Software defect prediction(SDP), which predicts defective code areas, including files, code blocks, code lines, etc. It can help developers or testers in allocating test resources before the testing phase. Software defect number prediction(SDNP) is an important research direction of SDP. Previous studies mostly used regression-based methods or different neural networks to mine the semantic features contained in AST, but the way to represent code was relatively simple. In this article, we propose a framework for representing the semantic features in terms of sequences of nodes with a double sequence structure, by analyzing the ASTs and the changes in the code blocks between adjacent version. In addition, to combine statistical metric information, we also propose a model that dynamically determines the ratio of semantic features to traditional metric features during model training by using the gated fusion mechanism to perform SDNP. In the experimental part, we select 10 open source Java projects as training and test sets, and conduct a lot of comparative experiments. The experimental results demonstrate the superiority of our proposed method compared to the baseline approach.

Microservices Architectures (MSA) have found large adoption in companies delivering online services, often in conjunction with agile development practices. Microservices are distributed, independent and polyglot entities – all features favouring black-box testing. However, for real-scale MSA, a pure black-box strategy may not be able to exercise the system to properly cover the interactions involving internal microservices.We propose a grey-box strategy (MACROHIVE) for automated testing and monitoring of (internal) microservices interactions. It uses combinatorial testing to generate valid and invalid tests from microservices specification. Tests execution and monitoring are automated by a service mesh infrastructure. MACROHIVE runs the tests and traces the interactions among microservices, to report about internal coverage and failing behaviour.MACROHIVE is experimented on TrainTicket, an open-source MSA benchmark. It performs comparably to state-of-the-art techniques in terms of edge-level coverage, but exposes internal failures undetected by black-box testing, gives detailed internal coverage information, and requires fewer tests.

Smart contracts are applications running on the blockchain which control many virtual currencies. Since smart contracts are composed of code, they inevitably have defects. In recent years, many smart contract defects have caused lots of economic losses and harmful impacts. A contract that has defects may have some errors that cause unwanted results. As smart contracts cannot be modified once deployed, it is necessary to ensure that they are free from defects. In this paper, we focus on eleven defects of smart contracts and construct a deep learning-based model to detect these contract defects more accurately. Our model regards the smart contract’s operation codes as a sequential sentence and uses an Attention-based bidirectional long short term memory (BiLSTM-Attention) model to find smart contract defects. We evaluate our model’s and other models’ performance on 45622 real-world smart contracts. The experimental results show that our model can achieve higher accuracy (95.40%) and F1-score (95.38%). In addition, our model is highly efficient and can quickly detect large numbers of contracts.

Defect detection aims to locate the accurate position of defects in images, which is of great significance to quality inspection in the industrial product manufacturing. Currently, many defect detection methods rely on deep neural networks to extract features. Although the accuracy of these methods is relatively high, it is computationally intensive, making the methods difficult to deploy in resource-limited edge devices. In order to solve these problems, a lightweight defect detection model for the industrial edge environment is proposed, termed the efficient defect detection network (EDDNet). EfficientNet-B0 is used as the feature extraction backbone, extracting feature maps from feature layers of different depths of the network and fusing multilevel features by multilevel feature fusion (MFF). To obtain more information, we redesign the attention mechanism in MBConv blocks, taking the encoding space (ES) attention mechanism as a new module, which solves the problem that the defective image spatial information is ignored. The experimental results on the NEU-DET and DAGM2007 datasets and PCB defect datasets demonstrate the effectiveness of the proposed EDDNet and its possibility for application in industrial edge device.

Due to the proliferation of machine learning in various domains and applications, Machine Learning Operations (MLOps) was created to improve efficiency and adaptability by automating and operationalizing ML products. Because many machine learning application domains demand high levels of assurance, security has become a top priority and necessity to be involved at the beginning of ML system design. To provide theoretical guidance, we first introduce the Secure Machine Learning Operations (SecMLOps) paradigm, which extends MLOps with security considerations. We use the People, Processes, Technology, Governance and Compliance (PPTGC) framework to conceptualize SecMLOps, and to discuss challenges in adopting SecMLOps in practice. Since ML systems are often multi-concerned, analysis on how the adoption of SecMLOps impacts other system qualities, such as fairness, explainability, reliability, safety, and sustainability are provided. This paper aims to provide guidance and a research roadmap for ML researchers and organizational-level practitioners towards secure, reliable, and trustworthy MLOps.

