Joint Carrier Frequency And Phase Offset Estimation Algorithm For Cpm-Dsssbased Secure Point-To-Point Communication, Saima Shehzadi, Farzana Kulsoom, Muhammad Zeeshan, Qasim Umar Khan, Shahzad Amin Sheikh

Turkish Journal of Electrical Engineering and Computer Sciences

A point-to-point (P2P) communication system based on the CPM-DSSS scheme ensures reliability, security, and antijamming capabilities. However, for reliable detection of data carrier synchronization of CPM-DSSS based system is one of the requirements. This paper presents a joint algorithm for carrier frequency offset (CFO) and carrier phase offset (CPO) estimation for CPM-DSSS based P2P system. The results indicate that the proposed CFO estimator is unbiased and can accurately estimate a wide range of offsets. Moreover, the proposed algorithm is compared with another research work. The results show that the proposed CFO and CPO estimation algorithm outperforms its counterpart with a …

A Hybrid Numerical Model For Long-Range Electromagnetic Wave Propagation, Gül Yesa Altun, Özlem Özgün

Turkish Journal of Electrical Engineering and Computer Sciences

A hybrid numerical model is presented for solving long range electromagnetic wave propagation problems involving objects on or above the ground surface by hybridizing the two-way split-step parabolic equation (2W-SSPE) method with the method of moments (MoM). The advantages of the proposed model are twofold: (i) It reduces the staircasing error in irregular terrain modeling, which usually occurs when the standard SSPE method is used alone. This is achieved by employing the MoM to more accurately obtain the scattered fields from slanted/curved surfaces. (ii) It enables the SSPE method to handle the problems involving objects above the Earth's surface, which …

Comparison Of Metaheuristic Optimization Algorithms With A New Modifieddeb Feasibility Constraint Handling Technique, Murat Erhan Çi̇men, Zeynep Gari̇p, Ali̇ Fuat Boz

Turkish Journal of Electrical Engineering and Computer Sciences

In this study, the modification of the Deb feasibility method is considered to solve the constrained optimization problems. In the developed modified Deb feasibility constraint method, the third rule in its procedure was revised in order to increase the performance of the Deb feasibility constraint handling method. The innovation in the method is based on generating a new individual by using both possible solutions that violate the constraints in the method used for solving the problem. In detail, discussions were given about the application and usefulness of six constrained handling techniques. Furthermore, genetic algorithm, particle swarm optimization, Harris hawks optimization, …

Medical Image Fusion With Convolutional Neural Network In Multiscaletransform Domain, Asan Abas, Hasan Erdi̇nç Koçer, Nurdan Baykan

Turkish Journal of Electrical Engineering and Computer Sciences

Multimodal medical image fusion approaches have been commonly used to diagnose diseases and involve merging multiple images of different modes to achieve superior image quality and to reduce uncertainty and redundancy in order to increase the clinical applicability. In this paper, we proposed a new medical image fusion algorithm based on a convolutional neural network (CNN) to obtain a weight map for multiscale transform (curvelet/ non-subsampled shearlet transform) domains that enhance the textual and edge property. The aim of the method is achieving the best visualization and highest details in a single fused image without losing spectral and anatomical details. …

Detection Of Amyotrophic Lateral Sclerosis Disease By Variational Modedecomposition And Convolution Neural Network Methods From Event-Relatedpotential Signals, Fatma Lati̇foğlu, Firat Orhan Bulucu, Rami̇s İleri̇

Turkish Journal of Electrical Engineering and Computer Sciences

Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease, is a neurological disease that occurs as a result of damage to the nerves in the brain and restriction of muscle movements. Electroencephalography (EEG) is the most common method used in brain imaging to study neurological disorders. Diagnosis of neurological disorders such as ALS, Parkinson's, attention deficit hyperactivity disorder is important in biomedical studies. In recent years, deep learning (DL) models have been started to be applied in the literature for the diagnosis of these diseases. In this study, event-related potentials (ERPs) were obtained from EEG signals obtained as a …

