Theoretical analysis of the electrical aspects of the basic electro-impulse problem in aircraft de-icing applications

A method of modelling a system consisting of a cylindrical coil with its axis perpendicular to a metal plate of finite thickness, and a simple electrical circuit for producing a transient current in the coil, is discussed in the context of using such a system for de-icing aircraft surfaces. A transmission line model of the coil and metal plate is developed as the heart of the system model. It is shown that this transmission model is central to calculation of the coil impedance, the coil current, the magnetic fields established on the surfaces of the metal plate, and the resultant total force between the coil and the plate. FORTRAN algorithms were developed for numerical calculation of each of these quantities, and the algorithms were applied to an experimental prototype system in which these quantities had been measured. Good agreement is seen to exist between the predicted and measured results.

Potential of a New Lunar Surface Radiator Concept for Hot Lunar Thermal Environments

The optimum radiator configuration in hot lunar thermal environments is one in which the radiator is parallel to the ground and has no view to the hot lunar surface. However, typical spacecraft configurations have limited real estate available for top-mounted radiators, resulting in a desire to use the spacecraft s vertically oriented sides. Vertically oriented, flat panel radiators will have a large view factor to the lunar surface, and thus will be subjected to significant incident lunar infrared heat. Consequently, radiator fluid temperatures will need to exceed approx.325 K (assuming standard spacecraft radiator optical properties) in order to provide positive heat rejection at lunar noon. Such temperatures are too high for crewed spacecraft applications in which a heat pump is to be avoided. A recent study of vertically oriented radiator configurations subjected to lunar noon thermal environments led to the discovery of a novel radiator concept that yielded positive heat rejection at lower fluid temperatures. This radiator configuration, called the Upright Lunar Terrain Radiator Assembly (ULTRA), has exhibited superior performance to all previously analyzed concepts in terms of heat rejection in the lunar noon thermal environment. A key benefit of the ULTRA is the absence of louvers or other moving parts and its simple geometry. Analysis of the ULTRA for a lunar extravehicular activity (EVA) portable life support system (PLSS) is shown to provide moderate heat rejection, on average, at all solar incident angles assuming an average radiator temperature of 294 K, whereas prior concepts exhibited insignificant heat rejection or heat absorption at higher incident angles. The performance of the ULTRA for a lunar lander is also discussed and compared to the performance of a vertically oriented, flat panel radiator at various lunar latitudes.
Via DREEM, Dream of Medical Students Come True

It's important to assess the educational environment regularly because of its impact on the students' outcomes. It is a descriptive cross-sectional study to evaluate students' perception of the learning environment among undergraduate students in the Faculty of Medicine, University of Andalas (FMUA) by using Dundee Ready Educational Environment Measure (DREEM). Total of 403 students from 1st till 7th semester has participated in this study. The interpretation of the overall DREEM score in each batch was more positive and negative. The subscales of DREEM (students' perception of learning, students' perception of teachers, students' academic self-perception, students' perception of atmosphere, students' social-self-perception) were perceived good. Both genders perceive the learning environment as more positive than negative. The finding was similar to finding in the teacher-centered curriculum while FMUA applied a student-centered curriculum. It could be affected by the study's limitations. Thus, the faculty needs to evaluate the learning process and adjust the environment to suit the curriculum.
Modeling IVHSEmission Impacts Volume II: Assessement Of The Caline 4 Line Source Dispersion Model

This report assesses the ability of the emission estimating algorithms contained in version 4 of the CALINE line source dispersion model developed by Caltrans (CALINE 4) to accurately predict carbon monoxide emissions from a fleet of motor vehicles. The CALINE 4 model contains algorithms that predict carbon monoxide emissions from discrete modal events of idle, cruise, acceleration, and deceleration. The modified CALINE 4 model algorithms are used to predict CO impacts of an applied intelligent vehicle and highway system concept, automatic vehicle identification applied to electronic tolling operations. The analyses show that electronic tolling in place of conventional toll plazas offers significant CO reductions under three different operating scenarios. The authors conclude that under certain applications, Intelligent Vehicle Highway Systems (IVHS) technologies can be beneficial to air quality.
Technology Shocks and Predictable Minsky Cycles

