Description of the best fire detection equipment to be installed in the Electrical Switchgear Room, Flammable Liquids Room and the Office.
The best fire detection system to be installed in the Electrical Switchgear Room is the photoelectric smoke detector (FM Global, 2). This is because cables which are necessary in the Electrical Switchgear Room are mostly insulated with combustible materials which would invariably generate smoke as they burn in the event of a fire (FM Global 1). This type of smoke from such smoldering fires (characteristic of burning plastic/insulating) according to the NFPA can most effectively be detected by ...

Lie Detector

Beginning of Lie detector
For around centuries, individuals searched various approaches to exposing liars, looking for clues in the blushing cheeks, tricky eyes, twisting toes and all other body's outward signs. However, this finally reached its initiation in the 1920s, when a police officer with a PhD collaborated with an entrepreneurial secondary school student of Berkeley, California and asserted to have developed a machine that researched straightforwardly inside the human heart. In a couple of years, their machine altered police work, detained headlines, tackled mysterious murders and captivated the country. The concept of using a lie detector rose emerged in the middle period ...

Human factor is the major challenge that stands on the way of the specialists in the field of criminal law. Sometimes, the clues may be confusing and the only way to solve the case is retrieving the answer from the people involved. This is when deception and lie become the ultimate challenge in the struggle for the truth. To deal with this problem, the science offered the criminalists a marvelous solution – the lie detector, the device that recognizes the lie. But is it really that good and accurate? The work of the polygraph is based on reading the basic involuntary ...

Question one

An artificially generated smoke differs from a real smoke from the fire in that the artificial smoke has high velocity. Its pressure is measurable at in terms of few inches WG or some few kilopascals. The smoke is pressurized or passed through a pressured compartment or blowers and extended heat exchangers nozzles. Natural smoke from the fire on the other side has a low pressure of movement.

Question two

Concept Smoke generator is the machine or the device that generates the artificial smoke by heating the smoke chemical above its boiling point turning it into vapor. The concept generator is an ...

1, c) It implies that lie detectors should carefully analyze someone before they conclude whether they are lying or not. There should be more than one clue that they use to make a conclusion. The facial expressions should get confirmed by the voice, words or body movements. The ability to detect a lie depends on the skill of a liar and that of the detector. The person is likely to lie without any detection if they had prepared a good response in advance or if they are of a different nationality from the lie detector. It is also easy to lie to a person one ...

Measuring Heart Beats (ECG)

The heart rate of an individual has been defined as the number of times a heart beats every minute (Edlin and Golanty, 2016). When a heart beats, it pushes a volume of blood into the circulatory system. At some points in the circulatory system where the blood flows near the skin surface, one can feel blood flowing as a result of heartbeat. It is at these points where heart rate is measured. Usually, the heart rate of a person is measured at the carotid artery in the neck, radial artery located in the wrist just below the thumb, or ...

Instrumental Analysis

Mephedrone molecular structure
Nephyrone molecular structure
There are several structural differences between the three chemical substances that make adrenalin distinguishable from both Mephedrone and Nephyrone. The adrenalin molecular structure has a more stable structure more than both Mephedrone and Nephyrone. The adrenalin structure has an extra OH molecule that makes it distinguishable from the Mephedrone and Nephyrone. Several analytical tests can be used to determine this difference.
There are various chromatographic techniques that can be used to test the purity of the adrenalin tablet. The first method is paper chromatography. This chromatographic method is used to analyze ...

A polygraph test measures the pulse, blood pressure, respiration, perspiration and skin conductivity of a test subject, in the belief that the telling of a truth or a lie has an effect that manifests in these physiological indices. Throughout its history and since its invention, the polygraph has enjoyed claims of up to 90% accuracy from its advocates. However, the accuracy of the polygraph has widely been criticized as there is not enough evidence to support these claims. Further, research shows that most studies carried out to establish the validity of the polygraph do not meet scientific standards of quality and rigor. ...

Communication

Communication

Introduction

Radio communication is one of the earliest forms of communication. It involves the transmission of information through electromagnetic waves, traveling at the speed of light. Radio communication has two main components: radio transmitter and radio receiver. A radio transmitter is an electronic device that initiates the communication process by generating radio waves containing information targeting a specific audience. A receiver refers to an electronic gadget that obtains the signals and converts them into an easily understandable format. It consists of the antenna, amplifier, tuner and detector (Lowe, n.d.). The antenna intercepts electromagnetic waves in the air and converts them ...

