A review on CFD analysis of heat transfer enhancement in a pipe with or without circular insert
High-performance heat transfer system is of great importance in many industrial applications. The performance of conventional heat exchangers can be substantially improved by a number of heat transfer enhancement techniques. A variety of complex, highly viscous liquids are involved that undergoes heat exchange process while flowing through heat exchangers. Because of their vicious nature, they tend to have low flow rates and generally represent the dominant thermal resistance due to their vicious nature, adversely affecting the size and cost of the heat exchanger. The process industry is continuously working to incorporate enhancement in heat transfer. Enhancement techniques can be classified as active methods, which require external power or Passive methods, which require no direct application of external power. The enhanced surfaces are routinely used to improve the thermal and hydraulic performance of heat exchangers.

Survey paper on data aggregation in MANET with advance security protocol using NS2
Wireless sensor networks (WSNs) consist of sensor nodes and these nodes can vary from a few numbers to a highly dense number. Data aggregation is a very important technique in wireless sensor networks through which diverse parameters performance can be increased effectively. Energy consumption by nodes can be decreased using data aggregation technique by eliminating redundancy because these parameters play a vital role in MANET. Wireless sensor nodes are very tiny in size and have limited processing capability very low battery power. This diminution of low battery power makes the sensor network vulnerable to failure. Sensor networks consist of several sensor nodes which co-operatively send sensed data to base station. One of the critical constraints of sensor nodes is the power consumption requirement. As sensor nodes are battery driven, an efficient utilization of power is essential to reduce data traffic inside sensor networks thus reduce the amount of data that need to send to base station thereby enhancing the network lifetime. In this survey paper, our main focus is to know data aggregation, data aggregation strategies, private key, public key, and security concept how to data can be a guard from hackers or malicious nodes. Networks have huge application in habitat monitoring, disaster management, security, and military, etc.

Denoising medical image using level-2 Discrete Wavelet Transform and Bilinear filter
Biomedical imaging focuses on the capture of images for both diagnostic purpose and therapeutic purposes. These technologies utilize radioactive pharmaceuticals (SPECT, PET), x-rays (CT scans), ultrasound, magnetism (MRI), or endoscopy, OCT to assess the current condition of an organ or tissue and can monitor a patient over time over time for diagnostic and treatment assessment. Imaging has become a very important part in diverse fields of medical and laboratory research. Analysis of these different image types requires knowledgeable computerized quantification and visualization tools. Until recently, 3D visualization of images and quantitative observation could only be executed with help of expensive workstations and customized software. Today, much of conceptualizing and inspection can be executed on an inexpensive desktop computer equipped with the appropriate graphics hardware and software. In this review paper, we studied the concept of wiener filter and bilinear filter which help in denoising X-ray and MRI images. Besides this also studied about types of images and various domain of filtering, for example, spatial domain and frequency domain which will help in to carry out research. Image quality will be observed using PSNR and MSE parameters

Review paper on power control technique in VANET for catastrophe message broadcasting protocol
Effectively broadcasting extremity messages in vehicular ad hoc networks is an important issue in VANETs. Real-time good fare message interchange is one of the most crucial subjects in VANET, and well fare message interchange mostly happens between close neighbors. By using this characteristic, we will give power control technologies which depend on connectivity, which diminish the access delay of safety packets. The dominant desire of VANET is to furnish life safety on the road. To obtain this, vehicles make use of two types of safety messages, first one is periodic safety messages in which vehicle speed and location will be given and another one is event-driven messages, which will telecast in case of an emergency environment for example accidents, hard-braking and many more. Our research work will be based upon to control power in control in extremity condition because power is one of the important parameters which we need to utilize efficiently so that optimum result can be achieved. Beside this, we deeply studied diverse routing protocol which will be useful to control power in an emergency situation, attack, and challenges which we have to face in implementing VANET.

A novel approach for comparative analysis of networking routing protocol: Review paper
A wireless sensor network is nowadays very popular important in the field of research because the world is now switching faster from wired communication to the wireless communication. We studied many research papers from various researchers and every research worked on diverse protocol. As we know protocol is classified in the different domain and every domain has its own advantages and limitations. In our research work, our main focus is to enhance the base work in term of network parameters. During the execution of any research, first of all, we have to execute in the virtual environment due to the cost factor. Because if we directly execute in the real world it is not necessary that work would be carried out successfully therefore in this scenario huge loss of money will come into existence. We executed our research work in NS2 simulation environment. WSN is collections of very small sensor nodes which accept information and transfer this valuable information to the base station via shortest routes so that energy consumption would be reduced. WSN has defined diverse routing protocols for the network. There is two main problem exist in WSN, the first one is to design a routing protocol which gives optimization of energy and another security issue due to dynamic topology. There are diverse routing protocols which are classified as their working and their application to different conditions. In our research work, we worked on four routing protocols and integrated these into NS 2 Software. Out of these protocols, we found that ECHERP protocol performance is excellent as compared to other routing protocol in WSN.

An effective approach for extracting noise from digital image and real-time data using filtering technique: Review paper
As we know there is a huge development in image processing with time and latest technology play a very vital role in solving a various problem in so many filed like medical, satellite, control and many more. Pixel is the smallest element which helps to form an image. In this review article, we found that there are various types of images exist in various formats. After that, we studied various types of a filter because these filters help us to fetch out noise from images. Diverse types of noises occurred from acquisition to recognition in an image and to remove them various filters are available and every filter is having own advantage and limitations and suitable for particular types of noise which it can remove efficiently. In our research work, our main target is to fetch out salt and pepper noise. In this article, we studied various types of noises and various types of filter in details from a deep study of various research papers. Our dissertation work will be to fetch out SPN form an image, therefore, a detailed study of the median filter and its extension is carried out. To meet the requirement to expectation three parameters will be calculated PSNR, MSE, and IEF. Noise is random in nature and it can be mixed with an image anywhere therefore diverse noise models were studied deeply.
