It is tractable to increase the torque for an HCCI engine and one way is to add a turbocharger. Operating in HCCI mode requires accurate control of the combustion phasing, CA50. The higher the engine torque, the narrower the CA50 window becomes where HCCI operation is maintained. As the CA50 varies stochastically between cycles this requires improved CA50 control for turbo HCCI engines. The main f

This paper details and discusses work performed at the woodworking SME Mivelaz Techniques Bois SA within the SMErobotics FP7 project. The aim is to improve non-expert handling of the cell by introduction of cognitive abilities in the robot system. Three areas are considered; intuitive programming, process adaptation and system integration. Proposed cognitive components are described together with

Introduction: It has previously been found that strongly predicted words can be pre-activated in constraining contexts (e.g. DeLong, Urbach & Kutas, 2005). Furthermore, it has been suggested that an anticipated continuation from one syllable to another can be pre-activated before it is present in the input (Roll, Söderström, Mannfolk, Shtyrov, Johansson, van Westen & Horne, 2015). We descr

Braided convolutional codes (BCCs) are a class of spatially coupled turbo-like codes (SC-TCs) with excellent belief propagation (BP) thresholds. In this paper we analyze the performance of BCCs in the finite block-length regime. We derive the average weight enumerator function (WEF) and compute the union bound on the performance for the uncoupled BCC ensemble. Our results suggest that the union bo

In relation to traditional modes of research within academic context, there is a recent interest in research methods where artistic practices set a larger part of the managerial guidelines, i. e. where the artist or artwork is not the subject of investigation, but rather the operative agent for the carrying through of a project and for the dissemination of results. These methods are by necessity t

Smart contracts are programs with data (mutable state); stored on and executed by blockchain platforms. The transactions (or function invocations) dispatched to smart contracts often change their state. In the Ethereum blockchain, nodes (aka miners/validators) can schedule a set of transactions in any order in a block. Multiple transactions in a single block operating on a contract's shared state

Objective: The purpose of this paper is to identify the largest cognitive challenges faced by novices, developing software in teams, using distributed cognition as an observational filter.Paradigm: Design science Epistemology: Pragmatist Methodology: Case studyMethod: Using grounded theory, ethnography and multi method data collection, we conducted an observational study for two months following f

This paper presents a stabilized scheme that solves the wave propagation problem in a general bianisotropic, stratified medium. The method utilizes the concept of propagators, i.e., the wave propagation operators that map the total tangential electric and magnetic fields from one plane in the slab to another. The scheme transforms the propagator approach into a scattering matrix form, where a spec

Understanding the nature and origin of the precursor material to terrestrial planets is key to deciphering the mechanisms and timescales of planet formation1. Nucleosynthetic variability among rocky Solar System bodies can trace the composition of planetary building blocks2–5. Here we report the nucleosynthetic composition of silicon (μ30Si), the most abundant refractory planet-building element, i

The COVID-19 pandemic precipitated numerous changes in daily life, including the cancellation and restriction of sports globally. Because sports participation contributes positively to the development of student-athletes, restricting these activities may have led to long-term mental health changes in this population. Using a repeated cross-sectional study design, we measured rates of depression us

The pursuit of commercialization is at the core of economic activity, and limited commercialization success is generally ascribed to the lower scalability or potential of the venture. Drawing on the anti-profit-taking socio-institutional perspective and innovation resistance theory, commercialization of a value-creating technology could be resisted from the demand side. We use a 3D surgical video

Artificial intelligence (AI)-assisted code generation is everywhere these days. Undoubtedly, AI will help near-future developers substantially by providing code suggestions and automation. In this application, explainability will be a key quality attribute.
