Published: June 2020

Abstract
Electro-Hydraulic Servo (EHS) system is a well-known nonlinear system in various types of industries due to its outstanding characteristics over other actuators. Despite its wide applications in industries, this system also suffering from nonlinearities and parameter uncertainties. Sliding Mode Controller (SMC) has been proven by many researchers to be effective in positioning control of the nonlinear system. However, SMC controller parameters must be tuned in appropriate ways to control the EHS system. In this research, an SMC strategy which combines with an enhanced PSO called Multi-Objective Particle Swarm Optimization (MOPSO) is proposed in positioning control of the EHS system. The conventional PSO is design as well for comparison purpose. The output performance is analysed and verified using different performance indexes such as rise time, settling time, overshoot percentage, and root mean square error. The results show that the MOPSO is better in tuning the controller parameters.

Published: June 2020

Abstract
This paper formulates a new mathematical algorithm for automated flame detection in high-speed image. The proposed algorithm is simple, unsupervised and computationally inexpensive to segment a sequence of such images into two levels which correspond to flame and background. Flame images are used as input to calculate and predict the threshold value of the image based on Otsu’s method. The threshold value of the current image is corrected to compute the flame boundary. The main idea is to exploit the images’ correlation in time to predict a suitable binarization threshold from the previous image. The algorithm is expected to compute the projected burnt area, which will be used to obtain the flame characteristics in a fast, robust, and reliable way. Then the proposed scheme was compared with two famous different methods and explore their effects on detection characters in scene images. It is found that the proposed method outperforms the other two prior methods in detection flame edges with respect to the flame radius versus time.

Abstract
WBS testing is the procedure of substantiation on material after a completed welding process to determine the material properties and behavior such as strength properties and forming properties. The conventional testing for determining strength properties of material involve parameters such as tensile strength, shear strength, toughness, brittleness and rigidity. On the other hand, the forming properties testing is performed to inspect elasticity, plasticity, ductility, malleability and hardness of the welded components. The importance of WPSs in the welding technology and how the WPSs is performed at the point around the welding procedure should be defined clearly. Thus, this project investigates the welding quality assessment in the industry by comparison of several testing methods (such as tensile and bend test) following determined acceptance criteria by American Welding Society (AWS D1.1). This research also aims to investigate the metallurgical aspects of welding joint by looking into different locations which as HAZ, weld metal and base metal. The investigated results are macro and microstructure observation, hardness distribution and also the density of the allocated area. This project will serve to develop a further understanding of welding and to find out the correlation between various testing methods that have been used. The welding quality assessment by comparison of mechanical testing properties and microstructure analysis are carried out to determine the property of the affected points. Then, the welding evaluation is determined by performing non-destructive and destructive testing methods. The comparison between the mechanical testing properties and microstructure analysis is made to determine welding quality of Shielded Metal Arc Welding. The acceptance criteria for both non-destructive and destructive testing were referred to American Welding Society (AWS) standard. Furthermore, this research is conducted to investigate the function of welding procedure specification in evaluation of welding quality assessment especially in oil and gas industry.

Driver’s mental workload is affecting the driver’s performance while driving. A high mental workload task proved that the driver’s performance level decrease. The decreasing of driver’s performance lead to driver carelessness that causes a road accident. Thus, the way to estimate and monitor the driver’s mental workload has to be developed. The purpose of this project is to monitor the driver’s mental workload and give a prompt warning to the drivers whether they are safe or not to drive, thus enhancing road safety. This project started by obtaining information about the driver’s mental workload through a driver’s heart rate. For early stage, this project conducted by using an electronic device for education, which is Arduino Kit and heart rate sensor. The heart rate sensor will detect the heart beat through the fingertips as an input. Then the input will be sent to Arduino, and it will monitor the reading of heart beat in beat per minutes (BPM) through a connected screen monitor. An experiment conducted in two conditions which are at rest condition and during Mathematical Arithmetic Task to estimate the driver’s mental workload. By using the developed sensor system, the threshold value of mental workload was collected. The buzzer will produce a sound if the reading heart rate value is exceeding the maximum threshold heart rate reading for the safe driving condition.

Abstract
Algae-silica hybrid (HA-S) from Porphyridium sp. has been modified by coating particles of magnetite (Fe3O4) via a sol-gel process using (TEOS) to produce silica-magnetite algae hybrid (HA-SM). The produced material HA-SM was applied as adsorbent for the multicomponent solution adsorption of Cu(II) ions, crystal violet (CV), and methylene blue (MB). Identification of functional groups was performed by infrared spectrometer (IR) indicating that in HA-SM there are an active organic groups derived from Porphyridium sp., while silanol and siloxane derived from silica matrix. In addition, the results of the analysis using Scanning Electron Microscopy with Energy Dispersive X-Ray (SEM-EDX) showed HA-SM has more heterogeneous surface morphology. The adsorption model of the multicomponent solutions of Cu(II) ions, CV, and MB by HA-S and HA-SM tend to follow the model of Freundlich adsorption isotherm.

