Measurement and Improvement of Information Security Culture

Remote IT based operations of offshore oil and gas installations are increasing in the North Sea. The motivation for remote operation is increased income, cost reductions and more efficient support. The technology used to support operations is changing from proprietary closed systems to standardised IT systems built on PC’s and MS Windows connected to both internal networks and the Internet. In addition the operations and management of the oil and gas fields are increasingly being performed by a network of firms that functions as a virtual organization. The network organizations and the increased vulnerabilities create the need for improved information security. Our hypothesis is that an important contribution to improved information security (IS) is improved IS culture and improved communication during operations and incident handling. IS culture should be explicitly focused, and actions should be taken to improve IS culture from a purely rule based culture to an ideal learning culture. We have suggested a method called CheckIT consisting of a questionnaire and a process to improve IS culture based on group discussions. The questionnaire consists of questions and suggested answers based on denial based culture, rule based culture and the ideal learning culture, to enable the participants to explore their culture and identify areas to be improved.

An improved analytical model for the switched reluctance motor

In analytical modeling of the switched reluctance (SR) machine, current is often chosen as the state variable, although flux-linkage provides a simpler and more efficient choice. Furthermore, it is typically the case that mutual inductance is neglected. In this paper, a new analytic formulation is presented that uses flux-linkage as the state variable and in which mutual coupling between phases is also represented. In addition, the paper presents an approach to determining the parameters of the flux-linkage curves of the machine that result in a better fit with measured laboratory data. Using the proposed approach, the simulated machine performance for a 12/8 SR motor is shown to compare favorably with experimental results measured in the laboratory.
Polarization Splitter-Rotator Based on Multimode Waveguide Grating

We demonstrate a polarization splitter rotator (PSR) based on multimode waveguide grating (MWG) on a silicon-on-insulator (SOI) platform. Bloch mode hybridization in mini-stopband is exploited to achieve high polarization conversion efficiency. The fabricated device yields a high extinction ratio of > 53 dB and > 31 dB, low crosstalk of < −26.4 dB and < −40 dB for the injected TE0 and TM0 mode, with average insertion loss of 1.2 dB and 1.5 dB in the wavelength regime 1552 nm–1562 nm. Such a device shows great design flexibility and an easy fabrication process, serving as a good candidate in integrated polarization diversity circuits, especially for applications requiring spectra manipulation. Additionally, the polarization conversion approach provides opportunities to develop novel polarization management devices.
Tornado warning trade-offs: evaluating choices for visually communicating risk

AbstractRecent improvements in weather observation and monitoring have increased the precision of tornado warnings. The National Weather Service currently issues storm-based tornado warnings, and even more geographically specific warnings that include probability information are under development. At the same time, the widespread proliferation of smartphone and mobile computing technology supports the rapid dissemination of graphical weather warning information. Some broadcasters and private companies have already begun using probabilistic-style tornado warning graphics. However, the development of these new types of warnings has occurred with limited research on how users interpret probabilistic visualizations.This study begins filling this void by examining responses to color scheme and relative position using probabilistic tornado warning designs. A survey of university students is used to measure the level of perceived fear and likelihood of protective action for a series of hypothetical warning scena.
Matching laboratory courses to engineering activities

After presenting the various distinct types of laboratory activity, the authors describe in some detail how they have modified a sophomore circuits laboratory course. Traditionally, this course has engaged students in rediscovering what they already should have learned in their lecture course. The authors have made the experience into one of circuit design evaluation, where the students are asked to explore the differences between practical realities and theoretical possibilities by evaluating the performance of their own designs. They outline some of their exercises to clarify the distinction they are making from the traditional approach, and present evidence of student interest.
Effects of Main Swirl Direction on High -g Combustion

The use of high -g combustors promises to greatly decrease burner size and improve cost, weight, efficiency and durability of turbine engines . The latest design of the Ultra -Compact Combustor (UCC) is one such technology that utilizes swir l enhanced combustion at up to 10, 000 g’s . Recessed cavi ties create areas of flame stabilization and make possible the very low residence times experienced by this combustor. The use of turning vane passages simulates combustion in a turbine stator stage. Tests conducted at the Air Force Research Laboratory’s (AFRL) Atmospheric Pressure Combustion Research Center (APCRC) have studied the effect of the main swirl direction in the UCC using both standard and coal derived jet fuels. This research gives insight into the physics of the burner ’s operation.