Big technological improvements in a new, secondary sector lead to a period of excitement about the future prospects of the overall economy, generating boom-bust dynamics propagating through credit markets. Increased future capital prices relax collateral constraints today, leading to a boom before the realization of the shock. But reallocation of capital toward the secondary sector when the shock hits leads to a bust going forward. These cycles are perfectly foreseen in our model, making them markedly different from the typical narrative about unexpected financial shocks used to explain crises. Our dynamics obtain without a departure from rational expectations. In fact, these cycles echo Minsky’s original narrative for financial cycles, according to which “financial trauma occur as normal functioning events in a capitalistic economy. ” (Minsky, 1980, p. 21).
Annual Average Daily Traffic Prediction Model for County Roads

A traffic prediction model that incorporates relevant demographic variables for county roads was developed. Field traffic data were collected from 40 out of 92 counties in Indiana. The selection of a county was based on population, state highway mileage, per capita income, and the presence of interstate highways. Three to four automatic traffic counters were installed in each selected county. Most counters installed on the selected road sections were based on the standard 48-hour traffic counts. Then, the obtained average daily traffic was converted to annual average daily traffic by means of adjustment factors. Multiple regression analysis was conducted to develop the model. There were quantitative and qualitative predictor variables used in the model development. To validate the developed model, additional field traffic data were collected from eight randomly selected counties. The accuracy measures of the validation showed the high accuracy of the model. The statistical analyses also found that the independent variables employed in the model were statistically significant. The number of independent variables included in the model was kept to a minimum.
Adoption of learning innovations within UK universities : validating an extended and modified UTAUT model

Rapid changes affecting the whole world did not spare universities as they face a lot of challenges and pressures. The national and international competition between universities is gaining more momentum. Many universities are experimenting with and adopting different innovative approaches and technologies an attempt to enhance their education and services to secure more students and funds. The topic of innovation received quite a lot of attention in recent years. Despite the growing attention to innovation in services, however, little attention has been given to innovations and their diffusion in universities. A number of theories and models were developed and validated in different contexts to help explain the adoption of innovations and technologies. However, such theories and models did not lead to a significantly better understanding of what leads to the adoption and diffusion of innovations within universities. Based on well-established adoption theories and models, this study proposed a new model that helps explain the adoption of learning innovations within UK universities. Two education-related constructs expected to influence innovation adoption were also developed and tested. Using a quantitative survey approach and utilising a questionnaire instrument, data was collected from staff members from a number of UK universities. Analysis of data showed that the proposed model explains up to 30%, and in some cases more, of the variance in the innovation adoption behaviour of staff members in UK universities. Model testing and development resulted in some interesting new relationships and influences that had not previously reported. For instance, the students‘ requirements and expectations constructs proposed was found to influence the intention as well as the use of innovations. Practical recommendations to help UK universities in diffusing innovations are also discussed in detail at the end of this study, which concludes by emphasising the importance of nurturing staff members to encourage and promote innovation in learning.
System Risk Assessment and Allocation in Conceptual Design

As aerospace systems continue to evolve in addressing newer challenges in air and space transportation, there exists a heightened priority for significant improvement in system performance, cost effectiveness, reliability, and safety. Tools, which synthesize multidisciplinary integration, probabilistic analysis, and optimization, are needed to facilitate design decisions allowing trade-offs between cost and reliability. This study investigates tools for probabilistic analysis and probabilistic optimization in the multidisciplinary design of aerospace systems. A probabilistic optimization methodology is demonstrated for the low-fidelity design of a reusable launch vehicle at two levels, a global geometry design and a local tank design. Probabilistic analysis is performed on a high fidelity analysis of a Navy missile system. Furthermore, decoupling strategies are introduced to reduce the computational effort required for multidisciplinary systems with feedback coupling.
Water quality and accelerated winter growth of European catfish using an enclosed recirculating system

