An Adaptable Random Forest Model for the Declustering of Earthquake Catalogs

Earthquake catalogs are essential to analyze the evolution of active fault systems. The background seismicity rate, or rate of earthquakes that are not directly triggered by other earthquakes, directly relates to the stressing rate, a crucial quantity for understanding the seismic hazards. Determining the background seismicity rate is challenging because aftershock sequences may dominate the seismicity rate. Classifying these events in earthquake catalogs—known as catalog declustering—is a common practice and most declustering solutions rely on spatiotemporal distances between events, such as the nearest‐neighbor‐distance algorithm, widely used in various contexts. This algorithm assumes that the nearest‐neighbor distance (NND) follows a bimodal distribution related to the background seismicity and to the aftershocks. Constraining these two distributions is crucial to distinguish the aftershocks from the background events accurately. Recent work often uses linear splitting based on the NND, ignoring the potential overlap between the two populations and resulting in a biased identification of background earthquakes and aftershock sequences. We revisit this problem with machine‐learning algorithms. After testing several popular algorithms, we show that a random forest trained with various synthetic catalogs generated by an Epidemic‐Type Aftershock Sequence model outperforms approaches such as k‐means, Gaussian‐mixture models, and support vector machine classification. We apply our model to two different earthquake catalogs: the relocated Southern California earthquake center catalog and the GeoNet catalog of New Zealand. Our model capably adapts to these two different tectonic contexts, highlighting the differences in aftershock productivity between crustal and intermediate‐depth seismicity.

Sonar jamming in the bat-moth arms race

Aaron J. Corcoran SONAR-JAMMING IN THE BAT-MOTH ARMS RACE Dissertation under the direction of William E. Conner, Ph.D. Professor of Biology Bats and moths are an example of a diffuse evolutionary arms race – a situation where groups of prey and predator species evolve increasingly sophisticated means to out-compete the other. Chapter one provides an overview of this arms race. Bats capture night-flying insects using highly sophisticated echolocation and flight. Most macrolepidoptera are eared and bat echolocation calls stimulate evasive flight reactions. Some tiger moths (Lepidoptera: Erebidae, subfamily Arctiinae) also respond to bats with trains of ultrasonic clicks which 1) truthfully or deceitfully warn bats of a distasteful prey, 2) startle bats, or 3) interfere with or jam bat sonar. Evidence is strong for the warning and startle hypotheses, although the startle effect is ephemeral. The jamming hypothesis has not been confirmed to occur in nature. In chapter two I tested the sonar jamming hypothesis using a moth (Bertholdia trigona) that clicks at over 1000% of the rate of other tiger moths that have been studied behaviorally. I pitted tethered B. trigona and silent control moths against naïve, labreared big brown bats (Eptesicus fuscus) in a flight room over seven nights, followed by two nights against B. trigona with ablated tymbal organs. The bats captured control moths 400% more often than clicking B. trigona. Bats ate 78% of silenced B. trigona, refuting the acoustic aposematism hypothesis. Bats failed to habituate to the clicking moths, rendering startle highly unlikely. The pattern of bat capture success matched the predictions of the jamming hypothesis. Additionally, the bat echolocation’s pattern

The empirical data is based on questionnaires, unstructured group interviews and observations during four military activities in Norway. Overall, the study provides an outline regarding attitude, compatibility, effort and performance expectancy for use of mobile information platforms in the military domain.
An Interval Type-2 Fuzzy Analytic Network Process For Prioritizing of Store Plan Alternatives Produced With Ruled Based Design

The widespread use of computer technologies in engineering and architecture provides essential contributions to engineers and architects in solving design problems. The computational design approach, which emerged depending on computer science and design theories and software and hardware technologies, is reflected in today's engineering and architectural works. In this study, store plan alternatives were prioritized by the Interval Type-2 Fuzzy Analytic Network (IT2 FANP) methodology, and the best alternative of store plans was selected. In addition, the results obtained for the four methods were compared. Type-2 Fuzzy Set can reduce the effects of vagueness and uncertainties. These sets make it probable to model uncertainties directly. There are very few studies on the IT2 FANP method for architectural design area in the literature. Our aim is to contribute to the literature by increasing the studies in this field.

