Semantic segmentation (SS) provides the meaning of visual scenes, thus being a key stage for navigation and environment's perception. This paper presents a solution for SS compatible with assistive wearable systems equipped with color and depth cameras. In order to ensure a compact and robust description of input color-based images, both 2D and 3D features are extracted at superpixel level, after correcting the displacements of the camera by means of adequate rectifications. Random Forests (RF) are called for solving the classification problem. In this context, this paper introduces a multilayer RFbased classifier, including a separate layer for label correction. Additional two other correcting methods are proposed for the first layers of the classifier, i.e. a fast method investigating the majority label around each object, and several customizations of the graph cut algorithm using convenient cue weights. The performance of the suggested approach is experimentally verified on diverse urban street scenes.

The main goal of the paper is to study the equilibria of a nonlinear system, proving the existence and uniqueness of an equilibrium point in the positive ortant. We also provide numerically tractable conditions (by using Linear Matrix Inequalities techniques) to check the asymptotic stability of the equilibrium point. An illustrative numerical example is closing the paper along with some conclusions. © 2018, Politechnica University of Bucharest. All rights reserved.

Defect engineering in metal oxides presents a promising approach for tailoring material properties. This strategy enhances gas sorption, catalysis, and control over key physical characteristics such as bandgap, magnetic behavior, and electrical conductivity. Despite its potential, the role of defect engineering in advancing metal oxide semiconductor (MOS) gas-sensing performance remains underexplored. This review introduces defect engineering strategies, emphasizing their applications in gas sensing. Gas sensors play a vital role in environmental monitoring, industrial safety, healthcare, and in improving energy efficiency. The demand for advanced gas sensors has never been more critical, given the need for real-time, accurate, and cost-effective detection of pollutant gases. MOS-based gas sensors are widely used in air quality monitoring, industrial safety, and health diagnostics. Vacancies and defect architectures in MOS have been widely studied for their role in sensing performance, as they fundamentally influence sensor efficiency. The effectiveness of MOS sensors largely depends on the type and concentration of defects. This review introduces vacancies and defects in MOS, followed by an in-depth discussion of defect types, factors influencing defect formation, and their role in charge transport. Additionally, it examines the correlation between elemental chemical properties and defect chemistry. Special attention is given to the defect chemistry of metal oxides, including TiO 2 , ZnO, Co 3 O 4 , ZrO 2 , WO 3 , and CeO 2 . It concludes with an examination of surface engineering methods for defect control to improve gas-sensing capabilities.

RESTful Web Services – A Question of Standards

RESTful Web Services – A Question of Standards

International Conference on System Theory, control, and Computing (ICSTCC)

Roy Thomas Fielding defined the term REST as an architectural style for distributed hypermedia based systems in the year 2000. Since this initial definition, the term itself became a buzzword used in almost any web-related development. From simple, basic web applications, to highly complex web service/microservice-based solutions, almost everyone and everything talks REST and RESTful. Moreover, the Web context implies that these developments are usually realised over HTTP. In this paper, we first analyse the impact of this architectural style on distributed application development. A careless application of this model and its underlying HTTP standards could severely impact on the overall quality of any RESTful based solution. Following, we submit our own model for user data and session handling tasks to illustrate the correct approach to RESTful web service design techniques. This model offers all the advantages of the aforementioned architectural style while providing the required functionality for the authentication and authorisation components of all web based applications.

Although the response mechanism of carbon nanotubes (CNTs) based sensors exposed to a variety of gases has been extensively discussed and studied, pristine onion-like carbon (OLCs), part from the same class of fullerenes, have not been fully investigated as sensing application. A room-temperature working chemiresistor based on onion-like carbons (OLCs) as sensing element with good sensitivity has been developed and tested with the main purpose of being implemented within the next generation of gas sensors. Many industries require a room temperature working gas sensor without an external heating source: leakage detections of explosive gases (such as hydrogen), detection of flammable gases and explosives in plants, biomedicine and pharmaceutics, monitor combustibles, early detection of fires, real-time detections of toxic or pathogenic gases in industries, ambient environmental monitoring and control. One industry that would also benefit from development of such a sensor is the food industry which requires a smart label that warns the consumer on the presence of toxic substances to avoid ingestion of contaminated food. Ingestion of food contaminated with different chemicals due to a malfunctioned manufacturing process or due to food spoilage from an improper storage could trigger severe trauma within human body. © 2018 IMEKO-International Measurement Federation Secretariat.

