Elemental mercury poisoning most commonly occurs through vapor inhalation as mercury is well absorbed through the lungs. Administering subcutaneous and intravenous elemental mercury is very uncommon but with only a few isolated case reports in the literature. We present an unusual case of elemental mercury poisoning in a 20-year-old young male who presented(More)
Distance measures are part and parcel of many computer vision algorithms. The underlying assumption in all existing distance measures is that feature elements are independent and identically distributed. However , in real-world settings, data generally originate from heterogeneous sources even if they do possess a common data-generating mechanism. Since(More)
In recent years, orthogonal frequency division multiplexing (OFDM) is considered as one of the key technologies for high data wireless communication systems. One of the main disadvantages of an OFDM system is its high peak to average power ratio (PAPR), which causes distortion in signal at the nonlinear high power amplifier (HPA) of OFDM transmitter [1-10].(More)
Dielectric properties of the nanocrystalline polymers such as polyvinylidenefluoride have been investigated with and without nanofilleres (i.e. BaTiO<sub>3</sub> nanoparticles) at frequency ranges from 100 Hz to 1 MHz range in the temperature range from 30 to 150&#x00B0;c. The increase in permittivity with temperature may be due increase in molecular(More)
Clustering is an unsupervised learning technique in which data or objects are grouped into sets based on some similarity measure. Most of the clustering algorithms assume that the main memory is infinite and can accommodate the set of patterns. In reality many applications give rise to a large set of patterns which does not fit in the main memory. When the(More)
Unimolecular dissociation dynamics of a model three degree of freedom triatomic molecule is studied in order to understand the mechanisms for deviations from statisticality. Performing a wavelet based time-frequency analysis of the dynamics allows for the dynamics to be followed on the network of nonlinear resonances, also called as the Arnold web. The(More)
Orthogonal frequency division multiplexing (OFDM) is a key modulation technique to provide a high performance physical layer in modern wireless systems. Orthogonal frequency multiple accesses (OFDMA) is one of the best ways to resource allocations in OFDM systems. Resource allocation schemes are required to be optimized to improve performance of OFDMA based(More)
Software testing is an investigation which is performed to provide stakeholders with information about the quality of the product or service under test. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Test techniques include, but are not(More)
