Field-effect Self-mixing Terahertz Detectors
by Jiandong SunA comprehensive device model considering both spatialdistributions of the terahertz field and the field-effect self-mixing factorhas been constructed for the first time in the thesis. The author has foundthat it is the strongly localized terahertz field induced in a small fractionof the gated electron channel that plays an important role in the highresponsivity. An AlGaN/GaN-based high-electron-mobility transistor with a2-micron-sized gate and integrated dipole antennas has been developed and canoffer a noise-equivalent power as low as 40 pW/Hz1/2 at 900 GHz. By furtherreducing the gate length down to 0. 2 micron, a noise-equivalent power of 6pW/Hz1/2 has been achieved. This thesis provides detailed experimentaltechniques and device simulation for revealing the self-mixing mechanismincluding a scanning probe technique for evaluating the effectiveness ofterahertz antennas. As such, the thesis could be served as a valuableintroduction towards further development of high-sensitivity field-effect terahertzdetectors for practical applications.

Field Guide to Compelling Analytics (Chapman and Hall/CRC Focus Case Studies in Analytics and OR)
by Walter DeGrange Lucia DarrowField Guide to Compelling Analytics is written for Analytics Professionals (APs) who want to increase their probability of success in implementing analytical solutions. In the past, soft skills such as presentation and persuasive writing techniques have been the extent of teaching junior APs how to effectively communicate the value of analytical products. However, there are other aspects to success such as trust and experience that may play a more important role in convincing fellow APs, clients, advisors, and leadership groups that their analytic solutions will work. This book introduces the formula ‘Analytics + Trust + Communication + Experience > Convince Them’ to illustrate an AP’s ability to convince a stakeholder. The ‘Convince Me’ stakeholders might be an analytics team member, team lead, decision-maker, or senior leader that are either internal or external to the AP’s organization. Whoever they are, this formula represents a concise, digestible, and above all practical means to increase the likelihood that you will be able to persuade them of the value of your analytical product. Features Includes insight questions to support class discussion. Written in broadly non-mathematical terms, designed to be accessible to any level of student or practicing AP to read, understand, and implement the concepts. Each section introduces the ideas through real-life case studies.

Field Guide to the Forest Trees of Uganda: For Identification and Conservation
by James Kalema Alan HamiltonThis book is a guide for the identification of the indigenous forest trees of Uganda. It will be useful for those who wish to contribute towards the conservation of the forests or to plant indigenous trees. Information is provided on how to propagate and cultivate about 80 of the most valuable species. Indigenous trees provide numerous resources useful for welfare and development. They include many types of timber and non-timber forest products, such as craft materials, foods and medicines. The proximity of indigenous forest helps to moderate the local climate, making it more suitable for agriculture. Indigenous forests protect springs, therefore safeguarding water supplies more effectively than exotic trees such as pines and eucalyptus. All 450 known indigenous tree species from the forests are included. Both scientific and local names are provided, the latter in 21 languages. Local names facilitate access to knowledge and values traditionally attached to the species, useful when planning pathways of development firmly rooted in local culture. The book will be invaluable for botanists, foresters, rural development workers and members of the general public concerned about contributing to conservation and sustainable development in Uganda. Many of the species grow in neighbouring countries, so the book has relevance there too.
The Field Guide to Understanding 'Human Error': Second Edtion
by Sidney DekkerWhen faced with a ’human error’ problem, you may be tempted to ask 'Why didn’t these people watch out better?' Or, 'How can I get my people more engaged in safety?' You might think you can solve your safety problems by telling your people to be more careful, by reprimanding the miscreants, by issuing a new rule or procedure and demanding compliance. These are all expressions of 'The Bad Apple Theory' where you believe your system is basically safe if it were not for those few unreliable people in it. Building on its successful predecessors, the third edition of The Field Guide to Understanding ’Human Error’ will help you understand a new way of dealing with a perceived 'human error' problem in your organization. It will help you trace how your organization juggles inherent trade-offs between safety and other pressures and expectations, suggesting that you are not the custodian of an already safe system. It will encourage you to start looking more closely at the performance that others may still call 'human error', allowing you to discover how your people create safety through practice, at all levels of your organization, mostly successfully, under the pressure of resource constraints and multiple conflicting goals. The Field Guide to Understanding 'Human Error' will help you understand how to move beyond 'human error'; how to understand accidents; how to do better investigations; how to understand and improve your safety work. You will be invited to think creatively and differently about the safety issues you and your organization face. In each, you will find possibilities for a new language, for different concepts, and for new leverage points to influence your own thinking and practice, as well as that of your colleagues and organization. If you are faced with a ’human error’ problem, abandon the fallacy of a quick fix. Read this book.

Field Informatics
by Toru IshidaHere we use the term "field" to refer to a sphere of practical operation, and correspondingly the term "field informatics" describes informatics tools and methodologies that arise in the field. The components of field informatics are description, prediction, design and transfer, and the methods for those components vary widely. For example, we consider the social goal of revitalizing a mountainous area experiencing depopulation and we show how the tools and methodologies of field informatics may be used to describe such situations using remote sensing, biologging, human sensing and ethnography; the effects of various solutions can be predicted using system dynamics and multiagent simulations; the solutions can be designed using inclusive design or participatory design methods; and finally the experience gained can be transferred using case writing and outreach communication. The authors are specialists in diverse areas such as informatics, engineering, agriculture, sociology and pedagogy, and their areas of interest range from environment conservation to social education for international cooperation. They have a particular focus on the environment in southeast Asia and related topics such as large-scale traffic simulations, participatory workshops, inclusive design workshops, distance learning, and intercultural collaboration. This book targets graduate students seeking tools and methodologies for natural observation, field workers engaged in social participation, and researchers and engineers pursuing innovation. The techniques described in the book could also be exploited by government officials to form consensus and develop activities or by non-profit organizations to undertake more effective social programs.
