Design, Integration, and Evaluation of IoT-Based Electrochromic Building Envelopes for Visual Comfort and Energy Efficiency

Electrochromic glazing has been identified as the next-generation high-performance glazing material for building envelopes due to its dynamic properties, which allow the buildings to respond to various climate conditions. IoT technologies have improved the sensing, communication, and interactions of building environmental data. Few studies have been done to synthesize the advancements in EC materials and building IoT technologies for better building performance. The challenge remains in the lack of compatible design and simulation tools, limited understanding of integration, and a paucity of evaluation measures to support the convergence between the EC building envelopes and IoT technologies. This research first explores the existing challenges of using EC building envelopes using secondary data analysis and case studies. An IoT-based EC prototype system is developed to demonstrate the feasibility of IoT and EC integration. Functionalities, reliability, interoperability, and scalability are assessed with comparisons of four alternative building envelope systems. Nation-wide evaluations of EC building performance are conducted to show regional differences and trade-offs of visual comfort and energy efficiency. A machine learning approach is proposed to solve the predictive EC control problem under random weather conditions. The best prediction models achieve 91.08% mean accuracy with the 16-climate-zone data set. The importance of predictive variables is also measured in each climate zone to develop a better understanding of the effectiveness of climatic sensors. Additionally, a simulation study is conducted to investigate the relationships between design factors and EC building performance. An instantaneous daylight measure is developed to support active daylight control with IoT-based EC building envelopes

HIPE-templated oleogels stabilized by protein-polysaccharide : preparation and characterization

The high intake of saturated and trans-fats could pose a chronic threat to human health. During the past decades, some fat alternatives in the form of oleogels have been developed to substitute the use of solid fats in food formulation. Generally, oleogels can be formed using chemically modified organogelators such as ethyl cellulose. In this work, we aimed to produce oleogels via high internal phase emulsion (HIPE, φoil=0.82) templates stabilized using food ingredients, i.e. protein and polysaccharide. The fabrication of HIPEs using a mixture of dispersions of two biopolymers, i.e. sodium caseinate (SC) and alginate (ALG), was optimized by varying the protein: polysaccharide ratios (i.e. 6:1, 8:1, 10:1, 12:1) and the pH (i.e. 5.5, 6.0, 7.0). Dry-heat treatment of the SC:ALG mixture at pH 7.0 was also employed for the preparation of the colloidal dispersions as a comparison to the HIPEs and oleogels stabilized by the mixtures adjusted at different pH values. HIPEs and oleogels exhibited better properties as shown by macrostructure, microstructure, physical stability against coalescence and oiling off, and rheological analysis when the pH value and the ratio of SC:ALG increased. The HIPEs and oleogels stabilized by dry-heat treated SC:ALG mixtures showed comparable results with those stabilized by SC:ALG mixed dispersions at pH 7.0. These results can provide a fundamental insight for future promising application of oleogels in fat-based product formulation

Entanglement criteria and nonlocality for multi-mode continuous variable systems

We demonstrate how to efficiently derive a broad class of inequalities for entanglement detection in multi-mode continuous variable systems. The separability conditions are established from partial transposition (PT) in combination with several distinct necessary conditions for a quantum physical state, which include previously established inequalities as special cases. Remarkably, our method enables us to support Peres' conjecture to its full generality within the framework of Cavalcanti-Foster-Reid-Drummond multipartite Bell inequality [Phys. Rev. Lett. 99}, 210405 (2007)] that the nonlocality necessarily implies negative PT entangled states.Comment: 4 pages, publishe

Three-Dimensional Biorthogonal Divergence-Free and Curl-Free Wavelets with Free-Slip Boundary

This paper deals with the construction of divergence-free and curl-free wavelets on the unit cube, which satisfies the free-slip boundary conditions. First, interval wavelets adapted to our construction are introduced. Then, we provide the biorthogonal divergence-free and curl-free wavelets with free-slip boundary and simple structure, based on the characterization of corresponding spaces. Moreover, the bases are also stable

Noise and deviation effects in a bichromatic Raman white light cavity

We analyze the effects of noise and parameter deviations in a bichromatic Raman type white light cavity, with potential applications in precision measurements such as gravitational wave detection. The results show that the dispersion variation induced by parameter deviation can be controlled within $10^{-4}$. The laser phase noise decreases the dispersion magnitude while the amplitude noise increases it. Although we can always adjust the parameters to satisfy the white light condition, both noises make the cavity transmission curve uneven.Comment: 5 pages, 3 figure

Market integration in China

Over the last three decades, China's product, labor, and capital markets have become gradually more integrated within its borders, although integration has been significantly slower for capital markets. There remains a significant urban-rural divide, and Chinese cities tend to be under-sized by international standards. China has also integrated globally, initially through the Special Economic Zones on the coast as launching grounds to connect with world markets, and subsequently through the accession to the World Trade Organization. For future policy considerations, this paper argues that its economic production needs to be spatially concentrated, and its social services need to be spread out to the interior to ensure harmonious development and domestic integration (through inclusive rural-urban transformations and effective territorial development).Economic Theory&Research,Banks&Banking Reform,Debt Markets,Emerging Markets,Access to Finance
