Improving M-Learners' Performance Through Deep Learning Techniques By Leveraging Features Weights, Muhammad Adnan, Asad Habib, Jawad Ashraf, Babar Shah, Gohar Ali

All Works

© 2013 IEEE. Mobile learning (M-learning) has gained tremendous attention in the educational environment in the past decade. For effective M-learning, it is important to create an efficient M-learning model that can identify the exact requirements of mobile learners (M-learners). M-learning model is composed of features that are generated during M-learners' interaction with mobile devices. For an adaptive M-learning model, not only learning features are required, but it is also important to determine how they differ for various M-learners, their weights, and interrelationship. This study proposes a robust and adaptive M-learning model that is based on machine learning and deep …

Insights Into Acinetobacter Baumannii: A Review Of Microbiological, Virulence, And Resistance Traits In A Threatening Nosocomial Pathogen, Carole Ayoub Moubareck, Dalal Hammoudi Halat

All Works

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. Being a multidrug-resistant and an invasive pathogen, Acinetobacter baumannii is one of the major causes of nosocomial infections in the current healthcare system. It has been recognized as an agent of pneumonia, septicemia, meningitis, urinary tract and wound infections, and is associated with high mortality. Pathogenesis in A. baumannii infections is an outcome of multiple virulence factors, including porins, capsules, and cell wall lipopolysaccharide, enzymes, biofilm production, motility, and iron-acquisition systems, among others. Such virulence factors help the organism to resist stressful environmental conditions and enable development of severe infections. Parallel …

Illusory Conflicts: Post-Employment Clearance Procedures And The Ftc’S Technological Expertise, Lindsey Barrett, Laura M. Moy, Paul Ohm, Ashkan Soltani

Georgetown Law Faculty Publications and Other Works

The federal government restricts what former employees can work on after they leave the government, and for good reason. These post-employment conflict restrictions attempt to address the “revolving door” problem, where employees take information learned from their position in government to unfairly advantage industry. But an unintended consequence of overbroad conflict rules is that they impede well-meaning, former federal employees from providing their knowledge and general expertise to other enforcement agencies with similar missions, such as those at the state level. This is playing out right now with FTC technologists, at a time when the agency—and, indeed, consumer protection agencies …

Negotiating The Boundaries Of The Medical Model: Experiences Of People With Epilepsy, Stephanie Kılınç, Carol Campbell, Alison Guy, Anna Van Wersch

All Works

© 2019 Elsevier Inc. People with epilepsy (PWE) continually report dissatisfaction with the support they receive, particularly in regard to their psychological wellbeing. With its focus on optimal seizure control, epilepsy treatment is entrenched in the medical model of illness, despite growing evidence of the broader psychosocial impact of the condition. This study aimed to explore how PWE experience healthcare in the context of their lives. Semistructured interviews were conducted with thirty-nine adults with epilepsy from across the UK. An adapted version of interpretative phenomenological analysis (IPA) was conducted, and three superordinate themes were identified. Firstly, “negotiating the space between …

On The Validation Of Web X.509 Certificates By Tls Interception Products, Ahmad Samer Wazan, Romain Laborde, David Chadwick, Remi Venant, Abdelmalek Benzekri, Eddie Billoir, Omar Alfandi

All Works

The Transport Layer Security (TLS) protocol aims to provide confidentiality and integrity of data. It is based on X.509 Certificates. Our previous research showed that popular Web Browsers exhibit non-standardized behaviour with respect to the certificate validation process [1]. This paper extends that work by examining their handling of OCSP Stapling. We also examine several popular HTTPS interception products, including proxies and anti-virus tools, regarding their certificate validation processes. We analyse and compare their behaviour to that described in the relative standards. Finally, we propose a system that allows the automation of certificate validation tests.

The Role Of State And Federal Law In Energy Condemnations, Stewart E. Sterk

Articles

When an energy provider condemns fee interests or easements to permit construction of transmission lines, what roles do state and federal law play in determining the "just compensation" available to affected landowners? That question has arisen in a number of different factual contexts. Usually, condemnors seek to avoid state law rules that provide for compensation beyond what they believe represents the market value of the property they seek to acquire. For instance, condemnors may seek an offset for benefits the condemnation generates for neighboring land owned by the condemnee. Condemnors may also seek to avoid state rules that entitle condemnees …

Selective Subtraction For Handheld Cameras, Adeel A. Bhutta, Imran Nazir Junejo, Hassan Foroosh

All Works

© 2013 IEEE. Background subtraction techniques model the background of the scene using the stationarity property and classify the scene into two classes namely foreground and background. In doing so, most moving objects become foreground indiscriminately, except in dynamic scenes (such as those with some waving tree leaves, water ripples, or a water fountain), which are typically 'learned' as part of the background using a large training set of video data. We introduce a novel concept of background as the objects other than the foreground, which may include moving objects in the scene that cannot be learned from a training …

© 2020 Sujeet More et al. Magnetic resonance imaging (MRI) is precise and efficient for interpreting the soft and hard tissues. Moreover, for the detailed diagnosis of varied diseases such as knee rheumatoid arthritis (RA), segmentation of the knee magnetic resonance image is a challenging and complex task that has been explored broadly. However, the accuracy and reproducibility of segmentation approaches may require prior extraction of tissues from MR images. The advances in computational methods for segmentation are reliant on several parameters such as the complexity of the tissue, quality, and acquisition process involved. This review paper focuses and briefly …

Giving Back A Fraudulent Transfer: A Defense To Liability?, David G. Carlson

Articles

In Whitlock v. Lowe (In re Deberry) (5th Cir. 2019), the Fifth Circuit court of appeals found it obvious that if a transferee gives back fraudulently transferred funds (which the debtor then dissipates), the transferee has a complete defense to liability to the transferor’s bankruptcy trustee. This puts the Fifth Circuit at odds with the Sixth and Seventh Circuits, where the prepetition give-back counted as no defense. This article concludes that a more nuanced position should mediate between these extremes, based on an “innocent donee” defense retrieved from Nineteenth Century precedent. The article emphasizes that if bad faith transferees for …

Uvis: A Formula-Based End-User Tool For Data Visualization, Mohammad Amin Amin Kuhail, Soren Lauesen

All Works

© 2013 IEEE. Existing approaches to data visualization are one of these two: accessible to end-user developers but limited in customizability, or inaccessible and expressive. For instance, commercial charting tools are easy to use, but support only predefined visualizations, while programmatic visualization tools support custom visualizations, but require advanced programming skills. We show that it is possible to combine the learnability of charting tools and the expressiveness of visualization tools. Uvis is an interactive visualization and user interface design tool that targets end-user developers with skills comparable to spreadsheet formulas. With Uvis, designers drag and drop visual objects, set visual …
