Evaluation of the Solute Transport Characteristics of Surcharged Manholes using a RANS Solution

Urban drainage networks contain a large number of structures; the most common of which is a manhole. Previous studies investigating solute transport through manholes identified a threshold level of surcharge at which the hydraulic conditions in the manholes sharply altered. At high levels of surcharge, a dead zone formed above the main jet, potentially retaining solute for later discharge. This phenomenon could have significant impacts on the results obtained from 1D urban drainage network models which only consider pure advection. Previous research (including other CFD based studies) concentrated on steady flow conditions through these structures which are not thought to be representative of the dynamic flow conditions experienced in practice. During large storm events, the capacity of combined sewer networks may be exceeded. This leads to the discharge of untreated sewage to receiving watercourses. Discharges such as these are governed by legislation and, therefore, an understanding of pollutant transfer through urban drainage networks is required. Using existing laboratory and Computational Fluid Dynamics (CFD) data, this study produced a primary and secondary validated methodology for meshing and modelling manholes using CFD. This was then extended to free-surface multiphase modelling allowing for more realistic unsteady conditions to be considered. This included an in-depth comparison of suitable turbulence models and solute-modelling options. It was found that, whilst it was possible to model multiphase free-surface flow within such a structure, it was unnecessarily computationally expensive as temporal changes in the flow field are rapid when compared with a practical time-step for use with 1D models. The validated modelling methodology was then used to recreate the original study that identified the hydraulic threshold. This included a selection of manholes with a range of inlet to manhole diameter ratios. However, this was extended further to include manholes with a ratio less than five (commonly found in UK sewer systems). It was shown that the hydraulic threshold broke down below this limit, removing the need for this to be modelled in 1D systems.
Physical layer loading algorithms for indoor wireless multicarrier systems

The demand for wireless networks has been growing rapidly over the recent past due to improved reliability, higher supported data rates, seamless connectivity between users and the access point, and low deployment costs relative to wireline infrastructure. This increase in demand started with the popular IEEE 802.11b wireless local area network standard. Many recent wireless network standards are now employing multicarrier modulation in their design. Multicarrier modulation reduces the system's susceptibility to the frequency-selective fading channel, due to multipath propagation, by transforming it into a collection of approximately flat subchannels. As a result, this makes it easier to compensate for the distortion introduced by the channel. However, standardized wireless modems, such as the ETSI HiperLAN/2 and the IEEE 802.11a standards, employ the same operating parameters across all subcarriers, and thus do not exploit all the advantages offered by the multicarrier framework. This dissertation investigates techniques to further enhance system throughput performance by tailoring several operating parameters on a per-subcarrier basis. These parameters are subcarrier modulation schemes, power levels, and equalizer lengths. The idea of tailoring modulation schemes and power levels, known as bit allocation and power allocation, has been studied for many years and for many applications. This work proposes two novel discrete bit allocation algorithms that strive to reach the optimal solution in a low computational complexity fashion, while constrained to a specified error performance. A novel power allocation algorithm is proposed that satisfies regulatory requirements by obeying a frequency interval power constraint. Investigation of the third parameter, subcarrier equalizer lengths, has not been conducted before in the literature. Two algorithms are proposed that vary the lengths of the subcarrier equalizers such that the overall distortion is reduced to some specified amount, while the number of equalizer taps used by the system are kept small. Finally, the use of bit allocation is extended to the case when multiple antennas are employed by the wireless modems. Four algorithms are proposed that perform generalized antenna selection diversity at both the transmitter and receiver, in tandem with discrete bit allocation. Results show that employing two transmit and two receive antennas with discrete bit allocation can achieve an average increase in throughput of up to 33% when compared to a system without bit allocation.
Considerations for Design Criteria for Lunar Structures

The development of design criteria for lunar structures must begin soon in order to establish adequate criteria. Some of the items that need consideration in such criteria are discussed. The categorization of the structures will provide designers with information on the purpose and level of complexity of the structure. Various construction materials and structure types that will be critical for the design of lunar structures, are considered. The environment of the moon and its possible effects on structures are presented and lead to the development of a few load cases that need to be considered in design. A probabilistic format for the criteria and design lifetimes are also discussed.
Overview of SLOPE I and II campaigns: aerosol properties retrieved with lidar and sun-sky photometer measurements

