System landscapes within logistical scenarios is highly heterogenic. Adding specific mechanisms, e.g. to support planing, monitoring and analyses for fully electrical powered vehicles, could become a mess or at least a challenge. While our project Smart City Logistic (SCL) is trying to manage this extension for multiple logistic scenarios, other projects want to do comparable system extensions as...
It has been shown that up to 64 percent of personal computers in office buildings are left running during after-hours. Enabling power management options such as sleep mode is a straightforward method to reduce the energy consumption of computers. However, choosing the right timeout can be challenging. A sleep timeout which is too low leads to discomfort, whereas a timeout which is too high results...
Programmable Logic Controllers (PLCs) are specialized computing systems for the control and monitoring of distributed industrial devices. Aiming for a highly connected industrial Internet-of-Things (IoT) ecosystem, PLCopen OPC Unified Architecture (UA) specification has been released. This paper presents the implementation and evaluation of a PLCopen OPC-UA software component for industrial control...
More and more modern applications make use of natural language data, e. g. Information Extraction (IE) or Question Answering (QA) systems. Those application require preprocessing through Natural Language Processing (NLP) pipelines, and the output quality of these applications depends on the output quality of NLP pipelines. If NLP pipelines are applied in different domains, the output quality decreases...
As modern unmanned aerial systems (UAS) continue to expand the frontiers of automation, new challenges to security and thus its safety are emerging. It is now difficult to completely secure modern UAS platforms due to their openness and increasing complexity. We present the VirtualDrone Framework, a software architecture that enables an attack-resilient control of modern UAS. It allows the system...
This paper describes the software architecture and the implementation of a fully operational testbed that demonstrates the benefits of flexible, dynamic resource allocation with virtualized LTE-A nodes. The testbed embodies and specializes the general software architecture devised within the Flex5Gware EU project, and focuses on two intelligent programs: the first one is a Global Scheduler, that coordinates...
In internet of things (IT) environment, a sensor interface device is essential for data collection in wireless sensor network (WSN) system for water quality monitoring (WQM) as the water pollution is a critical issue globally. This paper presents the design of a WSN based reconfigurable smart sensor interface device for WQM system in an IoT environment. The system consists of Field Programmable Gate...
In this article, we evaluate existing open source Phasor Measurement Unit (PMU) and Phasor Data Concentrator (PDC) software systems and benchmark their performance and reliability with various database systems. We also evaluate usability of the PDC systems and to list additional feature for the system. Among two open source PDC software, we found that OpenPDC out performs other PDC software in terms...
This article shows the possibility of using renewable energy sources in order to improve energy efficiency, reduce greenhouse gas emissions and therefore prevent climate change. This article proposes a remote monitoring and control system with interfaces and data collectors. In addition to research, development, testing and use of renewable energies, it is also necessary to measure and track online,...
The abundance of activity trackers and biosignal sensors as well as the evolution of IoT and communication technologies have considerably advanced the concept of Quantified-Self. Nowadays there are several frameworks and applications that realize the concept, focusing though strictly on specific areas, from daily use to professional activities such as sport and healthcare. This work proposes a versatile,...
Measuring and monitoring the bio-parameters of patient is one of effective method to assist doctor during diagnosis and treatment now. This paper presents a research result about using the patient monitor devices in the hospitals today. Since, we proposed and designed a model of a wireless central patient monitoring system for the hospitals in Vietnam. From the single patient monitoring devices, the...
Web Archiving Integration Layer (WAIL) is a desktop application written in Python that integrates Heritrix and OpenWayback. In this work we recreate and extend WAIL from the ground up to facilitate collection-based personal Web archiving. Our new iteration of the software, WAIL-Electron, leverages native Web technologies (e.g., JavaScript, Chromium) using Electron to open new potential for Web archiving...
This paper describes a virtual instrumentation architecture to measure and monitor partial discharges (PD) in high voltage equipment. The system has been successfully applied in the diagnosis of several rotating machines in Brazil. The proposed solution for PD measurement using virtual instrumentation involved defining architecture for the measurement system, the specification of suitable hardware...
This paper addresses requirements from future automotive electronics system concept/design to computing technology or platform filling processing characteristics which will be used in applications of automated driving generation. We cannot completely predict future trends of functionality or application, so it is important to have flexible and scalable computing platform for that generation. The platform...
In this paper, we introduce Kalis, a self-adapting, knowledge-driven expert Intrusion Detection System able to detect attacks in real time across a wide range of IoT systems. Kalis does not require changes to existing IoT software, can monitor a wide variety of protocols, has no performance impact on applications on IoT devices, and enables collaborative security scenarios. Kalis is the first comprehensive...
The crowdsourcing (CS) is a software development practice that increases in the productive sector. This environment is supported by a platform which relates the crowd, the provider, the sponsor and the developer. Microtasks are executed by people, and these are joining in a large project. The teaching of crowdsourcing in undergraduate courses is minimal compared to the teaching of traditional Distributed...
Inside of any organization, the acquisition process of product or service is extremely important and if not done properly can cause uncountable damage. In this way, the software acquisition isn't different and can cause uncountable problems too, like delays in existing contracts or even the dependence on the company contracted to code the product. Thus, the objective of this work is provide a software...
Technical Debt (TD), also known as technical debt design or technical debt code, analyze the consequence that could have a system once it has been designed architecturally, coding or implemented. TD refers to work to be performed rather than software design or coding is considered complete or correct. Static analysis is a technique to identify and analyze software characteristics from source code;...
