Types And Uses Of Coupling Devices Engineering Essay

Types And Uses Of Coupling Devices Engineering Essay A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power.In machinery, a device for providing a connection, readily broken and restored, between two adjacent rotating shafts.A coupling may provide either a rigid or a flexible connection; the flexibility may permit misalignment of the connected shafts or provide a torsionally flexible (yielding) connection, mitigating effects of shock Couplings do not normally allow disconnection of shafts during operation, though there do exist torque limiting couplings which can slip or disconnect when some torque limit is exceeded. A common type of rigid coupling consists of two mating radial flanges (disks) that are attached by key-driven hubs to the ends of the shafts and bolted together through the flanges. Alignment of the shafts is usually achieved by means of a short cylindrical projection (rabbet joint) on the face of one flange that fits snugly into a circular recess on the face of the other flange. The chain coupling consists of two hardened-steel sprockets, one on each shaft, with a nylon or metal roller chain wrapped around the closely aligned sprockets and connected at the ends. Clearances between the sprocket teeth and the chain allow for a small amount of shaft misalignment. For connecting shafts whose axes intersect but are inclined to one another at a larger angle than a flexible coupling can accommodate, universal joints are used. The most common of these is the Hooke, or Cardan, joint, which consists of two yokes attached to the shaft ends and a cross-shaped connecting member. Uses Shaft couplings are used in machinery for several purposes, the most common of which are the following. To provide for the connection of shafts of units that are manufactured separatelty such as a motor and generator and to provide for disconnection for repairs or alternations. To provide for misalignment of the shafts or to introduce mechanical flexibility. To reduce the transmission of shock loads from one shaft to another. To introduce protection against overloads. To alter the vibration characteristics of rotating units. Types of shaft couplings Drive couplings A coupling is used to connect two in-line shafts to allow one shaft (driver) to drive the second shaft(driven) at the same speed. A coupling can be rigid or, more normally, it can be flexible allowing relative radial, axial or angular movement of the two shafts. Unlike the clutch the coupling transmission is not designed to engage-disengage as a normal operation Coupling Type Coupling type Description Rigid Flange locked onto each shaft. One flange with recess and the other with matching spigot. Flanges bolted together to form rigid coupling with no tolerance for relative radial, angular or axial movement of the shafts. Muff Coupling Long cylindrical coupling bored and keyed to fit over both shafts. Split axially and clamped over both shafts with recessed bolts. Rigid coupling for transmitting high torques at high speeds Beam Coupling Single piece cylindrical coupling with a hole bored through its entire length. Each end bored to suite the relevant shaft. The helical slot is machined in the coupling in the central region. The reduces the coupling stiffness. The coupling is positive with some flexibility. Pin As rigid coupling but with no recess and spigot and the Bolts replaced by pins with rubber bushes. Design allows certain flexibility. Flexible Rubber disc As rigid coupling except that a thick rubber disc bonded between steel plates is located between the flanges. The plates are bolted to the adjacent coupling flanges. Spider Both half of the couplings have three shaped lugs . When the coupling halves are fitted together the lugs on one half fit inside the spaces between the lugs on the other side. A Rubber insert with six legs fits within the spaces between the lugs. The drive is by the lugs transmitting the torque through the rubber spider spacer This coupling is only used for low power drives. Bibby Coupling The outer flanges of the two half couplings are serrated. A spring fits into the serrations connecting the two halves. Chain Coupling Flanges replaced a sprocket on each shaft. The coupling is by a duplex chain wrapped over both adjacent cnoupling. Gear Coupling Both coupling halves have a raised rim machined as an external gear. The sleeve which couples the two shafts comprises two halves bolted together, each half having a machine internal gear. This coupling requires lubrication. The coupling is capable of high speeds and high power capacity. Metastream Coupling Coupling halves connected via stainless steel diaphragms. High speed high torque capability with good dynamic balance. Single coupling will accommodate angular and radial misalignment and fitted in pairs also allows lateral misalignment. Fluid Coupling Based on both coupling halves having vanes within a housing containing