Modelling and design smart controller of magneto rheological using bouc-wen and sim model for motorcycle suspension system

Suspension system is a type of structural equipment attached to the wheels of a vehicle for the purpose of reducing the effects of irregularities on road surfaces. This paper investigates the Magneto rheological (MR) suspension system in motorcycle and compares its advantages with the passive suspension system. Passive suspension element can only store and dissipate energy associated with local relative motion. Moreover its energy cannot be controlled as the suspension properties remain fixed at all time, unlike MR suspension which has the ability to overcome these drawbacks. The characteristic of the latter is related to micron-sized particles, typically iron, that forms particle chains, when appropriate electric field is applied. Two modelling approaches which are the Bouc-Wen model and Sim models, were used in this research. By comparing these two MR models and passive suspension system, it can be concluded that the Bouc-Wen model gives the best result. It is also shown that MR suspension systems reduce the displacement amplitude around 30% whereas the time settling is reduced from 10 to 3 seconds, compared to the passive suspension system

Interoperability and Reliability of Multiplatform MPLS VPN: Comparison of Traffic Engineering with RSVP-TE Protocol and LDP Protocol

One of the alternatives to overcome network scalability problem and maintaining reliability is using MPLS VPN network. In reallity, the current network is already using a multiplatform of several different hardware vendors, i.e., Cisco and Juniper platforms. This paper discusses the comparison of the simulation results to see interoperability of multiplatform MPLS VPN andreliability through traffic engineering using RSVP-TE and LDP protocols. Both the RSVP and LDP protocols are tested on a stable network and in a recovery mode,as well as non-load conditions and with additional traffic load. The recovery mode is the condition after the failover due to termination of one of the links in the network. The no-load condition means that the network is not filled with additional traffic. There is only traffic from the measurement activity itself. While network conditions with an additional load are conditions where there is an additional UDP packet traffic load of 4.5 Mbps in addition to the measurement load itself. On a stable network and without additional traffic load, the average delay on LDP protocol is 59.41 ms, 2.06 ms jitter, 0.08% packetloss, and 8.99 Mbps throughput. Meanwhile, on RSVP protocol, the average delay is 52.40 ms, 2.39 ms jitter, 12.18% packet loss, and 7.80 Mbps throughput. When failover occurs and on recovery mode, LDP protocol is48% of packet loss per 100 sent packets while on RSVP packet loss percentage is 35.5% per 100 sent packets. Both protocols have interoperability on the third layer of multiplatform MPLS VPN, but on heavy loaded traffic condition, RSVP protocol has better reliability than the LDP protocol

Implementation of Single Minutes of Exchange Die (SMED) in Malaysia Metal Stamping Industry: A Case Study

Downtime loss due to long set-up time will lead to shorter actual production time. This situation will result in a loss to the company because they could not produce their products as planned. Therefore, set-up time needs to be reduced to maximize the resources invested by the company. The most popular approach to is an approach to improve setup time is Single Minutes of Exchange Die (SMED), developed by Shigeo Shingo in early 1960s. Setup operations were divided by into fundamental types; Internal setup and External setup. By Converting Internal setup to External setup, the company can reduced the setup time and thus, lead to longer actual production time. This paper presents an afford of a Malaysia’s metal stamping company in implementing SMED in their company. The company is a supplier of passenger car’s components to Malaysia’s major car makers. The implementation was carried out by separating Internal and External Setup, converting Internal to External Setup and finally streamlining all aspects of the setup operation. After implemented SMED approach, the company managed to reduce their set-up time from 32 minutes to 12 minutes. However, the company still working hard to achieve the objective of SMED, which is to complete all changeovers are in a single number of minutes or less than 10 minutes

