unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Abstract. There is notably paucity of studies on least-squares estimator of diffusion process for discrete observations. This paper discusses sufficient conditions of the least-squares estimator of diffusion process for discrete observations in order to gain an estimator that is strongly consistent of [1]. We assume that the process Y is arranged by a function such as sinusoidal signal a(θ ,Yt) = sin(2πtθ),θ ∈ [ 0, 2 ] and function b(σ ,Yt). For a given a sample (Y0,Yh, . . . ,Ynh), h→ 0, we demonstrate an asymptotic theory of least-squares estimator θ̂n. The results of the study show that the least-squares estimator is strongly consistent and asymptotic normal, assuming that nh→∞ and n3h4→∞; θ that represents the frequency of sinusoidal signal of the unity of time which has a rate of convergence, namely √ n3h4.
Lived experience of women who underwent early removal of long-acting Contraceptive Methods: A phenomenological study

Background: Long-acting contraceptive methods can play a pivotal role in reducing maternal mortality. In Etiopia, the total fertility rate per woman is 4.6. However, this rapid population growth is not in line with the weak economic growth of the country. Therefore, this study was performed to explore the lived experiences of women who underwent early removal of long-acting contraceptive methods in Bedesa town, Southern Ethiopia.Methods: A phenomenological study design was employed to include a total of 10 in-depth interviews of sampled women. Participants were recruited through the criterion sampling method. Open code version 4.03 was used to code and facilitate analysis. Transcripts were read and re-read separately to identify emerging themes. A thematic analysis technique was used.Results: This study revealed that the side effects of long-acting family planning methods were the main reason for early removal. Furthermore, heavy and irregular menses were mentioned as the most frequently occurring side effects. Delayed fertility after removal of long-acting contraceptives was one of the most frequently stated fears by clients. It was also stated that counseling provided by health professionals was not adequate.Conclusion: The majority of study participants taught that the side effects of long-acting family planning methods outweigh the benefits. In addition, the counseling services provided by health care providers were not adequate. Therefore, proper counseling services should be given to mothers who are taking long-acting family planning methods.
Covariance Modeling and Space-Time Coding for MIMO systems

Covariance Modeling and Space-Time Coding for MIMO Systems Farnaz Karimdady Sharifabad Department of Electrical and Computer Engineering Doctor of Philosophy The full spatial covariance matrix of the multiple input multiple-output (MIMO) channel is an important quantity in channel modeling, communication system signal processing, and performance analysis, and therefore this matrix forms the heart of the research outlined in this dissertation. The work begins with an investigation of a generalized framework for computing the full MIMO spatial covariance based on the power angular spectrum (PAS) of the multipath field and the transmit and receive antenna element radiation patterns. For the case of uniform linear arrays and when the PAS clusters satisfy uniform, truncated Gaussian, or truncated Laplacian distributions, a series expansion is used to allow analytic evaluation of the required integrals in the formulation. The study also demonstrates the validity of some simplifying assumptions used to reduce the complexity of the covariance computation by applying the technique to ray tracing data as well as considers an analysis of the convergence properties of the series when computed using a finite number of terms. The insights and tools obtained from this covariance analysis are then used to develop a general approach for constructing MIMO transmit and receive beamforming vectors based on the full spatial covariance. While transmit and receive beamforming for the MIMO channel is a well-studied topic, when the transmit precoding is based on channel covariance information, developing near-optimal transmit and receive beamformers when the receiver is constrained to use linear processing remains an unsolved problem. This iterative beamforming algorithm presented here can accommodate different types of available channel information and receiver capabilities as well as either a sum power constraint or a per-antenna power constraint. While the latter is more realistic, construction of the optimal transmit precoder is less understood for this constraint. Simulation results based on measured channels demonstrate that the approach generates beamformer solutions whose performance rivals that achieved for an optimal nonlinear receiver architecture.

