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.

Characteristic behaviour of crush glass fibers on the strength of concrete tile: A review paper
The effect of glass fiber on flexural strength, split-tensile strength, and compressive strength Was studied for different fiber content on M-20 grade concrete designed as per IS 10262. The Maximum size of aggregates used was 20mm. To study the effect on compressive strength, Flexural strength, split-tensile strength 6 cubes, 6 prisms and 6 cylinders were cast and tested. After that, a practical application of GFRC in the form of cement concrete tiles was taken into Consideration and no special technique was used to produce these tiles. The thickness of the tiles Was 20mm and maximum size of aggregates used was 8mm. The water-cement ratio was kept Consistent and the admixture content was varied from 0.8 to 1.5 percent to maintain slump in Between 50mm to 100mm. The size of short fibers Used was 30mm and the glass fibers were alkali resistant. The effect of these short fibers on wet Transverse strength, compressive strength, and water absorption was carried out. Six full-sized Tiles 400mm*400mm*20mm were tested and the results recorded. Pulse velocity tests were also conducted.

Smart Eye for Blind Person using Raspberry Pi
A camera-based label reader is used to help blind person which helps them in reading names of the label on the product. The camera captures the label image of the product which is in front of it, detects the product label image and the image is separated using open CV library. The image label is then identified and can be heard by the blind person through voice. Earphones can be used for this, connected to the audio jack. The kit used for execution is the Raspberry PI which consists of various slots. This system also helps to find obstacle which appears in front of the blind person with the use of sensors.
