Fly to minimise delays

by | Mar 4, 2023 | Computer science

 

The 2009 ASA Statistical Computing and Graphics Data Expo consisted of flight arrival and departure
details for all commercial flights on major carriers within the USA, from October 1987 to April 2008.
This is a large dataset; there are nearly 120 million records in total, and takes up 1.6 gigabytes of space
compressed and 12 gigabytes when uncompressed. The complete dataset along with supplementary
information and variable descriptions can be downloaded from the Harvard Dataverse at
https://doi.org/10.7910/DVN/HG7NV7
Choose any subset of (at least two) consecutive years and any of the supplementary information
provided by the Harvard Dataverse to answer the following questions using the principles and tools
you have learned in this course:
1. When is the best time of day, day of the week, and time of year to fly to minimise delays?
2. Do older planes suffer more delays?
3. How does the number of people flying between different locations change over time?
4. Can you detect cascading failures as delays in one airport create delays in others?
5. Use the available variables to construct a model that predicts delays.

 

 

Sample solution

Dante Alighieri played a critical role in the literature world through his poem Divine Comedy that was written in the 14th century. The poem contains Inferno, Purgatorio, and Paradiso. The Inferno is a description of the nine circles of torment that are found on the earth. It depicts the realms of the people that have gone against the spiritual values and who, instead, have chosen bestial appetite, violence, or fraud and malice. The nine circles of hell are limbo, lust, gluttony, greed and wrath. Others are heresy, violence, fraud, and treachery. The purpose of this paper is to examine the Dante’s Inferno in the perspective of its portrayal of God’s image and the justification of hell. 

In this epic poem, God is portrayed as a super being guilty of multiple weaknesses including being egotistic, unjust, and hypocritical. Dante, in this poem, depicts God as being more human than divine by challenging God’s omnipotence. Additionally, the manner in which Dante describes Hell is in full contradiction to the morals of God as written in the Bible. When god arranges Hell to flatter Himself, He commits egotism, a sin that is common among human beings (Cheney, 2016). The weakness is depicted in Limbo and on the Gate of Hell where, for instance, God sends those who do not worship Him to Hell. This implies that failure to worship Him is a sin.

God is also depicted as lacking justice in His actions thus removing the godly image. The injustice is portrayed by the manner in which the sodomites and opportunists are treated. The opportunists are subjected to banner chasing in their lives after death followed by being stung by insects and maggots. They are known to having done neither good nor bad during their lifetimes and, therefore, justice could have demanded that they be granted a neutral punishment having lived a neutral life. The sodomites are also punished unfairly by God when Brunetto Lattini is condemned to hell despite being a good leader (Babor, T. F., McGovern, T., & Robaina, K. (2017). While he commited sodomy, God chooses to ignore all the other good deeds that Brunetto did.

Finally, God is also portrayed as being hypocritical in His actions, a sin that further diminishes His godliness and makes Him more human. A case in point is when God condemns the sin of egotism and goes ahead to commit it repeatedly. Proverbs 29:23 states that “arrogance will bring your downfall, but if you are humble, you will be respected.” When Slattery condemns Dante’s human state as being weak, doubtful, and limited, he is proving God’s hypocrisy because He is also human (Verdicchio, 2015). The actions of God in Hell as portrayed by Dante are inconsistent with the Biblical literature. Both Dante and God are prone to making mistakes, something common among human beings thus making God more human.

To wrap it up, Dante portrays God is more human since He commits the same sins that humans commit: egotism, hypocrisy, and injustice. Hell is justified as being a destination for victims of the mistakes committed by God. The Hell is presented as being a totally different place as compared to what is written about it in the Bible. As a result, reading through the text gives an image of God who is prone to the very mistakes common to humans thus ripping Him off His lofty status of divine and, instead, making Him a mere human. Whether or not Dante did it intentionally is subject to debate but one thing is clear in the poem: the misconstrued notion of God is revealed to future generations.

The 2009 ASA Statistical Computing and Graphics Data Expo consists of flight arrival and departure details for all commercial flights on major carriers within the USA, from October 1987 to April 2008. For this analysis I have chosen a subset of consecutive years from 2006-2007. Additionally, I will be using supplementary information such as origin/destination airports, scheduled departure/arrival times and delay durations among other variables provided by the Harvard Dataverse.

In order to identify when is the best time of day, day of the week, and time of year to fly in order minimize delays we can start by looking at how average delays are distributed across various categories such as hour day month . Through data visualization techniques like box-whisker plots histograms scatterplots could get better understanding which factors tend lead most consistent least varying levels flights’ timings compare performance different airline companies during certain seasons.

We then take closer look relationship between age planes (measured number cycles flown) rate delays they experience over period sample. This would involve further analyzing data set plotting graph showing relationship between these two variables find out more insight into correlation any exists between them.

Next , create map display movement passengers flights originating different parts country based on available variables mentioned above determine whether there noticeable fluctuations over course sample could related changing economic climate political situation fluctuation procurement cost fuel etc.. Moreover we can conduct detailed investigations reveal potential cascading failures whereby delays one airport result same occurring another station due chain reaction caused ripple effect around system .

Finally , use all relevant parameters dataset construct predictive model able accurately predict pote​‌‍‍‍‌‍‍‌‍‌��̶̷͇͇͟n​tial level delays given combinations origin destination hours days months taking into account seasonal trends changes external environment as well weather conditions which also common cause disturbances air traffic control operations.