The results suggested that there are distinctive characteristics between these two professionals profiles.
Maximum, Minimum, and Daily Air Temperature Range in Orchards: What Do Observations Reveal?

This study was designed to better understand vegetation’s impact on air maximum (Tmax), minimum (Tmin), and daily temperature range (DTR), as well as seasonality and variability. We selected a flat, under synoptic-scale, northern Serbian region with an operational network of automated weather stations (AWS) for the study. Data were collected directly from the eighteen AWSs placed in the orchard canopy during 2013–2018. Meteorological data, plant phenological data in the form of the BBCH scale, and orchards’ soil characteristics data were collected. Environmental factors influencing the temperature were classified as static (slow or unchangeable) and dynamic (fast-changing). The impact of both factors on maximum, minimum, and daily temperature range and its variability were analyzed. Results show that static factors (like soil texture) affect the annual variation of Tmax, Tmin, and DTR rather than its variability over the season. The dynamic factors, mainly coming from the plant’s phenology, substantially affected the seasonal variability of these variables. Studies like this suffer from missing data and sparse spatial coverage by the AWS network. Therefore, the alternatives of orchard micrometeorological data, nearest climatological station, and ERA5-Land reanalysis data are tested. Both data sets showcased limitations in their applicability, while reanalysis data deviated more from the in-situ measurements, both seasonally and regionally.
Temperature dependence of hole drift mobility in high‐purity single‐crystal CVD diamond

Hole transport properties in high‐purity single crystal CVD diamond samples were studied using the time of flight technique with optical excitation of the carriers. The measurements were taken at different temperatures in the interval 80–470 K. By varying the intensity of the optical excitation over several orders of magnitude, measurements at different carrier concentrations have been performed. In this way, measurements have been made both in the space charge limited and non space charge limited regimes, with consistent results. The temperature dependence of the low‐field hole drift mobility shows a Tα dependence with α ≈ –1.5, below 350 K. This indicates that acoustic phonon scattering is the dominant scattering mechanism and a very low concentration of ionized impurities in this material. (© 2005 WILEY‐VCH Verlag GmbH & Co.

The Health Benefits of Sexual Expression

Abstract Objective Sexual activity is a fundamental human function with short-term and long-term emotional, social, and physical benefits. Yet within healthcare, sexuality has been marginalized and many HCPs are unaware of its beneficial implications for immediate and long-term health. Methods To challenge this assumption we combined the data that already had been collected by the authors with an extensive search of articles on the various health benefits of sexual activity. The results of this process are displayed according to short-term, intermediate-term, and long-term benefits with some explanation about potential causal relationships. Results For the time being, it cannot yet be proved that “good sex promotes good health” since good health also favors good sex. Conclusions Despite lacking such convincing evidence, the article concludes with recommendations for the relevant professions. The balance of research supports that sexuality anyhow deserves greater attention among HCPs and that sexuality research needs better integration within health research.
A Normalized HLD (HLDN) Tool for Optimal Salt-Concentration Prediction of Microemulsions

