Theoretical Analysis Of Dynamic General Equilibrium Model, Mimi Kodheli, Arjeta Vokshi

UBT International Conference

Central Bank is one of the most important institutions of a country because its responsibility is to draw and implement the monetary policy. The central bank, in order to accomplish this responsibility, has to have a clearly defined main objective, the instruments that will use to achieve the objective, and it should be able to make precise or very good forecasts of macroeconomic variables. In order to make these forecasts, the central bank should first of all understand every monetary transmission mechanism and determine the most effective one. The success or non-success of monetary policy, living apart the other factors, …

Efficient Algorithm For Solving 3sum Problem, Muhamed Retkoceri

UBT International Conference

In this paper is presented an algorithm for solving 3SUM problem efficiently in general computation model. The algorithm is based on sorting and splits the task into sub-tasks where this approach enables the algorithm to run concurrently at the high-level of computing. The algorithm is O(n2) and running sequentially achieves at least ~1/5 n2 number of basic necessary accesses of data structures. In this paper is also presented a comparison of running performances in practice between the new algorithm and the current most famous algorithm for 3SUM which is in-place and also based on sorting.

Harmonic Language Arts: Music Inclusion In The Secondary English Language Arts Classroom, Julieanne Sthay

CrissCross

Students are required to take four years of high school English, and the mandatory nature of English coupled with a scripted curriculum negatively impact student interest and motivation. English teachers who incorporate music into their academic teaching are finding music can improve student engagement, motivation, and learning (Goering & Burenheide, 2010). In this qualitative self study of student teaching, I explored questions including whether the addition of music is worthwhile in the English classroom, how it can be done, and what the benefits and drawbacks of doing so are. Based upon field notes, lesson plans, student feedback and research, I …

Carving The Perfect Citizen: The Adventures Of Soviet Pinocchio In Text And On Screen, Rachel Branson

CrissCross

In 1936, Alexei Tolstoy’s The Golden Key, or The Adventures of Buratino was published, heralding the use of children’s literature and fairy tale structure as an ideological and transformative tool for children in the Soviet Union. The Adventures of Buratino, framed by Alexei Tolstoy’s alleged recreation from memory of Carlo Collodi’sThe Adventures of Pinocchio (1883), was a Soviet fairy tale, portraying Buratino as a hero for his fellow puppets in helping to free them from the corrupt and oppressive power of Karabas Barabas, the owner of the puppet theater. While Barabas serves as an embodiment of an exploiter …

Development Of Presumptive And Confirmatory Analytical Methods For The Simultaneous Detection Of Multiple Improvised Explosives, Kelley L. Peters

FIU Electronic Theses and Dissertations

In recent years, there has been a dramatic increase in the use of improvised explosive devices (IEDs) due to ease of synthesis and improved controls placed on commercial/military explosives. Commonly used materials for IED preparations include fertilizers and industrial chemicals containing oxidizers such as ClO₃^-, ClO₄^-, and NO₃^-, as well as other less stable compounds, such as peroxides. Due to these materials having a wide range of volatility, polarity, and composition, detection can be challenging, increasing the amount of time before any analytical information on the identity of the explosive can …

Gauge Theories Of General Relativity, James Thomas Wheeler

James Thomas Wheeler

General relativity can be seen as a gauge theory of the Lorentz, Poincaré, Weyl, de Sitter, or conformal groups. In most of these, there is little or no difference from the standard formulation in Riemannian geometry, but the higher symmetries — de Sitter and conformal — introduce new features and explain old ones. The potential presence of a cosmological constant, the spacetime metric, cosmological dust, symplectic structure, Kähler structure and even the existence of a timelike direction can all be seen to arise from the underlying group structure.

Synthesis And Formation Mechanism Of Cuins2 Nanocrystals With A Tunable Phase, Chao Yu, Linlin Zhang, Long Tian, Dan Liu, Fanglin Chen, Cheng Wang

Faculty Publications

Chalcopyrite CuInS₂ (CIS) hierarchical structures composed of nanoflakes with a thickness of about 5 nm were synthesized by a facial solvothermal method. The thermodynamically metastable wurtzite phase CIS would be obtained by using InCl₃ instead of In(NO₃)₃ as In precursor. The effects of the In precursor and the volume of concentrated HCl aqueous solution on the phases and morphologies of CIS nanocrystals have been systematically investigated. Experimental results indicated that the obtained phases of CIS nanocrystals were predominantly determined by precursor-induced intermediate products. The photocatalytic properties of chalcopyrite and wurtzite CIS in visible-light-driven degradation of …

An Approach To Identity Management In Clouds Without Trusted Third Parties, Akram Y. Sarhan, Leszek T. Lilien

Akram YM Sarhan

The management of sensitive data, including identity management (IDM), is an important problem in cloud computing, fundamental for authentication and fine-grained service access control. Our goal is creating an efficient and robust IDM solution that addresses critical issues in cloud computing. The proposed IDM scheme does not rely on trusted third parties (TTPs) or trusted dealers. The scheme is a multiparty interactive solution that combines RSA distributed key generation and attribute-based encryption. We believe that it will be a robust IDM privacy-preserving solution in cloud computing, because it has the following features: (i) protects sensitive data on untrusted hosts using …

