In air transport, the growing demand in energy along with rising fuel costs is endangering civil aviations optimistic outlook, besides, concerns have focused more on addressing aviations impact on greenhouse gas emissions. Based on the analysis of the necessity of carrying out the work of energy saving, the paper analyzes the factors that have great influences on the energy economy from the multi-criteria...
Remote sensing images are widely used in various fields. However, they are usually degraded by haze. In this paper, a spatial-spectral adaptive haze removal method for remote sensing images is proposed. The proposed method is based on haze imaging model and the dark channel prior. Our method is able to diminish the phenomenon of color distortion and haze removed not completely in different bands....
We study the Imbert–Fedorov (IF) effect in prism coupling configuration with magneto-optical (MO) material, which is called MOIF effect. An effective refractive index method MO waveguide is obtained based on the solution of Maxwell's equations. The expressions for IF and MOIF shifts are also derived. As left-handed circularly polarized (LHCP) and right-handed circularly polarized (RHCP) light beams...
With the rapid development of Internet and cloud services, logs become one of the fastest growing data types in backup storage systems. These massive data always require long-term storage, which incurs high storage overhead. Typical compression algorithms, such as traditional lossless compression and log-specific compression algorithms, are employed to increase storage efficiency. However, these algorithms...
This paper presents an optimal coordinated operation framework for minimizing the overall electricity cost of distributed internet data center (IDC) microgrids, which consists of cost of purchasing power from main grid, the operation cost of onsite generations, and the cost of carbon emissions. With forecasted day-ahead and real-time locational marginal prices (LMPs), the proposed model could help...
Nowadays massive log streams are generated from many Internet and cloud services. Storing log streams consumes a large amount of disk space and incurs high cost. Traditional compression methods can be applied to reduce storage cost, but are inefficient for log analysis, because fetching relevant log entries from compressed data often requires retrieval and decompression of large blocks of data. We...
Visual and near infrared (VIS-NIR) face image matching, which is also called cross-spectral face matching in heterogeneous face recognition, is important for security application. However, most existing methods perform poorly in this scenario because of the cross-modality appearance differences. To address this problem, we propose a new method named multi-feature based Multi-view Smooth Discriminant...
Recent years, data amount is increasing rapidly, indicating that we are in the era of big data, which brings opportunities and challenges. In this paper, we illustrate the big data storage and management status, analyze the problems and finally propose solutions.
We demonstrate a microfiber FP sensor that is manufactured directly in the micro-size fiber by the use of a 193nm-excimer-laser exposure. The spectral characteristics and the wavelength dependency on the external strain, temperature, and refractive index are investigated. The research results are useful for future applications of the devices.
In order to balance the deduplication rate which is an important evaluation metric that determines the disk space saved and the performance influenced by the throughput, and to enhance the capability of the dedupliacation system, a Read Request Sorting and Reorganization Strategy is proposed for avoiding the bottleneck of random read disk detention. The algorithm addresses the data read performance...
In this paper, we demonstrate high-efficiency inscription of Bragg gratings in microfiber. Strong Bragg gratings are easily inscribed using a 193-nm excimer laser and phase mask in microfiber drawn from the 62.5/125- standard multimode fiber (MMF) with no additional photosensitization treatment. The enlarged photosensitive core offered by the MMF provides a sufficient overlap between the...
Freeway and urban road are two relatively independent and interdependent systems. To achieve the smooth connecting of freeways and urban roads is the first premise and guarantee of building a sustainable freeway-urban road system. Connected-way has a node with freeway and urban road respectively, the planning of the connection is how to determine the number of these types of nodes and the specific...
This paper presents a closed-loop design method which has been utilized to evaluate and design the Visual Display Terminal (VDT) system of the hermetic cockpit. Our evaluation steps include: 1) we propose five ergonomic factors of the VDT system, i.e., the Observation Distance (OD), the Illumination Level (IL), the Observation Angle (OA), the Size of the Observation Target (SOT), and the Background...
To utilize efficiently Human Anatomy Network Course, improve students' professional study and ability training. Methods: Establish Human Anatomy network course resource, trying to use it for undergraduate and 7-year students. Investigate the feedback questionnaires about the utilization. The more difference the students' ability, the more difference the requirement of network course. Proper utilization...
In this paper, we propose a joint temporal error control (JTEC) method for H.264 which combines RDO-based macroblock (MB) classification at the encoder and adaptive partition size error concealment at the decoder. The encoder classifies the MBs by evaluating the sensitivity of the MBs as the RD cost between the concealment error and the bits needed for the additional motion information. Additional...
Software development inclined to production of scale, criterion and industrialization, with the development of information technology and software industry. Different kinds of Project Maturity Models for enhancing performances of software development were broadly exploited and used factually. Based on literature review and enterprise research this paper put forward 30 main factors which cover in three...
