Despite the fact that numerous studies have indicated that vehicular networks are vulnerable to external and internal attacks, very little effort has been expended in safeguarding communications both between elements within the vehicle and between the vehicle and the outside world. In this paper we present a mechanism that allows communications policy (essentially who can talk with whom and the security...
This paper presents a detailed, systematic procedure for developing a Micro Aerial Vehicle (MAV), which is capable of autonomous flight in GPS-denied environments. This MAV is designed for a gross weight of 490 g and flight endurance of 8 minutes. The hardware structure (including the sensors, processors, and mechanical components), the software architecture (including operating system, navigation,...
In recent years a number of organizations have experimented control systems for monitoring the environmental parameters of complex buildings, with the goal of improving well-being, optimizing management costs. These solutions are often characterized by sophisticated, costly technologies that allow to monitor the situation even from remote desks, take proper actions whenever any parameter fails to...
In normal conversation, the meanings of data, information and knowledge can often be used interchangeably. At some level of approximation, these three terms are near enough the same. In the domain of computing and in particular the topic known as artificial intelligence, to accept this generalisation is to lose some resolution in a plausible model of the origin of thought. This paper offers an interpretation...
For engine equipped with dual switch-type oxygen sensors upstream and downstream of the Three-Way Catalyst (TWC), an innovative dual-loop control model of excess air ratio is proposed here. The front oxygen sensor is used to perform PI feedback control of the closed-loop control factor that makes λ ripple periodically in the vicinity of 1. The rear sensor is used to monitor and correct the λ drift...
The most popular method in remote data reading from sensors and meters is the time-driven scheme. However, event-driven schemes seem more efficient, as they reduce the number of samples as well as energy consumption, while achieving the same ability of reconstruction of real continuous waveform from discrete samples with the same accuracy. Even greater benefits can be achieved using event-driven with...
The paper presents a study on the opportunities offered by ICT for improving the efficiency of the generation and distribution system of a small island. The island taken into consideration is the Italian Lampedusa island. In the paper, the power distribution system of the island is described and the summer and winter daily load profiles are examined in order to define the more suitable control actions...
The Wireless Network Control System (WNCS) is a new field that merges between wireless sensor network (WSN) and motor control system, this merge has all the advantages of the two fields. But on the other side, will create a new challenge because it accumulates the disadvantages of both. In these systems, sensors and actuators are connected to the controller by a wireless network that presents an additional...
This paper deals with implementation of feedback controllers on embedded platforms and investigates the trade-off between Quality-of-Control (QoC) and resource utilization. In particular, we consider a setting where the embedded platform executes multiple applications including the control application under consideration. Such a setting is common in domains like automotive where consolidation of several...
This paper suggests a Fuzzy logic technique for designing the control system for the movement of the shoulder joint for prosthetic arm having two degrees of freedom. FIS GUI in MATLAB & Simulink software is used for this objective. The main objective of this paper is to obtain movement of the shoulder joint in intermediate positions using Mamdani fuzzy control logic. The two inputs used in this...
This paper describes the objectives and operating principles of a centralized distribution automation system (DAS) developed for the underground distribution system at Texas A&M University. The DAS detects electric faults based on information from fault indicators and automatically reconfigures the distribution system topology to isolate faulted sections and restore service to the maximum number...
This paper provides an active proposal for the establishment of an industrial control laboratory at an academic institution level. The laboratory is mainly intended for teaching undergraduate and postgraduate students who are majoring in the areas of industrial control and mechatronics programs, respectively. Further services this laboratory could provide are to conduct seminars and workshops for...
Over the last decade, there has been a trend where water utility companies aim to make water distribution networks more intelligent in order to improve their quality of service, reduce water waste, minimize maintenance costs etc., by incorporating IoT technologies. Current state of the art solutions use expensive power hungry deployments to monitor and transmit water network states periodically in...
Data analytics services are on the rise, fostered byan increasing number of wearables and industrial sensors whichare connected over the Internet. As a result, users who want totake advantage of these services are confronted with the challengeof keeping their private data and business secrets secure, whilestill providing the information required for the analytics serviceto operate. Traditional access...
Droop control techniques reported in the literature mainly use compensator based multi-loop feedback structure. To tune these compensators either trial method or inverter average model based complex compensator design method is used. It is cumbersome to tune these compensators especially when large number of inverters having different power ratings are present in the system. In this paper, two novel...
The problems of reliable signal transmission for condition monitoring of power equipment in the energy sector during the technical diagnostics are considered. The principles of the combined coding to ensure a high level of reliability of the systems of technical diagnostics are suggested. The technique for calculating the reliability level for the information signals is represented n this paper.
The method of electromechanical system of electric bridge crane with asynchronous motors modeling, which provides a skew correction and lateral displacement of the crane with high speed and accuracy, is presented. Results of modeling are shown. The direct torque control system is applied to control asynchronous motors. Four contactless distance sensors are used to analyze the position of the crane...
Traffic congestion in large cities became a huge problem, which can lead to a lot of losses especially at the human and material levels. This paper proposes a decentralized model based on multi-agent systems (MAS) and complex event processing (CEP). The new control scheme aims to improve green light time in order to reduce the average waiting time of vehicles in front of the traffic light, especially...
Exhaustive test of complex and autonomous software systems is intractable and cost prohibitive, however incorporating formal methods analysis throughout the system design process could provide a means to identify faults as they are introduced and drastically reduce the overall system development cost. In this research, formal methods, such as model checking and limited theorem proving, are applied...
Water Distribution Networks (WDN) are the infrastructures responsible for delivering drinking water to consumers. The effective monitoring and control of these systems is of vital importance since malfunction may significantly affect the health, safety, security and/or economic well-being of people. The advancements in coupling WDN with the ICT infrastructure, combined with the more recent introduction...
