Fleet management systems have been widely used in the maritime industry. Traditional fleet management systems focus on the whole vessel/ship. With the emergence of the Internet of Things and new smart technologies, smart fleet management systems are now embedded with greater power in comparison with traditional solutions, e.g. can be used to monitor the performance, status and behaviour of not just...
Open source microcontroller (MCU) boards have made significant inroads towards classroom teaching over the last decade. Many programs have already switched from the traditional educational boards to, for example Arduino products, due to their low costs, easy to use, flexibility, and wide adoption in both consumer and industrial applications. However, comparing with their commercial counterparts, open...
Cloud computing and cloud storage systems are being used more and more in a variety of domains, from everyday user applications like healthcare monitoring systems and intelligent buildings to military devices. The deployment of these frameworks also enables modern control and automation paradigms found in cyber-physical systems and Industry 4.0. Driven by exponential decreases in computing and storage...
Freezing of gait is considered a clinical problem in Parkinson's disease, due to its episodic nature, heterogeneous manifestation, and drug resistance. Automatic and objective assessment of freezing of gait may help to increase clinical knowledge and to manage its effects on daily living. In this paper, a fuzzy logic algorithm is presented and tested in real-time on a smartphone.
Electronic Control Unit is an electronic system which controls different engine parameters for optimized performance. In SI engine, ECU controls the Injector opening timing and spark timing at different engine speed and load. Many ECU functionalities like Idle control, Cold start control, AFR control, Altitude correction etc. are explained in this paper which are helpful/main control strategies while...
In electronic control of internal combustion engine several sensors are used in the intake and exhaust path to acquire information about pressure, temperature, air mass flow, actuator position etc., for executing optimum control of the desired engine operation. The pressure signals sensed by these sensors are found to have pulsations due to construction and operation of the engine induced during intake...
This paper reviews the technique of electrostatic monitoring. Over the past twenty years, the technique of electrostatic monitoring has been developed and applied to aircraft and engine condition monitoring in a wide range of components. The first successful application was to gas turbine engines where it was used to detect the presence of foreign debris in the gas path. Subsequent research has shown...
Data integration is a technique used to combine different sources of data together to provide an unified view among them. MOMIS[1] is an open-source data integration framework developed by the DBGroup1. The goal of our work is to make MOMIS be able to scale-out as the input data sources increase without introducing noticeable performance penalty. In particular, we present a full outer join method...
Cognitive Radios are secondary radio systems which can use the vacant bands of a Primary radio for communication. Cognitive radios are reconfigurable radios with signal processing and Machine learning capabilities. The spectrum usage is controlled by different spectrum regulatory authorities and agencies. Majority of the agencies are following a static spectrum allocation technique and CRs are looking...
The Manet or Mobile Ad-Hoc Networks are capable of forming wireless networks with different topologies. The radios which form the network uses a specific band, data rate and frequency. The paper focuses on the implementation of intelligent Mobile Ad-hoc NETwork (iMANET) in which wireless networks are established using reconfigurable radios so that intelligent networks can be formed. The nodes involved...
Several thousand sensors hard-wired to data acquisition units may be used to instrument a gas turbine engine during its development phase. This process of hard-wiring is time-consuming, expensive, and inflexible. A wireless sensor network (WSN) is proposed as a solution for selectively replacing wired sensors with wireless sensors and for adding new sensors. The WSN shall operate between the engine...
In this paper, a guaranteed cost controller is designed for a mixed-flow two-spool turbofan engine to ensure its dynamical performance under networked conditions. The linear state-space engine model is first identified, based on which a networked engine control (NEC) system is established where the transmission delay and the packet dropout are considered simultaneously. Then the networked guaranteed...
Coping with emergency situations requires effective and prompt decision-making under constantly changing situations. The deployment of various kinds of sensors makes it possible to acquire vast amounts of information. At present, however, most information processing is not automated; therefore, the quality of decision-making depends heavily on the capacities of the decision maker. To solve this problem,...
Internet of Things (IoT) applications like smart cars, smart cities and wearables are becoming widespread and are the future of the Internet. One of the major challenges for IoT applications is efficiently processing, storing and analyzing the continuous stream of incoming data from a large number of connected sensors. We propose a multi-representation based data processing architecture for IoT applications...
Military operators require relevant information from Intelligence, Surveillance and Reconnaissance (ISR) assets to make timely decisions and to issue effective responses to mission events. Today's sensing and Command and Control (C2) systems blindly collect and pass all available ISR data, which results in data overload that increases demand for communications bandwidth and processing power, with...
Detecting students' attention in class provides key information to teachers to capture and retain students' attention. Traditionally, such information is collected manually by human observers. Wearable devices, which have received a lot of attention recently, are rarely discussed in this field. In view of this, we propose a multimodal system which integrates a head-motion module, a pen-motion module,...
Smart Cities make use of complex utility infrastructure systems such as water distribution. These infrastructures have raised management costs due to improper resource utilization and maintenance or aging infrastructure. New innovative information systems are essential to overcome these issues. Due to the continuous growth of infrastructure systems of smart cities in scope and scale, led to the usage...
CO2 emissions from transport constitutes a large, and growing, part of the total carbon emissions. We present a model to estimate CO2 emissions from passenger cars on basis of GPS and accelerometer data gathered from the driver's or passengers' smartphone apps. As part of an experiment to establish ground truth, a method for measuring fuel consumption without instrumenting vehicles is presented. As...
The aero-engine gas path fault is the important aero-engine fault and has high frequency. This fault must be found timely and solved as early as possible to make sure the normal work of aero-engine and the safe flight of the airplane. The burn fragments fault is a common fault aero-engine gas path fault. The special aero-engine gas path fault simulation test system is necessary if we want to study...
In this work, a data-driven fault diagnosis and estimation scheme is proposed and developed specifically for aircraft gas turbine engine actuator and sensors.
