Ozone cracking

high resilience and it is waterproof. Rubber have unique physical properties and chemical properties. Rubber’s stress strain is modelled as hyperelastic. Double bond is presence in the natural rubber. This make the natural rubber is sensitive to ozone cracking and susceptible to vulcanisation. On the other hand, another ingredient that contain in tyre is fillers. Fillers can be used

The intent of existing investigation was to formulate nitrile butadiene rubber (NBR)/high density polyethylene blends (HDPE) blends using industrial waste (MW) and compatibilized by Chloroprene rubber (CR). Results indicated that the minimum and maximum torque increased with increasing HDPE amount in the blends, whereas scorch, and cure time showed the decreasing trend. Increment in HDPE increased the tensile strength, modulus, tear strength, hardness and crosslink density. % tensile strain, % compression

Asphalt is a relatively durable product, which is why it is commonly used on roadways and driveways. However, without proper maintenance it can give way to cracks or holes. Fortunately, it is fairly easy to fix these issues—as long as you address them quickly. So if you are interested in fixing a crack or hole in your asphalt, use these three tips to ensure you get good results: 1. Clean Well Before you do anything, make sure you thoroughly clean the asphalt. Any loose bits of dirt and debris could

single most common point of failure in system security. Ensuring that passwords cannot be efficiently broken is important for encryption algorithms. Due to this, we decided to design a sequential and parallel algorithm that would be successful in cracking a password. Given an opportunity to research any topic where parallel programming may prove useful, we agreed on a brute-force algorithm. In our upcoming project, we would all attempt to design, implement, and analyze the brute-force algorithm.

The Drastic Effects of Air Pollution and Climate Change Air pollution and climate change have an extensive backing from environmentalists and people in general who care about the effects that has on earth. Air pollution is the world 's biggest environmental health risk, with some of the worst problems in developing nations such as China and India. Air pollution is a vast problem which can be fixed, although it will take time. Air pollution kills 3.3 million people a year, including 55,000 in the

There have been many efforts to create systems without considering the users. Furnell (2007) found that while the rules for password creation had been clearly established, websites were doing little to educate users. Campbell et al. (2011) tested a system that did enforce proper password creation but seemed perplexed why this did not reduce password reuse or the incorporation of personal information into passwords. This highlights one obvious problem in password research as there is a hyper-focus

computers from varies password attacks. The chosen software tools are offline password attack (John the Ripper) and (RainbowCrack) which they both are from similar Cyber Security attacks under password cracking tools. John the Ripper is free on multi-platform as it combines various password cracking features in one package. RainbowCrack uses rainbow crack tables that are updated periodically. After calculations, the results are stored, which were obtained in the tables is called a rainbow table. The

Passwords This lab was to discuss the vulnerability of weak passwords. We were thought how to crack our own passwords using a method called “john the ripper”. We also found out how secure various passwords and how long it would take for a desktop Pc to crack these passwords. We looked up various methods and applications to crack passwords. Report Part One: Explain & Preventions Dictionary Attack = A technique used to try and find the user’s password by trying hundreds of different

network vulnerabilities. These hackers are known as white hackers or pen testers. The most popular way to hack into a computer is with a certain attack named brute force. The brute-force attack is one of the most popular cracking methods., it is not just for password cracking. Brute-force attacks can also be used to discover hidden pages and content in a web application. This attack is basically hit and miss until you succeed. This attack sometimes takes longer, but its success rate is higher.

discourse between the collective memory of the community and the individual memory. India’s 1947 partition reveals that there are many different histories to the independence of India and the subsequent creation of Pakistan. By utilizing the text Cracking India, author Bapsi Sidhwa examines the disparities between the two types of memories in order to reconcile the past with contemporary India/Pakistan. India and Pakistan are built from the same foundational nation of India before Partition; thus
