Forecast of Highway Subgrade Settlement Based on Improved BP Neural Network

Research Article of Scientific Research and Reviews Forecast of Highway Subgrade Settlement Based on Improved BP Neural Network Shengxiang Ma China Academy of Safety Science and Technology, Beijing, China In order to improve the feasibility and accuracy of the roadbed settlement prediction model, the factor analysis method is combined with the BP neural network method, and an improved BP neural network roadbed settlement prediction model is proposed. Select example data to test the improved BP neural network roadbed settlement prediction model. The test results: The relative average error of the 10 sets of training samples’ predicted and actual roadbed settlements was 4.287%, and the roads of five predicted samples The relative error of subgrade settlement is 1.79%, 1.93%, 6.62%, 7.19%, 4.05%, all less than 10%, which proves that the improved BP neural network prediction model has good prediction accuracy.

Build-Operate-Transfer Model and Its Role in Developing Railways Transport Section in Sudan

Review Article of American Journal of Transportation and Logistics Build-Operate-Transfer Model and Its Role in Developing Railways Transport Section in Sudan Omar Ismail Omar Mohammad Sudan University of Science and Technology. This paper focuses on a solution to the finance restrictions that obstacle the development of railways section in Sudan. Sudan is a big country with an area estimated at more than 1,800,000 km2. It owns variety of natural and other resources. The transportation system in Sudan specially railways suffers a lot of restrictions that affect its contribution to the national economy. Sudan railways is one of the longest railways in Africa with about 5,000 km. Railways were the earliest mechanical means of transport to be introduced in Sudan. The construction of the first railway line started in the last decade of the Nineteen century. Railways have been playing a significant role in transportation for long time. However, railways in Sudan lack passengers’ trains recently. Moreover, the capacity of freight trains is enough to meet just 10% of needed capacity. Also, most of the rails are very old and exceeded their expire date; and as the result a lot of derailments had been occurred. Also, most of the rail on the western lines are not suited to all of the diesels. Moreover, most sleepers are creosoted wood which differ from that used in the neighboring countries that use steel or concrete. And to overcome all these issues, there is a huge need of finance. However, lacking of finance is one of the main restrictions that face the development of railways section in Sudan. And, in spite of that, the Build Operate-Transport (BOT) approach could be the best option to deal with the current situation that faces railways section in Sudan. Build-Operate-Transport Approach (BOT) is a well-known method of initiating, financing ...

Image Restoration for University Leaders’ Public Health COVID-19 Response: A Case Study of Notre Dame

Research Article of International Research Journal of Public Health Image Restoration for University Leaders’ Public Health COVID-19 Response: A Case Study of Notre Dame R. Tyler Spradley, Ph.D. Department of Languages, Cultures, and Communication, Stephen F. Austin State University Do as I say, not as I do is a common phrase that applies to the case of Notre Dame’s president as he began the Fall 2020 semester chastising students for gathering in large groups off campus leading to the spread of COVID-19 while he, just a month later, gathered unmasked in the U.S. White House Rose Garden to celebrate the nomination of a Notre Dame alum to the Supreme Court.  This study draws upon image restoration strategies in crisis response literature to examine Notre Dame and its president’s public response to both the two-week move to remote education in Fall 2020 following COVID-19 outbreak among its students and the unmasked attendance to an event that resulted in Notre Dame’s president testing positive for COVID-19.  Overall, evasion of responsibility and corrective action typified the university’s response to students’ behaviors that led to public health risk, but mortification along with contradictory messages evading responsibility typified the individual response of the university’s president that led to public health risk.  Of interest to the case is the lack of religious appeal intertwined in the  image restoration strategies used in the president’s apology yet the use of religious appeal in the university’s accusations against student public health behavior.  Given that Notre Dame is a religiously affiliated university and the president is clergy, the inconsistent use of religious appeal may undermine the image restoration rhetoric of the president.

Non-Contact Respiratory Rate Monitoring with raybaby in an NICU: An Observational Study

Objectives: This study aimed at evaluating the reliability of respiratory rate obtained by a non-contact technology with respect to a medically validated monitor among preterm babies. Design: This observational study compared the respiratory rates from raybaby’s non-contact technology and FDA approved Earlysense unit for the same instants of time through 760 hours of monitoring. 18 preterm babies in the NICU of a paediatric specialty hospital in India were considered for the study. The raybaby device was installed in front of the incubator and the contact-free FDA approved device was placed below the mattress of the incubator. The Respiratory Rate monitored was displayed on the device’s monitoring screen. Respiratory rates from both devices were compared to calculate the agreement between the values. Correlation, Accuracy, Hit Percentage and Fit Curves for the non-contact technology of raybaby with respect to the clinically certified device. Results: With 760 hours of monitoring, 37404 breathing instances were analysed. This yielded an accuracy of 98%. 95% of the data points fell within the +/- 5 units error range which is usually followed by medical devices. Conclusions: Raybaby uses a ...

Transtheoretical model as a framework for promoting cardiovascular health through behaviour change: a systematic review

Review Article of International Research Journal of Public Health Transtheoretical model as a framework for promoting cardiovascular health through behaviour change: a systematic review PhD, Ejiofor A. Ezika1* , MBBS, Adaobi Nwankwo-Ezika2 1School of Health and Life Sciences, University of the West of Scotland. 2Emergency Medicine Department, Southend University Hospital. Introduction: Cardiovascular disease (CVD) remains the single leading cause of death around the globe. The Transtheoretical model (TTM) is a successful framework for guiding behaviour change programmes for several health behaviours, yet there are limited reviews on how TTM has been used to facilitate behaviour change associated with reduced CVD. Therefore, the aims of this systematic review are to determine (i) how TTM has been used in promoting physical activity, fruit and vegetable consumption, and smoking cessation and (ii) gaps in knowledge in the use of stage-based model to improve physical activity, intake of fruit and vegetables, and smoking cessation. Materials and Methods: The approach to this systematic review was informed by current recommendations known as Preferred Reporting Items for Systematic Reviews and Meta-analysis Approach (PRISMA). Results: Constructs of TTM were used in the design of studies, facilitation of health behaviour change, monitoring of change in the movement of the participants across the change continuum, and evaluation of the effectiveness of health behaviour programmes. TTM was incorporated with other models, including Health Belief Model (HBM), social-ecological model, and social cognitive theory to facilitate behaviour change. There were limited studies that used all the four constructs of TTM to promote health behaviour change. Conclusion: TTM is a promising tool for designing, facilitating, monitoring, and evaluating behaviour change associated with reduced cardiovascular disease (CVD). TTM may be incorporated with other models, including HBM, social-ecological model, and social cognitive theory to facilitate behaviour change.

Surgical difficulties with a giant carcinoid in the anterior mediastinum

Case Report of International Journal of Case Reports Surgical difficulties with a giant carcinoid in the anterior mediastinum Miklos Boros MD1*, Ulf Hermansson MD1, Ingemar Vanhanen PhD1 1Department of Cardiothoracic Surgery, University of Linköping, Linköping, Sweden. Atypical carcinoid in the anterior mediastinum is a rare neoplasm. In our case the huge mediastinal carcinoid was treated with surgery using a median sternotomy and clamshell incision because of the extension of the tumor. We describe our difficulties under the surgery and take a look at the literature.
