A smart home allows automated technology to control systems and appliances to assist daily life activities. In the current work, a prototype of a designed smart home health-aware system is presented. Three predefined ruled agents have been used to gather data, communicate between themselves, interpret the data based on several machine learning algorithms to predict abnormality for cardiac conditions. The paper also compares results obtained by running five machine learning algorithms. The agents function in accordance with predefined dataset describing residents ' age, gender, height, weight, systolic and diastolic blood pressure, cholesterol, and glucose levels, smoking and alcohol consumption habits, and lastly, physical activity. Our plan is to simplify ubiquitous health monitoring for smart home's residents. The proposed solution aims to monitor parametric measurements to alert health specialists in case of emergencies. © 2023 IEEE.

Theoretical studies and experiment analysis of time-domain symmetrical configuration two-probe method are provided in this paper, and the method's feasibility and error separation's precision are discussed. Conclusions can be drawn from the results of simulation and experiment that measurement precision and repeat precision of two-probe method is a little higher that of single-probe method. Though radial random errors can not be separated entirely, the measurement theory of symmetrical configuration two-probe method is simple, and the measurement equipments' precision can be easily ensured. In addition, the data processing can be done directly in time-domain, which is more practicable. Two-probe method is useful in practical measurement. High accuracy can be ensured, especially in the case of measuring the shape errors of big parts with general precision. ©2010 IEEE.

End user monitoring of quality of experience is one of the necessary steps to achieve an effective and winning control over network neutrality. The involvement of the end user, however, requires the development of light and user-friendly tools that can be easily run at the application level with limited effort and network resources usage. In this paper, we propose a simple model to estimate packet loss rate perceived by a connection, by round trip time and TCP goodput samples collected at the application level. The model is derived from the well-known Mathis equation, which predicts the bandwidth of a steady-state TCP connection under random losses and delayed ACKs and it is evaluated in a testbed environment under a wide range of different conditions. Experiments are also run on real access networks. We plan to use the model to analyze the results collected by the "network neutrality bot" (Neubot), a research tool that performs application-level network-performance measurements. However, the methodology is easily portable and can be interesting for basically any user application that performs large downloads or uploads and requires to estimate access network quality and its variations. © 2012 ACM.

Software reuse as an umbrella concept has been around for several decades. Over time, new techniques and approaches have been proposed to implement the concept, from libraries of reusable assets to product lines, to generative methods. These latter techniques are mostly used in intra-organizational reuse, and require considerable formal knowledge over the evolution of technology and required functionality in a domain over several years. On the other end of the spectrum, extra-organizational reuse is based on reuse of off-the-shelf (OTS) software (both open and closed source, acquired for free or for a fee). Here, a limited investment and immediate availability of the assets have widely spread the approach. On the other hand, the reusing organization has no control on the evolution of the functionality and assumptions of the asset. Even when the assets are open source, they are seldom modified. The theme for this ninth meeting is the reuse of off-the-shelf (OTS) components and related problems: * Documentation of OTS components * Processes to identify and select OTS components * Integration and evolution problems * Reliability and security of OTS components and legal issues * Interaction with the developer community or with the vendor The proceedings you are holding cover these issues as well as development and use of product lines, variability modeling, aspect-based development, composition of components and services.

Considering the stochastic delay problems existing in networked control systems, a new control mode is proposed for networked control systems whose delay is longer than a sampling period. Under the control mode, the mathematical model of such a system is established. A stochastic stabilization condition for the system is given. The maximum delay can be derived from the stabilization condition.

Document Clustering is one of the popular techniques that can unveil inherent structure in the underlying data. Two successful models of unsupervised neural networks, Self-Organizing Map (SOM) and Adaptive Resonance Theory (ART) have shown promising results in this task. The high dimensionality of the data has always been a challenging problem in document clustering. It is common to overcome this problem using dimension reduction methods. In this paper, we propose a new two-level neural network based document clustering architecture that can be used for high dimensional data. Our solution is to use SOM in the first level as a dimension reduction method to produce multiple output clusters, then use ART in the second level to produce the final clusters using the reduced vector space. The experimental results of clustering documents from the RETURES corpus using our proposed architecture show an improvement in the clustering performance evaluated using the entropy and the f_measure. © Springer-Verlag Berlin Heidelberg 2004.

