On-site wastewater treatment systems (OWTS) work by first storing the wastewater in a septic tank before releasing it to soils for treatment that is generally effective and sustainable. However, it is not clear how the abundance of E. coli changes during its passage through the tank. In this study, which was conducted under the UGA young Scholar Program in summer of 2010, we examined the change...

Reliable data transmission is an important aspect to ensure safety of the electric power grid. In this paper, we propose a non-interactive multi-level key establishment scheme to protect data transmission in hierarchical power grids. Our scheme enables higher-level nodes to hierarchically distribute key materials to lower-level nodes. With the key material, each node is able to locally generate...

Elevated tanks are important structures in storing vital products, such as petroleum products for cities and industrial facilities, as well as water storage. These structures have various types and are constructed in a way that a greater portion of their weight is concentrated at an elevation much about the base. Damage to these structures during strong ground motions may lead to fire or other ...

VLSI technology continues to improve chip density, size, and speed. In the near future, multi-node chips will ooer the only avenue to eeciently harness these increasing resources. Limited oo-chip bandwidth and local memory requirements are two obstacles to multi-chip MIMD nodes. This paper introduces Pica, a ne-grain, message-passing architecture design to overcome these limitations. Using rece...

Founsure is an open-source software library, distributed under LGPLv3 license and implements a multi-dimensional graph-based erasure coding entirely based on fast exclusive OR (XOR) logic. Its implementation utilizes compiler optimizations and the multi-threaded implementation to generate the right assembly code for the given multi-core CPU architectures with vector processing capabilities. Fou...

Advantages, such as thermal storage improvement, are found when using PCMs (Phase Change Materials) in storage tanks. The inclusion of three different types of materials in a 60 l test tank is studied. Two test methodologies were developed, and four tests were performed following each methodology. A thermal analysis is performed to check the thermal properties of each PCM. The distributions of ...

Liquid storage cylindrical containers are built for storing a variety of liquids. The seismic behavior of tanks is, however, quite complex problem. The interaction of tank and liquid can be simplified with the concept of generalized single-degree-of-freedom systems representing the convective, rigid impulsive and flexible impulsive vibration modes. This paper presents the theoretical background...
