The Dialogue Of Type And Model In ArchitectureTuncbas, Adil 01 December 2006 (has links) (PDF)
The idea of type has always been a crucial factor in the field of architecture. Not only it works as a dominator in the design process of architecture but also it supplies the certain ways through which architecture communicates with the observer. In order to understand the interaction between architecture and the observer the idea of type appears as a critical point.
This study will be an attempt to understand the dialogue of type and model in architecture. Throughout the research Anthony Vidler&rsquo / s article &ldquo / Third Typology&rdquo / will be used as the main outline to see the development of type within the theory of architecture and various typologies. The interaction between type and model will be dealed as a field of communication where meaning in architecture is situated. In this attempt the theory of language will be the main reference to understand the relation between type and model.

Traffic Sign RecognitionAydin, Ufuk Suat 01 May 2009 (has links) (PDF)
Designing smarter vehicles, aiming to minimize the number of driverbased wrong decisions or accidents, which can be faced with during the drive, is one of hot topics of today&rsquo / s automotive technology. In the design of smarter vehicles, several research issues can be addressed / one of which is Traffic Sign Recognition (TSR). In TSR systems, the aim is to remind or warn drivers about the restrictions, dangers or other information imparted by traffic signs, beforehand. Since the existing signs are designed to draw drivers&rsquo / attention by their colors and shapes, processing of these features is one of the crucial parts in these systems. In this thesis, a Traffic Sign Recognition System, having ability of detection and identification of traffic signs even with bad visual artifacts those originate from some weather conditions or other
circumstances, is developed.
The developed algorithm in this thesis, segments the required color influenced by the illumination of the environment, then reconstructs the shape of partially occluded traffic sign by its remaining segments and finally, identifies it. These three stages are called as &ldquo / Segmentation&rdquo / , &ldquo / Reconstruction&rdquo / and &ldquo / Identification&rdquo / respectively, within this thesis. Due to the difficulty of analyzing partial segments to construct the main frame (a whole sign), the main complexity of the algorithm takes place in the &ldquo / Reconstruction&rdquo / stage.

Traffic Sign Detection Using FpgaOzkan, Ibrahim 01 May 2010 (has links) (PDF)
In this thesis, real time detection of traffic signs using FPGA hardware is presented. Traffic signs have distinctive color and shape properties. Therefore, color and shape
based algorithms are chosen to implemented on FPGA. FPGA supports sufficient logic to implement complete systems and sub-systems.
Color information of images/frames is used to minimize the search domain of detection process. Using FPGA, real time conversion of YUV space to RGB space is performed. Furthermore, color thresholding algorithm is used to localize the sign in the image/video depending on the color.
Edges are the most important image/frame attributes that provide valuable information about the shape of the objects. Sobel edge detection algorithm is implemented on FPGA. After color segmentation, FPGA implementation of Sobel algorithm is used to find the edges of candidate traffic signs in real time. Later, radial symmetry based shape detection algorithm is used to determine circular
traffic signs.
Each FPGA implemented algorithm is tested by using video sequences and static images. In addition, combined implementation of color based and shape based algorithms are tested. Joint application of color and shape based algorithms are used in order to reduce search domain and the processing time of detection process.
Designing architecture on FPGA makes traffic sign detection system portable as a final product and relatively more efficient than the computer based detection systems. The resulting hardware is suitable where cost and compactness constraints are important.

DGRSVX and DMSRIC: Fortran 77 subroutines for solving continuous-time matrix algebraic Riccati equations with condition and accuracy estimatesPetkov, P. Hr., Konstantinov, M. M., Mehrmann, V. 12 September 2005 (has links) (PDF)
We present new Fortran 77 subroutines which implement the Schur method and the
matrix sign function method for the solution of the continuoustime matrix algebraic
Riccati equation on the basis of LAPACK subroutines. In order to avoid some of
the wellknown difficulties with these methods due to a loss of accuracy, we combine
the implementations with block scalings as well as condition estimates and forward
error estimates. Results of numerical experiments comparing the performance of both
methods for more than one hundred well and illconditioned Riccati equations of order
up to 150 are given. It is demonstrated that there exist several classes of examples for
which the matrix sign function approach performs more reliably and more accurately
than the Schur method. In all cases the forward error estimates allow to obtain a reliable
bound on the accuracy of the computed solution.

Automatic recognition of American sign language classifiersZafrulla, Zahoor 08 June 2015 (has links)
Automatically recognizing classifier-based grammatical structures of American Sign Language (ASL) is a challenging problem. Classifiers in ASL utilize surrogate hand shapes for people or "classes" of objects and provide information about their location, movement and appearance. In the past researchers have focused on recognition of finger spelling, isolated signs, facial expressions and interrogative words like WH-questions (e.g. Who, What, Where, and When). Challenging problems such as recognition of ASL sentences and classifier-based grammatical structures remain relatively unexplored in the field of ASL recognition.
One application of recognition of classifiers is toward creating educational games to help young deaf children acquire language skills. Previous work developed CopyCat, an educational ASL game that requires children to engage in a progressively more difficult expressive signing task as they advance through the game.
We have shown that by leveraging context we can use verification, in place of recognition, to boost machine performance for determining if the signed responses in an expressive signing task, like in the CopyCat game, are correct or incorrect. We have demonstrated that the quality of a machine verifier's ability to identify the boundary of the signs can be improved by using a novel two-pass technique that combines signed input in both forward and reverse directions. Additionally, we have shown that we can reduce CopyCat's dependency on custom manufactured hardware by using an off-the-shelf Microsoft Kinect depth camera to achieve similar verification performance. Finally, we show how we can extend our ability to recognize sign language by leveraging depth maps to develop a method using improved hand detection and hand shape classification to recognize selected classifier-based grammatical structures of ASL.

Route switching behavior among Austin commutersMotamed, Moggan 03 February 2014 (has links)
IH-35 is a major north-south interstate highway across the State of Texas. It is an
important business corridor, conveniently connecting four large Texas cities, Austin,
Dallas, Fort Worth, and San Antonio, as well as facilitating trade between Mexico and
the United States.
During construction of the SH-71/IH-35 Interchange, the Austin District of the
Texas Department of Transportation (TxDOT) has had to close the main lanes of IH-35
and re-route traffic. Three main lane closures happened during three weekends in 2011.
During those closures, a parallel route, the SH-130 toll road, was made free to travelers.
TxDOT provided both pre-trip and en-route information about the closure. They used
radio, TV, portable message sign (PMS), and dynamic message signs (DMS) to inform
commuters about the closure. To inform travelers passing through Austin about the
closure and the existing alternative (SH-130 was toll free), they even collaborated with
Dallas and San Antonio TxDOT district personnel.
However, usage of SH130 was less than anticipated, and there was significant
traffic queuing on IH-35. In this study, we tried to document the quantity of traffic that
used the alternative path during the IH-35 closure and explore options for relieving
delays on IH-35 during future closures. / text