Microfabrication and post-CMOS integration techniques for a reconfigurable wafer-sized circuit board

The WaferBoard(tm) rapid prototyping platform for electronic systems is proposed as a tool to help meet today's tight delivery time, performance and reliability constraints. At the core of WaferBoard(tm) is the WaferIC(tm), a wafer-scale reconfigurable CMOS circuit. At the surface of this complex circuit is a sea of identical contacts, any pair of which can be interconnected through a mesh grid network called WaferNet(tm). The user can simply deposit packaged integrated circuits on the smart active surface, and then a complex interconnect pattern between these ICs can be established in a matter of minutes. As is the case with development of any novel technology, design of the platform poses several technical challenges. Some of the postprocessing and integration tasks to be accomplished on the CMOS wafer are laid out hereafter. Firstly TSV etching was studied in depth and optimized to obtain vias of aspect ratio up to 15:1. Then the processing of a 0. 18μm CMOS TestChip fabricated to validate the WaferIC(tm) concept on a 1/100th scale is outlined. Topside processing is then investigated with the characterization of Anisotropic Conductive Films leading to the choice of an ultra-high fiber density Z-Axis film attached in a novel unbonded manner. %%%%Le WaferBoard(tm) de DreamWafer qui permet de prototyper rapidement des systemes electroniques est un outil propose pour repondre aux contraintes de developpent grandissantes de nos jours.

Fictive Motion and Its Rhetorical Effect in Chinese Novels

Fictive motion is to represent stability by motion; it is first put forward by Talmy, who divided the fictive motion into five categories, that is to say, “emanation,” “pattern paths,” “frame-relative motion,” “advent paths,” “access paths,” and “coextension paths. ”. Fictive motion is not only used in English, but also widely used in Chinese, especially in Chinese literary works, in which fictive motion has an intimate relationship with the figure of speech. The use of fictive motion and figure of speech make the works vivid and interesting. This paper intends to discuss the fictive motion and its rhetorical effect in Chinese novels.
Barriers and Motivators for Mosquito Bed Nets Use during Pregnancy in the Middle Belt of Ghana

Malaria in pregnancy is of global health concern. Free distributions of Insect-Repellent Preserved Nets (IRPNs) are introduced in Ghana to protect everyone particularly pregnant women from mosquito bites. This study aims at assessing the barriers and motivators to insecticide bed net use during gestation in the Kintampo Municipality. This study employed a descriptive cross-sectional study that used a mixed methods approach to conduct the study. Multi stage sampling technique was used. Proportionate sampling was used to determine the number of respondents from each facility. Purposive sampling technique was used to select partners of ANC attendees for a focus group discussion. Data was analysed using Stata version 15 and N-Vivo 12. Data triangulation techniques were used to merge the two data sources. Test of association between independent variables and dependent variable (ITN use) was examined using Chi-square test and logistic regression models to determine the strength of the relations. A p-value of ≤0.05 was deemed to be statistically significant. Majority of pregnant women 71.4% sleep under treated insecticides net. Motivators for bed net use were to prevent mosquito bites 228 (83.2%) and to provide privacy 17 (6.2%). Barriers to bed net use were heat 59 (55.7%) and inconvenience in sleeping under the net 4 (3.8%). There is high rate of insect repellent pickled net use amongst antenatal women. Household arrangements as well as bed nets hanging challenges in the room are barriers to net use. Key words: Malaria, mosquito nets, usage, motivators, barriers and pregnancy.
Making teamwork work

This paper explores team assignments as an increasingly common component of many university courses. It argues that a need exists for all instructors, particularly those involved in the teaching of business communication, to develop a multi-faceted teamwork perspective which encompasses every dimension of team assignments. Such a perspective should permeate assignment design, student training, assessment of team process as well as product, self and peer assessment and the individualisation of student scores. Each of these facets is discussed with reference to research literature with a number of practical suggestions provided as exemplars for how to make teamwork work.
Development of a Risk-Factor Model for Predicting Occurrence of Knee Osteoarthritis

