Resumen
An application of a robotic system integrated with a vision system is presented. The robot is a 3-axis revolute prototype, while the vision system essentially consists in a laser scanner made up of a camera and a linear laser projector. Both the robotic and the video system were designed and built at DIME (Department of Mechanical Engineering for Energetics), University of Naples Federico II. The presented application essentially consists of a laser scanner that is installed on the robot arm; the scanner scans a 3D surface, and the data are converted in a cloud of points in the robot’s workspace. Then, starting from those points, the end-effector trajectories adopted to replicate the scanned surface are calculated; so, the same robot, by using a tool, can reproduce the scanned object. The software was developed also at the DIME. The adopted tool was a high-speed drill, installed on the last link of the robot arm, with a spherical milling cutter in order to obtain enough accurate surfaces by the data represented by the cloud of points. An algorithm to interpolate the paths and to plan the trajectories was also developed and successfully tested.

Resumen
Capturing the fine details on the surface of small objects is a real challenge to many conventional surveying methods. Our paper discusses the investigation of several data acquisition technologies, such as arm scanner, structured light scanner, terrestrial laser scanner, object line-scanner, DSLR camera, and mobile phone camera. A palm-sized embossed sculpture reproduction was used as a test object; it has been surveyed by all the instruments. The result point clouds and meshes were then analyzed, using the arm scanner’s dataset as reference. In addition to general statistics, the results have been evaluated based both on 3D deviation maps and 2D deviation graphs; the latter allows even more accurate analysis of the characteristics of the different data acquisition approaches. Additionally, own-developed local minimum maps were created that nicely visualize the potential level of detail provided by the applied technologies. Besides the usual geometric assessment, the paper discusses the different resource needs (cost, time, expertise) of the discussed techniques. Our results proved that even amateur sensors operated by amateur users can provide high quality datasets that enable engineering analysis. Based on the results, the paper contains an outlook to potential future investigations in this field.

Resumen
Our aim was to examine the impact of different arm positions during imaging of the localizer radiograph(s) on effective dose for exposure-controlled computed tomography (CT) (Siemens/Canon) scans of the neck to pelvis. An anthropomorphic whole-body phantom was scanned from the neck to pelvis with the arms positioned in three different ways during the acquisition of the localizer radiograph: (i) above the head, (ii) alongside the trunk, and (iii) along the trunk with the hands placed on the abdomen. In accordance with clinical routines, the arms were not included in the subsequent helical scans. Effective doses were computed to a standard-sized patient (male/female) using a dedicated system-specific Monte Carlo-based software. Effective doses for the Canon CT scanner for the different alternatives (male/female) were (a) 5.3/6.62 mSv, (b) 5.62/7.15 mSv and (c) 5.92/7.44 mSv. For the Siemens CT scanner, effective doses were (a) 4.47/5.59 mSv, (b) 5.4/6.69 mSv and (c) 5.7/6.99 mSv. Arms placed above the head during localizer radiograph imaging in the current CT procedures substantially reduced the total effective dose to the patient.

Resumen
The paper subscribes development of Magnetic Resonance Imaging (MRI) compatible using an ultrasonic motor, to work within the limits of MRI scanner workspace and environment, dimensions involving upper-limbs biomechanics. The manipulandum consists of hand mechanism and an arm-reaching mechanism having a two-degree-freedom (2DOF) haptic interface enabling human subject to conduct reaching movement comfortably within MRI workspace. The kinematics structure of the manipulandum is optimized for MRI space and movement. We have confirmed the manipulandum's MRI compatibility in experiments.

