The aim of this project was to synthesise nanosensors. It can be defined as an inert, biofriendly matrix in which sensing molecules are entrapped, allowing determination of analytes concentration. Two types of nanosensors were synthesised according to the Stöber method and characterised by a scanning electron microscope and a CPS disc centrifuge. The nanosensors were calibrated with succes using a fluorimeter. [less ▲]

Executive functioning (EF) is an umbrella term used to refer to the higher-order cognitive processes whose principal function is to facilitate the adaptation of an individual to new and non-routine situations. In the present study, inhibition, mental flexibility, and working memory were assessed through 6 executive tasks administered to 329 children aged from 4 to 11 years, in order to examine the development and organization of executive functioning in both early and middle childhood. Results reveal specific developmental trends for each component, with a period of rapid general development during the preschool period. Confirmatory factor analyses were used to examine the organization of EF in our sample. First, the poorness of fit of the unitary model was found for both groups, confirming the fractionated nature of EF in preschoolers as well as in older children. Second, the analyses confirmed the adequacy of the fit of the three-dimensional model (i.e., inhibition, flexibility, and working memory), while also indicating that other specific two-dimensional models gave reasonable fits to the data from both age groups. The factor structure obtained supports both the unitary and diversity nature of the executive organisation during early and middle childhood. Furthermore, our data suggest a progressive differentiation of executive processes (in particular flexibility and working memory) in the course of development. [less ▲]

Several finite element (FE) simulations were investigated using a recently developed mixed type element: the BWD3D. The main formulation of the element is largely described, with particular focus on the shear locking treatment. The formulation of the former BLZ3D element is also presented for comparison. The examples investigated in the present study were beam bending, large strain torsion, incremental forming and deep drawing .The numerical results obtained with both elements were compared to experiments.

The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument is one of a handful of extreme adaptive optics systems set to come online in 2014. The extreme adaptive optics correction is realized by a combination of precise wavefront sensing via a non-modulated pyramid wavefront sensor and a 2000 element deformable mirror. This system has recently begun on-sky commissioning and was operated in closed loop for several minutes at a time with a loop speed of 800 Hz, on ~150 modes. Further suppression of quasi-static speckles is possible via a process called "speckle nulling" which can create a dark hole in a portion of the frame allowing for an enhancement in contrast, and has been successfully tested on-sky. In addition to the wavefront correction there are a suite of coronagraphs on board to null out the host star which include the phase induced amplitude apodization (PIAA), the vector vortex, 8 octant phase mask, 4 quadrant phase mask and shaped pupil versions which operate in the NIR (y-K bands). The PIAA and vector vortex will allow for high contrast imaging down to an angular separation of 1 λ/D to be reached; a factor of 3 closer in than other extreme AO systems. Making use of the left over visible light not used by the wavefront sensor is VAMPIRES and FIRST. These modules are based on aperture masking interferometry and allow for sub-diffraction limited imaging with moderate contrasts of ~100-1000:1. Both modules have undergone initial testing on-sky and are set to be fully commissioned by the end of 2014. [less ▲]

A series of new simulation tools are being developed to help the building energy auditor in establishing his diagnosis (including benchmarking and detailed analysis of actual energy consumption) and in evaluating the selected Energy Conservation Opportunities (ECOs). The Building-HVAC System global models presented here include simplified models of building zones and of HVAC equipment. Only a limited number of easily identifiable parameters is required. The simplicity of the models and the use of an equation solver to run the simulation ensure good robustness and full transparency. The development, the implementation and the use of these models are discussed in the present paper. Focus is also given to the calibration of the tools to the monthly utility bills. [less ▲]

A specific formula to calculate separation distance from piggeries and poultry facilities to sensitive receptor is developed for Walloon Region, in Belgium. The paper briefly presents the main principles of the formula and discusses more deeply the compatibility of the distance approach with odour units, odour rate and percentiles usually applied to assess the odour annoyance zones. A method of validation is presented and tested to adjust the different parameters of the formula to Belgian field reality. A total of 43 farms of which 21 piggeries and 22 poultry facilities are visited and, for each case, the distance calculated by the formula is compared to the one deduced from odour annoyance criterion (10 ou m-3 at 98th percentile). Validation work results in discussing the sensibility of different factors of the formula and especially in adjusting a fitting factor to match the absolute distances to real field annoyance impression. Conclusions show that both approaches - separation distance formula and percentile evaluation - are coherent. The validation method allows parameter adjustment but should need further refinements to examine separately piggeries and poultry facilities. [less ▲]
