Résumé :
Summary Background: 3D modelling in orthodontics is becoming an increasingly widespread technique in practice. One of the significant questions already being asked is related to determining the precision of the scanner used for generating surfaces on a 3D model of the jaw. Materials and methods: This research was conducted by generating a set of identical 3D models on Atos optical 3D scanner and Lazak Scan laboratory scanner, which precision was established by measuring a set of orthodontic parameters (54 overall) in all three orthodontic planes. In this manner we explored their precision in space, since they are used for generating spatial models – 3D jaws. Results: There were significant differences between parameters scanned with Atos and Lazak Scan. The smallest difference was 0.017 mm, and the biggest 1.109 mm. Conclusion: This research reveals that both scanners (Atos and Lazak Scan), which belong to general purpose scanners, based on precision parameters can be used in orthodontics. Early analyses indicate that the reference scanner in terms of precision is Atos.

Résumé :
This article concerns the research of the HUBO full-body scanner, which includes the analysis and selection of the scanner’s geometrical parameters in order to obtain the highest possible accuracy of the reconstruction of a human figure. In the scanner version analyzed in this paper, smartphone cameras are used as sensors. In order to process the collected photos into a 3D model, the photogrammetry technique is applied. As part of the work, dependencies between the geometrical parameters of the scanner are derived, which allows to significantly reduce the number of degrees of freedom in the selection of its geometrical parameters. Based on these dependencies, a numerical analysis is carried out, as a result of which the initial values of the geometrical parameters are pre-selected and distribution of scanner cameras is visualized. As part of the experimental research, the influence of selected scanner parameters on the scanning accuracy is analyzed. For the experimental research, a specially prepared dummy was used instead of the participation of a real human, which allowed to ensure the constancy of the scanned object. The accuracy of the object reconstruction was assessed in relation to the reference 3D model obtained with a scanner of superior measurement uncertainty. On the basis of the conducted research, a method for the selection of the scanner’s geometrical parameters was finally verified, leading to the arrangement of cameras around a human, which guarantees high accuracy of the reconstruction. Additionally, to quantify the results, the quality rates were used, taking into account not only the obtained measurement uncertainty of the scanner, but also the processing time and the resulting efficiency.

Résumé :
This paper presents the comparative evaluation of multiple compact and lightweight 2D laser scanners for their possible backpack based scanning and mapping applications. These scanners include Hokuyo URG-04LX, Slamtec RPLidar A1-M8 and Hokuyo UTM-30LX-EW scanners. Since the technical datasheets provide general information and limited working details, this research presents a thorough study on the performance of each scanner related explicitly to indoor mapping operations. A series of scanning experiments have been performed for the characterization of each scanner using statistical analysis. During the testing, all the scanning data has been recorded using Robot Operating System (ROS) and then computed in offline processing. In initial tests, each scanner’s drift effect on range measurements has been tested and presented in the relevant section of the paper. In continuation, the effect of various scanning distances on measurement accuracy has been evaluated and discussed. Later the impact of various materials typically found in indoor vicinities and their respective properties of color and smoothness have been tested and provided in the paper. Finally, a Kalman Filtering based mathematical formulation has been utilized to calibrate each scanner and to reduce the measuring uncertainties as observed in various tests for each scanner.

