“…It is worth mentioning that the DSPs are also equipped with embedded fused multiply/add which can be used for orthogonal transforms implementations such as discrete cosine transform (DCT), discrete Hartley transform (DHT) as well as others computation-intensive DSP functions like convolution, interpolation and adaptive filtering [33]. As a result, DSPs have been successfully used in a wide range of image processing applications [34][35][36][37][38][39].…”

A AbstractRecently, the more widespread use of three-dimensional (3-D) imaging modalities, such as magnetic resonance imaging (MRI), computed tomography (CT), positron emission tomography (PET), and ultrasound (US) have generated a massive amount of volumetric data. These have provided an impetus to the development of other applications, in particular telemedicine and teleradiology. In these fields, medical image compression is important since both efficient storage and transmission of data In summary, this research is tackling the issues of massive 3-D medical volumes data that requires compression as well as hardware implementation to accelerate the slowest operations in the system. Results obtained also reveal a significant achievement in terms of the architecture efficiency and applications performance.

The study presents an execution core which can be reconfigured either for calculation of digital convolution or for computation of discrete orthogonal transform by appropriate local buffer initialization of processing cells. It is shown that the data flow pattern can be changed by a single bit control signal. The proposed core can be connected to port 1 of Intel 8051 to derive the necessary control signals for reconfiguration. The core can be used as a pluggable module with existing microcontroller when DSP algorithms are required to be implemented. Using such execution core the computational load of the processor can be significantly reduced as the math-intensive components of the DSP algorithm is relegated to the execution core. The use of such pipelined core will not only caters to the need of real-time performance, but also it will facilitate scalability, reusability and flexibility for wide varieties of DSP functionalities

“…With the availability of more complex technique of data collection, observation study especially via embedded system is seen as more effective (El-Mousa and Al-Suyyagh, 2010;Rath and Meher, 2006;Rath and Dehuri, 2006). The development of instrument to deal with plagiarism in this study considers some important factors in physical specifications.…”

Problem statement: Course instructors are facing serious problems in dealing with students who plagiarize programs especially when the number of students in the course is high. Among the proposed approach to handle this problem is by using automatic detection of plagiarism in programming projects. Preventive action is required rather than curing the problem so that programming students get the right message from the beginning. Approach: To address this problem, a surveillance system was proposed to record every programming activity. It is developed in an integrated development environment so that programming activity profile in Java format is created when students are developing their Java program. A non-intrusive and non-experimental setting approach was applied in which hidden data collection is conducted to observe students' behavior in natural programming setting. Experimental study effect i.e., Hawthorne effect and effect of expectation on subject behavior was exploited as prevention on plagiarism. Surveillance system produces two file types: Activity log to keep programming activity log information and Backup file to save the program writing record. Results: The proposed programming activity surveillance system, DwiCoder presented a programming activity report at the end of each programming session. Students can assess their own progress in developing a program in these three activities: Compilation, execution and modification. The report was presented in a simple and meaningful way to encourage student spend their own time in programming activity. Conclusion: By using DwiCoder, student's programming activity is continuously monitored and their behavior is under control. This system provides an effective prevention method in tackling plagiarism.
