Abstract:
OBJECTIVE: The objective of this study was to compare the measurements of electronic and radiographic method of working lengths calculation with actual working length of root canals. Precise working length determination is the most important part for successful root canal procedure. The most commonly used methods to determine the working length in root canal treatment are radiography and electronic apex locator. METHODOLOGY: A cross sectional study was done over a period of 06 months in the Department of Operative Dentistry, Fatima Memorial Hospital, Lahore. Sixty patients who were recommended extraction of their premolar teeth with sixty canals were selected by convenience sampling. The Root ZX* apex locator was used to determine electronic working length exactly identifying the apical constriction. Reference points were identified and radiographic working length were determined 1mm short of radiographic apex. The teeth were extracted along with file cemented before extraction inside root canal. The actual length of the root canal was then calculated using the same files and reference point with 3.5X magnification. Pearson chi square test was applied to compare the apex locator and digital radiographic measurement with actual working length. RESULTS: The Root ZX® apex locator was 95% accurate to identify the apical constriction as compared 70% accuracy given by radiographs within 0.5 mm of the apex. CONCLUSION: Electronic apex locator was more accurate as compared to digital radiography in working length determination.

Abstract:
The paper concerns with a method based on Microsoft Visual Studio for processing the image received from the vision camera working on the gripper of the librarian robot. Based on the information converted from the accurate image, the gripper has to identify the book on the bookshelves. Moreover, the outer edges are the most important due to the working area required by the fingers. Meantime, the method should analyze the outer edge on the top too, so that the gripper should have enough room for working by pushing up the book. We have used the dynamic method for setting aside the computer memory. The image processing was focused on improving the contrast quality due to its importance for setting up the outer edges of the book, which should be retrieved.

Abstract:
The purpose of the present study was to examine working memory (WM) capacity, lexical access and phonological skills in 19 children with cochlear implants (CI) (5;7-13;4 years of age) attending grades 0-2, 4, 5 and 6 and to compare their performance with 56 children with normal hearing. Their performance was also studied in relation to demographic factors. The findings indicate that children with CI had visuospatial WM capacities equivalent to the comparison group. They had lower performance levels on most of the other cognitive tests. Significant differences between the groups were not found in all grades and a number of children with CI performed within 1 SD of the mean of their respective grade-matched comparison group on most of the cognitive measures. The differences between the groups were particularly prominent in tasks of phonological WM. The results are discussed with respect to the effects of cochlear implants on cognitive development.

Abstract:
The effects of caffeine (250 mg) and placebo on healthy controls were studied in a double-blind, cross over study on 24 healthy subjects who performed a working memory n-back task. Reaction time and accuracy levels were tested using the n-back working memory measure in cognitive neuroscience. An experimental study tested on the 1, 2 and 3-back tasks under the placebo/coffee condition. Based on the empirical results obtained in this thesis it can be concluded that changes produced by caffeine ingestion support the hypothesis that caffeine acts as a stimulant. However, it cannot be proven that the stimulant translates into enhanced motor processes with an improvement in performance.

Recently, industrial dual-arm robots have gained attention as novel tools and we therefore focus on them to flexible control both the linear motion and the rotational motion of a working plate. However, it is difficult to measure the synchronous accuracy of two rotary axes without high accuracy gyro sensor. Thus, we proposed a novel method to measure it with a ball, which keeps a ball rolling around a circular path on it by dual-arm cooperative control. As a result, we demonstrated this method made it feasible to estimate the synchronous accuracy of two rotary axes of working plate.

