This research has investigated the conditions necessary for atmospheric-induced stress corrosion cracking to occur in material taken from an intermediate level nuclear waste storage container by means of experiments in a humidity chamber. It has also characterised the residual stresses associated with the container welds by modelling and measurement. Based on the work conducted in this research, the major findings can be summarised as follows:• Deliquescence of salt particles is dependent on relative humidity but independent of the quantity of salt present.• The time to initiate cracking may be sensitive to temperature, getting longer as the temperature decreases, but the timeframe of work as not long enough to establish this conclusively.• AISCC can occur at a stress (residual or applied) of 400MPa (0.2% strain) or more if the other necessary conditions are present. While AISCC was not observed when no stress was present, the threshold of stress below which AISCC will definitely not occur has not been determined in this work.

Edge computing and CAV (Connected Autonomous Vehicle) fields can work as a team. With the short latency and high responsiveness of edge computing, it is a better fit than cloud computing in the CAV field. Moreover, containerized applications are getting rid of the annoying procedures for setting the required environment. So that deployment of applications on new machines is much more user-friendly than before. Therefore, this paper proposes a framework developed for the CAV edge computing scenario. This framework consists of various programs written in different languages. The framework uses Docker technology to containerize these applications so that the deployment could be simple and easy. This framework consists of two parts. One is for the vehicle on-board unit, which exposes data to the closest edge device and receives the output generated by the edge device. Another is for the edge device, which is responsible for collecting and processing big load of data and broadcasting output to vehicles. So the vehicle does not need to perform the heavyweight tasks that could drain up the limited power.

Detta arbete utvärderar nyttan av att konstruera ett kluster med ett företags eller en organisations befintliga datorer. Klustret baserat på vanliga persondatorer kan blisom ett alternativ att driftsätta applikationer och tjänster. Alternativet är i stället föratt införskaffa serverar och högprestandadatorer. Detta kan bidra till att minska kostnader och återanvända resurser som redan finns. Arbetet mäter klustrets prestanda och effektivitet, därefter jämför resultatet med andra datorer och system. Arbetet utförs hos Syntronic och Högskolan i Gävle, där arbetet använder sig av de resurser som både parterna har och arbetet konstruerar varsitt kluster att mäta med.Resultatet visar att ett kluster byggd av datorer från Syntronic och högskolan presterar jämförbart med konsumentklassade processorer som kan hittas i nya datorer. Resultatet visar dock att bägge klustren har varken någon ekonomisk eller ekologisk fördel jämfört med nya datorer. Det är mer gynnsamt att sälja av Syntronics och Högskolans datorer i andrahandsmarknaden, för att sedan införskaffa nya datorer. / This thesis evaluates a cluster according to energy efficiency and performance. A cluster made of computers that a company, or an organization already owns, without purchasing any computers. The cluster based on older commodity computersacts as an alternative for operating and running software instead of buying server or high-end hardware. Reason for creating a cluster out of existing computers is mainly for reducing expenses and reuse hardware that otherwise considers as waste. This thesis measures the clusters performance and efficiency, then compares the results with other hardware and systems. This thesis uses computers from Syntronic and University of Gävle. This thesis creates a cluster each, one at Syntronic, one at University of Gävle and then measures them. The result shows that a cluster made of Syntronics computer performs equally amongst systems with a consumer grade processor. This thesis also shows that both clusters are not a viable option from an economic and environmental perspective. It is more beneficial to sell those computersfrom Syntronic and the University, for then to purchase new hardware.