The Right To Development, Integral Human Development, And Integral Ecology In The Amazon, Diane A. Desierto, Ilaria Schnyder Von Wartensee

Journal Articles

From the Article

This article discusses the reorientation of environmental protection in Amazonia away from the paradigm of individual and collective natural resource management of regional or global commons, to the more radical thesis of Integral Ecology as the vindication of human dignity, environmental stewardship and collective responsibility - a concept deeply related to the Church's own pioneering of Integral Human Development as the 'authentic development development of every person and of the whole person'. Under the concept of integral Ecology, we argue that this expressive elaboration of the Catholic Church's core social teaching of Integral Human Development ultimately hearkens …

Why We Need Better Corporate Governance Data, Jens Frankenreiter, Cathy Hwang, Yaron Nili, Eric L. Talley

Scholarship@WashULaw

Three decades of finance, economics, and legal studies in corporate governance have been built substantially on data sets with nearly unknown provenance. A new paper sets to correct this fatal flaw of contemporary corporate governance research by debuting a brand new resource—the Cleaning Corporate Governance database.

The Lost Promise Of Progressive Formalism, Andrea Scoseria Katz

Scholarship@WashULaw

Today, any number of troubling government pathologies—a lawless presidency, a bloated and unaccountable administrative state, the growth of an activist bench—are associated with the emergence of a judicial philosophy that disregards the “plain meaning” of the Constitution for a loose, unprincipled “living constitutionalism.” Many trace its origins to the Progressive Era
(1890–1920), a time when Americans turned en masse to government as the solution to emerging problems of economic modernity—financial panics, industrial concentration, worsening workplace conditions, and skyrocketing unemployment and inequality—and, the argument goes, concocted a flexible, new constitutional philosophy to allow the federal government to take on vast, new …

Adapting To Slow-Moving Crises: The Personal Protection Equipment Supply Chain In The Time Of Covid19, Jennifer Shullih, Stephen Lemay

AMTP Proceedings 2021

In this paper, we look at the supply chain for PPE during the COVID-19 pandemic of 2020. We look at the way the supply chain has responded to the pandemic, the coordination of the supply chain relative to the needs of primary users, and the consequences of its use. We find that the supply chain has continued to function more as a commercial supply chain than as an emergency supply chain largely because of a lack of centralized coordination. We include an analysis of existing concepts as they apply to this supply chain, but also incorporate preliminary results from a …

Monitoring Agns With H-Beta Asymmetry: Markarian 841, Samuel J. Schonsberg

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Quasars are among the most luminous objects in the Universe, and the mechanism behind their luminosity was shrouded in mystery decades after their discovery. Since then, we have found that these objects are active galactic nuclei (AGN), which are powered by actively-feeding super massive black holes at the center of a galaxy. But we still know fairly little about the structure and motion of the material surrounding active super massive black holes, and most of these objects are not resolvable by conventional observations. We use a technique called reverberation mapping, which is traditionally used only as a mass determination …

Between April 29, 2018 to November 19, 2019, water samples were collected upstream and downstream of a floating garden installed along the Chicago River. At each location, samples were collected at the surface and at 0.3 m below the surface. In-situ measurements of Dissolved Oxygen, Specific Conductance, and Temperature were recorded with a YSI 85. Anion samples were analyzed using a Ion Chromatograph for fluoride (F^-), chloride (Cl^-), nitrate as nitrogen (NO₃-N), phosphate (PO₄^-3), and sulfate (SO₄^-2). The available dataset provides the recorded field parameters and the analyzed …

The Effectiveness Of An Artificial Floating Wetland To Remove Nutrients In An Urban Stream: A Pilot-Study In The Chicago River, Chicago, Il Usa, Eric W. Peterson, Phil Nicodemus, Emmett Spooner, Abigail Heath

