Explainable spatial machine learning for hedonic real estate modeling

open access: yesReal Estate Economics, EarlyView.
Abstract Accurately modeling rents and prices is a key challenge in real estate analysis. Traditional linear models may fail to capture complex non‐linear relationships, and spatial dependencies are often ignored in existing machine‐learning approaches.

Icing simulation: A survey of computer models and experimental facilities [PDF]

open access: yes
A survey of the current methods for simulation of the response of an aircraft or aircraft subsystem to an icing encounter is presented. The topics discussed include a computer code modeling of aircraft icing and performance degradation, an evaluation of ...

Is That a Threat? How Types of Stakeholder and Reputational Threat Matter for Gaining Influence in Regulatory Rulemaking

open access: yesRegulation &Governance, EarlyView.
ABSTRACT This paper assesses what type of comments are most useful to what type of stakeholder in gaining influence during public consultations. Theoretically, the paper approaches stakeholders' consultation comments as reputational threats from key audiences that the agency needs to respond to.

Statistical Study of Aircraft Icing Probabilities at the 700- and 500- Millibar Levels over Ocean Areas in the Northern Hemisphere [PDF]

open access: yes
A statistical study is made of icing data reported from weather reconnaissance aircraft flown by Air Weather Service (USAF). The weather missions studied were flown at fixed flight levels of 500 millibars (18,000 ft) and 700 millibars (10,000 ft) over ...

Examination of Icing Induced Loss of Control and Its Mitigations [PDF]

open access: yes, 2010
Factors external to the aircraft are often a significant causal factor in loss of control (LOC) accidents. In today s aviation world, very few accidents stem from a single cause and typically have a number of causal factors that culminate in a LOC ...

Using unmanned aerial vehicles (drones) to improve access to blood in low‐ and middle‐income countries: Current challenges and opportunities

open access: yesVox Sanguinis, EarlyView.
Abstract Blood transfusion is life‐saving for patients in emergencies, but low‐ and middle‐income countries (LMICs) often face a severe shortage of banked blood. Establishing blood banks in rural areas presents substantial logistical and economic challenges for many LMICs.
