New submissions to the thesis/dissertation collections are added automatically as they are received from the Graduate School. Currently, the Graduate School deposits all theses and dissertations from a given semester after the official graduation date. This means that there may be up to a 4 month delay in the appearance of a given thesis/dissertation in DRUM.

More information is available at Theses and Dissertations at University of Maryland Libraries.

    VIDEO TEMPLATE MATCHING ALGORITHM FOR CONSTRUCTION PROJECTS---A HADAMARD DOMAIN APPROACH
    (2014) Yang, Xue; Haghani, Ali; Civil Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    One exciting prospect of modern construction projects is the potential for multimedia techniques, such as real-time video, to significantly affect the way of project delivery. Of all techniques in real-time video processing, template-matching plays the most essential role because of its high computational complexity and its ability to deal with considerable redundancy. However, commonly used template-matching techniques in spatial domain cannot meet all of the requirements for all construction applications. Some methods have heavy computational burden, others suffer from inadequate accuracy. Therefore, an adjustable template-matching capable of meeting all requirements is an exciting prospect. The proposed template-matching algorithm utilizes special relation between associated Hadamard determinants. Results indicate the proposed algorithm outperforms many popular algorithms without increasing computational complexity level. Moreover, the algorithm is capable of adjusting three parameters accordingly to meet different construction-related applications.

    Construction Project Organizational Structuring
    (2005-04-20) Salgado, Carlos; Baecher, Gregory B; Civil Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    This dissertation presents an extended research study of project organizational structuring design, using Mintzberg's design parameters of organization and Lucas' IT-enabled variables on construction building project organizations. To the design parameters of unit grouping, unit size, liaison devices, planning and control systems, decision-making system and design of positions, this dissertation study simultaneously considers virtual components, technological leveling, technological matrixing, electronic linking and communications. This study used Yin's multiple case holistic design approach for this extended research study with data from major successful building construction projects to illustrate the use of this extended view and compare its findings. Based on this extended research study, this dissertation develops a practical methodology for construction project organizational structuring design. Furthermore, this dissertation applied Robbins' measures of organization structure (complexity, formalization and centralization) for corroboration.
