In this position paper, we propose a new mechanism for user authentication using micro expression analysis in addition to face recognition. In our approach, micro expression analysis is used as a supplementary module to face recognition and is used to introduce a live element to the recognition / authentication process.

The anisotropy of wood within the radial-tangential (RT) growth plane has a major influence on the cracking behavior perpendicular to grain. Within the scope of this work, a two-dimensional discrete element model is developed, consisting of beam elements for the representation of the micro structure of wood. Molecular dynamics simulation is used to follow the time evolution of the model system ...

The presented study is motivated by the development of methods, algorithms, and software tools for μFE (micro finite element) simulation of human bones. The voxel representation of the bone microstructure is obtained from a high resolution computer tomography (CT) image. The considered numerical homogenization problem concerns isotropic linear elasticity models at micro and macro levels.

Microelectromechanical Systems (MEMS) is the technology of the very small, and merges at the nano-scale into "Nanoelectromechanical" Systems (NEMS) and Nanotechnology. MEMS are also referred to as micro machines, or Micro Systems Technology (MST). MEMS are separate and distinct from the hypothetical vision of Molecular nanotechnology or Molecular Electronics. MEMS generally range in size from a...

The objective of this study was to investigate the effect of seasonality on nutrient intake in healthy adults from the southernmost metropolitan area of Brazil. The dietary intake (24-hour dietary recall on six different days) in a sample of 162 adults (114 women), aged 20 to 69, was obtained during the year 2007. The nutrient intake was averaged for each season and adjusted for energy intake u...

diagnosis and recommendation integrated system (dris) can be used as efficient methods to interpret the results of plant analysis and the nutritional diagnosis in crops and fruit trees. to establish dris norms in onion (allium cepa l) leaf samples were collected from 50 fields and n, p, k, ca, mg, fe, mn, zn, cu and b concentrations were determined. on the bases of yield, the studied fields wer...

In this paper, we demonstrate a micro-optical wall pressure sensor concept based on the optical modes of dielectric resonators. The sensing element is a spherical micro-resonator with a diameter of a few hundred micrometers. A latex membrane that is flush mounted on the wall transmits the normal pressure to the sensing element. Changes in the wall pressure perturb the sphere's morphology, leadi...

There are three variations of the fermentation process. In batch fermentation, a sterilized nutrient solution in the fermentor is inoculated with micro-organisms and incubation is allowed to proceed. During the course of the fermentation, oxygen is added (as in the case of aerobic microorganisms) and an acid or base to control the pH. The composition of the culture medium, the biomass concentra...

Cyanobacteria are equipped with numerous mechanisms that allow them to survive under conditions of nutrient starvation, some of which are unique to these organisms. This review surveys the molecular mechanisms underlying acclimation responses to nitrogen and phosphorus deprivation, with an emphasis on non-diazotrophic freshwater cyanobacteria. As documented for other micro-organisms, nutrient l...
