High altitude solar power platform

Solar power is a preeminent alternative to conventional aircraft propulsion. With the continued advances in solar cells, fuel cells, and composite materials technology, the solar powered airplane is no longer a simple curiosity constrained to flights of several feet in altitude or minutes of duration. A high altitude solar powered platform (HASPP) has several potential missions, including communications and agriculture. In remote areas, a HASPP could be used as a communication link. In large farming areas, a HASPP could perform remote sensing of crops. The impact of HASPP in continuous flight for one year on agricultural monitoring mission is presented. This mission provides farmers with near real-time data twice daily from an altitude which allows excellant resolution on water conditions, crop diseases, and insect infestation. Accurate, timely data will enable farmers to increase their yield and efficiency. A design for HASPP for the foregoing mission is presented. In the design power derived from solar cells covering the wings is used for propulsion, avionics, and sensors. Excess power produced midday will be stored in fuel cells for use at night to maintain altitude and course.

Behaviour of Powders from Different Geldart Groups in a Rotating Drum

The flow behaviour of particulate materials in rotating drums is typically characterised by seven distinct regimes. However, inspection of the literature suggests that these regimes have been assigned on the basis of observations of Geldart Group B and D particles only. In this paper we extend earlier work and report results obtained with Geldart Groups, A, B, and D, in a drum 130 mm in diameter and 25 mm long; we also comment on the behaviour of a Group C powder. A new instrument has been used to characterise and quantify gross particle movement via the variance of a signal from a load cell that responds to changes in the position of the centre of mass of the material in the drum. The experimental programme primarily addressed the regimes associated with relatively low rotation rates, where particle movement is either by discrete avalanches or by a continuous flow in which the particles roll or cascade across a static bed. The results of work in progress show that Geldart Group B and D powders exhibited similar behaviour, and as the rotation rate increased, the variance of the load cell signal decreased. The variances measured for a Group A powder and a powder provisionally identified as Geldart Group C, increased with increasing rotation rate.
Consumer Response to Logo Shape Redesign: The Influence of Brand Commitment

This dissertation examines consumer response to one aspect of logo redesign: shape. Relatively little research has focused exclusively on logos and even less attention has been given to logo redesign. Reaction to change in logo shape is hypothesized to be a function of the degree of change (from incremental to considerable) and the level of commitment (from strong to weak) a consumer has towards the underlying brand. Consumers who are strongly committed to a brand will more negatively evaluate redesigned logos and have more negative attitude toward the brand. Conversely, consumers less committed to a brand will more positively evaluate redesigned logos and have more positive attitude toward the brand. Four experimental studies are discussed. The first three studies used athletic shoe logos as stimuli. The fourth study extended generalizability by replicating the effects of Study Three with bottled water brands and considered a number of mediating variables. Results fully support the concept of brand commitment moderating logo evaluation and change in brand attitude. The mediating variables were found to not influence the main effect of brand commitment on logo evaluation and change in brand attitude.
Ultra Wideband Miniature Microstrip Patch Antenna with Defected Ground Notches

The defected ground notches DGN for microstrip patch antenna and its effects on antenna performance have been studied using HFSS simulator. Different patch shapes: square, triangular-rectangular and circular have been supposed. The DGN has been suggested by reducing the length of antenna ground plane and making different shapes of notches at the edges of the proposed ground. The obtained results indicates that the antenna ground of length reduction with three, one and three notches gives respectively an impedance bandwidth from 3.42-17.45 GHz (134% w.r.to centre frequency), 2.33-14.63 GHz (145%) and 3.31-16.13 GHz (131%) for square, triangular-rectangular and circular patches. Also a size reduction of 83.5%, for square and circular patches and 82.5% for triangular-rectangular patch are achieved at resonance frequency of 4.05 GHz and 4.5 GHz respectively compared with those antennas having the same design and operating at the same resonance frequencies but without DGN.
Tracking hackers on IRC

Few hackers are motivated purely by knowledge, science and curiosity. Hackers continue to break into systems long after they become familiar with the technology. Instead, many continue to hack simply because of the social status it brings. For many, hacking is a social activity. Hackers meet online to discuss the latest hacking tools, their hacking conquests, and their personal lives. To be truly effective, system administrator and security professionals must become familiar with the social culture in which hackers dwell.
Cloud Computing: Methodology, Systems, and Applications

