Reusability of a test suite is one of important factors to decrease the cost in software testing. This research defines and measures the test suite reusability score expressed with the degree of reusability of the test suite. It is calculated by considering both frequency and code coverage of successful reused test cases in the test suite. Test suite reusability measurement provides useful information to improve the efficiency of software testing, especially in regression testing and automated testing.

Large portion of rural small-scale farmers in Tanzania can't afford to buy quality agricultural inputs (fertilizers and seeds), therefore the government of Tanzania provides these farmers with paper-based subsidy vouchers which allow them to buy the agricultural inputs at only half price. However, challenges like misuse of the vouchers by some government officials (stealing and favoritism in vouchers' allocation) and lack of trust (difficulty of verifying vouchers' authenticity) have resulted into low crop productivity for the farmers and loss of government funds. In our previous work, we developed agricultural input voucher system which stores and allocates digital subsidy vouchers to farmers in the Hyperledger Fabric blockchain network and we evaluated its performance based on transaction throughput and latency metrics which are important to farmers, who access the system through Short Message Service (SMS) in their mobile phones. The blockchain network's features such as hashing and digital signature prevent misuse and ensure trust of the digital vouchers. In this paper, we evaluate performance of the developed blockchain network based on resources (CPU and memory) consumption metrics which are important in planning resources during system deployment. The evaluation findings reveal that, Raft consensus protocol consumes resources more efficiently than Kafka consensus protocol.

Development of a system to detect eye position abnormality based on eye-tracking
Uchida N., Takatuka K., Yamaba H., Mukunoki M., Okazaki N.

In previous research, we developed a method to automate the conventional evaluation of eye misalignment (cover test) and distinguish misaligned eyes from their movements. However, this method had the problem that vertical eye movements were affected by the eyelids and eyelashes, and could not be completely detected. To solve this problem, we have developed another method to recognize abnormalities by observing only the movement near the center of the pupil.

Evaluating the test suite that contains redundant test cases is necessary to ensure the efficiency of the testing and reducing the cost of testing. The principle of redundant test cases on this research is any test cases on a similar path executed with a similar high value of normalized Euclidean distance. The first, the similarity calculated between the test cases and path coverage uses Euclidean distance. The value of the Euclidean distance on the test case with the lowest value of distance indicating highly similar and possibly executing similar lines of code. The normalized Euclidean distance is using to normalize the value from Euclidean distance result. The experiment uses two java programs. Each redundancy score is 0.37 and 0.67, respectively. It means 37% and 67% of the test cases should be avoided because there are inefficiency test cases on the test suite. The research confirms redundant test cases can be identified by Euclidean distance and normalized Euclidean distance to evaluate the test suite.

Ensuring traceability of software deliverables is one of the methods to ensure software quality. RETUSS (Real-time Ensure Traceability between UML and Source-code System) is a tool that saves labor and time, and eliminates mistakes by human handling in ensuring traceability between UML and source code. However, RETUSS is not useful due to its limited scope of application. This paper improves the usefulness of RETUSS by extending the function to ensure real-time traceability between UML sequence diagrams and Java source code on RETUSS.

The natural language includes ambiguous expressions. Vienna Development Method (VDM) is one of methodology on the formal methods to write the specification without ambiguity. Because VDM++ is written by strict grammar, it is difficult to write a VDM++ specification. This research attempts to generate a VDM++ specification automatically from a natural language specification by machine learning. To generate a VDM++ specification, it is necessary to extract words that consist of predicate corresponding to the function and nouns corresponding to variable from the natural language specification. This paper proposes an approach to generate a VDM++ specification based on its grammar from the classified word list. Identifiers are generated from the classified word list, and then the VDM++ specification can be generated by converting them into VDM++ grammar.

Foot-and-mouth disease (FMD) models—analytical models for tracking and analyzing FMD outbreaks—are known as dominant tools for examining the spread of the disease under various conditions and assessing the effectiveness of countermeasures. There has been some remarkable progress in modeling research since the UK epidemic in 2001. Several modeling methods have been introduced, developed, and are still growing. However, in 2010 when a FMD outbreak occurred in the Miyazaki prefecture, a crucial problem reported: Once a regional FMD outbreak occurs, municipal officials in the region must make various day-today decisions throughout this period of vulnerability. The deliverables of FMD modeling research in its current state appear insufficient to support the daily judgments required in such cases. FMD model can be an efficient support tool for prevention decisions. It requires being conversant with modeling and its preconditions. Therefore, most municipal officials with no knowledge or experience found full use of the model difficult. Given this limitation, the authors consider methods and systems to support users of FMD models who must make real-time epidemic-related judgments in the infected areas. We propose a virtual sensor, designated “FMD-VS,” to index FMD virus scattering in conditions where there is once a notion of FMD; and (2) shows how we apply the developed FMD-VS technique during an outbreak. In (1), we show our approach to constructing FMD-VS based on the existing FMD model and offer an analysis and evaluation method to assess its performance. We again present the results produced when the technique applied to 2010 infection data from the Miyazaki Prefecture. For (2), we outline the concept of a method that supports the prevention judgment of municipal officials and show how to use FMD-VS.
