Industrial automation in laser manufacturing
No full textWith the rapid development and proliferation of PLCs and other software technologies, manufacturing in industries has changed drastically from manual to automation.The following report shows one such e ort of fully automating a laser-manufacturing machine that assembles and tests the laser diodes at lower costs. This includes development of hardware and software for a laser testing equipment, which completely eliminates the human error and increases the product manufacturing efficiency. In developing such fully automated system a 3-axis Cartesian Robot is used with the help of LabVIEW and some other sensors& actuators. The code written in LabVIEW to control Robot provides solutions to use LabVIEW as main interface for any automation project. The developed algorithms for testing and pick & place provides the project with the needed time and cost effectiveness.M.S.Includes bibliographical referencesby Bharath Kumar Molakala Jayarama Naid
A multiscale approximation algorithm for the cardinality constrained knapsack problem
Get PDFThesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2006.Includes bibliographical references (leaves 83-86).I develop a multiscale approximation algorithm for the cardinality constrained knapsack problem. The algorithm consists of three steps: a rounding and reduction step where a hierarchical representation of the problem data ranging from coarse to fine is generated, a solution step where a coarse solution is computed, and a refinement step where the accuracy of the solution is improved by refining the problem representation. I demonstrate that the algorithm is fully polynomial with a runtime complexity that improves upon the previous best known fully polynomial approximation scheme. Through an extensive computational study, I show that the running times of the algorithm is less than or equal to that of a commercial integer programming package with little loss in solution accuracy.by Bharath Kumar Krishnan.Ph.D

Towards Reliable User Collaboration over Cloud-based File Synchronization System:Dropbox as a Case Study
No full textUniversity of Minnesota M.S. thesis.July 2016. Major: Computer Science. Advisor: Haiyang Wang. 1 computer file (PDF); viii, 63 pages.Recent advances in cloud technology have turned the idea of Cloud Storage into a reality. Over the past few years, cloud-based file storage/synchronization systems such as Dropbox, Google Drive and One Drive, have gained tremendous success among Internet users. The cloud storage systems, most notably Dropbox, not only provide reliable file storage but also enable effective file synchronization with diverse user collaborations. It is thus interesting to explore if this cloud-based file storage system can provide reliable collaboration service for the users. In this thesis, we, for the first time, collect samples of content shared on Dropbox and analyze it. We then take our first step to understand the reliable user collaboration over cloud-based file storage systems using the popular Dropbox as a case study. Our observations indicate that users' updates would be discarded without any warning in a classic collaborative file editing session on Dropbox like file storage systems. In particular, to ensure a reliable service, the users need to wait for over 40 seconds between two updates when their uploading capacity is lower than 100 KBytes/sec. This already exceeds the auto-saving interval of many real world applications and severely hinders the system applicability. We further investigate the root causes of this phenomenon and find that such a problem is due to the three-layer design(i.e. user client, cloud virtual machines and cloud storage) of cloud storage systems. To address this problem of losing updates in multi-user collaborative file editing session, we propose an enhancement to the system that keeps track of and saves all the user updates locally and provides the opportunity for the recovery of any historical updates. Our proposed enhancement ensures that none of the user updates will be lost during a file editing session irrespective of the time interval between the updates and thereby making Dropbox user collaboration more resilient and less prone to potential data loss.Bommana, Bharath Kumar.

STRATEGIC ENGINEERING APPLIED TO COMPLEX SYSTEMS WITHIN MARINE ENVIRONMENT
No full textThe paper proposes an example of Strategic Engineering approach applied to a complex system related to Marine Environment with special attention to traffic control. This case represents an application of innovative discipline in terms of Strategic Management based on Artificial Intelligence, Modeling and Simulation to support decision makers while operating into a dynamic environment. The authors propose this methodological approach using data and extra information based on the strong combination of Simulation with other techniques. In facts the adoption of Strategic Engineering improves Strategic Management capabilities within Organizations or Institutions and the proposed case study is based on a realistic scenario and developed through different elements, models and simulators
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
