Dynamic calibration for high accuracy flux control of reluctance actuators

In the semiconductor industry, the demand for a continuously higher throughput puts tough requirements on the force capacity and accuracy of actuators. Reluctance actuators, as a promising alternative to the present state-of-the-art Lorentz actuators, are capable of achieving much higher force densities. On the other hand, reluctance actuators...

Data as a creative material supporting ideation in Ford: creative problem solving with data

Vehicles are becoming more and more connected, and in combination with various services, they generate large amounts of data, which is mainly used in development processes for testing purposes in Ford. However, sensor data has more potentials for product development, and one valuable potential is to contribute to product innovation in the early...

Vessel Layer Separation of X-ray Angiographic Images using Deep Learning Methods

Percutaneous coronary intervention is a minimally-invasive procedure to treat coronary artery disease. In such procedures, X-ray angiography, a real-time imaging technique, is commonly used for image guidance to identify lesion sites and navigate catheters and guide-wires within coronary arteries. Due to the physical nature of X-ray imaging,...

Low power digital baseband architecture for wireless sensor nodes

This thesis presents a digital baseband design for an upcoming wireless standards: IEEE 802.11ah. It is a branch of Wi-Fi (IEEE 802.11) standards. Compared with the previous Wi-Fi standards, this new standard has larger coverage range and consumes less energy. It is particularly suited for energy-constrained sensor applications. In contrast to...

Molecular Dynamics Simulation on Mechanical behavior of Si Nano Cantilever under Ar Bombarding

In nano world, it is cheap and repeatable to make 2-dimensional structures, such as nanoholes and thin nanofilms. However, it is expensive to build 3-dimensional structure in a repeatable manner. Ion bombard- ment is a technique which is widely applied in engineering areas, such as thin film deposition, etching, and analysis. In this thesis work...

LikeChinese-Breaking the Ice in Learning Chinese

The Chinese language is increasingly getting global attention due to the rapid development, especially the huge growth of the consumers markets in China. However, for the majority of western people, the Chinese language, especially the Chinese symbol: characters are something that is interesting but unreachable. From the designer’s experience,...

Critical Success Factors of Applying PPP Financing Model on Urban Subway in China: Harbin Subway Case

For a long time, the development of urban infrastructures has been considered as a national responsibility, which means the urban infrastructures should be invested, constructed and operated by the public sectors. The urban subway infrastructures have the characteristics of large upfront investment, long cycle for return on investment, low...

A Multi-hop Aware Scheduling Mechanism for HSDPA and IEEE 802.11 Integrated Network

By simulating the integrated networks with multiple gateways and TCP flows, we get the unfairness in the HSDPA and IEEE 802.11 integrated networks. The unfairness has two sources: the HSDPA cellular subnetwork and the IEEE 802.11 subnetwork. A novel scheduling algorithm - Multi-hop Aware Scheduling has been proposed to resolve the unfairness...

Gateway Selection Mechanisms for Beyond 3G Multi-hop Cellular Networks

Nowadays, there are a host of demands on the Internet applications (IP based multimedia applications) coming into people’s life. How to access the Internet and get these application services more quickly and better becomes gradually critical for people to meet their demands. However, the existed two technologies: the third generation (3G)...
