Metaheuristics are optimization techniques that can be adapted to different problem domains. They are considered general algorithms that have been successful in solving various problems. However, the increase in redundant 'novel' metaheuristics lacking solid validation has become a criticized trend in the research area. In this work, we present a software tool offering interactive development and metaheuristics customization. This software is based on a standard and theoretical framework for analyzing, modifying, and generating metaheuristics. We take advantage of this framework to examine some algorithms recently reported as innovative in the literature and reveal their true nature. Plus, these tools enable rapid prototyping of metaheuristics and allow for static validation experimentation and comparison of algorithms. It helps in the refinement and fine-tuning of the metaheuristics. We present a case study demonstrating the proposed tool's effectiveness, which promises influential scientific contributions and unlocks the potential of metaheuristics. © 2024 IEEE.

This work introduces the software tool Comprehensive Particle Identification (CPID). It is a modular approach to combined PID for future Higgs factories and implemented in the Key4hep framework. Its structure is explained, the current module library laid out and initial performance measures for the ILD detector as an example presented. A basic run of CPID works already as well as the default full-simulation ILD PID reconstruction, but allows for an easy and convenient addition of more PID observables, improving PID performance in future analyses and high-level reconstruction, such as strange tagging. © 2024 Sissa Medialab Srl.

Hybrid agile is one of the recent software engineering process model used by a software engineering team in a software development project. A hybrid agile model is used by software engineering team to meet the requirements of a software project. However, what does the hybrid agile model used by a software engineering team look like? A qualitative study was conducted to answer this question, and a series of interviews were chosen as a data collection instrument. The interview participants are practitioners involved in software projects using hybrid agile. The recorded interviews are transcribed and analysed using thematic analysis. The finding shows that the software engineering team uses the Waterfall model in the planning, design, deployment and maintenance phases, while scrum in the development and testing phases. The results have led to the hybrid agile model presented in this study, which leverages the strengths of each model to ensure the completion of a software project. Future iterations of this study will assess a project's software quality, comparing the proposed model with plan-driven and scrum. © 2024 IEEE.

The importance of roads in the life of almost every modern person is quite huge. One of the key characteristics of the road surface is its quality. To assess the quality of roads, there are many systems, most of which work with a stream of video information. This problem is solved mainly by analyzing images that are obtained from the video stream. To split video into frames, there are special software tools with varying effectiveness. In this research, the average time to retrieve one frame from a video is selected as the main performance indicator. FFMpeg, MoviePy and OpenCV are selected as analyzed programs for splitting videos into frames. The study will help determine the most effective software tool and format for postprocessing (splitting into frames) videos received from any source: a phone camera, drone, etc. The research material is a minute-long video containing a road surface (any other video can be used, it is just example) with a frequency of 25 frames/sec. in 4 formats (avi, mov, mp4, wmv) and 5 resolutions of 16:9 (240p, 320p, 480p, 720p, 1080p) - a total of 20 different videos for each of the selected software tools (total number of experiments are 60). All selected programs have linear dependence on the resolution for each format. However, FFMpeg software tool and wmv format have the lowest absolute time values;FFMpeg also has a significantly better effectiveness compared to MoviePy and OpenCV. © 2024 IEEE.

CASE: A Context-Aware Storage Placement and Retrieval Ecosystem

Emerging cloud-native technologies, such as container-runtime and container-orchestrator offer unprecedented agility in developing and running applications, especially when combined with microservice-style architecture. Several existing 5G-Telecom network products such as element Management System (e-MS), 5G-Core and 5G-Access are being redesigned to fit the microservice paradigm. Cloud environment allows enterprises to scale their application on-demand with minimum cost;however, it is often difficult to use containers without sacrificing many benefits that cloud-native technology offers. The e-MS is characterized to orchestrate 5G network elements (5GNEs) deployed nationwide, and systematically store terabytes of stateful data per second. Containers are characterized to have an ephemeral state, hence 'stateful-ness' aspect of e-MS makes orchestration complex. In this paper, different challenges around stateful storage selection, content placement and content retrieval operations within e-MS microservices are described. To overcome these challenges, to this end, we propose CASE - A Context-Aware Storage placement and retrieval Ecosystem - which enables context-based operations to be intrinsically supported by the underlying e-MS application. Our approach has been designed to maintain the location-independent philosophy of cloud-native by associating context information directly to 5GNE rather than fixed storage entities, thereby ensuring scalability. Through simulation with real data-set obtained from one of the world's largest terrestrial telecom operator, we show that based on such location-independent context information, CASE with e-MS can facilitate high performance despite dynamic 5GNE count agility, stateless e-MS replication and stateful storage scaling, while not posing a significant signaling burden on the cloud environment.

