Research clues can be expressed as coherent chains of keywords grouped by theme. Capturing clues to research from the vast and expanding medical literature is valuable. Yet, it is difficult to automatically create clear visualizations of research clues despite the presence of many competing summarization tools. In this paper, we propose a linear classifier based on a spiral, which we call a regional...
With the rapid development of VLSI (very large scale integrated circuits), programmable logic devices have made great progress in integration level, manufacturing technology and encapsulation technique, which make its functions more complex and the reverse analysis of it becomes more difficult. As an important component of the reverse analysis of the logic-unknown chip, the processing capacity and...
Reverse analysis of chip is developed basing on the need of discovering design defection and eliminating hardware security vulnerability, automatic testing and diagnosis of electronic equipments. Nowadays it is the main direction of information security study as well. The data collection which is the key part of the chip reverse analysis is studied in this paper. The completeness of data collection...
A model based on Bell-LaPadula model is proposed for access control in hierarchical organizations which have hierarchical units. These units include departments, staff and a new concept named post. In the model proposed by this paper, relationships among units in organization are built, and security tags can be assigned to subjects and objects simply. The interoperation among different departments...
Binary relations and its operations are important in set theory. But traditional research mainly focuses on pure mathematics operations on set theory. Pansystems strengthen the research work in set theory by combining mathematics with its philosophical background. In this paper, using pansystems PMT-combination method, we re-inspect the philosophical background of binary relations and give a new interpretation...
During the development of programming languages, there always have some problems such as the AOP in the procedure-oriented languages and object-oriented languages. These problems appear frequently in software and are difficult to be coped with. Many problems are due to the limitation of theoretical foundations of these programming languages, thus they cannot be solved by simply applying some specific...
Generally, the code excited linear predictive (CELP) coding is known as one of the best algorithms for bit rate between 4 kbps and 16 kbps. Recently, the algebraic CELP (ACELP) algorithm has been widely adopted in standard speech coders such as G.729 and Adaptive multi rate (AMR) and AMR Wide Band (AMR-WB).In order to improve the speech quality based on CELP algorithm, harmonic Pitch pre-emphasis...
