With development of economy, all industries have undergone earthshaking changes. Various new technologies are starting to be employed in all aspects of life, and graphic design is no exception. The use of computer graphics and image processing technologies in graphic design can substantially improve design efficiency and make graphic design job more convenient to develop. The requirements for the quality of graphic design are higher. Quality inspection has become a necessary step in the production process, in which the detection of graphic design defects is an indispensable and important link. The traditional graphic design defect detection adopts the method of manual visual inspection, which has the disadvantages of poor stability, long consumption time, and high labor cost. As an efficient computer graphics and image processing technology, convolutional neural network has received extensive attention in graphic design defect detection because of its advantages of high speed, efficiency, and high degree of automation. Taking agricultural product packaging as an example, this paper studies application technology for graphic design defect detection with convolutional neural network (CNN). The main contents are as follows: construct the original YOLOv3 network model, input the graphic design images of agricultural product packaging into the network model in batches according to the computing power of the hardware equipment, train the YOLOv3 network, and deeply study and analyze the experimental results. The related improvement techniques are then given, based on the characteristics of agricultural product packaging design faults. The backbone network, multiscale feature map, a priori frame, and activation function of YOLOv3 are improved, and then performance of the improved model is verified by experiments.

The paper presents the main advantages of using the project method during distance work of students when they execute a graphic project in the discipline "Engineering Design Graphics". Students study in the specialty "Fine Arts." It is known that high-quality education can be only when theoretical knowledge can be applied in practice. Therefore, it is the use of the project method in the study of graphic disciplines that can become the basis for the training of design specialists. The use of the project method in the study of graphic disciplines leads to an increase in student activity, the acquisition of teamwork skills, the expansion of students' worldview and the acquisition of professional competencies.The capacity of the project method is confirmed by high-quality student works that were submitted to the competition. In the process of creating the group logo, project participants gained research skills, consolidated their knowledge and skills in graphic description of existing images. The information received in the course "Engineering Design Graphics" allowed the contest participants to qualitatively express their thoughts, demonstrate their creative ideas, and provide the project with high-quality graphic images. The use of the project method allowed teachers to identify the research skills of first-year students, recognize among them those who are able to think independently make non-standard decisions and critically evaluate their work.During the project, students, working in groups, learned to combine the knowledge gained during training, became interested in information about graphic images and methods of their execution, learned to correlate the obtained theoretical material with the solution of the problem of geometric modeling of the emblem of the group. According to the results of the competition, it is possible to draw conclusions that students of the Project Graphics course demonstrated the ability to think independently, make interesting decisions, demonstrated the ability to qualitatively perform two-dimensional graphic images of various complexity when solving various engineering tasks and during design projects.

The article deals with the topical issue of elementary school students’ graphic competence formation using computer-oriented teaching tools. In today’s digital world, where information is presented in various graphic formats, graphic competence is an essential skill for elementary school students. Graphic competence involves the ability to understand, create, and analyze graphics using computer technology. The main aspects of elementary school students’ graphic competence formation through the usage of computer-oriented teaching tools have been determined. Modern approaches to teaching graphic skills and their influence on the educational process are considered. The practical aspects of the implementation of computer-oriented teaching tools for improving students’ graphic competence are highlighted. It is noted that graphic training during primary school education is crucial for students’ future education, as it lays the foundations for the basics of graphic literacy. However, one of the main shortcomings in the educational process related to the study of graphic disciplines is the lack of unity in teaching methods between secondary and higher schools.
It is considered that computer-based teaching tools represent a wide range of technological tools and programs designed to facilitate and facilitate learning through the usage of computers. These tools can be successfully implemented in the educational process at all levels, from primary school to higher education. They cover a wide range of technologies and methodologies, including learning software, interactive exercises, video tutorials, virtual reality, and more. It is determined that augmented reality technology opens up new opportunities for improving elementary school students’ graphic competence. It facilitates the visualization of educational material, ensures the active participation of students in learning, and promotes the graphic content creation. The usage of AR can be a significant step in improving the quality of education and developing the graphic skills of a new generation.

