Design of Control System for Quadruped Robot (4-Legged Robot)

The project outcome is to design a control system for quadruped robot (4-legged robot). Early 2007, a quadruped robot was built by an UTP graduate; Mr. Tnay Chiat Siang (Matric No. 6114). The quadruped robot is well constructed in mechanicalwise; however, it has never been able to move as there is no motor driver and control system being developed for it. Therefore, the author has decided to come in on Mr. Tnay Chiat Siang’s quadruped project and continue his work to develop a control system which will eventually drive the quadruped robot to perform crawling gait on flat and horizontal ground. The control system of quadruped involves gait control, stability control and motor control. This project is split to three phases. The timeline of each phase is that phase 1 is carried out at semester FYP 1 while phase 2 begins during the year-end semester break. Phase 3 is commenced during FYP 2. The work aspect of phase 1 is on schematic design and crawling gait planning of quadruped. A preliminary simulation is used to demonstrate the planned crawling gait. The focus of phase 2 is more on learning how to manipulate PIC microcontroller and servomotors. At last, phase 3 is the prototype fabricating and testing stage with the presence of servomotors and circuit board. At the end of project, the quadruped prototype is meant to perform forward crawling gait on flat and horizontal ground

A STUDY OF THE KEY ELEMENTS IN VIRAL MARKETING TOWARDS CONSUMERS’ PURCHASE INTENTION IN KLANG VALLEY, MALAYSIA

This study investigates the critical elements of viral marketing toward consumers' purchasing intention in the Klang Valley, Malaysia. Five perceived viral marketing elements were identified and tested on their relationship to consumers' purchase intentions. The five key factors are perceived informativeness, entertainment, irritation, source credibility, and incentive. To gather and analyse the data related to this study, questionnaires were distributed through the online google platform to the consumers in Klang Valley. A total of 434 respondents contributed to the discussion and conclusion of this study. These respondents are frequent internet users who are familiar with viral marketing. Therefore, it increased the research's credibility. Findings obtained from this study indicated that four key elements of viral marketing, perceived informativeness, perceived entertainment, perceived source credibility, and perceived incentives, are significant and display a positive relationship to consumers' purchasing intention. In contrast, this study illustrated that perceived irritation is not significant for consumers' purchase intentions, indicating that the consumers in the Klang Valley, Malaysia, do not perceive the advertising messages targeted at them causes any annoyance but as helpful during their purchase intention.  Article visualizations

Genetic diversity and C2-like subgenogroup strains of enterovirus 71, Taiwan, 2008

<p>Abstract</p> <p>Background</p> <p>Human enterovirus 71 (EV-71) is known of having caused numerous outbreaks of hand-foot-mouth disease, and other clinical manifestations globally. In 2008, 989 EV-71 strains were isolated in Taiwan.</p> <p>Results</p> <p>In this study, the genetic and antigenic properties of these strains were analyzed and the genetic diversity of EV-71 subgenogroups surfacing in Taiwan was depicted, which includes 3 previously reported subgenogroups of C5, B5, and C4, and one C2-like subgenogroup. Based on the phylogenetic analyses using their complete genome nucleotide sequences and neutralization tests, the C2-like subgenogroup forms a genetically distinct cluster from other subgenogroups, and the antisera show a maximum of 128-fold decrease of neutralization titer against this subgenogroup. In addition, the subgenogroup C4 isolates of 2008 were found quite similar genetically to the Chinese strains that caused outbreaks in recent years and thus they should be carefully watched.</p> <p>Conclusions</p> <p>Other than to be the first report describing the existence of C2-like subgenogroup of EV-71 in Taiwan, this article also foresees a potential of subgenogroup C4 outbreaks in Taiwan in the near future.</p

Prognostic Value of Leucocyte Telomere Length in Acute Myocardial Infarction

Introduction: Leucocyte telomere length (LTL) has been described as a marker of biological age, endothelial dysfunction and atherosclerosis. The association between LTL and clinical characteristics of Asian patients, and their outcomes following acute myocardial infarction (AMI) have been inconclusive. Objective: To investigate the relationship between LTL and developing AMI, the association of LTL with inpatient and 30-day mortality, and the comparison to LTL with established AMI risk scores in predicting these outcomes. Methodology: 100 patients aged 30-70 years admitted with an AMI to a tertiary referral center between May-Oct 2017 were enrolled; these were matched with 100 non-AMI ('healthy') controls for gender and age (+/- 1 year). Clinical data was obtained prospectively; inpatient and 30-day outcomes documented. LTL was reflected by a well described variable called a tis ratio (TSR). The TSR was measured at enrolment using a quantitative PCR-based methods (qPCR) and results blinded to the clinician

RET Mutational Spectrum in Hirschsprung Disease: Evaluation of 601 Chinese Patients

Rare (RVs) and common variants of the RET gene contribute to Hirschsprung disease (HSCR; congenital aganglionosis). While RET common variants are strongly associated with the commonest manifestation of the disease (males; short-segment aganglionosis; sporadic), rare coding sequence (CDS) variants are more frequently found in the lesser common and more severe forms of the disease (females; long/total colonic aganglionosis; familial)

Real-time Monitoring for the Next Core-Collapse Supernova in JUNO

Core-collapse supernova (CCSN) is one of the most energetic astrophysical events in the Universe. The early and prompt detection of neutrinos before (pre-SN) and during the SN burst is a unique opportunity to realize the multi-messenger observation of the CCSN events. In this work, we describe the monitoring concept and present the sensitivity of the system to the pre-SN and SN neutrinos at the Jiangmen Underground Neutrino Observatory (JUNO), which is a 20 kton liquid scintillator detector under construction in South China. The real-time monitoring system is designed with both the prompt monitors on the electronic board and online monitors at the data acquisition stage, in order to ensure both the alert speed and alert coverage of progenitor stars. By assuming a false alert rate of 1 per year, this monitoring system can be sensitive to the pre-SN neutrinos up to the distance of about 1.6 (0.9) kpc and SN neutrinos up to about 370 (360) kpc for a progenitor mass of 30$M_{\odot}$ for the case of normal (inverted) mass ordering. The pointing ability of the CCSN is evaluated by using the accumulated event anisotropy of the inverse beta decay interactions from pre-SN or SN neutrinos, which, along with the early alert, can play important roles for the followup multi-messenger observations of the next Galactic or nearby extragalactic CCSN.Comment: 24 pages, 9 figure
