A concept map is a graphical tool for representing knowledge. They have been used in many different areas, including education, knowledge management, business and intelligence. Manually constructing concept maps can be a complex task; the unskilled person may encounter difficulties in determining and positioning concepts relevant to the problem area. An(More)
This article examines the possibility of publication of students’ data, such as secondary school success, state graduation exam scores and success during their first year of university study for analyses. In order to discover data patterns and relationships using data mining techniques, the data must be released in the form of original tuples, instead of(More)
We present a hardware-based implementation of Linear Program (LP) decoding for binary linear codes. LP decoding frames error-correction as an optimization problem. In contrast, variants of Belief Propagation (BP) decoding frame error-correction as a problem of graphical inference. LP decoding has several advantages over BP-based methods, including(More)
Fast growing e-commerce (electronic commerce) segment at first influenced big companies business that led to B2B (Business to business) e-commerce structure. This paper presents an application of standard ecommerce model in e-auction (electronic auction) process. In addition, based on the several auctions experiences, the recommendations for the real-time(More)
We detail a field-programmable gate array (FPGA) based implementation of linear programming (LP) decoding. LP decoding frames error correction as an optimization problem. This is in contrast to variants of belief propagation (BP) that view error correction as a problem of graphical inference. LP decoding, when implemented with standard LP solvers, does not(More)
In this paper we present an FPGA-based implementation of linear programming (LP) decoding. LP decoding frames error correction as an optimization problem. This is in contrast to variants of belief propagation (BP) decoding that view error correction as a problem of graphical inference. There are many advantages to taking the optimization perspective:(More)
The speed at which two remote parties can exchange secret keys over a fixed-length fiber-optic cable in continuousvariable quantum key distribution (CV-QKD) is currently limited by the computational complexity of post-processing algorithms for key reconciliation. Multi-edge low-density paritycheck (LDPC) codes with low code rates and long block lengths were(More)
Percent-done progress indicators are a technique for graphically showing how much of a long task has been completed. In the database environment such information is especially important during the long-running query execution. The proposed method constructs (during the learning phase) adaptive progress indicator model analyzing influence of averaged system(More)