Testo completoAbstract (sommario):
It is becoming increasing important that teachers educate students about social studies in such a way so that students are interested and motivated by what they read. So often the curriculum is bombarded with physically heavy, incomprehensible, and traditional textbooks. Based upon the need for extensions to the social studies textbooks, my goal to establish a guideline for selecting quality graphic novels fitted for elementary social studies instruction. Therefore, my study will attempt to answer the question: What is an effective means of determining quality graphic novels? Following my adaptation and creation of rubrics established for determining the needs and qualities of graphic novels, I was able to establish and analyze several social studies content related graphic novels appropriate for the elementary social studies curriculum. This investigation into social studies graphic novels provided 18 graphic novels for possible use in the elementary social studies curriculum, 5 of which were deemed quality via the established rubrics. Furthermore, the investigation proved that the books deemed quality provided more than what was established as necessary within the rubrics. The additional information found within those texts was referred to as a postlude. One strong conclusion from this study is the large void of graphic novels that teachers might link with the social studies curriculum so as to enhance elementary social studies instruction.B.S.

Testo completoAbstract (sommario):
This is a bachelor thesis on how a group of Graphic Design and Communications (GDK) students at Linköping University evaluates aesthetic graphic quality. The aim of the thesis is to study how the students express themselves, what values the evaluation is based upon and the origin of these values. The purpose is also to look into the significance of possible mutual values, from a sociologic perspective. This essay is based upon sociological theories concerning group socialization and good taste. Further, theory on the subject of aesthetics is presented, and how the terms of good and bad taste have been used in art and design. The data, which make up the result, is mainly from two focus groups, but also from a participant observation and the follow-up questions which were sent out to the participants of the focus groups. The result shows that the participants often primarly judge the aestethic quality on whether the typography, colours and images of the material sends out a clear message. The aesthetic impression is therefor affected by function. Though, this is not the case when the participants leave their role as a designer. With a position taken outside the education, they can justify their aestethic opinion differently. The result also shows that a clean idiom with its roots in the functionalistic aesthetic is a norm, and that this partly descend from an influental guest lecturer. The participants also have the opinion that they, as designers, is expected to appreciate a certain aesthetic but also to know what is ”ugly”. They mean that these are common opinions among designers generally and not only within GDK. The students sometimes consider these opinions on aesthetics as an obstacle when it comes to develop their own manner, but at the same time they believe it is good for the unity of the group. To be able to motivate an aesthetic position with arguments based on function is also important in the contact of clients, which indicates that the dominance of the functionalistic aesthetic has to do with the economic aspect of graphic design.Denna kandidatuppsats handlar om hur en grupp studenter på programmet Grafisk Design och Kommunikation (GDK) på Linköpings Universitet bedömer estetisk grafisk kvalitet. Syftet är att undersöka hur studenterna uttrycker sig, vilka värderingar som bedömningen grundar sig i och varifrån dessa kommer. Syftet är också att undersöka vad eventuella kollektiva värderingar har för betydelse ur ett sociologiskt perspektiv. Uppsatsen utgår ifrån sociologiska teorier kring gruppsocialisation och god smak. Vidare presenteras teori kring ämnet estetik, liksom hur begreppen god och dålig smak har används inom konst och design. Det insamlade materialet som utgör resultatet är huvudsakligen hämtat från två fokusgrupper, men också från en deltagande observation samt ett antal följdfrågor till deltagarna i fokusgrupperna. Resultatet visar att deltagarna ofta bedömer den estetiska kvaliteten i första hand efter huruvida det grafiska materialets typografi, färger och bilder gör det lätt att ta till sig budskapet det är avsett att förmedla. Det estetiska intrycket är således påverkat av funktionen. Detta gäller dock inte om deltagarna kliver ur sin roll som designers, då de kan motivera sitt estetiska ställningstagande med en annan position de kan inta utanför utbildningen. Resultatet visar också att deltagarna anser att ett avskalat formspråk med funktionalistiska rötter har blivit norm på utbildningen, och att detta till viss del beror på en inflytelserik gästföreläsare de haft under årskurs ett. Deltagarna anser också att de som designers förväntas uppskatta en viss sorts estetik men också veta vad som är ”fult”. De menar att detta är uppfattningar som finns bland designers i allmänhet och inte bara inom utbildningen. Dessa uppfattningar kring estetik anser studenterna ibland är ett hinder för att utveckla en egen stil som formgivare, samtidigt som de skapar en sammanhållning inom gruppen. Att kunna motivera ett estetiskt ställningstagande med funktionella argument är dessutom viktigt vid kundkontakter, vilket tyder på att den funktionalistiska estetikens dominans kan ha att göra med den ekonomiska aspekten av grafisk design.

