
Creators: name: Vamvatsikos, Dimitrios
Publisher: name: The University of British Columbia
Year: 2015

description: A simplified view of robustness and redundancy is presented for the seismic assessment and design of structures. It is argued that the topological simplicity of the seismic load, i.e., its highly correlated nature of application for practically every component in all but the ultra-long structures, means that simpler formulations can be devised compared to blast, wave or wind hazards. In that sense, robustness may be considered to express the influence of structural uncertainties on the seismic performance of the structure, in essence showing the available margin of safety subject to material variability. Quantitatively, a pertinent robustness/redundancy index is defined as the ratio of two different estimates of the mean annual frequency (MAF) of exceeding a limit-state of interest, such as global collapse: On the denominator lies the MAF estimate that incorporates all sources of variability while on the nominator is the estimate that neglects structural uncertainties. It is shown that a simple closed form solution is available that directly relates robustness to the dispersion of response due to model parameter uncertainty. As an example, a steel frame where only beams are allowed to yield is shown to be more robust compared to another version where columns become the sacrificial element.

description: Three-dimensional (3D) printing is an emerging and booming industry in Taiwan. Compared to traditional manufacturing, 3D printing has various advantages, such as advanced customization, additive manufacturing, reduced mold opening time, and reduced consumption of precursors. In this study, the real-time monitoring of particulate matter (PM) and total volatile organic compound (TVOC) emissions from various filaments is investigated using fused deposition modeling with material extrusion technology, a liquid-crystal display, a stereolithography apparatus based on vat photopolymerization technology, and binder jetting for occupational settings. An exposure assessment for nearby workers using the 3D printing process was performed, and improvement measures were recommended. Nine 3D printing fields were measured. The generation rate of ultrafine particles ranged from 1.19 × 1010 to 4.90 × 1012 #/min, and the geometric mean particle size ranged from 30.91 to 55.50 nm. The average concentration of ultrafine particles ranged from 2.31 × 103 to 7.36 × 104 #/cm3, and the PM2.5 and PM10 concentrations in each field ranged from 0.74 ± 0.27 to 12.46 ± 5.61 μg/m3 and from 2.39 ± 0.60 to 30.65 ± 21.26 μg/m3, respectively. The TVOC concentration ranged from 0.127 ± 0.012 to 1.567 ± 0.172 ppm. The respiratory deposition (RDUFPs) dose ranged from 2.02 × 1013 to 5.54 × 1014 nm2/day. Depending on the operating conditions, appropriate control and protective measures should be employed to protect workers’ health.

Point-of-Care Devices in Healthcare: A Public Health Perspective
Creators: name: Zarnegar, Armita
Publisher: name: Swinburne

description: Point-of-Care (POC) devices enable medical interventions, such as testing, to be performed near the patient and often by the patient. It has been suggested that the use of POC devices will change medicine from a symptom/diagnosis/treatment endeavor to a monitoring/prediction/prevention exercise. The rate at which this area introduces innovation and discovery is high, although a majority of such devices are currently utilized for screening purposes. This article discusses the public health benefits of POC devices in terms of patient engagement, health inequality, health promotion and their impact on healthcare system. Low-cost screening clinics that use POC devices ultimately help reduce health inequality in developing countries and remote areas. The article also outlines the issues hindering the benefits of using POC such as connectivity, integration and data management, and calibration. Further, it suggests a framework to present and evaluate POC devices used in the healthcare industry. We argue that having such a framework provides a set of measures to evaluate and select POC for various tasks. The scope of this study is limited to medical-grade devices used at home or in clinics, aged care facilities, and hospital settings.