Corrosion resistance and soldering tendency of different materials in moltenAl–Si–Cu alloy were studied. Hot-working tool steel, plasma nitrided steel andduplex layers with CrN, TiAlN, TiAlSiN and CrAlN top coatings, which wereproduced to various degree of surface roughness, were covered by the study.An ejection test was employed for investigation of the concerned phenomena.The ejection test was improved in order to increase its accuracy and thereliability of process simulation. Samples were examined in both short andextended periods of contact (5 and 20 min) with liquid casting. Castingsolidification was extended in order to intensify the corrosion effects. Contraryto common findings, it was found that the ejection force of the investigatedmaterials does not depend on their chemical composition. For the coatedsamples, a pronounced dependence of the ejection force on the surfaceroughness was found. The ejection force increases with decrease in surfaceroughness. All investigated coatings are prone to mechanical soldering by Al–Si–Cu alloy. Still, their corrosion resistance substantially exceeds the corrosionresistance of steel and plasma nitrided layer. Longer exposure of coatedsamples to cast alloy induced lower ejection forces, which is a consequenceof coatings oxidation. It was found that the investigated coatings are inert toliquid aluminium. However, the underlying material undergoes oxidation andcorrosion through coating growth defects. The findings concerning the wearmechanisms of protective layers support further development of duplex layersintended for die casting tools protection.

The existing ceramic laser rapid prototyping apparatus in our laboratory includes three systems which are layer casting system, laser scanning system and control system. When using current paving mechanism of layer casting system, the multi-hole distributor will feed a bundle of slurry in front of the scraper, and make a lot of waste. Beside this, the flow rate from each hole was not very equally. The bundle of slurry moves with the scraper during casting, a lot of liquid infiltrates into the dried green block. Thin layer cracks when liquid infiltrating depth over the Critical Saturated Thickness. So the first aim of this study is to improve the paving mechanism. To make the flow rate from each hole more equally, using electric circuit simulation and analyzing the flow rate of the multi-hole distributor. To adjust the XY linear table simple and efficient in the future. Build a measurement method is necessary. So the second aim of this study is to build a measurement system on a linear motor XY table. Calculate the position and contour errors by measuring accuracy. In the future, developing and adjusting linear motor could be more precisely by using this measurement system.

This study examines the relation among directors or financial managers with working experience of CPA firms, the accuracy of financial forecast, and earnings management. We focus on the following three issues: 1. The relation between directors or financial managers with working experience of CPA firms and earnings management. 2. The relation between the accuracy of financial forecast and earnings management. 3. Whether the companies with directors or financial managers who had working experience of CPA firms used higher extent of earnings management to make the financial forecast. In this study, we use the discretionary accruals (DA) to measure the extent of earnings management, and the forecast error ratio (FER) for measuring the accuracy of financial forecast. This study includes all firms which announced financial forecasts and listed in Taiwan Stock Exchange and Over-the-Counter from 2003 to 2005 in the sample. The substantial evidence finds after the analysis, when DA is larger than zero, the companies with directors or financial managers who had working experience of CPA firms had higher extent of earnings management upwards. When DA is less than zero, there is nothing significantly different between the companies with directors or financial managers who had working experience of CPA firms and other firms. No matter the actual earnings is higher or lower than forecasted earnings, DA upward and downward has different impacts on FER. DA upward shows no significant influence on FER. However, DA less than zero makes the financial forecast less accurate. Besides, the companies with directors or financial managers who had working experience of CPA firms does not significantly had lower FER than other firms. When the financial forecast is underestimated, the companies with directors or financial managers who had working experience of CPA firms has lower accuracy of financial forecast than other companies which use the same extent of DA. When the forecasted earnings is higher than the actual earnings, the companies with directors or financial managers who had working experience of CPA firms are not significantly different from other companies in FER, no matter DA is upward or downward.