With a background in ceramics and graphic designI have developed my thoughts about craft as a combination of verbal and nonverbal communication, but in textiles. With the written word as one of my main materials this project looks into class and material hierarchies filtered through autofictivestories from my life. This paper explores themes that impact my decisions in the making process, choosing materials, motifs, texts and words, politics and poetry. It deals with all the information I push into patchworking, shirring, tufting and sculpting textiles, with the goal to paint a picture of an often unwanted section of society. To discuss this I have chosen references dealing with sloppy craft, text based art, graffiti and craft traditions, in a mix with news articles and economy. Through all parts of the project I am on balancing line between chaos and perfection, truth and fiction.

Testo completoAbstract (sommario):
Depuis quelques années, nous assistons à une véritable explosion de la production de données dans de nombreux domaines, comme les réseaux sociaux ou le commerce en ligne. Ce phénomène récent est renforcé par la généralisation des périphériques connectés, dont l'utilisation est devenue aujourd'hui quasi-permanente. Le domaine aéronautique n'échappe pas à cette tendance. En effet, le besoin croissant de données, dicté par l'évolution des systèmes de gestion du trafic aérien et par les événements, donne lieu à une prise de conscience sur leur importance et sur une nouvelle manière de les appréhender, qu'il s'agisse de stockage, de mise à disposition et de valorisation. Les capacités d'hébergement ont été adaptées, et ne constituent pas une difficulté majeure. Celle-ci réside plutôt dans le traitement de l'information et dans l'extraction de connaissances. Dans le cadre du Visual Analytics, discipline émergente née des conséquences des attentats de 2001, cette extraction combine des approches algorithmiques et visuelles, afin de bénéficier simultanément de la flexibilité, de la créativité et de la connaissance humaine, et des capacités de calculs des systèmes informatiques. Ce travail de thèse a porté sur la réalisation de cette combinaison, en laissant à l'homme une position centrale et décisionnelle. D'une part, l'exploration visuelle des données, par l'utilisateur, pilote la génération des règles d'association, qui établissent des relations entre elles. D'autre part, ces règles sont exploitées en configurant automatiquement la visualisation des données concernées par celles-ci, afin de les mettre en valeur. Pour cela, ce processus bidirectionnel entre les données et les règles a été formalisé, puis illustré, à l'aide d'enregistrements de trafic aérien récent, sur la plate-forme Videam que nous avons développée. Celle-ci intègre, dans un environnement modulaire et évolutif, plusieurs briques IHM et algorithmiques, permettant l'exploration interactive des données et des règles d'association, tout en laissant à l'utilisateur la maîtrise globale du processus, notamment en paramétrant et en pilotant les algorithmes.