Resumen
Background Geometric morphometrics is a powerful approach to capture and quantify morphological shape variation. Both 3D digitizer arms and structured light surface scanners are portable, easy to use, and relatively cheap, which makes these two capturing devices obvious choices for geometric morphometrics. While digitizer arms have been the “gold standard”, benefits of having full 3D models are manifold. We assessed the measurement error and investigate bias associated with the use of an open-source, high-resolution structured light scanner called SeeMaLab against the popular Microscribe 3D digitizer arm. Methodology The analyses were based on 22 grey seal (Halichoerus grypus) skulls. 31 fixed anatomical landmarks were annotated both directly using a Microscribe 3D digitizer and on reconstructed 3D digital models created from structured light surface scans. Each skull was scanned twice. Two operators annotated the landmarks, each twice on all the skulls and 3D models, allowing for the investigation of multiple sources of measurement error. We performed multiple Procrustes ANOVAs to compare the two devices in terms of within- and between-operator error, to quantify the measurement error induced by device, to compare between-device error with other sources of variation, and to assess the level of scanning-related error. We investigated the presence of general shape bias due to device and operator. Results Similar precision was obtained with both devices. If landmarks that were identified as less clearly defined and thus harder to place were omitted, the scanner pipeline would achieve higher precision than the digitizer. Between-operator error was biased and seemed to be smaller when using the scanner pipeline. There were systematic differences between devices, which was mainly driven by landmarks less clearly defined. The factors device, operator and landmark replica were all statistically significant and of similar size, but were minor sources of total shape variation, compared to the biological variation among grey seal skulls. The scanning-related error was small compared to all other error sources. Conclusions As the scanner showed precision similar to the digitizer, a scanner should be used if the advantages of obtaining detailed 3D models of a specimen are desired. To obtain high precision, a pre-study should be conducted to identify difficult landmarks. Due to the observed bias, data from different devices and/or operators should not be combined when the expected biological variation is small, without testing the landmarks for repeatability across platforms and operators. For any study necessitating the combination of landmark measurements from different operators, the scanner pipeline will be better suited. The small scanning-related error indicates that by following the same scanning protocol, different operators can be involved in the scanning process without introducing significant error.

Resumen
Recently published approaches to SLAM algorithms process laser sensor measurements and output a map as a point cloud of the environment. Often the actual precision of the map remains unclear, since SLAMalgorithms apply local improvements to the resulting map. Unfortunately, it is not trivial to compare the performance of SLAMalgorithms objectively, especially without an accurate ground truth. This paper presents a novel benchmarking technique that allows to compare a precise map generated with an accurate ground truth trajectory to a map with a manipulated trajectory which was distorted by different forms of noise. The accurate ground truth is acquired by mounting a laser scanner on an industrial robotic arm. The robotic arm is moved on a predefined path while the position and orientation of the end-effector tool are monitored. During this process the 2D profile measurements of the laser scanner are recorded in six degrees of freedom and afterwards used to generate a precise point cloud of the test environment. For benchmarking, an offline continuous-time SLAM algorithm is subsequently applied to remove the inserted distortions. Finally, it is shown that the manipulated point cloud is reversible to its previous state and is slightly improved compared to the original version, since small errors that came into account by imprecise assumptions, sensor noise and calibration errors are removed as well.

Resumen
The aim of this study was to evaluate the accuracy of two intraoral scanners used in the dental office. A molar fixed in a typodont was prepared for a ceramic onlay. The preparation was scanned using a high-resolution scanner (reference scanner) and saved as stereolithography (STL) format. The prepared resin molar was scanned again using the intraoral scanners, and all the scans were saved as well in STL format. All STL files were compared using metrology software (Geomagic Control X). Overlapping the meshes allowed the assessment of the scans in terms of trueness and precision. Based on the results of this study, the differences of trueness and precision between the intraoral scanners were minimal.

Resumen
La microarchitecture osseuse est un des déterminants de la qualité osseuse qui peut maintenant être évalué in vivo au radius et au tibia distal avec une résolution isotropique de 82μm par un nouveau scanner à haute résolution (XtremeCT, SCANCO Medical AG). Nous avons montré qu’il s’agissait d’une technique prometteuse pour évaluer la densité et la microarchitecture osseuse au niveau de sites périphériques, tant par sa reproductibilité (CV variant de 0,7 à 4,4%) que sa capacité à détecter des changements liés à l’âge ou à la maladie (ostéopénie ou ostéoporose). Nous avons également montré que cette microarchitecture était associée aux fractures de fragilité indépendamment, pour partie, de la densité osseuse mesurée par DXA. En couplant ces mesures à une analyse par éléments finis, nous avons pu estimer que les propriétés mécaniques de l’os pourraient fournir des informations sur la fragilité osseuse et le risque de fracture non évaluées par sa densité ou sa microarchitecture seule
Bone microarchitecture is one of the determinants of bone quality that can now be evaluated in vivo at the distal radius and tibia with an isotropic resolution of 82μm with a new high-resolution peripheral scanner (XtremeCT, SCANCO Medical AG). Our studies show that this technique is promising to assess bone density and microarchitecture at peripheral skeletal sites, both in terms of reproducibility (CV ranging from 0. 7 to 4. 4%) and ability to detect age and disease-related changes (osteopenia or osteoporosis). We also demonstrated that this microarchitecture is associated with fragility fractures partly independent of bone density as assessed by DXA. When finite element analysis was added to this technique, we determined that bone mechanical properties can provide information about skeletal fragility and fracture risk not assessed by density or microarchitecture measurements alone