Accurate determination of working length during endodontic therapy is critical in achieving a predictable and successful outcome. Working length is determined by the use of electronic apex locators, tactile perception, knowledge of average tooth lengths and dental radiography. Due to the increasing use of digital radiography in clinical practice, a comparison with conventional film in working length determination is justified. The purpose of this study is to determine if there is a difference between Schick digital radiography and Kodak Ultra-speed film in the accurate determination of working lengths when vertical angulation of the object is variable. Twelve teeth with #15 K-flex files at varying known lengths from the anatomical apex were mounted in a resin-plaster mix to simulate bone density. A mounting jig for the standardization of projection geometries allowed for exact changes in vertical angulation as it related to the object (tooth) and the film/sensor. Each tooth was imaged using Schick CDR and Kodak Ultra-speed film at varying angles with a consistent source-film distance and exposure time. Four dental professionals examined the images and films independently and measured the distance from the tip of the file to radiographic apex and recorded their results. The error in working length was calculated as the observed value minus the known working length for each tooth type. A mixed-effects, full-factorial analysis of variance (ANOVA) model was used to model the error in working length. Included in the ANOVA model were fixed effects for type of image, vertical angulation, and the interaction of angle and film type. Tooth type and examiner were included in the model as random effects assuming a compound symmetry covariance structure. The repeatability of each examiner, for each film type, was assessed by estimating the intra-class correlation coefficient (ICC). The ICC was determined when 12 randomly selected images and radiographs were reevaluated 10 days after initial measurements. The repeatability of each examiner for Schick CDR was good with ICCs ranging from 0.67 to 1.0. Repeatability for the conventional film was poor with ICCs varying from -0.29 to 0.55. We found the error in the working length was not significantly different between film types (p = 0.402). After adjusting for angle, we found that error in the working length from the digital image was only 0.02 mm greater (95-percent CI: -0.03, 0.06) than the conventional film. Furthermore, there was not a significant difference among the angles (p = 0.246) nor in the interaction of image type with angle (p = 0.149). Based on the results of our study, we conclude that there is not a statistically significant difference in determining working length between Schick CDR and Kodak Ektaspeed film when vertical angulation is modified.

Abstract:
The need for the identification and appropriate development of talent in organisations has led to a renewed interest in the accuracy of tools used in this context. The objectives of the study were to: (1) determine whether there is a significant difference in the growth in theoretical capability as predicted by Career Path Appreciation (CPA) 1 and CPA 2 among the sample population, (2) determine whether there is a significant difference in Mode as predicted by CPA 1 and CPA 2 among the sample population, and (3) formulate recommendations for Talent Management and Industrial and Organisational Psychology practices and future research. The CPA is a tool used for the selection and development of talent nationally and internationally. Limited recent test-retest research has been done regarding the utilisation of the CPA in this context. Scholars in the field of industrial psychology could therefore benefit from follow-up research regarding the validity and reliability of the CPA. The research design is an ex post facto correlational design using longitudinal data of a sample of convenience (N=527). Overall, the results indicated a significant correlation between CLC for CPA 1 and CPA 2 as well as between Mode for CPA 1 and CPA 2. The CPA as a measure of theoretical capability is consistently accurate between measures and can be used with confidence for the identification and development of talent within organisations.

Abstract:
The ultimate importance of rotor position and speed information in permanent magnet synchronous (PMS) machines control, and the industry interest to the rotor and speed sensorless systems as a cost-saving and practical alternative to the motor control with mechanical sensors are emphasized. Major position and speed estimation schemes are then presented in detail. These are the: back electromotive force (EMF)-based method; flux linkage method; hypothesis rotor position method; saliency-based method, including high frequency signal injection and inverter switching harmonics schemes; and finally, the observer-based method, including state observer and extended Kalman filter-based schemes. Each scheme was discussed by presenting the corresponding fundamental principles, followed by the appropriate motor model, estimation procedure, and the implementation. Demanding criteria such as accuracy, robustness, swiftness, and capability of working over the entire range of motor operation are discussed with each method.

Full text
Abstract:
‘I have in my heart of hearts a favourite child. And his name is DAVID COPPERFIELD,’ wrote Dickens of what is the most personal, certainly one of the most popular, of all his novels. Dickens wrote the book after the completion of a fragment of autobiography recalling his employment as a child in a London warehouse, and in the first-person narrative, a new departure for him, realized marvellously the workings of memory. The embodiment of his boyhood experience in the novel involved a ‘complicated interweaving of truth and fiction’, at its most subtle in the portrait of his father as Mr Micawber, one of Dickens’s greatest comic creations. Enjoying a humour that never becomes caricature, the reader shares David’s affection for the eccentric Betsey Trotwood and her protégé Mr Dick, and smiles with the narrator at the trials he endures in his love for the delightfully silly Dora. Settings, (East Anglia, the London of the 1820s), people, and events are unified by their relationship to the story of Steerforth’s treachery, which reaches its powerful climax in the storm scene. This edition, which has the accurate Clarendon text, includes Dickens’s trial titles and working notes, and eight of the original illustrations by ‘Phiz’.