Testo completoAbstract (sommario):
L’utilisation des technologies immersives destinées à des fins thérapeutiques est pratiquée depuis plusieurs années. Si ces techniques furent d’abord appliquées aux troubles phobiques, elles se sont peu à peu étendues vers d’autres pathologies telles que la schizophrénie et les troubles alimentaires. Les travaux existants concernant l’utilisation de la réalité virtuelle (RV ) pour le traitement de troubles alimentaires se concentrent sur deux problématiques : (1) la correction de la distorsion de la représentation que le patient se fait de lui-même et pour laquelle la RV l’aide à corriger cette représentation erronée via l’incarnation ou la visualisation d’un avatar ; (2) l’utilisation de l’environnement avec des éléments déclencheurs de la pathologie (ex., nourriture) dans le but de mieux caractériser les symptômes et de réaliser une thérapie d’exposition aux signaux. Le premier objectif de la thèse est de proposer et d’évaluer un environnement immersif induisant les condition de craving alimentaire (besoin irrépressible de consommation d’un produit associé à une recherche compulsive), le tout chez les personnes atteintes de bulimia nervosa ou d’hyperphagie boulimique, comparativement à des personnes saines appariées. Le développement de cet environnement repose sur un travail de design collaboratif, dans lequel l’utilisation d’un environnement immersif avec un scénario scripté et semi-guidé, avec des stimuli multi-modaux, constitue un élément novateur. La caractérisation de l’environnement s’effectue sur l’actuelle mesure de référence du craving alimentaire en RV soit une auto-évaluation par échelle verbale simple dont nous étudions les variations durant l’exploration du scénario avant et après chaque pièce virtuelle d’exposition, ainsi que son association à l’anxiété induite par l’exploration aux mêmes moments. De plus, certains paramètres physiologiques ayant pu être associés au craving des troubles addictifs sont mesurés aux différents moments d’évaluation (variabilité de fré- quence cardiaque (variations des intervalles entre chaque battement de coeur) et activité électrodermale (activité bioélectrique cutanée physiologique)). Enfin, nous utilisons également des méthodes de phénotypage, basées sur des questionnaires d’auto-évaluation, qui visent à mettre en évidence des dimensions comportementales et émotionnelles qui peuvent être des facteurs propices au déclenchement des crises. Par ailleurs, dans le cadre des études sur l’envie de manger, la qualité visuelle apparaît comme un paramètre majeur qu’il faut contrôler afin de proposer des environnements iv adaptés aux contraintes d’expérience utilisateur ainsi qu’aux contraintes techniques. Le second objectif de la thèse est d’étudier comment la qualité visuelle des stimuli alimentaires influence le désir de manger dans un environnement en réalité virtuelle. Cette évaluation s’effectue sur des personnes non pathologiques, avec des visuels alimentaires de qualité graphique variable et classés au préalable selon une métrique entraînée sur un apprentissage profond capable de délivrer un score moyen de qualité graphiqueThe use of immersive technologies for therapeutic purposes has been practiced for several years. While these techniques were initially applied to phobic disorders, they have gradually expanded to other disorders such as anxiety, schizophrenia and eating disorders. Existing research on the use of virtual reality (VR) for the treatment of eating disorders focuses on two issues : (1) correcting the distortion of the patient’s self-representation, where VR helps correct this erroneous representation through embodiment or visualization of an avatar (2) using the environment with triggering elements of the pathology (e.g., food) to better characterize symptoms and conduct exposure therapy to these cues. The first objective of the thesis is to propose and evaluate an immersive environment inducing conditions of food craving (irresistible urge to consume a product associated with compulsive seeking) in individuals with bulimia nervosa or binge-eating disorder, compared to matched healthy subjects. The development of this environment is based on collaborative design work, in which the use of multi-modal stimuli is an innovative element. The characterization of the environment is based on the current reference measure of food craving in VR, which is a self-assessment using a simple verbal scale. We study variations during the exploration of the scenario before and after each virtual exposure, as well as its association with anxiety induced by the exploration at the same moments. Additionally, certain physiological parameters previously associated with cravings in addictive disorders are measured at different evaluation points (heart rate variability and electrodermal activity). Finally, we also use phenotyping methods based on self-assessment questionnaires to highlight behavioral and emotional dimensions that may contribute to triggering episodes. Moreover, in the context of studies on the desire to eat, visual quality emerges as a major parameter that needs to be controlled to offer environments suitable for user experience constraints and technical limitations. The second objective of the thesis is to study how the visual quality of food stimuli influences the desire to eat in a virtual reality environment. This evaluation is performed on non-pathological individuals, with food visuals of varying graphic quality, pre-classified according to a deep learning-trained metric capable of delivering an average graphic quality score