Résumé :
Digitization of natural history collections for specimen accessibility, research, and posterity has been a major push in museums over the past decade. One increasingly common form of specimen digitization is three-dimensional (3-D) surface scanning. There are numerous 3-D scanners on the market, including visible light and laser surface scanners. However, mobility of the scanning device, mesh resolution, and texture fidelity are among the most prominent issues facing regular implementation of 3-D scanning procedures for research purposes. Morphometrics research involving the digitization of Xiphactinus at the Sternberg Museum of Natural History (FHSM) using a Creaform Go!SCAN 50 visible light 3-D surface scanner has necessitated the development of a workflow using this 3-D scanner and the associated VXelements software. This workflow maximizes model quality with minimal loss of speed or efficiency when scanning numerous specimens. Major components of this workflow include proper use of positioning targets, appropriate merging of multiple specimen scans, and how to perform post-processing on models without sacrificing model resolution or texture. The primary benefit of the Creaform 3-D scanner is hardware mobility, allowing for use on large exhibited specimens or digitizing specimens during research trips. Shortcomings include relatively low mesh resolution, (bottoming out at 0.5 mm), difficulty scanning highly complex structures, and low texture fidelity of scanned models. However, texture fidelity can be improved through use of the free software, Meshlab, by overlaying high-quality stacked photographs onto the 3-D mesh. Incorporating Meshlab texture overlays into the workflow allows for the production of digital models with improved color and textural data – ideal for accurate visualization of specimens in 3-D viewers for educational outreach and online databases. While not perfect for all applications, the Creaform 3-D scanner allows for rapid digitization of specimens in an increasingly digital collections environment, and is sufficient for some research applications. The workflow established at the FHSM can serve as a framework for other institutions to use the Creaform 3-D scanner to best suit their digitization needs.

Résumé :
Abstract Background High-resolution structural MRI has been widely used in clinical research to detect and quantify subtle brain changes in patient populations. Findings from prospective, longitudinal studies show structural brain abnormalities as well as progressive gray matter changes over time in individuals at clinical high risk for psychosis compared to healthy subjects. In recent years, research in this field has seen an increase in multicentre neuroimaging projects, such as EU-GEI, PSYSCAN, PRONIA and NAPLS. Additional sources of variance, alongside known technological and biological factors, may be introduced when MRI images are acquired and combined from different sites. It is imperative for longitudinal multicentre studies to determine the accuracy of quantitative MRI measurements and account for systematic differences both between scanners and across scanning sessions. This is particularly true within psychosis research where morphometric changes as small as 3% or less are expected. Methods Six healthy participants were scanned on four separate occasions over a two-month period at King’s College London; twice on a GE SIGNA HDx 3T scanner used locally in the EU-GEI High Risk Study and twice on a GE MR750 3T scanner used locally in the PSYSCAN study. Both scanners implemented the ADNI-2 T1 protocol which is used globally across the EU-GEI and PSYSCAN consortia. Structural imaging data was segmented using the FreeSurfer 6.0 longitudinal pipeline. Intraclass correlation coefficients (ICCs) with a two-way mixed effects model of absolute agreement were calculated to assess intra- and inter-scanner reliability of brain morphometry. For volumetric studies, ICC values greater than 0.9 indicate ‘excellent’ reliability. Reliability analyses of key regions implicated in psychosis included gray matter volume estimates of the hippocampus, insula, lateral ventricle, orbitofrontal cortex and anterior cingulate cortex, and average cortical thickness measurements of the whole brain, parahippocampus and superior frontal cortex. Results Gray matter volume estimates of all structures yielded ‘excellent’ reliability for both intra-scanner (ICCs of 0.979 – 0.998) and inter-scanner analyses (ICCs of 0.976 – 0.999). Intra-scanner reliability for mean cortical thickness measurements was ‘excellent’ for right total cortex, resulting in an ICC of 0.901, but otherwise ‘good’ for left and total cortex, parahippocampus, superior frontal cortex (ICCs of 0.754 – 0.875). Inter-scanner reliability for mean cortical thickness estimates were most variable across the brain structures. Here, results demonstrated ‘excellent’ reliability for the parahippocampus and left total cortex (ICCs of 0.907 – 0.965), ‘good’ for total cortex (ICC of 0.835), ‘moderate’ for right total cortex, right and total superior frontal cortex (ICCs of 0.520 – 0.676), and ‘poor’ for the left superior frontal cortex which produced an ICC of 0.470. Overall, mean cortical thickness estimates of the superior frontal cortex from two different MR scanners showed the least reliability. Discussion Results confirmed highly reliable estimates for gray matter volumes in all brain structures, both from images acquired within the same scanner and across two different scanners. However, the findings indicated increased variability of mean cortical thickness estimates, particularly between scanners, which should be considered when interpreting study findings. Multicentre structural neuroimaging within the field of psychosis is becoming more common and it must be acknowledged that combining MRI data in multicentre studies will contribute additional sources of variance and potential bias with certain brain regions affected more than others.

