Abstract:

ABSTRACT This study compared four different transformation techniques by applying a simple linear regression on raw and transformed data. The R2 of each model was obtained and a test on the significance of these R2 was carried out. Also, the rxy(coefficient of correlation) were also obtained. The data used is a secondary data consisting of 53years (1964-2016) of the infant mortality rate in Nigeria (https://www.ceicdata.com/en/nigeria/health-statistics/ng-mortality-rate-infant-per-1000-live-births). The rxy were also compared and the results, 95.8%, 95.8%, 96.2%, 93.0%, and 92.9% respectively. The R2 obtained for the raw data, logarithm, square-root, square and inverse are as follows: 91.8%, 91.7%, 92.5%, 86.6% and 86.4% respectively. However, the R2 obtained for the raw data, logarithm, square-root, square and inverse compete favourably but the performance of inverse transformation suits the data most in terms of model accuracy. Key Words: Transformation, Raw data, logarithm, square-root, square, inverse

Abstract:

The reliability of the equipment, the working environment, the effectiveness of maintenance, the operation techniques, the technical skills of Machinist, etc. all affect how well machining equipment performs. The consequences of equipment failure become more catastrophic as the size and variety of fabrication equipment keep growing. In order to locate the system's shortcomings and identify the parts or units with low reliability for the specified designed performance, reliability analysis is necessary. This research discusses the reliability analysis of the lathe machine. Four subsystems of the lathe machine are identified and root cause analysis was carried out for all subsystems failure modes. Minitab 19 was employed to estimate the parameters settings of certain probability distributions, which includes the Weibull, Exponential, Loglogistic and Lognormal distributions. According to findings of the analysis, the belt drive subsystem is critical to the reliability of the Lathe machine. The study also demonstrates how reliability analysis is valuable in determining inspection periods. Keywords: Reliability Analysis, Root Cause Analysis, Lathe Machine, Reliability importance, Minitab19

Abstract:

Abstract In this study, we define vedic cube as the layout of each digital root in a three-dimensional multiplication table. In order to discover the geometric patterns in vedic cube, we adopt two methods to analyze the digital root in a three-dimensional space. The first method is floor method, which divides vedic cube into several X-Y planes according to different Z values (floors) to analyze the geometric characteristics on each floor. The second method is symmetric plane method, which decomposes vedic cube by its main and secondary symmetric planes.

Abstract:

<strong>Background: </strong>Phenotyping of genotype-by-environment interactions in the root-zone is of major importance for crop improvement as the spatial distribution of a plant’s root system is crucial for a plant to access water and nutrient resources of the soil. However, so far it is unclear to what extent genetic variations in root system responses to spatially varying soil resources can be utilized for breeding applications. Among others, one limiting factor is the absence of phenotyping platforms allowing the analysis of such interactions.<strong>Results: </strong>We developed a system that is able to (a) monitor root and shoot growth synchronously, (b) investigate their dynamic responses and (c) analyse the effect of heterogeneous N distribution to parts of the root system in a split-nutrient setup with a throughput (200 individual maize plants at once) sufficient for mapping of quantitative trait loci or for screens of multiple environmental factors. In a test trial, 24 maize genotypes were grown under split nitrogen conditions and the response of shoot and root growth was investigated. An almost double elongation rate of crown and lateral roots was observed under high N for all genotypes. The intensity of genotype-specific responses varied strongly. For example, elongation of crown roots differed almost two times between the fastest and slowest growing genotype. A stronger selective root placement in the high-N compartment was related to an increased shoot development indicating that early vigour might be related to a more intense foraging behaviour.<strong>Conclusion: </strong>To our knowledge, RADIX is the only system currently existing which allows studying the differential response of crown roots to split-nutrient application to quantify foraging behaviour in genome mapping or selection experiments. In doing so, changes in root and shoot development and the connection to plant performance can be investigated.