Dual active bridge (DAB) converter has been widely used in distributed power supply, new energy vehicles, energy storage systems, etc. Their modulation strategy is an important research direction. At present, the research on modulation strategy is basically symmetric phase shift, but it is not enough to generalize modulation strategy comprehensively. In this article, an asymmetric phase-shifting (APS) strategy is proposed to control the power flow by simultaneously adjusting the asymmetric duty cycle and the phase-shifting angle. With this modulation scheme, the current stress and cyclic power loss can be reduced by adjusting the modulation ratio of the inductor current waveform. As a result, the light-load efficiency can be improved compared with the conventional symmetric modulation scheme. The power characteristic, current stress, soft switching characteristic, and backflow power of this modulation strategy are analyzed and calculated comprehensively. Then, based on this asymmetric strategy, a hybrid modulation strategy that can achieve ZVS over the entire power range with low current stress, low return power, and minimum rms current at light load is proposed. Finally, a 100-50 V/300 W prototype is built to verify the analysis.

mpsym: Improving Design-Space Exploration of Clustered Manycores With Arbitrary Topologies

With growing numbers of cores, the memory subsystem of manycore architectures increases in complexity. Many modern multicores are designed in a hierarchical fashion, with multiple clusters of processing elements. However, most algorithms for design-space exploration (DSE) of resource allocation in multicores do not consider these complex topologies, which results in poor scaling, or worse, nonfunctioning algorithms. In this article, we present mpsym, a C++ library designed to alleviate this problem in an algorithm-agnostic fashion. Using methods from the computational group theory, we present domain-specific algorithms to improve DSE in hierarchical architecture topologies. We evaluate mpsym on multiple DSE algorithms from the literature. Without modifying the algorithm, our methods improve the execution time by a factor up to 8.6 x on the embedded system synthesis benchmark suite benchmark suite for complex, clustered architecture topologies. Similarly, by pruning the design space, our methods consistently improve the result of the exploration. In particular, the results from a simulated annealing heuristic on the Kalray MPPA3 Coolidge topology are over 30x better on average, while requiring less time to explore.

The article explores the potential for exchanging information between software tools using the KNIME program. It provides recommendations on utilizing data preprocessing models, methods, and algorithms for data sharing, and offers examples to illustrate these concepts. The article also discusses the capabilities of KNIME for exchanging information between software tools without the need for coding, such as analyzing and sharing data between databases and making predictions based on the data. The article specifically addresses the issue of geo-location of scooters in use in smart cities and the distribution of scooters over a certain period of time. This includes the number of scooters in use and idle at different times of the day, as well as demand data and real data obtained from statistical systems based on weather data. The article also discusses how KNIME can be used to solve regression problems and predict the daily distribution of scooter usage for each station. KNIME is a powerful program that utilizes intelligent technologies for data interoperability between software tools, making it an effective tool for solving forecasting problems and integrating data. © 2024 IEEE.

Recent studies show that requirements analysts struggle with interpreting the LGPD to obtain privacy requirements. In this paper, we propose a method to transform LGPD's legal requirements into a software requirement patterns catalogue. Reusing requirements as patterns can be a viable alternative to assist professionals since the LGPD's legal determinations are recurrent in different software projects. A preliminary evaluation of our patterns catalogue suggests the method's effectiveness. © 2024 27th Ibero-American Conference on software engineering, CIbSE 2024. All rights reserved.
