Rapid prototyping of complete systems, the case study of a smart parking

International audienceThis paper details how LINC a coordination middle-ware, can fasten the development of prototypes that integrate several equipment. A case study of rapid prototyping is presented. It illustrates how a smart parking prototype has been built from several independent and autonomous equipment, coming from different vendors. This has been achieved by parallel development thanks to the resource based approach offered by LINC. This paper also describes how LINC helps building rich user interfaces quickly and easily. I. INTRODUCTION Embedded systems have been part of our daily life for decades. Most of the industrial or consumer products embed multiple processors, sensors and actuators. The next step is the opportunity to build new products, systems, and usages, combining together several of these products. In such innovative and quickly evolving context it is necessary to build prototypes to test, validate, and challenge new products usages or solutions. This paper considers prototypes including several equipment, possibly from different vendors. Such prototypes can be used to exhibit demonstrations in a trade fair, to convince investors of the viability of an idea or to verify the adequacy of the solutions for early adopters. To succeed in today's highly competitive market, a prototype should be more than a few items wired together with a command line interface. Targeted prototypes are real-life demonstrations of new products or technologies with a high end-user experience. Moreover, a prototype should be included in its targeted environment (e.g. a house, a building or a parking). The development of prototypes is vital during the validation stage of new products as they may help to

Dynamic Reconfiguration of Building Automation Systems with LINC

This paper details a new approach for dynamic reconfiguration of building automation systems. To achieve dynamic reconfiguration in this context we rely on LINC, a coordination middleware that provides an abstraction layer allowing the encapsulation of hardware and software components. This paper shows two aspects of dynamic reconfiguration: one using the LINC middleware as an intermediation layer and one using LINC to reconfigure autonomous building management systems. A case study is presented. It consists in the reconfiguration of a room that can be split in two or merged in one according to the current needs. The building is equipped with the LON system, a standard in building automation. Such a reconfiguration is normally done manually by a skilled technician. Thanks to the proposed approach, it can now be autonomous and triggered by various external events such as sensor readings, a remote controller or information from an agenda

Second-look surgery plus hyperthermic intraperitoneal chemotherapy versus surveillance in patients at high risk of developing colorectal peritoneal metastases (PROPHYLOCHIP-PRODIGE 15): a randomised, phase 3 study

International audienceBackground Diagnosis and treatment of colorectal peritoneal metastases at an early stage, before the onset of signs, could improve patient survival. We aimed to compare the survival benefit of systematic second-look surgery plus hyperthermic intraperitoneal chemotherapy (HIPEC), with surveillance, in patients at high risk of developing colorectal peritoneal metastases. Methods We did an open-label, randomised, phase 3 study in 23 hospitals in France. Eligible patients were aged 18-70 years and had a primary colorectal cancer with synchronous and localised colorectal peritoneal metastases removed during tumour resection, resected ovarian metastases, or a perforated tumour. Patients were randomly assigned (1:1) to surveillance or second-look surgery plus oxaliplatin-HIPEC (oxaliplatin 460 mg/m(2), or oxaliplatin 300 mg/m(2) plus irinotecan 200 mg/m(2), plus intravenous fluorouracil 400 mg/m(2)), or mitomycin-HIPEC (mitomycin 35 mg/m(2)) alone in case of neuropathy, after 6 months of adjuvant systemic chemotherapy with no signs of disease recurrence. Randomisation was done via a web-based system, with stratification by treatment centre, nodal status, and risk factors for colorectal peritoneal metastases. Second-look surgery consisted of a complete exploration of the abdominal cavity via xyphopubic incision, and resection of all peritoneal implants if resectable. Surveillance after resection of colorectal cancer was done according to the French Guidelines. The primary outcome was 3-year disease free survival, defined as the time from randomisation to peritoneal or distant disease recurrence, or death from any cause, whichever occurred first, analysed by intention to treat. Surgical complications were assessed in the second look surgery group only. This study was registered at ClinicalTrials.gov, NCT01226394. Findings Between June 11, 2010, and March 31, 2015, 150 patients were recruited and randomly assigned to a treatment group (75 per group). After a median follow-up of 50.8 months (IQR 47.0-54.8), 3-year disease-free survival was 53% (95% CI 41-64) in the surveillance group versus 44% (33-56) in the second-look surgery group (hazard ratio 0.97, 95% CI 0.61-1.56). No treatment-related deaths were reported. 29 (41%) of 71 patients in the second-look surgery group had grade 3-4 complications. The most common grade 3-4 complications were intra-abdominal adverse events (haemorrhage, digestive leakage) in 12 (23%) of 71 patients and haematological adverse events in 13 (18%) of 71 patients. Interpretation Systematic second-look surgery plus oxaliplatin-HIPEC did not improve disease-free survival compared with standard surveillance. Currently, essential surveillance of patients at high risk of developing colorectal peritoneal metastases appears to be adequate and effective in terms of survival outcomes.

L’habitat et l’occupation des sols à l’âge du Bronze et au début du premier âge du Fer

National audienceThe Bronze Age cultures have long been arduous for archaeologists to determine because of their diverse manifestations and tenuous remnants. It took more than 25 years of rescue archaeological research to understand that the Bronze Age is very likely a key period in the emergence of pre-state hierarchical societies and in the construction of our environment. This publication is a first national synthesis, region by region, of a research program still in progress, the “Bronze” national survey. This work of processing and interpreting archaeological and palaeoenvironmental data made it possible to assess the status of rural installations, to measure the ties that unite these spaces to form a network of settlements and to systematize the symbolic appropriation of places by these communities. This work also highlights the place in which natural environments are often considered, wrongfully, as marginal, in the early days of the diversification of socio-economic systems.Les cultures de l’âge du Bronze ont longtemps été ardues à déterminer pour les archéologues tant leurs manifestations sont diverses et leurs vestiges ténus. Il aura fallu plus de 25 ans de recherche archéologique préventive pour comprendre que l’âge du Bronze constitue très probablement une période clé dans l’émergence des sociétés hiérarchisées pré-étatiques et dans la construction de notre environnement.Cet ouvrage est une première synthèse à l’échelle nationale, région par région, d’un programme de recherche toujours en cours, l’enquête nationale Bronze. Ce travail d’exploitation et d’interprétation des données archéologiques et paléoenvironnementales a permis d’apprécier le statut des installations rurales, de mesurer les liens qui unissent ces espaces pour former des réseaux de peuplement et de systématiser l’appropriation symbolique des lieux par ces populations. Il révèle également la place de milieux naturels souvent considérés, à tort, comme marginaux, dans les débuts de la diversification des systèmes socio-économiques
