Abstract:
BACKGROUND India is among one of the major tuberculosis (TB) endemic countries of the world. The Centers for Disease Control and Prevention (CDC) guidelines mandate early species identification of M. tuberculosis complex as an effective countermeasure. The conventional culture method, which is the ‘gold-standard’ technique of mycobacterial isolation is time consuming, while the newer, automated, liquid medium-based culture systems like BACT / ALERT 3D have considerably shorter detection time and greater sensitivity. Other than isolation it is also important to differentially identify Mycobacterium tuberculosis complex (MTBC) from nontuberculous mycobacteria (NTM). As MPT 64 antigen is specific for MTBC and can be detected with considerable accuracy it can be used as a tool to differentiate between MTBC and NTM. METHODS 200 samples (sputum, cerebrospinal fluid-CSF, pleural fluid etc.) in total were collected from clinically suspected smear negative patients. Each sample was inoculated both in L-J media and BACT / ALERT 3D system. Those samples which showed growth were further differentiated into MTBC and NTM both by conventional biochemical tests and MPT64 antigen detection kit test. RESULTS Out of the 200 samples, 30 produced growths. Lowenstein-Jensen (L-J) media detected 12 (40 %) and BACT / ALERT 3D system detected 26 (86.67 %) of the isolates. Among the 30 isolates, 18 (60 %) were MTBC and 12 (40 %) were NTM. Furthermore, L-J media detected 44.4 % and BACT / ALERT 3D system detected 88.9 % out of 18 MTBC isolates while among the 12 NTM isolates L-J media detected 33.33 % and BACT / ALERT 3D system detected 83.33 %. Mean detection time for MTBC was 46.5 days by L-J media and 20.8 days by BACT / ALERT 3D system. Mean detection time for NTM was 24.5 days by L-J media and 9.86 days by BACT / ALERT 3D system. Contamination rate in this study was 12 % in L-J media and 3 % in BACT / ALERT 3D system. We also found that for sensitivity, specificity, positive predictive value, negative predictive value of MPT64 antigen detection kit test was 100 % in our study considering biochemical tests as gold standard. CONCLUSIONS BACT / ALERT 3D system has a very good isolation rate and shorter mean detection time compared to L-J media even from smear negative samples. Also, MPT-64 antigen detection kit test is a very viable option to differentiate between MTBC and NTM. KEYWORDS MTBC, NTM, BACT / Alert 3D, MPT 64 Antigen

Abstract:
Introduction: We evaluated the efficacy of BacT/ALERT 3D culture medium in comparison with nested polymerase chain reaction (PCR) for early diagnosis of Mycobacterium tuberculosis (MTb) in cerebrospinal fluid (CSF). Methodology: A total of 50 clinically suspected patients with CSF findings suggestive of TBM (Tuberculous meningitis) and 20 healthy controls were included in the present study.CSF from each of the patient was inoculated in BacT/ALERT-MP culture media along with the culture on convention Lowenstein in Jensen’s medium. Simultaneously nested PCR was carried out both in CSF and growth positive above culture media targeting heat shock protein gene (hsp65), a conserved gene of MTb. Results: The culture showed 76% (38/50) positivity in TBM; however, 15% (3/20) of controls also showed false positivity by BacT/ALERT-MP system. By nested CSF-PCR, TBM could be detected in 92% (46/50)cases and 5% (1/20) in the controls. The other interesting observation was that when DNA isolated from broth of BacT/ALERT MP culture were subjected for PCR amplification, 15 (39.5%) of them yielded the desired amp icon for MTb while the broths subjected to conventional LJ media yielded for M. tuberculosis in 12 of the 38 bottles (31.5%). None of culture negative medium was positive by PCR. Sensitivity and specificity of BacT/ALERT MP culture considering all of them as real positive were 76% and 85% while for nested PCR the corresponding values were 92% and 95% respectively. Conclusions: BacT/ALERT 3D culture medium seems to be unsatisfactory as isolation sensitivity rate is very poor. Moreover, growth indicated in the medium must be confirmed for being Myco bacteria as other contaminants can also grow.DOI: http://dx.doi.org/10.3126/saarctb.v11i2.12429SAARC J TUBER LUNG DIS HIV/AIDS, 2014;XI(2),Page: 15-20

