High performance energy efficient file storage system

Recently energy has become a critical resource in modern computing systems. In mobile computers, disk sub-systems consume a major portion of available energy, which reduces battery life and thus limits the utility the whole system. In data intensive environments, the energy consumption of the I/O storage subsystem may easily surpass the energy consumed by the rest of the computing system. The direct and indirect cost of energy consumption is a limiting factor in deploying and operating data-intensive computing systems. This dissertation aims to provide energy saving solutions for both client side and server side environments, with the latter as the focus. For the client side systems, this work proposes a new energy-efficient file system called EEFS, to reduce energy consumption and improve performance by separately managing small-sized files with good group access locality. Because of the workload intensity, energy-efficient I/O solutions for client systems usually cannot be applied to data servers. Multi-speed disks were introduced by previous research work to make it possible to lower the disk energy consumption in I/O intensive environments. For multi-speed disk based server systems, this dissertation provides an energy-efficient RAID system named EERAID. Furthermore, this work addresses the open question of saving energy for conventional disk based storage servers by providing the policies EPRAID and eRAID, for RAID5 and RAID1 systems respectively.
Energy Use in Swedish Forestry and its Environmental Impact

The commitments to sustainable development made by the member countries of the UN, together with the Kyoto Protocol, has raised the profile of issues related to the ecological evaluation of products, production processes and services. In each of the studies underlying this thesis a LCA (Life Cycle Assessment) perspective was adopted. Firstly, site-specific data were collected from three forest management regions in northern, central and southern Sweden in the late 1990s. Secondly, silvicultural and technological forestry developments between the early 1970s and late 1990s were evaluated by comparing the energy use in the forestry system at each of these times. Secondary transport of timber was found to be the most energy-demanding part of the forestry system usually, accounting for about 50 percent of the energy demands, and logging was generally the second most energy-demanding process (33-40 percent), except in systems involving mechanized logging operations in 1972, when logging required the most energy (60 percent). These findings show that increased mechanization since 1972 has not resulted in a rise in total energy use; in fact, it has led to more energy-efficient logging machines, from motor-manual and early mechanised systems, to current machines that are on the verge of automisation. In contrast, energy use in silviculture has increased, possibly due to the use of more supposedly advanced technology and more intensive silvicultural treatments. The same is also true for secondary haulage because of the greater use of road vehicles and longer haulage distances. An analyse of future possible secondary timber transport scenarios involving lorry or lorry-and-train combinations using a variety of potential fuels/energy carriers showed that in biobased-fuel cycles the greenhouse gas emissions are about 96 percent lower than in corresponding fossil fuel cycles. In addition, they involve little fossil energy. Given the expected future scarcity of fossil fuels, and potential consequences of global warming, it could be advantageous for the forest sector to both produce and use a renewable fuel, since it could increase the overall value of forest products and have a low environmental impact.
Molecular characterization and serodiagnostic potential of two serpin proteins in Psoroptes cuniculi

