Ambient assisted living (AAL) technologies can help the elderly maintain their independence while keeping them safer. Sensors monitor their activities to detect situations in which they might need help. Most research in this area has targeted indoor environments, but outdoor activities are just as important; many risky situations might occur outdoors. SafeNeighborhood (SN) is an AAL system that combines...
Aimed at the disadvantages of traditional monitoring system, an underground pipeline security early warning system based on wireless sensor network was designed. The system employed a dynamic cluster head election of the clustered network structure, taking CC2530 as the core of wireless sensor nodes. The sensor nodes stored and analyzed the data, using a new type of optical fiber temperature sensor...
In this paper, we describe smart sensors, actors, user, alarm system, smart appliances of our proposed smart home model. We also describe the main problems of the smart home which are safety, security and energy saving. In our smart home model wireless sensor, actors, smart appliances, and user communicate with each other and with the central system. Sensors collect data about abnormal home situations...
This paper presents a smart cage which consists of an automated excrement detection module, a cleaning module, a feeding module, and multiple additional sensors for a dog. In the smart cage, excrement is detected by using image processing methods and is automatically cleaned up by the conveyance. Moreover, the conveyance can also be a treadmill for the dog to exercise, with its built-in and adjustable...
A sinkhole is occurring in urban area all over the world frequently, in fact, it is a roadside subsidence in geological terminology, which can harm property and safety of government and many people. To detect the roadside subsidence earlier, we monitor the aged or damaged underground infrastructures, report the sensed the values to analyzing system, and draw out the risk index of the roadside subsidence...
The helicopter speed reducer contains pinion gear, shaft, bearing, flange and other types of accessories. Due to the complexity of mechanical structure, the health characteristics have too much associated factors. In fact, the health monitoring on speed reducer have difficulties on its validity and practicability. Based on the analysis of existing problems of current research, this paper studies failure...
In this paper we have provided public Smart Assistance in Public Transport System. The project is to be implemented for public bus (for ex: PMTs in Pune). It has the entire smart assistance system required for public security and safety. The smart system includes safety for women as well. It has accident detection and monitoring facility. It also has user friendly application for user to track bus...
Complexity and electrification of automobiles increases steadily, which involves an enhancement of safety-requirements of applied E/E-components, controllers and their connection and interaction in between. As a fundamental safety-relevant standard, the E-Gas monitoring concept has been introduced in the '90s. Recently, a new version of this E-Gas monitoring concept has been published, which includes...
With the implementation of the national internet plus strategy, more and more devices enjoy the chances of getting access to internet. But for devices like sensors whose resources are quite limited, it is a tremendous challenge to link to the Internet by using the traditional communication methods. Taking the memory size, computing power and energy consumption of the resource-constrained device into...
This paper describes the concept of the portable system for monitoring thermal exposure of firemen and other rescues. The system measures, archives and analyses actual external and internal temperatures affecting the monitored person and gives him a warning in case of dangerously increased values. Described is the construction and electrical components of the device, some important tests done in various...
In this paper a new approach for safety monitoring of dangerous gases in the industrial plants is proposed. A single artificial neural network is used for determination of the gas concentrations based on sensor array measurements, performing at the same time compensation of the temperature and humidity influence on the sensor outputs. The obtained results show good accuracy in gas concentration estimation,...
This paper reviews the current sensor technologies and communication methods available for mine safety monitoring. Wireless Sensor Network (WSN) technology use in recently developed mine safety monitoring systems is highlighted and compared with traditional wired monitoring systems.
Presently industrial automation is growing rapidly emphasizing on centralized monitoring and independent control of sub-systems. This increases the number of remote sub-systems, which need intermediate communication. Another challenges observed are the reduction of system size and the maintenance cost with flexibility in operation. Regulatory, repetitive sequential control and interlocking are the...
Enabling kitchen safety is crucial for elderly people independent living. Cooking, usually, is accompanied with several risks particularly for elderly people, due to aging associated impairments. Therefore, cooking-safe environment is required to enhance safety of elderly people. This is the motivation behind our research work on building a cooking-safe system. In this paper, we present the fuzzy-logic...
The NFR (Non Functional Requirements) framework was used to quantitatively evaluate software architectures. Assurance cases using GSN (Goal Structuring Notation) have not been applied to quantitatively evaluate software architectures. In this paper, GSN will be extended to define quantitative attributes for this purpose. Then, the architecture evaluation method based on the attributed GSN method will...
In this paper, it discusses and performs lab experiment of detecting LQI value from ZigBee wireless sensor network and from the variation of LQI values to determine is there any intrusion. In closed and no one existence indoor area it has a steady LQI value while it changes when someone intrudes into the area. An intrusion detection system is developed by using the variation in LQI values. After the...
Geological environment monitoring in mines is important field of Wireless Sensor Networks (WSN).When environmental conditions changes continuously & abrupt event occurs then that challenges can be accepted by miners. So prediction & prevention technique is used for monitoring. A design of a wireless sensor network will contain communication protocol & a Self-Adaptive WSN system...
Wireless Sensor Networks (WSN) is an emerging technology with a potential to revolutionize the way we sense and transmit the information. The applications are many and look to be limited by our imagination and ingenuity. Some of the important applications are process monitoring, military surveillance, structural health monitoring, environment monitoring, health monitoring, Nuclear, Biological and...
In this article, the authors propose a distributed infrastructure for intelligent building control using multi-agent technology, based on their own solutions. The novelties are regarding to modified Modbus communication protocol that was obtained by reorganization of the protocol data structure while keeping the standard functionality for legacy devices, innovative hardware controllers as communication...
The impending increase in silicon wafer diameter from 300mm (the current industry norm) to 450mm will increase the surface area of each wafer by 2.25 times. A worst-case scenario suggests that flammable process gas flow rates required to maintain wafer throughput at acceptable levels would increase by the same scaling factor driving up to 3 times the abatement requirement. The main reason to go to...
