    The global tourism industry has seen a rapid development for the last ten years, both eco-tourism and educational tourism has been, and still is, big parts in this. Museums has played the key role as the core of cultural production, creating and interpreting places where the universe is realized, understand and mediated (Fife as cited in Ramshaw, 2006, p.46). This thesis will focus on tourists' experience at Hurtigrutemuseet in Stokmarknes, based on tourists' perception and service evaluation of the museum (before, during, and after the visit). Tourists’ satisfaction has been generally used as an assessment tool for the evaluation of travel experiences, products and services offered at the destination (Bramwell, 1998; Ross & Iso Ahola, 1991). This gives researchers a navigation that in this study tourist’s experience is be examined by tourist’s satisfaction measurement. The aim of this study case is to understand how the performance of the provider (Hurtigrutemuseet) can impact tourists' experience. The economic aspect in this is not a part of this study case and will be disregarded throughout the paper

    Liquid Metal-Based Tunable Linear Phase Shifters With Low Insertion Loss, High Phase Resolution, and Low Dispersion

    A linear, tunable, and self-compensating phase shifter based on liquid metal (LM) is proposed in this article using a half-mode substrate-integrated waveguide (HMSIW). The key phase shifting element is a via-pad-slot (VPS) structure where a thru via is attached to a pad surrounded by an annular slot. This is equivalent to a shunt capacitance and inductance loaded on the HMSIW. Phase shift is achieved when the annular slot is covered by the LM that runs in microfluidic channels on the surface of the HMSIW. This allows easy implementation and convenient manipulation of the LM without incurring excessive losses. A self-compensation structure, based on multiple rows of VPSs, is proposed to achieve a low phase deviation with frequency (low dispersion). The design method to ensure a linear and small phase step over a large phase range is presented. Two phase shifters have been designed and experimentally verified. Phase shifter-I, with two VPS rows, provides a phase shift from 0&lt;inline-formula&gt; &lt;tex-math notation="LaTeX"&gt;∘^{\circ}&lt;/tex-math&gt; &lt;/inline-formula&gt; to 41&lt;inline-formula&gt; &lt;tex-math notation="LaTeX"&gt;∘^{\circ}&lt;/tex-math&gt; &lt;/inline-formula&gt; with &lt;inline-formula&gt; &lt;tex-math notation="LaTeX"&gt;±\pm&lt;/tex-math&gt; &lt;/inline-formula&gt;1&lt;inline-formula&gt; &lt;tex-math notation="LaTeX"&gt;∘^{\circ}&lt;/tex-math&gt; &lt;/inline-formula&gt; phase deviation with frequency over 9.5&amp;#x2013;12.5 GHz. The average phase resolution is 1&lt;inline-formula&gt; &lt;tex-math notation="LaTeX"&gt;∘^{\circ}&lt;/tex-math&gt; &lt;/inline-formula&gt;. The measured insertion loss (IL) is 0.8 &lt;inline-formula&gt; &lt;tex-math notation="LaTeX"&gt;±\pm&lt;/tex-math&gt; &lt;/inline-formula&gt; 0.1 dB, with a figure of merit of 45.6&lt;inline-formula&gt; &lt;tex-math notation="LaTeX"&gt;∘^{\circ}&lt;/tex-math&gt; &lt;/inline-formula&gt;/dB. Phase shifter-II uses three VPS rows to provide a phase shift from 0&lt;inline-formula&gt; &lt;tex-math notation="LaTeX"&gt;∘^{\circ}&lt;/tex-math&gt; &lt;/inline-formula&gt; to 180&lt;inline-formula&gt; &lt;tex-math notation="LaTeX"&gt;∘^{\circ}&lt;/tex-math&gt; &lt;/inline-formula&gt; with a phase resolution of 1.68&lt;inline-formula&gt; &lt;tex-math notation="LaTeX"&gt;∘^{\circ}&lt;/tex-math&gt; &lt;/inline-formula&gt;. The achieved phase deviation with frequency is within &lt;inline-formula&gt; &lt;tex-math notation="LaTeX"&gt;±\pm&lt;/tex-math&gt; &lt;/inline-formula&gt;2&lt;inline-formula&gt; &lt;tex-math notation="LaTeX"&gt;∘^{\circ}\mathbf{}&lt;/tex-math&gt; &lt;/inline-formula&gt; over 10&amp;#x2013;12.5 GHz and within &lt;inline-formula&gt; &lt;tex-math notation="LaTeX"&gt;±\pm&lt;/tex-math&gt; &lt;/inline-formula&gt;5&lt;inline-formula&gt; &lt;tex-math notation="LaTeX"&gt;∘^{\circ}&lt;/tex-math&gt; &lt;/inline-formula&gt; over 9&amp;#x2013;13 GHz. The measured IL is 1.1 &lt;inline-formula&gt; &lt;tex-math notation="LaTeX"&gt;±\pm&lt;/tex-math&gt; &lt;/inline-formula&gt; 0.1 dB with a competitively high figure of merit of 163.6&lt;inline-formula&gt; &lt;tex-math notation="LaTeX"&gt;∘^{\circ}&lt;/tex-math&gt; &lt;/inline-formula&gt;/dB. Unlike many other phase shifters, the loss of the proposed phase shifters does not increase with the phase shift. The measurements are in very good agreement with the circuit analysis and simulations. The proposed linear phase shifter has demonstrated high performance and very attractive features such as low IL that does not strongly depend on the phase shift, linear phase change, high phase resolution, and low phase dispersion with frequency. Compared with other LM-enabled phase shifters, it has the advantage of easy implementation and control. This LM-based phase shifter also potentially has high power handling capability.</p
