We present Neu Reach, a tool that uses neural networks for predicting reachable sets from executions of a dynamical system. Unlike existing reachability tools, NeuReach computes a reachability function that outputs an accurate over-approximation of the reachable set for any initial set in a parameterized family. Such reachability functions are useful for online monitoring, verification, and safe planning. Neu Reach implements empirical risk minimization for learning reachability functions. We discuss the design rationale behind the optimization problem and establish that the computed output is probably approximately correct. Our experimental evaluations over a variety of systems show promise. Neu Reach can learn accurate reachability functions for complex nonlinear systems, including some that are beyond existing methods. From a learned reachability function, arbitrary reachtubes can be computed in milliseconds. NeuReach is available at https://***/sundw2014/Neureach.

Diagnosability is a fundamental problem of partial observable systems in safety-critical design. Diagnosability verification checks if the observable part of system is sufficient to detect some faults. A counterexample to diagnosability may consist of infinitely many indistinguishable traces that differ in the occurrence of the fault. When the system under analysis is modeled as a Buchi automaton or finite-state Fair Transition System, this problem reduces to look for ribbon-shaped paths, i.e., fair paths with a loop in the middle. In this paper, we propose to solve the problem by extending the liveness-to-safety approach to look for lasso-shaped paths. the algorithm can be applied to various diagnosability conditions in a uniform way by changing the conditions on the loops. We implemented and evaluated the approach on various diagnosability benchmarks.

Electronic noses, such as chemiresistive gas sensors, are important tools for environmental monitoring, public health and food quality. throughout the measurement process, pattern recognition algorithms are used to map the electrical sensor measurements to a gas concentration. When analyzing gaseous mixtures with such devices, cross-sensitivities are likely to occur, which are related to the selectivity of the sensor materials. In the prediction process, cross-sensitive sensor signals can lead to false positive predictions and a loss in measurement accuracy. In this work, we thoroughly study the impact of the degree of crosssensitivity on the gas concentration prediction performance of neural networks in graphene-based gas sensor arrays. the study was conducted by using a simulation model of a chemiresistive gas sensor to simulate an array of two sensors with different levels of cross-sensitivity to two different target gases. Subsequently, two neural network algorithms were trained and evaluated on the datasets withthe varying cross-sensitivity levels. Our analysis shows that a certain threshold regarding the independence of the array signals is necessary in order to ensure a sufficient gas discrimination and concentration estimation performance of the applied machine learning algorithms. Furthermore, it was also observed that a combination of a highly and poorly selective sensor, as implemented by filtering techniques, can also provide adequate results, when using suitable algorithms.

We present NORMA, a tool for the modeling and analysis of Relay-based Railways Interlocking systems (RRIS). NORMA is the result of a research project funded by the Italian Railway Network, to support the reverse engineering and migration to computer-based technology of legacy RRIS. the frontend fully supports the graphical modeling of Italian RRIS, with a palette of over two hundred basic components, stubs to abstract RRIS subcircuits, and requirements in terms of formal properties. the internal component based representation is translated into highly optimized Timed NuXmv models, and supports various syntactic and semantic checks based on formal verification, simulation and test case generation. NORMA is experimentally evaluated, demonstrating the practical support for the modelers, and the effectiveness of the underlying optimizations.
