Detta arbete kick-startar AI (artificiell intelligens) för ledningsunderhåll i VA-branschen i Sverige. Arbetet med befintliga VA-nät är idag främst reaktivt; man reparerar läckor vartefter man blir varse dem, ibland till stora kostnader om läckan är omfattande och akut. Med denna artikel vill vi sätta fokus på proaktivt arbete med ledningsnät och diskutera riskanalys inom området. En ANN-modell soThis work kick-starts AI (artificial intelligence) for pipe management among Swedish water utilities. The current work with pipe management is mainly reactive; leaks are repaired after they are detected, sometimes with large costs if the leakage is extensive and critical. With this article, we want to focus on proactive pipe network management and discuss risk analysis in the field. A previously d

As part of the “enlightened” reform activity, Gustav III issued a Tolerance Edict for “foreign believers” in 1781. This law allowed Catholic immigrants to publicly practice their religion. The members of the Reformed communities had already been granted the same rights, and in 1782 the ban on Jewish immigration was abolished. According to previous research, these edicts of toleration, in addition

Pragmadialektiikan maailmanvalloitus alkoi kaksikymmentäviisi vuotta sitten. Tänään se on yhtä tunnettu kuin jo viisikymmentä vuotta täyttäneet Toulminin ja Perelmanin uraauurtavat argumentaation teoriat. Arviot pragmadialektiikasta kuitenkin vaihtelevat huomattavan paljon. J. Anthony Blair on esimerkiksi luonnehtinut sitä maailman tärkeimmäksi argumentaation teoriaksi tänä päivänä. John Woodsin m

Broar över vattendrag utgör viktiga element i många transportsystem. Om broar kollapsar orsakas betydande problem med både direkta och indirekta kostnader för samhällsekonomin. Lokal erosion av botten kring broar är många gånger en huvudorsak till brokollaps, ofta i samband med extrema flödessituationer. Risken för sådan lokal erosion kan bli större i samband med en framtida klimatförändring, vilkBridges are important components in many transportation networks often spanning rivers and other water bodies. The failure of a bridge will cause significant direct and indirect economic losses to society. Scouring of the river bed around bridges is a principal mode of bridge failure typically associated with large floods. The risk of such scour may become higher with the emerging climate change t

ATT PLÖJA MYCKET, LITE ELLER INGET ALLS Vi blir fler och fler människor på vår planet, och år 2050 beräknas vi vara så många som 10 miljarder. Det innebär att vi måste kunna producera mer mat på en lika stor eller till och med mindre yta jämfört med idag. En stor del av den mat vi konsumerar produceras antingen direkt eller indirekt på åkrar runt om i världen. För lantbrukare som är inriktade på vSoil microorganisms are important for climate regulation as well as for plant nutrition. In agricultural soils the microorganisms are affected by management choices, like which type of tillage that is used. Moldboard plowing, the most common tillage practice, increases mineralization which leads to soil organic carbon (SOC) loss, and may thus reduce soil quality. Conservation tillage practices inf

Within the project LATERES COCTILES early fired bricks have been the objectof a multifaceted investigation. One aim has been to elucidate the mechanisms behind the diffusion of this innovation. An inventory of Hellenistic and early Roman fired bricks around the Mediterranean resulted in an archaeological database comprising 276 brick contexts. Network analysis was applied to these data using a two

Deliberate self-harm behavior (DSH) can have profound effects on a person’s quality of life, and challenges the health care system. Even though DSH has been associated with aggressive interpersonal behaviors, the knowledge on DSH in persons exhibiting such behaviors is scarce. This study aims to (1) specify the prevalence and character of DSH, (2) identify clinical, neurocognitive, psychosocial, a

Due to the significant increase in pediatric trunk computed tomography (CT) examinations, there is a need for a reliable approach of conducting effectivedose estimate for such procedures. The current study is based on two dosimetric anthropomorphic phantoms representing a 1-year and a 5-year old child. Effectiveand equivalent tissue doses from CT examinations of the trunk were determined by thermo

Establishing diagnostic reference levels (DRLs) in a big country is complicated due to differences in radiological practice between different regions. In 2009-2014, a dose survey was performed in six Russian regions. Based on the results of the survey, preliminary DRLs for conventional X-ray examinations were established on a national level. Additionally, the local authorities were granted the pos
