本研究是由一個棋盤遊戲推廣延伸而來的,研究內容為紅棋先走或後走,若紅棋壓在藍棋上面,則紅棋獲勝;若藍棋壓在紅棋上面,則藍棋獲勝。(也就是說紅、藍棋在同一方格時,遊戲就分出勝負了。)而本研究分成兩種遊戲:遊戲1:紅、藍棋只能上下左右移動、遊戲2:紅、藍棋除了可上下左右移動外,增加可向斜的移動方式;若紅棋每一次走 步、藍棋每一次走 步,且雙方的起點分別在任意位置的方格中,分別去推導雙方剛好走完或少走k步就分出勝負的最短步數、最短路徑數、雙方分出勝負時的所有位置個數、所有位置(坐標)以及分出勝負的判斷準則,最後由上述遊戲1及遊戲2推導出來的公式,透過演算法並利用程式軟體-R語言寫成程式碼作驗證。

本研究主要是探討影響磷光物質放光情形的因素,如:磷光物質本身的條件,周遭環境的狀態,以及照射光源的波段分佈與強弱。 首先,我們先透過光譜儀對照射光源進行分析,並觀察在不同條件的光源照射下,對磷光樣本發光情形的影響;接著,再利用加熱器調整樣本周遭的環境溫度,探討在不同的溫度環境下,對磷光樣本發光情形的影響;最後,改變磷光樣本的照光表面積與厚度,觀察這些條件對磷光樣本發光情形的影響。 透過本研究的結果,讓我們更瞭解影響磷光反應的因素,藉此希望能讓我們有朝一日可以實現我們的夢想─教室留影牆的設計。

Autonomous Vehicle
This is the self-driving and navigating vehicle which follows a track. This robot is made by our group. We made this robot together assembling the parts. This robot is commonly used in industries to shift goods and product. In this robot we have arranged all the things also metal detector which buzz when a metal is detected under it. This robot helps a lot in industrial life and is also easy to make if we learn the steps. This robot also needs programming to make it work. The programming software used for it is known as Arduino IDE. This is the figure of this robot in industries. Here the people are keeping goods in the pickup and shifting them. This robot can also run in white track, only if we do the programming right for the white track. Nowadays in cars too this type of system is used like example: Tesla model X. In the car this system is used and to avoid the obstacles something named Lidar is used. To make this vehicle follow its track and the motor to run different things are used like IR Sensor, and L298N motor driver module respectively.

本研究透過ROS(機器人運作系統)實作一個結合自由探勘、SLAM(同步定位及地圖構建)及物體辨識之機器人系統。利用ROS機體與程式軟體分離的優點,本研究開發出的系統並不僅侷限於在一種機體上使用,對於任何能安裝ROS或與ROS連結之機體都能使用,供各式各樣的服務做為一系統性的路徑規劃器及運動基座。除了導航功能外,機器人透過攝影機得以判斷自己現在身處的環境而並非單純繪製地圖,且能讓人更容易地對機器人下達指令;更因其特化的避障機制,本研究的系統很適合在日常辦公室工作環境中做為助手。以實際環境及模擬器探討此系統擅長及較不適用的環境,呈現目前機器人系統的運作能力。

本研究自製排水模型與設計連通管的水位觀察法,來探討水槽排水速度的影響因素,結果發現排水速度的影響主因有三: 1.水漩渦:當水槽內的水排出時,水流穩定沒有旋轉、或者破壞水流旋轉使其不產生漩渦,會加速排水的速度 。 2.空氣:當水漩渦產生時會造成水槽上方的空氣往下流動,如果阻擋空氣的流動就可降低水漩渦的產生,提升排水的速度。 3.排水孔洞:排水孔洞越大,排水效果越好,但同時也更容易因為水的初始旋轉而產生水漩渦,降低排水的速度。 最後,利用水流阻擋板與空氣阻擋板來破壞水流旋轉,使其無法產生水漩渦,造成水管充滿水而產生虹吸現象,進而加速排水的速度。

An Analysis and Optimization of Double Parallelogram Lifting Mechanism
Double Parallelogram Lifting Mechanism (DPLM) is a compact and stable lifting mechanism with a large extension range widely adopted in robot designs. Rubber bands and springs are often installed on the DPLM to lighten the motors' load and maintain its height, yet the installation positions are often obtained through trial and error. This project aims at finding the optimal rubber band installation positions for DPLM using modeling and optimization techniques. A mathematical model which describes the forces and moments acting on all the linkages of DPLM was derived based on the conditions for the static equilibrium and verified with a 3D simulation software. A genetic algorithm (GA) was implemented to optimize rubber band installation positions, which managed to find solutions with the overall root-mean-square- error (RMSE) of the net moment less than 2 for 2 to 6 rubber bands. A further statistical analysis of 50000 random rubber band samples showed that installing rubber bands in triangles is the best solution with the overall lowest RMSE. A test was conducted with a prototype of the DPLM and the results were consistent with our model and optimization. This project derived and verified a mathematical model for the DPLM, and found the optimal way and positions to install rubber bands. The results of this project provides a theoretical basis for controlling DPLM with rubber bands, allowing it to be further adopted in industrial robots that require repetitive lifting and lowering such as inspection robots and aerial work platforms.

