This document is a technical seminar report submitted by Rohit Singh for the degree of Bachelor of Technology in Electronics and Telecommunication Engineering. It provides an introduction and overview of Ferroelectric Liquid Crystal Displays (FLCDs), including their operating principle, molecular orientation control, device structure, gray scale addressing, properties and uses. FLCDs utilize a chiral smectic C liquid crystal phase with spontaneous polarization, allowing bistable states that provide memory effect and fast response time.
Nikola Tesla was a Serbian-American inventor known for his contributions to modern alternating current electricity. He attended university in Austria and Croatia to study engineering. In 1884, Tesla immigrated to New York with little money but a letter of recommendation. He worked for Thomas Edison solving engineering problems, but Edison refused to pay Tesla the promised $50,000 for redesigning his inefficient motor. Tesla went on to make breakthroughs in electric motor and power distribution technology using alternating current.

This document provides an overview of environmental chemistry. It begins by defining environmental chemistry and describing the key environmental segments of the biosphere, atmosphere, hydrosphere, and lithosphere. It then discusses environmental quality standards, indicators of pollution including dissolved oxygen, chemical oxygen demand, biochemical oxygen demand, and total dissolved solids. The document outlines the scope of environmental chemistry and notes the need for public awareness of environmental issues.
The document is a scrapbook about Nikola Tesla created by Erin Rome. It provides biographical details about Tesla's life and career as an inventor, including that he was born in 1856, invented the Tesla coil in 1891, developed commercial alternating current power, and made many contributions to electricity and wireless energy transmission before dying in 1943. The scrapbook also shares a diary entry by Tesla from 1861, quotes from Tesla, and information about museums dedicated to his work.
This document provides an overview of environmental chemistry. It discusses the study of chemical and biochemical phenomena that occur in the environment and how they can have harmful effects. Specific topics covered include atmospheric, water, and soil pollution. Atmospheric pollution results from the addition of undesirable materials to the air from natural or human sources. Water pollution stems from domestic and industrial waste. Soil pollution is caused by chemicals from waste dumping, pesticides, urbanization, and mining. The document also discusses waste management methods like reduction, reuse, and recycling. It introduces green chemistry which aims to reduce pollution by designing safer chemicals and processes.
This document discusses ferroelectric liquid crystal displays (FLCDs), which use the interactions between the spontaneous polarization of ferroelectric liquid crystals and electric fields. FLCDs provide faster response times below 1 ms compared to traditional LCDs. Key advantages of FLCDs include very wide viewing angles, high resolution with small pixel sizes, and prevention of cross-talk. FLCDs operate based on the bistable states of ferroelectric liquid crystal molecules when an electric field is applied to align their spontaneous polarization. Challenges facing FLCDs include controlling alignment defects and cell spacing, operating over a wide temperature range, and improving response times and grayscale.
Green chemistry: Production of electricity from AmmoniaArosek Padhi
This slide shows a new method to produce electricity from ammonia. This technique use replenish-able methods and resources to produce electricity thus giving better outputs of energy
The document discusses metamaterials and their applications. It begins with defining metamaterials as artificially engineered materials with properties not found in nature. It then discusses techniques for achieving negative permeability and permittivity values, challenges in optical metamaterials, and applications including 3D metamaterials, slow light, cloaking, chiral metamaterials, and superlensing. The talk is divided into sections on different metamaterial topics that will be covered.
Nikola Tesla and Thomas Edison were both renowned inventors in the late 19th/early 20th century. Tesla pioneered developments in alternating current and made breakthroughs in wireless energy and X-rays. However, he struggled financially and had eccentric personality traits that made his ideas difficult to understand. In contrast, Edison successfully commercialized inventions like the light bulb and founded research labs, but his focus was more on business than discovery. Their competition highlighted tensions between scientific progress and profit motives, with Tesla's unrecognized visions ultimately leading to his decline.
Environmental pollution occurs when materials or energy are discharged into the environment in a way that causes harm. It can have both direct and indirect negative impacts on ecosystems. Tropospheric pollution exists in the air in both gaseous and particulate forms from sources like vehicle emissions, industrial pollution, and natural events. Common gaseous pollutants are oxides of sulfur, nitrogen, and carbon which can cause respiratory issues. Particulate matter includes dust, smoke, and liquid droplets. Global warming is caused by the greenhouse effect trapping heat from carbon dioxide and methane in the atmosphere. Acid rain occurs when rainwater falls and reacts with air pollutants like sulfur and nitrogen oxides, lowering its pH and damaging
Nikola Tesla was a Serbian inventor born in 1856 who made many contributions to the development of modern electrical infrastructure. Some of his most important inventions included the Tesla coil, AC induction motor, and wireless energy transfer. He had a rivalry with Thomas Edison over whose electrical system - DC or AC - would become the standard. Despite some of his revolutionary ideas not being fully realized until after his death, Tesla is now recognized for how many of his technological visions helped enable the modern world.