Os 49 dentes de mandíbulas humanas maceradas com reabsorções de diferentes dimensões, simuladas na região apical e lingual, foram radiografados com variação de ângulos de projeção. A radiografias foram registradas a posteriori pelo programa Regeemy® e subtraídas pelo programa Image Tool®. A quantidade de ruído estrutural nas imagens subtraídas foi obtida pela mensuração da média e desvio-padrão dos níveis de cinza. Para avaliação do desempenho dos métodos de diagnóstico, pares de radiografias periapicais e imagens subtraídas foram apresentadas a 3 radiologistas. De acordo com os resultados, o ruído das imagens subtraídas de radiografias após variações de 10º e 20º do ângulo vertical e 10º horizontal e corrigidas a posteriori, foi significantemente maior que das imagens subtraídas de radiografias padrão, independente da região radiografada. Não houve diferença estatisticamente significativa entre os métodos na detecção de reabsorções apicais, independentemente do tamanho da lesão, assim como não houve diferença entre os métodos na detecção de reabsorções linguais de 1,2 mm ou mais. A SRD foi significantemente superior à radiografia digital para detecção de lesões linguais de cerca de 1 mm. Cavidades na superfície lingual de cerca de 0,5 mm não foram detectadas com precisão por nenhum dos métodos...

Forty nine teeth with simulated lingual and apical root resorptions of varied extension were x-rayed with different projection angles. The radiographs were registered a posteriori with Regeemy® software and subtracted with Image Tool® software. The amount of structural noise of the subtracted images was evaluated by measuring the mean and standard-deviation of their gray levels. The performance of each method of diagnosis was assessed by submitting pairs of periapical radiographs and the subtracted images to the evaluation of three oral radiologists. According to the results, the structural noise of subtracted images from radiographs with variations of 10º and 20º of vertical angle and 10º of horizontal angle was significantly higher than the obtained from the radiographs without angular variation, independently from the anatomic region of the image. There was no statistically significant difference between the methods on the detection of apical root resorptions independently from the size of the lesion as well as no statistically significant difference was found between the methods on the detection of lingual resorptions of 1.2mm or more. DSR was significantly superior to the digital radiographs on the detection of lingual lesions of around 1mm. Lingual lesions of around 0.5mm were not precisely detected by any of the methods. The inter- and intra-examiner agreements were substantial... (Complete abstract, click electronic access below)<br>Doutor

Abstract:

The development of digital networks has allowed the largest news media organisations to consolidate and centralise their publishing businesses in flourishing capital-city markets. This has resulted in a withdrawal from other less-viable markets, especially those which are geographically remote, and the subsequent emergence of the 'digital divide' with its attendant negative effects. This thesis proposes that the combination of technologies, theories and processes which has brought about the 'digital divide' can now be realigned to reverse those negative effects, and to enhance the possibility of focussed participatory communication taking place within and between those previously less-viable markets. This enhanced participatory communication - which I have named 'integrated journalism' - brings with it measurable and positive effects, generally known as community capacity building effects, which lead to better outcomes for the members of enhanced communities, a more innovative and flourishing approach to life and business, and a more innovative and forward-looking atmosphere within enhanced communities. Two new models are devised and presented: the first allows members of audience communities to learn and implement the process of publishing a community newspaper under the tuition of an experienced journalist; the second enables both journalists and audience members to measure and direct the effects of news publication within communities.

Abstract:

This exegesis explores the notions of production process paradigm shift through the analysis of digital technologies and their effect on the production of 'CruelUnusual'. Chapter one of this exegesis has introduced the research question with appropriate methodologies to explore the rhizomic possibilities of the use of new digital technology (DV, WWW & DVD) through the design of new structures and frameworks for audio-visual production. Chapter two will outline the traditional production process from the first steps of the pre-production phase, through to the shooting and editing of the film, to its final delivery on the screen. Chapter three will outline various new technologies to be explored and evaluated to assess their benefits to filmmakers in the creation of new production process paradigms. Chapter four of this exegesis presents an evaluation of the Rhizomic Production Process as a viable alternative to the traditional linear produc-tion process. The research data created during the production of the creative project is offered to sup-port arguments presented regarding the benefits of the Rhizomic Production Process. Chapter five will discuss the conclusions and implications discovered during the evalua-tion of the Rhizomic Production Process through the production of the creative project and suggest further possible directions.

