Software Defined Networks (SDNs) provides a separation between the control plane and the forwarding plane of networks. The software implementation of the control plane and the built in data collection mechanisms of the OpenFlow protocol promise to be excellent tools to implement Machine Learning (ML) network control applications. A first step in that direction is to understand the type of data that...
This paper assesses the performance of actual PRIME v1.3.6 and PRIME v1.4 systems when used for Smart Metering applications. The analysis is performed at the application level using the DLMS/COSEM stack. Hence, it considers performance indicators that are of practical interest for distribution system operators, such as the availability and the average time needed to read the energy load profile of...
Service Function Chaining (SFC) defines the concept of linking ordered Service Functions (SFs) through network technologies to support specific application requirements. SFC exploits Software Defined Networking (SDN) and Network Function Virtualization (NFV) technologies to achieve the creation, modification and deletion of SFC in a cost efficient and rapid way. However, during the runtime phase,...
Electrical current-voltage characteristics of sputtered ZrO2 thin films showing resistance change were examined in this study. The conduction and switching currents were compared on samples with top electrode of 150, 250, and 350 μm in diameter. The size independence of current magnitude implied the presence of an uneven filamentary path over the electrode area. The effect of current compliance was...
We present a triple-mode energy-harvesting power management unit (PMU) that interfaces a photovoltaic (PV) cell and delivers a regulated supply (VLoad) of 0.45V while storing remaining energy in a 3V rechargeable battery. The objective is to maximize the end-to-end conversion efficiency of the PMU against the variabilities of harvested energy and load power dissipation. Specifically, it uses an intermediate...
The smartphone market and the technology of mobile networking have been quite mature. Undoubtedly, smartphones have become an essential communicative tool in people's daily life. The rapid prevalence of smartphones can be attributed to a variety of factors. The mobile operating system (mobile OS), the so-called mobile platform, is definitely the most crucial factor. To probe into potential factors...
A low-input-voltage, highly efficient single-inductor-dual-output (SIDO) boost converter fabricated in 0.18 μm CMOS process is presented for thermoelectric energy harvesting. Two key technologies are implemented to accept input voltage down to 20 mV and to achieve 69 % conversion efficiency at 100 mV, which is the highest conversion efficiency reported to date for such a device. The first key is a...
The proposed system is using low-cost Arduino MEGA 2560 Development Board, synthesizing with PLC module, facilitated with QPSK modulating capability. A generic R-type fire alarm system is hereafter constructed, with a master-slave architecture connecting to fire sensors. No extra modification/rehabilitation is needed for those old buildings because the proposed fire alarm system is mounted on buildings'...
Dependable Network-on-Chips (NoCs) are crucial for the design of recent large scale embedded systems in high-end consumer electronics products. A new NoC architecture named extended 2D mesh NoC (E2DM-NoC) has been proposed in the previous study. The E2DM-NoC is shown to be effective in the reduction of routing rules and communication latency; however, its implementation and performance have not fully...
When the Great East Japan Earthquake occurred in 2011, telephone and Internet could not be used in many cases. To achieve network availability in disaster situations, we propose the traffic control system based on SNS information. In order to utilize the data of packet payload obtained from SNS, deeply programmable network (DPN), which is extending SDN as implementing programmable data plane and API...
This paper introduces a simple and effective model order reduction approach based on singular value decomposition (SVD) and aimed to electromagnetic transient (EMT) analysis. The proposed approach initially adopts a rational approximation obtained by the vector fitting (VF) software tool for an arbitrary frequency range. Then, it applies SVD-based truncation separately to low-frequency range and to...
Integration of renewable energy in residential applications is one of the most promising options to reduce the impact of human activities on the environment. Residential loads are AC loads with high variations generating low-frequency ripples that can harm the sources especially the fuel cell. This paper investigates the use of a neural network algorithm to control a power converter for fuel cell...
This paper proposes a new centralized control scheme for automatic back-feed service restoration in distribution systems with high penetration of distributed generation (DG). The proposed restoration algorithm introduces three types of power transfer between the tied adjacent feeders during the restoration process: load transfer, DG transfer and a combination of load/DG transfer. Another feature of...
Mutation testing is considered as one of the most powerful testing methods. It operates by asking testers to design tests that reveal a set of mutants, which are purpose-made injected defects. Evidently, the strength of the method strongly depends on the used mutants. However, this dependence raises concerns regarding the mutation testing practice that is implemented by existing tools. Thus, it is...
Being a new player in a multiplayer game is not an easy experience. If the game requires coordinated team play for success, an inexperienced player can receive a high amount of abuse because of what others view as bad plays. While the companies try to alleviate this problem by focusing on the offenders, we present another approach that can also help in decreasing toxic behavior. In our paper we introduce...
In nature, the DC-DC converter deals with high switching phenomenon that contributes to the higher conduction losses. Its operation conventionally associated with PI/PID controller in order to meet the desired output. To increase the DC-DC converter performance, an advanced controller has been proposed. However, it is deals with complex algorithm that made the controller cost higher. In this paper,...
This study considers offline identification of switched linear MIMO systems using measurements from their inputs and outputs. This is a class of non-convex optimization and ill-posed problems. To convert this optimization into a binary integer programming problem, the proposed approach assumes that the number of switches among the subsystems is upper-bounded. The state-space realization of each sub-system...
While autonomous capabilities have proliferated across a wide range of commercial and domestic applications, some tasks require intermittent aid from a human operator. Guaranteeing the safety of these intermittently-teleoperated systems requires stability guarantees that hold in the presence of switching. In this paper, we consider the problem of controlling a robotic vehicle using both a human controller...
In our previous study, a piecewise-linear particle swarm optimizer (PPSO) has been proposed. The dynamics of each particle in PPSO can be controlled by two thresholds for convergence and divergence modes. Each threshold can be determined by the particle's trajectory and the system parameters. However, the conditions of these thresholds for finding desired solutions have not been clarified. In this...
Particle swarm optimization (PSO) has been proven to be a simple yet effective algorithm for searching the optimal solutions of objective functions. The main advantage of PSO is its simplicity, but it easily gets stuck in local optima. In order to remain the original merit and raise its performance, a novel idea is proposed in this paper, which selects the best model of PSO based on the previous performance...
