The conventional method of testing water quality is to gather samples of water manually and send to the lab to test and analyze. This method is time consuming, wastage of man power, and not economical. The water quality measuring system that we have implemented checks the quality of water in real time through various sensors (one for each parameter: pH, conductivity, temperature) to measure the quality...
Help between peers, intended to positively influence learning, appears as a suitable activity for inquiry learning. While several studies reveal evidence that effective help-seeking and help-giving behaviors can improve learning, virtual and remote laboratories do not provide sufficient support to enable these social interactions. Based on a set of criteria defined from existing literature, we designed...
The number of time that heart beats per one minute we call it as the heart rate or pulse. It is an indicator for monitoring health. In this paper, we present the Burn in Zone: Physical activity real-time heart rate monitoring, a novel model to help people who prefer to have a more physical activity to continue their intention in the long term. We were mainly interested in real-time heart rate monitoring...
Software Defined Networking (SDN) is the key technology for combining networking and Cloud solutions to provide novel applications. SDN offers a number of advantages as the existing resources can be virtualized and orchestrated to provide new services to the end users. Such a technology should be accompanied by powerful mechanisms that ensure the end-to-end quality of service at high levels, thus,...
We design and implement an intelligent advisor system for assisting individuals in changing their physical activity behavior. This system monitors an individual's physical activity and provides personalized, dynamic, pace-based recommendations to help an individual attain his/her activity goal. It adapts to a person's real-life constraints and generates recommendations using data from the individual's...
Pediatric asthma is a prevalent chronic disease condition that can benefit from wireless health systems through constant symptom management. In this paper, we propose a smart watch based wireless health system that incorporates wireless sensing and ecological momentary assessment (EMA) to determine an individual's asthma symptoms. Since asthma is a multifaceted disease, this approach provides individualized...
With the increasingly application of discrete control software in automatic control field, the security and reliability of its behavior becomes even more essential. However, the traditional verification methods are of high complexity and poor flexibility, so the lightweight Runtime Verification becomes an alternative. In this paper, aiming at real-time properties in discrete control software, an improved...
The maintenance of control and instrumentation (C&I) cables is crucial to safety of operating nuclear power plants. Therefore, when an accident occurs, there is a need for an accurate assessment of the impact on the cable's integrity. Unfortunately, most cable diagnostic methods are destructive and real-time assessment of the effect of accidents is not possible. Thus, in this paper, we present...
The increased penetration of uncertain and variable renewable energy presents various resource and operational electric grid challenges 1 . Micro-level (household and small commercial) demand-side grid flexibility could be a cost-effective strategy to integrate high penetrations of wind and solar energy, but literature and field deployments exploring the necessary information and communication technologies...
In order to notify users about potentially unsafe situations and to track mistakes or efficiency performing activities, it is important to monitor the quality of performing an activity and identify the missing/wrong steps. However, the state-of-the-art activity recognition frameworks ignore such details and impose constraints on sensor values, the types of detected activities (no parallel/interleaved/joint...
Network softwarization - through the adoption of Software Defined Networking (SDN), Network Functions Virtualization (NFV) and Cloud-Fog computing technologies - is deeply impacting telecom and ICT industries. This transformation, along with numerous advantages, brings also considerable challenges. In this paper, we discuss the main features of monitoring in the afore-mentioned landscape as well as...
In the Internet of Things (IoT) era, with ubiquitous remote sensing devices and other diverse data sources, nearly everything can forward voluminous data continuously, in real-time, which drives demand to perform real-time analytics on uninterrupted IoT data flows. The typical resultant approach is a cloud-centered architecture providing an analytic service for real-time IoT data processing. However,...
Current networking integrates common "Things" to the Web, creating the Internet of Things (IoT). The considerable number of heterogeneous Things that can be part of an IoT network demands an efficient management of resources. With the advent of Fog computing, some IoT management tasks can be distributed toward the edge of the constrained networks, closer to physical devices. Blockchain protocols...
A very important aspect of personalized healthcare is to continuously monitor an individual’s health using wearable biomedical devices and essentially to analyse and if possible to predict potential health hazards that may prove fatal if not treated in time. The prediction aspect embedded in the system helps in avoiding delays in providing timely medical treatment, even before an individual reaches...
Climate change due to global warming has incredibly contributed potential risk to the agricultural farming system. The collective responsibility to advocate food security and sustaining the farming system is a key issue. While the conventional farming techniques have combated to meet global food demands, however sustaining food security to provide access to safe and nutritious food is at probable...
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...
Deriving deadline and period for update transactions has long been recognized as an important problem in real-time database research. Despite years of active study, the state of the art only focuses on scheduling of update or control transaction separately. In this paper, we study the problem of deriving deadlines for update transactions in co-scheduling environment upon uniprocessor platforms. We...
Software-defined networking (SDN) simplifies the forwarding devices by introducing a centralized controller. The controller calculates routing rules for the whole network and the forwarding devices cache the routing rules. This working process leads to the new-flow attack. When malicious packets with different headers arrive at the network, they are treated as new flows. These useless flows consume...
Hoare monitors are a safe concurrency abstraction built around a monitor with shared state and methods that operate on the shared state. While well-known, they have been little used as a concurrency framework in real-time systems. We describe a Hoare monitor framework called Tower developed for real-time systems programming that targets multiple real-time operating systems. Hoare monitors use coarse-grained...
Dramatic increases in forest fires in Europe as well as worldwide can be observed. Therefore, technical developments to support large scale forest firefighting strategies and management solutions are an international issue in the quest to protect human lives and resources as well as to reduce the negative environmental impact. This article describes an airborne based concept to enable an efficient...