Neste trabalho foram determinadas as condições para a soldagem de chapas grossas de aço carbono ASTM A36 com aço baixo-liga temperado e revenido ASTM A514 Grau Q empregando-se o processo arame tubular. Para tanto foram soldadas diversas peças de testes com o intuito de se avaliar as condições mais adequadas de preparação e soldagem de juntas dissimilares destes materiais. A preparação foi realizada por meio de corte térmico. A temperatura de preaquecimento foi determinada através de modelos matemáticos, pelas recomendações das normas AWS D1.1 e DIN EN 1011-2 sendo posteriormente avaliada por intermédio do teste de soldabilidade tipo CTS Controlled Thermal Severity. Os parâmetros de soldagem foram determinados a partir da qualificação de um procedimento de soldagem, conforme a norma AWS D1.1. Foram avaliadas as consequências do emprego do tratamento térmico de alívio de tensões após soldagem (TTAT), pelos testes de dureza Vickers e impacto Charpy. A caracterização microestrutural foi realizada por meio de microscopia óptica e microscopia eletrônica de varredura. A caracterização das superfícies oxicortadas evidenciou os efeitos da descarbonetação e também da carbonetação. A temperatura de pré-aquecimento de 160°C determinada por meio da metodologia recomendada pelas normas AWS D1.1 e DIN EN 1011-2 mostrou-se satisfatória nos testes de soldabilidade. Foi possível a qualificação do procedimento de soldagem (EPS) com requisitos de impacto na condição \"como soldado\", porém na condição \"após TTAT\", os baixos valores de tenacidade obtidos no metal de solda, inferiores a 27J, não permitiram a qualificação de uma EPS com requisitos de impacto. Foi observada a ausência de trincas intergranulares tanto na zona afetada pelo calor quanto no metal de base ASTM A514, porém foi revelada a presença de microfases frágeis no metal de solda na condição \"como soldado\", especificamente na região da raiz, intensificadas pelo efeito da diluição. O aumento do teor de carbono na raiz, a presença de microfases frágeis, a grande fração de grãos colunares e de ferrita proeutetóide combinados com a baixa fração de ferrita acicular no metal de solda contribuíram para os baixos valores de tenacidade encontrados na condição \"como soldado\". Após o TTAT observou-se uma queda acentuada da tenacidade, inferior a 27J, do metal de solda devido à fragilização provocada pela precipitação e coalescimento de carbonetos de ferro.

