Abstract (sommario):
Abstract:Electrical stimulation-induced leg muscle contractions provide a useful model for examining the role of leg muscle neural afferents during low-intensity exercise in persons with spinal cord-injury and their able-bodied cohorts. Eight persons with paraplegia (SCI) and 8 non-disabled subjects (CONTROL) performed passive knee flexion/extension (PAS), electrical stimulation-induced knee flexion/extension (ES) and voluntary knee flexion/extension (VOL) on an isokinetic dynamometer. In CONTROLS, exercise heart rate was significantly increased during ES (94 ± 6 bpm) and VOL (85 ± 4 bpm) over PAS (69 ± 4 bpm), but no changes were observed in SCI individuals. Stroke volume was significantly augmented in SCI during ES (59 ± 5 ml) compared to PAS (46 ± 4 ml). The results of this study suggest that, in able-bodied humans, Group III and IV leg muscle afferents contribute to increased cardiac output during exercise primarily via augmented heart rate. In contrast, SCI achieve raised cardiac output during ES leg exercise via increased venous return in the absence of any change in heart rate.

Abstract (sommario):
Several high-tech manufacturing technologies are emerging to meet the demand for mass customized products. These technologies include configurable robots, augmented reality and the Internet-of-Things. Manufacturing enterprises can leverage these new technologies to pursue increased flexibility, i.e., the ability to perform a larger variety of activities within a shorter time. However, the flexibility offered by these new technologies is not fully exploited, because current operations management techniques are not dynamic enough to support high variability and frequent change. The HORSE Project investigated several of the new technologies to find novel ways to improve flexibility, as part of the Horizon 2020 research and innovation program. The purpose of the project was to develop a system, integrating these new technologies, to support efficient and flexible manufacturing. This article presents the core result of the project: a reference architecture for a manufacturing operations management system. It is based on the application and extension of business process management (BPM) to manage dynamic manufacturing processes. It is argued that BPM can complement current operations management techniques by acting as an orchestrator in manufacturing processes augmented by smart technologies. Building on well-known information systems’ architecting frameworks, design science research is performed to determine how BPM can be applied and adapted in smart manufacturing operations. The resulting reference architecture is realized in a concrete HORSE system and deployed and evaluated in ten practical cases, of which one is discussed in detail. It is shown that the developed system can flexibly orchestrate the manufacturing process through vertical control of all agents, and dynamic allocation of agents in the manufacturing process. Based on that, we conclude that BPM can be applied to overcome some of the obstacles toward increased flexibility and smart manufacturing.

"Patient characteristics associated with the decision to undergo bilateral prophylactic mastectomy for lobular carcinoma in situ." Journal of Clinical Oncology 29, n. 27_suppl (20 settembre 2011): 148. http://dx.doi.org/10.1200/jco.2011.29.27_suppl.148.
Abstract (sommario):
148 Background: Women at increased risk for breast cancer due to a diagnosis of lobular carcinoma in situ (LCIS) have three management options: high risk surveillance +/- chemoprevention (CP) or bilateral prophylactic mastectomy (BPM). Among a large cohort of women with LCIS, we previously reported there were no differences between women choosing CP compared to those choosing surveillance alone. The purpose of this study was to identify patient factors associated with the decision to pursue BPM for LCIS. Methods: We reviewed our prospectively maintained LCIS database to identify women choosing BPM (1995-2009). Comparisons were made between patients who chose BPM versus those who chose high risk surveillance +/- CP. Results: Among 995 pts with LCIS, 795 (80%) chose surveillance alone, 149 (15%) chose CP and 51 (5%) chose BPM. Compared to patients electing surveillance +/- CP patients who pursued BPM were younger at age of LCIS diagnosis (48 vs. 52 yrs, p < 0.001), more likely to have bilateral biopsies with LCIS (14% vs. 3%, p = 0.002) and more likely to be premenopausal (82% vs. 57%, p < 0.001). Patients choosing BPM were also more likely to have additional risk factors for breast cancer including: stronger family histories and extremely dense breasts (Table). Occult breast cancer was found in 4 (8%) BPM patients. At a median follow-up of 54 months (range 0-190 mos), 120/944 (13%) patients in the surveillance +/- CP group developed breast cancer. Conclusions: High-risk surveillance alone is the preferred management option for women with LCIS at our institution. Patients electing BPM are younger and more likely to have other associated risk factors for developing breast cancer. Further research to define how the increased risk imparted by LCIS is augmented by these factors may allow for better risk stratification and more informed discussions with patients.

"Contribution of frequency-augmented inward Ca2+ current to myocardial contractility". Canadian Journal of Physiology and Pharmacology 87, n. 1 (gennaio 2009): 69–75. http://dx.doi.org/10.1139/y08-087.
Abstract (sommario):
The sarcoplasmic reticular Ca2+ pump (SERCA) is thought to be the primary determinant of heart rate-dependent increases in myocardial contractile [Ca2+]i and force (force–frequency relationship (FFR)), an important mechanism to increase cardiac output. This report demonstrates a rate-dependent role for inward Ca2+ current (ICa) in the human and rat FFR. Human action potential plateau height increased linearly with contractility when heart rate increased in vivo, as measured by monophasic action potential catheter and echocardiography. Rat rate-dependent developed force and cytosolic [Ca2+]i transients were quantified in isolated left ventricular papillary muscles, and ICa and action potential duration in cardiomyocytes. ICa and SERCA measurements better reflected [Ca2+]i and force transients than SERCA activity alone. These data support a direct and (or) indirect contribution to myocardial contractility by ICa at heart rates from approximately 1 to 3–4 Hz (60 to 180–240 bpm) in tandem with SERCA to sustain the typical ‘bell shape’ of the FFR across species.

