A Compact Remote Switching With Efficient Monitoring For AC Plants
Remote monitoring has been implemented in many areas. This paper
introduces its specific application to air-conditioning plant control and
monitoring using PIC Microcontroller. Remote monitoring and intelligent
maintenance is one of the most important criteria for maximizing production
and process plant availability. Initially switching and monitoring were done
through manually and the control switches and level monitoring unit were
placed at separate places. Due to this, we cannot monitor all units at a time. In
our proposed system, remote switching and monitoring is done in the control
room itself. Majority of industries use distributed control system for high
reliability, improve response time, improved operator interface to plant,
improved accessibility of plant data.
Vertical air conditioning system
Vertical air conditioning systems use vertical vents on the floor to direct cool air in areas that lack walls or ceilings. These omnidirectional vents can be turned in any direction. A package air conditioning system keeps all components like the condenser, compressor, and blower in a single unit. It draws in fresh air, cools it through condenser coils, and pushes the air through vents via the blower. At a cinema mall in Vadodara, vertical vents were placed at the entrance on the ground floor, getting air from the basement through 2-meter high vents above human height with blowers above. Package AC and ducting were also used to pass cool air to the theater space.

Compressors system Designing 919825024651
Compressors are mechanical devices that compress gases. There are two main types - dynamic and positive displacement. Dynamic compressors include centrifugal and axial compressors, which use rotating impellers to add velocity and pressure. Positive displacement compressors trap a fixed amount of air and force it into the discharge pipe; types include rotary and reciprocating compressors. Reciprocating compressors use pistons driven by a crankshaft to compress gases. Selection depends on operating conditions like flow rate and pressure ratio. Applications include HVAC, refrigeration, and industrial processes.

BASIC OF HVAC.pptx
The document provides an overview of basic HVAC systems. It defines HVAC as heating, ventilation, and air conditioning. It describes the major components of HVAC systems including compressors, condensers, expansion valves, and evaporators. It explains that HVAC systems work using a vapor compression refrigeration cycle consisting of these four components. The document also discusses different types of HVAC systems like split, central, and packaged AC systems. It provides diagrams of typical system designs and components.
Air conditioning system
The document discusses the components and process of an air conditioning system. It describes the key elements as the compressor, condenser, expansion valve, and evaporator. The refrigerant gas flows in a cycle between these components, being compressed into a hot gas in the compressor, condensed into a liquid in the condenser, expanded in the expansion valve, and evaporated to absorb heat in the evaporator. There are different types of air conditioning systems including room, package, and central systems.
Centralized ac system
Centralized air conditioning systems serve multiple spaces from one central location using chilled water distribution and extensive ductwork. They have higher efficiencies than decentralized systems due to shared cooling capacity. Common centralized systems use central chillers and distribute chilled water to air handling units or fan coils. Decentralized systems have independent cooling units in each space and offer more flexibility but lower efficiency. Common applications of centralized systems include large buildings like hotels, malls, and airports.
Air Conditioning system and types
The document discusses different types of air conditioning systems. It begins with introductions to air conditioning principles and the cooling cycle. It then describes four main types of air conditioning systems: window units, split systems, centralized systems, and packaged units. Window units have all components in one casing, while split systems separate indoor and outdoor components. Centralized systems serve whole homes through ductwork. Packaged units can cool entire buildings and contain heating systems.
Mechanical Equipment
Central air conditioning systems have several key components:
1) A central plant room contains the chiller, compressor, condenser, and other equipment that cools water which is circulated throughout the building.
2) Air handling unit rooms include air handling units that blow cooled air into ductwork leading to individual rooms.
3) Air conditioned rooms receive cooled supply air through ceiling diffusers and return warm air to the air handling units through floor diffusers.
4) A cooling tower cools the water used by the central chiller and condenser before it is recirculated.

Pvd final 17 etmm10 mahfooz
Physical vapor deposition (PVD) involves vaporizing a material source and condensing it as a thin film on a substrate. Thermal evaporation and sputtering are two common PVD methods. Thermal evaporation heats a source material to vaporize it, while sputtering uses a plasma to bombard a target material and eject atoms to deposit on the substrate. PVD requires vacuum conditions to allow vapor transport without collisions between vapor particles and gases. Common applications of PVD thin films include electronics, optics, tool coatings, and decorative coatings.

mahfooz_piezoelectricity
Piezoelectricity is the ability of certain materials to generate an electric charge in response to applied mechanical stress. Pierre Curie discovered this effect in 1880 in quartz crystals. When pressure is applied to piezoelectric materials, the ions in the crystal unit cells are displaced, causing an electric polarization. Conversely, an electric field will cause the crystals to mechanically deform. Common piezoelectric materials include quartz and barium titanate. Piezoelectricity is used in applications such as smart sensors, medical imaging, energy harvesting, and more. Lead-based piezoelectrics are widely used but lead-free materials are being developed due to environmental concerns.

The mechanism involves the more noble metal acting as the cathode and the less noble metal corroding as the anode due to potential differences between the metals. Factors like material properties, surface area ratios, and electrolyte composition affect the corrosion rate. Measures to reduce galvanic corrosion include choosing metals close in the galvanic series, insulating dissimilar metals, and using cathodic protection with a sacrificial anode. Applications of galvan
mahfooz_deformation in cryst_al
Slip and twinning are two important deformation mechanisms in crystals. Slip involves the sliding of atomic planes over one another along crystallographic planes called slip planes, and occurs when the critical resolved shear stress is exceeded. It is controlled by dislocations. Twinning involves mirror-image reflections on either side of a twinning plane, where successive atomic planes are displaced by increasing amounts. Twinning accommodates deformation by changing the crystal orientation and is important when slip systems are limited. The key differences between slip and twinning are that slip is a line defect controlled by dislocations while twinning is a grain boundary surface defect.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

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.
