Complexity in System on a Chip (SoC) design is rapidly escalating with the advent of more advanced nodes and the ability to integrate 100's of cores on a single die. This highlights the need to understand the power consumption of the device in the early architectural phases of SoC design. The Power Analysis tooling, centered on Network on a chip, and developed as part of this project allows for quick...
Because of some reasons such as machining error and assembly clearance, the loading device will produce kinematic error during movement. While kinematic error will have a great significance on the position accuracy of the loading device. For the above reasons, firstly, the topological structure of the loading device was described based on lower body arrays. The kinematic error matrices of adjacent...
A novel deployable array mechanism is proposed in this paper which provides a new concept for the future large SAR antenna for a spacecraft. This deployable array mechanism, which is composed by several main array panels and associate array panels, is able to expand in two dimensions with only one degree of freedom. The structure and the skeleton of the novel deployable mechanism are described at...
An equipment model and network topology of the concentrated meter reading for LV (low voltage) district, including the power line model and the metering unit model based on the composition and characteristics of the concentrated meter reading for LV district, as well as the device attributes affecting the district structure are proposed in this study. The topology analysis is provided, which facilitates...
In recent years, dictionary learning (DL) has shown significant potential in various classification tasks. However, most of previous works aim to learn a synthesis dictionary. The other major category of DL-analysis dictionary learning has not been fully exploited yet. This paper proposes a novel DL method, named Topology Preserving Dictionary Learning (TPDL). First, we propose a triplet-constraint-based...
As the ubiquitous phenomena in various fields, increasing coupling and interactions of network have raised a novel topic: network of networks. The supernetwork is a promising tool modeling such hierarchical structure of networks. This paper attempts to present a comprehensive survey on the state-of-the-art of this topic. Deficiencies of present research and prospects are proposed.
In wireless fading channels, the path-loss exponent (PLE) is one of the most fundamental parameters to characterize the channel propagation. It has an important impact on the received signal strength (RSS)-based localization in wireless sensor networks (WSN). On the other hand, the communication range of a sensor in a WSN depends on the transmission power and on the environment (outdoor or indoor)...
Minutiae is widely used in fingerprint recognition, however, single minutiae feature is still unable to cover the influences from the acquisition process. Interferes such as dirty fingers, uncertain pressing position and so on can easily affect the accuracy. In order to improve this situation, we propose a new feature model called local minutiae topological. Unlike other methods, the proposed model...
Transmission Expansion Planning (TEP) is an optimization problem that has a non-convex and combinatorial search space so that several solution algorithms may converge to local optima. Therefore, many works have been proposed to solve the TEP problem considering its relaxation or reducing its search space. In any case, relaxation and reduction approaches should not compromise the quality of the final...
Computer planning and simulation of power systems requires system components to be represented mathematically. A method for building a dynamic phasor model of an Interline Dynamic Voltage Restorer (IDVR) is presented, and the resulting model is tested in a simple radial distribution system. Mathematical analysis is carried out for each individual component of the IDVR as modular models, which are...
Using Network Functions Visualization (NFV), network functionality can be virtualized and deployed on generic servers. This increases network flexibility, and makes it possible to allocate network services in multiple locations throughout the network. Virtual Network Functions Placement (VNF-P) solves the problem of where network functions must be allocated within the network, and makes use of the...
The noise induced by variations in power supply adversely effects System-on-chip (SoC) performance and these effects could be understood through modelling and analysis of Power Distribution Network (PDN). This paper presents modelling of PDN by incorporation of BGR and LDO for analyzing the effect of supply induced noise on the PDN performance. The effect of Simultaneous Switching Noise (SSN) resulting...
Online Social Networks (OSNs) is taking over television and newspapers, to be the dominant information dissemination option. The growing involvement of individuals create the situation that colliding, even contradicting information coexist and propagate in the same network, which gives rise to an interesting question: how will the conflicting information propagate? To answer this question, the propagation...
Wireless Sensor Network is the set of homogeneous or heterogeneous sensor nodes; those can sense the data from different sensing areas of the network. There are different routing protocols exist for find the efficient route to transmits the data from source to destination. The performance of the routing protocols depends of the various factors in the network like packets size, types of signals, movement...
Actual trends of networks-on-chip research and known approaches to their modeling are considered. The characteristics of analytic and high-/low-level simulation are given. The programming language SystemC as an alternative solution to create models of networks-on-chip is proposed, and SystemC models speed increase methodic is observed.
The average-value model (AVM) of the modular multilevel converters (MMCs) is the simplified one for the average response of switching devices, converters and control. The effect of sub-module capacitor voltage ripple on the MMC dynamic behavior is explored and an accurate average-value model of MMCs is established. Based on the proposed AVM, the equivalent impedances of the DC and AC sides in the...
The Routing Protocol for Low power and lossy network (RPL) is recommended by Internet Engineering Task force (IETF) for IPv6 based Low Power Personal Area Network (6LoWPAN). RPL is a proactive routing protocol for Internet of Things (IoT) that has applications in smart homes, smart cities and smart world. RPL creates a Directed Acyclic Graph (DAG) of the network topology. Rank in a primitive construct...
Multilevel inverters acts as a promising solution for medium voltage, high power applications due to their modularity and reduced voltage stress across the switches. Cascaded H Bridge Multilevel Inverters (CHB-MLI) are being considered as the best choice for grid connected Photovoltaic (PV) systems since they require several sources on the DC side. By means of MLI's, high quality output with less...
