Extract-Transform-Load (ETL) flows periodically populate data warehouses (DWs) with data from different source systems. An increasing challenge for ETL flows is processing huge volumes of data quickly. MapReduce is establishing itself as the de-facto standard for large-scale data-intensive processing. However, MapReduce lacks support for high-level ETL specific constructs, resulting in low ETL ...

Sickle cell disease is one of the commonest reasons for hospital admissions in Bahrain and it considered one of the most significant causes of morbidity and mortality. However, HRQOL in SCD patients is not well studied in this part of the world. SF 36 questionnaire was administered to a total of 1886 participants, through manual and online methods in Salmanya Medical comlex and health centers o...

The results of bar-driven mass inflow are directly observable in high-resolution HST observations of their circumnuclear regions. These observations reveal a wealth of structures dominated by dust lanes, often with a spiral-like morphology, and recent star formation. Recent work has shown that some of these structures are correlated with the presence or absence of a bar. I extend this work with...

We present a study of the X-ray properties of the nearby face-on Scd spiral galaxy M101 based on recent XMM-Newton observations. In this third and final paper in the present series, we focus on the spatial and spectral properties of the residual emission, after excluding bright X-ray sources with L X > 10 37 erg s −1. Within a central region of radius 10 ′ (21 kpc), the X-ray emission broadly t...

The κ-space three-dimensional parameter system was originally defined to examine the physical properties of dynamically hot elliptical galaxies and bulges (DHGs). The axes of κ-space are proportional to the logarithm of galaxy mass, mass-to-light ratio, and a third quantity that is mainly surface brightness. In this paper we define self-consistent κ parameters for disk galaxies, galaxy groups a...

Recent studies of deep mantle structure indicate strong heterogeneity. To conduct highresolution waveform modelling of these structures, we have developed a new method to construct 2-D synthetics directly from block-style tomographic models. Unlike the WKBJ approximation, which utilizes rays overshooting and undershooting receivers, our method (WKM approximation) uses rays that arrive at the re...

The GALFORM semi-analytic model of galaxy formation is used to explore the mechanisms primarily responsible for the three types of galaxies seen in the local universe: bulge, bulge+disc and disc, identified with the visual morphological types E, S0/a-Sbc and Sc-Scd, respectively. With a suitable choice of parameters the GALFORM model can accurately reproduce the observed local Ks-band luminosit...