Abstract:
This work presents the design and construction of a laryngoscope model with camera vision that has a vibrating device to alert the medical specialist when the force exerted causes possible damage to the patient's airway during the intubation process. Design and fabrication considerations are described using Cast Material Position (FFD). The design is validated with the use of a high-fidelity simulator, the performance is compared with commercial models and the criteria of specialists are taken into account to improve all the necessary aspects. The model presented a great functional advantage, providing greater patient safety, reducing the risk of exposure of the internal tissue to high forces in the intubation process, facilitating clinical processes for health personnel.

Abstract:
Automated sensor based blood culture system is superior to traditional two steps or biphasic methods regarding time of isolation and avoiding contamination. The present study documented various aspects of blood culture isolates done in a well set automated system (BacT/ALERT 3D, BIOMERIUX, USA) at Dhaka city. As per monthly distribution of samples, number of samples showed increased trend from March and declining trend in November with peak in July, August, September and October. Average detection time was found as 20 hours. Among the bacterial pathogens isolated, Salmonella typhi was the most common (66.62%) followed by Salmonella paratyphi (S. paratyphi A & B 22.21%). Antibiotic susceptibility patterns (%) of the isolated organisms are shown in Table - VI. The results are not much divergent in respect of particular pathogens. The mostly focused results of common blood culture pathogen Salmonella typhi and Salmonella paratyphi show sensitivity pattern of over 95% towards Amoxyclav (98.0% & 99.36%), Aztreonam, Amikacin, Cefaclor, Cefixim, Cettazidime, Ceftriaxone, Cephalexine and Ciprofloxacin. Almost all the strains were found resistant towards Azithromycin. No satisfactory sensitivity was obtained towards Cotrimoxazole, Gentamicin, Mecillinam and Nalidixic acid. Gram negative bacteria including Escherichia coli as blood culture isolates were resistant towards used panel of antibiotics except Ciprofloxacin, Cotrimoxazole, Gentamicin and Mecillinam. Over 90% strains showed resistant towards Amoxycillin and Azithromycin. The study established that blood culture reports with positive growth and antimicrobial susceptibility can be generated within maximum of 72 hours by automated culture system.

