Abstract:

Aim: The aim of this study was to evaluate the efficacy of the IG-file, a new instrument designed for apical diameter gauging. Materials and Methods: After shaping with F1 Universal Protaper, 60 roots were randomly divided into two groups and assigned to two operators, One Expert in Endodontics (EO) and One Unexpert (UO). In each sample, after canal curvatures have been detected, the apical diameters were measured with the IG-file and the K-NiTi. The results were compared with the reference value obtained by retrograde apical gauging. The data were statistically analyzed. Results: Among 60 samples, 10% of errors were recorded when the IG-files were used; in the K-NiTi group the incorrect measurements were 70%. In both groups (expert and unexpert) the IG-file measurements were more accurate than the K-NiTi (90 vs 33 and 90 vs 26,7). The differences were statistically significant. In curved canals, the difference between measurement rates performed with both instruments was statistically significant (85,7% IG-file vs 28,6% K-NiTi) as well as for the samples without curvatures (92,3% IG file vs 30,8% NiTi file). In root canals without curvatures overestimation errors in K-NiTi file group are more frequent than underestimation errors. This difference was statistically significant. Conclusion: A proper gauging of the apical diameter has a key role in endodontic therapy; an incorrect measurement can lead to clinical failures. This “in vitro” study highlights that IG-file improves measurement accuracy independently from clinician experience. Furthermore, in curved canals, the IG-file is more accurate than K-NiTi.

Abstract:

ABSTRACT Aim To investigate the influence of cervical preflaring on apical file size determination using four different rotary instruments. Materials and methods Fifty root canals from extracted human maxillary premolars with complete root formation, straight roots were used for the study. Access opening was done and the working length established with 8 no K-file for each canal. Teeth were randomly divided into five groups of 10 canals. In Group 1- no preflaring was done and acted as control and in Groups 2, 3, 4 and 5 cervical and middle third preflaring of the root canals were done using Gates Glidden drills, Protaper instruments, Race instruments and Galaxy files respectively. After preflaring, the apical file size determination was done and the initial apical file (IAF) was fixed at the working length. Teeth were sectioned transversally 1 mm from the apex, with the binding file in position. The samples were imaged under stereomicroscope with 30× magnification. Root canal and file maximum diameters were recorded for each sample. The readings were subjected to analysis of variance test and Scheffe's multiple comparison test. Results Preflaring with Race instruments lead to most accurate determination of the IAF. It was followed by Protaper, Galaxy files and Gates Glidden drills. Conclusion Traditional method of apical size determination may lead to a substantial underestimation of actual canal size. Cervical preflaring increases the accuracy of apical size determination. Clinical significance Thus, cervical preflaring is recommended before selection of IAF as it increases the accuracy of apical size determination. How to cite this article Ashwini TS, Bhandari S.

Abstract:

In the project of China's First National Geographic Conditions Census, millions of sample data have been collected all over the country for interpreting land cover based on remote sensing images, the quantity of data files reaches more than 12,000,000 and has grown in the following project of National Geographic Conditions Monitoring. By now, using database such as Oracle for storing the big data is the most effective method. However, applicable method is more significant for sample data’s management and application. This paper studies a database construction method which is based on relational database with distributed file system. The vector data and file data are saved in different physical location. The key issues and solution method are discussed. Based on this, it studies the application method of sample data and analyzes some kinds of using cases, which could lay the foundation for sample data’s application. Particularly, sample data locating in Shaanxi province are selected for verifying the method. At the same time, it takes 10 first-level classes which defined in the land cover classification system for example, and analyzes the spatial distribution and density characteristics of all kinds of sample data. The results verify that the method of database construction which is based on relational database with distributed file system is very useful and applicative for sample data’s searching, analyzing and promoted application. Furthermore, sample data collected in the project of China's First National Geographic Conditions Census could be useful in the earth observation and land cover’s quality assessment.

