A software is designed for water quality monitoring in the aquaculture industry. It is mainly for dissolved oxygen soft sensing. Dissolved oxygen is an important dependent factor of water quality and has effect on fish growth. At present, most of the dissolved oxygen sensors are expensive for aquaculture farmers, so they won't use them for real-time detection to perform control and optimal operation...
This paper first introduces the safety rule which standardizes static software testing based on technology of source code analysis and lists a few big problems which can be tested by the technology. These problems can be categorized as memory management, uninitialized variables, null pointer exception, array access violation and exception and buffer overflow. Besides, this paper gives a static test...
Focus on the risk management for the modern weapon equipment development projects, the intuitionistic fuzzy group decision-making ranking process is proposed in this paper to achieve a further risk ranking for the risks with the same risk exponent, making the ranking results more accurate and scientific. In this process, assessments are made on the risks' occurring possibility and the consequences...
To the problem of soft-sensing the component concentrations of sodium aluminate solution, a soft-sensor software was designed and developed based on the mechanism and data-driven model. It included three parts which were control software, monitoring software and model calculation software. Industrial experiments showed that the software was simple to use, real-time, GM, and it was the foundation for...
PCI Express is a high-speed point-to-point transmission bus interface that widely used. but a standard PCI Express system starts to traversal the bus topology after 100ms from the power on and to make sure the equipment that ready to response the configuration request. This becomes a difficult task due to the ever-increasing configuration memory size of each new generation of FPGA, such as the Xilinx...
The failure mode and effects analysis (FMEA) technology is one of the basic methods in the process of designing and analyzing the reliability. In view of the poor development for FMEA analysis tools of the army equipment, a new equipment FMEA software system is designed according to the special function requirements of equipment FMEA software on the basis of the FMEA software development technology...
Embedded technology and people's lives have been closely related, but traditional data acquisition system only responds to particular signals, which is quite limited. A newly-designed idea is proposed in this paper with ARM9 processor as the core components to design a common data acquisition system. We need to use different data acquisition board according to different signals, to form a user-defined...
To ensure the safe evacuating environment in an urban traffic tunnel fire, the performance-based design of smoke control strategy was applied in this paper. A preliminary design of the smoke control strategy was evaluated by using the software FDS. By analyzing the distribution of the temperature and visibility around the fire source, it was found that the preliminary strategy could not satisfy the...
The vibrating screen is the important industrial equipment that is used to sort and clean the granular materials. Screening results of the granular materials is directly affected by working state of vibrating screen. The detecting device that was used to detect working state of vibrating screen was developed with miniaturization, intelligence and high integrated level. Triaxial acceleration sensor...
Application of traditional design methods and finite element analysis method of comparative analysis of modern design, by design and analysis to 1HS-1.2 deep tillage profiling spring, subsoiler make a good job of solving the deep pine uneven surface operations on the quality of sub soiling, subsoiler operation to ensure consistent uniform depth.
In this paper, we provide a new method, named dynamic software evolution method, for component based software evolution and this method is consisted of a collection of algorithms. Each algorithm achieve one software evolution objective, and all theses algorithm is meaningful for software evolution strategy design and better understanding component based software evolution process.
This paper introduces a high speed data acquisition system based on NIOS II, especially focuses on the development process of NIOS II soft-core in data acquisition system. Acquisition data is transferred to computer for displaying and analysising by USB interface. Acquisition rate is 250MSPS, the real-time and low-pass filter is used as well, the acquisition data is stored in the RAM first, then processed...
An advanced learning system architecture with several flexible, mobile and joyful ICT features for the ubiquitous learning is proposed in this research based on experiential learning theory, constructivism learning theory and joyful learning feature. The architecture consists of five hardware key elements and supporting software to form a brand-new ubiquitous learning system. We call the designed...
The research and development of architecture of Virtual Operation Training Domain Application Systems (VOTDAS) can not only unify the system modeling method, but also realize the reusability of software architecture and components to the maximum degree. Aim at the domain application of virtual operation training, the paper brought out reusable framework of VOTDAS and researched on the modeling method...
At present, China is universally short of professional computer room managers and the modern management of the environment seems especially important, which makes studying and developing a stable, advanced, effective and high performance price ratio environmental monitoring system extremely necessary. Combined with the production practice of hydraulic power plants, this paper proposes a brand new...
Compared with the study based on the symmetric information between the enterprisepsilas native and exterior, the paper studies the asymmetric information by data mining of the enterprisepsilas native and exterior information, and then analyzes the relationship between them. At last, the software realization frame work is presented. The data-mining of the enterprisepsilas native information is very...
Total RNA from Goose liver of 16 weeks old was isolated. The 365 bp cDNA segment was amplified by the reverse transcription polymerase chain reaction (RT-PCR). Sequence analysis showed that there is a high similarity between the fragment of cDNA and Sterol regulatory element binding protein-2 (SREBP-2) gene. This segment contains a bHLH motif, basic region and leucine zipper domain. Meanwhile, the...
A balancing model between the structural testing and functional testing is proposed, it is the definition-use testing methods. The testing coverage criterion between full path and full edge is discussed. This method provides a system solution to check software default. This model applied in software testing will improve the software quality.
Component behavior modeling and relativity analysis is a crucial issue for the component-based software maintenance and evolution. There are two prerequisites for each application of maintenance or evolution strategy. The first is modeling the behavior of the evolving component, and the second is determining the components which are behavior related with the evolving one. In this paper we provided...
