Transcript: 10/14/2019 Borders Borders 1 In our world there are many different borders that we come across or run into in our life. This is my interpretation on borders around me. Why do borders exist? 2 I think that borders exist because Humans want them to exist. Humans like to have their own space and their own property. Borders are a human made phenomenon that divide where people can and can not go. I believe this because borders can be crossed and are mostly left open to interpretation. For example you do not always know where your exact property line is but instead you have to make an estimate of where that line is. Borders exist in the eyes of humans to keep some group of people in one place and others in another. Borders are what diviedes us but they are also what unites us. Who sets and controls borders? 3 Borders are set by humans, and geography. This is true because there are physical borders set up by people such as walls and fences. One example of this would be the Great Wall of China. There are also geographical borders that are made by continents and landmasses. For example North America and Europe, or the Himalayas. Borders are usually controlled by humans. World governments control borders all the way down to every single human who owns property also controls borders. Do any boundaries make people feel a certain way? Depending on the boundary people feel different ways about them. This is true because some boundaries make people feel safe and secure. Other boundaries make people feel at home because it is their property. Some boundaries also make people feel sad or mad. These boundaries might be places that you want to go to but you are not allowed. For example there may be a very cool place you want to see but it is on private property so you cannot see it. It could also be you want to immigrate to a new country to receive a better life but you are not allowed to. There are also boundaries that might make you feel insecure. For example if you are stuck in a corrupt country or a country in civil war it might make you feel insecure about being there. 4 My Walk and the boundaries I found 5 On my walk I found many different boundaries. I found town boundaries, property boundaries, and street boundaries. There are many different boarders I have found in my life. One of them which is my town. My town separates me from all the other towns in Massachusetts. It's what makes rivaling sports teams. Its what divides where I go to school. It divides where tax dollars go and it divides where I am going to be registered to vote in. Many of these are have effected me in a good way because it has kept where I grow up small and without harm. My own story of borders 6 7 Thanks for watching !
Transcript: A piezoelectric sensor comprises a piezoelectric crystal which is typically mechanically coupled to an object which produces a mechanical movement. In piezoelectric materials, an applied electric field results in elongations or contractions of the material. Block Diagram Expected Outcome The port 0 of the microcontroller is attached a pull-up resistor and interfaced with LCD. The output from the piezoelectric sensor plate is given to the comparator chip(LM 324N), this chip converts it into digital data while it amplifies the data also. The output from the comparator is fed into the microcontroller through port 2.0, where the pinone relay is connected to VCC, pin 2 to ground, pin 3 to the High intensity LED, and the 4th pin to the microcontroller for switching mechanism purpose, whenever the right amount of pressure is applied onto the sensor plate, the comparator receives the signal amplifies and converts it feeds it into the microcontroller as soon as microcontroller gives the indication the contacts in relay touch each other making the LED to glow. The comparator is connected to the battery so whenever the energy is generated that is stored in the battery. The real time clock is interfaced to port2.4, 2.5 for timing so that the counting is done according to real time Circuit Diagram The outcome of it ensures the power saving and efficient power management for street lights without any manual labour and thus can also be used to provide power for home appliances.

Future Scope Thank You..! Working In this project, we are going to implement the design and development of footstep based energy for street lights which consists of Pressure transducer,Relay,Comparator,Battery,Real Time Clock(RTC),Micro controller,Street lights The main aim of this project is to generate the energy through the pressure generated by footsteps. The power supply to the circuit is given through a step down transformer which reduces the 230 Volts AC supply to 12V AC, that is converted into pulsating DC supply through the bridge rectifier used in the circuit. Now the pulsating DC is passed through a filter this filtered output is pure DC, this filtered output is then given to a voltage regulator and a 5 Volts DC supply is obtained and used to power the various components used in the circuit. This 5 Volts DC supply is given to 40th pin of the Microcontroller which is VCC, 9th pin of the Microcontroller for the RESET button, LCD segment, Comparator Chip (LM 324N), Real Time Clock(DS1307).

