Improved NCTF Control Method for a Two-Mass Rotary Positioning Systems  [PDF]
Mohd Fitri Mohd Yakub, B. A. Aminudin
Intelligent Control and Automation (ICA) , 2011, DOI: 10.4236/ica.2011.24040
Abstract: This paper describes an improvement of the existing nominal characteristic trajectory following (NCTF) as a practical control method for a two-mass rotary point-to-point (PTP) positioning systems. Generally, the NCTF controller consists of a nominal characteristic trajectory (NCT) and a PI compensator. A notch filter is added as a part of the compensator to eliminate the vibration due to the mechanical resonance of the plant. The objective of the NCTF controller is to make the object motion follow the NCT and end at its origin. The NCTF controller is designed based on a simple open-loop experiment of the object. The parameters identification and an exact model of the plant are not necessary for controller design. The performance response of improved NCTF controller is evaluated and discussed based on results of simulation. The effect of the design parameters on the robustness of the NCTF controller to inertia and friction variations is evaluated and compared with conventional PID controller. The results show that the improved NCTF controller has a better positioning performance and is much more robust than the PID controller.

Health (Health) , 2013, DOI: 10.4236/health.2013.58A2011
Abstract:

Autism is a neural development disorder characterized by the deterioration in social interacttion, abnormal language expression, repetitive actions, imaginative game tendencies, and limited and/or obsessiveness in certain activities/ interests. Lack of sleep is one of the factors contributing to the worsening of overall negative symptoms of autistic children. From the Islamic perspective, sleep is a necessity and could function as a treatment for health problems, in addition to influencing behavior patterns. Sound therapy has been used in dealing with various health problems, including sleep problems and mental ill health. Possibly, it can also address sleep problems of the autistic children. Listening to the melodious Qur’anic recitation is known to have therapeutic effects even on individuals who do not understand the meaning of the verses being read; it could function as sound therapy. However, no established work has been done to study the effect of Qur’anic verses recitation on autistic children and their sleep problems. Similar to the use of music therapy, Qur’anic recitation is also expected to have a positive impact on speech, learning and interpersonal relationship. As a healing medium, Qur’anic therapy is also expected to have a better result as compared to other conventional sound therapy since its content could be psychotherapeutic.

Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.71007
Abstract: This comparative study examined student thinking skills and their attitudes towards learning History. Respondents were pre-service teachers who enrolled in the History Education Program from two education universities in Malaysia and Indonesia. The historical thinking skills (HTS) and their attitudes examined in this study are: chronological skills, facts exploration skills, imagination skills, interpretation skills and rationalization skills. A set of questionnaire was used to gain data. Data analyses involved descriptive and inferential analysis. A Cronbach Alpha score obtained from a pilot indicated that all constructs were at a high reliability level (between 0.73 and 0.89). Data collection was carried out in Malaysia and Indonesia involving 260 respondents. The results of this study demonstrated that there was a high level of Historical Thinking Skills (HTS) among teacher trainees from both countries. Detailed result indicated that Malaysian teachers have a higher level of the following historical thinking skills: facts exploration, interpretation skills and rationalization. However, results show that that none of these historical skills have statistically differences. This means that historical skills among teachers in both countries are similar. Overall, the current study suggests intensive training to promote historical thinking skills among teacher trainees from both countries. Implication towards teaching practices is discussed.

Unaise Abdul-Hameed,Prateek Rangra,Mohd. Yakub Shareef,Mohd. Ejaz Hussain
Asian journal of Sports Medicine , 2012,
Abstract: Purpose: The 1-repetition maximum (1-RM) test is the gold standard test for evaluating maximal dynamic strength of groups of muscles. However, safety of actual 1-RM testing is questionable in clinical situations such as type 2 diabetes (T2D), where an estimated 1-RM test is preferred. It is unclear if acceptable test retest reliability exists for the estimated 1-RM test in middle aged T2D patients.This study examined the reliability of the estimated 1-RM strength test in untrained middle aged T2D subjects.Methods: Twenty five untrained diabetic males (n=19) and females (n=6) aged 40.7+0.4 years participated in the study. Participants undertook the first estimated 1-RM test for five exercises namely supine bench press, leg press, lateral pull, leg extension and seated biceps curls. A familiarisation session was provided three to five days before the first test. 1-RM was estimated for all participants by Brzycki 1-RM prediction equation. Another identical 1-RMestimation procedure occurred one week after first test. Intraclass correlation coefficients (ICC), paired t-test, standard error of measurement (SEM), Bland- Altman plots, and estimation of 95% CI were used to assess reliability.Results: Test-retest reliability was excellent (ICC2,1=0.98-0.99) for all measurements with the highest for leg extension (ICC2,1=0.99). The SEM was lowest for lateral pull and leg extension exercises. Paired t-tests showed nonsignificant differences between the means of 2 sessions across three of five exercises.Conclusions: The study findings suggest that estimation of 1-RM is reliable for upper and lower body muscular strength measurement in untrained middle aged T2D patients.

Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.59005
Abstract: Poverty is not something new issue for a country. Poverty is seen as a problem that could negatively impact on a country. Malaysia also cannot escape from this poverty problem. Malaysia is a country where the Moslem people are majority and they are permanent resident. Therefore, from the perspective of Islam, poverty had been seen as a social disease [1]. According to the post’ or scholars’ statement, one of the ways poverty can be overcome is the implementation of the community development program. One of the community development programs in Malaysia that for farmer and house hold that involve in agriculture is called AZAM Tani. A study was conducted on participants AZAM Tani (Agricultural AZAM) areas of Seberang Perai, Penang. AZAM are words in Malay language. It is also short form and stand for End Time of The Poor. The method used was census. A total of 54 respondents were found. The results showed that the AZAM Tani program is able to help increase knowledge. Then with the knowledge that the participants had, they are able to raise their level of skills. This can be seen in the results of Spearman correlation indicating the relevance of knowledge to the implementation of the program and the relevance of relationship knowledge and skills with r = 0.612, p < 0.05. This relationship is positive. The study also shows an increase in the income level of the respondents.
Comparing the Accuracy of Network Utilization Performance between Real Network and Simulation Model for Local Area Network (LAN)  [PDF]
Mohd Nazri ISMAIL, Abdullah Mohd ZIN
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2008, DOI: 10.4236/ijcns.2008.14042
Abstract: This article presents a novel approach for the measurement and estimation of network traffic utilization between network nodes in heterogeneous environment. This research investigates performance evaluation of network interface on heterogeneous services and technologies environment. This study proposes an enhanced equation to evaluate the performance of network interface via Little Law and Queuing theories to improve the evaluation algorithm. To get accuracy results on the performance of simulation model, it measures (verify and validate) data from Local Area Network (real network environment). This project uses network management tool to capture those data and Fluke Optiview device to generate traffic. As a result, this simulation model can provide a good approximation of the real traffic observed in the real network environment. Through laboratory and field experiments, the result shows that the model via simulation is capable of approximating the performance of network utilization and traffic over heterogeneous services and techniques within a minimum error range.

iBusiness (IB) , 2012, DOI: 10.4236/ib.2012.42015
Abstract: More than two decades, international entrepreneurship (IE) has come out as a distinct academic discipline, and that concentrates on firms that become international from inception or near after it. However, comparatively little is known about the international entrepreneurship (IE), its capability and what drives the international performance of these firms with early and rapidly internationalizations. Therefore, the objective of the investigation is to reveal the dimensions of international entrepreneurial capability (IEC) and its effect on international performance (IP) in born global firms. The study will give an instruction to the born global (BG) managers, vision and strategy to the policymakers, and introduce the effectiveness role of international entrepreneurship capability (IEC) on international performance.
Poly(Acrylamide-Co-Acrylic Acid)-Zinc Acetate Polymer Electrolytes: Studies Based on Structural and Morphology and Electrical Spectroscopy  [PDF]
Mohd Faiz Hassan, Siti Zulaikha Mohd Yusof
Microscopy Research (MR) , 2014, DOI: 10.4236/mr.2014.22005
Abstract:

Solid polymer electrolytes (SPEs) of polyacrylamide-co-acrylic acid (PAA) as the polymer host and zinc acetate (ZnA) as an ionic dopant were prepared using a single solvent by the solution casting technique. The amorphous and crystalline structures of film were investigated by X-ray diffraction (XRD). The surface morphology of samples was examined by scanning electron microscopy (SEM). The composition and complex formation of films were characterized by Fourier transform infrared (FTIR) spectroscopy. The conductivity of the PAA-ZnA films was determined by electrochemical impedance spectroscopy. According to the XRD and FTIR analyses, all electrolyte films were in amorphous state and the existence of interaction between Zn2+ cations and the PAA structure confirms that the film was successfully prepared. The SEM observations reveal that the electrolyte films appeared to be rough and flat with irregularly shaped surfaces. The highest ionic conductivity (σ) of 1.82 × 10-5 Scm-1 was achieved at room temperature (303 K) for the sample containing 10 wt % ZnA.
