A Mixed Methods Study On Choice Of Media Influence On Construction Industry Communication, Luciana De Cresce El Debs
A Mixed Methods Study On Choice Of Media Influence On Construction Industry Communication, Luciana De Cresce El Debs
Open Access Dissertations
This study focuses on the use of different communication media for solving problems in the construction industry. The focus of this research is on design-problems containing spatial information and are informally reported between site supervision and design professionals. Due to the fragmented nature of the construction industry, miscommunication is a well-known and common problem. Yet, this fragmented nature is necessary in order to build a complex product involving many different types of professionals. To better understand the issue, this study uses previous literature, such as those published on media richness theory, problem-solving strategy, and construction specific communications, in a three-phased …
Supporting Space Systems Design Via Systems Dependency Analysis Methodology, Cesare Guariniello
Supporting Space Systems Design Via Systems Dependency Analysis Methodology, Cesare Guariniello
Open Access Dissertations
The increasing size and complexity of space systems and space missions pose severe challenges to space systems engineers. When complex systems and Systems-of-Systems are involved, the behavior of the whole entity is not only due to that of the individual systems involved but also to the interactions and dependencies between the systems. Dependencies can be varied and complex, and designers usually do not perform analysis of the impact of dependencies at the level of complex systems, or this analysis involves excessive computational cost, or occurs at a later stage of the design process, after designers have already set detailed requirements, …
Optimal Monitoring And Mitigation Of Systemic Risk In Lending Networks, Zhang Li
Optimal Monitoring And Mitigation Of Systemic Risk In Lending Networks, Zhang Li
Open Access Dissertations
This thesis proposes optimal policies to manage systemic risk in financial networks. Given a one-period borrower-lender network in which all debts are due at the same time and have the same seniority, we address the problem of allocating a fixed amount of cash among the nodes to minimize the weighted sum of unpaid liabilities. Assuming all the loan amounts and cash flows are fixed and that there are no bankruptcy costs, we show that this problem is equivalent to a linear program. We develop a duality-based distributed algorithm to solve it which is useful for applications where it is desirable …
