Embedded multi-spectral image processing for real-time medical application
2016
International audience; The newly introduced Kubelka-Munk Genetic Algorithm (KMGA) is a promising technique for the assessment of skin lesions from multi-spectral images. Using five skin parameter maps such as concentration or epidermis/dermis thickness, this method combines the Kubelka-Munk Light-Tissue interaction model and Genetic Algorithm optimization process to produce a quantitative measure of cutaneous tissue. Up to the present, variant improved KMGA implementations have been successfully realized using the recent parallel computing techniques. However, all these achievements are based on the multi-core CPUs. This results in a quite high cost and low practicability for the hardware …
Balancing Structural and Temporal Constraints in Multitasking Contexts
2016
Recent research has shown that when people multitask, both the subtask structure and the temporal constraints of the component tasks strongly influence people’s task-switching behavior. In this paper, we propose an integrated theoretical account and associated computational model that aims to quantify how people balance structural and temporal constraints in everyday multitasking. We validate the theory using data from an empirical study in which drivers performed a visual-search task while navigating a driving environment. Through examination of illustrative protocols from the model and human drivers as well as the overall fit on the aggregate glance data, we explore the implications of th…
Java-COM integration with JACOB using XML wrappers
2006
Many Windows-based legacy applications can be programmatically accessed using COM interfaces. However, calling COM components from Java is not straightforward. This report compares four open source Java-COM integration packages. A technique for typesafe Java-COM integration is presented. The technique is based on typesafe COM interface wrappers using jcom, java2com and JACOB libraries. Examples with Microsoft Office applications are presented. XML wrapper and code generator can be bundled with future JACOB releases as an alternative to Jacobgen wrapper generator. nonPeerReviewed
Learning to survive amidst nested crises: can the coronavirus pandemic help us change educational practices to prepare for the impending eco-crisis?
2021
The ongoing ecological crisis and the more recent Coronavirus crisis challenge the grand narrative of Enlightenment that human beings are ‘masters of nature’. For millennia, human social learning has allowed Homo sapiens to outpace most of our competitor creatures and live a comfortable life, but this competitive success has resulted in cataclysmic failure for the ecosystem. However, people’s unique ability to learn gives us hope that we can overcome the nested crises, or learn to live with them. What is required is not more knowledge, but instead, collective learning to change practices, institutionalized in educational processes. Drawing on the theory of practice architectures, this paper…
Fundamental bounds on qubit reset
2020
Qubit reset is a basic prerequisite for operating quantum devices, requiring the export of entropy. The fastest and most accurate way to reset a qubit is obtained by coupling the qubit to an ancilla on demand. Here, we derive fundamental bounds on qubit reset in terms of maximum fidelity and minimum time, assuming control over the qubit and no control over the ancilla. Using the Cartan decomposition of the Lie algebra of qubit plus two-level ancilla, we identify the types of interaction and controls for which the qubit can be purified. For these configurations, we show that a time-optimal protocol consists of purity exchange between qubit and ancilla brought into resonance, where the maximu…
From Solid Spaces To Liquid Spaces: New Ecologies of Musical Practices.
2019
Purpose: In recent years, the interest in creating new educational spaces has increased substantially, aiming to influence the methods of learning of our students and to adopt new educational strategies. This article highlights the importance of the atmosphere when remodeling musical practices. Methodologically, when transforming a space, we do not only have to improve the physical architectures but also the pedagogical ones, as well as keeping the practices consistent with these changes. The MUSICLAB CR-209 'Sound laboratory' have been built in Valencia (Spain). This is a hybrid space designed especially for collaborative projects -teachers, artists, students and researchers- in which soun…
Inside Cover: Hydrogen-Bonded Open-Framework with Pyridyl-Decorated Channels: Straightforward Preparation and Insight into Its Affinity for Acidic Mo…
2017
International audience; A hydrogen-bonded open framework with pores decorated by pyridyl groups was constructed by off-charge-stoichiometry assembly of protonated tetrakis(4-pyridyloxymethyl)methane and [Al(oxalate)(3)](3-), which are the H-bond donor and acceptor of ionic H-bond interactions, respectively. This supramolecular porous architecture (SPA-2) has 1nm-large pores interconnected in 3D with large solvent-accessible void (53%). It demonstrated remarkable affinity for acidic organic molecules in solution, which was investigated by means of various carboxylic acids including larger drug molecules. Competing sorption between acetic acid and its halogenated homologues evidenced good sel…
Articulating the Practice Architectures of Collaborative Research Practice
2016
This chapter explores a collaborative practice of comparative data analysis through the researching activities of four researchers from Australia and Finland. We interrogate the ontological and empirical reality we experienced while engaged in a practice of analysing narrative data on mentoring. In this chapter, we are not reporting on the outcomes of our analysis of mentoring practice; instead we focus on our collaborative engagement, articulating the practice architectures of our research practice. This collaborative research practice was pre-figured by: (1) philosophical traditions instituted through a theory of practice architectures; and (2) normalised practices of researching mentorin…
Miten muuttaa käytäntöjä ihmisen ja luonnon kannalta kestäviksi? : ekososiaalinen sivistys käytäntöarkkitehtuuriteorian valossa
2023
Aikamme suurin haaste ei ole luotettavan tiedon puuttuminen vaan toimintatapojemme muuttaminen. Kasvatus ja koulutus ovat ratkaisevia, jotta käytäntöjämme voisi muuttaa sosiaalisesti ja ekologisesti kestävämmiksi maapallon ekosysteemien ollessa kriisissä. Tässä artikkelissa hahmotellaan käytäntöteoreettista näkökulmaa kestävän elämänmuodon edistämiseksi kasvatuksen ja sivistyksen avulla. Ratkaisuksi ongelmaan on ehdotettu ekososiaalisen sivistyksen lisäämistä. Perinteinen tulkinta sivistyksestä on kuitenkin ongelmallinen sen ollessa kognitiivisesti painottunutta, abstraktia ja ihmiskeskeistä. Ehdotamme sivistyksen tulkintaa, joka painottaa käytäntöjen ontologista ensisijaisuutta. Huomio koh…
Towards student-centred pedagogy : action research with Ethiopian village school teachers
2018
This study is an action research that was planned and implemented with 23 Ethiopian Village School teachers. The action of the four year project concentrated on developing new, student-centred teaching methods instead of traditional lecturing and rote learning in one remote school. The overall aim of the study was to follow this process and the teachers’ professional development, and to explore how the practical arrangements, such as material or cultural surroundings, constrain or enable usage of student-centred methods at the school. The theoretical framework of the study consists of theories about professional development, action research, and the theory of practice architectures. The dat…