Papers are the most commonly used substrates. A printable paper must have certain properties. These properties include surface smoothness, air permeability, surface energy, colour of the paper, opacity, whiteness, light fastness, gloss, and coefficient of elongation under force. In addition, a good printable paper should not allow ink to pass between its two surfaces. After the papers are produced, they are subjected to surface treatments in order to improve the above-mentioned properties and to provide extra specification. Surface treatments include calendering, surface sizing and coating processes. While filling the recesses and protrusions on the surface with the coating process, the paper's affinity for the ink is increased, and the penetration of the ink to the other surface of the paper is prevented. In the coating process basically, a filler is dispersed in a binder. In this study, it is aimed to obtain the highest quality and most printable paper by changing the type of binder used in the coating. In this study, equal amount (5% w/w) titanium dioxide filler was used in all coating formulations. In coating formulations; cationic starch, hydroxy ethyl cellulose and polyvinyl alcohol polymers were used as binders. Binder amounts are adjusted according to optimum viscosity. The obtained coating formulations were coated on the paper surface with a laboratory type coating device. Colour, gloss, surface smoothness, air permeability, surface energy and surface morphology of the coated papers were determined. It was printed with magenta offset printing ink on three different types of paper coated with different binders, using the IGT C1 offset printability test device, under 400 N/m2 pressure printing conditions. Colour and gloss measurements of the prints were made. As a result; It was determined that three different binders improved the printability parameters.

The Global Ocean Data Analysis Project (GLODAP) is a synthesis effort that provides high-quality, quality-controlled ocean biogeochemical bottle data with annual-updates, playing a crucial role in advancing our understanding of the Earth's oceans and their complex biogeochemical processes. This deliverable covers the GLODAP annual updates under the EuroSea funding, as well as the automatization of the quality control process of the data. Under the EuroSea funding, GLODAP has received three updates (GLODAPv2.2020, GLODAPv2.2021 and GLODAPv2.2022) with a total number of 245 cruises added, and in addition, a new version release (GLODAPv3) is planned. These updates were possible as a result of the large degree of automatization of the quality control process that ensures the accuracy of the data. The core of the quality control process is the crossover analysis that is currently performed via the 2nd QC Matlab toolbox from Lauvset and Tanhua (2015). However, following Eurosea’s vision of a user-focused, truly interdisciplinary, and responsive European ocean observing and forecasting system, this deliverable aims to migrate from the Matlab toolbox to an online web application based on the open-source software Django and Python. This will allow the user to simply upload the data file to be quality controlled and the web application performs the secondary quality control through the deep water crossover analysis just as in Matlab, and offers similar graphics for visualization. Because the crossover analysis is partially automated on this online tool, the users do not need to possess any programming knowledge in order to quality control their data. In addition, this online tool can be part of a fully automated GLODAP quality control process, without need for manual intervention. (EuroSea Deliverable, D4.12)