viscous fluid. The rotation is transmitted from one side to the other via the viscous fluid. the coupling provides a soft start. Universal Coupling Coupling which allows large angle between drive halves(20-30o). Generally based on a yoke mounted on each shaft . Between to yokes is mounted a trunnion cross. Needle bearings are used at the bearing points between the cross and the yokes. These type or units are used in pairs on carden shafts. Uses widely on rear wheel drive vehicle propshafts Universal Coupling- Uni-Joint Simplest type of coupling which allows large angle between drive halves. Each side of coupling includes protruding pins. The halves of the coupling are fastened in a pivotting assembly. At all angles up to about 40othe pins interlock with each other and rotation on one half forces the other half to rotate. Low power use only . Not smooth. Not reliable. Really only suitable for remote manual operations. Rigid coupling Rigid couplings are used when precise shaft alignment is required; shaft misalignment will affect the couplings performance as well as its life. Examples: Sleeve or muff coupling Clamp or split-muff or compression coupling Flange coupling Flexible coupling Flexible couplings are designed to transmit torque while permitting some radial and axial and angular misalignment. Flexible couplings can accommodate angular misalignment up to a few degrees and some parallel misalignment. Examples: Bushed pin type coupling Universal coupling Oldham coupling Bellows coupling à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬ low backlash. Spider or jaw coupling à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬ elastomeric inserts for flexibility, vibration reduction. Thompson coupling Resilient coupling Disc coupling Some applications like printing machines, roll forming machines, laminating machines, corrugated paper machines and paper making machines require an extreme and variable parallel offset. For these machines the coupling Schmidt-Kupplung is a solution. Torque limiting coupling Torque limiting couplings, or torque limiters, protect systems against overtorque conditions. Requirements of good shaft alignment / good coupling setup it should be easy to connect or disconnect the coupling. it should transmit the full power from one shaft to other without losses. it does allow some misalignment between the two adjacent shaft roation axis. it is the goal to minimise the remaining misalignment in running operation to maximise power transmission and to maximise machine runtime (coupling and bearing and sealings lifetime). it should have no projecting parts. it is recommended to use manufacturers alignment target values to set up the machine train to a defined non-zero alignment, due to the fact that later when the machine is at operation temperature the alignment condition is perfect Tools to measure shaft axis alignment condition it is possible to measure the alignment with dial gages or feeler gages using various mechanical setups. it is recommended to take care of bracket sag, parallaxe error while reading the values. it is very convenient to use laser shaft alignment technique to perform the alignment task within highest accuracy. it is required to align the machine better, the laser shaft alignment tool can help to show the required moves at the feet positions. Coupling maintenance and failure Coupling maintenance is generally a simple matter, requiring a regularly scheduled inspection of each coupling. It consists of: Performing visual inspections, checking for signs of wear or fatigue, and cleaning couplings regularly. Checking and changing lubricant regularly if the coupling is lubricated. This maintenance is required annually for most couplings and more frequently for couplings in adverse environments or in demanding operating conditions. Documenting the maintenance performed on each coupling, along with the date. Even with proper maintenance, however, couplings can fail. Underlying reasons for failure, other than maintenance, include: Improper installation Poor coupling selection Operation beyond design capabilities. The only way to improve coupling life is to understand what caused the failure and to correct it prior to installing a new coupling. Some external signs that indicate potential coupling failure include: Abnormal noise, such as screeching, squealing or chattering Excessive vibration or wobble Failed seals indicated by lubricant leakage or contamination. Checking the coupling balance Couplings are normally balanced at the factory prior to being shipped, but they occasionally go out of balance in operation. Balancing can be difficult and expensive, and is normally done only when operating tolerances are such that the effort and the expense are justified. The amount of coupling unbalance that can be tolerated by any system is dictated by the characteristics of the specific connected machines and can be determined by detailed analysis or experience.

