On the Pricing Method of the Non-performing Loan Securitization

This paper analyzed in depth the difference between the pricing of non- performing loan （NPL） securitization and that of ordinary asset securitization. It has explained the pricing thought and method of non-performing loan backed securities in connection with the particularity and complexity of non-performing loan and finally proposed some key problems which need to be emphasized during the pricing practice of non-performing loan backed securitization.

Efficient Calculation of the Radar Cross Section at the Interior Resonance by the Inverse Power Method

It is well known that the incorrect results will be given using either the electric or magnetic field integral equation to calculate the radar cross section (RCS) of a closed body at the interior resonance. In this paper, an effective iterative technique is used to correct the calculated surface current density from the electric field integral equation. The radar cross section is computed for an infinite conducting circular cylinder at the interior resonance, and the obtained results are     

Application of the Season Time Series Model to Forecast the Rainfall in the Area of Well Irrigation Rice in the Sanjiang Plain

The area of well irrigation rice became more and more, so the crisis of groundwater appeared. Making the most of rainfall is an availability method in water saving irrigation, increasing water temperature and raising yield. Just based on this, through applying the theory of season random time series, according to the data of average monthly rainfall (1981 - 1999), the authors build up the forecasting model in the area of well irrigation rice in the Sanjiang Plain. Through contrasting with practical value, the model has good effect.So, it can be used in water irrigation management.     

New method of improving the security of the hyperchaotic cryptosystem

He thinks thatone possibility to i mprove the privacy of chaotic en-codingis to use (very) high di mensional chaotic at-tractors for encrypting a given message[2].Firstly, based on the active-passive decomposi-tion method, he decomposed a hyperchaotic systeminto transmitter and receiverx.1=-x2+ax1x.m= xm-1-xm+1, m =2,…,M-1x.M=ε+bxM( xM-1-d) (1)wherea=0·29, b=4, d=2,ε=0·1 .

On the Pricing Problem of the Risk Assets Based on the Principle of Unallowable Essential Arbitrage

Most results of the traditional finance theory were based on the principle of no arbitrage opportunity exists. However, this condition is so weak that it can be easily satisfied, thus we introduce the principle of unallowable essential arbitrage to replace the traditional principle of no arbitrage opportunity exists as a standard for the financial market being perfect.     

Goal-Programming Model Based on the Utility Function of the Decision-maker

1 1ntroductionDeveloped by Charnes and Cooper['J in l960s, Goal-programming (GP) is a new branch ofOR for multiple--criteria decision-making problem. Because GP can be used to solve theproblems with several objectives which are generally in conflict, it has been widely appliedto quite different fields such as accounting, finance, marking, human resources,production, transportation, plant location, agriculture, etc.Considering some weakness of GP in the practical use, this paper presented t…     

On the Gracefulness of the Digraphs n·Cm＊

A digraph D（V, E） is said to be graceful if there exists an injection f ： V（G） →{0, 1,... , ｜E｜} such that the induced function f＇ ： E（G） --~ {1, 2,… , ｜E｜} which is defined by f＇ （u, v） = [f（v） - f（u）] （rood ｜E｜＋ 1） for every directed edge （u, v） is a bijection. Here, f is called a graceful labeling （graceful numbering） of D（V, E）, while f＇ is called the induced edge＇s graceful labeling of D. In this paper we discuss the gracefulness of the digraph n- Cm and prove that n. Cm is a graceful digraph for m = 15, 17 and even

On the Usefulness of the Ackoff–Gharajedaghi Model of System Types for the Design of Business Systems

The Ackoff–Gharajedaghi Model of System Types distinguishes 3 fundamental empirical systems: deterministic, animate, and social, with regard to their purpose. It has been formulated as a meta-model to support understanding, selection, and formulation of management models and theories. It is argued here that this model is also valuable for the interpretation and design of actual, empirical business systems. A study of a malfunctioning business is presented and interpreted with the Ackoff–Gharajedaghi Model, which supports this argument. Additionally, the study shows a pragmatic value of the proposed Imperative of Goals Alignment for the design of business systems, which is an operationalization of the Ackoff–Gharajedaghi Model. Furthermore, the investigation illustrates the importance of clear goals and incentives in business design; and it supports the thesis of the Ackoff–Gharajedaghi Model that management models and theories, founded upon empirical observations of deterministic and animate systems, impose limitations on the design of business systems.
