This study presents an analysis of two aesthetic properties, complexity and diversity, in Palladian architecture. The former highlights the fractal dimension of façade geometry, and the latter its semantic randomness. Along with a methodological description and advice on settings, this study contributes to the discussion about mathematical beauty in architecture. |
Food Studies aims to help readers understand and address numerous issues within food, food culture, and food systems. These subjects transcend disciplinary boundaries and call attention to how matter, meaning, and movement produce complex and dynamic food-human realities. Chapters range from sovereignty to breastfeeding, financialization to food porn, pollination to fair trade. Embedded throughout, art, poetry, illustration, and audiovisual works offer moments to reflect on and synthesize the text-based entries. Through reading, classroom discussion, and engaging with the extensive pedagogical tools, learners and teachers alike may acquire a new sense of things foodish—along with a new sense of their own place and role within food systems themselves. |
This book presents computer programming as a key method for solving mathematical problems. There are two versions of the book, one for MATLAB and one for Python. The book was inspired by the Springer book TCSE 6: A Primer on Scientific Programming with Python (by Langtangen), but the style is more accessible and concise, in keeping with the needs of engineering students. The book outlines the shortest possible path from no previous experience with programming to a set of skills that allows the students to write simple programs for solving common mathematical problems with numerical methods in engineering and science courses. The emphasis is on generic algorithms, clean design of programs, use of functions, and automatic tests for verification. |
The agri-food sector is subject to various sources of uncertainty and risk that can have a negative impact on its supply chain performance if not properly managed. In order to determine what actions the supply chain (SC) should take to protect itself against risks, it is necessary to analyze whether the supply chain is robust to them. This paper proposes a tool based on a system dynamics model to determine the robustness of an already designed five-stage fresh agri-food supply chain (AFSC) and its planting planning to disruptions in demand, supply, transport, and the operability of its nodes. |
This book aims to narrate fundamental concepts of structural design to architecture students such that they have minimum involvement with math problem-solving. Within this book, students learn about different types of loads, forces and vector addition, the concept of equilibrium, internal forces, geometrical and material properties of structural elements, and rules of thumb for estimating the proportion of some structural systems such as catenary cables and arches, trusses, and frame structures. |
We use the associated ground states and some sharp Gagliardo–Nirenberg inequalities. Moreover, we investigate the L2 concentration of the mass-critical blowing-up solutions. Finally, in the attractive regime, we prove the scattering of energy global solutions. Since there is a loss of regularity in Strichartz estimates for the fractional Schrödinger problem with nonradial data, in this work, we assume that u|t=0 is spherically symmetric. The blowup results use ideas of the pioneering work by Boulenger el al. (J. Funct. Anal. 271:2569–2603, 2016). |
In the design of digital logic circuits, QCA technology is an excellent alternative to CMOS technology. Its advantages over CMOS include low power consumption, fast circuit switching, and nanoscale design. Circuits that convert data between different formats are code converters. Code converters have an essential role in high-performance computing and signal processing. In this paper, first, we proposed a novel QCA structure for the quantum reversible Fredkin gate. Second, we proposed 4-bit and 8-bit QCA binary-to-gray converter and vice versa. For the second proposal, both reversible and irreversible structures are suggested. The proposed structures are scalable up to N bits. To change the conversion type from B2G to G2B, we use a 2:1 QCA multiplexer. The proposed QCA Fredkin is app... |
This open access book examines the interactions between India’s economic development, agricultural production, and nutrition through the lens of a “Food Systems Approach (FSA).” The Indian growth story is a paradoxical one. Despite economic progress over the past two decades, regional inequality, food insecurity and malnutrition problems persist. Simultaneously, recent trends in obesity along with micro-nutrient deficiency portend to a future public health crisis. This book explores various challenges and opportunities to achieve a nutrition-secure future through diversified production systems, improved health and hygiene environment and greater individual capability to access a balanced diet contributing to an increase in overall productivity. The authors bring together the latest ... |
This book is open access under a CC BY NC ND license. It addresses the most recent developments in cloud computing such as HPC in the Cloud, heterogeneous cloud, self-organising and self-management, and discusses the business implications of cloud computing adoption. Establishing the need for a new architecture for cloud computing, it discusses a novel cloud management and delivery architecture based on the principles of self-organisation and self-management. This focus shifts the deployment and optimisation effort from the consumer to the software stack running on the cloud infrastructure. It also outlines validation challenges and introduces a novel generalised extensible simulation framework to illustrate the effectiveness, performance and scalability of self-organising and self-... |
Since the appearance of the seminal paper of Frankel and Romer (Am Econ Rev 89(3): 379–399, 1999), ‘Does trade cause growth?’, the impact of aggregate trade openness on income has been controversial. This research shows that the type of product that is traded has first-order effects, while overall trade intensity has second-order effects on per capita income because of (i) the hierarchical structure of learning-by-doing in products with different levels of sophistication of the production processes; and (ii) the fertility and education effects of trade specialization following the quantity–quality tradeoff framework of Galor and Mountford (Am Econ Rev 96(2): 299–303, 2006). Using data on trade disaggregated by the level of technological sophistication of the production process for 2... |