Background: Psoroptes cuniculi is a global common ectoparasite of wild and domestic rabbits and causes an economically devastating loss and serious welfare issues of commercial rabbit husbandry. Serine proteinase inhibitor (serpin) is present in almost all organisms that are involved in host-pathogen interactions, inflammatory responses, and reproductive development, etc. However, the research on P. cuniculi serpins is still limited.Methods: In this study, two serpin genes of P. cuniculi (Pso c 27 and PsoSP2 cDNAs) were cloned, and the molecular characterization was analyzed. The transcriptional profiles and tissue localization of these two serpins in P. cuniculi were investigated by quantitative real-time PCR and immunohistochemistry, respectively. The potential function of recombinant Pso c 27 and PsoSP2 (rPso c 27and rPsoSP2) in the serodiagnosis of P. cuniculi infestation in rabbits were evaluated by indirect enzyme-linked immunosorbent assay (iELISA). Results: Both of the 523 residue Pso c 27 and the 240 residue PsoSP2 proteins contained typical serpin domains and signatures. Both Pso c 27and PsoSP2 cDNAs expressed throughout the life-cycle, more specifically, significantly higher expression in female mites than the larva, nymph, and male mites (Pso c 27, F(3, 8) = 1935.953, P < 0.0001; PsoSP2, F(3, 8) = 660.669, P < 0.0001). The native Pso c 27 and PsoSP2 localized in ovary and mouthpart of adult female mites, respectively. Compared to rPsoSP2, the rPso c 27 displayed better diagnostic efficiency with higher values of sensitivity, specificity and the area under the receiver operating characteristic curve (AUC) (rPso c 27 vs rPsoSP2: 96.0 vs 90.0%; 90.91 vs 78.18%; 0.988 vs 0.964, respectively). Moreover, the rPso c 27 showed seropositive in 80% rabbits as early as the 2 weeks post-infestation (p.i.), prior to visible clinical signs and microscopy-positive of skin scrapings. Conclusions: These results suggested that these two serpins may play essential roles in reproductive development, serum-feeding, and pathogenicity of P. cuniculi. Compared to PsoSP2, Pso c 27 appeared as a potential antigen for serodiagnosis of P. cuniculi infestation in rabbits, especially at the early stage of infestation.
Investigation of Aperture Coupled Microstrip Antenna to Obtain a High Efficient Active Integrated Antenna by Using Class F and Inverse Class F Power Amplifiers

In wireless communications and radar systems, there are requirements for high efficiency, small size, low cost, and wide bandwidth of transmitter front –end usage for commercial and also military applications. Active integrated antenna (AIA) could satisfy almost all the requirements. The overall objective of the proposed research is to model, optimise, and design a compact and high efficient AIA using an aperture coupled microstrip antenna (ACMA) by integrating with a power amplifier (PA). Research on ACMA has been focused on the transmissions line (TL) model (TLM) and full wave electromagnetic (EM) model analysis. The full wave investigation is rigorous and elegant but because the dimension of the physical model and the value of the circuit elements are interdependent, the design of the antenna is still difficult. TLM analysis has lower accuracy but easier to analysis and optimise than full wave EM model analysis. To increase the accuracy, the challenge is the coupling ratios between feed/slot, and slot/patch where no unique solution at the moment exists. In this thesis, a novel and simplified method has been produced to investigate these ratios using Scattering (S) parameters. A dual frequency ACMA has been designed to verify these results. Research on the class F and inverse class F PAs is carried out by a novel and simplified load/pull method. A new design method of harmonic load matching network has been presented using lump elements and TLs. Both linear and nonlinear modelling has been investigated. High power added efficiency (PAE) and high gain which are up to 60% and 12dB have been obtained. Finally AIAs have been produced based on previous investigation on class F, inverse class F PAs and a broadband circular polarized ACMA design with 350 MHz bandwidth and 8.5 dB gain at 2 GHz.
Microcystin algal toxins in Source and Finished Drinking Water

The number and intensity of reported blue‐green algae (cyanobacteria) blooms in reservoirs, lakes, ponds, and rivers have increased worldwide. Some species of cyanobacteria are capable of producing microcystins, hepatotoxins that can cause liver damage, shock, and in some cases, death to mammals ingesting contaminated water. In 1998 and 1999, studies were conducted to elucidate the occurrence of microcystin toxins in raw and finished water from five drinking water treatment facilities in Wisconsin. Samples were collected and analyzed for microcystins using an enzyme‐linked immunosorbent assay. Microcystin toxins were repeatedly found in the raw water. Conventional water treatment practices used by the facilities effectively removed microcystins by 1‐3 logs. The data collected suggest that microcystin toxin removal occurs incrementally at several points in the drinking water treatment train.

