Thirty years ago Bourrely-Soffer-Wu (BSW) investigated an impact picture description of p−p and p̄−p elastic scattering with success. For this anniversary, a short review of the main features of this picture will be presented with its evolution over the years. The future experiments at the LHC collider will provide decisive tests for the impact picture at high energy. In the year 1978, BSW propo...

This paper is concerned with multidimensional exponential fitting modified Runge-Kutta-Nyström (MEFMRKN) methods for the system of oscillatory second-order differential equations q ′′(t) +Mq(t) = f (q(t)), where M is a d × d symmetric and positive semi-definite matrix and f (q) is the negative gradient of a potential scalar U(q). We formulate MEFMRKN methods and show clearly the relationship be...

bag of related financial instruments to make profits by exploiting their relations. One important feature of pairs trading is that it is market-neutral, which is particularly appealing in the current volatile and unpredictable macro-economic environments. In this project, we will use the spread model, the O-U meanreverting model, and SVM to build a trading strategy and apply the strategy to GOO...

This paper provides a new explanation for the relationship between firm scope, agent's effort and corporate risk. I set up a moral hazard in teams model with multiple agents and departments under the assumption that both the principal and the agents are protected by limited liability. Each agent exerts effort to reduce the probability of loss of his department. The two-sided limited liability a...

For the cellular networks to effectively cover a terrain or environment, accurate prediction of the coverage of the radio frequency signal is highly needed. Wave propagation models are essential and very important tools for determining the wave propagation characteristics for a particular environment. Path loss predictions are therefore required for the coverage planning, determination of multi...

In this paper, we re-visit the inference problem for interval identi…ed parameters originally studied in Imbens and Manski (2004) and later extended in Stoye (2007). We establish a new con…dence interval that is asymptotically valid under the same assumptions as in Stoye (2007). Like the con…dence interval of Stoye (2007), our new con…dence interval extends that of Imbens and Manski (2004) to a...

Due to an error during production, the Figure 7b in the published paper [1] was incorrect. The correct figure is as follows: Figure 7. (a) Thickness of the silver film (b) reflectivity for 532 nm wavelength light versus number of laser scans (symbols: experimental data, lines: fitted curves). We apologize for any inconvenience caused to readers or authors by these changes. The article will be u...

In this paper, a generic methodology based on swarm algorithms using Artificial Bee Colony (ABC) algorithm is proposed for combined cost and weight optimization of laminated composite structures. Two approaches, namely Vector Evaluated Design Optimization (VEDO) and Objective Switching Design Optimization (OSDO), have been used for solving constrained multi-objective optimization problems. The ...

In this paper, we have used numerical simulation to study failure of adhesive joints in composite plates. To determine the failure load, adhesive joints are subjected to different types of loading and gradual failure of the joint is studied using the finite element method. The composite material failure theory is implemented into the FEM software. Also different geometries for the joint edge ar...
