蝸牛殼的秘密-特奧多魯斯螺旋的應用

世界上最美的比例-黃金比例為1.6180988…,像是希臘雅典的古廟、美術、雕塑、音樂……等等,生活上有許多實際的例子都應用了黃金比例,鸚鵡螺的殼形也是自然界黃金比例的實例之一。經由日常中實際觀察,發現每個蝸牛殼形大多都是螺旋狀-與鸚鵡螺形狀大致相符。然而日常生活中常見的蝸牛殼形是否就存在著黃金比例呢?經過運用畢氏定理、尺規作圖以及特奧多魯斯螺旋描繪出蝸牛殼的形狀、再用電腦製圖做更精細的確認之後,說明了蝸牛殼形中藏著黃金比例,證明「自然就是美」。

通天神「碳」─探討碳類對色素的吸附能力

本組結合暗箱及光度計組成自製光度實驗儀器,並利用廢棄電腦風扇及強力磁鐵製成自製攪拌器,探討影響活性碳吸附能力的因素,本組測量紫藥水透光度,求得透光度與其成份龍膽紫濃度的函數關係;並利用過量的NaOH(aq)與銅離子發生沉澱,算出一克活性碳可吸附龍膽紫及銅離子的個數。結果顯示增加紫藥水濃度或減少活性碳質量,甚至升溫,活性碳吸附龍膽紫效果均增加。但溫度對其吸附能力影響較小,若將紫藥水溫度從30℃加熱至90℃,活性碳吸附龍膽紫的個數只增加百分之十,攪拌時間則並無規律影響;而一克活性碳可吸附的龍膽紫與銅離子個數比約2:1。本組也取了竹炭及木炭,比較其吸附色素的能力,結果活性碳吸附能力最佳,竹炭及木炭無明顯吸附能力。

黑龍仔知人間冷暖

為了瞭解黃斑黑蟋蟀叫聲和溫度之間的關係,我應用物理熱平衡原理,自製水浴槽控制環境溫度,以電腦錄音程式分別錄製15℃、20℃、25℃、30℃、35℃時的蟋蟀叫聲,利用Sound Forge軟體分析並比較不同溫度下的各種特性。結果發現所分析的chirp、chirp period、syllable period、pause均和溫度呈負相關,而單位時間內的叫聲次數則與溫度成正相關,並推導出15~35℃範圍內蟋蟀叫聲次數與溫度成正相關的公式。最佳直線為:﹙15秒內叫聲次數+19.385﹚÷2.483=當時溫度﹙℃﹚,呈高度正相關﹙相關係數:0.9398﹚。本實驗也比較母蟋蟀對不同溫度下雄蟋蟀叫聲的偏好程度,發現母蟋蟀較偏愛25℃時的雄蟋蟀叫聲,此結果可能與雄蟋蟀在25℃時叫聲的波形最為穩定有關。為探測蟋蟀觸角上的溫度感受器位置,我們曾將不同部位的觸角加以剪除,結果顯示觸角剪除面積越大的雄蟋蟀越不傾向鳴叫,但無法證實是否為溫度偵測異常所導致。本實驗除供學術研究外,因黃斑黑蟋蟀在世界各地均有分布,所以希望能藉由分析溫度與蟋蟀叫聲的相關性實驗,未來嘗試能探討其在不同環境的適應行為亦或種化的可能性。另外,全球暖化問題日益嚴重,也希望能藉由相關實驗探討暖化對蟋蟀生態上的影響。最後,我們的實驗證明了蟋蟀叫聲和環境溫度確實有極大的關聯性,未來或許能參考蟋蟀感覺溫度的機制,製作出一個天然零污染的溫度計。 To find out the relationship of cricket’s calling and temperature, we use a hand-made water-bath tank to control the temperature and record the callings with microphone and software, Sound Forge. After analyzing the collected data, we’ve found that cricket’s chirp, chirp period, syllable period, and pause are indeed affected by temperature (15 degrees - 35 degrees C). Moreover, we also compare female cricket’s preference to the callings, and the result indicates that female cricket’s preference is changing with temperature. In the last, we tried to find out where the thermoreceptors are by cutting out the antennae. After cutting, crickets tend to not to make any calls at all, so we conclude the antennae might play an important role in sensing and calling. The experiment proves that this communication system is temperature coupled. Because the cricket, Gryllus bimaculatus, is a worldwide species, we may learn the accommodation or the possibility of performing a new species by researching the relationship of temperature and cricket’s callings. By the way, the Green House Effect is getting more and more serious, so we want to search for the influences on crickets that are caused by Green House Effect. The last but not the least, according to the report, maybe we can investigate the mechanism of sensing temperature and then make a natural thermometer that is no pollution in the future.