Cloud computing has created a shift from the use of physical hardware and locally managed software-enabled platforms to that of virtualized cloud-hosted services. Cloud assembles large networks of virtual services, including hardware (CPU, storage, and network) and software resources (databases, message queuing systems, monitoring systems, and load-balancers). As Cloud continues to revolutionize applications in academia, industry, government, and many other fields, the transition to this efficient and flexible platform presents serious challenges at both theoretical and practical levelsones that will often require new approaches and practices in all areas. Comprehensive and timely, Cloud Computing: Methodology, Systems, and Applications summarizes progress in state-of-the-art research and offers step-by-step instruction on how to implement it. Summarizes Cloud Developments, Identifies Research Challenges, and Outlines Future Directions Ideal for a broad audience that includes researchers, engineers, IT professionals, and graduate students, this book is designed in three sections: Fundamentals of Cloud Computing: Concept, Methodology, and Overview Cloud Computing Functionalities and Provisioning Case Studies, Applications, and Future Directions It addresses the obvious technical aspects of using Cloud but goes beyond, exploring the cultural/social and regulatory/legal challenges that are quickly coming to the forefront of discussion.

Using shredded waste tires as a lightweight fill material for road subgrades. Summary report

Waste tires have been a disposal problem in the past and are continuing to accumulate throughout the U.S. today. Using shredded waste tires as a lightweight fill material for road construction has proven to be a beneficial use of this waste product. Shredded tires have been used as a lightweight fill material in Minnesota, Colorado, Oregon, Washington, North Carolina, Virginia, and Wisconsin. Minnesota began using shredded tires as a lightweight fill material in 1985 on logging roads through areas with weak soils. This report documents seven sites in Minnesota that used shredded waste tires as lightweight fill. Shredded tires were proven to be a viable form of lightweight fill because they are relatively lightweight, inexpensive and non-biodegradable. In general, the material is very elastic, is very porous, contains good vibration damping properties, and is easily compacted. On the downside, shredded tires lack set design standards and specifications. The report also documents some of the environmental testing completed on shredded tires to date.
Trend and predictors of unsafe child stool disposal in Ethiopia (2000-2016): pooled evidence from demographic and health survey

Background Exposure to children's stool may present a greater health risk. But, in many settings including Ethiopia children's stools often considered not harmful, and do not end up in a toilet. Even those with access to sanitation facilities often fail to use them for disposal of child feces. Importantly, Ethiopia ranked among the worst third of 38 African countries whose children feces are safely disposed of.Therefore, the study aims to determine the pooled prevalence of unsafe disposal of children's stools in Ethiopia, the predictive factors associated with it and finally it examines the trend of child stool disposal in Ethiopia.Methods The pooled data for this study obtained from the demographic and health survey (DHS) done in Ethiopia between 2000 and 2016. Descriptive statistics were computed to illustrate the given data. Binary multivariable logistic regression was employed to identify the predictors of unsafe child stool disposal.Results The pooled data contained 26,014 children's with their mother, which were included in the study. Of these, 76.1% (95%CI: 74.7-77.5) of them were unsafe child stool disposal. The trend confirms that the prevalence of unsafe child stool disposal was falling from 90.8% in 2000, to 80.4% in 2005, 65.0% in 2011, and 63.1% in 2016. In the adjusted multivariable model, being male gender [AOR: 1.15, 95%CI (1.04-1.27)], child age (children aged 13–24 months [AOR: 0.71, 95%CI (0.62-0.80)]; children aged ≥ 25 months [AOR: 0.71, 95%CI (0.61-0.81)]), mother age (mother aged 25-34 years [AOR: 0.69, 95%CI (0.61-0.79); mother aged >=35 years [AOR: 0.71, 95%CI(0.61-0.83)]), mother's working status [AOR: 0.81, 95%CI (0.72-0.91)], mother's education [AOR: 2.61, 95%CI (1.69-4.01)], residence [AOR: 2.27, 95%CI (1.79-2.89)], latrine type [AOR: 3.23, 95%CI (2.75-3.79)], and media exposure [AOR: 1.52, 95%CI (1.34-1.73)] remained strong predictors of unsafe child stool disposal.Conclusion In Ethiopia, almost three in four children's stool disposed unsafely, and maternal education and working status, children age,and type of sanitation facility were found to be predictive of unsafe child stool disposal. Thus, it is necessary to strengthen efforts focusing on child stool disposal behavioral to reduce the significant burden of unsafe child stool disposal and through careful consideration of these identified factors.
In-plane all-photonic transduction method for silicon photonic microcantilever array sensors