Abstract (sommario):
Abstract Background Preterm-born (PT) children have an increased risk for obstructive sleep apnoea (OSA) and adverse cardiovascular outcomes. Respiratory events elicit acute changes in heart rate (HR) in term-born (T) children. Whether this response is augmented in PT children with OSA remains unclear. We aimed to analyse the HR response during obstructive respiratory events in PT children with OSA. Methods Nine PT children (3–12 y), were matched for obstructive apnoea hypopnoea index (OAHI), age and gender with T children. Beat-to-beat HR was averaged 10s before, during and the peak after (post) each obstructive event, and peak HR was expressed as percentage change. Results 323 obstructive events in PT and 376 in T children were identified, consisting of 681 hypopnoeas (PT 320; T 361) and 18 apnoeas (PT 3; T 15). There were insufficient apnoeas in the PT group for analysis. For hypopnoeas during total sleep, the PT group had significantly lower HR compared to the T group before median 81bpm (IQR 74–87) vs 88 bpm (79–99); p<0.001), during (76 bpm (69–83) vs 82 bpm (74–92; p<0.001) and post (97 bpm (89–103) vs 105 bpm (95–115; p<0.001) events. The post event increase in HR was significantly higher in the PT (26%, (16–39)) compared with the T (23%, (14–36)) group, p=0.008. Conclusion Although HR was lower during obstructive hypopnoeas in preterm compared with term-born children, the post event surge was significantly higher. This heightened HR response to respiratory events in children born preterm may underlie the worse cardiovascular outcomes in these children.

Abstract (sommario):
<b><i>Objectives:</i></b> Study determined effects of arterial hypertension and impaired kidney function on acute cold exposure induced changes in peripheral and central aortic blood pressure (BP). <b><i>Methods:</i></b> Five-six subjects were divided into 3 groups including 20 hypertensive patients with normal kidney function (AH-non-CKD), 20 patients with hypertension and CKD (AH-CKD) stage 3b–4 and 16 healthy normotensive subjects (C). Baseline BP, central BP, and central pulse pressure, unadjusted augmentation index (AI) and central augmented pressure were assessed by applanation tonometry (SphygmoCor) before entering the room with constant temperature −10°C (°C), after 10 min in the cold room and in same conditions in room temperature. <b><i>Results:</i></b> Cold exposure led to significant increase of central aortic, systolic, and diastolic BP in both AH-non-CKD (<i>p</i> < 0.01) and AH-CKD (<i>p</i> < 0.001). The central aortic BP did not change in healthy subjects. The increase of central aortic systolic blood pressure was significantly larger in AH-CKD compared to AH-non-CKD group (<i>p</i> = 0.0002). Increase of aortic central and brachial systolic and diastolic BP was significantly larger in AH-CKD and AH-non-CKD patients than in controls. AI increased and subendocardial viability ratio and heart rate decreased after cold exposure in all groups. Central aortic and brachial rate pressure product increased by approximately 2,300 bpm × mm Hg (<i>p</i> < 0.001) and 1,600 bpm × mm Hg (<i>p</i> < 0.001), respectively, in the AH-CKD group and by 1,000 bpm × mm Hg (<i>p</i> = 0.007) and 500 bpm × mm Hg (<i>p</i> = 0.19) in AH-non-CKD group after cold exposure. <b><i>Conclusion:</i></b> Short-term cold exposure induces larger increase of brachial and central aortic BP in patients with arterial hypertension than in healthy subjects. The changes in central aortic pressure are augmented in hypertensive patients with impaired kidney function.

Abstract (sommario):
In the past decades, a number of methodologies have been proposed to innovate and improve business processes that play an important role in enhancing the operational efficiency of an organisation in order to attain business competitiveness. Traditional business process modelling (BPM) approaches are process-centric and focus on the workflow, ignoring the data modelling aspects that are essential for today’s data-centric landscape of modern businesses. Hence, a majority of BPM initiatives have failed in several organisations due to the lack of data-driven insights into their business performance. On the other hand, the information systems of today focus more on dataflows using object-oriented modelling (OOM) approaches. Even standard OOM approaches, such as unified modelling language (UML) methods, exhibit inherent weaknesses due to their lack of formalized innovation with business objects and the dynamic control-flows of complex business processes. In addition to these issues, both BPM and OOM approaches have been augmented with an array of complex software tools and techniques which have confused businesses. There is a lack of a common generalized framework that integrates the well-formalised control-flow based BPM approach and the dataflow based OOM approach that is suitable for today’s enterprise systems in order to support organisations to achieve successful business process improvements. This paper takes a modest step to fill this gap. We propose a framework using a structured six-step business process modelling (BPM) guideline combined with a business object-oriented methodology (BOOM) in a unique and practical way that could be adopted for improving an organisation’s process efficiency and business performance in contemporary enterprise systems. Our proposed business object-oriented process modelling (BOOPM) framework is applied to a business case study in order to demonstrate the practical implementation and process efficiency improvements that can be achieved in enterprise systems using such a structured and integrated approach.

Abstract (sommario):
P48 The onset of renal wrap hypertension is associated with a reduced tonic GABA inhibition in the paraventricular nucleus (PVN) on the sympathetic nervous system. This reduced functional inhibition occurs without a change in GABA-A receptor binding in the PVN. The goal of the present study was to determine if GABAergic transmission and GABA binding is altered in chronic renal wrap hypertensive rats. Sprague-Dawley rats were made hypertensive or sham-operated. Four weeks later, animals were prepared with femoral artery catheters for the measurement of arterial pressure. Subgroups were also prepared with bilateral cannulae directed at the PVN. The renal wrap rats had higher mean arterial pressure (MAP): 139±4 mmHg vs.113±2 mmHg, but heart rate (HR) was not different (354±12 bpm vs. 369±6 bpm) as compared to control animals. Administration of the GABA-A antagonist, bicuculline, into the PVN caused a greater increase in MAP and HR in wrap animals (25±2 mmHg and 150±30 bpm) compared to sham operated rats (16±2 mmHg and 89±12 bpm). GABA-A binding sites in the PVN were estimated using in vivo autoradiography. [3H]-Flunitrazepam was used as the receptor ligand. Magnocellular neurons of the PVN showed a higher density of receptors than other areas of the nucleus. However, the number of binding sites was not different between normotensive and hypertensive rats in either the high density (1825±56 vs. 1756±41 fmol/mg protein) or low density (1454±26 vs. 1433±57 fmol/mg protein) regions of PVN. These data indicate that the inhibition by GABA in the PVN is augmented in the chronic stage of hypertension, and appears to be unrelated to a change in the number of GABA binding sites. The increased GABAergic inhibition is in contrast to the reduced inhibition that has been observed during the onset of hypertension.