Transcript: Here is 212 bus stop in LA It is a interesting experience while taking the bus. It would be our first day in LA and my friends and I want to buy the day pass in the bus. The driver found that we did not have the card(something like clipper) after inserting all the fees in the machine. He faced a difficulty that he could not refund us and he did not have extra card on hand. Later, he gave his own card and even the monthly passes to us when we arrived the destination. I was really surprised because it would be never ever happened in Hong Kong and some people(drivers) are so generous that giving their own card to someone they do not know, or even driver may not allow people without paying the bus fees to get on the bus. His behavior reminds me that I should be more generous to others and even helpful. Sure, we had mail back the card to him and wrote some words to appreciate his kindness. Hopefully, he can get our words! Here is at Pier 39 I remember clearly that I went here alone in my first week in SF. It is not common to see people play such a large performance in Hong Kong without others helps to operate all instruments at the same time. I enjoyed his performance around 30 minutes and I really inspired by his passion and braveness to make his dream comes true. He said that he like music and want to share with people here who spend their time to stand here and listen his play. At that time, I was thinking that did I really have the brave to catch my dream and is my dream really big enough to scare myself that I can really give up all my life to work with it? At that stage, I would say I was still searching my dream that I really want to do and it is value that I give up all my hard work to catch it. So, I told myself that I should try more to experiment what I really want but my do the things that told from others (parents). My journey would be continued... Here is the waterfall in Yosemite Valley. I was so excited to go to Yosemite since people said that here is very beautiful and even apple use the views here as its wallpaper template. I was really attracted by the view here, it is really beautiful and I can see the amazing nature. It records the changes from the past to now and it would keep change. And just like us, we would change our attitude towards things and people differently. At that time, my mind sparks up a perspective that I should come here after 30 years with my family or children to see any changes about the rocks or the amount of water falling down. Maybe stand at the same area with the same pose to take a picture. The changes in the nature seems record my growth too and I can share my feelings to my family. Here is Lego land @ California I remember that while I am on the riding of an Uber driver that where we had been in San Diego and I said we had been to the Lego land. He laughed and said it is for kid. I agree with him that it is for kid, but I told him that it is important for us to keep a kid heart or mind to be more happy in life. He knocked his heard and I think he agree with me. And the reason why I put on this picture is while my friend see this snow white, she was keep laughing and said why she is so ugly. I agreed that this princess is not the one we normally saw but I think the message want to share is we should not focus on others appearances and ignore their inner beauties. It is more important for us to understand a person and just determine a person from his/her outlook. Even this snow white does not look like as the one we familiar with, it is true that we all know she has a kind and warm heart. It is a lesson what I learned from this lego puzzle. It would be my travel diary to record my feeling to a specific object or event. Record my perspectives, after few years, when I look back, It would be an amazing moment to see the growth of self. My born city The place where I familiar with, I learn many knowledge and approaches to face my happiness and sadness. When I look back my 20 years life, it seems that I just stay inside this box and stay as usual as not understanding other cultures and I would say it just like I have only one thinking side or mind set but not a multiple to develop myself. So, I make a big decision that leaving my family, friends and all things that I used to and join the exchange program. And, It is time to put my step forward to see other communities and develop my self, the inner part of me! Growth My FootStep Hong Kong San Diego Yosemite National Park Los Angeles San Francisco

Transcript: Grayson Watson 1. Longfellow uses an amazing structure to express his thoughts in this poem. The speaker effectively depicts the image of these saints entering the door, alongside his "beloved." Her abstract, yet understood presence empowers the speaker to some extent, but they all must leave once again, since they are no longer a part of this earth. When the hours of Day are numbered, And the voices of the Night Wake the better soul, that slumbered, To a holy, calm delight; Ere the evening lamps are lighted, And, like phantoms grim and tall, Shadows from the fitful firelight Dance upon the parlor wall; Then the forms of the departed Enter at the open door; The beloved, the true-hearted, Come to visit me once more; He, the young and strong, who cherished Noble longings for the strife, By the roadside fell and perished, Weary with the march of life! They, the holy ones and weakly, Who the cross of suffering bore, Folded their pale hands so meekly, Spake with us on earth no more! 3. 3rd Person 2. The Speaker of this poem is an unknown narrator. And with them the Being Beauteous, Who unto my youth was given, More than all things else to love me, And is now a saint in heaven. With a slow and noiseless footstep Comes that messenger divine, Takes the vacant chair beside me, Lays her gentle hand in mine. And she sits and gazes at me With those deep and tender eyes, Like the stars, so still and saint-like, Looking downward from the skies. Poetic Analysis "Footstep of Angels" "Footsteps of Angels" Uttered not, yet comprehended, Is the spirit's voiceless prayer, Soft rebukes, in blessings ended, Breathing from her lips of air. Oh, though oft depressed and lonely, All my fears are laid aside, If I but remember only Such as these have lived and died! The title symbolizes that the dead never truly leave us and we follow in their footsteps.