應用生物特徵及視覺密碼學防治車輛失竊和酒醉駕車

車輛遭竊以及酒醉駕車對社會安全造成的危害普遍存在於世界各先進國家。以目前看來,此問題並非嚴刑峻罰就能解決的。若本研究計畫將來普及應用於大眾,必定可以同時減少車輛遭竊之機會和預先防範酒醉者開車駕駛。 生物特徵泛指指紋、虹膜、臉型、聲紋甚至DNA 等等,它的特性即每個人均具有此獨一無二的性徵,加以應用就如同無法被仿造或偷竊的身分證明。若車主能利用自己的生物特徵為車輛上鎖,即可防止車輛遭竊。 視覺密碼學是屬於資訊隱藏技術的一種,藉由兩張以上的影像疊合後呈現其中隱藏之機密資料。雖然視覺密碼學原先純粹是為了加密資料,但我們將之加以修改,設計出複雜且無意義的偽裝影像,使其不易被酒醉後神智不清的人疊合成功而讀出其中的加密資料。 結合生物特徵及視覺密碼學,即可設計出一套可安裝於車上的系統,不僅防止車輛失竊又能防止酒醉駕車事故的發生。 ;The damage which is caused to social security by car stealing and drunk driving universally exist in others developed countries. As things are, these problems can not be solved by severe law. If our project can be applied in the masses extensively, it must be able to prevent both car stealing and drunk driving. Roughly speaking, biological characteristics mean fingerprint, iris, face, pronunciation and DNA. Their uniqueness is a special feature that everyone has. If we can apply it more, the characteristics are identification that can not be imitated or stolen. If the car owner can use his or her biological characteristics to lock the car, the car stealing could be prevented. Visual cryptography belongs to a kind of information hiding. By stacking two or more images, user can recognize the secret information hiding in the stacking. Although visual cryptography is merely created for encryption at first, we modify it and design a complex as well as meaningless stego-image. That makes the unconscious driver who is drunk fail to both stack the images and recognize the secret information hiding inside. We combine biological characteristics with visual cryptography and design a suit of system that is able to install in the car. This system can prevent not only car stealing but also drunk driving.

奈米微粒現形記~化學反應速率的探索

In order to facilitate a paradigm shift from traditional high volume chemical experiments to an environmentally friendly microdose experiment; I had to innovate and overcome a lot of difficulties. After six generations of experiment design I successfully reduced the volume of the combined reactants to a single drop. I utilized many recycled components to build my apparatus including a vintage computer, a simple CD disk, optical sensors and a transistor from a common computer mouse. By using a CCD monitor with an external camera feed, the single drop chemical reaction can be observed in real time and a recording of the event can be made. I chose the focus of the experiment to be the reaction of sodium thiosulfate and hydrochloric acid to create a colloidal solution of sulfonium nanoparticles. By employing a custom-made transparency target to achieve a higher precision of measurement I have also conducted deeper research into the reaction order and the rate constants. 為了將傳統高劑量的化學實驗順利的推向顯微液滴的化學實驗上,今年我們更是創新突破了很多困難的關卡。 儀器設計由第一代減量研究到第六代的減量設計,目前已能成功的運用報廢的光碟片、報廢的電腦、報廢滑鼠內的感光二極體元件及電晶體來自製設計出兩反應物各一滴溶液做自動偵測反應的記錄。透過顯微鏡加裝的CCD電子螢幕目視觀看、拍成電子影片檔由電腦播放的目標。 因此,我選定了硫代硫酸鈉溶液和鹽酸溶液反應可產生硫奈米微粒的膠態溶液作為實驗的主軸及設計可較精確定量的投影片載液面,我們也企圖對其反應速率式的級數及反應速率常數做更深入的探討。

