隨著全球石油能源短缺，世界各國無不積極尋求永續開發且無公害污染之能源方案，而利用海洋能量發電的形式已成為世界諸國積極研究之重要課題。本研究利用近海岸浮體式波浪發電設計，並利用波浪理論推導與波浪實境測試之方式，創作出在波浪中之發電系統。發電過程為波浪推動浮體，浮體拉動水下的掛重移動，透過掛重上的橡膠管經由摩擦力效應拉動波浪發電機模型的旋轉輪，此刻旋轉輪的轉動與波浪的波高、週期產生連動效應，進而轉換擷取波浪能量，並利用此波浪發電方式，設計研發出『危險水域波浪警示燈』模型，且能在海中真實運作良好成功。

Paralysis is a debilitating disorder that does not currently have safe and effective treatments. Implantable brain electrodes can be used to read brain waves and convert them into a corresponding motor function to restore movement in paralyzed patients. Tissue deformation induced around the implant site is believed to reduce their viability through the foreign body response. Developing electrodes that minimize deformation is challenging because the mechanical aspects of deformation are not fully understood and non-animal tissue models for testing electrodes are unavailable. Development of pre-clinical models for in vitro testing of the mechanical properties of electrodes can lead to a better understanding of this prevalent problem. The objective of this study was to construct a novel contrast-enhanced, brain mimicking hydrogel using photopolymerizable polyethylene glycol (PEG) polymer that contains alginate microspheres with enclosed gadolinium (Gd) contrast agent. 1.5% alginate microspheres were constructed with enclosed Gd-DTPA-BSA contrast agent and successively added into 10% PEG. Then, this mixture was photopolymerized using a 5 mW/cm2UV lamp to result in a successful brain mimicking hydrogel. Rheological testing showed that its elastic modulus was approximately 1.5 kPa, which is similar to that of a normal human brain. The model is valuable because the presence of the contrast agent in the hydrogel resulted in distinct bright spots on the MRI. This can facilitate the visualization of tissue deformation caused by electrode insertion via comparison of pre-insertion and post-insertion images. This brain-mimicking model has the potential to improve understanding of neural deformation from electrode implants in order to assist patients suffering from paralysis.

The aim of the work is inventing the way in which the power of the ICE is the same and consuming of the fuel decreases. The following methods of investigation were used: analysis of the experience of the improvement of ICE, modeling, the brainstorming, methods of Decition Theory of Invention’s Tasks (DTIT). In this work Ivan Semyonov based on a hypothesis that if the non-supporting combustion exhausts will be drawn with the vacuum from cylinder fuel for the same power it needed less. The practical meaning of this work is in the attempt of studying the question of improving the ICE for getting and making the more perfect ICE.

In the future, energy supply is the most serious problem to our society due to the shortage of fossil fuel. We should try to save energy as much as we can in different aspects in order to maintain the sustainable development of our society. According to the statistic report of electrical end uses 2008, showing that Space conditioning and Lighting shared 27% and 12% of the total electricity supply respectively. We design this “Free-Dome” to provide the individual users unique spaces for their work or entertainment where the lighting and temperature are easily and freely controllable. As a result, we may save lots of energy by reducing the lighting and space conditioning to the unnecessary area or public area.

用塑膠軟管作為氫爆安全反應器，從封閉端點燃氫氧預混氣，管中火焰\r 傳遞快速，肉眼難以觀察，因此研製「氣爆顯影記錄器」來觀測，如下圖，\r 光纖導引偵測點的火光至暗箱，記錄於高速旋轉的軟片，從光電轉速計讀取\r 轉速，軟片沖洗後量測各顯影間距，可得火焰位置與時間的關係圖，量測時\r 間最小刻度可達2. 2 微秒。\r 解讀軟片的顯影，得知氫爆初期，火焰加速傳遞，大部分在25cm 位置\r 左右，火焰的速率出現急速飆升(爆燃轉變為爆震)，而且火光亮度也急速升\r 高，有時火焰速率出現飆升過高，再回降趨於穩定?的現象，在50 cm 位置\r 左右，火焰進入等速傳遞階段，此階段有穩定的火焰模型，火焰頂端的亮度\r 最高，往後亮度遞減。