Abstract:

Abstract Motivation The Oxford Nanopore Technologies (ONT) MinION is used for sequencing a wide variety of sample types with diverse methods of sample extraction. Nanopore sequencers output FAST5 files containing signal data subsequently base called to FASTQ format. Optionally, ONT devices can collect data from all sequencing channels simultaneously in a bulk FAST5 file enabling inspection of signal in any channel at any point. We sought to visualize this signal to inspect challenging or difficult to sequence samples. Results The BulkVis tool can load a bulk FAST5 file and overlays MinKNOW (the software that controls ONT sequencers) classifications on the signal trace and can show mappings to a reference. Users can navigate to a channel and time or, given a FASTQ header from a read, jump to its specific position. BulkVis can export regions as Nanopore base caller compatible reads. Using BulkVis, we find long reads can be incorrectly divided by MinKNOW resulting in single DNA molecules being split into two or more reads. The longest seen to date is 2 272 580 bases in length and reported in eleven consecutive reads. We provide helper scripts that identify and reconstruct split reads given a sequencing summary file and alignment to a reference. We note that incorrect read splitting appears to vary according to input sample type and is more common in ’ultra-long’ read preparations.

Abstract:

The study presented here demonstrates the benefits of using a repeatability file for near infrared (NIR) spectroscopy calibration development. Calibrations were developed from rapeseed samples of a narrow moisture content (2.5–6.0%) and used on a validation set with an extended moisture content (3.6–13.0%). The elevated moisture content of the validation samples led to increased standard errors of prediction ( SEP) for the calibrations predicting oil, protein, GSL and C18:1 content. Two methods were investigated to reduce the moisture sensitivity of the NIR spectroscopy calibrations: (a) the exclusion of water bands in the NIR spectral region during calibration development and (b) the use of a repeatability file as proposed by Westerhaus (1990). The increased SEPs could be decreased by up to 66% by either the exclusion of the water bands or the use of a repeatability file containing spectra of moist and dry samples. The best results were obtained with a repeatability file using spectra from a single sample. A spectral interpretation is given.

Abstract:

ABSTRACT Aim This study assessed the biocorrosive capacity of two bacteria: Desulfovibrio desulfuricans and Desulfovibrio fairfieldensis on endodontic files, as a preliminary step in the development of a biopharmaceutical, to facilitate the removal of endodontic file fragments from root canals. Materials and methods In the first stage, the corrosive potential of the artificial saliva medium (ASM), modified Postgate E medium (MPEM), 2.5 % sodium hypochlorite (NaOCl) solution and white medium (WM), without the inoculation of bacteria was assessed by immersion assays. In the second stage, test samples were inoculated with the two species of sulphur-reducing bacteria (SRB) on ASM and modified artificial saliva medium (MASM). In the third stage, test samples were inoculated with the same species on MPEM, ASM and MASM. All test samples were viewed under an infinite focus Alicona microscope. Results No test sample became corroded when immersed only in media, without bacteria. With the exception of one test sample between those inoculated with bacteria in ASM and MASM, there was no evidence of corrosion. Fifty percent of the test samples demonstrated a greater intensity of biocorrosion when compared with the initial assays. Conclusion Desulfovibrio desulfuricans and D. fairfieldensis are capable of promoting biocorrosion of the steel constituent of endodontic files. Clinical significance This study describes the initial development of a biopharmaceutical to facilitate the removal of endodontic file fragments from root canals, which can be successfully implicated in endodontic therapy in order to avoiding parendodontic surgery or even tooth loss in such events.

Abstract:

