Detecting tattoo images stored in information technology (IT) devices of suspects is an important but challenging task for law enforcement agencies. Recently, the U.S. National Institute of Standards and Technology (NIST) held a challenge and released a tattoo database for the commercial and academic community in advancing research and development into(More)
A dual-layer electromagnetic band-gap (EBG) mushroom structure is proposed in this paper. Based on the concept of slow-wave propagation, this structure can reduce the size of multi-element microstrip patch antennas (MPAs) by 61%. While the mushroom inner layer aids in the antenna miniaturization, the more compact upper layer acts as a band-stop filter(More)
Based on the concept of slow wave propagation, a dual-layer electromagnetic band gap (EBG) mushroom structure is used to reduce the area of a patch multi-antenna sub-system. While the inner layer aids in the antenna miniaturization, the more compact upper layer helps in further reduction of the mutual coupling between the miniaturized patch antennas which(More)
Smartphones efficiently collect traffic information, guide the drivers and inform the end-user about the current and future traffic conditions. Due to enhanced sensor technology, visualization capabilities, navigational performance and network connectivity, smartphones play an important role in advanced travel information systems (ATIS). Although they offer(More)
This paper investigates various designs of 4-element miniaturized Planar Inverted-F Antennas (PIFA) with pattern and polarization diversity at 2.45 GHz. The antennas are only 13mm x 7mm in area and built on a small ground plane size of 105 mm x 55 mm. Diversity performance criteria namely the Envelope Correlation Coefficient (ECC) and Mean Effective Gain(More)
Tumor-site-specific delivery of anti-cancer drugs remains one of the most prevailing problems in cancer treatment. While conventional means of chemo-delivery invariably leave different degrees of side-effects on healthy tissues, in recent times, intelligent chemical designs have been exploited to reduce the cross-consequences. In particular, the strategies(More)
Photothermal therapy using (Near Infrared) NIR region of EM spectrum is a fast emerging technology for cancer therapy. Different types of nanoparticles may be used for enhancing the treatment. Though the treatment protocols are developed based on experience driven estimated temperature increase in the tissue, it is not really known what spatiotemporal(More)