Resumen
Afin de répondre à des besoins croissants en nano-caractérisation, nous avons développé une plateforme multifonctionnelle combinant des techniques de microscopie optique et de microscopies en champ proche.Au coeur de ce dispositif se trouve l'échantillon. Ceux optiquement semi-transparents en exploiteront au mieux la palette des techniques implémentées. Parmi eux des couches minces (100nm), nanostructurées, de matériaux organiques photovoltaïques.La plateforme permet d'utiliser différentes techniques de microscopies à sonde locale (AFM1, KPFM2, SNOM3, ...) couplées à un microscope optique inversé qui autorise illumination ou imagerie. Versatile, elle peut accueillir des portes-échantillons d'autres techniques développées ou présentes au laboratoire (en particulier les microscopies électroniques à projection, à transmission ou à balayage). Elle est également conçue pour faciliter l'intégration d'autres techniques.Outre le développement de la plateforme, ce manuscrit montre la part importante du travail effectuée pour mettre au point et exploiter une microscopie à sonde de Kelvin (KPFM) à haute résolution sous illumination.Des résultats obtenus sur des matériaux organiques photovoltaïques permettent notamment d'illustrer les excellentes performances de notre plateforme de nano-caractérisation et des techniques associées
To address the increasing demand on nanomaterials investigation, we developed a cross-characterization platform combining scanning probe microscopies (AFM 1, KPFM 2, SNOM 3, ...) and inverted optical microscopy. The inverted optical microscope, allowing both illumination and imaging, is augmented with near field microscopies such as cited above.The heart of our setup is the sample. Optically semi-transparent samples will best benefit the range of implemented complementary technics, among these samples, nanostructured organic photovoltaic thin (100nm) films. However, the flexible platform is thought to be adaptable to other samples and thus sample-holders used for other characterization techniques existing in the Institute, such as scanning or transmission electron or projection microscopies. The platform is also designed to simplify future extension to other experimental technics.Beyond the platform itself, the manuscript shows the important effort devoted to develop, and take benefit of, a Kelvin probe microscopy under illumination.Results obtained on organic photovoltaic materials demonstrate the possibilities of our original setup and prove its performance to be at state of the art

The study integrates structure light system with six-axis manipulator to examine the algorithm performance in different situation. Generally, based on the CAD model, flat patch recursive algorithm is used to calculate the scanning gestures for robot equipped with a 3D scanner. However, the required number of gestures calculated by flat patch recursive algorithm is significant for CAD model with huge number of meshes. To improve the efficiency of existing scanning gesture searching algorithm, this study expanded the concept of region growing which is commonly used in image segmentation to three-dimensional mesh model to calculate the potential scanning gestures. In this study, seven different objects with CAD models have been used to compare performance between the proposed algorithm and flat patch recursive algorithm. The experimental result shows that although the scanning area is a little bit less than the existing algorithm, the number of scanning gesture of proposed algorithm is significantly reduced and thus prevents accumulating error resulted from multiple view registration. In addition, the computation time of proposed algorithm is less than the one of flat patch recursive algorithm.

The great majority of patients with upper extremity lymphedema are the women with breast cancer. Breast cancer related lymphedema typically affects the ipsilateral upper extremity. Breast cancer surgery is also the most common cause of secondary lymphedema in the upper extremity. Early-stage diagnosis and proper treatment are necessary for these patients; otherwise, it may cause irreversible damage. Such early-stage lymphedema is considered reversible with treatment because the skin and tissues haven't been permanently damaged. Although a clinical measure device of lymphedema is already seen. A reliable, valid, real-time monitoring and easy-operating measurement of lymphedema is still expected. In this study, we hope to develop a lightweight device with above features that patients with upper extremity lymphedema can use and can monitor the volume of the lymphedema on their own whenever they want to. These digitalized data can provide a better follow-up for medical use. The study can be divided into two part. First, we choose 3D scanner as a tool and calculate the scanned model volume. “iSense” is the scanner selected in consideration of the light-weight feature. While the devices can operate more efficiently on triangles that are groups into meshes, this is how we calculated a tetrahedral volume mesh. Each tetrahedron has 4 triangular faces, we sum the tetrahedrons to get the volume; and for the repeating issue, we solve it with “signed.” In the second part of the study, we replaced the 3D scanner with a mobile phone camera. We use the camera to capture images of the models, then developed a volume predicting method from calculating the image pixels. We used the python program platform supported with open source “Opencv.” It provides many commonly used functions for image recognition. After taking the pictures, we converted them into grayscale images. And, the filter function allows us to filter a range of data based on the criteria we had defined while the edge calculation helps us to find the target's location. Based on all calculus algorithm, the volume of the target is available.

Resumen
The geometric method rests heavily on the assumption that the aim of a moral analysis of technology is to determine what professional engineers, designers, and ordinary users ought to do when confronted with ethical issues triggered by new or existing technologies. Some scholars reject this assumption. According to an influential tradition, the central research question for a moral analysis of technology should be to establish what ethical values, norms, or other moral properties are embedded in technological artifacts qua artifacts. On this view guns, cars, and obstetric ultrasound scanners are no mere tools; they have moral properties of their own. This chapter discusses this artifact approach to the ethics of technology.