2. Charakterystyka ryzyka
Ryzyko jest obecne we wszystkich dziedzinach działalności człowieka, wówczas,
kiedy ludzie nie są w stanie kontrolować, albo dokładnie
przewidzieć przyszłości. Ryzyko jest więc elementem, który towarzyszy
w większym lub mniejszym stopniu prowadzeniu każdej
działalności gospodarczej. Ryzyko utożsamiane jest z możliwością
występowania skutków negatywnych, jak i pozytywnych, a więc
możliwością wystąpienia stanu innego od zaplanowanego.
Rodzaje ryzyka:
I. Ryzyko społeczne.
II. Ryzyko przyrodnicze-szczególny rodzaj tego typu ryzyka to ryzyko
pogodowe, które dzielimy na:
A) ryzyko o charakterze katastroficznym,
B) ryzyko o charakterze niekatastroficznym.
3. Wpływ ryzyka pogodowego na poszczególne
branże
• Szacunki Międzynarodowego Stowarzyszenia Zarządzania Ryzykiem
Pogodowym (WRMA) wskazują, że około 60% wszystkich firm jest
bezpośrednio lub pośrednio uzależniona od warunków pogodowych.
• Nie wszystkie sektory są wrażliwe w 100%, a niektóre
w ogóle nie są narażone na ryzyko pogodowe. Jednak łączna wartość
poszczególnych sekcji narażonych na ryzyko w 2000 roku to blisko 40%
wartości PKB.
Do sektorów najbardziej narażonych na ryzyko pogodowe należy:
energetyka,
rolnictwo,
przemysł spożywczy i browarniczy,
budownictwo,
przemysł rozrywkowy i turystyczny,
transport,
miejskie służby porządkowe.
4. Wpływ ryzyka pogodowego na poszczególne
branże
• Elektrociepłownie
ryzyko zmiany poziomu sprzedaży produktu (energii cieplnej).
• Rolnictwo:
ryzyko ceny,
ryzyko dochodu,
ryzyko zdarzeń pogodowych.
• Budownictwo:
ryzyko dochodu,
ryzyko zdarzeń pogodowych.
5. Zabezpieczenie przed ryzykiem pogodowym
• Instrumenty mające na celu ochronę poszczególnych branż gospodarki można
podzielić na dwie grupy. Pierwszą obejmującą ubezpieczenia oraz drugą oferującą
instrumenty pochodne.
• Instrumentami, które są najlepszym zabezpieczeniem przed ryzykiem pogodowym o
charakterze niekatastroficznym są pochodne instrumenty pogodowe (derywaty
pogodowe).
• Derywaty pogodowe są to dwustronne kontrakty terminowe, które są rozliczane na
podstawie warunków atmosferycznych, takich jak indeksy temperatury, opady czy
prędkość wiatru. Jest to umowa pomiędzy dwoma stronami, która określa warunki
płatności pomiędzy zawierającymi transakcję, w zależności od zajścia określonych
zdarzeń pogodowych w okresie trwania kontraktu. Klasyczny pochodny instrument
pogodowy można opisać za pomocą kontrakt typu forward, future, opcji lub swap.
• Ważny jest czas trwania kontraktu, określenie stacji pogodowej, która dostarcza dane
meteorologiczne oraz indeks pogodowy stanowiący podstawę transakcji. Ponadto
należy określić ceny wykonania transakcji oraz (w przypadku opcji) wartość premii za
kontrakt.
6. Instrumenty zarządzania ryzykiem pogodowym
Ubezpieczenia:
rozwiązania długoterminowe,
wysokie ryzyko i niskie prawdopodobieństwo,
jednorazowa kwota odszkodowania.
Derywaty pogodowe:
rozwiązania krótkoterminowe,
niskie ryzyko i wysokie prawdopodobieństwo,
wypłata proporcjonalna do wielkości zdarzenia.
7. Derywaty pogodowe
SPOSÓB DZIAŁANIA:
• identyfikacja i pomiar narażenia danego podmiotu na ryzyko o charakterze
niekatastroficznym;
• konstrukcja indeksu;
• ustalenie wartości jednego punktu z powstałego indeksu;
• wybór instrumentu finansowego.
ZALETY:
• prosta konstrukcja,
• skuteczne narzędzie zabezpieczające dochody podmiotów gospodarczych,
• atrakcyjny element dywersyfikacji portfela.
WADY:
• problem z wyceną,

9. OZE
Rynek OZE jest bardzo wrażliwy na nietypowe wahania pogody, każde
odchylenie od przeciętnej może pociągnąć za sobą
duże straty finansowe. Niestety, mimo dużego potencjału, derywaty
pogodowe nie znalazły dotąd zastosowania dla OZE, jest to
nowe rozwiązanie, które wymaga opracowania oraz jak
najszybszego wprowadzenia.
