Recovering Intrinsic Images from a Single Image
(2002-09-01)We present an algorithm that uses multiple cues to recover shading and reflectance intrinsic images from a single image. Using both color information and a classifier trained to recognize gray-scale patterns, each image ...

Recovering Three-Dimensional Structure from Motion with Surface Reconstruction
(1991-12-01)We address the computational role that the construction of a complete surface representation may play in the recovery of 3--D structure from motion. We present a model that combines a feature--based structure--from- ...

Recovery of Three-Dimensional Objects from Single Perspective Images
(1998-03-01)Any three-dimensional wire-frame object constructed out of parallelograms can be recovered from a single perspective two-dimensional image. A procedure for performing the recovery is given.

ReCrash: Making Crashes Reproducible
(2007-11-20)It is difficult to fix a problem without being able to reproduce it.However, reproducing a problem is often difficult and time-consuming.This paper proposes a novel algorithm, ReCrash, that generatesmultiple unit tests ...

Rectangular Reinforced Concrete Beams Strengthened with CFRP Straps
(American Society of Civil EngineersJournal of Composites for Construction, 2013-07-13)Shear deficient reinforced concrete (RC) structures can be effectively strengthened using external prestressed carbon fibre reinforced polymer (CFRP) straps. Due to the presence of the external elastic straps, a strengthened ...

Recursive Functions of Symbolic Expressions and Their Computation
(1959-03-30)This memorandum is a continuation of Memo 8.

Recursive Functions of Symbolic Expressions and Their Computation by Machine
(1959-03-13)The attached paper is a description of the LISP system starting with the machine-independent system of recursive functions of symbolic expressions. This seems to be a better point of view for looking at the system than the ...

A Recursive Lagrangian Formulation of Manipulator Dynamics
(1980-06-01)An efficient Lagrangian formulation of manipulator dynamics has been developed. The efficiency derives from recurrence relations for the velocities, accelerations, and generalized forces. The number of additions and ...

Recursively invoking Linnaeus: A Taxonomy for Naming Systems
(2002-03-01)Naming is a central element of a distributed or network system design. Appropriate design choices are central. This paper explores a taxonomy of naming systems, and engineering tradeoffs as an aid to the namespace designer. ...

Redesigning the design process through interactive simulation: A case study of life-cycle engineering in jet engine conceptual design
(Inderscience, 2011-01)Many aerospace companies are currently making the transition to providing fully-integrated product-service offerings in which their products are designed from the outset with life-cycle considerations in mind. Based on ...

Redshifting of cosmological black bodies in BSBM varying-alpha theories
(APSPHYSICAL REVIEW D, 2014-12-04)We analyse the behaviour of black-body radiation in theories of electromagnetism which allow the electron charge and the fine structure constant to vary in space and time. We show that such theories can be expressed as ...

Reducing Drift in Parametric Motion Tracking
(2001-05-07)We develop a class of differential motion trackers that automatically stabilize when in finite domains. Most differ-ential trackers compute motion only relative to one previous frame, accumulating errors indefinitely. We ...

Redundancy Resolution of Manipulators through Torque Optimization
(1986-01-01)Methods for resolving kinematic redundancies of manipulators by the effect on joint torque are examined. When the generalized inverse is formulated in terms of accelerations and incorporated into the dynamics, the ...

Redundant Sensors for Mobile Robot Navigation
(1985-09-01)Redundant sensors are needed on a mobile robot so that the accuracy with which it perceives its surroundings can be increased. Sonar and infrared sensors are used here in tandem, each compensating for deficiencies in ...

REED: Robust, Efficient Filtering and Event Detection in Sensor Networks
(2004-03-22)This paper presents an algorithm for handling many types of filters insensor networks that cannot be expressed using a simple predicate.Specifically, the action of the filter may be predicated on sensor produceddata where ...

REEX: A CONVERT Program to Realize the McNaughton-Yamada Analysis Algorithm
(1968-01-01)REEX is a CONVERT program, realized in the CTSS-LISP of Project Mac, for carrying out the McNaughton-Yamada analysis algorithm, whereby a regular expression is found describing the words accepted by a finite state machine ...

Refactoring for parameterizing Java classes
(2006-09-05)Type safety and expressiveness of many existing Java libraries and theirclient applications would improve, if the libraries were upgraded to definegeneric classes. Efficient and accurate tools exist to assist clientapplications ...

Refactoring learning management systems for multi-device use in developing countries
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2015)Although learning management systems (LMSs) have been widely adopted by universities in developing countries, their potential to support students' learning has not been fully exploited due to several factors. Some of the ...

Refactoring Sequential Java Code for Concurrency via Concurrent Libraries
(2008-09-30)Parallelizing existing sequential programs to run efficiently on multicores is hard. The Java 5 packagejava.util.concurrent (j.u.c.) supports writing concurrent programs: much of the complexity of writing threads-safe and ...

Reflectance Map Techniques for Analyzing Surface Defects in Metal Castings
(1978-06-01)This report explores the relation between image intensity and object shape. It is shown that image intensity is related to surface orientation and that a variation in image intensity is related to surface curvature. ...
