Engine cooling system
The cooling system uses five basic parts - water jackets, water pump, thermostat, radiator, and fan - to regulate the engine's temperature. The water pump circulates coolant through the water jackets in the engine and then into the radiator, where the coolant is cooled by the airflow of the fan before returning to the engine. The thermostat controls the flow of coolant to maintain optimal engine temperature. The cooling system is needed to prevent overheating and damage to engine parts from high temperatures during operation.

Vortex tube _steam_jet_refrigeration
Vortex tube refrigeration uses compressed air and has no moving parts. Air is passed through a nozzle into a chamber where it spins creating hot and cold streams. The cold air exits through a diaphragm hole while the hot air exits through a valve. Steam jet refrigeration uses steam expanded through nozzles to lower pressure and boil water below 100C for refrigeration. High pressure steam enters nozzles and flash chamber, lowering pressure and evaporating water to decrease temperature before chilled water is circulated for use. Both systems have advantages of simplicity and flexibility but limited capacity and efficiency.

Analysing stability in water-in-diesel fuel emulsion
The diesel engine exhaust gas consists of many hazardous components which need to be reduced. Incorporation of water in fuel restricts the emission of such toxic gases and helps to reduce pollution. The aim of this research work is to develop water-in-diesel fuel emulsion having maximum stability. Initially, the most suitable surfactant/blend of surfactants has been investigated which gives maximum stability to W/D emulsion. It is found that blend of SPAN 80/TWEEN 80 gives effective result. The W/D emulsion was prepared by high speed mixing homogenizer and adding a small amount of water into diesel containing blend of SPAN 80/TWEEN 80. The results show that 10% W/D emulsion having 5% surfactant concentration gives most desirable emulsion stability. Beyond 10% water concentration, the properties of W/D emulsion get lowered.

Rack and pinion
The document describes rack and pinion gears. A rack and pinion system uses two gears - a pinion gear which is circular, and a rack gear which is flat. The pinion gear engages with the teeth on the rack gear to convert rotational motion into linear motion or vice versa. Rack and pinion systems are commonly used in steering systems in cars, where the rotation of the steering wheel is converted to linear motion that turns the wheels. The key components of a rack and pinion steering system are the pinion, rack, inner ball joints, tie rods and rubber bellows.
Fuel water emulsions
Fuel water emulsion technology can be used in IC engines to reduce emissions. An emulsion is a mixture of two immiscible liquids, like oil and water, mixed using a surfactant. Surfactants lower the interfacial tension between liquids to allow an emulsion. Diesel-water emulsions use surfactants with a hydrophilic-lipophilic balance of 7-11. Tests show diesel-water emulsions with 7.5% water reduce nitrogen oxide emissions by 30-50% without compromising performance. The water improves atomization and lowers flame temperature during combustion.

Differential in automobile
An automobile differential couples the drive shaft to the rear driving wheels. It allows the outer wheel to rotate faster than the inner wheel during a turn by splitting torque equally between the wheels. A differential consists of one input and two outputs for the two driving wheels. It allows the wheels to rotate at different speeds to accommodate turns while keeping the average rotational input equal to the drive shaft. Differentials are commonly used in automobiles but also have non-automotive applications like performing analog arithmetic or controlling gun aim. There are different types of differentials like epicyclic, spur gear, and bevel gear differentials.

Presentation about transformer and its types
- A transformer is a static device that changes electrical power at one voltage level into electrical power at another voltage level through magnetic induction. It does not change the frequency.
- There are two main types of transformers: step-up transformers, which increase voltage, and step-down transformers, which decrease voltage. This is achieved by varying the number of turns in the primary and secondary coils.
- Transformers work on the principle of mutual induction. A changing magnetic field induced by alternating current in the primary coil induces a voltage in the secondary coil.

Cooling system
The cooling system serves to remove excess heat from the engine through combustion and friction. It works to quickly bring the engine up to optimal operating temperature and maintain it there. There are two main types - air cooling, which radiates heat through fins to the atmosphere, and liquid/water cooling, which circulates coolant through water jackets and a radiator. Water cooling cools more uniformly and improves fuel efficiency but requires more components and depends on the water supply. The main components of a water cooling system are the radiator, water jackets, water pump, and thermostat.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Low power architecture of logic gates using adiabatic techniques
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
