The purpose of the mainstream of industrial design is to make products to better serve humanity, humancentered design on product safety, ease of use, texture, color planning. However, the design mentioned here runs counter to the mainstream design, mainly in the senses, the use of, and perhaps this design is certainly not practical, but as an active artistic way of thinking may be able to inspire more imagination and creativity. This article is not opposed to the mainstream of industrial design, also can not be considered reflection, is just another angle to explore.

The mainstream of development in knowledge discovery is researching on new high-performance and highscalability mining algorithm. In fact, the research of process model and inner mechanism is more important, which have got enough attention. This paper proposed a new independent knowledge discovery system framework, which combines those three elements: algorithm, model and mechanism. In essence, it derives the systematic method from the general algorithms. Experimental results and researches show that this research can resolve some realistic problems such as timely knowledge databases maintaining and so on;by exposing the essence, regularity and complexity of KD, it would react on the mainstream, and become one available route of constituting the KD theory system..

We propose a novel technique to our knowledge to estimate the beat spectrum linewidth of a free-running heterodyning scheme using an optical discriminator. Utilizing a dense wavelength division multiplexing (DWDM) filter as an optical discriminator, the phase modulation (PM) to intensity modulation (IM) conversion is achieved. Thus converted phase noise of the laser into RIN (relative intensity noise). We establish a relationship between the converted RIN and the beat spectrum linewidth. The proposed concept on beat spectrum linewidth estimation is demonstrated and compared with direct beat spectrum measurement. We show that our proposed technique estimates the beat linewidth more accurately for a free-running heterodyning scheme.

Contrary to the distillation towers, much research has not been fulfilled on dynamic treatment of absorption towers. Studying on dynamic treatment of absorption towers comes back to half a century ago. In order to fulfill such a thing, dynamic and static modeling of sweetening sour gas, by using computational software (MATLAB) has been studied in a tray tower. In the present study, modeling has been written for static condition and the amount of CO2 mole fraction changes on each tray was *** change across the tower was determined by writing energy balance on each tray. The result is conformed to industrial results and the used solvent is 45% MDEA. Although, in comparison with filled towers, tray towers modeling has been less considered because of hydraulic problems and diversity in types of trays, their modeling is so important, because of their widespread usage in industrial conditions. In order to create dynamic simulation, sudden change has been made on the volumetric flow rate of inflow liquid solvent and the way of mole fraction changes on each tray and the exact time to get a stable mode has been surveyed by fixing the number of trays.

A Tunable optoelectronic oscillator (OEO) implemented employing a high-Q spectrum sliced photonic microwave transversal filter without using any electronic microwave filters is proposed and experimentally demonstrated for the first time to our knowledge. The high-Q photonic microwave transversal filter is implemented using a sliced broadband optical source and a dispersive element, to perform frequency-tunable microwave frequency selection. The central frequency of the microwave filter is a function of the wavelength spacing of the sliced optical source and the chromatic dispersion of the dispersive element, therefore, the oscillation frequency can be tuned by changing the channel spacing or the chromatic dispersion of the dispersive element. A theoretical analysis is provided, which is verified by a proof-of-concept experiment. The phase noise performance and the frequency tunability are both experimentally investigated.

We developed a new concept of water solar collector integrated into a drainpipe. This collector is made of several serial modules. The drainpipe keeps its water evacuation func- tion. After a brief presentation of the energy situation in France, the new concept of solar collector is described;the ex- periment, the collected data and the first experimental results are presented and discussed. Numerical calculations are per- formed in Matlab environment, using a finite difference model and an electrical analogy. A second approach using a thermal modeling by Comsol software is also presented.

In order to understand the fluid distribution, the square ECM machining gap flow field mathematical model has been built. It is based on the current flow field theory of ECM;and the machining gap of ECM the square hole is taken as the research subject. COMSOL software and computational fluid dynamics(CFD) have been applied. Under the condition of the same inlet flow velocity and outlet pressure, flow field numerical simulations of the machining gap channels have been carried on towards three different shaped cathodes. In the end the influence of the electrolyte flow velocity and the pressure towards the fluid distribution is summarized.
