Abstract:

A vibrating single spring mass system has several applications. One of the applications is to determine the Harmonic motion of the vibrating bodies under damp or undamped conditions. These can furthermore have the utility in creating stable constructions. Specifically, in this lab report, three set of experiments are undertaken – study the vibrations of the spring & mass system and damper under undamped , damped and free fall condition. The three experiments’ procedures are explained in this lab report. The expected plots for the first experiment, that is, determining the natural Continue reading...

Back titration of Calcium Carbonate with Sodium Hydroxide.

Introduction
Here the amount of Calcium Carbonate is asked and because it is an insoluble salt "back titration" is used. Titration is a method which it's another name is volumetric method, in this method a reactant is used to bring a reaction to endpoint. In this method, one sample (unknown) value is determined by a standard (known) value.
But "back titration" is needed because here Calcium Carbonate is an insoluble salt and it's not possible to calculate its amount by direct titration.
In this experiment first calcium carbonate was reacted with an excess known hydrochloric acid and the unreacted Continue reading...

The Equation group is one of the most advanced threat actor that has been used in multiple computer network exploitation (CNE) operations since 2001. It is a highly developed cyber attack group that involves using of multiple malware platforms.
This treat actor is called the Equation group because it is using trough their malware and operations a specific type of the encryption algorithm RC5 and obfuscation strategies. The recent modules besides cryptographic features use RC4, RC6, and AES.

The Equation group is using a multiple malware platforms such as: EquationDrug, DoubleFantasy, Equestre, TripleFantasy, GrayFish, Fanny, EquationLaser.

EquationDrug is a very complicated attack platform that maintains a module plagin system and used on victims of the Equation group. Continue reading...

As opposed to traditional mathematical models and equations, the equality free model theory is aimed at examining mathematical formulas that do not have equalities based on algebra logic. This can also be referred to as first order logic without equality. In the language, there are two structures. We can interpret these structures in an alternative manner in first order logic. When this structure is used, the term normal model is used to refer to two individuals that exist. If these two items A,* and B* are present and they do not satisfy the equation A,* ≅B* , the term normal Continue reading...

ABSTRACT

The significance of cardiovascular fitness to people’s health has been well recognized. For Cardiovascular fitness, the components of activity incorporated are not merely for endurance training and muscular development. VO2 max or maximal oxygen uptake determines an athlete's ability to conduct sustained exercise and is associated with aerobic endurance. Measuring VO2 max perfectly necessitates a maximum exertion usually on a bicycle or treadmill executed under strict rules in a sports lab. This paper seeks to make a comparison between the NASA predictive equation and the Cooper 12-minute run test and the Astrand and Rhyming Cycle Ergometer Continue reading...

Abstract

Physical action is a vital part of everyday life. So as to assess the physical fitness of the male and female understudies, there are a few routines to gauge VO2 max. Maximal aerobic power is generally acknowledged as the best measure of the cardiovascular frameworks' practical points of confinement and has been demonstrated to envisage mortality from all aspects in healthy as well as unhealthy people.

Participants

This study involves 167 volunteers. Out of 167 participants, 133 are males. This represents 79.6% of the overall participants. On the other hand, out of 167 participants, 34 are females. This Continue reading...

Abstract:

The understanding of the fluid flow characteristics is best achieved through the Bernoulli’s equation. It is the mathematical statement that relates the characteristics of the fluid and predicts fluid flow behaviors. Fluid flow behaviors differ in different conditions. In an ideal flow, taking the fluid as incompressible, non-viscous, and steady flow, the general formula for Bernoulli’s equation can be used where the Potential Energy, Kinetic Energy, and fluid pressures are accounted for. In other cases, the Bernoulli’s principle can be used to derive the mathematical formulas that best describe the conditions of the fluids and the Continue reading...

A general requirement for an emerging company is to determine the factors that would affect the economy of their goods and services. As part of developing a company, it has been decided that the company that I am supposed to design would specialize in manufacturing liquor. To be more specific, the company would specialize in manufacturing bottles of wine.
The production cost of wine was determined by conducting informal research. The informal research was performed primarily through the internet. According to Wine-Searcher (2014), farmers on average sell their bottles of wine to retailers for about $19. Thus, to proceed Continue reading...

Problem 1:
The amount of initial investment at a rate of interest of 10% and after 3 years to get $4000. This can be used to tell investor’s their return value.

Future value is give, interest rate and number of years.

P = F/ (1+i)n i.e. P = 4000/(1.03)5 = 3005. Interest rate is in percentage

Using Time value of money equation for compound interest

This equation is used for the calculation if initial deposit for a return of 4000 after 3 years at 10% interest rate.
Rate of Interest and number of years are the variables.
We derive the formula from F = P(1+i)n. Placing Continue reading...

Summary

The laboratory work is designed to study the properties of the upward flow of fluid and gas through a column packed with glass beads of different size. The experimental rig Armfield CEL-MKII is applied. The upward flow generates fluidization, namely the state when the glass beads suspend in the flow. The pressure drops of water and air fluidization, as well as the behaviour of glass beads of different sizes are studied. The Carman-Kozeny equation was applied for calculation pressure drop in the system. The calculated values of the fluidization pressure drop correspond well with the experimental values.
