Merger Announcement Returns with Preparations
<p>This paper analyzes the relationship between the merger announcement returns and the bidding firms' preparations for mergers. In this study, merger preparations are defined as bidding firms' adaptive actions of changing their executives prior to mergers. An analysis of the relative effectiveness …

Photophysics of Phenylene Vinylene Polymers and Oligomers: The Influence of Nanocrystalline Domains
This study looks at the nature of excited states and their photodynamics in phenylene vinylene molecules. Poly-p-(phenylene vinylene) (PPV), poly[(2-methoxy-5-hexyloxy-p-phenylene)vinylene] (MH-PPV), and 1,4-distyrylbenzene (DSB), a small molecule analog of PPV, are studied using various …

Signaling, Extended Deterrence, and Regional Conflict Escalation: A Game Theory Model
In my dissertation I seek to determine the conditions of regional conflict escalation. In particular, I pose two questions in this dissertation: first, why do small states decide to fight against relatively more powerful states in spite of very low likelihood of winning?; and second, once regional …

Effective Green and Ampt parameters for two layered soils
Green-Ampt method is a physically based model for partitioning rainfall into surface runoff and infiltration. This method is widely used in infiltration practice because of its simplicity and the ease of obtaining required hydraulic soil properties. The method assumes that soil is homogeneous, …

Localization, escape rate and delocalization in kinked ratchet potentials
The particle localization in ratchet potentials with segments of reverse directions, or kinked ratchets, is computationally studied. Kinks localize a particle on on-off pulsating ratchet potentials, forming stable points in the effective potential. Analogous Kramers rate for transition between …

Dynamic Planning and control Methodology : understanding and managing iterative error and change cycles in large-scale concurrent design and construction projects
Construction projects are uncertain and complex in nature. One of the major driving forces that may account for these characteristics is iterative cycles caused by errors and changes. Errors and changes worsen project performance and consequently, cause schedule and cost overruns to be prevalent. …
