Essays on Timer

There’s a loud, ringing sound. It’s jarring, waking me from the otherwise cozy warmth that is my bed. I am forced to stick my hand, then my entire arm out from under the safety of my bedclothes in order to turn it off. To snooze or not to snooze? It will just go off in another seven minutes. I may as well get up now. The sooner I do, the sooner I get to see my best friend. Groggy, bleary eyes, rubbing sleep from my face and half stumbling I wander into the kitchen, hearing the relations ...

Jack London's ‘To Build a Fire’ takes place within the sub- freezing Yukon of Alaska.

Alongside him is his companion a large wolf dog. Readers are introduced to the setting at the beginning of the story as it states “day had dawned cold and gray” he continues with the statement “there seemed to be an indescribable darkness over the face of things” (London 64). This presents as ...

Routing Information Protocol version 2 (RIP v2) is a routing algorithm that is based on the Bellman-Ford algorithm. As a routing algorithm, it is used to determine the best path between two nodes on a network using distance-vector for path estimation. It makes use of hop count, which is the number of intermediate routers and gateways between a source node and a destination node, to estimate the best path with the maximum hop count put at 15 (Kalamani et al., 2014). This ensures that there are no routing loops in the network. The Bellman-Ford algorithm is based on dynamic ...

555timer

Introduction The 555 integrated circuit (chip) is used in a variety of timer and oscillator applications. A 555 timer is used to provide time delays and oscillations and as a flip-flop element. The device has additional terminals provided to trigger or resetting purpose (Nair, 2006). During the time delay operation mode, time is precisely controlled by an external resistor and capacitor. While working as an oscillator, the duty cycle and the frequency are accurately regulated by two external resistors and a capacitor (Brumbach, & Clade, 2003). 555 is triggered and reset on falling waveforms. A typical 555 timer IC is ...

Organization

Abstract The world is progressing at the speed of light and this is the fact which creates an urgency to measure everything. And when it comes to that, education is not an exception. It has been the continual effort of both the facilitators and the followers of the education system to gauge the level of excellence of a student. In an attempt to do so more accurately, the SAT and the ACT tests came into being. However, the implementation of these tests has been questioned many a times and their credibility is not vouched for unanimously. This report comprises of ...

Introduction

Man is no match to the extreme cold, especially when he travels alone. His skills on how to build a fire are not enough to assure his survival against the harsh weather.

Abstract

The objective of this laboratory experiment is to examine the qualities of projectile motion. Considering the movement of a steel ball in the horizontal plane, the initial velocity that is possessed by the steel ball can be ascertained from the assessed range. Considering the assumed initial velocity of the steel ball, the range of the projectile will be assessed for a variety of initial angles. The initial angles and will be computed by the application of the theory with regards to motion for constant acceleration.

THEORY

Considering a given initial speed demonstrated by v0→, with an initial velocity demonstrated by s0→ that is ...

(1.1) This experiment is about determining the effect of angle of inclination in the acceleration of an object. The independent variable is the angle of inclination of the slope of motion; the dependent variable is the acceleration of the object.

Hypothesis

(1.2) The angle of inclination of the slope is directly proportional to the acceleration of the object. Without initial applied force, the only acceleration of the object would only be due to gravity. Thus, the relationship will follow the equation: a=gsinθ Where a is the acceleration of the object, g is acceleration due to gravity, and θ is the ...

The Pomodoro time management technique traces its roots back in 1980 when Francesco Cirillo developed it. The technique has some basic steps that one utilize to increase focus and freshness throughout an activity with maximum productivity and minimum stress. An individual decides the activity, sets the Pomodoro timer, then works until the Pomodoro timer goes off and takes a break. The part of timing oneself is the most effective in the Pomodoro technique. In particular, timing oneself makes one focus on what one is doing since one must achieve a target before the time lapses. An individual is, therefore, able to ...

The effect of television on children’s behavior is a topic that has continued to evoke interest in psychologists. In the investigations educators suggest that television has replaced other forms of socialization such as school and family, reason being that children spend more time in watching television as compared to time spent in school. Psychological and government experiments together with congress investigations have been implemented with the aim of establishing the effects of television on children behavior. Main interest of the methods is to deduce whether social violence results from the violence portrayed in television programs.

INTRODUCTION

The protocols at the transport layer of the OSI reference model provides an end-to-end data delivery service for application processes to exchange messages over the Internet. Protocols operating in the Transport layer use the services of the Internet Protocol (IP) to deliver messages. Many protocols exist at his layer and one of the most important protocols at this layer is Transmission Control Protocol (TCP) for the delivery of data between the Application Layer and the Internet Layer. The shortcoming of IP to guarantee the delivery of datagrams is overcome by TCP by setting up a virtual circuit between the communicating ...

How different time concepts of two different cultures can cause problems between two communicators

Communication can be difficult especially across cultures. Different cultures each have their own rule sets that facilitate communication even amongst the cultures themselves even though we do not know them. Time is a concept of concern since it varies communication between cultures. All of us are individuals and most likely it is possible that we belong to different cultures. Because of that it is guaranteed that we respond differently with respect to time. Now this is where the problem comes in, time difference. When people of two different cultures communicate, it is like they get into a time warp in which ...

A basic kinetic study of a chemical reaction often involves conducting the reaction at varying concentrations of reactants. In this way, you can determine the order of the reaction in each species, and determine a rate law expression. Once you select a reaction to examine, you must decide how to follow the reaction by measuring some parameter that changes regularly as time passes, such as temperature, pH, pressure, conductance, or absorbance of light. In this experiment we will use color change to derive the initial rates of the reaction. Before coming to lab you should read in your text the section on ...

Introduction

Of the over 6, species of anthozoans found worldwide, the northern Gulf of Mexico only has a few, Renilla mulleri is one of these. Commonly known as the “sea pansy” the Renilla mulleri is an anthozoan colony characterized by elongated white polyps that are vividly luminescent when handled in the dark. Under stimulus, these waves of luminescence move concentrically across the colony. Other characteristics include a short peduncle, which anchors to the substratum and makes distinct trails in the mud and the ability of the colony to use water to inflate itself.. It can be differentiated from the Renilla reniformis by ...

Enzymes are sometimes referred to as biochemistry workhorses because they are utilized by many scientists to speed up a number of chemical reactions. Enzymes are proteins that speed up, or in other words catalyze, specific biological and chemical reactions by increasing the rates of reaction by more than a million factors. An example of these enzymes is Pectinase, which is the enzyme that catalyzes pectin breakdown. Pectin is a part of the cell wall of fruits like tomatoes, mangoes, oranges and apples. Pectins are large colloidal molecules and they are responsible for holding or determining the amount of dispersed particles in extracted ...
