Week 4 Identifying the right approach

  1. Is this a good question? (problems might be e.g.  assumptions, ambiguity, too broad)
  2. How would I gain/gather that knowledge/evidence? (e.g. interviews, survey, experiments)
  3. Who did the work/research? Do they seem credible

Here is the questions:

Samsung Galaxy S7 Edge and iphone 7 which is better

(1)This is a difficult question to answer, because the two phones are installed different systems and  the GPU and RAM are also different,  this contrast is not good.

(2)Think of the results, you must get these two phones and  to do test in all aspects at the same time

(3)I found a test video about those two phone.

In this test, the staff open a few same APP on the two phones. In the test, the man to determine which phone is better according the speed of opening those APP and the speed of running the APP. Looks like this is a good test, but I think this method do not followed sufficiently rigorous. First, the power of the two phones is different, this may affect the test. Second, the researcher did not specify the information before the two phones were tested. ( eg: Have these two phones  been used in the near future? It will affect the test) Finally, he did not test the defense of the two phones. The result is I do not believe this method.

Week 11

My aim is exploring my ideas and thoughts on what might make a good project and what we need to do to create a proposal that will be accepted in this week.

Short description of area of IT that interests you or you want to know more about.

1.Why is it interesting to you?

Website design has always been my most interesting part,  because I think in the design  the site, I need to discuss his requirements about this site, I like the process that step by step to complete the  customer’s needs, and build a site do not need to use difficult programming language, such as C + +.

2.Three things you know about it

(1)Design the site must communicate with the customer.

(2)Web site is not limited to browsing on the PC, I need to consider the phone or tablet computer

(3)Website can be modular or customizable

3.Three things you believe about it

(1)Design a good site not only need it knowledge, but also understand typography

(2)I believe that the site can not be built in a short time

(3)The customer’s opinion is important

4.Three things you don’t know about it 

(1)I’m not sure what software is the most suitable for me to build a website.

(2)I do not know how to make a website  perfect  compatible PC,  phone and tablet computer at the same time.

(3)I do not know the influence of Android system and IOS system for the site.

Go and see if you can find an online resource about it and post url. This could be a forum? facebook group? linkedin group? or a good blog?

Week 7

This week  the web teacher  lets us to complete a group cooperation. The goal is building a website according analyze the needs of NDS company from the customer’s letter. So, my team members share a blank Google document for each team member. This document could be edited by anyone who have any ideas. I really have no idea about building a website, so I discussed with group members about their ideas.

After the analysis, we got the conclusion: NDS is a development business specialising in databases. We are involved in providing specialist DBA and database scripting services in SQL Server and Oracle (to a lesser degree). We also provide database and UI development for environmental data such as the Department of Conservation’s monitoring data – where data quality must meet the rigours of science analysis. The data here is being analysed by PHD level statisticians using R. As an aside to this, we are extensively involved in the migration and ingestion of data from disparate sources into a single schema

RES 701 WEEK 2

This week, the teacher gave us a few questions, let us and the class team members to discuss. I am interested in these two questions.

1.What is “truth”?

2.Einstein: “Reality is fantasy, though it is a very enduring one” Einstein. What does this mean to you?

What is “truth”?

Nowadays network technology is well developed, people can contact people who are easy to communicate from all over the world, but there are shortcomings: people get a lot of different “truths” from the Internet.

I think the truth can refer to the past and now being validated and neutral information, in scientific terms that can prove the concept. Rumors can not be used as facts. Also the truth is the real situation of things, including things, events, that is the objective objects and phenomena.

Einstein: “Reality is fantasy, though it is a very enduring one” Einstein. What does this mean to you?

In fact, I was scared after reading this sentence. I think the meaning of this sentence is: All the truth things are actually human understanding and they are not true. This sentence let me to recall a movie ‘Inception’.  The film describes a person living in the world, everything is very real, the terrible thing is  he knew he is in his dream at the last.I think Edison’s sentence is wrong. I think the truth is not fantasy. For example, a worker gets $ 500 salary  on last weekend so the truth is his salary is $ 500 a week, it can not be a fantasy.

Week 8 Simulated motorcycle accident

Introduction

In China, motorcycle accidents frequent, in the accident motorcycle driver a passenger vulnerable to serious injuries. After the accident, the scene is usually more chaotic, if there are two motorcycle victims, it is difficult to identify who is the forensic motorcycle driver, so the police and the judge is difficult to determine the responsibility of the victim. The author established two typical motorcycle accident cases, and its analysis. Analyzes the movement and the degree of injury of the motorcycle driver and the rear passenger during the collision. When the motorcycle hit the car, the driver and rear passengers were thrown out of the inertia. The distance between the driver and the rear passenger being thrown away and the degree of head injury. The results can help forensic experts deal with similar motorcycle crash accidents. The authors use numerical algorithms (eg, modified Euler or Runge-Kutta) to predict the motion of systems of bodies connected by kinematic joints, based on initial conditions and the inertial properties of the bodies.

