This paper addressed the retrieval of land surface temperature (LST) from combined mid-infrared and thermal infrared data of the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Suomi National Polar-Orbiting Partnership (S-NPP). To efficiently remove the effect of the direct solar radiance, a relationship between direct solar radiance and water vapor content, view zenith angle and solar...
This paper proposes a new approach for constrained multiple model (MM) maximum a posteriori (MAP) estimation through the expectation-maximization (EM) method by using our previously developed constrained sequential list Viterbi algorithm (CSLVA). The approach is general and applicable for any type of constraints provided they are verifiable. Specific algorithms for implementation are designed, and...
Remote sensing is an important technology in the field of drought monitoring. Most traditional methods by remote sensing construct relationship between image features and land real data. Usually the models are complicated and the parameters are difficult to confirm. The surface water directly influence the irrigation and drinking, so monitoring water area changing can reflect drought situation. In...
If ubiquitous learning is to be effectively developed and feasibly applied to education, it is necessary to evaluate its effectiveness. Using fuzzy theory, the ubiquitous learning evaluation model is established in the paper. Evaluation index system is formulated which accords with ubiquitous learning and learners characteristics. Put forward subjective and objective weighting method to determine...
Trajectory planning is essential in many applications, such as search and track missions by unmanned aerial vehicles (UAV). In a dynamic situation, events that call for a plan change may occur. Such events include the arrival of a new command or intelligence, detection of a new target, loss of a UAV, a sudden change of weather, etc. Therefore, a plan update is necessary and an appropriate time horizon...
Privacy is a very important issue when storing electronic medical records. According to the definition set out in the Health Insurance Portability and Accountability Act (HIPPA), the confidential section of the electronic medical record needs to be protected. Thus, a mechanism to protect the patient's privacy is needed during electronic medical record exchange and sharing. The privacy protection mechanism...
This paper introduces that the representation and storage of hierarchical model via a database table, achieves the dynamic generation and management of model. It main achieves model base based on AHP. That addresses a number of unstructured or semi-structured problems such as assessment and prediction in the modeling. Focusing on the creation of their corresponding AHP-based method base is to solve...
Active Queue Management (AQM), which can maintain smaller queuing delay and higher throughput by purposefully dropping packets at intermediate nodes, has been intensively studied. Most of the existing AQM schemes focus on the stability, but neglect the fairness. The unfairness caused by the multiple congested gateways and heterogeneous Round Trip Time (RTT) is common in all AQM schemes. In previous...
This paper firstly presents the concept, the competitiveness of construction projects, from the competition's perspective and the difference between construction projects competitiveness and competitiveness of the construction units. Secondly, the article describes the how the competitiveness of construction projects come out and analyzes the relationship between the competitiveness of construction...
The selection of the distribution network connection mode is the precondition and key base work for improving the technical and economic of the distribution system. To take into account the influence of uncertainties in power network expansion planning, the fuzzy and blind number theory is deduced and used for measurement and calculation of uncertain information which influence the final decision...
