Characterizing Differential Reflectivity Calibration Dependence On Environmental Temperature Using The X-Band Teaching And Research Radar (Xtrra): Looking For A Relationship Between Temperature And Differential Reflectivity Bias, Emma Miller

The Journal of Purdue Undergraduate Research

Calibration scans are important for the maintenance of data and the quality of the information that radars output. In this study we looked for a temperature dependency in a full year’s worth of differential reflectivity (ZDR) calibration scan data collected by the X-band Teaching and Research Radar (XTRRA) located near the Purdue University campus. In a vertically pointing calibration scan, the radar scans the drops from below while rotating. From this angle, the overall shape will be circular, which corresponds to a ZDR value of approximately 0 dB. To process the data for the year 2021, a Python script was …

Machine Learning Of Big Data: A Gaussian Regression Model To Predict The Spatiotemporal Distribution Of Ground Ozone, Jerry Gu

The Journal of Purdue Undergraduate Research

Tracking pollution levels on the ground is important to the environment and public health. One of the pollutants of concern is ozone, which, at high concentrations, can cause respiratory and cardiovascular problems. The National Center for Atmospheric Research (NCAR) has published valuable ozone data obtained from ground-based sensors installed at selected locations. Because it is unfeasible to measure the exact ozone levels everywhere at any time, it would be valuable to predict the temporal-spatial distributions of ozone concentration based on existing data. This would help us better understand the patterns and trends in the data and make better decisions to …

A Computational Profile Of Invasive Lionfish In Belize: A New Insight On A Destructive Species, Joshua E. Balan

The Journal of Purdue Undergraduate Research

Since their discovery in the region in 2009, invasive Indonesian-native lionfish have been taking over the Belize Barrier Reef. As a result, populations of local species have dwindled as they are either eaten or outcompeted by the invaders. This has led to devastating losses ecologically and economically; massive industries in the local nations, such as fisheries and tourism, have suffered greatly. Attempting to combat this, local organizations, from nonprofits to ecotourism companies, have been manually spear-hunting them on scuba dives to cull the population. One such company, Reef Conservation Institute (ReefCI), operating out of Tom Owens Caye outside of Placencia, …

Clouds In The Ancient Lunar Atmosphere: Water Ice Nucleation On Aerosol Simulants, Mariana C. Aguilar

The Journal of Purdue Undergraduate Research

Today’s moon is vastly different from what it was 3 billion years ago. At that time, it was home to a collisional atmosphere formed through massive amounts of volcanism, releasing enough subsurface gas to sustain surface pressures of up to 1 kPa. Observations of our solar system have taught us that all dense atmospheres are host to clouds and aerosols, and we expect the Moon’s to be no different. Knowing when, where, and under what conditions cloud particles form is important for understanding the evolution of the lunar atmosphere, how it reacted to temperature gradients, and how it cycled volatiles. …

The Aim To Decentralize Economic Systems With Blockchains And Crypto, Mary Lacity

Arkansas Law Review

As an information systems (“IS”) professor, I wrote this Article for legal professionals new to blockchains and crypto. This target audience likely is most interested in crypto for its legal implications—depending on whether it functions as currencies, securities, commodities, or properties; however, legal professionals also need to understand crypto’s origin, how transactions work, and how they are governed.

Robots As Pirates, Henry H. Perritt Jr.

Catholic University Law Review

Generative AI has created much excitement over its potential to create new works of authorship in the literary and graphical realms. Its underling machine-learning technology works by analyzing the relations among elements of preexisting material in enormous databases assembled from publicly available and licensed sources. Its algorithms “learn” to predict “what comes next” in different types of expression. A complete system thus can become glib in creating new factual summaries, essays, fictional stories and images.

A number of authors of the raw material used by Generative AI engines claim that the machine learning process infringes their copyrights. Careful evaluation of …

Evaluating The Neotectonic Activities Of The Eastern Makran At The Northern Edge Of The Triple Junction In Southwest Pakistan, Waseem Khan, Ke Zhang, Hao Liang

Turkish Journal of Earth Sciences

A number of five GIS-based indices, such as stream slope (Ss), surface roughness (Sr), asymmetric factor (Af), hypsometry integral (Hi), and stream-length gradient (SL), were summarised to examine the intensity of the index of tectonic activity (IAT) in 43 subbasins of Hingol Basin at the northern edge of the triple junction in southwest Pakistan. In addition, tectonic influences were identified by knickpoints spatial distribution and field surveys. The majority of the indices are consistent and display roughly the same classifications. The uncertain results have a less substantial impact on the obtained results in most of the 43 subbasins. Using these …

Mineralogical And Geochemical Characteristics Of The Upper Cretaceous And Lower Paleocene Parts Of The Germav Formation: Southeastern Türkiye, Sema Teti̇ker