Abstract:
In der vorliegenden Arbeit wurden neue Untersuchungsmöglichkeiten mit dem BacT/Alert 3D Mykobakterien-Testsystem erprobt. Erstens wurden Untersuchungen durchgeführt, um die Testkonzentrationen für Protionamid (PTH) und Linezolid (LIZ) für die standardmäßige Empfindlichkeitstestung von M. tuberculosis (Mtb) mit dem BacT/Alert 3D-System festzulegen. Dazu wurden die MHK-Werte für 32 Mtb-Stämme bestimmt: Referenzstamm Mtb H37Rv, sensible Patientenstämme, Patientenstämme mit verschiedenen Resistenzen (u. a. PTH-Resistenz) sowie eigens für die Arbeit isolierte LIZ-resistente Mutanten. Die PTH-MHK betrug für 20 von 21 sensiblen Mtb-Stämmen einschließlich des Referenzstammes Mtb H37Rv 0,125 - 1 mg/l (0,25 mg/l bei 11 von 21 Stämmen). Lediglich ein Stamm mit Resistenz gegenüber Isoniazid, Ethambutol und Streptomycin fiel mit einer etwas erhöhten PTH-MHK von 2 mg/l auf. Sechs PTH-resistente Stämme (z. T. mit anderen Resistenzen gegenüber Erstrang-Antituberkulotika) zeigten PTH-MHK von 4 - 16 mg/l. Die Gruppen der PTH-sensiblen und resistenten Stämme zeigten ein bimodales Verteilungsmuster, das mit einem Schwellenwert von 2 mg PTH/l gut zu differenzieren ist. Für die standardmäßige Durchführung der Empfindlichkeitstestung gegenüber PTH mit dem BacT/Alert 3D-System empfehlen wir deshalb eine PTH-Testkonzentration von 2 mg/l. Die LIZ-MHK betrug für 20 sensible Mtb-Stämme (inklusive Referenzstamm Mtb H37Rv) und sieben Stämme mit verschiedenen Resistenzen gegenüber Erstrang-Antituberkulotika 0,25 - 2 mg/l (0,5 mg/l bei 17 von 27 Stämmen). Für die vier isolierten LIZ-resistenten Mutanten betrug die LIZ-MHK 8 - 16 mg/l. Es zeigt sich auch bei der Verteilung der LIZ-MHK ein bimodales Verteilungsmuster; die Gruppen der sensiblen und resistenten Stämme sind gut zu differenzieren. Wir empfehlen für die standardmäßige Durchführung der Empfindlichkeitstestung gegenüber LIZ mit dem BacT/Alert 3D-System eine LIZ-Testkonzentration von 4 mg/l. Die festgestellten MHK-Werte von PTH und LIZ und die vorgeschlagenen Testkonzentrationen entsprechen Ergebnissen aus der Literatur, die mit ähnlichen Methoden erhoben wurden. Zweitens wurden mit dem BacT/Alert 3D-System Untersuchungen zur Kombinationstestung von Antituberkulotika bei Mtb und Stämmen des MAC-Komplexes durchgeführt, bisher liegen keine Publikationen für Untersuchungen von Wirkstoff-Kombinationen bei Mykobakterien mit diesem System vor. Es wurde geprüft, ob die MHK eines Antituberkulotikums durch die Zugabe einer subinhibitorischen Menge eines anderen Antituberkulotikums verändert wird. Bei Mtb wurden dazu folgende Kombinationen geprüft: Rifampicin (RMP) + LIZ, Moxifloxacin + LIZ, Isoniazid + PTH, RMP + PTH, PTH + LIZ. In keinem Fall konnten signifikante Effekte beobachtet werden. Ein tendenziell synergistischer Effekt der PTH-RMP-Kombination beim Stamm Mtb H37Rv (Reduktion der RMP-MHK um eine Stufe) wurde durch die Analyse der Wachstumskinetik des Stammes unterstützt. Bei zufällig ausgewählten Stämmen des MAC-Komplexes wurde die Kombination Ciprofloxacin (CIP) + Ethambutol (EMB) geprüft. Es zeigte sich bei sieben von zehn Stämmen eine Reduzierung der CIP-MHK um mindestens drei Stufen bei Zugabe einer subinhibitorischen Konzentration von EMB. Dieser synergistische Effekt wurde bereits in den 1990er Jahren mit einer ähnlichen Methode festgestellt, allerdings ohne die Stämme des MAC-Komplexes zu differenzieren (Arbeitsgruppe von S. Hoffner). Interessanterweise handelte es sich bei den von uns untersuchten Stämmen, bei denen dieser synergistische Effekt nachgewiesen wurde, um M. avium-Stämme. Diese Problematik sollte weiter verfolgt werden, da sich daraus Konsequenzen für die Therapieempfehlung ergeben könnten.

Abstract:
Increasing numbers of alerts produced by network intrusion detection systems (NIDS) have burdened the job of security analysts especially in identifying and responding to them. The tasks of exploring and analysing large quantities of communication network security data are also difficult. This thesis studied the application of visualisation in combination with alerts classifier to make the exploring and understanding of network security alerts data faster and easier. The prototype software, NSAViz, has been developed to visualise and to provide an intuitive presentation of the network security alerts data using interactive 3D visuals with an integration of a false alert classifier. The needs analysis of this prototype was based on the suggested needs of network security analyst's tasks as seen in the literatures. The prototype software incorporates various projections of the alert data in 3D displays. The overview was plotted in a 3D plot named as "time series 3D AlertGraph" which was an extension of the 2D histographs into 3D. The 3D AlertGraph was effectively summarised the alerts data and gave the overview of the network security status. Filtering, drill-down and playback of the alerts at variable speed were incorporated to strengthen the analysis. Real-time visual observation was also included. To identify true alerts from all alerts represents the main task of the network security analyst. This prototype software was integrated with a false alert classifier using a classification tree based on C4.5 classification algorithm to classify the alerts into true and false. Users can add new samples and edit the existing classifier training sample. The classifier performance was measured using k-fold cross-validation technique. The results showed the classifier was able to remove noise in the visualisation, thus making the pattern of the true alerts to emerge. It also highlighted the true alerts in the visualisation. Finally, a user evaluation was conducted to find the usability problems in the tool and to measure its effectiveness. The feed backs showed the tools had successfully helped the task of the security analyst and increased the security awareness in their supervised network. From this research, the task of exploring and analysing a large amount of network security data becomes easier and the true attacks can be identified using the prototype visualisation tools. Visualisation techniques and false alert classification are helpful in exploring and analysing network security data.

