Entropy based determination of optimal principal components of Airborne Prism Experiment (APEX) imaging spectrometer data for improved land cover classification
High resolution data hyper spectral land cover classification feature extraction
2014/12/15
Hyperspectral data finds applications in the domain of remote sensing. However, with the increase in amounts of information and advantages associated, come the "curse" of dimensionality and additional...
We provide a short proof that a 5-connected nonplanar apex graph contains a subdivided K5 or a K−4 (= K4 with a single edge removed) as a subgraph. Together with a recent result of Ma and Yu tha...
The Kelmans-Seymour conjecture states that the 5-connected nonplanar graphs contain a subdivided K5 .
Effect of Local Heating around the Tomato Shoot Apex and Flower Clusters on Plant Surface Temperature and Characteristics Related to Fruit Yield
energy-saving fruit set percentage pollen fertility surface temperature thermography
2010/11/24
Heating costs have become a problem for greenhouse tomato production because of the rapid increase in fossil fuel prices in recent years. To reduce fuel consumption without decreasing crop yields, it ...

2009/9/3
Natural circulation experiments were conducted at Oregon State University using the advanced plant experiment (APEX-CE) integral system test facility as configured to simulate a typical 2×4 Combustion...
不同温度对APEX园艺专用控释肥料养分释放特性的影响研究
温度 AP EX控释肥料 养分释放特性
2009/5/22
试验研究不同温度对APEX园艺专用控释肥料养分释放特性的影响结果表明，3种控释肥料释放速度均
受温度的影响，且随温度的升高而释放速度加快，释放周期相应缩短，但3者对温度的敏感性不同，常绿植物肥尤其是P、K易受温度的影响，木本植物肥释放速度受影响最小，其养分释放也很平稳，控释效果最佳。
The Effect of Irrigating Solutions on the Accuracy of the Raypex5 Apex Locator
Electronic apex locator irrigation root canal therapy
2009/4/2
Background: It is of great importance for clinicians to have confidence in the accuracy of an electronic apex locator in the presence of an irrigant. The purpose of this study was to evaluate the ef...
Changes in cortical negative potential associated with local anesthetization of apex of tooth root
Cerebral negative potential Chewing motion Electromyogram Local anesthetization Periodontal membrane
2008/4/19
To determine whether cortical negative potential (hereafter referred to as CNP), which was recorded from the scalp (sites: T3, CZ and T4), preceding the right-side chewing is affected by input from th...
