An inherent obstacle in current mobile applications is the limited output capabilities of mobile phones. This paper describes a solution to this limitation that is based on a combination of a public display and Near Field Communication (NFC) technology. The public display, represented by a projection in the developed prototype, is augmented with a matrix of NFC tags whereby each tag is analogou...

The field of artificial vision could greatly benefit from the use of smart bio-inspired vision sensors capable of extracting relevant information from the luminosity signal, instead of simply sampling the external world at fixed time intervals. State-of-the-art neuromorphic vision sensors asynchronously convey information about local variations of input signals, either over time or over space. ...

The performance of face verification systems has steadily improved over the last few years. Stateof-the-art methods use the projection of the gray-scale face image into a Linear Discriminant subspace as input of a classifier such as Support Vector Machines or Multi-layer Perceptrons. Unfortunately, these classifiers involve thousands of parameters that are difficult to store on a smart-card for...

We present a simulation environment for parallel optoelectronic data-processing systems, and we especially consider the fusion of optoelectronic integrated circuits and optical interconnection modules. hadlop, which stands for hardware description language for optical processing, is a simulator that works at the digital design level. So far, hadlop has allowed algorithm and architecture studies...

one of the most important parameters in evaluating a watermarking algorithm is its capacity. generally, watermarking capacity is expressed by bits per pixel (bpp) unit measure. but this measure does not show what the side effects would be on image quality, watermark robustness and capacity. in this paper we propose a three dimensional measure named capacity surface which shows the effects of ca...

Smart cities can be controlled in all aspects and it is desired to have a structure that planned controllable feedback. Asphalt generally used as pavement material on roads provide transportation of vehicles such cars buses the highway. deformed due weather conditions, heavy vehicle passage. In smart city structure, similar deformations should reported relevant unit. this article, was tried det...

I ncreasingly powerful integrated circuits are making an entire range of new applications possible. Complementary metal-oxide semiconductor (CMOS) sensors, for example, have made the digital camera a commonplace consumer item. These light-sensitive chips, positioned where film would normally be, capture images as reusable digital files that users can upload to their computer, manipulate with so...

at present, the solutions to prevent bedsore include using various techniques for movement and displacement of patients, which is not  possible for some patients or dangerous for some of them while it also poses problems for health care providers. on the other hand, development of information technology in the health care system including application of wireless sensor networks (wsns) has led t...
