Svaizer ITC-IRST I-38050 Povo di Trento (Italy) ABSTRACT This orresponden e reports on the use of CrosspowerSpe trum Phase (CSP) analysis as an a urate Time Delay Estimation (TDE) te hnique. It is used in a mi rophone array system for the lo ation of a ousti events in noisy and reverberant environments. A orresponding Coheren e Measure and its graphi al representation are...

The layered rigid organization of traditional network service stack currently poses a two fold problem: (i) better solutions/improvements cannot be practically deployed in the service stack –we call this the ‘Evolution’ problem, and (ii) applications are becoming more selective and critically demanding for specialized services –we call this the ‘Implementation Conflict’ problem. The ‘Programmab...

The development of a new concept called Technology Development Envelope (TDE) is presented in this paper. The TDE is developed to transform the technology roadmapping approach to the level in which it is dynamic, flexible, and operationalizable. This new approach provides an effective way to help organizations to overcome the challenge of keeping a roadmap alive. The paper emphasizes how the AH...

Fire-tower is effectively applied in forest fire prevention and commanding system, especially in fire monitor and position. After explaining the significance of scientific planning of fire-tower, this paper analyzes GIS`s functions in building forest fire prevention system. This paper uses case study method, which designs a model, fire tower planning and analysis, based on MapGIS platform. Afte...

The study of terrestrial geomicrobiology and its relationship to rock weathering processes is an essential tool in developing analogues for similar processes that may have occurred on Mars. Most studies of manganese-enhanced rock varnish have focused on samples taken from warm arid desert regions. Here, we examine samples obtained from eolian-abraded lava flows of the 4700-4800 m high Ashikule ...

The effects of a typical glaze ice accretion shape on the performance of the M2129 S-duct inlet are computationally investigated for a range of flight Mach numbers. A Reynolds-Averaged Navier-Stokes (RANS) code with k-o> turbulence model is used to simulate the compressible viscous flow in the S-duct inlet. The glaze ice accretion on the cowl lip is modeled on a steady-state basis f rom N A S A...

The aim of this study was to assess whether surface treatment improves zirconia-porcelain adhesion. The 3Y-TZP blocks were cut into squares, then polished and sintered. The zirconia surface treatments were performed as follows: no treatment (C); tribochemical silica coating (TBS); glaze application + hydrofluoric acid etching (GA); glaze application + hydrofluoric acid etching + silanization (G...
