Book Description
LES CAPOTAGES DE MACHINES SONT SOUVENT UTILISES DANS L'INDUSTRIE POUR REDUIRE LE BRUIT DES MACHINES. ILS SONT RAREMENT INTEGRAUX ET PRESENTENT SOUVENT DES FUITES ACOUSTIQUES, QUI EN REDUISENT CONSIDERABLEMENT L'EFFICACITE. DEUX MODELES ANALYTIQUES ONT ETE ETUDIES PUIS APPLIQUES AU CALCUL DE L'INDICE D'AFFAIBLISSEMENT ACOUSTIQUE D'UNE PAROI CONTENANT UNE FENTE RECTANGULAIRE. UNE ETUDE PARAMETRIQUE A ETE EFFECTUEE POUR METTRE EN EVIDENCE L'INFLUENCE DE LA GEOMETRIE DE L'OUVERTURE ET DE LA FREQUENCE DE L'ONDE INCIDENTE. UNE DEUXIEME PARTIE DECRIT LA DISTRIBUTION SPATIALE DE L'ENERGIE ACOUSTIQUE TRANSMISE PAR LA FENTE. UNE MODELE NUMERIQUE PERMET DE CALCULER LA DIRECTIVITE DU RAYONNEMENT SOUS INCIDENCE NORMALE ET SOUS INCIDENCE OBLIQUE. CE DERNIER CAS EST EGALEMENT TRAITE DANS LES HAUTES FREQUENCES PAR UNE INTEGRALE DE PHASE STATIONNAIRE; UNE RELATION EST ETABLIE ENTRE L'ANGLE PRINCIPAL DE RAYONNEMENT ET L'ANGLE D'INCIDENCE. ENFIN, UN BANC D'EXPERIMENTATION A PERMIS DE VALIDER LES MODELES PRECEDENTS ET DE CONFIRMER L'IMPORTANCE DE LA GEOMETRIE DE L'OUVERTURE SUR LA QUANTITE D'ENERGIE TRANSMISE ET SA DISTRIBUTION SPATIALE

Book Description
Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

Book Description
This new, third volume of Cohen-Tannoudji's groundbreaking textbook covers advanced topics of quantum mechanics such as uncorrelated and correlated identical particles, the quantum theory of the electromagnetic field, absorption, emission and scattering of photons by atoms, and quantum entanglement. Written in a didactically unrivalled manner, the textbook explains the fundamental concepts in seven chapters which are elaborated in accompanying complements that provide more detailed discussions, examples and applications. * Completing the success story: the third and final volume of the quantum mechanics textbook written by 1997 Nobel laureate Claude Cohen-Tannoudji and his colleagues Bernard Diu and Franck Laloë * As easily comprehensible as possible: all steps of the physical background and its mathematical representation are spelled out explicitly * Comprehensive: in addition to the fundamentals themselves, the books comes with a wealth of elaborately explained examples and applications Claude Cohen-Tannoudji was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris where he also studied and received his PhD in 1962. In 1973 he became Professor of atomic and molecular physics at the Collège des France. His main research interests were optical pumping, quantum optics and atom-photon interactions. In 1997, Claude Cohen-Tannoudji, together with Steven Chu and William D. Phillips, was awarded the Nobel Prize in Physics for his research on laser cooling and trapping of neutral atoms. Bernard Diu was Professor at the Denis Diderot University (Paris VII). He was engaged in research at the Laboratory of Theoretical Physics and High Energy where his focus was on strong interactions physics and statistical mechanics. Franck Laloë was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris. His first assignment was with the University of Paris VI before he was appointed to the CNRS, the French National Research Center. His research was focused on optical pumping, statistical mechanics of quantum gases, musical acoustics and the foundations of quantum mechanics.

Book Description
I am pleased to present a work which marks a milestone in the history of public works and, more precisely, in that of permanent structures—a comprehensive dictionary of Civil Engineering terms. Since the beginning of time, Man has always tried to find a means to clear the obstacles which nature erected to displace him. With the first tree trunk thrown across a river, man sought to improve the crossing structure. After the invention of the wheel, and to satisfy his thirst for conquest (Roman ways), and comfort (aqueducts), man built bridges that became a preremptory necessity to move quickly. Thus, Man started to build wooden and masonry works. With the passing centuries, the builders became masters in the art of building masonry works. Then came the Industrial Revolution and the advent of the steel (1864), which was closely followed by the invention of the reinforced concrete (1855). The need for railways and improving the road network inspired great works of crossing such as viaducts and tunnels. The boom of the railway network and the development of the car required the construction of an increasing number of new structures. This phenomenon continues today with hundreds of structures built each year throughout the world.

Book Description
The Treatise on Musical Objects is regarded as Pierre Schaeffer’s most important work on music and its relationship with technology. Schaeffer expands his earlier research in musique concrète to suggest a methodology of working with sounds based on his experiences in radio broadcasting and the recording studio. Drawing on acoustics, physics, and physiology, but also on philosophy and the relationship between subject and object, Schaeffer’s essay summarizes his theoretical and practical work in music composition. Translators Christine North and John Dack present an important book in the history of ideas in Europe that will resonate far beyond electroacoustic music.
