修正駕駛汽車習慣之省油案
修正汽車駕駛喜歡猛踩加油踏板之習慣,把一加油動作分解成多段階級式加油動作,使自動變速箱內扭力降低達到順利變換高速檔o 達到節約能源.減少污染.提高效率之目的。The oil-saving project by adjusting the driving habits To avoid the habit of easily step the pedal to speed up, we divide it into multi-step fuel-filling procedures. Therefore, they decrease the wristing strength of transistor inside auto speed-changing box and reach high-speed brake smoothly. As a result, it can save energy, reduce pollution and increase high efficiency.
Automatically Categorizing Commercial Segments Using Multiple Computer Vision Techniques
The purpose of Computer Vision is to understand the methods by which humans\r process visual information and likewise to create computer algorithms similar to these\r processes. Through careful observation, a computer algorithm was developed to mimic\r how humans recognize logos in television commercials. After visual analysis of\r numerous commercial sequences, it was hypothesized that the key frames (frames in\r which the logo resides) could be found using the intersection of color histograms; the\r logo region could be found using the edge density within the key frames; and the logo\r could be identified utilizing a correlation method with a database of stored logos, scaled\r to different levels using Bilinear Interpolation.\r Color histograms were implemented using one-dimensional arrays with 24 bins;\r key frames were determined by calculating the intersection between consecutive frames’\r color histograms. The edge density was calculated by convolving the key frame with\r the number of edge pixels within a 21X21 area. The identification of the logo was\r determined by computing the Sum of Square Differences between the logo region and\r the database of logos on different scales; SSD values were normalized for different\r scales.\r The algorithm was tested on 14 different sequences and determined the key frame\r with 80% accuracy. By segmenting the sequence into two key frames, the algorithm\r generated 93% accuracy. The algorithm also identified the logo region with 93%\r accuracy. The identification of the logo yielded anomalous results. These data suggest\r that motion between consecutive frames in commercial segments decreases around the\r display of the logo. They also suggest that the logo region has the most visible edges\r within the key frame.\r Future study includes a complete overhaul of the logo recognition algorithm. The\r correlation algorithm (SSD) does not work accurately enough to be used. Therefore, the\r next step is possibly to look at the edge information about the key frames. As the Canny\r algorithm determines the edges of an image, it has to determine the direction (or\r orientation) of the edges. Therefore, a proposed study includes utilizing an edge\r orientation histogram of the database of the logos and the key frames. This would mean\r that the algorithm would identify the logo in the key frames by matching edge\r orientation histograms.
安培植物假說
在「植物的秘密生命」這本書中提到植物在電場或磁場中會生長的更好,我最近正好學到了電磁場如何產生,以及一些產生電磁場的方法,所以想利用螺形管線圈來產生均勻的電磁場並用安培右手定則來控制磁場產生的方向來了解電磁場在高低室溫下對綠豆生長的影響. 在本實驗中我利用鐵碗纏繞線圈的方式並通入不同的電流大小來改變磁場的強度,所進行研究所得到的結果顯示（1）綠豆只有在適當的電流大小下所產生的電磁場才可以幫助加速綠豆的生長(2)栽培綠豆的環境所架設的電磁場越高,越能持續讓綠豆的生長加速（3）綠豆的加速生長並不需要整天都通電（4）綠豆在N極朝上的磁場中生長的速率較S極朝上的磁場中要快(5)在較低的室溫下,電磁場加速綠豆生長的效應較能顯現 It has been mentioned that the plants will grow faster in the electronic or magnetic field in the book of “the secret life of plants”, I learned about the knowledge and methods of how to produce the electromagnetic field just now, I use the screw wire to produce electromagnetic field and control the direction by the Amplifier’s rule to investigate the growing speed of green beans under electromagnetic field in those different temperature. In this experiment, I use the wire to screwed around the ironed bowl, and make different electric current to generate different strength of electromagnetic field, the results indicate that (1) The faster growing speed will only exist in some strength of electromagnetic field (2) The higher ironed bowls that full of screwed wire will result in the faster growing speed (3) It will not need electromagnetic field all days (4) The green beans will grow fast in those north magnetic pole than those in south magnetic pole (5)The effect of electromagnetic field to increase growing speed will be significant in higher room temperature