Abstract:
Es erfolgte die Re-Evaluierung der Empfindlichkeitstestung von Tuberkuloseerregern mit dem BacT/Alert-3D-System (bioMérieux) unter besonderer Berücksichtigung des Materialwechsels der Kulturflasche von Glas auf Plastik. Dazu wurden insgesamt 61 vergleichende MHK-Bestimmungen mit diesen beiden Flaschentypen durchgeführt, wobei sechs Antituberkulotika (INH, RMP, EMB, SM, PTH und MOX) sowie zwölf Mykobakterienstämme (davon neun Mtb.) untersucht wurden. Dabei findet sich kein Unterschied in den MHK-Werten zwischen Glas- und Plastikflaschen. Die Plastikflaschen sind folglich ebenso wie die Glasflaschen zur Empfindlichkeitstestung von Tuberkuloseerregern mit dem BacT/Alert-3D-System geeignet. Bei der bisherigen Methode wurde bei der PZA-Testung auf die Verwendung der Kontrollflasche zur Festlegung der Untersuchungszeit verzichtet, weil der erniedrigte pH-Wert ein unverhältnismäßig langsames oder gar fehlendes Wachstum in dieser Flasche bewirkt. Durch Optimierung von pH-Wert (pH 5,9) und PZA-Testkonzentration (200 mg/l) wurde erreicht, dass die PZA-Testung nach der gleichen Methode wie auch bei den anderen Antituberkulotika praktiziert, durchgeführt werden kann. Im weiteren wurde untersucht, wie hoch der Anteil resistenter Mutanten in Mischkulturen sein muss, um erkannt zu werden. Dazu wurden dem sensiblen Stamm H37Rv jeweils isogene Mutanten mit Monoresistenzen gegen INH, RMP oder SM bzw. EMB- und PZA-resistente Stämme in verschiedenen Anteilen zugesetzt. Es zeigte sich, dass ein Anteil von 1% resistenter Stämme noch nicht sicher detektiert wird
The purpose of this paper is to optimize and reevaluate the methods of susceptibility testing of M.tuberculosis with the BacT/Alert 3D System (bioMérieux). The key aspect was the comparison between culture bottles from glass between those made out of plastic material. Therefore 61 comparative MIC-tests were carried out, with six antituberculous drugs (INH, RMP; EMB, SM, PTH and MOX) and twelve mycobacterial strains (nine Mtb.) in order to compare the MIC in the two different bottle types. The MIC of 40 comparative tests between plastic culture bottles were identical to those in glass material. Only 18 test results deviated between the two bottle types. In each of those tests the discrepancy was only one degree of dilution, which is considered as not relevant. Resistant strains were found in three tests, with no difference between glass and plastic bottles. The deviant twelve results of Mtb. strains show a six times higher MIC-value in plastic bottles and a six times lower MIC in plastic bottles. In the case of the substance INH all four discrepant results had a higher MIC in the plastic bottle. Since these results were known by the Institut für Medizinische Mikrobiologie und Infektionsepidemiologie of the University Leipzig, it was consequently used with good results in the laboratory routine, as well as in external quality control (INSTAND-Ringversuche 2009 to 2011). The second topic of this study was to optimize the current method of susceptibility testing of Mtb. concerning pyrazinamide (PZA). In the current method the low pH of the dilution (5.5) with the resulting weak growth of the strains forced the laboratory assistant to abandon the 1% control bottle as endpoint of measurement. The new and optimized pH of 5.9 and a concentration of PZA of 200 mg/l allows the susceptibility testing of PZA with the same method as practiced for the other antituberculous drugs. Yet another focus of this study was the sensitivity of the BacT/Alert 3D System to detect heteroresistant clones in the mycobacterial broth. Resistant clones and fully susceptible Mtb. strain (H37Rv) were mixed in different percentages and susceptibility testing was performed. It could be shown, that a secure detection of resistant clones is not possible at a percentage 1% of resistant clones in the culture

