Selective Personalization And Group Profiles For Improved Web Search Personalization, Samira Karimi Mansoub, Gönenç Ercan, İlyas Çi̇çekli̇

Turkish Journal of Electrical Engineering and Computer Sciences

Personalization is a common technique used in Web search engines to improve the effectiveness of retrieval. While personalizing some queries yields significant improvements in user experience by providing a ranking in line with the user preferences, it fails to improve or even degrades the effectiveness for less ambiguous queries. A potential personalization metric could improve search engines by selectively applying personalization. One such measure, click entropy uses the query history and the clicked documents for the query, which might be sparse for some queries. In this article, the topic entropy measure is improved by integrating the user distribution into the …

An Alternative Method Of Biomedical Signal Transmission Through The Gsm Voice Channel, Seyedmohsen Dehghan, Mehmet Kaya

Turkish Journal of Electrical Engineering and Computer Sciences

In this work, a new solution for online and accurate biomedical data transmission is presented. For this purpose, a global system for mobile (GSM) communication voice channel is, for the first time, used as a communication link between the patient and healthcare provider. Biomedical signals are converted into speech-like signals before being transferred over a GSM voice channel. On the receiver side, speech-like symbols are stored in a symbols bank, and constructed using random stochastic signals. On the receiver end, the index of the symbol with the most similarity to the received signal is selected as the identified sample. This …

Wavelength Sensitivity Of Indium Tin Oxide On Surface Plasmon Resonance Angles, Antonio Ruiz, Carlos Villa Angulo, Ivan Olaf Hernandez-Fuentes

Turkish Journal of Electrical Engineering and Computer Sciences

Surface plasmon resonance (SPR) is a charge-density oscillation that occurs when a beam of p-polarized monochromatic light impinges with a greater angle than the critical angle in a dielectric-metal interface. Because of the high losses related to metals, the generated surface plasmon waves propagate with high attenuation in the visible and near-infrared spectral regions in most of the dielectric-metal interfaces. An alternative to reduce such losses is to use a transparent indium tin oxide (ITO) film. In this paper, we compared theoretical calculations and experimental measurements of the SPR angle $\theta_{SPR}$ on the interfaces of a borosilicate prism (Bp) and …

Assessment Of Pretreatments On Drying Kinetics And Quality Characteristics Of Thin-Layer Dried Red Pepper, Bi̇ge İncedayi

Turkish Journal of Agriculture and Forestry

In this study, the effect of pretreatments (hot water blanching, microwave blanching, and ohmic heating (OH)) on the drying kinetics and quality characteristics of red pepper, dried at 60 and 70 °C, was investigated. The drying times varied between 205-290 min, depending on the pretreatment and temperature applied. The drying rate also changed based on the pretreatment and the falling rate period was observed. Fitted to the experimental data were 4 mathematical models and the logarithmic model was found to be the best for all of the samples. Effective moisture diffusivity values obtained from Fick?s second law of diffusion ranged …

Modelling Interactions Among Offenders: A Latent Space Approach For Interdependent Ego-Networks, Isabella Gollini, Alberto Caimo, Paolo Campana

Articles

Illegal markets are notoriously difficult to study. Police data offer an increasingly exploited source of evidence. However, their secondary nature poses challenges for researchers. A key issue is that researchers often have to deal with two sets of actors: targeted and non-targeted. This work develops a latent space model for interdependent ego-networks purposely created to deal with the targeted nature of police evidence. By treating targeted offenders as egos and their contacts as alters, the model (a) leverages on the full information available and (b) mirrors the specificity of the data collection strategy. The paper then applies this approach to …

On The Intermediate Long Wave Propagation For Internal Waves In The Presence Of Currents, Joseph Cullen, Rossen Ivanov

Articles

A model for the wave motion of an internal wave in the presence of current in the case of intermediate long wave approximation is studied. The lower layer is considerably deeper, with a higher density than the upper layer. The flat surface approximation is assumed. The fluids are incompressible and inviscid. The model equations are obtained from the Hamiltonian formulation of the dynamics in the presence of a depth-varying current. It is shown that an appropriate scaling leads to the integrable Intermediate Long Wave Equation (ILWE). Two limits of the ILWE leading to the integrable Benjamin-Ono and KdV equations are …

Camassa-Holm Cuspons, Solitons And Their Interactions Via The Dressing Method, Rossen Ivanov, Tony Lyons, Nigel Orr

Articles

A dressing method is applied to a matrix Lax pair for the Camassa–Holm equation, thereby allowing for the construction of several global solutions of the system. In particular, solutions of system of soliton and cuspon type are constructed explicitly. The interactions between soliton and cuspon solutions of the system are investigated. The geometric aspects of the Camassa–Holm equation are re-examined in terms of quantities which can be explicitly constructed via the inverse scattering method.

