Type casting in java
Type casting in javaFarooq Baloch Type casting involves assigning a value of one data type to a variable of another type. There are two types of casting: widening (implicit) and narrowing (explicit). Widening casting converts data to a broader type without needing explicit casting, like converting an int to a long. Narrowing casting converts to a narrower data type and requires explicit casting, such as converting a double to a long.
Typecasting in c
Typecasting in cTushar Shende Typecasting in C allows changing the data type of a variable, regardless of its original definition. When a variable is typecast to a new type, the compiler treats it as the new type. In the example, dividing two integers results in 0, but casting them to floats first results in the actual quotient of 0.625. Typecasting can be implicit, letting smaller types automatically cast to larger ones in expressions, or explicit using cast operators like (int) or (float). Explicit casts have higher priority and force a specific conversion.
Ifi7184.DT lesson 2
Ifi7184.DT lesson 2Sónia This document provides an overview and outline of a lesson on variables and types in Java. The key points covered include:
- Variables are names for locations in memory that hold values. Primitive data types include numerical, character, and boolean values. Complex objects are instances of classes.
- Variables are declared with a data type, name, and optional initial value. Primitive values can be output and converted between types through casting or automatic promotion.
- Expressions combine operators and operands to compute results. Operators have precedence that determines the order of evaluation. Assignment operators store the result of an expression into a variable.
- The lesson covers primitive data types, variables, expressions, output, conversion, and creating objects
data types in C-Sharp (C#)
data types in C-Sharp (C#)Abid Kohistani This document discusses data types in C#. It explains that variables must be assigned a data type that specifies their size and values. The common data types covered are integer, floating point, boolean, character, and string. Integer types like int and long store whole numbers, while floating point types like float and double store fractional numbers. Boolean stores true/false values, char stores a single character, and string stores text. It also discusses type casting and conversion, where implicit casting automatically converts smaller types to larger ones, while explicit casting requires manually placing the type in parentheses. User input is covered, noting that ReadLine returns a string, so numerical input requires conversion to the correct type like Convert.ToInt32.

Templates exception handling
Templates exception handlingsanya6900 C++ templates allow functions and classes to operate on multiple types of data. Templates define placeholders that are substituted by template arguments. This allows defining functions and classes once that can work with different data types. Function templates define a single function that generates multiple versions based on the template arguments. Class templates generate distinct classes from a single definition. Exceptions represent errors and are thrown using throw statements. Exception handlers use try-catch blocks to catch exceptions and provide error handling.

It discusses key OOP concepts like objects, classes, encapsulation, inheritance and polymorphism. It also covers procedural programming in C++ and compares it with OOP. Examples are provided to demonstrate creating classes, objects, functions, constructors and destructors. The document contains information on basic C++ programming concepts needed to understand and implement OOP principles in C++ programs.
Data Type Conversion in C++
Data Type Conversion in C++Danial Mirza The document discusses data type conversion in C++. It explains that data type conversion can be either implicit (automatic) or explicit (user-defined). Implicit conversion occurs automatically during operations with mixed data types, changing operands to the larger type. Explicit conversion requires a cast operator to manually change a value's type. Four main cast operators are discussed: dynamic_cast, static_cast, reinterpret_cast, and const_cast.

Type casting in c programming
Type casting in c programmingRumman Ansari Type casting is converting a variable from one data type to another. It is done explicitly using a cast operator like (type_name). It is best to cast to a higher data type to avoid data loss as casting to a lower type may truncate the value. There are two types of casting in C - implicit casting which happens automatically during assignment, and explicit casting which requires a cast operator. Implicit casting is done when assigning a value to a compatible type while explicit casting is needed when types are incompatible.

Functions make code reusable and easier to understand by separating code into modular units. A function has a name, list of arguments it takes, and code that is executed when the function is called. Functions can communicate between each other via parameters passed by value or by reference. Parameters passed by value are copied, so changes inside the function don't affect the original variable, while parameters passed by reference allow the function to modify the original variable. Functions can also call themselves recursively.