description: Exposure to respirable dust and crystalline silica (SiO2) has been linked to chronic obstructive pulmonary disease, silicosis, cancer, heart disease, and other respiratory diseases. Relatively few studies have measured respirable dust and SiO2 concentrations among workers at brick kilns in low- and middle-income countries. The purpose of this study was to measure personal breathing zone (PBZ) respirable dust and SiO2 concentrations among workers at one brick kiln in Bhaktapur, Nepal. A cross-sectional study was conducted among 49 workers in five job categories: administration, fire master, green (unfired) brick hand molder, green brick machine molder, and top loader. PBZ air samples were collected from each worker following Methods 0600 (respirable dust) and 7500 (respirable crystalline SiO2: cristobalite, quartz, tridymite) of the U.S. National Institute for Occupational Safety and Health. Eight-hour time-weighted average (TWA) respirable dust and quartz concentrations were also calculated. SiO2 percentage was measured in one bulk sample each of wet clay, the release agent used by green brick hand molders, and top coat soil at the brick kiln. The geometric mean (GM) sample and TWA respirable dust concentrations were 0.20 (95% confidence interval [CI]: 0.16, 0.27) and 0.12 (95% CI: 0.09, 0.16) mg/m3, respectively. GM sample and TWA quartz concentrations were 15.28 (95% CI: 11.11, 21.02) and 8.60 (95% CI: 5.99, 12.34) µg/m3, respectively. Job category was significantly associated with GM sample and TWA respirable dust and quartz concentrations (all p < 0.0001). Top loaders had the highest GM sample and TWA respirable dust concentrations of 1.49 and 0.99 mg/m3, respectively. Top loaders also had the highest GM sample and TWA quartz concentrations of 173.08 and 114.39 µg/m3, respectively. Quartz percentages in bulk samples were 16%-27%. Interventions including using wet methods to reduce dust generation, administrative controls, personal protective equipment, and education and training should be implemented to reduce brick kiln worker exposures to respirable dust and SiO2.

description: The relatively low temperatures (~2-4 kK), small radii, and sheer abundance make M dwarfs favorable candidates for planet detection and atmospheric characterization. Current models for the habitable zone are determined by the host star luminosity and rarely include contributions from flaring. Stellar flares, which occur when the coronal magnetic field reorganizes to a lower energy state, release panchromatic radiation which has a significantly higher brightness temperature (~9-20 kK) than the star. The excess ultraviolet contribution has strong implications for observable exoplanetary phenomena such as atmospheric loss and induced photochemistry. Increased magnetic activity on M dwarfs results in energy released during flaring events becoming a notable contributor to the radiation environment. Consequently characterizing the evolution of flare properties is crucial to understand the planetary context that is needed to interpret observations of exoplanet atmospheres. The beta Pictoris moving group (24 +/- 3 Myr) provides an optimal starting point for the analysis of young low mass star flaring rates within the framework of larger flare studies in which effects due to metallicity and age become less pronounced. With >40 viable M dwarf members, including the multi-planet system host AU Mic, we use TESS observations to identify and characterize flare properties of these stars such as total energy and cumulative flare rate. We present an initial analysis of this population and their potential insight into the co-evolution of host stars and associated planets. Work to expand this analysis into other well-populated and observationally accessible moving groups and therefore different ages is ongoing. Results from this study will assist in determining how changes in flare properties over time impact the atmospheric evolution of exoplanets.

description: While planetary collisions are well described by state-of-the-art SPH simulations, the problem of including collisional debris in N-body simulators is far from being solved. Each collision can generate billions of particles ranging from dust to asteroids, and including these into simulations is computationally impracticable. Several solutions have been proposed, the 4 most popular being: the “perfect merging” method, where collisions are assumed to be inelastic; the “fragmentation without debris” method, where fragmentation during collisions is allowed but the fragmented mass is removed from the simulation; the “same mass debris” method, where the fragmented mass is clustered into few bodies with mass usually around one lunar mass; the “unresolved debris” method, where the fragmented mass is included in the simulation as unresolved material that can be accreted by the fully resolved bodies. Each of these methods employs different degrees of approximation that can affect the simulation outcome. In this work we present the results of an homogeneous comparative study aimed at testing how simulations of rocky planets formation are sensitive to the method employed. We used a set of 20 starting setups (similar to the one presented in Burger et al. 2020) and we run simulations with the 4 methods described above, for a total of 80 simulations. For solving collisions, we interpolated within a catalogue of SPH simulations (see Crespi et al. 2021). We tracked two materials: rocky material (basalt) and water (ice). The preliminary results of our simulations are hereby presented.