Faculty Publications - Geography, Geology, and the Environment

Ever expanding urbanized landscapes are increasingly impacting streams that run through them. Among other stressors, urban streams often are host to elevated concentrations of nutrients, salts, and heavy metals. The pollutants, coupled with high temperatures, are drivers of ecosystem degradation in urban streams. The installation of artificial floating wetlands (AFWs) has been successful in mitigating the effects of urbanization in lakes and wastewater treatment ponds, but rarely have they been tested in streams. This pilot-study examined the ability of an AFW to improve water quality in an urban stream. The small, 90 m2 AFW was installed to improve the aquatic …

The Data Science Corps Wrangle-Analyze- Visualize Program: Building Data Acumen For Undergraduate Students, Nicholas J. Horton, Benjamin Baumer, Andrew Zieffler, Valerie Barr

Statistical and Data Sciences: Faculty Publications

We congratulate Kolaczyk, Wright, and Yajima on their innovative statistics practicum that places “practice” at the center of data science education (Kolaczyk et al., 2021, this issue). Their year-long practicum course focuses on the data science life cycle with engagement with external partners and university consulting projects. We agree that training postgraduates in practice needs to be foregrounded in the curriculum in order for students to develop necessary depth in data science practice.

In addition to low molecular weight aryl-substituted phosphines, we also are able to prepare functionalized polystyrene products.

Experimental And Numerical Investigation Of Instabilities In A Two-Mirror Fabry-Perot Resonator, Matthew J. Urfer

Graduate Research Theses & Dissertations

Fabry-Perot cavities have a variety of applications in science and industry. Maintaining the stability of a Fabry-Perot cavity is paramount. A Fabry-Perot cavity requires such precision that, if the injected laser pulse is slightly misaligned or the eigenmodes of the cavity are slightly mismatched, the cavity will destabilize from the fundamental mode and begin to exhibit high order modal structure. Depending on their nature, small misalignments will couple to the first order Gaussian modes. This paper discusses the effects of these small misalignments, observed mode structures, as well as computational results from simulations of the optical system.

It's More Than What You Know: Conceptual Understanding And Spatial Skill Impact Student Sequence Stratigraphic Interpretation Skill, Bailey Zo Kreager

Graduate Research Theses & Dissertations

Sequence stratigraphic interpretation and 3-D spatial and spatiotemporal skills are considered important for the petroleum industry. Despite the importance of sequence stratigraphic interpretations for student careers, students struggle to understand basic concepts such as eustasy, relative sea-level and base-level. However, little is known about the relationship between spatial skill and sequence stratigraphy or the impact of instruction on sequence stratigraphic diagrams. This study begins to fill this gap by testing 1) whether spatial skills predict success on a sequence stratigraphic interpretation task, 2) the impact of Wheeler diagram instruction on student sequence stratigraphic interpretation skill, and 3) the impact of …

Applications Of Statistical Experimental Designs To Improve Statistical Inference In Weed Management, Steven B. Kim, Dong Sub Kim, Christina Magana-Ramirez

Mathematics and Statistics Faculty Publications and Presentations

In a balanced design, researchers allocate the same number of units across all treatment groups. It has been believed as a rule of thumb among some researchers in agriculture. Sometimes, an unbalanced design outperforms a balanced design. Given a specific parameter of interest, researchers can design an experiment by unevenly distributing experimental units to increase statistical information about the parameter of interest. An additional way of improving an experiment is an adaptive design (e.g., spending the total sample size in multiple steps). It is helpful to have some knowledge about the parameter of interest to design an experiment. In the …

Political Justificationism: A More Realistic Epistemology Of Political Disagreement, Randolph Jay Carlson

Dissertations

Disagreement is probably the most salient feature of our contemporary political environment. This project aims to examine political disagreements from the perspective of the recent discussions of the epistemology of disagreement more generally. Some, known as conciliationists, argue that when confronted with a disagreement with someone who is equally knowledgeable and well-informed as you are on the issue (known as an "epistemic peer"), one should become substantially less confident in that antecedently held belief. While some have tried to straightforwardly apply the conciliationist approach to political disagreements, I argue that such an approach makes us vulnerable to significant cognitive biases …
