This paper is concerned with runtime verification of object-oriented software system. We propose a novel algorithm for monitoring the individual behaviour and interaction of an unbounded number of runtime objects. This allows for evaluating complex correctness properties that take runtime data in terms of object identities into account. In particular, the underlying formal model can express hierarchical interdependencies of individual objects. Currently, the most efficient monitoring approaches for such properties are based on lookup tables. In contrast, the proposed algorithm uses union-find data structures to manage individual instances and thereby accomplishes a significant performance improvement. The time complexity bounds of the very efficient operations on union-find structures transfer to our monitoring algorithm: the execution time of a single monitoring step is guaranteed logarithmic in the number of observed objects. The amortised time is bound by an inverse of Ackermann's function. We have implemented the algorithm in our monitoring tool Mufin. Benchmarks show that the targeted class of properties can be monitored extremely efficient and runtime overhead is reduced substantially compared to other tools.

On Freeze LTL with Ordered Attributes 1

This paper is concerned with Freeze LTL, a temporal logic on data words with registers. In a (multi-attributed) data word each position carries a letter from a finite alphabet and assigns a data value to a fixed, finite set of attributes. The satisfiability problem of Freeze LTL is undecidable if more than one register is available or tuples of data values can be stored and compared arbitrarily. Starting from the decidable one-register fragment we propose an extension that allows for specifying a dependency relation on attributes. This restricts in a flexible way how collections of attribute values can be stored and compared. This conceptual dimension is orthogonal to the number of registers or the available temporal operators. The extension is strict. Admitting arbitrary dependency relations, satisfiability becomes undecidable. Tree-like relations, however, induce a family of decidable fragments escalating the ordinal-indexed hierarchy of fast-growing complexity classes, a recently introduced framework for non-primitive recursive complexities. This results in completeness for the class F is an element of(0). We employ nested counter systems and show that they relate to the hierarchy in terms of the nesting depth.

7th International Symposium on Leveraging Applications of Formal Methods, Verification and Validation (ISoLA)

作者： Leucker, Martin Schmitz, Malte Tellinghusen, Danilo A. Univ Lubeck Inst Software Engn & Programming Languages Lubeck Germany

In this tool paper we present a software development kit (SDK) for the Open Surgical Communication Protocol (OSCP) that supports the development of interconnected medical devices according to the recent IEEE 11073 standards for interoperable medical device communication. Building on service-oriented architecture (SOA), dynamically interconnected medical devices publish their connectivity interface, via which these systems provide data and can be controlled. To achieve the safety requirements necessary for medical devices, our tool, the OSCP Device Modeler, allows the specification of temporal assertions for the respective data streams of the systems and generates automatically corresponding monitors that may be used during testing, but also during the application in field to ensure adherence to the interface specification. A further tool, the OSCP Swiss Army Knife, allows subscribing to the services provided via the interfaces of the system under development and thereby supports its debugging. The whole OSCP SDK makes heavy use of runtime verification techniques and shows their advantages in this application area.

The effective development and dissemination of the open integration for the next generation of operating rooms require a comprehensive testing environment. In this paper, we present the various challenges to be addressed in demonstration applications, and we discuss the implementation approach, the foci of the demonstration sites and the evaluation efforts. Overall, the demonstrator setups have proven the feasibility of the service-oriented medical device architecture (SOMDA) and real-time approaches with a large variety of example applications. The applications demonstrate the potentials of open device interoperability. The demonstrator implementations were technically evaluated as well as discussed with many clinicians from various disciplines. However, the evaluation is still an ongoing research at the demonstration sites. Technical evaluation focused on the properties of a network of medical devices, latencies in data transmission and stability. A careful evaluation of the SOMDA design decisions and implementations are essential to a safe and reliable interoperability of integrated medical devices and information technology (IT) system in the especially critical working environment. The clinical evaluation addressed the demands of future users and stakeholders, especially surgeons, anesthesiologists, scrub nurses and hospital operators. The opinions were carefully collected to gain further insights into the potential benefits of the technology and pitfalls in future work.

