The Potential of Artificial Intelligence in IT Project Portfolio Selection

The rapid growth of innovative technologies and the complexity of IT projects lead to the change in the tools and competency required for organization management and project management. Also, the scope of an IT product is no longer within a single project and team but requires the collaboration among multiple projects, teams and the alignment with the organization’s strategies. Therefore, project portfolio selection becomes a challenging process due to the complexity and uncertainty of various factors and risks. In the IT industry, the emergence of artificial intelligence (AI) could bring opportunities to organizations to address different challenges including challenges in project portfolio selection. In this paper, we have discussed the current challenges in IT project portfolio selection, the available methods and tools and their limitations. Then an overview of the potential applications of AI in IT project portfolio selection is explored. Finally, we conclude the paper by providing future research directions

Design Considerations for a Disaster eHealth Appliance

Disaster eHealth is a new area of research and endeavour. In order to make a practical contribution Disaster eHealth approaches should consider the role of a Disaster eHealth appliance. Both disaster management and disaster medicine may find that such approaches allow critical information to be gathered and situational awareness improved. This paper proposes the development of a Disaster eHealth appliance to support self-care of chronic disease and caregiving by others. Injuries and disease caused by the disaster may be also supported by this approach. It also attempts to address some of the potential problems and suggest some solutions for the use of such appliances. Re-using existing devices may offer a relatively low-cost and sustainable approach to providing such devices, and infrastructure to use them. &nbsp

Temporary Access to Medical Records in Emergency Situations

Access to patients Electronic Health Records (EHR) is a daily operation in mainstream healthcare. However, having access to EHR in emergencies while is vitally important to save patients’ life, it could potentially lead to security breaches and violating patients’ privacy. In this regards, getting access to patients’ medical records in emergency situations is one of the issues that emergency responder teams are facing. This access can be temporary until patients reach hospitals or healthcare centers. In this paper, we aim to explore different technology-based solutions to give responders temporary access to patients\u27 medical records in emergency situations. The core of this study is patients and responders authentication methods that can save precious emergency time and protect the privacy and confidentiality of patients data to the utmost. We also have explored control access mechanism and security audits to increase the security of the procedure and patient privacy

External Plasma Interactions with Nonmagnetized Objects in the Solar System

The absence of a protecting magnetic field, such as the dipole magnetic field around Earth, makes the interaction of solar wind with unmagnetized objects particularly interesting. Long-term evolution of the object’s surface and atmosphere is closely tied to its interaction with the outer space environment. The ionospheric plasma layer around unmagnetized objects acts as an electrically conducting transition layer between lower atmospheric layers and outer space. This study considers two distinct types of unmagnetized objects: Titan and comet 67P/Churyumov-Gerasimenko (67P/CG). For many years, Titan has been a key target of the National Aeronautics and Space Administration (NASA) Cassini mission investigations; and the European Space Agency (ESA) Rosetta spacecraft explored comet 67P/CG for more than two years. Ionospheric composition and primary ion production rate profiles for Titan are modeled for various solar activity conditions. Photoionization is the main source of ion production on the dayside; on the nightside, electron-impact ionization is the main ionization source. This dissertation uses model results and in-situ measurements by the Ion and Neutral Mass Spectrometer (INMS) and the Langmuir Probe (LP) onboard the Cassini spacecraft to show that while the solar activity cycle impacts the primary ion species significantly, there is little effect on heavy ion species. Solar cycle modulates the Titan’s ionospheric chemistry. The solar cycle effects of on each ion species are quantified n this work. In some cases the solar zenith angle significantly overshadows the solar cycle effects. How each individual ion reacts to changes in solar activity and solar zenith angle is discussed in details. A method to disentangle these effects in ion densities is introduced. At comet 67P/CG, the fast-moving solar wind impacts the neutral coma. Two populations of electrons are recognizable in the cometary plasma. These are the hot suprathermal electrons, created by photoionization or electron-impact ionization, and the cold/thermal electrons. Even though photoionization is the dominant source of ion production, electron-impact ionization can be as high as the photoionization for certain solar events. At 3 AU, electron energy spectra from in-situ measurements of the Ion and Electron Sensor (IES) instrument exhibit enhancement of electron fluxes at particular energies. Model-data comparisons show that the flux of electrons is higher than the typical solar wind and pure photoionization fluxes. The probable cause of this enhancement is the ambipolar electric field and/or plasma compression. This research also discusses formation of a new boundary layer around the comet near perihelion, similar to the diamagnetic cavity at comet 1P/Halley. At each crossing event to the diamagnetic cavity region, flux of suprathermal electrons with energies between 40 to 250 eV drops. The lower flux of solar wind suprathermal electrons in that energy range can cause this flux drop

