Abstract:

Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, February 2008.<br>Includes bibliographical references (p. 49-50).<br>Current techniques for characterizing the power consumption of adders rely on assuming that the inputs are completely random. However, the inputs generated by realistic applications are not random, and in fact include a great deal of structure. Input bits are more likely to remain in the same logical states from addition to addition than would be expected by chance and bits, especially the most significant bits, are

Abstract:

Master of Science<br>Agricultural Economics<br>Jason S. Bergtold<br>The use of elasticities of substitution between inputs has become the standard method for addressing the effect of a change in the mix of input used for production from a technological or cost standpoint. (Chambers 1988) A researcher that wants to estimate this elasticity, or some other comparative static, typically would do so using parametric production or cost function (e.g. translog or normalized quadratic) with panel data. For a study with only cross-sectional data, the construction of such a function may be problematic.

This paper presents the development and study of multiple-input single-output converter (MISO) for the DC House project that utilizes a controller to maximize the overall converter’s efficiency. The premise of this thesis is to create uneven load current sharing between the converters at different loading conditions in order to maximize the efficiency of the overall MISO converter. The goal is to find a proper ratio of current from each converter to the total load current of the MISO system to achieve the greatest efficiency.

Abstract:

Spatial Modulation (SM) is a Multiple-Input Multiple-Output (MIMO) transmission technique which realizes low complexity implementations in wireless communication systems. Due the transmission principle of SM, only one Radio Frequency (RF) chain is required in the transmitter. Therefore, the complexity of the transmitter is lower compared to the complexity of traditional MIMO schemes, such as Spatial MultipleXing (SMX). In addition, because of the single RF chain configuration of SM, only one Power Amplifier (PA) is required in the transmitter. Hence, SM has the potential to exhibit significant

Abstract:

Most countries show a relative decoupling of economic growth from domestic resource use, implying increased resource efficiency. However, international trade facilitates the exchange of products between regions with disparate resource productivity. Hence, for an understanding of resource efficiency from a consumption perspective that takes into account the impacts in the upstream supply chains, there is a need to assess the environmental pressures embodied in trade. We use EXIOBASE3, a new multiregional input-output database, to examine the rate of increase in resource efficiency, and in

This dissertation studies agricultural input intensification, defined as the increased use of modern inputs such as hybrid seeds, mineral fertilizer, herbicide, and pesticide in African agriculture. It also analyses the potential of this intensification to accelerate productivity growth and tests the effectiveness of two policies, input subsidies and land reforms, in promoting it and consequently in increasing crop yield. In the first essay, we argue that to create the conditions for the emergence of a green revolution in Africa, modern agricultural technologies have to be adopted as a package

Abstract:

The UK has committed to deep, long-term reductions in national greenhouse gas emissions as part of a global effort to address climate change. Material efficiency, reducing the material inputs per service output, has long been identified as a globally underexplored mitigation strategy. Previous studies show unrealised technical potential to improve the efficiency of steel use, a large contributor of industry emissions, in the UK. This thesis explores why these opportunities may be unrealised along the steel supply chain.

Non-orthogonal multiple access (NOMA) has attracted a great attention recently due to its superior spectral efficiency (SE) over orthogonal multiple access and could play a vital role in improving the capacity of future networks.

High efficiency of power converters placed between renewable energy sources and the utility grid is required to maximize the utilization of these sources.

This paper serves as an introduction to this special issue on the use of multiregional input- output modeling in assessments of natural resource use and resource use efficiency.

Various methods have been developed to perform so-called footprint analyses.

Abstract:

Understanding the environmental implications of consumption and production depends on appropriate monitoring tools. Material flow accounting (MFA) is a method to monitor natural resource use by countries and has been widely used in research and policy. However, the increasing globalization requires the consideration of "embodied" material use of traded products. The indicator raw material consumption (RMC) represents the material use - no matter where in the world it occurs - associated with domestic final demand. It provides a consumption-based perspective complementary to the MFA indicators

碩士<br>淡江大學<br>經濟學系應用經濟學碩士班<br>91<br>Since Sandmo (1971) has proposed a framework of the maximizationof the expected utility function of profits to analyze how price uncertainty influences firms’ output decisions, most studies in the same area follow the silmilar way. Different from those, this paper starts with cost minimization. The main objective is to find how firms adjust their input demand under production risk and financial pressure, and to measure efficiency and total factor productivity using listed companies of Taiwan’s manufacturing in the period 1986-2001. 　　The article i

碩士<br>東吳大學<br>企業管理學系<br>102<br>As popularity of mobile internet and smartphones, people can be connected with others through a variety of input methods on instant message by smartphones. There were some related studies of input interface in the past. However, as technology improves every day, the technology of input method has been well developed and the correction rate of recognition also improved dramatically. Therefore, this study re-explored the usability of input interface. An experiment was constructed to study the input performances among different input methods, and using questionary t

博士<br>國立交通大學<br>經營管理研究所<br>99<br>Traditional productivity measures neglect the substitution or complement effects among all factors and do not distinguish between the contribution due to technical change and changes in efficiency. The total-factor productivity index, such as Malmquist and Luenberger productivity indices, may not evaluate single factor productivity change under a total-factor framework. Therefore, this dissertation introduces a total-factor input productivity index (TIPI), based on the Luenberger productivity index, to calculate one particular input productivity change with a

This research intended to explore usability and efficiency of computer input devices among older people by the thought of Universal Design. This research was carried out by means of interview and experiment. 72 older people were selected from classes in Taipei Community University and Institute of Elders in Taipei County

The results show the 76 ITHs having an average of 93.3%, the number of guest rooms and total floor spaces of catering divisions are the main factors cause congestion by comparing each input congestion efficiency. We then use a Tobit regression to estimate the effects of tourist nationalities (local, overseas Chinese, Asian, Japan

Energy is an important input factor for enhancing both economy development and living standard in a country. After the second energy crisis, the world faced a certain period of low oil price. At the same time, the government put great afforts to improve the economy growth in Taiwan . It also stimulated the demand to energy in Taiwan. According to the empirical result, we observe the energy efficiency indicator to understand the relationship between energy input and the output in industries. The

碩士<br>國立中山大學<br>海洋地質及化學研究所<br>97<br>The purposes of this study are to investigate the sources, distributions, fluxes and phosphorus burial efficiency (PBE) of particulate phosphorus in the Gaoping (GP) coastal sea. The GP River carried about 3.14 × 104 ton yr-1 (1.03 × 109 mol yr-1) particulate P into the GP coastal sea. The total P flux was primarily determined by the river runoff during the May-yu (monsoon) and typhoon seasons. The river P was approximately consisted of 90.8% particulate inorganic-P (PIP), 7.4% particulate organic-P (POP), 1.5% dissolved inorganic-P (DIP) and 0.3% dissolv
