Differential Forms and Applications
(2011-12-06)This project deals mainly with Differential Forms on smooth Riemannian manifolds and their applications through the properties of their classical Differential and Integral Operators. The calculus of Differential Forms ...
-
Evolution Equations and Applications
(2011-12-06)This project concerns Evolution Equations in Banach spaces and lies at the interface between Functional Analysis, Dynamical Systems, Modeling Theory and Natural Sciences. Evolution Equations include Partial Di erential ...
-
Sobolev Spaces and Linear Elliptic Partial Differential Equations
(2011-12-06)The cardinal goal to the study of theory of Partial Differential Equations (PDEs) is to insure or find out properties of solutions of PDE that are not directly at- tainable by direct analytical means. Certain function ...

Spectral Theory of Compact Linear Operators and Applications
(2011-12-08)This Project primarily falls into the field of Linear Functional Analysis and its Applications to Eigenvalue problems. It concerns the study of Compact Lin- ear Operators (i.e., bounded linear operators which map the ...
-
The Mountain Pass Theorem and Applications
(2010-12-06)This project lies at the interface between Nonlinear Functional Anal- ysis, unconstrained Optimization and Critical point theory. It concerns mainly the Ambrosetti-Rabinowitz's Mountain Pass Theorem which is a min-max ...
-
Isoperimetric Variational Techniques and Applications
(2010-12-06)This project is at the interface between Nonlinear Functional Analysis, Con- vex Analysis and Di erential Equations. It concerns one of the most powerful methods often used to solve optimization problems with constraints; ...
-
Floquet Theory and Applications
(2010-12-07)This project is at the interface between Analysis, Natural Sciences and Modeling Theory. It deals with Floquet Theory (also re ered to as Floquet-Lyapunov theory) which is the main tool of the theory of periodic ordinary ...

Semigroups Of Linear Operators And Application To Differential Equations
(2009-12-04)This work concerns one of the most important tools to solve well-posed problems in the the- ory of evolution equations (e.g di usion equation, wave equations, ...) and in the theory of stochastic process, namely the ...

Controllability And Stabilizability Of Linear Systems In Hilbert Spaces
(2010-12-06)Questions about controllability and stability arise in almost every dynamical system problem. As a result, controllability and stability are one of the most extensively studied subjects in system theory. A departure point ...

Guaranteeing Spoof-Resilient Multi-Robot Networks
(July 2015)Multi-robot networks use wireless communication to provide wide-ranging services such as aerial surveillance and unmanned delivery. However, effective coordination between multiple robots requires trust, making them ...
-
Value-Deviation-Bounded Serial Data Encoding for Energy-Efficient Approximate Communication
(2015-06-04)Transferring data between ICs accounts for a growing proportion of system power in wearable and mobile systems. Reducing signal transitions reduces the dynamic power dissipated in this data transfer, but traditional ...

Homological stability for spaces of embedded surfaces
(Mathematical Sciences PublisherGeometry and Topology, 2017-05-10)© 2017, Mathematical Sciences Publishers. All rights reserved.We study the space of oriented genus-g subsurfaces of a fixed manifold M and, in particular, its homological properties. We construct a “scanning map” which ...

An Analysis of Patch Plausibility and Correctness for Generate-And-Validate Patch Generation Systems
(2015-05-29)We analyze reported patches for three existing generate-and-validate patch generation systems (GenProg, RSRepair, and AE). The basic principle behind generate-and-validate systems is to accept only plausible patches that ...
-
Designing an architecture for secure sharing of personal health records : a case of developing countries
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2014)While there has been an increase in the design and development of Personal Health Record (PHR) systems in the developed world, little has been done to explore the utility of these systems in the developing world. Despite ...

Volumetric cloud generation using a Chinese brush calligraphy style
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2014)Clouds are an important feature of any real or simulated environment in which the sky is visible. Their amorphous, ever-changing and illuminated features make the sky vivid and beautiful. However, these features increase ...
-
Semi-automatic matching of semi-structured data updates
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2014)Data matching, also referred to as data linkage or field matching, is a technique used to combine multiple data sources into one data set. Data matching is used for data integration in a number of sectors and industries; ...

Multi-layered security in the Internet of the Things
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2014)It is well discussed and understood that there is still a need for suitable security for the Internet of Things. It is however still not clear how existing or emerging security paradigms can be effectively applied to a ...

Prophet: Automatic Patch Generation via Learning from Successful Human Patches
(2015-05-26)We present Prophet, a novel patch generation system that learns a probabilistic model over candidate patches from a large code database that contains many past successful human patches. It defines the probabilistic model ...
-
Automatic Discovery and Patching of Buffer and Integer Overflow Errors
(2015-05-26)We present Targeted Automatic Patching (TAP), an automatic buffer and integer overflow discovery and patching system. Starting with an application and a seed input that the application processes correctly, TAP dynamically ...
