Confidentiality is maybe the most popular security property to be formally or informally verified. Noninterference is a baseline security policy to formalize confidentiality of secret information manipulated by a program. Many static analyses have been developed for the verification of noninterference. In contrast to those static analyses, this paper considers the run-time verification of the r...

An algorithm is presented which extracts features from a time series of Flash LADAR images without a-priori knowledge of the surrounding environment. Flash LADAR utilizes laser ranging to acquire 3D information in the object space, which may be utilized to reconstruct the sensor environment. The extracted features are tested to identify motion artifacts and separate entities into static and non...

The aim of this paper is to investigate geometrically nonlinear static analysis of axially functionally graded cantilever beam subjected to transversal non follower load. The considered problem is solved by finite element method with total Lagrangian kinematic approach. The material properties of the beam vary along the longitudinal direction according to the power law function. The finite elem...

Sometimes the need for non-circular ducts arises in many heat transfer applications because of lower pressure drop of non-circular cross section such as square duct compared to circular tube, particularly in compact heat. But square cross section has poor heat transfer performance and it is expected that using a nanofluid as a new heat transfer media may improve the heat transfer performance of...

With the emergence of large-volume and high-speed streaming data, mining data streams has become a focus of increasing interests. The major new challenges in streaming data mining are as follows: (1) since streams may flow in and out indefinitely and in fast speed, it is usually expected that a stream mining process can only scan a data stream once; and (2) since the characteristics of the data...

Introduction The main purpose of this work is the static detection of orphan messages in actor based languages. An orphan is a message which may not be handled by its target in some execution paths. Two kinds of orphan messages may be encountered : safety ones and liveness ones. Safety orphans occur when all target behaviors on a given execution path do not know how to handle the message. Liven...

We study an extreme non-static limit of 2+1-dimensional QED obtained by making a dimensional reduction so that all fields are spatially uniform but time dependent. This dimensional reduction leads to a 0+1-dimensional field theory that inherits many of the features of the 2+1-dimensional model, such as Chern-Simons terms, time-reversal violation, an analogue of parity violation, and global U(2)...

We propose a size analysis procedure that combines testing and type checking to automatically obtain static output-on-input size dependencies for first-order functions. Attention is restricted to functions for which the size of the result is strictly polynomial, not necessarily monotonous, in the sizes of the arguments. To infer a size dependency, the procedure generates hypotheses for increasi...

Recently, a new type of BPS vortex was found in U(N) gauge theories. This is called non-Abelian vortex and carries the non-Abelian charge CP = SU(N)C+F SU(N−1)C+F×U(1)C+F . Readers can find good reviews in and references of related works therein. In this talk we are interested in studying interactions between non-Abelian vortices which are non-BPS. The nonBPS vortices are more natural than BPS ...