Abstract:
This chapter considers how the Home for Colored Children (HCC) recorded a version of its founding story that traces the genesis of the institution to a state law. Several succeeding versions of this tale cite the role of legislation in prompting the formation of a new institution for African Americans, suggesting that the state acted as a progressive agent, forcing changes in the handling of all dependent children. While this version of HCC's founding story is not entirely accurate, it contains an essential truth: progressive reform ideas were starting to circulate in this period and had real impact on the development of child care institutions. The story locates the impetus for change outside of the orphanage founders themselves, placing it instead on progressives working through the government to enact new state laws regulating child welfare.

Abstract:
Studies of mathematics learning disabilities (MLD) in persons with a known genetic syndrome can illustrate the heterogeneity of MLD by revealing distinct cognitive profiles linked to poor mathematics achievement. These profiles may model the development of MLD and have implications for diagnosis and intervention. This approach is evident in research on fragile X or Turner syndromes. Both syndromes have a high incidence of MLD, and their phenotypes include remarkable strengths and difficulties in select math skills. Girls with fragile X syndrome show remarkable rote knowledge that does not appear to support problem solving or conceptual mastery; at some stages, it may mask MLD. Girls with Turner syndrome have remarkably difficulty with math fluency and estimation, but untimed performance is often accurate, even under high working memory demands, suggesting unique compensatory strategies. These phenotypes have important implications for the roles of individual and developmental differences in MLD.

Abstract:
AbstractThis paper presents and investigates a cyber-physical fabrication workflow, which can respond to the deviations between built- and designed form in real-time with vision augmentation. We apply this method for large scale structures built from natural bamboo poles. Raw bamboo poles obtain evolutionarily optimized fibrous layouts ideally suitable for lightweight and sustainable building construction. Nevertheless, their intrinsically imprecise geometries pose a challenge for reliable, automated construction processes. Despite recent digital advancements, building with bamboo poles is still a labor-intensive task and restricted to building typologies where accuracy is of minor importance. The integration of structural bamboo poles with other building layers is often limited by tolerance issues at the interfaces, especially for large scale structures where deviations accumulate incrementally. To address these challenges, an adaptive fabrication process is developed, in which existing deviations can be compensated by changing the geometry of subsequent joints to iteratively correct the pose of further elements. A vision-based sensing system is employed to three-dimensionally scan the bamboo elements before and during construction. Computer vision algorithms are used to process and interpret the sensory data. The updated conditions are streamed to the computational model which computes tailor-made bending stiff joint geometries that can then be directly fabricated on-the-fly. In this paper, we contextualize our research and investigate the performance domains of the proposed workflow through initial fabrication tests. Several application scenarios are further proposed for full scale vision-augmented bamboo construction systems.

Abstract:
AbstractDeveloping systems that foster situation awareness in operators requires that stakeholders can make informed decisions about the design. These decisions must account for the operator’s underlying cognitive processes based on perception, comprehension, and projection of the system state. This chapter reviews the core cognitive processes responsible for monitoring and responding to changes in system state. Operators must perceive information before they can act in response, and the interface design affects operator accuracy and speed via known mechanisms (i.e., effects of color on visual search time). Perception of key information also relies on how the operator thinks during tasks, and certain design choices can support better attention control and detection of signals. After perceiving the information, operators also must comprehend and interpret the information. Design guidance and factors related to supporting comprehension are presented alongside explanations of how cognitive load and working memory affect the operator’s ability to develop and maintain a useful mental model of the system. This review of cognitive mechanisms gives designers a strong foundation to make informed decisions ranging from choosing an alarm color to assessing how much information should be on screen at once.