"Speckle-tracking strain echocardiography for detecting cardiac dyssynchrony in a canine model of dyssynchrony and heart failure". American Journal of Physiology-Heart and Circulatory Physiology 293, n. 1 (luglio 2007): H735—H742. http://dx.doi.org/10.1152/ajpheart.00168.2007.
Abstract (sommario):
Multiple echocardiographic criteria have been proposed to diagnose mechanical dyssynchrony in patients with heart failure without being validated against a model of cardiac dyssynchrony with heart failure. This study examines which of these methods can detect dyssynchrony in a canine model. Adult mongrel dogs underwent His-bundle ablation and right-ventricular pacing for 4 wk at either 110 bpm to induce dyssynchrony without heart failure (D group, n = 12) or 170 bpm to induce dyssynchrony with heart failure (DHF group, n = 9). To induce heart failure with narrow QRS, atria were paced at 190 bpm for 4 wk (HF group, n = 8). Tissue Doppler imaging (TDI) and two-dimensional echocardiography were performed at baseline and at end of study. Standard deviation of time to peak systolic velocity (color-coded TDI), time to peak S wave on pulse-wave TDI, time to peak radial and circumferential strain by speckle-tracking analysis ( Err and Ecc, respectively), and septal-to-posterior wall motion delay on M mode were obtained. In D group, only Err and Ecc were increased by dyssynchrony. In contrast, all the echocardiographic parameters of dyssynchrony appeared significantly augmented in the DHF group. Receiver-operator curve analysis showed good sensitivity of Err (90%) and Ecc (100%) to detected dyssynchrony without heart failure and excellent sensitivity and specificity of Err and Ecc to detect dyssynchrony with heart failure. Radial strain by speckle tracking is more accurate than TDI velocity to detect cardiac dyssynchrony in a canine model of dyssynchrony with or without heart failure.

Abstract (sommario):
The spin-crossover [Fe(bt)(NCS)2]2(bpm) complex is studied using spin-polarized density functional theory within the generalized gradient approximation, the Hubbard U and the weak van der Waals interactions in conjunction with the projector augmented wave method in its molecular and periodic arrangements. It is shown that the considered complex has three magnetic configurations [high spin state (HS)–HS, HS–low spin state (LS), and LS–LS] corresponding to those observed experimentally after two transition temperatures [Formula: see text] of 163 K and [Formula: see text] of 197 K. For the HS–HS magnetic state, we found that the two Fe centers are antiferromagnetically coupled for both molecular and periodic structures in good agreement with the experimental observations. Our results show that the computed total energy difference between the magnetic state configurations of the considered Fe2 complex is significantly smaller compared to those reported in the literature for other mono- or binuclear compounds.

Abstract (sommario):
Les processus métiers peuvent être vu comme une collection d'activités exécutées et coordonnées afin de produire un résultat bien spécifique, répondant aux besoins d'un client (interne et/ou externe). La gestion des processus métiers (Business process management - BPM) est un domaine de recherche très actif dans la discipline des systèmes d'informations. Il a pour objectif l'amélioration continue de l'efficacité et la performance des processus d'une entreprise, par le biais des méthodes, des techniques et des outils qu'il offre afin d'appuyer la conception, la mise en œuvre, la gestion, l'analyse, et l'automatisation, dans la mesure du possible, des processus métier, et donc gagner en termes d'agilité,de flexibilité et de performance. Même si plusieurs méthodes d'amélioration des processus métier (Business Process Improvement- BPI) sont disponibles dans la littérature, les organisations rencontrent toujours des difficultés pour les appliquer efficacement. Ces difficultés peuvent être justifiées par le fait que les méthodes BPI existantes ne répondent pas à toutes les exigences récentes des organisations et ne s'adaptent pas aux progrès réalisés, ces dernières années, dans plusieurs domaines tels que l'intelligence artificielle, les techniques d'analyse des données, l'apprentissage automatique, le process mining et le traitement des (flux) événements, etc. En outre, avec cette nouvelle ère de digitalisation et l'essor de plusieurs nouvelles technologies telles que le Big Data, l'Internet des objets (IoT), le Cloud Computing, etc, les organisations sont confrontées à de nouveaux facteurs et défis redéfinissant le marché et qui génèrent de réels changements dans le BPM traditionnel. Parmi ces nouveaux défis on trouve la quantité de données et d'événements, provenant, avec une très grande vélocité,de différentes sources hétérogènes (des interactions internes ou externes de l'entreprise,IoT, etc). Ces données doivent être bien analysées et exploitées afin d'en extraire, des résultats à forte valeur ajoutée qui peuvent aider l'entreprise dans son processus de prise de décision. Cependant, les outils traditionnels proposés par la méthode du management des processus métiers présentent différentes limites concernant le traitement, la fouille et l'analyse des données et l'exploitation des résultats de ces analyses en temps réel. La nature interdisciplinaire du BPM est un facteur clé qui favorise les perspectives d'amélioration dans ce domaine. L'objectif de ce travail de thèse est de proposer de nouvelles approches pour augmenter les processus métier, en s'appuyant principalement sur l'analyse des données, les algorithmes d'apprentissage automatique et le traitement des événements complexes, afin d'exploiter les données et événements générés par l'exécution des processus métier et de trouver des moyens d'améliorer ces processus sous différents angles tels que l'ordonnancement des instances et la gestion des événements dans un environnement IoT. L'loT est en train de devenir une zone d'innovations technologiques et de promesses de développement économique pour de nombreuses industries et services. Ce nouveau changement de paradigme affecte toutes les couches de l'architecture d'entreprise, de l'infrastructure au métier. Le Business Process Management (BPM) est un domaine parmi d'autres qui est affecté par cette nouvelle technologie. Pour faire face à l'explosion des données et des événements résultant, entre autres, de l'loT, les processus d'analyse de données combinés aux techniques de traitement des événements, examinent de grands ensembles de données pour découvrir des modèles cachés, des corrélations inconnues entre les événements collectés, soit à un niveau très technique (détection des incidents/anomalies, maintenance prédictive), soit au niveau métier (préférences des clients, tendances du marché, opportunités de revenus) pour fournir une meilleure efficacité opérationnelle, un meilleur service client et des avantages [...]Business Processes (BP) can be seen as a collection of activities executed and coordinated in order to produce a specific result and to meet the needs of a customer (internal and/or external). Business process management (BPM) is a very active research area, its objective is to provide a comprehensive and insightful analysis of the product flow and to identify inefficiencies and potential improvement areas in the process to achieve better decision making and results. Although we can find several Business Process Improvement (BPI) methods in the literature, organizations are still facing some difficulties to apply these methods effectively. These difficulties can be justified by the fact that the existing BPI methods do not fi twith all the recent requirements of the organizations and the progress that the world has achieved, in the past few years, in several domains such as Artificial Intelligence, Data Analytics techniques, Machine Learning, Process Mining, and Event (Stream) Processing, etc. Besides, with this new digitized era and the rise of several new technologies such as Big Data, Internet of things, Cloud computing, etc, organizations are faced with many factors and challenges that generate real changes in the traditional BPM. Among these challenges, we have the huge amount of data and event data that are continuously gathered within the organization. These data represent a real engine of growth for organizations, and must be adequately exploited to extract high added value that can assist the organization in its decision making process. Furthermore, enterprises are looking for advanced technologies that optimize time and resources and increase agility, productivity and most importantly, proactivity. However, traditional BPM systems present different limits, as they do not facilitate the use of knowledge extracted from this data, by business processes, because they do not benefit from statistical functionalities and data analysis and manipulation techniques in real time.The interdisciplinary nature of BPM is a key factor that fosters opportunities for improvement in this domain. The objective of this thesis work is to propose new approaches for augmenting business processes, by relying mainly on data analysis, machine learning algorithms, and complex event processing, to exploit the data generated by business process execution (event data, event logs) and find ways to improve these processes from different perspectives such as instances scheduling and event management in an IoT environment

