N,N-Dimethyl-N-propylpropan-1-aminium chloride monohydrate
2008
The title compound, C8H20N+·Cl−·H2O, has been prepared by a simple one-pot synthesis route followed by anion exchange using resin. In the crystal structure, the cations are packed in such a way that channels exist parallel to the b axis. These channels are filled by the anions and water molecules, which interact via O—H...Cl hydrogen bonds [O...Cl = 3.285 (3) and 3.239 (3) Å] to form helical chains. The cations are involved in weak intermolecular C—H...Cl and C—H...O hydrogen bonds. The title compound is not isomorphous with the bromo or iodo analogues.
Towards CCTV-aware Routing and Navigation for Privacy, Anonymity, and Safety - Feasibility Study in Jyväskylä
2021
AbstractIn order to withstand the ever-increasing invasion of privacy by CCTV cameras and technologies, on par CCTV-aware solutions must exist that provide privacy, safety, and cybersecurity features. We argue that a first important step towards such CCTV-aware solutions must be a mapping system (e.g., Google Maps, OpenStreetMap) that provides both privacy and safety routing and navigation options. Unfortunately, to the best of our knowledge, there are no mapping nor navigation systems that support CCTV-privacy and CCTV-safety routing options. At the same time, in order to move the privacy vs. safety debate related to CCTV surveillance cameras from purely subjective to data-driven and evide…
Why Use Interactive Multi-Objective Optimization in Chemical Process Design?
2008
Problems in chemical engineering, like most real-world optimization problems, typically, have several conflicting performance criteria or objectives and they often are computationally demanding, which sets special requirements on the optimization methods used. In this chapter, we point out some shortcomings of some widely used basic methods of multi-objective optimization. As an alternative, we suggest using interactive approaches where the role of a decision maker or a designer is emphasized. Interactive multi-objective optimization has been shown to suit well for chemical process design problems because it takes the preferences of the decision maker into account in an iterative manner tha…
The Joint Distribution Criterion and the Distance Tests for Selective Probabilistic Causality
2010
A general definition and a criterion (a necessary and sufficient condition) are formulated for an arbitrary set of external factors to selectively influence a corresponding set of random entities (generalized random variables, with values in arbitrary observation spaces), jointly distributed at every treatment (a set of factor values containing precisely one value of each factor). The random entities are selectively influenced by the corresponding factors if and only if the following condition, called the joint distribution criterion, is satisfied : there is a jointly distributed set of random entities, one entity for every value of every factor, such that every subset of this set that corr…
Dynamic assessment of word derivational knowledge: Tracing the development of a learner
2016
The present paper reports on a case study that explored the applicability of dynamic assessment (DA) for promoting learners’ word derivational knowledge in English as a second or a foreign language (L2). One learner’s performance on tasks assessing his word derivational knowledge was measured four times. The first two measurements were conducted before and after three weekly human-mediated DA sessions and the last two, which took place a year and a half later, before and after three weekly computerised DA sessions. Think aloud protocols and interviews were used to trace changes in the learner’s use of strategies and knowledge sources. The results revealed that following the dynamic assessme…
Cognitive Linguistics as the Underlying Framework for Semantic Annotation
2012
In recent years many attempts have been made to design suitable sets of rules aimed at extracting the semantic meaning from plain text, and to achieve annotation, but very few approaches make extensive use of grammars. Current systems are mainly focused on extracting the semantic role of the entities described in the text. This approach has limitations: in such applications the semantic role is conceived merely as the meaning of the involved entities without considering their context. As an example, current semantic annotators often specify a date entity without any annotation regarding the kind of the date itself i.e. a birth date, a book publication date, and so on. Moreover, these system…
Automated Detection of Microaneurysms Using Scale-Adapted Blob Analysis and Semi-Supervised Learning
2014
International audience; Despite several attempts, automated detection of microaneurysm (MA) from digital fundus images still remains to be an open issue. This is due to the subtle nature of MAs against the surrounding tissues. In this paper, the microaneurysm detection problem is modeled as finding interest regions or blobs from an image and an automatic local-scale selection technique is presented. Several scale-adapted region descriptors are then introduced to characterize these blob regions. A semi-supervised based learning approach, which requires few manually annotated learning examples, is also proposed to train a classifier to detect true MAs. The developed system is built using only…
Apple, Ibm and Microsoft in a war of signs
2007
The aim of my paper is exploring how image contributes on building the brand identity of specific organisations and how the meaning of the image can be resignified by the action of the players in a specific market. In particular, I will focus on the competition between three brands, Ibm, Apple, Microsoft. on the information technology market. My work is looking forward to be a continuation of the essay “Le vie du Logo” published in “Identités visuelles” by Jean Marie Floch about the visual competition between Apple and Ibm. I will use the tools of sociosemiotics, plastic and figurative analysis, screening more than 20 years of competition starting from 1984, the year in which the analysis o…
Towards Equivalence Links between Senses in PlWordNet and Princeton WordNet
2017
AbstractThe paper focuses on the issue of creating equivalence links in the domain of bilingual computational lexicography. The existing interlingual links between plWordNet and Princeton WordNet synsets (sets of synonymous lexical units – lemma and sense pairs) are re-analysed from the perspective of equivalence types as defined in traditional lexicography and translation. Special attention is paid to cognitive and translational equivalents. A proposal of mapping lexical units is presented. Three types of links are defined: super-strong equivalence, strong equivalence and weak implied equivalence. The strong equivalences have a common set of formal, semantic and usage features, with some o…
Servera uzstādīšana nelielam birojam
2015
Šī darba mērķis ir nelielam birojam izveidot serverus ar dažādām lomām ar virtuālo mašīnu palīdzību. Servera pamatā būs Windows Server 2012 R2 Standart. Serveriem jābūt uzstādītiem kvalitatīvi. Uz serveriem tiek uzstādīta nepieciešamā programmatūra šī biroja vajadzībām, bet šāda programmatūra var noderēt gandrīz visos parastos birojos. Darba uzdevumos arī ietilpst izveidot drošu un regulāru rezervju kopiju veidošanu. Kā arī jānodrošina tīkla drošība no dažādiem draudiem un vīrusiem, tas ir izdarāms ar pretvīrusu programmām un ugunsmūriem.