Abstract:
Les changements anatomiques des patients au cours du traitement de radiothérapie peuvent engendrer des conséquences dosimétriques significatives sur les volumes cibles (VC) ou les organes à risques (OARs). Le processus de radiothérapie adaptative peut compenser ces variations, cependant son déploiement en clinique est ralentit par une charge de travail supplémentaire considérable pour les équipes médicales et aucun logiciel n'est disponible pour une utilisation en clinique. Nous avons développé un outil d'alerte dosimétrique in vivo simple permettant d'identifier rapidement les situations où une adaptation de traitement est requise pour un patient. L'évaluation dosimétrique des traitements délivrés a été réalisée sur l'imagerie embarquée 3D (CBCT) dont la précision des calculs de dose a dû être évaluée. L'outil d'alerte permet de s'affranchir d'une nouvelle délinéation de volumes d'intérêt et est basé sur des critères objectifs et quantifiables constitués par le dépassement des limites dosimétriques définies pour chacun des volumes considérés. La précision et la détectabilité de l'outil ont été validées puis il a été appliqué dans une étude rétrospective de 10 patients ORL afin de surveiller l'administration du traitement et d'identifier les patients pour lesquels une adaptation du traitement aurait pu être envisagée. Dans son implémentation clinique, le processus de radiothérapie adaptative requiert des algorithmes de recalage déformable capable de suivre les déformations locales d'un patient se produisant au cours du traitement, seulement leur utilisation n'est pas encore validée. Nous avons procédé à l'évaluation de la précision d'un algorithme de recalage déformable, de type Block Matching présentant l'avantage d'être adapté à l'imagerie multimodale CT/CBCT, en comparaison par rapport à un algorithme de recalage rigide. Une étude a été menée pour 10 patients ORL en se basant sur la comparaison de contours de volumes d'intérêt pour 76 CBCT. Les paramètres de similarité utilisés consistaient en l'Indice de Similarité Dice, la distance de Hausdorff robuste (en mm) et la différence de volume absolu (en cm3)
Changing anatomy during radiotherapy can lead to significant dosimetric consequences for organs at risk (OARs) and/or target volumes. Adaptive radiotherapy can compensate for these variations however its deployment for clinical work is hampered by the increased workload for the medical staff and there is still no commercialized software available for clinical use. We developed a simple in vivo dosimetric alert tool allowing rapid identification of patients who might benefit from an adaptive radiotherapy. Dosimetric evaluation of delivered treatment has been conducted onto 3D on board imaging (CBCT) whose dose calculation accuracy has been evaluated. The tool does not require a new volume of interest delineation. Tool alert is based on objectives and quantifiable criteria defined by the exceeding volumes of interest dose thresholds. Tool precision and detectability have been validated and applied in a retrospective study on 10 head and neck patients. The tool allows detecting patients where an adaptive treatment could have been considered. In its clinical implementation, adaptive radiotherapy process requires deformable matching algorithms to follow patient local's deformations occurring during treatment. Nevertheless, their use has not been validated. We conducted an evaluation of the Block Matching deformable algorithm, suitable for multimodality imaging (CT/CBCT), in comparison to rigid algorithm. A study has been conducted for 10 head and neck patients based on volume of interest contours comparison for 76 CBCT. Similarity parameters used consisted on Dice Similarity Index, Robust Hausdorff Distance (in mm) and the absolute volume difference (in cc)

Abstract:
The Necker cube is a widely known example of a reversible figure. Perceptual reversals were first observed in engravings of crystals by the Swiss geologist Louis Albert Necker in 1832. Although Necker’s engravings were not exactly of regular cubes, the figure as it is used now can be perceived in two alternative arrangements of a three-dimensional (3D) cube. Although less widely known than the popular two-dimensional version, the 3D Necker cube is a surprisingly rich model for psychophysical investigation. This chapter summarizes relevant main results and their implications for diverse theoretical issues such as the definition of visual illusions, the role of global three-dimensional interpretations in the integration of local sensory signals, and the exploratory and multisensory nature of perceptual processes.

