Engineering and Construction Essays

We found that our laboratory sensors don’t have the ranges necessary to be implemented in a real-life traffic junction’s alarm system, as the operating ranges of our sensors generally didn’t lie within the values that should set a warning off. More heavy-duty equipment with greater ranges would be used in the traffic junction’s alarm system.

The Victoria university has the aim of building a facility that would facilitate student accommodation. The building is to be located at Ballarat Road and Tierman Street. The project is estimated to be accomplished in 10 months’ time. The building's structure should be such that it can accommodate 508 student beds in the 245 apartments.

Accurate estimation of productivity for the horizontal well can be difficult as compared to a vertical well estimation of productivity. However, the coupling of the fracture models and the horizontal models aids in coming up with a unified model for the deliverability of shale oil reservoirs, assuming the use of heavy oil that is non-Newtonian.

Although the use of V2G  and G2V has advantages, it also has some challenges that may impact negatively on its performance and use. Centralized control is currently in use in conventional grid management (Parsons, Hidrue, Kempton & Gardner, 2014). This, therefore, presents a major challenge in the management of distributed generation.

Fuel management in the hybrid car should be optimized to its maximum. This would provide greater mileage for the cars. The design should also consider employing hydrogen gas as it is a better component in providing fuel with water upon combustion but its use is limited by the lack of a safe and efficient system for storage.  

Industrial attachment can be understood as the work experience that is structured purposely within a working context, which requires the student to acquire and apply skills and knowledge relevant to their field of study. I had to therefore put into practice the skills that I had mostly theoretically learned in engineering. 

The design of the gear starts with determining the gear materials. Some of the desirable properties for effective gear materials encompass the endurance strength of the materials to prevent bending failure, the surface endurance strength that averts destructive pitting, low friction coefficient to avert scoring and minimal thermal distortion during heat treatment.

A transformer contains a wide events spectrum that includes design defects, maintenance errors, voltage surges, sabotage, lighting strikes, rapid unanticipated insulator deterioration, structural damage, and lightning strikes that can result in transformer explosion and fire or many other problems.

The team has been able to identify Ballarat West Employment Zone as their suitable site. This is in the light that Ballarat West Employment Zone (BWEZ) is considered the best investment project in the region. To ensure effective and intense research of the same, the team has dived duties and responsibilities amongst themselves.

This is the report for the author's work experience over the period from 1/12/2010 to 3/4/1011 at AAM Petrochemical Company, where located in an industrial city, Saudi Arabia. The author's position was as an operator at the Linear Low-density polyethylene plant (LLDPE). The plant consisted of a catalyst unit, reaction unit, and total pelletizing system (TPS).

The efficient management of facilities requires close and continuous interaction between both the facility managers and the security managers. Facility management involves the incorporation of the different activities within the built environment and the effective management of their effects on the people and the workplace in general.

A considerable number of multinational organizations are slowly coming to terms with the idea of globalization and thus the need to understand cross-cultural ethics. Most importantly, engineering fields such as civil, mechanical, electrical, chemical, and petroleum engineering fields have evolved to engage the use of a diversified workforce.

Engineering plays an integral part in ensuring the achievement of sustainability goals. Besides, engineering activities, designs, and recommendations are the major factors contributing to the deteriorating environmental condition. With poor living conditions, the safety and health of the public are at risk.

The elements may have an influence on one another either in a direct manner or an indirect manner as each seeks the maintenance of the system's activities with the intention of realizing a given objective. For instance, all the systems have with them both input and output mechanisms despite them operating in ever-changing environments. That said, the instance of the capability may mean the capacity, quality, or ability to realize a given operational effect.

Drawings help determine possible fault points. General arrangement drawings are one such document. From the drawings of the arrangement, the surface nature, joints, weight bearers, and force balances can be determined easily, rotators and possible places of stress concentration can be easily located and analyzed. Electrical drawings are the other important drawings in fault diagnosis.

The organization has its headquarters located in Geneva, Switzerland. The group was created by members from both developed and developing countries where most of its members are the developing countries. The group started with different aims, creating fair and transparent trade around the world. It is also working towards settling disputes that arise in trading activities among the countries.

