Compared to the highly developed logistics industry in USA, the Chinese logistics industry is still underdeveloped because of poor infrastructure and ineffective management capability. In terms of these realities, the most important bottleneck of the Chinese logistics industry is the last mile delivery problem, which holds the highest cost in the whole logistics process. To find ways to solve the problems with last mile delivery has become significant and urgent for Chinese logistics service providers. The purpose of the study is to deepen and enrich the knowledge on last mile logistics in China. This is carried out with the help of the case companies SF Express and Property Management Company together with an investigation of last mile delivery alternatives in China. Related to the research question, a case study was carried out focusing on one business process. The data collection methods used include: interview, telephone or email contact, and survey. Intelligent locker and the pick-up delivery solution could solve last mile logistics problems by different ways, especially with specific limitations in Chinese market. These delivery alternatives are highly possible to be adopted and generalized by different logistics service providers in China if not concerned about the cost or density of orders. The current business mode of supermarket in China cannot fulfill the demand from an overwhelming number of customers. Costs for both pick-up stations are acceptable, and the cost is a positive factor for pick-up station mode. The higher density of orders, the higher possibility of different time-window may require, and high competitive advantage of intelligent locker can be achieved. The high density of orders for intelligent locker is a positive factor. The cost for intelligent locker is a very negative factor, which seriously limits the popularization of this delivery alternative.

Syftet med denna studie var att undersöka elevernas inställning till att duscha i samband med idrott och hälsa i skolan. Syftet var också att undersöka huruvida eleverna upplever att valet att inte duscha kan påverka det aktiva deltagandet på idrottslektionen. Frågeställningarna i studien är: Finns någon skillnad i inställningen till att duscha i samband med idrottslektionen hos elever i årskurs fem, sju och nio? Upplever eleverna i årskurs fem, sju och nio att valet att inte duscha i samband med idrotten blir ett hinder för att delta aktivt på idrottslektionen? Studien har en kvantitativ ansats med frågeformulär som datainsamlingsmetod. Urvalsgruppen bestod av 128 elever ur årskurs fem, sju och nio på en grundskola i Sverige. Resultatet visade att ju äldre eleverna var desto oftare valde de att inte duscha i samband med idrottslektionen. De äldre eleverna ansåg det också vara mindre viktigt att duscha efter idrottslektionen än de yngre. Resultatet visade även att valet att inte duscha efter idrottslektionen kan bli ett hinder för aktivt deltagande men att det inte alltid var så. / The purpose of this study was to examine students’ attitude regarding showering following lessons in physical education. The purpose was also to examine whether the students consider the choice of not showering following lessons in physical education can influence their active participation. The study seeks to answer the questions: Is there a difference in attitude between students in fifth, seventh and ninth grade regarding showering following lessons in physical education? Do the students in fifth, seventh and ninth grade consider that the choice of not showering following lessons in physical education becomes an obstacle for active participation? The study has a quantitative approach and the method used for the gathering of data was questionnaires. The selection group consisted of 128 students from fifth, seventh and ninth grade at an elementary school in Sweden.   The results showed that the older the students were, the more often they chose not to shower following lessons in physical education. The older students also considered it to be less important to shower after lessons in physical education than the younger students did. The results also showed that the choice of not showering following lessons in physical education could represent an obstacle for active participation but not always.