Optimal condition-based microemulsion is key to achieving great efficiency in oil removal. One useful empirical equation to predict an optimal condition is a hydrophilic–lipophilic deviation (HLD). However, the K constants of each surfactant should be the same to combine the HLD equations for the mixed surfactant. Recently, a normalized hydrophilic-lipophilic deviation (HLDN) was presented to avoid this limitation. This work sought to determine the phase behaviors and predict the optimal salt concentrations, using HLDN for the mixed surfactant. Sodium dihexyl sulfosuccinate (SDHS) as an anionic surfactant, and alcohol alkyl polyglycol ether (AAE(6EO4PO)) as a nonionic surfactant, were both investigated. Alkanes and diesel were used as a model oil. The results showed that AAE(6EO4PO) enforced both the hydrophilic and the hydrophobic characteristics. The Winsor Type I-III transition was influenced by the ethylene oxide, while the propylene oxide presence affected the Winsor Type III-II inversion. For the HLDN equation, the average interaction term was 1.82 ± 0.86, which markedly showed a strong correlation with the fraction of nonionic surfactant in the mixed systems. The predicted optimal salt concentrations using HLDN of SDHS-AAE(6EO4PO) in the diesel systems were close to the experimental results, with an error of <10% that is significantly beneficial due to the shorter time required for optimal determination.
Behavior Based Multi Robot Formations with Active Obstacle Avoidance Based on Switching Control Strategy

This paper considers the problem of formation control and obstacle avoidance for a group of non-holonomic mobile robots in a leader referenced model based on reactive switching control strategy. Three important issues related to the multi robot formation namely distributed formation control framework, dynamic role switching algorithm and real time implementations are investigated. The switching control strategy combines together formation planning, navigation and active obstacle avoidance in a layered control framework composed of functional behaviors based on the relative motion states of the robots employed in the group. Dynamic role switching mechanism incorporated in this work to tackles the problem of obstacle avoidance in the follower path. The proposed approach is validated through laboratory experiments using commercially available robot research platforms and the results obtained are discussed.
Small to Medium Contractor Contingency and Assumption of Risk

This paper is the result of an investigation into the use of contingency in smaller construction firms. It summarizes recent literature classifying construction contract risks and mitigation measures. Eight major classifications are used to organize the types of risk found in the literature. The risks are described in detail with associated risk mitigation strategies. Risk modeling techniques are briefly reviewed for their contribution to the risk categorization and contingency estimating. After reviewing the researcher's concepts of risk management in the literature, interviews were conducted with estimators and/or construction managers involved in the bidding process at 12 small to medium construction firms. The purpose of the interviews was to investigate the current risk management practices of small and medium size construction firms. The times when smaller companies used contingency had specific interest for the research. The literature findings were compared with important risk factors identified f.
Dynamic modulation of slow light by electro-optic effect in photonic crystal coupled resonator optical waveguide

A novel structure of photonic crystal coupled resonator optical waveguide (PC-CROW) with elliptical rod around cavity is proposed to realize compact, high sensitivity modulated and high-performance buffering application. By adjusting the long axis and short axis of the elliptical rods, the slow light and buffer performance of PC-CROW are optimized. As ae=0.42a, be=0.20a, the group velocity is below 2.3053×10-4c, simultaneously, the buffer capacity C and delay time Ts reach the optimum value. Then the dynamic modulation of the slow light and buffer performance based on this optimized structure has been discussed systematically. The guided mode shifts linearly to short wavelength and delay time decreases exponentially as the external modulated voltage increases. And the modulation sensitivities are about 3.0nm/mV and 0.467ns/mV, respectively. These results show that the proposed structure has considerable potential for optical buffering application. hese results show that the proposed structure has considerable potential for optical buffering application.
An improvement of time-varying interference mitigation techniques through collaborative reception schemes

High power time-varying interference or jamming can severely disrupt wireless communication. Therefore, the technique of relevant interference mitigation is needed. Cooperative communication technique can organize a group of single-antenna systems in the same area at different locations as a distributed antenna array. Thus it can approximately achieve the diversity gain of regular multiple-antenna system. This paper is focused on cooperative communication for time-varying interference mitigation. Since some of traditional collaborative reception techniques have the constraint of requiring accurate estimation of SNR, an improvement of time-varying interference mitigation technique based on log-likelihood ratio (LLR) and jammer cancellation is proposed. The simulation results demonstrate that this new improved method enables communication in much more severe interference conditions.
Microfluidic Detection of Waterborne Pathogen through Light Scattering of Particle Immunoassays

