    傳統聲納系統,目標辨識是由操作手憑藉噪音的節拍、起伏等等節奏,搭配方位、頻譜紀錄圖跡進行判讀。一般來說,在複雜的海洋環境中識別各種目標噪音是件非常困難的事,尤其當目標噪音疑似為魚雷時,操作手需在短時間內做出攸關生存的判斷,心理更是承受極大的壓力。本研究依據艦艏環形聲納架構,提出被動式魚雷輻射噪音辨識技術,研究包括:波束合成、目標偵測、方位追蹤、特徵析出、特徵辨識等五項技術,期望能以電腦輔助操作手進行半人工或是全自動化的魚雷預警任務。結果顯示,運用類神經網路建構之魚雷辨識模型經過945筆數據訓練後,於420筆數據驗測中,其辨識性能對於水面艦目標有高達98%以上的成功率,水下目標則有88%以上的成功率。In a traditional sonar system, the operator identifies targets by listening to the noise tempo and watching the bearing frequency records. Generally, it is often difficult to identify targets in a complex underwater environments. The operator needs to make judgments within a short time, especially as the noise is suspected to be a torpedo. In this research, based on hull-mounted sonar, a technology of passive identification to the torpedo radiation noise is proposed, including beamforming, target detection, bearing tracking, feature extraction, and feature identification. It is expected that with the aided computer, the operator can perform semi-manual or automated tasks dealing with torpedo warning. Finally, a torpedo identification model is built using neural network, for which 945-item training data and 420-item testing data were conducted respectively. The results that show a high identification probability more than 98% for the surface ships, and 88% for the underwater targets were obtained from the model developed.

    在中小型無人飛行載具的動力選擇上,因轉子引擎具有體積小與大馬力等優點,故相當適合做為動力選擇,然而因馬力大且氣封件形狀特殊等特性,對於氣封件材料在耐磨耗與高溫機性的要求相對更高,傳統使用不銹鋼或球墨鑄鐵已經無法滿足引擎性能需求。因此本院為滿足轉子引擎性能需求,以灰口鑄鐵為基底透過合金設計添加多種元素使材料成為多合金灰口鑄鐵,多合金灰口鑄鐵為高合金化鑄鐵材料並具有高硬化能,加上所添加的元素可在顯微組織中產生片狀石墨組織、高強度麻田散鐵組織、史帝田鐵耐磨相以及碳化鈦/釩的高溫機性穩定析出相,使本材料相較其他氣封材料具有更優異的磨潤性能與高溫強度,極適合使用在轉子引擎中。此外為將本材料應用在轉子引擎中,藉由精密線切割技術製作出精密氣封零件並安裝於轉子引擎上執行性能測試,其測試結果引擎性能明顯優於由球墨鑄鐵所製作之氣封零件,滿足研發需求。Being small volume and highpower, the rotary engine is commonly used to power small to medium UAV. However, to meet high power needs, it is most requested that the rotary engine seals materials have high wear resistance and good performance in high temperature than conventional ones such as stainless steel and nodular graphite cast iron which are no longer effective as needed. Thus, to meet the performance requirements of rotary engine, we add some other elements into gray cast iron to become multi-alloy gray cast iron (MAG cast iron), and yield the microstructure that is characterized by high hardenability, flake graphite, martensite, steadite, and carbide. That consequently makes the MAG cast iron have higher machining strength, better wear resistance and lubricity. We've made rotary engine seals with MAG cast iron by using wire electrical discharge machining (WEDM). Finally, the rotary engines installed with MAG cast iron seals were tested and, from the test results, they revealed more excellent performance than those with nodular graphite cast iron, and met the requirements of the rotary engine development.

    解繳軍種的物料,除了需包裝防護之外,另一個重點就是須標示清楚,因此產生標籤的製作需求。而為方便客戶直接辨識及掃描建檔,除文字的標示之外,還需加上條碼。本研究先簡單介紹幾種常用的標籤紙及碳帶的種類與用途,接著再介紹常見的一維與二維條碼。最後說明自製二維條碼標籤的開發過程中,所遭遇的困難與解決方法。In addition to package protection, clear labeling is critical to ensure good delivery to customers. Consequently, customer and regulatory label demands are on the rise. To meet customers specific label requirements, the barcode labels are required other than text for identification of goods and data establishment. This study briefly introudces commonly used labels, carbon ribbons, one- and two- dimensional barcodes, and how to tackle problems during self-development of 2D barcode.

    隨著3GPP1第五代(fifth generation, 5G)新空中介面(New Radio, NR2)規範[1-2]第一版(Rel-15)的完成,研究下一步重點應該轉向無線行動通訊(Wireless Mobile Communication, WMC)發展。與前幾代產品類似,NR預計在未來十年內逐步展開,從引入創新技術組件到進一步增強功能,以及擴大5G無線接取範圍等等。從更長遠角度來看,我們預期將會有全新的“超越5G”無線接取技術(Radio Access Technology, RAT)出現。重新塑造或重新定義未來無線通訊潛力的新興技術領域,將非人工智慧與機器學習(machine learning, ML)莫屬。在本文中,我們簡要概述了WMC未來發展的一些重要研究面向,並探討WMC系統中不同部門使用AI/ML的潛在影響。Upon completion of the first edition of the 3GPP 5G/NR specification (Rel-15), the following steps of research will emphasize future development of wireless mobile communications (WMC). Like previous generation products, new radio (NR) is expected to be progressively launching, introducing its components of technological innovation and more powerful functions, and extending the range of 5G wireless access. From a long-term perspective, the innovative "Beyond 5G" radio access technology (RAT) is emerging and will be radically redefined and reformed by using artificial intelligence (AI) and machine learning (ML). This paper briefly highlights the critical dimension of future WMC development and investigate the potential impacts of AI and ML on different sectors.
