Abstract (sommario):
Accurate computation of joint angles from optical marker data using inverse kinematics methods requires that the locations of markers on a model match the locations of experimental markers on participants. Marker registration is the process of positioning the model markers so that they match the locations of the experimental markers. Markers are typically registered using a graphical user interface (GUI), but this method is subjective and may introduce errors and uncertainty to the calculated joint angles and moments. In this investigation, we use OpenSim to isolate and quantify marker registration–based error from other sources of error by analyzing the gait of a bipedal humanoid robot for which segment geometry, mass properties, and joint angles are known. We then propose a marker registration method that is informed by the orientation of anatomical reference frames derived from surface-mounted optical markers as an alternative to user registration using a GUI. The proposed orientation registration method reduced the average root-mean-square error in both joint angles and joint moments by 67% compared to the user registration method, and eliminated variability among users. Our results show that a systematic method for marker registration that reduces subjective user input can make marker registration more accurate and repeatable.

Abstract (sommario):
Elucidating marker-trait associations would have fruitful implications in distinctness, uniformity, and stability (DUS) tests of new varieties required for both variety registration and granting plant breeders’ rights. As the number of new varieties with narrow genetic bases increases, the necessity for deployment of molecular markers to complement morphological DUS traits gets particular attention. We used simple sequence repeats (SSRs) and sequence related amplification polymorphisms (SRAPs) markers in association mapping of morphological traits in a collection of 143 barley landraces and advanced breeding lines. This panel represented a diverse and uniform sample in terms of both quantitative and categorical traits whilst it was structurally partitioned by number of ear rows (six- and two-rowed) and seasonal growth habit (winter and spring types) characteristics. SSRs were more powerful compared with SRAPs in separating six- and two-rowed genotypes based on both model-based Bayesian and neighbor joining clustering methods. A number of associated SSR and SRAP markers were found for 15 out of 36 DUS traits after considering Bonferroni correction through linear models (GLM and MLM) and chi-square-based tests (SA and AAT). This is also the first report of association of awn roughness and grain color with molecular markers in barley. Moreover, SSR marker BMAC0113 appeared associated with time of ear emergence (TEE), confirming previous findings. These markers could be beneficial to complement and speed up DUS testing of new varieties, as well as for improving management of barley reference collections.

Abstract (sommario):
ABSTRACT OBJECTIVE To evaluate the effectiveness of implanted gold marker registration compared with bony fusion alignment for patient positioning using the Novalis Body system. METHODS Eighteen treatment fractions of stereotactic spinal radiotherapy were analyzed for three patients who each had three implanted gold seeds placed near their spinal lesions before radiotherapy. At each treatment session, the registration was first performed using bony fusion and then verified by another bony fusion, followed by registration with implanted markers. The software reported the calculated shifts for both methods. In addition, the actual three-dimensional coordinate positions of the markers were read using PTDReader software. Implanted marker positions were analyzed for variations in individual maker coordinate displacement, interseed distances, and area transcribed by them. Measured positional differences between the two fusion methods were applied to actual treatment plans to assess the resulting dosimetric differences in the treatment plans. RESULTS Both fusion algorithms were shown to localize the patient well, within 1.5 mm, but the implanted marker fusion consistently related less deviation from the planned isocenter, by approximately 0.5 mm, than did the bony fusion. Exceptions to this localization occurred when the average interseed distances were less than 3.0 cm and resulted in the two registration methods being equivalent. Implanted spine markers were also shown to have less than 0.7 mm deviation from the planned marker coordinates, indicating no migration of the seeds. Dose distributions were found to be highly dependant on differences in fusion method, with spinal cord doses up to 350% greater with bony fusion than with implanted markers. CONCLUSION Implanted markers used with the Novalis Body system have been shown to be more effective in patient positioning than the bony fusion method in the thoracic spine.

