Tool Condition Monitoring is very fundamental part of the Manufacturing industry similar to the automation and hence has a great importance in research based on manufacturing engineering. Many of the people those concern with the manufacturing industries are interestedly study the TCM as successful unmanned automation in production is only possible if there is presence of good tool wear monitor and...
Today mobile computing platforms need everincreasing computational performances while their energy consumption is drastically limited by battery lifespan. An optimal operating point is obtained thanks to a compromise between performance and power consumption. For distributed architectures (e.g. MultiProcessor System On Chip), the supply voltage and the operating frequency of each processing element...
Because the import optical pulse width is limited to phonon lifetime T (T = 10 ns for silica fiber), meter spatial resolution can be realized in the Brillouin optical fiber sensor. But centimeter spatial resolution is required in Structural Health Monitoring (SHM). To improve spatial resolution and keeping the import optical pulse width, a technique for fitting the spectrum data of Brillouin optical...
This paper presents the design and development of an online monitoring system that collects data over time or distance with a built-in instrument or sensors. Currently, an online data collection system (Vehicle Data logger) from general vehicle is not available in the market. Only the vehicles' manufacturers have the tool to access the engine ECU to monitor the vehicle's data. Current available automotives...
The ability to predict and prevent equipment failures is essential to various industrial processes and military operations. In recent years, Condition Monitoring (CM) has been recognized as an effective paradigm in this regard. CM can be performed via several sensor channels with broad coverage to enhance monitoring capabilities. However, loss of sensor readings due to malfunction of connectors and/or...
This paper discusses an energy-efficiency supervision and diagnostic system (ESDS) to address the problem that the air-condition system do not perform as well as anticipated. The ESDS consists of a set of sensors, data acquisition system, data analysis and diagnostics system including a web-based remote access system that can be used to identify problems in operations. The operation state of a typical...
This paper addresses the influence of the viscoelastic material properties of adhesives on the functionality of SHM (Structural Health Monitoring) sensor applications. Adhesives behave viscoelastically and show a strong temperature and time dependency of their mechanical properties. Creep processes increase the deformation under mechanical load and relaxation can decrease the stress in the adhesives...
A method for fault diagnoses of hydraulic system for construction machinery and equipment based on the information fusion logic theory is put forward. The theory of the method is described. It can get the data of hydraulic system for construction machinery and equipment by various type sensors. The model of hydraulic system for construction machinery and equipment condition measurement and fault diagnoses...
Research into operational aspects of mini unmanned aerial vehicles (UAV) and structural health monitoring systems (SHM) is being conducted at the Defence Science and Technology Organisation and La Trobe University. A fundamental area of interest is investigating the problems associated with miniaturization of the control and health monitoring sensors for such systems. While many technologies for UAV...
A system for the monitoring of microclimate and air pollutant concentrations in heritage buildings has been developed and validated by means of a measurements campaign in the Villa della Regina, a Savoy residence in Torino. The in situ campaign is currently in progress in cooperation with the Soprintendenza per i Beni Storici, Artistici ed Etnoantropologici del Piemonte. The monitoring system is composed...
Pharmaceutical and healthcare industries are highly regulated industries in each and every nation around the globe. Every nation has a governing body like USFDA, TGA, and M.H.R.A, Schedule-M etc. that assures that the medicines are manufactured under strict guidelines to ensure highest quality of manufactured products. However assuring high quality products requires that the manufacturing facility...
Because of the underdeveloped market for used computers, a large number of functional systems are going to waste. A significant barrier to the development of a market is the inability to communicate the worth of a computer. In order to overcome this barrier, a system for determining the value through monitoring of the conditions under which it is used is suggested. This system uses sensors already...
The capacity to master engines behavior is fundamental for a manufacturer to prove its efficiency in conception and maintenance capability. This understanding goes through the capacity to acquire and treat data flows produced by sensors for monitoring purposes. One of many issues encountered by engine experts when reading measurements is that a given engine never works under exactly the same conditions...
This paper is concerned with the design and development of an on-line condition monitoring system for large power transformers utilizing signals such as transformer vibration, voltages, currents, temperature and state of switches. The system consists of two parts which communicate each other via Ethernet or series port. The formal is a front-end computer subsystem used for data acquisition and processing,...
Maintenance of life safety and engine efficiency coupled with reduced life cycle cost, form the major motivations for the upgradation and development of structural health assessment and management technology (SHAMT). However, there are several major challenges to realizing the full benefits of the technology by many industries, still remain. These include, damage awareness tools and techniques, data...
All sensors or sensor systems previously used for tire measurements have one common feature - the sensors are part of electrically closed circuits and electrical connections are used to form the closed circuits. In this paper, we present a new tire safety monitoring system using a recently developed method for designing, powering and interrogating sensors developed at NASA. In lieu of sensors being...
The ceramic roller kiln with oxygen-enriched and pure oxygen combustion (CRKOC) is proposed by authors. According to the structural feature and thermal characteristics of CRKOC, a new concept is proposed in this paper, which is the kiln body real-time health monitoring of CRKOC. Three aspects are mainly researched. Firstly, the necessity of the health monitoring on kiln is analyzed. Secondly, the...

To satisfy bridge health monitoring and maintain, a novel low cost sensing system for simultaneous measurements of temperature, strain and pressure based on practical fiber Bragg grating (FBG) is reported in this paper. The main principles of multi-parameter are introduced. A wavelength scanning demodulation system based on continuous wave tunable frequency is designed. The practical FBG sensors have...
Environmental monitoring requires that raw data acquired from sensors and/or data repositories be transformed, by scientific analysis, into assessments of current ecosystem conditions and in evolution trends in time and space. The huge data amount produced by different sources, the complexity of the environmental models adopted and the necessary distributed collaboration between scientists and government...
