Relationships between Handwriting Components and Underlying Perceptual-Motor Functions among Students during Copying and Dictation Tasks
Authors: Parush Shula , Lifshitz Nirit , Yochman Aviva , Weintraub Naomi
Published: January 2010

The purpose of this study was to examine the interrelations between legibility of handwriting, atomistic factors, handwriting speed, and perceptual-motor body functions. The authors aimed to determine the contribution of these factors in predicting students' handwriting performance during copying and dictation and to assess performance differences under both of these writing conditions. The handwriting performance of 35 third graders with writing difficulties and 35 control subjects was assessed during copying and dictation. The control group performed significantly better on all measures during both copying and dictation. Only overall legibility predicted handwriting performance during copying, whereas both speed and overall legibility predicted handwriting performance during dictation. Only spatial organization significantly predicted overall legibility for both groups and conditions. The findings suggest that handwriting speed and overall legibility are separate constructs and that different components underlie writing during copying and dictation. These results have clinical implications for handwriting evaluation and intervention.

A Forecast Model of Agricultural and Livestock Products Price
Authors: Zhang Wen Sheng , Chen Hong Fu , Wang Ming Sheng
Published: January 2010

The frequent and excessive fluctuation of agricultural and livestock products price is not
only harmful to residents’ living, but also affects CPI (Consumer Price Index) values, and even leads
to social crisis, which influences social stability. Therefore it is important to forecast the price of
agriculture and livestock products. As a result, we made a research on the factors affecting
agricultural and livestock products price, established a forecasted model of agricultural and livestock
products price, and developed its early-warning system which is suitable to China. Considering the
direct relationship between the price and the output, multiple linear regression method was adopted to
study this problem. The model is composed of three sub-models. This paper puts forward the concept
of price equilibrium coefficient C0, which describes the degree to which people accepting the
forecasted price. With the establishment of the standard for the influence of price fluctuation, the
influence of price fluctuation is measured. Each range of the C0 value corresponds with a specific
result, which may informs the government with the danger of price fluctuation. As a result, the model
can early-warn the price rising caused by crop reduction due to sudden natural disaster, which may
induce social turmoil and crisis. If the forecasted price rises heavily, the government should take
measures to avoid crisis. This paper offers the method to control future price. Finally, a forecasted
model of pork price is calculated with simulated data. The forecasted result is in good agreement with
actual situation.

Authors: Wei Xiu Ting , Liu Jing Cheng , Du Qiang
Published: January 2010

In this paper, two modeling methods, the forming method and the generating method, for hypoid gears with two kinds of transmission ratio are discussed by simulating the actual machining process. In the generating modeling method, the tooth profile of the gear is generated by boolean algorithm step by step after creating the models of the gear blank and the cutter and then rotating around their own axis by certain degrees until the cutter is outside the gear blank completely. In contrast with the generating modeling method, the tooth profile is formed by carrying out the boolean algorithm for one time after creating the models of the gear blank and cutter seperately in the forming modeling method. Then using feature instance, all the teeth are created both in the generating modeling method and in the forming modeling method. Using the two modeling methods given in this paper, the modeling process can be shortened and the modeling precision can be improved.

Multi-hop cooperative MIMO network that consists of multiple nodes each equipped with single antenna is introduced and investigated. Optimal power allocation scheme with selective decode-and-forward (SDF) cooperative strategy is formulated and solved by means of optimization method with the purpose of minimization of system’s symbol error rate (SER), which are derived and analyzed with numerical results presented. Distributed space-time block Code (DSTBC) in multi-hop cooperative MIMO is analyzed and compared with optimal power allocation scheme with SDF strategy. Simulation results reveal that, cooperative diversity could be achieved with optimal power allocation. Optimum power allocation scheme depends on the relay’s position and channel quality between source to relay and relay to destination. Novel performance comparison between optimal power allocation and DSTBC are researched and presented. Simulation results confirm our theoretical analysis, which indicates that multi-node DSTBC outperforms optimal power allocation scheme due to the fact that cooperative diversity gain and coded gain could be obtained simultaneously for DSTBC in multi-hop cooperative MIMO network.

In order to implement the spatial Inverse Distance Weighting (IDW) interpolation in parallel, we use the quadtree approach to decompose the spatial domain and execute the IDW interpolation on these quads through the parametric tasks on Windows HPC platform. The whole implementation includes the executables of QuadDC, IDW, output gathering and data visualization which should be run serially. Compared with the traditional method to integrate each executable manually, the Job Manager of Windows HPC utilizes multi-task job to serialize all the executables as a workflow. The experiments test two cases of IDW0 and IDW6 with different domain clustering regions, and show that our implementation improves the functionality integration and efficiency of the spatial IDW interpolation.