Abstract:

This thesis presents an interactive computerised teaching suite developed for the design of combinatorial and sequential logic circuits. This suite fills a perceived gap in the currently available computer-based teaching software for digital logic design. Several existing digital logic educational software are available, however these existing programs were found to be unsuitable for our use in providing alternative mode subject delivery. This prompted the development of a Microsoft Windows TM tutorial suite, called WinLogiLab. WinLogiLab comprises of a set of tutorials that uses student provided input data, to perform the initial design steps for digital Combinatorial and Sequential logic circuits. The combinatorial tutorials are designed to show the link between Boolean Algebra and Digital Logic circuits, and follows the initial design steps: from Boolean algebra, truth tables, to Exact and the Heuristic minimisation techniques, to finally produce the combinatorial circuit. Similarly, the sequential tutorials can design simple State Machine Counters, and can model more complex Finite State Automata.

The certified thesis is available in the Institute Archives and Special Collections.<br>Cataloged from student-submitted PDF version of thesis.<br>Includes bibliographical references (p. 81-82).<br>The arrival of photons at a given location is a Poisson process with an associated shot noise which rises with the square root of the number of photons received. An analog-to-digital converter (ADC) with a square root transfer function can quantize photonic signals with LSB size kept constant with respect to the photon shot noise. In imaging applications, this can greatly reduce the number of bits needed to characterize a signal compared to a linear ADC without detrimental effects to image quality. Such a device, based on the Analogic MuSIC chip, was designed and tested for the needs of a medical computed tomography (CT) device. The experimental setup increases the MuSIC sampling frequency from 3kHz to 7kHz, while reducing the amount of data necessary for reconstruction. A constant quantization noise to photon shot noise ratio acceptable for CT is maintained by sizing each LSB to be one half the rms noise level. Results show an INL of 2.5 LSB, which is reduced to 0.27 LSB after a correction scheme.<br>by Matthew Bieniosek.<br>M.Eng.

Abstract:

>Magister Scientiae - MSc<br>Different pathology associated with impacted wisdom teeth in the oral cavity showed that it is prevalent and may lead to varied dental complications. This study adopted a descriptive cross-sectional retrospective analytical design in order to examine hard tissue features associated with the presence of impacted third molars in a random sample of 2998 digital panoramic radiographs (DPRs) of patients' records in Tygerberg Oral Health Centre, Faculty of Dentistry, University of Western Cape. The specific objectives of the study were to categorize the type of impactions in the DPRs of patients and to determine the prevalence of distal cervical caries (DCC) in second molars, any radiolucent (RL) /radiopaque (RO) lesions or external root resorption (ERR) complications associated with impacted wisdom teeth. Results of the pantomographs and clinical records of patients indicated that the most prevalent type of impaction (TOI) is Mesioangular (MA) Impaction (65%) followed by Horizontal (H) Impaction (17%), Vertical (V) Impaction (15%), Transverse (TVS) Impaction (2 %) and Distoangular (DA) Impaction (1.2 %), respectively. The least prevalent type was Inverted (INV) Impaction with a frequency count of 0.5%. The results further indicated varied dental complications resulting from impaction, ranging from ERR with a frequency of 3% of which 66.70% was associated with MA type of impaction, followed by H with a frequency of 26.7%. The association of Gender and RL/ RO lesions was significant (p-value=0.04) while association between DCC and types of impaction was also significant (p-value =0.0017). The study concluded that the high prevalence of MA among all populations and genders over the years may be related to the anatomical normal inclination of the third molars to the mesial surface. The low prevalence of DA observed in the study sample on the other hand might be attributable to gender and demographic factors. Lastly, this study has only one radiopaque lesion and the high prevalence of RL lesions in males and in the older age group suggests that these complications take a while to develop. Future research is needed to raise more awareness and encourage patients to seek treatment of symptomatic and asymptomatic third molars before complications arise.

Abstract:

