Song, Yaohua (2012-10-19)Nowadays, TV advertising is an important part of our daily life. However, it is usually hard for organizations that produce and pay for the advertisements to confirm whether their commercials are broadcasted as required ...
-
Uppal, Momin Ayub (2009-06-02)Recent information theoretical results indicate that dirty-paper coding (DPC) achieves the entire capacity region of the Gaussian multiple-input multiple-output (MIMO) broadcast channel (BC). This thesis presents practical ...
-
Uppal, Momin Ayub (2011-10-21)The area of cooperative communications has received tremendous research interest in recent years. This interest is not unwarranted, since cooperative communications promises the ever-so-sought after diversity and ...
-
Cheng, Szeming (Texas A&M University, 2005-11-01)Source coding and channel coding are two important problems in communications. Although side information exists in everyday scenario, the effect of side information is not taken into account in the conventional setups. ...
-
Raja, Nouman Saeed (Texas A&M University, 2005-02-17)This thesis proposes a framework for combined source-channel coding under power and bandwidth constrained noisy channel. The framework is then applied to progressive image coding transmission using constant envelope M-ary ...
-
Pi, Pengcheng (2022-04-04)Computer vision has made massive progress in recent years, thanks to hardware and algorithms development. Most methods are performance-driven meanwhile have a lack of consideration for energy efficiency. This dissertation ...
-
Garg, Vineet (2019-04-16)Video object segmentation is gaining increased research and commercial importance in recent times from no checkout lines in Amazon Go stores to autonomous vehicles operating on roads. Efficient operation for such use cases ...
-
Jiang, Ziyu (2022-12-10)Contrastive Learning, a class of self-supervised learning methods, learns strong visual representations by pulling the same images to be similar while pushing different images to be distinct. Though contrastive learning ...
-
Lan, Ching Fu (Texas A&M University, 2006-04-12)In ShannonÂs seminal paper, ÂA Mathematical Theory of CommunicationÂ, he defined ÂChannel Capacity which predicted the ultimate performance that transmission systems can achieve and suggested that capacity is ...

Yuan, Peng (2014-06-03)A successful craniomaxillofacial (CMF) surgery depends not only on surgical techniques, but also on an accurate surgical plan. However, the traditional planning methods have proven problematic. Towards this end, we have ...
-
Chang, Yu-Bing (2012-07-16)In the field of craniomaxillofacial (CMF) surgery, surgical planning is an important and necessary procedure due to the complex nature of the craniofacial skeleton. Computed tomography (CT) has brought about a revolution ...
-
Kang, Inuk (2022-06-03)Currently, research on securing safety by unmanned systems is being actively conducted. Development is underway to reduce costs and secure worker safety by filling safety-related personnel’s blind spots and reducing their ...
-
Li, Hang (2016-07-01)It is in recent years that harvesting energy from ambient energy sources (e.g., solar, wind, or vibration) has been commercialized, which is a promising technique to fulfil sustainable operations for many kinds of electrical ...
-
Chanda, Deepankar (2020-11-23)Image inpainting is the task of filling missing regions in a masked image. Modern approaches for inpainting are unable to effectively utilize contextual information present within the image which results in color, texture ...
-
Liu, Hui (Texas A&M University, 2004-09-30)The presence of dispersive fading and inter-carrier interference (ICI) constitute the major impediment to reliable communications in orthogonal frequency-division multiplexing (OFDM) systems. Recently iterative (``Turbo'') ...
