Engineering and Construction Essays

Generally, in the product lifecycle management process, CAD is the major geometry authoring tool. It is composed of software and hardware of special purpose. The latest software packages have 2D, which is about drafting systems, and 3D, which is about solid design modelers and parametric surfaces (Groover & Zimmers, 1983).

The generic type of Software is produced for commercial purposes and is able to perform several tasks in one package. It is important that you put into place certain considerations when choosing any Software, like Computer Aided Drawing Software. One should consider whether the software will perform everything it is needed to.  

Almost 98% of all machines are currently designed using Solid modeling tools. SM normally allows designers to make larger changes with little changes. It involves computer-aided designs which can be defined as one of the computer-aided programs used in creating two or three dimensions graphical representations of the physical object.

3D and 2D software are some of the programs used in Computer-Aided Designs. On the other hand, Finite Element Analysis is the use of a computer model of either design or material that is stressed as well as analyzed for accurate results. 3D software is software that produces computer-generated imagery-CGI by using 3D modeling.

The author of the paper will begin with the statement that the underside of a smoky layer 10m x 8m is radiating like a flat, isotropic plate at 475°C to the floor of a compartment 1.20m below. The mean emissivity is 0.35 and the floor is homogenous/flat plate at 48°C.  What is the rate of heat transfer from the smoke to the floor?

3 CAD software are applications used by engineers and scientists to create wireframe drawings of objects, which they can rotate to view from multiple angles; users can also overlay materials on wireframes. 3 CAD is used because it is a quick, easy and precise way of making designs of buildings without having to build sculptures.

The local frequency receiver is made to track the signal frequency while it is operating due to the ability to have the image and the desired frequency appears together with the mixed local frequency. From the example given of the broadcaster operating at 465kHz within 550-1600kHz, then the local oscillator has to be tuned at 465+550 kHz=1015 kHz.

The main three different types of extinguishers contain water, powder, and carbon dioxide. The respective extinguishing method is only used where they starve and smother fire ultimately killing it. In other classes of fires, water can assist in the spread and growth of the fire. Water extinguishers are used in fighting class A fires.

The venture meter is calibrated, with its coefficient being determined, and the overall loss of mechanical energy across the venture is investigated. The venture meter is located on a hydraulic bench and the system is represented schematically. When water is pumped from the reservoir serving as the holding tank it passes into the weigh tank.

If safety measures are not taken into account in the residential buildings then in case of any disaster, there will be lives lost. Examples of residential buildings include single-family houses, multi-family houses, duplexes, townhouses, condominiums as well as hostels. These residential houses use different types of materials that include steel, concrete, wood as well as aluminum, and plastic.

The natural ventilation in a compartment is governed by the size of the fire, its position within the enclosure, and the shape of the compartment (Ingason & Lönnermark, 2014). Fires that are influenced by ventilation are those whose rate of energy released is limited by the availability of oxygen in the compartment.

The firebox’s roof floor and walls are made out of 0.025 m thick ‘Monolux 500’ lining with one wall constructed from fire-resistant glass. An adjustable door opening, 225mm high and opens between 0 and 0.15m wide. The fuel rests on an axle at the bottom of the floor with a balance to measure the fuel’s weight. (B.J.McCaffrey, 1981) 

Combustion is the process in which oxygen combines with other compounds to result in water and carbon dioxide. This process may occur in two forms either complete combustion or incomplete combustion. Complete combustion is the process by which elements in fuels react in the presence of plenty or excess amounts of oxygen to produce carbon dioxide and water.

While this experiment allows the development of compartment fires understanding, it aims at assessing the development from the ignition stage through to the decay stage. This understanding shall be brought forth by setting up experiments to observe the effects of controlling fuel and limiting ventilation in two separate instances.

The building can be described as circular with a porch-like structure entailing columns located under a pediment. It also has a characteristic porch that is linked to the rotunda via a rectangular vestibule which is under a coffered dome with a central opening. Any building stability will be determined by the foundation laid for construction.