Abstract. The Sierra Nevada Lidar aerOsol Profiling Experiment I and II (SLOPE I and II) campaigns were intended to determine the vertical structure of the aerosol by remote sensing instruments and test the various retrieval schemes for obtaining aerosol microphysical and optical properties with in-situ measurements. These campaigns deployed a set of in-situ and remote sensing instruments at the stations include in AGORA observatory (Andalusian Global ObseRvatory of the Atmosphere) in the Granada area (Spain) along summer in 2016 and 2017. In this work, using the in-situ measurements performed at a high-altitude station, Sierra Nevada station, and airborne flights, we evaluate the retrievals of aerosol properties by GRASP code (Generalized Retrieval of Atmosphere and Surface Properties) combining lidar and sun-sky photometer measurements. Besides, we show an overview of aerosol properties retrieved by GRASP during SLOPE I and II campaigns. We evaluate the GRASP retrievals of total aerosol volume concentration (discerning between fine and coarse modes), extinction and scattering coefficients, and for the first time we present an evaluation of absorption coefficient. The statistical analysis of the aerosol optical and microphysical properties, both column-integrated and vertically-resolved, from May to July 2016 and 2017 shows a large variability in aerosol load and types. The results show a strong predominance of desert dust particles due to the North African intrusions. The vertically-resolved analysis denotes a decay of the atmospheric aerosols with altitude up to 5 km a.s. l. Finally, two events of desert dust and biomass burning were used to show the high potential of GRASP to retrieve and study the aerosol properties profiles such as absorption coefficient and single scattering albedo for different aerosol types. The aerosol properties retrieved by GRASP show good agreement with simultaneous in situ measurements performed at Sierra Nevada Station (SNS) in Granada. In general, GRASP overestimates the in situ data at SNS with a mean difference lower than 6 µm3/cm3 for volume concentration, 11 Mm−1 and 2 Mm−1 for scattering and absorption coefficient. On the other hand, the comparison of GRASP with airborne measurements also shows an overestimation with mean absolute differences of 14 ± 10 Mm−1 and 1.2 ± 1.2 Mm−1 for scattering and absorption coefficients, showing a better agreement for absorption (scattering) coefficient with higher (lower) aerosol optical depth. The potentiality of GRASP showed in this study will contribute to enhancing the representativeness of the aerosol vertical distribution and provide information for satellite and global model evaluation.

Sustainable and Healthy Travel Choices and the Built Environment: Analyses of Green and Active Access to Rail Transit Stations along Individual Corridors

Until recently, data and technology have limited the ability of travel behavior research to uniquely capture details of the built environment that may influence a person's choice to walk or bicycle. Most previous studies have relied on aggregated zonal averages homogeneously attributed to unique individuals and have likely missed key subtleties of the built environment important to people traveling outside the protective enclosure of an automobile. Furthermore, most studies focus on the characteristics of the origin, not the critical components of the destination (such as parking, availability, and price). To understand better the choice of green and active modes, which is central to an understanding of how to achieve important environmental and health benefits, this paper presents methods to align detailed measures of the built environment (in sum, more finely disaggregated data of the built environment) more closely with the individual for disaggregated analyses of travel behavior. Through the use of a new, linear spatial unit of analysis—the individual access corridor—characteristics of the built environment are captured all the way from the origin to the destination for a group of individuals large enough to be statistically meaningful for policy and urban design guidance through the use of predictive, multinomial logit mode choice models. This study provides planning and design guidance on how to increase the likelihood that one will choose walking or bicycling over motorized modes and examines such elements as zoning, subdivision ordinances, and streetscape design as well as station policies for bicycle and auto parking.

A Comprehensive Light Vehicle Antilock Brake System Test Track Performance Evaluation

To determine if situations and/or conditions exist in which ABS-equipped vehicles do not perform as well as those without ABS, the braking performance of nine passenger vehicles was observed over a comprehensive array of driving conditions. For most maneuvers, on most surfaces, ABS-assisted stops yielded distances shorter than those made with the ABS disabled. The one exception was on loose gravel where stopping distances increased by an average of 27.2 percent overall. Additionally, the vehicular stability observed during testing was almost always superior with ABS. For the cases in which instability was observed, ABS was not deemed responsible for its occurrence.

Cross coupling between power and signal traces on printed circuit boards

Switching power supplies and other power switching circuits produce high frequency components in currents on power traces and power grounds in printed circuit boards (PCBs). These time-varying currents can couple energy (noise) to low level signal traces such as those normally encountered with the new low voltage high speed logic families and microprocessors. This can cause the system to malfunction or result in EMI emissions that exceed the levels allowed by regulatory agencies. The effect of proximity and position of power switching circuits with respect to the signal traces is examined.