Today, malware authors not only write malicious software but also employ obfuscation, polymorphism, packing and endless such evasive techniques to escape detection by Anti-Virus Products (AVP). Besides the individual behavior of malware, the relations that exist among them play an important role for improving malware detection. This work aims to enable malware analysts at F-Secure Labs to explore various such relationships between malicious URLs and file samples in addition to their individual behavior and activity. The current detection methods at F-Secure Labs analyze unknown URLs and file samples independently without taking into account the correlations that might exist between them. Such traditional classification methods perform well but are not efficient at identifying complex multi-stage malware that hide their activity. The interactions between malware may include any type of network activity, dropping, downloading, etc. For instance, an unknown downloader that connects to a malicious website which in turn drops a malicious payload, should indeed be blacklisted. Such analysis can help block the malware infection at its source and also comprehend the whole infection chain. The outcome of this proof-of-concept study is a system that detects new malware using graph modelling to infer their relationship to known malware as part of the malware classification services at F-Secure.
Idag, skadliga program inte bara skriva skadlig programvara men också använda förvirring, polymorﬁsm, packning och ändlösa sådana undan tekniker för att ﬂy detektering av antivirusprodukter (AVP). Förutom individens beteende av skadlig kod, de relationer som ﬁnns mellan dem spelar en viktig roll för att förbättra detektering av skadlig kod. Detta arbete syftar till att ge skadliga analytiker på F-Secure Labs att utforska olika sådana relationer mellan skadliga URL: er och ﬁl prover i Förutom deras individuella beteende och aktivitet. De aktuella detektionsmetoder på F-Secure Labs analysera okända webbadresser och ﬁl prover oberoende utan med beaktande av de korrelationer som kan ﬁnnas mellan dem. Sådan traditionella klassiﬁceringsmetoder fungerar bra men är inte effektiva på att identiﬁera komplexa ﬂerstegs skadlig kod som döljer sin aktivitet. Interaktioner mellan malware kan innefatta någon typ av nätverksaktivitet, släppa, nedladdning, etc. Till exempel, en okänd loader som ansluter till en skadlig webbplats som i sin tur släpper en skadlig nyttolast, bör verkligen vara svartlistad. En sådan analys kan hjälpa till att blockera malware infektion vid källan och även förstå hela infektion kedja. Resultatet av denna proof-of-concept studien är ett system som upptäcker ny skadlig kod med hjälp av diagram modellering för att sluta deras förhållande till kända skadliga program som en del av de skadliga klassiﬁcerings tjänster på F-Secure.

Abstract:

This thesis describes a simultaneous fit to all five of the far detector oscillation samples analysed to date (FHC/RHC 1Rmu, FHC/RHC 1Re and FHC nue CC1pi+) using T2K data taken from 2009-2017 with \sci{1.47}{21}~POT in neutrino mode and \sci{0.76}{21}~POT in antineutrino mode. The aim of this analysis is to search for CP violation by setting limits on \dcp and measure the oscillation parameters \sonethree, \stwothree and \Dm232. The T2K (Tokai to Kamioka) experiment is a long-baseline accelerator neutrino oscillation experiment that is designed to make precision measurements of neutrino oscillation by observing numu disappearance and nue appearance. A numu beam is produced using a 30 GeV proton beam at the J-PARC and is detected by the near detector complex, ND280, and by the far detector, Super-Kamiokande, which is 295 km away from J-PARC. The far detector and one of the near detectors are located in an off-axis direction to the neutrino beam centre, resulting a narrow neutrino energy peak of 0.6 GeV and where the numu survival probability is expected to be minimal (or maximal nue appearance probability). The neutrino fluxes and their uncertainties at the near and far detector are predicted by the Monte Carlo simulation tuned with data from external hadron production experiments. The uncertainties of the neutrino flux parameters and certain neutrino interactions parameters at the far detector are reduced by the measurement at the off-axis near detector. Since the last analysis there has been improvement to event reconstructions at SK which results in 20% increase in nue increased purity in the 1R muon samples. Using data taken from 2009-2017, we observed 240 mu-like, 74 e-like, 15 nue CC1pi+ -like events in neutrino mode, and 68 mu-like, 7 e-like events in antineutrino mode. Confidence intervals for delta CP are produced using the Feldman-Cousins method, and confidence intervals of the other oscillation parameters are produced using the constant delta chi square method. The best-fit oscillation parameter values are found to be consistent with previous official results while giving tighter constraints. There is a first indication of CP conservation in neutrino sector excluded at 2 sigma level. The results are also presented showing the correlations that exist between the oscillation parameters.

