Mobile Sensor Localization In Wireless Sensor â⬠Free Samples
Questions: 1.What research question does the paper address? 2.What was the conclusion of the research? Answers: 1. The research is being carried upon to have a proper insight to know whether the user pin can be stolen with the use of mobile users or it is just a hyped myth and has no practical grounds. The study is also based on the viability of the information leakage from these sensors, and further investigation is carried on to know have an in-depth analysis of the other sensors and functions[1]. The research question being pursued in this study is: as the mobile sensors are getting powerful and have access to more and more data about the user and its surrounding environment, the study is intended to know about the knowledge that the mobile users are having regarding this sensors. And also the study wants to investigate the level of fear people among people regarding these sensors which threatens the security and privacy[2]. 2. After an in-depth study, it was revealed that the access of mobile sensors with the use of Java scripts is limited to some sensors at a time. But the number is going to increase in the future with development and innovation. The users are least concerned about these sensors stealing the PINs or personal data. There are many proposals for developing a secure and usable solution waiting for future analysis. But according to this study, it can be concluded finding a proper solution for this is a bit complex. Thus, it can be relayed that an extensive study is needed to develop a permission framework which is secure and at the same time usable.

Learning English Essay Example | Topics and Well Written Essays - 1250 words
Learning English - Essay Example à I was born and raised in a Middle Eastern country. one of my uncles was a well-known businessman who had dealings with people from all over the world. As a child, I often heard him interact with them in a different language and at one time, I gained the courage to ask him what language it was. That was the first time that I encountered the word English and I became fascinated with it. à My uncle told me that English, like Arabic, was an international language which was used to communicate with people all over the world, no matter their nationality. à However, in my country, there was little opportunity for learning this language because the medium of teaching in school was mainly in Arabic. Despite this, I resolved that there would come a time when I would learn English and be able to communicate with people from other cultures. My opportunity came when my application to Middle Tennessee State University was accepted and became the turning point because of my desire to learn English came to be satisfied. In America, I met an individual who would not only teach me the English language but also make it possible for me to gain some proficiency in it.à My two friends, Abdullah and Mustafa, and I started taking English classes with Irving Penzo, a renowned English teacher who helped the three of us excel in the language. from the beginning of our classes, we all took to him because he was not only jovial but also a man who was dedicated to the welfare of all of his students.
