Achieving excellence through information literacy as part of innovative curriculum

A great responsibility facing education today is to develop students with information literacy while pursuing their education and extend it further in their workplace. In order for today's students to excel in the 21st century, they must be able to acquire, evaluate, and use and present information effectively. They must become information literate workers, teachers, facilitators and coachers. Information literacy skills allow the problem solving, critical and creative thinking, decision making, and cooperative learning that prepare students for the challenges in society. Information literacy leads to skilful, responsible thinking that facilitates good judgement because it relies on criteria, is self-correcting and is sensitive to context. It helps growth of individuals through a number of methods, programmes and techniques. It would be useful if the educational incorporate these elements since the elementary stage so that by the time their reach the college and university level, they have acquired the reading and information skills much required in the current information and knowledge era

Strategy of managing knowledge in organizations / Raja Abdullah Yaacob, Hazeman Ahmad and Raja Ahmad Iskandar

In organizations, knowledge can be beneficial in the business process by save costs and time. Organization needs to understand its business, its mission and vision before strategy can be made. Increasing number of organizations have recognized the need for systematically managing knowledge, hence the application of knowledge management in their management system. This paper identifies and discusses the important of mission and vision to generate strategies and what strategy should be used for organizations to manage knowledge with some case studies

Thyroglossal duct carcinoma

We report a 56-year-old Malay woman with a tumour that involved the skin and caused hyoid bone erosion. There was no clinical or radiological evidence of regional lymph node involvement. A modified radical neck dissection with preservation of the accessory nerve and internal jugular vein was performed, followed by an "extended" Sistrunk operation. The surgical defect was reconstructed with a pectoralis major myocutaneous flap. Our literature review showed that this is the first reported thyroglossal duct carcinoma which involved the skin and required a pedicle flap reconstruction

A ground based circular synthetic aperture radar

Detecting on-the-ground objects is a subject of interest for some applications. Typical example is foreign object detection on the airport runway. In response to this demand, a ground-based Circular Synthetic Aperture Radar (CSAR) system is proposed and explained in the paper. In the proposed CSAR, the antennas represent a circular movement trajectory. Wideband Linear Frequency (LFM) chirps were used for transmission. A simulation model for CSAR, based on the Doppler Effect between the radar and object is developed in this paper. In addition, a processing method for object detection using correlation between image data produced by simulation and experimental data is developed. The resultant of the simulated model at each point, which represents the object's behavior in an ideal and clutter-free environment, is used as a template for object detection. Simulation and experimental results demonstrate that the proposed method is well suited in detecting small objects at different positions

Face recognition using assemble of low frequency of DCT features

Face recognition is a challenge due to facial expression, direction, light, and scale variations. The system requires a suitable algorithm to perform recognition task in order to reduce the system complexity. This paper focuses on a development of a new local feature extraction in frequency domain to reduce dimension of feature space. In the propose method, assemble of DCT coefficients are used to extract important features and reduces the features vector. PCA is performed to further reduce feature dimension by using linear projection of original image. The proposed of assemble low frequency coefficients and features reduction method is able to increase discriminant power in low dimensional feature space. The classification is performed by using the Euclidean distance score between the projection of test and train images. The algorithm is implemented on DSP processor which has the same performance as PC based. The experiment is conducted using ORL standard face databases the best performance achieved by this method is 100%. The execution time to recognize 40 peoples is 0.3313 second when tested using DSP processor. The proposed method has a high degree of recognition accuracy and fast computational time when implemented in embedded platform such as DSP processor

A Linear Frequency Modulated bistatic radar for on-the-ground object detection

A radar system for detecting and localizing small targets on the ground is proposed in this paper. The system transmits wideband Linear Frequency Modulated pulses from ground-based transmitter. The reflected pulses will be collected simultaneously by two different ground-based receivers installed in different bistatic positions. Accurate range processing in this bistatic configuration will lead us to detect small objects like N-type connectors in several meters distances

An experimental investigation for Foreign Object Detection application has been analysed

Moving target detection by using new LTE-based passive radar

This paper examines the feasibility of LTE-based passive radar for detecting ground moving targets. Specifically, the focus of this paper is to describe the proposed LTE-based passive radar system and to conduct an experiment using a real LTE eNB transmitter as an illumination source. Seven scenarios were carried out to investigate the detection performance of the proposed system on ground moving targets with different speeds, trajectories and range. In addition, multi-target detection was also tested. The experimental results showed that the LTE-based passive radar system has the capability to detect typical ground targets/objects like cars, motorbikes and humans moving at different trajectories. The positive results opened up a new frontier for passive radar systems to be used in many potential applications, including security, border protection, microwave fences, monitor of buildings and others

Foreign object detection based on circular bistatic synthetic aperture radar

Synthetic Aperture Radar is well known for producing a radar image of the ground, so it can be used for detecting on-the-ground object which is interesting for some applications. A possible application can be Foreign Object Detection (FOD), which is an important issue in aviation safety. A ground-based Circular Bistatic Synthetic Aperture Radar (Circular-BiSAR) is introduced in this paper. The circular movement makes it more practical while the bistatic configuration offers some advantages. Wideband Linear Frequency Modulated (LFM) chirp pulses are employed here, for transmission and reception of reflection pulses to and from the under test object. A simulated model is developed for the system which analyzes the transmitting, receiving, Doppler and LFM signals by considering the distances and movement of antennas. A prototype system is launched, and some experiments are done to detect and localize various objects based on their reflection properties of microwaves. A processing algorithm is proposed in this paper to confirm the detection. The results show that the proposed system can detect and localize on-the ground objects with as small a dimension as 2 cm height and 2 cm diameter located several metres away

Demand for fish and its substitutes in Malaysia: evidence of habit formation and structural change

This paper addresses the issue of changes in consumers' tastes in the demand for fish and meat products in Malaysia. Both, habit persistent effect and structural change in consumers' preferences towards fish and its substitutes are empirically examined using data from 1960 to 1990 with an Almost Ideal Demand System (AIDS) approach. In the dynamic AIDS model, it was found that there was a pervasiveness of habit formation in the demand for fish, chicken and pork but the amount of beef and mutton purchased during the last period tends to lower current budget allocation on these meat products. The structural change in consumers' preferences were tested using CUSUMSQ procedure and it was found that there was no structural break in the fish equation. This indicates that consumers' tastes do not change with respect to fish, consistent with a priori expectation, but the more health-conscious population are changing their preferences away from the red meats and currently demanding a bigger amount of white meat, which includes fish
