    Opis:
    Testing is an indispensable part of the software development life cycle. It is performed to improve the performance, quality and reliability of the software. Various types of testing such as functional testing and structural testing are performed on software to uncover the faults caused by an incorrect code, interaction of input parameters, etc. One of the major factors in deciding the quality of testing is the design of relevant test cases which is crucial for the success of testing. In this paper we concentrate on generating test cases to uncover faults caused by the interaction of input parameters. It is advisable to perform thorough testing but the number of test cases grows exponentially with the increase in the number of input parameters, which makes exhaustive testing of interaction of input parameters imprudent. An alternative to exhaustive testing is combinatorial interaction testing (CIT) which requires that every t-way interaction of input parameters be covered by at least one test case. Here, we present a novel strategy ABC-CAG (Artificial Bee Colony-Covering Array Generator) based on the Artificial Bee Colony (ABC) algorithm to generate covering an array and a mixed covering array for pair-wise testing. The proposed ABC-CAG strategy is implemented in a tool and experiments are conducted on various benchmark problems to evaluate the efficacy of the proposed approach. Experimental results show that ABC-CAG generates better/comparable results as compared to the existing state-of-the-art algorithms.

    Opis:
    The limitation of time and budget usually prohibits exhaustive testing of interactions between components in a component based software system. Combinatorial testing is a software testing technique that can be used to detect faults in a component based software system caused by the interactions of components in an effective and efficient way. Most of the research in the field of combinatorial testing till now has focused on the construction of optimal covering array (CA) of fixed strength t which covers all t-way interactions among components. The size of CA increases with the increase in strength of testing t, which further increases the cost of testing. However, not all components require higher strength interaction testing. Hence, in a system with k components a technique is required to construct CA of fixed strength t which covers all t-way interactions among k components and all ti-way (where ti > t) interactions between a subset of k components. This is achieved using the variable strength covering array (VSCA). In this paper we propose a greedy based genetic algorithm (GA) to generate optimal VSCA. Experiments are conducted on several benchmark configurations to evaluate the effectiveness of the proposed approach.

    Opis:
    Background. Free radicals play a key role in the development of several pathological conditions. Therefore, antioxidants (AOs) are the first line of defense against free radical damage and are critical for maintaining optimum health and wellbeing. Objectives: To assess the perception of dental practitioners regarding use of antioxidants in oral health. Method. A cross-sectional questionnaire study was conducted among 296 dental practitioners in Tricity (Chandigarh, Mohali, Panchkula, India). A self-structured close-ended questionnaire was used to assess the perception of dentists regarding the use of antioxidants in their patients. It consisted of 12 questions with dichotomous response and five point likert scale ranging from strongly agree to strongly disagree. Descriptive statistics were used to summarize the data, followed by the Chi-square test to check significant differences between the responses. Correlation between responses were analysed through the Spearman’s rank correlation. Statistical analysis was done using Statistical Package for Social Sciences version 20 (Illinois, Chicago, USA). Results. A statistically significant difference was observed between genders, with females 181 (61%) having more knowledge than males 115 (39%) regarding the use of antioxidants in their clinical practice. It has been found that dental professionals in academics prescribes more antioxidants to their patients than the private practitioners. Postgraduates 76 (77.6%) had a higher level of knowledge than graduates 86 (43%). Conclusions. Knowledge about antioxidants should be highlighted in the health sciences curriculum. It is recommended to expand the use of antioxidants in oral health to bring down the burden of chronic diseases like periodontitis and catastrophic diseases like precancerous lesions and oral cancer.

    Opis:
    The agri-food sector contributes significantly to economic and social advancements globally despite numerous challenges such as food safety and security, demand and supply gaps, product quality, traceability, etc. Digital technologies offer effective and sustainable ways to these challenges through reduced human interference and improved data-accuracy. Innovations led by digital transformations in the agri-food supply chains (AFSCs) are the main aim of 'Agri-Food 4.0'. This brings significant transformations in the agri-food sector by reducing food wastage, real-time product monitoring, reducing scalability issues, etc. This paper presents a systematic review of the innovations in the agri-food for digital technologies such as internet-of-things, artificial intelligence, big data, RFID, robotics, blockchain technology, etc. The employment of these technologies from the ‘farm to fork’ along AFSC emphasizes a review of 159 articles solicited from different sources. This paper also highlights digitization in developing smart, sensible, and sustainable agri-food supply chain systems.
