Item type:Item, Cooperative spectrum sensing method and system for locationing primary transmitters in a cognitive radio system(2014-12-09) ;Wu Sau-Hsuan ;Huang Din-HwaKo Chun-HsienIn a cooperative spectrum sensing method and system for locationing primary transmitters, each of secondary users transmits to a corresponding one of cognitive radio (CR) base station location information thereof and a received signal strength indicator (RSSI) value generated thereby in response to sensing power signals from the primary transmitters. The CR base stations transmit the location information and the RDDI values of the secondary users to a data fusion center such that the data fusion center obtains the number and locations of the primary transmitters based on the location information and the RSSI values received thereby using a learning algorithm to thereby reconstruct a power propagation map of the primary transmitters.Item type:Item, Method for estimating capacitance weight errors and successive approximation analog to digital converter using the same(2014-12-09) ;Hong Hao-ChiaoHsieh Tsung-YinA successive approximation (SA) analog-to-digital converter (ADC) capable of estimating its own capacitance weight errors includes a comparator, a capacitor set, a switch set and a controller. The capacitor set includes a primary capacitor array including a plurality of binary-weighted capacitors, and a secondary capacitor array including a plurality of binary-weighted capacitors with known capacitance weights. The controller controls the switch set and repeats the steps of pre-charging the primary capacitor array, redistributing electric charges to the primary capacitor array and the secondary capacitor array, and performing a successive approximation binary searching on the primary capacitor array and the secondary capacitor array to calculate the capacitance weight error of each capacitor in the primary capacitor array. The calculated capacitance weight errors are used for calibrating the output of the successive approximation ADC.Item type:Item, Method of semiconductor manufacturing process(2014-12-09) ;Wu YewChung Sermon ;Wang Bau-MingHsiao Feng-ChingThe present invention related to a method for manufacturing a semiconductor, comprising steps of: providing a growing substrate; forming a semiconductor substrate on the growing substrate; forming a first structure with plural grooves and between the growing substrate and the semiconductor substrate; and changing the temperature of the growing substrate and the semiconductor substrate.Item type:Item, Microphone array structure able to reduce noise and improve speech quality and method thereof(2014-12-09) ;Bai Mingsian R.Chen Chun-HungThe present invention discloses a microphone array structure able to reduce noise and improve speech quality and a method thereof. The method of the present invention comprises steps: using at least two microphone to receive at least two microphone signals each containing a noise signal and a speech signal; using FFT modules to transform the microphone signals into frequency-domain signals; calculating an included angle between a speech signal and a noise signal of the microphone signal, and selecting a phase difference estimation algorithm, a noise reduction algorithm or both to reduce noise according to the included angle; if the phase difference estimation algorithm is used, calculating phase difference of the microphone signals to obtain a time-space domain mask signal; and multiplying the mask signal and the average of the microphone signals to obtain the speech signals of the microphone signals. Thereby is eliminated noise and improve speech quality.Item type:Item, Method for visualizing a complicated metro map in a limited displaying area(2014-12-09) ;Wang Yu-ShuenChi Ming-TeThe prevented invention provides a method to visualize complicated metro maps in a limited displaying area, in which the route to the passenger's destination is highlighted. In order to achieve high readability, it sets 1) the distance between neighboring stations to be equal, 2) the transportation lines to lie in octilinear directions, 3) the angles of incident edges at each station to be maximized, and 4) the station positions to be inside the displaying area. It also labels the names of stations that passenger will pass by to make the route navigation easy and intuitive.Item type:Item, 開幕講座(2014-12-10) ;Library圖書館快分享啦!; 講座:用iPad彩繪夢想 怪獸老爸-黃世明 12/10(三)12:10-13:10 圖書館2樓大廳; 免報名+免費參加+供餐點講座; 網路圖文作家,怪獸老爸,著有 「帶著iPad玩畫畫!塗鴉創意50招」等書。 12/10,對於圖文創作有興趣的同學,千萬別錯過了!Item type:Item, Item type:Item, Efficient Optical Trapping of CdTe Quantum Dots by Femtosecond Laser Pulses(2014-12-11) ;Chiang, Wei-Yi ;Okuhata, Tomoki ;Usman, Anwar ;Tamai, NaotoMasuhara, HiroshiThe development in optical trapping and manipulation has been showing rapid progress, most of it is in the small particle sizes in nanometer scales, substituting the conventional continuous-wave lasers with high-repetition-rate ultrashort laser pulse train and nonlinear optical effects. Here, we evaluate two-photon absorption in optical trapping of 2.7 nm-sized CdTe quantum dots (QDs) with high-repetition-rate femtosecond pulse train by probing laser intensity dependence of both Rayleigh scattering image and the two-photon-induced luminescence spectrum of the optically trapped QDs. The Rayleigh scattering imaging indicates that the two-photon absorption (TPA) process enhances trapping ability of the QDs. Similarly, a nonlinear increase of the two-photon-induced luminescence with the incident laser intensity fairly indicates the existence of the TPA process.Item type:Item, 具有由資料控制之電源供應的靜態隨機存取記憶體(2014-12-11) ;莊景德 ;楊皓義 ;夏茂墀 ;林勇維盧建宇Item type:Item, Characterizing the electrical properties of raised S/D junctionless thin-film transistors with a dual-gate structure(2014-12-11) ;Cheng, Ya-Chi ;Chen, Hung-Bin ;Su, Jun-Ji ;Shao, Chi-ShenWang, Cheng-PingThis letter demonstrates a p-type raised source-and-drain (raised S/D) junctionless thin-film transistors (JL-TFTs) with a dual-gate structure. The raised S/D structure provides a high saturation current (> 1 mu A/mu m). The subthreshold swing (SS) is 100 mV/decade and the drain-induced barrier lowering (DIBL) is 0.8 mV/V, and the I-on/I-off current ratio is over 10(8) A/A for L-g = 1 mu m. Using a thin channel structure obtains excellent performance in the raised S/D structure. Besides the basic electrical characteristics, the dual-gate structure can also be used to adjust V-th in multi-V-th circuit designs. This study examines the feasibility of using JL-TFTs in future three-dimensional (3D) layer-to-layer stacked high-density device applications.Item type:Item, SYSTEM ARCHITECTURE AND METHOD FOR SERVICE CONTINUITY IN HETEROGENEOUS WIRELESS NETWORK(2014-12-11) ;TSENG CHIEN-CHAOCHAN MIN-CHENGThe present invention provides a system architecture and a method for service continuity in heterogeneous wireless networks, which comprises a handover decision module and a session continuity module.
