Standard Data Envelopment Analysis (DEA) is characterized by uniform proportional input reduction or output augmentation in calculating improvement projections. This paper develops a new Euclidean Distance Minimization model in the context of DEA in order to derive a more appropriate efficiency-improving projection model by means of a weighted projection function. The model is extended to the s...

A new theoretical model of grammatical picture generation called extended 2D context-free picture grammar (E2DCFPG) generating rectangular picture arrays ofsymbols is introduced. This model which allows variables in the grammar and uses the squeezing mechanism offorming the picture language over terminal symbols, is an extension of the pure 2D context-free picture grammar (P2DCFPG) [13]. The ex...

During the last decades, classical models in language theory have been extended by control mechanisms defined by monoids. We study which monoids cause the extensions of context-free grammars, finite automata, or finite state transducers to exceed the capacity of the original model. Furthermore, we investigate when, in the extended automata model, the nondeterministic variant differs from the de...

We establish a framework to integrate propositional logic with first-order logic. This is done in such a way that it optionally appears either as first-order logic over a Boolean algebra or as propositional logic including Boolean quantification. We describe and prove complexity bounds for extended quantifier elimination by virtual substitution for our theory. This extended quantifier eliminati...

The massive growth of social webs offer opportunities to communicate with diverse languages, unstructured text, informal posts, misspelled contents and emojis. Social media users feel comfortable express their emotions specially high intensity (hate speech) in mother tongue. Hate speech any form targets groups individuals that may trigger antisocial activities, hate crimes, terrorist acts. Beng...

Context information is not widely used while browsing the internet on mobile devices. With an adapted website, the content can become more suitable to the user. Currently, most examples of context-aware browsing are based on context information gathered by telecom providers, but mobile devices can also gather context information. In this paper, we investigate which context information can be ga...

The concept of a permutation representation has recently been extended from groups to quasigroups. Following a suggestion of Walter Taylor, the concept is now further extended to left quasigroups. The paper surveys the current state of the theory, giving new proofs where necessary to cover the general case of left quasigroups. Both the Burnside Lemma and the Burnside algebra appear in this new ...

the most frequent adverse effects of indomethacin like other nsaids are gastro–intestinal and central nervous system disturbances. extended release or enteric release formulations minimize these symptoms. the objective of this study was to develop an extended release pellet formulation of indomethacin by the centrifugation (rotary fluid bed granulation) or powder layering method. layered, nonpa...
