Educational peer assessment has proven to be a powerful approach for providing students timely feedback and allowing them to help and learn from each other. In an educational setting, most peer assessment consists of a single round. The problem with this setting is that, either the authors do not have a chance to update their work, which makes the suggestions from their peers useless, or the author...
Remote sensing techniques applied in crop monitoring and management can help to reduce the input of nitrogen without reducing crop yield and accurately predict nitrogen demand [1]. The objective of this study is to use the ground based multispectral images to predict canopy nitrogen level for soybeans in southwestern Ontario. A light weight multispectral camera were used to collect multispectral measurements...
Positron emission tomography (PET) plays an important role in neurodegenerative disorder diagnosis and neurooncology applications, especially detecting the early metabolism anomalies in human brains. Current lesion detection algorithms can be roughly classified into voxelbased, region of interest (ROI)-based, and global algorithms. These methods may capture the scale and/or location of the lesions...
Consideration on the unmanned surface vehicle (USV) rapidity, maneuverability and anti overturning resistance, this paper creates a synthetical optimization mathematical model of the new USV navigation performance, structure of a complex algorithm, preparation of the related software. Complete a number of optimization calculations, discuss the effects of weight and different speed on the optimization...

Parallel to algebraic methods, graphical circuit analysis methods have the advantage of cancellation-free. This paper proposes a graph reduction method for hierarchical symbolic circuit analysis by applying a binary decision diagram (BDD) for data sharing. This method is extended from the Graph-Pair Decision Diagram (GPDD) method which was developed for two-port dependent sources. New graph construction...
The paper established a mathematical model of integrated optimization of the navigation performance for a high-speed ship, improved the genetic algorithm to a new parallel genetic algorithm based on the sensitive variable, and applied to an integrated optimization problem of high-speed ship navigation performance. Compared with GA, the optimization results indicate that the improved parallel genetic...
Fourier transform is presented and applied to monthly composited NDVI data to over one year derived from MODIS to examine the frequency distribution of the multi-temporal signal. It is shown that frequencies of the time series of NDVI are linked to integrated NDVI and seasonal variabilities of different periods of the land cover types. The 1/12 month-1 frequency component summarizes the relative dominance...
