Skin cancer is the most frequent malignant neoplasm for Caucasian individuals. According to the Skin Cancer Foundation, the incidence of melanoma, the most malignant of skin tumours, and resultant mortality, have increased exponentially during the past 30 years, and continues to grow. [1]. Although often intractable in advanced stages, skin cancer in general and melanoma in particular, if detected in an early stage, can achieve cure ratios of over 95% [1,55]. Early screening of the lesions is, therefore, crucial, if a cure is to be achieved. Most skin lesions classification systems rely on a h

Streszczenie:

Malignant melanoma (MM) is a type of skin cancer that is associated with a very poor prognosis and can often lead to death. Early detection is crucial in order to administer the right treatment successfully but currently requires the expertise of a dermatologist. In the past years, studies have shown that automatic detection of MM is possible through computer vision and machine learning methods. Skin lesion segmentation and classification are the key methods in supporting automatic detection of different skin lesions. Compared with traditional computer vision as well as other machine learning

When forensic examiners try to identify the perpetrator of a felony, they use individual facial marks when comparing the suspect with the perpetrator. Facial marks are often used for identification and they are nowadays found manually. To speed up this process, it is desired to detect interesting facial marks automatically. This master thesis describes a method to automatically detect and separate permanent and non-permanent marks. It uses a fast radial symmetry algorithm as a core element in the mark detector. After candidate skin mark extraction, the false detections are removed depending on

Today, computer aided diagnosis (CADx) is a common occurrence in hospitals. With image recognition, computers are able to detect signs of breast cancer and different kinds of lung diseases. For a convolutional neural network (CNN) that classifies images, the accuracy depends on the amount of data it is trained on and performs better as the amount of training data increase. This introduces a need for relevant images for the classes the classifier is supposed to differentiate between. However, when input data is increased, so does the computational cost, leading to a trade-off between accuracy a

Streszczenie:

Recent studies report about the need for and difficulties in measuring technical working skills among vocational high school students worldwide (Mabed & Köhler, 2018). Often the discussion is linked to the question of skills versus competencies, not only in the context of new digitized forms of measurement. Furthermore, a growing number of completely new or updated measurement procedures is about to reach the TVET sector in the context of the digitization of TEL (Köhler & Drummer, 2018; Hariyanto & Köhler, 2017). This study aimed at investigating the differences of the technical skills of voca

The microphthalmia with linear skin defects syndrome (MLS) is an X-linked dominant disorder with male lethality. In the majority of the patients reported, the MLS syndrome is caused by segmental monosomy of the Xp22.3 region. To date, five male patients with MLS and 46,XX karyotype (“XX males”) have been described. Here we report on the first male case with MLS and an XY complement. The patient showed agenesis of the corpus callosum, histiocytoid cardiomyopathy, and lactic acidosis but no microphthalmia, and carried a mosaic subtle inversion of the short arm of the X chromosome in 15% of his p

Gelatin is increasingly becoming an important raw material in many different fields. The pretreatment stage of the production of gelatin from pork skin plays an important role, it has big effect on the quality of obtained products. A survey on 5 types of acid HCl, H2SO4, H3PO4, CH3COOH, Citric was conducted. It showed that the influence of these types of acid on the pretreatment process was different. Acetic acid made the best result with the protein after extraction reaching 54.88 mg/ml, the product bloom reached 223. The most appropriate proportion of acetic acid was 3%. A survey on the effe

There is a worldwide development, better to say a non-development: We teach paper & pencil skills in primary schools almost like we did 30 or 50 or 100 years ago. Till today the primary school teachers spend up to more than 100 hours in the class room to teach and to train old fashioned algorithms though in daily life situations and for business purposes everybody uses a calculator. Why do we waste so much time of our children to teach them things which later on they will not need? We see an emotional dichotomy. Despite the research results from many research projects in many countries there s

Purpose – SUFUvet is a cross-disciplinary teaching-learning project designed to adapt students’ soft skills and track usability and the concrete surplus value of work techniques in the field of visual media design. Design/methodology/approach – For SUFUvet, a collaboration between the Institute of Food Hygiene/University of Leipzig and the Media Center/Technische Universität Dresden was initiated. Bachelor students of media informatics generate 3D visualisations in the framework of SCRUM: Undergraduate veterinary students issue instructions in order to create an e-learning class.

Dans cette thèse, nous nous intéressons au problème de la segmentation de portraits numériques. Nous appelons portrait numérique la photographie d’une personne avec un cadre allant grossièrement du gros plan au plan poitrine. Le problème abordé dans ce travail est un cas spécifique de la segmentation d’images où il s’agit notamment de définir précisément la frontière de la région « cheveux ». Ce problème est par essence très délicat car les attributs de la région « cheveux » (géométrie, couleur, texture) présentent une grande variabilité à la fois entre les personnes et au sein de la région.

Machine learning (ML) methods have been applied to the analysis of a range of biological systems. This thesis evaluates the application of these methods to the problem domain of skin permeability. ML methods offer great potential in both predictive ability and their ability to provide mechanistic insight to, in this case, the phenomena of skin permeation. Historically, refining mathematical models used to predict percutaneous drug absorption has been thought of as a key factor in this field. Quantitative Structure-Activity Relationships (QSARs) models are used extensively for this purpose. How

Vzrůstající nedostatek pohybu dětí a mladistvých v průmyslových státech se v minulých desetiletích rozvinul ve zdravotně-politický problém. V souladu s touto problematikou zároveň klesá i úroveň motorických schopností a dovedností, což představuje citelné omezení dětského vývoje, fyzické i psychické komponenty. Důsledkem jsou rostoucí náklady na zdravotní péči, které posléze výrazně zatěžují zdravotnictví v jednotlivých zemích.

Die Psoriasis ist eine meist schubweise verlaufende, chronisch-entzündliche Erkrankung der Haut. Sie ist genetisch determiniert und charakterisiert durch eine Dysregulation der Keratinozytenproliferation und der zellulären Immunabwehr. Patienten mit Psoriasis weisen meist noch weitere Begleiterkrankungen auf. So konnte in verschiedenen klinischen Studien ein Zusammenhang zwischen Psoriasis und Adipositas hergestellt werden. Die Zellen des weißen Fettgewebes sekretieren sowohl pro- als auch antiinflammatorische Mediatoren (Adipokine), die Einfluss auf verschiedene metabolische Prozesse und auch

Videotechnologien werden in der Lehrerbildung häufig eingesetzt, um die Lehrkompetenz zu fördern. Auch in der Fahrlehrerausbildung werden sie schon lange genutzt, hauptsächlich jedoch als Demonstrationsmaterial in Präsenzsitzungen. Eine aktiv-konstruktive Bearbeitung der Videos mit Hilfe digitaler Technologien findet nicht statt. Mittels internetgestützter Videoreflexion wurde im Rahmen eines EU-Projektes versucht, die Lehrkompetenz angehender Fahrlehrer zu fördern. Dabei hat sich gezeigt, dass ein Austausch unter den Ausbildern darüber, wie sie Videotechnologien in der Fahrlehrerausbildung ei
