Abstract

Over the last decade, various nanomaterials (NMs) have attracted tremendous attention with the incredible development in nanoscience and nanotechnology. Some NMs are explored increasingly for biomedical applications, including drug delivery carriers, imaging probes, antimicrobial agents, biosensors, and tissue engineering scaffolds. However, the in vitro and in vivo toxicities of NMs related to oxidative stress are the main obstacles to use them in biomedical fields. One of the most promising strategies to address these obstacles is functionalizing NMs with biocompatible molecules or materials. In this Special Issue, we are especially interested in manuscripts that advance the understanding of the interaction of NMs with cells, such as cellular responses to NMs, intracellular behaviors of NMs, therapeutic and imaging potentials of NMs, as well as the functionalization of NMs through coating, patterning and hybridization with other biomolecules for multifaceted biomedical applications.

Abstract

Shape memory alloys (SMAs) have special property of the shape memory effect. After thermal treatment above the martensitic transition temperature, the alloys come back to the original shape when the alloys heat again after having cooled it to the temperature that is lower than the martensitic transition temperature. By means of this property, many industrial parts and systems were produced. This Special Issue "Shape Memory Alloys 2017" is constructed articles reporting new and progressive research results, as well as reviews of particular classes of fundamental physics of the materials and their applications of SMAs. Through its 17 efficient articles, the reader will approach to researches related to SMAs with their peculiar magnetic, thermo-mechanical properties, superelasticity, plastic deformation and compression under pressure. These physical properties introduce a large number of applications as faster SMA actuators, application of medical devices, industrial joining parts, volts, and magnetic/mechanical/thermal sensors. These articles are intended scientific researchers, professional engineers, students to obtain a better understanding in this field lately.

Abstract

Dear Colleagues,The assembly of organic ligands and metal centres yields coordination polymers, many of which find applications in conductivity, catalysis, magnetism, gas sorption, biological sensing and luminescence. The structure and topology of coordination polymers may be manipulated by changing the reaction conditions, leading to a large variety of structurally and topologically unique products. However, controlling and predicting the final outcome of the self-assembly procedure remains one of the major challenges in the field. The final products are often strongly influenced by factors such as the behaviour of a functional group in a molecule, the influence of the crystallization conditions and the various conformations of the components within the crystal.This Special Issue aims to cover a broad range of subjects in coordination polymer chemistry, which are important to the continued growth of the field, showcase current developments and realise its full potential in applications to address major societal challenges.Therefore, we invite you to contribute a research article to this Special Issue and provide a clear snapshot of your research in this field.

Abstract

Heat exchange processes in steady flows have been studied extensively over the last two hundred years, and are now a part of undergraduate syllabi in most engineering courses. However, heat transfer processes in oscillatory flow conditions are still not very well understood. Their importance is well recognized in applications including Stirling machines, thermoacoustic engines, and refrigerators or pulsed-tube coolers in cryogenics. Additionally, the enhancement of heat transfer by using oscillatory, and, in some cases, pulsating flows is important in many areas of mechanical and chemical engineering for the intensification of heat transfer processes and possible miniaturization of heat exchangers of the future.This Special Issue was intended as a dissemination platform for researchers working in the field to have an opportunity to consolidate recent advances in this important research area. All types of research approaches were invited, including experimental, theoretical, computational fluid dynamics (CFD), and their combinations, while the approaches could be either of a fundamental or applied nature. The guest editor and the editorial team of Applied Sciences hope that the readership will find the selection of ten articles presented here a useful contribution to the emerging field of heat transfer processes in oscillatory flow conditions.

Abstract

MEMS mirrors can steer, modulate and switch light, as well as control the wavefront for focusing or phase modulation. MEMS mirrors have found enormous commercial success in projectors, displays and fiberoptic communications. Micro-spectrometers based on MEMS mirrors are starting to appear in the consumer market. There are also many breakthroughs in applying MEMS mirrors for endoscopic imaging. Equally excitingly, a new wave of opportunities for MEMS mirrors is coming up, for example, micro-LiDAR for autonomous driving and robotics, optical cross connect (OXC) for cloud data centers, and optical scanners for virtual reality/augumented reality, just to name a few. Of course, there are a number of big challenges that researchers and engineers must overcome to fully utiltize MEMS mirrors’ potential: modeling and control are inherently complex due to the multiphysics, multi-DOF and nonlinear nature of the microactuators for MEMS mirrors; reliability is always a huge hurdle for commercilization; and the tradeoffs among the speed, aperture, and scan range are often overwhelming. Accordingly, this Special Issue seeks to showcase research papers, short communications, and review articles that focus on: (1) novel designs, fabrication, control, and modeling of MEMS mirrors based on all kinds of actuation mechanisms; and (2) new developments of applying MEMS mirrors of any kind in consumer electronics, optical communications, industry, medicine, agriculture, space, or defense.

