Considering the complexity and variability of the actual traffic environment, aiming at the influence of driving styles on the optimal control of hybrid electric vehicles (HEVs) energy management, this paper proposes a speed planning and energy management strategy (EMS) considering driving style recognition in mixed driving scenarios under the framework of model predictive control (MPC). the proposed strategy uses principal component analysis (PCA) to reduce the dimension of the characteristic parameters and fuzzy C-means (FCM) methods to cluster driving styles. Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) are used to obtain information on the preceding vehicle and traffic lights to classify the hybrid driving scenario. In the different scenarios, the objective function considering traffic safety is constructed to plan the host vehicle’s speed based on the speed prediction of the preceding vehicle. A sequential quadratic programming optimization algorithm (SQP) distributes engine and motor power. Simulation results show that the proposed EMS can achieve good fuel economy under the premise of driving safety.

Modern software codebases are frequently large, heterogeneous, and constantly evolving. the languages and tools for software construction, including code builds and configuration management, have not been well-studied. Developers are often faced with using 1) older tools (like make) that do not scale well, 2) custom build scripts that tend to be fragile, or 3) proprietary tools that are not portable. In this paper, we study the build issue as a domain-specific programming problem. there are a number of challenges that are unique to the domain of build systems. We argue that a central goal is compositionality-that is, it should be possible to specify a software component in isolation and add it to a project with an assurance that the global specification will not be compromised. the next important goal is to cover the full range of complexity-from allowing very concise specifications for the most common cases to providing the flexibility to encompass projects with unusual needs. Dependency analysis, which is a prerequisite for incremental builds, must be automated in order to achieve compositionality an reliability;it also spans the full range of complexity. We develop a language for describing software builds and configuration. We also develop an implementation (called Omake), that addresses all the above challenges efficiently and portably. It also provides a number of features that help streamline the edit/compile development cycle. OMake is freely available under the GNU General Public License, and is actively being used in several large projects.

Unmanned surface vehicle plays an important role in the implementation of ocean tasks based on its autonomous navigation ability, flexibility, cost-efficiency, and strong adaptability. As the core component of the autonomous navigation capability of USV, path planning is an essential guarantee for safe voyage in an unknown ocean environment. In this paper, a time-efficient USV path planning algorithm based on weighted dynamic programming (WDP) is proposed. the proposed algorithm first discrete the continuous area using direction oriented grid structure method, and all the grids are potential path selection candidates. then, considering the ocean environment factors of the target area, the weighted dynamic planning algorithm is proposed for USV path planning, which aims at generating a safe and time-efficient path. At the same time, the virtual potential field method is applied for the need of sudden dangerous situations for obstacles avoidance. the simulation results show that the weighted dynamic programming algorithm is able to generate a time-efficient path and verified the correctness and superiority of the proposed algorithm.

Coal mining and iron ore mining are the main forms of current mining engineering, and the mining of these two minerals is greatly affected by the geological conditions of the mine and the surrounding environment. therefore, it is necessary to conduct a comprehensive analysis of all influencing factors of mining to assist in mining engineering decision-making, and currently there is a lack of corresponding technical methods to meet this demand. In response to this issue, this article proposes the construction of a digital twin model oriented toward the environment of mines and surrounding areas, providing a complete description of the panoramic appearance of mines to meet the needs of mining engineering construction and production. Utilize various sensors such as drones and cameras to obtain full data of the mine and its surrounding areas, and define standardized collection frequencies to ensure data consistency and real-time in the digital twin model. then, using algorithmic logic such as big data analysis and artificial intelligence, the multi-source data in the model is fused and analyzed to meet the production and construction management needs of mining engineering. By utilizing the logical algorithm analysis results in the digital twin model of mines, it is possible to comprehensively analyze the cross-sectional view, component analysis, and risk warning of mines, obtain auxiliary decision-making basis, and reduce safety risks in mining engineering, thereby improving economic benefits. Finally, a digital twin model for mining engineering is designed and implemented through computer programming, providing auxiliary decision-making tool support for the development and operation of mining business. © the Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