This paper presents a small-gain theorem for networks composed of a countably infinite number of finite-dimensional subsystems. Assuming that each subsystem is exponentially input-to-state stable, we show that if the gain operator, collecting all the information about the internal Lyapunov gains, has a spectral radius less than one, the overall infinite network is exponentially input-to-state stable. The effectiveness of our result is illustrated through several examples including nonlinear spatially invariant systems with sector nonlinearities and a road traffic *** Codes 37B25, 37L15, 93D05, 93A15 Copyright © 2019, The Authors.

Diffusion-weighted MRI (DWI) is essential for stroke diagnosis, treatment decisions, and prognosis. However, image and disease variability hinder the development of generalizable AI algorithms with clinical value. We address this gap by presenting a novel ensemble algorithm derived from the 2022 Ischemic Stroke Lesion Segmentation (ISLES) challenge. ISLES’22 provided 400 patient scans with ischemic stroke from various medical centers, facilitating the development of a wide range of cutting-edge segmentation algorithms by the research community. By assessing them against a hidden test set, we identified strengths, weaknesses, and potential biases. Through collaboration with leading teams, we combined top-performing algorithms into an ensemble model that overcomes the limitations of individual solutions. Our ensemble model combines the individual algorithms’ strengths and achieved superior ischemic lesion detection and segmentation accuracy (median Dice score: 0.82, median lesion-wise F1 score: 0.86) on our internal test set compared to individual algorithms. This accuracy generalized well across diverse image and disease variables. Furthermore, the model excelled in extracting clinical biomarkers like lesion types and affected vascular territories. Notably, in a Turing-like test, neuroradiologists consistently preferred the algorithm’s segmentations over manual expert efforts, highlighting increased comprehensiveness and precision. Validation using a real-world external dataset (N=1686) confirmed the model’s generalizability (median Dice score: 0.82, median lesion-wise F1 score: 0.86). The algorithm’s outputs also demonstrated strong correlations with clinical scores (admission NIHSS and 90-day mRS) on par with or exceeding expert-derived results, underlining its clinical relevance. This study offers two key findings. First, we present an ensemble algorithm that detects and segments ischemic stroke lesions on DWI across diverse scenarios on par with expert (neuro)rad

The modern approach to the quality of service (QoS) claims that problems of assurance of the required QoS parameters may occur not only in core networks (as the classic approach assumes), but also in access networks (including local networks, or LANs), especially if the access network is of broadcast type, such as the IEEE 802.11 wireless LAN. In the case of broadcast LANs, QoS assurance in the network layer should be associated with the QoS assurance in the data link layer. The aim of this paper is to propose such an association between the 802.11 QoS assurance and the QoS assurance based on the Traffic Flow Description (TFD) option of the IP protocol. The TFD was specified by the Authors in the IETF’s working document (Internet Draft), and was intended to describe Internet traffic for the purpose of dynamic resource reservations. The TFD-based QoS assurance offers dynamic reservations for micro-flows (single data real-time streams or non-real-time flows). The proposed method associates TFD and 802.11 QoS architectures in a way similar to the association of the DiffServ architecture and the 802.11 QoS, i.e. by the mapping of corresponding signalling. This mapping was designed and then implemented by the Authors in a Linux kernel. Results of laboratory experiments carried out in a test network show that the proposed mappings sufficiently promote traffic described by the TFD option in 802.11 WLAN and protect it against degradation. The proposed method includes the mapping of static signalling. Mapping of dynamic information conveyed in the TFD option is also possible and will be a subject of further research. The mapping between TFD and IEEE 802.11 user priorities and access categories will allow a 802.11 network to preserve TFD-based QoS in wireless links. © Springer Nature Switzerland AG 2018.

This paper deals with the complex problem of reliability evaluation of stochastic networks in which both links and nodes failures are considered, and compares two approximate approaches able to reduce the computation time: a sum of disjoint products (SDP) approach and another based on Monte Carlo simulation. In case of the SDP approach, the reliability is computed based on the minimal paths. In a first stage, only the links of the network are considered, and a `multiple variables inversion' technique for developing the set of minimal paths into a sum of disjoint products is applied. Then, in a second stage, each term of the set of disjoint Iink- products is processed separately taking into consideration the reliability values for both links and adjacent nodes. In case of Monte Carlo simulation, for speeding up the method and reducing the computation time, both minimal paths and cuts are considered. Also, other acceleration techniques are applied.
