Development of a reliable path-loss model for FM broadcast reception in office locations

This paper proposes for the development of a path-loss model to improve the accuracy in predicting the signal level in office locations for the reception of FM broadcast. Identifying the factors that affect the signal level and eventually developing a model to predict the signal inside buildings will guide engineers in designing a broadcast system. A properly designed broadcast system will ensure optimum signal penetration in these listening areas. Further, the developed model can find applications in policy-making on the regulation of FM broadcast stations, both for analog and digital radio systems. Signal level measurements from three FM broadcast stations have been made inside eight office rooms in De La Salle University-Manila. With the three stations utilizing circularly polarized transmitting antennas, the measurements aim to determine the signal levels of the horizontal and vertical components of the received signal. These measured levels are used to determine the effects on the magnitude of the received signal of some factors, such as signal frequency and polarization, receiving antenna height, walls, transmitter-receiver distance, etc. Since the developed model is based on the measured signal levels in the actual office environment, its accuracy is then better than any of the existing models earlier developed.
High-Precision Rotor Position Correction Strategy for High-Speed Permanent Magnet Synchronous Motor Based on Resolver

A high-precision rotor position correction strategy for a 2.5 kW@10 000 r/min permanent magnet synchronous motor (PMSM) based on the resolver is proposed in this article. The resolver as the rotor position sensor for PMSM has the advantage of long service life and high anti-interference. However, it is common that the unbalance amplitude of the resolver signal and the nonideal resolver-to-digital converter cause the rotor position estimation error. To solve these problems, a self-adaption rotor position correction strategy is proposed. First, the relationship between the q-axis current and the rotor position estimation error is analyzed. The error from estimate and the imbalances of the resolver-to-digital converter circuit are decoupled. Then, a rotor position correction strategy based on self-adaption controller is presented, and the self-adaption controller can compensate the estimation error both from unbalance amplitude of the resolver signal and the nonideal resolver-to-digital converter. Finally, the effectiveness and feasibility of the correction strategy are verified by the experiments on a 2.5 kW@10 000 r/min PMSM platform.
Exploring the universal design principles of a Flipped Classroom model for Inquiry-Based Learning in Cyprus primary education context : a multiple case study

Background In this thesis, a multi-case study will be presented to address an important gap in current literature concerning universal design principles (UDPs) for an effective implementation of a Flipped Classroom (FC) model for Inquiry-Based Learning (IBL), called the IB-FC model. Currently, there has been limited research focusing on the implementation of any FC model within the primary education context despite its potential benefits, such as developing higher order cognitive skills. Method used The study is a collaborative research project, during which the research, in collaboration with five primary school teacher participants, explored the effective ways of universal implementation of the initial IB-FC model developed, in five different primary schools in Cyprus. The model was implemented for a school year (2017-18), involving 5 teachers, 77 students and 48 of their parents. Qualitative data has been selected mainly through classroom observations and interviews. Key results Data analysis has focused on teachers’, students’ and parents’ experiences and perceptions on the IB-FC implementation which aimed to revise the initial instructional tools, lesson template and framework given to the teachers for designing their lessons. This in turn led to the extraction of seven UDPs: structure and flexibility, simplicity and accessibility, interconnectivity and community, differentiation and personalization, development and progression, motivation and engagement and assessment and evaluation. Conclusion The final IB-FC framework proposed in the findings illustrates how the seven UDPs for IB-FC implementation are connected to the ten instructional IB-FC tools developed for further supporting IB-FC implementation. In summary, this study has clearly demonstrated that the FC methodology can be effectively implemented in primary education settings. The final IB-FC framework contributes to the slow growing body of research on FC and IBL practice, theory building and policy in primary education.
Obstetric outcome in patients with rheumatic heart disease: experience of a tertiary hospital.

