A Backend Framework for the Efficient Management of Power System Measurements
Increased adoption and deployment of phasor measurement units (PMU) has
provided valuable fine-grained data over the grid. Analysis over these data can
provide insight into the health of the grid, thereby improving control over
operations. Realizing this data-driven control, however, requires validating,
processing and storing massive amounts of PMU data. This paper describes a PMU
data management system that supports input from multiple PMU data streams,
features an event-detection algorithm, and provides an efficient method for
retrieving archival data. The event-detection algorithm rapidly correlates
multiple PMU data streams, providing details on events occurring within the
power system. The event-detection algorithm feeds into a visualization
component, allowing operators to recognize events as they occur. The indexing
and data retrieval mechanism facilitates fast access to archived PMU data.
Using this method, we achieved over 30x speedup for queries with high
selectivity. With the development of these two components, we have developed a
system that allows efficient analysis of multiple time-aligned PMU data
streams.Comment: Published in Electric Power Systems Research (2016), not available

A Design Program for a Fraternity House Complex for the Development of the South Campus of the University of New Mexico
\u27The problem is to provide facilities for nine fraternities on the south campus of the University of New Mexico. The complex should have facilities for 300 men live-in. Dining facilities for 360 men, with one central kitchen should provide maximum space for special occasions. The possibility of separate dining areas for each fraternity with some type of removable partitions for large gatherings, to be used by one or two fraternities at a time should be investigated
Foreign bank entry - experience, implications for developing countries, and agenda for further research
In recent years, foreign bank participation has increased tremendously in several developing countries. In Argentina, Chile, the Czech Republic, Hungary and Poland, for example, more than fifty percent of banking assets are now in foreign-controlled banks. In Asia, Africa, The Middle East, and the former Soviet Union, the rate of entry by foreign banks has been slower, but the trend is similar. Although the number of countries welcoming foreign banks is growing, many questions about foreign bank entry are still being debated, including: 1) What draws foreign banks to a country? 2) Which banks expand abroad? 3) What do foreign banks do once they arrive? 4) How does the mode of a bank's entry - for example, as a branch of its parent, or as an independent subsidiary company - affect its behavior? The authors summarize current knowledge on these issues. In addition, since the existing literature focuses heavily on industrial countries, they put forth an agenda for further study of the effects of foreign bank entry in developing countries.Financial Intermediation,Banks&Banking Reform,Payment Systems&Infrastructure,Financial Crisis Management&Restructuring,Banking Law,Banks&Banking Reform,Financial Intermediation,Financial Crisis Management&Restructuring,Banking Law,Municipal Financial Management
AGN observations with a less than 100 GeV threshold using H.E.S.S. II
The recent addition of the 28 m Cherenkov telescope (CT5) to the H.E.S.S.
array extended the experiment's sensitivity towards low energies. The lowest
energy threshold is obtained using monoscopic observations with CT5, providing
access to gamma-ray energies below 100 GeV. This is particularly beneficial for
studies of Active Galactic Nuclei (AGN) with soft spectra and located at
redshifts >= 0.5. Stereoscopic measurements with the full array (CT1-5) provide
a better background rejection than CT5 Mono, at a cost of a higher threshold.
We report on the analysis employing the CT5 data for AGN observations with a <
100 GeV threshold. In particular, the spectra of PKS 2155-304 and PG 1553+113
are presented.Comment: In Proceedings of the 34th International Cosmic Ray Conference

A comparison of a first and third year UG enterprise unit: lessons from experiential learning and interdisciplinarity
[EN] Drawing from several years of experience, this work describes lessons learnt in designing, delivering and assessing two interdisciplinary enterprise units offered undergraduate students from any discipline studing at the University of Manchester (UK). Both units are electives (optional). One unit is delivered to first year undergrdaute students whereas the other unit is delivered to third/fourth year undergraduate students. Experiential learning and interdisciplinary cohorts are core aspects of both units. Students work on ‘real-world’ projects to develop a credible and competitive solution within a tight dead-line. In this paper, findings are drawn from data collected from staff and teaching assistants observations, students’ reflective diaries and students’ feedback. Findings showed that in general, students at both levels, year 1 and year 3/4, regarded the experience challenging at first due to the ‘unusual’ learning environment when compared to the education that most students have experienced prior to the units here discussed. However, most students highly regarded the interdisciplinary experiential learning experience. The paper contributes to the growth of knowledge and aids understanding of how experiential learning and interdisciplinarity have been effectively combined and introduced in the university curriculum. Although this works focused on enterprise education the experience-based guidance here described is also applicable to a much wider range of situations and academic areas of study.

Fast Sequence Component Analysis for Attack Detection in Synchrophasor Networks
Modern power systems have begun integrating synchrophasor technologies into
part of daily operations. Given the amount of solutions offered and the
maturity rate of application development it is not a matter of "if" but a
matter of "when" in regards to these technologies becoming ubiquitous in
control centers around the world. While the benefits are numerous, the
functionality of operator-level applications can easily be nullified by
injection of deceptive data signals disguised as genuine measurements. Such
deceptive action is a common precursor to nefarious, often malicious activity.
A correlation coefficient characterization and machine learning methodology are
proposed to detect and identify injection of spoofed data signals. The proposed
method utilizes statistical relationships intrinsic to power system parameters,
which are quantified and presented. Several spoofing schemes have been
developed to qualitatively and quantitatively demonstrate detection
capabilities.Comment: 8 pages, 4 figures, submitted to IEEE Transaction
Towards photonic biosensing using a three-port mach-zehnder interferometer in a silicon nitride platform
Integrated photonics enables sensitive and label-free optical biosensors for the detection of chemical and
biological substances and is therefore promising for future lab-on-chip solutions. In this article we present
our current development of silicon nitride based integrated photonic biosensing devices working at telecom
wavelengths. Our approach of three-port based interferometric sensing circumvents the issues of conventional
Mach-Zehnder interferometers, providing a constant sensitivity, and allowing to use a fixed wavelength sensing
scheme. Preliminary experimental results show that the fabricated devices work as expected from simulations.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
Bank lending to small businesses in Latin America : does Bank origin matter?
In recent years foreign bank participation has increased tremendously in Latin America. Some observers argue that foreign bank entry will benefit Latin American banking systems by reducing the volatility of loans and deposits and increasing efficiency. Others are concerned that foreign banks might choose to extend credit only to certain customers, leaving some sectors-such as small businesses-unserved. The authors examine this issue. Using bank-level data for Argentina, Chile, Colombia, and Peru during the mid-1990s, they empirically investigate whether bank origin affects the share and growth rate of bank lending to small businesses. They find that although foreign banks generally lent less to small businesses (as share of total lending) than private domestic banks, the difference is due primarily to the behavior of small foreign banks. The difference was considerably smaller for large and medium-sized banks. And in Chile and Colombia, large foreign banks might actually lend slightly more (as share of total lending) than large domestic banks.Financial Intermediation,Banks&Banking Reform,Financial Crisis Management&Restructuring,Payment Systems&Infrastructure,Economic Theory&Research,Banks&Banking Reform,Financial Intermediation,Financial Crisis Management&Restructuring,Economic Theory&Research,Banking Law