Fall of Rome DBQ Essay - 815 Words

The Fall of Rome The great Roman Empire expanded across all of Europe and into the Middle East. Its military was one of the finest. With major trading in Africa and Britain, the economy flourished with brining many citizens a healthy income. With amazing advancements in culture and technology, Roman society was at its finest. During the Pax Romana, the Romans had 200 years of peace and good ruling by level headed dictators and emperors. Despite Rome’s greatness in all of these areas, Rome would eventually fall. Surprisingly all of these qualities that led up to a flourishing empire were the same ones that led to its demise.

The Sherman Anti Trust Act Of 1890 Essay - 1278 Words

Abbi Green Period 5 2016 Nov. 16 Anti-Trust The Sherman Anti-Trust Act of 1890 was passed to prohibit trusts, this was the first law passed by U.S. Congress to enforce this. This act was named after Senator John Sherman. Before this act was put into place, many other states had enforced laws very similar to the Sherman Anti-Trust Act. These laws were not perfect though, the large corporations had the majority of the economic power. Congress was not pleased with this, thus making the Sherman Anti-Trust Act. This act allowed Congress to regulate interstate commerce, outlawing monopolistic practices. If a person were to violate this act, he or she could be imprisoned for a year and fined five-thousand dollars. This law was successfully used to help Theodore Roosevelt during his campaign, â€Å"trust-busting†. Also, President Taft used the law to back himself up against the Standard Oil Trust and American Tobacco Company. The Standard Oil trust was when a board of nine trustees was set up to make all of the company dec isions , allowing the company to run as a monopoly. The Sherman Anti-Trust Act allowed both presidents to dissolve the trusts that were creating problems. On the other hand, the Sherman Anti-Trust Act had many holes, it did not have exact wording, therefore allowing companies to still control the majority of the producing and still get away with it. The Sherman Anti-Trust Act had substantial success, but was put to rest and replaced with the Clayton Anti-TrustShow MoreRelatedAnalysis Of The Sherman Anti Trust Act Of 18901682 Words   |  7 Pagesprices of their products.

Gladwell and the 10,000 Hour Theory - 564 Words

Practice isn’t the thing to do once you are good. It is the thing that makes you good. In the novel â€Å"Outliers, in the chapter â€Å"The 10,000 Hour Rule†, Gladwell introduces a theory that signifies that 10,000 hours is the approximate amount of practice time it takes for someone to become a master at something, and therefore likely to become a successful being. Gladwell backs up the theory by discussing a study that was performed around the 1990s by K. Anders Ericsson. In the study, Ericsson and his colleagues examined the long-term practicing habits of musicians at an elite musical academy in Berlin. Gladwell exposes the practicing habits of a few well-known successors to prove his theory such as, Bill Joy, The Beatles, and Bill Gates. Psychologist Michael Howe even applied the rule to Mozart, greatly considered a child prodigy. Bill Joy is probably the least known of the three successes, but that does not mean that the co-founder of Sun Microsystems who programmed UNIX and Java isn’t considered a great success among the members of the high tech crowd. Gladwell shows interest in revealing Joy’s story because there is relation between the two in the unique opportunities they had that were necessary for their success. Joy attended one of the only universities in the country that had a time-sharing system for computers, the computer system had a bug in it that unlimited his programming time and that the computer center was open 24 hours.