In-plane All-photonic Transduction Method For Silicon Photonic Microcantilever Array Sensor Jong Wook Noh Department of Electrical and Computer Engineering Doctor of Philosophy We have invented an in-plane all-photonic transduction method for photonic microcantilever arrays that is scalable to large arrays for sensing applications in both bioand nanotechnology. Our photonic transduction method utilizes a microcantilever forming a single mode rib waveguide and a differential splitter consisting of an asymmetric multimode waveguide and a Y-branch waveguide splitter. The differential splitter’s outputs are used to form a differential signal that has a monotonic response to microcantilever deflection. A differential splitter using an amorphous silicon strip-loaded multimode rib waveguide is designed and fabricated to demonstrate the feasibility of the in-plane photonic transduction method. Our initial implementation shows that the sensitivity of the device is 0.135×10 nm which is comparable to that of other readout methods currently employed for static-deflection based sensors. Through further analysis of the optical characteristics of the differential splitter, a new asymmetric double-step multimode rib waveguide has been devised for the differential splitter. The new differential splitter not only improves sensitivity and reduces size, but also eliminates several fabrication issues. Furthermore, photonic microcantilever arrays are integrated with the differential splitters and a waveguide splitter network in order to demonstrate scalability. We have achieved a measured sensitivity of 0.32×10 nm, which is 2.4 times greater than our initial result while the waveguide length is 6 times shorter. Analytical examination of the relationship between sensitivity and structure of the asymmetric double-step rib waveguide shows a way to further improve performance of the photonic microcantilever sensor. We have demonstrated experimentally that greater sensitivity is achieved when increasing the step height of the double-step rib waveguide. Moreover, the improved sensitivity of the photonic microcantilever system, 0.77×10 nm, is close to the best reported sensitivities of other transduction methods (~10 nm).
Simulation and optimisation of the controls of the stock preparation area of a paper machine.

At Mondi Paper Ltd, Merebank, South of Durban, Paper Machine 2 has recently been transferred onto a Distributed Control System (DCS). This was seen as a good opportunity to enhance the control of the pulp feed to the machine. A prime concern in operating a paper machine is to ensure consistent set-point paper properties in the Cross-Direction (CD: ie. across the paper width) and in the Machine-Direction (MD: ie. along the paper length). Sophisticated adjustments are available to ensure an even feed of the stock (consistencies around 2% m/m wood fibres in water) from the head-box across the receiving width of the paper machine. The properties of prime interest as the pulp is pumped through the head-box distributor onto the receiving belt of the machine are the basis weight (fibre mass per unit area) and moisture content (per unit area). However, the distribution system is highly dependent on the properties of the stock as it arrives at the head-box. Variations in upstream chest levels, the supplied pressure, flow-rate and fibre/water ratio, all cause MD and even CD variations. The problems of maintaining steady conditions at the head-box are well known, and are understood to arise from sub-optimal control in the preceding section involving a blend chest and machine chest, amongst other items, where several pulp streams and dilution water are combined. A number of control loops are involved, but appear to require different tuning for different paper grades. Often individual loops are taken off-line. In this study, an understanding of the controller interactions in the stock preparation section has been developed by detailed dynamic modelling, including all of the existing control loops. The model is built up in a modular fashion using a basic element, having one input (which can collect multiple streams originating elsewhere) and four outputs, linked through a vessel of variable volume. Several basic elements are linked together to form the overall system. All of the necessary properties can be defined so that the model allows the simulation of all features of the network: vessels, pipes, junctions, valves, levels and consistencies. A set of first order differential equations is solved which includes total water balance, species mass balances, derivatives of flow controller action, and derivatives of supervisory controller action. Supervisory controllers for consistency or level cascade onto flow controllers. Flow
Prototype Data Models and Data Dictionaries for Hanford Sediment Physical and Hydraulic Properties

