Abstract

As the world is moving further into the core of digital technology, the requirements of computational devices are growing rapidly that are small in size and consume bare minimum energy. Wireless Sensor Networks (WSNs) belong to this category that form a pervasive set of computational devices, deployed in environment for sensing and monitoring physical phenomenon. Sensor nodes find plenty of applications in industries where we need to continuously monitor parameters such as humidity, temperature etc. They are deployed for lengthy periods in environment, mostly at inaccessible places. As WSNs are deployed in a form of a huge network, it Continue reading...

A robotic arm is a kind of mechanical arm, mostly programmable; that mimics the functions of a human arm. The close emulation of a human hand is desired in robotic arms because it increases the number of applications for which it can be used. A typical arm consists of 3-7 metal segments connected by 3-6 joints. A computer controls the robotic arm by rotating the servo motors linked to each joint. The robotic arm also uses sensors to control the movement of the parts to the required extent. Sensors are used to determine the system’s current state. Robotic Continue reading...

Intelligence, surveillance and reconnaissance (ISR) are terms used to describe technologies which enable armed forces to deploy information gathering devices and managing the data collected. Intelligence, surveillance, and reconnaissance information is gathered in the battlefield through physical observations by soldiers, spies, or electronic sensors. The information is then analyzed by intelligence officers and handed to army commanders and other senior decision makers for battle plans formulation. Intelligence is relevant information that enhances the understanding of an enemy’s intents, disposition, and battlefield arrangement (Ramirez, 2014). Surveillance is the act watching and listening to an enemy in a bid to Continue reading...

Objective: Investigate the effect of increasing temperature on enzyme activity.

Introduction: Enzymes are biological catalyst. All most all the functions in the cell are regulated by these enzymes. Except for RNAase, all most all the enzymes are proteins. Enzymes are very efficient and specific in the reaction they catalyze. All enzymes exhibit four common features: I. Enzymes do not make a reaction to occur; they can only fasten the reaction rate. II. Enzyme molecule is not permanently altered by the reaction, though they may be altered transiently. However at the end of the reaction they emerged unchanged and can be used over and over again. III. Enzyme can catalyze Continue reading...

Potentiometers are measurement sensors that use a variable resistor to convert a displacement or angle moved through into a voltage/resistance. Potentiometers operate by moving a contact along a variable resistor thus producing a voltage that is proportional to the position. LVDTs (Linear Variable Differential Transformers) comprise a pair of small transformers sharing a magnetic core. Movement of the core causes the output of one transformer to increase and the other to decrease. The current imbalance achieved through this movement is a measure of the core’s position, and optimum linearity occurs at the midpoint where the two transformers are Continue reading...

2. Traditional mouse-driven monitors rely on the use of point-and-click techniques performed by the user in order to receive the necessary data for the computer to process. When an application is selected, the user double-clicks to select and the program initiates. Affordance is provided through the use of pointers by enabling visual and behavioral properties of an object to indicate how it is used. Touch screen monitors do not provide the same level of affordance. Guidelines in this area are to present consistent visuals so that users can determine if an object is clickable without Continue reading...

I. Introduction
The main objective of the laboratory activity is to study the relationship between temperature and pressure of vaporization of a fluid. In a normal setting, when a liquid is poured into the container, the liquid evaporates. The molecules escape from the container with the liquid and the liquid form changes into a gaseous state. When the container with the liquid is closed, the transformation from one phase to another phase stops as soon as equilibrium is reached. Under such condition, the evaporation rate is equivalent to the condensation rate.
A measure of vaporization is termed as vapor Continue reading...

 IPhone 6

One of the ‘gadget-craze’ that hit the world even as early as last year, is the release of Apple’s new Iphone Model, the Ipone 6. What made the phone different from the others is of course its size. It is bigger compared to the phone it succeeded. I got the chance to personally see the product and when I touched the phone, it felt really light when I was holding it. I was surprised about its weight given its size. Its cameras are clearer. The sample photos are stunning because of the megapixel feature of the phone. I Continue reading...

Abstract

In the laboratory assignment, the experimental investigation of the distillation process is performed. The mixture of dichloromethane and trichloroethylene was separated using the glass distillation column. The influence of power input on temperatures and column flow rate was investigated. Apparently, the power input increases the efficiency of the process. The experiment had three main tasks: study of the variation of the pressure drop, application of refractometer as an express method of binary mixture composition analysis, and estimation of the column efficiency.
It has been proven that the boil-up rate is directly proportional to pressure drop. Although there is some Continue reading...
