This thesis presents a study of impedance optimisation of active microstrip patch antennas to multiple frequency points. A single layered aperture coupled microstrip patch antenna has been optimised to match the source reflection coefficient of a transistor in designing an active antenna. The active aperture coupled microstrip patch antenna was optimised to satisfy Global Positioning System (GPS) frequency specifications.

This dissertation is composed of two parts, an integrative essay and a set of published papers. The essay and the collection of papers are placed in the context of development and application of time series econometric models in a temporal-axis from 1970s through 2005, with particular focus in the Marketing discipline. The main aim of the integrative essay is on modelling the effects of marketing actions on performance variables, such as sales and market share in competitive markets.

This study was an attempt to investigate the possible effects of integrating MI-based activities into developing the EFL students’ speaking skills, and then to find out the students’ evaluation of such an integration of MI-based activities. Therefore, to attain those two main objectives, the mixed research method was adopted: the quantitative approach utilizing a quasi-experimental study in which MI-based activities were integrated into an experiment.

This paper presents a Bayesian approach based on integral experiments to create correlations which do not appear with differential data. Some quantities such as the fission cross section (s), neutron multiplicity (n¯p), neutron spectra (x), etc. are usually neither modeled together nor measured in coincidence, thus there is no correlation matrices in evaluated nuclear data libraries.

The green growth prediction plays an important role to assess and monitor the growth rate of a local region. Managers and researchers can make timely adaptation policy to improve and innovate economic, cultural and environmental performance to impulse the green growth. The study used the methods such as the multiple criteria analysis, analytic hierarchy process, principal component analysis, and the grey theory model to build and integrate green growth indicators into the green growth index.

Like paper-based signatures, digital signatures intend to respect a number of security assumptions. Methods of digital signature apposed by a single user have been defined and are widely used. But is it sufficient? What if a legal document requires witnesses and notarization, or a contract needs the signatures of several officers?This paper will first show the basics to understand digital signatures and how the a security properties of integrity, authentication, and non-repudiation are respected.

Behavioral arousal requires integration of multiple neurotransmitter and neuromodulatory systems. Identifying these systems is the key to not only a better understanding of the neurobiology of sleep⁄wakefulness but may also lead to the discovery of potential therapeutic targets for various sleep disorders.

Methionine (Met) is an essential amino acid and the only sub-strate for synthesis of S-adenosylmethionine (AdoMet) that is the main substrate for multiple intracellular methylases. There are two modes of Met metabolism in liver. In case of its dietary restriction Met can be metabolized via conservative remethylation cycle. In case of Met excess (high [Met]) it is mostly converted to cysteine via transsulfuration pathway.

CD98 heavy chain (CD98hc), expressed at high levels in developing human trophoblasts, is an integral membrane protein with multiple N-linked gly-cosylation sites and known to be important for cell fusion, adhesion, and amino acid transport. Western blotting and flow cytometry were used to study the effect of brefeldin A, an inhibitor of protein translocation through the Golgi, on CD98hc in the human placental trophoblast cell line BeWo.

Continuous integration is the practice where the work of all the developers are integrated, analyzed and verified on a regular basis, preferably multiple times a day. It takes the latest situation from the source control system, performs unit tests, makes a build, deploys the application, performs integration tests and creates reports about these steps and communicates them with the team, all automatically without human interaction.
