Design and Development of a Low Cost Ubiquitous Tracking System

引用

Procedia computer science 2014年 34卷 220-227页

作者： M. Behzad A. Sana M.A. Khan Z. Walayat U. Qasim Z.A. Khan N.

In this paper, design and development of a ubiquitous tracking system is proposed, in which vehicles are tracked and controlled using the prevailing cellular technologies. The system contains a GPS receiver and a GSM modem interfaced with a microcontroller. To track any vehicle, the vehicle's owner has to send an SMS to the tracking system installed inside the vehicle. Upon receiving the SMS, the microcontroller takes the current location's longitude and latitude coordinates from GPS receiver, packs it into an SMS and sends it to the owner and on a web server using GSM modem. When the web server receives the SMS containing vehicles coordinates, it will show location of the vehicle on Google Maps. For android users, the location is also displayed on an android application. In case of vehicle theft, the owner is able to turn off the main ignition switch, check status and speed of the vehicle simply by sending an SMS. The system is also equipped with a special security button for parked vehicles. By turning the button ON, the system will come in ACTIVE mode and will keep a special check on the vehicle's movement meanwhile performing the normal tasks. If the system senses any movement of vehicle during the ACTIVE mode, it will turn the main ignition OFF and will inform the owner immediately be sending 5 SMSs. Record of the vehicle's movement will be continuously managed on the web server where each owner will have vehicle's account. We have used a wide number of technologies including, but not limited to, Global Positioning System (GPS), Global System for Mobile Communication (GSM) and Microcontroller.

Internet of Things based health care systems play a significant role in Information and Communication Technologies and has contribution in development of medical information systems. The developing of IoT-based health care systems must ensure and increase the safety of patients, the quality of life and other health care activities. The tracking, tracing and monitoring of patients and health care actors activities are challenging research directions. In this paper we propose a general architecture of a health care system for monitoring of patients at risk in smart Intensive Care Units. The system advices and alerts in real time the doctors/medical assistants about the changing of vital parameters or the movement of the patients and also about important changes in environmental parameters, in order to take preventive measures.

High-order continuum kinetic method for modeling plasma dynamics in phase space

引用

AIP Conference Proceedings 2014年第1期1639卷 146-149页

作者： G. V. Vogman P. Colella U. Shumlak Applied Science & Technology Program University of California Berkeley Berkeley CA 94720 USA Computational Research Division Lawrence Berkeley National Laboratory Berkeley CA 94720 USA and Department of Electrical Engineering & Computer Science University of California Berkeley CA 94720 USA Aerospace & Energetic Research Program University of Washington Seattle WA 98195 USA

Continuum methods offer a high-fidelity means of simulating plasma kinetics. While computationally intensive, these methods are advantageous because they can be cast in conservation-law form, are not susceptible to noise, and can be implemented using high-order numerical methods. Advances in continuum method capabilities for modeling kinetic phenomena in plasmas require the development of validation tools in higher dimensional phase space and an ability to handle non-cartesian geometries. To that end, a new benchmark for validating Vlasov-Poisson simulations in 3D (x,vx,vy) is presented [1]. The benchmark is based on the Dory-Guest-Harris instability and is successfully used to validate a continuum finite volume algorithm. To address challenges associated with non-cartesian geometries, unique features of cylindrical phase space coordinates are described. Preliminary results of continuum kinetic simulations in 4D (r,z,vr,vz) phase space are presented.

Vehicular networks will play an important role in future smart cities. Connected vehicles will be able to provide entertainment content to their users in order to make traffic situations more enjoyable. However, the amount of bandwidth available to the vehicles may not be enough to satisfy all of them. In this case, we can say that a conflict of interest occurred and then must the solved as fair as possible. In this work, we propose a solution to solve this kind of collective conflict. Our solution balances users' satisfaction with resources consumption as it is capable of choosing the most adequate resolution algorithm based on the current application's situation. The results showed that with our solution it was possible to achieve adequate satisfaction levels, with low response time and controlled network usage.

The paper is aimed at the definition of an efficient control framework for freeway systems. To this end, a Model Predictive Control scheme based on the cell transmission model is adopted in which the considered control action refers to ramp metering. Two major aspects characterize the paper. First, the prediction model is formulated as a mixed logical dynamical system (i.e. it is described by linear dynamic equations and linear inequalities in which both real and integer variables are involved) in order to obtain a finite-horizon optimal control problem with the structure of a mixed-integer quadratic programming problem. In such a problem the objective function quadratically penalizes the deviation of the state variables from a specific equilibrium point. Secondly, an event-triggered scheme is used to further reduce the computational load of the control scheme making it more adequate for real applications. Numerical results based on data coming from a real case study relevant to Grenoble South Ring are also presented and discussed. © 2013 EUCA.

Mathematical Model and Fabrication of Multi-Layer Electrochemical Glucose Sensors

引用

International Journal of High Speed Electronics and Systems 2015年第3N04期24卷

作者： Robert A. Croce, Jr. Santhisagar Vaddiraju Allen Legassey Fotios Papadimitrakopoulos Faquir C. Jain Biorasis Inc. 1392 Storrs Road Storrs CT 06269 USA Department of Electrical & Computer Engineering University of Connecticut Storrs CT 06269 USA Nanomaterials Optoelectronics Laboratory Polymer Program Institute of Materials Science University of Connecticut Storrs CT 06269 USA Department of Chemistry University of Connecticut Storrs CT 06269 USA

The design and fabrication of multi-layer amperometric electrochemical glucose sensors is dependent upon the diffusional kinetics of the chemical/biochemical species which contribute to the sensor’s response. Considerable effort has been carried out to coat the working electrode with appropriate glucose flux-limiting membranes which is pertinent for superior in vivo performance, and hence requires a careful understanding of the participating species within the sensor cross-sectional architecture. This contribution reports the computational modeling of Clark’s first generation amperometric glucose sensor coated with an electro-polymerized glucose oxidase (GOx) layer along with a layer of polyurethane (PU) employed to reduce the glucose-influx in order to generate linear operation over the normal physiological glucose range in vivo . The model was programmed using MATLAB and utilizes the finite-difference method for the solution to the enzymatic reaction-based diffusion equations. Additionally, experimental devices were fabricated, tested and compared with the simulated results. The simulation of these devices have been shown to align well with experimentally fabricated devices in terms of amperometric current density. The increase in device linearity with the addition of the outer glucose-flux limiting PU membrane corroborate our experimental findings reported in this study which can be used as a powerful analytical tool in designing high–performance next generation implantable glucose sensors.
