A case study on total Energy Conservation opportunities in a Solar power assi...Ambika Prasanna Dhal
This document summarizes a case study on energy conservation opportunities at a solar power-assisted building. It analyzes the current energy consumption at GIET campus and identifies opportunities to reduce usage. An energy audit was conducted to assess lighting, HVAC, motor, and other loads. Conservation measures like efficient lighting, fans, and motors were implemented. While energy usage increased 10% with a new building from 2012-2014, electricity costs decreased 5.61% due to conservation efforts. The study concludes energy conservation can reduce costs and environmental impacts through efficient technologies and operations.Physics Investigatory Project on Fluid Mechanics

Physics investigatory project
When light passes through a hollow prism containing different media, it undergoes minimum deviation at a particular angle of incidence. This project aims to determine the angle of minimum deviation for a hollow prism containing different media by plotting a graph of the angle of incidence versus the angle of deviation. The relationship between these angles will help identify the angle of minimum deviation.
Physics Investigatory Project Class 12
This document appears to be a student project report on investigating the relationship between input/output voltage and number of turns in the primary and secondary coils of a transformer. It includes sections on introduction, theory, apparatus, procedure, observations, conclusion, and bibliography. The key points are that the output voltage of a transformer depends on the ratio of turns in the secondary coil to the primary coil, and that there are losses between the input and output resulting in the transformer's efficiency being less than 100%.
Sedimentary Rocks
The document discusses different types of igneous and sedimentary rocks. It states that igneous rocks form from cooled magma and their crystal size depends on the cooling rate, with slowly cooled rocks like granite having large crystals and quickly cooled rocks like basalt or pumice having small or no crystals. It describes sedimentary rocks as forming from compacted and cemented sediments, including pieces of other rocks, once-living things like plants and shells, and liquid solutions that leave impressions of fossils.
Metamorphic Rocks
Sandstone forms from cemented sand grains through compaction and cementation. Shale forms from compacted clay and mud sediments. Coal forms from compacted organic material. Limestone forms from cemented calcium carbonate sediments and shells. Sedimentary rocks like sandstone, shale, and limestone can contain fossils.

