Sistem GPS Pada Quadcopter Sebagai Pendeteksi Posisi Korban Bencana Banjir
No full textDaerah di Indonesia sudah seringkali dilanda banjir, dan selalu menimbulkan permasalahan, seperti menyebabkan korban jiwa hingga menimbulkan kerugian ekonomi. Banjir yang meluap hingga di jalanan dapat menimbulkan lumpuhnya jalur transportasi, oleh karena itu pada pencarian korban banjir dibutuhkan alat bantu berupa quadcopter. Quadcopter bisa diterbangkan pada area yang sulit dijangkau untuk menemukan korban yang selamat.
Untuk mengetahui posisi dari korban banjir, quadcopter menggunakan kamera yang mampu membantu pencarian korban. Kamera yang digunakan adalah thermal camera FLiR Lepton 2 mampu mendeteksi korban pada malam hari dan mampu membedakan antara makhluk hidup dan benda mati. Quadcopter juga menggunakan sistem GPS yang menggunakan GPS U-Blox Neo 6M. Pada saat kamera mendeteksi korban maka GPS mengirimkan data berupa koordinat dari posisi korban bencana banjir, GPS juga berfungsi untuk melacak koordinat lokasi pada quadcopter. Untuk menampilkan koordinat pada quadcopter, digunakan GUI (Graphic User Interface) yang telah diprogram melalui python 2.7 dan Pyqt. Quadcopter dikomunikasikan dengan menggunakan Wireless yang dilengkapi dengan adapter TL-WN722N.
Hasil dari penelitian ini adalah koordinat quadcopter dapat ditampilkan secara real time pada GUI yang telah dibuat dengan tingkat keakurasian GPS 99%. Menjangkau tempat yang luas dengan menggunakan wireless yang bisa menjangkau tempat kurang lebih 200m.

The area in Indonesia is often hit by floods Indonesia already, and
always cause problems, such as causing casualties to cause economic
losses. Floods that overflowed to the streets can pose of the crippled
public transportation, therefore on the search flood victims required
tools be quadcopter. Quadcopter flyable on hard to reach areas to find
survivors.
To know the position of the flood victims, the drones use a camera
that is capable of helping search victims. The camera used is thermal
cameras FLiR Leptons 2 capable of detecting victims at night and be
able to distinguish between living beings and inanimate objects.
Quadcopter also use GPS systems that use GPS U-Blox Neo 6 m. At the
moment the camera detects the victim then send data in the form of GPS
coordinates of the position of the victims of the floods, also serve to
track the GPS coordinates of the location at quadcopter. To display
coordinates at quadcopter, use the GUI (Graphic User Interface) which
has been programmed via python 2.7 and Pyqt. Drones are
communicated using the Wireless equipped with adapters TL-WN722N.

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

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
Get PDFFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied

Intern experience at CH���M Hill, Inc.: an internship report
Get PDFIncludes author's vita"Submitted to the College of Engineering of Texas A&M University in partial
fulfillment of the requirement for the degree of Doctor of Engineering."Includes bibliographical referencesA review of the author's internship experience with CH���M HILL, Inc.
during the period September 1975 through May 1976 is presented. During this nine month
internship the author worked as an Engineer II in the Industrial Processes discipline of this
large consulting engineering firm... The author's prime responsibility was as one of three
lead design engineers on the design of a large wastewater treatment facility for a pulp mill
in Hoquiam, Washington owned by ITT Rayonier Inc. The work generally consisted of the design
of individual treatment units and associated piping and pumping. The purpose of the project
was to provide wastewater treatment capabilities that would satisfy the effluent limitations
(standards) imposed upon the mill by the State of Washington Department of Ecology and the
U.S. Environmental Protection Agency. The author's assignment also entailed necessary
interaction with the project manager and other CH���M HILL design engineers and support staff
members, the client's representatives, and representatives of two other consulting engineering
firms working on the project. Thus, the internship position at CH���M HILL provided considerable
experience coordinating the author's work with the work of other engineers, guiding the design
and administrative efforts of a support staff, and interacting regularly with the client and
other consulting firms. This broad exposure to a variety of engineering and organizational
problems provided a valuable educational experience
Transition to turbulence in a qblique shock-wave/boundary-layer interaction at M=15
No full textDirect numerical simulations are carried out for different forcing techniques to trigger transition during the interaction between an oblique shock-wave and a laminar boundary-layer at M = 1.5. Three forcing methods are used: a) forcing of oblique unstable modes, whose shape and behaviour are determined by the local linear stability theory, b) broadband free-stream acoustic disturbances, and c) a cold plasma flow control device. While the oblique-mode breakdown is dominant for low-amplitude forcing, long streaky structures drive the transition process in a high-amplitude disturbance environment. LES are also performed on the experimental setup by the Institute of Theoretical and Applied Mechanics (ITAM) from Novosibirsk State University with cold plasma actuation. As well as the disturbance type, the effect of Reynolds number and forcing amplitude will be investigated
