Visualization as a problem-solving and knowledge discovery tool has become even more important as we enter the Big Data era. Time is a very important dimensionality and attribute. We call these data that change with time and has time attribute temporal data. The time series data that are arranged in time shaft are this paper's object of study. In the field of science, engineer and economy, a large...
The self-index is a kind of highly compressed, self-contained full-text index. It is designed for indexing plain texts in order to reduce its permanent storage, as well as to enhance searching performance. Apart from being a sequence of characters, usually the text has specific internal structure. The data record, as a basic model of structured data, is therefore employed to represent and organize...
The characteristics of international academic conference is analyzed specifically, the principle and process to design the organization structure and work breakdown structure (WBS) of international academic conference are proposed on the basis of the theory of event management and work breakdown structure in project management. Then the reference organization structure and general WBS of international...
The ultimate goal to valuate the automotive supply chain performance is to carry out the overall optimization of the automotive supply chain. It is the key of supply chain performance evaluation that a set of perfect automotive supply chain performance evaluation index system must be establish. According to the definition of automotive supply chain performance, the automotive Supply Chain Performance...
Crystal-based DPSK and DQPSK demodulators using the principle of polarization beam interference(PBI) is theoretically introduced in this paper, the performance of the DPSK demodulator is also measured. What's more, they are both polarization-independent.
The modified Szabo's wave equation is an effective and new model for the power law frequency-dependent dissipative acoustic wave traveling through the complex lossy medium, in which the positive fractional derivative has first been used. This study makes an attempt to test the influence of tumor sizes on the reflecting line of ultrasound pressure by numerical simulating the CARI technique for breast...