Introdução: As reabsorções radiculares internas (RRI) são lesões de prognóstico difícil e o seu diagnóstico é baseado, principalmente, em exames de imagem. Tanto lesões pequenas quanto perfurações em lesões extensas são situações críticas e um desafio para o diagnóstico. As poucas pesquisas que investigaram a detecção de RRI e de perfurações causadas pelas mesmas, simularam as lesões com uso de brocas, criando cavidades com forma e limites definidos diferentes da realidade clínica. Assim, o objetivo deste estudo foi avaliar a capacidade diagnóstica das radiografias digitais, com diferentes filtros, em duas situações clínicas: na detecção de RRI pequenas; e na visualização das paredes dentinárias remanescentes e na detecção de perfurações em RRI simuladas, com desmineralização ácida. Materiais e métodos: Foram simuladas lesões de RRI com desmineralização ácida nos condutos radiculares de 42 dentes monorradiculares, seccionados no sentido coronal, reposicionados e colocados em alvéolos de uma mandíbula seca. Radiografias digitais com placas de fósforo (Vista Scan - Dürr Dental, Germany) com dissociação foram realizadas, em momentos diferentes para os objetivos, Obj.1: antes (GC) e após (GT) a simulação de RRI pequenas; Obj.2: após a simulação de lesões extensas com remanescente de parede dentinária (GC) e com perfuração da parede lateral da raiz (GT). Todas as imagens foram exportadas e 7 filtros de processamento foram aplicados para a análise mais a imagem original (sem filtro). Três examinadores utilizando uma escala Likert de 5 pontos avaliaram as imagens quanto: Obj.1, a presença/ausência de RRI; Obj.2, a presença/ausência de perfuração. O índice Kappa intra e inter-examinadores foi calculado para avaliar a reprodutibilidade. Testes de diagnóstico e AcROC foram calculados para cada grupo (GT e GC) e para cada filtro de imagem. A distância do escore determinado na escala até o valor do padrão-ouro foi utilizado para mensurar a certeza/incerteza no diagnóstico. Equações de Estimação Generalizadas (GEE) foram utilizadas para a análise estatística, com significância de 0,05%. Resultados: Valores moderados de Kappa-inter (0,403-0,620) e altos de intra-examinadores (0,757-0,915) foram observados. Para Obj.1: Maior percentual de acertos ocorreu no GC, significativamente (p<0,05). Imagens originais apresentaram maior sensibilidade e AcROC (0,595-0,750) e o filtro Endo apresentou maior especificidade (0,952), em relação às demais imagens, sem diferença estatística entre elas (p>0,05). Os filtros Inversion e Pseudo3D causaram maior incerteza no diagnóstico das RRI, estatisticamente significante para o GC com o filtro Pseudo3D (p<0,05). Para Obj.2: Imagens com o filtro Pseudo3D resultaram em mais escores de dúvida (73,5-78%), e maiores distâncias do padrão ouro, gerando maior incerteza no diagnóstico, significativamente (p<0,05), em relação aos demais filtros. Maior acROC (0,615) foi relacionada ao filtro Perio, sem diferença estatística (p>0,05). Maiores distâncias, refletindo maiores incertezas nos diagnósticos, foram observadas no GC para todos as imagens. O percentual de acerto foi menor conforme diminuiu a espessura da parede remanescente, com 31% de acerto para as espessuras de 0,2mm. Conclusões: Paras as lesões de RRI pequenas: os filtros Inversion e Pseudo3D são contraindicados, pois geram muit incertezas aumentando a probabilidade de erros de diagnóstico. Em casos de dúvida, a imagem sem filtro (Original) deve ser buscada, pois apresenta maior capacidade diagnóstica e permite maior certeza na avaliação. Para as lesões de RRI extensas, com suspeita de perfuração: o filtro Pseudo3D deve ser evitado pois gera maior incerteza no diagnóstico e filtro Perio deve ser incentivado, pois facilita a avaliação, aumentando as chances de diagnósticos corretos. Deve-se ter em mente que nos casos diagnosticados como perfuração, ainda pode existir uma camada de parede dentinária remanescente.<br>Introduction: Internal root resorption (RRI) are difficult to predict injuries and its diagnosis is mainly based on imaging studies. Both minor injuries as punctures in extensive lesions are critical situations and a challenge for diagnosis. The few studies that investigated the detection of RRI and punctures caused by them, simulated lesions with use of drills, creating cavities with different shape and defined limits of clinical reality. The objective of this study was to evaluate the diagnostic ability of digital radiographs with different filters in two clinical situations: small RRI detection; and in view of the remaining dentin walls and to detect perforations in RRI simulated with acid demineralization. Methods: RRI injuries were simulated with acid demineralization in root canals of 42 teeth monoradicular, sectioned coronally repositioned and placed in wells of a dry jaw. digital radiographs with phosphor plates (Vista Scan - Dürr Dental, Germany) and dissociation were taken at different times for the purposes, Aim 1: Before (CG=control group) and after (TG=test group) simulating small RRI; Aim 2: after simulation with extensive lesions reminiscent of dentinal wall (CG) and perforation on the lateral wall of the root (GT). All images were exported and 7 processing filters were applied to the analysis over the original image (no filter). Three examiners using a 5-point Likert scale images evaluated as Aim 1, the presence / absence of RRI; Aim 2, the presence / absence of perforation. The Kappa intra and inter-examiner was calculated to assess reproducibility. Diagnostic tests and AcROC were calculated for each group (CG and TG) and for each image filter. The distance determined score on the scale to the value of the gold standard was used to measure the certainty / uncertainty in diagnosis. Generalized Estimating Equations (GEE) were used for statistical analysis with significance level of 0.05%. Results: moderate values of Kappa-inter (0.403 to 0.620) and high intra-rater (0.757 to 0.915) were observed. For objective 1: A higher percentage of hits occurred in the GC, significantly (p <0.05). Original images showed higher sensitivity and AcROC (0.595 to 0.750) and Endo filter showed higher specificity (0.952), compared to other images, with no statistical difference between them (p> 0.05). The filter Inversion and Pseudo3D caused greater uncertainty in the diagnosis of RRI statistically significant GC with the filter Pseudo3D (p <0.05). For the purpose of 2: Images with the filter Pseudo3D resulted in more scores of doubt (from 73.5 to 78%), and greater distances from the gold standard, leading to greater uncertainty in the diagnosis, significantly (p <0.05) compared to other filters. Most acROC (0.615) was related to the filter Perio, with no statistical difference (p> 0.05). Greater distances, reflecting greater uncertainty in diagnosis were observed in the control group for all the images. The hit percentage was lower as decreased the thickness of the remaining wall, with 31% accuracy for thickness of 0.2 mm. Conclusions: Paras small lesions RRI: Inversion and the Pseudo3D filters are contraindicated because they generate too many uncertainties increasing the probability of misdiagnosis. In cases of doubt, the image without filter (Original) must be sought, because it has greater diagnostic capacity and allow greater certainty in the assessment. the extensive RRI injuries, suspected of drilling: the Pseudo3D filter should be avoided because it creates greater uncertainty in the diagnosis and filter Perio should be encouraged as it facilitates the evaluation, increasing the chances of correct diagnoses. It should be borne in mind that in cases diagnosed as drilling, there may still be a remaining dentin wall layer.

