  • 6G E2E Architecture Framework with Sustainability and Security Considerations
  • 2022
  • In: 2022 IEEE GLOBECOM Workshops, GC Wkshps 2022 - Proceedings. ; , s. 832-837
  • Conference paper (peer-reviewed)abstract
    • The research on 6G in the EU-funded flagship project Hexa-X started with the investigation of the most important technology enablers and the evaluation of relevant 6G use cases. The next step is to integrate these enablers in a 6G E2E architecture that fulfills all use case-based Key Performance (KPI) and Key Value Indicators (KVI) and that follows the guidelines of general architectural principles. In addition, the main focus of an E2E 6G architecture must be on security and sustainability which both will have increased importance for future communication networks and society.

  • Automatic Detection of Burn-through in GMA Welding Using a Parametric Model
  • 1996
  • In: Mechanical Systems & Signal Processing. - London : Academic Press. - 0888-3270. ; 10:5, s. 633-651
  • Journal article (peer-reviewed)abstract
    • This paper addresses the problem of automatic detection of burn-through in weld joints. Gas metal are (GMA) welding with pulsed current is used, and welding voltage and current are recorded. As short-circuitings are common between the welding electrode and the work piece during burn-through, a short-circuit detector is developed to detect these events. To detect another specific characteristic of burn-through-a broadband long-lasting voltage component-this detector is combined with a square-law detector. This second detector is based on a non-linear modification of an autoregressive model with extra input (ARX-model) of the welding process. The results obtained from this compound detector indicate that it is possible to detect burn-through in the welds automatically. The work also indicates that it is possible to design an on-line monitoring system for robotic GMA welding.

  • Lärobok i Militärteknik, vol. 9 : Teori och metod
  • 2013. - 1
  • Book (other academic/artistic)abstract
    • Ämnet militärteknik utgår från att tekniska system är officerens arbetsredskap och att en förståelse för och kunskap om dessa verktyg är central för att kunna utöva professionen framgångsrikt. Denna nionde volym av Lärobok i Militärteknik, benämnd Teori och Metod, behandlar centrala begrepp, teorier och postulat samt metoder för värdering av teknik och består av ett antal texter författade av 16 forskare och lärare vid den militärtekniska avdelningen. Volymen riktar sig främst till de som inlett sin officersutbildning och utgörs till stora delar av ett kompilat av publicerade och opublicerade militärtekniska texter och kan sägas utgöra militärteknikens ”state of the art”.

  • Injuries in rock climbing : An epidemiological study of the Swedish climber population
  • 2008
  • Conference paper (peer-reviewed)abstract
    • Objective.The popularity of rock climbing is increasing worldwide, both as a recreational physical activity and as a competitive sport. By its nature, rock climbing is associated with injury risks. We aimed to examine typical injury patterns in a representative sample from a total population of climbers.Material and methods.A mail survey was distributed to a random sample consisting of 10 % of the Swedish Climbing Association membership (597/6067 persons). Self-reported information about climbing history, safety practices, and retrospective accounts of injury events were obtained.Results.The annual incidence of overuse injuries was 280/1000 climber years. Inflammatory tissue damage to the fingers and wrists were most common injury types. Men and climbers practising bouldering or sport climbing reported more overuse injuries. The incidence of acute injuries was considerably lower (25/1000 climber years). Men were represented twice as often as women in this group. Twenty-four percent of climbers reporting overuse injuries also suffered an incident or acute injury that same year. The largest number of acute injuries occurred during traditional climbing. These injuries were commonly localised to the feet and ankles. The most frequent cause reported to explain the acute injuries was the human factor, i.e. mistakes or lapses.Discussion and conclusions.Overuse injuries are common among climbers, while acute injuries are less common but can lead to long absence from climbing. Both types of injuries can be reduced by focussed prevention programs. While overuse injuries can be reduced by a better balance between climbing activity and rest, systematic information about safety practices and participation in mandatory first aid and climbing rescue courses can reduce acute injuries and their consequences.

  • Effect of nitric oxide on histamine-induced cytological transformations in parietal cells in isolated human gastric glands
  • 2007
  • In: Digestive Diseases and Sciences. - : Springer Science and Business Media LLC. - 0163-2116 .- 1573-2568. ; 52:1, s. 126-136
  • Journal article (peer-reviewed)abstract
    • Previous studies have shown that nitric oxide (NO) inhibits histamine-induced gastric acid secretion in isolated human gastric glands. NO synthase has been found to be present in the human oxyntic mucosa and has been suggested to serve as a paracrine regulator of gastric acid secretion. Histamine stimulation of parietal cells induces cytoskeletal rearrangements, recruitment of H +/K +-ATPase-rich tubulovesicles to the apical membrane and expansion of intracellular canaliculi. The aim of the present study was thus to investigate (i) the effect of an NO donor on histamine-induced cytological transformations and (ii) the influence of increased [Ca 2+] i on NO-induced morphological changes in human parietal cells. Human gastric glands were isolated and subjected to the NO donor SNAP prior to histamine administration. [Ca 2+] i was increased by photolysis of the caged Ca 2+ compound NP-EGTA. The distribution of F-actin, ezrin, and H +/K +-ATPase was assessed by confocal microscopy. Ultrastructural analysis was performed using transmission electron microscopy. SNAP did not influence the histamine-induced translocation of F-actin, ezrin, and H +/K +-ATPase but prevented an increase in the canalicular size. Elevation of [Ca 2+] i in resting cells was found to mimic histamine-induced intraparietal cell transformations; however, NO-induced parietal cell morphology was unaffected by a rise in [Ca 2+] i. These results indicate that NO inhibits secretion of fluid into the canalicular lumen without affecting membrane recruitment and that this effect is Ca 2+-insensitive. © 2006 Springer Science+Business Media, Inc.

  • Nitric oxide-an endogenous inhibitor of gastric acid secretion in isolated human gastric glands
  • 2004
  • In: BMC Gastroenterology. - 1471-230X. ; 4:16
  • Journal article (peer-reviewed)abstract
    • BackgroundEndothelial nitric oxide synthase (eNOS) has previously been detected in the glandular part of the human gastric mucosa. Furthermore, nitric oxide (NO) has been shown to influence gastric secretion in various animal models. The present study was conducted to investigate the influence of exogenously and endogenously derived NO on histamine- and cAMP-stimulated gastric acid secretion in isolated human oxyntic glands.MethodsOxyntic glands were isolated from human gastric biopsies and were subsequently pre-treated with NO donors and nitric oxide synthase inhibitors and then exposed to histamine or dibutyryl-cAMP (db-cAMP). The secretory response of the glands was determined as accumulation of [14C]aminopyrine.ResultsThe histamine- or db-cAMP-induced acid secretion was attenuated by L-arginine, a known source of endogenous NO, and also by the NO-donors sodium nitroprusside (SNP) and S-nitroso-N-acetyl-penicillamine (SNAP). Pre-treatment with either of the NOS inhibitors NG-nitro-L-arginine methyl ester (L-NAME) or NG-nitro-L-arginine (L-NNA) enhanced the secretory response.ConclusionOur results show that NO inhibits gastric acid secretion in isolated human gastric glands, and that there is endogenous formation of NO within the glandular epithelium in the vicinity of the parietal cells.
