During the launching vehicles design and their optimization process, the implementing of aerodynamic characteristics (AC) database is quite important. Accuracy of such database determines quality of the pre-flight simulation, trajectory and even the whole design direction. However, the database building process is one of the most challenging...

Model predictive control (MPC) is an advanced control technique that offers an elegant framework to solve a wide range of control problems (regulation, tracking, supervision, etc) and handle constraints on the plant. The control objectives and constraints are usually formulated as an optimization problem that the MPC controller has to solve ...

: Tooth extraction is one of the most common procedures in oral surgery. However, it is complicated as well as not fully understood. Different teeth have different structures and strengths. Even teeth of the same type differ depending on ages, genders, races, and other reasons affecting its integrity. During the procedure, the properties of the...

Power system blackouts have been observed increasingly frequent and severe. As an emergency control action to rescue the system from complete blackout, under-frequency load shedding (UFLS) technique can disconnect a part of the load when a disturbance occurs and an excessively low frequency is detected. Traditional UFLS scheme is widely adopted...

The major goal of this master thesis is to improve truck safety and comfort during lane change manoeuvres. This thesis focuses on the scenario of the driver doing sports exercises inside the cabin when the vehicle is driving automatically on a highway. This topic is one of the foci of the international GlobalDrive project from Technical...

Motion simulators have increasingly been applied for research purposes due to their large motion capabilities and short response time. Key applications are including vehicle simulation, experiments on control behavior in virtual environments and studies into human self-motion perception. To maintain a good dynamic capability, the known motion...

Indoor localization is a topic of significant interest for academic and in dustrial. For outdoors, we have Global Positioning System (GPS) working very well, but GPS does not work indoors and we spend more than 90% of the time indoors. Thus, there is a great need to find solution for this prob lem. Many technologies have been proposed for indoor...

Sandwich composite is commonly used as a material of wind turbine blades. In order to meet the practical needs, the design of sandwich always contains some designed-in imperfections, like ply drop of facing laminates, core with resin grid and so on. These unavoidable designed-in imperfections may induce delamination problems and result in huge...

Gated communities are recognized as a global phenomenon. During a long period of urban development, gated community becomes the most widespread Chinese residential type. It is usually surrounded by fast motor vehicle lanes, therefore lack of social connection with surrounding areas. And due to the few connection, the streets out of gated...

Augmented Reality equipment is currently growing and showing a lot of promise. However, the equipment suffers from a few aspects: lag, range of vision and price. In this report an Augmented Reality system will be made by connecting two cameras through an FPGA to the VR system to cover all aspects that Augmented Reality suffers from. While the...

Based on the recently developed mimetic spectral element method, we propose an effective numerical scheme for solving three-dimensional periodic incompressible Euler flows, which spatially preserves mass, kinetic energy and helicity. Preserving multiple integral invariants numerically will significantly contribute to the stability and accuracy...

From the Medieval Walled City model to the contemporary Grid City model, the anthropocene CITY has evolved as a new species to a stage that surpasses humanity. Its main goal is efficiency and prosperity of the city itself instead of individual human aspirations. At this moment the city has repressed individual by collective goals, it is no...

For energy management in wireless sensor networks, only the sensors with most informative measurements are activated to operate. How to select sensors that make good tradeoff between performance and energy consumption is what many researchers are focusing on. Existing solutions assume analog data model, i.e., the data from sensors collected by a...
