In the field of high-performance computing, some application scenarios make extensive use of bit manipulation. RISC-V foundation issues B extension to reduce the number of instructions during the static compilation. But this extension does not cover the more frequent operations fully. Instruction fusion technology can fuse multiple instructions into one instruction at the decode stage to dynamically reduce the number of instructions. Therefore, this technology can supplement RISC-V B extension uncovered instruction, enhancing the processor’s capabilities for bit manipulation. This paper implements the RISC-V B extension 1.0 version on the Xiangshan processor. For accelerating more bit manipulation, we profiled general benchmarks by the simulator, proposed ten new instructions fusion targets, and implemented a fusion decode unit. Finally, we use Coremark and SPEC CPU 2006 integer to evaluate the performance. The Coremark results show that dynamic instructions reduce by 18.14%, and the performance improves by 12.09%. © 2022 SPIE.

Security certification assesses the security posture of a software system to verify its compliance with diverse, pre-specified security controls identified by guidelines from NIST and the US Department of Defense. Service-oriented architectures (SOA) are difficult to certify because they require compliance verification over a mix of local, global, and interaction criteria dictated by the policies of the participating services and SOA governance. Web services further contribute to this difficulty because they lack direct methods to express security controls. Besides being understandable, the method of expression should indicate potential problems complying with chosen services. This paper presents a method for configuring of web service standards to enforce security requirements on service interaction specification documents within a SOA. The outcome serves as a mechanism to direct the population of constraints derived from security controls within standards specification documents, such as WS-Policy. We focus on security controls for auditing and how these can be enforced in an SOA. We introduce a reusable architecture to notate the comparison of security controls across services.

Comfortable temperature is an important requirement of building control. In order to optimize the intelligent building system, efficiently adjust and control the HVAC system, bring users more comfortable living space, and optimize the HVAC terminal equipment, it is necessary to communicate with the controller to obtain real-time data. However, the traditional way of using the controller is mostly adjusted on the human-machine interface (HMI), which cannot be tested uniformly for different controllers. At present, different controllers have different register addresses and the program is limited to obtaining the data of a specific controller. Different controllers cannot share a set of programs. In addition, modbus has a variety of communication modes. If the communication mode changes, the code needs to be changed and redeveloped. Most of the programming cannot make modbus universal. In order to solve the above problems, this paper focuses on several ways of communication and connection between LabVIEW and Modbus. It mainly proposes a configurable Modbus communication mechanism based on LabVIEW, the Modbus protocol is made universal. The program obtains the configuration parameters of different Modbus communication modes and the parts of different controllers through the configuration file, so as to realize the code scalability and compatibility. Therefore, the controller supporting Modbus protocol can communicate in real time as long as the configuration is modified. This method can be applied to the industrial controller supporting modbus and can effectively solve the problem of communication barriers between the configuration software LabVIEW and different controllers. © 2021 IEEE.

Dynamic, service-based systems offer powerful resources for knowledge and information processing in a crisis situation. These systems need efficient strategies to integrate diverse services under the stress of an emergency to capture, organize, and disseminate appropriate information. These strategies require a combination of service discovery, 'mashing', and orchestration given workflow task templates that can be instantiated and deployed on demand. In this paper, we introduce the Δ-Federation reference architecture for on-demand emergency management systems (ODEMS). The Δ-Federation provides the foundation for incorporating these strategies that consider type, availability, and requirements of services as historically understood by users in similar crisis events.

A spatial proximity based spontaneous interaction approach for "shared nothing" peer-to-peer systems is proposed. Mobile peers that come spatially close to each other wirelessly exchange self describing profiles encoded in an XML dialect. Each peer individually conducts a similarity analysis of the semistructured data contained in the received profile, and, in case of the similarity exceeding a predifined threshold, notifies an application to start executing. Profiles are organized hierarchically, allowing for an efficient interaction check based on peer roles in the first step, and a more detailed analysis of peer preferences in the second step. A novel context-aware profile description language (PPDL) has been developed, expressing peer preferences with respect to the particular situation (like time, geoposition, owner, environmental conditions, etc.) in which the interaction among peers is attempted. The context of a peer is modelled symbolically within its profile, so that sensors can verify the actual context and use the context specific interpretation of the profile prior to similarity analysis. A fully functional software framework has been developed implementing context-aware profiles. Similarity metrics and profile matching strategies are presented and assesed. In a flexible manufactoring systems applications scenario we demonstrate its potentials in the context of wireless peer ensembles. © 2006 IEEE.