 

Accident one, the motorcycle suddenly hit the left rear of a car, two people on the motorcycle were thrown out, the victim A from the motorcycle 715cm, the main fatal injury from the head and brain, died on the spot. Victims B from the motorcycle 105cm, head limbs and other parts of the injury, survived in the hospital. The police think that the back-seat occupant on the motorcycle might be thrown farther away from the motorcycle than the motorcycle driver when the collision happened, so it can be assumed that B is the driver and he should be responsible for the accident. But B denied that he was a driver, and did not plead guilty in the court, so the police cannot be absolutely confirmed.

 

Accident two, at the crossroads of a moped in the red light when driving continued to lead a car from the right hit the motorcycle. A victim’s right leg and head were fatal blows in the accident, were taken to hospital for treatment, and unfortunately died in the hospital. Another victim escaped from the location of the accident. Forensic that the deceased right leg is broken by the front of the car, if he is the driver, the legs will not be hit, so another person is the driver. But this assumption is determined before the accident can be judged.

 

The author uses the computer simulation method to restore the process of these two accidents, the results are the same as the previous assumptions, to determine the previous assumptions. The MADYMO [6-9] (mathematical dynamics model) used in the research has been widely used for accident reconstruction and that involving a lot of transport, such as motorcycles, cars (Lei, Xian-Long, Xiao-Yun, Jie, & Yi-Jiu, 2008).

 

 

 

 

Review

The next step, I will make a detailed evaluation of this paper. The main comment about the credibility of the paper, the help for people, the author’s research methods and results and what I can learn from this paper.

 

What is the title and what does the title tell you about the paper?

The title of this paper is ‘study of batter combining computer simulation in motorcycle-car collision accidents’. I can get some information from this title. The first is the author of this paper to study the two motorcycles accident. The second, author using the research method is the computer simulation method.

 

Who is the paper written by and do they seem credible to you?

The author of this paper is Guo Lei, Shen Jie, Zhang Xiao-Yun, Jin Xian-Long. In fact, I do not understand these authors at all, but at the end of the paper, these authors are from Shanghai Jiaotong University and this paper published in Elsevier Ireland Ltd. Shanghai Jiaotong University is a famous university in China, Elsevier is one of the world’s largest medical and other scientific literature publishers, so I think this paper is credible to me. In addition, I searched a paper that is author’s reference. ” Injury patterns associated with drove motorcycle crashes” gives the result: in the motorcycle accident, the rear passengers are more likely to be seriously injured lead to death. This conclusion is very close to the paper I research.

 

Does it have a helpful abstract? Give reasons for your answer.

The abstract of this paper is very useful. In the beginning of the summary to write in this search, the author is using a computer simulation method to study, to solve the problem faced by forensic experts. In addition, abstract includes the approximate research process and the final results of the study, and this result can help forensic experts in the future to resolve a similar collision accident.

 

What did the author(s) do in their research, what research approach and what method(s) did they use?

In the research, the author refers to a lot of articles on computer simulation and motorcycle accident papers. The author detailed records of the computer simulation out of the car accident scene characteristics and data, and the simulation of the accident scene and the reality of the accident scene comparison, and finally concluded.

The authors used multi-body dynamics method is one of the most useful computer programming methodologies in the world, and it can simulate the dynamics response of complex multi-body systems.

 

 

 

Do you think the method(s) they used to be appropriate to the question they were asking? Explain why or why not.

I think the author’s method is very suitable for their problems, because when a car accident occurs usually do not record the process of car accident video, it is difficult to get the results in the car accident examples, computer simulation is a good choice, and can save cost. In addition, the authors use MADYMO [6-9] (mathematical dynamic model) is a software of the multi-body dynamics technique which has been most widely applied in injury biomechanics and accident reconstruction [10-12] have many means of transport such as Cars, motorcycles and bicycles.

 

What results does the paper report?

 

The paper describes the author after the search has got the following two results:

 

  • In the computer simulation of the accident scene, the driver from the motorcycle 120cm. Rear passenger from the motorcycle 617cm. Comparing to the driver, the rear passenger was thrown very high, so there is no friction or collision with the front of the car so the drop point is far away from the motor, head suffered heavy injuries when landing, leading rear passenger to death. Therefore, concluded, the victim B is the driver and the victim A is the rear passenger in the accident one
  • In the computer simulation of the accident scene, because the rear passenger want to keep a stable sitting on a motorcycle, the rear passengers put his legs on the pedal on both sides of the motorcycle, resulting in the rear passenger’s legs cannot escape when the car hit the motorcycle so his legs were broken. However, the driver was lucky because the driver put his legs on the big pedal of the mopeds, so he was safe to escape the accident. Thence, the man is the driver who escape the accident and the other person is the rear passenger.

