Ornementation et discours architectural de la "villa" gallo-romaine d'Orbe-Boscéaz : l'apport des peintures

La présente thèse s'inscrit dans la continuité de la publication des fouilles menées de 1986 à 2002 sur le site de la villa gallo-romaine d'Orbe-Boscéaz/VD par l'Institut d'archéologie et des sciences de l'antiquité de l'Université de Lausanne (URBA I, à paraître dans les Cahiers d'archéologie romande). Elle constitue l'analyse approfondie du corpus des peintures murales fragmentaires -succinctement présentées dans URBA I - appartenant à la pars urbana qui succéda, entre 161 et 180 apr. J.-C, à un édifice plus petit du Ier s. de notre ère -dont les peintures sont publiées dans l'ouvrage sus-mentionné. N'ayant subi que de très rares modifications, cette pars urbana de caractère palatial forme un "ensemble clos" autorisant une analyse globale de la conception architecturale et décorative voulue par le bâtisseur ou son commanditaire. Le corpus pictural, composé d'un matériel assez ingrat remplissant quelque 600 cagettes de stockage, offre de ce fait l'intérêt d'une grande homogénéité chronologique et reflète la cohérence et l'unité de la décoration peinte d'origine. Le travail de discrimination et de remontage des ensembles a permet d'individualiser au moins 220 décors et revêtements muraux; l'ensemble des hypothèses de restitution des peintures donne ainsi une image minimale de l'environnement pictural de la pars urbana. Ce corpus pictural n'est toutefois que l'une des composantes du programme décoratif, aussi l'analyse de ses caractéristiques est-elle confrontée à celle des autres composantes ornementales (architecture, placages de marbres et surtout le remarquable ensemble des mosaïques qui fait la célébrité du site). La conjugaison des divers éléments et leur répartition au sein d'un plan bien connu et très symétrique orientent sur les choix décoratifs majeurs, et permettent sinon de reconstituer, tout au moins d'approcher la conception du programme architectural et décoratif voulu par le commanditaire ou son architecte; ce programme, comme fréquemment, reflète le statut du commanditaire, le met évidemment en scène et tient un discours sur la villa, adressé tant aux habitants qu'aux visiteurs. On trouvera dans le travail six chapitres formant l'essentiel de l'exploitation du corpus pictural urbigène. Le premier chapitre est introductif, et présente dans ses grandes lignes la pars urbana de Boscéaz comme cadre de référence. Il est suivi par un état des lieux des peintures murales retrouvées sur le site, abordant leur répartition, leur état de conservation et la méthodologie adoptée pour leur traitement comme leur étude (chapitre 2). Le chapitre 3 constitue l'étude technique des enduits peints. Il réunit toutes les observations que l'on peut faire sur les techniques de réalisation des peinture murales, de la préparation et la pose des mortiers de support aux tours de main des peintres pour le rendu d'un motif. Ce chapitre s'inscrit dans la perspective, appliquée à Boscéaz, d'études marquantes comme celles sur les techniques de préparation des parois (Allag /Barbet 1972, Barbet 1995) sur l'identification des pigments (PACT 17, 1985, Béarat 1997, Colloque de Fribourg 1997) et sur l'analyse des mortiers (Coutelas 2003). Suit le catalogue des peintures, basé sur une sélection de 3414 plaques remontées et fragments (chapitre 4) : il propose une description rigoureuse et systématique des motifs, ainsi que leur analyse stylistique qui apporte les éléments comparatifs permettant la compréhension du matériel, et justifiant son interprétation, voire sa restitution. Les décors y sont présentés par local de découverte; un paragraphe introductif réunit les données de fouille et des informations sur le local ou le prélèvement des enduits, et donne le nombre et la détermination des décors retrouvés. Chacun d'eux fait l'objet d'une notice regroupant: une détermination par le mortier de support (le tectorium); les observations techniques diverses; la description, la restitution le cas échéant, et l'analyse stylistique. Cette dernière privilégie les comparaisons locales, en Suisse d'abord puis dans les pays limitrophes de façon à mettre en évidence les liens plausibles entre certains sites et les éventuels indices d'une production régionale. La documentation graphique qui accompagne chaque décor dans le volume d'illustrations est constituée avant tout des planches photographiques des fragments à l'échelle 1:3, accompagnés le cas échéant de dessins au trait justifiant la lecture des motifs. Ceux-ci permettent la reconstitution idéale

Removal of unusual, large high-velocity metallic maxillary sinus foreign bodies by a modified free bone flap technique.