Abstract (sommario):
Object The aim of this study was to compare three patient-to-image registration methods in frameless stereotaxy in terms of their application accuracy (the accuracy with which the position of a target can be determined intraoperatively). In frameless stereotaxy, imaging information is transposed to the surgical field to show the spatial position of a localizer or surgical instrument. The mathematical relationship between the image volume and the surgical working space is calculated using a rigid body transformation algorithm, based on point-pair matching or surface matching. Methods Fifty patients who were scheduled to undergo a frameless image-guided neurosurgical procedure were included in the study. Prior to surgery, the patients underwent either computerized tomography (CT) scanning or magnetic resonance (MR) imaging with widely distributed adhesive fiducial markers on the scalp. An extra fiducial marker was placed on the head as a target, as near as possible to the intracranial lesion. Prior to each surgical procedure, an optical tracking system was used to perform three separate patient-to-image registration procedures, using anatomical landmarks, adhesive markers, or surface matching. Subsequent to each registration, the target registration error (TRE), defined as the Euclidean distance between the image space coordinates and world space coordinates of the target marker, was determined. Independent of target location or imaging modality, mean application accuracy (± standard deviation) was 2.49 ± 1.07 mm when using adhesive markers. Using the other two registration strategies, mean TREs were significantly larger (surface matching, 5.03 ± 2.30 mm; anatomical landmarks, 4.97 ± 2.29 mm; p < 0.001 for both). Conclusions The results of this study show that skin adhesive fiducial marker registration is the most accurate noninvasive registration method. When images from an earlier study are to be used and accuracy may be slightly compromised, anatomical landmarks and surface matching are equally accurate alternatives.

Abstract (sommario):
Small-animal models are used extensively in disease research, genomics research, drug development and developmental biology. The development of noninvasive small-animal imaging techniques with adequate spatial resolution and sensitivity is therefore of prime importance. In particular, multimodality small-animal imaging can provide complementary information. This paper presents a method for registering high-frequency ultrasonic (microUS) images with small-animal positron-emission tomography (microPET) images. Registration is performed using six external multimodality markers, each being a glass bead with a diameter of 0.43–0.60 mm, with 0.1 μl of [18F]FDG placed in each marker holder. A small-animal holder is used to transfer mice between the microPET and microUS systems. Multimodality imaging was performed on C57BL/6J black mice bearing WF-3 ovary cancer cells in the second week after tumor implantation and rigid-body image registration of the six markers was also performed. The average registration error was 0.31 mm when all six markers were used and increased as the number of markers decreased. After image registration, image segmentation and fusion are performed on the tumor. Our multimodality small-animal imaging method allows structural information from microUS to be combined with functional information from microPET, with the preliminary results showing it to be an effective tool for cancer research.

Abstract (sommario):
Objectives 1) Develop a less invasive but accurate enough registration strategy for otological surgical navigation. 2) Evaluate the new system in phantom study. 3) Evaluate the new system in cochlear implant surgeries. Methods A new registration method was developed for otologic surgery. Previously, the registration for accurate image-guided surgery often required invasive fiducial markers attached on patient's bone. We utilized the template of the bone surface to transfer the pre-made virtual bone-anchored markers to the patient's bone intraoperatively and eliminated the necessity for preoperative marker positioning or preoperative additional CT scan. Results We tested this Surface Template-Assisted Marker Positioning (STAMP) method using 5 temporal bone replicas, and in 5 ear surgeries (2 cochlear implants, 3 translabyrinthine acoustic neuroma surgeries) to investigate whether this method improves, or at least retains, the accuracy of image- guided surgery (IGS). The fiducial registration errors and target registration errors in the phantom study was ∼0.7 mm and ∼1.5 mm, respectively. The target registration errors in replicas were always less than 2 mm. In actual ear surgeries the fiducial registration errors were ∼0.6 mm and the target registration errors were less than 2 mm in 4 of 5 surgeries. All patients received successful cochlear implantation or tumor removal. Conclusions The new method reduced the preoperative procedures for patients but did not reduce the accuracy of the surgical navigation. Our method would be a useful IGS method in the field of otology where both accuracy and non-invasiveness are required.

Abstract (sommario):
Objective: Navigation systems create a connection between imaging data and intraoperative situs, allowing the surgeon to consistently determine the location of instruments and patient anatomy during the surgical procedure. The best results regarding the target registration error (measurement uncertainty) are normally demonstrated using fiducials. This study aimed at investigating a new registration strategy for an electromagnetic navigation device. Methods: For evaluation of an electromagnetic navigation system and comparison of registration with screw markers and automatic registration, we are calculating the target registration error in the region of the paranasal sinuses/anterior and lateral skull base with the use of an electromagnetic navigation system and intraoperative digital volume tomography (cone-beam computed tomography). We carried out 10 registrations on a head model (total n = 150 measurements) and 10 registrations on 4 temporal bone specimens (total n = 160 measurements). Results: All in all, the automatic registration was easy to perform. For the models that were used, a significant difference between an automatic registration and the registration on fiducials was evident for just a limited number of screws. Furthermore, the observed differences varied in terms of the preferential registration procedure. Conclusion: The automatic registration strategy seems to be an alternative to the established methods in artificial and cadaver models of intraoperative scenarios. Using intraoperative imaging, there is an option to resort to this kind of registration as needed.

