Ab stract In 1996 data from labo ra to ries, gen eral prac ti tio ners and a na tional em ployer were com bined to de tect trends in in flu enza ac tiv ity in Aus tra lia. An epi demic of in flu enza A (H3N2) was re corded. Lit tle in flu enza B ac tiv ity was noted through out the win ter months, how ever the number of labo ra tory re ports of in flu enza B rose in the last quar ter of the yea...

Tem po ral b-value vari a tions have been com pletely ob tained for the seis mic fault ing pro cess of the 4 March 2008 Taoyuan earth quake (ML = 5.2), south ern Tai wan. In ad di tion to trig ger ing sev eral hun dred after shocks, the mainshock was pre ceded by two groups of foreshocks (64 events) that clus tered along the nar row ma jor fault zone. A high b-value of ~1.25, es ti mated from t...

in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...

since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...

A global record (i.e. a set of local records, one for each process of an asyn-chronous computation) abstracts what is usually called global state, global checkpoint or global snapshot in particular problems. This paper concentrates on consistency of global records. First, a general model of asynchronous computations, including the classical shared memory model and several message passing models...

a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...

Structural reliability models suuer from some drawbacks mainly related to the assumptions necessary to apply them. We propose a model which intends to overcome some of these limitations appearing in previous published works. We discuss on an approach that can make more realistic the usual Markovian assumptions when considering the structural modeling of the execution process. Moreover, we deene...

Application generators have been demonstrated as a successful approach to achieving software reuse and typically yields higher productivity gains than methods such as component-based reuse. Despite their advantages, industrial software developers are reluctant to adopt these methods due to the lack of tools for constructing generators. This paper presents a framework for the development of appl...

Recently, there has been renewed interest in methods and techniques of reducing the confusion and uncertainty associated with the morass of spurious, computational poles that result from the traditional over-determined equation set in modal parameter estimation processes. In this paper, sev eral additional mechanisms for providing a clear stabilization, or consistency, diagram are presented. Am...

Previous work on human subjects (9) has shown that the polysaccharide associated with serum proteins is significantly elevated in malig nancy. Little is known concerning the correlation between this elevation and the cancerous condi tion. Work in this laboratory has shown that the serum polysaccharide of dogs is increased in sev eral types of experimental inflammation (7). An elevation also occ...
