Mobile Cloud Computing (MCC) is an infrastructure where the data and the processing of data are outsourced. MCC integrates cloud computing into the mobile environment and executes the applications in the mobile device effectively by partitioning and offloading the computation intensive task to external resources (e.g. Public Clouds). The effective offloading is mainly focused on the decision ma...

Super/subcritical Fluid Chromatography (SFC) has been used successfully for the analysis of a variety of compounds including foods, polymers, and pharmaceuticals. 1-7 Supercritical carbon dioxide exhibits solvating power comparable to hexane and has been primarily utilized as a fluid for the separation of relatively non-polar compounds. 8 For this reason, many SFC methods have been developed as...

The challenges of wireless and mobile computing environments have attracted the attention of researchers to revisit the conventional implementation of distributed computing paradigms. In this paper we propose to revisit the conventional implementation of the Two Phase Commit (2PC) protocol which is a fundamental asset of transactional technology for ensuring the consistent commitment of distrib...

We present a Java library for mobile phones which tracks and controls at runtime the use of potentially costly resources, such as premium rate text messages. This improves on the existing framework (MIDP — the Mobile Information Device Profile [6]), where for example every text message must be authorised explicitly by the user as it is sent. Our resource management library supports richer proto...

Mobile computing has attracted attention of intensive researches during the recent years. Many papers revisit the conventional implementation of distributed computing paradigms for use in this new environment. A key paradigm of the transaction processing is the transaction commitment. A commitment mechanism such as Two Phases Commit (2PC) protocol, a fundamental asset of transactional technolog...

A new chromatographic procedure was proposed for the separation of propranolol (PRN) enantiomers based upon enantioselective chiral ligand-exchange chromatography. The separation was carried out on a short C8 column leading to considerably short separation time. L-alanine and Cu2+ were applied as chiral selector and central bivalent complexing ion, respectively. It was found that the kind of co...

In this paper, guanine and hypoxanthine were separated with four different ionic liquids as additives for the mobile phase using reversed phase high performance liquid chromatography (RPHPLC). The ionic liquids, 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIm][BF4]), 1-ethyl-3methylimidazolium tetrafluoroborate ([EMIm][BF4]), 1-ethyl-3-methylimidazolium methylsulfate ([EMIm][MS]) and 1-oct...

Typically, speaker identification examination requires two audio recordings: a voice sample and a questionable recording. The questionable one is in most of the cases the intercepted or recorded phone call. As mobile phones became the most popular way of communication, the largest number of questionable recordings comes from GSM channels. They use special algorithms and devices to transmit the ...

The retention model in HPLC is proposed, which is based on quasichemical equilibria of the components of the chromatographic system. This model provides a better undestanding of the retention mechanism in HPLC and it can be applied for quantitative description of the dependence of retention on the nature and composition of the mobile phase. H i g h performance liquid chromatography (HPLC) is kn...