Abstract (sommario):
AbstractThe motility of the gastrointestinal tract is crucial for digestive activity and dysfunction can lead to severe disease pattern. A method for analysing the motility is needed when treatment approaches shall be evaluated. Therefore markers attached to different locations on the stomach and the bowel of pigs are video tracked in this research study. The markers are designed to provide a high contrast and have an adhesive side for fixation. Above the operation field a video camera has been placed to film the markers during the procedure. To analyse the video data a special algorithm has been implemented. The algorithm requires a registration process at the beginning of each recording which allows the parallel tracking of multiple markers. After the registration the algorithm tracks the position of the marker frame by frame. Each frame is converted into a greyscale picture by adding specified colour values of each pixel. This allows emphasizing certain colours. The centre of the marker is determined by computing the horizontal and vertical centre of the marker starting at the corresponding marker position of the previous frame. After completion the data is stored as coordinates and a video with the marker position displayed for further processing. For advanced analysis the data can be synchronized with electromyography signals, for example. The marked videos show a promising tracking of the markers. However, if the algorithm loses track of a marker during a recording, it is unlikely to relocate it due to the successive processing of the frames. Nevertheless this method provides a simple and easy to use solution for movement detection of the gastrointestinal tract.

Abstract (sommario):
Computer-assisted navigation plays an important role in modern craniomaxillofacial surgery. Although headpins and skull posts are widely used for the fixation of the reference frame, they require the use of invasive procedures. Headbands are easily displaced intraoperatively, thus reducing the accuracy of the surgical outcome. This study reported the utility of a novel splint integrated with a reference frame and registration markers for maxillary navigation surgery. A maxillary splint with a 10 cm resin handle was fabricated before surgery, to fix the reference frame to the splint. The splint was set after the incorporation of fiducial gutta-percha markers into both the splint and resin handle for marker-based pair-point registration. A computed tomography (CT) scan was acquired for preoperative CT-based planning. A marker-based pair-point registration procedure can be completed easily and noninvasively using this custom-made integrated splint, and maxillary navigation surgery can be performed with high accuracy. This method also provides maximum convenience for the surgeon, as the splint does not require reregistration, and can be removed temporarily when required. The splint-to-CT data registration strategy has potential applicability not only for maxillary surgery but also for otolaryngologic surgery, neurosurgery, and surgical repair after craniofacial trauma.

Image-guided neurosurgery interventions are becoming sur- gical procedure routines. We suggest a novel method for automatic marker localization in X-ray images for Leksell SurgiPlan® which is an image-based neurosergical treat- ment planning software provided by Elekta Instrument AB. We implemented an algorithm for fiducial marker localiza- tion based on feature detection, classification and prior geo- metrical knowledge of the markers. Automatic localization ca help to decrease the human error associated with manual registration of these fiducial markers which is the current applied method for X-ray images in Leksell SurgiPlan®.

Abstract (sommario):
The aim of the present thesis is to provide an e ffective computational framework for the analysis and quantifi cation of the longitudinal structural changes in Alzheimer's disease (AD). The framework is based on the diffeomorphic non-rigid registration parameterized by stationary velocity fields (SVFs), and is hierachically developed to account for the diff erent levels of variability which characterize the longitudinal observations of T1 brain magnetic resonance images (MRIs). We developed an effi cient and robust method for the quantifi cation of the structural changes observed between pairs of MRIs. For this purpose, we propose the LCC-Demons registration framework which implements the local correlation coeffi cient as similarity metric, and we derived consistent and numerically stable measures of volume change and boundary shift for the regional assessment of the brain atrophy. In order to consistently analyze group-wise longitudinal evolutions, we then investigated the parallel transport of subject-specifi c deformation trajectories across di fferent anatomical references. Based on the SVF parametrization of diffeomorphisms, we relied on the Lie group theory to propose new and effective strategies for the parallel transport of SVFs, with particular interest into the practical application to the registration setting. These contributions are the basis for the defi nition of qualitative and quantitative analysis for the pathological evolution of AD. We proposed several analysis frameworks which addressed the di fferentiation of pathological evolutions between clinical populations, the statistically powered evaluation of regional volume changes, and the clinical diagnosis at the early/prodromal disease stages.