The article presents methods of collecting raw datasets in the form of a point-cloud using a low-cost ground-based laser scanner FabScan. As part of the research work 3D scanner from an open source FabLab project was constructed. In addition, the results for the analysis of the geometry of the point clouds obtained by using a low-cost laser scanner were presented. Also, some analysis of collecting data of different structures (made of various materials such as: glass, wood, paper, gum, plastic, plaster, ceramics, stoneware clay etc. and of different shapes: oval and similar to oval and prism shaped) have been done. The article presents two methods used for analysis: the first one - visual (general comparison between the 3D model and the real object) and the second one - comparative method (comparison between measurements on models and scanned objects using the mean error of a single sample of observations). The analysis showed, that the low-budget ground-based laser scanner FabScan has difficulties with collecting data of non-oval objects. Items built of glass painted black also caused problems for the scanner. In addition, the more details scanned object contains, the lower the accuracy of the collected point-cloud is. Nevertheless, the accuracy of collected data (using oval-straight shaped objects) is satisfactory. The accuracy, in this case, fluctuates between ± 0,4 mm and ± 1,0 mm whereas when using more detailed objects or a rectangular shaped prism the accuracy is much more lower, between 2,9 mm and ± 9,0 mm.

Résumé :
The world has recently witnessed the widespread of 3D printing technology. In the shadow of this development a new means of freezing time was born: 3D figurines. A 3D figurine is a mini version of oneself; a little sculpture manufactured by 3D Printers. These 3D figurines are sold for a profit by so called 3D Print Stores to consumers. For the production of such a 3D figurine one needs 3D Body Scanners. It is from the perspective of a producer of 3D Body Scanners that this master thesis was written. The objective was to establish whether or not the company should tap into that new market segment of 3D Print Stores. Furthermore a market entry strategy was to be developed. Thus a marketing research study was performed. For the analysis of the market segment primary and secondary data was scrutinized, which was gathered through expert interviews and desktop research. The primary scope of the study was limited to Germany. Overall the market segment proved to be promising, as consumers regard 3D figurines as a more sophisticated alternative to a digital photo. Competition is currently low, but the threat of new players entering the segment is high. Thus a market entry strategy was elaborated that suggests tapping into the market as fast as possible; thereby obtaining a first mover advantage and pre-empting market space. Furthermore a differentiation strategy was proposed to shield against growing competition.

Résumé :
In order to stay competitive and to be the first choice for customers in a world driven by a high level of competitive advantage, it is important for companies to stay ahead of the competition by conducting thorough market research. Even if this tends to be the case, many products still fail when reaching the market, leaving companies with great losses. The reason for this could be that the development of existing research methods has stagnated, or that they simply lack the ability to find the true answer as to what intentions underlie consumer’s decision making when shopping. Many believe that a new method is desired in order to get a better picture of what customers really think. As a solution to the problem, researchers are using a mix of neuroscience and marketing in order to get into the customers minds. Therefore, this study seeks to create knowledge about the new emerging trend called neuromarketing and its potential as a complement or substitute to surveys, interviews and focus groups. In order to achieve this purpose, relevant theory was collected and compared to the empirical data from focus group studies that were conducted. Findings show that scanning customers’ brains, for now, cannot fully substitute surveys, interviews or focus groups, since each have their own investigational characteristics. This could although change as neuromarketing still is in an early development stage and researchers believe that the method has good future potential. Although neuromarketing cannot be seen as a substitute for now, it still has its advantages compared to surveys, interviews and focus groups. We therefore see that scanning of the brain could be used as a sufficient complement to the other methods through triangulation if companies can afford it.

This study aims to optimize the tissue embedding machine as well as the high-throughput biomedical slide scanner. Regarding the optimization of the tissue embedding machine, this study improves the drawbacks of the prototype machine, such as: improving the design of the drilling mechanism, adjusting the drilling method for tissue embedding machine, utilizing the torque control and PI control, so as to enhance the drilling yield rate. With regard to the optimization of high-throughput biomedical slide scanner, the scanned images could become clearer through the focus calibration technology, and the capability that the area to be scanned could be recognized was added in the slide scanner, so that the scan efficiency of the slide scanner could be increased. About the scanned image reconstruction, this study developed the image reconstruction methods form 2D to 3D, to provide a tool to verify the wear for tissue slicing.

