Requirement engineering

The role of requirement engineering phase in the development of software product servers as a strong base for the successful completion. There have been numerous models presented so far, in this phase, to improve the mistakes that are supposed to be the part of requirement engineering process. It is also to make the further development … Read more

Frost damage

Water can be found in concrete as product of the hydration during the mixing or as a result of filtration induced by cracking and structural joints. When this water freezes, it creates pressure in the pore network of the concrete and generate tensile stresses that produce more cracking, surface scaling and possible loss of the … Read more

Construction costs

Building Design and Construction is the process of creating a plan and adding structure to real property or construction of buildings. In the modern industrialized world, construction usually involves the translation of designs in to reality. A formal design team may be assembled to plan the physical proceedings with the other parts. The design usually … Read more

Helicopters

Helicopters are extremely useful pieces of flying equipment, with the ability to both take off and land vertically. This along with being able to hover in a given place and fly in any direction, including backwards and to either side, means that they have a huge amount of uses worldwide and in many different environments, … Read more

Lean manufacturing for Indian automotive companies

Our initial results showed positive response from a majority of companies that we surveyed. However, a subsequent follow-up study of the inner working of these companies presented different scenarios and therefore helped us to understand the real problems facing these companies. Our in-depth research shows that among Indian automotive companies, there has been a remarkable … Read more

Harmonic currents and their effect on distribution transformers

Literature review Introduction This project examines harmonic currents and their effect on distribution transformers. Details of transformer losses associated with harmonic currents will be discussed. Data from a residential distribution transformer will be used to illustrate the amount of harmonic current present. Harmonic currents have existed in electrical power systems for many years, but have … Read more

Power quality problems

1.1 INTRODUCTION Source current distortion has become a major power quality problem in industries and utility power system because of higher usage of nonlinear loads in the system. Voltage harmonics in power distribution systems arise due to current harmonics produced by the nonlinear loads. The non-sinusoidal currents through electrical systems and the distribution-transmission lines, additional … Read more

Cement and concrete

Water, unsurprisingly, is the number one most consumed substance in the world. Concrete, surprisingly, is the second most consumed substance in the world. Concrete is created by mixing cement, water and aggregate. Cement is the vital binding component in the concrete production process. This combination is the most abundantly manufactured material in the world and … Read more

Resistance welding

Resistance welding is a method to join two metals that involves the application of force or pressure as well as electricity at a spot where the two metals touch. It is also known as resistance spot welding or resistance seam welding. The electricity creates resistance heat at the point where the two metals touch, creating … Read more
