Software Requirement Specifications

Software Requirement Specifications 2.1.1 Proposed Method Fig.2.1 Block Diagram of D.A.P.S It is dependent on core Harvard Architecture and ARM9263 choosing individual data and command buses. The ARM9 processor commands are accomplish by means of the five stage pipelining. The clock frequency of the ARM9263 processor is too high evaluated to ARM7 processor. ARM9263 processor might accomplish the instructions in a single clock cycle. This processor also chains gazelle equipment which supports java byte codes. Data acquisition processes, as the name consult to appliances and procedures utilized to accumulate the suggestions. In the most basic form, a technician working the temperature of a range on a section of paper is carrying out data acquire. Development has enhanced, this type of strategy has easy and produced more appropriate, important and effective through electronic apparatus. Data acquiring appliances serve as an significant point in a system. Data Acquisition strategy tying along a wide variety of appliances, such as detectors is used to show temperature, flow level and demand. Communication is depending on the information acquisition appliances, those appliances are interfaced with a device through the transmission port. The more frequently used communicating interface for the inadequate distances is RS-232. In RS-232 the correspondence is serial communication for one appliance to one computer by using communication port. The performance of the RS232 up to 115 K baud (bits per second).RS422 and 485 equally will have the capability to interact more distances with the numerous units. Two common parallel communication interfaces are generally the Centroid and IEEE-488. An analog to digital Converter is a device that can transfer the unbroken physical assortment to a digital number that symbolizes the quantitys shift. The substitution involves concerning quantizing of the input. It is appropriate to propose a small measure of error. An ADC performs the conversion (samples the input) occasionally. The consequences will be the sequence of digital values that have modified a continuous-time and continuous-amplitude analog signal to a discrete-time and the discrete-amplitude digital signal. An ADC is characterized by its bandwidth and its signal to noise. The DAPS cell is analyzed for negative ions recognition. The design RDX TNT are launched into the assortment, as a unique sample and incorporate sample. In equally the cases estimated result is described. The first condition of a DAPS system is a appropriate ion source. The source is usually a beta emitter. In a dry air system the ionic species generate are pre-dominantly N+2 or O+2Positive ions and O−2 negative ions. These ions are referred as reactant ions. When molecules of the illustration species are introduce into the ion source region these molecules will be interact with the reactant ions. A charge transfer will take place creating ions of the sample species. TNT will experience charge transfer reactions, TNT + A → TNT Â ± A, RDX will give the ion-molecule reactions with the reactant ions, RDX + A− → (RDX Â ± A). The abridged ion mobility time corresponds to the molecular weights of the addition compounds [RDX-O (H2O)] −,[RDX-O2]−. Therefore, the resultant IMS plasma gram of RDX contains 4 distinct peaks. These ionic species will move in the direction of the ion gate under the authority of the electric field. The polarity of the final controls, unstable substances form negative ions, most of the narcotics, like heroin and cocaine, form positive ions. In the float region the test ions move subordinate the determine of the utilized electric field. Because to the collision among the sample ions and the substance gas molecules, the interval will be proceeding counting on the mobility of the test ions. Ions with a greater mobility will travel the distance of the substance region in a shorter time. The mobility of the ions might count on their size, mass and shape of the ions. For the individual opening of the electronic gate, a produce of the electronic charge symbolizing assorted ionic species in the preview will arrive at the ion collector detached in time. The range of the ion current is consult to as a plasma gram. The ion mobility spectrometrys distinguished strength is the performance at which separations happen typically on the prescribe of tens of milliseconds. This ability combined with its convenience of use, very high sensitivity, and highly efficient design have authorized IMS as a commercialized product to be used as a schedule tool for the field recognition of explosives, drugs, and chemical weapons. Significant manufacturers of IMS testing devices utilized in airports are Morph and Smiths Awareness. The ion source in the submit IMS is depending on the corona discharge in aim to plane geometry. The happening chamber is created of Teflon cylinder with 50 mm inner diameter. A power in the form of parallel tungsten wires (diameter 100 Â µ m) with comparative distance of 1 mm signifies the plain electrode of the corona discharge. The detail electrode is made of tungsten wire (diameter 50 Â µ m) which is installed in a ceramic tube situated in the axis of the release chamber. The position of this tube is to hold the aim electrode in the demanded position and it also acts as a gas inlet. The range amongst the tip of the wire and the popular electrode can be modified by transferring the ceramic tube together the axis of the discharge chamber. In prescribe to accomplish the maximal ion present was the point to plane length varied in the range 3 12 mm. In the excellent corona the maximal current was discovered at 4 mm point to plane range and the ignition voltage was in the range 2-2. 5 kV. The optimum ion current is restricted by the recombination of ions on the plane electrode (corona grid). The proportion of the ions found by the grid to the ions that move the grid is proportional to the ratio E2/E1, where E1 is the strength of electric field in the move tube and E2 is the strength of electric field in the release chamber. The response region consists of several parallel electrodes, divided by Teflon seals. The extent of the reaction region can be diverse, based on number of used electrodes. The first electrode in the response region is particularly designed and its work is to avoid the dissemination of the test gas into the discharge chamber. Two ports for the gas recess and for the gas outlet are generating into this electrode. The majority of the electrodes have the requirement dimensions similar with the electrodes utilized in drift tube. An electric shutter network is placed at the end of the response region. The shutter grid is one of the most significant parts of the IMS. Its role is to keep the ions in response region and to inject the ions into the drift region. The grid is made of similar wires, located in one plane perpendicular to the axis of the spectrometer. The wires are on the electric potential , where VD is the potential of the drift tube at the place of the shutter, and is closing potential between adjacent wires. This potential creates an electric field perpendicular to the electric field formed by the drift tube. As the ions pursue electric field, they hit the grid wires and lose their charge due to recombination processes. If a short circuit is created between the grid wires then the electric potential of the wires is VD and there is no perpendicular electric field generated by the grid, the cover up is opened. The ions are able to enter the drift region. The generating of the secured grid might manage the resolution and understanding of the spectrometer. This is because of to the influence of the normal electric field to the float electric field. The important electric field immediate the grid is offered by deposition of these two fields. If the vertical field is to strong the gate diminution effect occurs. If the normal field is too weak, the quickly ions can go using into the drift location even if the gate is blocked. A constant position in the spectra is existential in this case. The adequate value of the shutter grid electric field is in the aspect from 1 to 10 of the electric field in the float tube. 2.2 Purpose The objective of these software requirement specifications is to capture the customer requirements both functional and non-functional for the project. This serves as the input for the Software Design Document. 2.2.1 Assumptions Connectivity between ADC board and AT91 board will be available.

