In this paper a new approach is shown for a monolingual extrinsic plagiarism detection system based on a modification of the "n-gram" concept (named “contextual n-gram”), a new high performance Information Retrieval engine based on this new concept, and a new strategy (“referential monotonity”) for plagiarism detection and its limits. The assessment results can be compared with those results ca...

The Dye Sensitized Solar Cell (DSSCs) has emerged as attractive and promising solar cells in recent years. It offers technically and economically viable option to p-n junction solar cells. However, the efficiencies of DSSCs could not compete with those of silicon solar cells. Numerous researches have been done to enhance the efficiencies of these cells over the past decades. Efficiencies up to ...

oils and fats are substances that are important nutritionally and have important role and impact on human health. energy consumption and preservation in respect of food industry and the increase in the world population and search for new sources of oils and fats to full fill the need of the society particulary the nutritional requirements have introduced this research topic. therefore aim of th...

An automatic word spacing is one of the important tasks in Korean language processing and information retrieval. Since there are a number of confusing cases in word spacing of Korean, there are some mistakes in many texts including news articles. This paper presents a high-accurate method for automatic word spacing based on self-organizing -gram model. This method is basically a variant of -gra...

Of numerous proposals to improve the accuracy of naive Bayes by weakening its attribute independence assumption, both LBR and TAN have demonstrated remarkable error performance. However, both techniques obtain this outcome at a considerable computational cost. We present a new approach to weakening the attribute independence assumption by averaging all of a constrained class of classifiers. In ...

crop rotation affect on crop nitrogen uptake and nitrogen use efficiency (nue). crop rotations with high nue decrease energy use and increase level of sustainability in agro ecosystems. the objectives of this research were to determine the suitable double cropping system for enhancing nue and evaluate the effects of crop rotation, n fertilizer rate and return of crop residue on nue. this study ...

With core counts as well as heterogeneity on the rise, the sequential components of applications are becoming the major bottleneck in performance scaling as predicted by Amdahl’s law. We are therefore faced with the simultaneous problems of occupying an increasing number of cores and improving sequential performance. In this work, we specifically focus on improving the energy efficiency of sequ...

In a recent issue of this JournuZ, Richard 0. Zerbe [7] considered the effects of alternative assignments of liability for damage in the field of pollution control and presented a useful categorization and analysis of alternative methods of achieving any particular level of control. In the process, Zerbe makes some rather strong claims for the “Coase theorem” which deserve further discussion. F...

We extend a recently proposed algorithm for n-best unpacking of parse forests to deal efficiently with (a) Maximum Entropy (ME) parse selection models containing important classes of non-local features, and (b) forests produced by unification grammars containing significant proportions of globally inconsistent analyses. The new algorithm empirically exhibits a linear relationship between proces...
