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.
Role of nitric oxide in management of acute respiratory distress syndrome
Akmal A,Hasan Mohd
Annals of Thoracic Medicine , 2008,
Abstract: The current mortality rate of patients suffering from acute respiratory distress syndrome (ARDS) is between 45% and 92%, with most dying within the first two weeks of the illness. In an effort to combat such an alarmingly high mortality rate, various treatment therapies such as low tidal volume ventilation strategies, corticosteroid therapy, and use of nitric oxide (NO) have been attempted in the management of patients with ARDS. Three cases which were admitted to the ICU and confirmed to have ARDS were unable to be weaned from ventilatory support, and nitric oxide therapy was initiated. It improved patients′ oxygenation for short periods of time but did not affect the mortality. The patients could not be weaned from the ventilator and expired.

Chin Kat Meng, Nasri A. Hamid, Mohd. Yusri Abd. Rahman
Natural Science (NS) , 2011, DOI: 10.4236/ns.2011.31004
Abstract: Superconducting electrical devices have been developed in various fields especially in industrial energy over a decade. Superconducting motor is one of the electrical devices that attracted the attention of engineers and researchers from the universities and industries due to its distinctive energy efficiency. This paper describes the performance of superconducting electric motor and its performance was compared with conventional copper electric motor. Direct current (DC) synchronous single- phase series motor has been chosen as the base for development of both motors. Two prototypes of electric motor fabricated using conventional copper coil and superconducting coil were developed with similar motor type, design, dimension, and features. The superconducting motor coil was wound using Bi-2223 (DI-BSCCO) Type H wires developed by Sumitomo Electric Industries Limited, Japan. A finite element analysis was performed to get a clear view on flux plots of the magnetic induction. Features of the superconducting motor and the special coil frame designed to protect the superconducting wire was also presented in this paper. In addition, the torque performances for both types of motor were measured. The superconducting electric motor was found to consume lower power to produce the same output compared with the conventional copper-wound motor.
Mechanical and superconducting properties of nanosize MgO added dip-coated Bi2Sr2CaCu2O8 superconducting tape  [PDF]
Nasri A Hamid, Mohd Yusri Abd Rahman, Noor Fairuz Shamsudin
Natural Science (NS) , 2011, DOI: 10.4236/ns.2011.36067
Abstract: In this work, 3% to 8% (in weight) of nanosize MgO particles was added to Bi2Sr2CaCu2O8 (Bi- 2212) high-temperature superconductor to fab-ricate Bi-2212 superconducting material with superior mechanical properties. The mechanical strength of the samples was studied by con-ducting the compression test at room tempera-ture, and the addition of 5% nanosize MgO par-ticles produced the highest strength when com- pared with other samples. The sample with 5% MgO addition also exhibited superior super-conducting properties. The Bi-2212 powder with 5% nanosize MgO addition was used to fabricate Bi-2212 tapes through the dip-coating-then- stacking method. The fully processed tapes were investigated via dc electrical resistance measurements, XRD patterns, SEM micrographs, transport critical current density and tensile tests. The tensile tests were conducted at room and cryogenic (77 K) temperatures. Results of tensile tests and Young’s modulus for the tapes showed that the Bi-2212 tapes with nanosize MgO addition recorded better mechanical prop-erty compared to the non-added samples both at room and cryogenic temperatures. The double- core tape with 5% MgO addition recorded the highest failure point at 160 MPa. In addition to the strengthening effect that was observed in the nanosize MgO added Bi-2212 superconduc-tor tapes, the superconducting properties re-mained intact in the tapes.
Selection of a Suitable Wavelet for Cognitive Memory Using Electroencephalograph Signal  [PDF]
S. Z. Mohd Tumari, R. Sudirman, A. H. Ahmad
Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.55B004
Abstract: The aim of this study is to recognize the best and suitable wavelet family for analyzing cognitive memory using Electroencephalograph (EEG) signal. The participant was given some visual stimuli during the study phase, which were a sequence of pictures that had to be remembered to acquire the EEG signal. The Neurofax EEG 9200 was used to record the acquisition of cognitive memory at channel Fz. The raw EEG signals were analyzed using Wavelet Transform. A lot of mother wavelets can be used for analyzing the signal, but do not lose any information on the wavelet, some predictions must be made beforehand. The criteria of the EEG signal were narrowed down to the Daubechies, Symlets and Coiflets, and it is the final selection depending on their Mean Square Error (MSE). The best solution would have the least difference between the original and constructed signal. Results indicated that the Daubechies wavelet at a level of decomposition of 4 (db4) was the most suitable wavelet for pre-processing the raw EEG signal of cognitive memory. To conclude, choosing the suitable wavelet family is more important than relying on the MSE value alone to successfully perform a wavelet transformation.

Shafkat A. Lone, Mohd. Lateef
JK Science : Journal of Medical Education & Research , 2004,
Abstract: A two year experience with the treatment of 50 patients (86% children) who were admitted forforeign body aspiration in the department of otorhinolaryngology and Head and Neck Surgery isreviewed. The object of this study was to show the clinical manifestations, the radiological findings,the nature and distribution in the tracheobronchial tree and complications due to long standing foreignbodies in the bronchial tree. Males (35) were more commonly involved as compared to females (15)in the ratio of 2.3:1. Right main bronchus was involved in 24 patients (48%), left main bronchus in 15patients (30%) and trachea in 11 patients (22%). The most common foreign bodies found werebeans (24%), peas (18%), and corns (10%). The most frequent clinical manifestation was choking(60%) and the most frequent radiological finding was atelectasis (44%). The most serious complicationwas pneumothorax in 2 patients who needed intercostal chest tube. In conclusion, inspite of anobvious foreign body in the tracheobronchial tree many cases are not diagnosed because suddenchoking at the time of aspiration in children may not be noticed.

Abdurahman H. Nour,Mohd A. Abu Hassan,Rosli Mohd Yunus
Journal of Applied Sciences , 2007,
Abstract: Many advances have been made in the field of emulsions in recent years. Emulsion behavior is largely controlled by the properties of the adsorbed layers that stabilized the oil-water surfaces. The effect of chemical demulsifiers in demulsification of water-in-crude oil emulsions were assessed experimentally. The relative rates of water separation were characterized via graduated beakers. Four groups of demulsifier with different functional groups were used in this work namely amines, polyhydric alcohol, sulphonate and polymer. The effect of alcohol addition on demulsification performance also studied. The results obtained in this study have exposed the capability of chemical demulsifiers in destabilization of water-in-crude oil emulsions. Further works are nevertheless required to provide deeper understanding of the mechanisms involved to facilitate the development of an optimum system applicable to the industry.
