Acoustics of Small Rooms

Acoustics of Small Rooms

Much time is spent working out how to optimize the acoustics of large rooms such as auditoria but the acoustics of small rooms and environments can be just as vital. The expensive sound equipment of a recording studio or the stereo in a car or living room is likewise rendered useless if the acoustic environment is not right for them. Changes in wavelength to room size ratio and the time difference between the direct and reflected sound at the listening location mean that the acoustics of small spaces are quite different to those of large spaces. Tackling these specific aspects of physics sound perception and applications for small spaces Acoustics of Small Rooms brings together important facets of small room acoustics. Divided into clear sections it covers: Sound propagation—the effects of boundaries sound absorbers and time conditions Physiology and psychoacoustics Methods and techniques of room and sound field optimization Examples of how these principles apply in real situations Measurement and modeling techniques

Small Wars and Insurgencies in Theory and Practice 1500-1850

Small Wars and Insurgencies in Theory and Practice 1500-1850

In early modern times warfare in Europe took on many diverse and overlapping forms. Our modern notions of ‘regular’ and ‘irregular’ warfare of ‘major war’ and ‘small war’ have their roots in much greater diversity than such binary notions allow for. While insurgencies go back to time immemorial they have become conceptually fused with ‘small wars’. This is a term first used to denote special operations often carried out by military companies formed from special ethnic groups and then recruited into larger armies. In its Spanish form guerrilla the term ‘small war’ came to stand for an ideologically-motivated insurgency against the state authorities or occupying forces of another power. There is much overlap between the phenomena of irregular warfare in the sense of special operations alongside regular operations and irregular warfare of insurgents against the regular forces of a state. This book demonstrates how long the two phenomena were in flux and fed on each other from the raiding operations of the 16th century to the ‘small wars’ or special operations conducted by special units in the 19th century which existed alongside and could merge with a popular insurgency. This book is based on a special issue of the journal Small Wars & Insurgencies. | Small Wars and Insurgencies in Theory and Practice 1500-1850

Security-First Compliance for Small Businesses

Security-First Compliance for Small Businesses

Organizations of all sizes struggle to secure their data in a constantly evolving digital landscape. Expanding digital footprints and the rapid expansion of cloud strategies arising from the COVID-19 pandemic increase an organization’s attack surface. When combined with limited resources caused by the cybersecurity skills gap securing small and mid-sized business IT infrastructures becomes more complicated. With limited staffing and budgetary restrictions small businesses need to create cost-effective security-driven programs that protect data while also meeting increasingly stringent compliance requirements. This book bridges the gap between complex technical language and business objectives to create a security-first review of the security and compliance landscapes. Starting from the premise that “with security comes compliance ” this book starts by defining “security-first” and then walking readers through the process of creating a holistic security and compliance program. Looking at security and privacy through the lens of zero trust this overview of regulations and industry standards provides both background about and implications drawn from modern security practices. Rather than focusing solely on individual cybersecurity frameworks this book offers insights into best practices based on the commonalities between regulations and industry standards highlighting some of the primary differences to show the nuances. Woven throughout are practical examples of solutions that enable small and mid-sized businesses to create “cybersustainable” security-focused policies processes and controls that protect today’s future for tomorrow’s digital ecosystem. | Security-First Compliance for Small Businesses

Climate Change Impacts on the Stability of Small Tidal Inlets

Climate Change Impacts on the Stability of Small Tidal Inlets

This work explores coastal zones in the vicinity of tidal inlets which are commonly utilized for navigation sand mining waterfront developments and fishing and recreation are under particularly high population pressure and will only be exacerbated by foreshadowed climate change (CC). Although few recent studies have investigated CC impacts on very large tidal inlet systems the nature and magnitude of CC impacts on the more commonly found small tidal inlets (STIs) remains practically un-investigated to date. The combination of pre-dominant occurrence in developing countries socio-economic relevance and low community resilience general lack of data and high sensitivity to seasonal forcing makes STIs potentially very vulnerable to CC impacts. This study was undertaken to develop methods and tools that can provide insights on potential CC impacts on STIs and to demonstrate their application to assess these CC impacts. Two process based snap-shot modeling approaches for data poor and data rich environments are used to assess CC impacts and an innovative reduced complexity model is developed to obtain rapid predictions of CC impacts on the STI’s stability. Results show that STIs are unlikely to change their types but that their stability level is likely to change under CC impacts. The main driver for the change is the future variations in wave directions not SLR as is commonly thought. | Climate Change Impacts on the Stability of Small Tidal Inlets

Fish Swimming in Turbulent Waters Hydraulic Engineering Guidelines to assist Upstream Passage of Small-Bodied Fish Species in Standard Box

Fish Swimming in Turbulent Waters Hydraulic Engineering Guidelines to assist Upstream Passage of Small-Bodied Fish Species in Standard Box