Hydraulic elevators are often supported by a piston at the bottom. The piston pushes the elevator up from one floor to the other. Hydraulic elevators travel at a speed of two hundred feet per minute. There are two types of hydraulic elevators. The first type is holed hydraulic elevators which have a sheave extending below the elevator pit.

Aggregates used on highway surface pavement are subjected to impact and abrasion due to traffic movement. Thus, the road aggregate has to be tough to resist disintegration due to impact and abrasion. Both abrasion and impact of the pavement aggregates were determined in this experiment. The two tests have given us the values used to determine the properties of the aggregate pavement.

Engineers are expected to work towards ensuring accidents in industries are eliminated through discharging their job obligation while considering safety issues. The work of engineers is crucial and it has a major role in making sure that their operations prevent the occurrence of accidents.

A Computer Numerical Control (CNC) is one in which the functions and motions of a machine tool are controlled as a result of a prepared program containing coded alphanumeric data. 3 axis CNC mill is rapid prototyping technology for cutting materials that are often quite forgiving such as rigid foam or insulation.

Lathe machine is designed specifically for sanding, cutting, turning, and grooving materials with relative hardness. They are applied in a wide range of uses due to their inherent versatility and have the ability to machine a number of materials. The machine eliminates or gets rid of materials from a rotating workpiece.

The above comparison and contrast between concrete and steel show that both materials are essential and commonly used in the construction industry. Both have considerable benefits based on their physical characteristics and other external factors. Concrete seems to outweigh steel, and it is, therefore, a better option.

The methods that have been chosen for this project is the penetrant method and the ultrasonic tests. The penetrant method has been selected because it has the ability to show surface defects like the cracks effectively. It is also relatively cheaper and easy to use. The penetrant method works as discussed above.

The background illustrates the mechanical fault committed in the manufacture of the Pinto car model, its consequences to the car users, and the appropriate mechanical solution. Consequently, the mechanical faults are examined as the flaws, which were realized in the location of the gas tank In addition.

Robert Moses is the planner behind the highway and most of the other American cities' modernization. Moses assured that most of the road is straight as it stretches through the borough and most of the curves that can be identified. The road passed through residential areas, which was a precedence to the demolishment of the buildings.

The stream evaporates under reduced pressure, producing strong local cooling, as well as a high concentration of halon in the immediate vicinity of the fire. In this mode, extinguishment is achieved by cooling and oxygen deprivation at the core of the fire, as well as radical quenching over a larger area.

From the entire mentioned incident we are able to conclude that the fire outbreak may have been caused by the defective electrical appliances and fitting within the hall, Furthermore, the public reported that member within the congregation had been burnt during the occasion by a heater, and the personality was not identified within the given time. 

From the calculations, it can be concluded that the earth dam is well designed in terms of stability with the downstream slope being slightly more stable than the upstream. The F.S. in both cases is higher than the recommended values and this makes it possible to use change soil parameters without the slopes reaching the unstable zone.

A concrete frame is a beam frame system and is very economical in the building. It does not require finishing, painting, or fire protection. It forms suitable structures for warehousing, community halls, and sports halls. The frame consists of reinforced concrete fixed to the columns. Reinforced concrete frames have a thermal expansion.

A fire action is mandatory to be included in all buildings where there is a concern for fire safety. During fire incidence, it is important to ensure that there is enough fire marshals, security team, and building staff this being very important in ensuring that nobody moves back to the building unless permitted. 

From able 2 results, it is clear that drivers can negotiate corners which are less sharp at higher speed with no danger of the car slipping but when the corner is sharp the safe speed of negotiating corners is lowered. At 500m radius corners, the F1 car is capable of moving at as much speed as that on a straight racecourse.

The risk of fire in buildings is common due to the nature of activities and the electrical installations in the building. Fire in a building can be caused by several factors and it may lead to the total destruction o property and loss of life. The building design has to consider the concepts of fire safety in accordance with the codes. 

Thick aerofoils are likely to give the desired lift at a low aircraft speed but this would be accompanied by creating drag that is unreasonably high. For one to attain the required lift at a smaller angle of attack the aircraft need to move at a higher speed. The effect of changing the angle of attack is clearly visualized by using the XFLR5 software

Essentially, studying forces that act on a moving body helps one to develop the aerodynamics of the cars that are designed for racing. Therefore, this analysis gives one ideal case that is used to improve the development of the racing F 1 cars. Changing the speed of the car at a given curve with a given radius affects the centripetal force.

