Question: Why is MPPT necessary?
Context: Maximum power point tracking (MPPT)[1][2] or sometimes just power point tracking (PPT),[3][4] is a technique used with variable power sources to maximize energy extraction as conditions vary. The technique is most commonly used with photovoltaic (PV) solar systems, but can also be used with wind turbines, optical power transmission and thermophotovoltaics.

PV solar systems have varying relationships to inverter systems, external grids, battery banks, and other electrical loads.[5] The central problem addressed by MPPT is that the efficiency of power transfer from the solar cell depends on the amount of available sunlight, shading, solar panel temperature and the load's electrical characteristics. As these conditions vary, the load characteristic (impedance) that gives the highest power transfer changes. The system is optimized when the load characteristic changes to keep power transfer at highest efficiency. This optimal load characteristic is called the maximum power point (MPP). MPPT is the process of adjusting the load characteristic as the conditions change. Circuits can be designed to present optimal loads to the photovoltaic cells and then convert the voltage, current, or frequency to suit other devices or systems.

Solar cells' non-linear relationship between temperature and total resistance can be analyzed based on the Current-voltage (I-V) curve and the power-voltage (P-V) curves.[6][7] MPPT samples cell output and applies the proper resistance (load) to obtain maximum power.[8] MPPT devices are typically integrated into an electric power converter system that provides voltage or current conversion, filtering, and regulation for driving various loads, including power grids, batteries, or motors. Solar inverters convert DC power to AC power and may incorporate MPPT.

The power at the MPP (Pmpp) is the product of the MPP voltage (Vmpp) and MPP current (Impp).

In general, the P-V curve of a partially shaded solar array can have multiple peaks, and some algorithms can get stuck in a local maximum rather than the global maximum of the curve.[9]
Answer: The efficiency of transferring the power from the photovoltaic (PV) solar systems depends on many factors which change frequently. MPPT system purpose is to continuously adjust the parameters under which the system work to achieve the most efficient transfer of power from the solar system to the load.

It opened in 1979 with anchor stores Belk-Beery (now Belk), JCPenney, and Sears. A later expansion added a new wing and Dillard's store to the center after Westfield Group purchased the mall.[1] The mall is located on Oleander Drive (U.S. 76) and Independence Blvd east of downtown Wilmington. The mall has a food court and no longer features a carousel.
Answer: Independence mall is located in Wilmington, North Carolina.
Question: Extract out the various endorsements Twice has done and separate them with a comma
Context: Endorsements:

Even before the official debut of Twice, the nine members had signed contracts as exclusive models for school uniform brand Skoolooks, alongside J. Y. Park. By December 2015, Twice had signed ten CF contracts, totaling earnings of KRW1.8 billion.[272][273] By February 2017, they had one of the fastest growths in the advertising industry as the group's rate charged for endorsement hit 200 million won for 6 months and 300 million won for a year.[274]

Twice is one of the celebrity endorsers of Lotte Duty Free. They also collaborated with shoe company Spris and created their own shoe brand called "Twice by Spris".[275][276] In early 2017, Twice was selected by beverage maker Donga Otsuka to promote the company's flagship sports drink Pocari Sweat on its 30th anniversary. They became the first idol group to model for the brand. Pocari Sweat recorded 100 billion won sales for the first half of the year, a 10% increase over 2016's sales.[277][278]

As of 2017, Twice has represented about 30 different brands including cosmetics, clothing, online and mobile games, food and beverages, credit cards, and more.[279] Twice's first TV commercial in Japan for Ymobile was aired nationwide starting February 2, 2018, incorporating a pop arrangement of "Y.M.C.A." and Twice's signature "TT pose".[280][281] In 2019, Twice was selected as South Korean ambassador of Estée Lauder.[282] The group also became "Global Benchsetters" for Philippine clothing brand Bench.[283][284] In March 2021, Kyungnam Pharmaceuticals announced that it had selected Twice as the representatives for its flagship vitamin brand Lemona.[285] Later that year, Nintendo Korea featured Twice playing the Nintendo Switch game Mitopia in a video.[286] In August 2021, the group was chosen to perform for Shopee Philippines's 9.9 Super Shopping Day TV special that was held on September 9.[287] On October 16, 2021, Scarlett Whitening, an Indonesian beauty brand known for its skin whitening products, introduced Twice as their brand ambassadors. The endorsement was, however, criticized by fans, calling JYP Entertainment to withdraw the deal as it would be "unethical" for Twice to endorse a brand with skin whitening products, "knowing that they have fans with darker skin complexions".[288][289]