Abstract:
Efficient sensor deployment has been one of the most challenging and interesting research areas. The importance and effectiveness of real-world sensing applications, such as underwater and atmospheric sensing, military applications, health systems, and alert systems, which target specific events, raise the need for adaptable design of Wireless Sensor Networks (WSNs). The main challenge in the design of such networks is the optimal sensor deployment, which helps extend the operational network lifetime. Indeed, by maintaining coverage and connectivity with the least number of active nodes and least communication cost, the operable time of the network is guaranteed to be prolonged. The study of two-dimensional (2D) WSNs introduced a significant advancement to the wireless sensor computing technology for different types of smart environments. Nevertheless, 2D WSNs were not sufficient concerning certain applications that require three-dimensional (3D) design. Previous work focused on the design and analysis of various approaches to cover a 3D field of interest, and expanded existing design from 2D to 3D space. Hence, the complexity of such approaches is a major stumbling block. To alleviate this problem, more efficient solutions for the design of WSNs for 3D space deployment have been introduced. By tessellation of the 3D space, which is one of the proposed solutions, researchers studied the partitioning of the space based on Voronoi tessellation by generating identical space-filling cells. Using space fillers cells, which are represented by polyhedra, to model the sensing range of the sensor nodes is assumed to be an optimal solution since these polyhedra can fill a 3D space without leaving gaps or overlaps among them. In the existing literature, the coverage problem in 3D space is concerned with finding the polyhedron that can best approximate the spherical sensing range and eliminates gaps without scarifying the network connectivity. Therefore, the latter is directly related to the sensor node placement strategy. This book chapter studies various proposed solutions for the design of 3D WSNs, with a focus on coverage and connectivity. More specifically, it presents several space filling polyhedra, including the cube, truncated octahedron, hexagonal prism, and rhombic dodecahedron. Also, it compares all these space filling polyhedra to cover a 3D space.

Abstract:
Abstract This work presents a sensor system to monitor environmental conditions in the vicinity of fuel storage tanks and facilities, providing measurements to help assess tank integrity and identify spills or leaks. The system utilizes a common hardware platform for multiple functional areas (e.g. base stations and sensing nodes) in the sensor network, simplifying manufacturing and logistics. The hardware platform was designed for low-cost manufacturing, adaptability, and versatility. It uses commercial off-the-shelf electronics in 3D-printed enclosures that were designed to optimize sensor and communication antenna placement. Pairing this hardware platform with a web-based data storage system and display client provides real-time telemetry visualization for monitoring tank facility conditions and can alert operators of potential leaks and hazards. The sensor system provides advances over current techniques in the form of scalability, cost minimization, live data reporting, and localization for active monitoring. Modularity reduces the engineering effort for adaptations to use new sensors in diverse environments, which can have different factors that lead to failures, and also allows the system to be updated as technology progresses. Data collected in experimental testing validates system functionality and ability to detect factors associated with spills and leaks.