Abstract:
The study is focused on the development, adaption and evaluation of the higher order Haar wavelet method (HOHWM) for solving differential equations. Accuracy and computational complexity are two measurable key characteristics of any numerical method. The HOHWM introduced recently by authors as an improvement of the widely used Haar wavelet method (HWM) has shown excellent accuracy and convergence results in the case of all model problems studied. The practical value of the proposed HOHWM approach is that it allows reduction of the computational cost by several magnitudes as compared to HWM, depending on the mesh and the method parameter values used.

Abstract:
Washington, DC is ranked second among cities in terms of highest public transit commuters in the United States, with approximately 9% of the working population using the Washington Metropolitan Area Transit Authority (WMATA) Metrobuses to commute. Deducing accurate travel times of these metrobuses is an important task for transit authorities to provide reliable service to its patrons. This study, using Artificial Neural Networks (ANN), developed prediction models for transit buses to assist decision-makers to improve service quality and patronage. For this study, we used six months of Automatic Vehicle Location (AVL) and Automatic Passenger Counting (APC) data for six Washington Metropolitan Area Transit Authority (WMATA) bus routes operating in Washington, DC. We developed regression models and Artificial Neural Network (ANN) models for predicting travel times of buses for different peak periods (AM, Mid-Day and PM). Our analysis included variables such as number of served bus stops, length of route between bus stops, average number of passengers in the bus, average dwell time of buses, and number of intersections between bus stops. We obtained ANN models for travel times by using approximation technique incorporating two separate algorithms: Quasi-Newton and Levenberg-Marquardt. The training strategy for neural network models involved feed forward and errorback processes that minimized the generated errors. We also evaluated the models with a Comparison of the Normalized Squared Errors (NSE). From the results, we observed that the travel times of buses and the dwell times at bus stops generally increased over time of the day. We gathered travel time equations for buses for the AM, Mid-Day and PM Peaks. The lowest NSE for the AM, Mid-Day and PM Peak periods corresponded to training processes using Quasi-Newton algorithm, which had 3, 2 and 5 perceptron layers, respectively. These prediction models could be adapted by transit agencies to provide the patrons with accurate travel time information at bus stops or online.

Full text
Abstract:
Many factors affect pavement compaction quality, which can vary. Such variability may result in an additional number of passes required, extended working hours, higher energy consumption, and negative environmental impacts. The use of Intelligent Compaction (IC) technology during construction can improve the quality and longevity of pavement structures while reducing risk for contractors and project owners alike. This study develops guidelines for the implementation of IC in the compaction of pavement layers as well as performing a preliminary life-cycle cost analysis (LCCA) of IC technology compared to the conventional compaction approach. The environmental impacts of the improved construction process were quantified based on limited data available from the case studies. The LCCA performed in this study consisted of different scenarios in which the number of operating hours was evaluated to estimate the cost efficiency of the intelligent compaction technique during construction. The analyses showed a reduction in energy consumption and the production of greenhouse gas (GHG) emissions with the use of intelligent compaction. The LCCA showed that the use of IC technology may reduce the construction and maintenance costs in addition to enhancing the quality control and quality assurance (QC/QA) process. However, a more comprehensive analysis is required to fully quantify the benefits and establish more accurate performance indicators. A draft version of the preliminary guidelines for implementation of IC technology and long-term monitoring of the performance of pavement layers compacted thereby is also included in this report.

Phillips, Jake. Understanding the impact of inspection on probation. Sheffield Hallam University, 2021. http://dx.doi.org/10.7190/shu.hkcij.05.2021.

