In this paper we use a combination of techniques to detect fire in video data. First, the algorithm locates regions of the video where there is movement. From these regions firecolored pixels are extracted using a perceptron. Lastly, we use dynamic texture analysis to confirm that these moving, fire-colored regions have the temporal and motion characteristics of fire.

This paper proposes a simple factorization principle that can be used efficiently and effectively to derive the vector generating function of the queue length at an arbitrary time of the BMAP/G/1/ queueing systems under variable service speed. We first prove the factorization property. Then we provide moments formula. Lastly we present some applications of the factorization principle.

In this paper, we survey the state of research on Identity Based Blind Signature. We start from reviewing the basic concepts of identity based encryption and blind signature schemes and subsequently review the framework of ID-based blind signature, and classification of ID-based blind signature. Lastly, we discuss the applications of ID-based blind signature. Keywords— Identity Based Encryption...

This chapter gives an overview over recovery guarantees for total variation minimization in compressed sensing for different measurement scenarios. In addition to summarizing the results in the area, we illustrate why an approach that is common for synthesis sparse signals fails and different techniques are necessary. Lastly, we discuss a generalizations of recent results for Gaussian measureme...

In this paper we provide a detailed overview of the field of software restructuring and refactoring from a formal as well as a from a practical point of view. After summarizing refactoring’s current applications and tool support, we discuss the current research on refactoring in a number of essential research questions. Lastly, we highlight the key directions in which refactoring research is mo...