Background and Aims: Pregnancy in patients with rheumatic heart disease has always been challenging. Haemodynamic changes in pregnancy with diseased heart may cause adverse maternal and fetal outcome.Methods: A prospective study was done in pregnant women with rheumatic heart disease over a period of 2 years from 2015 to 2016 at Tribhuwan University Teaching Hospital, Kathmandu. Baseline data collected at antenatal period were analyzed with obstetric outcomes.Results: A total of 85 women were enrolled in this study. Sixty percent of the women were primigravida. Mitral stenosis was the commonest lesion (69.41%), followed by mitral regurgitation (25.88%) and aortic stenosis (4.71%). Cardiac events were noted in 32 patients out of which 11 developed pulmonary oedema and 6 had new onset of atrial fibrillation. Vaginal delivery (58.82%) was the commonest mode of delivery followed by cesarean section (24.7%). Eighty percent of women remained in NYHA functional class I and II, whereas 20% had deterioration of functional class. There were more maternal and fetal complications in women with NYHA III or IV in comparison to women with NYHA I or II. Low birth weight infants were found in 37.64% of cases. There was one maternal death in a lady with severe mitral stenosis with moderate mitral regurgitation due to congestive heart failure at 34 weeks of gestation. There were 8 fetal and 11 neonatal deathConclusions: Functional cardiac status during pregnancy has a major impact on maternal and fetal outcome. Rheumatic heart disease diagnosed before pregnancy may improve the outcome.Nepalese Heart Journal 2017; 14(2): 31-34
Learning Joint Job Embeddings Using a Job-Oriented Asymmetrical Pairing System

A main objective of Human Resources (HR) professionals is to suggest relevant job opportunities to people seeking change. This requires they identify key features in thousands of badly entitled, loosely-deﬁned and often long job descriptions to compare job offers. However, an ever-increasing number of proﬁles and many similar-looking job opportunities combined with a quickly evolving job market make this task signiﬁcantly harder and require advanced automatic tools. In this work, we tackle these problems by building a job embedding space called job2vec and a title predictor from a description. To do so, we propose the ﬁrst Job-Oriented Asymmetrical Pairing System, JOAPS which on one hand uses a title encoder to create the job2vec and on the other hand uses a description encoder to predict a job title from a job description. The JOAPS architecture is based on two different sub-neural networks connected at their outputs us-ing a novel weighted ranking pairwise loss, that we named Weighted On-the-ﬂy Chunk Ranking (WOCR) loss, to back-propagate simultaneously to both sub-networks. First, we compare the job2vec built by JOAPS to a word2vec-based job2vec . Then we compare the JOAPS description encoder to a Sequence to Sequence baseline model. Our experiments show that JOAPS job2vec incorpore HR key features, whereas word2vec-based job2vec only combines features extracted from job title words. Thus JOAPS job2vec has more suitable properties to compare jobs, even with never-seen-before job titles. Futhermore, we show that JOAPS description encoder outperforms the Seq2Seq baseline method in title prediction.
Original Contribution Alcohol consumption is directly associated with circulating oxidized low-density lipoprotein

Findings on the association of alcohol consumption and oxidation of low-density lipoprotein (LDL), which is thought to play a crucial role in the generation of atherosclerotic lesion, are inconsistent. The aim of the present study was to investigate the association of total alcohol consumption and type of alcoholic beverage with circulating plasma LDL oxidation. This cross-sectional study included data of circulating oxidized LDL (ox-LDL) from a subpopulation of 587 men and women enrolled in a population-based survey conducted in 2000 in Girona (Spain). Multivariate analysis was performed to describe the independent association of alcohol consumption and ox-LDL. Increasing alcohol consumption was associated with high in vivo ox-LDL levels in the present population. The consumption of 10 g of alcohol was associated with an increase of 2.40 U/L of ox-LDL (p = 0.002). Adjustment for dietary variables, leisure-time physical activity, educational level, smoking, LDL-cholesterol, high-density lipoprotein-cholesterol, glycemia, triglycerides, diabetes, body mass index, waist circumference, and systolic and diastolic blood pressures only slightly modified this association (p = 0.003). In this full adjusted model the consumption of 10 g of alcohol per day was associated with an increase of 2.11 U/L of ox-LDL. Consumption of wine (ml/day) was associated with increasing ox-LDL levels (p = 0.029), however, attenuated after controlling for alcohol. No significant relationship of ox-LDL with alcohol-independent consumption of wine, beer, and spirits was observed. Alcohol consumption was independently and directly associated with circulating ox-LDL in the present population.
Adoptive Parenting Cognitions: Acknowledgement of Differences as a Predictor of Adolescents’ Attachment to Parents

SYNOPSIS Objective. Adoptive parents’ acknowledgment of differences is defined as the propensity to think that adoptive and nonadoptive families are different in important ways. Few studies have examined the implications of such cognitions for the parent–child bond. Design. Structural equation modeling was utilized to examine the relation between adoptive parents’ acknowledgment of differences and adolescents’ later attachment to their parents in a sample of within-race domestic infant adoptions. Data from 189 adoptive families were drawn from two waves (middle childhood, adolescence) of the Minnesota/Texas Adoption Research Project, a longitudinal study of openness in adoption. Results. Levels of acknowledgment of differences displayed by the adoptive mother and adoptive father during middle childhood positively predicted adopted adolescents’ feelings of attachment toward the respective parent 8 years later. This relation depended on adopted adolescents’ attitude toward adoption-related communication during middle childhood as well as the adoptive family’s level of openness during middle childhood. Conclusions. Acknowledgment of differences in adoptive families has positive implications for the parent–child bond.
Informal STEM: learning with robotics and game design in an urban context