Full text
Abstract:
This research sought to understand the impact of probation inspection on probation policy, practice and practitioners. This important but neglected area of study has significant ramifications because the Her Majesty’s Inspectorate of Probation has considerable power to influence policy through its inspection regime and research activities. The study utilised a mixed methodological approach comprising observations of inspections and interviews with people who work in probation, the Inspectorate and external stakeholders. In total, 77 people were interviewed or took part in focus groups. Probation practitioners, managers and leaders were interviewed in the weeks after an inspection to find out how they experienced the process of inspection. Staff at HMI Probation were interviewed to understand what inspection is for and how it works. External stakeholders representing people from the voluntary sector, politics and other non-departmental bodies were interviewed to find out how they used the work of inspection in their own roles. Finally, leaders within the National Probation Service and Her Majesty’s Prisons and Probation Service were interviewed to see how inspection impacts on policy more broadly. The data were analysed thematically with five key themes being identified. Overall, participants were positive about the way inspection is carried out in the field of probation. The main findings are: 1. Inspection places a burden on practitioners and organisations. Practitioners talked about the anxiety that a looming inspection created and how management teams created additional pressures which were hard to cope with on top of already high workloads. Staff responsible for managing the inspection and with leadership positions talked about the amount of time the process of inspection took up. Importantly, inspection was seen to take people away from their day jobs and meant other priorities were side-lined, even if temporarily. However, the case interviews that practitioners take part in were seen as incredibly valuable exercises which gave staff the opportunity to reflect on their practice and receive positive feedback and validation for their work. 2. Providers said that the findings and conclusions from inspections were often accurate and, to some extent, unsurprising. However, they sometimes find it difficult to implement recommendations due to reports failing to take context into account. Negative reports have a serious impact on staff morale, especially for CRCs and there was concern about the impact of negative findings on a provider’s reputation. 3. External stakeholders value the work of the Inspectorate. The Inspectorate is seen to generate highly valid and meaningful data which stakeholders can use in their own roles. This can include pushing for policy reform or holding government to account from different perspectives. In particular, thematic inspections were seen to be useful here. 4. The regulatory landscape in probation is complex with an array of actors working to hold providers to account. When compared to other forms of regulation such as audit or contract management the Inspectorate was perceived positively due to its methodological approach as well as the way it reflects the values of probation itself. 5. Overall, the inspectorate appears to garner considerable legitimacy from those it inspects. This should, in theory, support the way it can impact on policy and practice. There are some areas for development here though such as more engagement with service users. While recognising that the Inspectorate has made a concerted effort to do this in the last two years participants all felt that more needs to be done to increase that trust between the inspectorate and service users. Overall, the Inspectorate was seen to be independent and 3 impartial although this belief was less prevalent amongst people in CRCs who argued that the Inspectorate has been biased towards supporting its own arguments around reversing the now failed policy of Transforming Rehabilitation. There was some debate amongst participants about how the Inspectorate could, or should, enforce compliance with its recommendations although most people were happy with the primarily relational way of encouraging compliance with sanctions for non-compliance being considered relatively unnecessary. To conclude, the work of the Inspectorate has a significant impact on probation policy, practice and practitioners. The majority of participants were positive about the process of inspection and the Inspectorate more broadly, notwithstanding some of the issues raised in the findings. There are some developments which the Inspectorate could consider to reduce the burden inspection places on providers and practitioners and enhance its impact such as amending the frequency of inspection, improving the feedback given to practitioners and providing more localised feedback, and working to reduce or limit perceptions of bias amongst people in CRCs. The Inspectorate could also do more to capture the impact it has on providers and practitioners – both positive and negative - through existing procedures that are in place such as post-case interview surveys and tracking the implementation of recommendations.

Tuko Pamoja: A guide for talking with young people about their reproductive health. Population Council, 2005. http://dx.doi.org/10.31899/rh16.1017.

Full text
Abstract:
This guide was developed for public health technicians working with the Ministry of Health as part of the Kenya Adolescent Reproductive Health Project Tuko Pamoja (We Are Together). It can be used by anyone wishing to broaden their understanding of adolescent reproductive health (RH) issues and improve communication with young people. Providing young people with support by talking with and listening to them as well as ensuring they have access to accurate information can help them understand the wide range of changes they are experiencing during adolescence. Although parents, teachers, religious and community leaders, and health-care providers are expected to educate adolescents about personal and physical development, relationships, and their roles in society, it may be difficult for them to do so in a comfortable and unbiased way. For these reasons, it is important to meet adolescents’ need for information and services. Adolescent RH education provides information about reproductive physiology and puberty; protective behavior; and the responsibilities and consequences that come with sexual activity. Providing young people with accurate RH information promotes sexual health and well-being, and supports healthy, responsible, and positive life experiences, as well as preventing disease and unintended pregnancy.
