Master thesis does quality matter (in emerging countries)? a cross-country analysis of different quality-based trading strategies and the evaluation of the price of quality with a focus on emerging markets.
No full textMasteroppgave(MSc) in Master of Science in Finance - Handelshøyskolen BI, 2019Given the theoretical foundation, as well as empirical support from previous studies,
especially by Asness, Frazzini and Pedersen (2019), this research examines the effect
of firm quality on scaled prices. The research is conducted using a sample of developed
markets, as well as developing markets. The price of quality is significant across
developed and developing markets. The second part of this research establishes a
trading strategy of going long in high-quality firms and shorting low-quality firms. The
strategy yields significant, positive alphas across all countries, but is subject to large tail
risks. Thus, combining this strategy with other factor strategies improves risk-adjusted
returns, and greatly reduces tail risks. The quality factor is found to be more
pronounced in developing markets.

3-D construction of monolithic passive components for RF and microwave ICs using thick-metal surface micromachining technology
No full textAs a viable technological option to address today's strong demands for high-performance monolithic low-cost passive components in RF and microwave integrated circuits (ICs), a new CMOS-compatible versatile thick-metal surface micromachining technology has been developed. This technology enables to build arbitrary three-dimensional (3-D) metal microstructures on standard silicon substrate as post-IC processes at low temperature below 120 degreesC. Using this technology, various highly suspended 3-D microstructures have been successfully demonstrated for RF and microwave IC applications. We have demonstrated spiral inductors suspended 100 mum over the substrate, coplanar waveguides suspended 50 mum over the substrate, and complicated microcoaxial lines, which have 50-mum-suspended center signal lines surrounded by inclined ground shields of 100 mum in height. The microwave performance of the microcoaxial transmission line fabricated on a glass substrate has been evaluated to achieve very low attenuation of 0.03 dB/mm. at 10 GHz with an effective dielectric constant of 1.6. The process variation/manufacturability, mechanical stability, and package issues also have been discussed in detail
Characterization of Ca-Bi-Mo oxide catalyst for propane ammoxidation
No full textThe physicochemical properties of highly active and selective Ca−Bi−Mo oxide for ammoxidation of propane to acrylonitrile were investigated by XRD (powder), IR/Raman, XPS, and TPRX/TPRO (temperature programmed reaction/temperature programmed reoxidation) techniques. It was found that the phases in the Ca−Bi−Mo oxide varied with the composition of the oxide. The modified γ-bismuth molybdate (γ-Bi2MoO6) and defective Ca−Bi−Mo phases produced by addition of Bi oxide played an important role in propane ammoxidation to acrylonitrile. XPS results revealed that the mole ratio of elements on the surface was different from that in the bulk. The concentration of bismuth decreased from the surface to the inner layer of CaxBi12-xMo12 oxide, while the concentration of calcium increased from the surface to the inner layer. The Ca−Bi−Mo oxide showed good catalytic performance when an appropriate amount of calcium oxide was present on the surface along with Bi and Mo oxides. The addition of Ca oxide into Bi−Mo oxide decreased the number of active sites for complete oxidation and increased the ability of reoxidation (O2 consumption) of reduced catalysts

New best solutions to VRPSPD benchmark problems by a perturbation based algorithm
No full textThis paper discusses the vehicle routing problem with simultaneous pickup and delivery (VRPSPD), in which both pickup and delivery tasks simultaneously occur at various customer locations. The objective is to design a set of minimum distance routes with the minimum number of vehicles satisfying all the customers. This paper proposes a heuristic algorithm consisting of a route construction procedure, a route improvement procedure, and a solution perturbation procedure. A new sweep-based route construction method is developed to generate better initial solutions. In the route improvement procedure, a series of inter- and intra-route improvement algorithms are applied. The perturbation procedure perturbs a solution by removing some routes and stops from the solution and reinserting them into the solution. The last procedure is used to escape from local optima. Computational experiments on various benchmark instances are performed to evaluate our algorithm against the previously proposed approaches. New best solutions for many benchmark instances are found.

Impact of large-scale activities on macroscopic fundamental diagram: Field data analysis and modeling
No full textLarge-scale activities always have serious impacts on regional traffic states. It is necessary for traffic planners to investigate the characteristics of network traffic flow under large-scale activities and apply proper management strategies. In this paper, based on the field data in Tianjin, China, the impact of large-scale activities and the corresponding control strategies on regional Macroscopic Fundamental Diagram (MFD) and regional traffic states are analyzed. The study area is divided into the inner area and the outer area. Based on the work of Haddad (2012) on the traffic perimeter control in two-region, a dynamic model is calibrated by the empirical data in Tianjin to study the influences of activities and control strategies. Based on the calibrated model, different control strategies are simulated to investigate the impacts on regional traffic flow. The results show that decreasing the transfer flow from the outer area will alleviate the congestion in the inner area effectively, and increasing the system outflow will reduce the densities of both two areas effectively. When the traffic states are already congested, the real control strategies cannot alleviate the congestion of the regional network effectively. According to the various impacts of different strategies, combined control strategies are proposed to mitigate the adverse impact of large-scale activities on the surrounding area.This work was partially supported by the National Natural Science Foundation of China (Grant No. 71771012, No. 71961137008, No. 72171018, and No. 71931002).

