The Concept of Love in Masculinist Blogs : A Strategic Ideal

2018

Love is often considered a positive emotion and an ethical relationship between people. The representations of love in contemporary culture usually emphasise its beneficial, even empowering effects. However, the fluidity of the concept also enables other kinds of representations of love to flourish. For example, the advocates of traditional gender order — masculinists or male rights activists (MRAs)-— use idealistic images of heterosexual love, often intertwined with the idealised heterosexual nuclear family, to promote repressive ideologies such as misogyny and antifeminism. This is increasingly done with the help of internet sites. In this chapter I wish to show that the fluidity of the c…

Combining fuzzy C-mean and normalized convolution for cloud detection in IR images

2009

An important task for the cloud monitoring in several frameworks is providing maps of the cloud coverage. In this paper we present a method to detect cloudy pixels for images taken from ground by an infra-red camera. The method is a three-steps algorithm mainly based on a Fuzzy C-Mean clustering, that works on a feature space derived from the original image and the output of the reconstructed image obtained via normalized convolution. Experiments, run on several infra-red images acquired under different conditions, show that the cloud maps returned are satisfactory. © 2009 Springer Berlin Heidelberg.

Laryngeal Mask Airway Position and the Risk of Gastric Insufflation

1998

A potential risk of the laryngeal mask airway (LMA) is an incomplete mask seal causing gastric insufflation or oropharyngeal air leakage.The objective of the present study was to assess the incidence of LMA malpositions by fiberoptic laryngoscopy, and to determine their influence on gastric insufflation and oropharyngeal air leakage. One hundred eight patients were studied after the induction of anesthesia, before any surgical manipulations. After clinically satisfactory LMA placement, tidal volumes were increased stepwise until air entered the stomach, airway pressure exceeded 40 cm H2 O, or air leakage from the mask seal prevented further increases in tidal volume. LMA position in relatio…

Ēku 3D modeļu rekonstrukcija, izmantojot plakņu marķēšanas algoritmus un tālizpētes datus

2022

Pilsētvides problēmu risināšanā noderīgi ir ēku 3D (trīs dimensiju) modeļi, kas var tikt pielietoti pilsētas infrastruktūras plānošanā, scenāriju modelēšanā u.c. specifisku problēmu risināšanā. Darbs ir turpinājums autora bakalaura darbam, kurā tika piedāvāta metode ēku 3D modeļu izveidei. Tās galvenais trūkums ir nepieciešamība pēc lietotāja iejaukšanās, padarot metodi nepiemērotu plašai pilsētas 3D modelēšanai. Darba mērķis ir uzlabot jumta plakņu noteikšanas procesu, izmantojot mašīnmācīšanās metodes, un izstrādāt plašāk lietojamu ēku 3D modeļu ģenerēšanas algoritmu, kas būtu piemērots dažādām jumtu arhitektūrām. Darba rezultātā tiek apmācīts Mask R-CNN konvolūciju neironu tīkls jumta pl…

Vibrasjonsanalyse : Feildeteksjon i Kulelager: Prosessering av Vibrasjonssignaler, Algoritmer, og Envelope Spektrum

2017

Masteroppgave fornybar energi ENE500 - Universitetet i Agder 2017 The report deals with fault detection and diagnosis of roller element bearings. Vibration and shaft position sensor data combined with three algorithms are tested to determine which combination may detect bearing faults early and reliably. Experimental data from an accelerated life-time test is used to verify the performance. Results show that the vibration signal combined with a fast spectral correlation algorithm yields the most reliable diagnosis.

Airway management techniques in a restricted-access situation: a manikin study

2016

Background Access to patients can be restricted in emergency situations. A variety of techniques and devices are available for use in patients who require oxygenation in a restricted-access situation. Objectives The aim of this study was to investigate whether there is one ventilation technique that is superior to others. Materials and methods Fifty-four emergency medical services providers including emergency medical technicians, paramedics and physicians were asked to use a bag-valve mask (BVM), a laryngeal mask airway (LMA), and a laryngeal tube (LT) to ventilate a full-scale manikin sitting upright in the driver's seat of a motor vehicle. Access to the manikin was gained through the sid…

Gastric insufflation pressure, air leakage and respiratory mechanics in the use of the laryngeal mask airway (LMA) in children.

2004

Summary Background : The objective of the present study was to evaluate the prelaryngeal position of the laryngeal mask airway (LMATM) in children, and to determine the influence of mask positioning on gastric insufflation and oropharyngeal air leakage. Methods : A total of 100 children, 3–11 years old, scheduled for surgical procedures in the supine position under general anaesthesia were studied. After clinically satisfactory LMA placement, tidal volumes were increased stepwise until air entered the stomach, airway pressure exceeded 30 cmH2O, or air leakage from the mask seal prevented further increases in tidal volume. LMA position in relation to the laryngeal entrance was verified using…

Breaking down the word length effect on readers’ eye movements

2015

Previous research on the effect of word length on reading confounded the number of letters (NrL) in a word with its spatial width. Consequently, the extent to which visuospatial and attentional-linguistic processes contribute to the word length effect on parafoveal and foveal vision in reading and dyslexia is unknown. Scholars recently suggested that visual crowding is an important factor for determining an individual’s reading speed in fluent and dyslexic reading. We studied whether the NrL or the spatial width of target words affects fixation duration and saccadic measures in natural reading in fluent and dysfluent readers of a transparent orthography. Participants read natural sentences …