This master thesis is a study of anaerobic thread lockers and is done in cooperation withÖhlins Racing AB, which is a Swedish manufacturer of vehicle suspensions.The suspension in vehicles is constantly exposed to high vibration levels and a suspensionunit has several screw- and cylindrical joints. As an extra safety precaution so that thecomponents in the suspension doesn’t fall apart when using the vehicle, an anaerobicthreadlocker is added in these joints. The handling of these threadlockers is not totallyharmless and could lead to allergic reactions, and therefore there are Swedish laws to limit theuse of these. However, new types of anaerobic threadlockers have recently been launched onthe marked that are not considered under this law. The goal of this thesis is to investigate if itwould be possible to change from the today used threadlockers to these new types. A big partof this task has been based on tests of screw- and cylindrical joints. Different materialcombinations of aluminum, anodized aluminum and steel have been tested, as well asparameters such as elevated temperature. The breakloose torque for the thread joints, and theforce required to axially break a cylindrical fitting has been analyzed.Tests were performed with both medium- and high-strength anaerobic threadlockers ofdifferent brands. The results from the screw joint tests with a medium strength threadlockershow that the new health-friendly threadlockers are about as good as the ones used today,except at high temperatures. Considering the high strength threadlockers in aluminum screwjoints, the reference threadlocker showed about 10 – 30 % higher breakloose torque than thehealth-friendly one, depending on the different material combinations. With the steel –aluminum screw joints, the breakloose torque reduced to about half of the aluminum –aluminum breakloose torque values for both types of threadlockers. The results also show thata thicker layer of anodized aluminum gave a higher breakloose torque and that temperaturesof about 85 oC lower the strength with 22 – 29 % compared to the tests in room temperature.In the case with the cylindrical joints, the health friendly ones were weaker than the one usedtoday, but it might still be possible to use them in some products.The conclusions of this thesis are that the health-friendly threadlockers in general are a bitweaker than the ones used today, and that anodized aluminum gives a higher breakloosetorque than both aluminum and steel. It is likely that a change from the threadlockers usedtoday to the new health-friendly ones could be possible in at least some joints. Although moretests have to be done with dynamic loads and oil resistance for example. / Detta examensarbete är en undersökning av anaeroba låsvätskor som utförts i samarbete medÖhlins Racing AB. Öhlins Racing AB är ett svenskt företag som tillverkar högpresterandestötdämpare och fjädring till bland annat motorcyklar och bilar.Stötdämpare i fordon utsätts för mycket höga vibrationsnivåer och för att kunna garanterastötdämparnas kvalitet och livslängd är det av stor vikt att säkerställa att dess komponenterinte lossnar vid användandet. Många komponenter sitter monterade med gängförband ellercylindrisk passning och vid montering tillsätts en låsvätska som en extra säkerhetsåtgärd.Hanteringen av dessa låsvätskor kan leda till hälsoproblem som allergier och luftvägsproblem.Målet med detta arbete är att undersöka om det är möjligt att införa mer arbetsmiljövänligalåsvätskor i Öhlins produkter. Arbetet har bestått av provning med gäng- och cylinderförbanddär olika materialkombinationer av aluminium, anodiserat aluminium och stål, samtparametrar som temperatur har varierats i de olika testuppställningarna. Urpressningskraftenför cylinderförbanden och lossbrytningsmomentet för gängförbanden har analyserats.Tester utfördes med starka och medelstarka låsvätskor av olika fabrikat. Resultaten fråntesterna med gängförband visar att de medelstarka låsvätskorna är mycket likvärdiga, medundantag för högtemperaturtestet där den arbetsmiljövänliga låsvätskan ger sämre resultat.Gällande de starka låsvätskorna i aluminiumförband ger den nu använda låsvätskan 10–30 %högre lossbrytningsmoment än den arbetsmiljövänliga varianten. I förbandet stål – aluminiumvisade det sig att de starka låsvätskornas lossbrytningsmoment över lag låg omkring hälftenjämfört med aluminiumfallet. Resultaten visar också att ett tjockare anodiseringsskikt påaluminiumet ger högre lossbrytningsmoment samt att lossbrytningsmomentet sjunker med 22- 29 % vid temperaturer omkring 85 oC jämfört med i rumstemperatur. I det cylindriska falletkommer de arbetsmiljövänliga låsvätskorna inte upp i samma höga urpressningskraft som denidag använda låsvätskan, men de kan trots detta vara tillräckligt bra för att användas i mångaförband.De slutsatser som kan dras efter detta projekt är att de arbetsmiljövänliga låsvätskornagenerellt sett är lite svagare än den låsvätska som används idag, samt att anodiserataluminium gav högre lossbrytningsmoment än obehandlat aluminium och stål. Det skulleförmodligen vara möjligt att byta ut låsvätskan till arbetsmiljövänlig låsvätska i mångaförband där det inte ställs krav på extremt hög hållfasthet. Det bör dock undersökas närmarehur bland annat dynamiska lastfall och kontakt med olja påverkar låsvätskorna.

Yes / The lack of separation between urgent and non-urgent medical goods encourages sub-optimal vehicle fleet operations owing to the time critical nature of urgent items. An unattended electronic locker bank, to which individual urgent items can be delivered thereby separating urgent and non-urgent supply, was proposed for the Great Ormond Street Hospital in London, UK. This concept was quantified using ‘basic’ and ‘intuitive’ hill climbing optimisation models; and qualitatively using staff interviews and expert reviews. Results indicated that a locker bank with a fixed height (1.7 m) and depth (0.8 m) required a length of 4 m (basic model) and 3.63 m (intuitive model), to accommodate 100% of urgent consignments for a typical week. Staff interviews indicated the wider benefits such as staff personal deliveries.

This doctoral thesis represents pioneering research in integrating Smart Mobile Lockers with City Buses (SML-CBs) for e-commerce last-mile delivery, a novel concept rooted in the sharing economy. It explores the innovative use of underutilized urban bus capacities for parcel transportation while incorporating smart parcel lockers to facilitate self-pick-up by customers. Comprising six chapters, the thesis delineates its background, motivations, contributions, and organization in Chapter 1. Chapter 2 presents a comprehensive review of the recent literature on last-mile freight deliveries, including a bibliometric analysis, identifying gaps and opportunities for SML-CBs intervention. In Chapter 3, using survey data, we conduct empirical analytics to study Canadian consumers’ attitudes towards adopting SML-CBs, focusing on deterrents such as excessive walking distances to pick-up locations and incentives led by environmental concerns. This chapter also pinpoints demographic segments likely to be early adopters of this innovative delivery system. To address the concerns over walking distances identified in Chapter 3, Chapter 4 presents a prescriptive model and algorithms aimed at minimizing customer walking distance to self-pick-up points, considering the assignment of SML-CBs and customers. The case study results endorse the convenience of SML-CBs in terms of short walking distances. To systematically assess the sustainability benefits, a key motivator identified in Chapter 3, Chapter 5 includes analytical models for pricing and accessibility of SML-CBs. It also employs a hybrid life cycle assessment (LCA) methodology to analyze the sustainability performance of SML-CBs. It establishes system boundaries, develops pertinent LCA parameters, and illustrates substantial greenhouse gas (GHG) savings in both operational and life cycle phases when SML-CBs are utilized instead of traditional delivery trucks. The dissertation is concluded in Chapter 6, summarizing the principal contributions and suggesting avenues for future research. This comprehensive study not only provides empirical and analytical evidence supporting the feasibility and advantages of SML-CBs but also contributes to the literature on sustainable logistics and urban freight deliveries. / Thesis / Doctor of Philosophy (PhD) / This doctoral thesis represents pioneering research in integrating Smart Mobile Lockers with City Buses (SML-CBs) for e-commerce last-mile delivery.