Abstract (sommario):
Le cancer de la prostate est le cancer le plus fréquent chez l'homme en Europe, néanmoins il n'existe actuellement pas de technique d'imagerie permettant de détecter avec précision les tumeurs dans la glande. Sachant que les coupes histologiques contiennent la réalité de terrain concernant le diagnostic, il est nécessaire de recaler les images de chaque technique d'imagerie aux coupes histologiques afin de pouvoir les évaluer. De plus, comme il n'existe pas de méthode permettant de contrôler précisément le plan de coupe histologique, le recalage doit être considéré comme un problème 3D. Un dispositif permettant de réaliser, de manière rapide et standardisée, des marqueurs internes dans les coupes histologiques a été développé, de même qu'un algorithme permettant de détecter automatiquement ces marqueurs, de les identifier et d'aligner les coupes histologiques. La méthode a été testée sur 10 prostates, avec en moyenne 19.2 coupes par prostate, et a permis d'obtenir une précision de recalage moyenne de 0.18 ± 0.13 mm au niveau des marqueurs. Un deuxième algorithme a été développé pour recaler les coupes histologiques, une fois alignées, avec les images IRM. Ce recalage a été conçu pour être guidé par les canaux éjaculateurs, un repère anatomique présent dans chaque prostate et visible à la fois en histologie et dans les images IRM cliniques, acquises avec une résolution standard. L'algorithme a d'abord été testé en s'appuyant sur les marqueurs artificiels. La précision obtenue pour le recalage était en moyenne de 0.45±0.25 mm au niveau des marqueurs et de 1.04 ± 0.21 mm au niveau des canaux éjaculateurs. L'algorithme a enfin été testé en guidant le recalage à l'aide de la position des canaux éjaculateurs. La précision moyenne obtenue était alors de 0.16±0.05 mm au niveau des canaux éjaculateurs et de 2.82±0.41 mm au niveau des marqueurs. Ces résultats suggèrent une valeur du facteur de rétrécissement de l'ordre de 1.07±0.03 et une inclinaison vis à vis du plan de coupe histologique de l'ordre de 13.6◦ ± 9.61◦, avec une variance importante pour ces deux paramètres
Prostate cancer is the most frequently diagnosed cancer of men in Europe, yet no current imaging technique is capable of detecting with precision tumours in the prostate. The histology slices are the gold standard for the diagnosis. Therefore, in order to evaluate each imaging technique, the histology slices must be precisely registered to the imaged data. As it cannot be assumed that the histology slices are cut along the same plane as the imaged data is acquired, the registration must be considered as a 3D problem. An apparatus has been developed that enables internal fiducial markers to be created in the histology slices in a rapid and standardised manner. An algorithm has been developed that automatically detects and identifies these markers, enabling the alignment of the histology slices. The method has been tested on 10 prostate specimens, with 19.2 slices on average per specimen. The accuracy of the alignment at the fiducial markers was on average 0.18±0.13 mm. A second algorithm was developed to 3D register the aligned histology slices with the MR images. The registration is designed to be guided by the ejaculatory ducts, an anatomical landmark present in every prostate and visible in both histology and MR images acquired at standard clinical resolution. The algorithm was first tested by using the fiducial needles to guide the registration. The average registration accuracy was 0.45 ± 0.25 mm at the fiducial needles and 1.04±0.21 mm at the ejaculatory ducts. The algorithm was then tested by using the ejaculatory ducts to guide the registration. The average registration accuracy was 0.16±0.05 mm at the ejaculatory ducts and 2.82 ± 0.41 mm at the fiducial needles. The results suggest that the histology shrinkage factor is of the order 1.07±0.03 and the tilt of the histology slicing plane is 13.6◦ ±9.61◦, with both parameters showing significant variance