Their company motto sums them up pretty well; â€Å"serious about pies†. Jesters are New Zealand wholly owned and managed Pie Company. However the first original concept of it was started in Perth in 1997 when the idea of making the finest, healthiest pies in the market, was first created. Jesters pride their Jaffle Pie range to be of good quality, fresh, taste and health. Jesters are located in four cities nation wide which includes Auckland, Christchurch, Wellington and Dunedin. With the first being opened in 2002 at Lynn Mall shopping centre. The business is spreading fast with 34 stores being opened in Western Australia and many more planned. The reason for success Jesters feel is because of the niche $1 billion fast food industry, which they feel, is growing fast. Also because of the uniqueness of the brand and products for sale are new and interesting for the consumer. With over 15 varieties of pies Jesters feels there is something for everyone. The company also caters for your family or a party along with the sit in restaurant layout. The company promises to the customer†¦Ã¢â‚¬ you’ll never stop at one!† (Jesters, about Jesters, 2007) Analysis of Marketing Mix Product Jesters Pies is a unique company in the New Zealand market. Even though the product they are selling is just a pie, which can be brought from any bakery, it is the first to sell them in a fast food style restaurant. Jesters Pies offers 15 varieties of pies which appeal to a wide variety of customers. This is important because you want to cater to as many people as possible so you get more customers. Jesters also diverse their product from other pies by confidently saying that theirs are the healthiest and finest in the market. Another attribute of the pies is that the filling is low fat, lean meats and fresh vegetables, which you probably couldn’t say about your local bakery pie. The final attribute of the product is no artificial colourings, preservatives and MSG are used. This is a good look for the product as it has become so important for consumers in recent times to eat healthy, fresh food (Jesters Pies, 2007). Price Pricing is very important for a brand as it can create associations in the mind of the consumer. It can also be used to build brand equity. So a company needs to price its products correctly in order to get the most out of the consumer. Jesters’ pies are ranged from $3.50 to $4.10. With the $3.50 pies being the classic beef, mince and bacon and egg and the more expensive pies are the fancier ones with more ingredients such as the Popeye which contains spinach mushroom and feta. The pricing strategy they have I feel is good as the consumer gets what they are paying for. The pies are more expensive than the bakery, but are of much better quality and better ingredients are used. Distribution Channel Distribution can have a huge effect on the equity and success of a brand. Distribution is so important because it is the process of getting the product to the consumer. Jesters use a direct channel method to distribution where they sell their product straight to the consumer through their stores. This is probably the most effective way for a brand like Jesters .Jesters Pies stores can be found around New Zealand and in some parts of Australia. They are located in four cities in New Zealand. However all the stores in the Auckland area are found a long way out from central Auckland, with only one store being located in the CBD. However they do have stores located throughout the country so their distribution is pretty good. Promotion/Marketing Communication Promotion and marketing is very important for almost every brand in any industry. Without it you would not be able to get your product into the market and gain awareness from your potential consumers. Jesters have not done a huge amount of advertising that we could recall or find. From what we did find was mostly advertising for magazine and billboards. This could be one reason for the fact that their brand awareness amongst consumers is not very strong. Television is the strongest form of media and is the best for developing a brand image and creating awareness. However even without this the brand seems to be getting more popular which could be put down to things such as word of mouth. With a bit more promotion and marketing the brand could become very popular as it is a unique fast food outlet. Brand equity for Jester Pies Brand equity is an intangible asset that depends on associations made by the consumer. There are various perspectives from which to view brand equity. Brand equity just does not include the value of the brand, but it also includes the value of proprietary technologies, patents, trademarks and other intangibles like manufacturing know how (article 1). So in case of jesters pies, jesters jaffle pies are not oven baked like traditional pie, but they are cooked in a unique jaffle pie makers using ultra-thin light puff pastry and finest quality natural ingredients. Therefore the the difference in technical know how adds to the brand equity of the product. (article2.) Another way to measure the brand equity is the financial aspect of the brand. In this case one way to measure brand equity is to determine the price premium that the brand commands over a generic product. In case of jester’s pies, the pies are priced at $ 3.40 which is normally higher than most of the pies in the market place.

It can be how the brand makes them feel, what they think of the brand, what comes to their mind when they think of the brand or even what they do with the brand.

Jesters need to develop more awareness amongst its target customers. From people we have spoken to a lot of them were unaware of Jesters pies and the brand itself. In order to be successful brand awareness needs to be built up amongst the potential customers. †¢ Another issue gathered from the interviews was that the people who consumed Jesters said they were limited because of the lack of restaurants in handy locations. Perhaps to get more out there in the market they could locate some stores in key areas like around universities and more locations in the CBD How to cite Jesters Pies, Essay examples

