A comparison of implications in orthomodular quantum logic-morphological analysis of quantum logic

引用

International Journal of Mathematics and Mathematical sciences 2012年第1期2012卷

作者： Fujio, Mitsuhiko Department of Systems Design and Informatics Faculty of Computer Science and Systems Engineering Kyushu Institute of Technology Iizuka-shi 820-8502 Japan

Morphological operators are generalized to lattices as adjunction pairs (Serra, 1984;Ronse, 1990;Heijmans and Ronse, 1990;Heijmans, 1994). In particular, morphology for set lattices is applied to analyze logics through Kripke semantics (Bloch, 2002;Fujio and Bloch, 2004;Fujio, 2006). For example, a pair of morphological operators as an adjunction gives rise to a temporalization of normal modal logic (Fujio and Bloch, 2004;Fujio, 2006). Also, constructions of models for intuitionistic logic or linear logics can be described in terms of morphological interior and/or closure operators (Fujio and Bloch, 2004). This shows that morphological analysis can be applied to various non-classical logics. On the other hand, quantum logics are algebraically formalized as orhomodular or modular ortho-complemented lattices (Birkhoff and von Neumann, 1936;Maeda, 1980;Chiara and Giuntini, 2002), and shown to allow Kripke semantics (Chiara and Giuntini, 2002). This suggests the possibility of morphological analysis for quantum logics. In this article, to show an efficiency of morphological analysis for quantum logic, we consider the implication problem in quantum logics (Chiara and Giuntini, 2002). We will give a comparison of the 5 polynomial implication connectives available in quantum logics. © 2012 Mitsuhiko Fujio.

The presence of motion artifacts in the photoplethysmographic (PPG) signals is one of the major obstacles in the extraction of reliable cardiovascular parameters in real time and continuous monitoring applications. In the current paper we present an algorithm for motion artifact detection, which is based on the analysis of the variations in the time and period domain characteristics of the PPG signal. The extracted features are ranked using a feature selection algorithm (NMIFS) and the best features are used in a Support Vector Machine classification model to distinguish between clean and corrupted sections of the PPG signal. The results achieved by the current algorithm (SE: 0.827 and SP: 0.927) show that both time and especially period domain features play an important role in the discrimination of motion artifacts from clean PPG pulses.

Malware writers attempt to generate different shapes of a malware to evade the signature-based scanners. As the number of variants of a metamorphic malware is increased, the analysis of all variants and selecting the appropriate signature and updating the database of the antivirus becomes more tiresome and time-consuming. Furthermore, for automated generated metamorphic viruses, which utilize the virus kits to produce different instances, sometime it is not possible to analyze all of them. Therefore, use of some classification methods to speed up the analysis process is necessary. In this paper, we show that how the histogram of instructions opcodes can help us in classification of metamorphic virus family variants.

Journal of Software engineering and Applications 2012年第5期5卷 340-350页

作者： Badariah Solemon Shamsul Sahibuddin Abdul Azim Abdul Ghani Advanced Informatics School Universiti Teknologi Malaysia Kuala Lumpur Malaysia Department of Software Engineering College of IT Universiti Tenaga Nasional Kajang Malaysia Faculty of Computer Science and Information Technology Universiti Putra Malaysia Serdang Malaysia.

It is widely acknowledged that Requirements engineering (RE) has an important implication for the overall success of software or system development projects. As more and more organizations consider RE as the principal problem areas in the projects, improving RE process therefore appears critical for future business success. Moreover, nowadays there are evidences that support improving RE process maturity can contributes to improved business performance. There exist generic Software Process Improvement (SPI) standards, specialised RE process improvement models as well as guidance and advices on RE. However, they suffer from various issues that limit their adoption by organizations that are interested to assess and improve their RE process capability. Therefore, the research presented in this paper proposes a new RE process improvement model. The model is built by adapting and expanding the structure of the continuous representation of the formal maturity framework Capability Maturity Model Integration for Development (CMMI-DEV) developed by the Software engineering Institute (SEI) through three rounds of development and validation stages, which involved RE and CMMI expert panel in the software industry. This paper aims to provide an overview on what, why and how we build the maturity model for RE. The intention is to provide a foundation for future development in the area of RE process improvement.

The production of the prompt charmed mesons D0, D+, and D*+ relative to the reaction plane was measured in Pb-Pb collisions at a center-of-mass energy per nucleon-nucleon collision of sNN=2.76TeV with the ALICE detector at the CERN Large Hadron Collider. D mesons were reconstructed via their hadronic decays at central rapidity in the transverse-momentum (pT) interval 2–16 GeV/c. The azimuthal anisotropy is quantified in terms of the second coefficient v2 in a Fourier expansion of the D-meson azimuthal distribution and in terms of the nuclear modification factor RAA, measured in the direction of the reaction plane and orthogonal to it. The v2 coefficient was measured with three different methods and in three centrality classes in the interval 0%–50%. A positive v2 is observed in midcentral collisions (30%–50% centrality class), with a mean value of 0.204−0.036+0.099 (tot. unc.) in the interval 2

Measurements of multiparticle azimuthal correlations (cumulants) for charged particles in p-Pb at sNN=5.02 TeV and Pb-Pb at sNN=2.76 TeV collisions are presented. They help address the question of whether there is evidence for global, flowlike, azimuthal correlations in the p-Pb system. Comparisons are made to measurements from the larger Pb-Pb system, where such evidence is established. In particular, the second harmonic two-particle cumulants are found to decrease with multiplicity, characteristic of a dominance of few-particle correlations in p-Pb collisions. However, when a |Δη| gap is placed to suppress such correlations, the two-particle cumulants begin to rise at high multiplicity, indicating the presence of global azimuthal correlations. The Pb-Pb values are higher than the p-Pb values at similar multiplicities. In both systems, the second harmonic four-particle cumulants exhibit a transition from positive to negative values when the multiplicity increases. The negative values allow for a measurement of v2{4} to be made, which is found to be higher in Pb-Pb collisions at similar multiplicities. The second harmonic six-particle cumulants are also found to be higher in Pb-Pb collisions. In Pb-Pb collisions, we generally find v2{4}≃v2{6}≠0 which is indicative of a Bessel-Gaussian function for the v2 distribution. For very high-multiplicity Pb-Pb collisions, we observe that the four- and six-particle cumulants become consistent with 0. Finally, third harmonic two-particle cumulants in p-Pb and Pb-Pb are measured. These are found to be similar for overlapping multiplicities, when a |Δη|>1.4 gap is placed.

This paper investigates the multirobot task allocation problem for a group of heterogeneous mobile robots while considering the resource constraints. The robots and tasks are characterized by resources as required by task execution. We propose to formulate this problem as a synchronization/simultaneity constrained set-partitioning mixed integer programming problem. The branch-and-bound approach is used to derive the optimal solution. Simulations for a small group of mobile robots demonstrate the effectiveness of the proposed approach. © 2012 IEEE.

In a supervised learning, the relationship between the available data and the performance (what is learnt) is not well understood. How much data to use, or when to stop the learning process, are the key questions. In the paper, we present an approach for an early assessment of the extracted knowledge (classification models) in the terms of performance (accuracy). The key questions are answered by detecting the point of convergence, i.e., where the classification model's performance does not improve any more even when adding more data items to the learning set. For the learning process termination criteria we developed a set of equations for detection of the convergence that follow the basic principles of the learning curve. The developed solution was evaluated on real datasets. The results of the experiment prove that the solution is well-designed: the learning process stopping criteria are not subjected to local variance and the convergence is detected where it actually has occurred. © 2012 Vilnius Universit.
