The article deals with the condition estimation of 6-10 kV cable lines (CL) with impregnated paper insulation (IPI) taking into account their length and operational reliability measures according to failure statistics. The subject under study is urgent because of the lack of reasonable insulation diagnostics of CL. The article theoretically justifies the CL diagnostics with non-destructive methods...
Photoplethysomographic (PPG) signal is crucial for non-invasive monitoring of heart rate. It is acquired by using pulse oximeter that are prone to artifacts. A major application of this technique is monitoring the heart rate during physical exertion. Extraction of heart rate (HR) from the PPG in this case is difficult due to the strong motion related artifacts. This paper proposes an efficient method...
IoT can dramatically improve the quality of life of aged population. In this regard, Ambient Assisted Living (AAL) and Active and Healthy Aging (AHA) are fields with an enormous potential to benefit from the current growth of IoT within our society. We present SAFE-ECH, an innovative intelligent AAL open source system for monitoring nursing homes. SAFE-ECH creates an Ambient Intelligent environment...
Aggressive scaling down of the Cu trace pitch in the redistribution layer (RDL) is needed to meet the design rule for high-density I/O used in advanced packaging. Such a downsized RDL, however, will be vulnerable to voltage and current stresses, in addition to environmental stress. Voltage stress, for example, degrades the reliability of electrical isolation (dielectric strength). This will likely...
Wireless electrocardiographic (ECG) sensor attached to the skin and connected to a smart device via low power Bluetooth technology has been used to record more than 500 hours of ECG data in a German shepherd dog with dilated cardiomyopathy (DCM). Wireless ECG monitoring has been used for a period of 6 months. With the wireless body electrodes, the ECG data were obtained while the dog was resting,...
This paper describes the development of a simple, compact total dissolved salts (TDS) sensor for use in confined sterile environments. It integrates with a microcontroller for monitoring the total nutrient concentration of liquid media used in plant tissue culture. The system is based on the concept of charging a capacitor (C), in series with a resistive probe (R) immersed in the liquid media, and...
The advances in embedded systems and sensor technology have only recently unlocked the potential of wearable ECG monitoring expert systems. So far, the ECG monitoring software solutions that deal with the processing of harnessed ECG data essentially consist of straight-forward desktop applications. Although there are a number of proposed telecardiology concepts, very few of them are capable of replacing...
Odour concentration is measured sensorially, thus needing a human panel, whereas the measurement of odorous compounds is typically based on physical and chemical analysis. Some systems such as electronic noses try to correlate both approaches in order to measure odour instrumentally, which would allow monitoring odour continuously. In the domain of instrumental odour monitoring, e-noses are the main...
This paper proposes a system integrating device manager, IoT Solution, and Business Process Model and Notation (BPMN) tools. With these tools, domain expert can draw the process with specifying how to connect devices all together. Moreover, domain expert can specify what kind of device is needed instead of explicitly specifying which device is needed, which addresses the IoT feature, mobility. This...
Coffee is Rwanda's main source of income, thus improving processing and monitoring has a large potential economical impact, we are introducing low-cost sensor Technology, by utilizing embedded system to monitor coffee washing station processing method and store centers, the system will be reporting the status of PH, moisture, temperature and humidity as basic information to keep the standard quality...
This demo presents a SFC orchestrator that provides intelligent, dynamic and automated VNFs and network deployment over heterogeneous NFV and SDN enabled Cloud environments. The proposed architecture is based on the ETSI NFV reference architecture and TOSCA standards. In this demo, reliable VNF placement and chaining is ensured using the algorithm proposed in [1] “A Link Failure Recovery Algorithm...
E-learning System has become a common constituent unit of web page of any higher education institution. At the Polytechnic Nikola Tesla in Gospic Loomen is established since 2010, a system that is designed in a role of teaching repository for students and for preparation of e-courses for the teachers and students. The aim of this paper is by using descriptive and inferential statistics, and based...
Traceability is an integral part in maintaining global measurement equivalence, thus it is necessary to ensure that it is efficiently yet effectively executed. In fact, traceability is as important as a measurement itself. Traceability is often obtained through calibrating a device at a laboratory or national metrology institute that has an unbroken chain of comparisons with stated uncertainties starting...
As part of the conducted research, methodological guidelines have been justified and drawn up on strategy forming for developing a retail gas station chain of an oil company based on economic value added.
Circular statistics present a new technique to analyse the time patterns of events in the field of cyber security. We apply this technique to analyse incidents of malware infections detected by network monitoring. In particular we are interested in the daily and weekly variations of these events. Based on "live" data provided by Spamhaus, we examine the hypothesis that attacks on four countries...
This paper is about line search for the generalized alternating projections (GAP) method. This method is a generalization of the von Neumann alternating projections method, where instead of alternating projections, relaxed projections are alternated. The method can be interpreted as an averaged iteration of a nonexpansive mapping. Therefore, a recently proposed line search method for such algorithms...
A enhanced principal component analysis (PCA), termed as Two-step PCA (TS-PCA), is proposed to handle the dynamic characteristic of industry processes. Differently from the traditional dynamic PCA (DPCA) using the “time lag shift” structure, TS-PCA adopts a new structure to present the dynamic property in the process data. By using this new structure, TS-PCA can extract the time-uncorrelated components...
The paper presents the impact of connecting Renewable sources to the Smart Grid with regard to improving Power Quality aspects. The impact of integrating renewable sources on Power Quality indices in the grid wes analyzed and the measures for avoiding the negative impact are included in the paper. Challenges coming from the integration of renewables – variability and uncertainty and the correlation...
This paper is focused on the results of the research project simBART. Particular attention is paid on a method for water evaluation in beer production sector. This process, under investigation, can be targeted to small and not industrialised enterprises as well as to those home brewing productions. Experimental analyses are conducted by means of VPeN, a vapour phase e-nose based on a specific sensor...
The complexity of integrated circuits is continuously increasing, leading to a growing demand for methodologies that offer comprehensive mixed-signal verification concepts. However, compared to the highly automated verification methodologies in the digital domain, pre-silicon verification in the analog domain usually implies a substantial amount of manual work and computational effort. In order to...
