1. The world is small and the city is big.People who lack for luck would not see one another again for the rest of life.
2. If you've found meaning in your life, you don't want to go back.
3. Happiness, never shortcut, also not perfect, only to run, only by the heart.
4. Everyone would get tired.Nobody can take the sorrow for you.We some time need to grow up by ourselves.
5. In the eternal universe, every human being has a one-off chance to live—his existence is unique and irretrievable, for the mold with which he was made, as Rousseau said, was broken by God immediately afterwards.
6. When you are young, you should not meet the people who are so amazed.Otherwise,the rest of your life is regrettable. ”
7. We live in this world when we love it.
8. You can change your life if you want to. Sometimes you have to be hard on yourself, but you can change it completely.
9. You never know how strong you really are until being strong is the only choice you have。
10. If you can't fly then run, if you can't run then walk, if you can't walk then crawl, but whatever you do you have to keep moving forward.
11. All success comes from tireless effort and pursuit, and all happiness comes from daily struggle and perseverance.
12. “I will appreciate the beauty of small moments.”
13. Positive minds live positive lives. There is always, always something to be thankful for and something to smile about. The happiest people are not those who get everything they want; they are those who, while in pursuit of worthy goals, notice and appreciate the beauty and sweetness of everyday moments.
14. “I will do what I think is right.”
15. What comes easy won’t always last, and what will last won’t always come easy. So do the right things, not the easy things. Whatever comes your way, whatever battle is raging inside you, you always have a choice. In the end, it’s the choices you make that make you who you are. And no matter what, you can always choose to do the right thing.
16. “I will grow from my challenges.”
17. You can be stunned, awakened, and changed by what happens to you, but choose to grow from it, and refuse to be reduced by it. Repeat after me: “I am determined to live a happy life no matter my challenges. I will turn all my tales of fury into tales of glory. I will turn all of my tales of woe into tales of WOW!”
18. “I will realize and use my power.”
19. The most common way people give up their power is by thinking they don’t have any. In a world filled with doubt, you must dare to dream. In a world filled with anger, you must dare to forgive. In a world filled with hate, you must dare to love. In a world filled with distrust, you must dare to believe. And once you do, you will find that power you once thought you lacked.
20. “I will follow the path my heart longs to take.”
21. Life is too short to live with regrets. So love the things that make you smile, let go of the things that make you cry, and believe that everything happens for a reason. Follow the path that your heart longs to take; it’s your time to shine. If you get a chance, take it. If it changes your life, let it. You are far from what you once were, but not yet who you are going to be.
22. The more you know who you are, and what you want, the less you let things upset you.
Paper
1. An indoor navigation system for visually impaired and elderly people based on Radio Frequency Identification (RFID)
(https://sci-hub.tw/https://www.sciencedirect.com/science/article/pii/S0020025514008007)
Abstract
One of the most challenging limitations for the elderly and/or the visually impaired people is the inability of self-navigation in unfamiliar indoor environments. Numerous existing indoor navigation systems have been proposed in order to solve such problems. However, these papers do not adequately examine the effectiveness of the systems in real time trials and are faced with a variety of technical and usability problems. In our paper we present a unique and elegant architecture of an indoor navigation system as an integrated and tested system in real time. This solution enables the localization of the user, as well as the navigation considering scenarios that the user might follow and suggests guidelines for self- navigation. To evaluate the feasibility of the proposed architecture we carried out experimental scenarios to prove that the system proposed is suitable enough to guide elderly people through an unknown built environment.
2. Intelligent face recognition and navigation system using neural learning for smart security in Internet of Things
(https://sci-hub.tw/https://link.springer.com/article/10.1007/s10586-017-1323-4)
Abstract: Most of the advancements are now carried out by interconnecting physical devices with computers; this is what known as Internet of Things (IoT). The major problems facing by blind people fall in the category of navigating through indoor and outdoor environments consisting of various obstacles and recognition of person in front of them. Identification of objects or person only with perceptive and audio information is difficult. An intelligent, portable, less expensive, self-contained navigation and face recognition system is highly demanded for blind people. This helps blind people to navigate with the help of a Smartphone, global positioning system (GPS) and a system equipped with ultrasonic sensors. Face recognition can be done using neural learning techniques with feature extraction and training modules. The images of friends, relatives are stored in the database of user Smartphone. Whenever a person comes in front of the blind user, the application with the help of neural network gives the voice aid to the user. Thus this system can replace the regular imprecise use of guide dogs as well as white sticks to help the navigation and face recognition process for people with impaired vision.In this paper, we have proposed a novel image recognition and navigation system which provides precise and quick messages in the form of audio to visually challenged people so that they can navigate easily. The performance of the proposed method is comparatively analyzed with the help of ROC analysis.
3. Mobile Blind Navigation System Using RFID
(https://sci-hub.tw/https://ieeexplore.ieee.org/abstract/document/7353325/)
Abstract – Blind people need assistance in detecting obstacles, finding locations, and getting directions while moving around to reach their specified destination. Based on this persistent need, we suggest a navigation system to facilitate these requirements. We provided this navigation system to blind students, employees, or guests within King Saud University campus area. The technologies used in our proposed system are: the blind mobile device, RFID tags and Reader, GPS, text to speech, voice Recognition, and WiFi. The system detects the blind location using GPS, if internet connection is available, and uses RFID tags fixed outdoors and indoors on the building in the path, WiFi routers are used indoors to detect the location. The system uses voice recognition and text to speech to communicate with the blind to lead him to his destination and to give him the directions. The results show good performance in obstacles avoidance and in blind guidance.
CONCLUSION : A blind man carrying the RFID Reader and how he will read the nearest tag around Helping blind people to lead an independent life is the main motivation of our research. The system shows good results in detecting blind locations and in co mmunicating with them in a clear and operative way. The next stage in our research is to incorporate vision to solve the problem of obstacles detection both the fixed and the moving obstacles either on ground or the hanged ones in order to make blinds feel safe while moving easily in the university or in any place outside.
