KSORD (keyword search over relational database) techniques allow users to obtain information from databases, which is just like using search engines. However, the advanced techniques only realize exact queries, but not for fuzzy queries. The Rocchio algorithm of learning classification is introduced which is made a little changed to achieve keyword search over relational databases. According to the...
Specific absorption rate (SAR) is an important measure for evaluating cell phones and other electronic devices. The IEEE Standard 1528 does not give a detailed description of simulation parameters to be used in the FDTD method. In this paper, we attempt to fill this gap by providing a detailed description of the FDTD evaluation of the SAR by using the configuration given in IEEE Standard 1528.
In this work, we report the results of a study in which we use the parallel FDTD method running on multiple processor, to simulate a large antenna array with helical elements, which cannot be handled by using a single processor. Both the co- and cross-polarized patterns are calculated. Most of the available FEM or MoM-based codes were found to be inadequate, especially when the dielectric supports,...
On many-core chip designs, short, often-multicast, latency-critical messsages, used extensively in high-level coherence and synchronization protocols, often become the bottleneck of parallel performance scaling. This paper presents Spectrum, a hybrid nanophotonic-electric on-chip network that optimizes both throughput and latency. Spectrum's novel planar nanophotonic subnetwork broadcasts latency-critical...
The rough sets approach is used to provide a set of rules able to discriminate between law-abiding and defrauded Chinese listed companies in order to predict fraudulent financial reporting firms. The paper uses 767 Chinese listed companies as model samples and 116 Chinese listed companies as test samples, the extracted rules are based on attribute value importance and dominance-based rough sets approach...
Instantiation information of the design pattern which exists in the design model is always lost in the program, so the comprehension and reversion of the program become very difficult. We have proposed an approach to identify the design pattern information based on Java annotations. This approach defines the meta model of the design pattern, and uses Java annotation technology to annotate these meta...
