Today's business environment for the cement producers is becoming more challenging. Rising production costs and environmental regulations are only two of the main limiting factors. One proven solution is the use of alternative fuels, whereby especially the influence of such fuels to the production-process and pyro-pro…
This paper focused on the existent technology problems in the dilute acid delinting of cotton seed, it first introduced the traditional process of dilute acid delinting, then combined with the automatic control technology and information processing technology of the controling of concentration, temperature and so on d…
The current signal of the dirty high-voltage is non-stationary signals, which contains rich characteristics and the extent of the information of the insulator flashover, in order to accurately extract these features we can use Hilbert-Huang transformation (HHT) method which has developed in recent years. EMD is the co…
Abstract : Exposure of nanoparticles of Ag to 2-CEES (2-chloroethyl ethylsulfide, a simulant of the sulfur mustard warfare agent) was found to cause a significant change in the film conduction characteristics that could be used as a sensitive method of detection. Ag nanoparticles deposited onto highly-ordered pyroliti…
Classical scrapie disease is a transmissible spongiform encephalopathy of sheep that is enzootic in the United States. Susceptibility of sheep to classical scrapie is linked to single nucleotide polymorphisms in the prion protein gene (PRNP), forming the basis for genetic testing strategies used by national efforts to…
The dielectric breakdown voltage of an insulating liquid is important as a measure of the liquid's ability to withstand electric stress. The parameters of the standard test methods from different countries are not similar. In the different standards there are used five or six single breakdowns in a glass or a plastic…
We propose a morphological quantitative evaluation method for the aging analysis of the handback skin. First of all, the non-invasive method of digital imaging technology is adopted to get the handback skin morphological data. Then, based on the algorithms of gray-level co-occurrence matrix and displacement co-occurre…
Several reactor designs for continuous production of finely dispersed metal oxides by “wet burning” were developed and tested. Basic dimensions of the reactors were determined on the basis of calculations of the specific heat release and gas evolution, and laboratory prototypes of the reactors were fabricated and test…
Tissue engineering is one of the important approaches for both soft and hard tissue repair and reconstruction. In this approach, scaffolds having highly and open pore structures which would allow an efficient vascularization and therefore the active 3D-cell growth are required. These scaffolds can be used to create so…
Linear induction motor (LIM) drives have been investigated vastly for the past several decades. Attractive features, such as simple structure and easy maintenance, have made this family of machines utilized broadly in military, transportation, and aerospace, to name a few. Vector control is a dominant control strategy…
A new kind of induction motor with compound cage rotor(IMCCR) is developed in this paper, in which rotor bar is composed of upper part made of alloy material (conductor of electric and magnetic) and lower part made of cast aluminum. The transient heat conducting process of IMCCR running with discontinuous blocked roto…
The ac small-signal conductance of graphene nanoribbons (GNRs) was investigated using non-equilibrium Green's function. Simulation results of ac conductance of GNRs with and without the edge effect are presented. The edge effect and the influence of a slight change in width have great impacts on the ac conductance of…
On-site generated fluorine meets the sustainability requirements for the future of CVD thin-film process chamber cleaning. Rigorous industry safety standards are maintained, GWP and total carbon footprint impacts are greatly reduced, and significant process improvements are available.
Samples with 3 layers of ZnS were prepared on glass substrate by the Sol Gel method. The annealing parameters were varied as follows: each of the 3 constituent layers of sample 1 was annealed at 400 °C for 12 hrs. For sample 2, the 1rst and 2nd layers were annealed at 300 °C for 2hrs each and the 3rd one at 400 °C for…
The starting torque of the line-starting synchronous permanent magnet machines has two components, namely, the driving induction torque and the braking magnet torque. The synchronous PM motor can reach the speed of rotation close by synchronous ones if the asynchronous electromagnetic torque will be greater than the b…
Traditional magnetic circuit methods conclude that slot magnetic conductivity harmonics modulates main magnetic field in air gap to form additional magnetic field, which generates induced potentials in damper winding. However, slot magnetic conductivity harmonics and additional magnetic field can not be accurately cal…
Conditions for the synthesis of the SnO2-Au 0 -(H3PW12O40) y ·nH2O nanocomposite layers by the method of ionic epitaxy were determined for the first time. The layers we investigated by the method of scanning electron microscopy, energy dispersion microanalysis, UV and IR Fourier transmission spectroscopy. On the basis…
The role of reliability prediction during the design stage of a system is worldwide recognized. Simulation tools and proper experimental approaches are usually applied to get reliability properties. In this paper, an experimental method relying on the use the dynamic stress-strength approach is presented and applied o…
Sub-surface imaging system using a solid immersion lens (SIL) is introduced. Aberration caused by cover layer of blue ray disk is minimized with truncated SIL and diffractive optical element (DOE). Sub-surface imaging simulation is achieved by using rigorous coupled wave technique, partial coherence and vector diffrac…
In practical application of active power filter, to avoid damage to power switching devices, a few seconds of dead-time must be inserted in the switching signals to prevent a short circuit. This will cause the deviation of the output voltage waveform, such as the decrease of the fundamental wave, increase of the harmo…
