Literature Review Of Vast Rectenna - 1028 Words

7 CHAPTER 2 AMBIENT RF ENERGY HARVESTING COMPONENTS AND LITERATURE REVIEW 2.1 RECTENNA ITS COMPONENT A rectenna is a rectifying antenna, a sort of antenna that is used to convert microwave energy or radio frequency energy into direct current signal that can power low sensor devices. They are modelled as a part of wireless power transmission systems that transmit power through radio waves or electromagnetic waves. A basic rectenna, comprises of a microstrip patch antenna with a RF diode. It is nonlinear rectifying element (for example Schottky diode, Zener diode, IMPATT diode.... etc.). The diode rectifies the alternating current or bidirectional current induced in the patch antenna by the RF waves, to generate DC or unidirectional†¦show more content†¦2.1.2 RECTIFIER A rectifier is an electrical device that converts bi-directional current or alternating current (AC), to unidirectional current or direct current (DC). This process is called rectification. Rectifiers have many uses including high-voltage direct current power transmission systems, in DC power supplies and in detection of radio signals. There are two types of rectifier, the half wave rectifier and the full wave rectifier. In our case, given the need of matching as the less number of components, half wave rectifier has been used. 2.1.2.1 Half Wave Rectifier The half wave rectifier rectifies only half cycle of the AC input waveform. The half wave rectifier consists of a step down transformer, a diode connected to the transformer and a load resistance connected to the cathode side of the diode. 2.1.2.2 Full Wave Rectifier The circuit of full wave rectifier uses two rectifier elements and the transformer with secondary center tapped. One for the positive half cycle and other for the negative half cycle. The output DC in full wave rectifier is twice that of half wave rectifier and the frequency is twice that of the supply frequency. 2.1.3 IMPEDANCE MATCHING Impedance matching is one of the most eminent part of the RF circuits. It is utilized for the purpose of transferring maximum

Personal Narrative- Destruction of Nature If you ever get a chance to visit Chaco Canyon National Monument in New Mexico, you should take the time to just stand in the desert and listen. The silence in this place is physical; you can feel it surround you. This is a silence with depth and layers that are unbroken even by the wind, which moves through emptiness and speaks only in occasional sighs through the canyons. The air itself is very clear—the lack of humidity gives the cliffs and buttes sharp lines, and the colors of the earth, though muted, stand in stark relief to the blueness of the sky.

I realize this consciousness is atypical of many of my compatriots. However, the roots of my compulsive musings are not wholly random because I was subjected to much similar thinking from an early age. Having grown up in a region where civilization and development were slow in coming, and where trees outnumber cornstalks and coal mines corn silos, we had ample opportunity to reflect on man’s relationship to nature. My parents are two well-educated, biologically trained individuals with an almost obsessive need to be outdoors. They met, so the story goes, in a graduate school class when my mother asked my father for his pocketknife to scrape moss from a tree trunk. It was love amongst the bryophytes. They spent several years trekking all over the U.S. on vacations to national forests and monuments and deserts and mountains, and my arrival on the scene did not cease their wanderings. Though I did restrict the locale. There are numerous pictures of one of my parents standing on some wooded ridge with the peak of my red hat sticking up over their shoulder. Once I was old enough to scramble along the trails by my own power, my father began taking me to work with him. In those days, he was a state biologist, and by the time I started kindergarten, I had been all over the state hiking, trapping, caving, camping, and generally running as a feral child.