Resumen
Modern digital echo laboratories are based on echo scanners working in a network with file server(s) and work-station computers for offline analysis and reporting. They may be based on vendor-specific software, but are preferably based on vendor-independent software solutions, being able to handle data from all brands of scanners. To enable analysis of advanced echocardiographic techniques, plug-ins for vendor-specific solutions should be integrated in the otherwise vendor-independent software. To obtain full efficiency, the system should be integrated with the hospital information system for patient demographics and scheduling, and the approved report should automatically be returned to the electronic patient record without the need for scanning or other handling by manpower. To obtain this, a variety of standards have been developed, most of them for medical imaging in general. Scanners of all major brands deliver data compatible with those standards, even if compatibility problems may occur. When the optimal solution for the individual organization has been established, running the echo lab changes significantly. Digital images are stored on safe repositories without quality loss and are available for viewing outside the echo lab. Offline measurements, structured reporting, education, research, quality control, and financial analyses are available. The lab becomes more efficient and cost-effective.

Resumen
According to the inner-sense theory, one finds out about one’s own mind by deploying a (quasi-)perceptual mechanism, or “internal scanner.” The theory defended in TS&K is not a version of the inner-sense theory, but there are commonalities. This chapter examines eight leading objections to the inner-sense theory, and argues that they leave it pretty much unscathed. However, as explained at the end, there are some residual puzzles. Although the inner-sense theory offers a nice explanation of peculiar access, it offers none at all of privileged access. Further, it gives no explanation of why Shoemakerian “self-blindness” does not actually occur. This motivates an examination of some leading alternatives.

Positron emission tomography (PET) is an imaging method that utilizes compounds labeled with positron-emitting radioisotopes as molecular probes to evaluate different neurophysiological processes quantitatively and noninvasively. This chapter provides a background regarding positron emission, radiotracer chemistry, and detector and scanner instrumentation, as well as analytical methods for evaluating basic brain physiology, such as cerebral blood flow and oxygen and glucose metabolism. The methodological aspects of PET imaging, such as patient preparation and optimal scanning parameters, are discussed. Examples of application of blood flow and metabolic imaging in both research and clinical scenarios for the evaluation of normal neurophysiology are provided. Recent advances in PET imaging, including PET-CT and PET-MRI, are also described. Finally, the unique strengths of PET imaging are highlighted.

Resumen
Abstract3D personal data is a type of data that contains useful information for product design, online sale services, medical research and patient follow-up.Currently, hospitals store and grow massive collections of 3D data that are not accessible by researchers, professionals or companies. About 2.7 petabytes a year are stored in the EU26.In parallel to the advances made in the healthcare sector, a new, low-cost 3D body-surface scanning technology has been developed for the goods consumer sector, namely, apparel, animation and art. It is estimated that currently one person is scanned every 15 min in the USA and Europe. And increasing.The 3D data of the healthcare sector can be used by designers and manufacturers of the consumer goods sector. At the same time, although 3D body-surface scanners have been developed primarily for the garment industry, 3D scanners’ low cost, non-invasive character and ease of use make them appealing for widespread clinical applications and large-scale epidemiological surveys.However, companies and professionals of the consumer goods sector cannot easily access the 3D data of the healthcare sector. And vice versa. Even exchanging information between data owners in the same sector is a big problem today. It is necessary to overcome problems related to data privacy and the processing of huge 3D datasets.To break these silos and foster the exchange of data between the two sectors, the BodyPass project has developed: (1) processes to harmonize 3D databases; (2) tools able to aggregate 3D data from different huge datasets; (3) tools for exchanging data and to assure anonymization and data protection (based on blockchain technology and distributed query engines); (4) services and visualization tools adapted to the necessities of the healthcare sector and the garment sector.These developments have been applied in practical cases by hospitals and companies of in the garment sector.

Resumen
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.