Abstract:

Recent observations have suggested that the C III] lambda 1907/1909 emission lines could be alternative diagnostic lines for galaxies in the reionization epoch. We use the F128N narrowband filter on the Hubble Space Telescope's (HST) Wide Field Camera 3 (WFC3) to search for C III] emission in a sample of five galaxies at z = 5.7 in the Subaru Deep Field and the Subaru/XMM-Newton Deep Field. Using the F128N narrowband imaging, together with the broadband imaging, we do not detect C III] emission for the five galaxies with JAB ranging from 24.10 to 27.00 in our sample. For the brightest galaxy J132416.13+274411.6 in our sample (z = 5.70, J(AB) = 24.10), which has a significantly higher signal to noise, we report a C III] flux of 3.34 +/- 1.81 x 10(-18) erg s(-1)cm(-2), which places a stringent 3 sigma upper limit of 5.43 x 10(-18) erg s(-1)cm(-2) on C III] flux and 6.57 angstrom on the C III] equivalent width. Using the stacked image, we put a 3 sigma upper limit on the mean C III] flux of 2.55 x 10(-18) erg s(-1) cm(-2) and a 3 sigma upper limit on the mean C III] equivalent width of 4.20 angstrom for this sample of galaxies at z = 5.70. Combined with strong C III] detection reported among high-z galaxies in the literature, our observations suggest that the equivalent widths of C III] from galaxies at z > 5.70 exhibit a wide range of distribution. Our strong limits on C III] emission could be used as a guide for future observations in the reionization epoch.

Abstract:

This study explored psychopathic personality traits among a non-criminal, college undergraduate sample. Much research has been done on conceptualizing the construct of psychopathy, but this work has been conducted primarily with incarcerated individuals using a structured interview, The Psychopathy Checklist – Revised (PCL-R; Hare, 1991, 2003). The goal of the current study was to assess psychopathic traits among non-criminal individuals using The Self-Report Psychopathy Scale - Version Four (SRP-IV; Paulhus, Neumann, & Hare, in press), and compare how SRP-IV scores were associated with a well recognized semi-structured interview for psychopathy, The Psychopathy Checklist – Screening Version (PCL: SV; Hart, Cox, & Hare, 1995). The study also examined whether psychopathic personality traits could be predicted using a measure of normal-range personality, based on the five-factor model (FFM; Digman, 1990), and a measure developed by Loevinger (1976) related to ego development. Five-Factor Model Rating Form (FFMRF; Mullins-Sweat, Jamerson, Samuel, Olson, & Widiger, 2006) scores and Total Protocol Ratings (TPR score) on the Washington University Sentence Completion Test (WUSCT; Hy & Loevinger, 1996) were used to predict psychopathy scores. Correlations of SRP-IV scores and PCL: SV scores with FFMRF scores and WUSCT TPR scores were also examined for their uniformity. As predicted, there were significant, negative correlations between FFM domains, Agreeableness and Conscientious, and SRP-IV scores, as well as significant, negative correlations between WUSCT TPR scores and SRP-IV scores. These correlations ranged from small to strong for both SRP-IV overall scores and for SRP-IV factor scores (i.e., Interpersonal Manipulation, Callous Affect, Erratic Lifestyle, and Criminal Tendencies). Additionally, FFM domain scores and WUSCT TPR scores significantly predicted SRP-IV scores. FFM domains, Agreeableness and Conscientiousness, and WUSCT TPR scores, were the strongest predictors of SRP-IV scores. Similar results were found when FFM domain scores and WUSCT TPR scores predicted SRP-IV factor scores. Results also indicated Agreeableness and Conscientious explained an additional 24% of the variance in psychopathy scores, after controlling for WUSCT TPR scores. Conversely, WUSCT TPR scores explained an additional 5% of the variance in psychopathy scores after controlling for Agreeableness and Conscientiousness. Finally, as predicted, the differences in correlations between psychopathy scores (i.e., PCL: SV, SRP-IV), and Agreeableness, Conscientiousness, and WUSCT TPR scores were not statistically significant providing evidence that correlates of psychopathic traits can be measured among non-criminal individuals using a self-report measure, the SRP-IV, and that these findings are concordant with those based on a standardized structured assessment for psychopathy. Limitations of the study, implications, and recommendations for future research are also discussed.

