Outlier detection techniques in spatial data should allow to identify two types of outliers: global and local ones. Local outliers typically have non-spatial attributes that strongly differ from those observed on their neighbors. Detecting local outliers requires to be able to work locally, on neighborhoods, in order to take into account the spatial dependence between the statistical units under consideration, even though the outlyingness is usually measured on the non-spatial variables. Many procedures have been outlined in the literature, but their number reduces when one wants to deal with multivariate non-spatial attributes. In this paper, focus is on the multivariate context. A review of existing procedures is done. A new approach, based on a two-step improvement of an existing one, is also designed and compared with the benchmarked methods by means of examples and simulations. [less ▲]

In addition to the development of a satisfactory test procedure and recommendations to improve the overall quality of concrete repair works, the authors of this proposal intend to collaborate with various representatives from public agencies and from the industry to facilitate technological transfer. Presentations will be made in conferences and workshops in North America and Europe. At the end of the project, the results shall include two MSc theses and at least two papers in major journals, such as Concrete International or ACI Materials Journal. Also, the project should provide the basis towards a standard procedure for the evaluation of superficial cohesion of concrete, in relation with surface preparation and concrete removal techniques. Finally, recommendations and specifications could be incorporated in future versions of the ACI-ICRI Manual of Concrete Repairs as well as in DOT’s specifications. [less ▲]

This manuscript presents an experimental method to estimate a radiation pattern obtained in a particular echoic environment (for example from in-situ measurements) as if measurements were performed in a given anechoic chamber. The correction is achieved using some reference measurements collected both in echoic and anechoic environments. An angular transfer function is estimated from these two sets of measurements and deconvolved from the measured radiation pattern to be corrected. [less ▲]

Context: Constraints on the internal rotation of red giants are now available thanks to asteroseismic observations. Preliminary comparisons with rotating stellar models indicate that an undetermined additional process for the internal transport of angular momentum is required in addition to purely hydrodynamic processes. Aims: We investigate how asteroseismic measurements of red giants can help us characterize the additional transport mechanism. Methods: We first determine the efficiency of the missing transport mechanism for the low-mass red giant KIC 7341231 by computing rotating models that include an additional viscosity corresponding to this process. We then discuss the change in the efficiency of this transport of angular momentum with the mass, metallicity and evolutionary stage. Results: In the case of the low-mass red giant KIC 7341231, we find that the viscosity corresponding to the additional mechanism is constrained to the range 1 x 10^3 - 1.3 x 10^4 cm^2/s. This constraint on the efficiency of the unknown additional transport mechanism during the post-main sequence is obtained independently of any specific assumption about the modelling of rotational effects during the pre-main sequence and the main sequence (in particular, the braking of the surface by magnetized winds and the efficiency of the internal transport of angular momentum before the post-main-sequence phase). When we assume that the additional transport mechanism is at work during the whole evolution of the star together with a solar-calibrated braking of the surface by magnetized winds, the range of nu_add is reduced to 1 - 4 x 10^3 cm^2/s. In addition to being sensitive to the evolutionary stage of the star, we show that the efficiency of the unknown process for internal transport of angular momentum increases with the stellar mass.

Several energy efficiency concepts and comfort models emerged in the last 15 years seeking high performance buildings and optimal occupant comfort conditions. The aim of high performance buildings is to reduce the carbon footprint and energy consumption of buildings while maintain a fit to purpose comfort. In this context, this work raises the question of fir to purpose comfort models that can from one side reduce the energy consumption of typical office buildings in hot climates (cooling dominated) while on the other side ensuring indoor thermal comfort. Indeed, studies that address energy efficiency are many, however it is in most cases applied to temperate or cold climates and barely explored for hot climates. The objective of this paper is to (1) combine several comfort models for a net zero energy building in hot climates, (2) select the comfort model that shows the optimal comfort quality of indoor environment and (3) compare the building's annual energy consumption for each used comfort model. To respond to our research problems, a methodology has been established, which goes through several phases. First identifying the different comfort models comfortable to use in hot climates (ISO 7730 / EN 15251 / adaptive ASHRAE / Givoni), secondly selecting a typical validated office building model as a reference building and finally selecting representative cities in the Mediterranean arid and hot climate (Algiers / Sicily / Cairo / Dubai). The study used building performance simulation to generate the different results on the energy consumption and the operative temperatures of the different models of comfort in each city. The paper ultimately identifies the fit to purpose comfort models for a medium size net zero energy office building in hot climates. The paper presents a comparison that can help building professional to identify the most appropriate comfort model that allows optimizing energy consumption, ensuring thermal comfort for robust perfromnce of net zero energy buildings in hot climates.