 

Was the paper worth reading? Give reasons for your answer.

I think this paper is valuable to me because I like riding a motorcycle and usually riding very fast. After reading this paper, I clearly realized the process of the accident, If I met a motorcycle accident unfortunately in the future, I can handle it better. Besides, in these two motorcycle accidents, the victim did not bring the helmet is also a important cause of death and the author mentioned that if the victim with a helmet will not die.

 

Do you believe the results/findings or the paper? Give reasons for your answer.

The answer is yes. Because I hold the brakes of front wheel with force when I ride the motorcycle, the motorcycle ‘s rear wheel almost lifted to lead to roll. If in the motorcycle accident and there have rear passengers, the rear passengers will throw away very far by the power of the rear wheel.

 

What did you learn from reading the paper?

After reading this paper, I learned that in a motorcycle accident, the rear passengers received more serious damage than the driver. In addition, I have always thought that the results of computer simulation methods are not correct, and now I admit that this method is helpful at some time in the research.

Credible evidence

Credible Evidence

 

This week I was looking for credible evidence and I have one questions: What is the best CMS?

What is the best CMS?

At the first I tried to search for this question in Google Scholar, but I could not find it because no one would be bored to write this question as an academic paper. Therefore, I found some information on a forum.12.PNG

Link:  https://www.quora.com/profile/James-Ankobia#

How it was found: Search on Quora

When it was written: 7-6-2017

Who written it: James Ankobia

What kind of publication: Forum

Do I think it is credible?

No, I think his article is not convincing. I can only judge the credibility from the content of his article, because most of the things in the forum are not authoritative and I do not know the author. Article showed WordPress share is the highest in the global market, so I search it on W3Techs, the site shows me the first is WordPress (59.1%) and the second, JOOLMA (6.9%).

Although he listed the data is correct, but only the data is not enough. He did not say the advantages of WordPress just say a lot of people use him, I think the user cannot prove that WordPress is the best CMS.

 

 

Then I found some information on a blog.

Do I think it is credible?

 

Yes! I totally agree with his opinion, because I installed WordPress on my computer last week and used it. WordPress was very easy to install and use, user did not need professional computer knowledge at all. The most important thing is software support. I asked a question in the community and got a reply soon. Therefore, this is a credible evidence.

Week 5, Free topic

This week the blog no topic, so it is quite simple. Therefore,I looked the New Zealand customs law, because I want by something from China and I am not sure what is banned by the customs. I searched the information on the nzpost official website.

The website mentions that there are three kinds of results, the first is not allowed to enter New Zealand, the next is the entering New Zealand after pay tax, the last one is directly into New Zealand. Due to the display of many types of items so I did not carefully read, I only looked I am interested. I was lucky because I wanted my parents to post something to New Zealand without any violation. I let my parents post a headset that I did not found in New Zealand. The law provides for the import of electronic products, the electronic products can only enter New Zealand after the battery removed from the product and specially packed, if the items include the battery. Therefore, I do not need to worry, because there is no battery in that headset.

Finally, I found that the laws of New Zealand and China’s customs were essentially the same after the research.

RES 701 Secondary Research Week6

 

This article describes what is Secondary Research. Secondary Research means people to do a further analysis and summary on Secondary Sources that people already get and the Secondary Sources could include previous research reports, newspapers, magazines and journals as well as government and NGO statistics.

Firstly, I think Secondary Research is very useful for IT even every research. For example, if I need built a website for a financier I can research the stock market data online and import his website, that will Save much my time and energy. Secondly, they are some advantage of Secondary research: First, do not need to cost too much money and time to collect data. Second, researchers could concentrate on analyzing the data so the efficiency is very high. Third, researchers can do a compare with data from different ways to get a great result. In the other hand, there are also some problems researchers cannot be avoided: Sometimes the Secondary Sources is inappropriate for present research even cannot find the data. Moreover, the reliability of Secondary Sources may vary over time or not accurate and objective.

At last, I know what is Secondary Research and it is an effective tool to analyze reports that people can gain accurate information.

RES 701 WEEK 3

I think ontology means that people discuss the truth of a thing itself. In general, people will discuss the characteristics of this thing so the ontology is very close with research.

Epistemology is a philosophical doctrine that explores the relationship between the nature, structure, cognition and objective reality of human cognition, the premise and foundation of cognition, the process of cognition, development and its law, and the truth of knowledge.

Ontology is objective and epistemology is abstract.  In a research context, if people can use these two methods to analyze one thing clearly, people will get a answer quickly.
