Terahertz wave-molecule interactions via CMOS chips : from comb gas sensor with absolute specificity to ultra-stable, miniaturized clock
… structures. They serve as an indicator or "finger-print" of molecules. Thus, a rotational spectrometer with absolute specificity is promising for the analysis of complicated gas mixtures (e.g. human exhaled breath and industrial gas leakage). To utilize this important property, a CMOS …

Fundamental Studies And Applications Of Strong Field Ionization
… a complex mixture based on their mass spectral "finger print". The experiments were carried out in a DC sliced imaging apparatus. For the isomer selective detection experiment, the machine was used simply as a time-of-flight mass spectrometer. The mass spectrum of each isomer was used as "basis …

Modelling and performance evaluation of coupled micro resonator array for artificial nose
… on the CMRA structure performance. With the finger print of the coupled frequency response, the output signal of N multiple resonant sensors is monitored by a single processor; hence, reducing the complexity of readout and signal processing system.

Hardware and User Profiling for Multi-factor Authentication
… for example biometric authentication such as fingerprint recognition or physical tokens such as smart cards. The resulting multifactor authentication is typically stronger than any of the techniques used individually. However, it may still be expensive or prohibited to implement and more …

A study on endocrine disrupters in the environment through the microarray technology
… a fast characterization of the gene expression finger print of the candidate substances and their mechanism of action in the organism. In my work I investigated the estrogenic potency of different Xenoestrogens that commonly occur in our daily life, in rat cells and tissue using well known …

Turbulent Exchange of Ozone and Nitrogen Oxides between an Amazonian Rain Forest and the Atmosphere
… the frequent appearance of ramp pattern, the “finger print” of coherent turbulent structures. This enabled (i) to estimate a mean residence time of air within the part of the canopy which is directly coupled to the atmosphere above by these short, extreme, exchange events, and (ii) to determine …

Diagnetic modelling in Middle Jurassic clastic sediments from the Ravenscar group, Yorkshire, and the Brent group, northern North Sea
… established during eogenesis, this climatic "finger print" may be recognised in all these sediments despite their subsequent diverse history.

Transform Based And Search Aware Text Compression Schemes And Compressed Domain Text Retrieval
… classes of images such as medical imaging, finger print data, astronomical images and data bases containing mostly vital numerical data, tables and text information. Many lossy algorithms use lossless methods at the final stage of the encoding stage underscoring the importance of lossless …

Energy Recovery from Oil Sands Reservoirs
Alberta's oil sands are the third largest proven crude oil reserve in the world, after Saudi Arabia and Venezuela. The proven reserve is ~165.4 billion barrels. At original reservoir conditions, for in-situ methods, the bitumen is too viscous to extract directly with viscosities of the order of …

Modelo de redes complejas mediante enlace compatible : aplicación a sistemas reales
… properties of small world networks seem to be a finger print of the so called complex networks. The presence of complexity can be explained, at least intuitively, as an effect of evolution in natural systems. The time and the mechanisms associated to this process would play an important role in …
