It describes how noise can be controlled at the source through methods like vibration damping, isolation, proper equipment siting and maintenance. Noise can be blocked along the path using barriers, absorbers, insulators and strip curtains. At the receiver, noise control involves enclosing the space using sealed doors/windows and absorptive internal surfaces, as well as using protective equipment like ear plugs.
Solar constant
The document discusses the solar constant, which is the rate at which solar energy arrives at the top of the Earth's atmosphere. It states that the Sun releases approximately 384.6 yotta watts of energy as light and radiation, which appears from Earth as radiation from a black surface at 5,762 degrees Kelvin. The solar constant can be approximated using an equation that takes into account how the distance between the Earth and Sun varies throughout the year. It also mentions spectral distribution of solar intensity and different types of solar radiation including direct, diffuse, and total radiation.
solar still
A solar still is a simple device that uses solar energy to distill and purify water. It has two main types - box and pit stills. Water is evaporated by sunlight and the vapor condenses on the inside surface, then drips down into a collection area. The process removes impurities through evaporation and condensation, producing cleaner water than rainwater. Solar stills have advantages of being low-cost using free solar energy, but also have disadvantages like low production capacity and not killing all bacteria. They can be used to provide clean water for drinking or industrial processes.

1) The document discusses the importance of considering both luminaire efficiency and application efficiency when designing lighting. While saving energy is important, overemphasizing luminaire efficiency alone can result in glare or gloomy spaces.
2) Application efficiency is determined by factors like adequate light levels, uniform illumination, visual comfort, and accurate color rendition. It employs metrics like footcandles, luminaire spacing, and candela measurements.
3) The most appropriate efficiency metric is lighting power density, which establishes an energy budget based on watts per square foot and allows achieving design goals with lower energy use. Considering both luminaire and application efficiency leads to well-lit spaces that satisfy needs and minimize consumption.
GreenStudio - Chapter 4 2 8 Electric Lighthing
Electric lighting systems account for around 19% of global electricity usage and contribute significantly to carbon emissions. To reduce this, the report suggests using more efficient lighting technologies like fluorescents and high-efficiency ballasts. A green electrical lighting system can reduce energy usage for lighting and cooling while improving visual comfort. Key factors that impact lighting strategies include ceiling height, window placement, and luminaire selection and placement. Electric lighting should be addressed during early design phases to maximize energy efficiency.
Illumination Engineering.pdf
This ppt presents you about what is illumination various types of illumination and types of lighting schemes in illumination.there are two main types of lighting one is natural lighting which occurs with the lighting of sun and artificial lighting which occurs due to the artificial sources of light such as bulbs,torches,tubes etc Artificial light sources are other sources of light which developed to compensate for or assist the natural light. It will have different frequencies and wavelengths that determine the light color.Artificial light sources are categorized by the technology used to produce the light. There's dozens of sources, with a few common in household applications and others more suitable for industrial uses. The five most common light sources are as follows:
Incandescent lamp.
Compact fluorescent lamp.
Fluorescent tube.
Discharge lamps.
Light Emitting Diode (LED).
Until recently the most common electric light source was the incandescent lamp. This is still widely used, although its relatively low energy efficiency is leading to its replacement by other more efficient lamps such as the CFL.
The connection to a light fitting is either by screw thread or bayonet.
A large variety of shapes, sizes and power is available, as well as different colour ranges. Typical lamps for household use range from about 40 to 100 W, giving a light output of 420 to 1360lm at the typical lamp efficiency of about 12%.
The compact fluorescent lamp (CFL) was designed as a more efficient replacement for incandescent lamp. It is supplied with the same fixing system (screw or bayonet), and can be used in many light fittings designed for incandescent lamps.
Power ratings of CFLs that can provide approximately the equivalent light output to incandescent lamps are shown in the table below, together with their efficacy ratings.
tube
Fluorescent tubes are the main form of lighting for offices and commercial buildings.
They are a form of gas discharge lamp, and are formed in a long thin glass cylinder with contacts at either end that secure them to the fitting (or luminaire) and provide the electrical connection.
The tube contains mercury vapour at low pressure, and the inner wall of the glass is coated with a phosphor that reacts to ultra-violet radiation. When electricity is passed through the vapour it emits UV radiation that is converted by the phosphor to visible light.
The most efficient fluorescent tubes are the T5. With a smaller diameter (16mm) than earlier tubes, these can achieve a luminous efficacy of up to 104lm/W
Discharge lamps work by striking an electrical arc between two electrodes, causing a filler gas to give off light.
Different metals and filler gasses can be used to provide a range of colour and brightness.
Discharge lamps provide high luminous efficacy combined with long life, resulting in the most economical light source available
Types of gas-discharge lamps:
The gas discharge lamps have three types as follows

Sidelighting is a daylighting strategy that uses apertures located in wall planes to admit ambient daylight, generally from the side, onto a horizontal task plane. Key considerations for sidelighting include the relationship between window height and room depth, views provided by windows, and the need for shading to prevent unwanted solar heat gain and glare. An iterative design process is required to determine the optimal implementation of sidelighting based on daylight factor targets and programmatic needs.

Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic
effect. Lighting includes the use of both artificial light sources like lamps and light fixtures,
as well as natural illumination by capturing daylight .
Ambient (general lighting)
Provides an area with overall illumination. Also known as general lighting, it radiates a comfortable level of brightness without glare
•Task lighting
Helps you perform specific tasks, such as reading, grooming, preparing and cooking food,
•Accent lighting
Adds drama to a room by creating visual interest. As part of an interior design scheme, it is used to draw the eye to houseplants, paintings, sculptures and other prized possessions
Natural light & illumination
Natural light and illumination
This document discusses natural lighting and illumination in buildings. It explains that lighting serves three main purposes: to allow safe movement, task performance, and a pleasant interior. Buildings can be lit naturally through daylight or artificially through electric lamps. Daylight comes from sunlight or skylight.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