Appelberg, Emelie, e Maria Bremberg. "Effektivisering av byggproduktion med VDC och förstärkt verklighet : Streamlining construction work with VDC and augmented reality". Thesis, KTH, Byggvetenskap, 2013. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-123797.
Abstract (sommario):
Virtual Design and Construction (VDC) is currently used more and more within construction design and planning as well as construction as a streamlining tool aiming to improve communication and decrease the number of construction defects. VDC is constantly developing, but what comes next? The augmented reality (AR) technology is currently not used within construction in Sweden but should be considered as the next step in line regarding the integration of reality and digital information. Using this technology design can become reality even before it’s actually built. The purpose of this study has been to carry out an inventory of the existing AR technology and its shortcomings, and also to identify possible applications within the construction phase. VDC has also been investigated in order to identify the weaknesses in this technology and an assessment has been made as to how these can be eliminated and hence how VDC can be improved. Based on that this thesis has been carried out with the following main question: How can augmented reality be implemented in the construction industry and how can it become integrated with VDC in order to achieve a streamlining effect in construction? The theoretical background is based on a literature study where information about augmented reality has been collected from technical reports from all over the world. A study of the technology behind augmented reality and its possible areas of application as well as a description of the future possibilities and ongoing research has been made. VDC has only briefly been examined in the literature study. Interviews with construction staff and experts within AR and VDC have been conducted in order to obtain a basis for an analysis of the current situation. Based on these interviews gains and shortcomings of the VDC technology have been identified, and requests for the AR technology’s future applications have been plotted. The result of the literature study is that a positioning technique that is more accurate and more robust than the ones on the market today needs to be developed in order for the AR-technology to work properly. There are a number of beneficial areas of application for AR in construction given that the previously mentioned problem is overcome. VDC in construction brings substantial benefits in terms of financial and time savings. It serves the communication between design and construction. AR will be easier to use for marketing purposes and early stages of projects than in construction. As for VDC more focus needs to be put on the implementation of the technology to a broader crowd rather than developing the technology further in a small group of experts. In order for augmented reality to be implemented in the construction industry VDC and its support need to be further developed towards construction before yet another technology is introduced. Augmented reality will not solve the shortcomings of VDC today.I dagsläget används Virtual Design and Construction (VDC) mer och mer inom byggprojektering såväl som inom byggproduktion som ett effektiviserande arbetssätt för att förbättra kommunikation och minska byggnadsfel. VDC är under ständig utveckling, men vad kommer efter denna? Förstärkt verklighet (AR, eng. Augmented Reality) används i dagsläget inte i byggproduktion i Sverige men ses som nästa steg i ledet av integrering av verklighet och digital information. Med hjälp av denna teknik kan projektering bli verklighet innan det är byggt. Syftet med denna studie har varit att inventera existerande AR-teknik, dess brister samt att kartlägga möjliga användningsområden inom byggproduktion. VDC har även undersökts för att identifiera denna tekniks svagheter och en bedömning av hur dessa kan avhjälpas och VDC förbättras har gjorts. Utifrån detta har arbetet utförts utifrån följande huvudfrågeställning; Hur kan AR-teknik implementeras i byggbranschen och hur kan den integreras med VDC för att uppnå en effektivisering i byggproduktionen? Teoribakgrunden bygger på en litteraturstudie där information om AR-teknik från tekniska rapporter inhämtats. En studie av tekniken bakom Augmented Reality och dess möjliga tillämpningsområden inom byggproduktion har gjorts, samtidigt som framtida möjligheter och pågående forskning har beskrivits. VDC har endast undersökts flyktigt i litteraturstudien. Intervjuer har genomförts med produktionspersonal och sakkunniga inom VDC och AR för att erhålla underlag för en nulägesanalys. Utifrån intervjuerna har nytta och brister med VDC-tekniken kunnat utrönas, samtidigt som önskemål på AR-teknikens framtida tillämpning har kunnat kartläggas. Resultatet av litteraturstudien är att en positioneringsteknik som är noggrannare och mer robust än de som finns idag måste utvecklas för att AR-tekniken ska fungera i syftet. Det finns ett flertal fördelaktiga tillämpningsområden för AR i byggproduktion förutsatt att ovanstående problem övervinns. VDC i produktion innebär stora fördelar i form av ekonomiska och tidsmässiga besparingar. Det främjar kommunikationen mellan projektering och produktion. AR kommer att vara lättare att använda i marknadsföringssyfte och i tidiga skeden än i produktion. Vad gäller VDC behöver mer fokus läggas på att implementera tekniken till den stora massan istället för att utveckla tekniken ytterligare i en liten expertgrupp. För att AR-tekniken ska kunna implementeras i byggbranschen bör VDC-tekniken och dess stöd först utvecklas fullt ut mot produktion innan ytterligare en teknik introduceras då denna inte kommer att åtgärda de brister med VDC som finns idag.