Performance of Various Deep-Learning Networks in the Seed Classification Problem

We report the results of an in-depth study of 15 variants of five different Convolutional Neural Network (CNN) architectures for the classification of seeds of seven different grass species that possess symmetry properties. The performance metrics of the nets are investigated in relation to the computational load and the number of parameters. The results indicate that the relation between the accuracy performance and operation count or number of parameters is linear in the same family of nets but that there is no relation between the two when comparing different CNN architectures. Using default pre-trained weights of the CNNs was found to increase the classification accuracy by ≈3% compared with training from scratch. The best performing CNN was found to be DenseNet201 with a 99.42% test accuracy for the highest resolution image set.
ANALYZING THE EFFECT OF PASSENGER-REQUESTED UNSCHEDULED STOPS ON DEMAND

This paper discusses the effect of unscheduled stops requestedby passengers on bus transit demand and presents theresults of its study. In the research a set of regression modelsthat estimate the route-level demand were developed using datacollected with Automatic Passenger Counters and AutomaticVehicle Location systems installed on buses, and demographic,socio-economic and land use information from other sources.The results obtained indicate that the number of rider-requestedunscheduled stops have no significant effect on demand,suggesting that the company policy which tolerates unscheduledstops is inadequate for attracting new riders.
Lightning protection of overhead power distribution lines

There are two major protective methods against lightning outages on overhead distribution lines. One is by use of surge arresters and the other is by an overhead ground wire. Surge arresters have rather constant effect regardless of the type of lightning outage causes. On the other hand, the effect of an overhead ground wire is quite different against the two major causes: direct lightning hit and induced overvoltages. This paper shows how to design lightning protection for overhead power distribution lines taking these characteristics into account. Copyright © 2007 Institute of Electrical Engineers of Japan.

Metabolic and Inflammatory Benefits of Reducing Preoperative Fasting Time in Pediatric Surgery.

OBJECTIVE To investigate the metabolic/inflammatory impact of reducing the preoperative fasting time in preschool children. METHODS Forty children were randomly assigned to a fasting group (absolute fasting after 00:00) and a carbohydrate (CHO) group (allowed to ingest, two hours before surgery, a carbohydrate-rich beverage). Blood samples were collected right before and after surgery to quantify the levels of albumin, interleukin-6, glucose, insulin, C-reactive protein and to calculate insulin resistance by the HOMA-IR index. RESULTS Preoperative fasting time in the CHO group were shorter than in the fasting group (2.49h vs. 11.24h, p <0.001). Pre- and post-surgical CRP levels were significantly lower in the CHO group (p = 0.05 and p = 0.02, respectively). The preoperative CRP/albumin ratios in the CHO group were lower than in the fasting group (p = 0.03). Four patients (21%) in the fasting group but none in the CHO group were hyperglycemic before surgery (p = 0.04). The two groups had similar levels of albumin, interleukin-6, insulin and HOMA index. There were no adverse events. CONCLUSION Reducing the preoperative fasting time with carbohydrate-rich beverages improves the perioperative metabolic and inflammatory responses of preschool children undergoing inguinal hernia surgery.
Emirati Women: Generations of Change

The discovery of oil in the late 1960s catapulted Abu Dhabi out of isolating poverty. A boom in construction introduced new sightlines to the city's landscape and transformed its infrastructure and economy. The impressive growth of just a few decades created new opportunities for work and play and developed a social welfare system that offered free education and medical treatment, generous pensions, family subsidies, and government incentives. Citizens were suddenly encouraged to participate in all aspects of their remaking, and wealth from a seemingly limitless oil economy enabled many households to acquire a sheen of sophistication. The pattern of Abu Dhabi's phenomenal growth can be traced throughout the United Arab Emirates, and oil wealth can be felt among their societies as well. Yet conspicuous consumption hasn't cast the Emirates in a very favorable light. Both at home and abroad, many have accused Emirati citizens of violating the limits of taste and tolerance. Emirati Women offers rare perspective on those who have been affected most by the Emirates' rise in power. Jane Bristol-Rhys merges eight years of conversations and interviews with three generations of women and her own personal observations on Abu Dhabi society, boldly confronting the unflattering stereotypes that quietly flourish among expatriate communities. She also shares her unique findings on such topics as marriage, independence, freedom, and the future.
Driver vision screening: pilot study

