Infill Design Reinforcement of 3D Printed Parts Using Refinement Technique Adapted to Continuous Extrusion

open access: yesJournal of Manufacturing and Materials Processing, 2021
In this paper, we introduce an advanced numerical tool aimed to optimise the infill design of 3D printed parts by reducing printing time. In 3D printing, the term infill refers to the internal structure of a part.

Relational Concurrent Refinement Part III: Traces, partial relations and automata [PDF]

open access: yes, 2014
Data refinement in a state-based language such as Z is defined using a relational model in terms of the behaviour of abstract programs. Downward and upward simulation conditions form a sound and jointly complete methodology to verify relational data ...

Impact of Refinements to Handling and Restraint Methods in Mice

open access: yesAnimals, 2022
There is increasing evidence that, compared to non-aversive handling methods (i.e., tunnel and cupping), tail handling has a negative impact on mouse welfare.

Refinement of Intentions [PDF]

open access: yes, 2016
According to Bratman, future-directed intentions are high-level plans. We view such plans as high-level actions that can typically not be executed directly: they have to be progressively refined until executable basic actions are obtained. Higher- and lower-level actions are linked by the means-end relation, alias instrumentality relation.

Anesthesia and analgesia for experimental craniotomy in mice and rats: a systematic scoping review comparing the years 2009 and 2019

open access: yesFrontiers in Neuroscience, 2023
Experimental craniotomies are a common surgical procedure in neuroscience. Because inadequate analgesia appears to be a problem in animal-based research, we conducted this review and collected information on management of craniotomy-associated pain in ...

Grain refinement efficiency of a new oxide-containing master alloy for aluminium casting alloys [PDF]

open access: yes, 2014
In this study, grain refinement efficiency of a new oxide master alloy based on MgAl2O4 was demonstrated on an A357 alloy. The grain size of the reference alloy was reduced by 50-60% with the addition of the master alloy and introduction of ultrasonic ...

Chemical vapor deposition of poly-p-xylylene in narrow tubes

open access: yesAIP Advances, 2017
Depositing a film via chemical vapor deposition results in superior conformity compared with other deposition techniques, primarily due to the unique chemical interactions between the surface and the reactive compounds.

Abstraction Refinement Guided by a Learnt Probabilistic Model [PDF]

open access: yes, 2015
The core challenge in designing an effective static program analysis is to find a good program abstraction -- one that retains only details relevant to a given query. In this paper, we present a new approach for automatically finding such an abstraction.

Big Data Refinement [PDF]

open access: yes, 2016
"Big data" has become a major area of research and associated funding, as well as a focus of utopian thinking. In the still growing research community, one of the favourite optimistic analogies for data processing is that of the oil refinery, extracting ...

A Case Study in Partial Specification: Consistency and Refinement for Object-Z [PDF]

open access: yes, 2000
The 'viewpoint' approach, in which a system is described by several partial specifications, has been proposed as a way of making complex computing systems more understandable.