Testo completoAbstract (sommario):
30 Day Hospital Readmission Rates, Frequencies, and Heart Failure Classification for Patients with Heart Failure Background Congestive heart failure (CHF) is the leading cause of mortality, morbidity, and disability worldwide among patients. Both the incidence and the prevalence of heart failure are age dependent and are relatively common in individuals 40 years of age and older. CHF is one of the leading causes of inpatient hospitalization readmission in the United States, with readmission rates remaining above the 20% goal within 30 days. The Center for Medicare and Medicaid Services imposes a 3% reimbursement penalty for excessive readmissions including those who are readmitted within 30 days from prior hospitalization for heart failure. Hospitals risk losing millions of dollars due to poor performance. A reduction in CHF readmission rates not only improves healthcare system expenditures, but also patients’ mortality, morbidity, and quality of life. Purpose The purpose of this DNP project is to determine the 30-day hospital readmission rates, frequencies, and heart failure classification for patients with heart failure. Specific aims include comparing computed annual re-admission rates with national average, determine the number of multiple 30-day re-admissions, provide descriptive data for demographic variables, and correlate age and heart failure classification with the number of multiple re-admissions. Methods A retrospective chart review was used to collect hospital admission and study data. The setting occurred in an urban hospital in Memphis, TN. The study was reviewed by the UTHSC Internal Review Board and deemed exempt. The electronic medical records were queried from July 1, 2019 through December 31, 2019 for heart failure ICD-10 codes beginning with the prefix 150 and a report was generated. Data was cleaned such that each patient admitted had only one heart failure ICD-10 code. The total number of heart failure admissions was computed and compared to national average. Using age ranges 40-80, the number of patients re-admitted withing 30 days was computed and descriptive and inferential statistics were computed using Microsoft Excel and R. Results A total of 3524 patients were admitted for heart failure within the six-month time frame. Of those, 297 were re-admitted within 30 days for heart failure exacerbation (8.39%). An annual estimate was computed (16.86%), well below the national average (21%). Of those re-admitted within 30 days, 50 were re-admitted on multiple occasions sequentially, ranging from 2-8 re-admissions. The median age was 60 and 60% male. Due to the skewed distribution (most re-admitted twice), nonparametric statistics were used for correlation. While graphic display of charts suggested a trend for most multiple re-admissions due to diastolic dysfunction and least number due to systolic heart failure, there was no statistically significant correlation between age and number or multiple re-admissions (Spearman rank, p = 0.6208) or number of multiple re-admissions and heart failure classification (Kruskal Wallis, p =0.2553).

Monitoring water quality of small inland lakes and reservoirs is a critical component of USACE water quality management plans. However, limited resources for traditional field-based monitoring of numerous lakes and reservoirs that cover vast geographic areas often leads to reactional responses to harmful algal bloom (HAB) outbreaks. Satellite remote sensing methodologies using HAB indicators is a good low-cost option to traditional methods and has been proven to maximize and complement current field-based approaches while providing a synoptic view of water quality (Beck et al. 2016; Beck et al. 2017; Beck et al. 2019; Johansen et al. 2019; Mishra et al. 2019; Stumpf and Tomlinson 2007; Wang et al. 2020; Xu et al. 2019; Reif 2011). To assist USACE water quality management, we developed an ESRI ArcGIS Pro desktop software toolbox (waterquality for ArcGIS Pro) that was founded on the design and research established in the waterquality R software package (Johansen et al. 2019; Johansen 2020). The toolbox enables the detection, monitoring, and quantification of HAB indicators (chlorophyll-a, phycocyanin, and turbidity) using Sentinel-2 satellite imagery. Four tools are available 1) to automate the download of Sentinel-2 Level-2A imagery, 2) to create stacked image with options for cloud and non-water features masks, 3) to apply water quality algorithms to generate relative estimations of one to three water quality parameters (chlorophyll-a, phycocyanin, and turbidity), and 4) to create linear regression graphs and statistics comparing in situ data (from field-based water sampling) to relative estimation data. This document serves as a user's guide for the waterquality for ArcGIS Pro toolbox and includes instructions on toolbox installation and descriptions of each tool's inputs, outputs, and troubleshooting guidance.