Question: What are the most common causes of avalanches, in descending order of likelihood (where most likely is first)?
Context: Most avalanches occur spontaneously during storms under increased load due to snowfall and/or erosion. The second largest cause of natural avalanches is metamorphic changes in the snowpack such as melting due to solar radiation. Other natural causes include rain, earthquakes, rockfall and icefall. Artificial triggers of avalanches include skiers, snowmobiles, and controlled explosive work. Contrary to popular belief, avalanches are not triggered by loud sound; the pressure from sound is orders of magnitude too small to trigger an avalanche.[3]

Avalanche initiation can start at a point with only a small amount of snow moving initially; this is typical of wet snow avalanches or avalanches in dry unconsolidated snow. However, if the snow has sintered into a stiff slab overlying a weak layer then fractures can propagate very rapidly, so that a large volume of snow, that may be thousands of cubic metres, can start moving almost simultaneously.

A snowpack will fail when the load exceeds the strength. The load is straightforward; it is the weight of the snow. However, the strength of the snowpack is much more difficult to determine and is extremely heterogeneous. It varies in detail with properties of the snow grains, size, density, morphology, temperature, water content; and the properties of the bonds between the grains.[4] These properties may all metamorphose in time according to the local humidity, water vapour flux, temperature and heat flux. The top of the snowpack is also extensively influenced by incoming radiation and the local air flow. One of the aims of avalanche research is to develop and validate computer models that can describe the evolution of the seasonal snowpack over time.[5] A complicating factor is the complex interaction of terrain and weather, which causes significant spatial and temporal variability of the depths, crystal forms, and layering of the seasonal snowpack.
Answer: The most likely causes of avalanches, in order of likelihood, are:
- Increased snow loads during storms
- Erosion in the snowpack caused by storms
- Metamorphic changes in the snowpack such as melting due to weather or rain
- Earthquakes that trigger shifting in the snowpack
- Falling objects, such as rockfall and snowfall, can trigger avalanches
- Human triggers, such as skiers, snowmobiles, and controlled explosives.
Question: Summarize the parliamentary 2023 elections results in Andorra
Context: On the evening of 2 April, the Andorran government announced the results: the ruling coalition of Democrats for Andorra (DA) and Committed Citizens (CC) won the elections with 16 seats, gaining 3 more seats and the absolute majority of Consell General's seats. It was followed by the new Concord party, which won 5 seats. The third place was won by the progressive coalition formed by the Social Democratic Party (PS) and Social Democracy and Progress (SDP), which lost 4 seats, remaining with 3. In last positions, the new parties Andorra Forward, which won 3 seats, and Action for Andorra (Accío), which won one. At a press conference, Xavier Espot, accompanied by the Minister of Finance and acting government spokesman Cesar Marquina, proclaimed these results.[44] Liberals of Andorra was left without parliamentary representation, losing the 4 seats it had.[45]

The turnout was 66.95%, 1.3% less than that recorded in the 2019 elections, despite being higher than in previous years.[44][46] Early voting rose to 30%, the highest figure ever recorded.[46]
Answer: Xavier Espot, Cesar Marquina, and the Minister of Finance confirmed April 2nd, 2023 that the Democrats of Andorra and Committed Citizens parties won with an absolute majority (16 seats total, adding 3 new seats). The turn out was very similar to 2019, with just 1.3% less voting (66.95% in total). This may have been due to a record turn out in early voting, which was higher than ever recorded at 30%.

