Impact of Airbnb on customers' behaviour in the UK hotel industry

Airbnb is one of the sectors of the sharing economy that is disrupting the hotel industries. In order to find approaches for hotels to mitigate the threat from Airbnb, this research will focus on the major elements influencing customers to choose Airbnb and the issues for the future of the hotel industry. Previous studies have looked at how Airbnb influences customer behaviour, and the impact of Airbnb on the hotel industry, but so far no study has been conducted focusing on the impact of Airbnb on the UK hotel industry. Therefore the purpose of this research is to evaluate the impact of Airbnb on customers’ behaviour within the UK hotel industry in order to determine how the hotel sectors can mitigate the threats posed by Airbnb. This paper highlights managerial and industrial implications

Topologically non-trivial Floquet band structure in a system undergoing photonic transitions in the ultra-strong coupling regime

We consider a system of dynamically-modulated photonic resonator lattice undergoing photonic transition, and show that in the ultra-strong coupling regime such a lattice can exhibit non-trivial topological properties, including topologically non-trivial band gaps, and the associated topologically-robust one-way edge states. Compared with the same system operating in the regime where the rotating wave approximation is valid, operating the system in the ultra-strong coupling regime results in one-way edge modes that has a larger bandwidth, and is less susceptible to loss. Also, in the ultra-strong coupling regime, the system undergoes a topological insulator-to-metal phase transition as one varies the modulation strength. This phase transition has no counter part in systems satisfying the rotating wave approximation, and its nature is directly related to the non-trivial topology of the quasi-energy space

Synthetic gauge potential and effective magnetic field in a Raman medium undergoing molecular modulation

We theoretically demonstrate non-trivial topological effects for a probe field in a Raman medium undergoing molecular modulation processes. The medium is driven by two non-collinear pump beams. We show that the angle between the pumps is related to an effective gauge potential and an effective magnetic field for the probe field in the synthetic space consisting of a synthetic frequency dimension and a spatial dimension. As a result of such effective magnetic field, the probe field can exhibit topologically-protected one-way edge state in the synthetic space, as well as Landau levels which manifests as suppression of both diffraction and sideband generation. Our work identifies a previously unexplored route towards creating topological photonics effects, and highlights an important connection between topological photonics and nonlinear optics

Quantum correlations and violation of Bell inequality induced by External Field in a two photon radiative cascade

We study the polarization dependent second order correlation of a pair of photons emitted in a four level radiative cascade driven by an external field. It is found that the quantum correlations of the emitted photons, degraded by the energy splitting of the intermediate levels in the radiative cascade can be efficiently revived by a far detuned external field. The physics of this revival is linked to an induced stark shift and the formation of dressed states in the system by the non-resonant external field. Further, we investigated the competition between the effect of the coherent external field and incoherent dephasing of the intermediate levels. We found that the degradation of quantum correlations due to the incoherent dephasing can be content for small dephasing with the external field. We also studied the non-locality of the correlations by evaluating the Bell's inequality in the linear polarization basis for the radiative cascade. We find that the Bell parameter decreases rapidly with increase in the intermediate level energy splitting or incoherent dephasing rate to the extent that there is no violation. However, the presence of an external field leads to control over the degrading mechanisms and preservation of nonlocal correlation among the photons. This in turn can induce, violation of Bell's inequality in the radiative cascade for arbitrary intermediate level splitting and small incoherent dephasing

Monitoring Kereta Api Berbasis GIS

GIS (Geographic Information System) adalah sebuah sistem informasi berbasis pemetaan dan geografi. System ini sering dipakai sebagai monitoring suatu benda, baik yang bergerak maupun tidak, dan banyak yang menggunakan system ini dalam proyek akhir, salah satunya adalah proyek akhir [1], proyek akhir tersebut memiliki kekurangan dibagian peta, pada bagian tersebut tampilan pada peta masih belum lengkap dan juga masih belum bisa menampilkan secara real-tim, oleh karena itu, pada proyek akhir ini dibuat sebuah sistem informasi posisi kereta api berbasis GIS, sistem ini memberikan informasi tentang posisi kereta api secara real-tim , dengan fasilitas lain berupa informasi nama masinis yang sedang bertugas, kecepatan, dan koordinat kereta. Sistem ini juga dilengkapi dengan peringatan kepada masisnis jika ada kereta lain didepanya, peringatanya berupa pesan singkat atau SMS. dengan adanya SMS tersebut diharapkan dapat mengurangi kecelakaan kereta api, Sedangkan pada sisi GIS, posisi kereta api akan ditampilkan kedalam bentuk peta yang diambil dari google map. pada google map terdapat fitur API, API sendiri adalah Application Programming Interface yang mempunyai banyak fitur, salah satunya adalah MAP API, dengan fitur tersebut kita dapat mengakses google map kedalam berbagai aplikasi. Dari hasil pemetaan data koordinat yang dikirimkan oleh kereta. Hasil pemetaan posisi tersebut tepat berada pada rel, dan ada beberapa koordinat yang sedikit menyimpang. Penyimpangan tersebut juga tidak terlalu jauh yaitu sekitar 4-5 meter dari titik sebenarnya. Kata kunci : GIS, kereta api, Monitoring
