Increasing attention has been paid to the next generation of 'green' electronic devices based on renewable nanocellulose, owing to its low roughness, good thermal stability and excellent optical properties. Various proof-of-concept transparent nanopaper-based electronic devices have been fabricated; these devices exhibit excellent flexibility, bendability and even foldability. In this review, w...

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...

Printed electrochromic flexible films were obtained by combining transparent silver grid electrodes formed by self-assembly and inkjet printed WO3 nanoparticles. Concentrated dispersions of WO3 nanoparticles were inkjet printed on transparent plastic silver grid electrodes with a high transparency of 83% in the spectral range of 400-800 nm, and a low sheet resistance in the range of 1-5 Ω sq(-1...

We demonstrate a process to fabricate silicon photonic devices directly on a plastic film which is both flexible and transparent. This process allows the integration of complex structures on plastic films without the need of transferring from another substrate. Waveguides, grating couplers, and microring resonators are fabricated and optically characterized. An optical strain sensor is shown as...

Existing methods for visual recognition based on quantized local features can perform poorly when local features exist on transparent surfaces, such as glass or plastic objects. There are characteristic patterns to the local appearance of transparent objects, but they may not be well captured by distances to individual examples or by a local pattern codebook obtained by vector quantization. The...

This ex vivo study evaluated the quality of digital radiographic images obtained with the photostimulable phosphor plate system (Digora) according to the processing delay and maintenance of optical plates in either opaque (supplied with the system) or transparent protective plastic cases during this period. Five radiographs were obtained from the mandibular molar region of a dry human mandible ...

Devices based on solution processable organic materials are promising for inexpensive large area electronics on transparent fl exible plastic substrates. [ 1 ] In practice, however, electrodes in organic devices typically consist of vacuum deposited materials that are largely incompatible with this goal. The most widely used transparent electrode for plastic electronics to date is tin-doped ind...