The applications of digital image are rapidly growing with the developments in computer technology. This enforces digital image industry to produce devices with better quality. Despite the today’s advanced level of technology, it is known that input and output devices somewhat cause color distortions. International Color Consortium suggests that we can use ICC profile to overcome the problem mentioned above. But the related hardwares and softwares are too expensive for the general users. In this study, we base on the ICC profile’s mechanism to develop a color calibration method for low cost image acquisitions. From the theoretical and experimental results, it can be demonstrated that our method appears satisfactory.數位影像的應用隨著電腦資訊科技的快速成長而蓬勃發展，這也促使著數位影像工業的相關產品漸漸地普及與廣泛地使用，時至今日，雖然有著很好的製造技術，但是任何數位影像設備均無法完美無失真地將原有的色彩呈現出來或紀錄下來，或多或少都有色彩偏差的存在，尤其在價格越低廉的設備上更為明顯。雖然可以依據國際色彩協會的建議，使用每項設備的專屬色彩描述檔來克服色差的缺點，但是用來產生色彩描述檔的相關軟硬體均價格昂貴，實非一般使用者所能承受的負擔，本篇研究以色彩描述檔的色彩轉換機制為基礎，發展出針對廉價取像設備的色彩校正程序，無論從理論數據上的探討以及實際影像上的測試看來，我們的校正方法確實有效，讓原有的色彩能精準地重現。

由現有立體相機與人眼之差異發想，本研究架設模擬可調參數之雙相機系統，拍攝兩眼影像，並在偏光式立體顯示系統平台中，定義立體影像品質，如:合成難易、凸出程度、變形程度，並讓受測者評估，以俾找出立體影像品質影響因素。研究發現:透過視線三角形模型推算拍攝立體影像時，最佳鏡頭間距約為6公分，並得以預測與控制立體影像凸出螢幕之距離。我們得到最佳鏡頭間距與影像顯示距離，也發現可旋式鏡頭對變形的影響，並藉由人因工程的研究方法，利用受測實驗得到的結果與參數，建立了一個具有可旋式鏡頭的立體相機雛型，期許未來可將可旋式鏡頭之設計積體化，進而製成一具有最佳立體影像品質的實體相機。

The time is changeable between 1-99 seconds. Also there are four square lights fitted with the main counter to illuminate the colors. Auto Traffic detector. There are three sets of switches in front of each traffic light to detect if the road is clear for the cars to enter the next road. Red light crosser detector. After the signal become red this system will operate to detect any car try to cross the red light by the car cutting the switch two times.

高分子發光二極體乃是利用電子和電洞在發光工作層結合而形成激子，激子在形成後隨即以光的形式衰退，而發出光來。一般而言，高分子發光二極體是一種三明治的形式，電子注入層/發光工作層(高分子)/電動注入層，而通常我們會選擇加入電子傳遞層和電動傳遞層，來增加其發光效果。本研究係針對聚苯胺做為電洞傳遞層對發光二極體之影響，分別對有電洞傳遞曾和無電洞傳遞層之發光二極體作導電度測量、循環伏安法、電位-電流測量、亮度-電位測量。發光二極體中所須之高分子層，須利用旋轉塗佈機，將其均勻的披覆在載體上，由於本校並無此儀器，所以將離心機改造成簡易旋轉塗佈機，並觀察其披附之效果。另外，在封裝元件時，係因學校缺乏真空蒸鍍的儀器，所以將利用電鍍法把鋅鍍在ITO玻璃上，或將鋁片和ITO玻璃緊靠在一起，針對此二替代方法，本研究將探討其所製出原件成效。Polymer light emitting diode (PLED) utilizes the energy gap between the layer of electron and electric hole that emits the light due to the decay of solitron. PLED is always in the sandwich from, that means the conducting polymer is contained between metal as an cathode and indium tin oxide as an anode. It is used the addition of another electric transfer layer and electric hole transfer layer to improve the lighting efficiency of PLED. The purposes of this study are to discuss the effect of polyaniline as the electric hole transfer layer. The study methods are conductivity measure, the cyclic voltametry, the luminance-voltage curve. The simplified spin coating machine was designed to coat the polymer onto the ITO. The zinc was electroplated onto the graphite as an cathode.
