Curbing Energy Sprawl With Microgrids, Sara C. Bronin

Cornell Law Faculty Publications

Energy sprawl - the phenomenon of ever-increasing consumption of land, particularly in rural areas, required to site energy generation facilities - is a real and growing problem. Over the next twenty years, at least sixty-seven million acres of land will have been developed for energy projects, destroying wildlife habitats and fragmenting landscapes. According to one influential report, even renewable energy projects - especially large-scale projects that require large-scale transmission and distribution infrastructure - contribute to energy sprawl. This Article does not aim to stop large-scale renewable energy projects or even argue that policymakers focus solely on land use in determining …

Processing And Composition Effects On The Fracture Behavior Of Spray-Formed 7xxx Series Al Alloys, Mala M. Sharma, Constance W. Ziemian, Timothy J. Eden

Faculty Journal Articles

The fracture properties of high-strength spray-formed Al alloys were investigated, with consideration of the effects of elemental additions such as zinc,manganese, and chromium and the influence of the addition of SiC particulate. Fracture resistance values between 13.6 and 25.6 MPa (m)^1/2 were obtained for the monolithic alloys in the T6 and T7 conditions, respectively. The alloys with SiC particulate compared well and achieved fracture resistance values between 18.7 and 25.6 MPa (m)^1/2. The spray-formed materials exhibited a loss in fracture resistance (KI) compared to ingot metallurgy 7075 alloys but had an improved

A Case Study Of The Mathematical Learning Of Two Teachers Acquiring Mathematical Knowledge For Teaching, David R. Hartman

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This study offers an analysis of the learning of practicing teachers as they acquire a deeper knowledge of mathematics. While some professional developers have shifted part of their focus to helping practicing teachers acquire a deeper knowledge of mathematics (e.g., Stein & Silver, 1996), the results from studies often describe what translates from the professional development experience into classroom practice and measureable gains in student achievement (e.g., Desimone et al., 2002). Studies showing improvements in pedagogy and student learning are important. However, studying what teachers are learning and how they learn is important in developing understanding of the content and …

Ultrasonic Activation Of Triacetone Triperoxide, Latravia R. Dobson

Department of Chemistry: Dissertations, Theses, and Student Research

Triacetone triperoxide (TATP) is an organic peroxide that has received widespread attention in recent years. TATP is a ketone peroxide with a high active oxygen content. It is relatively shock sensitive, with explosive decomposition easily initiated, and is therefore considered a primary explosive. However, TATP is also a powerful explosive possessing about 83 % of the power of TNT. TATP can be prepared quickly and easily from inexpensive household chemicals in the absence of any specialized facilities, making it the explosive of choice for modern day terrorists. TATP poses a major challenge for security and law enforcement services around the …

Synthesis And Catalytic Activity Of Nanostructured Cerium Oxide, Neil J. Lawrence

Department of Chemistry: Dissertations, Theses, and Student Research

Cerium oxide (ceria, CeO_2-x where x is 0 to 0.5) has been one of the most widely used heterogeneous catalysts particularly in three way catalytic converters. Most of the catalytic traits can be attributed to two properties of ceria: first, the high mobility and storage capacity of oxygen within the lattice; second, the ease with which cerium changes between Ce³⁺ and Ce⁴⁺ states. These properties, combined with the abundance of cerium on earth, make ceria a low-cost highly effective alternative to noble metal catalysts. Recent research has been focused on the nanoscale properties of ceria.

This paper, however, investigates the trajectories of two OSS-based information systems (IS) implementation projects in a developing country (DC) context with the aim to uncover the practice-based learning and resource sharing evident among locally situated and globally dispersed developers and users. The result of the interpretative case study research shows that the OSS philosophy and practice of software development, implementation and ownership, facilitates for the emergence of …

Administrative Law, Martin M. Wilson, Jennifer A. Blackburn

Mercer Law Review

Even in tough economic times, the work of administrative agencies seems to continue with particularly robust growth at the state level. The number of contested agency cases seems to be rising, even those involving the most trivial details. Although the idea of more government is not fashionable in most corridors, higher levels of activity by existing governmental agencies will be the norm until the state's economic picture achieves measurable improvement.

This Article is a survey of cases from the Georgia Supreme Court and Georgia Court of Appeals from June 1, 2009 through May 31, 2010. The cases chosen for review …

Tracing Water Sources Of Terrestrial Animal Populations With Stable Isotopes: Laboratory Tests With Crickets And Spiders, Kevin E. Mccluney, John L. Sabo

Biological Sciences Faculty Publications

Fluxes of carbon, nitrogen, and water between ecosystem components and organisms have great impacts across levels of biological organization. Although much progress has been made in tracing carbon and nitrogen, difficulty remains in tracing water sources from the ecosystem to animals and among animals (the ‘‘water web’’). Naturally occurring, nonradioactive isotopes of hydrogen and oxygen in water provide a potential method for tracing water sources. However, using this approach for terrestrial animals is complicated by a change in water isotopes within the body due to differences in activity of heavy and light isotopes during cuticular and transpiratory water losses. Here …

A Genetic Algorithm For Multiobjective Hard Scheduling Optimization, Elías Niño, Carlos Ardila, Alfredo J. Perez, Yexid Donoso

Computer Science Faculty Publications

This paper proposes a genetic algorithm for multiobjective scheduling optimization based in the object oriented design with constrains on delivery times, process precedence and resource availability. Initially, the programming algorithm (PA) was designed and implemented, taking into account all constraints mentioned. This algorithm’s main objective is, given a sequence of production orders, products and processes, calculate its total programming cost and time.
Once the programming algorithm was defined, the genetic algorithm (GA) was developed for minimizing two objectives: delivery times and total programming cost. The stages defined for this algorithm were: selection, crossover and mutation. During the first stage, the …

Foreigners' Archive: Contemporary China In The Blogs Of American Expatriates, Qi Tang, Chin-Chung Chao

Communication Faculty Publications

This study scrutinized blogs written by American expatriates in twenty-firstcentury China. The primary objectives were to explore how China is represented in such blogs and to understand the discursive processes through which the American bloggers utilize the blogging technology to narrate their perceptions of the Chinese realities. Drawing on the postcolonial and discursive perspectives, we have determined that the blogs examined here consist of a distinct discursive space of cultural representation and contestation. They were also interpreted as a digital extension of conventional Euro-American travel writing as they share with the genre a set of rhetorical conventions and face the …
