Service Assurance (SA) is a significant part of Network Function Virtualization (NFV) to enable automated and efficient service delivery from end to end (E2E). In NFV, SA should be integrated into the design and development loop from the beginning. However, it sees slower pace than other NFV management and orchestration (MANO) components. Most of present NFV-SA solutions are partial and do not provide...
Industrial Control Systems (ICS) networks are an increasingly attractive for attackers. The case of 2015 Ukraine cyber attack where hackers abused the ICS system to create a blackout is a good illustration of this interest. However, to achieve physical effects, it is necessary for attackers to embed themselves deep within the target network. So, attackers must protect this investment by using covert...
We consider the problem of inferring the operational status of a reactor facility using measurements from a radiation sensor network deployed around the facility's ventilation off-gas stack. The intensity of stack emissions decays with distance, and the sensor counts or measurements are inherently random with parameters determined by the intensity at the sensor's location. We utilize the measurements...
In this paper we propose oil skimmer monitoring system by user-controlled smart phone IoT(Internet of Things)-specific controller and built in BLE 4.0. The device Hardware of the IoT is the trend of OSHW(Open Source Hardware). This opens up free design content for physical artifacts together spirit with FOSS (Free and Open Source Software). As a result of the derivation of Open-source culture making...
The issues of cable insulation temperature monitoring are one of the topical problems of the electric power engineering industry. One of the most promising researches in this field is the development of techniques for the cable insulation remaining life determination. It can be calculated using the insulation temperature monitoring data and data about other influences that have a significant effect...
Wireless Sensor Networks are deployed in different fields of application to gather data on the monitored environment. The Wireless Body Sensor Network (WBSN) is a wireless sensor network designed to monitor a human body vital and environment parameters. The design and development of such WBSN systems for health monitoring have been motivated by costly healthcare and propelled by the development of...
Hajj is a ritual practice where millions of pilgrims arrive in a limited area and required to transfer through dedicated paths to several locations. Congestions and overcrowded have been one of the biggest challenges to the authorities, and hence, encourages researchers to proposed practical solutions to preventing congestions and their consequences from happening. In this paper, we propose an Expert...
Cloud computing technology is gaining rapid growth in popularity. Mostly it is web based service and some private modules are built on intranet or virtual private network. Network security is a major concern for both cloud users and hosts of data centers. In addition to this, clients are also concerned about the infrastructure and service quality offered by cloud service providers. Cloud service providers...
In order to meet various requirements of the 5th generation (5G) communication system, larger amounts of spectrum are required. Television White Space (TVWS) and Licensed-Assisted Access (LAA) can only utilize the specific frequency band as shared frequency and have no mechanism for sharing the other frequency bands to obtain more frequency resources. We have proposed a dynamic frequency-sharing system...
In this work, we demonstrate the alpha prototype for a wearable air quality sensor system. This system will be used to create precise, high-resolution maps of the environment to help individuals with respiratory disease track their response to pollutants, determine when to pre-medicate, or avoid areas with poor air quality altogether. The data from such a map will provide improved accuracy over the...
Highly sensitive device to detect bacteria in blood serum is presented. The device comprises of a microfluidic component and an electronic reader. The microfluidic cassette acts as an enclosed vial. It is filled with the sample after mixing with an indicator dye. Then, it is inserted into a kinetics fluorometer. The rate of the fluorescence increase is proportional to the number of viable cells in...
Telemetrie Sensing Node Network System(TSNNS) is so available to monitor Landslide Disaster(LD) occurred on slopes of mountain and hill. TSNNS consists of three main systems; Local Sensing Node Network System(LSNNS) arranged on the slopes, Cloud System and Host System(HS) at a remote place far from the area of LSNNS. In disaster measurement for landslide, the measuring system needs characteristic...
A clinical decision support system and its components may malfunction due to different reasons. The objective of this work is to develop computational methods that can help us to monitor the system and assure its proper operation by promptly detecting and analyzing changes in its behavior. We develop a new change-point detection method using the Multi-Process Dynamic Linear Model. The experiments...
In this study, we use wearable devices to monitor the health and physiological indicators of the elderly, and analyze the effects of the elderly's walking steps and sleep as the measurable health and physiological indexes. Eighteen cases of the elderly who received health management services are selected. We establish the generalized linear mixed model, and Pearson correlation analysis result shows...
The emergence of Internet of Things (IoT) promises to solve a wide range of issues that are related to the management of existing resources and delivery of new human-centric services in urban environments. IoT is being harnessed to benefit a wide range of Smart City applications including (but not limited to) holistic urban planning, tracking of city wide services, enhancing public transportation,...
Gait velocity has been considered the sixth vital sign. It can not only be used to estimate the survival rate of the elderly but also to predict the tendency of falling. Unfortunately, gait velocity is required to be measured using specially designed walk path with minimal walk distance, which has to be conducted at clinics or health institutes. Wearable tracking services using accelerometer or inertial...
To reduce conservative timing margin, many timing-error detection techniques by monitoring selected critical paths had been proposed. However, traditional adaptive methods incur significant area overheads and cannot prevent the error that is forming in the current clock cycle. In this paper, a low-overhead Transition-Detector (TD) with a 9-transistor current sensing circuit is proposed. TDs are inserted...
This work proposes an ANN based method for fetal heart rate monitoring. Various measurements are taken and given as input to the ANN based classifier to detect fetal health such as ‘Normal’, ‘Suspect’ and ‘Pathologic’. All the design and simulation works are carried out with MATLAB software. ANN based classifier is trained with data from various recordings of cardiotocography. After the network is...
Filtering of ECG signal is an essential step in ECG signal processing and analysis. Since ECG is a low amplitude biosignal, it is easily corrupted by external noises, and by the presence of other biosignals. The aim of filtering is to remove unwanted noise while preserving important characteristics of the signal. Various filtering techniques are available thus choosing the right filter for ECG denoising...
Identifying the most recent heavy hitters, i.e., finding the items with the highest appearances in a high speed data stream is a fundamental problem in real-time stream processing. The requirement of real-time stream applications raises significant challenges to this problem in terms of the processing latency, the space usage and the precision. Traditional schemes leverage the sliding windows based...