Landrieu, Jeremie. "Apport des réalités virtuelles et augmentées dans la planification et le suivi in situ de travaux de rénovation". Phd thesis, Paris, ENSAM, 2013. http://pastel.archives-ouvertes.fr/pastel-00936702.
Abstract (sommario):
Ce mémoire de thèse de doctorat présente l'évaluation d'un système de réalité mixte dans le cadre d'une utilisation sur le site d'opération de construction. Il s'agit notamment de déterminer la pertinence d'un tel outil mobile pour des opérateurs pour les assister dans leurs tâches quotidiennes, et notamment dans la préparation et le suivi des opérations de construction ou rénovation. Cet outil se voudrait être un outil d'aide à la décision pour les maîtres d'ouvrages et maîtres d'œuvre. Le cas d'étude porte sur la rénovation virtuelle des baies anciennes (datées du XVIIIème siècle) dans une cellule des bâtiments conventuels de Cluny (Saône et Loire, France). L'approche consiste à comparer l'efficacité, la précision et la rapidité d'opérateurs dans la réalisation de tâches identiques. Trois méthodes liées à l'utilisation des nouvelles technologies dans le domaine de l'AIC (Architecture Ingénierie et Construction) sont comparées, elles ont guidé la définition du protocole expérimental. La première méthode traditionnelle fournit à l'opérateur de la documentation papier. La seconde met en œuvre la dématérialisation des données constructives, accessibles depuis un ordinateur de bureau. La troisième méthode plus innovante ajoute à la précédente l'accès colocalisé à la base de données grâce à un terminal mobile. Une étude qui a suivi a porté sur la visualisation et l'interprétation de résultats de simulation thermique, en réalité virtuelle. La comparaison des trois premières méthodes a donné lieu à une première expérimentation dont les résultats ont montré la légère prédominance du second scénario (travail sur ordinateur de bureau). Cependant, au-delà des aspects d'ergonomie et d'interface utilisateur, des investigations complémentaires doivent être menées pour étudier l'opportunité du développement du BIM in situ, c'est-à-dire l'utilisation du modèle de données du bâtiment (BIM- Building Information Model) sur le chantier.

Abstract (sommario):
Molnlagring, kommunikationsplattformar med interaktiva funktioner, virtuella modeller som sammanfogas med fysiska omgivningar, datorsimuleringar, livscykelperspektiv. Så diskuteras det i BIM-världens korridorer. Men om detta nu är framtiden: varför går implementeringen så långsamt, och vad är det egentligen som ska implementeras? Processen att hantera och förstå vad BIM är har blivit för komplex, och med denna rapport vill vi hitta åtgärder för att göra arbetssättet begripligt och användbart för fler. Vi har i samarbete med Vianova Systems undersökt hur användningen av BIM ser ut idag och vilka förbättringsåtgärder som behövs för en bredare framtida implementering i samhällsbyggnadsbranschen. Våra undersökningar visar att nästan 80 % tror att ett arbete som drar nytta av en digital modell skulle vara effektivare: samtidigt är osäkerheten kring mjukvaror och oklarhet kring implementeringen av arbetsmetoderna begränsande faktorer. Som lösning på detta har ett användarinterface för projektsamordning och kommunikation arbetats fram. Dessa undersökningar har genomförts med hjälp av en enkätstudie samt intervjuer och sammanställts i två delar: dels denna rapport, samt en slutprodukt av visionär karaktär kallad ”7 visions for the future of BIM”.Cloud storage, communication platforms with interactive functions, virtual models that are merged with physical surroundings, computer simulations, life cycle perspective. This is what is being discussed in the corridors of the BIM-world. But if this is the future: why is the implementation so slow, and what exactly is to be implemented? The process of handling and understanding what BIM is has become too complex, and in this report we want to find solutions for making the way of working intelligible and useful for a wider audience. In collaboration with Vianova Systems, we have investigated what the use of BIM looks like today and what improvements are needed for a wider future implementation in the AEC industry. Our investigations show that almost 80 % believe that work which utilizes a digital model would be more effective: at the same time the insecurity concerning software and uncertainties regarding the implementation of the work methodologies are limiting factors. As a solution for this a user interface for project management and communication has been developed. These investigations have been carried out with the aid of a questionnaire and interviews and compiled into two parts: partly this report, as well as an end product of visionairy nature called ”7 visions for the future of BIM”.

Kopsida, Marianna. "Automated progress monitoring using mixed reality". Thesis, University of Cambridge, 2018. https://www.repository.cam.ac.uk/handle/1810/274926.
Abstract (sommario):
This thesis presents a real-time automated building progress monitoring solution for indoor environments using a mobile device. Such a system could prompt accurate and timely assessment of work progress that would allow managers to make adjustments and minimise both time and cost overrun when deviations from the schedule occur. Although many researchers have proposed approaches for progress monitoring in outdoor scenes, these cannot perform in real-time and shift into the complex interior environment. Research efforts for indoor environments are not fully automated and lead to errors in more complex scenes. Systems based on mobile devices could potentially enhance the inspection process and reduce the required time by allowing the inspector to acquire progress data by simply walking around the site. The main challenge of these systems is the tracking of the pose of the camera to achieve accurate alignment between the 3D design model and the real-world scene. Methods for estimating the user’s pose rely on a) tags on each target of interest, which require additional time and cost for installation and maintenance; b) pre-selected user locations, which restricts the user to those locations only; or c) GPS on the augmented reality headset, which only applies to outdoor inspections. Additionally, current mobile-based inspection systems do not perform any comparison between the captured as-built and the as-planned data. In this research, different marker-less Augmented Reality (AR) potential methods were implemented and tested for finding the most robust tracking solution. The Microsoft HoloLens was found to be the top performer for tracking the user’s pose and for overall user-experience. Next, a semi-automated method was developed for initially registering the 3D model to the real environment by exploiting information from detected floor and wall surfaces. Results showed that this method reduces the time of the initial registration by 58%. Having the 3D model aligned to the real environment and knowing the pose of the camera at every moment, an automated method was developed that exploits the captured as-built surface mesh data from the mobile device, compares it against the 3D design model and identifies in real-time whether an object has been built according to plan. Different parameters were tested for finding the optimum combination based on the current quality of mesh data. If quality of mesh data changes, then new parameters should be explored. Finally, the proposed solution was tested in real site conditions resulting in 76.6% precision, 100.0% recall, and 83.5% accuracy.

