We present a preliminary study of using the template of an ensemble of evolving shells we developed for M 82 (Yao 2009). we apply the model to represent various stages of starburst evolution in a well known sample of nearby luminous infrared galaxies (LIRGs). In this way, we attempt to interpret the relationship between the degree of molecular excitation and ratio of far-infrared (FIR) to CO lu...

Purpose – Despite many technically sophisticated solutions, managing information security has remained a persistent challenge for organizations. Emerging IT/ICT media have posed new security challenges to business information and information assets. It is felt that technical solutions alone are not sufficient to address the information security challenge. It has been argued that organizations a...

Radiative transfer equilibrium models of nearby interstellar matter (ISM) are required to determine the boundary conditions of the heliosphere from astronomical observations of nearby stars. These models are also constrained by data on the ISM inside of the solar system, including pickup ion, anomalous cosmic rays, and in situ He data. The two best ISM models give semi-empirical filtration fact...

We have discovered a bow shock shaped mid-infrared excess region in front of δ Velorum using 24 μm observations obtained with the Multiband Imaging Photometer for Spitzer (MIPS). The excess has been classified as a debris disk from previous infrared observations. Although the bow shock morphology was only detected in the 24 μm observations, its excess was also resolved at 70 μm. We show that th...

Human factors are increasingly recognized as real culprits of failures in Information Security Management (ISM). Thus, the roles of Human Resource Management (HRM) become more salient with ISM. Unlike practitioners, researchers appear reluctant to acknowledge such emergence. Prior literature has not attempted to link ISM with HRM theoretically. ISM literature suggests that both technical and no...

We have used the Submillimeter Wave Astronomy Satellite to map the ground-state 110 → 101 transition of ortho-H2O at 557 GHz in the Orion molecular cloud. H2O emission was detected in Orion over an angular extent of about 20, or nearly 3 pc. The water emission is relatively weak, with line widths (3–6 km s−1) and VLSR velocities (9–11 km s−1) consistent with an origin in the cold gas of the mol...

We demonstrate an implicit space mapping (ISM) method for microwave filter design that is enhanced and assisted by a tuning procedure. This procedure helps us to select design variables as well as suitable preassigned parameters for an ISM implementation. It also aids us in the convergence of our ISM algorithm. We investigated and solved a microstrip notch filter using this technique. This show...

The issue of information security management (ISM) had been widely studied with different approaches and from different perspectives. To have the right security objectives is the primary step to achieving an effective security program. Based on the contingency theory, a conceptual model of factors that determine ISM objectives was proposed. To validate this model, a webbased survey with open-en...