本實驗研究-小麥、花生殼、龍眼殼、咖啡渣、葵瓜子殼是否有隔熱和隔音的效果。 以白膠和糯米為黏著劑製成各種殼板,測量其在不同厚度時,在室外陽光和室內燈光下的隔熱效果,以及不同波型和頻率下的隔音效果。實驗顯示: 一、五種殼板都有隔熱降溫的效果,效果最好可達到15℃(白膠底)和13.2℃(糯米底) ,平均花生殼版的隔熱效果最好。 二、氣溫越高,殼板的隔熱效果越好。 三、殼板的密度對隔熱效果影響不大,但對隔音有一些影響。 四、隔板增厚之後,隔熱不一定變好,但咖啡渣、小麥隔熱效果可增加4℃之多。 五、殼板都有隔音效果,0.5公分隔音效果最好的是咖啡渣,1公分效果最好的是龍眼殼。 六、殼板增厚後隔音效果都變好,只有咖啡變差。

實用顛倒蛋之最佳製程研發及創新機台製作
去年地區科展已經成功找出顛倒蛋的製作方式,其缺點是煮蛋的環節需要一個人一直不停的翻轉蛋,從今年的結論可看出已改進了,其中: 結論一:顛倒蛋製作步驟中的「煮蛋」 的部分自動化(機器在P。12) 結論二:找出快煮爐煮顛倒蛋的模式(煮蛋時間及溫度表在P。24) 結論三:快煮爐煮顛倒蛋工具已著手申請專利 在顛倒蛋原理探討的部分,使用Photoshop將圖片二值化,得到蛋黃佔51。28%的數據(P。15),和去年地區科展報告推論的50%非常接近;更製作了流速檢測儀(P 。16),發現蛋白和蛋黃流速的不同,猜想流速不同是製作出顛倒蛋的重要原因。

探討水體表面張力對蚊蛹和四齡幼蟲存活率與羽化率之相關性
蚊蟲的幼蟲期與蛹期均生活於水中,需浮至水面藉由呼吸管呼吸,因此如何維持呼吸孔的順暢換氣成為幼蟲和蚊蛹的生存關鍵。本研究藉由添加界面活性劑至水體,改變水體表面張力,使蚊蛹和四齡幼蟲呼吸構造因無法正常發揮效果而達到減蚊或滅蚊目的。 本篇論文分成三個部分研究:在無氧氣供應下,發現蚊蛹存活的時間較四齡幼蟲短。接著,比較不同表面張力下,蚊蛹和四齡幼蟲的存活率與羽化率的大小。結果發現能夠讓蚊蛹和四齡幼蟲存活的水體,表面張力須大於34 (N/m)。最後,模擬蚊蛹和四齡幼蟲的呼吸管,設計口徑大小不同的模型,探討水體表面張力與進水程度相關性。由模擬結果得知,口徑越大以及表面張力數值越小時,模型越容易進水。

Using P.I.P. to strengthen roads: Plastic incinerated by plastic
People have become accustomed to single-use plastics. These are plastics that are used once only and are then thrown away or recycled. A piece of plastic can only be recycled 2-3 times before it is of bad quality and can no longer be of use. (Achyut K. Panda, 2019). Plastic waste fills up landfills and oceans, becoming hazardous and harmful to wildlife, while emitting greenhouse gasses. Alternatives, such as metal straws and paper bags have turned out inefficient and plastic is still a great need in society. Another way of getting rid of waste plastic is to burn it. Fossil fuels such as coal and natural gas are being utilised to burn plastic in industry. This causes many harmful emissions, such as carbon dioxide and carbon monoxide released from burning the plastic. It results in more damage being done than just leaving the plastic in a landfill. These emissions can be cleaned before being released into the atmosphere. Plastic is made of petroleum, so when it is burned it is converted back into a fuel. Plastic can be burned under controlled conditions to create a fuel source that can be used, thereby utilising the waste plastic. The research conducted aims to investigate the use of plastic waste to burn other plastic to create a renewable fuel source and to eliminate plastic waste.

Safety First:分析商場內部貨架擺設
在實體店鋪進行限時搶購活動 (Flash Sale),近年來已逐步在世界各地快速散播。在這樣的閃購活動期間,商場往往會宣傳銷售商品的巨幅折扣,吸引消費者。消費者在閃購的活動期間,爭先恐後的進入商場,過程中,除了可能造成消費者的傷害外,亦有可能造成商品本身的損傷。 本研究發想自第六屆數學建模挑戰賽之國際賽題。首先,本研究分析了商品損壞的各種方式。第二,本研究用虛擬的商品列表,與一個虛擬的商場平面配置圖作為規劃範例。第三,繪製並配對完貨架與商品後,運用賽題中的專家評分、剩餘數量等數據,寫出了每個商品的平均歡迎指數。第四,建立數學函式,計算路徑風險值,並藉由定量分析預測,成功地判斷哪一個以及哪一些商品的受歡迎程度會較高。最後,提出了優化於賽題給予的平面配置圖方式。