Abstract (sommario):
This project examined the role that written specifications play in the building procurement process and the relationship that specifications should have with respect to the use of BIM within the construction industry. A three-part approach was developed to integrate specifications, product libraries and BIM. Typically handled by different disciplines within project teams, these provide the basis for a holistic approach to the development of building descriptions through the design process and into construction.

Abstract (sommario):
The creation of an effective construction schedule is fundamental to the successful completion of a construction project. Effectively communicating the temporal and spatial details of this schedule are vital, however current planning approaches often lead to multiple or misinterpretations of the schedule throughout the planning team. Four Dimensional Computer Aided Design (4D CAD) has emerged over the last twenty years as an effective tool during construction project planning. In recent years Building Information Modelling (BIM) has emerged as a valuable approach to construction informatics throughout the whole lifecycle of a building. Additionally, emerging trends in location-aware and wearable computing provide a future potential for untethered, contextual visualisation and data delivery away from the office. The purpose of this study was to develop a novel computer-based approach, to facilitate on-site 4D construction planning through interaction with a 3D construction model and corresponding building information data in outdoor Augmented Reality (AR). Based on a wide ranging literature review, a conceptual framework was put forward to represent software development requirements to support the sequencing of construction tasks in AR. Based on this framework, an approach was developed that represented the main processes required to plan a construction sequence using an onsite model based 4D methodology. Using this proposed approach, a prototype software tool was developed, 4DAR. The implemented tool facilitated the mapping of elements within an interactive 3D model with corresponding BIM data objects to provide an interface for two way communication with the underlying Industry Foundation Class (IFC) data model. Positioning data from RTK-GPS and an electronic compass enabled the geo-located 3D model to be registered in world coordinates and visualised using a head mounted display fitted with a ii forward facing video camera. The scheduling of construction tasks was achieved using a novel interactive technique that negated the need for a previous construction schedule to be input into the system. The resulting 4D simulation can be viewed at any time during the scheduling process, facilitating an iterative approach to project planning to be adopted. Furthermore, employing the IFC file as a central read/write repository for schedule data reduces the amount of disparate documentation and centralises the storage of schedule information, while improving communication and facilitating collaborative working practices within a project planning team. Post graduate students and construction professionals evaluated the implemented prototype tool to test its usefulness for construction planning requirements. It emerged from the evaluation sessions that the implemented tool had achieved the essential requirements highlighted in the conceptual framework and proposed approach. Furthermore, the evaluators expressed that the implemented software and proposed novel approach to construction planning had potential to assist with the planning process for both experienced and inexperienced construction planners. The following contributions to knowledge have been made by this study in the areas of 4D CAD, construction applications of augmented reality and Building Information Modelling; · 4D Construction Planning in Outdoor Augmented Reality (AR) · The development of a novel 4D planning approach through decomposition · The deployment of Industry Foundation Classes (IFC) in AR · Leveraging IFC files for centralised data management within real time planning and visualisation environment.

Abstract (sommario):
In the last years smart buildings topic has received much attention as well as Building Information Modelling (BIM) and interoperability as independent fields.
Linking these topics is an essential research target to help designers and stakeholders to run processes more efficiently. Working on a smart building requires the use of Innovation and Communication Technology (ICT) to optimize design, construction and management. In these terms, several technologies such as sensors for remote monitoring and control, building equipment, management software, etc. are available in the market.
As BIM provides an enormous amount of information in its database and theoretically it is able to work with all kind of data sources using interoperability, it is essential to define standards for both data contents and format exchange. In this way, a possibility to align research activity with Horizon 2020 is the investigation of energy saving using ICT. Unfortunately, comparing the Architecture Engineering and Construction (AEC) Industry with other sectors it is clear how in the building field advanced information technology applications have not been adopted yet. However in the last years, the adoption of new methods for the data management has been investigated by many researchers.
So, basing on the above considerations, the main purpose of this thesis is investigate the use of BIM methodology relating to existing buildings concerning on three main topics:
• Smart data management for architectural heritage preservation;
• District data management for energy reduction;
• The maintenance of highrises.
For these reasons, data management acquires a very important value relating to the optimization of the building process and it is considered the most important goal for this research. Taking into account different kinds of architectural heritage, the attention is focused on the existing and historical buildings that usually have characterized by several constraints.
Starting from data collection, a BIM model was developed and customized in function of its objectives, and providing information for different simulation tests. Finally, data visualization was investigated through the Virtual Reality(VR) and Augmented Reality (AR). Certainly, the creation of a 3D parametric model implies that data is organized according to the use of individual users that are involved in the building process. This means that each 3D model can be developed with different Levels of Detail/Development (LODs) basing on the goal of the data source.
Along this thesis the importance of LODs is taken into account related to the kind of information filled in a BIM model. In fact, basing on the objectives of each project a BIM model can be developed in a different way to facilitate the querying data for the simulations tests.
The three topics were compared considering each step of the building process workflow, highlighting the main differences, evaluating the strengths and weaknesses of BIM methodology. In these terms, the importance to set a BIM template before the modelling step was pointed out, because it provides the possibility to manage information in order to be collected and extracted for different purposes and by specific users. Moreover, basing on the results obtained in terms of the 3D parametric model and in terms of process, a proper BIM maturity level was determined for each topic.
Finally, the value of interoperability was arisen from these tests considering that it provided the opportunity to develop a framework for collaboration, involving all parties of the building industry.

