Existing tab/window based applications display a static thumbnail of the page or web app representing the onscreen contents of the display area to the user. There is no way for the content developer to specify what needs to be displayed in the tab/window manager, when a certain page or web app goes to the background. The paper presents a new method, where the content provider can specify the contents...
Application-level firewalls filter traffic based on a white list of processes that are allowed to access the network. Although they have a complete overview of the system in which they are executed, they can be easily bypassed by knowledgable attackers. In this paper we present AL-SAFE, a cloud-tailored application-level self-adaptable firewall which combines the high degree of visibility of an application-level...
With the growing interest in Software Defined Networking (SDN) and thanks to the programmability provided by SDN protocols like OpenFlow, network application developers have started implementing solutions to fit corporate needs, like firewalls, load balancers and security services. In this paper, we present a novel solution to answer those needs with usage control policies. We design a policy based...
In this paper, we investigate the design of a water level sensor device that is able to detect and control the level of water in a certain water tank or a similar water storage system. The system firstly senses the amount of water available in the tank by the level detector part and then adjusts the state of the water pump in accordance to the water level information. This electronic design achieves...
A large number of video applications require real-time response. The high-speed video processing then requires a distributed and parallelized framework utilizing all possible computing resources, i.e., both Central Processing Unit (CPU) and Graphics Processing Unit (GPU) at their best. The CPU–GPU collaboration may cause resource imbalance where GPU-based jobs consume less computing resources while...
With the fast proliferation of residential microgrids integrated into the power grid, it is crucial to develop a low cost and high efficiency microgrid central control (MGCC) for promoting the large-scale application of residential microgrids. Considering various users' demand, we develop a novel MGCC based on the multi-level communication model. The MGCC integrates many functional modules, including...
High-performance computing (HPC) is recognized as one of the pillars for further progress in science, industry, medicine, and education. Current HPC systems are being developed to overcome emerging architectural challenges in order to reach Exascale level of performance, projected for the year 2020. The much larger embedded and mobile market allows for rapid development of intellectual property (IP)...
This paper presents the design of a system of faults detection and localization (its acronym FDI) based on a Piecewise Linear Observer implemented in F-16 fixed-wing aircraft under different regimes of flight: stable level wings, level turn, flight constant rising and roll. The scheme FDI based on observers that using to bank of linear observers for residues generation, switched by a switching law,...
In recent years, the rapid development of cloud computing and software-defined networking. Cloud security issues are more important, we hope to use the virtualization technology of cloud to implement vIDS and vFirewall so that we can according to the requirements of tenants dynamically adjust and replace hardware equipment with software to cut down the high cost. This paper proposes and we design...
The recently emerging paradigm of software defined networking (SDN) predominantly employs the control-data plane OpenFlow protocol, offering centralized real-time programmability and monitoring of network devices. Effective SDN based traffic engineering using OpenFlow, particularly in campus networking however, requires sophisticated real-time user traffic visualization solution having minimum management...
This paper explains the design and implementation of a low cost Non-Intrusive Load Monitoring (NILM) system. The system is designed using open source hardware and off-the-shelf components for a cost of below 8 USD. The device identification system makes use of the current-peak signature to uniquely identify devices turned ON at any instance in time. A current sensor is used at the utility service...

The idea is supported by four different Smart Systems, as Smart Home, Smart Agriculture, Smart Campus, and Seat and Study Module of Smart Library. All designs and implementations contains technological components of embedded systems, mobile application development, cloud based services and client side graphical...
This paper presents a low-power area-efficient instrumentation amplifier (IA) for biopotential recording. The proposed IA adopts a resistor-controlled-oscillator (RCO) to change the mid-band gain of the readout circuit for different biomedical applications. The switched-capacitor load of the IA changes with RCO's output frequency, making the gain of IA continuous tunable. Measurement results show...

Window delay line ADCs, digital PID compensator and DPWM with 2nd ΣΔ modulator are utilized in the converter to pursue highly flexible and intelligent power management. Digital Extend PWM control method is proposed...
In this present day Embedded field most of research focused is on Embedded Linux. Our focus in this paper is Sensor Networking and Automation used for domestic and industrial applications. Using Rassberry Pi 2 developing on python editor & cortex processor presents a design and prototype implementation of new home ill automation system that uses WiFi technology as a network infrastructure connecting...
Internet Service Providers (ISPs) are struggling to cope with the growing volume of streaming video traffic in their network, and the problem will only exacerbate as Virtual Reality applications proliferate. To classify and manage bandwidth for video streams, current practise is to either sample traffic for offline analysis or deploy middle-boxes for in-line packet inspection – such solutions are...
According to the specifications in IEEE 1894-2015, a transient process measuring device (TPMD) is developed to be used in the distribution system, and a line selection technique utilizing large pulse current is presented on this basis. When a single-phase grounding fault occurs, the distribution system is able to be instantly switched from grounding with small current to grounding with large pulse...
With the increasing coupling of secondary system components in smart substation, the operation management becomes more and more difficult. This paper proposes a graphical display approach of secondary functional components based on “information-event-function” logics. The displayed layout as well as connection relationship, which is accomplished through automatic graphing, clearly describes the logical...
