This study focuses on different manufacturing processes and material choices for products that are designed to help the future to be more sustainable. These products were developed in a global project that explored the field and subfields of urban mining. This thesis is a part of that project and is meant to come with valuable input to the results. In this urban mining project two products were developed. The two different products that has been developed during this project is the NIX and the UM Factory. They work together with keeping material on the construction site when space is limited in order to reduce the transportation, both for the environmental benefit and also from a cost perspective. Together they will not only keep the material on the site but also refine them so they can be used again. This thesis will look into how these two products can be manufactured and what materials is a suitable choice for the products. These two factors were also thought about during the development of the products, both how to make it as simple design that was easy to produce while still fulfilling the requirements set. Also what materials might be a suitable choice for different parts of the products is considered, in order to be reliable, easy to work with, and relatively cheap. The study also explored some methods and materials that might be worth looking into in a few years. Methods and materials that today are undeveloped or not economically viable.

Context: The data transmission mechanisms in a multi-homed network has gained importance in the past few years because of its potentials. Concurrent multipath transmission (CMT) technique uses the available network interfaces for transmission by pooling multiple paths together. It allows transport mechanisms to work independent of the underlying technology, which resembles the concept of Transport Virtualization (TV). As a result, in the development of Future Internet Architectures (FIA), TV plays a vital role. The leading commercial software technologies like IOS and Android have implemented such mechanisms in their devices. Multipath TCP and CMT-SCTP are the protocols under development which support this feature. The implementation and evaluation of CMT in real-time is complex because of the challenges like path binding, out-of-order packet delivery, packet-reordering and end-to-end delay. Objectives: The main objective of this thesis is to identify the possibilities of implementing CMT in real-time using multiple access technologies, and to evaluate the performance of transmission by measurements and analysis under different scenarios. Methods: To fulfill the objectives of the thesis, different methods are adopted. The development of CMT scenario is based on a spiral methodology where each spiral refers to different objectives. The sub-stages in a spiral are mainly implementation, observations, decisions and modifications. In order to implement and identify the possibilities of CMT in real-time, a deep literature study is performed beforehand. Results: The throughput of data transmission is less affected by varying the total number of TCP connections in transmission. Under different cases it is observed that the throughput has significant impact by varying number of efficient paths in transmission. Conclusion: From the experimental methodology of this work it can be observed that, CMT can be implemented in real-time using off-the-shelf components. Based on the experimentation results, it can be concluded that the throughput of transmission is affected by increasing number of paths. It can also be concluded that the total number of TCP connections during the transmission have less impact on throughput.

The paper is a review of literature on online learning and how it prepares the digital learners into the future work force. Factors contributing to the growth in online education are linked to changing social and economic structures. The College Board Commission on Access, Admissions and Success issued a call for 55% of America’s youth to obtain a postsecondary education credential by 2025 (Bonk, 2015). This is to support and strengthen the position of the United States to be more competitive in a global economy (Burnette & Conley, 2011). There are current questions about student success, open education, informal learning, online plagiarism and principally whether online learning successfully prepare the online student for the future work skills. Keywords: online learning, workforce, digital learners, future jobs

This dissertation examines what motivates individuals to prefer certain types of product attributes over others. It is proposed that consumer preference regarding product attributes is fundamentally connected to an individual’s future orientation, i.e., how a person perceives, thinks about, and copes with time left in life. Specifically, it is posited that future orientations play key roles in shaping a person’s criteria in product evaluation. Thus, this dissertation seeks to integrate the study of future orientation with research on socio-emotional selectivity influences on consumption. Building on past research, this study proposes a conceptual model including four constructs: future orientations, chronological age, product evaluation, and preferences. An experimental study was used to investigate the research objectives and calibrate and validate the model. The experiment examines the moderating effect of future orientations and chronological age on consumer preference for hedonic vs. utilitarian attributes. The subjects were randomly assigned to one of two future orientations (expansive and limited) and one of two attributes contexts (hedonic and utilitarian). The sample for this study was drawn from consumers in Metropolitan Atlanta, Georgia. The research results will lead to an improved understanding of how preference varies from individual to individual and changes over time. In particular the research will provide insights about the impact of an individual’s future orientation on product attitude. The findings will advance current theory in both the new product evaluation and preference literature and have implications for the practice of marketing at levels of marketing strategy, product development, integrated marketing communications and loyalty programs.

Šis darbas skirtas išsiaiškinti jaunų žmonių poreikius bei siekius, pagrindinius sprendimų dėl ateities motyvus bei veiksnius, susijusius su šiais sprendimais. Pagrindinis šio darbo tyrimo tikslas buvo - išsiaiškinti jaunų žmonių ateities orientacijų turinį bei jį lemiančius veiksnius, nustatyti kokią įtaką tam daro ekonominė padėtis, šeimos situacija, pasiekimai mokykloje bei asmeninės savybės ir palyginti didmiesčio bei miestelio mokinių ateities orientacijas. Tyrimo metu buvo apklausti 68 Vilniaus Viršuliškių vidurinės mokyklos bei Giedraičių Antano Jaroševičiaus vidurinės mokyklos 11 – 12 klasių mokiniai. Tyrimas buvo atliekamas anketavimo būdu. Mokiniams buvo pateiktos anoniminės anketos su 31 klausimu Išanalizavus gautus rezultatus, padarytos tokios darbo išvados: 1) Jauni žmonės yra optimistiškai nusiteikę savo tolimesnės ateities atžvilgiu, tiki jog pavyks susikurti sau gerovę: daugiau nei pusė apklaustųjų tikisi, kad ateityje turės ir aukštojo mokslo diplomą, ir sutuoktinį, ir dirbs mėgstamą, gerai apmokamą darbą, ir turės automobilį, jausis pasitikintys savimi bei bus pasiekę dabar užsibrėžtus tikslus. 2) Didžioji dalis jaunų žmonių iš karto po mokyklos baigimo planuoja toliau tęsti mokslus Lietuvoje, mažiau nei puse – palikti savo gimtąjį miestą, trečdalis pradėti dirbti ir tik nedidelė dalis – išvykti dirbti ar mokytis į užsienį. 3) Pagrindinis motyvas palikti savo gimtąjį miestą – išsilavinimo siekimas; tęsti mokslus Lietuvoje – noras ateityje susirasti gerai...

The current Internet routing and addressing architecture is facing a serious scalability problem. The default free zone (DFZ) routing table size grows at an increasing and potentially alarming rate. The Internet architecture uses a single namespace - the IP address, to express two functions about a network entity: its identifier and locator. This overloading of semantics leads to the scalability problem as a consequence of multihoming, traffic engineering, and nonaggregatable address allocations. The current Internet architecture does not inherently support emerging features such as mobility either. This thesis presents a simple addressing and forwarding architecture (SAFA) for the Internet. SAFA separates the locator namespace from the ID namespace so that the locators can follow the hierarchies in the Internet topology and be aggregated. The locators are allocated dynamically and automatically. The hierarchical format of locators gives end systems more control over the route selection. A straightforward forwarding scheme is designed based on the hierarchical addressing scheme. The meshed part of the Internet topology is integrated into the forwarding procedure through a special forwarding table. With a rendezvous service that maps from IDs to locators, SAFA also provides scalable support for mobility, multihoming and traffic engineering. Our work also includes an Internet topology study and a prototype implementation of the architecture. The evaluation results suggest that SAFA would be feasible in the current Internet if deployed.