Boss Review Mike Royko free essay sample

Mike Royko captured the life of a truly amazing man, Mayor Richard Daily. Royko in the book, Boss, follows an diffident beginnings on the South Side of Chicago in the Bridgeport neighborhood to Daley’s rise as a powerful politician. Being born in 1902 and rasied by Michael and Lillian Daley. Difficult by humble house which some accredited later to Richards difficulty in communicating. Daley did not have siblings to communicate with early in life. Even after public life he still had a difficult time voicing his opinions. Daley was a shy, introverted child who was not a standout in academics or in sports Sometime in his early years, many schoolmates found leadership and qualities and an intangible charisma that both proved to be crucial later in his career. It was not common not see many children those day to not attend college.. For his high school education, Richards parents sent him to a school run by the Christian Brothers, where he learned office skills and discipline and order. We will write a custom essay sample on Boss Review Mike Royko or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page After graduating, he wound up with his first city job. He would stay on the governments payrolls for the next forty-eight years, twenty of those years as Mayor of Chicago. While one would think the title Boss would refer to his mayoral career, it more appropriately was a reference to his long-term control of the powerful Chicago political machine. As head of the machine, he knew everything about everyone in the Democratic Party. He had control of the money and the thousands of patronage jobs that he handed out like candy in return for bringing in the vote. The machine presided over the ward bosses, precinct captains and the voters. The Boss controlled the Machine with a selfish fervor. He made the unusual move of maintaining chairmanship of the Illinois Democratic Party (The Machine) even after he became mayor. He was well aware that the Machine held more power that the position of mayor. At one time, he was considered the most powerful man in Illinois and the second most powerful man in the nation, just behind President John F. Kennedy. The story of Richard J. Daley reveals an undeniable parallel between the man and the city. Daley excelled in the rough politics in the notoriously corrupt Chicago. Would he have been as successful in another city or state? Perhaps not, but Daley was the perfect match for Chicago. He was a man whose less than pure ethics was understood by Chicagoans. Perhaps he wouldnt have been as understood and accepted in another environment. Although he dealt with known corruption, Daley operated within a strange dichotomy, a parallel universe. While he was not known to take a dime, he operated with others who did. As boss, he would just tell them not to get caught. He was a devout Catholic who attended mass every morning yet he allowed the poor to suffer for years in inadequate housing and under brutal police abuse. Richard J. Daley was a rough-tough character, Chicago rough-tough. His grammar and speaking skills did not bring the praise of teachersfar from it. He was hot-tempered, simple, devious and powerful. Many in the country may not have understood him, but Chicagoans did. Daley reflected Chicago. Daley was a product of his neighborhood. He reflected its valuesloyalty to family, neighbors, old buddies, the corner grocer. Good neighbors cut their grass and dont have their TVs too loud. He was a pious manever faithful to his church, mom and apple pie, disturbed by public displays of immorality. But if somebody in City Hall had a chance to make some money on the sly, Daley wasnt into lecturing except perhaps for a simple one: Dont get caught. If Daley sometimes abused his power, it did not offend Chicago. The many immigrants into the city fully understood a man in authority wielding power, a power they had long ago learned to bow to. Not only was Daley not offensive, he became a father figure to many in the city. There was an odd security that he offered. Although Daley has passed away, he has left an indelible legacy for the city that long will survive him. Daley was like Chicagonothing was better than a good, political brawl. The city he loved will remember and embrace that legacy for years to come.

View on Privacy Essay free essay sample

Enemy of the State and Ben Franklin View on Privacy course: Date: Monday November 5, 2012 Privacy Is a core human right, which allows the human to preserve his/her dignity, independence. And freedom, therefore, Is an essential liberty ()_ Benjamin Franklin said in 1 759; They that can give up essential liberty to purchase a little temporary safety, deserve neither liberty nor safety, and is correct to have said this. Enemy of the State demonstrates the validity of the statement by making three different examples of what can happen if one gives up even a small amount of liberty.The movie demonstrates how giving up liberty in exchange of temporary security can affect the life of an Innocent man, how It can lead to corruption, and how it can even backfire on the conformists of this bill. In the long run, there are no winners when it comes to the public giving up their privacy and trust someone to not misuse the power. We will write a custom essay sample on View on Privacy Essay or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page In Enemy of the State, Invasion of privacy ruined the lives of innocent people. One of the people affected by this Invasion was Rachel Banks. Ms. Banks is murdered by the National Security Agency () to try and frame Robert Dean, even Hough both are innocent.Another innocent person who has his life destroyed was Daniel , a wildlife researcher (Midi). Mr. . Also loses his life all because one of his hidden cameras, which was designed to monitor geese, recorded a murder done by the NASA. The third innocent person who has their life turned into chaos is Robert Dean. Although Robert Dean doesnt lose his life like the other two, he still goes through a lot because he has the videotape with the murder, and he doesnt connected to a murder, and the murderers are invading their privacy to try to prevent the public from finding out about the murder.Giving already-powerful people more power over the public and their privacy is guaranteed to lead to corruption. This is demonstrated in Enemy of the State by Thomas Reynolds. Mr. . Reynolds invades the private life of Phil to try to convince him to support a bill that would let the government invade the privacy of innocent people even easier. When his persuasion fails, Mr.. Reynolds resolves to murder. Because Thomas Reynolds is so powerful, it is easy for him to spy on Mr.. Dean even though there is only a slight suspicion that Mr..Dean is involved. Mr.. Reynolds uses his power to spy on Dean by tapping his house and clothes, phones, and house, canceling his credit cards, and installing surveillance equipment in his house without his permission (Midi). Reynolds also has Rachel Banks killed Just to try to frame Dean, and this shows corruption because he feels that he has a lot of power, and thus isnt afraid that he will get in trouble for conspiring to murder an innocent person. Because Reynolds has a lot of power, he is corrupted by it and also grows careless with his actions.Although the watchers of the peace feel like they can do anything with all of the power that is available to them, they still need to be careful. In the movie, the USA spy on innocent people with the technology that they have developed specifically for that purpose. Near the end of the movie, Brills uses their own equipment to spy on them, and then blackmails them. Also, the USA are so used to watching others that they forget that others can also watch them, so they are careless (In). When they are murdering , they dont check the surroundings for cameras that could be recording them, and that becomes their downfall.Lastly, the NASA feel completely secure because of all of their power, so they are reckless to walk into a dark restaurant with a mafia family and dont feel threatened until they are being shot at. Total power can make even the most disciplined men relaxed and feeling almighty, which is clearly demonstrated in Enemy of the State. The suffering of innocent people, corruption of large authorities, and the arrogance of powerful organizations are three big effects on a society that has given up privacy for some protection. These three effects were powerfully demonstrated n the movie called Enemy of the State.

