As an emerging portable service platform, OSGi is now taking a more and more important role in Ubiquitous Computing environment. As a module management framework, OSGi provides the functions of dynamic loading and unloading software modules at runtime. But its use is limited because it is centralized and single programming language supported. In this paper we present LIR-OSGi, an extended framework of OSGi, which is designed to add the distribution and programming language independence to OSGi. Meanwhile it is easy to use for developers because of the transparence of service invocation and automation of distribution. Not like OSGi which can be applied only on the Java platform, LIR-OSGi makes programs which may be written in different programming languages be able to call each other transparently so that it can be applied in many different platforms such as DotNet Framework and so on. This brings much convenience to the program development in a distributed and heterogeneous environment.

This paper presents ReverseNER, a method aimed at overcoming the limitation of large language models (LLMs) in zero-shot named entity recognition (NER) tasks, arising from their reliance on pre-provided demonstrations. ReverseNER tackles this challenge by constructing a reliable example library composed of dozens of entity-labeled sentences, generated through the reverse process of NER. Specifically, while conventional NER methods label entities in a sentence, ReverseNER features reversing the process by using an LLM to generate entities from their definitions and subsequently expand them into full sentences. During the entity expansion process, the LLM is guided to generate sentences by replicating the structures of a set of specific feature sentences, extracted from the task sentences by clustering. This expansion process produces dozens of entity-labeled task-relevant sentences. After constructing the example library, the method selects several semantically similar entity-labeled examples for each task sentence as references to facilitate the LLM’s entity recognition. We also propose an entity-level self-consistency scoring mechanism to improve NER performance with LLMs. Experiments show that ReverseNER significantly outperforms other zero-shot NER methods with LLMs, marking a notable improvement in NER for domains without labeled data, while declining computational resource consumption.

The manufacturing industry is constantly seeking innovative solutions to optimize machining processes. However, there is a lack of efficient digital platforms that fully meet the flexibility, service composition, and affordability needs of the manufacturing industry, in particular for small and mediumsized enterprises (SMEs). This paper introduces the OptiTwin platform, a novel data-driven system designed to enhance machining process optimization for SMEs. The OptiTwin platform was developed with a focus on data acquisition, management, and analysis based on data driven models. The functionalities of the platform were validated through a drilling use case at Mondragon University's high-performance machining laboratory, demonstrating its effectiveness in real-time tool condition monitoring. The results showcase the potential of OptiTwin in optimizing machining processes and empowering SMEs with data-driven insights for enhanced productivity and quality assurance.

A small group of fault tolerance practitioners met in June, 1991, to attempt to identify how fault tolerance is being applied today, why fault tolerance is underused, and what can be done to bring fault tolerant practices into wider use. In this paper, a public forum is provided for other practitioners with diverse backgrounds to respond to the main conclusion of that workshop: that the state of the practice is the state of the art, i.e., that the practice is more art than engineering. Practitioners use a variety of fault tolerance techniques without the assurance that the contribution made by these techniques to dependability or safety is worth the investment. The conclusions of the workshop are addressed by representatives of Hitachi Ltd., Martin Marietta Corp., ASEA Brown Boveri Research Center, Sequoia systems Inc., and the Honeywell Commercial Flight systems group. © 1992 IEEE.

Teaching software engineering has been recognized as an important challenge for computer science undergraduate programs. Instruction in such area requires not only to deliver theoretical knowledge, but also to perform practical experiences that allow students to assimilate and apply such knowledge. This paper presents some results of two Computer-Supported Collaborative Learning (CSCL) experiences that involved students of software engineering courses from four Latin American Universities. The obtained results were satisfactory and indicate the reported collaborative activity could be appropriate to address teaching software engineering.

Business analytics is an important means of gaining new insights and understanding of business performance. Data mining technology provides information needed by business analytics based on data. But due to the barriers of skill, resource and cost, business analytics is hard to carry out and put into practice for small and even medium sized enterprises. This paper presents a novel concept named Highly Consumable Business Analytics (HCBA) aiming to improve consumability of business analytics. We discuss the ways to simplify the use of data mining algorithms, establish end-to-end integrated lifecycle management of model and ultimately wrap models into web service to provide model-wise services. We propose a general reference architecture of HCBA. And a prototype is designed and implemented based on this architecture.

7.2.3 Thermal/Acoustic trade-off design for Consumer Electronics in a distributed design environment

INCOSE International Symposium 2009年第1期19卷 1126-1138页

Today's market demand for smaller, more powerful consumer electronics poses a major challenge to the rapid design of products. In addition, the ability to perform strategic coordination amongst different stakeholders within the enterprise increasingly becomes an important criterion to enable global engineering. We begin the paper with an introduction to a typical design process involving distributed design teams In particular the process allows the thermal-acoustic design of cavities, i.e. air space inside the enclosure, in terms of flow rate and acoustic radiation resistance. Then we proceed with the investigation of an approach leveraging recent modelling technology to support such a process efficiently. The process makes use of the system modelling language (SysML.) as product description support and the Design Structure Matrix as an analytical design tool. We use the model and the DSM as a means to drive numerical simulation and perform trade-off studies. Simulation results show that performing trade-off study in the early system design phase leads to a potentially optimal module layout for the problem studied. © 2009 The Authors.

Assessing Safety-Critical systems from Operational Testing: A Study on Autonomous Vehicles

arXiv 2020年

作者： Zhao, Xingyu Salako, Kizito Strigini, Lorenzo Robu, Valentin Flynn, David Smart System Group School of Engineering and Physical Sciences Heriot-Watt University EdinburghEH14 4AS United Kingdom Centre for Software Reliability School of Mathematics Computer Science and Engineering City University of London Northampton SquareEC1V 0HB United Kingdom

Context: Demonstrating high reliability and safety for safety-critical systems (SCSs) remains a hard problem. Diverse evidence needs to be combined in a rigorous way: in particular, results of operational testing with other evidence from design and verification. Growing use of machine learning in SCSs, by precluding most established methods for gaining assurance, makes evidence from operational testing even more important for supporting safety and reliability claims. Objective: We revisit the problem of using operational testing to demonstrate high reliability. We use Autonomous Vehicles (AVs) as a current example. AVs are making their debut on public roads: methods for assessing whether an AV is safe enough are urgently needed. We demonstrate how to answer 5 questions that would arise in assessing an AV type, starting with those proposed by a highly-cited study. Method: We apply new theorems extending our Conservative Bayesian Inference (CBI) approach, which exploit the rigour of Bayesian methods while reducing the risk of involuntary misuse associated (we argue) with now-common applications of Bayesian inference;we define additional conditions needed for applying these methods to AVs. Results: Prior knowledge can bring substantial advantages if the AV design allows strong expectations of safety before road testing. We also show how naive attempts at conservative assessment may lead to over-optimism instead;why extrapolating the trend of disengagements (take-overs by human drivers) is not suitable for safety claims;use of knowledge that an AV has moved to a "less stressful" environment. Conclusion: While some reliability targets will remain too high to be practically verifiable, our CBI approach removes a major source of doubt: it allows use of prior knowledge without inducing dangerously optimistic biases. For certain ranges of required reliability and prior beliefs, CBI thus supports feasible, sound arguments. Useful conservative claims can be derived from limite
