A Generalized Study of the Conjugate and Inner-Product Functions

Wright, Dorothy P. 06 1900 (has links)
The usual practice in any discussion of an inner-product space is to restrict the field over which the inner-product space is defined to the field of complex numbers. In defining the inner-product function, (x,y), a second function is needed; namely the conjugate function (x,y)* so that (x,y) ± (y,x)*. We will attempt to generalize this concept by investigating the existence of a conjugate function defined on fields other than the field of complex numbers and relate this function to an inner-product function defined on a linear space L over these fields.

台灣地區工資結構與工資差異之實証研究

翁郁玲 Unknown Date (has links)
本文以勞動市場基本供需架構,利用行政院主計處人力運用調查資料,探討台灣地區工資結構與工資差異之變化。由基本資料分析發現,不同教育程度間的工資差異持續縮小,而此極現象主要來自供給面與需求面的變動。 在實証上,採用內積(inner product)法、分解(decomposition)法、及特徵根與特徵向量(eigenvalue and eigenvector)法分析發現,供給面之變勁主要是由於教育普及,人人追求高學歷,導致低教育程度者供給減少,高教育程度者供給增加,而此極變動是造成國中、高中程度中工作經驗屬於兩端者與高職、專科、大學程度中工作經驗屬於中間者工資差異縮小的主要因素:前者供給減少故工資上升,後竹供給增加故工資下降,所以工資差異縮小。另外,國中、高中程度中工作經驗屬於中間者與商職、專科、大學程度中工作經驗屬於兩端者工資差異縮小的主要因素,則為需求面之變動所致,而本文採用之需求變數為製造業多因素生產力指數,也因此發現台灣製造業的技術進步是屬於偏非技術性的技術進步,有利於低教育程度者,而不利於高教育程度者,故此項需求面因素縮小了高低教育程度間的工資差異。

Hardware Implementation of Plasma Display Panel Data Dispatcher and Fast Bipolar-valued Inner Product Processor

Hsueh, Ya-Hsin 05 October 2004 (has links)
In this thesis, we firstly present a low-cost plasma display panel (PDP) data dispatcher for image enhancement. By taking advantage of the proposed ADS method with 10 subfields and data reordering, our design can reduce 20% of the PDP dispatcher cost and resolve the ¡§dynamic false contour¡¨ problem. Secondly, a bipolar-valued inner product processor for associative memory neural networks is proposed to compute the inner product of two bipolar-valued vectors. Our analysis shows that the delay of inner product is reduced significantly from O(2n) to O(n). We also propose a 3-dimensional address decoding structure associated with a corresponding data cell encoding arrangement for P+implant ROMs such that the data words are encoded and stored in the ROMs in a natural pattern. Not only is the size of the entire decoder shrunk, the access time and power dissipation is also greatly reduced, which is very suitable to be utilized in implantable devices. Finally, we introduce a multi-parameter implantable neural interface micro-stimulator system, including the external control module, the protocol, and the SOC (system-on-chip) chip. The proposed system is expected to carry out the externally given commands to stimulate the corresponding neural trunks. On the other way around, it can sense and deliver the response of the neural trunks to an external monitoring device in the future.

Hardware Realization of Fast Arithmetic Elements for Signal Processing Applications

Huang, Chenn-Jung 16 May 2000 (has links)
Abstract The tremendous progress in all aspects of signal processing technology has naturally been accompanied by a corresponding development of arithmetic techniques to provide high-speed operations at reasonable complexity. In the past, many architectural design efforts have focused on maximizing performance for frequently executed simple arithmetic operations such as addition and multiplication while left other rarely used operations ignored. In this dissertation, we firstly propose two design approaches for 64-b carry-lookahead adders (CLA) using a two-phase clocking dynamic CMOS logic since fast adders are the key elements in many digital circuits. Secondly, we place emphasis on the inner product operation since it is one of the most frequently used mathematical operations in the computation of digital neural networks. A ratioed 3-2 compressor is also presented to resolve several physical design problems that are not fully considered or implemented in previous research works. Finally we propose several fast 64b/32b integer dividers because the integer division is unavoidable in many important signal-processing applications.
