A novel implementation is proposed to relax the specifications of the internal feedback path for a continuous-time delta-sigma modulator. A truncator is embedded into the digital excess loop delay (ELD) compensation path. Thermometer-coded truncation is achieved by re-ordering the reference voltages of the internal quantiser. This requires only a small...
Contrasting the productive ground gained in ecological rhetorical theory through embedded fieldwork, composition as a discipline has yet to enact such transformative engagements with ecology. In this thesis, I put forward a praxis for ecological rhetoric and composition through permaculture design, utilizing the design framework’s system of ethics and principles...
The Component Object Model (COM) defines a completely standardized mechanism for creating objects and for clients and objects to communicate. Unlike traditional object-oriented programming environments, these mechanisms are independent of the applications that use object services and of programming languages used to create the objects. In the present work, a...
CREEDA (Crop Rotation Economic and Environmental Impact Decision Aid) is a Windows application for assessing economic and environmental impacts of agricultural activities. In implementing it, we extended the ProCosts database and incorporated the RUSLE (Revised Universal Soil-Loss Equation) application and the SCI (Soil Conditioning Index) application as COM components. ProCosts,...
Els grups d’investigació d’arreu del món són cada cop més interdisciplinaris i heterogenis, i generen cada cop més dades. Gestionar amb cura aquestes dades de recerca és complicat, especialment perquè els canvis tecnològics que acompanyen aquestes dades són molt ràpids. La quantitat de dades, els formats en què s’emmagatzemen, els...
Growing trees as a green manure crop together with an annual food crop is a new technology for farmers in Oregon. To promote farmer participation and to acquire a broad knowledge of the processes involved in species interactions, three feasible alley cropping and two sweet corn monocrop planting patterns were...
A highly-digital technique is proposed for excess loop delay (ELD)
compensation in multi-bit continuous-time ΔΣ modulators. A digitally
controlled reference switching matrix is used to replace the power-hungry
signal adder and extra DAC driving the quantizer, which are
commonly used in ELD compensation. With the proposed technique,
the feedback DAC...
It has been previously suggested that the walking pattern of individuals with Down syndrome is inefficient. This is thought to result from increased instability, particularly in the medio-lateral direction, due to the characteristic joint laxity and muscle hypotonia of individuals with DS. Therefore, this work was an attempt to gain...