Material strength can be established through the failure theory which is used to study the structural design to determine the safety of equipment before production. Once a material cracks or forms a flaw there is a tendency for it to fail at a stress that is lower than the threshold material strength.

The apartment block contains a ground floor and four (4) upper floors, with three self-contained flat units on each floor, totaling 15 flat units across the building. Each of the flats on the upper floors can be accessed indirectly off a single stairway and a single lift servicing a common corridor.

Construction methods accompanied with materials to be used must be selected considering the design specification, legal requirements, time constraints, amount of money set aside for the project, the effect of the building method on the environment as well as the intended use of the structure to be constructed.

Construction Materials and MethodsIt are very difficult to source green materials that can adequately make the building meet the BREEAM ‘excellent rating’. In addition, green materials may negatively impact the program of EIC building construction because materials will require long lead-in times. The materials will also lead to increased costs.

It is essential to state that an excellent BREEAM rating is important for proper environmental assessment as well as the delivery of environmental sustainability. Further, this technique is expected to act as a measurement in relation to the environmental performance of other buildings around the institution.

BREEAM utilizes an express weighting framework got from a blend of accord-based weightings and positioning by a board of specialists (Azano, 2003). The yields from this activity are then used to decide the relative estimation of the ecological segments utilized as a part of BREEAM and their commitment to the general BREEAM score (Barney, 199).  

A minor injury to the ACL can lead to knee complications during physical activities. That is; knee injuries are very common, mainly ACLs caused on the sports field mainly. The ligament replacement is conducted where during the surgery the knee joint is replaced with a synthetic medical joint identified as Prosthesis (NLM, 2016).

It is well known that not every kernel of corn pops. During the preparation of popcorn, some un-popped corn remains at the bottom of the baking bag and as a result of this, the quality of the popcorn reduces. Because of this, a number of questions remain ringing in the minds of many people in relation to the causes of unpopped corn.

As a result of the fire outbreak witnessed at Mayson Machining Ltd, conducting an investigation into the cause of the accidental fire was imperative. In Ontario, Canada, the Fire Marshall is responsible for conducting investigations into the factors that led to the disaster that resulted in losses worth $1.8 million (CBC NEWS, 2014)

The RRFSO 2015 For fire strategy is required that submarine vessels should be designed in a manner that ensures the smoke does not spread across the vessel and fire smoke and heat are detected as soon as possible. There are a number of fire strategy measures that are undertaken to protect submarine vessels from destruction and loss of life.

The ignitability and combustibility reduction of wood products is based on physical means with effects on different stages of burning and ignition. The examples are as follows: when heat is induced, it changes the internal structure of the wood at the molecular level; the chemical and physical processes of compounds that result from these changes

Please list the Navier-Stokes equations together with the equations of energy conservation (not just the names but also the mathematical expressions). Explain the physical meanings of each term in the momentum conservation equations.

Turbulent models are vital in calculating the mean of glow directly without following the normal procedure of first considering the flow field that has full-time-dependent properties. It is important to note that a turbulent flow in any given fluid has many varied features on length scales that differ but ultimately interact. These turbulent models help in predicting the turbulence effects in a fluid flow (Arya, 1990).

Recycled water may come from different sources that may be including effluent, stormwater, and also seawater. Effluent may be recycled from either a wastewater treatment plant or a sewage plant. The water quality of such water mainly depends on the purpose for which the water is supposed to fulfill.

It is also important to maintain boundary and surface conditions in all parts of the building to facilitate the evacuation of tenants through the central staircases. The owner is advised to install mechanical smoke shafts at extreme end of the corridor and staircases of the building. However, occupants should be made aware of safe evacuation when a fire occurs.

The extended corridor should be provided with additional fire protection to maintain its integrity. Design changes to the plan should also be considered to help safeguard the safety of the occupants. An alternative escape route should be designed so that the occupants have another means of escape should one of them be compromised by the fire.

BAT involves the application of the most effective method of disposing of waste. Oil refinery processes tend to generate many oil wastes. The company has to devise proper techniques for of disposing of the generated wastes to prevent the generation of hazardous gases during decomposition or exposure to harsh environmental conditions.

