    Beschreibung: Global population growth, exposure to climate-driven risks, continuous ongoing economic crises, persistent levels of poverty, migration phenomena, exponential increase in the use of digital technology and consequent digital divide, and the urgent demand for more equal spaces are amongst the major drivers of change within the housing sector. This book seeks to envision some of the future housing scenarios, outlining a series of possible transformations that will affect the global housing models in the coming years. The essays in the book are not intended to provide predictions on housing, but rather to try to grasp how social attitudes, economic values, and technologies employed are changing. The issues addressed range from exploring the potential of green and digital strategies both in regenerating existing building heritage and in new construction within developing countries to addressing the humanitarian challenges of climate change and mitigating social inequality.

    Beschreibung: A Schiff base (imine -N=CH-) is a part of a popular group of organic compounds prepared form primary amines and aldehyde. Many studies have been carried out on Schiff bases not only as organic compounds but also as ligands for metal complexes. In this context, this book provides a comprehensive, interdisciplinary review of Schiff base compounds, with an emphasis on the latest advances. It compiles research results, commentary, reviews, and more dealing with preparation, spectroscopy, crystallography, (asymmetric) synthetic roles, physical properties (magnets, optics, etc.), computational chemistry, and theoretical chemistry. The book focuses on Schiff base and its strong connection to organic chemistry, biochemistry, and polymer materials chemistry. It covers three topics: Schiff base of organic chemistry, Schiff base of inorganic chemistry, and Schiff base of functional or biological materials.

    Beschreibung: The palm oil industry is one of the oldest and most established commercial industries in the world. The product is hailed as an economically viable crop as compared with other oils used and consumed globally. This book provides an overview of the palm oil industry and the management of the crop itself. There has always been a growing interest in the scientific community to better understand this crop as well as the related industrial processes for environmental and nutritive purposes. As such, this book presents useful information on the palm oil industry from multiple perspectives.

    Beschreibung: The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has probably been the most important disease to emerge in the 21st century. This viral zoonotic disease has been a significant cause of morbidity and mortality worldwide, but with a higher impact in low- and middle-income countries of Africa, Asia, and Latin America. Up to December 4, 2022, more than 645,195,564 cases had been reported globally, with 6,640,845 deaths, and more than 13,054,668,703 doses of a vaccine had been given. Research has been of the utmost importance in the COVID-19 crisis: a great deal of knowledge was gathered between December 2019 and December 2022. Appropriate evidence-based management and the development of safe and effective vaccines have been key to controlling the virus. This book presents a selection of the last two years’ learning from research and clinical practice concerning SARS-CoV-2/COVID-19.

    Beschreibung: Crystal growth is the process of arranging atoms, ions, molecules, or molecular assemblies into regular three-dimensional periodic lattices. There are different synthesis and crystal growth methods depending on the material available, such as evaporative synthesis, hydrothermal method, and solid-state reaction. Crystal growth technology has various applications, including in the production of semiconductor devices, solar cells, and optical components. In this book, we deal with some crystalline materials synthesized by different methods, their crystal growth in relation to their physical properties or biological activities, and their applications, in particular in biology, medicine, and semiconductors.

    Notizen: Abstract If the sequence of functions ϕj, k is a wavelet frame (Riesz basis) or Gabor frame (Riesz basis), we obtain its perturbation system ψj,k which is still a frame (Riesz basis) under very mild conditions. For example, we do not need to know that the support of ϕ or ψ $$(\hat \phi or\hat \psi )$$ is compact as in [14]. We also discuss the stability of irregular sampling problems. In order to arrive at some of our results, we set up a general multivariate version of Littlewood-Paley type inequality which was originally considered by Lemarié and Meyer [17], then by Chui and Shi [9], and Long [16].

    Thema: Elektrotechnik, Elektronik, Nachrichtentechnik
    Notizen: Abstract The stability of time-varying autoregressive (AR) models is an important issue in such applications as time-varying spectrum estimation and electroencephalography simulation and estimation. In some cases, such as time-varying spectrum estimation, the models that exhibit roots near unit moduli are difficult to use. Thus a tighter stability condition such as stability with a positive margin is needed. A time-varying AR model is stable with a positive margin if the moduli of the roots of the time-varying characteristic polynomial are somewhat less than unity for every time instant. Recently, a new method for the estimation of the time-varying AR models was introduced. This method is based on the interpretation of the underdetermined time-varying prediction equations as an ill-posed inverse problem that is solved by Tikhonov regularization. The method is referred to as the deterministic regression smoothness priors (DRSP) scheme. In this paper, a stabilization method in which the DRSP scheme is augmented with nonlinear stability constrainst is proposed. The problem is formulated so that stability with a positive margin can also be achieved. The problem is solved iteratively with an exterior point algorithm. The performance of the algorithm is studied with a simulation. It is shown that the proposed approach is well suited to stable modeling of signals containing narrowband transitions.

    Notizen: Abstract In this paper, the general class of singular systems with delay and linear constant coefficient singular systems with delay are discussed. First, several definitions of stability are presented for singular systems with delay, and general sufficient stability conditions and instability conditions are obtained. Second, stability and instability are analyzed for linear constant coefficient singular systems with delay.