Proof of Work (PoW) is the most widely used consensus protocol. However, due to the hash rate competition mechanism, longest chain principle, and transaction fee mechanism of the PoW consensus protocol, malicious nodes can launch attacks to obtain more relative revenue than honest mining, which will discourage honest miners from packing transactions into blocks and verifying blocks. As a result, the speed of the nodes reaching consensus in the network is slowed down, or even consensus cannot be reached, which ultimately affects the security of the PoW consensus protocol.In this paper, the Markov Decision Process (MDP) is used to simulate the whale attack launched by malicious nodes, and evaluate the capability of PoW consensus protocol against the whale attack. The experimental results show that the PoW consensus protocol is secure in the Bitcoin network when the transaction fee is set in the range of 0.002-0.3 block rewards and the transaction volume should not exceed 21.09 block rewards. In addition, the PoW consensus protocol will be more secure with the adjustment of parameters such as the number of block confirmations, block generation interval and block size.

Efficient and effective object detection is a key problem in Computer Vision. Numerous object detection algorithms have been developed, whose aim is to achieve two conflicting goals, namely accuracy and efficiency, while being executed in real-time with high robustness. Many of these algorithms must run for an extended period of time, i.e., in video surveillance or in self-driving cars – a working condition that make them subject to the risk of software aging.In this work, we focus on evaluating several object detection algorithms to understand if and to what extent they are affected by software aging. A measurement-based aging approach was adopted, with a series of long-running tests and subsequent data analysis. The results report significant trends of performance degradation, sometimes leading to aging-related failures, as well as memory consumption trends, which turned out to be the main issue across all the experiments.

The damage or destruction of Critical Infrastructures (CIs) affect societies’ sustainable functioning. Therefore, it is crucial to have effective methods to assess the risk and resilience of CIs. Failure Mode and Effects Analysis (FMEA) and Failure Mode Effects and Criticality Analysis (FMECA) are two approaches to risk assessment and criticality analysis. However, these approaches are complex to apply to intricate CIs and associated Cyber-Physical Systems (CPS). We provide a top-down strategy, starting from a high abstraction level of the system and progressing to cover the functional elements of the infrastructures. This approach develops from FMECA but estimates risks and focuses on assessing resilience. We applied the proposed technique to a real-world CI, predicting how possible improvement scenarios may influence the overall system resilience. The results show the effectiveness of our approach in benchmarking the CI resilience, providing a cost-effective way to evaluate plausible alternatives concerning the improvement of preventive measures.

Graphical User Interface (GUI) has become one of the most effective human-computer communication medium today. The quality of GUI is essential to the success of apps, especially for mobile apps. Developers not only have to understand the interaction of various components, but also follow the principles of design and implementation. It is helpful for developers to understand the challenges via analyzing the questions and answers (Q&A) on GUI development. However, there is no large-scale study on the GUI development posts on Stack Overflow. In this paper, we conduct an exploratory study on 23,741 posts related to GUI development on Stack Overflow. We first extract 20 topics related to GUI development using topic modeling. After manually classifying these GUI topics into 5 categories, we further quantitatively analyze the popularity and difficulty of GUI topics, the correlation between these two aspects, and qualitatively analyze the distribution of question types in posts. Finally, we have some interesting findings. These findings contain that the topic "tool selection" is the most popular topic, the topic "thread" has the highest percentage of unaccepted answers, and the topic "client/server" answer takes the longest time to be accepted. In addition, we discuss about possible inspirations of our research to GUI development stakeholders.

As a newly proposed computational paradigm of membrane computing, cP systems are used to solve several NP-complete and PSPACE-complete problems in linear or sub-linear time theoretically. Most cP systems proposed in previous studies lack of automated verification support. In this paper, we present cPV, the first software implementation for cP system simulation and verification. cPV offers multiple features, which include modelling, simulation, automated verification of properties such as absence of deadlock, confluence, termination, determinism, and goal reachability. As an extensible framework, modules in cPV are loosely coupled, where new verification algorithms, reduction techniques, and property specifications can be easily extended. To evaluate cPV, we constructed two benchmark datasets that cover several important aspects of cP systems. The experimental results demonstrated effective automatic verification support to the membrane computing problem domain.
