Suspended sediment is distributed in rivers of different depths, the content of which is a significant parameter for dynamics of river sediment movement, water conservancy projects, channel regulation, and even for oceanic ecosystems, oil production. A pair of new focused ultrasonic sensors using PZT as the arrays are proposed in this paper, with advantages of small scattering loss and high energy,...
Cross-sectional irregularities such as eccentricity are an important problem for pipe and tubing infrastructure. Recent work by the authors shows that such axially extended pipe irregularities can cause confinement and feature-guiding of lower order ultrasonic guided waves. In this paper, we demonstrate a technique to monitor such irregularities in pipes by detecting the feature-guided waves using...
The traditional piezoelectric ceramic acoustic sensor was improved and applied to in-situ detecting the engineering properties of sediments in the continental slope of the South China Sea successfully. The relationships between the acoustic velocity and engineering geological characteristics of the sediments were analyzed. Furthermore, acoustic velocity by measurement in situ was compared with the...
Vehicular Ad-Hoc Network or VANET are a particular kind of mobile ad-hoc network in which vehicles act as nodes and each vehicles are equipped with communication technology that allows them to exchange information with each other in Vehicle-to-Vehicle communication (V2V) and also with a roadside network infrastructure(Vehicle-to-Roadside Communication — V2R). This paper represents a prototype vehicle...
This paper aims to reduce improper disposal of waste. The system exploits the technical need for Wi-Fi by the general population. The idea is to inspire people to properly dispose of waste. Here the trash bin acts like Wi-Fi hotspot. Once the user puts waste of certain quantity and enters his/her mobile number, the system sends him a SMS containing a OTP to access the Wi-Fi. This can help us to reduce...
The stability of the movement of an Automated Guided Vehicle (AGV) directly affects the safety of the delivered goods. Variation of loads during the delivery process is one of causes of the instability movement of an AGV. This research discusses the design and implementation of the AGV's speed control system to tackle the load and contour variation using Fuzzy Inference System integrated with PID...
we report on ZnO nanorods based acoustic transducer for sound pressure level sensing applications. The sensing element is a circular diaphragm (diameter: 27 mm) of Stainless steel (SS-304L) substrate, which also acts as a bottom electrode for the developed transducer. Prior to synthesis of nanorods, ZnO seed layer (∼100 nm) film was deposited by DC magnetron sputtering technique. ZnO nanorods were...
This paper presents a new technology for designing, simulation, implementation and validation of a driverless vehicle system with the use of the Arduino microcontroller, ultrasonic sensors and stepper motors are integrated to Lyapunov based control scheme. The goal is specifically to develop a driverless vehicle system which is able to move from an initial to target location in an obstacle free environment...
In the proposed system a solution is given to the problem of “Fishermen Tracking their location in the sea”. For this the sea area is divided into three zones namely; safe, intermediate and danger. The boat is allowed to roam anywhere within the safety zone. If the boat reaches the intermediate zone, a buzzer alert is given to the fisherman. If the boat reaches the danger zone, an intimation is given...
In recent years many signal processing applications involving classification, detection, and inference have enjoyed substantial accuracy improvements due to advances in deep learning. At the same time, the “Internet of Things” has become an important class of devices. Although the paradigm of local sensing and remote inference has been very successful (e.g., Apple Siri, Google Now, Microsoft Cortana,...
We propose a unified platform for multiple unmanned aerial vehicles (UAV). Recently, the UAV technology has seen a great development. However, the capability of single drone is yet limited by its physical features. To better enhance the capability of drones, we have devised and implemented a fleet based multi-UAV platform. Our proposed platform consists of powerful network functions and enhanced control...
The consequence of level measurement cannot be overstated. Inaccurate or inappropriate measurements can cause levels in vessels to be excessively higher or lower than their measured values. Ultrasonic level measurement is one of the best technique used for continuous level measurement. In this project we are using HC-SR04 to measure the level in the water tank and AVR Microcontroller to control it...
SwachhBharat Abhiyan (English: Clean India Mission and abbreviated as SBA or SBM for “Swachh Bharat Mission”) is a national campaign by the Government of India, covers 4,023 well populous cities and towns, to keep the areas and infrastructure of the country clean. The aim of this mission is to clean and cover all the rural and urban areas of the country so that to present this country as an ideal...
IoT devices are becoming increasingly intelligent and context-aware. Sound is an attractive sensory modality because it is information-rich but not as computationally demanding as alternatives such as vision. New applications of ultra-low power (ULP), ‘always-on’ intelligent acoustic sensing includes agricultural monitoring to detect pests or precipitation, infrastructure health tracking to recognize...
This paper deals with the idea of upgrading the current car parking assistants based on ultrasonic sensors to enable them to assist with backing-up with trailer attached to the car. Basic ideas, models and algorithms are presented in this paper. Although commercial solution of the trailer backing-up assistant is already on the market, this approach is unique in extending the use of ultrasonic sensors...
Roller element bearings are a common component and crucial to most rotating machinery; their failure makes up around half of the total machine failures, each with the potential to cause extreme damage, injury and downtime. Fault detection through condition monitoring is of significant importance. This paper demonstrates bearing fault detection using widely accessible consumer audio tools. Audio measurements...
Currently, traffic congestions are the most serious issues that most cites are facing. In order to improving the urban traffic orders, as well as to alleviating traffic pressures, this paper presents an urban traffic control system, which is designed based on the real time traffic flow information. The proposed design has combined with traffic control theory, application of single chip computer and...
Evolution of technology has always been endeavored with making daily life simple. With a fast paced life everybody today is harnessing the benefits of technology except some parts of the society. One of them is the visually impaired who have to rely on others for travelling and other activities. This paper aims at providing one such theoretical model which incorporates the latest technologies to provide...
In recent times, migrating from touch-based input systems to gesture recognition based touchless input systems has become one of the major research problems, considering the health hazards exposed in public usages of the devices. The problem still remains mostly unsolved as such a system having the properties of being low-cost, ultra-low-power and easy-to-use is yet to be proposed in the literature...
Wireless acuusuc sensor networks (wasns) are a promising technology for performing acoustic surveillance because of their flexibility and low cost. However, their commercialization is nowadays limited due to their high energy consumption, which is mainly a result of the high data rates required to stream audio data between sensor nodes. In order to improve energy efficiency in WASNs, we explore the...
