Item A preliminary interindustry model for West Texas(Texas Tech University, 1971-05) McCray, William ChesterNot availableItem An input-output analysis of selected rural elementary schools in West Texas(1986-05) Desrosiers, Ellen S.; Sparkman, William E.; Beckner, Weldon E.; Cornett, Joe D.; Jonish, James E.; Mehaffie, ShamusNot AvailableItem Economic impacts of the hotel industry in Texas: An input-output analysis(2012-08) Kim, Hyojin; Goh, Ben K.; Stout, Betty L.; Yuan, JingxueBy identifying the economic structure of relations between the hotel industry and other industries within the State of Texas, this study examined data from 2009 from the Minnesota Implan Group to determine whether or not the hotel industry was a contributing industry to the State of Texas. Unlike a simple and straightforward ad-hoc multiplier focusing on an understanding of temporary economic impacts at a specific time, the input-output analysis created by Leontief comprehensively and systematically identifies a picture of producing and purchasing goods and services between entire industrial sectors in an economic system of a regional or national level. Therefore, the input-output analysis model, which provides quantified reliable data for policymakers, was applied to this study. The findings of this study were as follows: 1) Even though the hotel industry was helpful to the Texas economy, it made a small contribution to the state compared to manufacturing and other industries according to multipliers of output, labor income, value-added, and employment from the input-output analysis. 2) After aggregation into 21 and 20-related sectors based on the ISIC and NAICS, the hotel-related industry became somehow less interdependent when compared with other-related industries, such as manufacturing-related, construction, or finance and insurance-related sectors. However, it is more interdependent on the rest of the Texas economy than the wholesale and retail trade sectors. 3) Interestingly, while the hotel industry generated more labor income and employment than did the other accommodation industries, the other accommodation sectors created more output and value-added than did the hotel industry. With this quantified economic information from the results, it is anticipated to be helpful to future plans or policies associated with the hotel industry.Item Estimating linear functionals of indirectly observed input functionals(Texas Tech University, 2004-08) Lee, Eun-JooWe consider the usual estimator of a linear functional of the unknown input function in indirect nonparametric regression models. The unknown regression function which is the parameter of interest, is infinite dimensional. Since the output is an integral transform of the input, this transformation must be inverted to recover the input. Because such an inversion is, in general, unbounded, regularization of the inverse will be required. Since a function in a separable Hilbert space has a Fourier expansion in an orthonormal basis the Fourier coefficients will be estimated in order to recover the input. Regularization of the inverse boils down to tapering the expansion with the estimated Fourier coefficients, which would otherwise not converge. In any case this shows that estimating Fourier coefficients and linear functionals in general is an important issue. It is surprising to see that the traditional estimator of the Fourier coefficients is not asymptotically efficient according to the Hajek-LeCam convoluteion theorem. Since this estimator, however, is -y/n-consistent, it can be improved in an asymptotic sense. A simulation study is included to establish the practical effect of this asymptotic result. In this dissertation, the theory is presented in a self-contained manner. This means that a complete derivation of theorems like Hajek's convolution theorem and the theorem on possible improvement of n-consistent estimators will be given.Item High performance PCI-compatible DDR SDRAM controller and inter-processor logic design for quad-DSP board(Texas Tech University, 2004-08) Mane, Amitkumar TulshidasThe focus of this thesis is on the logic design needed for Quadia, a signal processing board developed at Innovative Integration, Inc. Quadia is an ideal platform for integrating high performance DSPs and I/O technologies into advanced signal processing, data acquisition and real-time applications such as telecom, RADAR, SONAR and wireless communications. The logic design developed in this thesis for Quadia includes a Global Memory Pool Controller and an Inter-processor FIFO Mesh. The Global Memory Pool Controller provides access to a 512 Mbit Global Memory Pool over the PCI bus. Quadia is a multi-processor board, and inter-processor communication is the most crucial aspect of this design. The inter-processor FIFO Mesh provides extreme flexibility and low latency for very complex exchanges of bulk data and control messages between DSPs. Each DSP on the board has a private link mapped to its EMIF-B. Using this FIFO Mesh, user software can implement DMA-driven packet-based inter-processor communication. All the logic needed for this board is implemented in a Xilinx FPGA, the VirtexII-Pro XC2VP20.
