In this paper, different tracking control schemes are studied for magnetic levitation system. An input-output linearization feedback controller is designed by incorporating integral gain in feedback path that makes the error more symmetrical and provides very good tracking performance. The previously proposed input-output linearization feedback controller with state feedback gains only, generates non symmetrical error when implemented on the real time system. Pole placement technique is used to calculate the feedback gains by linearizing nonlinear system. A sliding mode controller and PID controller are also implemented for comparison. Control schemes are simulated and satisfactory results are achieved. Finally, a real time implementation of the controllers is carried out for experimental verification and comparison of these designed schemes.

Ontology learning is considered a potential approach that can help to reduce the bottleneck of knowledge acquisition. However it suffers from a lack of standards to define concepts, besides the lack of fully automatic knowledge acquisition methods. In performing this learning process, the discovery of non-taxonomic relationships has been identified as being the most difficult. This study is then an attempt to create an enhanced framework for discovering and classifying ontological relationships by using a machine learning strategy. We take into consideration the context of the input text in performing the classification of the semantic relations, in particular, causation relations. The proposed framework extracts initial semantic patterns for causation relation from the input samples, then filters these patterns using two novel algorithms, namely, the “Purpose Based Word Sense Disambiguation” which helps in determining the causation senses for input pair of words and the “Graph Based Semantics” which determines the existence of the causation relations in the sentence and to extract their cause-effect parts. The results show a good performance and the implemented framework cut off many steps of the usual process to produce the final results.

This paper examines the energy efficiency of a hydrogen fuel cell vehicle operating at different power settings. The goal is to develop a driving strategy to maximize energy efficiency for a fixed distance and average velocity. The test vehicle is equipped with a proton exchange membrane (PEM) fuel cell system that provides electric power to a brushless DC motor. This vehicle was designed to compete in the Shell Eco Marathon, an international competition in which the winners are the teams that go the furthest using the least amount of energy. A computer model that simulated the motor and vehicle dynamics was used to predict the output power demanded from the fuel cell. An actual test was then conducted to verify, compare and analyze the performance of the motor for various speed ranges. The result showed how the efficiency varied for different vehicle accelerations. This data can then be used as a basis to operate the vehicle with optimal efficiency.

Energy efficiency implementing strategy requires various approaches for different condition to increase the effectiveness. The energy efficiency normally refers energy usage without wastage. Normally, certain reference or benchmarking to certain standard will be used such as building energy index (BEI). Two new indexes were introduced in this paper namely Effective Building Energy Index (EBEI) and Specific Building Energy Index (SBEI). This paper presents the benchmarking additional approach so as to reduce energy wastage in Engineering Complex, UiTM Shah Alam. BEI for this complexs was found to be 149 kWh/m2.year and EBEI is found to be 186 kWh /m2.year. The SBEI was found to be 0.207 kWh/m2.year for an occupant. With various approach discussed in this paper, an expected energy reduction of 20% can be achieved.

The motion of human body is complex but perfect and integrated effort of brain, nerves and muscles. Exoskeleton is a promising idea for human rehabilitation of the lower limb that is weak enough to move. EMG signal contains the information of human movement and can be considered as one of the most powerful input to exoskeleton controller. In this research, the activity of the lower limb muscles that are responsible for human sit to stand and stand to sit movement has been studied. In this regard, the activities of three muscles viz. rectus femoris, vastus lateralis and biceps femoris have been observed and recorded to perceive their activation pattern. The experimental results show that the maximum voltage of vastus lateralis at activation moment is greater or equal to +0.1 mV or lesser or equal to -0.1 mVduring sit to stand and stand to sit movement whereas same throughput was found for biceps femoris during sit to stand and for rectus femoris during stand to sit movement only.

Feature detection is an important task for an autonomous vehicle in getting reference or guide in a agriculture field. Recently, a lot of sensors were implemented for feature detection of a field such as sonar sensor, laser range finder, infrared sensor which it is used as height estimation, size area measurement and path tracking that act as reference for desired measurement in creating a virtual map of the agriculture field which can be used as autonomous vehicle navigation process. A vision based sensor is implemented on the unmanned area vehicle for low altitude mapping. Real-time process with minimum computational process and light weight devices is required and utilized as it used UAV as the transportation element. An experimental setup utilized an analog camera as the front end sensor for the desired detection. The experimental surface is scanned by the analog vision sensor for sensor accuracy analysis used for feature detection application. The process technique is implemented via the medium speed 16-bit processor microcontroller which avoids the requirement of high-speed processor to do image processing. The vision sensor will be utilized into an unmanned aerial vehicle used for feature detection scheme for field measurement. The composing image produced is shown for comparison with the actual image as for performance analysis of the vision based sensor. The designed technique gave acceptable error of image accuracy that adequate to use for features detection on unmanned aeria vehicle.

This paper presents the thin-film performance with a total nominal array of 0.9 kWp Grid-Connected Photovoltaic system using single-junction amorphous-Silicon for two years of operation in Malaysia. Since the operation, the system has injected into the Tenaga Nasional Berhad's grid with the total energy production of about 2,232.8 kWh. Additionally, the daily average for the final PV system yield, the efficiencies of system and inverter were recorded at 3.39 kWh/kWp.d, 5.08% and 89.6%, respectively. The daily operation showed that it has been operating in better condition under Malaysian climate with the performance ratio measured at 80.6% during the monitored period.

Performance indicator is important as a comparison for improvement in any form of technology. It provides the direction for technology improvement. For photovoltaic system, the normal indicator for performance is the performance ratio while for the solar cells, the cell efficiency is normally being used. This paper will analyze the use of performance ratio as a performance indicator for a system. The analysis and discussion will provide the rationale for using performance ratio as an indicator for photovoltaic performance but performance ratio alone is not good enough. For the period of one year from April 2012 to March 2013, the performance ratio for monocrystalline was 77% while for polycrystalline was found to be 80%. Solar cell efficiency was found to be 11.8% for monocrystalline and polycrystalline to be 11.5%. Higher performance ratio just indicates the energy yield compared to the expected energy yield.

Automatic Optic Disc (OD) removal is vital step prior to screening Diabetic Retinopathy (DR) cases. Hence in this paper, we proposed an automated technique for removal of OD position in digital retina fundus images based on mathematical morphological operations. Here, dilation and erosion to remove OD and enhance the appearance of binary images. The proposed technique was tested on 400 images of the publicly available MESSIDOR database. Experimental Results showed that OD can be effectively be removed from the binary images and the proposed method is robust too.
