Fingerprint Assignment

FBI 30 Year Old Murder Solved

The case was officially re opened and assigned to the cold case squad doug herout. working with the laboratory technicians and analysts. FBI solved a big criminal case and it got so popular. They found a guy with using his fingerprints. In 1978 61 year old Carroll Bonnet was stabbed to death in his apartment. Police got successful by using his fingerprints. Everyone got shocked when they find the killer after for like 30 years approximately. He was in his house one day and literally the police came up to his house and caught him. When he murdered officers found that he was trying to clean up the blood but badly he left his fingerprints there. When he came out from that building he went to drive the car but he had blood on his left hand and when he opened the door that door had his fingerprints. The police found his car after so many days and sent it to the lab for testing. Lab testers found fingerprints, blood, a pistol from the back and black jacket. In that jacket there was a knife too.

Hybrid and Electric Cars Web Resources

 Electric cars work

Electric cars are something that show up in the news all the time. There are several reasons for the continuing interest in these vehicles. Electric cars create less pollution than powered cars, so they are an environmentally friendly alternative to gasoline-powered vehicles (especially in cities).

The environmental impacts of electric vehicles.

The electric power system is changing and, especially, the electrical distribution system will meet  new features. One of the large changes is a transformation of the transportation sector with the use of electricity, with introduction of electrical vehicles and Plug-in Electric Vehicles (PEVs). This will pose new challenges and opportunities for the electric distribution companies. This paper analyzes the effects of PEVs charging on the local 400 V and 10 kV electric distribution systems in the city of Gothenburg, Sweden, using steady-state power flow analysis. Two different areas representing residential area and commercial area have been simulated for the worst-case scenario, which is simultaneous charging of all the vehicles during the peak load period.

The advantages and disadvantages of using electric vehicles

Electric traction is one of the most promising technologies that can lead to significant improvements in vehicle performance, energy utilization efficiency, and polluting emissions. Among several technologies, hybrid electric vehicle (HEV) traction is the most promising technology that has the advantages of high performance, high fuel efficiency, low emissions, and long operating range. Moreover, the technologies of all the component hardware are technically and markedly available. 

The major challenges facing implementation of electric vehicle

The battery management system (BMS) is a critical component of electric and hybrid electric vehicles. The purpose of the BMS is to guarantee safe and reliable battery operation.

Vehicle Safety

I chose Audi A6 Sedan because it has the good quality and HD reverse camera. Engineered for optimal power and efficiency, the new A6 Sedan takes technology and innovation to a new level. A sleek new design achieves the perfect balance of sportiness and elegance, making this vehicle a standout in its class. Blind spot mirrors are awesome.

Paper airplane lab

Our planes were faster than everyone else 

Parachute experiment

Height-5.3m

Time-20s

Velocity-0.265

Questions and Answers 

1. What adjustments/changes did you make to your design after trying it first time?

Ans. At first when we tried it was only in air for like 5.3 seconds but then we put some tape to make it heavier. At the second time it was in the air for like 20 seconds. It worked really well. 

2. What forces acts the parachute?

1. Ans. Once the parachute  is opened, the air resistance overwhelms the downward force of gravity. The net force and the acceleration on the falling skydiver is upward. An upward net force on a downward falling object would cause that object to slow down. The skydiver thus slows down.
   
   
   3. What changes would you make to transport something heavier?
   Ans. Put equal weight on the wings. 
   

   
   

Transparent Airplane coming out in 2050

Transparent Airplane is a great technology which is coming out in 2050. Engineers decided that In 2050 they will call Airbus instead of Airplane. Future aircraft could be using a bionic structure that mimics the bone structure of birds. Bone is both light and strong because its porous interior carries tension only where necessary.