Résumé :
In the last decades, ultrasound imaging systems have become more and more popular thanks to their capability to investigate tissues in safe, cost effective, and non-invasive way. Their role in diagnostic imaging has become fundamental in several medical specialties, thanks also to the introduction of advanced echographic systems fostered by the efforts of several research laboratories around the world. Such efforts are more frequently based on the use of special research scanners, characterized by flexible hardware and programmable software and firmware. These features have been demonstrated ideal for the implementation and test of new methods, such as high frame-rate (HFR) imaging, color flow imaging (CFI), vector Doppler imaging, and 3 D imaging. Especially HFR and 3 D imaging have recently attracted great interest, but they are technically demanding since they involve either the formation of thousands of images per second, or the use of 2-D probes having a large number of elements. Therefore, great challenges must be faced for effective real-time implementation of 3 D and HFR imaging methods. My PhD activity aimed to implement and test advanced 2 D and 3 D ultrasound imaging modalities on an open research scanner called ULA OP 256. In the first part of my work, a new ultrasound imaging modality called Virtual real-time (VRT) was introduced through the modification of the firmware and software of the research scanner ULA-OP 256. With this modality, during a real-time (RT) investigation, the scanner initially acquires and stores in its memory up to 20 s of raw echo data. On user demand, the scanner can be switched to VRT mode: the stored data are re processed by the same resources used in RT but at different (typically lower) rates and, possibly, with different processing algorithms and parameters. In this way, contingent difficulties of image interpretation (especially in presence of rapidly moving phenomena), or possible computational limitations imposed by hardware during continuous RT processing can be overcome. The VRT modality has been demonstrated useful in different applications, for example, to implement a high-PRF version of the Multiline vector Doppler (MLVD) method, and a High- rame-rate CFI method, characterized by enhanced temporal and spatial resolution. The second part of my work included the software upgrade of ULA OP 256; it enabled the use of 2 D probes and the implementation of 3 D scanning methods. The ULA OP 256 can now be coupled to 2 D probes with arbitrary geometries, including matrix and sparse arrays. Furthermore, the scanner is now capable of simultaneously imaging multiple planes with programmable rotational angles. Novel approaches based on a sparse spiral array probe have been implemented and tested for different applications. For example, bi-plane imaging was evaluated for robust flow mediated dilation exams. Real-time 3 D spectral Doppler analysis was also performed. Here, two planes with programmable rotational angles were scanned to produce corresponding B-Mode images, over which multiple Doppler lines could be arbitrarily set to obtain the relative Multigate spectral Doppler (MSD) profiles. Finally, the last part of my work was specifically dedicated to the technical problems involved by HFR 3 D imaging. The management of (several) hundreds of transducer elements of a 2 D probe yields a huge amount of echo data: this makes complex and computationally expensive the processing of data volumes including thousands of lines, especially if performed at HFR. As a case report, the requirements of the main processing stages involved in ULA OP 256 receiver have been thoroughly investigated to detect and, possibly, solve the main bottlenecks. The study has evidenced that the star architecture that digitally interconnects the eight front-end boards of ULA OP 256 may frequently encounter data transfer bandwidth saturation that limits the overall performance in terms of frame/volume rate. A new architecture for data transfer has been proposed and shown effective to reduce the bandwidth requirements and thus, increase the performance of the scanner.