Abstract This mixed methods study examined how engagement in robotics and game design influenced students’ self-efficacy, STEM attitudes, and computational thinking (CT) skills. Predominantly African-American students engaged in engineering and computer science tasks during informal learning environments. Results revealed students’ self-efficacy scores on computer gaming increased significantly. Focus group data supported these findings, revealing that computer programing was challenging, but students enjoyed the tasks, added elements of culture in some cases, and valued the agency the tasks provided. Focal students were also able to make connections to STEM-related careers. Observational data demonstrated that focal students exhibited substantive CT during robotics and moderate CT during game design. Results support the idea that robotics and game design may be used to broaden underrepresented students’ participation in STEM.
ASSOCIATION OF LIPID PROFILES WITH 10-YEAR ATHEROSCLEROTIC CARDIOVASCULAR DISEASE RISK: STUDY AMONG SUBJECTS IN SLEMAN DISTRICT OF YOGYAKARTA INDONESIA

Objectives: The subjects in the Sleman District of Yogyakarta had medium Framingham risk score (FRS) in the preceding year study. The 10-year atherosclerotic cardiovascular disease (ASCVD) risk was a newer risk estimator than FRS. This study aimed to associate the lipid profiles with the ASCVD risk. Methods: The study was conducted with a cross-sectional design and the subjects were selected with cluster random sampling. The association of lipid profiles and ASCVD risk was analyzed with Mann–Whitney/Kruskal–Wallis tests and Spearman’s rho correlation, whereas the categorical scores within sub-groups were analyzed Chi-square statistics, respectively. Results: The eligible subjects (n=221) had the age at 51.7±8.1 years, systolic/diastolic blood pressure 136.8±22.4/85.0±12.4 mmHg, total-cholesterol (total-C), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), and triglyceride at 202.0±34.9 mg/dl, 52.6±12.5 mg/dl, 126.3±30.0 mg/dl, and 135.9±95.4 mg/dl, respectively; with hypertension treatment 16.7%, smoking 52.9%, diabetes 10.4%, and the median ASCVD risk at 4.4 (0.2-41.4). The ASCVD risk has significant association with non-lipid profiles, total-C, lipid ratio of triglyceride/HDL-C, total-C/HDL-C, and LDL-C/HDL-C, to a lesser extent, HDL-C, LDL-C, and triglyceride. Conclusion: The 10-year ASCVD risk of the subjects was categorized as low and had a significant association with total-C and lipid ratio of triglyceride/ HDL-C, total-C/HDL-C, and LDL-C/HDL-C.

Towards automated dynamic scene analysis and augmentation during image-guided radiological and surgical interventions

This thesis proposes non-invasive automated scene analysis and augmentation techniques to improve navigation in image-guided therapy (IGT) applications. IGT refers to procedures in which physicians rely on medical images to plan, perform, and monitor an intervention. In IGT, the tomographic images acquired before the intervention may not directly correspond to what the physician sees via the intraoperative imaging. This is due to many factors such as: time-varying changes in the patient’s anatomy (e.g., patient positioning or changes in pathology), risk of overexposure to ionizing radiation (restricted use of X-ray imaging), operational costs, and differences in imaging modalities. This inconsistency often results in a navigational problem that demands substantial additional effort from the physician to piece together a mental representation of complex correspondences between the preoperative images and the intraoperative scene. The first direction explored in this thesis, investigates the application of image-based motion analysis techniques for vessel segmentation. Specifically, we propose novel motion-based segmentation methods to enable safe, fast, and automatic localization of vascular structures from dynamic medical image sequences and demonstrated their efficacy in segmenting vasculature from surgical video and dynamic medical ultrasound sequences. The second direction investigates ways in which navigation uncertainties can be computed, propagated, and visualized in the context of IGT navigation systems that target deformable soft-tissues. Specifically, we present an uncertainty-encoded scene augmentation method for robot-assisted laparoscopic surgery, in which we propose visualization techniques for presenting probabilistic tumor margins. We further present a computationally efficient framework to estimate the uncertainty in deformable image registration and to subsequently propagate the effects of the computed uncertainties through to the visualizations, organ segmentations, and dosimetric evaluations performed in the context of fractionated image-guided brachytherapy. Our contributions constitute a step towards automated and real-time IGT navigation and may, in the near future, help to improve interventional outcomes for patients (improved targeting of pathologies) and increase surgical efficiency (less effort required by the physician).
Smartphone Apps Using Photoplethysmography for Heart Rate Monitoring: Meta-Analysis