This dissertation focused on detecting waterborne pathogens in a microfluidic biosensing system which enables point-of-care, real-time monitoring. Within this framework, I have been addressing three objectives. The first objective was to enhance mixing of particles in a microfluidic device. To this end, SDS (sodium dodecyl sulfate) or Tween 80 (polyethylene sorbitol ester) was added to the antibody-conjugated polystyrene microparticle suspension. Both surfactants showed non-specific binding (with SDS) or very poor diffusion (with Tween 80). As an alternative approach, highly carboxylated polystyrene microparticles showed very low non-specific binding comparable to that with Tween 80 and good diffusional mixing equivalent to that with SDS. This work was published in Appendix A (© 2008 Elsevier). The second objective was to detect E. coli K-12 using the microfluidic-based system with low detection limit in Appendix B (© 2008 Elsevier). This method was essentially one-step and requires no sample pre-treatment or cell culturing. Conventional immunoassay using polyclonal antibody detects not only viable cells, but also dead cell and free antigens. In order to reduce false positive signal originated from dead cells and free antigens, target solution was washed three times. The detection limit was as low as 40 cfu ml or 4 cfu per device (viable cells only), or <10 cfu ml or <1 cfu per device (including dead cells and free antigens). Our final objective was to develop real-time, high sensitive method for detecting waterborne pathogens in a water distribution system in Appendix C. Detection of Escherichia coli (E. coli) in a single straight pipe was demonstrated using a microfluidic
Rapid Identification of the Chemical Components of Ilex rotunda Thunb Using UPLC-Q-TOF-MS/MS

Ilicis Rotundae Cortex (IRC) consists of the bark of Ilex rotunda Thunb, and its chemical constituents mainly include flavonoid glycosides, phenols, and triterpenoid saponins. In this study, a preliminary analysis was performed to identify and obtain the chemical components from IRC to better control the quality of the medicinal materials and provide a chemical basis for the study of the efficacy of the active components. Simple and efficient sample pretreatment and ultrasonic-assisted extraction methods were used to analyze the mass spectrum fragments and fracture modes in the anion mode by UPLC-Q-TOF-MS/MS. Using a two-step strategy, the neutral loss, diagnostic ions, and characteristic fragments were studied to screen diverse skeletons and substitutions, and the possible compounds were identified by comparison with databases. The representative compounds were compared with the standard, and the mass spectrogram was found to match perfectly. Thus, our findings reveal that this method is feasible and reliable and can be used to analyze the chemical components of IRC. We identified 105 compounds, including 22 triterpenoid saponins, 15 chlorogenic acids, 33 phenylpropanoids and phenylpropanosides, 3 iridoids, 1 flavonoid, 10 lignans, 12 glycosides, and 9 other compounds. This method lays the foundation for further elucidating the pharmacodynamics of IRC and provides a practical method for the identification of IRC.
Serious Harm Reduction Strategies Indirectly Affects the Relationship between Explicit Drinking Identity and Hazardous Drinking in College Males

ABSTRACT College male alcohol use continues to be a topic of interest due to its prevalence and the nature of consequences reported by this group. Research concerned with prevention and intervention efforts has focused on alcohol protective behavioral strategies (PBS) and the subtypes (i.e., manner of drinking, stopping/limiting drinking, and serious harm reduction), as a promising approach to reduce harm associated with drinking. Past research indicates college males are less likely than their female peers to use PBS. Currently, little research has explored whether explicit drinking identity may be associated with college males’ relative lack of PBS use. The current study examined the indirect association of explicit drinking identity with alcohol outcomes through the relation with PBS subtypes. This study utilized a national sample of 599 college males (M = 22.52, SD = 2.02) who completed measures of drinking identity, PBS use, and alcohol outcomes (i.e., negative consequences and hazardous use). Results indicated a positive association between drinking identity and alcohol outcomes (i.e., hazardous alcohol use and alcohol-related negative consequences). The relationship between drinking identity and hazardous alcohol use was partially explained by less use of serious harm reduction-PBS strategies. Research and clinical practice implications are discussed.