En la actualidad la tecnología ha avanzado considerablemente en los últimos años, volviéndose una odontología digital y considerándose ya no una herramienta del futuro, si no del presente, de modo que en la siguiente revisión de la literatura se hablará acerca del uso del escáner intraoral o por sus siglas en inglés IOS (Intra Oral Scanner) como un instrumento que nos permite a los odontólogos aplicar la tecnología en las distintas ramas como lo es la ortodoncia, operatoria dental, prótesis fija, cirugía maxilofacial, digitalizando las estructuras dentarias creando un modelo tridimensional. Se habla sobre las ventajas y desventajas del escáner comparado con el sistema convencional que todos los odontólogos conocemos que son las impresiones dentales con los distintos materiales (elastómeros, hidrocoloides). Es de gran utilidad saber lo que es el flujo digital y como lo aplicamos en el área ya que este, es una sistemática de trabajo en la que cada fase desde diagnóstico, planificación y tratamiento esta mediada por una fase digital, la cual se ha ido desarrollando, dando resultados muy confiables por lo que es una gran herramienta en la que nos podemos apoyar para brindar el mejor servicio a nuestros pacientes. Se explicarán las fases de este flujo, las cuales son digitalización, diseño y fabricación CAD CAM por sus siglas en inglés (Computer Aided Design – Computer Aided Manufacturing). CRISTINA BERNAL GONZÁLEZ 7 Un factor importante es que los precios son elevados, pero también es cierto que conforme va progresando la tecnología los precios van descendiendo, haciendo conveniente esta inversión. Por lo anterior, el objetivo de este trabajo fue analizar la literatura que se encuentra actualmente disponible sobre el tema, ya que como sabemos día con día aparecen nuevos avances digitales.

A 3D scanning system uses two cameras to extend the scanning range. The process to join two point clouds obtained from both cameras into one, which finally represents the model scanned, is called fusion. The fusion process uses the planar projection technique, thus, the fusion results are usually referred as 2.5D models. Theoretically, the fusion result of the overlapped region, which is calculated from the data sets collected by both cameras, should be closely met to each other. However, unsatisfactory fusions are derived due to the parameters of both cameras are not identical. This paper proposes a technique, which chooses three corresponding reference points from either set of scanned data to form triangles. Then, both triangles are transformed, scaled, and rotated to fit to each other and the transformation matrices are obtained. By applying the matrices to the original data sets, the revised fusion result substantially improved.

Résumé :
AbstractThis paper presents a series of attacks against Siemens S7-300 programmable logic controllers (PLCs), using our remote IHP-Attack tool. Due to the lack of integrity checks in S7-300 PLCs, such controllers execute commands whether or not they are delivered from a legitimate user. Thus, they were exposed to various kind of cyber-attacks over the last years such as reply, bypass authentication and access control attacks. In this work, we build up our tool to carry out a series of attacks based on the existing reported vulnerabilities of S7-300 PLCs in the research community. For real world experimental scenarios, our tool is implemented on real hardware/software used in industrial settings (water level control system). IHP-Attack consists of many functionalities as follows: PNIO Scanner to Scan the industrial network and detect any available PLCs/CPs, etc. Inner Scanner to collect critical data about the target PLC’s software blocks. Authentication Bypass to check whether the PLC is password protected, and compromise the PLC. Our tool also shows that once an adversary reaches the target, he is capable of carrying out severe attacks e.g. replay and control hijacking attacks against the compromised controller. All the functions used in our tool are written in Python and based on powerful libraries such as Python-Snap7 and Scapy. The attacks performed in this work generate a very small traffic overhead and a quite short attack time which make them hard to detect by the workstation. We eventually found that deploying traditional detection methods is not sufficient to secure the system. Therefore, we suggest some possible mitigation solutions to secure industrial systems based on S7-300 PLCs from such attacks.

Résumé :
Fingerprint scanners are significant devices in professional life, and its contamination can be potential sources of COVID-19 transmission. Manual disinfection of the fingerprint scanner after every single use is time consuming and even can adversely affect its electronics/functioning. Thus, with an aim to prevent the spread of infectious disease by cross contamination and implement the safe use of fingerprint scanner, we have developed a smart quick fix technology for automatic disinfection of finger print scanner glass after every single use. The smart portable top mount assembly uses two different disinfecting methods that ensures higher degree of disinfection. The disinfection is based on the simultaneous ultraviolet (UV) and heat treatment for a specific short time, and required to kill all the viruses on the scan glass surface. Moreover, developing this disinfecting technology with a universal design that can be fitted to any finger print scanner irrespective to its size makes it a novel idea.