This study identified the required risk factors for Knee Osteoarthritis (KOA) patients and formulated a predictive model based on the identified variables. Extensive review of related work was done so as to understand the body of knowledge surrounding musculoskeletal related diseases and to identify knee osteoarthritis as one of the diseases under musculoskeletal condition as well as elicit the risk factors for it, these were validated from medical experts. The model to forecast knee osteoarthritis was formulated comparing four supervised machine learning algorithms namely Naïve Bayes, Multilayer perceptron, C4.5 Decision Tree and Support Vector Machine. The result of the model showed an accuracy of 97.59% considering the 36 initially identified attributes using no feature selection method, the results also showed the minimum number of variables relevant for knee osteoarthritis condition. Further results showed that all identified variables are relevant for effective and efficient development of a prognostic model for knee osteoarthritis. The study concluded that age as the most important variable for KOA and that all 36 identified attributes are relevant for predicting the risk of KOA. Keywords: Knee osteoarthritis, Prognostic Model, Machine learning.
Poverty and Real Exchange Rate: Evidence from Panel Data

The paper explores the relationship between economic policies and poverty by using the dependant economy model framework. Accordingly, it focuses on two variables: the real exchange rate and the absorption, and explores the links between these two variables and poverty. This method has particularly the advantage of addressing model uncertainty. Using the System general method of moments (SY-GMM) estimator (Blundell and Bond, 1998), the paper shows that real exchange rate depreciation favours the poor, provided that income is fairly distributed and institutions are sound.
Informal Caregiving and Its Hidden Cost to National Economy- With a Toronto Case Study

More than eight million Canadians are providing care for their aging family members, relatives, neighbours, or friends. Due to staff shortage, eldercare facilities are also relying on their residents’ families to fill the gap of the care needs. Caregiving responsibilities have forced many employees to take time-off from work or take early retirement, which is a heavy loss of productivity of Canada’s national economy. This study employed a mixed method strategy, and with both qualitative and quantitative data collection methods: interview, focus group discussion, and a questionnaire survey. It shows that Canadians must take time off from work or to leave jobs for providing care to their loved ones, even when they are residing in a long-term care setting. This seemingly private matter is a very public one in the other side of the coin: family caregivers’ lost time in employment is affecting Canada’s national economy significantly. Government should work with stakeholders to develop a national strategy to tackle the issue. COVID-19 outbreak has revealed long-term care institutions’ struggle with severe staff shortage in Canada.
The decline of the herpetofauna populations related to open water resources on Aegean islands using the example of Kythnos

Though naturally rare, wetland biotopes on small Greek islands have great significance for biodiversity there and for migrating animals. Anthropogenic influences are diminishing these habitats, and climate change is accelerating their decline. This is exemplified for Kythnos with reference to the occurrence of the Balkan terrapin (Mauremys rivulata) and the Balkan frog (Pelophylax kurtmuelleri). The hydrologic catchments were searched for their occurrence in late May/early June 2021. Most of the former known populations have disappeared, and those that remain are extremely vulnerable, so that these species are likely to become extinct on
Stress Intensity Factor Measurement of Two-Dimensional Cracks by the Use of Piezoelectric Sensor.

In this paper, a method to measure the stress intensity factor of a two-dimensional crack existing in a member of real structure is presented. The proposed method uses the following properties of piezoelectric materials; (1) isotropic piezoelectric material induces an electric charge which is proportional to the sum of stresses (σx+σy) on the structural member's surface; (2) the electric charge is also proportional to the integral of (σx+σy) in the area where the piezoelectric element is adhered to the structure. In order to obtain the stress intensity factors of Model I and Model II separately, two small pieces of piezoelectric elements are adhered near the crack tip so that the two piezoelectric elements are placed close to each other with the crack tip positioned between the piezoelectric elements. The electric current from the piezoelectric elements are integrated by the integration circuits and the output voltages which are proportional to the electric charge induced in the piezoelectric elements are measured. The stress intensity factors of Model I and Model II of the crack are estimated by the use of the measured output voltages.
Dynamic control for two-link flexible manipulator.

In the near future, many robots will be used in space for extravehicular tasks. Most of these robots will be structurally flxible reflecting the necessity for their light weight. In this paper, dynamic control for a two-link flexible SCARA manipulator, handling a large mass payload, has been studied. For real-time compensation, a simple dynamic model was derived using the static deflection model, to derive the system dynamics equations of a flexible manipulator. To investigate the effectiveness of this model, dynamic analysis was done by simulation and experiments. A two-link flexible SCARA manipulator system was constructed. This manipulator was 1.5 m long and was floating on a plate base using air bearings, handling a 100 kg payload. Its results showed that the model accurately reproduced the state of main deflection. Next, a dynamic control was done using this experimental setup. Its results using this model were compared to results using a rigid model, and the validity of the developed model was demonstrated.
