One of the bio-sensing mechanisms is mechanical. Rather than measuring shift in resonance frequency, we adopt to measure the change in spring constant due to adsorption, as one of the fundamental sensing mechanism. This study explains  determination of spring constant of a surface functionalized micro machined micro cantilever, which resonates in a trapezoidal cavity-on Silicon wafer, with the ...

Besides finite element method, mass-spring systems are widely used in Computer Graphics. It is indubitably the simplest and most intuitive deformable model. This discrete model allows to perform interactive deformations with ease and to handle complex interactions. Thus, it is perfectly adapted to generate visually plausible animations. However, a drawback of this simple formulation is the rela...

Mass-Spring systems are used widely to implement animation of deformable objects. We have developed a simple mass-spring system to animate a character based on physics. The reason we adopt a mass-spring system is simply we wanted more realism than Free Form Deformation (FFD) techniques can offer, as modeling physical processes. Also, this technique is preferred over Finite Element Methods (FEM)...

This experiment was set up to explore the physics of a bungee jump. The goal of the experiment was to develop a method to isolated variables of a model bungee system as to gain insight the relationships between different parts of the bungee system as a whole. Specifically our experiment aimed to determine an appropriate way to determine the stiffness of a bungee cord. One of the most important ...

Due to the high strength-to-weight ratio of fibre reinforced polymers (FRPs), human-induced vibration problematic remains as a subject be fully comprehended in order extend use composites Bridge Engineering. Thus, this paper studies an ultra-lightweight FRP footbridge, which presents excessive vertical vibrations when fourth harmonic walking pedestrian is synchronised with structure’s fundament...

Models of skeletal muscle based on its response to sinusoidal stimulation have been in use since the late 1960s. In these methods, cyclic excitation at varying frequencies is used to determine force or muscle length amplitude and phase as functions of excitation frequency. These functions can then be approximated by models consisting of combinations of poles and zeros and pure time delays witho...

In this paper we describe a procedure for parameters identification using an algebraic identification method for a continuous time constant linear system. We make a specific application in the determination of the parameters mass-spring-damper system. The method is suitable for simultaneously identifying, both, the spring constant and the damping coefficient. It is found that the proposed metho...

Mass-spring systems are considered the simplest and most intuitive of all deformable models. They are computationally efficient, and can handle large deformations with ease. But they suffer several intrinsic limitations like the difficulties in controlling anisotropy, springs functions para-meterization and enforcing volume preservation. As part of this project, a modified mass-spring system th...