Operation Vanguard is the system developed. Its idea is to evaluate the likely sequence of events to predict future terrorist attacks. This is through the system of system engineering technology. A cipher is spurious of the maxims of rules in front of it. A encipher is a call or heaping up of substitute installations pile draw up to supply profits battle-cry attainable by the trappings desolate.

Buildings have the ability to present potential risks both during the contraction process and in their operations. A lot of responsibility is placed upon the shoulders of those responsible for designing, commissioning, constructing, and the operations in the buildings to ensure the health and safety of the users and contraction workers. 

@2016AbstractThis report details the design of a fire protection system for a residential building with the dimensions of twenty five meters high with a single staircase. The report entails the procedure of selection of the most suitable fire

Modeling of turbulence flows is necessary because most of the flows encountered in engineering applications are turbulent in nature and predicting these flows is very challenging since there are no analytical solutions for the non-linear fluid flow equations. Capturing all the fluctuations or every single vortex in fluid flow may be impractical for turbulent flows.

Engineers and international firms can benefit from a clear understanding of the correlation between an engineer’s values and the corporate culture. In this regard, corporate culture refers to the values of corporate managers as well as their subordinates. There is a strong corporate culture when the values of employees are in agreement with those of the organization.

Drive, spindle, motors, and CNC controls, among others; all are machines manufactured by Okuma. The company has reliable and innovative technology for CNC machining coupled with comprehensive, localized service protection, which allows users to run the machine confidently and continuously to maximize profits. 

The paper explores the implementation of adaptive feedback cancellers for hearing aids. The adaptive filter in adaptive feedback cancellation is employed for modeling the acoustic feedback pathway amid the loudspeaker of the hearing device and the microphone. Adaptive filters are a significant parameter as they provide an exchange between fast conjunction and low, stable state misalignment. 

Silica aerogels synthesis can be grouped into three general steps: The first step is the preparation of gel, whereby the silica gel is acquired through sol-gel process. According to Dorcheh and Abbasi (2008, p.11), the preparation of sol happens through a silica source solution as well as by adding a catalyst, resulting in gelation.

The system detects and controls residential fires and therefore provides protection against the loss of life, injury, and damage to property. If the system is installed as designed in accordance with the residential standards, it is expected to prevent the fire from reaching flashover, thus improves the opportunity of the occupants to escape (Li & Baker, 2012).

Thomas and Heselden (1972) offer a more detailed review of theories regarding wood crib files, flashovers, and pool fires in compartments. It is the conclusion of this dissertation that there is an apparent correlation between total heat released and the amount of oxygen consumed during the combustion process of compartment fires.

The principal point of this examination is to investigate the relationship in the middle of hardenability and organization of various sheets of steel. The prerequisites gear for this examination incorporates a warmth treatment heater, extinguishing installation with a water stream, Rockwell C hardness analyzer, and hardware as required.

A definition of the potential causes and effects of the failures were determined and priority risk numbers were assigned thereof. Possible mitigation measures for failure modes that had high-risk priority numbers were proposed and a recommendation on ways of improving the efficiency of the exhaust system are also dealt with.  

The thought behind an incorporated chip is that a few sorts of parts are coordinated into a solitary bit of silicon (a solitary CPU, for example, one or more execution centers, number juggling rationale unit (ALU) or 'gliding point' processor, registers, direction memory, store memory, and the info/yield controller.

The team ought to have understood the risks involved in the construction. The gravity deemed a project threat that rendered concrete pumping almost unattainable. The high temperatures resulted in reduced work hours and also reduced the times when certain materials such as concrete could be applied. These were some of the unavoidable risks.

It is currently in its fifth edition which is commonly referred to as PRINCE2 2009. In fact, the PRINCE methodology was originally established in the 1980s for managing IT projects. The methodology was reviewed and updated in the year 1996 by project management specialists to make it more widely applicable to different industries. 

Prince2 steers project managers through all fundamentals for administering a successful project. It provides a methodology for delivering efficiencies, and increased agility while at the same time reducing costs plus many more compelling organizational reasons to select it as the controlling solution in project management.
