devices and applications, there is an ever increasing demand for better coverage and higher data rates. It is worth noting that most data traffic is generated indoors as in homes, offices or in other public hot spots like shopping malls, airports, stations etc. However, mobile signals in these environments suffer from multipath fading, penetration and scattering effects and other losses. Many solutions
Cell phones represent a type of technology that has been around for more than over fifty years; it has only been recently that many people began to use cell phones as a major part of their everyday life. In the past cell phones were for business people to conduct their business, but in today’s society every one owns a cell phone. Cell phones are interesting, useful and also play a major role in our life’s bringing people closer and keeping in touch with one another. Most people do not know and understand
There are many engineering challenges involved in exploring remote areas without human assistance and in particular there is a strong need in advanced Robotics. Robots must be able to function in unknown, unstructured environments. Robots are more précised and it can be used where human involvement is dangerous, such as detecting Land Mines. We have developed a Robot which is completely Autonomous and it can also be controlled manually through Mobile phone. Robot interacts with human with the help

Bases and Alkalis A base is a compound that reacts with and neutralises an acid. The reaction forms a salt plus water. Alkalis are a type of base - ones that dissolve in water. Alkalis are compounds that react and neutralise acids. Like bases, they form a salt and water in the reaction. Alkalis turn red litmus indicator paper blue and they cause Universal Indicator paper to turn blue or purple. Alkaline solutions have a pH value greater than 7. Alkaline solutions feel soapy and are
cellular telephone has evolved and improved a lot over the years. Before we get into the history let us first get the definition for 'cellular'. It's called cellular because the system uses many base stations to divide a service area into multiple 'cells' (1). Each base station consists of a tower and at the base is the equipment to send and receive signals. Now that it cleared up we will look back into the history. To find the first "cell phone" in history we look back to 1928. In 1928 the Detroit
resulting diversity of characters. The plays can be seen to be divided into three general scenes or settings, the court, the tavern, and the rebel's camp, and it is largely the tavern scenes which introduce characters not found in the plays' historical bases. In doing so, Shakespeare of course draws in a more diverse audience, who can perhaps see something of themselves in the full variety of society's characters found in I Henry IV and II Henry IV. Shakespeare's mastery of language and dialect help to
folly will blind them from the truth. Kurt Vonnegut portrays his inner emotions and feelings of the insignificance of religion through the characters of his novel, Cat's Cradle. His satiric approach to a subject that many people base their daily existence upon, challenges the readers faith. As people search for a deeper meaning in their lives, the more confused they become. Only to become entwined in the Cat 's Cradle of life. In the beginning, the reader

unknown concentration. An example could be, a given volume of a solution of unknown acidity may be titrated with a base of known concentration until complete neutralization has occurred. This point is called the equivalence point and is generally determined by observing a color change in an added indicator such as phenolphthalein. From the volume and concentration of added base and the volume of acid solution, the unknown concentration of the solution before titration can be determined. Titrations
department on monthly bases, since they had a variation of products and quality products. The reason why they did this stands to the point that the company produced products in two seasons, fall and spring. The fall products had a cost of $100 dollar per unit because of the more delicate product that required higher material cost, whereas the spring products had a cost of $60 dollars per unit as they needed less costly material. All in, these clarify the fact that they used monthly bases budget. In reasoning
INTRODUCTION Acids and bases always challenged me throughout the years of learning them so when I learned I am going to face this topic again I thought it will be the best idea to a experiment for learning better therefore my aim for this project was learning the fundamentals of this topic. Acids and bases are really important in functioning cell. Majority of them are harmful and they destroy tissues by dissolving protein. For example, sulfuric acid is a strong acid and it has ability to hold the
An acid-base indicator is a substance that undergoes a distinct colour change at or near the equivalence point. The point in the titration at which the colour change occurs is called as end point. Obviously, the titration will be accurate only if the end point and the equivalence point coincide fairly closely. For this reason, an acid-base indicator used in this acid-base titration must be selected carefully in order to obtain an accurate result. Thus, the acid-base indicator used in this
INTRODUCTION We encounter acids and bases on our daily lives. Acids are substances that have a pH of less than 7. On the other hand, bases have pH of greater than 7. They both react to each other to form salt. Acids and bases also exhibit some characteristics like acids are sour and bases are bitter in taste. Acids are also rough in texture while bases are slippery. But you can’t just touch or taste acids and bases as some strong acids and strong bases are dangerous. They contain chemicals that are
The scientific question that was investigated in this experiment is: Does the material used in a filter affect the amount of salt that passes through a filter? The hypothesis was that if the saltwater was run through the different materials listed, then the charcoal filter would filter the most salt out of the water. The independent variable in this experiment is the type of material used in the filter and the dependent variable is the amount of salt left in the filtered water. Some control variables
Acid Base Reactions Acid An acid is a substance which donates proton in water solution. They turn litmus red and form salts when they react with bases.They have PH less than 7. Examples: Nitric acid Nitrous acid Sulphuric acid Base A substance which accepts proton in water solution is called base. Bases turn litmus red and form salts when react with acids. They have PH greater than 7. Examples: Sodium Hydroxide Sodium bicarbonate Magnecium hydroxide Acid Base Reaction A chemical reaction that happens
Kylie Sharron Mr. Van Ness Chemistry Honors Period 4 23 November 2015 Engendering Extreme Frustration in Sophomores: Double Replacement Reactions Lab Background Information: A double replacement reaction, also called a double displacement reaction, is a type of chemical reaction in which two compounds react, and the anions and cations of the two reactants switch places to form two new compounds (products). A general equation for a double replacement reaction would be: AX + BY → AY + BX, along with
separated the land among the people. After the Great Depression, in 1936, the president took more power and gave less to the political parties. Shortly after World War II started the Soviets had an agreement with Latvia to build Russian military bases in their country. The Russians eventually seized power and made Latvia part of the Soviet Union and then created a Communist government. Soon after that, in 1941, the German soldiers invaded Latvia and stayed there until 1944 when the Soviets recaptured
interpretation. GIS is, simply put a database. It is many tables of data organized by one common denominator, location. The data in a GIS system is organized spatially, or by its physical location on the base map. The information that is stored in the database is the location and attributes that exist in that base map, such as streets, highways, water lines, sewers, manholes, properties, and buildings, etc. each of these items don’t just exist in the database, the attributes associated with the item is also
