This paper presents the concept of the Spring framework which is widely used in making enterprise wide Applications along with other frameworks. Spring framework insists that ordinary java beans can be used with slight modifications to them. This framework is used within J2EE architecture to make it easier to develop large scale java applications. This paper presents the architecture overview o...

this study was undertaken to investigate the effect of long-term reduced tillage on grain yield, grain quality, and weed infestation of spring wheat. the experimental variables were three tillage systems: (a) conventional tillage (ct): shallow ploughing (10-12 cm) and harrowing after harvest of the previous crop, ploughing (25-30 cm) in the autumn; (b) reduced tillage (rt): only a cultivator (1...

Trotting and hopping animals use muscles, tendons and ligaments to store and return elastic energy as they bounce along the ground. We examine how the musculoskeletal spring system operates at different speeds and in animals of different sizes. We model trotting and hopping as a simple spring-mass system which consists of a leg spring and a mass. We find that the stiffness of the leg spring (k(...

Commercially available prosthetic hands are simple grippers with one or two degrees of freedom; these pinch type devices have two rigid fingers in opposition to a rigid thumb. This paper focuses on an innovative approach for the design of a myoelectric prosthetic hand. The new prosthesis features underactuated mechanisms in order to achieve a natural grasping behavior and a good distribution of...

In our investigation, we used Hamiltonian dynamics to model two different spring-pendulum systems in MATLAB. First, we confirmed that chaotic motion is possible in the classic single spring-pendulum system in two dimensions and without damping. Next, we modified the system by attaching the mass to two springs (Figure 1b) and tested to see how the dynamics change with the addition of this second...

In the Multimedia and Mobile Agent Research Laboratory an underway work is conducted toward combining management policies and Mobile Agents in the area of collaborative applications. The goal is to have a collaborative system thoroughly based on agents and highly flexible and dynamically manageable through multi-level policies. Towards this objective, we have designed a global framework to supp...

This report makes a case for the need to examine the methodological foundations of AI. Many aspects of AI have not yet developed to a point of general agreement. The goals of AI work, the methods for acheiving these goals, the presentation of results, and the assessment of claims are all highly contentious issues. All aspects of AI methodology are subject to debate The Workshop on the Foundatio...

Problem 1. Infinite Products and Coproducts in Ab. We have seen that finite products and coproducts agree in Ab. However, the same is not true for infinite products and coproducts. Let I be a set and let {Ai}i∈I be a family of abelian groups, each equal to some fixed group A. (a) Show that the set AI := HomSet(I, A) is an abelian group. Furthermore, show that we can think of this group as the i...

In this paper we discuss numerical strategies to find periodic orbits of nonlinear dynamic system. These orbits shall be open-loop stable and robust with respect to bounded disturbances. For this aim, we review and extend existing techniques from the field of reachability analysis and ellipsoidal calculus to compute robust positive invariant tubes for nonlinear dynamic systems. We suggest a con...
