We define tree insertion systems which generates trees. The generative power is compared with the traditional generating and accepting devices for trees. Methods for conversion of tree insertion system to regular tree grammar and finite state bottom-up tree automata to tree insertion system are expalined with suitable examples. An outline of proof by induction for the equivalence of tree insert...

In the past few years several paper showed, that various generative mechanisms in formal language theory that used context-dependent insertions and deletions are capable of generating any recursively enumerable languages [1, 2, 3, 4, 5, 6, 7, 8, 9]. Since such systems are also models of molecular computing, for practical reasons it is important to examine these systems in a restricted case, in ...

In this chapter we focus on methods for injecting prior knowledge (represented in the form of nite automata) into adaptive recurrent networks. Several algorithms and architectures are described, including rst-order, second-order, and RBF-based recurrent neural nets.

In this article, we consider for the first time the operations of insertion and deletion working in a matrix controlled manner. We show that, similarly as in the case of context-free productions, the computational power is strictly increased when using a matrix control: computational completeness can be obtained by systems with insertion or deletion rules involving at most two symbols in a cont...

BACKGROUND The cardiovascular responses following the insertion of oropharyngeal airways in anaesthetized patients have been found to be of little consequence. However, those following the insertion of nasopharyngeal airways have not been studied. The aim of this investigation was to compare the cardiovascular responses to the insertion of oropharyngeal and nasopharyngeal airways in anaesthetiz...

VAR support should be supplied as close to the load as possible to minimize transmission losses. For voltage control and for improvement of total power factor in a distribution system the circuit- breaker switched capacitor banks can be used. The problems with this solution are the voltage steps caused by the large sizes of the capacitor banks as well as the transients caused on insertion. Thyr...

Endometriosis is a debilitating disorder, defined as the presence of endometrial gland and stroma outside of the uterus. It may affect angiogenesis and vascular endothelial growth factor (VEGF) is one of the angiogenic factors that plays an important role in both physiological and pathological angiogenesis. The present study aimed to evaluate the association of VEGF -2549 insertion/deletion (I/...

CODVerif is an approach that aims to verify the data being inserted in a store continuously. leverages combination of ontology and workflow technologies order define workflows are specific domain “monitoring insertion.” These domain-specific constrained on two dimensions: (1) They use set elements insertion” domain. (2) The logic these support predefined by relying common insertion scenarios. N...

The effect of hearing aid experience (measured as years of hearing aid use and user insertion gain at octave frequencies from 250 Hz to 4000 Hz) on the selection of preferred insertion gain under six listening conditions and one vocalization condition was examined. Thirteen experienced hearing aid users selected their preferred insertion gain in each test condition using a modified simplex proc...

INTRODUCTION In order to achieve a minimal trauma to the inner ear structures during array insertion, it would be suitable to control insertion forces. The aim of this work was to compare the insertion forces of an array insertion into anatomical specimens with three different insertion techniques: with forceps, with a commercial tool, and with a motorized tool. MATERIALS AND METHODS Temporal...
