Cloud contamination is the most common defect leading to quality degradation in remote sensing images. Numerous cloud-cover assessment (CCA) methods have been developed in the literature. The traditional Landsat 7 CCA algorithm attempted to detect clouds by taking advantages of different spectral properties from five spectral bands. However, it suffers the weakness of omitting thin cirrus clouds and...
The learning problem of ranking arises in many tasks, including the question answering, information retrieval, and movie recommendation. In these tasks, the ordering of the answers, documents or movies returned is a critical aspect of the system. Recently, deep learning approaches have gained a lot of attention from the research community and industry for their ability to automatically learn optimal...
Learning a deep architecture involves a tough issue called hyperparameter search. This is especially the case for convolutional neural networks with a large number of hyperparameters. To solve this problem, we propose a tensor completion method to predict the best architecture configurations for convolutional neural networks. This method is based on a hypothesis that the generalization performance...
A model considering water vapor condensation process is built in this paper to simulate the process of airship ascending more accurately. In order to consider the difference of skin temperature around the airship surface, the skin of airship is divided into small grids. The radiation heat absorbed by the internal gas when the skin is semitransparent is calculated with an improved net heat method....
Unmanned Aerial Vehicles (UAVs) are widely used in military and civilian fields, which promotes the need of networking. Due to the complex features of UAV MANET, the development of UAV MANET faces many technical challenges, such as routing. Generally speaking, Optimized Link State Routing (OLSR) protocol gives better performance on delay compare to AODV protocol, so the OLSR protocol meets the high...
While providing protection for users' privacy, anonymity network has also been exploited by criminals to carry out crime anonymously. We study the problem how to break the unlinkability between the senders and recipients in order to identify the source of anonymous traffic in this paper. Tor, the most widely deployed anonymity network, is selected as our target. We develop a de-anonymize attack method...
The automobile warranty period is developing towards long-term warranty direction (160000 km or 10 years), and about 50% of car registrations within 10 years are eliminated. Due to this, information on discarded cars for reasons like obsolescence or outdated need to be considered while estimating the lifetime characteristic in the reliability assessment. Owing to setting of the long-term warranty...
Because of the fast and convenient accessing to network, commodity management and selling with network has been widely applied to various kinds of industries. Accordingly to jewelry, which is different from other commodities, a jewelry management and sell system based on .NET MVC framework was designed and built on the visual studio 2010 development platform with SQL server 2008 express database in...
Global path planning of in a static environment is an important problem for a mobile robot. Biogeography-based optimization (BBO) is a population-based evolutionary algorithm that is based on the mathematics of biogeography. It mainly uses the biogeography-based migration operator to share the information among solutions. Differential Evolution (DE) is a fast and robust evolutionary algorithm for...
Microfabracation is the critical technology to obtain microelectromechanical systems (MEMS) parts. Nowadays, microfabrication technologies are usually based on the mask lithography and Focused-ion-beam (FIB) sputtering, which are in fact two and a half dimensional (2.5-D) fabrication and are difficult to fabricate real 3-D parts. Based on the real 3-D fabrication technology of two-photon of femtosecond...
