Determination of eye end for natural fiber reinforced hybrid composite mono leaf spring

The automobile industry has shown interest in the replacement of conventional materials with composite due to its property of high strength ratio. Reducing weight while increasing or maintaining the strength of the product is highly important to research issue in the modern world. For this purpose, the material selected was jute fiber and carbon fiber in Epoxy resin.  Present work aims at determining the suitability of jute fiber reinforced hybrid composite to replace conventional multi-leaf spring. Various combination of jute fiber and carbon fiber in the epoxy resin is analyzed with respect to deflection. For this, a parabolic mono leaf spring is modeled in solid edge software and analyzed using simulation tool FEA. As eye end plays a pivotal role in attaching the leaf spring to the frame and determining is the capability to carry loads the spring is modeled with the eye end. Here again, two different possibilities are analyzed. In one case steel eye end is bolted to the Natural fiber reinforced hybrid composite (NFRHC) mono-leaf spring and in another, the eye end is made from the same composite. The two types are then statically and dynamically analyzed using ANSYS software. It is found that NFRHC leaf spring with steel eye end bolted to it has more stresses and lower strain energy compared to bonded eye end NFRHC leaf spring. While the Natural frequency of composite leaf spring is higher than the conventional leaf spring resonance will be reduced Hence NFRHC spring with bonded eye end is considered a suitable replacement with a weight reduction of 80% from that of conventional steel leaf spring.

Wireless detection and alerting of rash driving and accidents using smart device

Rash driving is most dangerous for people. Risky driving primarily includes heavy driving under the power of alcohol, is the major grounds of traffic accidents throughout the world. They provide an early detection to alert the dangerous vehicle maneuvers related to rash driving. There are lots of sensors used in various techniques to detect the rash driving. For this entire detection of rash driving, we require only a smartphone. We are going to use accelerometer sensor on the smartphone. After installing a program on the mobile phone, it will compute acceleration based on sensor readings and compare them with typical unsafe driving patterns extracted from real driving tests. The application allows the owner to track their cars. This application sends a notification to owner mobile regarding the car rash driving if any. It also sends the location of the car to the owner after every ten minutes. We can change this time interval.

Effect of nano-silica on mechanical properties and internal structure of pozzolanic concrete

In this research work, advancement of nanotechnology is used in order to improve performance characteristics of pozzolonic concrete (concrete having 30% class F fly ash in replacement of cement) with use of nano-sized silica (SiO2) particles, known as Nano-silica. This study may be considered as an important step towards better understanding the use of nano-silica in concrete as a remedy to overcome drawbacks of the use of pozzolans (drawback like late strength gain of hardened concrete). This research program aims at 1) further understanding the behaviour of cementitious materials when amended by nano-silicon various physio-mechanical properties (workability, compressive, tensile, flexural strength etc.) of pozzolonic concrete and 2) exploring the effect of this enhancement on the microstructure of cement matrix using SEM. The experimental program that was conducted included a laboratory investigation of concrete mixtures in which nano-silica was added to the compound cement and Class F fly ash. Three ratios of nano-silica (0%, 3% and 6% by wt. of the cementitious compound) were used in concrete mixtures to examine the extent and types of improvements that could be imparted to concrete. The conducted experimental program assessed these improvements in terms of mechanical properties and internal structure of the mixtures under investigation.

Study on road accident and improved safety measures of road accident

Road accidents are an outcome of the interplay of various factors, some of which are the length of the road network, vehicle population, human population and adherence/enforcement of road safety regulations etc. Road accident causes injuries, fatalities, disabilities, and hospitalization with severe socio-economic costs across the country. Road traffic injuries cause considerable economic losses to victims, their families, and to nations as a whole. Almost 90% of the world's fatalities on the roads occur in low- and middle-income countries, even though these countries have approximately half of the world's vehicles. Half of those dying on the world’s roads are “vulnerable road users”: pedestrians, cyclists, and motorcyclists. Without action, road traffic crashes are predicted to rise to become the 7th leading cause of death by 2030. There are a total of 1, 03,933 km of National Highways in India and out of the total length of 1, 03,933 km of National Highways, 57,511 km is with the State Public Works Departments (State PWDs), 32,155 km with the National Highways Authority of India (NHAI), 1616 km with NHIDCL and 4,550 km with Border Roads Organization (BRO), balance length of 4,642 km is yet to be entrusted to the executing agencies. Although National Highways constitute nearly about 2 percent of the total road network as on 31st December 2015, they carry 40 percent of the total road traffic. The capacity of National Highways in terms of handling traffic (passenger and goods) needs to be in pace with the industrial growth. India has one of the largest road networks of over54.72 lakh km. It comprises of National Highways, Expressways, State Highways, and Major District Roads, Other District Roads and Village Roads as shown below.

Cryptography techniques: A survey

In recent years network security has become a very important issue. Encryption has come up as a solution and plays an important role in data security system. Several techniques are required to protect the shared data. Most commonly used encryption algorithms in the domain of cryptography firstly to identify their weaknesses and vulnerabilities and secondly to identify the aspects of those weaknesses which will be avoided by the correct implementation. In this paper, we provided different types of encryption algorithms that are existing and literature survey of those algorithms.

Design of low power delay efficient Vedic multiplier using reversible gates

In early days of computers, multiplication was implemented generally with a sequence of addition, subtraction and shift operations. There exist many algorithms proposed in the literature to perform multiplication, each offering different advantages and having the trade-off in terms of delay, circuit complexity, area occupied on-chip and power consumption. Latency is the major issue of computing a function. Simply it’s a measure of how long the inputs to a device are stable is the final result available on outputs. Throughput is the measure of how many multiplications can be performed in a given period of time. The multiplier is not only a high delay block but also a major source of power dissipation. Normal multiplication process involves generation of partial products, an addition of partial products and finally, total product is obtained. So the performance of the multiplier depends on the number of partial products and the speed of the adder. The reversible computation is one field which assures zero power dissipation. Thus during the design of any reversible circuit, the delay is the only parameter that has to be taken care of. Hence reversible Urdhva Tiryakbhayam [UT] Multiplier had been proposed for reversible calculations. Vedic multiplier based on the Urdhva Tiryakbhayam algorithms provide the best results in terms of delay, area, and power.