This pilot study was carried out to investigate the association with age and crash involvement of: (1) the British number plate test; (2) some alternative tests of basic visual function (Ergovision screener: photopic visual acuity, mesopic visual acuity, dynamic visual acuity, low contrast visual acuity, visual fields, dazzle recovery, stereopsis, heterophoria and colour vision); and (3) a test of higher order perceptual function (Useful Field of View Visual Attention Analyser). Drivers (67 with crashes, 217 without) were screened at 29 venues in England and North Wales. Age, gender, annual mileage and self reported "at fault" crash involvement (over the last 5 years) were recorded. Associations between vision screening scores versus age and crash involvement were tested for statistical significance using Chi-square with Yates' correction. The main conclusions arising from this study were that: (1) The British number plate test showed no significant association with age or crash involvement; (2) Many of the basic visual functions deteriorated significantly with advancing age. However, only a derivative of the test for low contrast visual acuity (referred to as contrast susceptibility) exhibited significant associations with crash involvement in younger and older drivers; and (3) Visual attention also significantly reduced with advancing age but no significant association with crash involvement was demonstrated - although the association recorded for older drivers exceeded that found for younger drivers.

Population-level effects of diet, lifestyle, and health environment on obesity and non-communicable diseases in India

Background: Obesity is rising in developing countries like India and is associated with an increase in cardiometabolic problems. Rising incomes, rapid urbanization, and mechanization have induced lifestyle changes like consumption of more obesogenic foods and sedentary habits at work and leisure, contributing to a transition from under- to over-nutrition. This study maps the prevalence of adult (15-49 years) overweight and obesity across regions and socioeconomic groups in India, and estimates its association with lifestyle, health environment, dietary patterns, diabetes, and hypertension.Methods: We employ a combination of 3 latest nationally representative datasets with over 700,000 adults. We use a linear probability regression model to identify the correlates of overweight/obesity and their relative magnitudes. We use intra-household regression to identify differences between men and women and coarsened exact matching to causally estimate the impact of obesity on diabetes and hypertension.Results: Overweight/obesity rates have increased across all states, in rural and urban areas, and for all wealth levels. Women are more likely to be overweight/obese than men, even in the same household. Improved health environment (toilets, piped water, clean cooking fuel), urban jobs, television watching, and processed snacks increase the risk of overweight/obesity. Adults who are overweight/obese have a 5.6% higher risk of diabetes and a 9.7% higher risk of hypertension.Conclusions: Our results underscore the need for policy intervention to reduce the burden of obesity and NCD’s in India.
Air flow in a high aspect ratio heat sink

The increasing heat output of modern electronics requires concomitant advances in heat sinking technology: reductions in thermal resistance and required pumping power are necessary. This research covers the development of a novel type of air-cooled heat sink, in particular the air flow through such a heat sink. The research is carried out through theory, computation, and experiment. A nondimensionalization is carried out to determine scaling laws for such heat sinks. Correlations are provided for the prediction of performance of similar heat sinks. Using these scaling laws a heat sink with an air flow volume of 35 cm is described with a convection thermal resistance of 0.43 KW for a pumping power of 0.72 W. Thesis Supervisor: John G.

Turbocharging Concepts for Downsized DI Gasoline Engines

Reducing engine swept volume (so-called 'downsizing') offers the potential to meet future tighter CAFE standards and reduced CO 2 vehicle emissions in Europe. In downsizing the gasoline engine, a key challenge is controlling octane requirement without sacrificing fuel economy. The authors have investigated five alternative approaches on a turbocharged Dl gasoline engine: ○ Conventional stoichiometric operation, with reduced compression ratio (CR) ○ Lean Boost Dl (LBDI) with lean operation at full-load to control octane requirement while maintaining a high CR ○ EGR Boost with cooled EGR dilution rather than excess air to control octane requirement ○ Miller cycle concept, where valve-timing strategies are employed to reduce the effective compression ratio at high load ○ Dual injection strategies to control octane requirement Each approach has been investigated using engine performance and vehicle simulation codes. Experimental investigations have been carried out using a 1.125L 13 multi-cylinder engine. The most promising concept, LBDI, has been further developed using the multi-cylinder engine installed in a Ford Focus C-class vehicle.