Published: January 2010

A novel algorithm is presented to acquire accurate human contour. For current algorithms extracting contour with multi-pixels width, it is difficulty in obtaining accurate distance between centroid and any point on human contour for gait recognition. For connective human contour, we use candidate regions and vectors to calculate and compare the angles of adjoining vectors, so that we get point set of human contour and describe human contour of single-pixel width. For disjoint contour, image pre-processing is implemented to fuse disjoint silhouettes with their centroids. Subsequently, we go on performing the algorithm of complete contour to get accurate contour. This algorithm solves the problem that any point on human contour locates accurately. It takes the advantages in image processing of human silhouette, particularly in accurate extraction of human contour for gait or posture recognition.

Authors: Zhou Xuan Wu
Published: January 2010

As a typical fast public key cryptosystem, HCC (Hyper-elliptic Curves Cryptosystem) provides efficient asymmetric algorithms for cryptography schemes. In the paper, we presented an improved authenticated encryption scheme based on HCC as a prototype of signcryption scheme. In the scheme, data encryption and signature generation can be achieved in a single formula and signature verifying protocol is also the decryption algorithm. Therefore, the scheme achieves secret message transmission and authentication simultaneously in one protocol. The scheme renders effective secrecy protection for message receiver; the attack on the authenticated signature and random parameters via the cipher-text is computationally infeasible. The designing strategy of message recovery signature reinforces the security and reliability of authenticated encryption and greatly improves its efficiency for software and hardware application. As a generalization of the authenticated encryption scheme, we presented a signcryption scheme based on HCC. The scheme makes full use of the superiority of fast asymmetric cryptosystem and effectively improves the application efficiency of signcryption for integrated environment.

Authors: Li Yan Jie , Piao Lin Hua
Published: January 2010

The sensitive mechanism of the airflow tilt sensor was analyzed by finite element method. The streamfield caused by heat source, when the three-dimensional enclosure inclining, has been obtained by a series of procedure,such as model building, meshing, loads applying and equation solving. In the process, ANSYS-FLOTRAN CFD program is employed. In horizontal status, the velocity of gas flow is equal at the two thermistor wires; therefore the current of both wires are also equal and the output of the bridge circuit is zero. In tilting status, the velocity difference of gas flow at the two thermistor wires will change with the tilt angle; therefore lead to changing of the current difference of both wires, the bridge outputs avoltage signal corresponding to the tilt angle. This calculation method provides a new approach to optimization of airflow tilt sensors.

Authors: Zhang Gui Mei , Chu Jun , Miao Jun
Published: January 2010

Existing methods for recognizing polygons can be improved. A new concept “homograph” and then a new method for recognizing polygons based on the principle of homograph are proposed. First six topological characteristics and geometrical characteristics are introduced that are invariant to describe polygon under affine transformation. Then, the new concept of homograph is defined in terms of six topological characteristics and geometrical characteristics. Based on of this definition, a new algorithm is proposed for recognizing that two polygons are homograph. The topological structure is introduced to analyze homograph qualitatively, the algorithm is insensitive to noises; and the geometrical structure is introduced to analyze homograph quantitatively, thus the algorithms can show tiny differences between polygons. It can not only recognize objects with different shape but also distinguish between objects with the same shape but with different sizes and scales. Comparing with other recognition algorithms, the algorithm presented showed apparent improvement. The effectiveness of the algorithm is demonstrated by experiments.

Robust Image Corner Detection Using Curvature Product in Direct Curvature Scale Space
Authors: Zhong Bao Jiang , Li Chang
Published: January 2010

In this paper we propose an image corner detector based on the direct curvature scale space (DCSS) technique, referred to as the curvature product DCSS (CP-DCSS) corner detector. After the contours of interested objects are extracted from a real-world image, their curvature functions are respectively convolved with the Gaussian function as its standard deviation gradually increases. By measuring the product of the curvature values computed at several given scales, true corners on the contours can be easily detected since false or insignificant corners have been effectively suppressed. A point is declared as a corner when the absolute value of the curvature product exceeds a given threshold and is a local maximum at the mentioned point. CP-DCSS combines the advantages of two recently proposed corner detectors, namely, the DCSS corner detector and the multi-scale curvature product (MSCP) corner detector. Compared to DCSS, CP-DCSS omits a parsing process of the DCSS map, and hence it has a simpler structure. Compared to MSCP, CP-DCSS works equally well, however, at less computational cost.

The paper also gives the results based on the traditional methods including GARCH, EGARCH, GJR and so on. The comparison is obvious and HHT is new good choice. The data is from China stock market up to 10/12/2009.

