Blood urea nitrogen (BUN) is an indicator of dehydration in patients at risk of developing acute stroke-in-evolution, and BUN level detection in such patients can help prevent such a diagnosis. This study developed the key module components of and techniques employed by a BUN analyzer that is suitable for use during home care. Based on suggestions by health professionals, an analyzer was developed,...
QR code is the commonly used two-dimensional (2D) barcode recently with the advantages of larger QR content and error correction capability. General QR reader can scan the contents of the QR code. When the content of the QR code is secret information, the information security becomes important. To protect the security of secret information, the new proposed method can embed secret information into...
The teaching materials used by Taiwanese students in class are compiled by different publishers according to the curriculum outline established by the Ministry of Education. However, limited by the layout of teaching materials, it is impossible to incorporate all knowledge referred by the curriculum outline into teaching materials, thus, some are selected and some are abandoned. For example, as the...
This paper proposes a Z-source inverter (ZSI) system for standalone photovoltaic generation system (PGS). The advantages of ZSI include high reliability, high efficiency, low cost and compact size. The operation principle, design considerartion and control method of the system will be presented. Experimental results will also be provided to validate the correctness of the proposed system.
In order to make mobile robot adapt to more intricate work environment, complete more complicated operation through the mechanical arm. This paper presents a robotic control system based on master-slave remote operation of mechanical arm. Firstly, to realize synchronization of the master-slave mechanical arm, controlling the slave mechanical arm to finish the same action by operating the master mechanical...
Test cases of original program could be reused in order to reduce cost of testing the modified program. The reusability of test cases is affected by the rewriting skills and test coverage criteria which are adopted in rewriting and testing process of modified program. This paper summarizes frequent rewriting pattern in rewriting program, and analyzes the effect of them in testing modified program...
Program call graph representation can be used to support many tasks in compiler optimization, program comprehension, and software maintenance. During software evolution, the call graph needs to remain fairly precise and be updated quickly in response to software changes. In this paper, we present an approach to incremental update, instead of exhaustive analysis of the initially constructed call graph...
The collaborative simulation for complex products needs seamless integration of multi-discipline tool software on collaborative simulation platform. However, many kinds of tool software do not provide application programming interface (API), which is vital for collaborative simulation. Under the technical framework of complex productspsila collaborative simulation platform, the paper proposes three...
Change impact analysis is a useful technique for software evolution. It determines the effects of a source editing session and provides valuable feedbacks to the programmers for making correct decisions. Recently, many techniques have been proposed to support change impact analysis of procedural or object-oriented software, but seldom effort has been made for aspect-oriented software. In this paper...
Aspect-oriented programming (AOP) is gaining popularity with the wider adoption of languages such as AspectJ. During AspectJ software evolution, when regression tests fail, it may be tedious for programmers to find out the failure-inducing changes by manually inspecting all code editing. To eliminate the expensive effort spent on debugging, we developed AutoFlow, an automatic debugging tool for AspectJ...
During the life time of software or even within the development stage, it is inevitable that the software needs to be modified. Test cases used before for the previous version could be reused in order to reduce the cost of regression testing. This paper proposes a regression testing methodology, called Partitioning of Domain Testing (PDT), to analyze the input domains of the previous version and the...
In this paper, we exploit the concept of sharing GPS data for estimate traffic information. Explicitly, we implemented CarWeb, a platform to collect real-time GPS data from cars. Once receiving a sufficient amount of GPS data from cars, we are able to estimate traffic information (i.e., speed information of roads). As such, users are able to obtain the update-to-date traffic information in CarWeb...
Modeling the grounding circuit with adequate accuracy is significant for studying conducted EMI problems caused by impedance of grounding net, while few researches has been done in this field. A simplified grounding model is introduced in this paper to represent grounding net. Several methods, including PEEC (partial element equivalent circuit), Ansoft Q3D, Maxwell 3D and FastModel are used to extract...