Aquaculture of the European catfish Silurus glanis is impeded by the slow rate of growth at ambient water temperatures below 10°C, which are encountered during the winter months in many regions of Europe (such as central France). In an effort to increase water temperatures over this period, fish were held in an enclosed housing where the water quality was maintained using a low‐cost treatment plant. For comparison, some fish were held in a separate system that was not enclosed and where water treatment took place in an adjacent earth‐lined pond. Both systems were able to maintain good water quality during the winter months but the recirculating system achieved significantly higher water temperatures and rates of fish growth.
Approximate Design Method for Single Stage Pulse Tube Refrigerators

An approximate design method is presented for the design of a single stage Stirling type pulse tube refrigerator. The design method begins from a defined cooling power, operating temperature, average and dynamic pressure, and frequency. Using a combination of phasor analysis, approximate correlations derived from extensive use of REGEN3.2, a few ‘rules of thumb,’ and available models for inertance tubes, a process is presented to define appropriate geometries for the regenerator, pulse tube and inertance tube components. In addition, specifications for the acoustic power and phase between the pressure and flow required from the compressor are defined. The process enables an appreciation of the primary physical parameters operating within the pulse tube refrigerator, but relies on approximate values for the combined loss mechanisms. The defined geometries can provide both a useful starting point, and a sanity check, for more sophisticated design methodologies.
A new characterization tool for vertical profile measurement of high-aspect-ratio microstructures

We have developed a system for the measurement of the inner profile of high-aspect-ratio microstructures. This system uses silicon micro-probes with a sharp tip at their end and an integrated piezoresistive force sensor. The probes are 1 mm long with a cross-sectional area of 20 × 20 μm2, which allowed characterization of narrow and deep micro-holes having a radius as small as 40 μm. The measurement procedure utilizes an original algorithm, which prevents it from many unwanted phenomena. It is entirely automated by using a computer control.
Adaptive sliding-mode neuro-fuzzy control of the sensorless induction motor drive with MRAS CC estimator

In the paper a model reference adaptive sliding-mode control using on-line trained fuzzy neural network is applied to the sensorless induction motor drive system with MRAS type speed estimator. In this control structure adaptive sliding-mode neuro-fuzzy controller (ASNFC) is used as a speed controller, in the direct field oriented control structure. Connective weights of this controller are trained on-line according to the error between the actual speed of the drive and the reference model output signal. The rotor flux and speed of the vector controlled induction motor are estimated using the novel MRASCCestimator. Simulation results are verified in experimental tests.
Evaluation of antimicrobial and antioxidant attributes of Tanzanian honey from two agro-ecological areas

Luvanda FT, Lyimo ME. 2018. Evaluation of antimicrobial and antioxidant attributes of Tanzanian honey from two agroecological areas. Biofarmasi J Nat Prod Biochem 16: 69-82. In order to appraise the characteristic of Tanzanian honey based on antioxidant attributes and antimicrobial activity on bacteria and fungi in relation to its physicochemical attributes, the study was conducted. The examined honey was sampled from two kinds of bees namely stinging and stingless honey bees and was gathered from the western area (Tabora and Shinyanga) and the central area (Singida and Dodoma). They were examined for their antimicrobial activity, anti-oxidant attributes (total phenol, vitamin C) and physicochemical attributes of pH, color, pH, sugar, and minerals. 54 % of tested honey samples inhibited microbial growth but the remaining 46% did not inhibit the growth. Microbial impediment areas range from 8.5 to 14.16 mm (stinging honey bee) and 10.56-15.13 mm (stingless honey bee). Honey yielded by stinging honey bee in the cities of Shinyanga, Bukombe, and Nzega and the cities of Singida and Issuna is more effective in impeding microbial growth than that of other cities. Candida albicans is more sensitive (23.1%) to honey of stingless honey bee, followed by Staphylococcus saprophyticus (33%), Salmonella typhi (32%), Escherichia coli (19.2%) and Aspergillus flavus (16.0%). The substance of antioxidant, total phenol and vitamin C in honey of stingless honey bee were importantly (P <0.05) higher than that of honey of stinging honey bee. Antioxidants (FRAP) ranged from 322.16-973.57 µMFe (II) /100g, total phenols was from 13.87-33.55 mg /100g and vitamin C was from 2.54-10.99 mg /100. At pH value, there was no substantial dissimilarity (P> 0.05) between the two samples of honey. Potassium possesses the highest value while Zn possesses the lowest value in samples of honey of stinging and stingless honey bee. The gradation color of honey of stingless honey bee ranged from extra light amber-light amber while that of honey of stinging bee ranged from white water-light amber. There was a positive and substantial correlation (P <0.001) between the color of honey, antioxidants, total phenol, and mineral substance. Stingless honey bee's honey from the western region is superior to stinging honey bee's honey in antioxidant and antimicrobial attributes and therefore is prompted to be utilized as a valuable diet product, preventive and curative medicine.
HVOTL Structures and Residential Property Investments in Suburban Lagos,Nigeria

