To increase the detection sensitivity of capillary electrophoresis (CE) and thereby widen its application to biomolecular analyses, we have developed a number of on-line preconcentration strategies, i.e., techniques to increase sample loading without compromising resolution and efficiency. Two such techniques, namely, dynamic pH junction and field-enhanced sample injection (FESI) are covered in...

In this work, we described a point-of-care (POC) dry-reagent strip biosensor (DRSB) based on enzyme tracers and portable strip reader for simple, low-cost and sensitive assay of protein detection in minutes. Horseradish Peroxidase (HRP) and Rabbit IgG (R-IgG) were used as a model system for the demonstration of the proof-of-concept. The sandwich-type immunoreactions were performed on the DRSB a...

A novel approach of the integrated security and dynamic Position Location and Tracking (PL&T) for malicious node maintaining two friendly nodes is proposed. Location based hash security scheme is deployed for detection of friendly and malicious nodes by encrypting hash functions using private location assets to increase the security level. In addition, PL&T is deployed forming the robust tracki...

In recent years, based on the growing importance of clean energy in comparison with conventional energy production from fossil fuels, DG systems are gradually becoming more popular all over the world. These resources solve many problem of system. However, these resources create some other problems too. One of the most problem of DGs is unwanted islanding. This paper addresses reliable passive i...

We have measured helium and neon concentrations, elemental and isotopic ratios of 91 individual presolar graphite grains from the KFC1 density separate of the Murchison meteorite. Eleven grains contain measurable amounts of either He, Ne, Ne or Ne, or a combination thereof. We report the first detection of Ne from an individual presolar graphite grain and the first detection of He and Ne in ind...

Event detection has advanced significantly in the past decades relying on pixeland feature-level representations of video-clips. Although effective those representations have difficulty on incorporating scene semantics. Ontology and description-based approaches can explicitly embed scene semantics, but their deterministic nature is susceptible to noise from underlying components of vision syste...

Intrusion Detection Systems (IDSs) for Mobile Ad hoc NETworks (MANETs) are indispensable since traditional intrusion prevention based techniques are not strong enough to protect MANETs. However, the dynamic environment of MANETs makes the design and implementation of IDSs a very challenging task. In this paper, we present a non-overlapping Zone-Based Intrusion Detection System (ZBIDS) that fits...

A new method for detection of zone-boundary phonons is reported. Phonons are detected by phonon difference absorption of far-infrared laser radiation. We present experimental results obtained for TlCl and TlBr crystals. Phonons are generated by nonradiative transitions in optically excited crystals. Our experiments indicate long-lived zone-boundary phonons at low crystal temperature and a stron...
