The technical structure of a composite function block with self thermal insulation is introduced. Block — thermal insulation layer-protective layer trinity is achieved through setting tie bars within the block. The block not only collects multiple functions to one body, such as load-carrying/maintenance, thermal insulation, drainage and exhaust, anti-shedding and anti-crack for surface layer etc. But also it collects both safety and durability to one body. The kind of block has many characteristics such as maintenance-free, strong compound function and so on. The block can greatly avoid quality defects of the wall block building non-structural cracks though structure measures, and has been confirmed by the pilot building.

Semantic Web services (SWS) and business process management (BPM) technologies are gradually applied in many domains like electronic commerce and enterprise application integration, which has unavoidably led to the requirements and concerns for effectively recovering from kinds of failures, especially in complex, untamed and dynamic Web environments. Generally, Exception handling is considered to be one of the most important mechanisms for dealing with exception conditions. However, current business process programming languages for semantic Web services provide almost no support for exception handling, and support platforms are weak in providing reliability and adaptability. In this paper, we present a novel framework for flexible exception handling and fault recovery of semantic business processes based on Semantic Programming Language (SPL). Especially, the framework provides forward recovery support with dynamically discovering and substituting failed services when an exception arises during execution by semantically equivalent or semantically similar Web services.

A CMOS dB-linear Variable Gain Amplifier (VGA) using Curvematching is presented. The CMOS dB-linear VGA provides a variable gain of 59dB while maintaining −3dB bandwidth greater than 86MHz. Curvematching is proposed to obtain the dB-linear gain control characteristics based on a low-distortion source-degenerated differential amplifier structure. Nonideal effects on dB linearity are analyzed and the methods for improvement are suggested. The VGA is designed in a 0.13μm CMOS technology and the post-simulation results demonstrate the good dB linearity, good property of total harmonic distortion and noise figure.

On the basis of analysis on the characteristics of single phase grounding fault occurred in small current neutral grounding system, a fault location method using Learn Vector Quantization Neural Network is put forward. Combined LVQ Neural Network with C-type of traveling wave location method, the purpose of precise location can be achieved. A classical BP (Back-Propagation) Neural Network has been developed to solve the same problem for comparison. The simulation results of ATP-EMTP and MATLAB show that the LVQ Neural Network is quite effective and superior to BP Neural Network in fault location.

After Optimal distribution substation locating, distribution feeder line planning remains the main problem in distribution system planning. Therefore, a MST-based and new GA algorithm for distribution network optimal planning is presented. To reduce computational time and avoid infeasible solution, two new operators are introduced to ensure that all individuals are feasible solution. Meanwhile, an electricity distribution network structure and feeder cross-sectional area selection simultaneous optimization model is adopted to deal with the weight of the minimal-cost system tree. This Combinatorial coding guaranties the validity of solution towards globe optimum. Finally, The method is examined in one real MV distribution network example.