Abstract:

While current scholarly interest has assured Marshall McLuhan's (1911-80) foundational status as a media theorist, much room still exists for further exploration of his writings, which have taken on additional layers of significance in our contemporary digital moment. Holding that media were extensions of the human, McLuhan also posited that the human was a product of technology. Ranging across fields as diverse as art history, biotechnology, and beyond, this collection of essays considers McLuhan's ground-breaking approach within a number of new contexts and explores the distinguishing features of his media theory.

Abstract:

AbstractThe digital world has a strong tendency to let everything in its realm appear as resources. This includes digital public discourse and its main creators, humans. In the digital realm, humans constitute the economic end and at the same time provide the means to fulfill that end. A good example is the case of online public discourse. It exemplifies a range of challenges from user abuse to amassment of power, difficulties in regulation, and algorithmic decision-making. At its root lies the untamed perception of humans as economic and information resources. In this way, digital technology provides us with a mirror that shows a side of what we are as humans. It also provides a starting point to discuss such questions as who would we like to be – including digitally, which purpose should we pursue, and how can we live the digital good life?

Abstract:

Air safety investigators must seek out all available sources of evidence from an aircraft crash incident in order to make informed root cause determinations. This is especially important when the incident aircraft was not equipped with flight and voice data recorders. Previous investigations have utilized trajectory analysis methods as a technique to determine where debris items may be found on the ground after an in-flight breakup. Alternatively, if the ground placement of debris items is known, then the airspeed and heading of the aircraft may be back-calculated. In this paper, a probabilistic trajectory analysis is developed to infer crash debris initial conditions at time of impact. Digital methods including computational fluid dynamics have been employed to calculate debris item aerodynamic coefficients and probabilistic sampling techniques to determine a likely range of initial angles and initial velocities. Finally, two example cases are presented to illustrate application of the technique and its utility for design making with respect to crash investigation.