Environmental Management for Anthropogenic- myassignmenthelp.com

Question: Discuss about theEnvironmental Management for Anthropogenic. Answer: Introduction The influence of Anthropogenic has rapidly changed the ecosystem of bay-delta over the past 150 years. Environment management plays an integral role in the protection of the environment as well as public health (Staley, Kean, Cannon, Schmidt, and Laber, 2013). The expectations of stakeholders and other business has increased from businesses and other public sector organization and they want them to be able to reveal that they are sensibly handling the impacts of environmental of their activities. Jervis Bay is the 102 square kilometer oceanic bay and village which is situated in the south coast of New South Wales, Australia. The resident of Jervis Bay is in fear their territory will be taken over by tourists and the native vegetation of them can be spoiled if the ACT is successful in managing responsibility for the area back to NSW. It is the report which will focus on the various environmental challenges of Jervis Bay Territory. Environment management challenges in Jervis Bay The region of Jervis Bay is situated in an overlap between the northern and southern climate zones. It has been analyzed that the range of habitats involve bay waters of varying depths, oceanic waters, ancient and recent dune system, coastal cliffs, forests, swamps, intertidal rock platforms, perched lakes and estuarine waters. Climate change and the delta ecosystem is the most horrible change which can destroy almost surroundings of it. Climate change impacts in the Jervis Bay The challenges of climate change are wider to confront the environment management and restoration of the Jervis Bay. The potential amendments in the climate and its variability are anticipated to profoundly affect the ecosystem and its physical and ecological structure along with the nature of water problems in Australia. The conditions of climate and variety of habitats are able to create an extremely rich and varied array of spices of wildlife both on the land and in the sea. It has been evaluated that there is a degree of uncertainty in the context of climate change which may influence the value of cultural, economic and natural of Jervis Bay. Hyder consulting is made a report on behalf of the Australian Government about the influence of climate change in the protected areas of Australia. As per the Hyder Consulting, the expectation of rising of CO2 levels to rise by 165 PPM until 2030 and 365 until 2070. This would be liable to increase the temperature of 1.3C respectively 4.0C, it would lead Jervis Bay to increase 35C by 3 days in 2030. There are impacts of climate change mentioned below in the context of Jervis Bay. Fire intensity and frequency Due to change o the climate change is increased the major risk of bush fires. It has been researched that the increased level of CO2 will be beneficial for photosynthesis. It is therefore anticipated that the increasing carbon levels will be beneficiary for undergrowth. It is fact that the rising temperature and enhanced evaporation will be able to reason of higher risk of fire in Jervis Bay. Wild fire would be able to be the reason of damaging to infrastructures and other facilities of the park which is related with the Jervis Bay. The impact of fire intensity and frequency over the Jervis bay is wider because there are major Booderee national park which involves vegetation communities that are particularly susceptible to enhance the chance of fire frequency involving swamp oak forests, dune system and rainforest. Due to fire intensity the rare species as well as other habitat will be vanished in a single fire (Lindenmayer, MacGregor, Dexter, Fortescue and Beaton, 2014). Sea level rise The increasing level of sea poses a high risk on the coast line of Jervis Bay. It has been consultant by hyder that the loss of costal habitats will be the reason of changing in foraging and diet habits. It would be liable to increase soil contamination which could lead to upper turbidity of sea water and can be the reason of adversely impact species of marine that is reliable eon the clarity of its habitat. There are so many effect of sea level rise and one of them is increased saltwater intrusion into freshwater parts. Due to increment of salt in the water force the habitat to move from here and habitats will shift or may be eradicates entirely (Porteous, 2013). The impact of it over the population of Jervis Bay is not good because the wider majority of the nations commercial and recreational fisheries are reliable on the marshes of coastal. Due to increment in sea levels in the Jervis Bay, the area which is built up behind these marshes will provide no chance for wetlands to migra te. The accumulated results will be millions of dollars in economy which may influence the livelihoods and sustainability of many communities of coastal. Storm intensity and frequency Strong winds and heavy rainfalls will provoke destructions alike to the ones reason by sea level rise. Rainfall is expected to become more variable for a long time of droughts. The severe storms also depictions cultural heritage to huge risk. Erosion and winds are capable to damage artefacts of culture. Climate change is being the huge reason for natural attributes of Jervis Bay. The fear of storm intensity and frequency has increased due to increment in the level of sea storm (Kirwan and Megonigal, 2013). Along with that there is the major role of soil erosion and sedimentation to be the cause of storm intensity and frequency. Higher temperature Temperature is considered as important indicator for fauna and flora to maintain the seasonable patterns. Higher temperature can affect the ecology of populations and the occurrence of suitable habitats for a range of species. Climate change bother the lifecycle of species in worldwide and being the reason of severe foraging issues when species that are lower in the chain of food are unable to find the food in right quantities at right time (Wolch, Byrne and Newell, 2014). The impact of higher temperature will have adverse impact over the populations as well as entire