The Remediation Decision Support (RDS) project, managed by the Pacific Northwest National Laboratory (PNNL) for the U.S. Department of Energy (DOE) and the CH2M HILL Plateau Remediation Company (CHPRC), has been compiling physical and hydraulic property data and parameters to support risk analyses and waste management decisions at Hanford. In FY09 the RDS project developed a strategic plan for a physical and hydraulic property database. This report documents prototype data models and dictionaries for these properties and associated parameters. Physical properties and hydraulic parameters and their distributions are required for any type of quantitative assessment of risk and uncertainty associated with predictions of contaminant transport and fate in the subsurface. The central plateau of the Hanford Site in southeastern Washington State contains most of the contamination at the Site and has up to {approx}100 m of unsaturated and unconsolidated or semi-consolidated sediments overlying the unconfined aquifer. These sediments contain a wide variety of contaminants ranging from organic compounds, such as carbon tetrachloride, to numerous radionuclides including technetium, plutonium, and uranium. Knowledge of the physical and hydraulic properties of the sediments and their distributions is critical for quantitative assessment of the transport of these contaminants in the subsurface, for evaluation of long-term risks and uncertainty associated with model predictions of contaminant transport and fate, and for evaluating, designing, and operating remediation alternatives. One of the goals of PNNL's RDS project is to work with the Hanford Environmental Data Manager (currently with CHPRC) to develop a protocol and schedule for incorporation of physical property and hydraulic parameter datasets currently maintained by PNNL into HEIS. This requires that the data first be reviewed to ensure quality and consistency. New data models must then be developed for HEIS that are approved by the HTAG that oversees HEIS development. After approval, these new data models then need to be implemented in HEIS by the EDM before there is an actual repository for the data. This document summarizes modifications to previously developed data models, and new data models and data dictionaries for physical and hydraulic property data and parameters to be transferred to HEIS. A prototype dataset that conforms to the specifications of these recommended data models has been identified and processed, and is ready for transfer to CHPRC for inclusion in HEIS. Additional datasets are planned for transfer from PNNL to CHPRC in FY11.
Sarcopenic is associated with hypertension in older adults: a systematic review and meta-analysis

BackgroundBoth sarcopenia and handgrip strength have been observed association with hypertension. However, the results in different studies were inconsistent. In the current study, we conducted a systematic review and meta-analysis to reveal the association between sarcopenia, handgrip strength, and hypertension in older adults.MethodsPubMed, MEDLINE, Cochrane Library, and EMBASE databases were searched from inception to 15 November, 2019for original research studies. The studies that addressed the association between sarcopenia, handgrip strength, and hypertension were included and summarized.Results19 studies met the inclusion criteria and a total of 21301 were included in the meta-analysis. Eight eligible studiesreported the odd ratios (ORs) of hypertension and the ORs ranged from 0.41 to 4.38. When pooled the ORs together, the summarized ORs was 1.29 [95% confidence interval (CI) =1.00-1.67]. The summarized ORs for the Asian group 1.50 (95% CI=1.35-1.67) was significantly higher than that of Caucasian group 1.08 (95% CI=0.39-2.97). Eleven studies provided the data on association between handgrip strength and hypertension. The overall ORs and 95% CI was 0.99 (95% CI=0.80-1.23), showing no association.ConclusionSarcopenia was associated with hypertension but no correlation was found between handgrip strength and hypertension in older adults.
The EAP course design Quagmire – juggling the stakeholders’ perceived needs

This chapter explores perspectives of administrators, ESP teachers and MBA students in a Pakistani university on the English language needs of MBA students. It further tries to explore the strife caused by the administrative differences in opinion and outlook on the university’s system that restrain it from bringing much needed change in the curriculum. In doing so the chapter also looks for a way forward, that is, a way to meet the English language needs of MBA students despite the disparity in the three respective standpoints. It also offers implications of this study to other global EAP contexts.