Coexistence of Mother Overweight and Stunting Children Within the Same Household in West Africa : Associated Factors

BackgroundThe double burden of malnutrition is the new reality in many low- and middle-income countries. Updating and meeting the challenge of double burdens on vulnerable people is essential to ensure healthy growth. This study is to explore the individual or household factors that may be associated with coexistence of mother overweight and stunting children within the same household (MOSC) in the West African countries. Besides, we sought to examine its prevalence using data from national surveys.Methods: We used nationally representative data from the Demographic and Health Survey of 11 West African countries. Data years range from 2012 to 2014. We used logistic regression to explore the association between the occurrence of coexistence of mother overweight and stunting children within the same household and individual or household factors. Logistic regression was performed on the pooled data to allow comparison between countries ranked by gross national income. Results: The Prevalence of MOSC was higher in Benin 11.52% (95%CI, 10.61-12.43), the lowest proportion was in Togo and Guinea [4.83% (95%CI, 3.88-5.77), 4.48% (95%CI, 3.57-5.40), respectively]. Women who did not receive antenatal cares were associated with higher odds of MOSC occurrence compared to those who received more than 4 antenatal cares in all countries except Gambia, this association was significant in 7 countries among which the MOSC in Ghana was four times more likely to occur in women who did not receive antenatal care compared to more than 4 antenatal cares [odds ratio (95%CI): 4.936 (2.701-9.019)]. Children over 24 months of age were significantly associated with higher odds of MOSC occurrence compared to under 24 months in all countries except Sierra Leone [odds ratio (95%CI): 1.215 (0.867-1.703)]. Conclusions: In this study, none of the individual and household factors were strongly associated in the same way with MOSC occurrence in West African countries, they varied considerably between national databases and independent of national income per capita. However, Children's age and antenatal cares were the two covariates strongly associated with MOSC occurrence in most countries.
Variability in Residential Air Leakage

Air leakage is the single most important quantity in the determination of air infiltration in residential structures. Air leakage is most commonly measured using the fan pressurization technique (See ASTM standard E779); the data gathered with this method is often used to determine a leakage constant and a flow exponent. In this report, data gathered from the literature will be compiled into a list of leakage constants and flow exponents, and the variability of these values over climate and housing types will be examined. 6 refs., 6 figs., 2 tabs.
AMELIORATIVE EFFECT OF FRESH GARLIC AND VITAMIN E AGAINST LINEZOLID INDUCED HEPATO-RENAL OXIDATIVE DAMAGE IN RATS

The present study was conducted to compare between the protective effect of either garlic or vitamin E (Vit E) against hepatic and renal damage induced by 100mg/ kg linezolid (LNZ) administration. Thirty male albino rats were allocated into equal six groups; first three control groups; (control, tween 80 and olive oil); Group4; received 100mg LNZ / kg for 14 consecutive days. The last two groups were administered either garlic (500 mg/kg) or Vit E (100 mg/kg) prior to LNZ administration daily for 14 consecutive days. Blood samples were obtained from all rats for biochemical investigations and oxidative stress biomarkers. Specimens from liver and kidneys were excised for histopathological investigation. Linezolid induced a significant elevation in serum Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Alkaline phosphatase (ALP) and urea. Alterations in antioxidant / oxidant status were noticed during LNZ administration . Administration of garlic or Vit E modulated the previous parameters and restored histological structures. In conclusion, both garlic and Vit E were able to ameliorate hepato-renal alterations induced by LNZ via their antioxidant effects.
Efficiency enhanced CMOS digitally controlled dynamic bias switching power amplifier for LTE

This article presents an efficiency enhanced CMOS power amplifier using a digitally controlled dynamic bias switching method. It is composed of a dynamic bias switching circuit and a power amplifier circuit. The control signal for bias switching operation is generated by the digital signal processing unit according to the amplitude of the envelope signal. Then, the dynamic bias switching circuit offers two different supply voltages to the drain of the power amplifier. The low supply voltage is generated by a DC–DC converter within the dynamic bias switching circuit, while the high voltage can be directly supplied by the battery. The threshold voltage for the envelope signal and the low supply voltage level were analytically optimized for maximum efficiency enhancement using the envelope statistics of the LTE signal. The gain difference between low and high bias voltage conditions was compensated for better linearity of the power amplifier. The proposed dynamic bias and power amplifier IC's were designed and fabricated using 0.18 μm CMOS process. The fabricated CMOS power amplifier IC using the dynamic bias switching method was evaluated using a 64 QAM LTE up‐link signal which has a center frequency of 1.75 GHz, a signal bandwidth of 5 MHz, and a peak‐to‐average power ratio of 7.76 dB. It exhibited a power‐added efficiency of 39.3% and an error vector magnitude of 4.6% at an average output power of 22 dBm, while the stand‐alone CMOS power amplifier has an efficiency of 34.5%. © 2015 Wiley Periodicals, Inc.