Abstract:

The evaluation of root crops is important for better understanding of the effects of plant nutrition and nutrient management in the soil. However, the studies and the root system of the culture are slow, require a long time and show low precision results. In this context, digital image processing can be an alternative. The objective of this study was to develop a computational method to assist in the evaluation of the surface area of soybean roots. It was initially developed in Java platform by providing the OpenCV library through the plug-in JavaCV. Then, after the manual count, the soybean root samples that have been scanned, were loaded into the software. The software developed results were correlated with the intersection of the line method. The correlation coefficient (R = 0.77) obtained by the software developed was on average good, compared to the métododa line intersection. Therefore, in general, the proposed method was necessary paraestimar the surface area of the soybean roots.

Abstract:

PT Chevron Pacific Indonesia (PT CPI) operates the Rokan block with 13,000 km pipeline length in Riau province. Oil theft attempts through illegal tapping is one of the challenges in operating Rokan block. PT CPI experienced 16 spill cases with a volume of 1,085.98 barrels in 2018-2019 as reported to The Government of Indonesia. The investigation using why tree method is conducted to identify the system level root causes described through tree branches. Five investigations in 2018-2019 reveal the repetitive root cause pattern. Significant root causes related to spill due to illegal tapping are key stakeholders’ engagement, surveillance resources, surveillance method and emergency response. Recommendations developed to these root causes create a comprehensive strategy to overcome spill due to illegal tapping. Comprehensive strategy by conducting continuous engagements to state government and local government, increasing personnel for surveillance resources, improving surveillance method and implementing thorough response has created significant impacts. Decreasing number of spill case in 2020 affects the revenue performance on financial aspect. Hiring local community for additional surveillance resources creates positive social impact for operation of PT CPI. Improved surveillance program shows sustained oil flow supporting the operation. Environmental impacts could be reduced by deploying response team immediately, recovering and cleaning the site according to regulation related to hazardous waste. Comprehensive strategy from PT CPI can be adopted by other Production Sharing Company (PSC) operators to maintain sustainability to deliver optimum production to meet the national target.

Abstract:

Abstract Plants are crucial to our lives because they provide us with building materials, oxygen, and food. A season’s crop yield can be significantly affected by local environmental factors. In particular, improving fundamental understanding of plant root interactions with their local soil environment, or rhizosphere, will help improve crop yield. Studying such interactions is challenging because roots are underground, making it difficult to observe interactions and to manipulate the local soil environment. The goal of this study was to develop an automated mini-channel platform to investigate how plant roots respond to changes in their environment using corn as a model plant. Considering the size of corn seedling roots, mini-channel devices were fabricated in soft lithography using master molds produced with a 3D printer and polydimethylsiloxane (PDMS). Our use of a 3D printer instead of photolithography allowed for a broader range of PDMS mold designs, such as including embedded rubber gaskets built into the mold. Then, corn seedlings were grown inside the transparent mini-channel devices, and they were found to consume an observable amount of nitrate over time. Image processing was employed to measure the contour length of the roots for quantitative characterization of root growth. Then, an automated platform was developed to measure the growth rate of the corn seedling roots and the consumed nitrate over time. The automated platform maintained the level of growth medium in the channel device, and was equipped with a digital camera to image the root growing in the channel, electrochemical sensors to measure changes in nitrate concentration in the channel, and sensors to measure temperature and humidity. Therefore, the platform could automatically measure root growth while simultaneously measuring root environment. The platform’s adaptable design, simple fabrication, and low cost make it simple to replicate and use to study different plants and environmental stimuli.

Full text

Abstract:

A low-cost multicamera Unmanned Aircraft System (UAS) is used to simultaneously estimate open-coast topography and bathymetry from a single longitudinal coastal flight. The UAS combines nadir and oblique imagery to create a wide field of view (FOV), which enables collection of mobile, long dwell timeseries of the littoral zone suitable for structure-from motion (SfM), and wave speed inversion algorithms. Resultant digital surface models (DSMs) compare well with terrestrial topographic lidar and bathymetric survey data at Duck, NC, USA, with root-mean-square error (RMSE)/bias of 0.26/–0.05 and 0.34/–0.05 m, respectively. Bathymetric data from another flight at Virginia Beach, VA, USA, demonstrates successful comparison (RMSE/bias of 0.17/0.06 m) in a secondary environment. UAS-derived engineering data products, total volume profiles and shoreline position, were congruent with those calculated from traditional topo-bathymetric surveys at Duck. Capturing both topography and bathymetry within a single flight, the presented multicamera system is more efficient than data acquisition with a single camera UAS; this advantage grows for longer stretches of coastline (10 km). Efficiency increases further with an on-board Global Navigation Satellite System–Inertial Navigation System (GNSS-INS) to eliminate ground control point (GCP) placement. The Appendix reprocesses the Virginia Beach flight with the GNSS–INS input and no GCPs.