Over the last decades, atomic force microscopy (AFM) became one of the most important measuring instruments in various disciplines covering life science, biology, material science, semiconductor industries, and micro- and nanotechnology. Conventional AFM scanning techniques are limited to a 2.5D image acquisition, resulting a simple 2D high-map of the surface. Due to the ongoing miniaturization in semiconductor and nanomanufacturing industries, measurements on the critical dimensions are of growing importance. Additionally, novel measurement tasks as the determination of linewidths or even sidewall roughness arise as need from nanometrology. Especially, the upcoming technology of nanooptics and photonics relies critically on powerful and ultra-precise characterization tools for complex surfaces on the sub-nanoscale. In order to produce suitable optical waveguides and building-blocks, all surface roughness and surface impurities have to be minimized, since the result in severe light diffusion and diffraction. Conventional AFM probes are suitable for 2.5D image acquisitions only and don't allow a correct scanning of complex structures. The pyramidal tip of standard probes cannot scan high aspect ratio structures, which leads to a distorted AFM image and to incorrect trench width and height. Furthermore, a standard tip is not able to contact surfaces with tilt-angles larger than the pyramid's side-angle. In general, this makes sidewall scans impossible at all. To overcome these problems, a novel method for performing sidewall measurements is proposed, based on standard AFM equipment in combination with customized FIB-milled AFM tips. Standard AFM environment is improved with an additional control loop incorporating the torsion of the cantilever as feedback to control the lateral position of the AFM tip. © 2014 IEEE.

Industrial and technical applications of omnidirectional mobile robots, with Mecanum wheels, are continuously gaining in importance because their excellent mobility, especially in areas with static or dynamic obstacles. The perspective of Industry 4.0 imposes an effective and efficient approach for production in general and then, specific to this application, to implement the control algorithm able to deliver to robot the deliberatively and reactively behaviour. An important tool to achieve these goals is virtualization of the prototype and his simulation in a 3D virtual *** paper presents a simplified method of modelling and kinematics simulation in Simscape Multibody™, taking an omnidirectional mobile robot with advantages related to simulation time. The necessary steps to develop inverse kinematics in robots and global reference frame, for specific omnidirectional mobile robot, are depicted in the paper using bottom-up approach with matrix transformation. The 3D modelling process starts from the CAD design, which is then transferred into a Simscape Multibody™ model in order to study the kinematic and dynamic characteristics. Four typical motion models including moving forward, moving laterally, moving in the diagonal direction and rotation have been simulated in Simscape Multibody™. © 2020 IEEE.

In order to improve the accuracy of line losses calculation, and reducing the time-consumption calculation, this paper proposed a novel calculation based on support vector machine for line losses. This paper used support vector machines as the computational model to cause the complex mapping relationship between the original inputs and outputs can be obtained by training, thus greatly reducing the computation and reducing the time-consumption. By setting the SVM kernel function and a number of parameters, the calculation accuracy can be significantly improved. Compared with traditional methods, the calculation method based on support vector machines in reducing the calculation errors and time-consumption has better performances. © 2010 IEEE.

Since being introduced into domestic measurement field during the 1980's, grating-shape capacitive sensors have played an important role in due to their high accuracy and low cost compared to ordinary capacitive sensors and grating respectively. To better arrest the error of this sensor, we primarily employ Matlab to analyze theoretical error in order to calculate optimum ratio of reflecting electrode and emitting electrodes. Based on our analysis, we are able to find out that the optimum ratio is 1.5:1 and thus several structural designs of capacitive sensor are given in this paper. Simulations indicate that theoretical error concerned in this document is better reduced by our designs than that by classic structure. © 2010 IEEE.