territory, the progress of the crops and eatable things could get adversely impacted. Changing Ocean Current Jervis Bay is impacted by the East Australian Current which moves southwards beside the Australian coast. It is anticipated that the change in climate will have influenced the ocean current. Some researchers have found that the East Australian Current will amend in a way that the growth of Grass Sea is facilitated (O'Riordan, 2014). It provides nutrients for marine life by cycling and that is why it is an important element for the food supply in the surrounding area of the Jervis Park. Coastal hazards The reason of coastal hazards is done by dynamic processes such as tides, waves, current and rock weathering along the coast. It would be disadvantageous for Jervis Bay because it involves beach storm erosion, costal induction and coastal recession. These hazards can be the cause of spoiling surrounding area of Jervis Bay. The major coastal hazards are in the context of Jervis Bay storm erosion, long term erosion and ocean flooding (Radosavljevic, Lantuit, Pollard, Overduin, Couture, Sachs, Helm, and Fritz, 2016). It has adverse impact over the population of the Jervis Bay because they have o be ready for sudden costal threats which may involve coastal storms, hurricanes, landslides and tsunamis that is why the population of that place have to be made a house of wooden and it should be heighted approximately 10 to 12 feet from the land. Environmental management system Environmental management system is relying on various process and procedures that are able to allow both the private as well as sectors of public to evaluate and decrease the influence other activities for improving the performance on constant manner. It has the management which focuses to motivate the organization of Jervis Bay to utilize EMSs to facilitate meet requirements of both voluntary as well as regulatory requirements in the zone of designing products and other sustainable practices. The rich marine life is able to attract large number of visitors in the area of it. It has been analyzed through operational plan for Jervis Bay Marine Park that the level of visitors has been enhanced with an increasing demand for ecotourism opportunities (Bruce, Albright, Sheehan and Blewitt, 2014). It should be the strategy of the environmental management system that discuss with Department of Defence in as per with the management arrangements so that in case of urgent requirement such as na tural disaster the defence team could protect many lives from bad situation. Implications and derived measures The amendments in climate are liable to bring the huge challenges for traditional protected areas and their management. Climate change will essentially lead to amends in the natural composition of Jervis Bay. The changes in climate are advantageous for some species and unfavorable for others. The nature of extinction cannot be avoided but other endangered animals of related park which is interlinked with Jervis bay could even advantageous from changed living conditions. It has been analyzed that in the past, biodiversity was usually seen not stable. The areas of protection were endorsed to preserve biodiversity in a certain region. The conservation goals are designed to promote ahead existence of natural composition (Cazenave, Dieng, Meyssignac, Von Schuckmann, Decharme, and Berthier, 2014). There were so many protected areas which were made with fixed goals such as the protection of specific species. Now the climate has changed in comparison of old days and obviously the biodiversit y structure will change in the future. It is important for the management of environment of Australia to determine whether they want to constant endeavoring to conserve the zone of population as it, knows the change is predictable or whether they keep focus on goals of conservation to meet future challenges. It is important for the Environmental management of Jervis Bay to understand the climate change implications in an adequate manner and execute the measurement of adaption to increase resilience. The fire management strategies should be implemented in continuous manner for the major landscape types in the Jervis Bay (Jones, Nyman and Sheridan 2014). The management should keep focus on the reduction of carbon footprint of the surrounding areas of Jervis Bay and its management (Thackway, 2014). The plan of this can be attained by minor measures such as switch to more efficient vehicles and use of renewable energy by solar PV system in the area of Jervis Bay. It has been analyzed fr om the operational plan of Jervis Bay that the plan has become ready to meet the objectives of conserving marine biodiversity, handling the process of ecological, providing chance to sustainable use of ecological and support to the public of Jervis bay. In combination with NSW Fisheries and National parks, evaluate the permit applications of research. The expert advice should be considered at prior basis in the concern of environmental issues. It is vital to develop hazard-resilient communities to make for the costal threats and the ability of the community should be enhanced to absorb influence and bounce back (Dasgupta, Hossain, Huq and Wheeler, 2014). It would be grateful to save the lives of many due to disasters and secure the economic stability of these communities. Conclusion It has been concluded that there is no protection guard to stop the natural disasters but by applying some strategies in daily life consumption can protect us from sooner natural disaster. The main topic has been discussed in the context of environmental challenges of Jervis Bay. It has been found that there are so many elements are liable to enhance the risk of living over there such as fire intensity and frequency, sea level rise, coastal hazards, higher temperature, change ocean current and storm intensity and frequency. The impact of them on the Jervis Bay and its surroundings has been mentioned in this report. It is vital for the environmental management system to keep focus on the protection guard from those environmental challenges. References Bruce, E., Albright, L., Sheehan, S. and Blewitt, M., 2014.
