Demonstration system for a low-power seismic detector and classifier
No full textThesis (S.M.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2003.Includes bibliographical references (p. 229-230).This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.A low-power seismic detector and classifier was designed and implemented which was able to detect the footsteps of a person from as far as 35 meters away. Throughout the design an emphasis was placed on using low power circuitry and efficient algorithms. The test platform to demonstrate the concepts of the design utilizes a revolutionary low-power microcontroller and Digital Signal Processor (DSP) from Texas Instruments, Inc. The DSP is a fixed-point processor that is underclocked to minimize power consumption and the microcontroller has idle modes which consume microamps of power. The system is designed to run on battery power, and uses solar power to continually charge the batteries during the day. Lastly, a "Commercial Off the Shelf" RF module allows multiple sensors to communicate with themselves to triangulate position, or to relay detections and commands to and from a base station.by Elliot Richard Ranger.S.M
A Review of the Efficient Markets Hypothesis & The Elliot Wave Analysis: An empirical Investigation
No full textSUMMARY
In his presentation of the Efficient Market Eugene F. Fama wished to create a coherent picture of the main lines of the work on efficient markets, along with an accurate picture of the current state of the arts. The objective of this dissertation is to present a 360 degree perspective of Efficient Markets, whilst using Fama's original work as a skeletal frame.
This dissertation has been divided into two parts. Part I is reserved for an in-depth qualitative discussion of Efficient Markets. The Efficiency of Markets is assumed throughout the discussion, and though any attack on this established fact would be futile, an attempt has been made to highlight and discuss the most notable cases of Inefficiency. Based on the arguments against efficiency, we also look at further implications of Efficient Markets on Investment Professionals, the impact Market Efficiency had on them and how they use it in today's world for their own benefit.
Based on the fact that Markets are Efficient, we move onto Part II. Here a new concept is introduced which may seem either brilliant or ludicrous. The Elliot Wave Analysis is a technical trend following tool that has been termed as one of the few challenges to Market Efficiency, along with the Dow Theory. This obscure and long forgotten theory is based on human psychology and (to some extent) the chaos theory, which states that there is a pattern within randomness.
Part II features an exhaustive review of this concept along with the main characteristics underlying this theory. After an introduction to the basic tenants of this theory, the author tries to create a model based on the Elliot Wave. Once a Model has been constructed, first a naive test is carried out employing the use of Microsoft Excel, and then a more formal approach is implemented using the statistical prowess of SPSS

Discrete multiple-valued dynamical systems
No full textIn this paper we introduce the idea of multiple valued iteration theory. For a set X and family of functions {\cal F} = \{ f\sb{i}\} \sb{i\in I} indexed by a countable set I, each f\sb{i} : X \to X, we consider all possible ways of forming the n\sp{th} iterate, for We study the dynamics of multiple valued maps which arise from functions of the form B\sb{r}(x) = rx (mod 1) as maps of the interval. For these systems, we determine the structure of orbits and study their discrete time averages.Made available in DSpace on 2011-05-07T12:40:25Z (GMT). No. of bitstreams: 2

Exploiting tacit knowledge through knowledge management technologies
No full textThe purpose of this paper is to examine the contributions and suitability of the available knowledge management (KM) technologies, including the Web 2.0 for exploiting tacit knowledge. It proposes an integrated framework for extracting tacit knowledge in organisations, which includes Web 2.0 technologies, KM tools, organisational learning (OL) and Community of Practice (CoP). It reviews a comprehensive literature covering overview of KM theories, KM technologies and OL and identifies the current state of knowledge relating to tacit knowledge exploitation. The outcomes of the paper indicate that Internet and Web 2.0 technologies have stunning prospects for creating learning communities where tacit knowledge can be extracted from people. The author recommends that organisations should design procedures and embed them in their Web 2.0 collaborative platforms persuading employees to record their ideas and share them with other members. It is also recommended that no idea should be taken for granted in a learning community where tacit knowledge exploitation is pursued. It is envisaged that future research should adopt empirical approach involving Complex Adaptive Model for Tacit Knowledge Exploitation (CAMTaKE) and the Theory of Deferred Action in examining the effectiveness of KM technologies including Web 2.0 tools for tacit knowledge exploitation

No full textCurrent concepts on oxidative/carbonyl stress, inflammation and epigenetics in pathogenesis of chronic obstructive pulmonary disease
No full textChronic obstructive pulmonary disease (COPD) is a global health problem. The current therapies for COPD are poorly effective and the mainstays of pharmacotherapy are bronchodilators. A better understanding of the pathobiology of COPD is critical for the development of novel therapies. In the present review, we have discussed the roles of oxidative/aldehyde stress, inflammation/immunity, and chromatin remodeling in the pathogenesis of COPD. An imbalance of oxidants/antioxidants caused by cigarette smoke and other pollutants/biomass fuels plays an important role in the pathogenesis of COPD by regulating redox-sensitive transcription factors (e.g., NF-κB), autophagy and unfolded protein response leading to chronic lung inflammatory response. Cigarette smoke also activates canonical/alternative NF-κB pathways and their upstream kinases leading to sustained inflammatory response in lungs. Recently, epigenetic regulation has been shown to be critical for the development of COPD because the expression/activity of enzymes that regulate these epigenetic modifications have been reported to be abnormal in airways of COPD patients. Hence, the significant advances made in understanding the pathophysiology of COPD as described herein will identify novel therapeutic targets for intervention in COPD
An Investigation of Engineering Decision-making in a California Clean Water Grant Project
No full textThe planning and design of an engineering project can be viewed as a series of decisions. It follows , therefore , that a project is well engineered when good decisions are made in an efficient manner. This investigation seeks to examine engineering decision making for the general purpose of providing insights which may improve the engineering decision-making process. The study centers around a project constructed under the Clean Water Grant Program in California. There are two reasons for this 1) the Clean Water Grant Program is presently (1979) the largest public works program in the United States and is therefore, significant to the field o f civil engineering in general, and 2) the author has worked in the program for several years. Despite the choice of a Clean Water Grant project, the investigation is, in most respects, illustrative of engineering decision -making in general and applicable to other types of projects. The first part of the investigation is an overview of engineering decision-making . Utilizing the literature, as well as examples from other Clean Water Grant projects, various bases on which decisions are made are explored considering also, some psycho logical aspects and philosophical implications of engineering decision-making. Also, some special too ls and approaches current in the engineering field are discussed. The second part investigates, in detail, the planning and design of wastewater facilities for the City of Taft, California. Its purposes area 1) to survey all decisions made in ·the planning and design of the project; and 2) to identify and discuss the basis of the decisions. The Taft project was selected for study for several reasons: 1) the limited scope of its design allowed the design decisions to be identified without becoming unwieldy; 2) it is typical of Clean Water Grant projects in many respects; 3) the planning and design were exceptionally well done; and 4) there were interesting and uncommon features to the project, especially in the planning phase. In addition, the project engineer was willing to discuss candidly the basis of the decisions in this project. This is in contrast with engineers on other projects, who, when approached by the author, were very reticent to discuss the true basis of their decisions. Finally, the author\u27s direct involvement in the project, by way of his duties working for the State Water Resources Control Board, greatly facilitated the investigation