Answer: Peloton became a public company via an initial public offering on September 26, 2019.
Question: List the states which are part of the western ghat
Context: The Western Ghats extend from the Satpura Range in the north, stretching from Gujarat to Tamil Nadu.[17] It traverses south through the states of Maharashtra, Goa, Karnataka and Kerala. Major gaps in the range are the Goa Gap, between the Maharashtra and Karnataka sections, and the Palghat Gap on the Tamil Nadu and Kerala border between the Nilgiri Mountains and the Anaimalai Hills. The mountains intercept the rain-bearing westerly monsoon winds, and are consequently an area of high rainfall, particularly on their western side. The dense forests also contribute to the precipitation of the area by acting as a substrate for condensation of moist rising orographic winds from the sea, and releasing much of the moisture back into the air via transpiration, allowing it to later condense and fall again as rain.[citation needed]

The northern portion of the narrow coastal plain between the Western Ghats and the Arabian Sea is known as the Konkan, the central portion is called Kanara and the southern portion is called Malabar. The foothill region east of the Ghats in Maharashtra is known as Desh, while the eastern foothills of the central Karnataka state is known as Malenadu.[18] The range is known as Sahyadri in Maharashtra and Karnataka. The Western Ghats meet the Eastern Ghats at the Nilgiri mountains in northwestern Tamil Nadu. The Nilgiris connect the Biligiriranga Hills in southeastern Karnataka with the Shevaroys and Tirumala hills. South of the Palghat Gap are the Anamala Hills, located in western Tamil Nadu and Kerala with smaller ranges further south, including the Cardamom Hills, then Aryankavu pass, and Aralvaimozhi pass near Kanyakumari. The range is known as Sahyan or Sahian in Kerala. In the southern part of the range is Anamudi (2,695 metres (8,842 ft)), the highest peak in the Western Ghats. Ooty is called the Queen of the Western Ghats.
Answer: Western ghats stretches from Gujurat to Tamil Nadu states of India. It traverses south through the states of Maharashtra, Goa, Karnataka and Kerala. The northern portion of western ghats is called Konkan, the central is called Kanara and the southern portion is called Malabar.

Question: Based on this paragraph on Japanese bullet trains, how many cars do the longest trains have?
Context: Trains are up to sixteen cars long. With each car measuring 25 m (82 ft) in length, the longest trains are 400 m (1⁄4 mile) end to end. Stations are similarly long to accommodate these trains. Some of Japan's high-speed maglev trains are considered Shinkansen,[34] while other slower maglev trains (such as the Linimo maglev train line serving local community near the city of Nagoya in Aichi, Japan) are intended as alternatives to conventional urban rapid transit systems.
https://en.wikipedia.org/wiki/Shinkansen
Answer: Based on this paragraph, the longest Japanese bullets trains have 16 cars, which is determined by dividing the length of the longes trains (400m) by the length of each car (25m).
Question: Which trophy was Frost able to keep and why?
Context: Frost became interested in sport at a young age and was an all-round athlete. He won medals for running and swimming and was a prominent member of the Winchester Harriers sports club. He particularly excelled as a cyclist, entering competitive events at an early age and holding several amateur cycling records. In 1898, Frost won, within the space of a fortnight, Britain's two leading cycle racing trophies, the Bath Road 100 and the Cawardine Challenge Cup, as well as the national championship. By the time he retired he had won every important amateur cycling trophy in the nation.[1][2][3]

He is particularly remembered for winning the Carwardine Challenge Cup, a 100-mile race held annually at the Herne Hill race track. This huge cup was donated by the vice-president of the Anerley Bicycle Club in 1895 and was made from 650 ounces of silver, with ornamentation of solid gold. The tradition at the time was that if someone won a trophy three times they could keep it. Frost, riding for the Bath Road club in Hayes, first won it in 1896, repeated the victory in 1898 and was victorious for the third time in 1900. The cup is occasionally exhibited in Winchester.[1][2][4]
Answer: Frost was a prominent cyclist. In the late 1800s and early 1900s when he was active he was able to win the Carwardine Cup trophy and keep it. The tradition at the time was that if one could win a trophy 3 times, one could keep the trophy. Frost won this trophy in 1896, 1898 and 1900.

