A Framework To Reveal Clandestine Organ Trafficking In The Dark Web And Beyond, Michael P. Heinl, Bo Yu, Duminda Wijesekera

Journal of Digital Forensics, Security and Law

Due to the scarcity of transplantable organs, patients have to wait on long lists for many years to get a matching kidney. This scarcity has created an illicit market place for wealthy recipients to avoid long waiting times. Brokers arrange such organ transplants and collect most of the payment that is sometimes channeled to fund other illicit activities. In order to collect and disburse payments, they often resort to money laundering-like schemes of money transfers. As the low-cost Internet arrives in some of the affected countries, social media and the dark web are used to illegally trade human organs. This ...

Astria Ontology: Open, Standards-Based, Data-Aggregated Representation Of Space Objects, Jennie Wolfgang, Kathleen Krysher, Michael Slovenski, Unmil P. Karadkar, Shiva Iyer, Moriba K. Jah

Space Traffic Management Conference

The necessity for standards-based ontologies for long-term sustainability of space operations and safety of increasing space flights has been well-established [6, 7]. Current ontologies, such as DARPA’s OrbitOutlook [5], are not publicly available, complicating efforts for their broad adoption. Most sensor data is siloed in proprietary databases [2] and provided only to authorized users, further complicating efforts to create a holistic view of resident space objects (RSOs) in order to enhance space situational awareness (SSA).

The ASTRIA project is developing an open data model with the goal of aggregating data about RSOs, parts, space weather, and governing policies in ...

Discrete Information Object Analysis Of Primary Flight Display Clutter, Kenneth Ward Aug 2018

Discrete Information Object Analysis Of Primary Flight Display Clutter, Kenneth Ward

National Training Aircraft Symposium (NTAS)

Modern aircraft utilize digital display screens to provide critical flight and system status information to pilots. As computing power has increased, the number of data sources and information presented has also increased, with the goal of increasing situational awareness. However, the display can become cluttered with extraneous or irrelevant information, to the detriment of pilot cognitive workload. Pilot perceptions of clutter vary with flight experience, introducing unique considerations in the flight training environment, given the experience difference between instructors and students.
