Automatic Workflow Monitoring in Industrial Environments
No full textRobust automatic workflow monitoring using visual sensors in industrial environments is still an unsolved problem. This is mainly due to the difficulties of recording data in work settings and the environmental conditions (large occlusions, similar background/foreground) which do not allow object detection/tracking algorithms to perform robustly. Hence approaches analysing trajectories are limited in such environments. However, workflow monitoring is especially needed due to quality and safety requirements. In this paper we propose a robust approach for workflow classification in industrial environments. The proposed approach consists of a robust scene descriptor and an efficient time series analysis method. Experimental results on a challenging car manufacturing dataset showed that the proposed scene descriptor is able to detect both human and machinery related motion robustly and the used time series analysis method can classify tasks in a given workflow automatically
SenseCam image localisation using hierarchical SURF trees
No full textThe SenseCam is a wearable camera that automatically takes photos of the wearer's activities, generating thousands of images per day.
Automatically organising these images for efficient search and retrieval is a challenging task, but can be simplified by providing
semantic information with each photo, such as the wearer's location during capture time. We propose a method for automatically determining the wearer's location using an annotated image database, described using SURF interest point descriptors. We show that SURF out-performs SIFT in matching SenseCam images and that matching can be done efficiently using hierarchical trees of SURF descriptors. Additionally, by re-ranking the top images using bi-directional SURF matches, location matching performance is improved further

Salient Regions for Query by Image Content
No full textMuch previous work on image retrieval has used global features such as colour and texture to describe the content of the image. However, these global features are insufficient to accurately describe the image content when different parts of the image have different characteristics. This paper discusses how this problem can be circumvented by using salient interest points and compares and contrasts an extension to previous work in which the concept of scale is incorporated into the selection of salient regions to select the areas of the image that are most interesting and generate local descriptors to describe the image characteristics in that region. The paper describes and contrasts two such salient region descriptors and compares them through their repeatability rate under a range of common image transforms. Finally, the paper goes on to investigate the performance of one of the salient region detectors in an image retrieval situation

Nota betreffende verslag inzake onderzoek verbetering afwatering Westelijk Noord-Brabant (1936)
No full textDe Hoofdingenieur-Directeur van den Rijkswaterstaat te 's-Hertogenbosch verzoekt in zijn schrijven van 14 Mei 1937 o.a. te willen nagaan of een afwatering naar de Ooster- of Westerschelde, alwaar de laagwaterstanden lager zijn dan elders, voordelen zou bieden boven een afwatering naar het Hollandsch Diep, zoals door den Provincialen Waterstaat van Noord-Brabant wordt voorgesteld. Geconcludeerd wordt dat er geen redenen gevonden zijn die twijfel aan de beginselen van het door de Provincie opgemaakte rapport zouden kunnen rechtvaardigen. Ook voor het geval niet alle gronden daarbij afdoende baat mochten vinden, zal er toch naar zijn te streven zoveel mogelijk water nabij Moerdijk (of Zwaluwe) te lozen. Te overwegen ware daarbij de mogelijkheid het afwateringskanaal dieper te maken dan op bijlage 34 wordt voorgesteld. Hierdoor zou de hoogste stand te Roville nog wel enige cm zijn te verlagen. Blijkens de hier gegeven beschouwingen, die niet op scheepvaartbelangen, doch slechts op ontwateringsbelangen betrekking hebben, zijn de voordelen eener lage laagwaterstand te Bath en Bergen op Zoom inderdaad aanwezig, doch de afstanden van de aan betere afwatering behoefte hebbende gronden tot deze punten schijnen te groot te zijn om op economische wijze partij van deze lage standen te kunnen trekken. Een lozing bij Bergen op Zoom heeft bovendien nog het bezwaar eener benadeling der oesterteelt. Aanduidingen voor bijzondere veranderingen van noemenswaardige grootte in het getijregime te Moerdijk of daaromtrent zijn blijkbaar niet aanwezig, doch met de ontworpen plaatselijke wijziging van den zuideroever van het Hollandsch Diep zal rekening zijn te houden bij het ontwerpen van den mond der verbeterde Roode Vaart. Bijgevoegd bij dit document is een nota over dit onderwerp geschreven door Prof. L. van Vuuren (gepubliceerd op 4 juli 1937
Visual saliency from image features with application to compression
No full textImage feature point algorithms and their associated regional de-scriptors can be viewed as primitive detectors of visually-salient information.In this paper, a new method for constructing a visual attention probabilitymap using features is proposed. (Throughout this work we use SURF featuresyet the algorithm is not limited to SURF alone.) This technique is validatedusing comprehensive human eye-tracking experiments. We call this algorithm\Visual Interest" (VI) since the resultant segmentation reveals image regionsthat are visually salient during the performance of multiple observer searchtasks. We demonstrate that it works on generic, eye-level photographs andis not dependent on heuristic tuning. We further show that the descriptor-matching property of the SURF feature points can be exploited via objectrecognition to modulate the context of the attention probability map for agiven object search task, rening the salient area. We fully validate the VisualInterest algorithm through applying it to salient compression using a pre-blurof non salient regions prior to JPEG and conducting comprehensive observerperformance tests. When using the object contextualisation, we conclude thatJPEG les are around 33% larger than they need to be to fully represent thetask-relevant information within them. We nally demonstrate the utility ofthe segmentation as a Region of Interest in JPEG2000 compression to achievesuperior image quality (measured statistically using PSNR and SSIM) overthe automatically-selected salient image regions while reducing the image le-size by down to 25% of that of the original. Our technique therefore deliverssuperior compression performance through the detection and selective preser-vation of visually-salient information relevant to multiple observer tasks
Human iPSC-derived motoneurons harbouring TARDBP or C9ORF72 ALS mutations are dysfunctional despite maintaining viability
No full textThis work has been supported by: Motor Neurone Disease Association (G.B.M., S.C. and C.E.S.); Euan MacDonald Centre (G.B.M. and S.C.); European Research Council (L.V.); Cambridge Hospitals National Institute for Health Research Biomedical Research Center (L.V.).Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease for which a greater understanding of early disease mechanisms is needed to reveal novel therapeutic targets. We report the use of human induced pluripotent stem cell (iPSC)-derived motoneurons (MNs) to study the pathophysiology of ALS. We demonstrate that MNs derived from iPSCs obtained from healthy individuals or patients harbouring TARDBP or C9ORF72 ALS-causing mutations are able to develop appropriate physiological properties. However, patient iPSC-derived MNs, independent of genotype, display an initial hyperexcitability followed by progressive loss of action potential output and synaptic activity. This loss of functional output reflects a progressive decrease in voltage-activated Na+ and K+ currents, which occurs in the absence of overt changes in cell viability. These data implicate early dysfunction or loss of ion channels as a convergent point that may contribute to the initiation of downstream degenerative pathways that ultimately lead to MN loss in ALS.Peer reviewe