Abstract

If you ever tried to solve an issue with finding an employee for a particular position in your company, you must know that it’s quite difficult to find a professional. Sometimes this issue is solved simply but sometimes you need a whole raw of tests and interviews to see what kind of person is sitting in front of you and if you can trust him/her with an important job. Big companies hire special managers to find proper workers. And if you have a rather small enterprise, you have to find them yourself. It’s not that easy – an ...

PART ONE

Deception is a conscious and intentional act, usually meant to foster a certain conviction or belief in another person, this belief is however, considered false by the person deceiving. Depending on which type of liar one is, there are certain cues that fall under verbal and none-verbal which can be of help in identifying a lie.
One can be an occasional liar, frequent liar, habitual liar, or professional liar. Depending on the type of liar, one will elicit different behavioral cues which might be difficult to catch but not impossible. The prudent thing to do is establish a baseline ...

Introduction

Natural disasters (e.g. forest fire, hurricane, tsunami) and persistent terrorism attacks remind companies, guests, and staffs of the hospitality industry to be ready for all forms of emergency. Security is not confined to only one element. Rather, it has been categorised into different kinds ranging from property damage prevention to potential injury and death within the hotel vicinity. To enhance security, numerous hotels have used closed circuit televisions, smoke detectors, fire sprinklers, and electronic locks. Hence, there are three types of security, namely, security of systems, security of persons, and physical aspects (Kusluvan et al., 2010). This paper discusses ...

1.0 Lab 1: Heating Value Measurements: Solid and Liquid Fuels with a Bomb Calorimeter
1.1 Introduction
Measurements of heating values can be derived for both solid and liquid combustible fuels using an Oxygen Bomb Calorimeter. The calorimeter measures heat. Heat is not the same thing as temperature. The heat of combustion is called the calorific value. The calorific value is “:the number of heat units liberated by a unit mass of a sample when burned with oxygen in an enclosure of constant volume” (Introduction 2007). The experiment uses the 6100 Bomb Calorimeter. The definition of calorific value in a bomb calorimeter ...

Introduction

Fourier analysis is a field of mathematics that studies how general functions can be approximated or represented by the addition of simple trigonometric functions. Fourier analysis is named after a man who proved that representing a mathematical function in the form of a sum of a trigonometric function simplifies the inquiry into heat propagation. Joseph Fourier envisioned the Fourier series, a concept from which Fourier analysis grew. Presently, vast spectrums of mathematics involve Fourier analysis as a subject. The subject spans through the field of engineering and sciences. In these two fields, Fourier analysis involves the process through which a function is decomposed into simpler functions. The ...

Spot Detectors and Beam Detectors
Question 1: What is the difference between the operation of spot detectors and beam detectors? Provide three situations where the use of beam detectors is recommended over spot detectors.

Answer: Beam detectors and spot detectors work on different principles.

Beam detection is one of the newest technologies in the field of fire alarms. The principle on which beam detectors operate is referred to as obscuration. Bean detectors have the ability to appropriately sense the percentage of light blockage and the likelihood of them giving false alarms is very less. They are quite well able to distinguish between a trouble condition and other conditions such ...

Joseph John Thompson is credited with the discovery of the electron. This was as a result of an experiment he conducted in 1897. Thomas discovered that Cathode rays, which were discovered by Philipp Lenard, could travel a lot further through air than is expected for a particle as small as an atom.
Thomas first produced cathode rays and passed them to a bell jar. Here, they were deflected by a magnet. The path of the rays was detected by their fluorescence on a screen placed in the bell jar. He performed this experiment with different materials as the anode and with different gases in ...

Introduction

The American criminal justice system relies on the knowledge and equipment of many sciences and skills. Forensic evidence has become one of the strongest weapons for the successful prosecution of the criminal offenders. Some scientific theories and tests are so widely accepted and verified that they are virtually beyond criticism. The theory that each person’s fingerprints are unique, for example, has universal acceptance.
Historians believe that the Chinese used thumbnails to sign important documents before the birth of Christ. But it was not until 1870s that a British civil servant in India used fingerprints to record persons on ...