Process Parameter Optimization for Minimizing Springback in Cold Drawing Proc...
Process Parameter Optimization for Minimizing Springback in Cold Drawing Proc...Journal of Soft Computing in Civil Engineering In tube drawing process, a tube is pulled out through a die and a plug to reduce its diameter and thickness as per the requirement. Dimensional accuracy of cold drawn tubes plays a vital role in the further quality of end products and controlling rejection in manufacturing processes of these end products. Springback phenomenon is the elastic strain recovery after removal of forming loads, causes geometrical inaccuracies in drawn tubes. Further, this leads to difficulty in achieving close dimensional tolerances. In the present work springback of EN 8 D tube material is studied for various cold drawing parameters. The process parameters in this work include die semi-angle, land width and drawing speed. The experimentation is done using Taguchi’s L36 orthogonal array, and then optimization is done in data analysis software Minitab 17. The results of ANOVA shows that 15 degrees die semi-angle,5 mm land width and 6 m/min drawing speed yields least springback. Furthermore, optimization algorithms named Particle Swarm Optimization (PSO), Simulated Annealing (SA) and Genetic Algorithm (GA) are applied which shows that 15 degrees die semi-angle, 10 mm land width and 8 m/min drawing speed results in minimal springback with almost 10.5 % improvement. Finally, the results of experimentation are validated with Finite Element Analysis technique using ANSYS.

Development of MLR, ANN and ANFIS Models for Estimation of PCUs at Different ...Journal of Soft Computing in Civil Engineering Passenger car unit (PCU) of a vehicle type depends on vehicular characteristics, stream characteristics, roadway characteristics, environmental factors, climate conditions and control conditions. Keeping in view various factors affecting PCU, a model was developed taking a volume to capacity ratio and percentage share of particular vehicle type as independent parameters. A microscopic traffic simulation model VISSIM has been used in present study for generating traffic flow data which some time very difficult to obtain from field survey. A comparison study was carried out with the purpose of verifying when the adaptive neuro-fuzzy inference system (ANFIS), artificial neural network (ANN) and multiple linear regression (MLR) models are appropriate for prediction of PCUs of different vehicle types. From the results observed that ANFIS model estimates were closer to the corresponding simulated PCU values compared to MLR and ANN models. It is concluded that the ANFIS model showed greater potential in predicting PCUs from v/c ratio and proportional share for all type of vehicles whereas MLR and ANN models did not perform well.

Introduction to FLUID MECHANICS & KINEMATICS
Introduction to FLUID MECHANICS & KINEMATICSnarayanaswamygdas Fluid mechanics is the branch of physics concerned with the mechanics of fluids (liquids, gases, and plasmas) and the forces on them. Originally applied to water (hydromechanics), it found applications in a wide range of disciplines, including mechanical, aerospace, civil, chemical, and biomedical engineering, as well as geophysics, oceanography, meteorology, astrophysics, and biology.
It can be divided into fluid statics, the study of various fluids at rest, and fluid dynamics.
Fluid statics, also known as hydrostatics, is the study of fluids at rest, specifically when there's no relative motion between fluid particles. It focuses on the conditions under which fluids are in stable equilibrium and doesn't involve fluid motion.
Fluid kinematics is the branch of fluid mechanics that focuses on describing and analyzing the motion of fluids, such as liquids and gases, without considering the forces that cause the motion. It deals with the geometrical and temporal aspects of fluid flow, including velocity and acceleration. Fluid dynamics, on the other hand, considers the forces acting on the fluid.
Fluid dynamics is the study of the effect of forces on fluid motion. It is a branch of continuum mechanics, a subject which models matter without using the information that it is made out of atoms; that is, it models matter from a macroscopic viewpoint rather than from microscopic.
Fluid mechanics, especially fluid dynamics, is an active field of research, typically mathematically complex. Many problems are partly or wholly unsolved and are best addressed by numerical methods, typically using computers. A modern discipline, called computational fluid dynamics (CFD), is devoted to this approach. Particle image velocimetry, an experimental method for visualizing and analyzing fluid flow, also takes advantage of the highly visual nature of fluid flow.
Fundamentally, every fluid mechanical system is assumed to obey the basic laws :
Conservation of mass
Conservation of energy
Conservation of momentum
The continuum assumption
For example, the assumption that mass is conserved means that for any fixed control volume (for example, a spherical volume)—enclosed by a control surface—the rate of change of the mass contained in that volume is equal to the rate at which mass is passing through the surface from outside to inside, minus the rate at which mass is passing from inside to outside. This can be expressed as an equation in integral form over the control volume.
The continuum assumption is an idealization of continuum mechanics under which fluids can be treated as continuous, even though, on a microscopic scale, they are composed of molecules. Under the continuum assumption, macroscopic (observed/measurable) properties such as density, pressure, temperature, and bulk velocity are taken to be well-defined at "infinitesimal" volume elements—small in comparison to the characteristic length scale of the system, but large in comparison to molecular length scale

