Given suitable conditions of air temperature and humidity, the density of a fog and its microphysical properties depend mainly on the availability of cloud condensation nuclei (CCN) and their nature. Fogs become particularly dense near certain industrial plants because of high concentration of hygroscopic combustion particles in the air. Their role in dense fog formation is estimated by comparing the local climates and CCN concentrations at two similar sites, the first being more subject to air pollution and dense fogs than the second. Orthogonal regression is applied to three meteorological variables (air temperature, relative humidity, wind speed) and CCN concentration. As we compare very close variables, bootstrap provides precise confidence intervals independent of Gaussian assumptions. Two sites are compared: they are located in the Meuse valley (Belgium) at a distance of about 15 km. We found that the local climate of the polluted site is not only colder and wetter but also richer in CCN that the control site. These results suggest interactions of natural and anthropogenic causes in dense fog formation at industrial site. This method is useful in various domains of geophysics when correlated time series have to be compared. [less ▲]

PROBLEM TO BE SOLVED: To obtain a (co)polymer excellent in resistance to thermal decomposition by polymerizing or copolymerizing a monomer or monomers in the presence of an initiation system contg. a free-radical generator other than a bromoolefin and a catalyst comprising a Pd complex having an oxidation number of 0 and represented by a specific formula. SOLUTION: A Pd salt (e.g. Pd acetate), a ligand (e.g. triphenylphosphine), and a solvent (e.g. toluene) are charged into a reactor to form a Pd complex having an oxidation number of 0 and represented by the formula: Pd(0)L<1> L<2> L<3> L<4> [wherein L<1> to L<4> are each a ligand such as PRR'R'' (wherein R, R', and R'' are each 1-14C alkyl, etc.)]. Then, a monomer (e.g. methyl methacrylate) is added to the reactor followed by the addition of a free-radical generator (e.g. CCl4 ) in a molar ratio of Pd to the generator of 0.01-100.; The contents in the reactor are heated to 40-90 deg.C and stirred for a certain time to conduct the polymn. The reaction mixture is diluted with toluene, etc., filtered, and condensed under a reduced pressure. The resultant polymer soln. is poured into methanol, etc., and the resultant precipitate is filtered, washed, and dried to give a polymer having a number average mol.wt. of 400-10,000,000g/mol and a polydispersity lower than 2.

Modal analysis is used extensively for understanding the dynamic behavior of structures. However, a major concern for structural dynamicists is that its validity is limited to linear structures. New developments have been proposed in order to examine nonlinear systems, among which the theory based on nonlinear normal modes is indubitably the most appealing. In this paper, a different approach is adopted, and proper orthogonal decomposition is considered. The modes extracted from the decomposition may serve two purposes, namely order reduction by projecting high-dimensional data into a lower-dimensional space and feature extraction by revealing relevant but unexpected structure hidden in the data. The utility of the method for dynamic characterization and order reduction of linear and nonlinear mechanical systems is demonstrated in this study. [less ▲]

This article presents the method developed to assess existing suburban neighbourhoods in order to improve their energy efficiency. It combines the use of dynamic simulation tools to evaluate energy requirements for heating and lighting residential buildings, a statistical approach to assess the transport system and a simplified calculation to take also into account public lighting. The method is completed by a life-cycle analysis of buildings. An application is presented concerning the comparison of three typical suburban structures in the Walloon region of Belgium. The influence of parameters which are often underestimated, like distribution of buildings or location, on the global energy performances of suburban fabrics is tested. The results of this exercise are presented and its limits are discussed. [less ▲]

This paper focuses on the development of a new evaluation method that combines data obtained by two different approaches: “multizonal dynamics” and “computational fluid dynamics (CFD)”. This research is a part of a project whose the main objective is to define guidelines for architects and buildings engineers. This guidelines aims at determining the adequate approach needed to evaluate the occupant thermal comfort and the building energy consumption for cooling and heating. [less ▲]

Solar simulation and evaluation tools are essential for the design of novel energy and environmental strategies. To date, a number published studies in this area focused on the analysis of flat roofs and small urban areas. This paper presents a method, based on Geographic Information Systems (GIS), for defining the potential of photovoltaic solar energy over urban faßcades. The method enables the generation of 3D solar maps from two standard data sources, namely cadastral cartography and data on solar irradiance registered by the Spanish State Meteorological Agency (AEMET, for its initials in Spanish). A series of charts have been generated relating the urban and solar geometries as a result of the numerical model. The charts permit the study of the optimal parameters for the photovoltaic integration over faßcades. In addition, a study conducted over a representative urban area of Madrid is discussed as an example of the applicability of the discussed methodology. Finally, the adequacy of the Spanish Technical Edification Code (CTE, for its initials in Spanish), defining thresholds regarding the usability of photovoltaic energy, has been tested both theoretically and through the case study. Our study concludes that this regulation hinders the architectural integration of photovoltaic devices given the strict usability thresholds adopted. [less ▲]

Energy use in buildings, transportation systems and lighting networks represents a significant contribution to the overall energy consumption in urban and suburban areas. This paper presents a method to evaluate the energy consumption of suburban neighborhoods from these three points of view, aiming to highlight the most relevant variables linking urban form and neighborhoods energy consumptions. The method includes three parts: 1) a computational approach combining dynamic simulation tools and a database of building typologies to determine the energy consumed in heating; 2) an empirical approach to assess the energy consumed by transportation systems (four purposes of travel are taking into account: work, school, leisure and shopping); and 3) a simplified approach to calculate the energy consumed by public lighting. Results from the application of the method to three characteristic suburban neighborhoods in Belgium are presented along with a life cycle energy assessment of buildings. A sensitivity analysis was conducted to determine the effects of building and neighborhood characteristics and of building inhabitant behavior on calculated energy consumption. Results from the analysis show that building insulation, building distribution, heating system management and neighborhood location are critically important factors in the energy efficiency of suburban residential areas.

A method is proposed to optimize the definition of existing photometric filters in order to minimize passband-matching problems. It is argued that the "improved" systems should generally yield better astrophysical parameters than the original ones. Although of a general scope, the method is checked on intermediate-passband filters of the Stroemgren system. [less ▲]
