Predicting Rumination From The Five Facets Of Mindfulness, Allen Creamean

Masters Theses

Mindfulness is defined as a process of paying attention to the moment-by-moment experience of thoughts and feelings. It is a non-elaborative, non-judgmental, present-centered awareness in which each thought, feeling or sensation that arises in the attentional field is acknowledged and accepted (Kabat-Zinn, 1990; 1998). The concept of mindfulness adopted in Western therapeutic contexts was derived from Eastern spiritual and philosophical Buddhist teachings. Since its introduction nearly 20 years ago, mindfulness-based treatments have evolved towards altering the relationship between the self and internal/external sensations to reduce multiple forms of psychological and physical morbidity (Bishop et al., 2004). Currently, it is used …

Dynamic Crisis Modifiers: Bp's Gulf Of Mexico Oil Spill, Catherine G. Bocke

Masters Theses

When an organizational crisis emerges, crisis communicators must craft specific messages for their stakeholders and the public. While an organization is attempting to shape how the public perceives it during a crisis, the media work to frame the public's perception of the crisis through news coverage. Situational crisis communication theory (SCCT) is a prescriptive theory that assesses a crisis situation to determine which crisis response will best protect the organization's reputation. Two factors, crisis history and severity, serve as modifiers that can affect the crisis situation, and ultimately influence the best response. BP's Gulf of Mexico oil spill serves as …

Control And Operation Of Multiple Distributed Generators In A Microgrid, Shyam Naren Bhaskara

Masters Theses

"Small sized synchronous generator based distributed generators (DG) often have low start-up times, and can serve as dispatchable generators in a microgrid environment. The advantage is that it allows the power network to operate in a true smart grid environment. The disadvantage is that such DGs typically tend to have low inertia and the prime movers driving these resources need to be controlled in real time for them to operate effectively in islanded, grid-connected modes and during transition from grid-connected mode to islanded mode and vice versa. When multiple DGs are present in the microgrid, the overall control can become …

Cooperative Power Control Approaches Towards Fair Radio Resource Allocation For Wireless Network, Liuju Wu

Masters Theses

"Performance optimization in wireless networks is a complex problem due to variability and dynamics in network topology and density, traffic patterns, mutual interference, channel uncertainties, etc. Opportunistic or selfish approaches may result in unbalanced allocation of channel capacity where particular links are overshadowed. This degrades overall network fairness and hinders a multi-hop communication by creating bottlenecks. A desired approach should allocate channel capacity proportionally to traffic priority in a cooperative manner. This work consists of two chapters that address the fairness share problem in wireless ad hoc, peer-to-peer networks and resource allocation within Cognitive Radio network. In the first paper, …

On The Design Partitioning Of 3d Monolithic Circuits, Luke Maresca

Masters Theses

"Conventional three-dimensional integrated circuits (3D ICs) stack multiple dies vertically for higher integration density, shorter wirelength, smaller footprint, faster speed and lower power consumption. Due to the large through-silicon-via (TSV) sizes, 3D design partitioning is typically done at the architecture-level With the emerging monolithic 3D technology, TSVs can be made much smaller, which enables potential block-level partitioning. However, it is still unclear how much benefit can be obtained by block-level partitioning, which is affected by the number of tiers and the sizes of TSVs. In this thesis, an 8-bit ripple carry adder was used as an example to explore the …
