Joint source-channel decoding for robust transmission of video
Motivated by the need for robust transmission of video, an approach to joint-source channel decoding is presented. While this work is focused on transmission of video, the results are applicable to most forms of multimedia. A general overview of the proposed video coding system is given and its individual components are introduced. Since correct reception of synchronization patterns is essential for successful decoding of compressed bitstreams, detection of a periodically embedded synchronizatio
Model testing of passive site stabilization
Passive site stabilization is a new technology proposed for use in mitigation of liquefaction risk at developed sites. Liquefaction is the rapid loss of strength caused by earthquakes, typically found in saturated sands or loose fills, which causes the formation to flow like later. Liquefaction has been known to be a very costly occurrence claiming many lives, damaging structures and businesses, and costing billions of dollars in repairs; however, sites can be remediated to prevent liquefaction.
Study of Non-Newtonian viscosity and yield stress of blood in a scanning capillary-tube rheometer (A Abstract: The study of hemorheology has been of great interest in the fields of biomedical engineering and medical researches for many years.

Synthesis and characterization of the properties of Ti3SiC2/SiC and Ti3SiC2/TiC composites
In 1996, the ternary compound titanium silicon carbide (Ti3SiC2) was for the first timesynthesized as a single-phase, fully dense compound. Its characterization revealed aunique combination of properties. For its high fracture toughness, low hardness toelastic modulus ratio and excellent damage tolerance, it was dubbed a soft ceramic. Italso displayed good thermal shock and oxidation resistance. In this work, thereinforcement of this material with silicon carbide and titanium carbide particles w
Type 1 diabetic model (A)
Diabetes mellitus is a chronic metabolic disease characterized by the uncoupling of bloodglucose levels and insulin secretion, causing abnormal glycemic excursions. Type 1diabetes is characterized by a complete insulin deficiency. Treatment consists ofattempting to match exogenous insulin delivery to the metabolic needs of the patientduring meals, exercise, and sleep. The objective is to minimize the frequency and severityof glycemic excursions and, more importantly, avoid hypoglycemic episodes.
Implications of resource management in La Parguera, Puerto Rico (The)
A recent rezoning of La Parguera, southwest Puerto Rico, as a tourist zone has resulted in an imbalance between development and appropriate resource management. Development associated with tourism is destroying the sub-tropical dry forest and adding pressure on the marine resources through increased boat traffic and marine structures. Declining water quality and benthic community health are two of the impacts seen in La Parguera associated with these land use changes. This study is three-fold. F
Fault-tolerant distributed shared memory on a broadcast-based interconnection architecture
This thesis focuses on the issue of reliability and fault tolerance in Distributed Shared Memory Multiprocessors, and on the performance impact of implementing fault tolerance protocols that allow for Backward Error Recovery through the use of synchronized checkpointing. High Performance Parallel computing systems that implement Distributed Shared Memory (DSM) require interconnection networks capable of providing low latency and high bandwidth and efficient support for multicast and synchronizat
Numerical simulation of chlorine disinfection processes in non-ideal reactors
The efficacy of disinfection processes in water purification systems is governed by several key factors including reactor hydraulics, disinfectant chemistry and microbial inactivation kinetics. The objective of this work was to develop a computational fluid dynamics (CFD) model to predict flow structure, mass transport, chlorine decay and microbial inactivation in a continuous flow reactor. The significance of this dissertation is that comprehensive 3D numerical model was developed to address al
Novel organic-inorganic hybrid mesoporous materials and nanocomposites
Organic-inorganic hybrid mesoporous materials have been prepared successfully via the nonsurfactant templated sol-gel pathway using dibenzoyl-L-tartaric acid (DBTA) as the templating compound. Styrene and methyl methacrylate polymers have been incorporated into the mesoporous silica matrix on the molecular level. The synthetic conditions have been systematically studied and optimized. Titania based mesoporous materials have also been made using nonionic polyethylene glycol surfactant as the pore
Africa: Peace Corps
offers lessons on stories, letters, photos, and study units from experiences of Peace Corps volunteers across Africa. Topics include folk tales and patterns in them, racial prejudice in South Africa, life in a village of Tanzania, traditional healers and HIV/AIDS, the meaning of wealth, sharing and generosity, what it takes to be a hero, time and punctuality, perspectives of different cultures, and water.
Recording School Desegregation: Conduct Your Own Oral History Project
In this unit, students will research the history of school desegregation, and bring that history to life by listening to oral histories of North Carolinians who lived through desegregation. Students will then become historians, recording their own oral histories with relatives or community members, and reflecting on the experience through writing. The oral histories will be collected into a final project and placed in the school’s library for students and teachers to study in the future.
The Great Depression, the New Deal, and Rural North Carolinians: Analyzing Photographs
In this lesson, students will study photographs of tobacco bag stringers in rural North Carolina, taken to illustrate the report the Virginia-Carolina Service Corporation prepared for Congress in 1939. Students will critically analyze the photographs, making observations about the content of the images, their reactions to them, and what they tell us about the Great Depression. These observations will be structured into a "Know/Want to Know/Learned" chart, in which students will record their prio

DoHistory
This site invites you to explore the process of piecing together the lives of ordinary people in the past. It is an experimental, interactive case study based on the research that went into the book and film A Midwife’s Tale, both based upon the remarkable diary of 18th-century midwife/healer Martha Ballard. Although DoHistory is centered on the life of Martha Ballard, you can learn basic skills and techniques for interpreting fragments that survive from any period in history.
On the Road Again
The movement of people and goods is an important part of the New York State Global History and Geography Curriculum. It is listed as one of the themes that are emphasized in the core curriculum. Students are expected to understand why people migrate and what the impact of migrations has been on people, nations, and regions. Recently, the PBS WIDE ANGLE documentary series created two programs that relate to the movement of people. 'Border Jumpers' (2005) documents migration between countries in A
