Additive Manufacturing of Patient‐Specific Intracranial Aneurysm Cell Culture Models

open access: yesAdvanced Materials Technologies, EarlyView.
Patient‐specific intracranial aneurysm models were fabricated using chocolate moulding, 3D printed water‐soluble cores, and direct resin 3D printing. Moulding PDMS around sacrificial cores made of chocolate or 3D printed water‐soluble resin yielded accurate, expandable, and endothelializable models that outperformed resin‐based approaches.

THE CONSISTENCY CONDITIONS FOR DENSITY LIMITS OF HYPOPLASTIC CONSTITUTIVE LAW

open access: yesTASK Quarterly, 2000
The so called phase diagram of grain skeletons illustrates the range of possible void ratios between the pressure dependent bounds ei and et. It can be shown that in the framework of the actual hypoplastic model these bounds can be surpassed by ...

An innovative method to assess specific charge, drilling and blasting costs considering critical factors of rock mass properties, fragment size and blasthole parameters

open access: yesResults in Engineering
The specific charge has been given as a function of the blastability index (BI) only in previous research, whereas fragment size is one of the attractive blasting results. The impacts of combination of the important factors such as fragment size, in-situ

Effect of grain scale geometric heterogeneity on tensile stress generation in rock loaded in compression

open access: yes, 2012
Brittle failure of rock is dominated by tensile mechanisms even in an overall compressive stress field. Heterogeneities play a key role in the development of the localized tensile conditions.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

open access: yesAdvanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Snow avalanche hazard of the Krkonoše National Park, Czech Republic

open access: yesJournal of Maps, 2017
This paper presents a snow avalanche hazard map of the most avalanche-prone mountain range in the Czech Republic, the Krkonoše Mountains. The map was prepared using historical records of 1132 avalanches which occurred over the last 54 years and state-of ...