Factors associated with emergency department green zone utilization in hospital

Introduction: In hospital, emergency departments are highly utilized by patients. Overcrowding, congestion and long waiting time were among the issues highlighted resulting from it. In Selangor, there has been a steady increase in utilization of emergency department of government hospitals over the past five (5) years. Utilization of green zone was the highest in these hospitals. Being a department that provides a comprehensive emergency service and provides easy access for the community, issues of appropriateness utilization arise. This study aims to determine the level of appropriateness of green zone utilization by patients attending Emergency Department in Serdang Hospital and factors influencing its utilization. Methodology: A cross-sectional study was conducted in Emergency Department of Serdang Hospital. Sample sizes of green zone adult patients were obtained by systematic random sampling. Emergency Medicine and Trauma Services Policy Malaysia 2012 were used to classify patients to appropriate and inappropriate utilization of green zone. Pre-tested self-administered questionnaire were used to interview patients. Descriptive statistics, chi-square test and logistic regression used to analyse the data collected. Data analysis conducted using IBM SPSS Statistics version 22 and p value significant at <0.05. Result: There were 793 (90.7%) patients in this study. It was found that level of appropriateness utilization in green zone emergency department was 83.6% appropriate and 16.4% was inappropriate. Median age of patients were 29 years old (IQR ± 25th, 75th; 23, 40). Majority were Malays (74%). The results of chi-square test indicated that there were significant association between marital status (p=0.032), patients attending emergency department because treatment cost is cheap (p=0.025), emergency department operates 24 hours (p=0.045) and time of patient presentation to emergency department (p=0.001). From the study, the multivariate results revealed that the odds of married patients (AOR=1.481, 95% CI: 1.008, 2.174) to utilize the emergency department were higher than not married patients, the odds of patients utilize emergency department not because of the cheap treatment (AOR=1.614, 95% CI: 1.073, 2.469) was almost two times more and lastly the odds of utilization after office hours were two times more than during office hours (AOR=2.117, 95% CI: 1.388, 3.227). Conclusion: The study revealed majority of patients utilized green zone appropriately. Married patient, patient attend emergency department not because treatment cost is cheap and patient attending after office hour were significantly associated with appropriateness utilization of emergency department. Further study needed to determine the cause and effect relationship

Flow induced vibration of a square cylinder with high scruton number

Flow over a square cylinder is numerically studied to understand the effect of reduced velocity to the transverse oscillation under the influence of high Scruton number elastic system of 4.316. For low reduced velocities, the transverse oscillation behavior can be grouped in the initial branch region. In this region, the motion is mainly controlled by the lift fluctuation. For intermediate reduced velocities, the transverse oscillation behavior is grouped in the lower branch region. In this region, its natural frequency slowly becomes significant. For high reduced velocities, the galloping region is observed. In this region, the natural frequency dominated the shape of the amplitude oscillation

Control of glycosylated hemoglobin (HBA1C) among type 2 diabetes mellitus patients attending an urban health clinic in Malaysia.

Diabetes mellitus is a public health problem and has become a concern to all levels of society. In Malaysia, the prevalence of diabetes mellitus had increased, from about 0.65% in early 1960s to 2 – 4% in 1980s and 14% in early 21st century. Studies had showed that glucose control is effective in preventing complications from diabetes mellitus. Level of glycosylated hemoglobin (HbA1c) is an accepted indicator of glycaemic control. A cross- sectional study was carried out to determine the level of control of HbA1c among 307 type 2 diabetes mellitus patients attending the health clinic in Bandar Tun Razak, Kuala Lumpur using validated structured questionnaires, while secondary data were obtained from patients’ medical reports. Response rate for this study was 89%. Majority of type 2 diabetes mellitus patients attending the health clinic in Bandar Tun Razak were Malays (79.5%), women (61.9%) and married (77.2%), and with secondary education (49.5%). The mean age of respondents was 56.9 ± 9.5 years, median Body Mass Index (BMI) was 28.5 (IQR: 6.0) and median HbA1c was 7.4% (IQR: 2.7). About three quarter of the type 2 diabetes mellitus patients studied had poor controlled level of HbA1c (≥6.5%). Age (p=0.047), blood pressure (systolic blood pressure p=0.049, and diastolic blood pressure p=0.011) and low density lipid level (p=0.039) had significant relationship with the level of HbA1c. Other risk factors studied had no significant relationship with the level of HbA1c. The study concluded that, there was poor glycaemic control among type 2 diabetes mellitus studied, this exposed them to complications of diabetes mellitus. It is recommended that health education activities, counselling and prevention activities are intensified and targeted to this group of patients
