Abstract

FOG is a new type of angular velocity transducer; it is widely used in aviation, aerospace, marine and other fields. During FOG R & D, the test work costs long time, there are many test data in FOG life cycle, including structured data and unstructured data. This paper analyzed the FOG R & D process, and classified the test data. The paper also analyzed the test data management requirements and pointed out the main problems in the test data management. Based on this, test data management methods and test data management system architecture are given in this paper. Finally, a test data management system with B / S structure is developed. DOI: http://dx.doi.org/10.11591/telkomnika.v11i5.2468

Abstract

The carbon emissionshas attracts great concerns in engineering technology researches. The decomposition analysis technology has been popular in the study on influencing factors of industrial carbon emissions(ICE). The change of industries’s CO2 emissions from the three main industries in China over the period 1980-2011 based on the logarithmic mean divisia index (LMDI) method has been carried out. The research indicated that economic activity effect was the main influence factor for ICE increase in China over the entire period; the decline in energy intensity and the adjustment of energy and change in the CO2 emission coefficient were major determinants for reduction of ICE. Meanwhile, we found that China had made a significant contribution to reducing global CO2 emissions by decreasing its energy intensity. Based on the fore study, the mechanism of CO2 emission changes has been analyzed and the pressure-driven environment protection model has been put forward. http://dx.doi.org/10.11591/telkomnika.v11i5.2484

Abstract

A virtual environment of airport’s power supply is very useful for anti-accident training. In this paper, an effective method of anti-accident training for airport’s power supply based on Delta3D VR engine was proposed. The architecture of airport’s power supply training system was introduced. The electric closet’s operating simulation was accomplished based on the device’s operation logic. The model of fault and relay protection was designed according to electrical characteristics. A finite automaton model of diesel engine was presented based on operating conditions for virtual operation. Finally, a VR based airport’s power supply system was built and verified in worker’s training. DOI: http://dx.doi.org/10.11591/telkomnika.v11i5.2501

Abstract

Fuel cell powered systems have low voltage and high current output characteristics. Therefore, the output voltage of the fuel cell must be stepped up by DC-DC converter. In this paper an integrated mathematical model for proton exchange membrane fuel cell power system with DC-DC converter is described by analyzing the working mechanism of the proton exchange membrane fuel cell and the boost DC-DC converter. Fuzzy sliding mode control scheme is proposed to realize stable output voltage under different loads. Simulation operations are carried out and results are compared with fuzzy control and sliding mode control. It is shown that the use of the proposed fuzzy sliding mode controller can achieve good control effect. DOI: http://dx.doi.org/10.11591/telkomnika.v11i5.2553

Abstract

Both of berth allocation and quay crane assignment are one of the most complex parts in container terminal operations, which significantly affect the operational efficiency, energy consumption and operational cost of the entire container terminal. Therefore, it is necessary to develop an efficient strategy for integrated berth allocation and quay crane assignment (BACP) from the perspective of knowledge, which aims at energy-saving and improving operational efficiency. In this paper, knowledge acquisition for BACP is initially conducted. And then, knowledge sorting process for BACP, including taxonomic tree generation and organization of acquired knowledge, is performed. After that, rules for BACP are extracted using the IF and THEN clause. Furthermore, a knowledge reasoning mechanism is designed. Finally, numerical experiments are used to illustrate the proposed knowledge-based system and verify the effectiveness and reliability. DOI: http://dx.doi.org/10.11591/telkomnika.v11i5.2452

Abstract

Restroration of worn parts is a key technique in remanufacturing engineering. It is also a popular research topic in the domain of sustainable manufacturing. To tackle the difficult problem of obtaining a reference model for repair of worn parts, this paper proposed a novel approach to regenerate the vertices over the worn cavity. After a brief description of the repair process, this paper focuses on the optimal energy model establishment. Based on the energy model the vertices of the worn cavity can be regenerated. Error calculation of the vertices recreated to the original model is proposed to search the shortest distance. These algorithms proposed were implemented in the repair system through Visual C++6.0. Several examples of worn parts are presented to illustrate the feasibility of the method. The testing result shows that the vertex regenerated through the optimal energy model can satisfy the requirement of accurate geometry regeneration for repair of worn parts. Finally, conclusions are drawn and further research work is discussed. DOI: http://dx.doi.org/10.11591/telkomnika.v11i5.2479

Abstract

Micromachined gyroscope always contains two groups of capacitors, one is the driving capacitor, which is used to drive the micromachined gyroscope, to make sure the gyroscope could oscillate along the driving direction. The other is so called the sensing capacitor, which used to detect the displacement along the sensing direction, in order to detect the input angle velocity. Since there are some imperfections during the machining process, the static value of the driving capacitor and sensing capacitor always have some variations. These variations would cause some bad effects in the integrated circuit. In this paper, the variations of driving capacitor and sensing capacitor are analyzed based on the principle of integrated circuit. It is shown that the effect caused by driving capacitor variation would be cancelled in the signal processing, but the driving capacitor variation could cause a DC error signal at the output node of the first LPF in the integrated circuit. This DC error would distort the desired signal at the output node of the amplitude amplifier. So that a DC error self-correcting circuit is designed, both the simulation results and the testing results show that DC error could be self-corrected by this additional circuit. DOI: http://dx.doi.org/10.11591/telkomnika.v11i5.2513