Background Smartphone ownership is rising at a stunning rate. Moreover, smartphones prove to be suitable for use in health care due to their availability, portability, user-friendliness, relatively low price, wireless connectivity, far-reaching computing capabilities, and comprehensive memory. To measure vital signs, smartphones are often connected to a mobile sensor or a medical device. However, by using the white light-emitting diode as light source and the phone camera as photodetector, a smartphone could be used to perform photoplethysmography (PPG), enabling the assessment of vital signs. Objective The objective of this meta-analysis was to evaluate the available evidence on the use of smartphone apps to measure heart rate by performing PPG in comparison with a validated method. Methods PubMed and ISI Web of Knowledge were searched for relevant studies published between January 1, 2009 and December 7, 2016. The reference lists of included studies were hand-searched to find additional eligible studies. Critical Appraisal Skills Programme (CASP) Diagnostic Test Study checklist and some extra items were used for quality assessment. A fixed effects model of the mean difference and a random effects model of Pearson correlation coefficient were applied to pool the outcomes of the studies. Results In total, 14 studies were included. The pooled result showed no significant difference between heart rate measurements with a smartphone and a validated method (mean difference −0.32; 99% CI −1.24 to 0.60; P=.37). In adults, the Pearson correlation coefficient of the relation between heart rate measurement with a smartphone and a validated method was always ≥. 90. In children, the results varied depending on measuring point and heart rate. The pooled result showed a strong correlation that was significant (correlation coefficient .951; 95% CI 0.906-0.975; P<.001). The reported limits of agreement showed good agreement between a smartphone and a validated method. There was a moderately strong significant negative correlation between the year of publication of the included studies and the mean difference (r=−.69; P<.001). Conclusions Smartphone apps measuring heart rate by performing PPG appear to agree with a validated method in an adult population during resting sinus rhythm. In a pediatric population, the use of these apps is currently not validated.
Price Transmission and Signals of Cowpea Across Zones and Value Chain in Niger State of Nigeria

This study investigated price transmission and signals of the three major urban cowpea markets and their respective adjunct rural market across the zones and value chain in Niger state of Nigeria using monthly time series data spanning from January 2003 to December 2016. The selected urban markets were Bida, Minna, and Kontagora, and their adjunct markets were Lafene, Zungeru, and Manigi, respectively. Model build on the assumption of linear and symmetric price transmission was used to analyze the data. The stationarity tests showed that the price series of all the variables were integrated of order one. The cointegration test results of the markets both at horizontal and vertical integrated levels proved that despite that, these markets were spatially separated geographically; they were well connected in terms of price transmission across them. It was observed that price changes are temporary and would converge to equilibrium within a given time span. However, Bida market was found to me more pricing and operational efficiency when compared to its counterparts because of its close proximity to the largest terminal markets for cowpea in the country, i.e., Lagos state and other states in the southwest of Nigeria. Furthermore, the price signals across the zones and value chain will be well transmitted, indicating that price changes in one zone are consistently related to the price changes in other zones and are able to influence the prices in other zones. However, the direction and intensity of price changes may be affected by the dynamic linkages between the demand and supply of cowpea. A proper focus on domestic supply management along with international trade coupled with strong market surveillance and intelligence efforts would help control escalating prices and also help in minimizing the distortions widening the gap between the wholesale and retail prices of cowpea.
Persistent Cutaneous Infection Due to Mycobacterium Immunogenum, a Relatively Novel Species

Mycobacterium immunogenum is a species of nontuberculous mycobacteria (NTM) that has been recently identified as the cause of cutaneous infections. 1-3 Historically, the majority of NTM infections were attributed to contamination of municipal water systems due to inadequate equipment sterilization. Many of these organisms have been found to grow in distilled water and display resistance to chlorine, formaldehyde, mercury, and standard disinfectants. 4 In the environment, M. immunogenum has been isolated in swimming pools and adjacent showers. 5 A limited number of cutaneous infections with Mycobacterium immunogenum have been reported, and an even smaller number of cases have been reported in immunocompetent individuals. We report a case of a persistent cutaneous infection with M. immunogenum in a previously healthy patient successfully treated with clarithromycin 250 mg twice daily for eight weeks. After treatment, the patient remained free of infection and only a minimal scar remained.