Abstract:

The need for an improved understanding of the influence of sample scale on the compressibility behaviour of fine-grained soils is crucial in many applications, such as roads, embankments and foundations. The effect of sample scale represents a challenge when obtaining engineering parameters in the laboratory compared to those obtained in the field. This research therefore aimed at contributing to existing knowledge through both experimental and numerical studies. The experimental study was completed via a series of consolidation tests on fully saturated fine-grained soil (i.e. kaolin clay) at various sample scales, which were subsequently explored analytically using the finite element software PLAXIS 2D. This type of clay was chosen as it is easily sourced and well known. A Scanning Electron Microscope (SEM) and X-Ray Diffractometer (XRD) were employed in studying the micro-structure of the soil. The Oedometer apparatus was used to obtain the combined effect of sample scale and initial moisture content on the compressibility parameters of kaolin clay. Compressibility parameters such as coefficient of consolidation (cv), compression index (cc) and coefficient of volume compressibility (mv) were also investigated in this study. Three different methods were used to obtain cv: Casagrande, Taylor’s and Inflection methods. The sample scales were divided into three categories: soil sample height, diameter and diameter to height (D/H) ratio scale. Particular attention was given to the D/H ratio effect on the compressibility parameters due to the frictionless boundary conditions, and sample diameter scale due to drainage path length. Based on the experimental data, Taylor’s method was considered more reliable in deriving cv as compared to the Casagrande and Inflection methods, due to the end of primary consolidation (EOP) observed at all sample scales. It was also observed that on average, sample scale has an effect on cv with a correlation factor of 0.451 and that friction was reduced by 35%. The effect of sample scale on cc and mv was found to be insignificant. The investigation also showed a correlation factor between the initial moisture content and cv of 0.546 and, 0.162 and 0.026 for cc and mv respectively. The new proposed model developed in PLAXIS 2D was found to show no significant difference with the laboratory data except where the calculated coefficient of permeability was used. A new proposed model was developed in PLAXIS to further study the effect of sample diameter scale on the behaviour of fine-grained soils.

Abstract:

AbstractThis chapter discusses in detail the procedure followed to identify a 1-in-10 sample of persons born between 1870 and 1899 who resided in the United States at the time of their death at ages 105–109 for men and 108 or 109 for women. We tabulate the characteristics of these “semi-supercentenarians” and offer some observations about the level of their mortality. The procedure for identifying semi-supercentenarians consists of (1) casting a net to find candidates and then (2) determining for which candidates can both date of birth and date of death be validated. The net used to find candidates in the United States is different from the nets typically used in other counties: in the United States we use the file of enrollments in the federal government’s Medicare health insurance program. Some of the information needed for the verification step comes from another administrative file – the Social Security Administration’s file of applications for a new or replacement social security card. Verification of the date of death is accomplished by querying the National Death Index. Dates of birth are verified by using online resources to access the records of several censuses conducted many decades earlier.

Abstract:

Abstract In this paper, a novel method is proposed for the prototyping of digitized data by means of rapid prototyping technologies without constructing a CAD model. Firstly, an optimized STL file (the de facto file format for rapid prototyping machines) is constructed directly from digitized part data. In order to reduce storage space and increase computational efficiency for subsequent processes such as slicing, significant data reduction can be achieved at users’ discretion by deleting data points in planar and near planar regions. Points around the ‘blank region’ left by deleted triangles are linked through re-triangulation to form triangular facets obeying STL file rules. To obtain optimized re-triangulation result, a genetic algorithm (GA) is developed and implemented. Finally, experiments on different amount of data reduction over a digitized sample are conducted with satisfactory results.