Abstract

ca. 200 words; this text will present the book in all promotional forms (e.g. flyers). Please describe the book in straightforward and consumer-friendly terms.[enter Summary/Description]Based on information theory, a number of entropy measures have been proposed since the 1990s to assess systems’ irregularity, such as approximate entropy, sample entropy, permutation entropy, intrinsic mode entropy, and dispersion entropy, to cite only a few. Among them, sample entropy has been used in a very large variety of disciplines for both univariate and multivariate data. However, improvements to the sample entropy algorithm are still being proposed because sample entropy is unstable for short time series, may be sensitive to parameter values, and can be too time-consuming for long data. At the same time, it is worth noting that sample entropy does not take into account the multiple temporal scales inherent in complex systems. It is maximized for completely random processes and is used only to quantify the irregularity of signals on a single scale. This is why analyses of irregularity—with sample entropy or its derivatives—at multiple time scales have been proposed to assess systems’ complexity. This Book presents contributions related to new and original research based on the use of sample entropy or its derivatives.

Abstract

The book deals with product recommendations generated by information systems referred to as recommender systems. Recommender systems assist consumers in making product choices by providing recommendations of the range of products and services offered in an online purchase environment. The quantitative research study investigates the influence of psychographic and sociodemographic determinants on the interest of consumers in personalized online book recommendations. The author presents new findings regarding the interest in recommendations, importance of product reviews for the decision process, motives for submitting ratings as well as comments, and the delivery of recommendations. The results show that opinion seeking, opinion leading, domain specific innovativeness, online shopping experience, and age are important factors in respect of the interest in personalized recommendations.

Abstract

research agenda for e-Government. When e-Government was first conceived, it was designed upon basic technologies where the emphasis was only on the simple display of government information for citizens to read. Nowadays, e-Government design comprises many complicated modules such as upload and download consoles, two-way interaction consoles between citizens and government agents, integrated government business processes presenting the whole of government, and it does not depend solely on technology. The complexity of e-Government has now evolved to include political, cultural, economic, social and technical dimensions. Bringing all these difficult aspects together is so complicated that it needs carefully planned strategies informed by local contextual characteristics. Rather than giving formulaic definitions and conceptual standpoints on many aspects of e-Government, as is the case in many e-Government publications, this book will explore the frontiers of global knowledge value chains by discussing current and future dimensions of e-Government. For example, the book discusses the concept of data governance by exploring how actual opening up of government data can be achieved, especially in a developing world context. Further, the book posits that opening government data should be followed by the opening up of government business processes in order to peddle the concept of accountability and responsiveness. Much text on data governance has concentrated on articulating the basic definitions surrounding this concept. Another very important topic explored in this book is regarding how the concept of decolonisation can be extended to e-Government by providing practical examples as to how researchers in the developing world can contribute to the advancement of e-Government as a scientific field of enquiry and guide its implementation, thereof. Decolonisation is advocated for in e-Government research so that there is a balance in the inclusion of the Afrocentric knowledge into e-Government advancement other than over-reliance on the Euro-, Asia- and America-centric knowledge value chains (Mbembe 2015). As e-Government is a very expensive undertaking, the issue of funding has excluded African countries and a majority of the developing world from implementing e-Government. Despite funding being a critical cornerstone of e-Government development, there is a dearth of information on this topic. Therefore, this book provides a chapter which discusses traditional and innovative ways of funding e-Government design and implementation which can go a long way in improving e-Government penetration into the developing world. Further, the book explores how intelligent e-Government applications can be designed, especially in resource-constrained countries. A couple of emerging technology innovations such as fog computing and intelligent information technology are explored within the realm of e-Government design.

Abstract

One of the main reasons to name this book as Financial Management from an Emerging Market Perspective is to show the main differences of financial theory and practice in emerging markets other than the developed ones. Our many years of learning, teaching, and consulting experience have taught us that the theory of finance differs in developed and emerging markets. It is a well-known fact that emerging markets do not always share the same financial management problems with the developed ones. This book intends to show these differences, which could be traced to several characteristics unique to emerging markets, and these unique characteristics could generate a different view of finance theory in a different manner. As a consequence, different financial decisions, arrangements, institutions, and practices may evolve in emerging markets over time. The purpose of this book is to provide practitioners and academicians with a working knowledge of the different financial management applications and their use in an emerging market setting. Six main topics regarding the financial management applications in emerging markets are covered, and the context of these topics are ""Capital Structure,"" ""Market Efficiency and Market Models,"" ""Merger and Acquisitions and Corporate Governance,"" ""Working Capital Management,"" ""Financial Economics and Digital Currency,"" and ""Real Estate and Health Finance.""
