! ABSTRACT —;> Lightning protection of modern aerospace vehicles must prohibit sparking in critical fuel vapor areas. In the past, it has been particularly difficult to keep mechanical fasteners from sparking during a lightning event. Attempts to seal off the fasteners from the critical fuel vapor area by manual application of sealant material have proven to be ineffective due to gaps and voids...

Rezumat Proiectarea asistată de calculator a sistemelor de iluminat realizează dimensionarea unor instalaţii noi de iluminat cât şi verificarea celor existente, atât pentru sistemele de iluminat interior cât şi pentru sistemele de iluminat exterior.

A doped poly(methyl methacrylate) (PMMA)– based graded-index plastic optical fiber (GI POF) with high mechanical strength is reported for the first time. Although the POF is generally believed to have a good mechanical flexibility even if it has a large-core diameter, such a high mechanical strength has been provided by making the polymer chains in the POF highly oriented in its axial direction...

Because the electrical installations are nowadays a lot of options and variants, it is necessary to evaluate these complex installation process from several perspectives and objectively. Due to the complexity of evaluation of electrical installation is design a methodology that uses multi-criteria analysis MCA.

Structure-borne sound transmission is a more complicated process than airborne sound transmission, but practitioners seek methods of prediction for the former, which are as straightforward as for the latter. In this paper a description is given of measurement and calculation procedures where the source activity (the velocity of the source when resiliently supported) and the mobility, and receiv...

This paper presents MINUET, a framework for musical interface design grounded in the experience of the player. MINUET aims to provide new perspectives on the design of musical interfaces, referred to as a general term that comprises digital musical instruments and interactive installations. The ultimate purpose is to reduce the complexity of the design space emphasizing the experience of the pl...

The paper presents the results of technical and economic, theoretical experimental research on transportation chips from cutting zone machine by widely used classic types conveyor transport combined (hydraulic screw). analysis showed that in domestic foreign engineering, which uses integrated installations for sludge area machine, have a number serious shortcomings do not allow to effectively c...