A Christians Experience In A Mosque Religion Essay Example

A Christians Experience In A Mosque Religion Essay Example A Christians Experience In A Mosque Religion Essay A Christians Experience In A Mosque Religion Essay I am a Christian by personal religion, genetic sciences and through circumstance of being raised in the church. I have been a Christian so long that any other faith to me is of small concern to me personally. But, I do non state this to be average because I have many friends of different faiths, beliefs and races. Whatever they believe in is all right with me and frailty versa. I decided to travel to a mosque with my best friend since 4th class since she is a Muslim. I learned a batch more than I originally thought and this is my journey. Humama and I have been best friends since 4th class. My household and hers are close despite one being Christian and the other Muslim. To each other we are people, friends, and faith does non specify our relationship. I asked Humama to come with me to the mosque business district on King Street because I would experience more comfy being with person who knew what was traveling on. We decided to travel on a Friday, which is their holy twenty-four hours. Before go forthing her house in Goose Creek, we performed ritual called a Wudu. It is rinsing of organic structure parts of import to executing formal supplications, called Salah. She said that there is a station at the mosque for it, or they use a sink for it but it would be easier to make it before we left place. She gave me a bluish outfit to have on with a fiting head covering to cover everything from our carpuss to our mortise joints for modestness and regard. On the thrust business district, bundled up in a beautiful outfit wholly out of my normal signifier of dressing, I wondered how I would be greeted and how I would be changed by this. I have walked and drove past the mosque on King Street many times. After populating business district for about a twelvemonth, you would hold to be blind non to detect it. It sits at that place on the corner of King and Romney street, quiet and non architecturally designed like the mosques I have seen in images. It is simplistic in its design for its intent. We parked and walked to the mosque and I noticed people of different races come ining the mosque which surprised me. There were Blacks, White persons, and many people of Middle Eastern descent. There were immature people, old people and all seemed unified in their beliefs of Allah. We entered the mosque and entered a speedy supplication to bless the mosque. The supplication had non started yet, so Humama introduced me to other Muslims in the hallway. My anxiousness was easing slightly talking to others that did non look to mind I was at that place, despite being a Christian. Before come ining the existent mosque, Humama and I took off our places to demo another signifier of regard. Humama and I sat confronting Mecca, after talking for a few proceedingss to the others, she said we could offer other speedy supplications while waiting for the discourse to get down. I realized for the first clip that the work forces and adult females were separated in the mosque. The work forces were in the forepart and the adult females in the dorsum, though we could still see everything. I noticed that there were two rows of chairs and I saw that the disableds or work forces of importance sat at that place. I sat beside Humama thought, this is sort of unjust holding to sit all the manner in back and non among the work forces. In my church you sit anyplace, but I pulled the idea back, to non judge but take part in her religion. To acquire my head off it, I thought to myself that I truly enjoyed non holding my places on since I am slightly Bohemian. Humama informed me we were waiting for the Imam, the sermonizer and leader of the mosque, to come out and preach which is called the Pre-Prayer. She informed that the Imam would normally come out and give a discourse on whatever he wished to or state a spiritual narrative. He would subsequently in the discourse connect the significance of it to his discourse. I became a small impatient waiting for the Imam to come out, but she reassured me that he would be out shortly. After five more proceedingss he walked out and world eventually set in that I was wholly out of my deepness. The Imam, whose existent name is Mohamed Melhem did non look like a sermonizer to me. He seemed like a regular adult male yet easy to speak to. He began the discourse by welcoming everyone to the mosque and praising Allah. He was easy to listen to and to understand. He gave a discourse on functioning Allah and fasting. That by fasting you gain a closer relationship with Allah. Allah is at that place for us and there is merely one. Prayer should be consistent ( they pray five times per twenty-four hours ) and that the Quran is at that place to steer us. He spoke of being a Muslim in the universe, that all facets of being a Muslim should be retained one time go forthing the mosque. As a Muslim, your moralss and how you stick to them in the universe shows how Allah is working through you. I noticed that everyone seemed in awe and took in every word he said. They seemed wholly devoted to listening to the Imam speak about this, because by looking at them you could state some found themselves once more by being among equals like themselves. After completing the discourse, the Adhan or Azan, did a call to prayer. Everyone listened and moved frontward face down listening to the Azan pray. After the supplication was finished, some people continued to pray and others got up to socialise. The mosque offered nutrient to us to raise money for the mosque. The nutrient was similar to what I had eaten earlier at Humama s house and it was delightful. I do non retrieve the names of the nutrient, but it did non affair at the clip. Everyone socialized for about an hr and a half and some continued to talk about Allah, others about school and work. Some people were coming in late holding merely got off work to come in at the right clip to pray. Leaving the mosque, I felt a small different. The peace of praying with others who get along despite your race. The sacredness of go forthing the universe outside and happening yourself once more when come ining the mosque. Confronting Mecca and everyone praying in one way and at one clip. They all believe the same manner and it shows why they have such a strong community. No 1 is seeking to draw off and do their ain thing. It made me experience nearer to my ain God, and that it makes life easier cognizing that basically we all have the same belief in one God, despite the different ways we worship. I gained a closer relationship with my best friend and with my God and that truly changed me.

