It is important for both network researchers and operators to know the behavior of mobile nodes (mobile hosts and mobile routers), and to find anomalies in their behavior. This paper describes an on-going effort within the Nautilus Project to provide a set of free tools to build a statistics repository, called SONAR, containing detailed information of mobile nodes. SONAR is especially designed ...

High-performance liquid chromatography (HPLC) is the most versatile of the chromatographic techniques because it is applicable to a wide variety of analytes. Unfortunately, liquid mobile phases have relatively low diffusivities. A novel approach is presented for increasing the diffusivity of a liquid mobile phase. The method advocated in this study is the first process that has been described b...

The non-invasive pulse-oximeter is a crucial parameter in continuous monitoring systems. It plays a vital role from admission of the patient to surgeries with general anaesthesia. The paper proposes the application of wavelet transform to delineate the raw plethysmograph signals obtained from basic portable and mobile-powered electronic hardware. The paper primarily focuses on finding peaks and...

mobile commerce is whatever electronic transfer or transaction via a mobile modem through a mobile net in which the true value or advance payment is done for goods, services or information. a mobile payment system should be beneficial for all related persons. for a payment system to be a successful system, end-user, seller, exporter and operators should see a additional value in it. end-user pr...

This report describes an automated coupled column microbore-high-performance liquid chromatography (HPLC) with fluorescence detection for direct determination of verapamil in small volume of rat plasma. We used HPLC system consisting of three columns such as precolumn, intermediate and analytical column and six-port switching valve and injected small volume of rat plasma to the system without s...

A novel, efficient and simple approach for soy phosphatidylcholine analysis according to its fatty acid composition was studied with reverse-phase high-performance liquid chromatography. The reverse-phase high-performance liquid chromatography analysis was performed isocratically using UV detector and simple mobile phase solvents consisting of isopropyl alcohol, methanol, and deionized water in...