灰階影像內容之檢索技術

資訊時代的來臨,促使我們的社會型態大幅改變,無一不朝數位化的方向邁進。網際網路與資訊科技的快速發展,近年來影像資料庫和數位圖書館大量的成立,關於影像資料檢索的研究已漸漸成為一門極為重要的研究議題。在本研究報告中,我們提出一種植基於向量量化編碼法的灰階影像檢索技術。向量量化編碼法是一種極為簡單的影像壓縮技術。我們應用這個編碼法,來萃取出灰階影像內容的特徵值。同時我們也計算出整張影像與影像中間位置的像素平均值,作為日後檢索影像時過濾掉影像資料庫中不需要比對特徵值的依據。\r 我們所提出的方法能有效地萃取影像內容的特徵值並且讓使用者可以快速且正確地查詢到所需要的影像。當影像資料庫中存在與查詢影像完全相同的影像時,我們的檢索技術都能在第一時間第一順位檢索出這張影像。即便影像資料庫中不存在與查詢影像完全相同的影像時,我們的檢索技術平均74.3%也能在第一時間前五個順位檢索出最相似的影像。\r \r With the coming of the information age, our sociological system change extensively, and everything has moves toward digitization. Due to the rapid development of Internet, information technology, the rapid growth of image databases and digital libraries recently, the related researches of image retrieval have become a very important issue. In this memoir, we propose an image retrieval scheme based on the vector quantization to retrieve similar images from the image database according to the pre-collected image features. Vector quantization is a very simple image compression scheme. We have applied vector quantization to extract features from grayscale image. In order to speed up the retrieval process, we also calculated the mean pixel values of whole images and the central part of the image to filter the images, which are significantly dissimilar to the query image.\r The experimental results show that our proposed approaches can effectively extract features from the image and enable users to retrieve images from image database quickly and accurately. When images stored in image database match query image, the proposed scheme can instantly retrieve the stored image at the first rank. Even though images stored in image database query image exactly, the proposed scheme can instantly retrieve the stored image over 74.3% at the first five ranks.

The discovery of America

1.- Purpose of the research This Game is a new education system, where we take as reference a historical event called "The Discovery of America." The objective is to implement a new way of teaching materials using the technology developed in recent decades, where the teacher uses a modern and educational support to keep the mind of the student in ongoing activity; this will allow greater retention which gives result better understanding and more knowledge. The system is designed to model how to teach with the versatility of being a teacher to provide knowledge through a book because it contains the text outlined and summarized the history and examination by the implementation of questions that offer 4 possible answers and answering incorrectly restart the game, it forces the player to pay attention and remember information. 2. Procedures It divided the two-step strategy: 1. Define the game. The player is asked to bring the features of the game. It must recognize three: a) The technical aspects, allowing the appropriation of technological language and sometimes the understanding of the technology used to play is essential for future acquisitions; b) the commercial tab: identify which company developed the game, age or classification suggested, price, where purchased, country of origin, etc.., a review of the business tab allows to point out habits, and c) a description of the game, review of the plot, characters, history, objectives, modality, gender (role, simulation, strategy, battle, etc..) duration, etc.. This category allows the recognition of recreational preferences of the subject. 2. Thinking the game. Before, during or after the game the subject must think what you do to win or how the game unfolds. Contrary to what seems, while playing one thinks and sometimes thinks that performing other tasks and this time it is the player or the viewer understand the way it works and identify the physical or mental is used to play, trying to understand what I do but most of all how I do it, it is metacognition. 3. Data This prototype is structured in RSS: stands for Ruby Scripting System: System with Ruby Scripting for games. Object-Oriented programming "OOP" is a model used by the most programming languages, that lets you use objects and their relationships to program what will be the final application. In order to expand its use were included languages spoken in America and expanded platform for different operating systems. 4. Conclusions With this fun game is a simple way to learn the story in time, the environment and the circumstances where the player is the student of our system that shapes the teacher, book review, making it a modern and practical way to teach with the advantage of keeping the mind active during the use of our game, this allows the continued interest in the student normally lost in conventional classes.
