In this paper, a new object recognition framework is presented. The framework includes a variety of object recognition approaches based on Principal Component Analysis (PCA), Linear Discriminant Analysis (LDA), and the K-nearest neighbor (K-NN). A color image vector representation model is also introduced. Based on the representation model, color Eigenspace is constructed using PCA and LDA for feature extraction. The K-NN is adopted as a mechanism for classification. The object recognition framework approaches were tested on Columbia Object Image Library (COIL-100) and Amsterdam Library of Object Images (ALOI) color object databases. Experimental results on these databases evinced the effectiveness of the proposed work with high recognition rates in comparison with the results of previous works in the literature. The recognition rate has reached in some cases 100%. © 2016 IEEE.

New delay-efficient configurable multiplier based on Modified Booth's Algorithm (MBA) and Wallace Tree (WT) structure for multiplying two m-bit operands - where m ranges from 8-bit to 128-bit - is introduced. WT structure has been used to reduce the number of sequential adding stages and speed improvements have been achieved. Modifying Booth's multiplier architecture at a fundamental level is an advantageous concept that sets FPGA based multiplier models apart from rigid-architecture conventional multipliers. In the context of this work, various multipliers, based on MBA and WT, have been developed with the smallest possible time delay. Comparisons have been made between the proposed multiplier implementations and those found in the literature. The comparative results show that the proposed multiplier introduces delay improvement reaches % 42.64. © 2017 IEEE.

This paper presents an intelligent and innovative solution of wireless monitoring of a computerized city using Safe Mobile units, based on S4I development platform. The system is using various networks of vehicular units in order to communicate with each other and with central gateway servers. The end user is accessing a client or a web hosted application for both receiving real-time data from the monitored units and sending out the commands. The major achievement of such a system is reducing the time in which an emergency situation is identified and solved. © 2010 IEEE.

Stability analysis of neutral systems: A delay-dependent criterion

引用

作者： Ionescu, Tudor C. Stefan, Radu Dept. of Mathematics and Natural Sciences University of Groningen Netherlands Dept. of Automatic Control and Computers University Politehnica Bucharest Romania

The main goal of this paper is to investigate the stability of neutral systems, by using the comparison method introduced by Zhang, Knospe and Tsiotras [13] for the standard time-delay case. The central idea consists in replacing the delay by two appropriate Padé approximations, obtaining two comparison systems whose robust stability give a simple delay-dependent stability condition for the (nominal) neutral system. Such a condition guarantees, as in the standard time-delay case, an a priori upper bound for the degree of conservatism induced by the comparison method. This degree depends on the order of the Padé approximation and its estimation makes the difference between this method and other approaches encountered in the literature. The effective computation of the delay margin is reduced to a set of finite dimensional LMI's . © 2009 Springer-Verlag Berlin Heidelberg.

control design for marine autonomous vehicles is a subject of great interest in the control systems. These vehicles are strongly non linear and show complex hydrodynamics effects that make difficult the control design. Besides, the use of underactuated vehicles is very important for different reasons like simplicity, cost, efficiency, etc, so these vehicles and their use for collaborative tasks are main topics of investigation. A non linear control for path following for USVs is presented in this work with an infrastructure capable of performing multiple AUV and ROV in collaborative tasks. So this control law and this infrastructure will be used in future projects for formation control of USVs. © 2009 IFAC.

Coordinating service capacity with dynamic varying, market-driven customer demand in a service business imposes correlating and synchronizing front-office and back-office processes - the first addressing customer relationship management and the second inventory planning, forecasting demand, analytics, and strategic decision making. Front office management (FOM) contributes substantially in coordinating the services requested by guests, and needs to be integrated in an Operations Management Software system specific for hotel business. Research efforts are currently directed towards automating repetitive, time consuming operations included in front office processes that are in great number, initiated by random events and customer actions with variable timing. The paper presents a solution to automate FOM operations that are kept consistent with the business strategy of the organization, and assist front-office workflows involving customers (service requests, service quality assessment) and front line personnel (registration, check in, check out, taxation and invoicing). The solution is based on the Robotic Process Automation (RPA) technology extended with AI-based functionalities for the intelligent process automation and integration with back-office workflows. © 2023 IEEE.

The paper is aimed to describe innovative assets tracking applications using Safe Mobile remote control units, based on S4I development platform. The wireless monitoring system enables different types of vehicular units to communicate with each other. Also, the units are able to contact and to be contacted by a central dispatch entity. Client or web-hosted applications, hosted on central servers, in the cloud, can be accessed by the end user both for receiving real-time data from the monitored units and sending out the commands. The system brings major achievements to the wireless communication in vehicular networks, the most important one being the reduction of the amount of time in which an emergency situation is identified and resolved. © 2010 IEEE.

In this work a simulation platform for uninhabited marine and aerial vehicles is proposed. This platform is based in the MDA (Model Driven architecture) approach and the DEVS (Discrete Event System Specification) formalism. Platform independent models (PIM) are used to describe the vehicles and its interaction;then, theses models are traduced to platform-specific models (PSMs) in Matlab-Simulink, Java and other languages. DEVS formalism is designed to describe discrete events model, so in order to use continuous time models the second order quantified states simulation (QSS2) is proposed. This method is applied to an autonomous radio controlled hovercraft and its low level tracking controller. Copyright © 2007 IFAC.

The advancement of new technologies in Virtual Reality (VR) allows us to build virtual sports training systems. These systems generally imply videos or computer animations for training demonstrations. VR sports training systems can be used at any time and location. This way, the user can play the sport even at night regardless of weather conditions and can also train or compete alongside other remote users. The virtual sports training system can be used also to help patients suffering from stroke or paraplegia, and can be used in medical rehabilitation. Microsoft Kinect V2 sensor with its great features, like face and body tracking, body gesture, and others, extends the use of virtual reality in different kinds of applications. In this paper, we used the Kinect v2 sensor to design and build a real-time VR sports training system. The system displays in a 3D avatar, simple and complex exercises, captures and records the trainee movements in real-time, highlighting wrong movements and helping the trainee to correct his actions. © 2016, Politechnica University of Bucharest.

In the last years, privacy has been a debated topic since the approval of the European GDPR. People have become more aware of the information gathered by the applications they are using often. Many of them require specific accuracy that may not necessarily need. For instance, weather-based services do not need the exact user location, since the weather is almost the same in a city. This paper focuses on location obfuscation techniques for a user moving in a city. Our solution provides a fake path, based on the real locations and we test it against state-of-the-art attacks to prove its resistance. © 2021, Politechnica University of Bucharest.