High Voltage Overhead Transmission Lines (HVOTLs) otherwise referred to as powerlines, have been ascertained to influence diminution in property value. This study epicenters on the impact of power-lines on the rent of residential properties in suburban Lagos. Questionnaires were distributed to registered Estate Surveying firms, residents within 200m of a I Okm double tracked power-line in Alimosho, Lagos while an indepth interview of the manager and field officers of the Alimosho PHCN sub-station was conducted. Averagely, a response rate of 66.5% was achieved and collated data were analysed accordingly. Findings revealed that the rents payable for homes within 1OOm proximity to the power line did not suffer value diminution. Finally, the study recommended the PHCN to call to order, all residents breaching the 25m ROW in suburban Lagos, to foster environmental decorum and also retain the null effect of power-lines on rents in the neighbourhood as the suburb gradually merges into the metropolis.

Joined-Up Governance in Australia: How the Past Can Inform the Future

Joined-up enterprises have become a cornerstone of the institutional architecture to facilitate closer linkages within and between departments and across sectors. Some of these initiatives are now mainstream enterprises, while others struggled to gain purchase or effect. Since the future is likely to be characterized by an ongoing emphasis on joined-up initiatives, an assessment of past efforts can provide a valuable backdrop for the development of new approaches and the fine tuning of existing ones. Drawing on ten years of research data, this article tracks the ebbs and flows of joined-up or integrated practice in Queensland. In doing so, it examines the drivers for integration, preferred models, and the language used to engender change. It also assesses what has worked and why and whether integrated reform has been sustained. Based on these insights, an extended integration framework is presented, which will assist those responsible for the design, monitoring, and evaluation of joined-up processes.
Steps to the future : fresh thinking on the management of IT-based organizational transformation

From the Publisher: In this thought-provoking compendium, top IT experts from around the world analyze why transformation efforts built around IT often fail, and share provocative and practical methods for ensuring that IT lives up to its promise. Writing for both IT and general business managers, they zero in on the management competencies required for successful, sustainable change, incorporating case studies and cutting-edge research findings to pinpoint the failings of traditional IT management approaches such as strategic alignment and business process reengineering. They persuasively argue for the integration of the core business unit and the IT function, advocate a new role for IT professionals, stress the importance of managing outcomes rather than process, and provide practical guidelines for turning new ideas into new management practices. Presenting novel and stimulating ways of thinking about the dynamics of change, Steps to the Future includes a challenging vision of what organizations of the future will need to compete - and helps managers, executives, and consultants meet the challenge with a radically new, incremental approach to managing the process.
Reliable Control for Linear Dynamic Systems with Time-varying Delays and Randomly Occurring Disturbances

In this paper, the problem of reliable control of linear systems with time-varying delays, randomly occurring disturbances, and actuator failures is investigated. It is assumed that actuator failures occur when disturbances affect to the systems. Firstly, by using a suitable Lyapunov-Krasovskii functional and some recent techniques such as Wirtinger-based integral inequality and reciprocally convex approach, stabilization criterion for nominal systems with time-varying delays is derived. Secondly, the proposed method is extended to the reliable H∞ controller design for linear dynamic systems with time-varying delays, randomly occurring disturbances, and actuator failures. Since nonlinear matrix inequalities (NLMIs) are involved in proposed results, the cone complementarity algorithm will be introduced. Finally, two numerical examples are included to show the effectiveness of the proposed criteria.