INTERNATIONAL JOURNAL ON software TOOLS FOR TECHNOLOGY TRANSFER 2016年第6期18卷 629-651页

The jABC is a framework for process modelling and execution according to the XMDD (eXtreme model-driven design) paradigm, which advocates the rigorous use of user-level models in the software development process and software life cycle. We have used the jABC in the domain of scientific workflows for more than a decade now-an occasion to look back and take stock of our experiences in the field. On the one hand, we discuss results from the analysis of a sample of nearly 100 scientific workflow applications that have been implemented with the jABC. On the other hand, we reflect on our experiences and observations regarding the workflow development process with the framework. We then derive and discuss ongoing further developments and future perspectives for the framework, all with an emphasis on simplicity for end users through increased domain specificity. Concretely, we describe how the use of the PROPHETS synthesis plugin can enable a semantics-based simplification of the workflow design process, how with the jABC4 and DyWA frameworks more attention is paid to the ease of data management, and how the Cinco SCCE Meta-Tooling Suite can be used to generate tailored workflow management tools.

Annual Conference of Industrial Electronics Society

This paper presents monitoring as a service for networked medical cyber-physical systems in the operating room based on the recent IEEE 11073 standards for interoperable medical device communication. Runtime Verification techniques are used to allow for a formal specification and verification. Based on the specification so called monitors are automatically synthesized. At runtime, the monitors observe the communication of the interconnected systems and examine whether they adhere to the specification. This facilitates the handling of the high safety requirements of medical cyber-physical systems and to increase their reliability. In addition, we outline the development and deployment process of the monitors and depict how the framework can be extended to react when misbehavior is detected. As a case study the interconnection of an ultrasound dissector and a microscope is used. Our benchmarks show that the monitoring overhead is substantially lower than what is required for our practical application.

Description of fouling, surface changes and heterogeneity of membranes by color-based digital image analysis

This paper proposes the implementation of digital image analysis for the easy, fast and simple description of membrane surface changes as a result of fouling or any process with capacity to produce, directly or indirectly, color changes on the surface. For that, a color amount descriptor is used to generate a quantitative measurement of changes experimented on membrane. By ultrafiltration experiments, membranes with different cut-off (1, 10, 50 and 100 kDa) were fouled using aqueous extracts of plant leaves (P. alvaradoii). Surface changes of membranes were analyzed by attenuated total reflectance, permeability analysis and image analysis. Results evidence the applicability of surface color index (I) for the description of fouling and membrane surface changes. In addition, results suggest that image analysis using color-based quantitative descriptors can be used to description of surface anisotropy of membranes and easily correlated with permeability and fouling layer thickness.

In this paper the boundary value problem for the thermal conductivity of an isotropic piecewise homogeneous plate with a through foreign inclusions, heated heat flow, focused on one of its boundary surfaces is considered. Thermal conductivity of the entire system as a whole is described by means of asymmetric single function. The result is a heat equation with discontinuous and singular coefficients for the given design. After a piecewise linear approximation of the temperature on the surface layers of the plate and side turn applied the integral Fourier transform, resulting in built numerically-analytical solution to the original problem. Calculate and analyze the temperature field in the structure "plate-inclusion" (plate material - ceramics VK94-I, inclusion of material - silver).

Development of the mobile robot can be executed in two different ways. Firstly, this creation of the built-in system, secondly, the use of "ready to use" industrial components. With distribution of the industrial mobile robots in the market there are more and more components which can be used for creation of all control system and sensors of the robot mobile platform. Use of the ready components doesn't demand the hardware development that accelerates time of development and reduces cost. The chassis of the Belarus-132 mini-tractor is used as a platform of robotic system in the research, "creation" of the program for traffic control is required. Results of the practical research on design and model development of a mobile robotic complex are given.

This demo shows how two objects that each live within their own world, i.e., the are not in each others transitive closure of object references, can get to know each other in a well-defined manner using a new language construct. The basic problem is that if two object are in different worlds, there is no way they can communicate. Our proposed language construct, added to the Emerald programming language, allows objects in close proximity to get to know each other in a well-defined, language based manner.
