Abstract:

Today energy resources are becoming scarcer and therefore more valuable. In conjunction with the population growth over last century, the need for finding new, more efficient, and sustainable methods of agricultural cultivation and food production has become more critical. To facilitate this process, we are designing, building, and evaluating a system for precision agriculture which provides farmers with useful data about the soil, the water supply, and the general condition of their fields in a user friendly, easily accessible manner. Our system aims to make cultivation and irrigation more ef

Abstract:

Analytical force and dynamic models for material removal processes such as end and face milling do not account for material and process related uncertainties such as tool wear, tool breakage and material inhomogeneity. Optimization of material removal processes thus requires not only optimal process planning using analytical models but also on-line monitoring of the process so that adjustments, if needed, can be initiated to maximize the productivity or to avoid damaging expensive parts.

Abstract:

Effective quality improvement in the manufacturing industry is continually pursued. There is an increasing demand for real-time fault detection, and avoidance of destructive post-process testing. Therefore, it is desirable to employ sensors for in-process monitoring, allowing for real-time quality assurance. Chapter 3 describes the application of sensor based monitoring to additive manufacturing, in which sensors are attached to a desktop model fused deposition modeling machine, to collect data during the manufacturing process. A design of experiments plan is conducted to provide insight

Abstract:

The balance of supply and demand of energy is the key factor in the stability of power systems. A small disturbance in the supply demand relationship, if not properly handled, can cascade into a major outage, costing millions of dollars to the stakeholders. Proper monitoring and exchange of critical information in real time is the only solution to prevent the instability in this vulnerable system. But, the disparity in the protocols used by power utilities and the lack of infrastructure for information exchange are proving to be hindrance to obtaining a reliable de-regularized power industry.

Anastomotic leakage (AL) is the leading cause of morbidity and mortality after bowel anastomosis, a surgical procedure used to restore luminal continuity after bowel tumour resection. Even after years of research, its occurrence has not decreased, and new methods of monitoring the wound and predicting anastomotic failure are therefore urgently required. Here we propose the use of an internal coil to increase the signal-to-noise ratio (SNR) during Magnetic Resonance Imaging (MRI ) and/or Spectroscopy (MRS).

This work is an experimental study of applying an impedance-based health monitoring technique to complex structures. The work is presented in three parts. In the first part we consider effects of the following three factors on damage detection abilities: actuator excitation level, test wire length and ambient conditions (temperature, structural loading and vibration). It was concluded that increasing the applied voltage improves the signal to noise ratio and damage detection abilities. Test wire lengths under 30m do not affect damage detection abilities.

The scientific studies associated with material engineering and device miniaturization are the core concepts for future technology innovation. The exploring and tailoring of material properties of amorphous magnetic microwires, recently, have revealed remarkable high sensitive magnetic field sensitivity down to the picoTesla regime at room temperature. This superior magnetometer is highly promising for active sensing and real-time monitoring building block for modern industrial devices and healthcare applications. The low-field, high sensitivity regime of the GMI response over a wide frequency

Abstract:

Online quality assurance is crucial for elevating product quality and boosting process productivity in advanced manufacturing. However, the inherent complexity of advanced manufacturing, including nonlinear process dynamics, multiple process attributes, and low signal/noise ratio, poses severe challenges for both maintaining stable process operations and establishing efficacious online quality assurance schemes. To address these challenges, four different advanced manufacturing processes, namely, fused filament fabrication (FFF), binder jetting, chemical mechanical planarization (CMP), and th

Abstract:

Wearable wireless sensor devices, which are implemented by deploying sensor nodes on objects, are widely utilized in a broad field of applica-tions, especially in the healthcare system for improving the quality of life or monitoring different types of physical data from the observed objects. The aim of this study is to design an in-home, small-size and long-term wearable fall detection system in wireless network by using barometric pressure sensing for elderly or patient who needs healthcare monitoring. This threshold-based fall detection system is to measure the altitude of different position

Abstract:

As the use of Web expands, Web Service is gradually becoming the basic system infrastructure. However, as it matures and a large number of Web Service becomes available, the focus will shift from service development to service management. One key component in management systems is monitoring. The growing complexity of Web Service platforms and their dynamically varying workloads make manually monitoring them a demanding task. Therefore monitoring tools are required to support the management efforts. Our approach, Web Service Monitoring System (WSMS), utilizes Autonomic Computing technology to

Abstract:

碩士<br>國立勤益科技大學<br>電子工程系<br>98<br>Streetlights are necessary for an urban area. However, there is no an effective monitoring system to maintain their functions for normal operating. In Taiwan, power outages occur frequently in the mountain areas whenever a typhoon or earthquake strikes. The lamppost fixed in mountain areas often collapse so that the streetlights are unable to provide emergency lighting. For the purpose of energy saving, emergency lighting and monitoring, we proposes an LED based light monitoring system, which combines an MSP430 microcontroller, solar cells and various sensing e
