    Mounds of the North: Discerning the nature of Earth Mounds in North Australia

    This thesis is dedicated to the study of late Holocene Earth Mound sites in two separate regions in northern Australia: Weipa, Cape York Peninsula; and the South Alligator River floodplains, Kakadu National Park, Northern Territory. Broadly speaking, Earth Mounds are shallow mounds of earth that have been left in the landscape by the people of the past. These sites typically present little, if any visually discernible stratigraphy and yield few, if any cultural remains. Some sites can be difficult to differentiate from other archaeological site types (e.g. shell matrix sites), others can be difficult to differentiate from natural features (e.g. megapode mounds) and others still can be difficult to even identify in the landscape at all. Even in instances where Earth Mounds can be positively identified, it can often be difficult to progress past this fundamental point. Earth Mounds are at their heart, enigmatic archaeological sites and yet their careful study can prove to be fruitful. This thesis chronicles the last half a century of study of Earth Mounds in Australia and presents new archaeological fieldwork undertaken in two separate regions in northern Australia. This thesis compares archaeological Earth Mounds with natural features in the landscape and demonstrates how and why they are different on both micro and macroscopic levels through the use of revealing, soil-based post-excavation analyses. These analyses reveal some of the mechanisms behind anthropogenically modified Earth Mound soils and human-engineered firing, and how these compare to natural soils and the by-products of natural processes. In addition to investigating faunal and modified stone assemblages, this thesis also analyses termite mound heat retainers on a crystalline level in order to compare these artefacts with naturally baked termite clay. This thesis compares information from a range of Earth Mounds within the same study areas across different microenvironments, and from sites and environments across these two separate regions of northern Australia. This thesis demonstrates that these sites exhibit nuanced and regionally specific variations that require equally nuanced and individually tailored methodologies to investigate and interpret. Importantly, this thesis demonstrates how and why listening to local Traditional Owners was crucial throughout every stage of this project. Listening to experts today does not provide a blueprint of the past, but it can highlight some of the questions that need to be asked about the past. This thesis will also compare its archaeological findings with the results of an extensive survey of both regions' ethnographic corpora. This work will demonstrate why Earth Mounds are important archaeological sites in their own right, and how their study can contribute to larger archaeological discourses. The study of Earth Mounds contributes to palaeoenvironmental research and furthers the understanding of past relationships between people and their environments, including cultural responses to environmental change in the late Holocene. This thesis will demonstrate the complexity and importance of Earth Mounds in northern Australia, both in the archaeological record, and in living, breathing cultural landscapes today

    How does coding change the way we think about architecture? Miro Roman and his AI Alice_ch3n81 develop a playful scenario in which they propose coding as the new literacy of information. They convey knowledge in the form of a project model that links the fields of architecture and information through two interwoven narrative strands in an “infinite flow” of real books

    The Art of Insight in Science and Engineering

    Tools to make hard problems easier to solve.In this book, Sanjoy Mahajan shows us that the way to master complexity is through insight rather than precision. Precision can overwhelm us with information, whereas insight connects seemingly disparate pieces of information into a simple picture. Unlike computers, humans depend on insight. Based on the author's fifteen years of teaching at MIT, Cambridge University, and Olin College, The Art of Insight in Science and Engineering shows us how to build insight and find understanding, giving readers tools to help them solve any problem in science and engineering.To master complexity, we can organize it or discard it. The Art of Insight in Science and Engineering first teaches the tools for organizing complexity, then distinguishes the two paths for discarding complexity: with and without loss of information. Questions and problems throughout the text help readers master and apply these groups of tools. Armed with this three-part toolchest, and without complicated mathematics, readers can estimate the flight range of birds and planes and the strength of chemical bonds, understand the physics of pianos and xylophones, and explain why skies are blue and sunsets are red.The Art of Insight in Science and Engineering will appear in print and online under a Creative Commons Noncommercial Share Alike license

    ENERGY CONSUMPTION OF MOBILE PHONES

    Battery consumption in mobile applications development is a very important aspect and has to be considered by all the developers in their applications. This study will present an analysis of different relevant concepts and parameters that may have an impact on energy consumption of Windows Phone applications. This operating system was chosen because limited research related thereto has been conducted, even though there are related studies for Android and iOS operating systems. Furthermore, another reason is the increasing number of Windows Phone users. The objective of this research is to categorise the energy consumption parameters (e.g. use of one thread or several threads for the same output). The result for each group of experiments will be analysed and a rule will be derived. The set of derived rules will serve as a guide for developers who intend to develop energy efficient Windows Phone applications. For each experiment, one application is created for each concept and the results are presented in two ways; a table and a chart. The table presents the duration of the experiment, the battery consumed in the experiment, the expected battery lifetime, and the energy consumption, while the charts display the energy distribution based on the main threads: UI thread, application thread, and network thread

    A WEB-BASED ENVIRONMENTAL TOOLKIT TO SUPPORT SMES IN THE IMPLEMENTATION OF AN ENVIRONMENTAL MANAGEMENT SYSTEM

    With small and medium sized-enterprises (SMEs) taking up the majority of the global businesses, it is important they act in an environmentally responsible manner. Environmental management systems (EMS) help companies evaluate and improve their environmental impact but they often require human, financial, and temporary resources that not all SMEs can afford. This research encompasses interviews with representatives of two small enterprises in Germany to provide insights into their understanding, and knowledge of an EMS and how they perceive their responsibility towards the environment. Furthermore, it presents a toolkit created especially for small and medium-sized enterprises. It serves as a simplified version of an EMS based on the ISO 14001 standard and is evaluated by target users and appropriate representatives. Some of the findings are: while open to the idea of improving their environmental impact, SMEs do not always feel it is their responsibility to do so; they seem to lack the means to fully implement an EMS. The developed toolkit is considered useful and usable and recommendations are drawn for its future enhancement

    We are pleased to present you this Book of Abstracts, which contains the submitted contributions to the "Energy, Science and Technology Conference & Exhibition EST 2015". The EST 2015 took place from May, 20th until May, 22nd 2015 in Karlsruhe, Germany, and brought together many different stakeholders, who do research or work in the broad field of "Energy". Renewable energies have to present a relevant share in a sustainable energy system and energy efficiency has to guarantee that conventional as well as renewable energy sources are transformed and used in a reasonable way. The adaption of existing infrastructure and the establishment of new systems, storages and grids are necessary to face the challenges of a changing energy sector. Those three main topics have been the fundament of the EST 2015, which served as a platform for national and international attendees to discuss and interconnect the various disciplines within energy research and energy business. We thank the authors, who summarised their high-quality and important results and experiences within one-paged abstracts and made the conference and this book possible. The abstracts of this book have been peer-reviewed by an international Scientific Programme Committee and are ordered by type of presentation (oral or poster) and topics. You can navigate by using either the table of contents (page 3) or the conference programme (starting page 4 for oral presentations and page 21 for posters respectively)