Improved NASA-ANOPP Noise Prediction Computer Code for Advanced Subsonic Propulsion Systems. Volume 2; Fan Suppression Model Development

The Aircraft Noise Predication Program (ANOPP) is an industry-wide tool used to predict turbofan engine flyover noise in system noise optimization studies. Its goal is to provide the best currently available methods for source noise prediction. As part of a program to improve the Heidmann fan noise model, models for fan inlet and fan exhaust noise suppression estimation that are based on simple engine and acoustic geometry inputs have been developed. The models can be used to predict sound power level suppression and sound pressure level suppression at a position specified relative to the engine inlet.
INVESTIGATION OF EXPOSURE BASED PEDESTRIAN ACCIDENT AREAS: CROSSWALKS, SIDEWALKS, LOCAL STREETS AND MAJOR ARTERIALS. FINAL REPORT

Previous FHWA research on pedestrian exposure identified four problem areas as promising candidates for accident reduction: intersections without marked pedestrian crosswalks, major arterial streets, local streets, and locations lacking sidewalks or pedestrian pathways. This report describes the results of a project undertaken to examine those four problem areas. The objectives of the project were to: evaluate past research on pedestrian crosswalk markings and develop guidance for when and what type of crosswalk markings should be provided; investigate traffic engineering improvements for major arterial streets to increase pedestrian safety; investigate traffic engineering improvements for local streets to increase pedestrian safety; and examine existing guidance/warrants for the provision of pedestrian pathways and sidewalks and prepare revised guidance/warrants.
Local Corpus and Praxis in Soil Management of the Manobo Tribe in Cotabato, Philippines

A study was conducted to document the local knowledge and practices in soil management of the Manobo tribe in Cotabato Province, Philippines. This is to determine the validity of the local corpus with the western knowledge. A total of 145 key informants were selected randomly from various Manobo groups using semi-structured survey questionnaires and field documentation. A prior informed consent (PIC) was sought by the researcher and followed by a consultation dialogue with the tribal leaders, elders and other key person of the study. Manobo tribes were located in the undulating areas of Arakan, Cotabato dominated by the sub- tribes Tinananen and Kulamanen. The Arumanen were in the distant area of Carmen and Libungan while the Obo Manobo and Kidapawanen sub-tribes were situated in Magpet and Makilala, Cotabato. About 32.41percent were tribal chieftains and farming was the prime source of living. Tribal women and children were involved in major farming activities. The farming information was obtained mostly from the tribal elders (88.97%), chieftains (71.72%), and co-tribesmen (54.48%). Most of the farms were marginalized and primarily planted with upland rice, corn and root crops. Farmers practiced rotational system of gathering food, kaingin and fallow period, “tudak” or dibble method of planting, “kompak” system (communal planting), and the use of perception and actual field observation in managing the soils through the biophysical indicators. Most of the informants (88.97%) used local corpus in farming and the 90.34 percent respondents wanted to continue the indigenous knowledge important to preserve the natural resources like water (96.95%), soil (89.31%), and forest trees (85.50%). Fallow period was the known local corpus and praxis of the 78.76 percent informants including the planting of leguminous crops. The identified indigenous corpus and praxis of the Manobo were found scientifically in agreement with modern knowledge hence, considered as relevant, valid and factual.
Integrated mRNA and miRNA transcriptome analysis reveals regulatory network of yam tuber expansion

Yam tuber is a storage organ, derived from modified stem. Tuber expansion is a complex process, it depends on the expression of genes that can be influenced by environmental and endogenous factors. However, little is known about the mechanism that regulates tuber expansion. In order to identify genes and miRNAs involved in tuber enlargement, we examined the transcriptome and small RNA in yam tuber during its initiation and expansion stages. A total of 14238 differentially expressed transcripts in yam tuber at its expansion stage were identified by using transcriptome technology. Among them, 5723 genes were up-regulated and 8515 genes were down-regulated, respectively. Functional analysis revealed the coordination of tuber plant involved in processes of cell events, metabolism, biosynthesis, and signal transduction pathways at transcriptional level, suggesting that these DEGs are somehow involved in response of tuber expansion. In addition, 536 transcription factor genes showed differential expression during the expansion stage at transcriptional level. REVEILLE 6-like was identified to be up-regulated in the circadian rhythm pathway. REVEILLE 6-like LHY protein, zinc finger CCCH domain-containing protein 14, and DELLA genes were up-regulated in expansion stage. Moreover, these genes were involved in circadian rhythm pathway, starch and sucrose metabolism pathway, and GA pathway by KEGG analysis respectively. Noteworthy, data analysis revealed that 23 known tuber miRNAs belong to 11 miRNA families, and 50 novel miRNAs were identified. miRNA160, miRNA396, and miRNA535 may be involved in complex network to regulate cell division and differentiation in yam during its expansion stage. The integrated analysis of miRNA-mRNA identified to be preferentially expressed in hormone signaling in expansion stage, miRNA160 was down-regulated in expansion stage, ARF18 and ARF17 were up-regulated in auxin signal transduction of tuber expansion in yam, highlighting the involvement of miRNA-mRNA in the regulation the hormone. The transcriptome and miRNA datasets presented here identified a subset of candidate genes and miRNAs that are putatively associated with tuber expansion in yam, thus a hypothetical model of genetic regulatory network associated with tuber expansion in yam was put forward, which may provide a foundation for molecular regulatory mechanism researching on tuber expansion in Dioscorea species.
Aerodynamic characteristics of a rotorcraft airfoil designed for the tip region of a main rotor blade