Characterization of Ca-Bi-Mo oxide catalyst for selective propane ammoxidation, using XRD, XPS, TPRX/TPRO, and IR/Raman
No full textThe physicochemical properties of highly active and selective Ca-Bi-Mo oxide for ammoxidation of propane to acrylonitrile were investigated by XRD (powder), IR/Raman, XPS, and TPRX/TPRO (temperature programmed reaction/temperature programmed reoxidation) techniques. It was found that the phases in the Ca-Bi-Mo oxide varied with the composition of the oxide. The modified gamma-bismuth molybdate (gamma-Bi2MoO6) and defective Ca-Bi-Mo phases produced by addition of Bi oxide played an important role in propane ammoxidation to acrylonitrile. XPS results revealed that the mole ratio of elements on the surface was different from that in the bulk. The concentration of bismuth decreased from the surface to the inner layer of CaxTBi2-xMo12 oxide, while the concentration of calcium increased from the surface to the inner layer. The Ca-Bi-Mo oxide showed good catalytic performance when an appropriate amount of calcium oxide was present on the surface along with Bi and Mo oxides. The addition of Ca oxide into Bi-Mo oxide decreased the number of active sites for complete oxidation and increased the ability of reoxidation (O-2 consumption) of reduced catalysts.This research was funded by Tong-Suh

Client-consultant interaction practices: Sources of ingenuity, value creation and strategizing
No full textService providers increasingly choose to interact with their clients. Previous studies show that client’s resources and activities can influence the service provider’s ability to create value, to be creative, and to develop competitive strategies. Yet several gaps can be identified in the literature regarding how these abilities are impacted by client-consultant interaction (c-c-i) practices. The purpose of this doctoral thesis is to explain the service providers’ varying ability to offer highly valuable solutions to their clients’ problems, in terms of the practices through which consultants interact with their clients. The main research questions are;
How do client-consultant interaction practices influence a firm’s ability to offer unique value propositions and deliver ingenious solutions, and how do these practices influence the formation of the firm’s strategy? These questions are answered through four papers. Each paper answers a sub-question.
Paper 1 focuses on the impact of c-c-i practices on the service providers’ ingenuity capabilities. The paper asks how project teams shatter constraints in ill-structured problem-solving situations, and what implications this finding has for the understanding of creative action in organizations. This paper sheds light on the c-c-i practices through which project teams shatter their constraints and create ingenious solutions.
Paper 2 focuses on the creative aspects of c-c-i practices and presents the experiences of service providers who have been successful in capitalizing on the creative resources provided by their clients.
Paper 3 is an inquiry into the relationship between c-c-i practices and the service providers’ ability to offer unique value propositions. The paper provides a model to define and assess value created through c-c-i practices. The findings of this paper show that value creation is maximized through c-c-i practices that provide access to various forms of capital and practice that enable capital exploitation. Unique value offerings can be developed from knowing what c-c-i practices to enact in different circumstances.
Paper 4 focuses on the implications of c-c-i practices for the emergence of new strategies. The findings show that mundane business operations can be the locus of strategizing, and that clients can play a role in emergent strategy formation. Theoretical resources for this research are drawn from literature on practice theory, strategy, organizational creativity, and value creation. An explorative research design is used and qualitative data are gathered from 30 cases through extensive field work. Both in-depth and comparative case analyses are performed
Effective email marketing: an empirical study of the impact of personalized communication on customer engagement and purchase decisions
No full textMasteroppgave(MSc) in Master of Science in Business, Marketing - Handelshøyskolen BI, 2019This study investigates the impact of behavior-based personalization on
customer engagement and purchase behavior in the context of email marketing. For
this purpose, the author reviews and combines the following research streams in the
literature: email marketing, personalization of marketing communication, and
customer engagement.
To answer the research question at hand, the author designs a field study in
collaboration with Kahoot! AS, a fast-growing Norwegian start-up company
operating in the education technology industry. Kahoot!’s game-based learning and
trivia platform is used in multiple settings – school and university classrooms,
business training and presentations, social, cultural, and other events (retrieved
from kahoot.com). By leveraging marketing automation technology, which
Kahoot! uses for the email campaigns’ creation and management, the author sets
up and runs the experiment. Findings of the study provide marketing managers with
useful insights on the effectiveness of behavior-based personalization in the email
marketing context as well as contribute to the ongoing academic discussion about
personalized marketing communication and customer engagement.
The results reveal that email communication has a significant positive effect
on customer engagement irrespective of behavior-based personalization. This
proves that email is an effective marketing communication channel, and it should,
therefore, remain a key part of the digital media mix used by marketers. However,
based on the lack of a significant difference in the effectiveness of personalized and
non-personalized email campaigns, the author recommends focusing more on highquality
generic content and the design of the email messages. Furthermore,
consistent with the viewpoints of researchers in the field, the study confirms that
customer engagement is a significant predictor of customer purchases, leading to
the conclusion that firms should invest in customer engagement marketing
initiatives to ultimately achieve better firm performance
Multiproject "hostile" environments
No full textBacheloroppgave i Prosjektledelse fra Handelshøyskolen BI, 2017This thesis addresses the problems and challenges of working in a multiproject
environment, and what could we do to improve it.
The thesis has been prepared in connection with the program BIK 6512 Project
Management 3, at BI Department of Management and Organization Oslo.
The author has been working as a project manager himself for the organization
described for the last 5 years. I’m a Spanish construction engineer who moved to
Norway 5 years ago with my whole family because of the Spanish economy crisis.
I have several years of experience as project manager in Spanish construction
industries, and now I'm leading offshore projects for a Norwegian O & G
engineering company (IKM dsc Engineering). I would like to remark that I’m
fluent in Norwegian and English, but I can express myself much better in English
even though is not my mother language. Please have this in mind when reading
the thesis, thanks!
This thesis has been basically prepared for my own learning, but I really hope it
can contribute to improve the way we face daily our work in a multiproject
