Path planning and obstacle avoidance are two challenging problems in the study of intelligent robots. In this paper, we develop a new method to alleviate these problems based on deep Q-learning with experience replay and heuristic knowledge. In this method, a neural network has been used to resolve the "curse of dimensionality" issue of the Q-table in reinforcement learning. When a robot is walking in an unknown environment, it collects experience data which is used for training a neural network;such a process is called experience *** knowledge helps the robot avoid blind exploration and provides more effective data for training the neural network. The simulation results show that in comparison with the existing methods, our method can converge to an optimal action strategy with less time and can explore a path in an unknown environment with fewer steps and larger average reward.

In recent years, against the backdrop of smart grids, vehicle-to-grid (V2G) interaction has become a hot topic. With the increasing number of new energy vehicles, handling massive amounts of electricity transaction data has become an urgent problem in need of resolution. Ensuring the security of the vast quantities of electricity transaction data has emerged as a significant challenge. Therefore, two data aggregation schemes are proposed in this paper, both supporting batch verification and privacy protection in centralized and distributed scenarios, respectively. Firstly, an improved Paillier cryptosystem is utilized to achieve lightweight encryption in the proposed schemes. In addition, a novel distributed data aggregation structure that combines a large number of geographically distributed fog nodes with centralized cloud servers is introduced. This structure not only meets the requirements of lightweight encryption and resistance against single point failures but also reduces the communication complexity of distributed data aggregation to O(n). According to the security proofs and experimental analysis, it can be demonstrated that both proposed schemes are effective and secure, meeting the lightweight requirements of modern smart grid systems. © 2025 IEEE.

Hybrid MARTE statecharts

Frontiers of Computer science 2013年第1期7卷 95-108页

The specification of modeling and analysis of real-time and embedded systems （MARTE） is an extension of the unified modeling language （UML） in the domain of real-time and embedded systems. Even though MARTE time model offers a support to describe both discrete and dense clocks, the biggest effort has been put so far on the specifi- cation and analysis of discrete MARTE models. To address hybrid real-time and embedded systems, we propose to ex- tend statecharts using both MARTE and the theory of hybrid automata. We call this extension hybrid MARTE statecharts. It provides an improvement over the hybrid automata in that： the logical time variables and the chronometric time vari- ables are unified. The formal syntax and semantics of hybrid MARTE statecharts are given based on labeled transition sys- tems and live transition systems. As a case study, we model the behavior of a train control system with hybrid MARTE statecharts to demonstrate the benefit.

The Clock Constraint Specification Language (CCSL) is a formal polychronous language based on the notion of logical clock. It defines a set of kernel constraints that can represent both asynchronous and synchronous relations. It was originally developed as part of the UML Profile for MARTE to express causal and temporal constraints of Real-time and Embedded Systems. In this paper, we explore the use of CCSL for modeling scheduling requirements and to conduct schedulability analysis. For this purpose, a dedicated scheduling library of CCSL has been built. This library is endowed with a state-based operational semantics, and is applied to solve issues related to schedulability analysis and latency-insensitive design. We establish schedulability categories and latency-insensitiveness property in the context of the semantics, and solve those issues by using model checking techniques.

From message sequence charts to service component model

Message Sequence Charts (MSCs) are a popular visual formalism for documenting system requirements. From MSCs to architecture level model is usually through manual work, which puts the burden on the human and may introduce errors to the design. In this paper, we present a framework for automatically mapping MSCs to service component models from a model-based point of view. The generated models capture service component signatures and language independent dynamic behaviors. We have implemented our framework and demonstrated the benefits via a case study. © 2012 Springer-Verlag.

System's requirements can be specified by textual use cases since their concrete, narrative style of expression makes them very effective for eliciting software requirements. However, use cases are stated in natural languages lacking in formal syntax and semantics, thus have a poor basis for formal reasoning about the system's behavior and properties. It is our attempt to give a solution to solve this issue to some extent. © 2012 Springer-Verlag London Limited.

With the development of web technologies and the increasing size of web sites, the structure of the web application becomes more complicated, and it becomes a difficult task to model and analyze it. Web navigation, which is useful for clarifying requirements and specifying implementation behavior, can be helpful in the analysis of web application. The structure of a web application can be checked based on the web navigation model. In this paper, we present a method to model and check a web application based on web navigation. We first model the web navigation by statechart, and then translate the statechart model to Promela description (the input language of SPIN), meanwhile, the properties to be checked are specified by LTL (Lineal Temporal Logic);finally the web navigation can be checked by SPIN. A case study demonstrates the advantages of our method. © 2012 Springer-Verlag GmbH.

A method to automatically generate test cases from requirements

Advances in Information sciences and Service sciences 2012年第5期4卷 9-20页

作者： Jiang, Mingyue Ding, Zuohua Center of Math Computing and Software Engineering Zhejiang Sci-Tech University Hangzhou Zhejiang 310019 China

The automation of test case generation process can reduce the testing cost. However, the existing models being used by the test case generation techniques are largely manual built by domain expert from system requirements. Thus there is a large gap to bridge between high-level requirements and concrete test cases in order to automate the test generation process. Since textual use cases are easy to describe and understand, they are often used to describe system requirement and are believed to be a good basis for system testing. In this paper, we propose a new approach for automating the generation of system test cases from textual use cases. We build Activity Tables from textual use cases, then construct an Extended Finite State Machine(EFSM) from Activity Tables, finally generate test cases from EFSM. Our objective is to cover the system in terms of statement coverage with those generated tests. A Market Information System(MIS) is employed to demonstrate our approach.
