Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

1.0 The Structure of Materials and Periodic Table of the
Elements
1.1 The Structure Of Materials
1. Crystal structures or crystals :
Atomic arrangements which have a repetitive pattern in all the three
dimensions of space.
2. Molecules :
Two or more atoms combined chemically.
3. Microstructure :
The appearance of the structure of a material under a microscope
and consists of phase structure and grain structure.
4. All solid materials consist of a large number of particles called
molecules that are bonded together to form a bulk material.
Each molecule is further composed of tiny particles called atoms.
Individual properties of atoms and their arrangement in the
molecule determine the properties of the materials.
1.1.1 Atoms
Atom is the basic unit of an element formed for all materials weither
for solid, gas or liquid.
An atom consists of the nucleus and the electrons.
Atom Charge
Proton Positive
Neutron Neutral
Electron Positive
The valence electrons are the outer electrons and are least firmly
bound to the atomic nucleus and revolve in the outer orbits
Fig 1 : The position of electron, nucleus and orbit in an atom
1.1.2 Elements (unsur)
Elements is a combination of two or more same atoms bonding
together.
Elements are pure substances.
Example: Oxygen (O), hydrogen (H), aurum (Au), Carbon (C),
Helium (H)

2. 1.2 Atomic Numbers, Atomic Masses and Atomic Orbits
1. Atomic Numbers
Neutral atom = numbers of proton = numbers of electron
2. Atomic Masses and Atomic Weight
Atomic Weight = Atomic masses of an element
Atomic masses of Hydrogen
Atomic Masses = atomic numbers
= number of proton + number of neutron
3. Atomic Orbits
Using the 2n2 formula to state the total of atoms in every orbit,
where n is total of orbit
1st orbit, n = 1
Total of atom = 2 (1)2 = 2
2nd orbit, n = 2
Total of atom = 2 (2)2 = 8
1.3 Periodic Table of the Elements
1. It is a chart of list of elements which all the elements with same
chemical properties in one line as one group.
2. The horizontal rows of elements on the periodic table called periods.
The vertical columns called groups or families.
3. Characteristics :
i. 18 lines of boxes in vertical, 7 lines of boxes in horizontal
ii. 8 groups start with group I until VIII
iii. arrange by atomic number start with Hydrogen
iv. elements in same line horizontally has same total of orbits
v. chemical properties of an atom depend on total of valency atom
vi. when electron are followed from group I to group III, metal
properties of an element become lessen but total of electron will
increase and become the non-metal properties
vii. elements in group I has 1 electron in outer orbit, elements in group
II has 2 electron in outer orbit
viii. each period has same total of orbits
4. Usages :
i. to classified certain elements easier
ii. as a revision where elements reactive properties can be known (way

4. 1.5 Types of Bonding
1.5.1 Covalent Bonding
Occurs when two atoms (same elements) have a tendency to accept
electrons which are satisfied for both by sharing the electron valency.
1.5.2 Metallic Bonding
Occurs when two metal atoms have a tendency to give up their
electrons and shared with all atoms close to them and formed of an
electron cloud that spreads throughout the solid metal.
1.5.3 Ionic / Electrovalence Bonding
Exists between two unlike atoms that had a strong tendency to give
up electrons (a metal), close to an atom that has a strong tendency to
accept electrons (a nonmetal) and allows a transfer of one or more
electrons depending on the valence of the atoms

5. 1.6 The Stages Of Grain Structures Formation
1. Solidification process occurs along with the grain formation.
2. Nucleus tips freely find their own way to much colder place.
3. Causing the nucleus to grow and expanding.
4. The expand will form the secondary dendrite arm with 90 to each
other.
5. This will continue until a structure called dendrite structure existed.
1.7 The Differences Between Base Metal and Alloy
1. Base metal
metal has same elements, extreme properties and cannot fulfill the
need for engineering work.
its characteristics :
(i) malleable – can be shape to many form
(ii) ductile – can be form to fine wire
2. Alloy
a metal alloy is a combination of two or more metals or a metal
and a non-metals.
1.8 Types Of Solid Solutions
Disordered Solid Solution
Solute and solvent atoms are randomly distributed on lattice sites
Ordered Solid Solution
The atoms (solute and solvent) take up preferred positions and the
solution becomes ordered
Interstitial Solid Solution
Atoms of small atomic radius fit into the empty spaces or interstices
of the lattice structure of the solvent atoms
