The effect of blue light (400–500 nm) removal on the elongation of Scots pine (Pinus sylvetris L.) seedlings was investigated in a field experiment in Northern Finland during two growing seasons. The seedlings were grown in plexiglass chambers and ambient control plots. The blue wavelengths were removed from the light spectrum by using chambers made of orange plexiglass. The results of nearly d...

This paper describes a work in progress aiming at linking the two largest Italian lexical-semantic databases ItalWordNet and PAROLE-SIMPLE-CLIPS. The adopted linking methodology, the software tool devised and implemented for this purpose and the results of the first mapping phase regarding 1OrderEntities are illustrated here.

Our purpose is to propose and discuss the latest version of an integrated method for dialogue analysis, annotation and evaluation., using a set of different pragmatic parameters. The annotation scheme Pr.A.Ti.D was built up on task-oriented dialogues. Dialogues are part of the CLIPS corpus of spoken Italian, which consists of spoken material stratified as regard as the diatopic variation. A des...

At the high energy density experimental area (HHT), strongly coupled plasmas are created by the interaction of the SIS heavy ion beams with solid targets. Presently, the generated plasmas have densities close to the solid state, large volumes of several mm and temperatures up to 1 eV. Besides experiments of direct matter heating by heavy ion beams, a complete study of the low entropy shock comp...

An implementation system of three-dimensional endoscopic photoacoustic imaging is presented. The developed endoscopic photoacoustic detector integrates a multielement linear transducer array, a reflective device, a Plexiglass tube, and ultrasonic coupling medium. To match with the acoustic impendence of Plexiglass tube, a glycerin solution with 45% volume percentage was used as the ultrasonic c...

Resumo: A utilização de sistemas de conhecimento em problemas que não são totalmente conhecidos ou bem definidos permite entender esses problemas de maneira exploratória, simulando situações e soluções utilizando técnicas de inteligência artificial. A abordagem inicial utilizada nos projetos de pesquisa do grupo tinha como foco apenas verificar a presença de atributos de transparência em modelo...

Optical holographic interferometry was used to study standing sound waves in air inside a resonance tube driven by a small loudspeaker at one end. The front face of the resonance tube was constructed of plexiglass, allowing optical interrogation of the tube interior. The object beam of the holographic setup was directed through the plexiglass and reflected off the back wall of the resonator. Wh...