Gender and Age Differences in Marital Intimacy Levels among Iranian Married Couples in Malaysia

This study aimed to establish the differences in marital Intimacy based on gender and age variables. Subjects for this study were 257 married couples (131 females and 126 males aged 25 to 50 years) from 4 public university in Malaysia. The collecting data for the study were through the use of quantitative method. The instrument used was Personal Assessment of Intimacy in Relationships (PAIR) questionnaire to measure marital intimacy level and demographic form for collecting demographic data. The results illustrated the intimacy level of females was higher than men. Statistically, the male and female students significantly differed in their intimacy scores. Also, there is significant differences between Intimacy level and age among married couples. In addition, general age differences in intimacy demonstrated older couples has higher level of intimacy. Consequently, implications of the study give valuable insight to the future use of couple therapist in society. Family therapists can work with couples for nurturing their intimacy thereby control and handling couples conflicts by knowing about spouses differences based on Gender and age differences. Keywords: marital intimacy, gender, age, intimacy level, couple

Solar wind magnetic holes can cross the bow shock and enter the magnetosheath

Solar wind magnetic holes are localized depressions of the magnetic field strength, on timescales of seconds to minutes. We use Cluster multipoint measurements to identify 26 magnetic holes which are observed just upstream of the bow shock and, a short time later, downstream in the magnetosheath, thus showing that they can penetrate the bow shock and enter the magnetosheath. For two magnetic holes, we show that the relation between upstream and downstream properties of the magnetic holes are well described by the MHD (magnetohydrodynamic) Rankine&ndash;Hugoniot (RH) jump conditions. We also present a small statistical investigation of the correlation between upstream and downstream observations of some properties of the magnetic holes. The temporal scale size and magnetic field rotation across the magnetic holes are very similar for the upstream and downstream observations, while the depth of the magnetic holes varies more. The results are consistent with the interpretation that magnetic holes in Earth's and Mercury's magnetosheath are of solar wind origin, as has previously been suggested. Since the solar wind magnetic holes can enter the magnetosheath, they may also interact with the magnetopause, representing a new type of localized solar wind&ndash;magnetosphere interaction. &nbsp;</p

A Single Deformed Bow Shock for Titan-Saturn System

During periods of high solar wind pressure, Saturn's bow shock is pushed inside Titan's orbit exposing the moon and its ionosphere to the solar wind. The Cassini spacecraft's T96 encounter with Titan occurred during such a period and showed evidence for shocks associated with Saturn and Titan. It also revealed the presence of two foreshocks: one prior to the closest approach (foreshock 1) and one after (foreshock 2). Using electromagnetic hybrid (kinetic ions and fluid electrons) simulations and Cassini observations, we show that the origin of foreshock 1 is tied to the formation of a single deformed bow shock for the Titan‐Saturn system. We also report the observations of a structure in foreshock 1 with properties consistent with those of spontaneous hot flow anomalies formed in the simulations and previously observed at Earth, Venus, and Mars. The results of hybrid simulations also show the generation of oblique fast magnetosonic waves upstream of the outbound Titan bow shock in agreement with the observations of large‐amplitude magnetosonic pulsations in foreshock 2. We also discuss the implications of a single deformed bow shock for new particle acceleration mechanisms and also Saturn's magnetopause and magnetosphere