Abstract:

Abstract Transmission electron microscopy (TEM) sample can be routinely made at a sub 30nm thickness and specific features in semiconductor device design are on the order of 30nm and smaller. As a result, small changes in pattern match registration can significantly influence the success or failure of proper TEM sample placement as an approximately 15nm shift in lamella placement can easily cause the sample to be off the feature of interest. To address this issue, design based recipe writing is being developed on a dual beam focused ion beam platform. The intent is to have the tool read a GDS file and pattern match the design information to physical wafer images in a similar fashion to state-of-the-art critical dimension scanning electron microscopy operation. While the results are very encouraging, more work needs to be done to ensure a TEM sample of approximately 30nm thickness is placed at the desired location.

Abstract:

We can start talking about the COVID-19 pandemic as an unprecedented shock that has required unique responses from many corporations. Understanding how they have responded is of first-order importance for the fields of corporate governance, corporate finance and stewardship. While some insights begin to emerge, others will take time and depend on more complete data sets to become available, such as financial statements and governance records for 2020. Such data typically come from annual reports and proxy statements. US companies with an end of the fiscal year on December, 31 hold their annual meetings in the spring. They typically file their annual reports by the end of March, but in 2019, some 30 percent of the 7,000 reports were filed in April and later. While firms also publish quarterly data, most release comprehensive annual data only 90 days after their fiscal year end, so the earliest date that a large sample of data on US firms will be available is April 2021. These dates may be similar or even later for firms in other countries

Abstract:

Abstract Particle Size Analysis (PSA) of formation or produced sand is an important process in oil and gas exploration and production. This information is required to design downhole sand control, surface sand monitoring and removal systems, and to predict erosion in completion and production systems. A major operator in Malaysia required PSA data as well but found it a challenge as their wells, located offshore in Field Z, contain high amounts of contaminants such as TENORM, Mercury and Hydrogen Sulphide (H2S). Manually collecting produced sand samples was deemed too hazardous to people and the asset thus a closed loop Online Sand Sampling and PSA package was developed and deployed offshore. Samples were taken directly off flowline sample points, flowed through an online PSA system and continued its flow path to a closed loop drain line. The system therefore collected liquid, gas, and sand samples without any need for manual handling thereby eliminating exposure of harmful substances to personnel. A field laptop, running propriety software, connected via ethernet cable to the PSA system continuously measure and record the size of sand particles as they flow through the said system. This allowed the offshore execution team to view and record particle size data in real time. Data collated was available for further analysis onshore because the file format of the PSA software allows play back to refine particle images captured during the sampling operation. This was completed for 32 wells with the majority of the sampling providing good clear particle size information. Results were re-run and analysed again onshore by a sand management technical team from both the operator and service provider. The results were comparable to lab analysed samples of commonly used Laser Particle Size Analysis (LPSA). Therefore this first of its kind method provides a novel way for operaters to sample sand and solids in hazardous and also non hazardous environments.

Abstract:

Abstract The Initial Graphic Exchange Specification (IGES) for design data and the EIA standard M and G Codes for Numerically Controlled machines (N/C) is used to develop an automated interface between existing computer aided design systems and N/C manufacturing systems. The Flexible Manufacturing Protocol, developed at the University of Maryland, outlines such an interface to control automated manufacturing cells used for prototyping quick design changes. This paper demonstrates one application of the protocol, developing an automated IGES to CNC interface to control a 3 axis CNC machining center given the geometric representation of the part in IGES format. Wireframe representations of 2-1/2 dimensional parts, composed of linear elements, are the primary tools used for design representation. The automated production of the sample part, presented in this paper, demonstrates that rapid prototyping is possible using an IGES design data file as input to the protocol.