Homeland Security for the Port of Baltimore Essay

Homeland Security for the Port of Baltimore - Essay Example With so much at stake, it is no doubt crucial to consider all possible threats a place like Port Baltimore may be vulnerable to and be prepared with measures to ensure the safety of the city, the people involved, the property and the security of the whole country. Ports are crucial for both, the security of a country and its trade and economy, as they serve as terminals with access across its boundaries. This opens possibilities for infiltration of illegal activities and products along with the usual trade. Thus ports pose a great threat of certain hazards or sources of possible disaster to the city and the country if left improvised. Of the many threats that enable U.S agencies to take effective measures for the protection of the country’s resources and vulnerable assets, the threat of terrorism has the greatest power, especially in the post 9/11 era. The possibilities of terrorist attacks via shipping ports are innumerable. With only six percent of the nine million container s entering the U.S, (Medalia 2) and fourteen percent of the 140,000 containers at Baltimore being examined for explosives, (Davis and GormanSun), it is evident that these portals to the United States are pretty much available to terrorists wanting to strike. It would be fairly easy to hide explosives in the eight to nine feet high and twenty to forty feet long containers that are used to carry the cargo transported between ports. (Medalia 2) Apart from being easy and susceptible targets, they are also fairly attractive in terms of results for such terrorist groups as well. With inflammable material that can cause a minor explosion to spread over miles, even a ten to twenty kiloton bomb could cause a loss of more than $1.2 trillion from direct and indirect costs resulting from the damage of property and disruption of trade activity. (Medalia 2). The destruction could extend to a radius of one or two miles, thus affecting the city the port is in, resulting in a comprehensive disaster. (Medalia 3). Another equally hazardous threat to the U.S port is Drug smuggling, which was the number one priority before September 11, 2001. The failure in the prohibition of drugs infiltrating the country may result in indirect facilitation of terrorist activities and a larger impact on the society by fuelling crime and disease. (Loy 156). According to statistics provided by Interagency Assessment of Cocaine Movement, most of the transportation of illegal drugs is carried out through the sea. (Loy 157) The third effective threat to U.S coasts and ports is the possibility of damage and injury caused by the mishandling of hazardous materials that have the ability to contaminate and destroy not only cargo and property, but marine life and the environment. All this can inadvertently affect the economy by interference in trade and recreation activities around the water front as well as health of the citizens of the port city. Provided that the forces threatening the security of port t oday are much better equipped than they were a decade ago, it is necessary to maintain the efficiency of security systems in the context of developing technology and update methodologies to keep up with the unpredictable and surreptitious approach of the possible enemies of the state. (Pike) Coast guard and customs and Border protection are federal agencies with the strongest presence in seaports. After 9/11 coast guard has created the largest port