Résumé :
3D scanning has evolved as one of the most advanced and accurate technology to measure humans and products. Quick and reliable results achieved by 3D scanning over manual measurements, make it the most preferred tool for measurement. 3D scanning has been extensively used in various national sizing surveys worldwide. The 3D scan results are compared to the manual measurements to establish the accuracy of the scanner. This research paper describes a novel and alternative approach to check the reliability and validity of the measures derived from 3D Body Scanner in comparison to measures provided by the manual measures.The 3-D Body scanning was done by Sizestream 3D Body Scanner - SS14. The manual body measurements were taken by experienced experts using an anthropometer, stadiometer, and certified flexible non-stretchable steel tape. In total 133 subjects (68 male and 65 female subjects) covering 102 body dimensions were taken manually and were used while comparing 3D scan measurements to establish the validity and reliability of the scanner. The procedure adopted for validation and reliability check for the 3D scanner was as prescribed in the ISO 20685(2005) and ISO 20685(2018). It was observed that the Sizestream - SS14 scanners used were highly consistent in measuring the subjects, though a systematic error was reported in the process failing some of the measurements in terms of accuracy levels (as per ISO 8559 and ISO 20685(2005)) achieved against manual measurements used as the gold standards. Subsequently, a novel approach based on regression modeling was applied to establish scanning accuracy.This research paper describes the validation and reliability procedure as per ISO protocols. It also discusses the regression-based statistical procedure adopted to confirm the desired measurement accuracy of the scanners within the permissible error limits of ISO 20685and ISO 8559.

Résumé :
Docker container technology is a new virtualization technique that is extremely efficient throughout the development and deployment phases. Although Docker container technology is more convenient than traditional virtualization technology (virtual machines); it suffers from weak security due to inexperienced Docker image auditing techniques. To protect the host computer or local Docker containers from malicious Docker containers, it is required to detect potential hazards in Docker images and identify risks when Docker container instances are running on the host computer. This paper proposes a tool to give the cumulative report of the three major open-source vulnerability scanners like Trivy, Clair, and Grype.

Résumé :
The purpose of this document is to provide readers with the coding protocol that authors used to code 22 meta-analyses focused on mathematics interventions for students with or at-risk of disabilities. The purpose of the systematic review was to evaluate reporting quality in meta-analyses focused on mathematics interventions for students with or at risk of disabilities. To identify meta-analyses for inclusion, we considered peer-reviewed literature published between 2000 and 2020; we searched five education-focused electronic databases, scanned the table of contents of six special education journals, reviewed the curriculum vitae of researchers who frequently publish meta-analyses in mathematics and special education, and scanned the reference lists of meta-analyses that met inclusion criteria. To be included in this systematic review, meta-analyses must have reported on the effectiveness of mathematics-focused interventions, provided a summary effect for a mathematics outcome variable, and included school-aged participants with or at risk of having a disability. We identified 22 meta-analyses for inclusion. We coded each meta-analysis for 53 quality indicators (QIs) across eight categories based on recommendations from Talbott et al. (2018). Overall, the meta-analyses met 61% of QIs and results indicated that meta-analyses most frequently met QIs related to providing a clear purpose (95%) and data analysis plan (77%), whereas meta-analyses typically met fewer QIs related to describing participants (39%) and explaining the abstract screening process (48%). We discuss the variation in QI scores within and across the quality categories and provide recommendations for future researchers so that reporting in meta-analyses may be enhanced. Limitations of the current study are that grey literature was not considered for inclusion and that only meta-analyses were included; this limits the generalizability of the results to other research syntheses (e.g., narrative reviews, systematic reviews) and publication types (e.g., dissertations).

Micro-terrain and canopy feature extraction by breakline and differencing analysis of gridded elevation models : identifying terrain model discontinuities with application to off-road mobility modeling.

