Motion and Morphology Planning for Autonomous Manipulation in Clutter With a Shape‐Shifting, Variable‐Stiffness Robot

open access: yesAdvanced Intelligent Systems, EarlyView.
A hybrid mobile robot with a modular Variable‐Stiffness Bridge transitions between a rigid locomotion platform and a flexible, shape‐conforming body. By enclosing objects within its deformable structure rather than relying on dedicated end effectors, the robot achieves orientation‐regulated planar transport, with conformal contact quality shown to ...

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Spremljanje in preprečevanje nevarnosti tvorjenja usedlin in lakastih oblog

open access: yesVentil
Varnish deposits represent one of the key, yet often overlooked, causes of reduced reliability in modern hydraulic and lubrication systems. Their impact does not manifest as sudden failures, but rather as a gradual degradation of performance, which can ...

SHIP PREDICTIVE CONTROL SYSTEM DESIGN BASED ON THE VESSEL DIGITAL TWIN [PDF]

open access: yesProceedings on Engineering Sciences
Model Predictive Control (MPC) is defined as a model-based approach, thus necessitating the development of an internal predictive model, that is both reliable and realistic.

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

open access: yesThe Anatomical Record, EarlyView.
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

A model predictive control strategy for wind turbine frequency support considering optimal frequency trajectory

open access: yesZhejiang dianli
Existing frequency support control strategies for wind turbines suffer from response delays, may trigger secondary frequency dips, and often involve coarse energy management.

Configuration-Constrained Tube MPC

open access: yesAutomatica
This paper is about robust Model Predictive Control (MPC) for linear systems with additive and multiplicative uncertainty. A novel class of configuration-constrained polytopic robust forward invariant tubes is introduced, which admit a joint parameterization of their facets and vertices.

Exploring the cranial morphology and possible convergences of Triassic non‐crocodylomorph pseudosuchians (Archosauria: Pseudosuchia) with other sauropsids through linear morphometrics

open access: yesThe Anatomical Record, EarlyView.
Abstract Triassic pseudosuchians had highly diversified cranial morphologies. These archosaurs occupied diverse ecological roles, ranging from terrestrial predators and herbivores to semiaquatic ambush predators and possible waders. Here, we apply linear cranial morphometrics to assess possible convergences with other sauropsids from the clades ...

Control of Bioethanol Fermentation Process: NARX-Based MPC (NARX-MPC) versus Linear-Based MPC (LMPC)

open access: yesChemical Engineering Transactions, 2015
Driven by the perspective of fossil fuels depletion, the concerns about energy security and global warming, the promotion of biofuels as energy for transportation in the world has become a popular trending. Bioethanol is one of a potential biofuel with a high octane number and has replaced lead as an octane enhancer in petrol.

Pharmacogenomic profiling of the efficacy of gemcitabine monotherapy in metastatic pancreatic cancer: Subgroup analysis of the GENESECT study

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aim In the GENESECT study, no significant gemcitabine (GEM) metabolism‐related germline genetic polymorphisms (GPs) were identified because approximately 70% of patients received combination therapy with nab‐paclitaxel, which has metabolic pathways different from GEM.
