With the rapid growth of computer networks, more and more users access the remote server’s service in a distributed computing environment. Due to the fast development of the Internet and wireless communications, many activities like online-shopping, online banking, online voting are conducted over it. Authentication is one of the essential security features of network communication. The authent...

Smart cards have been commercial products for 15 years, but they have only found use in a broad range of applications in the past few years. Most early applications, such as prepaid phone cards, used memory cards with access logic. Adding a CPU to the card enhanced the security and paved the way for more possibilities: subscriber identification module (SIM) cards in cellular phones, banking car...

We report a 0.15 μm p-HEMT dual frequency VCO. The dual frequencies are achieved using a switchedresonator topology. Large devices can be used for switching, as their parasitic capacitance is absorbed into the resonator. The phase noise at 1 MHz offset was -101 dBc and -92 dBc at 10.6 and 16.3 GHz respectively.

Bactrian camels may have a unique gastrointestinal (GI) microbiome because of their distinctive digestive systems, unique eating habits and extreme living conditions. However, understanding of the microbial communities in the Bactrian camel GI tract is still limited. In this study, microbial communities were investigated by comparative analyses of 16S rRNA hypervariable region V4 sequences of f...

The project envisages the implementation of an e-payment system utilizing FIPS-201 Smart Card. The system combines hardware and software modules. The hardware module takes data insertions (e.g. currency notes), processes the data and then creates connection with the smart card using serial/USB ports to perform further mathematical manipulations. The hardware interacts with servers at the back f...

BACKGROUND Severity classification systems aim to stratify patients with acute pancreatitis reliably into coherent risk groups. Recently, the Atlanta 1992 classification has been revised (Atlanta 2012) and a novel determinant-based classification (DBC) system developed. This study assessed the ability of the three systems to stratify disease severity among patients with acute pancreatitis. ME...

Conventional imaging procedures have proved of limited value in assessing tumor response to neoadjuvant chemotherapy in locally advanced primary breast cancer (LAPBC). We evaluated the usefulness of radioisotopic procedures comparing planar scintimammography (SM) to SPECT, monitoring pre-surgery neoadjuvant chemo- or hormonotherapy response in 32 LAPBC patients. In all cases, 99mTc-tetrofosmin ...

Numerous information technology (IT)-based innovations from automated teller machines to electronic banking have already changed the customer-bank-interaction. Banks learned that these innovations require close integration with the existing channels, processes and systems in the front as well as in the backend. In view of a still dynamic pace of technological evolution, this research provides a...

AKKI (Association of Indonesian Credit Card Issuers) is an organization that aims to build a healthy credit card industry and responsible for Issuers, Cardholders, Merchants, Principals (American Express, JCB International, MasterCard International Visa International) other parties related. in collaboration with its members also builds sound safe infrastructure. currently has 24 issuing institu...

A series of mononuclear iron(III) complexes of the type [Fe(L)Cl(3)], where L is a systematically modified N(2)O or N(3)O ligand with a methoxyethyl/tetrahydrofuryl ether oxygen donor atom, have been isolated and studied as models for catechol dioxygenases. The X-ray crystal structures of [Fe(L2)Cl(3)] 2, [Fe(L6)Cl(3)] 6, [Fe(L5)(TCC)Cl] 5a, where H(2)TCC = tetrachlorocatechol, [Fe(L6)(TCC)Br] ...
