On Course Line Management

The Online Course Management system was developed in 2012 by George Moon to address the issue of creating course books at Burnside High School in Christchurch, New Zealand. The course books are designed to inform students, staff and parents of the many courses that are available for students to choose for their next year of study. In the past, the system that the school used consisted of large amounts of paperwork and duplication. Not only did this system require a lot of effort from staff, but the course book cost the school thousands of dollars to produce, as it had to be sent off to be published into a large book that would be read by students for a week, then likely thrown out. This year the school decided to digitise the course book, so that students would look at their courses online. Earlier this year, the school believed that the new School Management System (SMS) ‘KAMAR’ would be able to handle all of the necessary information, however this was not the case. Because of this, they needed a simple solution that would collate all of the course data, and then output it as a course book. I developed my project to do this. It is a web based program that is accessible by staff on their computers which enables them to enter in all of the course and assessment data for their departments. As it is all securely stored on a central database, it reduces duplication and staff workload, as well as the added environmental bonus of less paper being used. The program also outputs data in a number of ways including as a coursebook PDF (digital document which can be uploaded or printed), an Excel spreadsheet and a webpage for easy viewing. It can be sorted or printed by different categories (such as level, faculty, department), which proved to be a very useful feature. Following some research on areas such as design principles, browser compatibility and screen resolution (computer screen size), the program was designed to make best use of this this information. For example, most of the computers that staff would access the website on were of a similar size screen, so I made sure that my website worked well for them. I also used my research on design principles to try and create a simple, clean interface that users with limited computer skills would easily be able to navigate around. The outcome was real, as it was used by the school to generate their coursebook this year. Following a 95% student completion rate of course selection many months earlier than previous years, the system (although it had some issues) was pronounced a success, and the school is looking to use it in the years to come. There are a number of steps I am looking to take in the future with this program including the potential sale to other schools, so they can take advantage of the features it has to offer.

當「皇后」遇見「小三」-正三角形棋盤上的皇后互不侵犯問題

如下圖所示,在一邊有6個圓圈的正三角形棋盤,將某個圓圈擺上皇后,此為皇后的根據地,箭號所指的三個與邊平行的方向,是皇后所能管轄的範圍,且兩個皇后不能互相管轄到對方的根據地,不是根據地的圓圈可以兩個皇后共管。我們的研究在討論一邊有n個圓圈的正三角形棋盤中使每個圓圈都被管轄到時,最少需要幾個皇后以及最多可放幾個皇后。為了解最少需要的皇后數,我們採用算術推理以及從三個方向(↘、↙、←)的考慮、由外而內的一整排來作邏輯上的推理得到了一邊有1~12個圓圈的正三角形棋盤的最少皇后數,並嘗試透過電腦程式的執行求出更大邊圓圈數棋盤的最少皇后數。最多皇后數部分,我們透過數學歸納法得到了所有邊數情況的最多皇后數。

智慧型搬運機器人

在這充滿創新的時代,智慧型機械的發展顯的非常樂觀,也發展得非常快速。用電子結合機械可說是最佳搭檔,可以預料以後智慧型機械會越來越聰明,到那時家裡也不用請傭人,買個機器人就行了,工廠裡再也看不到搬運工及插零件的女工,都將被高效率的機器人帶替。 我們也熱愛於這方面的研究,經過多次製作,發展了第二部機械人,第一部無機械手臂,第二部增加了一支兩個自由度及自動尋找目標物的手臂,使得它更具有智慧。 在製作機械人上,最困難的就是感知器的製造,而我們依據最簡單的物理現象製造出交通號誌識別感知器,障礙物感知器等。當然這些感知器如何和它的頭腦——電腦連結也是一門學問,需要不斷地實驗改造,改造實驗,現在製造出來的智慧型機械人,雖然還沒有發揮到最理想,但是它是我們花費相當多的時間所造成出來的結晶。相信以後我們會再造出更理想的機械人。

終端速度

液體中之球體運動與液體的黏滯性有關,本實驗找出球體半徑與終端速度之間的關係。利用攝錄機作為紀錄工具,拍攝三種材質(壓克力、玻璃、水晶)的球體在沙拉油中的自由落體過程。使用電腦影像處理軟體將影像分解成幅影像,時間的解析度為1/30秒。測量球體的高度與時間,分析高度與時間的變化情形,發現終端速度與球體半徑之間的關係。 流體中之運動方程Fdrag = -k1V,無法符合實驗結果。我們的實驗結果顯示油中的自由落體的運動方程應該是Fdrag = -(k1V+ k2V2)。由不同材質的壓克力球(~1.18g/cm3)、玻璃珠(~2.47g/cm3)與水晶球(~2.66g/cm3)所獲得的終端速度(Vt)與球體半徑(a)的關係為a3(ρ-ρ') = 0.00003(a Vt)2 + 0.00021(a Vt) + 0.00575,其中ρ與ρ'分別為球體密度與沙拉油密度(0.90 g/cm3)。 再者,在相同半徑的條件下,密度越大的球體終端速度越大,在靜止下落後,越久達到終端速度。 The motion of a sphere which is falling through a fluid is subject to the fluid viscosity. In this study, we find out the relation between the radius of a sphere and the terminal velocity. We used a digital camera to record the sphere's descent in the oil. The three kinds of sphere we choose are acrylic(~1.18g/cm3), glass (~2.47g/cm3)and crystal (~2.66g/cm3). Frame-by-frame analysis of the video footage yielded rough estimates of the sphere's location within 1/30 seconds accuracy for statistically consistent results. By measuring the location and time and analyzing them, we find out the relation between the radius of a sphere and the terminal velocity. The expression of the drag force,Fdrag = -k1V, is not cosistent with our results. The study indicates the expression of the drag force should be Fdrag = -(k1V+ k2V2). The expression for the terminal velocities of the three kinds of sphere is of the form:a3(ρ-ρ') = 0.00003(a Vt)2 + 0.00021(a Vt)+ 0.00575, where a is the radius, ρ is the sphere density and ρ' is the oil density(0.90 g/cm3). In addition, if the radius is the same, the terminal velocity of a denser sphere is higher and the time to approches the terminal velocity is longer.

