In-field test of electronic devices is becoming increasingly important due to the wide adoption of electronic systems in safety-critical applications. Hence, it is crucial to devise and deploy effective solutions supporting the test during the operational phase of all the components of an electronic system, including the memory modules embedded in a SoC. Some key aspects include the possible reuse of HW infrastructures introduced for end-of-manufacturing test, the need for limited intrusiveness with respect to the application, and the achievable defect coverage. The paper discusses the main challenges in this area and possible solutions, as well as future trends. © 2017 IEEE.

In today's world, large volumes of medical data are being continuously generated, but their value is severely undermined by our inability to translate them into knowledge and, ultimately, actions. Data mining techniques allow the extraction of previously unknown interesting patterns from large datasets, but their complexity limits their practical diffusion. Data-driven analysis is a multi-step process, in which health care professionals define analysis goals and assess extracted knowledge, while computer scientists tackle the non trivial task of driving the miner system analysis activity. This paper addresses the mining activity from a different perspective. We believe that mining systems should be able to devise which knowledge could be most interesting to users and extract actionable knowledge from large medical datasets, with minimal user intervention. More specifically, mining systems should be capable of (i) devising viable end-goals for a specific dataset (i.e., that yield actionable knowledge to the user and are feasible given the dataset characteristics and size), based on the expertise acquired during the analysis of previous datasets, and (ii) extracting a manageable set of knowledge. Automated data analysis should fuel the next generation of medical mining systems, thus enabling users to automatically mine massive data repositories. © 2016 IEEE.

Industrial process control IP networks support communications between process control applications and devices. Communication faults in any stage of these control networks can cause delays or even shutdown of the entire manufacturing process. The current process of detecting and diagnosing communication faults is mostly manual, cumbersome, and inefficient. Detecting early symptoms of potential problems is very important but automated solutions do not yet exist. Our research goal is to automate the process of detecting and diagnosing the communication faults as well as to prevent problems by detecting early symptoms of potential problems. To achieve our goal, we have first investigated real-world fault cases and summarized control network failures. We have also defined network metrics and their alarm conditions to detect early symptoms for communication failures between process control servers and devices. In particular, we leverage data mining techniques to train the system to learn the rules of network faults in control networks and our testing results show that these rules are very effective. In our earlier work, we presented a design of a process control network monitoring and fault diagnosis system. In this paper, we focus on how the fault detection part of this system can be improved using data mining techniques.

Arithmetic operation's execution time in real-time system is bounded by deadlines. The method commonly used to meet these deadlines is by employing any suitable process-scheduling algorithm, which may contain a potential weakness. If time needed to operate is longer than its deadline, then the result's quality will be poor. This is mainly caused by the algorithms of the arithmetic operations commonly used nowadays do not choose the most significant data to be processed first. This research tries to design new algorithm and its processing unit that works based on real-time principles, which starts its computation process from the highest valued digit and provides its intermediate-results that can be accessed anytime during the process. Designing tool used in this research is MAX+plus II Baseline 10.2 software. This research accomplishes in showing the performance of the new algorithm and its processing unit, which is better than the performance of the conventional algorithm.

Robot audition, encompassing Sound Source Localization (SSL), Sound Source Separation (SSS), and Automatic Speech Recognition (ASR), enables robots and smart devices to acquire auditory capabilities similar to human hearing. Despite their wide applicability, processing multi-channel audio signals from microphone arrays in SSL involves computationally intensive matrix operations, which can hinder efficient deployment on Central Processing Units (CPUs), particularly in embedded systems with limited CPU resources. This paper introduces a GPU-based implementation of SSL for robot audition, utilizing the Generalized Singular Value Decomposition-based Multiple Signal Classification (GSVD-MUSIC), a noise-robust algorithm, within the HARK platform, an open-source software suite. For a 60-channel microphone array, the proposed implementation achieves significant performance improvements. On the Jetson AGX Orin, an embedded device powered by an NVIDIA GPU and ARM®Cortex™-A78AE v8.2 64-bit CPUs, we observe speedups of 4645.1× for GSVD calculations and 8.8× for the SSL module, while speedups of 2223.4× for GSVD calculation and 8.95× for the entire SSL module on a server configured with an NVIDIA A100 GPU and AMD EPYC™ 7352 CPUs, making real-time processing feasible for large-scale microphone arrays and providing ample capacity for real-time processing of potential subsequent machine learning or deep learning tasks. © 2025, CC BY-NC-ND.