Abstract:
ABSTRACT East Africa is an integral part of the Tullow business. Tullow has been active for over ten years in the onshore rift basins of East Africa, which began with the opening of the Uganda Lake Albert Rift Basin in 2006 following the drilling of Mputa-1. We developed multiple sub-surface evaluation tools and an understanding on how rift success factors can combine during the drilling of the Lake Albert Basin that we then applied to the Tertiary rifts of Kenya. Extensive Full Tensor Gradiometry (FTG), seismic and drilling has taken place over the last five years in Kenya. This has established the South Lokichar basin as a significant oil basin with significant remaining exploration upside. Up until 2015 exploration drilling in the South Lokichar utilized 2D seismic data. The acquisition of 3D seismic in the north and west of the basin has allowed an improved definition of the structural framework and highlighted additional exploration potential. The Etom-2 well spud in November 2015 highlights the value of this 3D seismic in complex structural settings. Etom-1 was planned and drilled on 2D seismic and encountered 10 m of oil pay. Subsequent re-mapping based upon the 3D seismic revealed that the Etom structure was more complicated than originally interpreted and that Etom-1 had drilled into a collapse graben and not tested the structural crest of the field. Etom-2 targeted the up-thrown northern fault block which was not penetrated by the Etom-1 well and encountered 102 m of oil pay. The northern part of the South Lokichar basin is structurally complex and the 3D seismic provided the required detail to highlight that Etom-1 hadn't properly tested the Etom structure. Further mapping of the 3D seismic in the area around Etom-2 has identified multiple follow-up prospects that could be part of a new play domain in the northern part of the South Lokichar Basin. These targets are the focus for Exploration drilling that is due to commence in Q4 2016.

Abstract:
Abstract This paper describes a system being developed for providing an optimized real-time decision support with automatic forward-looking and what-if simulations. It will address the challenge of achieving automation, better performance, and avoidance of non-productive time (NPT) in drilling operations. It will additionally address the demanding human support currently required in the entire decision support workflow. The approach includes utilization of Model based reasoning in Artificial Intelligence (AI) with a Digital Twin combined with Machine Learning (ML) and advanced 3D visualization which is a key enabler for operation alerts and optimization. Multiple forward-looking and what-if simulations will also be run in real-time to find optimal parameters for flow, rotation and running speed. A Diagnostic module will detect abnormalities and trigger safeguards. Auto-configuration and auto-calibration will be the key elements for Drilling Advisory system and deployment without the need for back-office support. The personnel involved in the operation (drilling contractor, service provider and operator) will be able to quickly provide the necessary operational input and then the system will be auto-calibrated during the operation. Results will be an Advisory Tool providing the operation with an optimal flow, rotation speed and running speed during Drilling, Tripping, Casing/liner/screen running and cement operations in two applications areas: In front of the driller as an Advisory tool for rigs with legacy drilling control systems not capable of receiving automated instructions. Base for providing direct commands and safeguards to rigs with control systems capable of receiving automated commands of optimal flow, rotation speed and running speed.

Abstract:
Wind turbines are classically designed for an extremely long lifetime in machinery design terms, for example, the Siemens SWT-6.0-154 was recently certified for 25 years [1]. The implication is that wind turbines accumulate damage via a number of mechanisms. A primary concern is naturally fatigue, exacerbated by a long life (high number of cycles); however, environmental effects such as bio-fouling and leading edge erosion damage the structure but also modify the Lift and Drag characteristics, particularly the stall behaviour. Vortex Generators (VGs), more commonly known from the aviation industry, have been demonstrated to delay stall and improve the stall region characteristics. This restoration of properties has been associated with reduced fatigue loading following the logic that the rotor blade will undergo stall less severely and less often. This hypothesis was tested in this study using a newly developed fatigue tool ALBdeS (named after W. Albert the first author to write a paper considering fatigue) to post-process aeroelastic simulations conducted in FAST (from NREL/NWTC) [2]. The post processing tool is an extension of the PMV custom section rotorblade analysis tool of SMART BLADE GmbH. The ALBdeS tool calculates the cumulative damage value in each individual layer of the blade section laminates and determines whether or not failure will occur over the course of 20 years, following the GL Guidelines [3]. Sensitivity studies showed that by de-constructing the main oscillation into 30 analysis points, the accumulated damage converges to a stable result, thus increasing confidence in the stability of the method. The FAST simulations were conducted with modified versions of the NREL 5MW reference turbine. The inboard lift and drag polars of the 5MW were modified in order to simulate the effect of adding VGs to the design. The polar modifications were made in the absence of 3D stall delay effects although literature does indicate the effects are somewhat additive. However, the resulting simulations did demonstrate that VGs did in fact change the fatigue characteristics of the rotor blades but by an inconsiderate amount.
