BACKGROUND: Continuous Test-Driven Development (CTDD) is, proposed by the authors, enhancement of the well-established Test-Driven Development (TDD) agile software development and design practice. CTDD combines TDD with continuous testing (CT) that essentially perform background testing. The idea is to eliminate the need to execute tests manually by a TDD-inspired developer. OBJECTIVE: The objective is to compare the efficiency of CTDD vs TDD measured by the red-to-green time (RTG time), i.e., time from the moment when the project is rendered not compiling or any of the tests is failing, up until the moment when the project compiles and all the tests are passing. We consider the RTG time to be a possible measurement of efficiency because the shorter the RTG time, the quicker the developer is advancing to the next phase of the TDD cycle. METHOD: We perform single case and small-n experiments in industrial settings presenting how our idea of Agile Experimentation materialise in practice. We analyse professional developers in a real-world software development project employing ***. We extend the contribution presented in our earlier paper by: 1) performing additional experimental evaluation of CTDD and thus collecting additional empirical evidence, 2) giving an extended, detailed example how to use and analyse both a single case and small-n experimental designs to evaluate a new practice (CTDD) in industrial settings taking into account natural constraints one may observe (e.g., a limited number of developers available for research purposes) and presenting how to reach more reliable conclusions using effect size measures, especially PEM and PAND which are more appropriate when data are not normally distributed or there is a large variation between or within phases. RESULTS: We observed reduced variance and trimmed means of the RTG time in CTDD in comparison to TDD. Various effect size measures (including ES, d-index, PEM, and PAND) indicate small, albeit non-

This paper presents a tight small-gain theorem for networks composed of infinitely many finite-dimensional subsystems. Assuming that each subsystem is exponentially input-to-state stable, we show that if the gain operator, collecting all the information about the internal Lyapunov gains, has a spectral radius less than one, the overall infinite network is exponentially input-to-state stable. We illustrate the effectiveness of our result by applying it to traffic networks.

Al. Prof. S. Kaliskiego 7 85-796 Bydgoszcz Poland

In this paper, we introduce a novel Binary Directional Shape (BDS) descriptor for efficient object shape classification. The BDS descriptor is designed to operate in real-time environments, balancing computational efficiency with high classification accuracy. The descriptor works by resizing input images, thresholding them into binary representations, and analyzing them along multiple predefined directions. Configurable parameters such as image size, number of directions, and step size allow for customization based on application needs. Through extensive experiments, we explore the effects of image resolution on shape classification, demonstrating how aliasing and resolution loss can impact performance. Our results show that while higher resolutions improve accuracy, challenges such as rotation variance and aliasing persist. The BDS descriptor outperforms traditional feature-based methods, providing superior classification results even in the presence of these challenges. This work demonstrates the value of directional information in shape recognition and sets the stage for future optimizations and applications.

The European eSafety initiative aims to improve the safety and efficiency of road transport. The main element of eSafety is the pan-European eCall project—an in-vehicle system which idea is to inform about road collisions or serious accidents. As estimated by the European Commission, the implemented system will reduce services’ response time by 40%. This will save 2,500 people a year. In 2015, the European Parliament adopted the legislation that from the end of March 2018 all new cars from the EU should be equipped with the eCall system. The limitation of this idea is that only small part of cars driven in UE are brand new (about 3.7% brand new cars were sold in 2015). This paper presents the first concept of an onboard eCall device which can be installed at the owners’ request in used vehicles. The proposed system will be able to detect a road accident, indicate the number of vehicle’s occupants, report their vital functions, and send that information to dedicated emergency services via duplex communication channel. © Springer Nature Singapore Pte Ltd. 2019.

Voting is the important procedure in different countries worldwide and is essential to any consensus-dependent society. Especially in the context of COVID pandemic where people stays home, such systems are very relevant today. Elections can happen for different reasons, involving choosing leaders, finishing political problems, choosing a substantial government, etc. The phenomenal using of Information Technology in the process of election is quickly earning momentum. This growth in voting systems indicated to as evoting comes with more benefits than the voting system based on paper. While there are many efforts in different parts of world regarding implementations and trials for electronic voting, there are not many researches regarding this in Asia Minor, especially Iraq. It can be noted that Iraq has several regions with difficult access and where sometime it is difficult to collect votes in the traditional way because of access reasons and post-war conditions. We want to fill this gap through the research presented in this paper. In this paper we describe an application for m-voting targeting the specific conditions of Iraq in the COVID situation. In the current society, the application of which we are talking about, can also be seen as a significant help for a numerous amount of countries during the pandemic of COVID-19. The application is based on Mobile technology. We choose mobile technology motivated by the fact that although people do not have computers, almost everyone has a mobile phone in Iraq. Moreover, the usefulness of mobiles can represent a proper way for people with disabilities to execute their legal right to vote for the future of their country.

Stability analysis of gradient-based distributed formation control with heterogeneous sensing mechanism: Two and three robot case

This paper focuses on the stability analysis of a formation shape displayed by a team of mobile robots that uses heterogeneous sensing mechanism. Depending on the convenience and reliability of the local information, each robot utilizes the popular gradient-based control law which, in this paper, is either the distance-based or the bearing-only formation control. For the two and three robot case, we show that the use of heterogeneous gradient-based control laws can give rise to an undesired invariant set where a distorted formation shape is moving at a constant velocity. The (in)stability of such an invariant set is dependent on the specified distance and bearing constraints. For the two robot case, we prove almost global stability of the desired equilibrium set while for the three robot case, we guarantee local asymptotic stability for the correct formation shape. We also derive conditions for the three robot case in which the undesired invariant set is locally attractive. Numerical simulations are presented for illustrating the theoretical results in the three robot *** Codes 34H05, 70E60, 93C10, 93C85 © 2020, CC-BY-NC-SA.

Angle-Constrained Formation control for Circular Mobile Robots

arXiv

arXiv 2020年

— In this letter, we investigate the formation control problem of mobile robots moving in the plane where, instead of assuming robots to be simple points, each robot is assumed to have the form of a disk with equal radius. Based on interior angle measurements of the neighboring robots’ disk, which can be obtained from low-cost vision sensors, we propose a gradient-based distributed control law and show the exponential convergence property of the associated error system. By construction, the proposed control law has the appealing property of ensuring collision avoidance between neighboring robots. We also present simulation results for a team of four circular mobile robots forming a rectangular *** Codes 34H05, 70E60, 93C10, 93C85 Copyright © 2020, The Authors. All rights reserved.

A Review of Tracking, Prediction and Decision Making Methods for Autonomous Driving

arXiv

arXiv 2019年

作者： Leon, Florin Gavrilescu, Marius "Gheorghe Asachi" Technical University of Iaşi Romania Faculty of Automatic Control and Computer Engineering

This literature review focuses on three important aspects of an autonomous car system: tracking (assessing the identity of the actors such as cars, pedestrians or obstacles in a sequence of observations), prediction (predicting the future motion of surrounding vehicles in order to navigate through various traffic scenarios) and decision making (analyzing the available actions of the ego car and their consequences to the entire driving context). For tracking and prediction, approaches based on (deep) neural networks and other, especially stochastic techniques, are reported. For decision making, deep reinforcement learning algorithms are presented, together with methods used to explore different alternative actions, such as Monte Carlo Tree Search.
