In this paper, we discuss about how to orchestrate service function chaining (SFC) with distributed cloud VMs (virtual machines). By introducing an automated tool for graph-based SFC over cloud-based infrastructure, we attempt to satisfy service realization challenges such as large-scale support and underlay-aware improvement.
As education and technology merge, the diversity of teaching and learning methods expand even more. Virtual labs are a set of web applications containing learning materials that compliment the various courses in an Engineering curriculum. The primary intent of the virtual labs is to provide in-lab experience to their users even when the physical lab infrastructure is not available. In this paper,...
The article is focused on problematic of the middle size wheeled 6×6 UGV development (approx. 1100kg), lessons learned, achieved results and its system integration in the digitized battlefield. Based on previous experiences with UGV systems, there were identified fundamental factors of tactical and technological requirements, which converge to a set of priorities, including some (routine) processes...
In this paper, a linear control technique based on a PID controller, which is the most used controller type in the industrial applications, is proposed for the angular position control of fan and plate system that has a nonlinear characteristic. Although the system is nonlinear, in the experimental studies, it is observed that for any small region in which the system can be considered as linear, the...
When disproving termination using known techniques (e.g. recurrence sets), abstractions that overapproximate the program's transition relation are unsound. In this paper we introduce live abstractions, a natural class of abstractions that can be combined with the recent concept of closed recurrence sets to soundly disprove termination. To demonstrate the practical usefulness of this new approach we...
This paper presents the design and implementation of a didactic and flexible training module that contributes to the theoretical and practical development of academic training, this through a mechanical structure and a software that has the ability to perform multiple laboratory practices in different areas related to microcontrollers, computer vision, automation. The design consist of four blocks;...
It is known as photovoltaic (PV) panels have a low energy efficiency. A solution of increasing energy efficiency consists in use of sunlight concentrating elements equipped with automatic tracking systems. This paper presents aspects of designing an automaton for PV panels tracking system fitted with low sunlight concentrating elements.
Unibral is a program that supports research and education cooperation actions between German and Brazilian universities. This work in progress paper will describe a new version of such an old experience of Unibral, a project between the Federal University of Amazonas and the University of Stuttgart. This edition started in 2013 and joined two institutes related to the electrical and computer engineering...
Consumer products are human-machine systems, and a design of a user interface is an important issue. A user identifies the behaviors of the machine using partial or abstracted information provided by the user interface, and gives a command. If the information is not sufficient for his/her operation, its response to the operation may be different from his/her expected one. Such a situation is called...
Automation testing framework enables the complete automation of the entire testing process in a software development life cycle. This research paper will mainly focus on a new hybrid automation testing framework called GRAFT - Generic & Reusable Automation Framework which supports cross browser testing.
Shenzhen power supply bureau (SZPSB) urgently need a series of methods which can analyze the cause of wireless communication fault and predict wireless communication failure, these methods can facilitate operations staff take the initiative to master the signal status, solve the problem of signal fault in time, and increase the terminal online rate. In this paper, we present a model named GCFPM (Gradient...
Hybrid energy storage system (HESS) can achieve a better overall performance by combining power-type storage and energy-type storage. The combination enables active distribution network (ADN) to regulate power flow and manage energy more economically and realize active control. This paper analyzes the technical characteristics of the HES S to propose a control strategy of HESS applied in ADN at first...
In this paper a platform is developed to facilitate the control of household loads using communication protocols relevant to home automation and substation automation systems. Protection IEDs that support IEC 61850 standard based protocol, universal secondary test gear for relays and a protocol converter are used to realize the protection/automation aspects for substation automation. The retrofitting...
The set coverings problem using mathematical methods in which principles of natural mechanisms of solution-making are proposed. For compact representation of the set covering solution the matrix of boundary requirements is used. This allowed forming the space of solutions in which frameworks the search process which is based on simulation of adaptive ant colony behavior is organized. In comparison...
This paper introduces an improved method of biped walking. We analyse the walking pattern of Robots based on the theories of 3D-LIPM, with special focus on the velocity and acceleration of its center of mass(CoM) when Robot changes its supporting leg. It finds that both velocity and acceleration are discontinuous. To solve the problem, a fifth-degree polynomial curve is inserted and the solutions...