Transcript: 1.0 INTRODUCTION The piezoelectric effect is understood as the linear electromechanical interaction between the mechanical and the electrical state in crystalline materials with no inversion symmetry. The piezoelectric effect is a reversible process in that materials exhibiting the direct piezoelectric effect (the internal generation of electrical charge resulting from an applied mechanical force) also exhibit the reverse piezoelectric effect (the internal generation of a mechanical strain resulting from an applied electrical field) . The figure shows how some of the charge becomes separated in a piezoelectric material when stressed. The ability to produce electric power from mechanical reaction (force) and then it change to electric charges. It is impossible to replace the existing electricity generation, but at least to vary and reduce the dependency on the conventional electricity generation. Design concept used in this project is to use piezoelectric place at the walking area named as “foot step power generation system”. When a human walking, jumping or dancing on the surface which contain the piezoelectric, it then will produce sufficient force for energy generation process. Therefore, the continued pressure will provide sufficient resources to be used to produce the electricity required. Power generation using foot step can be used for agricultural, home applications , street lighting. Foot step power generation also can be used in emergency power failure situations. Other than that , it can also be used at: a) college b) hospitals c) shopping complex d) many other buldings Piezoelectricity has arose as a way to harvest energy. The array of piezoelectric crystals are laid under the pavements. The voltage produced can be utilized to charge batteries. It is to be noted that scientist at the Hull University worked on converting motion in to electrical energy. Japan has installed piezoelectric tiles in Tokyo’s busiest stations. This method is to save usage of electrical energy and use the energy from our daily activities which can be used to generate electricity. CONTENTS DEE 5081 PROJECT 1 1.1 PROBLEM STATEMENT 2.0 BLOCK DIAGRAM 3.0 CIRCUIT DIAGRAM Whenever force is applied on piezoelectric crystals that force is converted to electrical energy and it is used to drive DC and ACloads. At that minute, voltage is stored in the lead acid battery, the battery is connected to the inverter. The inverter is used to connect the 12 volt D.C to the 230 volt A.C. This 230 volt A.C voltage is used to activate the loads. We are using conventional battery charging unit also for giving supply to the circuit. 1.2 OBJECTIVES 1.0 Introduction 1.1 Problem Statement 1.2 Objectives 1.3 Scope 2.0 Block diagram 3.0 Circuit Diagram 4.0 Flowchart 5.0 Components and Costing 6.0 Working Principle 7.0 Application 8.0 Conclusion 9.0 Refference 6.0 WORKING PRINCIPLES SUPERVISOR : ENCIK FAIRUZ ABADI BIN KHALID 7.0 APPLICATION 1.3 SCOPE Day by day, the population of the country increased and the requirement of the power is also increased. At the same time the wastage of energy also increased in many ways. So reforming this energy back to usable form is the major solution. As technology is developed and the use of gadgets, electronic devices also increased. Power generation using conservative methods becoming deficient. There is a necessity arises for a different power generation method. At the same time the energy is wasted due to human locomotion and many ways. To overcome this problem, the energy wastage can be converted to usable form using the piezoelectric sensor. So by using this energy saving method, that is the footstep power generation system we are generating power.
