Development Of Comprehensive Theoretical Morphospaces For Canine Cranial Morphology, Alexa Ortega, Nicholas Hebdon, Lindsay Waldrop

Student Scholar Symposium Abstracts and Posters

Throughout the evolution of the family Canidae, there is a continuous belief that canines have an exceptional olfactory system which allows them to have a heightened sense of smell. Because of this olfactory sophistication, canines have become prevalent as detection animals in the military, homeland security, law enforcement, forensics, and civilian applications. However, while the trait is highly regarded, the exact role of nasal morphology is understudied. We aim to investigate the influences of nasal cavity and internal structure morphology in odor detection. However, nasal structure is a sophisticated morphological target and requires innovative solutions to capture the key variables …

Media Influences On Fear Of Immigrants, Mira Eissa Dec 2021

Media Influences On Fear Of Immigrants, Mira Eissa

Student Scholar Symposium Abstracts and Posters

The 2016 election and President Donald Trump’s administration, tapped into U.S. citizens’ polarization regarding the topic of immigration. There was and is a clear negative depiction of immigrants in many different local and national outlets including social media. Using the data collected from Chapman's survey of American fears in 2021, I analyze how fear of immigrants is related to media consumption. Social media and news outlets' coverage of immigrants directly influences the public’s attitudes. Agenda setting, priming, and framing help us understand that news and media construct a perception for people that might not be accurate. Citizens have formed their …

Metaphors Of International Law, Harlan G. Cohen Dec 2021

Metaphors Of International Law, Harlan G. Cohen

Scholarly Works

This chapter explores international law in search of its hidden and not-so-hidden metaphors. In so doing, it discovers a world inhabited by states, where rules are mined or picked when ripe, where trade keeps boats forever afloat on rising tides. But is also unveils a world in which voices are silenced, inequality is ignored, and hands are washed of responsibility.

International law is built on metaphors. Metaphors provide a language to describe and convey the law’s operation, help international lawyers identify legal subjects and categorize situations in doctrinal categories, and provide normative justifications for the law. Exploring their operation at …


Recirculation In Trickling Filters., Ahmed Fadel Dec 2021

Recirculation In Trickling Filters., Ahmed Fadel

Mansoura Engineering Journal

Recirculation is the least understood of factors that affect on the mechanism and performance of the trickling filter. When recirculation is used, this works out in to applying almost the same organic mass to the trickling filter but with the increased hydraulic rate and a lower organic concentration than without recirculation. In this analysis, the organic concentration was divided into low organic concentration where the first order kinetic prevails and high organic concentration where the zero order kinetic predominates. The effect of recirculation on trickling filter performance under the two kinetic conditions were studied theoretically and by manipulating other researchers …

A Digital Fir Filter For Qrs Complex Detection., Fatma Abou-Chadi, M. Elzalabani, Manal Saleh

Mansoura Engineering Journal

A digital filtering algorithm is presented that is suitable for automatic detection of QRS complexes. A bandpass nonrecursive finite impulse response ( NRFIR ) filter is used to suppress lower frequency frequencies of the ECG signal, which are inherently nonstationary, and to model the frequency response of the optimal matched filter. This digital filter is time saving and it provides linear phase characteristics so that the time of QRS occurrences is not affected. Its capability is demonstrated by applying the filtering to simulated and true ECG records. The detection rate very noisy records reaches 100 percent.

Speech Coding In The Sequency Domain., Fayez Soliman Dec 2021

Speech Coding In The Sequency Domain., Fayez Soliman

Mansoura Engineering Journal

Digital transmission of speech presents the opportunity to provide a more secure and bandwidth efficient service with a consistent quality. The feasibility and cost efficiency of future systems depends largely on the availability of low bit rate vocoders. Orthogonal transformations offer a means for reduction of the bit rate necessary for the transmission of speech signals. The ability to reduce the bit rate resides in the fact that the variance of the orthogonal function coefficients is far less than the variance of the speech itself. Discrete Walsh and Haar transforms are examined for their capacity to reduce the bit rate …