智慧型日光燈節能系統

本研究以增進日光燈管使用效率為目標,設計出一套整合型的系統以減少不必要的浪費。我們將感知用的硬體設備與自行開發的軟體程式作結合,使系統能夠在感知到日光燈管的各種狀態後,做出相對應的處置。其狀況包含:1.無電時系統會警告,以避免誤判的情形;2.有電時燈管正常運作;3.有電時燈管閃爍或不亮,此時系統會切斷日光燈管的電力,並記錄資訊。以上述系統為基礎,我們搭配紅外線模組來達到有人在才開燈,無人時自動斷電;亦加入偵測環境用的光敏電阻來達到光線暗時才開燈,光線亮時會自動斷電。依據測試,閃爍的燈管會比正常燈管多消耗30%的耗電量,壞掉不亮的燈管亦會消耗正常燈管70%的耗電量,對能源越來越少的今天,我們的系統提供了另一種節能的機制。

四面體體積平分面的包絡方程探討

剛開始考慮平分物件時,我們從二維的多邊形部分著手,後來發現已經有人做過相關研究,並且得到類似的結論。這個部份顯現出面積平分線與其包絡曲線間的密切關係。我們將其中的方法和結果加以歸納、改善,為了更全面地研究,我們推導出一般性的包絡方程。之後當我們推廣到三維領域時,發現四面體體積平分面與之前的結論有些相似之處,平分的情況卻也更複雜,我們將推導的結果用電腦軟體呈現出來,以便更深入地了解它。最後嘗試了相當抽象的高維積平分,結果仍具有工整的對稱性,讓我們充分領略了數學之美!When considering bisecting a subject, at first we focused our attention on 2-D case, polygons. But afterwards, we found there were already some similar studies conducted by other students, which indicated the close relation between the area-bisecting lines of a polygon and their envelope. We rearranged their methods and results, and then made further improvement. Moreover, in order to study the bisecting problem entirely, we derived the general envelope equation. Then when extending the generalization to the 3-D case, we came to the conclusion that tetrahedrons’ volume-bisecting planes is similar to that in 2-D, but the circumstances are more complex. We tried to show our result with the aid of software, hoping to understand it fully. Finally, we tried to do the case in higher dimension, which is very abstract, and the result was clear-cut symmetrical. During the studying process, we had seen “the beauty of mathematics.”

AI人工智慧與樂高積木之結合與應用

Tic tac toe (井字棋)是大家童年時期常玩的小遊戲,本研究希望能以人工智慧的概念編寫出能在遊戲中立於不敗之地的程式,並將程式寫入LEGO EV3主機,利用LEGO積木打造出一台能與人對下井字棋的機器人。在研究的過程中先將井字棋遊戲可能出現的棋路一一列出,再從中找出中最適合的應對棋路,並在遊戲過程中利用顏色辨識零件去偵測對手下棋的位置。經過測試,它的確能夠在遊戲過程中立於不敗之地。未來希望能針對更加複雜的賽局,例如象棋、五子棋或4*4、5*5的方格等,設計出能從人手中輕易取勝的機器人。

中華民國第三十一屆中小學科學展覽-應用科學科評語

本組共有六十一件作品參加評審,計選出前三名作品十四件、佳作十三件,茲將本組評審結果敘述如下: 國小組作品一般水撙,較往年略為遜色,可能是受到參展安全規則的限制,題材的選擇,較不容易。作品總類,以環境汙染及保護較多,研究層次偏重於現象的觀察,較難發揮基本的科學研究精神。得獎作品突出之處則為題材明確,成果及步驟完整。 國中組參展作品質與量均表現平平,作品水準,差異亦大,可能因受聯考的影響,參加科展意願不高。首名得獎作品,因研究步驟,符合科學精神,並提出解決問題的方法,得以脫穎而出。 高中組作品具多元化,部分作品,仍侷限於市售產品的裝備,科學研究的態度及方法,稍嫌不足,高職學生作品,較往年進步。 國、高中二組,雖然國際科展選拔在先,但作品水撙,較去年提昇。電腦科技應用、學理探討、實驗數據整理與應用、文獻探討等方面,均有長足的進步。
