Design and efficiency

The study was conducted to determine the nitrogen use efficiency (NUE) and the ability to provide nitrogen from alluvial soil for growing pomelo (Citrus grandis L. Osbeck) in the Mekong Delta. The experiment was arranged in a randomized complete block design including two treatments (NPK treatment: 673 N - 385 P2O5 -192 K2O g/plant and PK treatment: 0 N - 385 P2O5 - 192 K2O g/plant) and three replicates (3 plants for each replicate).

The need for operating circuits at increasingly higher speeds has always challenged designers. From radar and television systems in the 1940s to gigahertz microprocessors today, the demand for pushing circuits to higher frequencies has required a solid understanding of their speed limitations. In this chapter, we study the effects that limit the speed of transistors and circuits, identifying topologies that better lend themselves to high-frequency operation.

This thesis examines how designs based on a conjunction between craft and digital techniques may offer new possibilities for an architect or designer in contemporary practice. How is it relevant that what initially appear to be two distinct approaches to designing and making can be introduced to each other and coalesce to form a constructive attitude of mutually borrowed logic? The thesis champions the crafting of innovative design and the incorporation of digitally derived procedures that allow for globally efficient dissemination and malleability.

The main objective of this research is to optimize the design of the Tunnel kiln for efficient fuel usage. To achieve that, the temperature distribution from the simulation needs be matched with the desired Tunnel kiln curve found in industry. This objective can be achieved by CFD simulation where temperature, velocity and emission distributions inside the Tunnel kiln can be obtained. Generated temperature distribution can be matched with the industrial curve and by interpreting the curve, efficient design can be suggested.

The design proposed in this thesis aims to reduce the distortion in Class-D Amplifier output at the cost of increased complexity in the implementation. The thesis is focussed on the DSP components of the unique design. State-ofthe-art FPGAs have been used as the implementation platform for these systems due to advantages such as abundant logic resources, ease of programming and re-configurability. The results demonstrate advantages of SWL processing systems in terms of efficient hardware utilization.

The aim of this thesis is investigate and design a small antenna which can be embedded onto a Polyethylene substrate (used for making roof tiles). The antenna can be used to harvest ambient energy by connecting it to a rectifier. Due to the dimensional constraints of a roof tile as well as the materials used, there are limitations imposed on the antenna size, and thus the radiation efficiency and bandwidth often become a limiting factor in the overall performance of the system.

Feedback is an integral part of our lives. Try touching your fingertips with your eyes closed; you may not succeed the first time because you have broken a feedback loop that ordinarily “regulates” your motions. The regulatory role of feedback manifests itself in biological, mechanical, and electronic systems, allowing precise realization of “functions.” For example, an amplifier targeting a precise gain of 2.00 is designed much more easily with feedback than without.
