bugs in the petri dish with dry filter paper and we observed their behavior. The pill bugs were going around the inside rim of petri in circles following each other, almost as if it were a game of tag. The pill bugs never seemed to stop moving, flipping over and were constantly climbing. Some of the pill bugs even tried to escape from the petri dish, but our group was quick to make that didn't happen. As our lab went on, we placed the 4 different pieces of filter paper with solutions on them and

drops of barium chloride was add to the clear supernatant liquid to test for complete precipitation. WASHING AND FILTRATION OF BARIUM SULPHATE PRECIPITATE The filter paper was positioned to cover the entire base of the crucible completely. The clear supernatant solution was decanted by filtration into the pre-weighed crucible with filter paper. A "rubber-policeman" was used to dislodge any particles on the beaker and the beaker was rinsed with warm deionised water. The contents were emptied into

should be seriously concerned gradually. This essay will explain some major design of water treatment filter in the world and it will firstly focus on a variety types of water treatment filters, demonstrating and suggestion of design parameter for water treatment filter; Next, demonstrating the appropriate design for sustainability; and finally, comparing the difference of water treatment filter between developed and developing countries Figure 1,

MCMC particle filter In this project, it is challenging issue to track multi-target as camera motion is unknown. To deal with this issue and targets occlusion, the camera parameters are calculated and targets were also tracked within the 3D coordinates [W. Choi] at the same time. To be specific, it is aimed 1) to solve the multi-object tracking issue by using a single non-calibrated camera, [W. Choi] 2). to deal with complicated scenes in which multiple pedestrians are moving and occluding each

Due to the potential of autonomous vehicles to offer a wide range of advantages to the passengers and therefore influence their daily routines, it is essential to monitor the public’s opinion on this particular technological development. The autonomous vehicle which can be guided to a required destination is developed in the project. The vehicle takes the current position from the GPS and is guided to the destination under the action of microcontroller which is attached to the vehicle. In this work

How to make a superhero comic strip and its subsequent parts Description: Writing an initial superhero comic strip and following it up with sequels is a tedious and time-consuming task. However, it is easy with the new online tools, which are available. The best way to make a superhero comic strip is to use pre-set templates available on the internet. You can use various templates provided by various sites. The easiest are the ones provided by Marvel Comics’ official website and other such websites

The Kalman filter requires an understanding of the processes in the system that shall be observed. Some advantages of this approach are that the method is very robust to measurement noise and does not depend on good initial conditions (after finite time the filter will converge to the correct system state) and by calculating the Kalman-gain and estimating the state-covariance a measure for the confidence in the estimate is available. The downsides of the methods are that they require some data model

the bead flow paused, air pockets were observed moving up through the beads in the top funnel. Researchers hypothesized that each avalanche caused a slight decrease in the air pressure in the top funnel, which stopped the bead flow until air could filter up from the bottom funnel. It was discovered that closing the bottom funnel and warming it slightly with their hands could cause the bead flow to cease. They also found that when both funnels were open to the outside air, the beads flowed without

Subsequently, the autoclave was purged with carbon dioxide and alternately evacuated 3 times, followed by adding purified PO with a large syringe. The autoclave was then pressurized to 5.0 MPa via a CO2 cylinder. The copolymerization was performed at 60°C under stirring for 40 h. The resulting viscous mixture was removed and dissolved in a proper volume of methylene chloride. The residual catalyst was extracted from the product solution by using 500 mL of dilute hydrochloric acid (5%), followed by

processing, the purpose of a filter is to remove unwanted portions of the signal, such as random noise, or to extract useful parts of the signal, such as the constituents lying inside a precise frequency range. Figure 1.1 A block diagram of a basic filter There are two main kinds of filter, analog and digital. An analog filter uses analog electronic routes made up from constituents such as resistors, capacitors and op amps to produce the needed filtering effect. Such filter routes are extensively utilized
