EXERCISESI. Match the following items and the text. They refer to preparing and sending the paper.1. Choice of the journal ………………………….2. Guidelines …………………………3. Length of the paper …………………………4 . Cover letter ………………………….5. Declaration ………………………….6. Confirmation of receipt ………………………….7. Review process ………………………….a) The usual length of a paper is about 6,000 to 9,000 words, i.e., about 6 to 9 pages (however, mathematics papers can be longer). Do not exceed this figure because some journals may return the paper for shortening. One journal page = 1,000 words.b) The journal´s editor will confirm that the contribution has been received and will forward it to a reviewer who will then judge the quality of the paper and often also your English.c) Almost all journals now appear also in electronic form. Your supervisor will know which journal in your field is the most suitable for you. You can also find one when searching for papers by keywords. However, not all the papers you find in this way give the name of the journal.d) All journals inform about their publication policy on their web pages. They give detailed information to authors on how to prepare a paper for submission and even offer a form/template for electronic submission.e) Some journals will publish a paper only if a statement is attached saying that the paper presents an original contribution to the researched problem and that the facts have not been published elsewhere. (See Exercise XXXIV.)f) To submit the paper, check if the journal accepts papers only in electronic form (which is becoming prevailing practice) or if a hard copy is to be sent as well. It is polite to accompany the paper with a short cover letter (sometimes a blank space is left on the submission form). (See also Guidelines for Academic Writing: How to write a formal letter).g) After the paper has been peer-reviewed, you will most probably be asked to revise some sections or parts and to work on your English, i.e. correct language errors, change some formulations or even the style, as required by the journal. When you have done that, send the paper back and wait for the announcement that it has been accepted for publication. TitleII. What errors can you find in the following titles?1.

Areview of the literature shows that simulation and modelling have not been extensivelyapplied in just-in-time (JIT) manufacturing environments. Also there remains a lack of a comprehensive mechanism to identify the most significant JIT drivers for the purpose ofsystem process optimisation. The prime objective of this study is to close this gap byapplying computer based simulation tools and linear mathematical modelling to identify theimpact of selected key JIT parameters on performance in an automotive component—manufacturing environment. Research shows that variables such as inconsistent task distribution, variation on operator performance, misconception of total quality managementphilosophy and lack of set-up time elimination plans disrupt ideal JIT production. In thisstudy, ProModel simulation and modelling software is used to model and simulate different experimental scenarios in order to understand and quantify the impact of selected input keyJIT variables on objective functions (i.e. process time and takt time). The outcome is a robust mathematical model that highlights the significance of JIT drivers in the manually operatedmixed-model assembly lines.(From Robotics and Computer-Integrated Manufacturing, vol. 24, 2008, p. 735)Which lines describe1. the topic ………………………………………………………………………………………………………………………………..2. the background ……………………………………………………………………………………………………………………………….3. the method(s) and approach ……………………………………………………………………………………………………………………………….4. the results ……………………………………………………………………………………………………………………………….5. the conclusion …………………………………………………………………………………………………………………………………….Give the numbers of the lines and the first words of the first sentence(s).VII. The paragraphs in the following abstract have been scrambled.i. Rearrange them so that they form a cohesive text.ii.

A silicon tube (inner diameter 4mm) with one end plugged by a highly sensitive pressure sensor and the other end capped is sandwiched between two rigid boards and placed on the ground at the entrance gate of the border.d) This paper describes a novel method for detecting the presence of a person hiding in a car. One of the important strategies of homeland security is border control. In particular, strict and effective monitoring to control illegal immigration is a key strategy for maintaining public safety and a healthy local economy, and is essential for preventing the entry of terrorists.e) Here, we propose a heartbeat detection filter robust against disturbances but sensitive to the heartbeat signal and an index to discriminate between the presence and non-presence of a person, and we present the experimental results obtained using the proposed method under various disturbance conditions.f) When one wheel of the car is on the board and the engine is stopped, the pressure sensor can detect human vital signs such as heartbeat, which cannot be concealed.(From IEEE Sensors Journal, vol. 11, no. 9, Sept. 2011, p. 1872)i. 1. ….. 2. ….. 3. ….. 4. ….. 5. ….. 6. …..ii. ………………………………………………………………………………………………………………………………….…………………………………………………………………………………………………………………………………VIII. Imagine you are someone interested in renewable energy sources, especially wind power. Read the following abstract written by a student and say whether you would/would not like to read the whole paper and why. Is there any information you miss? Comparison of the Abstract with the Conclusion might be helpful.AbstractWind power plants must provide the same power quality as other power plants. Special attention is paid to the requirement of supplied energy stability because wind power plants are connected to the grid. It is very important to understand the sources of disturbances that affect power quality. The main parameters monitored are frequency and voltage, which have to be kept as stable as possible. The current and power can also be measured. However, the relationship between voltage quality and energy quality is unknown.Now read the conclusion.ConclusionFrom the measurements described above it is obvious that the wind turbine operation agrees with the EN 50160 standard. The only problem arose with flicker as the measured data were not realistic. Consequently, flicker will have to be measured again. All the other parameters did, however, meet the standard.………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………IX.