Resumen
AbstractTor exit relays are operated by volunteers and the trustworthiness of Tor exit relays need to be revisited in a long-term manner. In this paper, we monitored the Tor network by developing a fast and distributed exit relay scanner (ExitSniffer) to probe all exit relays over a period of 16 months continuously, seeking to expose the anomalous binding relationship phenomena of exit routers simply by comparing the returnIP and consensusIP. We totally find 1983 malicious exit relays which average contribute 10.12% bandwidth of total Tor exit relays bandwidth monthly, resulting tremendous threaten for Tor user’s anonymity according to the current path-relay selecting algorithm. There exits two types of anomalous binding relationship consists 35 exit relay families, with different size ranging from 2 to 230, which are neither announced in the consensus document or detected by the Tor network.

Resumen
For many scanning applications, the scan line straightness, linearity, and influence of mechanical wobble and eccentricity on a scanner's performance are important. Some different 2-D scanners are compared on a common specification of a total resolution of 6.25 million pixels. According to our analyses, the polygon-mirror system offers the best straightness but is the most sensitive to mechanical wobble and eccentricity.1 Different holographic 2-D scanners are also investigated, and their performances depends strongly on design parameters and on the configurations. The scan line straightness of the grating scanner’s system is comparable with that of a polygon mirror.2 The scan line linearity of the scanner with an auxiliary reflector3 is the best one. The simplicity and therefore the expected reliability of holographic scanners may influence people to prefer holographic scanners. However many technical problems remain to be solved before holographic scanners can be widely used.

Resumen
This work presents a feasibility study in estimating the displacement of a moving tendon using Pulsed-Wave Doppler ultrasound. The displacement estimation is accomplished using a tendon mimicking experiment, by performing a Fourier analysis of audio-based output signals from a commercial ultrasound scanner. The feasibility study shows that our proposed technique is better able to measure the actual tendon displacement, in comparison to the scanner’s onboard software, for the purposes of determining near-surface tissue excursion (i.e. displacement). The proposed technique also demonstrates that data acquisition from the audio output signal of a portable ultrasound scanner is possible, and can be processed with custom software to achieve our purpose. The motivation for this work is to noninvasively and dynamically monitor the displacement of the major tendons in the human lower arm. Such tendon displacement monitoring can provide an important diagnostic tool for people with hand injuries.

Texto completo
Resumen
Piezoelectric tube scanners are commonly used in Scanning Probe Microscopy (SPM) to provide the scanning motion of the tip or sample. Oscillations due to the weakly damped resonances of the scanner are a major source of image distortion in SPM-imaging. In this contribution, multiple input-multiple output (MIMO) self-sensing actuation of a piezoelectric tube scanner is presented, allowing to actively dampen the scanner oscillations. By connecting the tube scanner in a capacitive bridge-circuit, the piezoelectric tube is simultaneously used as a sensor and actuator. In order to enable the use of low-order decentralized controllers, the cross-talk between both axes is reduced by compensating for the capacitive coupling. The MIMO self-sensing actuation allows to actively dampen the scanner’s fundamental resonance by 18dB, while simultaneously reducing the resonance induced coupling by 30dB. Experimental results verify a significant reduction of the scanner oscillations in both positioning axes during fast scanning.

Resumen
The recent advancement of 3D non-contact laser scanners enables fast measurement of parts by generating huge amount of coordinate data for a large surface area in a short time. In contrast, traditional tactile probes in the coordinate measurement machines (CMM) can generate more accurate coordinate data points in a much slower pace. Therefore the combination of laser scanners and touch probes can potentially lead to more accurate, faster and denser measurement. In this paper, we develop a dynamic sensing-and-modeling approach for integrating a tactile point sensor and an area laser scanner to improve the measurement speed and quality. The part is first laser scanned to capture the overall shape of the object. It is then probed via a tactile sensor at positions are dynamically determined to reduce the measurement uncertainty based on a novel next-best-point formulation. Technically, we use the Kalman filter to fuse laser scanned point cloud and tactile points and to incrementally update the surface model based on the dynamically probed points. We solve the next-best-point problem by transforming the B-spline surface’s uncertainty distribution into a higher dimensional uncertainty surface so that the convex hull property of the B-spline surface can be utilized to dramatically reduce the search speed and to guarantee the optimality of the resulting point. Three examples in this paper demonstrate that the dynamic sensing-and-modeling effectively integrates the area laser scanner and the point touch probe and leads to significant amount of measurement time saving (at least several times in all three cases). This dynamic approach’s further benefits include reduced surface uncertainty due to the maximum uncertainty control through the next-best-point sensing and improved surface accuracy in surface reconstruction through the use of Kalman filter to account various sensor noise.