"Boiler Feed Pump (BFP): Working, Applications, Advantages, and Limitations E...
"Boiler Feed Pump (BFP): Working, Applications, Advantages, and Limitations E...Infopitaara A Boiler Feed Pump (BFP) is a critical component in thermal power plants. It supplies high-pressure water (feedwater) to the boiler, ensuring continuous steam generation.
⚙️ How a Boiler Feed Pump Works
Water Collection:
Feedwater is collected from the deaerator or feedwater tank.
Pressurization:
The pump increases water pressure using multiple impellers/stages in centrifugal types.
Discharge to Boiler:
Pressurized water is then supplied to the boiler drum or economizer section, depending on design.
🌀 Types of Boiler Feed Pumps
Centrifugal Pumps (most common):
Multistage for higher pressure.
Used in large thermal power stations.
Positive Displacement Pumps (less common):
For smaller or specific applications.
Precise flow control but less efficient for large volumes.
🛠️ Key Operations and Controls
Recirculation Line: Protects the pump from overheating at low flow.
Throttle Valve: Regulates flow based on boiler demand.
Control System: Often automated via DCS/PLC for variable load conditions.
Sealing & Cooling Systems: Prevent leakage and maintain pump health.
⚠️ Common BFP Issues
Cavitation due to low NPSH (Net Positive Suction Head).
Seal or bearing failure.
Overheating from improper flow or recirculation.

Type Casting in java programming language.pptx
- 2. What is type casting? Assigning a value of one type to a variable of another type is known as Type Casting. Example Int x=10; byte y=(byte)x;
- 3. Type of Casting There are Two types of type casting. Implicit Casting(Widening/By Compiler) Explicit Casting(Narrowing/By Programmer)
- 4. Implicit Casting(Widening/by compiler) In Implicit casting we converted the data or value into broad data Example byte short int long float double widening
- 5. Example of Implicit(widening) public class Test { Public static void main(String args[]) { int i=100; long l=I; //no explicit type casting required float f=I; //no explicit type casting required System.out.println(“Int Value “+i); System.out.println(“Long Value “+l); System.out.println(“Int Value “+f); } } OUTPUT Int Value 100 Long Value 100 Float Value 100.0
- 6. Explicit Casting(Narrowing/by Programmer) In Explicit casting we converted the data or value into Narrow data Example byte short int long float double narrowing
- 7. Example of Explicit(narrowing) public class Test { public static void main(String args[]) { double d=100.04; long l=(long)d; //explicit type casting required Int i=(int)I; //explicit type casting required System.out.println(“Double Value “+d); System.out.println(“Long Value “+l); System.out.println(“Int Value “+i); } } OUTPUT Double Value 100.04 Long Value 100 Int Value 100