Abstract (sommario):
Proteins are the actual actors in the (normal or disrupted) physiological processes and immunohistochemistry (IHC) is a very efficient mean of visualizing and locating protein expression in tissue samples. By comparing pathologic and normal tissue, IHC is thus able to evidence protein expression alterations. This is the reason why IHC plays a grow- ing role to evidence tissue-based biomarkers in clinical pathology for diagnosing var- ious diseases and directing personalized therapy. Therefore, IHC biomarker evaluation significantly impacts the adequacy of the therapeutic choices for patients with serious pathologies, such as cancer. However, this evaluation may be time-consuming and dif- ficult to apply in practice due to the absence of precise positive cut-off values as well as staining (i.e. protein expression) heterogeneity intra- and inter-samples. Quantifying IHC staining patterns has thus become a crucial need in histopathology. For this task, automated image analysis has multiple advantages, such as avoiding the evidenced ef- fects of human subjectivity. The recent introduction of whole-slide scanners opened a wide range of possibilities for addressing challenging image analysis problems, includ- ing the identification of tissue-based biomarkers. Whole-slide scanners are devices that are able to image whole tissue slides at resolutions up to 0.1 micrometers per pixels, often referred to as virtual slides. In addition to quantification of IHC staining patterns, virtual slides are invaluable tools for the implementation of digital pathology work- flows. The present work aims to make several contributions towards this current digital shift in pathology. Our first contribution was to propose an automated virtual slide sharpness assessment tool. Although modern whole-slide scanner devices resolve most image standardization problems, focusing errors are still likely to be observed, requiring a sharpness assessment procedure. Our proposed tool will ensure that images provided to subsequent pathologist examination and image analysis are correctly focused. Virtual slides also enable the characterization of biomarker expression heterogeneity. Our sec- ond contribution was to propose a method to characterize the distribution of densely stained regions in the case of nuclear IHC biomarkers, with a focus on the identification of highly proliferative tumor regions by analyzing Ki67-stained tissue slides. Finally, as a third contribution, we propose an efficient mean to register virtual slides in order to characterize biomarker colocalization on adjacent tissue slides. This latter contribution opens new prospects for the analysis of more complex questions at the tissue level and for finely characterizing disease processes and/or treatment responses./Les protéines sont les véritables acteurs des processus physiologiques (normaux ou per- turbés) et l’immunohistochimie (IHC) est un moyen efficace pour visualiser et localiser leur expression au sein d’échantillons histologiques. En comparant des échantillons de tissus pathologiques et normaux, l’IHC permet de révéler des altérations dans des pro- fils d’expression protéique. C’est pourquoi l’IHC joue un rôle de plus en plus important pour mettre en évidence des biomarqueurs histologiques intervenant dans le diagnos- tic de diverses pathologies et dans le choix de thérapies personnalisées. L’évaluation de l’expression de biomarqueurs révélés par IHC a donc des répercussions importantes sur l’adéquation des choix thérapeutiques pour les patients souffrant de pathologies graves, comme le cancer. Cependant, cette évaluation peut être chronophage et difficile à appliquer en pratique, d’une part, à cause de l’hétérogénéité de l’expression protéique intra- et inter-échantillon, d’autre part, du fait de l’absence de critères de positivité bien définis. Il est donc devenu crucial de quantifier les profils d’expression de marquages IHC en histopathologie. A cette fin, l’analyse d’image automatisée possède de multiples avantages, comme celui d’éviter les effets de la subjectivité humaine, déjà démontrés par ailleurs. L’apparition récente des numériseurs de lames histologiques complètes, ou scanners de lames, a permis l’émergence d’un large éventail de possibilités pour traiter des problèmes d’analyse d’image difficiles menant à l’identification de biomar- queurs histologiques. Les scanners de lames sont des dispositifs capables de numériser des lames histologiques à une résolution pouvant atteindre 0,1 micromètre par pixel, expliquant la dénomination de "lames virtuelles" des images ainsi acquises. En plus de permettre la quantification des marquages IHC, les lames virtuelles sont des outils indis- pensables pour la mise en place d’un flux de travail numérique en pathologie. Le travail présenté ici vise à fournir plusieurs contributions au récent changement de cap vers une numérisation de la discipline médicale qu’est l’anatomie pathologique. Notre première contribution consiste en un outil permettant d’évaluer automatiquement la netteté des lames virtuelles. En effet, bien que les scanners de lames résolvent la plupart des pro- blèmes liés à la standardisation de l’acquisition, les erreurs de focus restent fréquentes, ce qui nécessite la mise en place d’une procédure de vérification de la netteté. L’outil que nous proposons assurera la netteté des images fournies à l’examen du pathologiste et à l’analyse d’image. Les lames virtuelles permettent aussi de caractériser l’hétérogénéité de l’expression de biomarqueurs. Ainsi, la deuxième contribution de ce travail repose sur une méthode permettant de caractériser la distribution de régions densément marquées par des biomarqueurs IHC nucléaires. Pour ce travail, nous nous sommes concentrés sur l’identification de régions tumorales présentant une forte activité proliférative en analysant des lames virtuelles révélant l’expression de la protéine Ki67. Finalement, la troisième contribution de ce travail fut de proposer un moyen efficace de recaler des lames virtuelles dans le but de caractériser la colocalisation de biomarqueurs IHC révé- lés sur des coupes de tissu adjacentes. Cette dernière contribution ouvre de nouvelles perspectives pour l’analyse de questions complexes au niveau histologique ainsi que la caractérisation fine de processus pathologiques et de réponses thérapeutiques.