Challenges Associated With Space Weather Analysis And Prediction, John Lanicci

Space Traffic Management Conference

The term “space weather” is typically used to describe environmental conditions in the region extending from the sun’s surface, through the interplanetary medium, to the earth’s magnetic field and upper atmosphere, with a focus on those conditions that can affect the earth, its technological systems, and population. Space weather conditions are monitored continuously by a number of agencies around the world. These agencies use both satellite- and ground-based measurements to build analyses and employ predictive models that form the basis for impacts-based products dealing with myriad users in satellite operations, the utility industry, aviation, and satellite-based communications, to name a …

Weather Research Requirements To Improve Space Launch From Cape Canaveral Air Force Station And Nasa Kennedy Space Center, William P. Roeder, Lisa L. Huddleston, William H. Bauman Iii, Kelly B. Doser

Space Traffic Management Conference

Weather has a large affect on operations at Cape Canaveral Air Force Station (CCAFS) and NASA Kennedy Space Center (KSC). Weather is the leading source of scrubs and delays to space launch from CCAFS/KSC. Weather has an even larger impact on ground processing as space launch vehicles and payloads are prepared in the months before space launch. Many of those operations are very sensitive to weather. In addition, the weather in Florida is notoriously difficult to predict, especially during the summer when rapid deep convection can occur in minutes. Finally, the weather can be extremely subtle in this area during …

The Development Of A Valid And Reliable Biogeochemistry Concept Inventory, Chris Mead

DBER Speaker Series

Concept inventories are a commonly used tool to measure conceptual understanding. To date, concept inventories have been published for geology, chemistry, and biology, but no instrument has been designed to measure conceptual understanding at the intersection of those fields. To fill that gap, we constructed a 32‐item biogeochemistry concept inventory (BGC‐CI). Item response theory analysis, using the Rasch model, shows the BGC‐CI is a reliable and valid tool to measure the biogeochemistry knowledge of science majors. Because biogeochemistry is an interdisciplinary field, we were concerned about the unidimensionality of the instrument. However, our analysis showed the BGC‐CI to be acceptably …

A Methodology For Near-Field Tsunami Inundation Forecasting: Application To The 2011 Tohoku Tsunami, Aditya Riadi Gusman, Yuichiro Tanioka, Breanyn Macinnes, Hiroaki Tsushima

All Faculty Scholarship for the College of the Sciences

Existing tsunami early warning systems in the world can give either one or a combination of estimated tsunami arrival times, heights, or qualitative tsunami forecasts before the tsunami hits near-field coastlines. A future tsunami early warning system should be able to provide a reliable near-field tsunami inundation forecast on high-resolution topography within a short time period. Here we describe a new methodology for near-field tsunami inundation forecasting. In this method, a precomputed tsunami inundation and precomputed tsunami waveform database is required. After information about a tsunami source is estimated, tsunami waveforms at nearshore points can be simulated in real time. …

Curie Temperatures Of Titanomagnetite In Ignimbrites: Effects Of Emplacement Temperatures, Cooling Rates, Exsolution, And Cation Ordering, Mike J. Jackson, Julie A. Bowles

Geosciences Faculty Articles

Pumices, ashes, and tuffs from Mt. St. Helens and from Novarupta contain two principal forms of titanomagnetite: homogeneous grains with Curie temperatures in the range 350–500°C and oxyexsolved grains with similar bulk composition, containing ilmenite lamellae and having Curie temperatures above 500°C. Thermomagnetic analyses and isothermal annealing experiments in combination with stratigraphic settings and thermal models show that emplacement temperatures and cooling history may have affected the relative proportions of homogeneous and exsolved grains and have clearly had a strong influence on the Curie temperature of the homogeneous phase. The exsolved grains are most common where emplacement temperatures exceeded 600°C, …

An Agile Implementation Within A Medical Device Software Organisation, Martin Mchugh, Fergal Mc Caffery, Garret Coady

Conference papers

Three surveys conducted over a 6 year period revealed that medical device software organisations have difficulties in the area of requirements management, namely accommodating changes in requirements. Medical device software is traditionally developed in accordance with a plan driven software development lifecycle (SDLC). These SDLCs are rigid and inflexible to changes once the requirements management stage has been completed. Agile methods are gaining momentum in non-regulated industries but as of yet, the adoption of these methods in regulated industries such as the medical device software domain remains low. This study presents an implementation of agile methods within a medical device …

Ahmad Talaei

Modified IS (Iranian Sun) plasma focus (10 kJ,15 kV, 94 μF, 0.1 Hz) has been used to produce the short-lived radioisotope 13N (half-life of 9.97 min) through 12C(d,n)13N nuclear reaction. The filling gas was 1.5–3 torr of hydrogen (60%) deuterium (40%) mixture. The target was solid nuclear grade graphite with 5 mm thick, 9 cm width and 13 in length. The activations of the exogenous target on average of 20 shots (only one-third acceptable) through 10–13 kV produced the 511 keV gamma rays. Another peak found at the 570 keV gamma of which both was measured by a NaI portable …

Control Power In Perfect Controlled Teleportation Via Partially Entangled Channels, Xi-Han Li, Shohini Ghose

Physics and Computer Science Faculty Publications

We analyze and evaluate perfect controlled teleportation via three-qubit entangled channels from the point of view of the controller. The key idea in controlled teleportation is that the teleportation is performed only with the participation of the controller. We calculate a quantitative measure of the controller's power and establish a lower bound on the control power required for controlled teleportation. We show that the maximally entangled Greenberger-Horne-Zeilinger state is a suitable channel for controlled teleportation of arbitrary single qubits-the controller's power meets the bound and the teleportation fidelity without the controller's permission is no better than the fidelity of a …