Data acquisition is the process of sampling the signals that to measure real world physical conditions and converting the resulting samples into digital numeric values. These values can be manipulated by the computer. Data acquisition systems typically convert the analog waveforms into digital values for their processing. The components of data acquisition systems include: The Sensors that they will convert the physical parameters to the electrical Signals. A Signal conditioning circuitry is used to convert the sensor signals into a form that can be converting to the digital values. Analog-to-digital converters, which converts the conditioned sensor signals to digital values The Data acquisition and processing samples of explosives represents the detection of explosive materials like TNT, RDX, NACRO etc. it is generally called as Ion-Mobility Spectrometer .It is used to detect the explosives based on the drift velocity of the generated ions. Drift tube generates the ions from the samples placed. Based on the drift velocity of the ions, generated current will vary. As Drift tube output is connected to the pre-amplifier, the drift tube output voltage in turn depends on the drift velocity of samples. The pre amplifier output is connected to the ADC board (THS1206), which is integrated with the ARM board (AT91SAM9263). ADC converts the continuous analog signal to discrete Digital values. DAPS appropriate the output voltage of the pre amplifier utilizing ADC, depending on the peak appreciate of the accumulated ADC sample data, move time is calculated. Drift Time chosen by the pattern is opposed with the obtainable library data. If the move time utilized by the sample complements with any of the move time values chosen in the library, alarm will be round and the name of the sudden detected is exhibited along with the Attributes like ADC peak voltage benefits (in volts) time (in milliseconds). The Complete unit kept in a big chamber and that is having high voltage power supply.