Published: June 2020

Abstract
In this article, environmentally compatible, low cost and easy green synthesized pure and Al-doped ZnO nanoparticles from the Azadirachta indica leaves extract were prepared. The greenly produced nanoparticles were mainly studied for structural properties. The x-ray diffraction data show that these were crystalline with the hexagonal wurtzite phase. The average crystallite size and some other important physical parameters such as stress, strain and energy density were estimated from the Williamson Hall analysis with the help of Rietveld refinement data. It was observed that with increasing Al-concentration, the crystallite size decreased but the other parameters like stress, strain and energy density increased. It was also seen that with increasing Al addition from 0%–15% the inter-planar spacing d
hkl for each hkl set of the samples first decreased and then increased, which indicates the influence of the smaller size of Al ion addition on the inter-planar distance.

Authors: Chartier Christian , Chandawarkar Akash A , Gould Daniel J , Stevens W Grant 
Published: June 2020

Abstract

Background
Recent evidence shows accelerating worldwide adoption of social media and suggests a commensurate increase in social media use by integrated plastic surgery residency programs in the United States. Programs nationwide are now making strides to include a longitudinal social media component in their plastic surgery curriculum.

Objectives
The aim of this study was to investigate the use of Instagram by plastic surgery residency programs and to describe trends in adoption, volume, and content.

Methods
Current active Instagram accounts affiliated to integrated plastic surgery residency programs were surveyed to identify date of first post, number of posts, number of followers, number of followings, engagement rate, most-liked posts, and content of posts. All data were collected on May 12, 2020.

Results
Sixty-nine out of 81 (85.2%) integrated plastic surgery residency programs had Instagram accounts, totaling 5,544 posts. This represents an absolute increase in program accounts of 392% since 2018. The 100 most-liked posts were categorized as: promotion of the program/individual (46), resident life (32), promotion of plastic surgery (14), and education (8).

Conclusions
Instagram use by plastic surgery residency programs has drastically increased since it was first evaluated in 2018. This trend will continue as we reach near saturation of residency programs with accounts. We remain steadfast in our belief that the advantages of social media use by plastic surgeons and trainees are far outweighed by the potential community-wide impacts of violations of good social media practice on peers, patients, and the general public.

Published: June 2020

AbstractMedication overuse headache is estimated to affect 2% of the population, and is ranked in the top 20 most disabling disorders due to its high level of disability. Several therapies used in the treatment of acute migraine are thought to be associated with medication overuse headache, including opioids and triptans. With limited treatment options, it is critical to determine the risk profile of novel therapies prior to their widespread use. The current study explores the potential medication overuse risk of two novel therapeutic drug classes, namely the ditans: 5-HT1F receptor agonists, and the gepants: calcitonin gene-related peptide receptor antagonists, in a preclinical model of medication overuse. Persistent exposure of mice to the 5-HT1F agonist LY344864, but not olcegepant produced a significant reduction in hind paw and orofacial mechanical withdrawal thresholds as a surrogate readout of allodynia. In agreement, only LY344864 induced neuroplastic changes in trigeminal sensory afferents, increasing calcitonin gene-related peptide expression and basal trigeminal nociception. Our data highlight a differential medication overuse headache risk profile for the ditan and gepant classes of drugs that has important implications for their clinical use and patient education to help reduce the burden of medication overuse headache.

Published: June 2020

Abstract

Background
We sought to determine the rate of progression from dysplasia to adenocarcinoma in ulcerative colitis [UC] vs Crohn’s diseases [CD] and describe the risk factors unique to each.

Methods
All adult patients [≥18 years] with a known diagnosis of either UC or CD who underwent a surveillance colonoscopy between January 1, 2010 and January 1, 2020 were included.

Results
A total of 23 751 surveillance colonoscopies were performed among 12 289 patients between January 1, 2010 and January 1, 2020; 6909 [56.2%] had a diagnosis of CD and 5380 [43.8%] had a diagnosis of UC. There were a total of 668 patients [5.4%] with low-grade dysplasia [LGD], 76 patients [0.62%] with high-grade dysplasia [HGD], and 68 patients [0.55%] with adenocarcinoma in the series; the majority of the dysplastic events were located in the right colon. Significantly more UC patients had a dysplastic event, but the rate of LGD and HGD dysplasia progression to adenocarcinoma was not significantly different in CD or UC [p = 0.682 and p = 1.0, respectively]. There was no significant difference in the rate of progression from LGD/HGD to adenocarcinoma based on random biopsies vs targeted biopsies of visible lesions [p = 0.37]. However, the rate of progression from LGD vs HGD to adenocarcinoma was significantly greater for HGD [p &lt; 0.001].

Conclusion
While more UC patients were found to have neoplasia on colonoscopy, the rate of progression from LGD and HGD to adenocarcinoma was equivalent in UC and CD, suggesting that endoscopic surveillance strategies can remain consistent for all IBD patients.