In order to study the quality risk of large-scale clusters of engineering project and makes the characteristic analysis of large-scale clusters of engineering project and evaluates quality risk, the author uses analytic hierarchy process to quantify quality risk factor, and the following conclusions are obtained: (a) Construction management unit that makes the project decision-making mainly controls the QRM, comparatively speaking, it has little control over quality risk when the project is completed and ready to get acceptance (b) In the project decision-making stage, the Construction Technology has the greatest influence on the project quality management. This paper puts forward the suggestion that the influence of quality risk factors should be quantified by associated experts, so as to provide a reference for the construction quality management of large-scale cluster projects. © The Authors, published by EDP Sciences.

The present paper deals with automatic segmentation of mosaics, whose aim is obtaining a digital representation of the mosaic where the shape of each tile is recovered. This is an important step, for instance, for preserving ancient mosaics. By using a ground-truth consisting of a set of manually annotated mosaics, we objectively compare the performance of some existing recent segmentation methods, based on a simple error metric taking into account precision, recall and the error on the number of tiles. Moreover, we introduce some mosaic-specific hardness estimators (namely some indexes of how difficult is the task of segmenting a particular mosaic image). The results show that the only segmentation algorithm specifically designed for mosaics performs better than the general purpose algorithms. However, the problem of segmentation of mosaics appears still partially unresolved and further work is needed for exploiting the specificity of mosaics in designing new segmentation algorithms.

Identifying evolvability for integration 1st

The seamless integration of commercial-off-the-shelf (COTS) components offers many benefits associated with reuse. Even with successful composite applications, unexpected interoperability conflicts can arise when COTS products are upgraded, new components are needed, and the application requirements change. Recent approaches to integration follow pattern-based design principles to construct integration architecture for the composite application. This integration architecture provides a design perspective for addressing the problematic interactions among components within the application environment. However, little attention has been paid to the evolvability of these architectures and their embedded functionality. In this paper, we discuss the need for design traceability based on the history of interoperability conflicts and resolution decisions that comprise the integration architecture. Additionally, we advocate that certain functional aspects of a pattern can be pinpointed to resolve a conflict. Combining these two aspects of integration architecture design, we illustrate that often evolution is possible with minimal changes to the integration solution. © Springer-Verlag Berlin Heidelberg 2002.

Sentiment analysis is the method of identifying and classifying the views of users from text documents into different sentiments, such as positive, negative or neutral. Sentiment analysis can be employed to extract structured and informative knowledge from unstructured text pieces. This knowledge can serve as an important source of information for decision support systems and individual decision makers. Sentiment analysis plays an important role in many fields like education, where student input is crucial for assessing the effectiveness of educational institutions. In this paper, we present a machine learning based approach to sentiment analysis on students’ evaluation of higher educational institutions. We analyze a corpus containing approximately 700 student reviews written in Turkish, with the use of conventional text representation schemes and machine learning classifiers. In the experimental analysis, three conventional text representation schemes (i.e., term-presence, term-frequency, TF-IDF scheme) and three N-gram models (1-gram, 2-gram and 3-gram) have been considered in conjunction with four classifiers (i.e., support vector machines, Naïve Bayes, logistic regression, and random forest algorithm). The predictive performance of four ensemble learners (i.e., AdaBoost, Bagging and Random Subspace and voting algorithm) have been also evaluated. The empirical results indicate that machine learning based approach yields promising results on students’ evaluation of higher educational institutions. © 2021, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.