Abstract:

We present a method for data acquisition and calibration of digital accelerometers which is being developed within the EMPIR Met4FoF project based on STM32 microcontrollers. Unlike analog sensors, some MEMS sensors with digital interface generate the sample clock themselves. For a dynamic calibration the exact knowledge of the sample times is essential. Therefore, an interrupt controlled data acquisition based on hardware timers with absolute time stamping was implemented. These routines are generic and can be used both for sensors that perform the measurements automatically, or for sensors whose data acquisition is requested by a hardware or software interrupt. The synchronization of the hardware timer with the absolute time is done via GNS time services or another PPS time source. The data is transferred from the microcontroller via ethernet to a host PC, which is to provide an OPC-UA interface and thus enables simple integration of the sensor system into larger measuring systems, like existing calibration setups. In addition to the acquisition of raw data for sensor calibrations, the system consisting of microcontroller and driver on the host system is also intended to provide dynamic measurement uncertainties. In addition, information about the calibration and the status of the sensor should be available on the system. The calibration data should be stored inform of a signed xml file on the microcontroller. In addition to this static information, the system should also record dynamic information about the status of the sensor, such as operating time, exceeding of measuring ranges, min and max temperature during operation.

Abstract:

Abstract Release of toxic, flammable and/or explosive materials into the atmosphere is extremely dangerous. If an ignition source is found, the resulting fire can often be devastating. Information, analysis and calculations of fire dynamic phenomena can assist in understanding and applying scientific information to real-world fire situations. Fire dynamicists can develop an appreciation for technical/scientific understanding of the phenomena and its applicability to real-world practical down-to-earth situations. Some sample calculations are exhibited to illustrate several aspects of fire behavior.

Abstract:

Abstract With mobile autonomous robots on the rise, data structuring and algorithm design plays a significant role in how fast data can be parsed and processed. With robotic systems that are decreasing in size and increasing with complexity, the speed at which data can be processed from multiple sources is crucial to how the system as a whole works. This paper plans to show the difference between certain computational algorithm complexities, both time and space complexity, in order to demonstrate the key ideas in data parsing for systems where computational time of an algorithm can affect the outcome performance of a robot dramatically. The algorithmic types being analyzed in this paper are in relation to a 3D LIDAR scanner in order to produce a point cloud as the output from pre-recorded files. Trigonometric calculations will need to be done in order to produce this output and each file used will be verified using a program supplied from the manufacturer of the LIDAR, Velodyne, in order to ensure the data is being read correctly. The sample data consists of two specific recorded sets, a loading bay and a downtown urban city. Each of data set covers the two configurable outputs, a 20 Mhz Dual Return mode and a 10 Mhz Single Return mode, providing a reasonable range in terms of size in bytes. This paper will show various levels of optimization in areas of trigonometric functions, specifically sine and cosine, algorithmic design, memory safety and defragmenting, and pointer manipulation in order to produce a robust, complex yet ideal algorithm for loading large sets of data rapidly and quickly while holding the level of reliability high. All software written in this paper intends to be natively implemented, meaning no operating system specific external binaries will be used for the end product.

Abstract:

The Computerized Delivery Sequence (CDS) file contains listings for nearly all addresses in the United States. Survey researchers use the CDS as a sampling frame from which to draw an address-based sample (ABS). More than 700,000 addresses on the CDS are marked as drop points, which are mail receptacles shared by multiple housing units (drop units). Drop points are a challenge to sample and present a potential source of error because of their "one-to-many" relationships. Several techniques have been developed to overcome this challenge, including deleting them from the frame or sampling all units at a given drop point. This paper serves as an introduction to these challenges, discusses the pros and cons to each "solution," and provides a list of best practices.

Abstract:

This report presents an early assessment of the impacts of the COVID-19 pandemic on agricultural commercialisation, food and nutrition security, labour and employment, and poverty and well-being in rural Nigeria. Data was collected from a stratified random sample of 110 respondent households drawn from five Local Government Areas (LGAs) in Ogun (Ijebu East, Obafemi Owode, and Imeko Afon) and Kaduna (Chikun and Soba) States. At the time of the survey, these LGAs had reported a small number of COVID-19 cases. The survey data is complemented by insights from five in-depth key informant interviews conducted in the LGAs. The APRA COVID-19 data collection will be carried out over three rounds. This report presents insights obtained from the first round implemented during mid-July 2020.