The system makes use of varied methods that expose a building and allow the viewing of certain parts of the building from different points on the boundary and to ensure visible effective ‘unprotected areas’ are easily calculated. Thus, if an area from the boundary is unprotected then the smaller its effective or notational area is. 

The process involves creating a mold, melting the steel, pouring the molten steel, cooling, removing the parts from the mold, welding, and machining.  The processes are simple but require a lot of expertise. The total cost of manufacturing a single unit is $ 110. It can be sold at a price of S 130 in order to obtain profitability. 

The results confirmed that airfoils can only have a significant effect when dealing with high speed. This is clearly seen in the case when a small radius is being used putting the maximum speed below. In this case, it was found that the maximum speed for the case of excluding airfoils and that of including airfoils were almost equal.

Fire is one of the most dangerous hazards that is known to take many lives if not anticipated and prevention is difficult. However, an elaborate risk of fire occurrence basement within a premise is important in determining the possible risk of a fire occurring as well as putting appropriate fire prevention measures.

It seems like more information needs to be provided about electric cars. Most of the respondents do not have knowledge about them and they need to understand their work, what will be required of them and the various changes they will be anticipating to have. The respondents would wish to have the information from television Ads and Live Demos.

Comparing the output voltages at no load and during load, for instance at a constant speed of 1600 rpm, it was deduced that on load, the output voltage was slightly higher by a margin of 0.5V. Since DC power is a product of voltage and current, it was evident that on load there is a better input to output power conversion ratio.

The very crucial principle for the strong design of a given structure. It is the resultant turning moment that acts on a beam as a result of all the forces that act on one side of a particular point. The moment is basically the principle of the construction lever. The moment can be considered as a combination of distance and force.

Resistors act as voltage droppers or voltage dividers in a circuit. Electrical resistance is the resistance of the flow of electrical current. To overcome this resistance, there is voltage consumption across the resistor\, and this leads to a voltage drop. Since the resistor causes the electrical resistance then it is a voltage dropper.

Contractors have therefore been waiting for redemption to this problem. BIM has therefore come in handy to solve this age-old problem of rework and redoing of work, it has greatly reduced rework therefore 90% favored BIM, 80% believed in quality improvement while 90% believed that BIM simplified their work in a great way.

The aggregate of exercises is done to counsel an expert's proposal on how best to move toward the buildup and Lead. At our level, the mats will be kept up, and the garments, too. This is to diminish track-in buildup and Lead. Incase, the repeat of vacuuming garments and tangles is what will change from once every fortnight to once-reliable.

Highway construction industries are one of the categories of industries that make up the entire group of construction industries. Construction industries are the largest operating industries globally. The construction industries are the largest industry in terms of employment and contribution to the gross domestic product of the nation.

The need to manage waste from electrical and electronic equipment, packaging and packaging wastes, and to control the production of pollutants such as greenhouse gases, all require the adoption of a holistic approach in designing a wide range of products and systems, and mechatronics concepts will be more needed than any other engineering concepts.

CO2 emissions for the injection and recycling of the gas during the EOR operation can be estimated by adopting an emission factor. The value of 0.048 tonnes of CO2 per incremental barrel of oil produced is derived from literature [6] to account for fugitive emissions, flaring, and auxiliary processes.

Key ideas adopted from the project include consideration of the competencies developed through volunteering, the impact of this competency development in business, and individual behavioural changes such as increased self-confidence, motivation, and pride in the company (Corporate Citizenship, 2010, p.9).

Analysis of studies conducted about seismic activities in the United Arab Emirates suggests that UAE is classified as Zone 0 with generally no sprinkler system protection required. However, being historically untouched by strong seismic activity and scientifically classified as hazard-free is not a guarantee that there will be no such incident in the future.

Naturally, ammonium nitrate is an explosive compound. To set off an explosion involving ammonium energy only activation energy is needed, this may be a flame or a spark.  Once ignited, the ammonium in the nitrate becomes the fuel while the nitrate becomes the nitrate. These chemical properties of ammonium nitrate make bombs containing it very lethal.
