With the proliferation of mobile computing and the ability to collect detailed data for the urban environment a number of systems that aim at providing Points of Interest (POIs) and tour recommendations have appeared. The overwhelming majority of these systems aims at providing an optimal recommendation, where optimality refers to objectives of minimizing the distance to be covered or maximizing the...
The exponential growth of high dimensional biological data has led to a rapid increase in demand for automated approaches for knowledge production. Existing methods rely on two general approaches to address this challenge: 1) the Theorydriven approach, which utilizes prior accumulated knowledge, and 2)the Data-driven approach, which solely utilizes the data to deduce scientific knowledge. Both of...
Exploration over large datasets is a key first step in data analysis, as users may be unfamiliar with the underlying database schema and unable to construct precise queries that represent their interests. Such data exploration task usually involves executing numerous ad-hoc queries, which requires a considerable amount of time and human effort. In this paper, we present REQUEST, a novel framework...
A TTL-controlled trigger generator based on pulse transformer and peaking switch is constructed in this paper. The trigger system is composed of two units, which the trigger signal is amplified step-by-step from 5V TTL to 100kV. A dry-type pulse transformer with a winding ratio of 4 is presented. A self-breakdown peaking switch is used to shorten the rise-time of the output pulse. Experiment results...
The proliferation of mobile, ubiquitous and spatial computing has led to a number of services aiming into facilitate the exploration of a city. Platforms such as Foursquare and Yelp curate information about establishments in an area that can then be used for recommendation purposes. Traditionally an approach followed by these systems is to rank places based on their popularity, proximity or any other...
There is mounting evidence that manufacturing energy and environmental costs are a growing factor in the overall energy footprint of computing systems. The quantification of these impacts requires the evaluation of both the manufacturing and use phase energy/environmental costs of major integrated circuit (IC) components, including processing units, memory, and storage. In particular, expansions of...
In the process of sludge treatment, it's a very important technological link of mixing the material, but the key is how to ensure the accuracy and reliability of the feed's weight. The changes in the sludge size, shape, humidity, viscosity, weight, etc. lead to the output signals of the ordinary weighing instrument unstable, so it's difficult to achieve ideal control effect through the traditional...
Fiber-optic photoelectric sensors provide a sensing solution for applications involving small targets or unfavorable conditions. It is, however, recognized that photoelectric signal is subject to temperature drift, and faulty detection could be resulted if proper compensation is not considered during phase of design. In this paper, principle of fiber-optic photoelectric sensors is formulated, and...
In manufacturing industries, two symmetric cylinders of an electro-hydraulic motion system are required to move synchronously for good quality of products and for long lifetime of the machine. In this paper, a robust model-based predictive control (MPC) algorithm is presented for satisfactory performance in terms of tracking and synchronization. First, the synchronization error between different motion...
Flywheel energy storage systems (FESS) with magnetically assisted bearings are becoming an exciting alternative to traditional battery systems. However, one of the challenging problems for such systems is to suppress the gyroscopic rotation of the sensitive rotor subject to internal or external disturbances. This paper presents an optimal control strategy by incorporating cross-coupling technology...