Question: Extract a list of calendars mentioned and display the names in valid, well-formatted JSON
Context: The course of the sun and the moon are the most salient regularly recurring natural events useful for timekeeping, and in pre-modern societies around the world lunation and the year were most commonly used as time units. Nevertheless, the Roman calendar contained remnants of a very ancient pre-Etruscan 10-month solar year.[2]

The first recorded physical calendars, dependent on the development of writing in the Ancient Near East, are the Bronze Age Egyptian and Sumerian calendars.[3]

During the Vedic period India developed a sophisticated timekeeping methodology and calendars for Vedic rituals.[4] According to Yukio Ohashi, the Vedanga calendar in ancient India was based on astronomical studies during the Vedic Period and was not derived from other cultures.[5]

A large number of calendar systems in the Ancient Near East were based on the Babylonian calendar dating from the Iron Age, among them the calendar system of the Persian Empire, which in turn gave rise to the Zoroastrian calendar and the Hebrew calendar.[citation needed]
Answer: Roman calendar, Bronze Age Egyptian calendar, Sumerian calendar, Vedanga calendar, Babylonian calendar, Zoroastrian calendar, Hebrew calendar

Context: A geoboard is a mathematical manipulative used to explore basic concepts in plane geometry such as perimeter, area and the characteristics of triangles and other polygons. It consists of a physical board with a certain number of nails half driven in, around which are wrapped geo bands that are made of rubber. Normal rubber bands can also be used. Geoboards were invented and popularized in the 1950s by Egyptian mathematician Caleb Gattegno (1911-1988).[1]
Answer: A geoboard is made of a physical board, some nails, and geo bands that could be rubber bands.
Question: From the passage list down the location of Visa data centers. List the results in semi colon separated format.
Context: Visa Inc. (/ˈviːzə, ˈviːsə/; stylized as VISA) is an American multinational financial services corporation headquartered in San Francisco, California.[1][4] It facilitates electronic funds transfers throughout the world, most commonly through Visa-branded credit cards, debit cards and prepaid cards.[5] Visa is one of the world's most valuable companies.

Visa does not issue cards, extend credit or set rates and fees for consumers; rather, Visa provides financial institutions with Visa-branded payment products that they then use to offer credit, debit, prepaid and cash access programs to their customers. In 2015, the Nilson Report, a publication that tracks the credit card industry, found that Visa's global network (known as VisaNet) processed 100 billion transactions during 2014 with a total volume of US$6.8 trillion.[6]

Visa was founded in 1958 by Bank of America (BofA) as the BankAmericard credit card program.[7] In response to competitor Master Charge (now Mastercard), BofA began to license the BankAmericard program to other financial institutions in 1966.[8] By 1970, BofA gave up direct control of the BankAmericard program, forming a cooperative with the other various BankAmericard issuer banks to take over its management. It was then renamed Visa in 1976.[9]

Nearly all Visa transactions worldwide are processed through the company's directly operated VisaNet at one of four secure data centers, located in Ashburn, Virginia; Highlands Ranch, Colorado; London, England; and Singapore.[10] These facilities are heavily secured against natural disasters, crime, and terrorism; can operate independently of each other and from external utilities if necessary; and can handle up to 30,000 simultaneous transactions and up to 100 billion computations every second.[6][11][12]

Visa is the world's second-largest card payment organization (debit and credit cards combined), after being surpassed by China UnionPay in 2015, based on annual value of card payments transacted and number of issued cards.[13] However, because UnionPay's size is based primarily on the size of its domestic market in China, Visa is still considered the dominant bankcard company in the rest of the world, where it commands a 50% market share of total card payments.
Answer: Ashburn, Virginia; Highlands Ranch, Colorado; London, England; Singapore