Two dormancy induction trials were conducted in a private container nursery in Saanichton, British Columbia. The first study examined the effects of photoperiod induced dormancy on morphology, root growth and field performance of fall planted western hemlock (Tsuga heterophyl_1ji (Raf.)Sarg.) and Douglas-fir (Pseudotsuga menzi_esv[ (Mirb.) Franco) seedlings. Various periods of eight hour days, ranging from two to eight weeks, were applied throughout July and August 1983. Outplanting was done in late September. Survival and growth were assessed one year later. The second project investigated the effectiveness of short days, varying levels of moisture stress and a combination of both as dormancy induction techniques for Douglas-fir seedlings. The short day treatment was four weeks of eight hour days. Four levels of predawn moisture stress were: -5, -10, -15 and -25 bars. These classes respectively corresponded to control, light, medium and severe moisture stress levels. Short days and moisture stress were also combined whereby the four week period of short days followed the moisture stress treatments. These induction treatments were applied in July and August 1984. All seedlings were lifted in January 1985 and placed into cold storage for five weeks until March 1985. Morphology, root growth capacity, frost hardiness and dormancy intensity were assessed in January. Root growth capacity and dormancy intensity were again measured in March. In Study I, short days quickly initiated homogeneous budset in both species in approximately three weeks. The average height increment after treatment initiation was 3.7 cm in Douglas-fir and 4.2 cm in western hemlock. Short days reduced shoot dry weight and height. Caliper and root dry weight were unaffected. In September a surge in root growth occurred in hemlock seedlings treated with six or eight weeks of short days. The importance of early budset to allow increased root growth prior to a fall lift was demonstrated. Root growth capacity was similar among all treatments for both species. The planting survival of western hemlock seedlings increased with increasing weeks of short days. Control plants had 76% survival while the eight week regime had 91%. Survival was similar for all treated Douglas-fir seedlings. It ranged from 89% in the two week interval to 98% in the four week regime. One year height increment was significantly greater in the six and eight week short day treatments for both species. For hemlock, it ranged from 6.1 cm in the control plants to 10.4 cm in the six week trees. Douglas-fir height increment ranged from 6.4 cm for the control interval to 8.6 cm in the eight week regime. The six and eight week photoregimes produced the best quality hemlock seedlings for this study. Four weeks of short days appeared adequate for Douglas-fir. In Study II short days effectively initiated and maintained budset in Douglas-fir seedlings in four weeks. After six weeks from treatment initiation, a light to severe moisture stress was as effective in controlling height growth. A natural photoperiod with no moisture stress was least effective. In a comparison of all treatment combinations, only the control plants under a natural photoperiod were significantly larger in all morphological properties. Short days, moisture stress or a combination of both had similar effects on reducing height, caliper, shoot dry weight and root dry weight. Unstressed seedlings in a natural daylength had the highest value of root growth capacity. All other treatment combinations had significantly lower root growth capacity. Only the severe stress under a natural photoperiod significantly reduced root growth capacity compared to any other treatment. Short days accelerated bud burst in the January and March dormancy intensity tests. Frost hardiness was similar among all treatments. Selection of a regime which controlled height growth while maintaining seedling quality was not clearcut. A short photoperiod with no moisture stress was most effective in initiating budset. However, few morphological and physiological differences were evident between short day plants and light and medium stressed seedlings. / Forestry, Faculty of / Graduate

Oxelösunds hamn har identifierat den kombinerade depån och terminalen de driver i Stålhamnen, Oxelösund, som en trång sektor. Depån och terminalen undersöktes med hänseende på hur den fysiska hanteringen påverkar uppfattningen om att de bidrar till att ytan de bedrivs på ses som en trång sektor. Även informationsflödet kartlades för att dels undersöka hur containrar fraktas till och från depån samt hur frakten initieras och hur det påverkar trångheten. Undersökningen tog sin ståndpunkt i ett systemsynsätt genom intervjuer och deltagande i verksamheten som Oxelösunds hamn bedriver på ytan. Genom intervjuer och deltagande i verksamheten har både dokumenterade och odokumenterade aktiviteter identifierats gällande både den fysisk hanteringen och informationsflödet. Under arbetets gång blev det även tydligt att alla personer som kommer i kontakt med antingen den fysiska hanteringen eller informationsflödet inte nödvändigtvis har samma syn på systemet. Ibland saknas en helhetssyn över systemet och man känner endast till sina närmsta parter i kedjan. I dagsläget är det osäkert hur avsaknaden av helhetssyn påverkar den fysiska hanteringen och informationsflödet på och kring ytan. Det är dock ingen fråga om huruvida det påverkar eller ej, för på något vis medför avsaknaden av kännedom om systemet problem i det. Resultatet pekar på att det finns förbättringspotential i både den fysiska hanteringen såväl som informationsflödet mellan de tre företagen som gör att depån och terminalen fungerar som den ska. Resultatet pekar även på att ytan som depån och terminalen idag bedrivs på inte är den trånga sektor Oxelösunds hamn antagit den varit. Depån och terminalen är inte en trång sektor då ytan idag ska ha en överkapacitet gentemot de verksamheter som de servar i antal containrar per år som kan passera.
