The formulation of the HSIADE method is also derived. Some numerical experiments are conducted that to verify the HSIADE method is more efficient than the Full-Sweep method.

The higher-order finite difference scheme is developed by representing the spatial derivative in the heat equation with the fourth-order finite difference Crank-Nicolson approximation. This leads to the formation of pentadiagonal matrices in the systems of linear equations. The algorithm also employs the higher accuracy of the Mitchell and Fairweather variant. Despite the scheme’s higher computational complexity, experimental results show that it is not only capable of enhancing the accuracy of the original corresponding method of second-order (IADEMF2), but its solutions are also in very much agreement with the exact solutions. Besides, it is unconditionally stable and has proven to be convergent. The IADEMF4 is also found to be more accur...

The existing method, Finite-Difference Time-Domain (FDTD) have been proven to solve the problem accurately, however, one of the drawbacks of the method was it needs a long processing time to simulate problem. Research efforts to increase the speed of simulating the problem are needed. Approach: Our recent research had found a new method with lower complexity and can simulate the problem faster than the existing FDTD algorithm. The method was developed by implementing the second order accurate discretization technique. But the method, which was named as the High Speed Low order finite-difference timedomain, had lower accuracy than the existing one. In this study, we reported on our new finding which used the O(h 4) truncation error rather than O(h 2) in our previous method. Results: The result found that we managed to recove...

Antara contoh inovasi dalam bidang teknologi maklumat adalah seperti teknologi pengimejan perubatan, teknologi laser dan nanoteknologi. Teknologi pengimejan perubatan adalah penting kerana dapat membantu pakar perubatan menjalankan pemeriksaan ke atas pesakit.Format teknologi imej perubatan dikenali sebagai DICOM. Format DICOM adalah unik kerana bukan hanya mengandungi gambar pesakit, tetapi juga mengandungi maklumat yang berkaitan dengan pesakit. Makalah ini menunjukkan proses pembangunan perisian bagi mendapat maklumat daripada gambar sinar-x digital (DICOM). Perisian dibangun dengan mengguna Netbeans dan perpustakaan yang diguna ialah DICOM Standard perpustakaan.

In order to achieve successful utilization, a number of factors may be taken into consideration from different perspectives depending on the real needs in the context of usage. Healthcare context still needing the utilization of new trend technologies such as utilizing cloud computing services to handle different tasks in this domain. The cloud services can offer a reliable solution to manage, maintain and retrieve health records within hospitals as well as to share the activities among hospitals and healthcare specialists. This allows the healthcare professionals to access, manage, and monitor patient’s health status anywhere at anytime. In order to make sure to get the full benefits of the new services, a prior examination in the context of usage must be applied to examine the current needs and the suitability of the technology. Therefore, the researchers in the present study trying to provide the suitable factors/domains used in the context of technology utilization in healthcare sector. A literature survey has carried out to check the suitability of the organizational structure and system settings and their impact on the healthcare members’ perception to utilize cloud health information systems. A total of 75 previous studies that used the proposed domains in different contexts has been included. Along with that, the researchers found that the studies in the context of technology utilization usually used three theories to combine the relationship between the above-mentioned domains. These theories are the Organization theory, Diffusion of Innovation theory and the Theory of Reasoned Action. Finally, the association between domains and the theories have been established.

The proposed architecture design unifies two existing MSPC techniques which are Hotelling’s T and MEWMA control charts that features a helpful graphical user interface (GUI). An architecture of real-time multivariate statistical process control (MSPC) system and a algorithm is also propose in this paper for subgroup data and individual observation scenarios. With the real-time multi-channel hardware sensors (Vernier LabPro) that interfaced directly to a client platform via universal serial bus (USB) or RS232 serial, it is dedicated to monitoring and controlling the multivariate process with this real-time data collecting.
