Functional clustering of mouse ultrasonic vocalization data. [PDF]

open access: yesPLoS ONE, 2018
Mouse ultrasonic vocalizations (USVs) are studied in many fields of science. However, various noise and varied USV patterns in observed signals make complete automatic analysis difficult.

Development and Performance Measurement of an Affordable Unmanned Surface Vehicle (USV)

open access: yesAutomation, 2022
Indonesia is a maritime country that has vast coastal resources and biodiversity. To support the Indonesian maritime program, a topography mapping tool is needed. The ideal topography mapping tool is the Unmanned Surface Vehicle (USV).

Multidisciplinary design of a micro-USV for re-entry operations [PDF]

open access: yes, 2010
Unmanned Space Vehicles (USV) are seen as a test-bed for enabling technologies and as a carrier to deliver and return experiments to and from low-Earth orbit.

Synchronized Motion-Based UAV–USV Cooperative Autonomous Landing

open access: yesJournal of Marine Science and Engineering, 2022
A synchronous motion-based control strategy for unmanned aerial vehicle (UAV) landing on an unmanned surface vehicle (USV) is proposed to address the problem of low accuracy or even failure of UAV landing on the surface of a USV under wave action ...

The yielding dynamics of a colloidal gel [PDF]

open access: yes, 2009
Attractive colloidal gels display a solid-to-fluid transition as shear stresses above the yield stress are applied. This shear-induced transition is involved in virtually any application of colloidal gels.

A hybrid air-sea cooperative approach combined with a swarm trajectory planning method

open access: yesPaladyn, 2020
This work addresses the issue of ocean monitoring and clean-up of polluted zones, as well as the notion of trajectory planning and fault tolerance for semi-autonomous unmanned vehicles.

Finitely generated ideal languages and synchronizing automata [PDF]

open access: yes, 2013
We study representations of ideal languages by means of strongly connected synchronizing automata. For every finitely generated ideal language L we construct such an automaton with at most 2^n states, where n is the maximal length of words in L.

Closed string radiation from moving D-branes [PDF]

open access: yes, 1997
We compute the amplitude for the radiation of massless NS-NS closed string states from the interaction of two moving D-branes. We consider particle-like D-branes with reference to 4-dimensional spacetime, in toroidal and orbifold compactifications, and ...

Possible Effects of Noncommutative Geometry on Weak CP Violation and Unitarity Triangles [PDF]

open access: yes, 2002
Possible effects of noncommutative geometry on weak CP violation and unitarity triangles are discussed by taking account of a simple version of the momentum-dependent quark mixing matrix in the noncommutative standard model.
