Searching For Millisecond Pulsars: Surveys, Techniques And Prospects, Kevin Stovall, Duncan R. Lorimer, R. S. Lynch

Physics & Astronomy Faculty Publications

Searches for millisecond pulsars (which we here loosely define as those with periods < 20 ms) in the galactic field have undergone a renaissance in the past five years. New or recently refurbished radio telescopes utilizing cooled receivers and state-of-the art digital data acquisition systems are carrying out surveys of the entire sky at a variety of radio frequencies. Targeted searches for millisecond pulsars in point sources identified by the Fermi Gamma-ray Space Telescope have proved phenomenally successful, with over 50 discoveries in the past five years. The current sample of millisecond pulsars now numbers almost 200 and, for the first time in 25 years, now outnumbers their counterparts in galactic globular clusters. While many of these searches are motivated to find pulsars which form part of pulsar timing arrays, a wide variety of interesting systems are now being found. Following a brief overview of the millisecond pulsar phenomenon, we describe these searches and present some of …

Molecular Fluorescence In The Vicinity Of A Charged Metallic Nanoparticle, H. Y. Chung, P. T. Leung, D. P. Tsai

Physics Faculty Publications and Presentations

The modified fluorescence properties of a molecule in the vicinity of a metallic nanoparticle are further studied accounting for the possible existence of extraneous charges on the particle surface. This is achieved via a generalization of the previous theory of Bohren and Hunt for light scattering from a charged sphere, with the results applied to the calculation of the various decay rates and fluorescence yield of the admolecule. Numerical results show that while charge effects will in general blue-shift all the plasmonic resonances of the metal particle, both the quantum yield and the fluorescence yield can be increased at emission …

Complex Network Analysis, Jian James Ma, Daniel Zeng, Richard A. Huff

Journal of International Technology and Information Management

The clustering coefficient has two definitions that dominate its use, one by Watts and Strogatz, and the second by Newman. It is critical to identify and report the analytic similarities and differences between the two methods in order to give future researchers guidance on the appropriate method to use in their research. This paper reports on an analytical comparison between the two clustering coefficient definitions. We performed the comparison using analytical derivations to show the mathematical relations between the two definitions, the limits on the analysis, and the impact clustering coefficient values derived from the two definitions.

Improving The Efficiency Of Fall Applied N With Cover Crops, Corey Lacey

Theses and Dissertations

Nitrate loss studies in Midwestern tile-drained fields have found that fall applied nitrogen (N) resulted in elevated nitrate concentrations in tile water during both the corn and soybean year of a 2 year rotation. The effectiveness of cover crops to reduce nitrate leaching when N is spring applied has been well demonstrated, however there is a dearth of knowledge on the ability of cover crops to reduce nitrate leaching in a system where N is fall applied. Thus, the objectives of this research were to (i) investigate the efficacy of winter cover crops to reduce nitrate leaching from fall applied …

Comparison Of Emotion Evaluation Perception Using Human Voice Signals Of Robots And Humans, Vesna Kirandziska, Nevena Ackovska

UBT International Conference

Emotion perception is the process of perceiving other people’s emotions. It can be based on their facial expression, movement, voice and other biosignals people emit. The evaluation of human’s emotion is one characteristic of emotions. One of the research areas in Robotics is adapting humanistic behavior in robots. Today many robots are constructed. Some of them can even perceive emotions. In this paper a custom built emotion aware robot that perceives emotion evaluation is used to investigate the similarity and differences of the robot's and human's emotion perception. Voice signals from real human were recorded and the information for the …

Analogy In Elements: Breaking The National Identity, Kujtim Elezi, Nuran Saliu

UBT International Conference

The first aim of this paper is to present the after W.W.II temptation of the Macedonian authors to identify national elements that is Macedonian elements in houses build in Macedonia. After identifying them, the same elements (now national) will be used to declare the national heritage in Macedonian houses. Secondly, we would like to compare the same elements found as Macedonian with other places, like Turkey (involving Bursa, Istanbul and other cities), to see if they really are different as those from houses in Turkey, or there is a similarity between them.

Tuned Mass Damper: An Intelligent Device As A Protection System Instructural Engineering, Feti Selmani, Musa Stavileci

UBT International Conference

Nowadays, destructive environmental forces such as earthquakes, tsunamis and winds accompanied with landslides, have mobilized the minds of the civil engineering communities around the world for finding new and better means for the protection of structures. As it is well known already, the conventional design approach, requires, that the structures passively resist environmental disturbances through a combination of strength, deformability and energy dissipation. Our experience shows that this is neither sufficient nor satisfactory. The basic role of passive energy dissipation devices when incorporated into a structure is to absorb or consume a portion of the input energy, thereby reducing energy …

More-Space – A Simulation Tool For University Room Management, Nicole Nagele-Wild, Š. Emrich, S. Tauböck, Felix Breitenecker, Niki Popper, D. Wiegand

UBT International Conference

As proposed in various studies, educational facilities hold a high potential yield for improvement of room utilization. The goal of the project “MoreSpace” at Vienna University of Technology (TU Vienna) was to develop a hybrid modeling approach which helps to increase the efficiency of the university’s space utilization. Besides coupling of Discrete Event Simulation (DEVS), Agent-based (AB) methods and Cellular Automata (CA), successful deployment of such a model requires a thorough integration within the peripheral system. Which in turn leads to preconditions that have to be met, (e.g. by input - data, visualization of results, dissemination, etc.). This paper covers …

Improving Energy Efficiency In Buildings In Republic Of Kosovo, Ferhat Bejtullahu

UBT International Conference

The building sector is responsible for a substantial part of energy use in Europe and Kosovo. Buildings in Kosovo account for 40 % of the total energy demand, but the building sector pays little or no attention to energy efficiency. The most relevant laws (Energy Efficiency law is in force since July 2011), administrative instructions, regulations and strategic documents in field of energy efficiency are almost completed but implementation and enforcement is still very weak.

Despite all this laws, new regulations and other measures that regulates technical requirements for thermal energy saving and thermal protection, application and management faces difficulties …

Interpretation Of 3d City Models For Sustainable Urban Development, Hebib Alili, Fadil Shehu

UBT International Conference

Many urban or environmental models are determined with the objective to help practitioners and stakeholders in the processes of decision making. The models represented in 3D dimensional geometry are elements of a city and are called 3D models cities. In a wide range, these models are more and more being used for different cities and countries, for purposes beyond simple visualization. Possibility of using of this kind of models, in introducing semantics as geometric aspects, leads into enriching the semantics of 3D city models. Furthermore, in the perspective of sustainable development, cities should be studied in thorough and comprehensive way, …

UBT International Conference

The several Cloud technologies, and their services extends the space of problems that can be solved by them in different fields. The problems are different, but often they represent the same scenario from the perspective of their solution by the cloud technologies and their integrations in different applications. Many situations can be adapted to this scenario: some users send their data into a central Google spreadsheet and a manager follows this spreadsheet. There are specific situations where we are not much interested on the storage of the data, but on the momentarily evidence of them and getting some emergency conclusions. …
