Erp Implementation Decisions Under The Condition Of (A)-Symmetric Information: An Agency Approach., L. Wang, S. Poelmans, K. Milis May 2012

Erp Implementation Decisions Under The Condition Of (A)-Symmetric Information: An Agency Approach., L. Wang, S. Poelmans, K. Milis

Applied Mathematics & Information Sciences

The optimization investment policy decision of an ERP implementation has been analysed under symmetric and asymmetric information conditions. For both conditions, ERP implementation options’ decision optimizing models have been developed. In these models, both clients and vendors try to pursue their own benefits. Based upon the principal-agent theory, the models show to what extent a principal (a client) needs to pay more to an agent (a vendor) in a context of asymmetric information. For the client, it is important to understand the extra costs to be able to adopt effective strategies to stimulate a vendor to perform an optimal implementation …

A Second-Order Differentiable Smoothing Approximation Lower Order Exact Penalty Function, Wenling Zhao, Ranran Li May 2012

A Second-Order Differentiable Smoothing Approximation Lower Order Exact Penalty Function, Wenling Zhao, Ranran Li

Applied Mathematics & Information Sciences

In this paper, we give a smoothing approximation to the lower order exact penalty functions for inequality-constrained optimization problems. Error estimations are obtained among the optimal objective function values of the smoothed penalty problem, of the nonsmooth penalty problem and of the original optimization problem. An algorithm based on the smoothed penalty function is presented, which is shown to be globally convergent under some mild conditions. Numerical examples are given to illustrate the effectiveness of the present smoothing method.

The Principle Of Superposition For Waves: The Amplitude And Phase Modulation Phenomena, L. M. Arevalo Aguilar, C. Robledo-Sanchez, M. L. Arroyo Carrasco, M. M. M´Endez Otero

Applied Mathematics & Information Sciences

In this paper we will argue that the superposition of waves can be calculated in a simple way. We show, using the Gauss’s method to sum an arithmetic sequence, how it is possible to construct the superposition of waves - with different frequencies - in a simple conceptual way. By this method we arrive to the usual result where we can express the superposition of waves as the product of factors, one of them with a cosine function where the cosine’s argument is the average frequency. Most important, we will show that the superposition of waves with slightly different frequencies …

A Mathematical Characterization Of System Design And Modeling, Xibin Zhao May 2012

A Mathematical Characterization Of System Design And Modeling, Xibin Zhao

Applied Mathematics & Information Sciences

SystemC is an emerging standard hardware description language for system-level modeling and design. Formal semantics could give its meaning in a mathematically rigorous and unambiguous way. In this paper, we formalize SystemC both from processes and simulation environment by process algebra, which enables that deduction and verification of the whole simulation procedure are in an integrated and convenient manner. Meanwhile, in order to accommodate event-driven and concurrent properties of SystemC, we adopt event structure characterized by true concurrency, as semantic model of both SystemC and its simulation environment for denotational semantics and operational semantics, as well as demonstrate the correspondence …

We develop an extremely simple class for constructing the worst case data set for the partition based selection algorithm. The general method works against any implementation of partition based selection algorithm that satisfies certain very mild and realistic assumptions. Computational results ascertain that the techniques developed are not only of theoretical interest, but also may actually lead to the worst case …

In the segmentation, foreground is firstly separated by simple background subtraction method. And then, the Bayes classifier is introduced to eliminate the misclassifications points to improve the segmentation …

Unveiling Of Geometric Generation Of Composite Numbers Exactly And Completely, Stein E. Johansen May 2012

Unveiling Of Geometric Generation Of Composite Numbers Exactly And Completely, Stein E. Johansen

Applied Mathematics & Information Sciences

We present a certain geometrical interpretation of the natural numbers, where these numbers appear as joint products of 5- and 3-multiples located at specified positions in a revolving chamber. Numbers without factors 2, 3 or 5 appear at one of eight such positions, after a specified amount of rotations of the chamber. Our approach determines the sets of rotations constituting primes at the respective eight positions, as the complements of the sets of rotations constituting composite numbers at the respective eight positions. These sets of rotations constituting composite numbers are exhibited in strict rotation regularities from a basic 8£8-matrix of …


Rt-Dbp: A Multi-Criteria Priority Assignment Scheme For Real-Time Tasks Scheduling, L. Baccouche, H. Eleuch May 2012

Rt-Dbp: A Multi-Criteria Priority Assignment Scheme For Real-Time Tasks Scheduling, L. Baccouche, H. Eleuch

Applied Mathematics & Information Sciences

Several real-time applications, such as E-commerce, multimedia and process control are subject to multiple criteria scheduling problems. In such systems service differentiation and quality of service (QoS) guarantees are necessary. Often the multi-class task model can be associated to multiple (m,k)-firm constraints indicating the degree of missed deadlines that the system can tolerate for each class. In this paper we study (m,k)-firm task scheduling and we propose a priority assignment scheme that takes into consideration various scheduling constraints. The approach is validated through simulation under various configuration patterns.

