A Framework of Cloud and AI based Intelligent Hotel
In the past 10 years, the hospitality industry\u27s discussions on cloud technology have been ongoing to rise, but they had been stuck in the stage of paper talks, and there were no substantive action. In view of the huge potential of the intelligent hospitality industry market, and the related academic research literatures about the virtualized cloud architecture, AI technology application and intelligent virtual housekeeper system among in this industry is still relatively few. Therefore, I selected the industry success case led by Taiwan\u27s Ministry of Science and Technology as a case study for this research, besides, quantified the system\u27s trial operation phase, relevant operational performance results, as the focus of this intelligent hotel case implementation effectiveness evaluation
Constructing the Smart Hotel Architecture – A Case Study in Taiwan
A smart hotel is an intelligent hotel with a range of information technologies working together to let the customers have an honorable and convenient vacation environment. It allows customers to have a profound image about not only the hotel, but also the city and the country. Furthermore, it can increase the customer loyalty and repurchase rate as well. Thus, developing a smart hotel is critical for the hospitality industry in practice. This research presents a case study of a new five star intelligent hotel- Fleur de Chine Hotel at Sun Moon Lake in Taiwan. It describes how they built their digital hotel and virtual housekeeper service platform. Through the networked facilities and integrated information systems, people could get relevant information easily and efficiently. In addition, this smart system could provide hotel customers with the housekeeper service similar to a very important person (VIP) room or a presidential suite
Stationary Light Pulses in Cold Atomic Media
Stationary light pulses (SLPs), i.e., light pulses without motion, are formed
via the retrieval of stored probe pulses with two counter-propagating coupling
fields. We show that there exist non-negligible hybrid Raman excitations in
media of cold atoms that prohibit the SLP formation. We experimentally
demonstrate a method to suppress these Raman excitations and realize SLPs in
laser-cooled atoms. Our work opens the way to SLP studies in cold as well as in
stationary atoms and provides a new avenue to low-light-level nonlinear optics.Comment: 4 pages, 4 figure
Controlled Heterogeneous Nucleation and Growth of Germanium Quantum Dots on Nanopatterned Silicon Dioxide and Silicon Nitride Substrates
Controlled heterogeneous nucleation and growth of Ge quantum dots (QDs) are demonstrated on SiO_2/Si_3N_4 substrates by means of a novel fabrication process of thermally oxidizing nanopatterned SiGe layers. The otherwise random self-assembly process for QDs is shown to be strongly influenced by the nanopatterning in determining both the location and size of the QDs. Ostwald ripening processes are observed under further annealing at the oxidation temperature. Both nanopattern oxidation and Ostwald ripening offer additional mechanisms for lithography for controlling the size and placement of the QDs
High-Mobility Pentacene-Based Thin-Film Transistors With a Solution-Processed Barium Titanate Insulator
Abstract—Pentacene-based organic thin-film transistors
(OTFTs) with solution-processed barium titanate (Ba1.2Ti0.8O3)
as a gate insulator are demonstrated. The electrical properties
of pentacene-based TFTs show a high field-effect mobility of
8.85 cm2 · V−1 · s−1, a low threshold voltage of −1.89 V, and a
low subthreshold slope swing of 310 mV/decade. The chemical
composition and binding energy of solution-processed barium
titanate thin films are analyzed through X-ray photoelectron
spectroscopy. The matching surface energy on the surface of
the barium titanate thin film is 43.12 mJ · m−2, which leads to
Stranski–Krastanov mode growth, and thus, high mobility is
exhibited in pentacene-based TFTs.

SiGeo: Sub-One-Shot NAS via Information Theory and Geometry of Loss Landscape
Neural Architecture Search (NAS) has become a widely used tool for automating
neural network design. While one-shot NAS methods have successfully reduced
computational requirements, they often require extensive training. On the other
hand, zero-shot NAS utilizes training-free proxies to evaluate a candidate
architecture's test performance but has two limitations: (1) inability to use
the information gained as a network improves with training and (2) unreliable
performance, particularly in complex domains like RecSys, due to the
multi-modal data inputs and complex architecture configurations. To synthesize
the benefits of both methods, we introduce a "sub-one-shot" paradigm that
serves as a bridge between zero-shot and one-shot NAS. In sub-one-shot NAS, the
supernet is trained using only a small subset of the training data, a phase we
refer to as "warm-up." Within this framework, we present SiGeo, a proxy founded
on a novel theoretical framework that connects the supernet warm-up with the
efficacy of the proxy. Extensive experiments have shown that SiGeo, with the
benefit of warm-up, consistently outperforms state-of-the-art NAS proxies on
various established NAS benchmarks. When a supernet is warmed up, it can
achieve comparable performance to weight-sharing one-shot NAS methods, but with
a significant reduction (\%) in computational costs.Comment: 24 pages, 7 figure