As a branch of the simulation field, network simulation technology is increasingly becoming a powerful tool for analysis, research and design. In recent years, the Network Simulator 3 (NS3) simulator has made significant progress with its rich network component object library and relatively perfect bottom-level programming modelling. However, most of the current research on NS3 is based on the existing algorithms for differentiation and comparative analysis, lacking the open-source platform design, the training means of satellite communication system simulation and research on the overall platform building framework based on NS3. this article proposes a complete congestion-control open-source platform construction strategy for Low Earth Orbit (LEO) satellite. the top-level building process of the satellite simulation platform is introduced in detail, and the bottom layer is modularized into four parts to achieve. the NS3 top-level frame realization process and the bottom-level network element unit are modularized to build a complete satellite model simulation platform. It provides some ideas for promoting the development of satellite routing algorithm simulation experiments.

While dynamic code evolution in object-oriented systems is an important feature supported by dynamic languages, there is currently only limited support for dynamic code evolution in high-performance, state-of-the-art runtime systems for statically typed languages, such as the Java Virtual Machine. In this tool demonstration, we present the Dynamic Code Evolution VM, which is based on a recent version of Oracle's state-of-the-art Java HotSpot (TM) VM and allows unlimited changes to loaded classes at runtime. Based on the Dynamic Code Evolution VM, we developed an enhanced version of the Mantisse GUI builder (which is part of the NetBeans IDE) that allows adding GUI components without restarting the application under development. Furthermore, we redesigned the dynamic AOP framework HotWave to take advantage of the enhanced dynamic code evolution capabilities. the new version, HotWave2, now supports most AspectJ constructs, including around() advice and static cross-cutting. We will demonstrate both the enhanced Mantisse GUI builder as well as HotWave2, weaving several aspects for dynamic analysis in sizable applications at runtime.

A process route recommendation engine for aviation structural components based on ANN-LCS algorithm is introduced. By processing the machining process knowledge of aviation structural components, defining their basic information and process route data, and then constructing and training an ANN (Artificial Neural Network) to classify parts. Based on part classification, the LCS (Longest Common Substring) algorithm based on dynamic programming is used to generate process routes. through the testing of process route recommendation examples, the results show that this method can effectively obtain and select feasible process routes in the process design stage.

Delayed evaluation, self-optimising software components as a programming model 8th

We argue that delayed-evaluation, self-optimising scientific software components, which dynamically change their behaviour according to their calling context at runtime offer a possible way of bridging the apparent conflict between the quality of scientific software and its performance. Rather than equipping scientific software components with a performance interface which allows the caller to supply the context information that is lost when building abstract software components, we propose to recapture this lost context information at runtime. this paper is accompanied by a public release of a parallel linear algebra library with both C and C++ language interfaces which implements this proposal. We demonstrate the usability of this library by showing that it can be used to supply linear algebra component functionality to an existing external software package. We give preliminary performance figures and discuss avenues for future work. © Springer-Verlag Berlin Heidelberg 2002.

In the context of a highly interconnected energy landscape, coordinated cyber-physical attacks on integrated energy systems can cause significant damage and trigger considerable economic impacts. In order to ensure the robustness and uninterrupted function of such systems, the interaction between information and physical matrix is analyzed based on the inherent coupling mechanism unique to the integrated energy information-physical framework. After the basic analysis, a threelayer dynamic game model is designed using the strategy of game theory. the model is transformed into a mixed integer linear programming formula, load loss is selected as the vulnerability assessment index, and defense resources are effectively allocated to each component of the integrated energy system. Finally, an IEEE-39-node grid is coupled to an 11-node gas distribution network. Research and analysis, the proposed model and its related methods have been verified.

In external-beam radiotherapy (RT), high-energy radiation beams are delivered by a linear accelerator in a series of irradiation sessions undertaken over multiple days. In this work, we consider the problem of scheduling and sequencing RT sessions considering time window preferences given by patients for the starting time of their appointments. Most studies in the literature focus on assigning patients to linacs and days, neglecting the sequencing component, and existing sequencing algorithms are only able to solve the problem using approximation methods due to the intractability of the formulated models. We propose a mixed-integer linear programming model and test it using data from a large Dutch RT center. Results show that the problem can be solved in reasonable computation time for real-world size instances using our model. © 2020, Springer Nature Switzerland AG.