Earthquakes and Earthquake Waves
The document discusses the theory of plate tectonics. It states that the Earth's surface consists of large moving tectonic plates (E), and that the movement of these plates is driven by convection currents in the mantle (B). It also notes that plate tectonics supports phenomena like sea floor spreading (D) and is evidenced by features like mid-oceanic ridges and deep sea trenches (A). Finally, it indicates that plate tectonics theory provides explanations for earthquakes and mountain building (C).
Mixtures and Separating Mixtures
The document discusses physical and chemical changes, mixtures, and different ways to separate mixtures. It defines a mixture as two or more substances physically combined without a chemical reaction occurring. Mixtures can be either heterogeneous, with components not evenly distributed, or homogeneous, with even distribution making the mixture appear uniform. The document outlines various physical separation methods like straining, magnets, dissolving, evaporation, and exploiting differences in component densities.
Concept Map
Flora is boiling water on the stove. She turns the dial up to high, causing the water to boil vigorously with large, quickly forming bubbles. She then turns the dial down to low, causing the water to boil gently with smaller, slowly forming bubbles. Flora wonders if the boiling temperature changes with the dial settings. The correct answer is C - the boiling temperature remains the same at 100 degrees Celsius regardless of the dial setting.
Heat capacity
Mia and Devon are having a summer party and need to make two sizes of ice. They wonder if the temperature at which water freezes is affected by the size of the ice. Small ice cubes freeze at a lower temperature than large blocks of ice. This is because it takes more energy to freeze a larger volume of water, so large blocks of ice freeze at a slightly higher temperature than small ice cubes.
Density Anomaly
This document discusses buoyancy, density, and why ice floats. It explains that ice is less dense than water due to the formation of hydrogen bonds between water molecules that cause water to expand when it freezes. As a result, the buoyant force on ice is greater than its weight, causing ice to float on water.
Buoyancy
The document compares two solid cubes made of the same material but different sizes - one is large and one is small. It asks which statement about the density of the cubes is true. The correct statement is that the density of the larger cube is the same as the density of the smaller cube, because density is a property of the material and does not change with the size of the object.
Water
Water is a polar covalent compound composed of two hydrogen atoms and one oxygen atom. The electrons in the covalent bonds are shared unequally, with the hydrogen side being partially positive and the oxygen side being partially negative. This gives water molecules a polar nature. Water exhibits both cohesion, the attraction of water molecules to one another, and adhesion, the attraction of water molecules to other substances. Due to its high surface tension, water forms a "skin" on its surface that requires a force to break. When placed in a glass, the water curves up the sides due to surface tension forming a meniscus.
Friction
The document provides an assignment to investigate the impact of fertilizer amounts on plant growth. To properly conduct this investigation, the following factors would need to be controlled: the amount of water given to each plant, keeping track of the fertilizer amounts given to each plant, starting with plants of the same size, and keeping all plants in a similar location. Variables like the amount of fertilizer and location of the plants would need to be manipulated, while the dependent variable of plant height would be measured.
Scientific Method
The document outlines the key steps of the scientific method, which are: 1) identifying a problem or question, 2) researching existing knowledge, 3) forming a hypothesis, 4) testing the hypothesis through experimentation, 5) recording and studying the data, 6) forming a conclusion, and 7) communicating the results. It also defines key terms used in the scientific method, such as hypothesis, variables, control, and constant.
First Day Stuff
This document outlines classroom procedures for an integrated science class taught by Mr. Windsor. It details the daily schedule, which includes 10-15 minutes for warm-up and homework check, 25-30 minutes for lecture and demonstrations, lab/activities that vary in length and format, and 20-25 minutes for quizzes and videos. The document also covers safety procedures for working with electrical and mechanical equipment, as well as chemical hazards, including the Right to Know Law, chemical labeling requirements, and Material Safety Data Sheets.
Concept Map Answers
Great heat and great pressure transforms sedimentary rocks into metamorphic rocks. Complete melting and cooling transforms sedimentary rocks into igneous rocks. The statement that is not true about the rock cycle is that there is only one way for rocks to go through the rock cycle, as any rock type can become any other type of rock through the various processes in the rock cycle.
Bio-geochemical Cycles
The document is a multiple choice quiz about different types of rocks. Question 1 is about sedimentary rocks, which form from compressed or cemented deposits. Question 2 is about metamorphic rocks, which form from great heat and pressure. Question 3 is about igneous rocks, which form from cooled and hardened magma or lava. Question 4 asks about metamorphic rocks again, stating they often form deep in the earth's crust.
Rock Cycle
Metamorphic rocks form deep within the Earth under conditions of great heat and pressure, partially melting existing rocks like igneous or sedimentary stone. Metamorphic rocks can contain fossils from their original parent rock and form in place from the alteration of other types of rock under high temperature and pressure conditions within the Earth's crust. Common examples include marble.
Metamorphic Rocks
The document discusses different types of sedimentary and metamorphic rocks. It states that sandstone forms from cementation, conglomerate forms from compaction, coal forms from organic material, and limestone forms from organic material or liquid solutions. Sedimentary rocks can contain fossils. Metamorphic rocks form from existing rocks undergoing changes from heat and pressure, and examples given are shale transforming to slate and limestone transforming to marble.
Sedimentary Rocks
This document discusses the three main types of rocks: igneous, sedimentary, and metamorphic. It explains that igneous rocks form from cooled magma and have large crystals if they cool slowly, small crystals if they cool fast, and no crystals if they cool extremely fast. Sedimentary rocks form from pieces of other rocks, once-living things, or liquid solutions that harden over time. Metamorphic rocks form from intense heat or pressure that transforms existing rocks.
Igneous Rocks
The document discusses properties of minerals including that minerals are inorganic, have crystal structures, and can be identified by properties like hardness, streak, cleavage, and crystal form. Halite is identified as having cubic crystal formation and displaying fracture when it breaks.
Minerals
Minerals are naturally occurring inorganic solids with a definite chemical composition and orderly atomic arrangement. They typically form crystals with a regular repeating pattern of atoms and break along parallel planes or into specific geometric shapes. Minerals can have a metallic or nonmetallic luster depending on their crystal structure and composition.
Concept Map
1. The document discusses theories of Earth's formation and structure, including the solar nebular theory, continental drift theory, and plate tectonics.
2. It explains that Earth has different layers including the inner and outer core, mantle, and crust. The crust is broken into plates that move due to convection currents in the mantle and gravity.
3. The document also covers earthquakes, describing primary and secondary waves, focal points, and locations being determined through trilateration. Earthquakes commonly occur at plate boundaries like the Ring of Fire. Volcanoes are also discussed in relation to plate tectonics.
Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

From Natural Language to Structured Solr Queries using LLMs
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.
