Unveiling Jewett's Hidden Voice: Discovering The Aborted Future Of Dunnet Landing In The Country Of The Pointed Firs, Katie Mcclelland Dec 2011

Unveiling Jewett's Hidden Voice: Discovering The Aborted Future Of Dunnet Landing In The Country Of The Pointed Firs, Katie Mcclelland

Masters Theses and Doctoral Dissertations

Recent scholarship addresses a deeper significance to Jewett‟s female characters than was previously attributed in canonical history. Jewett imbues her women with complexity, but intentionally avoids portraying her females as disproportionately heroic. Indeed, a pervading recurrence of abortions and otherwise lost children among the predominately female community of Dunnet Landing creates a framework of death by which to interpret the actions and motivations of Jewett‟s characters. My thesis explores the larger metaphor Jewett establishes by juxtaposing the literal abortions of her female characters and the figurative abortion of Dunnet Landing‟s future; moreover, the aborted futures of Jewett‟s female characters mirror …

A Cooperative Game Theoretic Approach For Data Replication In Mobile Ad-Hoc Networks, Dan Hirsch, Sanjay Madria Dec 2011

A Cooperative Game Theoretic Approach For Data Replication In Mobile Ad-Hoc Networks, Dan Hirsch, Sanjay Madria

Computer Science Faculty Research & Creative Works

The mobile computing environment provides many benefits such as ubiquitous access to computing but include constraints on resources such as: Available bandwidth and battery life. Replication is a widely recognized method for balancing the demands of storage space with bandwidth and battery life. We propose a novel scheme that seeks to strategically balance these constrained resources through a cooperative game-theoretic approach for replication in a mobile environment. Our replication strategy relies on the cooperation of the nodes within the network to make replica caching decisions which are spatiotemporally local-optimal for the network from an energy and bandwidth conservation standpoint. in …

Modeling 3d Articulated Motions With Conformal Geometry Videos (Cgvs), Dao T. P. Quynh, Ying He, Xiaoming Chen, Jiazhi Xia, Qian Sun, Steven C. H. Hoi

Research Collection School Of Computing and Information Systems

3D articulated motions are widely used in entertainment, sports, military, and medical applications. Among various techniques for modeling 3D motions, geometry videos (GVs) are a compact representation in that each frame is parameterized to a 2D domain, which captures the 3D geometry (x, y, z) to a pixel (r, g, b) in the image domain. As a result, the widely studied image/video processing techniques can be directly borrowed for 3D motion. This paper presents conformal geometry videos (CGVs), a novel extension of the traditional geometry videos by taking into the consideration of the isometric nature of 3D articulated motions. We …

Stochastic Policy Search For Variance-Penalized Semi-Markov Control, Abhijit Gosavi, Mandar Purohit

Engineering Management and Systems Engineering Faculty Research & Creative Works

The variance-penalized metric in Markov decision processes (MDPs) seeks to maximize the average reward minus a scalar time the variance of rewards. in this paper, our goal is to study the same metric in the context of the semi-Markov decision process (SMDP). in the SMDP, unlike the MDP, the time spent in each transition is not identical and may in fact be a random variable. We first develop an expression for the variance of rewards in the SMDPs, and then formulate the VP-SMDP. Our interest here is in solving the problem without generating the underlying transition probabilities of the Markov …

Linear Precoding For Mimo Multiple Access Channels With Discrete-Constellation Inputs, Mingxi Wang, Weiliang Zeng, Chengshan Xiao

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, we study linear precoding for multiple-input multiple-output (MIMO) multiple access channels (MAC) with discrete-constellation inputs. We derive the constellation-constrained capacity region for the MIMO MAC with an arbitrary number of users. Due to the non-concavity of the objective function, we obtain the necessary conditions for the weighted sum rate (WSR) maximization problem through Karush-Kuhn-Tucker (KKT) analysis. to find the optimal precoding matrices, we propose an iterative algorithm utilizing alternating optimization strategy and gradient descent update. Numerical results show that when inputs are digital modulated signals and the signal-to-noise ratio (SNR) is in the medium range, our proposed …