Abstract (sommario):
The purpose of this thesis is to examine the problem of gazumping, to consider the various factors which give rise to it, to examine the adequacy of existing legal doctrine in redressing it, to explore statutory provisions designed to reduce gazumping and to propose reform of the law to address the problem. The term gazumping refers to a practice by which a vendor accepts a purchaser's offer to purchase land or property, and before exchanging contracts, withdraws from the existing agreement in order to accept a higher price from another purchaser. This thesis proceeds on the assumption that gazumping is an undesirable practice, particularly from the prospective purchaser' perspective. The practice of gazumping initially boomed in a volatile property market with constantly rising house prices and where demand exceeded supply. A purchaser who believes he or she has secured the purchase of his or her desired property may suffer emotional stress and significant costs which cannot be recovered when the vendor reneges on his or her agreement. The thesis notes that gazumping occurs at the pre-contractual stage in the sale of property because there is no legally binding relationship before the formal exchange of contracts. The thesis posits that the existing law in various Australian jurisdictions offers inadequate protection to prospective purchasers of property. The thesis examines the inadequacy of existing legal doctrines and remedies in addressing the problem of gazumping at the pre-contractual stage and arrives at the conclusion that existing legal doctrine is inadequate. The thesis notes legislative and other measures in response to gazumping in Australia and other common law jurisdictions and concludes that these too were inadequate in not going far enough to eliminate or reduce gazumping. The competing merits of these approaches are considered. The thesis establishes that the solution to gazumping lies in an early protection of the purchaser�s interest in land. This is because as soon as an agreement is enforceable the purchaser acquires an equitable interest and in the event of any breach of the agreement by the vendor, the purchaser, as a general rule, can obtain either damages or specific performance. The thesis raises seven key recommendations for law reform aimed to minimise the occurrence of gazumping and to provide the purchaser with tools against the practice of gazumping. It considers that the recommendations can minimise the undesirable practice of gazumping where the current law is inadequate and also achieve several other objectives.

Abstract (sommario):
The harmonisation of the European Trade Mark laws and the introduction of unconventional marks under this regime have encouraged interested parties to seek registration of chemical senses (scent and taste) as trade marks. This thesis studies the current state of affairs of these types of marks. It discusses in general, the panorama that these types of marks have when registrability is at issue. The purpose of this research is therefore to scrutinise the trade mark legal system, including a discussion of the origins and rationale underlying it, to try to understand the burdens presented when registering chemical sense marks. The starting point of this thesis is that the European Regulation and the Directive of the Trade Mark law open the door to the protection of chemical senses under the Trade Mark law regime. Yet, despite some early successful registration, their fate is still burdened with uncertainty and therefore the rationale for this study is to try to find whether chemical sense marks are truly marks and therefore protectable under the trade mark system. The approach chosen addresses the examination of all requirements for a sign to be protected under the trade mark system. The reason is that protection of chemical senses might be granted if such marks are recognised as signs, are graphically represented and are capable of distinguishing products of one undertaking from those of another undertaking. By examining the aforementioned requirements, the study reveals that while chemical senses marks might be seen as marks, they find that registration is not quite feasible. The thesis emphasises that graphic representation is only one of the many issues that chemical sense marks are confronted with. Issues such as distinctiveness, the need to keep free and functionality remain problematic. Moreover, the scope of protection afforded to chemical sense marks are yet untested. Case law will ascertain that the intent behind the trade mark regime to grant registration to chemical senses is unresolved. Still, the significant interest in chemical senses as trade marks appears to be not softening by this notion.