Full text

Abstract:

In every school, dedicated teachers strive to support their students' unique learning journeys. Imagine a classroom where potential challenges are quickly identified and met with precise interventions. Imagine a school or school district where the many potential ways to solve problems can be quickly tested, and the best solutions rapidly scaled up across the district. We explore how this vision can become a reality through the integration of Improvement Science with SEERNet's data and research capabilities. Improvement Science offers a structured approach to identifying and solving problems. SEERNet—a network of digital learning platforms, researchers, and educators—provides a method to use evidence to compare alternative approaches to supporting students on the basis of detailed data from students’ experiences in digital learning platforms. However, this vision cannot be realized in isolation. Collaboration between researchers and practitioners is vital for improving student outcomes. Researchers contribute theoretical knowledge and empirical skills, while practitioners bring on-the-ground professional experience and knowledge about what works for their students. Working together, they can advance how educational technologies are used for student learning in ways that are research based, practical and relevant. This white paper explores how and why SEERNet could be combined with Improvement Science methodologies. We delve into the collaborative power of Networked Improvement Communities (NICs), a core method in Improvement Science. We then examine the dynamic interplay between SEERNet's approach and Improvement Science. A scenario illustrates how a school district could use Terracotta, a platform that enables research within a popular LMS, to address reading comprehension barriers in STEM subjects for English learners and students with disabilities. Researchers and teachers collaborate to test assignment modifications, such as adding text-to-speech tools and steps to clarify questions. Using iterative Plan-Do-Study-Act (PDSA) cycles, they refine these strategies based on data, resulting in improved outcomes. The paper concludes with five recommendations: fostering collaboration, enhancing data sharing, leveraging root cause analysis, implementing iterative improvements, and scaling successful interventions.

Abstract:

The Global Goal of ensuring inclusive and equitable quality education and promoting lifelong learning opportunities for all promotes equality in access to quality learning, supports economic development, improves health outcomes, empowers women and girls, and fosters global citizenship and peace. By reducing inequities in education, both in terms of access and quality, we can help to build a more equitable, prosperous, and sustainable world. This study provides a detailed examination of the progress of the Philippines in achieving Sustainable Development Goal 4 (SDG4) on quality education and lifelong learning opportunities for all. It sets the stage by outlining the Philippine educational policy landscape, including its legal and institutional frameworks. The analysis then progresses to a target-by-target review of SDG 4, highlighting the nation's accomplishments and ongoing challenges. Notable achievements include nearly universal primary education enrollment and increased secondary education participation. However, issues like high dropout rates and subpar learning outcomes remain. The Philippines has also seen growth in early childhood development (ECD) and pre-primary education enrollments, yet access for disadvantaged children is still limited. The country has policies to enhance access to affordable technical, vocational, and higher education, but the quality of these programs and their alignment with future skills needs improvement. Inclusive education initiatives exist, such as programs for learners with disabilities and indigenous communities, but challenges in ensuring universal quality education persist. A shift in education outcomes in favor of girls is observed, with boys now more likely to drop out than girls across various educational levels and girls doing better than boys in learning. While literacy rates appear high, the need to redefine literacy measurements, considering issues like digital skills, is evident. Progress in school infrastructure development is significant, especially with the K-12 rollout, but enhancing learning environments, including using technology for learning, remains crucial. The Philippines boasts a large teaching workforce, yet there is a pressing need to elevate teacher training quality and align it with future skill requirements. The study pinpoints critical improvement areas, including addressing the root causes of learning deficits, implementing an open data policy, and refining teacher training and workload. Concluding with a call to action, the study underscores the necessity of a comprehensive strategy to tackle educational challenges holistically, with integrated planning among the three main government agencies tasked to manage the sector. It suggests developing specific targets for inclusive quality education. This comprehensive review offers valuable insights and practical recommendations for stakeholders to ensure the Philippines fulfills its commitment to quality education for all by 2030.
