Cortisol, a hormone commonly released upon increased stress level, is a biomarker for numerous diseases and plays an important role in the regulation of various physiological processes. Normally a cortisol level is elevated in oral saliva during the time of anxiety and depression. A portable biosensor device could provide an interesting digital instrument to the patients and people who desire precautionary...
A system based on fiber spectrometer was designed to detect the concentration of various artificial pigments contained in the solution. Using this system, the absorbance curves of five kinds of artificial colors of lemon yellow, sunset yellow, carmine, bright blue and amaranth were measured, and the absorption coefficient of each pigment at different wavelengths was calculated. The reliability of...
In order to conveniently measure the concentration of artificial pigments in different solutions, a portable measurement system was developed based on miniature fiber optic spectrometer (MFOS). With this system, the absorbance curves and the absorption coefficients in the visible band for five kinds of artificial pigments in different solutions were measured and calculated. By measuring the concentration...
This paper addresses the power transformer tank design optimization problem and, proposes a tank mechanical property analysis method with high calculation precision. The main contributions of this research are: 1) introduction of a new effective method to calculate transformer tank mechanical property; 2) incorporation of Quantum behaved Particle Swarm Optimization (QPSO) algorithm to solve the tank...
In this letter, we propose an improved version of generalized eigenvalue proximal support vector machine (GEPSVM), called IGEPSVM for short. The main improvements are 1) the generalized eigenvalue decomposition is replaced by the standard eigenvalue decomposition, resulting in simpler optimization problems without the possible singularity. 2) An extra meaningful parameter is introduced, resulting...
With the increased interest in the Web services composition, more and more enterprises and businesses depend on this paradigm. Open, distributed and dynamic properties of the schema, there is a pressing need for secure services in daily transactions. Orchestration and choreography language provide basic services standards and interaction, collaboration, and negotiation standards among services, but...
There is a pressing need for secure services composition in agenda transactions. Orchestration and choreography language provide basic services and interaction, collaboration, and negotiation standards among services, but they don't give any secure manners or secure operation styles and specifications. Despite the interest of such security mechanisms, a formal module of them is still lacking. For...
