The state of the art of wave field synthesis (WFS) systems is that they can reproduce sound sources and secondary (mirror image) sources with natural spaciousness in a horizontal plane, and thus perform satisfactory 2D auralization of an enclosed space, based on multitrace impulse response data measured or simulated along a 2D microphone array. However, waves propagating with a nonzero elevatio...

This paper presents the results of a study performed to develop a computational model of cooling ceiling systems. This one has to be used in situ, as diagnosis tool in commissioning process in order to determine the main operating conditions of the system in cooling mode. The model considers the cooling ceiling as a fin. Only the dry regime is considered. From ceiling and room dimensions, mater...

INTRODUCTION Disability and Physical Function (PF) outcome assessment has had limited ability to measure functional status at the floor (very poor functional abilities) or the ceiling (very high functional abilities). We sought to identify, develop and evaluate new floor and ceiling items to enable broader and more precise assessment of PF outcomes for the NIH Patient-Reported-Outcomes Measurem...

The culturable microbial populations in dripping waters from Altamira cave were studied and compared with those of the ceiling rock. Water communities have low proportions of gram-positive bacteria, and are mainly composed of gram-negative rods and cocci (Enterobacteriaceae and Vibrionaceae), while those of ceiling rocks are mainly Streptomyces spp. The community differences are probably relate...

This paper presents the AAected Set Priority Ceiling (ASPC) concurrency control protocol for real-time object-oriented databases. The protocol is based on a combination of a semantic locking technique and priority ceiling techniques. The paper speciies six criteria for real-time concurrency control: high concurrency, deadlock prevention, predictability, temporal consistency enforcement, logical...

This paper provides the explicit expression of investment facing a binding debt ceiling and the explicit expression of the Lagrange multipliers related to the binding debt ceiling constraint. This result allows us to check for misspecification of the parameterizations of these Lagrange multipliers used in Euler investment equations tests during the 1990’s.  2000 Elsevier Science S.A.

Photographic survey techniques were employed ceiling of the Queen’s Staircase at Hampton Court Palace mounted on an 8 metre telescopic mast, raised to approximately 60 cm below the ceiling images were taken from a fixed camera position method was applied with images from ten lamp positions map. Cross-sections at the estimated surface resolution of 7.7 pixels/mm, resolution of approximately 100 ...
