Deep Learning vs. Atlas-Based Models for Fast Auto-Segmentation of the Masticatory Muscles on Head and Neck CT Images
No full textBACKGROUND: Impaired function of masticatory muscles will lead to trismus. Routine delineation of these muscles during planning may improve dose tracking and facilitate dose reduction resulting in decreased radiation-related trismus. This study aimed to compare a deep learning model with a commercial atlas-based model for fast auto-segmentation of the masticatory muscles on head and neck computed tomography (CT) images.
MATERIAL AND METHODS: Paired masseter (M), temporalis (T), medial and lateral pterygoid (MP, LP) muscles were manually segmented on 56 CT images. CT images were randomly divided into training (n = 27) and validation (n = 29) cohorts. Two methods were used for automatic delineation of masticatory muscles (MMs): Deep learning auto-segmentation (DLAS) and atlas-based auto-segmentation (ABAS). The automatic algorithms were evaluated using Dice similarity coefficient (DSC), recall, precision, Hausdorff distance (HD), HD95, and mean surface distance (MSD). A consolidated score was calculated by normalizing the metrics against interobserver variability and averaging over all patients. Differences in dose (∆Dose) to MMs for DLAS and ABAS segmentations were assessed. A paired t-test was used to compare the geometric and dosimetric difference between DLAS and ABAS methods.
RESULTS: DLAS outperformed ABAS in delineating all MMs (p \u3c 0.05). The DLAS mean DSC for M, T, MP, and LP ranged from 0.83 ± 0.03 to 0.89 ± 0.02, the ABAS mean DSC ranged from 0.79 ± 0.05 to 0.85 ± 0.04. The mean value for recall, HD, HD95, MSD also improved with DLAS for auto-segmentation. Interobserver variation revealed the highest variability in DSC and MSD for both T and MP, and the highest scores were achieved for T by both automatic algorithms. With few exceptions, the mean ∆D98%, ∆D95%, ∆D50%, and ∆D2% for all structures were below 10% for DLAS and ABAS and had no detectable statistical difference (P \u3e 0.05). DLAS based contours had dose endpoints more closely matched with that of the manually segmented when compared with ABAS.
CONCLUSIONS: DLAS auto-segmentation of masticatory muscles for the head and neck radiotherapy had improved segmentation accuracy compared with ABAS with no qualitative difference in dosimetric endpoints compared to manually segmented contours
Economic utopia of the Torah. Economic concepts of the Hebrew Bible interpreted according to the Rabbinical Literature
No full textHebrew Bible offers alternative Economic utopia for building Theocratic society. In this paper, various economic concepts and themes are presented, as found in the Hebrew Bible. These economic concepts include taxation, property rights, labor market, social policy, banking, years of Sabbath and Jubilee, and business cycles. Most economic issues of the Bible are found in the texts of Torah, also known as five Books of Moses. These texts are analyzed by using classical Rabbinical commentaries for better insight. Contrary to the modern Economic theory which is based on the assumptions of scarcity of resources and unlimited needs of consumers, Economics of the Torah is based on God’s resources which are enough for all true needs of His people.Hebrew Bible, History of Economics, History of Economic Thought, Ancient Israel, Judaism
A CONCURRENT VALIDITY STUDY OF THE MISSOURI ADAPTIVE ABILITY SCALE AND THE ADAPTIVE BEHAVIOR ASSESSMENT SYSTEM, THIRD EDITION—TEACHER FORM
No full textThis study utilizes correlational data to demonstrate the construct validity of the Missouri Adaptive Ability Scale (MAAS) by comparing it to Adaptive Behavior Assessment System, Third Edition (ABAS-3) Teacher Form, a thoroughly researched and validated measure of independent living and adaptive functioning. The purpose was designed to extend research conducted to achieve construct validity of the MAAS. Twenty-six high school students with low incidence handicapping conditions (M = 17 years old) were included in this study. The ABAS-3 Teacher Form was obtained from archives and the MAAS was administered directly to the participants by the author. Pearson correlations revealed strong correlations across most MAAS/ABAS-3 combinations, supporting the concurrent validity of the MAAS. Implications, limitations, and suggestions for future research are discussed
Remote river rating in Zambia: A case study in the Luangwa river basin
No full textDirect measurement of river discharge is difficult, time consuming and costly. Therefore a rating curve is often used to estimate the river discharge. Limited measurements under extreme conditions result in extrapolation of the rating curve for high flow conditions. This induces uncertainties and errors in the stage-discharge relation. Recently there has been a gradual shift to more physically based rating curves, where the geometry of a river is included and no extrapolation is needed. This seems to be a promising shift to improve traditional river rating. However, the challenge now is to accurately determine the parameters bed roughness and hydraulic slope. The aim of this research is to develop and evaluate a method to better estimate the hydraulic parameters bed roughness and hydraulic slope. To do so a case study has been carried out in the Luangwa river catchment in Zambia
Understanding factors that influence the daily living skills of adults with autism
