C2H2 zinc fingers (C2H2-ZFs) are the most prevalent type of vertebrate DNA-binding domain, and typically appear in tandem arrays (ZFAs), with sequential C2H2-ZFs each contacting three (or more) sequential bases. C2H2-ZFs can be assembled in a modular fashion, providing one explanation for their remarkable evolutionary success. Given a set of modules with defined three-base specificities, modula...

The aim of this paper is to introduce and study a new concept ofstrong double $(A)_ {Delta}$-convergent sequence offuzzy numbers with respect to an Orlicz function and also someproperties of the resulting sequence spaces of fuzzy   numbers areexamined. In addition, we define the double$(A,Delta)$-statistical convergence of fuzzy  numbers andestablish some connections between the spaces of stron...

Losing weight by acupuncture is an old Chinese method. Nevertheless, many physician and even people don’t believe to it. The main goal of this study is effectiveness of acupuncture on obesity. This study includes some 40 patients aged 16-48 years, with male to female ratio 1 to 2, who fulfilled with obesity criteria of this study. On the base of Obesity syndrome of diagnosis the mains body poin...

The problem of node failures in interconnection networks has been extensively studied. In this paper we deene the notion of a more catastrophic form of failure | path failure | in which a sequence of nodes from a source to a sink in the network fail. The corresponding collapse in the structural properties of the underlying network is analyzed in quantitative terms, as a function of network size...

We consider a software reliability model where the failure rate of each fault depends on the specific operation performed. The software is tested in a given sequence of test cases for fixed durations of time to collect data on failure times. We present a Bayesian analysis of software failure data by treating the initial number of faults as a random variable. Our analysis relies on the Markov Ch...

Under incidental instructions, thirty-eight 2-year-olds were trained on a six-element deterministic sequence of spatial locations. Following training, subjects were informed of the presence of a sequence and asked to either reproduce or suppress the learned material. Children's production of the trained sequence was modulated by these instructions. When asked to suppress the trained sequence, t...

Al~traet--All failure detection methods are based, either explicitly or implicitly, on the use of redundancy, i.e. on (possibly dynamic) relations among the measured variables. The robustness of the failure detection process consequently depends to a great degree on the reliability of the redundancy relations, which in turn is affected by the inevitable presence of model uncertainties. In this ...

We consider a system which deteriorates with age and may experience a failure at any time instant. On failure, the system may be replaced or repaired. The repair can partially reset the failure intensity of the unit. Under a suitable cost structure it has been proved in the literature that the average-cost optimal policy is of control-limit type, i.e. it conducts a replacement if and only if, o...

This paper presents some solutions of decision-making aspects integrated in an approach of process failure monitoring suitable for complex systems like flexible manufacturing systems. A hierarchical and modular structure corresponding to the monitoring and control requirements is described. Each control and monitoring module is able to accept any signal from the lower levels of the hierarchy an...