Metallic foreign bodies are rarely found in the maxillary sinus, and usually they have a dental origin.Potential complications related to foreign bodies include recurrent sinusitis, rhinolith formation, cutaneous fistula,chemical poisoning, facial neuralgic pain and even malignancies.Two main surgical approaches are currently used for the removal of foreign bodies in the maxillary sinus: the bone flap and the endoscopic sinus techniques. We are reporting two unusual cases of large high-velocity foreign bodies removed by a modified maxillary lateral antrotomy,with free bone flap repositioning and fixation with a titanium miniplate.

Prediction of plant species distributions across six millennia.

The usefulness of species distribution models (SDMs) in predicting impacts of climate change on biodiversity is difficult to assess because changes in species ranges may take decades or centuries to occur. One alternative way to evaluate the predictive ability of SDMs across time is to compare their predictions with data on past species distributions. We use data on plant distributions, fossil pollen and current and mid-Holocene climate to test the ability of SDMs to predict past climate-change impacts. We find that species showing little change in the estimated position of their realized niche, with resulting good model performance, tend to be dominant competitors for light. Different mechanisms appear to be responsible for among-species differences in model performance. Confidence in predictions of the impacts of climate change could be improved by selecting species with characteristics that suggest little change is expected in the relationships between species occurrence and climate patterns.

Via-configurable transistor array: a regular design technique to improve ICs yield

Process variations are a major bottleneck for digital CMOS integrated circuits manufacturability and yield. That iswhy regular techniques with different degrees of regularity are emerging as possible solutions. Our proposal is a new regular layout design technique called Via-Configurable Transistors Array (VCTA) that pushes to the limit circuit layout regularity for devices and interconnects in order to maximize regularity benefits. VCTA is predicted to perform worse than the Standard Cell approach designs for a certain technology node but it will allow the use of a future technology on an earlier time. Ourobjective is to optimize VCTA for it to be comparable to the Standard Cell design in an older technology. Simulations for the first unoptimized version of our VCTA of delay and energy consumption for a Full Adder circuit in the 90 nm technology node are presented and also the extrapolation for Carry-RippleAdders from 4 bits to 64 bits.

Performance Evaluation of Six-Sectored Configuration in Hexagonal WCDMA (UMTS) Cellular Network Layout

The objective of this master's thesis is to evaluate the optimum performance of sixsectored hexagonal layout of WCDMA (UMTS) network and analyze the performance at the optimum point. The maximum coverage and the maximum capacity are the main concern of service providers and it is always a challenging task for them to achieve economically. Because the optimum configuration of a network corresponds to a configuration which minimizes the number of sites required to provide a target service probability in the planning area which in turn reduces the deployment cost. The optimum performance means the maximum cell area and themaximum cell capacity the network can provide at the maximum antenna height satisfying the target service probability. Hexagon layout has been proven as the best layout for the cell deployment. In this thesis work, two different configurations using six-sectored sites have been considered for the performance comparison. In first configuration, each antenna is directed towards each corner of hexagon, whereas in second configurationeach antenna is directed towards each side of hexagon. The net difference in the configurations is the 30 degree rotation of antenna direction. The only indoor users in a flat and smooth semi-urban environment area have been considered for the simulation purpose where the traffic distribution is 100 Erl/km2 with 12.2 kbps speech service having maximum mobile speed of 3 km/hr. The simulation results indicate that a similar performance can be achieved in both the configurations, that is, a maximum of 947 m cellrange at antenna height of 49.5 m can be achieved when the antennas are directed towards the corner of hexagon, whereas 943.3 m cell range atantenna height of 54 m can be achieved when the antennas are directed towards the side of hexagon. However, from the interference point of view the first configuration provides better results. The simulation results also show that the network is coverage limited in both the uplink and downlink direction at the optimum point.

Training needs in adolescent medicine of practising doctors: a Swiss national survey of six disciplines.

