Fear is the path to the dark side. Fear leads to anger. Anger leads to hate. Hate leads to suffering."

Things turn out best for the people who make the best out of the way things turn out

The important thing is not being afraid to take a chance. Remember, the greatest failure is to not try.

Once you find something you love to do, be the best at doing it.

We cannot hold a torch to light another persons path without brightening our own.

I can accept failure, everyone fails at something. But I cant accept not trying.

The best way to escape from the problem is solve it.

Determination is the strength that will enable you to pass the barrier of useless thoughts in order to

create, positive thoughts and to be successful in whatever you wish.

It comes from within and its partner is patience. Patience teaches you not to push but rather to waitand appreciate the game of life instead, knowing that nothing remains the same, and everything will

change at some point.

Short for commercialoff-the-shelf, an adjective that describes software or hardware products that

are ready-made and available for sale to the general public. For example , Microsoft Office is a COTS

product that is a packaged software solution for businesses. COTS products are designed to be

implemented easily into existing systems without the need for customization

y ACOTS (commercial off-the-shelf) product is one that is used "as-is." COTS products aredesigned to be easily installed and to interoperate with existing system components. Almost

all software bought by the average computer user fits into the COTS category: operating

systems, office product suites, word processing, and e-mail programs are among the myriad

examples. One of the major advantages of COTS software, which is mass-produced, is its

relatively low cost.

y AMOTS (either modified or modifiable off-the-shelf, or military off-the-shelf, depending onthe context) product

y Linux licensing and support is typically a COTS product whose source code can be modified.The product may be customized by the purchaser, by the vendor, or by another party to

meet the requirements of the customer. In the military context, MOTS refers to an off-the-

shelf product that is developed or customized by a commercial vendor to respond to specific

military requirements. Because a MOTS product is adapted for a specific purpose , it can be

purchased and used immediately. However, since MOTS software specifications are written

by external sources, government agencies are sometimes leery of these products, because

they fear that future changes to the product will not be in their control.

y AGOTS (government off-the-shelf) product is typically developed by the technical staff ofthe government agency for which it is created. It is sometimes developed by an external

entity, but with funding and specification from the agency. Because agencies can directly

control all aspects of GOTS products, these are generally preferred for government

purposes.

y ANOTS (NATO off-the-shelf or niche off-the-shelf, depending on the context) product isdeveloped by NC3A (for NATO Consultation, Command, and Control) to meet specific

requirements for NATO. In the more general context, niche off-the-shelf refers to vendor-

developed software that is for a specialized and narrow market segment, in comparison to

the broad market for COTS products.

This project aims to record and understand the life of a pebble on a river bed, as it is

picked up and moved from one part of a river to another.

The granular materials (sands and gravels) comprising the beds of rivers are typicallyin motion during periods of high river flow and stationary at other times.

A crucial aspect related to movement of these particles is the cause of the initial

motion which lifts them up in water. This process is often called entrainment'.

Particle entrainment is determined by many forces such as the velocity and turbulence

of the water flow. Each particle is subject to hydrodynamic forces such as lift and

drag, and the weight of the pebble is also a critical factor. To understand particle

entrainment processes we need to understand the stability and movement of individual

particles.

At present there is no device available which can measure the hydrodynamic forces

on a bed sediment particle when it is moving. The aim of the present work is to

develop a smart pebble which can record the hydrodynamic forces acting on itleading to its entrainment.

The smart pebble is a complete, battery powered unit equipped with two dual-axis

accelerometers and three angular rate sensors, a microcontroller, non-volatile external

memory and a user interface capable of communication with a PC. Inertial navigationsystem (INS) concepts are used as the basis of this work. An INS is a system which

can determine its exact location in three-dimensional space, relative to a knownstarting location.

Key focus areas/issues

Design considerations for the smart pebble include:

y Packaging, which determines the size and weight of the pebble?y Powering, to provide data logging for a sufficient time period with minimal energy

usage.

y Relative physical placement of the sensors to ensure the centre of gravity is at thecentre of the sphere.

y Signal conditioning systems.y Providing a bare minimum digital subsystem.y A compact and simple data communication interface.

Current major developments

A 40mm diameter smart pebble is designed, developed and successfully tested inside the

water flume.

Calibration is a critical process in inertial navigation system applications as it significantly

affects the final performance of the device. The smart pebble calibration process was done in

two independent steps

1. Individual sensor calibration (accelerometers and gyroscopes).2. Calibration of the whole smart pebble system.

The smart pebble has been tested using a shake table and in a flume to evaluate its final

performance. This picture shows the shake table setup.

The picture shows a comparison between the shake table and smart pebble output.

In the flume, motion of the smart particle performed by a Particle Image Velocimetry (PIV)camera is used as a reference measurement to compare the outputs of the smart pebble.

The following graphs show the comparison between acceleration obtained from PIV camera

and smart' pebble output.