No full textExisting literature has demonstrated that the adaptive functioning of autistic individuals is lower than what is expected of their age and cognitive abilities. Studies of children and adolescents suggest that autistic individuals may show a relative strength in the adaptive domain of daily living skills (DLS). DLS skills refer to a broad range of activities that are necessary in helping one maintain their day-to-day personal lives and wellbeing. To date, few studies have examined these skills in autistic adults. This dissertation aimed to understand individual characteristics (i.e., intellectual function, executive function and mental health) and contextual factors (i.e., provision of opportunities, requirement of reminders) that influence autistic individuals’ performance of DLS. Participants included 33 autistic individuals ranging in age from 16 to 35 years. Results demonstrated associations between the Vineland Adaptive Behavior Scales, 3rd edition – Comprehensive Interview Form (VABS-3) DLS scores and intellectual and executive functioning, but not age and mental health. Qualitative analysis of parental responses indicated that not having an opportunity to learn and/or practice the assessed tasks was the most frequent reason for not performing DLS, particularly for adults with average or higher IQ. VABS-3 DLS scores tended to be lower than caregiver reported DLS scores on the Adaptive Behavior Assessment System, 3rd edition – Adult Form (ABAS-3), another measure of adaptive skills. While there were significant discrepancies between IQ and DLS measured by both VABS-3 and ABAS-3, the pattern varied by instruments, with the mean VABS-3 DLS standard score being approximately one standard deviation (SD) lower than the mean ABAS-3 DLS score. Even when accounting for the differences in floors between measures, the VABS-3 DLS remained lower than ABAS-3 DLS. These findings highlight a need for multi-dimensional assessment to characterize each individual’s patterns of strengths and difficulties, especially to understand contextual factors affecting daily living performance, to more readily inform the development of individualized intervention plans.Psy.D.Includes bibliographical reference

No full textSalt intrusion in the Pungue estuary, Mozambique: A case study on modelling the salinity distribution in the Pungue estuary
No full textAdditional thesis - The Pungue river originates in Zimbabwe and drains into the Indian Ocean creating a large alluvial estuary. The river discharge generated in the Eastern Highlands of Zimbabwe is an important source of fresh water for water consumers in Mozambique. In Mozambique the fresh water is used for drinking water production for the city of Beira and for irrigation and process purposes of the sugarcane estate of Mafambisse. The Mafambisse sugarcane estate strongly depends on the fresh water supply of the Pungue river. In the dry season when a low discharge is combined with a high tidal range salt intrusion can lead to high salinity values at the water intake of the estate. If the salinity exceeds the threshold of 0.16 kg/m3 the water cannot be taken in, without seriously affecting the yield or the operation of the sugarcane factory. The objective of this research is to obtain a thorough insight in the characteristics of the salt intrusion in the Pungue estuary in order to give preliminary solutions to the sugarcane estate. To get insight in the characteristics of salt intrusion data is collected during November and December of 2016. In order to describe the parameters in the steady and unsteady state salt intrusion models the estuary geometry is determined, the river discharge has been measured and salinity measurements have been conducted. The steady state salt intrusion model is calibrated on salinity measurements carried out with the moving-boat method. The salinity measurements show a sudden increase in salinity values around 60 kilometres from the estuary mouth. From the calibration it becomes clear that the steady state model is not able to represent these irregularities in the salinity distribution. This research shows that it is likely that an additional source of salt is causing the increase in salinity values and that the unsteady state salt intrusion is able to represent this. To see the effect of extreme situations of the tide and river discharge on the salinity distribution in the Pungue estuary four scenarios have been developed and compared with a reference scenario. The following scenarios are chosen: expansion of FIPAG (drinking water company), an increased extraction rate of Mafambisse, a drought and a bend cutoff. From the scenarios it can be concluded that with exception of the expansion of FIPAG all scenarios exceed the salinity threshold at the intake causing serious water shortages. The most extreme situation is reached in case of a drought. The salinity value modelled at the intake becomes 2.63 kg/m3 and the salt intrudes up to 84.5 km. In this situation no extractions are possible and Mafambisse will suffer from severe water shortages. To provide the sugarcane estate with preliminary solutions in preventing salinity incidents at the intake this research elaborates on three concrete recommendations. A straightforward solution to reduce salt incidents at the intake would be the relocation of the pumping station. This research suggests relocating the pumping station to 90 km or further from the estuary mouth. Another solution offered would be an alternated pumping scheme. This research shows that alternated pumping can be beneficial under certain conditions; a high salt intrusion length combined with a relatively high extraction rate. Under these conditions an alternated pumping scheme can lead to a larger extraction volume compared to the situation where the pumps are in constant operation and suddenly needs to be turned off. This is the case because the advective transport of salt by the river is much faster than the process of effective dispersion. The last recommendation is to monitor the additional salt sources, which causes irregularities in salinity distribution. Once these sources are located it is possible to control the flushing of saline water into the river by making use of small structures (e.g. sluices).Civil Engineering and GeosciencesWater Managemen
