Fractal Location and Anomalous Diffusion Dynamics for Oil Wells from the KY Geological Survey
Utilizing data available from the Kentucky Geonet (KYGeonet.ky.gov) the
fossil fuel mining locations created by the Kentucky Geological Survey
geo-locating oil and gas wells are mapped using ESRI ArcGIS in Kentucky single
plain 1602 ft projection. This data was then exported into a spreadsheet
showing latitude and longitude for each point to be used for modeling at
different scales to determine the fractal dimension of the set. Following the
porosity and diffusivity studies of Tarafdar and Roy1 we extract fractal
dimensions of the fossil fuel mining locations and search for evidence of
scaling laws for the set of deposits. The Levy index is used to determine a
match to a statistical mechanically motivated generalized probability function
for the wells. This probability distribution corresponds to a solution of a
dynamical anomalous diffusion equation of fractional order that describes the
Levy paths which can be solved in the diffusion limit by the Fox H function

Art/Sci Nexus, 9 Evenings Revisited
Following the exhibition of Hybrid Bodies at KKW in 2016 Andrew Carnie and I were invited back to act as mentors to a group of young artists and scientists from all over Europe undertaking a week long workshop designed to lead to new art/science collaborations. We were also invited to present the Hybrid Bodies project at a one day public event preceding the workshop
Automatically detecting neighbourhood constraint interactions using comet
The major benet of using events as the basis for our detection system is the clean separation between the neighbourhoods and detector which we can achieve. The detector simply iterates over a set of Neighbourhood objects and checks each for interactions. The acceptance function for the neighbourhood is set to accept any tness. For purposes of detecting an interaction it does not matter whether a move reduces or increases the constraint violations; both indicate that a relationship exists. The simulation is performed in two stages. Starting from a randomly created initial solution a random move from the neighbourhood is chosen, often this will lead to a constraint change and prevent the need for further exploration. For some constraints the chance of randomly selecting a move which would violate it is fairly low and so a more rigourous search is required. If the initial move has not found any interaction then the detector explores every neighbouring state from the current position. If at any stage a change of the constraint violations is detected then the exploration is stopped
Communicative Practices in an American Gamelan Orchestra
Gamelan adalah tradisi musik yang berakar di Indonesia, dipertunjukkan di kepulauan Jawa, Madura, dan Bali dalam upacara-upacara adat dan ritual-ritual agama. Kendati secara tradisional gamelan dimainkan oleh warga pribumi, dengan meningkatnya popularitas budaya etnis Indonesia dalam lingkup Internasional, gamelan baru-baru ini dimainkan pula oleh orang-orang asing. Studi berikut ini merupakan etnografi dari proses komunikasi dalam sebuah Orkestra Gamelan Amerika yang mengidentifikasi dua pertanyaan kunci: (1) Bagaimana gamelan dipelajari di luar konteks sosiokultural orisinalnya? (2) Bagaimana pengetahuan tersebar di antara komunitas yang spesifik ini? Melibatkan kurang lebih 30 anggota (pemusik dan penari) dari sebuah kelompok Gamelan Bali, dengan beragam latar belakang etnis, kebangsaan dan latar belakang musik, penelitian ini menyimpulkan adanya empat praktik komunikasi dalam mempelajari gamelan: (1) Vokalisasi (sebagai metode utama instruktur dalam mengajarkan cara memainkan gamelan); (2) Percakapan informal (sebagai bentuk praktik komunikasi yang memungkinkan anggota kelompok berinteraksi dalam percakapan bebas); (3) Metawacana (suatu proses di mana anggota-anggota senior mencapai keputusan manajemen pertunjukan); dan (4) Blessings, semacam upacara keagamaan memohon restu dari Yang Mahakuasa untuk kesuksesan acara. Keempat praktik komunikasi ini tidak sekadar membantu anggota mempelajari musik tradisional, tetapi juga memungkinkan para musisi tersebut menjadi anggota aktif dalam komunitas yang dikerangka oleh batas-batas kultural. Pada akhirnya, praktik komunikasi semacam ini membantu proses penyebaran pengetahuan di antara anggota-anggota kelompok
Regional Governance and Ecosystem-Based Management of Ocean and Coastal Resources: Can We Get There From Here
Biologic treatments in rheumatoid arthritis and juvenile idiopathic arthritis
A number of biological approaches to the management of inflammtory arthropathies have been explored. These include the development of IL-1 receptor antagonists and TNF antagonists. Four biological agents are currently marketed in Europe. Most studies have revolved around Rheumatoid Arthritis, but an increasing number of studies are now completed or ongoing in the other inflammatory joint diseases. These studies are reviewed in this article with a view to guiding practice and usage in the Maltese Islands.peer-reviewe
Stargazing: Observatories at Gettysburg College, 1874-Present
Astronomy has long been a subject which has attracted the interest of man. Examples of early astronomers can be found in many ancient civilizations, including but not limited to, the Egyptians, the Chinese and the Greeks. As time passed the methods for interpreting the stars and theories that surrounded them changed concordant with the technology available. One of the largest breakthroughs in the world of astronomy was the invention of the telescope in the early seventeenth century. Often mis-attributed to Galileo (who was responsible for building the first reflecting telescope in 1688), the telescope was actually first designed by a Dutch spectacle-maker by the name of Johann Lippershey. Improvements were eventually made upon these designs leading to the creation of government funded observatories, such as the Royal Greenwich Observatory in England, and later private and collegiate research observatories. By the early to mid-nineteenth century, the astronomical craze had begun to develop in America, resulting in the creation of many new observatories in the North and West (now the Mid-West). [excerpt]
