The Service-oriented architecture (SOA) paradigm has been gaining momentum over the last few years. Although the banking industry has often been mentioned as an early adaptor of service-oriented technologies, there is still a lack of knowledge concerning bank requirements on IT architectures and whether an SOA is suited to meet them. In this paper, we present the results from an empirical study...

We present improvements to algorithms for efficient exponentiation. The fractional window technique is a generalization of the sliding window and window NAF approach; it can be used to improve performance in devices with limited storage. Window NAF splitting is an efficient technique for exponentiation with precomputation for fixed bases in groups where inversion is easy (e.g. elliptic curves).

Detecting information trends in online social networks is an important problem that has attracted the attention of both the industry and the research community in recent years. Global trends, information items that are trendy in the entire social network, can be detected using existing data streams techniques. However, detecting global trends is only the first step in understanding online socia...

Projecting the fates of populations under climate change is one of global change biology's foremost challenges. Here, we seek to identify the contributions that temperature-mediated local adaptation and plasticity make to spatial variation in nesting phenology, a phenotypic trait showing strong responses to warming. We apply a mixed modeling framework to a Britain-wide spatiotemporal dataset co...

We present new algorithms for the sliding window Lempel-Ziv (LZ77) problem and the approximate rightmost LZ77 parsing problem. Our main result is a new and surprisingly simple algorithm that computes the sliding window LZ77 parse in O(w) space and either O(n) expected time or O(n log logw + z log log σ) deterministic time. Here, w is the window size, n is the size of the input string, z is the ...

The ideal real time personal authentication system should be fast and accurate to automatically identify a person’s identity. In this paper, we have proposed a palmprint based biometric authentication method with improvement in time and accuracy, so as to make it a real time palmprint authentication system. Several edge detection methods, wavelet transform, phase congruency etc. are available t...

Authentication time is the main and important part of the authentication system. Normally the response time should be fast but as the number of persons in the database increases, there is probability of more response time taken for authentication. The need of fast authentication system arises so that authentication time (matching time) is very less. This paper proposes a sliding window approach...

Product Markets and Paychecks: Deregulation's Effect on the Compensation Structure in Banking This paper asks how deregulation intended to promote competition in the commercial banking industry affected the compensation structure for banking employees. Using establishment-based data from the Employment Cost Index Survey of the U.S. Bureau of Labor Statistics, I obtain measures of the level and ...

Program analysis plays an important role in finding software flaws. Due to dynamic language features like late binding, there are many program analysis problems for which one could not assume a prior program control flow, e.g., Java points-to analysis, the disassembly of binary codes with indirect jumps, etc. In this work, we give a general formalization of such kind of on-the-fly interprocedur...
