One of the most common and difficult problems to solve in industrial power systems is the location and elimination of ground fault. Ground faults that occur in ungrounded and high resistance grounded systems do not draw enough current to trigger circuit breaker or fuse operation, making them difficult to localize.

Techniques currently used to track down faults are time consuming and cumbersome. A new approach developed for ground fault localization on ungrounded and high resistance grounded low voltage systems is described. The system consi ....etc

hello
i intend to make a capacitance and resistance measuring device using 8085.using 8085 is a compulsion as it is a part of my academic project.
so how do i calculate the exponential function in 8085 to calculate the value of capacitor?
also, how to measure resistance using 8085 itself?

regards

SKID RESISTANCE ON PAVEMENTS


INTRODUCTION
Road engineers & users are concerned with the safe passage of vehicles that operate over them.
Safety on road is assessed by its skid resistance.
Slippery pavements are known to be the cause of many road accidents and fatalities.
Skid resistance involves the complex interaction of pavement , vehicle and environment factors.


SKID RESISTANCE
Skidding is the jerking of the wheels of the vehicles when it locked due to the sudden breaking , if the frictional ....etc

H-L Lin1, T Chou2, and C-P Chou2
Department of Vehicle Engineering, Army Academy R.O.C
Abstract:
Many parameters affect the quality of the resistance spot welding (RSW) process. It is not easy to obtain optimal parameters of the RSW process in the automobile industry. Conventionally, the Taguchi method has been widely used in engineering; however, with this method the desired results can only be obtained with the use of very discrete control factors, thus leading to uncertainty about the real optimum. In the process ....etc

To secure digital assets, a tasteful integration of a variety of technologies and processes is necessary. Tamper-resistance is being increasingly used as an important piece of a more comprehensive security system. It provides an effective barrier to entry and protects digital assets in the embedded systems from most people and most attacks. Embedded systems pose unique security challenges because they are largely used in relationships where one party wants to put a secure, embedded device, in the hands of another, with the assurance that the se ....etc

EXTRAORDINARY MAGNETO RESISTANCE

Data handling is one 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, t ....etc

1 Aim of experiment
We are going to determine the value of an unknown resistance using a meterbridge
and then make furthur accurate measurements using Carey Foster
bridge to take into account the specific resistivity () of the bridge wire.
Finally measuring the radius and length of the unknown resistance we can
determine the specific resistivity of the material given.
2 Apparatus required
a)An unknown resistance
b)A known resistance(variable)
c)A galvanometer
d)A very high resistance of the order of 15000
to protect ....etc