Integrable Negative Flows Of The Heisenberg Ferromagnet Equation Hierarchy, Rossen Ivanov

Articles

We study the negative flows of the hierarchy of the integrable Heisenberg ferromagnet model and their soliton solutions. The first negative flow is related to the so-called short pulse equation. We provide a framework which generates Lax pairs for the other members of the hierarchy. The application of the dressing method is illustrated with the derivation of the one-soliton solution.

Modeling Gene Expression With Differential Equations, Madison Kuduk

Capstone Showcase

Gene expression is the process by which the information stored in DNA is convertedinto a functional gene product, such as protein. The two main functions that makeup the process of gene expression are transcription and translation. Transcriptionand translation are controlled by the number of mRNA and protein in the cell. Geneexpression can be represented as a system of first order differential equations for the rateof change of mRNA and proteins. These equations involve transcription, translation,degradation and feedback loops. In this paper, I investigate a system of first orderdifferential equations to model gene expression proposed by Hunt, Laplace, Miller andPham in …

Climate Change Models, Lauren Fie

Impact Of Vaccine Availability On The Number Of Children Vaccinated And Under-Five Mortality In Tanzania, Katelyn Batliner

MPA/MPP/MPFM Capstone Projects

Stockouts have previously been reported to interrupt immunization services in low-and-middle income countries. However, there has been little research to understand the direct impact of stockouts on the number of children immunized and no research to understand the impact on under-five mortality. Using panel data from Tanzania’s Vaccine Information Management System training program, a regression model with fixed and random effects is used to analyze the effect of stockouts on the number of children immunized. The Lives Saved Tool® is used to estimate the effect of stockouts on under-five mortality. The results suggest that stockouts have a statistically significant impact …

Capstone Showcase

Neural ordinary differential equations (ODEs) have recently emerged as a novel ap- proach to deep learning, leveraging the knowledge of two previously separate domains, neural networks and differential equations. In this paper, we first examine the back- ground and lay the foundation for traditional artificial neural networks. We then present neural ODEs from a rigorous mathematical perspective, and explore their advantages and trade-offs compared to traditional neural nets.

The Integration Of Lidar And Legacy Datasets Provides Improved Explanations For The Spatial Patterning Of Shell Rings In The American Southeast, Dylan S. Davis, Robert Dinapoli, Matthew Sanger, Carl Lipo

Anthropology Datasets

Archaeologists have struggled to combine remotely sensed datasets with preexisting information for landscape-level analyses. In the American Southeast, for example, analyses of lidar data using automated feature extraction algorithms have led to the identification of over 40 potential new pre-European-contact Native American shell ring deposits in Beaufort County, South Carolina. Such datasets are vital for understanding settlement distributions, yet a comprehensive assessment requires remotely sensed and previously surveyed archaeological data. Here, we use legacy data and airborne lidar-derived information to conduct a series of point pattern analyses using spatial models that we designed to assess the factors that best explain …

Searching For The Golden Rule: A Case Study Of Two White Novice Teachers' Beliefs And Experiences Of Respect In Urban Schools, Shannon Audley

Education and Child Study: Faculty Publications

Student respect toward teachers is traditionally considered in terms of behavior or authority. Yet, because of cultural differences and historic oppression of marginalized students in schools, not all students express respect in ways in which teachers are familiar. Because of structural inequalities and individual differences, standard behavioral definitions of respect are insufficient to address how students and teachers actually experience respect in the classroom. Using a comparative case study design, this study examined two female White novice teachers’ beliefs and experiences of student respect within a novel relational respect framework. Results identified that teachers’ respect beliefs were based on notions …

Simulating A Computational Biological Model, Rather Than Reading, Elicits Changes In Brain Activity During Biological Reasoning, Caron Clark, Tomáš Helikar, Joseph T. Dauer

Department of Educational Psychology: Faculty Publications

The creation and analysis of models is integral to all scientific disciplines, and modeling is considered a core competency in undergraduate biology education. There remains a gap in understanding how modeling activities may support changes in students’ neural representations. The aim of this study was to evaluate the effects of simulating a model on undergraduates’ behavioral accuracy and neural response patterns when reasoning about biological systems. During brief tutorials, students (n = 30) either simulated a computer model or read expert analysis of a gene regulatory system. Subsequently, students underwent functional magnetic resonance imaging while responding to system-specific questions and …

Foster Rhodes Jackson And The Visual Conquest Of The West, Eve Kaufman

Scripps Senior Theses

Colonizers settled the Los Angeles and the Southern California region in part by using Modernism’s visual rhetoric and propagandic implications during the time of suburban sprawl. Suburban sprawl refers to the mass single family home development which took place from the 1920^[1]s until now but peaked from the 1970s to the 1990s. Los Angeles sprawl grew particularly in the 1950^[2]s as soldiers returned from WWII. It was a way for middle class white families to accrue generational wealth and follow through on the American Dream^[3].

The primary result however disenfranchised already marginalized groups. This …