Testo completoAbstract (sommario):
Riprap rock and aggregates are commonly used in various engineering applications such as structural, transportation, geotechnical, and hydraulic engineering. To ensure the quality of the aggregate materials selected for these applications, it is important to determine their morphological properties such as size and shape. There have been many imaging approaches developed to characterize the size and shape of individual aggregates, but obtaining 3D characterization of aggregates in stockpiles at production or construction sites can be a challenging task. This research study introduces a new approach based on deep learning techniques that combines three developed research components: field 3D reconstruction procedures, 3D stockpiles instance segmentation, and 3D shape completion. The approach is designed to reconstruct aggregate stockpiles from multiple images, segment the stockpile into individual instances, and predict the unseen sides of each instance (particle) based on the partially visible shapes. The approach was validated using ground-truth measurements and demonstrated satisfactory algorithm performance in capturing and predicting the unseen sides of aggregates. For better user experience, the integrated approach has been implemented into a software application named “I-RIPRAP 3D,” with a user-friendly graphical user interface (GUI). This stockpile aggregate analysis approach is envisioned to provide efficient field evaluation of aggregate stockpiles by offering convenient and reliable solutions for on-site quality assurance and quality control tasks of riprap rock and aggregate stockpiles. This document provides information for users of the I-RIPRAP 3D software to make the best use of the software’s capabilities.

Ultrasonic flow meters, especially those that exploit multiple paths to achieve higher accuracies, are capable of extensive self-diagnosis. Each ultrasonic meter manufacturer has tended to devel-op diagnostic tools specific to his particular device. This has led to a confusing mix of offerings that are not transportable between meters and whose names and interpretations are not always consistent. The focus of this effort has been to examine four areas that yield information indicative of both the health of the meter and the quality of the measurements it is providing: (1) the meter design and how this impacts the individual diagnostics, (2) the timing aspects of the measurement, (3) the indicators of transducer performance and (4) the observed velocity profile characteristics. This work extends the previous analysis of Daniel and Instromet (Elster) ultrasonic meters to in-clude Sick and Krohne meters. It also updates the Daniel and Instromet information and looks at graphical displays that help with condition based monitoring.

Testo completoAbstract (sommario):
Regional-scale lake sediment surveys have been successfully used since the 1970s as a means for reconnaissance geochemical exploration. Lake sediment sampling is typically performed in areas with a lack of streams and an overabundance of small-sized (=5 km across) lakes. Lake sediments are known to have major, minor and trace element concentrations that reflect the local geology. Overall, lake sediment surveys are planned and conducted following four distinct stages: 1) background research, 2) orientation survey, 3) regional survey, and 4) detailed survey. At the Geological Survey of Canada, samples are usually collected from a helicopter with floats. Sample density ranges from 1 sample per 6 - 13 km2. Samples are collected from the centre of the lake using a gravity torpedo sampler which corresponds to a hollow-pipe, butterfly bottom-valved sampler attached by a rope to the helicopter. Collected sediment samples are then placed in labelled bags and left to air dry. Detailed field notes and additional samples (field duplicates), for the purpose of an adequate quality assurance and quality control program, are also taken. Samples are then milled and sent to analytical laboratories for element determination. Commonly used analytical methods include: X-ray fluorescence (XRF), atomic absorption spectroscopy (AAS), inductively coupled plasma-atomic emission spectrometry (ICP-AES) and -mass spectrometry (ICP-MS), instrumental neutron activation analysis (INAA), and/or determination of volatile compounds and organic carbon using Loss on Ignition (LOI). Analytical data is first evaluated for quality (contamination, accuracy and precision). Numerous options for the analysis of lake sediment data exist, ranging from simple basic element concentration maps and statistical graphical displays together with summary statistics, to employing multivariate methodologies, and, more recently, using machine learning algorithms. By adopting the set of guidelines and examples presented in this manual, scientific researchers, exploration geologists, geochemists and citizen scientists will be able to directly compare lake sediment datasets from anywhere in Canada.

Gridded GIS maps are used to present broad-brush conditions across the region for each month. This regional presentation is compared to detailed data from Remote Automated Weather Stations (RAWS), weather stations in Global Historical Climatology Network (GHCN), and data from USGS stream gages. Prior to analysis, a set of data quality control checks were performed by the authors in accordance with an established National Park Service protocol (Rocky Mountain Climate Working Group 2010). Key points summarizing calendar year 2020 are presented as bullets in the Conclusion section at the end of the report. There was significant spatial and month to month variability in the data that provided exceptions to these generalizations, so an examination of the regional maps is key to understanding the climatic patterns for 2020.
