This paper presents a simple tool to monitor and control incoming network traffic. The tool has been successfully used for shielding off systems and for detection of cracker activity. It has no impact on legal computer users, and does not require any change to existing systems software or configuration files. The tool has been installed worldwide on numerous UNIX systems without any source code...

Providing real-time information on the chemical properties of hydrocracking bottom oil (HBO) as feedstock for ethylene cracker while minimizing processing time, is important to improve optimization production. In this study, a novel approach estimating HBO samples was developed basis near-infrared (NIR) spectra. The main noise and extreme in spectral data were removed by combining discrete wave...

Walnut (Juglans regia L.) were evaluated for some physical properties and chemical composition. Ripe fruits were determined for moisture (2.71 %), crude protein (14.6 %) crude fibre (1.8%) ash (1.57%), crude energy (576Cal) ether soluble extract (24.71%), nut (10.5g) and kernel (5.09g) veights. Relative density, refractive index...

The specification, based on experimental data, of functions which characterize an object under investigation, constitutes one of the main tasks in modern science and technological problems. A typical example here is the estimation of density function of random variable distribution from any given sample. The classical procedures rely here on arbitrary assumption of the form of this function, an...

Kernel size is the main hazelnut quality parameter for consumption market. However, industrial purposes are destination cultivars. This work aims to identify aptitude relationships kernel size, and qualitative nut traits eligible enhance hazelnut’s commercial value. The of cv “Negret” “Pauetet” were assessed via in-shell shelled sizes two years. In-shell hazelnuts tested weight, shape, percent ...

Opting an appropriate dietary regime has been and will be one of the simplest ways of providing health for and preventing disorders of human beings. Cardiovascular diseases-one of the most prevalent causes of morbidity and mortality worldwide-are in particular related to diet. Atherosclerosis, the most common pathogenic process of cardiovascular disease, is closely connected with food ingredien...

Denaturing high-performance liquid chromatography (DHPLC) has quickly become popular as a tool for the automated discovery of single base substitutions as well as small insertions and deletions (1,2). Under partially denaturing conditions, heteroduplices are retained for a shorter time than their corresponding homoduplices on a DNA separation matrix. We have identified a contaminant emanating f...

This paper analyzes the changing relationship of tacit to codified knowledge over three industrial revolutions. Knowledge is increasingly “polyvalent” as theoretical, practical and interdisciplinary implications form a common center of gravity. The changing nature of knowledge drives the institutional spheres of university and industry together in advanced industrial societies and developing co...