South Ural State University, Chelyabinsk, Russian FederationВсеобщая цифровизация всех сфер деятельности человека стала важнейшим фактором влияния на коммуникативную среду общества и, как следствие, – на требования к
компетенциям выпускников вузов. Специалист по информационной безопасности (ИБ),
несмотря на сложившийся стереотип принадлежности к техническим специалистам, должен развивать умения коммуникации. Это связано с тем, что сегодня он функционально
призван оценивать человеческие риски и повышать осведомленность сотрудников организации в области информационной безопасности (ИБ-осведомленности), повышать
культуру их информационной безопасности, вовлекать их в процесс обеспечения ИБ.
Виртуализация коммуникаций обусловливает постепенную эмоциональную автономизацию субъектов, что негативно отражается на результатах деятельности специалиста по
ИБ. Автор выявил сущностные особенности и педагогические условия развития эмоциональной компетентности будущего специалиста по ИБ в условиях вуза, уточнил понятие
эмоциональной компетентности будущего специалиста по защите информации. Научная
новизна работы состоит в выявлении особенностей и условий развития эмоциональной
компетентности специалистов по защите информации в условиях вуза. Результативность
реализации этих условий в ходе обучения студентов вуза управлению информационной
безопасностью подчеркивает практическую значимость исследования. Comprehensive digitalization of all spheres of human activity has become the most important
factor influencing the communicative environment of society and resulted in new requirements
to the competencies of university graduates. An information security specialist (IS) is
a technical specialist that has to develop soft skills. It can be explained by the fact that he has to
assess human risks; to raise information security awareness of the organization's employees;
to increase information security culture; and to involve company’s employees in the information
security process. The virtualization of communications determines the gradual emotional autonomy
of subjects, which negatively affects the results of the activity of an information security
specialist. Thus, the author defines the essential features and pedagogical conditions for the development
of emotional competence of a future information security specialist in a university
environment. The author clarified the concept of emotional competence of a future information
security specialist. The scientific novelty is in identifying the features and conditions for the development
of the emotional competence of information security specialists in a university environment.
The effectiveness of the implementation of these conditions during the training of
university students in information security management emphasizes the practical significance
of the study