Monthly electric energy demand forecasting plays an important role for the running of power system. China has two tow calendars and they works at the same time. Holidays designed by the lunar calendar affect the regularity of monthly electric load recorded only by the Gregorian one. The normal fuzzy transform is advanced here to quantitatively describe the impact of the Spring Festival and further divided the influence into Jan. and Feb. After excluding the influence, the amended historical data are adopted to training RBF neural network. Experiment results show that because the regularity of raw data is improved, the generalization ability and forecasting precise of RBF neural network are improved.

Published: January 2010

The linear friction welding (LFW) behavior of Ti-6Al-4V, a commercial α + β titanium alloy, was investigated using oscillation frequencies ranging from 30-70 Hz and axial pressures from 50-110 MPa. LFW samples were examined using electron backscattered diffraction (EBSD) to relate the texture to the welding parameters and to the estimated strain and strain rate. Characterization of the welds included analysis of the microstructure of the weld and of the thermomechanically affected zones (TMAZ) in relation to the parent material.

Advanced High Strength Steels (AHSS) are key materials in the conception of car body structures, permitting to reduce their weight while increasing their behavior in crash conditions. Nevertheless, the weldability of AHSS presents some particular aspects, in that complex failure types involving partial or full interfacial failure can be encountered more often than with conventional mild steels during destructive testing, despite high spot weld strength levels.
This paper aims at characterizing the behavior of different AHSS spot welds under two quasi-static loading conditions, tensile shear and cross tension, often used in the automotive industry for the determination of their weldability.
Interrupted cross tension and tensile shear tests were performed and spot welds failure was investigated with optical micrographs, SEM fractography and 3D-tomography in order to follow the three-dimensional crack paths due to the complex loading modes. A limited number of failure zones and damage mechanisms could be distinguished for all steel grades investigated. Moreover, numerical simulation of the tests was used to better understand the stress state in the weld and the influence of geometrical features such as weld size on the occurrence of the different failure types.

Cold spraying is a novel coating method, by which many composites have been successfully sprayed. The objective of this study was to thoroughly characterize the microstructure of copper as well as copper/alumina composite coatings obtained using this technique. Composite coatings which differed to the percentage of Al2O3 in the initial powder blend as well as the Al2O3 particle size were studied. Coatings presented Ra of the order of 6-8 μm, with the copper coating having the highest value. Using optical microscopy the deformation of the copper particles of the cross sections was evident. Thickness ranged from 170 to 450 μm for the different coatings. The surfaces and the cross sections of the coatings were studied by means of scanning electron microscopy. Craters and Al2O3 particles that were embedded in the copper particles were observed. The XRD analysis of the powders and the respective coatings presented no differences.

Published: January 2010

The mechanical characteristics of dentine have been investigated on local scale by micro-hardness and instrumented indentation tests. FIMEC, an indentation technique employing a cylindrical punch, permitted measurements of elastic modulus, yield stress, stress-relaxation and creep. The punch diameter (Φ = 0.5 mm) is much larger than the tubule size thus data are not so largely scattered as in micro- and nano-indentation tests but, at the same time, is small enough to guarantee a good resolution in mapping the mechanical properties in different tooth positions. The results are in agreement with literature data obtained by means of various experimental techniques.
Furthermore, through tests of mechanical spectroscopy carried out on bar-shaped samples (13 mm x 4 mm x 0.8 mm) the dynamic modulus and the damping factor Q-1 have been measured.

Published: January 2010

Friction Stir Processing (FSP) has potential for locally enhancing the properties of Al-Si alloy castings, for demanding applications within the automotive industry, by greatly refining the second phase particle size. In the present study, the homogeneity of particle refinement and second phase spatial distribution within the process zone, as well as the relationship to the processing parameters, were investigated in a gravity die cast Al-Si LM24/A380 alloy, subjected to a range of FSP conditions. Detailed image analysis and the dirichlet tessellation method were used to quantify particle clustering. ‘Stop-action’ experiments were also used to study the process of particle break up, by following the behaviour through the deformation zone surrounding the tool.

Published: January 2010

AgCl@polypyrrole(PPy) nanocomposites were synthesized through in situ chemical oxidation polymerization by using poly(vinylpyrrolidane) (PVP) as dispersant, and some Au colloid were prepared by using KBH4 as reductant and sodium citrate as stabilizer, then the Au nanoparticles-AgCl@PPy hybrid material was formed by physical chemical reaction. Fourier transform infrared spectrometer (FTIR) and electron dispersive spectrometer (EDS) data suggested that the hybrid material were composed of Au, AgCl and PPy. An amperometric glucose biosensor was fabricated by adsorbing glucose oxidase (GOx) to an Au nanoparticles-AgCl@PPy hybrid material modified platinum electrode. The biosensor exhibited a super highly sensitive response to H2O2.
