Aiming at the defects of repeating searching the path, low efficiency and the slow speed of the traditional topology algorithm, proposes a network topology algorithm based on Breadth-First-Search in this paper.Introduces the topology modeling method,and the electric equipment is abstracted into nodes and branches,making the topology process not constrained by the network connection and structure,enhancing universal property of the algorithm.Then introduces the traditional method, and analysises the disadvantages. At the same time,puts forward a new method. Uses node-branch adjacency list in the new method,which improves the topology speed.When the local switch information is changed, can modify the node-branch adjacency list to conduct the local re-topology,so it improves the topology flexibility. Finally, through the example, proves the superiority and practicability of this algorithm.

Due to the diversity of the situation information collected in the battlefield, and the conventional way of plotting runs with low efficiency and slow speed. This paper bring forward a new method of battlefield situation collaborative plotting based on ontology, which improves the integration plotting efficiency by formulating the local ontology construction. And based on the local ontology character constructed, solved the semantic mapping problem in the process of rapid ontology integration with a new similarity calculation algorithm.In the end this paper design a battlefield situation collaborative plotting prototype system based on client-server mode consequently.

For the problems like discreteness, tolerance, non-linear of the parts, acquiring the fault knowledge of analog system in electric equipment is hard. This method realized the process of KA automatization through the combination of PSPICE software and C language and taking command lines as combining site. Using the batch file, the programs will form some topological information and parameter information about the fault states of a circuit system each time. The result of a experiment about an Basic Transistor Amplifier circuit proves its feasibility.

Traditional method of buoy gauge design is rather complicated, so an advanced method by building and solving fluid mechanics equations is proposed in this paper. The curve of the taper pipe inner surface is calculated, according to different buoy gravity and diameter. In order to examine the effect of this improved method, an experiment is carried out. Results show that linear property of the buoy gauge improved by new method is excellent.

Pointing at the low efficiency problem of I/O operations of small files using HDFS application architecture, this article proposes a new method, that is, add disk buffer on DataNode to reduce addressing time of reading small files, and thus reduce reading time, and reduce the stress bringed by frequent NameNode access, so as to optimize the reading efficiency of small files. Experiment results show that the design programme is feasible, and adding disk buffer benefits for increasing efficiency of processing small files applying HDFS.

Traditional method for measuring liquid level of absorption tower in wet flue gas desulfurization (WFGD) system is introduced in this paper, and it's found that measuring accuracy of the method exists in large deviation. A new method is proposed to measure liquid level of absorption tower for this situation. The local test results show that not only measurement result of new method is more close to the actual liquid level than traditional method, but also using new method can save operation cost and ensure the safety, stability, and economic operation of WFGD system.

Flipping a classroom is not only recording classroom lesson into a video and bringing homework into the classroom. It is a whole new method with a lot better result compared to the traditional method. In western countries such as the US, flipping a classroom is already becoming a new method adopted by many different schools and universities. This paper tries to explore the possibility of flipping a classroom for learning foreign language at BINUS University by comparing it with the recent practices and findings in the western countries. After the analysis it can be concluded that this method can be applied at BINUS University but on several conditions such as the improvement of infrastructures, and the teacher’s awareness and understanding to optimize their understanding about flipped learning.

Important biological information is encoded in the topology of biological networks. Comparative analyses of biological networks are proving to be valuable, as they can lead to transfer of knowledge between species and give deeper insights into biological function, disease, and evolution. We introduce a new method that uses the Hungarian algorithm to produce optimal global alignment between two networks using any cost function. We design a cost function based solely on network topology and use it in our network alignment. Our method can be applied to any two networks, not just biological ones, since it is based only on network topology. We use our new method to align protein-protein interaction networks of two eukaryotic species and demonstrate that our alignment exposes large and topologically complex regions of network similarity. At the same time, our alignment is biologically valid, since many of the aligned protein pairs perform the same biological function. From the alignment, we predict function of yet unannotated proteins, many of which we validate in the literature. Also, we apply our method to find topological similarities between metabolic networks of different species and build phylogenetic trees based on our network alignment score. The phylogenetic trees obtained in this way bear a striking resemblance to the ones obtained by sequence alignments. Our method detects topologically similar regions in large networks that are statistically significant. It does this independent of protein sequence or any other information external to network topology.

This paper elaborates a method to realize the single phase full bridge inverter digital controller based on DSP TMS320F28027 and gives the design scheme of both its hardware and its software. In accordance with SPWM duty ratio parameter calculated with DSP algorithm, utilizing the EPWM module on DSP, it finally attains the inverting control from direct current signal to sine wave signal. Compared with traditional method, this new method improves the output waveform effectively and shows stable performance.