Abstract (sommario):
Bildgesteuerte, perkutane Interventionen stellen bei vielen diagnostischen und therapeutischen Fragestellungen eine Alternative zum chirurgischen Vorgehen dar. Hierbei kommen bevorzugt die Sonographie und die Computertomographie (CT) zum Einsatz. Zu den Indikationen für eine gezielte Nutzung der Magnetresonanztomographie (MRT) zählen Befunde, die sich mit anderen Modalitäten nicht ausreichend darstellen lassen, die fehlende Strahlenexposition (CT) sowie Alleinstellungsmerkmale wie der hervorragende native Weichteilkontrast oder die Möglichkeiten zur Darstellung von Temperaturen oder Diffusionsprozessen. Zu den Nachteilen zählen die langen Messzeiten, das starke Magnetfeld sowie die räumliche Enge in den meist röhrenförmigen Geräten, die ein interventionelles Vorgehen oft erschweren. Stereotaktische Führungs- und Navigationshilfen sind kein notwendiger Bestandteil der interventionellen Ausrüstung, ermöglichen jedoch oft eine gezieltere Planung, bessere Visualisierung oder vereinfachte Durchführung, insbesondere gegenüber einer rein kognitiven Einbeziehung der MRT-Informationen. Assistenzsysteme für geschlossene MRT-Geräte sind meist rahmenbasiert und beschränken sich auf bestimmte Regionen, z. B. die Mamma, die Prostata oder das muskuloskelettale System. Diese Arbeit beschreibt hingegen eine leistungsstarke rahmenlose Assistenztechnik (Navigation), die sich praktisch in beliebigen Körperregionen einsetzen lässt. Der Operateur orientiert sich dabei anhand von hochwertigen MRT-Ansichten, die gemäß der in Echtzeit erfassten Nadellage aus einem kurz zuvor erhobenen Referenzdatensatz reformatiert werden. Ausgehend von der Implementierung an einem speziellen offenen MRT-System (0,5 T) werden interventionelle Komponenten und Methoden beschrieben, die erfolgreich auf ein herkömmliches MRT-System (1,5 T) übertragen wurden. Die Einschränkungen des geschlossenen Systems führten dabei zu einer speziellen Registrierungstechnik mit Hilfe einer kompakten, frei positionierbaren Referenzplatte mit resonanten Miniatur-Hochfrequenzspulen (semiaktiv) als MR-Positionsmarker. Im Vordergrund stand die systematische Prüfung der Marker hinsichtlich Signalverhalten und Sicherheit sowie die Zuverlässigkeit und Genauigkeit einer vollautomatischen, bildbasierten 3D-Lokalisation unter experimentellen und klinischen Randbedingungen. Gegenüber herkömmlichen, passiven (Kontrastmittel-) Markern zeichnet sich die semiaktive Technik dadurch aus, dass sie gleichzeitig, auch mehrere, beliebig über das gesamte Messvolumen verteilte Marker, praktisch unabhängig von sämtlichen anatomischen Strukturen lokalisieren kann. Sowohl die Festlegung einer Position (ein Marker) oder einer Ebene (drei Marker) wie auch die navigierte Platzierung einer Nadel zeigten im Experiment ausreichend hohe Genauigkeiten. Auf Basis einer zeitlich optimierten (Subsekunden-) Markerbildgebung konnte experimentell eine robotisch geführte Nadel direkt im MRT bildgebend verfolgt werden, was weitere Anwendungen der Lokalisationstechnik in Aussicht stellt. Navigierte Biopsien an einem Gewebephantom zeigten nach ausschließlich stereotaktischer Positionierung – ohne Kontrollbildgebung – unabhängig vom Erfahrungsgrad der medizinischen Anwender ausreichend hohe Trefferquoten. Gleichzeitig lieferte die Studie wertvolle, auch anwenderspezifische Erkenntnisse über die Bedienbarkeit sowie den Zeitbedarf für einzelne Interventionsschritte. Im Vergleich mit anderen prototypischen oder kommerziellen Systemen zeigte sich die vorgestellte Assistenztechnik – am Beispiel muskuloskelettaler Interventionen – als klinisch flexibel einsetzbar.

Abstract (sommario):
Traditional trade marks, such as words and figures, have for a long time constituted of visual signs. However, due to the evolution of modern technology and changing marketing methods, non-traditional trade marks have been increasing in todays highly competitive market.1 Consequently, the evolution created legal uncertainties in the European Union (EU) since in order to register a trade mark, it had to be represented graphically. This requirement was difficult to achieve for some non-traditional trade marks which were perceived through other sensed than the sight. On the 1 October 2017, requirement for graphical representation has been amended in the EU Trade Mark Regulation 2017/10012 by a technical neutral requirement which opens up possibilities for registration of European Union trade marks in a more suitable way, using generally available technology. The purpose of this thesis has been to analyse how the abolition of graphical representation and the new wider requirement will affect the registration of non-traditional trade marks in the EU. Signs which have been analysed in the frame of this thesis are: sound, olfactory, three-dimensional, colour, motion, multimedia, holograms, pattern, tactile and taste marks. Conclusively, I found that the technical neutral registration requirement has opened up possibilities for trade mark holders to register new types of marks like multimedia marks. Moreover, it has simplified the registration process for already accepted non-traditional trade marks such as hologram, motion and sound marks. However, the reform has hardly affected the registration process of colour, pattern and three-dimensional marks since their biggest challenge with the registration have been the requirement for distinctiveness. Furthermore, it is currently still not possible to register olfactory, tactile and taste marks. Though the new and flexible amendments indicate that those types of marks may be more easily registered in the future.

