Multi-Criteria Group Decision Making with Picture Linguistic NumbersIn this paper, motivated by picture fuzzy sets and linguistic approaches, the notion of picture linguistic numbers are first defined. We propose the score, first accuracy and second accuracy of picture linguistic numbers, and propose a simple approach for the comparison between two picture linguistic numbers. Simultaneously, the operation l...

An Experimental Investigation of Part-Of-Speech Taggers for VietnameseIn this paper, we present an experimental investigation of five part-of-speech taggers for Vietnamese. In the investigation, there are four statistical taggers, Stanford POS Tagger, ClearNLP, vnTagger and JVnTagger. The other one is RDRPOSTagger,a transformation-based tagger. In term of tagging accuracy, we evaluate the statistical taggers b...

Towards Model-Checking Probabilistic Timed Automata against Probabilistic Duration PropertiesWe have presented the problem of checking probabilistic timed automata against probabilistic duration calculus formulas. The problem is decidable for a class of PDC formulas of the form [Ψ]wλ where Ψ is a linear duration invariant, or a DC formula for bounded liveness. The technique for model checking is an extension of our techniques for ch...

An OCL-Based Framework for Model TransformationsWe have introduced an approach for specifying, realizing, and ensuring the quality of model transformations: (1) The foundation of the approach is based on the integration of TGGs and OCL. We have further formulated operation contracts for derived triple rules in order to realize them as OCL operations with two views: Declarative OCL pre- an...

Reducing Startup Time in MP4 On-Demand Video Streaming Services with Movie Atom CachingIn this paper, we have shown that in streaming schemes where MP4 files are used as multimedia assets, time for downloading moov atoms, a data segment in MP4 files which is important for decoding process, is noticeable. This amount of time leads to long startup delays and poor quality of experience. User behavior models were presented to show...

Hyper-Volume Evolutionary AlgorithmIn this paper we proposed a multi-objective evolutionary algorithm called Hyper-volume Evolutionary Algorithm (HVEA) which incorporates distinctive mechanisms for fitness assignment, ranking and crowding. The algorithm uses hyper-volume, Pareto dominance and distance between neighbouring solutions in order to drive improvement of the current...

A Watermark Algorithm Against De-Synchronization AttacksIn this paper, we have presented a novel content based image watermarking operating in the DoG scale space with enhancing robustness against de-synchronization attacks. Such watermarking methods present additional advantages over the published watermarking schemes in terms of detection and recovery from geometric attacks, and with better sec...

Kinect Based Character Navigation in VR GameIn the paper, we proposed a technique to navigate characters by hand actions in VR game. A Kinect was used to obtain the hand actions. In this technique, we also suggested using the marker attached to the player’s hand to increase the accuracy of hand action recognition. So, we not only take advantage of low-cost device but also enhance flex...
