ABSTRACT
Human-Structure Interaction in Cantilever Grandstands
There is a risk that excessive vibration in long span cantilever grandstands can betriggered by the spectators synchronising their jumps to the music played. If thejumping frequeny excites a resonance of the grandstand, large force could begenerated. This thesis studies human-structure interaction in cantilever grandstands,with emphasis on modelling the passive and jumping crowds, and analysing theresponse of a single degree-of-freedom (SDOF) structural ....etc

Today, the technology meant for manufacturing different commodities in various fields are considered to be very expensive, time consuming and cannot be entirely utilized. Think about a technology with which man can create any kind of commodity in lesser timer, with lesser money and which is very efficient.Biomolecular Nanotechnology means molecular manufacturing or, simply building things from one atom or molecule at a time with programmed nanoscopic robot arms.Biomolecular Nanotechnology is about rearranging atoms whichever way we want. The us ....etc

1. ABSTRACT
Cracks present in machine parts affect their vibrational behaviour like the fundamental frequency and the resonance. This case is usual in machine parts subjected to fatigue type of loading. In this paper, the resonance response of a cracked cantilever beam has been studied based on fracture mechanics quantities like strain energy release rate, stress intensity factor and compliance. The vibration behaviour of a cantilever beam with cracks at fixed end and at the mid span has been analyzed ....etc

Nanotechnology will help bring in strategically important driving force to future electronics. Intensive R & D on nanotechnology for chip applications is being driven from two distinct directions: 1) to sustain and enhance the great technology momentum established in decades by silicon ICs and 2) to explore revolutionary technologies in the ?beyond-silicon? era. Nanotechnology-enabled chip systems offer merits such as energy-efficiency, scalability, surface sensitivity, tunable properties, and low fabrication cost, all in tune with the futur ....etc

CANTILEVER TECHNIQUE IN NANOTECHNOLOGY
What is a cantilever ??
A cantilever is a beam supported on only one end. The beam carries the load to the support where it is resisted by moment and shear stress
Cantilevered beams are the most ubiquitous structures in the field of micro electromechanical systems (MEMS
The MEMS cantilevers are commonly made as unimorphs or bimorphs:
 UNIMORPH: A unimorph is a cantilever that consists of one activ ....etc

Definition
Nanotechnology is defined as fabrication of devices with atomic or molecular scale precision. Devices with minimum feature sizes less than 100 nanometers (nm) are considered to be products of nanotechnology. A nanometer is one billionth of a meter (10-9 m) and is the unit of length that is generally most appropriate for describing the size of single molecules. The nanoscale marks the nebulous boundary between the classical and quantum mechanical worlds; thus, realization of nanotechnology promises to bring revolutionary capabilities ....etc

Imagine a supercomputer no bigger than a human cell. Imagine a four-person, surface-to-orbit spacecraft no larger or more expensive than the family car. Imagine attaining immortality by drinking a medicine. These are just a few products expected from Nanotechnology.

Nanotechnology is molecular manufacturing or, more simply, building things one atom or molecule at a time with programmed nanoscopic robot arms; Nanotechnology proposes the construction of novel molecular devices possessing extraordinary properties. The trick is to ma ....etc