Post-Quantum Secure Hybrid Signcryption From Lattice Assumption, Fenghe Wang, Yupu Hu, Chunxiao Wang

Applied Mathematics & Information Sciences

Motivated by the demand to have secure signcryption scheme, even in quantum era, the concept of signcryption tag-KEM (key encapsulation machine) is extended to lattice cryptography in this paper. A lattice-based hybrid signcryption scheme is proposed by building a lattice-based signcryption tag-KEM. Based on the hardness of the learning with errors problem and the short integer solution problem, the proposed hybrid signcryption is provable secure in the random oracle model. Furthermore, according to the quantum intractability assumption about lattice problem, the proposed hybrid signcryption scheme is secure even on quantum computers.


Optimal Attack Strategies In A Dynamic Botnet Defense Model, Y. Shang Jan 2012

Optimal Attack Strategies In A Dynamic Botnet Defense Model, Y. Shang

Applied Mathematics & Information Sciences

Since the number of compromised computers, or botnet, continues to grow, the cyber security problem has become increasingly important and challenging to both academic researchers and industry practitioners. A respect to combat botnet propagation is to understand the attacker’s behaviors based on the whole operation of a system that can be modeled with population models used in epidemiological studies. In this paper, we treat the interaction between the botnet herder and the defender group as a modified SIS epidemic model with external entrance and allowing computers of undetected states. Based on optimal control theory, we derive the optimal strategy of …


Two-Mode Ring Lasers: Stable, Instable And Irregular Behaviors In Coupled Lasers Logistic Equations, Muhammad Abdul, Farhan Saif Jan 2012

Two-Mode Ring Lasers: Stable, Instable And Irregular Behaviors In Coupled Lasers Logistic Equations, Muhammad Abdul, Farhan Saif

Applied Mathematics & Information Sciences

We have analyzed two-mode ring coupled laser equations, after transforming them to the corresponding two dimensional coupled logistic equations. In our numerical experiment we find that for selected range of the three controlling parameters, chaotic pattern may emerge out of an infinite sequence of period-doubling bifurcations. However, there exists large regions of controlling parameter space where the approach to irregular behavior appears to be consistent with the Newhouse-Ruelle-Takens scenario, as evident by the appearance of two characteristics frequencies. As the ratio of controlling frequencies is varied, by changing the controlling parameters, phase locking periodic and quasi-periodic motions are observed on …

Design Of Dynamic Sliding Mode Controller To Roelastic Systems, Chieh-Li Chen, Chung-Wei Chang, Her-Terng Yau

Applied Mathematics & Information Sciences

It is well known that for the model with a single trailing-edge control surface, trajectory control of either the plunge displacement or the pitch angle (but not of both) can be achieve by the controller design and there exist internal dynamics describing the residual motion in aeroelastic closed-loop systems. The internal dynamics of aeroelastic depend on the model parameters including the free stream velocity and spring constant. Motivated by the limited effectives of using single control surface, improvements in control of limit-cycle oscillation by using leadingand trailing-edge control surface are investigated. Moreover, two control surfaces provide flexibility in shaping both …


Semiring Orders In A Semiring, Jeong Soon Han, Hee Sik Kim, J. Neggers Jan 2012

Semiring Orders In A Semiring, Jeong Soon Han, Hee Sik Kim, J. Neggers

Applied Mathematics & Information Sciences

Given a semiring it is possible to associate a variety of partial orders with it in quite natural ways, connected with both its additive and its multiplicative structures. These partial orders are related among themselves in an interesting manner is no surprise therefore. Given particular types of semirings, e.g., commutative semirings, these relationships become even more strict. Finally, in terms of the arithmetic of semirings in general or of some special type the fact that certain pairs of elements are comparable in one of these orders may have computable and interesting consequences also. It is the purpose of this paper …
