Dynamic Modeling and Experimental Verification of Powered Parafoil With Two Suspending Points

open access: yesIEEE Access, 2020
This paper presents the dynamic modeling process of a powered parafoil (PPF). The PPF is composed of parafoil and payload equipped with a propeller. The payload is suspended to the parafoil via two suspending points, therefore the motion of the payload ...

Surprising simplicity in the modeling of dynamic granular intrusion

open access: yes, 2021
Granular intrusions, such as dynamic impact or wheel locomotion, are complex multiphase phenomena where the grains exhibit solid-like and fluid-like characteristics together with an ejected gas-like phase.

Modeling Cultural Dynamics

open access: yesCoRR, 2008
EVOC (for EVOlution of Culture) is a computer model of culture that enables us to investigate how various factors such as barriers to cultural diffusion, the presence and choice of leaders, or changes in the ratio of innovation to imitation affect the diversity and effectiveness of ideas. It consists of neural network based agents that invent ideas for

A Dynamic Model of Repositioning [PDF]

open access: yesMarketing Science, 2018
Consumer preferences change through time and firms must adjust their product positioning for their products to continue to be appealing to consumers. These changes in product positioning require fixed investments such that firms reposition only occasionally. I construct a model that can include predictable and unpredictable consumer preference changes,

‘They Need to Hear You Say It’: Healthcare Professionals’ Perspectives on Barriers and Enablers to End‐of‐Life Discussions With Adolescents and Young Adults With Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT End‐of‐life conversations with adolescents and young adults (AYAs) with cancer rarely occur without the guidance of healthcare professionals. As a part of the ‘Difficult Discussions’ study, focused on palliative care and advance care planning discussions with AYAs with cancer, we investigated the factors that healthcare professionals identify ...

Defining Roles in Pediatric Palliative Care: Perspectives From Oncology and Palliative Care Teams

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Early integration of pediatric palliative care (PPC) is associated with improved symptom management, quality of life, and healthcare utilization for children with cancer. Despite this, variation persists in how PPC is understood, operationalized, and integrated within pediatric oncology programs. In particular, ambiguity surrounding
