在數個火星探測任務都有觀測到火星火山口和深坑的沖積物的景觀，可推測為有流體(風與液體)沖積而成，因此可做為有水的間接證據之一。但全球性的沙塵暴只能告訴我們此時的火星是缺乏液態物體固定這些沙塵，因此造成全球性的沙塵暴，是無法提供有水的證據。 火星快車號（Mars Express）和火星偵察軌道器(Mars Reconnaissance Orbiter, MRO)的雷達資料顯示兩極和中緯度地表下存在大量的水冰。2008年7月31日，鳳凰號(Phoenix)的挖掘實驗，任務人員由影像判斷表土之下證實有水冰的存在。

從有關黑洞數字的兩個有趣問題開始引起我們的研究興趣，進而自創互補數差法則，繪製出自然數大爆炸圖譜，發現可以用因數分析法預測和檢驗圖譜中的數圈系的類型及大小。我們也從數圈系觀察到數圈內的數字存在著等倍數列的關係，於是創造出 K--N 法則，繪製出 K--N 大爆炸圖譜，並在繪製過程中發現橡皮筋現象。最後我們分析 1--N~4--N 大爆炸圖譜，得到許多從來沒有人發現自然數黑洞現象的奇異結果。

Sicherman Dice 就是一對點數配置與正常骰子(6 面正立方體，點數為1到6) 不同的骰子，它所拋擲出的每一種不同點數和(2,3,4...,12) 的機率恰好與一對正常的骰子相同。這種骰子是美國的Col. George Sicherman 所發現的。 Sicherman 更進一步指出：在不使用Sicherman Dice的情形下，不可能找到一組大於或等於三顆的非正常骰子，它們拋擲出的每一種不同點數和的機率恰好與一組同數量的正常骰子相同。本研究的目標在於1. 尋求計算「Sicherman Dice的組合和正常的骰子有相同的出現機率」的方法2. 證明Sicherman 結論的真偽及是否適用於其他正多面體(4 面/ 8 面/12 面/ 20面) 的標準骰子3. Sicherman Dice (Crazy Dice)的延伸探討(1) 不同面數骰子的組合，是否可以找到面數組合相同，但點數配置不同的 Crazy Dice( 如4 面與6 面的標準骰子組合，找到4 面與6 面的Crazy Dice)(2) 多個面數相同或不同骰子的組合，是否可以找到面數、個數及點數配置皆不同的Crazy Dice ( 如3 個4 面標準骰子組合，找到2 個8 面的Crazy Dice)同時我們也和Col. George Sicherman取得聯繫，討論當年他發現Sicherman Dice的經過及其結論的限制條件，作為本研究未來發展的參考。

如果你養過這種體色鮮紅的螯蝦，相信對於牠強大的破壞力及奇持的習性感到好奇，事實上這種外來種的螯蝦即可使水壩崩潰及破壞稻田生長，此外這些螯蝦居住的環境，更只有少數動物及螯蝦能生存。關於這些習性和行為及各種構造將以觀察和實驗的方式來求知，了解這群強而有力的外來螯蝦之特性。

作者從事國中物理教學多年，學生對熱學所發生之疑難甚多，但國中物理課本及一般補充教材等對熱學方面的實驗探討並不多，作者希望藉此研究、新設計一些這方面的實驗裝置，或作者過去曾設計的熱學實驗裝置，再研究改進，使其更精良，更能提高學生學習熱學的興趣，或能將一種實驗裝置，達到多用途實驗的目的，以增進教學上的效果。

在民俗體育競賽期間，常常看見同學練習扯鈴，踢毽子和跳繩。其中跳繩一項大家認為最有趣，尤其是花式跳繩（五六位同學成一組，其中兩人各拿繩子的一邊旋轉，中間成二個圓圈，再由二人或三人拿短繩進去跳）同學們都拍手叫好，我卻對中間的二個圓圈圈發生興趣；奇怪呀？為什麼可以成為兩個圓圈圈呢？所以我和幾位同學一起在老師指導下研究這個問題。

自從高三接觸到地球科學後，深覺鄉上環境與居民生活息息相關，休戚與共的，所以環境品質之優劣，為值得重視的課題。近年來，高雄市快速成長，雖成為全省首屈一指的工業都市，卻使市場居住的生活環境受到文明副產物之嚴重污染，其中以水污染產生的害處，對市民生活構成很大威脅。根據最近之報章雜誌報導中，顯示高雄地區河川，以後勁溪水質污染負荷量最為嚴重，身為高雄市民的一分子，對自己生長的鄉土，應付予積極關懷，囚此我們乃利用寒假課餘時間，對後勁溪水質污染情形，作實地調查研究，期能喚起大眾正視水污染問題，共同維護純潔水質，為創造更潔淨，美好的明天而努力！

半年多前，我在一本有關機率的書上看到如下的題目：某女與男友相約，在下午五時至六時之間，在公園門口見面，先到的人應等候二十分鐘，求此二人在門口相遇的機率。當時我就想：如果相約的人有三個、四個或更多的話，這個機率要如何求呢？於是就著手開始研究，得到結果之後，只覺得高興，並沒有想到居然有機會把它寫出來。

本篇採用薑做為材料，主要探討薑抗氧化能力與環境因子的關係，結果發現老薑的抗氧化能力優於嫩薑、環境因素對薑抗氧化能力的影響力依序為光(紫外線)＞溫度＞酸鹼＞金屬離子(鎳、鋅）、薑黃萃取液也具有阻絕紫外線照射及能抑制微生物生長（薑黃含量20%時抑菌率為49%）。此外，實驗過程改良前人氫氧自由基測試方法，配合自製光度計，得到標準曲線R2為0.9078，也免去須貴重儀器測量之不便。

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.

Transiency… something which only stays for a short time, and changes\r frequently. You’re probably wondering now what this has to do with our sports and\r we must admit that at first sight it really doesn’t seem to, but think of the world an\r how many changes sports have experienced. Is it not time we thought of how sports\r facilities could be improved? And what if you were told that there would be an\r “ever-changing” sports centre which you could use?\r You really might get the chance to use such a sports centre one day, and that’s\r what our idea is all about. A multipurpose sports center is what you could call it, but\r it’s not in the least like any one you’ve seen before. In places like Hong Kong, where\r space is everything, multipurpose sports centers are common, but they always have\r so many colored clines that tend to confuse both players on the court and spectators\r off the court. Just how often have you seen referees and players arguing about\r whether the ball is out or not? And how often have you found that you are not\r enjoying the game as much as you should? Yup, we’re sure it happens all the time,\r but you don’t have to worry anymore, as our innovative design will solve all your\r problems. Yes, its time for us to change…\r In our dream sports mat, we’ll have lines which can change and also detectors to\r tell you where the balls land. You’re probably thinking, “Lines which change?”, and\r yes that’s it! The perfect solution to all those confusing lines would be lines which\r could change their positions. And to do this, we’ve made use of some new technology\r called ‘E-INK’ which would make this possible. Of course it sounds like something\r which is really costly but in fact, this technology doesn’t cost that much and its really\r durable, so it’s really worth the money to start changing. Moreover, these mats can\r also be rolled up and stored somewhere else, so when you don’t need to use the sports\r ground you can just pack it up and the venue can be used for other purposes.