Low-level river crossings including culverts are important for delivering a range of valuable socioeconomic services including transportation and hydrological control. These structures are also known to have negative impacts on freshwater river system morphology and ecology including the blockage of upstream fish passage particularly small-body-mass fish species. Given the enormous environmental problems created by road crossings new hydraulic engineering guidelines are proposed for fish-friendly multi-cell box culvert designs. The focus of these guidelines is on smooth box culverts without appurtenance with a novel approach based upon three basic concepts: (I) the culvert design is optimized for fish passage for small to medium water discharges and for flood capacity for larger discharges (II) low-velocity zones are provided along the wetted perimeter in the culvert barrel and quantified in terms of a fraction of the wetted flow area where the local longitudinal velocity is less than a characteristic fish speed linked to swimming performances of targeted fish species and (III) the culvert barrel is smooth without any other form of boundary treatment and appurtenance. The present monograph develops a number of practical considerations in particular relevant to box culvert operations for less-than-design discharges. It is argued that upstream fish passage capabilities would imply a revised approach to maintenance in part linked to the targeted fish species. This reference work is authored for civil and environmental engineers as well as biology and ecology scientists interested in culvert design. While the book is aimed to professionals the material is also lectured in postgraduate courses and in professional short courses. | Fish Swimming in Turbulent Waters Hydraulic Engineering Guidelines to assist Upstream Passage of Small-Bodied Fish Species in Standard Box

The Future of Entrepreneurship in Africa Cross-Sectoral Perspectives Post COVID-19

The Future of Entrepreneurship in Africa Cross-Sectoral Perspectives Post COVID-19

Thsi book focuses on entrepreneurial development and the development of small businesses in Africa. The central idea of this book is that entrepreneurial development and small business development are connected. Entrepreneurship is lauded as an engine of growth (economic development and job creation) with small businesses often contributing to new job creation. Also entrepreneurship and small business development are the heart of many countries’ economies. The decision to focus on entrepreneurial development and small business development is that first there is a consensus that most entrepreneurial activities are aimed at creating small new ventures. Second countries that give special attention to entrepreneurship stand a chance of industrialization. Third Africa has been reported as having a rich entrepreneurial landscape as the continent’s wealthiest individuals generated their wealth as trailblazing entrepreneurs. Fourth small-scale entrepreneurs and businesses form the backbone of economic activities across the continent. A motivation to focus on entrepreneurial and small business development is the generally accepted view that start-ups in Africa are growing calling for understanding into how to enhance productivity efficiencies and application of new technologies. The book aims to enhance the understanding of stakeholders (business owners governments practitioners) to overturn challenges such as inadequate start-up capital competition lack of employees with the right skills and low use of technology. The ability to develop entrepreneurship in Africa and the role of small-medium enterprises cannot be underestimated. The promotion of entrepreneurship in Africa is crucial as it creates jobs provides decent livelihoods and contributes to GDP. Most entrepreneurial initiatives in developing economies entail identifying opportunities and new venture creation. It is worth recognizing that most new ventures created take the form of small businesses and the entrepreneurial processes involve entrepreneurs’ knowledge and skills identifying opportunities involvement in setting up a business and managing the business. The various aspects of this book focus on many entrepreneurial activities that are undertaken on the African continent. This book is focused on African countries since there is a reason to be optimistic about the prospects for growth and entrepreneurship. To achieve entrepreneurial success in African countries the African Development Bank (2021) proposes that there must be a link between macro and firm-level characteristics that will serve as the mix of entrepreneurship in societies. This book therefore considers some macro-level factors such as education training and skills development technological developments government programs and entrepreneurial challenges and opportunities. At the firm-level this book focuses on entrepreneurial initiatives such as branding and marketing. | The Future of Entrepreneurship in Africa Cross-Sectoral Perspectives Post COVID-19

Low Head Hydropower for Local Energy Solutions

Low Head Hydropower for Local Energy Solutions

The role of small hydropower is becoming increasingly important on a global level. Increasing energy demand and environmental awareness has further triggered research and development into sustainable low-cost technologies. In developing countries particularly in rural areas the possibility of local power generation could considerably improve living conditions. With this in mind the development of a next generation low-head hydropower machines was subject of investigation in the EU-project HYLOW. Being part of the research lines of that project this thesis presents a numerical modelling approach to improve the design of machines like water wheels for increased hydraulic efficiency. Nowadays Computational Fluid Dynamics (CFD) enables numerical models to be quite accurate and incorporate physical complexities like free surfaces and rotating machines. The results of the CFD simulations carried out in this research show that a change in blade geometry can result in higher torque levels thereby increasing performance. Numerical simulations also enabled to determine the optimal wheel-width to channel-width ratio and further improve performance by modifying the channel bed conditions upstream and downstream of the water wheel. With a power rating in the low kilowatt range low-head hydropower machines like optimised water wheels seem to have a clear potential for small-scale energy generation thereby contributing to achieving the Sustainable Development Goals by providing local energy solutions. | Low Head Hydropower for Local Energy Solutions