Online Adaption of Motion Paths to Time-Varying Constraints using Homotopies

引用

IFAC-PapersOnLine 2017年第1期50卷 3331-3337页

作者： Kontny D. Stursberg O. Control and System Theory Dept. of Electrical Engineering and Computer Science University of Kassel Germany

This paper presents a method for optimal point-to-point control of linear discrete-time systems with time-varying non-convex state constraints, as arising for problems of avoiding moving obstacles. While common approaches like MPC with mixed-integer programming (MIP) can quickly become time-demanding, the presented approach efficiently computes circumventing near-optimal trajectories by using homotopy properties. In a first step, a range of offline selected trajectories is used to span a region of homotopic trajectories, for which the transitioning behavior between these is determined by semi-definite programming (SDP). The online part then determines with low computational effort a collision-free and near-optimal homotopic trajectory. The procedure maps the moving obstacles for relevant collision-critical time steps into the homotopy space, and determines a suitable trajectory by a tree-search of moderate size. The circumventing trajectories and the resulting computation times are illustrated by simulation. © 2017

Magnetic measurement is a typical inverse problem in Biomedical field. In this kind of problem we always need to locate the positions and moments of one or more magnetic dipoles. Although using the traditional methods to solve this kind of inverse problem has all kinds of shortcomings, BPNN (Back Propagation Neural Networks) method can be used to solve this typical inverse problem fast enough for real time measurement. In the traditional BPNN method, gradient descent search method is performed for error propagation. In this paper the authors propose a new algorithm that Newton method is performed for error propagation. For the cost function is highly nonconvex in the magnetic measurement problem, the new kind of BPNN can get convergent results quickly and precisely. A simulation result for this method is also presented.

This work presents a simulation study of an event-based selective control strategy for a raceway reactor. The control system aims are to maintain simultaneously a pH and dissolved oxygen within specific limits. In the analyzed control scheme, the pH value is prioritized over the dissolved oxygen, since it has a critical influence on the process performance. Besides, the dissolved oxygen also influences the photosynthesis rate and should be kept within the limits. The control structure is evaluated through simulation, where a nonlinear model for microalgae culture in the raceway photobioreactor is used. Analysis of different configurations allows to determine the most adequate control system setup to achieve the desired goals. The obtained results show that combination of an event-based approach with selective control allows to increase the overall productivity as well as to address effective CO2utilization and aeration system energy minimization. © 2016

Context: the presence of several languages interacting each other within the same project is an almost universal feature in software development. Earlier work shows that this interaction might be source of problems. Objective: we aim at identifying and characterizing the cross-language interactions at semantic level. Method: we took the commits of an open source project and analyzed the cross-language pairs of files occurring in the same commit to identify possible semantic interactions. We both defined a taxonomy and applied it. Result: we identified 6 categories of semantic interactions. The most common category is the one based on shared ids, the next is when an artifact provides a description of another artifact. Conclusion: the deeper knowledge of cross-language interactions represents the basis for implementing a tool supporting the management of this kind of interactions and the detection of related problems at compile time. © 2013 IEEE.

In computer vision, texture plays an important role. In this work we propose five human perceptual texture features heuristically extracted. Since a modeling can not be obtained from these features, we use a discriminant analysis technique to examine the discriminant power of each texture descriptor in order to select the most relevant. This task is done by a stepwise inclusion of variables indicating, furthermore, whether all of them are valuable and necessary producing a set of optimal discriminant variables. These selection procedures have been tested using Brodatz texture images, a benchmark in texture analysis. © Springer-Verlag Berlin Heidelberg 1998.
