rther we can get ť by using eqn given below
σ = ( n*Qe2 *ť )/me ---------(1)
but ť obtained may not be accurate but we will get an idea of magnitude of ť . In a monovalent metal no of free e- /m3 is equals the no of atoms /m3 . From table we find that relaxation time T is of the order of 10-14 sec .Thus we can say that T is extremely small for monovalent metals.
from eqn. given below we can calculate mean free path λ-

λ = Vx * ťc ----------(2)


The relaxation time ť for metals refers to e- with Fermi velocity Vf .F..................[:=> Show Contents <=:]

reatment of soil surrounding ground rods is preferable and in some cases the only economically sound solution in obtaining low impedance of the ground system

The resistivity of affected soil layer and surface material used in the analysis of this paper is shown in Table I. When the influence of season factor is not considered, the soil is homogeneous, the resistivity of normal soil is 200m.This is called as the normal condition, the ground resistance, step voltage and touch voltage in the normal condition is used to measure the influence of the raining and freezing season.

INTRODUCTION
All modern hard disks are equipped with two
different heads “ one for writing and the other for reading. The principle of the writing
head is quite simple, i.e., generation of a magnetic field as electricity passes through the
head. The head focuses this magnetic field generated to the area on the disk surface
where the bit is to be written.
Conceptually the technique for read..................[:=> Show Contents <=:]

e of the major challenges currently faced by the technological world. It is a major issue in terms of storage capacity and in read-write speeds. But the technology to increase storage capacity has been somewhat solved out as new and advanced technologies are introduced to solve this problem. But the problem of read- write into these ultra high density storage disks at good speeds is a major problem. With the current technology which is available now, however large the storage capacity be, the amount of data which can be read or written into the disk has a limitation. This limit now a days is 1..................[:=> Show Contents <=:]

ures can be devised to protect against threats that pose the greatest risk. Second, we present countermeasures and discuss their effectiveness in protecting the crown jewels of an embedded system: boot code, operating system software and embedded hardware. A clear understanding of attacks and countermeasures enables a system architect to make rational investment decisions in designing a secure, embedded system.

Tamper-resistant storage techniques provide varying degrees of authenticity and integrity for data. This paper surveys five implemented tamper-resistant storage systems that use enc..................[:=> Show Contents <=:]