Turkish Journal of Earth Sciences

The mineralogical and chemical characteristics of Upper Cretaceous-Lower Paleocene claystone sediment samples taken from Mardin and Batman, located in southeastern Türkiye, were analyzed in the present study. The clay mineral paragenesis in the Upper Cretaceous units consisted of chlorite-smectite (C-S) and illite, whereas the Lower Paleocene unit consisted of chlorite-vermiculite (CV) and vermiculite minerals. Analyses conducted on clay samples indicated high levels of Al, Mg, Fe, Cr, V, Ni, and Zr. Low levels of alkali and alkaline earth elements (Mg, Na, Ca, K) in the clay-rich sediments suggest relatively high-grade weathering in the source area. The mineralogical compositions, major elemental …

An Experimental Investigation On The Discrete Poisson’S Upward Continuation Of Anomalous Gravity Field Data, Mehmet Si̇mav, Bi̇hter Erol, Muhammet Aki̇f Gülender, Serdar Erol

Turkish Journal of Earth Sciences

The Poisson upward continuation of gravity field functionals, typically given on the Earth’s irregular topography with limited spatial extent, necessitates some proper treatments due to the theoretical requirements. This study reviews the Poisson theory and investigates a more rigorous methodology for the numerical solution of the spherical integral equation by addressing many issues such as spherical-Earth model implementation, far-zone effect, Poisson kernel modification, and suitable ground data reduction scheme. We first explore the far-zone effect and search for an optimal near-zone spherical cap radius above which the truncation error is negligible. We then compare different variants of remove-restore technique with …

According to the moment tensor solutions published by national and international seismology centers, the earthquake occurred at the northeast end of the Karadere segment within the NAFZ and was caused by a right-lateral strike-slip fault in the NW-SE direction. In this study, the differential interferometric synthetic aperture radar (InSAR) method was employed to analyze the deformation. Four Sentinel-1A complex datasets …

Landslide Susceptibility Assessment Of The Asi Watershed, Southern Türkiye, Senem Teki̇n, Adolfo Quesada Román, Tolga Çan

Turkish Journal of Earth Sciences

Landslides constitute recurrent natural hazards worldwide with greater socioeconomic impacts in low-income places. Landslide susceptibility studies are carried out to determine the potential for landslides to occur in a region, to predict possible risks in the future and to integrate this information into sustainable planning and management strategies. Slip-type landslides occur in limited areas of less than 1% of the Asi watershed in Southern Türkiye. Therefore, meaningful estimations cannot be made with classical statistical models. So, using the maximum entropy approach (MaxEnt), a technique for estimating based on a small number of observations, a landslide susceptibility assessment was constructed. The …

Effects Of Advertising Employee Resource Groups (Ergs) On Female Applicants’ Intentions To Pursue Employment Through Perceived Organizational Support, Jamie Crites

Industrial-Organizational Psychology Dissertations

Employee resource groups (ERGs) have existed since the 1960’s to provide additional support for a group of employees within an organization that share a common identity (e.g., gender, race, sexual orientation, veteran status). Gaining in popularity over the past 25 years, they are utilized to drive change and foster diversity management (Welbourne et al., 2017). Organizations have also realized the potential for demonstrating a commitment to diversity to external stakeholders, future applicants, and current employees (Biscoe & Safford, 2010; Friedman & Holtom, 2002). ERGs are unique, thus are difficult to quantify and study empirically. However, given the prevalence of ERGs, …

Veterans Treatment Courts: Broadening Eligibility For Veterans Convicted Of Violent Offenses, Mark Dela Peña

Catholic University Law Review

Veterans treatment courts (VTCs) have been gaining widespread popularity as a tool to divert justice-involved veterans from the criminal justice system. While a step in the right direction, most of these courts categorically exclude violent offenders for eligibility. Many jurisdictions conflate violent offenses with serious offenses, even when many violent offenses lack any physical harm. Additionally, prosecutors wield almost unbridled discretion in determining whether or not someone is charged with an offense considered to be violent, determining VTC eligibility even before a case reaches a sentencing hearing.

This comment argues for admitting veterans convicted of violent offenses into VTCs. This …

Culturally Responsive Teaching And Learning Achievement, Jose Rivera

Education Dissertations

Over the last decades the United States demographics reflect an increase in student diversity and multilanguage learners have changed the landscape of the education system. Educators are having a difficult time connecting, reaching, and teaching many of these diverse and multilingual learners. As a result, culturally and linguistically diverse students are not successful in school and are pushed out of secondary schools at an alarming rate. The United States educational system faces a glaring discrepancy of teacher and student demographics. In America 84% of teachers are White not Hispanic, only 6% of teachers are Latino/Hispanic, 8% are Black and less …