Texte intégral
Résumé :
Elevation models derived from high-resolution airborne lidar scanners provide an added dimension for identification and extraction of micro-terrain features characterized by topographic discontinuities or breaklines. Gridded digital surface models created from first-return lidar pulses are often combined with lidar-derived bare-earth models to extract vegetation features by model differencing. However, vegetative canopy can also be extracted from the digital surface model alone through breakline analysis by taking advantage of the fine-scale changes in slope that are detectable in high-resolution elevation models of canopy. The identification and mapping of canopy cover and micro-terrain features in areas of sparse vegetation is demonstrated with an elevation model for a region of western Montana, using algorithms for breaklines, elevation differencing, slope, terrain ruggedness, and breakline gradient direction. These algorithms were created at the U.S. Army Engineer Research Center – Geospatial Research Laboratory (ERDC-GRL) and can be accessed through an in-house tool constructed in the ENVI/IDL environment. After breakline processing, products from these algorithms are brought into a Geographic Information System as analytical layers and applied to a mobility routing model, demonstrating the effect of breaklines as obstacles in the calculation of optimal, off-road routes. Elevation model breakline analysis can serve as significant added value to micro-terrain feature and canopy mapping, obstacle identification, and route planning.

Texte intégral
Résumé :
European societies need to increase the participation in work over the life course to support the provision of qualified labour and to meet the challenges for social security systems under the condition of their ageing populations. One of the key ambitions is to extend people’s working lives and to postpone labour market exit and retirement where possible. This requires informed policies, and the research programme EIWO – ‘Exclusion and Inequality in Late Working Life: Evidence for Policy Innovation towards Inclusive Extended Work and Sustainable Working Conditions in Sweden and Europe’ – aims to push the boundaries of knowledge about late working life and the potential of its inclusive and equal prolongation via a theoretically driven, gender-sensitive combination of multi-level perspectives. EIWO takes a life course approach on exclusion and inequality by security of tenure, quality of work, workplaces, and their consequences. It identifies life course policies, promoting lifelong learning processes and flexible adaptation to prolong working lives and to avoid increased exclusion and inequality. Moreover, it provides evidence for policies to ensure both individual, company and societal benefits from longer lives. To do so, EIWO orientates its analyses systematically to the macro-political contexts at the European Union level and to the policy goals expressed in the respective official statements, reports and plans. This report systematizes this ambitious approach. Relevant documents such as reports, green books and other publications of the European Commission (EC), the European Parliament (EP), the Organisation for Economic Co-operation and Development (OECD), as well as those of social partners and research institutions, have been systematically scanned and evaluated. In addition, relevant decisions of European summits have been considered. The selection of documents claims completeness regarding relevant and generally available publication, while relevance is defined from the point of view of EIWO’s interests. It is the aim of this report to provide a sound knowledge base for EIWO’s analyses and impact strategies and to contribute to the emerging research on the connection between population ageing and the European policies towards productivity, inclusiveness, equity, resilience and sustainability. This report aims to answer the following questions: How are EIWO’s conceptual classification and programme objectives reflected in the European Union’s policy programming? How can EIWO’s analyses and impact benefit from a reference to current EU policy considerations, and how does this focus support the outline of policy options and the formulating of possible proposals to Swedish and European stakeholders? The present report was written during early 2022; analyses were finalized in February 2022 and represent the status until this date.

Résumé :
The Coastal Observation and Analysis Branch (COAB) located at the Field Research Facility (FRF) conducts quarterly surveys and post-storm surveys along up to 60 kilometers of coastline within the vicinity of the FRF to assess, evaluate, and provide updated observations of the morphology of the foreshore and dune system. The surveys are conducted using a mobile terrestrial LiDAR scanner coupled with an Inertial Navigation System (INS). Traditionally the surveys coincide with a low tide, exposing the widest swath of visible sediment to the scanner as well as enough wind-sea swell or texture to induce wave breaking upon the interior sandbars. The wave field is measured with X-Band radar which records a spatial time series of wave direction and speed. Data for the survey region was collected using the VZ-2000's mobile, 3D scanning mode where the scanner continuously rotates the line scan 360 degrees as the vehicle progresses forward. Elevation measurements are acquired on all sides of the vehicle except for the topography directly underneath the vehicle. As the vehicle moves forward, the next rotation will capture the previous position's occluded data area. Laser data is acquired in mobile 3D radar mode with a pulse repetition rate of 300kHz, theta resolution of 0.19 degrees and phi resolution of 0.625 degrees.
