Tourism and diversity by Zsuzsanna Bacsi

“…Besides, an ethnically or linguistically varied population can also provide a linguisticaly more skilful labour force, that is more sensitive to the needs of visitors coming from different cultures, and thus create a more comfortable environment for them. The issue of multicultural societies has recently become a sensitive issue, due to global mass migration. …”

External Fractional-Order Gradient Vector Perona-Malik Diffusion for Sinogram Restoration of Low-Dosed X-Ray Computed Tomography by Shaoxiang Hu

“…However, we argue that FSFOD is not the best way for diffusion since different parts of spatial derivative play different roles in Perona-Malik diffusion (PMD) and derivative orders should be decided according to their roles. Therefore, we adopt a novel fractional-order diffusion scheme, named external fractional-order gradient vector Perona-Malik diffusion (EFOGV-PMD), by only replacing integer-order derivatives of “external” gradient vector to their fractional-order counterparts while keeping integer-order derivatives of gradient vector for diffusion coefficients since the ability of edge indicator for 1-order derivative is demonstrated both in theory and applications. …”

Optimization and research on RFID anti-collision algorithm based on adaptive multi-dimension division code by Zhi-jin LI, Jie ZHOU, IAO-Jie Q, Wen-juan WU

“…Under the circumstance of many tags and many collisions,when multi-dimension division code algorithm is applied,the average number of times the reader calls each tag C(n) approximated to a limit 4/3,and the data conveyed by calling each tag tends to be a relatively small constant.However,under the circumstance of few collisions,the average number of times the reader calls each tag and the average data conveyed were relatively large.The adaptive multi-dimension division code algorithm,and the optimization of adaptive multi-dimension division code algorithm were proposed.The adaptive multi-dimension division code algorithm could adaptively decrease the MDDC dimensions according to the numbers of tags,and encode the tags again,hence greatly decrease the average number of times the reader calls each tag even under the circumstance of few tags.Therefore,in RFID system,adaptive multi-dimension division code algorithm can significantly improve the efficiency of searching for tags no matter in many collisions or in few collisions.…”

Qualitative modeling and analysis of attack surface for process multi-variant execution software system by Fukang XING, Zheng ZHANG, Ran SUI, Sheng QU, Xinsheng JI

“…Attack surface is an important index to measure security of software system.The general attack surface model is based on the I/O automata model to model the software system, which generally uses a non-redundant architecture and it is difficult to apply to heterogeneous redundant system architectures such as multi variant systems.Manadhatad et al.proposed a method to measure the attack surface in a dissimilar redundancy system.However, the voting granularity and voting method of the system architecture adopted by Manadhatad are different from those of the multi-variant system, which cannot accurately measure the attack surface of the multi variant system.Therefore, based on the traditional attack surface model, combined with the characteristics of heterogeneous redundant architecture of multi variant systems, the traditional attack surface model was extended and the attack surface model of multivariant systems was constructed.The attack surface of the multi variant system was represented in a formal way, and the traditional attack surface model was improved according to the voting mechanism of the multi variant system at the exit point of the system, so that it can explain the phenomenon that the attack surface of the multi variant system shrinks.Through this modeling method, the change of the attack surface of the multi variant system adopting the multi variant architecture can be explained in the running process.Then, two groups of software systems with multi variant execution architecture were used as analyzing examples.The attack surface of the software systems with the same functions as those without multi variant architecture were compared and analyzed in two situations of being attacked and not being attacked, reflecting the changes of the multi variant system in the attack surface.Combining the attack surface theory and the characteristics of the multi variant execution system, an attack surface modeling method for the multi variant execution system was proposed.At present, the changes of the attack surface of the multi variant execution system can be qualitatively analyzed.In-depth research in the quantitative analysis of the attack surface of the multi variant execution system will be continually conducted.…”