Abstract (sommario):
Nowadays BIM and real-time data are becoming a central topic for the AECO (Architecture, Engineering, Construction and Operations) industry, they represent new powerful tools for the design and management of facilities.Building monitoring and real-time data can represent a solution to many important challenges like energy efficiency, indoor climate quality and cost management. Although it is clear the importance of data for a correct use of BIM technology and its potentiality, in literature, are not so common examples of complete workflows for a complete management of data from the input phase to the output one.The scope of the study is to design a protocol for entering, managing and exporting real-time data using Revit and Dynamo where the customers have a central role during the input phase and a dedicated mode for data display including a desktop version and an augmented reality one for a more immersive experience.In order to show the real potentiality of the project, the protocol has been utilised for the calculation of thermal comfort parameters of the “Teaching House” situated in KTH campus. All data entered from the students into a form online, via QR-code, have been inserted into Dynamo in order to calculate the desired parameters values which are successively stored into a database for further analysis, everything automatically.Numera blir BIM och realtidsdata ett centralt ämne för AECO (Architecture, Engineering, Construction and Operations) industrin, de representerar nya kraftfulla verktyg för design och hantering av anläggningar.Byggnadsövervakning och realtidsdata kan vara en lösning på många viktiga utmaningar som energieffektivitet, inomhusklimatkvalitet och kostnadshantering. Även om det är tydligt är betydelsen av data för en korrekt användning av BIM-teknik och dess potential i litteraturen inte så vanliga exempel på fullständiga arbetsflöden för en fullständig hantering av data från inmatningsfasen till den utgående.Studiens omfattning är att utforma ett protokoll för inmatning, hantering och export av realtidsdata med Revit och Dynamo där kunderna har en central roll under inmatningsfasen och ett dedikerat läge för datavisning inklusive en stationär version och en förstärkt verklighet en för en mer uppslukande upplevelse.För att visa projektets verkliga potential har protokollet använts för beräkning av termiska komfortparametrar för ”Teaching House” beläget på KTH campus. Alla data som matats in från eleverna i ett formulär online, via QR-kod, har införts i Dynamo för att beräkna önskade parametervärden som successivt lagras i en databas för vidare analys, allt automatiskt.

Abstract (sommario):
Augmented reality (AR) systems offer new possibilities for enhancing how people interact with information and their environment in the construction sector. However, traditional software-driven approaches to AR system design have limitations in creating intuitive user experiences. This research presents a new user-centric framework and ontology for BIM-AR system development focused on human needs and perspectives. The BIM-AR Framework consists of a 5-step circular hybrid process with the user at the center. To enable knowledge sharing, the Augmented Reality Computer-Human Interaction (ARCHI) ontology was developed using Protégé based on established design principles. Initial validation indicates the framework's potential for improved AR system design, but further expert review and case studies are needed. The ontology also requires additional refinement and linkage to open data. This pioneering research lays the groundwork for next-generation AR systems that emphasize usability by taking a human-focused approach. With rigorous validation and evolution, the framework and ontology could transform AR technology development to create more purpose-driven and adopted solutions. This research represents a paradigm shift to user-centric AR system design that has significant potential to improve how augmented reality enhances construction project management

Abstract (sommario):
Technologies guiding building production introduce architectural techniques of vision. Beyond changes in the management of design and construction, BIM, integrated with new hardware such as augmented reality devices, produces new forms of perception and visualization. These shifts in the social-visual order of architectural production are abundant. They can be seen in promotional videos for augmented reality headsets as well as architectural schools and offices. An analysis of images and videos made with augmented reality hardware (integrated with BIM) suggests ways that architects can relate emerging construction technologies to aesthetic and disciplinary forms of knowledge, connecting historical conceptions of representation and abstraction to emerging modes of practice.

Abstract (sommario):
The aim of this research is to generate a resource to assist construction lecturers in identifying opportunities where Building Information Modelling [BIM] could be employed to augment the delivery of subject content within individual courses on construction technology programmes. The methodology involved a detailed analysis of the learning objectives and underpinning knowledge of the course content by topic area, within the residential Construction Systems 1 course presently delivered at Unitec on the National Diplomas in Architectural Technology[NDAT], Construction Management [NDCM] and Quantity Surveying [NDQS]. The objective is to aid students’ understanding of specific aspects such as planning controls or sub-floor framing by using BIM models, and investigate how these could enhance delivery modes using image,animation and interactive student activity. A framework maps the BIM teaching opportunities against each topic area highlighting where these could be embedded into construction course delivery. This template also records software options and could be used in similar analyses of other courses within similar programmes to assist with embedding BIM in subject delivery.

Management of Postpartum Hypertensive Disorders of Pregnancy. Agency for Healthcare Research and Quality (AHRQ), maggio 2023. http://dx.doi.org/10.23970/ahrqepccer263.
Abstract (sommario):
Background. Hypertensive disorders of pregnancy (HDP) are increasingly common and have important implications for maternal health, healthcare utilization, and health disparities. There is limited evidence to support best management of postpartum individuals with HDP, including home blood pressure (BP) monitoring (HBPM) and choice of antihypertensive agents. For patients experiencing preeclampsia with severe features, there is robust evidence supporting delivery of the infant and treatment with magnesium sulfate (MgSO4). However, MgSO4 may cause unpleasant side effects and, less commonly, toxicity. Patients receiving MgSO4 require additional monitoring (e.g., urinary catheterization) and often have activity restrictions, which impact their postpartum experience. Evidence regarding the optimal (lowest effective) dose and (shortest effective) duration of MgSO4 treatment is needed. Methods. We searched Medline®, Cochrane, Embase®, CINAHL®, and ClinicalTrials.gov from inception to December 1, 2022. After double screening, we extracted study data and risk of bias assessments into the Systematic Review Data Repository Plus (SRDR+; https://srdrplus.ahrq.gov). We evaluated the strength of evidence (SoE) using standard methods. The protocol was registered in PROSPERO (registration number CRD42022313075). Results. We found 13 eligible studies (3 randomized controlled trials [RCTs], 2 nonrandomized comparative studies [NRCSs], 8 single-arm studies) evaluating postpartum HBPM, 17 RCTs evaluating pharmacological treatment of postpartum HDP, and 43 studies (41 RCTs and 2 NRCSs) that compared alternative MgSO4 regimens. HBPM programs probably increase submission of any BP measurements during recommended time intervals (moderate SoE) and may increase the number of BP measurements obtained overall (low SoE). Studies have not found that HBPM affects the rate of BP treatment initiation (low SoE), but HBPM may reduce unplanned hypertension-related hospital admissions (low SoE). Most patients were satisfied with management related to HBPM (low SoE), and HBPM probably compensates for racial disparities in office-based follow-up (moderate SoE). In patients with preeclampsia or gestational hypertension (HTN), oral furosemide may shorten the duration of postpartum hypertension (low SoE). There was insufficient evidence regarding the comparative benefits and harms of other antihypertensive medications. Compared with 24-hour treatments, shorter duration MgSO4 regimens shorten the urinary catheterization time (high SoE), time to ambulation (high SoE), and time to breastfeeding (moderate SoE); and may shorten time from delivery to contact with the infant and decrease toxicity as manifested by lost deep tendon reflexes (both low SoE). Loading dose only regimens increase the risk of a recurrent seizure in patients with eclampsia (moderate SoE). Lower dose MgSO4 regimens, compared to standard dose regimens, reduce early signs of magnesium toxicity (high SoE), may approximately double the risk of recurrent seizure in patients with eclampsia (low SoE), but may not affect 5-minute Apgar scores in infants of patients with preeclampsia with severe features (low SoE). There is insufficient evidence regarding potential harms of concomitant use of nifedipine or other antihypertensive medications. Conclusion. HBPM probably improves ascertainment of BP, allowing early recognition of hypertension in postpartum patients, and probably compensates for racial disparities in office based follow-up. The evidence suggests furosemide may shorten the duration of postpartum HTN. However, further evidence is needed regarding the comparative benefits and harms of the antihypertensive medications used to treat postpartum HTN. Large pragmatic trials, augmented by analysis of real-world data, are needed to evaluate the effect of postpartum HBPM on clinical event outcomes (not only process outcomes) and on the comparative effectiveness of alternative antihypertensive treatments. Given that lower dose MgSO4 regimens reduce Mg toxicity, and shorter regimens decrease urinary catheterization time, time to ambulation, time to breastfeeding, and time from delivery to contact with the infant, evidence is needed to identify MgSO4 regimens with the lowest effective dose and shortest effective duration that minimize side effects and toxicity but still prevent seizures among patients with preeclampsia with severe features.