The Future of Food

THE FUTURE OF FOOD You might think you know everything about the foods that you eat or place on the plates for your family, but you have no idea. The Future of Food is a documentary that reveals appalling or should I say shocking information regarding our crops that are grown in the U. S. today and how big corporations are taking over and altering the foods that we eat through science, all because of corporate greed.What’s even more terrifying is that majority of consumers have no clue that genetically modified foods are everywhere including the shelves at their local grocery stores. These big biotech agricultural companies are genetically modifying our foods with dangerous pesticides, viruses and foreign DNA, not knowing or really caring about what effects this will have towards the consumers and our ecosystems in the future. Well if you thought that was bad news let me just say that’s only the tip of the iceberg and also to let you guys know that what’s worse i s there is no laws in the U.S. that requires these companies to label the GMO foods. What these large companies do is go and patent every seed they can claim, not just in the U. S. but the entire world, basically stealing the creations of nature and claiming them to be their own, a process known as â€Å"biopiracy. † We all thought we were safe because that’s what the USDA, EPA and FDA are here for, to protect us and make sure that our foods that we ingest are safe, harmless and not contaminated.I’m sorry to say that the same people who run the USDA, EPA, and FDA are the same most powerful leaders of these big agricultural companies. This documentary was such an eye-opener to what is going on with our food supply industry. After watching this film I was so sickened on what our country has become. I mean to be apart of these big biotech agricultural companies, you must be really demonic, no heart and especially no conscience at all. How do these people at the top just keep doing what they’re doing treating the masses like lab rats?I love science and how its contributed so much to our world, but people who take advantage of it such as these large corporations have really taken it to the next level. These biotech agricultural companies are claiming to come to a rescue with a new breed of genetically modified crops that can produce more food for the world, but news flash last I heard was that there are still millions of people out there starving with no food availability.In the documentary they stated that the, â€Å"FDA continues to insist that the U. S. public has no right to know which foods are genetically modified because it might confuse them. † Wow, do I feel insulted as a fellow American. I mean is that what our society has become? Practically everyone in the world including Europeans and Canadians have actually banned any type of genetically modified exports from the U. S. but we are still on this GMO food ban wagon or w e’re just really naive people who have no clue what is going on with our world. As of today, I still can’t believe our own people at the top of our society would exploit their own fellow Americans, but thanks to this documentary for making me aware and educating me as a consumer about these GMO foods. I would definitely recommend this documentary to everyone and maybe the more people that become aware the faster we can ban these genetically modified crops in our food supply.

Pets in Ancient Rome - Free Essay Example

Sample details Pages: 1 Words: 448 Downloads: 9 Date added: 2019/10/30 Category History Essay Level High school Topics: Ancient Rome Essay Did you like this example? In ancient Rome, pets were important. They had a many jobs or uses and all of them had a unique purpose for the Roman people. Dogs, for example, were put into categories as a way to easily recognize their breeding or use and were used for many things. Don’t waste time! Our writers will create an original "Pets in Ancient Rome" essay for you Create order Hounds, such as the sighthounds, have been found in documents stating that they could be used to hunt other animals. Scent-hounds were used less but they could be used to find food or other animals. The Italian Greyhound was used as a â€Å"hot water bottle† if a family member became sick. Their job was to keep people warm. There was also a giant dog known as the Molossus. It was used as a guard and a protection type dog. Dogs were also considered a part of the family. This is something that can still be seen today. Dogs such as the mythical creature Cerberus were described in many stories with the Roman gods. Most gods had dogs, Hades and Artemis owned hunting dogs. Dogs could also have been seen in roman laws as housekeepers and guards for the entire family. Roman people prefered white dogs over black dogs. A black dog would be hard to distinguish from a wolf, but a white one would stand out. Another pet which was used more as a royal pet was the snake. Snakes were seen as a pet of healing, which is why the god Asclepius was shown with two snakes around his staff. It was considered bad luck to kill a snake of any type. Many of the Roman emperors had a little snake as a companion inside their household. Birds such as the parrot were sought for their tongues which were thought to be a good omen. Other birds were found as household pets. In ancient Rome cats were not pets and were rarely seen at all. They were only used by the Egyptians as mouse control. Many Romans considered cats to be a pest instead of a pet. If the Romans saw a cat killing a bird, the scenario would be seen as a poor bird being killed by an evil cat. Horses were used for farming or traveling and not necessarily as a pet. They were admired for their strength and beauty. Wealthy Romans used horses for leisure while the poor used their horses as a tool to help them in their everyday lives. Pets were very important to ancient Roman life. Many pets had uses and qualities that assisted people with everyday chores such as hunting or farming. Other pets were simply enjoyed for their companionship or beauty. Each one was important in its role in Ancient Rome.