A wind tunnel investigation was conducted to determine the 2-D aerodynamic characteristics of a new rotorcraft airfoil designed for application to the tip region (stations outboard of 85 pct. radius) of a helicopter main rotor blade. The new airfoil, the RC(6)-08, and a baseline airfoil, the RC(3)-08, were investigated in the Langley 6- by 28-inch transonic tunnel at Mach numbers from 0.37 to 0.90. The Reynolds number varied from 5.2 x 10(exp 6) at the lowest Mach number to 9.6 x 10(exp 6) at the highest Mach number. Some comparisons were made of the experimental data for the new airfoil and the predictions of a transonic, viscous analysis code. The results of the investigation indicate that the RC(6)-08 airfoil met the design goals of attaining higher maximum lift coefficients than the baseline airfoil while maintaining drag divergence characteristics at low lift and pitching moment characteristics nearly the same as those of the baseline airfoil. The maximum lift coefficients of the RC(6)-08 varied from 1.07 at M=0.37 to 0.94 at M=0.52 while those of the RC(3)-08 varied from 0.91 to 0.85 over the same Mach number range. At lift coefficients of -0.1 and 0, the drag divergence Mach number of both the RC(6)-08 and the RC(3)-08 was 0.86. The pitching moment coefficients of the RC(6)-08 were less negative than those of the RC(3)-08 for Mach numbers and lift coefficients typical of those that would occur on a main rotor blade tip at high forward speeds on the advancing side of the rotor disk.

Understanding the public attitudes to road safety. A review of the literature 2000-2009

This paper supports the conclusion of stage one of a project that will provide the Department for Transport (DfT) with an in-depth understanding of how the public engage with the issue of road user safety, to help inform development of the Government’s Post-2010 Road Safety Strategy. It presents an in-depth review of 72 research reviews, reports and journal articles relating to public attitudes to road user safety, concentrating on evidence from the UK dating from the year 2000 onwards. At the aggregate level there is high support from the public that behaving in a safe manner on the roads is important and increasing safety through various interventions, including enforcement, engineering and education, is seen as generally acceptable. For example, there is generally a high level of understanding that faster speeds are linked to collisions and high support for drink-driving laws, increasing 20mph zones in residential areas, traffic calming and speed cameras. However, closer inspection of the literature suggests some subtle differences both between and within individuals. A prevailing theme throughout this review has been the notion of a difference between the road user themselves and “other” road users. Overwhelmingly, there seems to be a consensus that drivers and pedestrians see themselves as competent and safe road users and other users of the road environment as more risky and dangerous. Hence, support for interventions is largely accepted as necessary for “other” road users rather than for themselves. In addition, the public’s conceptualisation of road user safety shows the social nature of appraising risk and the road user environment and consequently the impact of normative pressure, especially the influence of others, is evident in much of the research. Hence, distorted views on the behaviour of others towards safety and risk influence the public’s own behaviour. Another prevailing theme that emerges from the literature to date is that attitudes towards road user safety seem to vary within individuals over a period of time. Older and female road users have more safety orientated attitudes almost across all road user domains than younger and male road users, for example. In addition, attitudes vary depending upon the context of the research and of the researched. Hence, findings are different when investigating attitudes towards road user safety between a pedestrian and a driver. However, it must be remembered a driver can also be a pedestrian, cyclist or motorcyclist at other times. Research needs to understand road user attitudes in the context of an individual. Gaps have been identified for further research to be addressed at the latter stages of the research project.
Association of Cardio-Metabolic Risk Factors and Basic and Instrumental Activities of Daily Living Among Elderly People;Bushehr Elderly Health Program