Abstract (sommario):
When studying human kinematics, the intention is usually to isolate and model the movements of bony segments. With motion capture based on skin mounted marker systems, there is confounding of the extent to which the surface represents the movements of the underlying bony structures1 . Soft tissue artifact (STA) is an important confounder, caused by the relative movement between the skin mounted markers and the underlying bones. STA is a commonly encountered problem in biomechanics2 . Furthermore, for applications such as motion analysis of composite joints in the spine, wrist and ankle, the inability to associate surface markers closely with underlying bony segments has inhibited the construction of meaningful mechanical models3. The research question underpinning this program of work is whether it may be possible to use data from cross sectional imaging modalities in combination with surface mounted marker sets, to solve for the error associated with surface markers and so produce refined functional models of activities in real world settings.

Abstract (sommario):
Abstract This paper proposes an augmented reality (AR) framework and tool on smartphones as an alternative to conventional inspection for AM parts. The framework attempts to introduce the rapid inspection potential of smartphone based AR within manufacturing by leveraging the manufacturing capability of additive manufacturing (AM) to integrate markers onto AM parts. The key step from this framework that is explored in this paper is the design and quality assessment of AM markers for marker registration. As part of the marker design and quality assessment objectives, this research conducts an evaluation on the effects of different AM processes on the quality of augmentation achieved from AM fiducial markers. Furthermore, it evaluates the minimum fiducial pattern size that on integration onto AM parts will be viable for augmentation. The results suggest that the AM process and the size of the fiducial pattern play a significant role in determining the quality of the AM markers. The paper concludes by stating that dual material extrusion AM markers provide the highest number of detectable features and therefore the highest quality of AM markers, and the smallest viable fiducial pattern for Cybercode/QR code marker can be sized at 19 × 19mm2.

Abstract (sommario):
In the article investigational three magazines which went out after Second World war in Germany and Austria in the environment of the Ukrainian emigrants, is «Theater» (edition of association of artists of the Ukrainian stage), «Student flag» (a magazine of the Ukrainian academic young people is in Austria), «Young friends» (a plastoviy magazine is for senior children and youth). The thematic structure of magazines, which is inferior the association of different on age, is considered, by vital experience and professional orientation of people in the conditions of the forced emigration, paid regard to graphic registration of magazines, which, without regard to absence of the proper publisher-polydiene bases, marked structuralness and expressiveness. A repertoire of periodicals of Ukrainian migration is in the American, English and French areas of occupation of Germany and Austria after Second world war, which consists of 200 names, strikes the tipologichnoy vseokhopnistyu and testifies to the high intellectual level of the moved persons, desire of yaknaynovishe, to realize the considerable potential in new terms with hope on transference of the purchased experience to Ukraine. On ruins of Europe for two-three years the network of the press, which could be proud of the European state is separately taken, is created. Different was a period of their appearance: from odnogo-dvokh there are to a few hundred numbers, that it is related to intensive migration of Ukrainians to the USA, Canada, countries of South America, Australia. But indisputable is a fact of forming of conceptions of newspapers and magazines, which it follows to study, doslidzhuvati and adjust them to present Ukrainian realities. Here not superfluous will be an example of a few editions on the thematic range of which the names – «Plastun» specify, «Skob», «Mali druzi», «Sonechko», «Yunackiy shliah», «Iyzhak», «Lys Mykyta» (satire, humour), «Literaturna gazeta», «Ukraina і svit», «Ridne slovo», «Hrystyianskyi shliah», «Golos derzhavnyka», «Ukrainskyi samostiynyk», «Gart», «Zmag» (sport), «Litopys politviaznia», «Ukrains’ka shkola», «Torgivlia i promysel», «Gospodars’ko-kooperatyvne zhyttia», «Ukrainskyi gospodar», «Ukrainskyi esperantist», «Radiotehnik», «Politviazen’», «Ukrainskyi selianyn» Considering three riznovektorni magazines «Teatr» (edition of Association Mistciv the Ukrainian Stage), «Studentskyi prapor» (a magazine of the Ukrainian academic young people is in Austria), «Yuni druzi» (a plastoviy magazine is for senior children and youth) assert that maintenance all three magazines directed on creation of different on age and by the professional orientation of national associations for achievement of the unique purpose – cherishing and maintainance of environments of ukrainstva, identity, in the conditions of strange land. Without regard to unfavorable publisher-polydiene possibilities, absence of financial support and proper encouragement, release, followed the intensive necessity of concentration of efforts for achievement of primary purpose – receipt and re-erecting of the Ukrainian State.
