Although cloud computing resources can help scientific workflow applications, several algorithms face the problem of meeting the user’s deadline while minimising the cost of workflow execution. In the cloud, selecting the appropriate type and the exact number of VMs is a major challenge for scheduling algorithms, as tasks in workflow applications are distributed very differently. Depending on workflow requirements, algorithms need to decide when to provision or de-provision VMs. Therefore, this paper presents an algorithm for effectively selecting and allocating resources. Based on the workflow structure, it decides the type and number of VMs to use and when to lease and release them. For some structures, our proposed algorithm uses the initial rented VMs to schedule all tasks of the same workflow to minimise data transfer costs. We evaluate the performance of our algorithm by simulating it with synthetic workflows derived from real scientific workflows with different structures. Our algorithm is compared with Dyna and CGA approaches in terms of meeting deadlines and execution costs. The experimental results show that the proposed algorithm met all the deadline factors of each workflow, while the CGA and Dyna algorithms met 25% and 50%, respectively, of all the deadline factors of all workflows. The results also show that the proposed algorithm provides more cost-efficient schedules than CGA and Dyna.}, year = {2024}, eissn = {2156-5570}, pages = {792-802}, orcid-numbers = {Kecskeméti, Gábor/0000-0001-5716-8857} } @CONFERENCE{MTMT:34654257, title = {Analyzing and Designing an Optimization System for In-Plant Complex Production Based on Industry 4.0}, url = {https://m2.mtmt.hu/api/publication/34654257}, author = {Akkad, Mohammad Zaher and Bányai, Tamás}, booktitle = {9th International Conference on Advanced Engineering and Technology (ICAET)}, doi = {10.4028/p-Es6Xrb}, unique-id = {34654257}, abstract = {Industry 4.0 symbolizes various applications and technologies that have many possible positive effects within the industrial field.

Recent research focuses on improving quality with advanced neural networks and machine learning techniques. However, selecting the appropriate target sentences and concepts remains challenging in AQG systems. To address this problem, the authors created a novel system that combined sentence structure analysis, dependency parsing approach, and named entity recognition techniques to select the relevant target words from the given sentence. The main goal of this paper is to develop an AQG system using syntactic and semantic sentence structure analysis. Evaluation using manual and automatic metrics shows good performance on simple and short sentences, with an overall score of 3.67 out of 5.0. As the field of AQG continues to evolve rapidly, future research should focus on developing more advanced models that can generate a wider range of questions, especially for complex sentence structures.}, year = {2024}, eissn = {2502-4760}, pages = {1108-1115} } @mastersthesis{MTMT:34498054, title = {Utilizing Data-Balancing Techniques to Improve AI-Based Prediction of Software Bugs and Code Smells}, url = {https://m2.mtmt.hu/api/publication/34498054}, author = {Alnor Adam Khleel, Nasraldeen}, doi = {10.14750/ME.2024.012}, unique-id = {34498054}, year = {2024} }