Background: Iran's population is aging. One of the most common problems in Iranian public health is the high prevalence of cardio-metabolic risk factors. The purpose of this study was to investigate the relationship between cardio-metabolic and demographic risk factors and disability in people 60 years and older in Iran.Methods: Data from the Bushehr Elderly Health (BEH) program was used in the analysis. Demographic characteristics, as well as the history of diabetes and other chronic diseases, and smoking were measured using standardized questionnaires. Anthropometric measurements and laboratory tests were performed under standard conditions. Dependency was determined by the questionnaires of basic activities of daily living (BADL) and instrumental activities of daily living (IADL) using Barthel and Lawton scales respectively. Multiple logistic regression was used in the analysis.Results: Mean (Standard Deviation) of the participants’ age was 69.34 (6.4) years (range: 60 and 96 years), and 48.06% of the participants were men. After adjusting for potential confounders, being older, being female (OR (95%CI): 2.33 (1.89 - 2.86)), having a lower education level, a history of diabetes mellitus (OR: 1.43 (1.17 -1.74)) and past smoking (OR: 1.25 (1.00 - 1.55)), and no physical activity (OR: 1.54 (1.23 - 1.87)) were significantly associated with dependency in IADL. Also, being older and female (OR: 2.38 (1.85 - 3.03)), having a lower education level, no physical activity (OR: 2.17 (1.61 - 2.86)) and low daily intake of calories were associated with dependency in BADL.Conclusion: Age, gender, education level and physical activity are risk factors of the dependency in both of BADL and IADL in the elderly people. Diabetes mellitus and past smoking are risk factors of the dependency in IADL, and low HDL cholesterol and low daily intake of calories are risk factors of the dependency in BADL.

Towards maximising pupil endeavour : an enquiry into a learning approach centred on teamwork and simulation in the context of technology education

The enquiry originated from observations of a series of learning events which appeared to generate high levels of pupil endeavour. These events were typified by being residential, employing commercial simulation, teamwork and a suspended timetable which allowed long periods of concentrated work on a design task. Observations provided the Impetus for an enquiry Intended to illuminate the learning approach and the origins of this increased endeavour. This enquiry employed a series of case studies with a parallel literature survey. The pre-enquiry learning events are described and an impression of the factors Involved established. The evolving nature of the enquiry Is explained. A literature survey is made of the key factors. The methods employed, Including their limits and limitations, are described. The case studies are summarised and discussed In relation to the literature survey. Conclusions are drawn and suggestions for further research are made. The key findings are that the enquiry indicates high levels of endeavour are replicable, given understanding of the factors involved. Pupils' perceptions of the relevance of the events is high. Pupils tend not to adopt a competitive approach on an inter- team basis but do respond to deadlines. Pupils tend to develop cooperative management structures rather than establish leaders which are not seen as relevant. Endeavour Is maximised in teams which are selected to be heterogeneous In terms of gender, friendship groupings, subject expertise and ability. Positive synergy Is Identified In terms of endeavour but not the range and quality of design ideas. Teachers, whilst recognising the value of granting autonomy to teams, find it difficult to release control and Intervene only when necessary. The contributions to knowledge lie in the areas of designing In teams under competitive pressure; pupil team reaction to competition and the response of staff to working In these learning contexts
Predicting scale effects on floating offshore wind turbines

Floating wind turbines are becoming fashionable within the Renewable Energy world. In the last years MARIN has been involved in an increasing number of projects for the offshore wind industry. The complete simulation of a full-scale free-floating wind turbine under waves and winds using viscous-flow (Unsteady-Reynolds-Averaged-Navier-Stokes URANS) CFD codes is still nowadays very costly. However, CFD methods can be used in an efficient way for aerodynamic analysis. And they can be used rather to generate 2D input for BEMT design tools or for the real complete analysis of the wind turbine. In the present work CFD URANS code ReFRESCO is used for both purposes, having in mind the design of the new MARIN Stock (not Floating) Wind Turbine (MSWT), based on the well-known 5MW NREL full-scale turbine. Only open-water constant wind, fixed platform conditions are considered here. The objectives of the work presented are threefold: 1) the NREL 5MW baseline turbine is calculated using ReFRESCO both in full-scale and model-scale (Froude-scaling) conditions and the scale-effects studied and quantified; 2) the MSWT designed for thrust/performance-scaling is analyzed using CFD and validation against available MARIN experimental data is done; 3) in order to possibly further improve the MSWT design, the aerodynamic characteristics of its sections/foils are scrutinized by means of a full numerical study using ReFRESCO.