Abstract (sommario):
Both the genes and cDNA sequences encoding the b-subunits of black carp LH and FSH were isolated, cloned and sequenced. Sequence analysis of the bcFSHb and LHb5'flanking regions revealed that the promoter region of both genes contains canonical TATA sequences, 30 bp and 17 bp upstream of the transcription start site of FSHb and LHb genes, respectively. In addition, they include several sequences of cis-acting motifs, required for inducible and tissue-specific transcriptional regulation: the gonadotropin-specific element (GSE), GnRH responsive element (GRE), half sites of estrogen and androgen response elements, cAMP response element, and AP1. Several methods have been employed by the Israeli team to purify the recombinant b subunits (EtOH precipitation, gel filtration and lentil lectin). While the final objective to produce pure recombinantGtH subunits has not yet been achieved, we have covered much ground towards this goal. The black carp ovary showed a gradual increase in both mass and oocyte diameter. First postvitellogenic oocytes were found in 5 yr old fish. At this age, the testes already contained spermatozoa. The circulating LH levels increased from 0.5 ng/ml in 4 yr old fish to >5ng/ml in 5 yr old fish. In vivo challenge experiments in black carp showed the initial LH response of the pituitary to GnRH in 4 yr old fish. The response was further augmented in 5 yr old fish. The increase in estradiol level in response to gonadotropic stimulation was first noted in 4 yr old fish but this response was much stronger in the following year. In vivo experiments on the FSHb and LHb mRNA levels in response to GnRH were carried out on common carp as a model for synchronom spawning cyprinids. These experiments showed the prevalence of FSHP in maturing fish while LHP mRNA was prevalent in mature fish, especially in females. The gonadal fat-pad was found to originate from the retroperitoneal mesoderm and not from the genital ridge, thus differing from that reported in certain amphibians This tissue possibly serves as the major source of sex steroids in the immature black carp. However, such a function is taken over by the developing gonads in 4 yr old fish. In the striped bass, we described the ontogeny of the neuro-endocrine parameters along the brain-pituitary-gonadal axis during the first four years of life, throughout gonadal development and the onset of puberty. We also described the responsiveness of the reproductive axis to long-term hormonal manipulations at various stages of gonadal development. Most males reached complete sexual maturity during the first year of life. Puberty was initiated during the third year of life in most females, but this first reproductive cycle did not lead to the acquisition of full sexual maturity. This finding indicates that more than one reproductive cycle may be required before adulthood is reached. Out of the three native GnRHs present in striped bass, only sbGnRH and cGnRH II increased concomitantly with the progress of gonadal development and the onset of puberty. This finding, together with data on GtH synthesis and release, suggests that while sbGnRH and cGnRH II may be involved in the regulation of puberty in striped bass, these neuropeptides are not limiting factors to the onset of puberty. Plasma LH levels remained low in all fish, suggesting that LH plays only a minor role in early gonadal development. This hypothesis was further supported by the finding that experimentally elevated plasma LH levels did not result in the induction of complete ovarian and testicular development. The acquisition of complete puberty in 4 yr old females was associated with a rise in the mRNA levels of all GtH subunit genes, including a 218-fold increase in the mRNA levels of bFSH. mRNA levels of the a and PLH subunits increased only 11- and 8-fold, respectively. Although data on plasma FSH levels are unavailable, the dramatic increase in bFSH mRNA suggests a pivotal role for this hormone in regulating the onset and completion of puberty in striped bass. The hormonal regulation of the onset of puberty and of GtH synthesis and release was studied by chronic administration of testosterone (T) and/or an analog of gonadotropin-releasing hormone (G). Sustained administration of T+G increased the mRNA levels of the PLH subunit to the values characteristic of sexually mature fish, and also increased the plasma levels of LH. However, these changes did not result in the acceleration of sexual maturation. The mRNA levels of the bFSH subunit were slightly stimulated, but remained about 1/10 of the values characteristic of sexually mature fish. It is concluded that the stimulation of FSH gene expression and release does not lead to the acceleration of sexual maturity, and that the failure to sufficiently stimulate the bFSH subunit gene expression may underlie the inability of the treatments to advance sexual maturity. Consequently, FSH is suggested to be the key hormone to the initiation and completion of puberty in striped bass. Future efforts to induce precocious puberty in striped bass should focus on understanding the regulation of FSH synthesis and release and on developing technologies to induce these processes. Definite formulation of hormonal manipulation to advance puberty in the striped bass and the black carp seems to be premature at this stage. However, the project has already yielded a great number of experimental tools of DNA technology, slow-release systems and endocrine information on the process of puberty. These systems and certain protocols have been already utilized successfully to advance maturation in other fish (e.g. grey mullet) and will form a base for further study on fish puberty.
