Based on camouflage performance of military tents, camouflage pigments with four colors are chosen. In order to obtain the good camouflage effect, the digital camouflage pattern is designed as well as based on basic features including main colors and texture of the target background. The camouflage pattern is printed on tent cloths with the pigments using rotary screen printing. The tent made from the tent cloth is located in the typical target background. Finally the camouflage effect of the tent is evaluated. The experimental result shows that, the digital camouflage tent is much easier to blend with the natural background, and achieves a good effect of the optical camouflage.

This paper presents a new method which can generate a digital camouflage pattern based on the background image of a target. It quantizes the background color, and extracts the main color, followed that determines the size of a mosaic block. By filling the blocks with the main color, the digital disruptive pattern is generated. In order to test the camouflage effect, the designed pattern is printed on the tent cloth, and the tent is placed in the actual background. The experimental result shows that, the digital camouflage is easier to blend with the natural background than the traditional camouflage, and achieves a good effect of the optical camouflage.

Fresh maintenance is the main problem existing in the storage of vegetables and fruits on ship. This paper introduced a new technology for vegetables and fruits storage: air discharge. According to the experimental result, air discharge treatment had good effect on the storage. It could reduce the wastage of total soluble solids and titratable acid during the storage. And, it could also reduce percentage of threshing. Air discharge treatment on grape storage appearance had obvious good effect. Air discharge preservation technology can effectively extend the storage time of fruits and vegetables. Improper air discharge can also cause damage to plasmalemma of fruits and vegetables. Various air discharge products concentration must be in safe range. This preservation technology needed to further research for applying on ship.

Aim at some problem in fault diagnose: the characteristic frequency depends on the speed, the spectrum is complex , which are easy to diagnose error when in the variable conditions, and it is often difficult to identify the fault positioning in the frequency domain. the paper puts forward a new method: Variable condition bearing fault diagnosis basing on time-domain and artificial intelligence , not depend on speed and frequency domain. This method use vibration signal, calculates the kurtosis, skewness, rms etc 12 time-domain value, then these character vectors are sent to the neural network classifier to complete fault type pattern recognition, Finally, the same faults are sent to the next neural network for fault positioning and damage extent identification. The experimental result showed that using this method can obtain very good effect.

The present study deals with the extraction of eco-friendly natural dye from pomegranate peel through the pre-mordanting method and its application on Tencel fabric. The investigation was made for the evaluation of the best extraction processes (solvent, ultrasonic and aqueous) with the use of three mordants (stannous chloride, ferrous sulfate and alum) and to compare the effect of different color shades and fastness properties. The experimental result indicated that solvent extraction method delivered better effects on Tencel fabric as compared to ultrasonic and aqueous (solvent[Formula: see text][Formula: see text][Formula: see text]ultrasonic[Formula: see text][Formula: see text][Formula: see text]aqueous). It was due to the extraction of excessive and pure pomegranate peel dye in 100 min time. Furthermore, the fabric samples dyed using mordants have a good effect in color shade. However, amongst all, mordant stannous chloride has an efficient color shade in all extraction methods (stannous chloride[Formula: see text][Formula: see text][Formula: see text]ferrous sulfate[Formula: see text][Formula: see text][Formula: see text]alum[Formula: see text][Formula: see text][Formula: see text]no mordant). Dyed Tencel fabric has excellent washing (4–5), light (5–6), rubbing (4–5) and perspiration (4–5) fastness properties with and without mordants in all extraction methods. FTIR results revealed that the structure of Tencel fabric remained unchanged after dyeing through different extraction methods with pomegranate extract. The overall outcome implied that solvent extraction process with mordant stannous chloride delivered the best effects.

Adding microelements Ag In Ga and Sb into Sn-20Bi solder, the changes of melting properties and microstructures of the solder were observed. The experimental result showed that when the content of Ag was 0.7% (wt%), In was 0.1% , Ga was 0.5% and Sb was 0.5%, the melting points of the solder reduced to the bottom and the segregation of Bi obviously decreased. Sb was not suitable to add solely but when it was added together with Ag In and Ga, it can produce a good effect on reinforcement of solid solution, furthermore it can restrain the phase change of Sn. The Sn-Bi-X solder with the best compositions of Ag In Ga and Sb has a near melting point to Sn-37Pb. The solder is close to practicality without segregation of Bi.

In order to solve the problem of the photo response non-uniformity (PRNU) for High Dynamic Range (HDR) video system, this paper discusses the causes of the problem and the common solution, and then proposed a new non-uniformity correction approach based on the reference source for HDR video system. This approach use high-pass filter to calibration image in Frequency domain to get the correction matrix of one level light conditions at first. And then performs an inverse Fourier transform to the spatial domain. Finally calculate the difference between the correction matrix and the target image to obtain the corrected results. The experimental result indicates that the approach has good effect on dealing with non-uniformity of the HDR images and the definition has been greatly improved.

As the core of digital elevation model, interpolation methods have been run through the each link, such as production, quality control, accuracy assessment, analytical applications and etc. The local radial basis function interpolation method based on spatial relationship of natural neighbor was proposed in this paper. The interpolation reference points were chosen by the Delaunay Triangulation. The first-order and second-order neighboring of interpolation points as the interpolation reference points were used to construct local radial basis function. This method was applied to the construction of digital elevation model, and the correspondent errors were analyzed. Experimental result shows that the method has a good effect on the construction of different landform.

In order to measure the concentration of arsenic atoms in nanometer regions of arsenic doped silicon, the HOLZ analysis is carried out underthe exact [011] zone axis observation. In previous papers, it is revealed that the position of two bright lines in the outer SOLZ structures on the[011] zone axis is little influenced by the crystal thickness and the background intensity caused by inelastic scattering electrons, but is sensitive to the concentration of As atoms substitutbnal for Siatomic site.As the result, it becomes possible to determine the concentration of electrically activated As atoms in silicon within an observed area by means of the simple fitting between experimental result and dynamical simulatioan. In the present work, in order to investigate the distribution of electrically activated As in silicon, the outer HOLZ analysis is applied using a nanometer sized probe of TEM equipped with a FEG.Czodiralsld-gown<100>orientated p-type Si wafers with a resistivity of 10 Ώ cm are used for the experiments.TheAs+ implantation is performed at a dose of 5.0X1015cm-2at 25keV.

The aim of the study was to explore the basic features of self-schema in persons with schizophrenia. Thirty two schizophrenic patients and 32 normal controls were asked to select personality trait words from a check-list that described themselves, themselves as they were five years ago, and what most people are like. Compared with the control group, participants from the experimental group chose significantly more adjectives that were common to descriptions of self and others, and significantly less that were common to self and past-self descriptions. These results suggest that schizophrenic patients experience their personality as changing over time much more than do healthy subjects. Moreover, their self-representation seems to be less differentiated from others-representation and less clearly defined than in normal subjects.