OBJECTIVE: To assess and compare the training needs in adolescent medicine of doctors within 6 specialties as a basis for the development of pre/postgraduate and continuing medical education (CME) training curricula. DESIGN: Cross-sectional postal survey. SETTING: Switzerland. PARTICIPANTS: National, representative, random sample of 1857 practising doctors in 6 disciplines (general practitioners, paediatricians, gynaecologists, internists, psychiatrists, child psychiatrists) registered with the Swiss Medical Association. MAIN OUTCOME MEASURES: Perceived importance of and training interest in 35 topics related to adolescent medicine listed in a self-administered, anonymous questionnaire. RESULTS: A total of 1367 questionnaires were returned, representing a response rate of 73.9%. Clear interest in adolescent medicine was reported by 62.1% of respondents. Topics perceived to be the most important in everyday practice were functional symptoms (71.4%), acne (67.1%), obesity (64.6%), depression-anxiety (68.1%) and communication with adolescents (61.7%). Differences between disciplines were especially marked for gynaecologists, who expressed interest almost exclusively in medical topics specific to their field. In contrast, other disciplines commonly reported a keen interest in psychosocial problems. Accordingly, interest in further training was expressed mostly for functional symptoms (62.4%), eating disorders (56.3%), depression-anxiety (53.7%) and obesity (52.6%). Issues related to injury prevention, chronic disease and confidentiality were rated as low priorities. CONCLUSIONS: Regardless of discipline, Swiss primary care doctors expressed a strong interest in adolescent medicine. Continuing medical education courses should include both interdisciplinary courses and discipline-specific sessions. Further training should address epidemiological and legal/ethical issues (e.g. injury prevention, confidentiality, impact of chronic conditions).

Four-corner bone arthrodesis with dorsal rectangular plate: series and personal technique.

Controversy exists about the best method to achieve bone fusion in four-corner arthrodesis. Thirty-five patients who underwent this procedure by our technique were included in the study. Surgical indications were stage II-III SLAC wrist, stage II SNAC wrist and severe traumatic midcarpal joint injury. Mean follow-up was 4.6 years. Mean active flexion and extension were 34 degrees and 30 degrees respectively; grip strength recovery was 79%. Radiological consolidation was achieved in all cases. The mean DASH score was 23 and the postoperative pain improvement by visual analogue scale was statistically significant. Return to work was possible at 4 months for the average patient. Complications were a capitate fracture in one patient and the need for hardware removal in four cases. Four-corner bone wrist arthrodesis by dorsal rectangular plating achieves an acceptable preservation of range of motion with good pain relief, an excellent consolidation rate and minimal complications.

Endovascular treatment of symptomatic intracranial arterial stenosis: six-year experience in a single-center series of 42 consecutive patients with acute and mid-term results.

BACKGROUND: The limitations of the medical management of symptomatic intracranial arterial stenosis encourage the development of new therapeutic strategies such as intracranial stenting. OBJECTIVE: To report and analyze the results of a series of 42 patients treated with 3 different endovascular techniques: isolated angioplasty, balloon-expandable coronary stents, and the Wingspan self-expandable intracranial stent system. METHODS: Forty-two patients presenting with symptomatic intracranial arterial stenosis were treated with one of these techniques. Computed tomography angiography was performed 6 months after the procedure, and the clinical neurological statuses were categorized using the modified Rankin Scale and the National Institutes of Health Stroke Scale. RESULTS: A total of 42 lesions were treated: 9 with isolated angioplasty, 14 with balloon-expandable coronary stents, and 19 with Wingspan self-expandable intracranial stents. The mean patient age was 62.9 years, and the mean arterial diameter stenosis was 73.9%. Technical success was achieved in 97.6% of the patients. The overall incidence of procedural complications was 21.4%, and the postoperative permanent morbidity/mortality rate was 7.1%. There were 3 cases of in-stent thrombosis (1 fatal) and 5 cases of asymptomatic restenosis (11.9%), 3 in the isolated angioplasty group and 2 in the Wingspan self-expandable intracranial stent group (mean follow-up 20.4 months). The rate of restenosis was higher in the angioplasty group (33%) than in the coronary (0%) and Wingspan stent (10.5%) groups. CONCLUSION: Endovascular treatment of symptomatic intracranial stenosis has significant overall morbidity and mortality rates. Nevertheless, the very critical natural history of severe refractory lesions and the relatively favorable postoperative evolution suggest that it should be considered the first alternative strategy in cases in which medical therapy has failed.

An Image Enhancement Technique using MTF of Human eye

Image filtering is a highly demanded approach of image enhancement in digital imaging systems design. It is widely used in television and camera design technologies to improve the quality of an output image to avoid various problems such as image blurring problem thatgains importance in design of displays of large sizes and design of digital cameras. This thesis proposes a new image filtering method basedon visual characteristics of human eye such as MTF. In contrast to the traditional filtering methods based on human visual characteristics this thesis takes into account the anisotropy of the human eye vision. The proposed method is based on laboratory measurements of the human eye MTF and takes into account degradation of the image by the latter. This method improves an image in the way it will be degraded by human eye MTF to give perception of the original image quality. This thesis gives a basic understanding of an image filtering approach and the concept of MTF and describes an algorithm to perform an image enhancement based on MTF of human eye. Performed experiments have shown quite good results according to human evaluation. Suggestions to improve the algorithm are also given for the future improvements.
