Abstract:
In radio astronomy, a key limiting factor to observations made is the available bandwidth of the system. This thesis looks at two different approaches to building ultra-broadband correlators for use in radio astronomy. The first was a 2-20GHz double-sideband complex analogue correlator that was constructed before the work of this thesis. Characterisation tests are performed and a basic calibration is attempted. Both these sets of experiments show good results, with the basic calibration successfully being able to compensate for gain difference between the lags over a reduced bandwidth range us

Abstract:
The present study is an existential phenomenological investigation of the experiences of maternal guilt of five first-time mothers with infant children. Maternal guilt is a powerful, pervasive, and complex phenomenon that effects and is experienced by mothers in different ways. This research explores the experiences of these five mothers in feeling guilt related to being a mother and, using an adapted research methodology utilizing Focusing Technique (Gendlin, 1981), their embodied reflections about a particular memory of feeling maternal guilt. This study utilizes procedures explicated by

碩士<br>國立屏東科技大學<br>機械工程系<br>95<br>This study developed a high efficient auto-focusing measurement system for depth measurement of multi-layer ceramic capacitor. This measuring system integrates auto-focusing vision-based technique with a precise moving X-Y stage. Especially, dual video cameras are used to locate sample position and measure sample depth respectively. One CCD with low magnification rate take a wide field for position-searching, while another CCD with high magnification rate take a micro field for depth-measuring. The principle of depth measurement make use of auto-focusing techni

Abstract:
碩士<br>國立成功大學<br>醫學資訊研究所<br>102<br>Synthetic aperture focusing technique (SAFT) has been proposed to improve the lateral resolution of ultrasound image outside the focal region of the transducer. However, SAFT would result an unexpected artifact image at the region near the focal point of transducer; which is due to the use of a virtue source concept associated with limited numbers of scan lines. The artifact image could be eliminated by using an appropriate time gain compensation (TGC). However, TGC is subjective to users’ settings. To further improve this issue, the present study incorporated

On the surface, Chinese painting utilizes linear stroke techniques in order to construct images, but on a deeper level, these techniques provide the medium through which the artist can express vibrancy and emotion. Indeed, one might say that the use of linear stroke techniques enables the artist to express himself through his art. Jen Po-nien’s paintings have enjoyed an enduring fame, and his techniques and styles have had a profound influence on later generatio

Abstract:
Ο όρος μη γραμμική οπτική (nonlinear optics) αναφέρεται στον κλάδο της φυσικής που μελετά τις μεταβολές που επέρχονται στις οπτικές ιδιότητες της ύλης, όταν αυτή αλληλεπιδρά με ισχυρά ηλεκτρομαγνητικά πεδία. Οι δέσμες λέιζερ (laser) αποτελούν το κατ’ εξοχήν ηλεκτρομαγνητικό πεδίο που χρησιμοποιείται για να προκαλέσει τη μη γραμμική οπτική απόκριση της ύλης, λόγω της ισχυρής ακτινοβολίας. Με την ανακάλυψη του λέιζερ τη δεκαετία του 1960, παράλληλα αναπτύχθηκαν πολλές τεχνικές μέσω των οποίων καθίσταται εφικτός ο προσδιορισμός της μη γραμμικής οπτικής απόκρισης των υλικών.
