Emotional Expression and Artistic Reconstruction in Musical Performance

The emotional expression brought by music is the self-realization and artistic reconstruction of the art of music in performance.From the perspective of the development of musical performance,artistic reconstruction is an important means of expression which does not only explores the emotional connotation of music but also endows music with stronger vitality through the performers'understanding and imagination,presenting them to the audience in a more three-dimensional way and stirring up deep resonance.Performers can also gradually develop their own style of performance.How to better integrate the interaction between the two is an important proposition in exploring musical performance.This paper focuses on the relationship between emotional expression and artistic reconstruction in addition to elaborating the important role of the two in musical performance to provide a useful reference for music creators and performers.

Tropospheric Wet Refractivity Tomography Based on the BeiDou Satellite System

This paper presents a novel approach for assessing the precision of the wet refractivity field using BDS （BeiDou navigation satellite system） simulations only,GPS,and BDS＋GPS for the Shenzhen and Hongkong GNSS network.The simulations are carried out by adding artificial noise to a real observation dataset.Instead of using the δ and σ parameters computed from slant wet delay,as in previous studies,we employ the Bias and RMS parameters,computed from the tomography results of total voxels,in order to obtain a more direct and comprehensive evaluation of the precision of the refractivity field determination.The results show that：（1） the precision of tropospheric wet refractivity estimated using BDS alone （only 9 satellites used） is basically comparable to that of GPS; （2） BDS＋GPS （as of current operation） may not be able to significantly improve the data＇s spatial density for the application of refractivity tomography; and （3） any slight increase in the precision of refractivity tomography,particularly in the lower atmosphere,bears great significance for any applications dependent on the Chinese operational meteorological service.

3D Reconstruction Technique for Tomographic PIV

Tomographic particle image velocimetry(Tomo-PIV) is a state-of-the-art experimental technique based on a method of optical tomography to achieve the three-dimensional(3D) reconstruction for threedimensional three-component(3D-3C) flow velocity measurements. 3D reconstruction for Tomo-PIV is carried out herein. Meanwhile, a 3D simplified tomographic reconstruction model reduced from a 3D volume light intensity field with 2D projection images into a 2D Tomo-slice plane with 1D projecting lines, i.e., simplifying this 3D reconstruction into a problem of 2D Tomo-slice plane reconstruction, is applied thereafter. Two kinds of the most well-known algebraic reconstruction techniques, algebraic reconstruction technique(ART) and multiple algebraic reconstruction technique(MART), are compared as well. The principles of the two reconstruction algorithms are discussed in detail, which has been performed by a series of simulation images, yielding the corresponding reconstruction images that show different features between the ART and MART algorithm, and then their advantages and disadvantages are discussed. Further discussions are made for the standard particle image reconstruction when the background noise of the pre-initial particle image has been removed. Results show that the particle image reconstruction has been greatly improved. The MART algorithm is much better than the ART. Furthermore, the computational analyses of two parameters(the particle density and the number of cameras), are performed to study their effects on the reconstruction. Lastly, the 3D volume particle field is reconstructed by using the improved algorithm based on the simplified 3D tomographic reconstruction model, which proves that the algorithm simplification is feasible and it can be applied to the reconstruction of 3D volume particle field in a Tomo-PIV system.

Reconstruction study of the modem graphic design during the development process

As the major component of the art of visual communication, modern graphic design art has gone from an industrialized society to the information society. The Chinese art of graphic design is much affected by eastern and western cultural trends and artistic styles in concept, function and in the form of semantic and performance. Under the trend of the diversified development of the modern design, new concepts intervened in our lifestyle, in the guided thinking and emotional expression, we find that laws used in the graphic design are gradually being broken, inherent symbol phenomenon is deconstrncted, and people try to find the rational visual space in the mileage crossing the centuries.

Discussion about contemporary Chinese cultural criticism and mass culture

Contemporary Chinese cultural criticism is facing traditional three factors. That are： literary criticism, belletristic criticism and Chinese-style criticism; contemporary transformation from western cultural criticism and consciousness of problems in contemporary Chinese culture together form a problem domain of cultural criticism; during the 30 years, literary discipline knowledge has evolved from the aesthetic to the culture and the weakening and missing of beauty and poetry become a weakness of cultural criticism. Concerning about the study of repression mechanism for appreciation as well as strengthening the aesthetic nature is the proper attitude literary researcher should have while intervening cultural criticism.

Performance Improvements in Temperature Reconstructions of 2-D Tunable Diode Laser Absorption Spectroscopy(TDLAS)

Performance improvement was attained in data reconstructions of 2-dimensional tunable diode laser absorption spectroscopy(TDLAS). Multiplicative Algebraic Reconstruction Technique(MART) algorithm was adopted for data reconstruction. The data obtained in an experiment for the measurement of temperature and concentration fields of gas flows were used. The measurement theory is based upon the Beer-Lambert law, and the measurement system consists of a tunable laser, collimators, detectors, and an analyzer. Methane was used as a fuel for combustion with air in the Bunsen-type burner. The data used for the reconstruction are from the optical signals of 8-laser beams passed on a cross-section of the methane flame. The performances of MART algorithm in data reconstruction were validated and compared with those obtained by Algebraic Reconstruction Technique(ART) algorithm.
