This paper presents a statistical analysis of voiced plosives such as b, d, g that occur in 466 Uyghur single-syllable or multi-syllable words in the "Uyghur language acoustical database". The results describe the acoustical features such as the formants, sound intensity, duration, voice onset time (VOT) and the GAP (silence segment) distribution model. The acoustic phonetics are compared to identify the devoiced parametric features of the plosives and the tenuis consonants. The real speech data shows that the plosives have features of tenuis consonants devoiced. The critical acoustical parameters are identified that differentiate the plosives.

It is important significance to build integrity and consistency demand model of Software Project. One of the aims of Aspect-Oriented Requirements Engineering is to address the compos ability and subsequent analysis of crosscutting and non-crosscutting concerns during requirements engineering. Paper document-driven demand for aspect-oriented approach needs analysis process, focus is given to certain modeling process validation strategy is proposed based on ontology model validation concerns related methods, and an example illustrates the proposed method of effectiveness. This evaluation shows that the focus of the revised model satisfies all the constraints defined in the text, and based on the actual needs of text analysis, testing the integrity and consistency of the model to verify the effectiveness and energy cost efficiently of the proposed method. © Sila Science.

Detecting the unused spectrum and sharing it without harmful interference with other users is an important requirement of the Cognitive Radio network to sense spectrum holes. This paper focused on the spectrum sensing models and some kinds of spectrum sensing algorithms and their improved algorithms. And attention is concentrated on the performance compare of the different algorithms. © 2012 Springer-Verlag.

The cognitive radios must have the capability to determine if a signal from a primary transmitter is locally present in a certain spectrum. This paper proposed a cooperation algorithm for spectrum detection based on likelihood ratio for primary users' detection in multi-user's cognitive radio system, this algorithm has especially considered different channels decline with the state of decaying of the route between primary users and a lot of cognitive users, the single node detection adopts the energy law. According to the likelihood ratio law, the mathematical model is set up, and has simplified relevant parameters rationally, has reduced algorithm complexity. © 2012 Springer-Verlag.

With the development of economy, high-rise buildings in medium and small cities quickly developed and what to bring the great challenge and higher requirements for Construction enterprise. Combined with the construction features of the high-rise buildings, in construction management work, strengthening the key of the control is one of the best way to promote quickly at the top of the construction enterprise management level. This paper respectively from the high building construction organization management measures, the construction organization design, dynamic control and the deep foundation pit supporting, the standard lines control and the strength of concrete control analysis and expounds that high-rise building construction of management of the control points. © (2012) Trans Tech Publications, Switzerland.

Tracer experiment to obtain flow longitudinal dispersion coefficient is the most direct and reliable method. In this paper, the existing natural rivers longitudinal dispersion coefficient tracer experimental method for calculating is analyzed comprehensively. Focuses on the method of moments, the principles and applications of regression analysis, calculus optimization methods, and analyzes their advantages and disadvantages. In recent years the calculus optimization method is outstanding, determine river longitudinal dispersion coefficient method was developed and applied to an instance of some of the new tracer experiment. Local conditions should combine with topographic flow characteristics to select the appropriate calculation methods in practical applications. Finally, some problems of the natural rivers longitudinal dispersion coefficient study that need further investigation were put forward. © (2013) Trans Tech Publications, Switzerland.

Green construction is a relative concept, development, become the subject of the relevant departments of the State and enterprises need to seriously consider building green construction to carry out construction work in sustainable development boom. This paper describes the construction enterprise green construction; analysis learned difficult to implement green construction, mainly in four areas, namely the lack of awareness of green construction, current management mechanism is not perfect, irrational development of the construction industry as well as economic benefits can not be is embodied, and for these reasons put forward countermeasures and suggestions to expedite the implementation of green construction in the construction work carried out. © (2013) Trans Tech Publications, Switzerland.

Green construction is a relative concept. For different countries and regions, according to the social economic, technical level, plan specific contents of technical innovation and the corresponding technical, economic indicators, in order to guide the development of the green construction. This paper expounds the connotation of green construction, the necessity of developing green construction, and probes into the construction of green in building engineering construction principle, carry out countermeasures and suggestions about how to put forward and speed up the construction of carrying out green in the construction engineering. © (2013) Trans Tech Publications, Switzerland.