The regional setting is dynamic.2. Internet use and the general demand for information technology (IT) hardware and services in the Middle East are growing, with a projected market value of 8.9 billion dollars by 2005 [1].3. Egypt, Saudi Arabia and the United Arab Emirates (UAE) accounted for about 59% of 2001 demand and as much as 64% of the future forecast.4. In 2001, the launching of Egypt´s first free Internet service provider Noorillustrated wide commitment to market opportunities. 5. It is no wonder that the Internet and burgeoning world of e-commerce and Net-enhancement are viewed as engines of economic growth for Egypt in the 21st century, and why Arab countries such as Egypt are exemplars of how to leapfrog [2] into the IT era [3]. 6. While it is easy to ride this wave of enthusiasm for innovations such as the Internet, failing to understand the factors that influence diffusion at the micro level is still a threat. 7. Past experience shows that technology diffusion is not a straightforward process [4]. 8. Based on prior theoretical work, our field study gathered quantitative and qualitative data from Arab knowledge workers and top and middle-level managers, nearly all of whom were Internet-savvy. 9.

Following this, the flow rate was reduced to 100sccm and the humidity was increased by 825 ppm every 60 minutes, for seven hours. Theresults of this experiment are depicted in Fig. 4.With the initial application of 825 ppm humid air, the normal frequency shift of the pureSH-SAW resonator is 11.9 ppm. For each subsequent 825 increase in humidity thereafter, the normalized frequency shift changes by less than 5.1 ppm.(From IEEE Sensors Journal, vol. 11, no. 9, Sept. 2011, p. 1772)2.Fig. 4 shows the sensing device used in the verification experiments. Forty-eightrectangular shaped spacers with dimensions 400x30x10 mm are set on the base board. Thespacers are made of a soft, sponge type material.

Fig. 11(e) showsthe results when no one was in the car and there were either weak or strong disturbancevibrations. 4. The distribution is similar to that shown in Fig. 10 when no one was in thesedan-type car. 5. The most frequent distribution is concentrated around F = 0.015. 6. As canbe seen from the histogram in Fig. 11(a)-(e), index F decreases in proportion to the distancebetween the person´s position and the sensing device board. 7. This is because the signalattenuates in proportion to the distance. 8. However, when a person is in the car, even aslight body movement provides a greater value of index F. 9. Thus, the distribution is morewidely spread than when no one is in the car. 10. Even with the difference in histogramdistribution due to the different cars and hiding positions, there was still a clear difference indistribution when people were in the car and when no one was in the car. 11.

What were the main results of your Master thesis? Summarize them in five to tensentences.DiscussionXXIV. Read the extracts from the Discussion below. What is their purpose?Development of Sensing Device to Detect Persons Hiding in a Car1. From the histograms in Figs. 9-11, we considered how to set a threshold T h for judging the presence or non-presence of a person hiding in the car. …………………………………….. . For both the sedan and the camper, if index F is less than 0.12, there is a 90% probability that no one is hiding in the vehicle.2. The results do not perfectly discriminate between the presence and non-presence of a person due to the disturbance from the dynamic pressure of wind and ground vibration. If the inspection was conducted in a closed area, the judgment accuracy would be improved. Nonetheless, by identifying the high probability of a concealed person, a more detailed inspection could be carried out, which would make the inspection procedure more efficient.3. Regarding detection time, the X-ray method requires shorter time than this system, but [6] indicates the danger of using the X-ray method for finding illegal immigrants because of their exposure to X-rays. This system needs more detection time than X-ray because the system requires the drivers and all fellow passengers to get out of the vehicles, but compared with the hands-on searching by border officers, the system can reduce the detection time without the dangers such as the exposure to radiation.(From IEEE Sensors Journal, vol. 11, no. 9, Sept. 2011, pp. 1876 – 1878)1. ………………………………………………………………………………………………………………………………………..2. ……………………………………………………………………………………………………………………………………….3. ……………………………………………………………………………………………………………………………………….

First read the extracts from the following Introduction. Then study the Conclusion. Compare the extracts with the Conclusion and say whether the Conclusion provides answers to the problem as stated in the Introduction.Development of Sensing Device to Detect Persons Hiding in a CarIntroductionIllegal immigration from neighboring countries is a serious problem ………………………………. . Accurate devices to quickly and easily find people hiding in vehicles are necessary to maintain strict border control as well as make the illegal immigration procedure more effective.Generally, a border officer checks the inside and/or outside of a vehicle to determine if anyone is hiding there. ……………………………………… . Alternatives to this manual method have been considered, such as the X-ray equipment …………………………………… [4] and …………………… …………………… [5]. However, these methods require a high initial cost …………………………………. . Moreover, the danger of using the X-ray method for finding illegal immigrants is indicated because the illegal immigrants would be exposed to X-rays [6]. A simpler method which uses microvibrations to detect a concealed person has been proposed [7]. We also proposed a similar method ………………………………. [8].These methods, however, are sensitive not only to human microvibrations but also to external disturbances such as ground vibration and wind force acting on the vehicle.This paper describes a novel pneumatic method that uses silicon air tubes and a low-frequency condenser microphone as a pressure sensor highly sensitive to the heartbeat signals of a person hiding in a vehicle but robust against external disturbances such as。
