	Hair analysis can demonstrate the content level of the heavy mental and essential elements in human body. [19] The different value of some essential elements in hair may be correlated with nutritional status and diseases, such as calcium (Ca), chromium (Cr), zinc (Zn), copper (Cu), and selenium (Se). The high values of some elements such as lead (Pb), arsenic (As), mercury (Hg), and cadmium (Cd) in hair can indicate the intoxicating phenomenon.

	The living environment can affect the content level of elements in human body. This effect not only caused by polluted water and food, but through the injury and radiation. Trace elements values in hair can reflect the source of behaviors including the diet hobbies, smoking and medication. Human absorbs pollution source by different ways such as oral, breath, injection and radiation. These contaminants stored in different body organs and tissues can affect human health. Hair is a good indicator of environment change. Normally, it shows the variation of trace element in human body as the hair growth.

	As Professor Derek Abbott has been following this case for a long time, there were several project groups that had been working on this unsolved case from 2009 to the present. The conclusions drawn out by previous groups are: the code is unlikely to be generated randomly, the code is unlikely to be initial letters from words, the book Rubaiyat of Omar Khayyam was unlikely to be used as a one-time pad for encryption, the original language of the code is likely to be English, the code is unlikely to be initialisms extracted from poems, the book Rubaiyat of Omar Khayyam was not used as a straight substitution one-time pad for encryption and the code was not created using the Rubaiyat of Omar Khayyam as a one-time pad.[7][8][9][10][11][12]		As Professor Derek Abbott has been following this case for a long time, there were several project groups that had been working on this unsolved case from 2009 to the present.

	In addition to police men’s investigation, there already have several academic studies. Prof. Derek Abbott has worked on this case for more than 2000 hours. [9] His team took the hairs from Somerton man’s plaster cast and recorded elements data by ICP-MS. Since 2009, it had become a final project for the University of Adelaide students and some students had participated this project. In 2013, the project group plot some Somerton man’s hair elements’ content figures and compared with control samples. [6] They have analysed the differences between Somerton man’s hair and control samples. However, those hairs’ data were all got from glass test. In this project, we redo the analysis based on the data that got from quartz test. In addition, we will compare those two different data figures. However, the new data should not be compared with old directly due to different drift values. The new data will multiply a constant which is got from the glass test remainder that is a bit rest of Somerton man’s unburned hair. Besides, the different year of plasters needed to be considered as well.		In addition to police men’s investigation, there already have several academic studies.

	As the figure above displayed, the code consists of fifty capital letters. For the sake of getting as many samples as possible the six crossed out letters are also included. There has been a dispute about the ambiguous “M” or “W” letters appear in the code, as a result two different versions of the code was tested (one with “M” and the other with “W”).

There has been a dispute about the ambiguous “M” or “W” letters appear in the code, as a result two different versions of the code was tested (one with “M” and the other with “W”).
	After postmortem, the coroner picked some information from this dead man, such as the heart was of normal size and the death time was around 2 am of the found day. Besides, the coroner figured out that approximate three to four hours before death the man ate a pasty as meal which pathologist Dr. Dwyer suggested some poisons causing the man’s death. But the pasty should not be the source of poison through further research. Finally, after a series of investigations, the coroner still could not tell any conclusion about this man’s identity or cause of death and the dead man’s body was buried in Adelaide's West Terrace Cemetery in 1949. It became one of the Australia's most fascinating cold cases.

It became one of the Australia's most fascinating cold cases. [2][4][10]
	In order to continue the study of this case, a plaster cast of Somerton man was made in 1949. The hairs which were extracted from Somerton man plaster cast and other six different students are used for spectral analysis. [9] Hair data is recorded by Inductively Coupled Plasma Mass Spectrometer (ICP-MS) and this instrument is effective for micro-sampling of solid material for trace elements and the analysis of predominantly cation. [1] For collecting data, the hairs were burned by laser. Then, the instrument measured the levels of different isotopes and the relatively values of elements. After testing, the comparison for experimental results between Somerton man and six other different students can be processed.

	In this project, data comparison and statistical data analysis techniques were applied to crack a set of mysterious code extracted from an unsolved possible murder case. Data comparison is a branch of computer science, which calculates the differences and similarities among data objects, personified in this case: among a large amount of strings. Data analysis is to extract useful information from data to help generating conclusion and giving supports to it. The goal of this project is to find out in which language the code was written.

	Initially, the contributions accomplished by previous project groups were reviewed and an insight was found to be a perfect beginning point of this project: it was suggested and supported that the code was very likely to be initialism in English, meaning that the code consists of first letters of a set of English words [1]. It was an amazing guess but unfortunately two problems were found after the reviewing of their works. Despite that the method applied to calculate similarities was lacking of convincing, it had not been updated for a long time. Besides, the test numbers were insufficient to draw out any conclusions.