We analyzed the main cloud services in the article. We also described the main contribution of mobile cloud technology to education. The article presents the author’s development from the field of mobile cloud education in higher mathematics. The design architecture of this application is described in detail: QR generator and scanner, authorization, sending tasks. Block diagrams and images are presented that clearly demonstrate the operation of the application. We showed an example of solving the integral from the section of integral calculus for higher mathematics and showed how to download the answer in the form of a QR code and find out whether it is correct or incorrect (this can be seen by the color on the smart phone screen). It is shown how this technology helps the teacher save time for checking assignments completed by students. This confirms its effectiveness.

Resumen
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. Engineer Research and Development Center (U.S.), abril de 2021. http://dx.doi.org/10.21079/11681/40185.

Texto completo
Resumen
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.

Texto completo
Resumen
Recent advances in visual sensing technology have gained much attention in the field of bridge inspection and management. Coupled with advanced robotic systems, state-of-the-art visual sensors can be used to obtain accurate documentation of bridges without the need for any special equipment or traffic closure. The captured visual sensor data can be post-processed to gather meaningful information for the bridge structures and hence to support bridge inspection and management. However, state-of-the-practice data postprocessing approaches require substantial manual operations, which can be time-consuming and expensive. The main objective of this study is to develop methods and algorithms to automate the post-processing of the visual sensor data towards the extraction of three main categories of information: 1) object information such as object identity, shapes, and spatial relationships - a novel heuristic-based method is proposed to automate the detection and recognition of main structural elements of steel girder bridges in both terrestrial and unmanned aerial vehicle (UAV)-based laser scanning data. Domain knowledge on the geometric and topological constraints of the structural elements is modeled and utilized as heuristics to guide the search as well as to reject erroneous detection results. 2) structural damage information, such as damage locations and quantities - to support the assessment of damage associated with small deformations, an advanced crack assessment method is proposed to enable automated detection and quantification of concrete cracks in critical structural elements based on UAV-based visual sensor data. In terms of damage associated with large deformations, based on the surface normal-based method proposed in Guldur et al. (2014), a new algorithm is developed to enhance the robustness of damage assessment for structural elements with curved surfaces. 3) three-dimensional volumetric models - the object information extracted from the laser scanning data is exploited to create a complete geometric representation for each structural element. In addition, mesh generation algorithms are developed to automatically convert the geometric representations into conformal all-hexahedron finite element meshes, which can be finally assembled to create a finite element model of the entire bridge. To validate the effectiveness of the developed methods and algorithms, several field data collections have been conducted to collect both the visual sensor data and the physical measurements from experimental specimens and in-service bridges. The data were collected using both terrestrial laser scanners combined with images, and laser scanners and cameras mounted to unmanned aerial vehicles.

Texto completo
Resumen
This paper presents an exploratory study of GPS data from a private-sector data provider for analysis of trip generation, route choice, and trip chaining. The study focuses on travel to and from the Indianapolis International Airport. GPS data consisting of nearly 1 billion waypoints for 12 million trips collected over a 6-week period in the state of Indiana. Within this data, there were approximately 10,000 trip records indicating travel to facilities associated with the Indianapolis airport. The analysis is based the matching of waypoints to geographic areas that define the extents of roadways and various destinations. A regional analysis of trip ends finds that travel demand for passenger services at the airport extends across a region spanning about 950 km. Local travel between land uses near the airport is examined by generation of an origin-destination matrix, and route choice between the airport and downtown Indianapolis is studied. Finally, the individual trips are scanned to identify trip chaining behavior. Several observations are made regarding these dynamics from the data. There is some sample bias (types of vehicles) and opportunities to further refine some of the land use definitions, but the study results suggest this type of data will provide a new frontier for characterizing travel demand patterns at a variety of scales.

Resumen
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.

Resumen
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. Horizontal Datum NAD83(2011), Projection North Carolina State Plane (3200) meters; Vertical Datum NAVD88, meters with geoid09 applied.
