Multi Slotted Rectangular Micro Strip Patch Antenna
-Harshvardhan ; Sukhveer Singh
A patch antenna (also known as a rectangular micro strip antenna) is a type of radio antenna with a low profile, which can be mounted on a flat surface. It consists of a flat rectangular sheet or "patch" of metal, mounted over a larger sheet of metal called a ground plane. Microstrip patch antennas radiate primarily because of the fringing fields between the patch edge and the ground plane. For good antenna performance, a thick dielectric substrate having a low dielectric constant is desirable since this provides better efficiency, larger bandwidth and better radiation. However, such a configuration leads to a larger antenna size. In order to design a compact Microstrip patch antenna, substrates with higher dielectric constants must be used which are less efficient and result in narrower bandwidth. Hence a trade-off must be realized between the antenna dimensions and antenna performance. A new shape of multiband hybrid microstrip patch antenna is presented in this paper. A simple and planner structure of proposed antenna fulfils the requirements of L and C band of IEEE standard at very low cost. Proposed antenna structure is obtained by combining Minkowski and invented Koch curve and then this curve and then this curve is applied at four sides of a square patch. Multiband behavior of antenna is achieved and better values of Return Loss (RL), Gain (G) and Radiation Pattern is achieved due to small size. Simulated and measured results of proposed antenna cover ten resonant frequencies (1.00, 1.88, 2.91, 3.57, 4.85, 5.47, 5.70, 6.46, 6.73 and 7.74) ghz in L, S and C band. Better value of gain up to 20.9 Db is achieved. High Frequency Structural Simulation (HFSS) tool is used to simulate the proposed antenna. Read More...

Thermal Analysis of Boiler Tube using Finite Element Approach
-Brijesh Kumar Verma ; Mukesh Shyamkant Desai
In this article thermal analysis of boiler tube has been investigated using Finite volume method (FVM) tool i.e. ANSYS fluent. The governing equations i.e. "Energy equations" for the boiler tube have been solved by using ANSYS-Fluent solver 14.5. Conventional, in a boiler there are two types of tubes are there, first straight tube secondly U or bend tube. When the fluid flow through these pipes several thermal- hydrodynamic losses takes place, which lower the performance of boiler. Even some time it leads to catastrophic failure of tubes due, high temperature-pressure, corrosion, layer separation, scale formation. In this work a 2 dimensional model of boiler tubes has been made i.e. Straight-tube and U-tube using ANSYS design module. Where, comparative thermal hydrodynamic performance has been presented. It has been found that in U tube the performance of fluid is more significant as compared to straight-tube. From the above investigation it has been found that the failure of boiler tube i.e. in Straight-tube and U-tube is quite different. Read More...

Study of Mechanical Properties on Sustainable Concrete using Manufactured Sand and Rice Husk Ash
-D Munisekhar ; K. G. Rahulvarma
As in day to day life, we know that cement and sand is primary materials used in construction. As we know that in the entire world after water, concrete is the second largest consumed material by humans. If the consumption goes on at the same rate, it may get exhausted in the coming future. So we have to find alternatives to replace concrete. Otherwise as we know that concrete is a mixture of cement, sand and gravel. In the manufacturing of cement, it increases the pollution in environment, as it goes on, scarcity of cement occurs as well. A remedy to avoid usage of cement and sand is replacing them partially with the materials like rice husk ash and manufactured sand respectively. We can preserve concrete by finding replacement material for cement, sand or gravel which can give same or more strength to concrete. In past, already many replacements were done by many people for cement, sand and gravel to make better concrete. The present proposal involves replacement of river sand with manufactured sand by 25%, 50%, 75%, 100% and cement with rice husk ash by 10% to get good strength concrete. Use of manufactured sand and Rice husk ash in concrete as replacement for sand and cement respectively is very rare and as both the materials are easily available and are of low cost. It would become the best replacement if it gives good strength concrete. Read More...

Investigate the Black Hole Effect on Zone Based Routing Protocol for Mobile Sensor Network
-Jyoti Saini ; Mr. Pankaj Sharma
Mobile Sensor Networks (MSN) is a collection of mobilized data and sensor nodes which can move separately or task define specifically. Routing is a basic step for data exchange in MSN. The routing protocols designed for ad hoc networks are suitable to MSN because they support mobility but due to resource constraint nature of MSN these protocols are not used directly. Hence we need new protocols. Zone based Energy Efficient Routing Protocol (ZEEP) is one of the new protocol in this direction which is the modified form of famous Ad Hoc On Demand Distance Vector Routing Protocol (AODV). The broadcasting nature of sensors presents a number of security threats to this kind of network. Black Hole Attack is one such massive attack, which consumes more data packets of the network and reasons data loss. That badly affects the performance of the network. In this paper, we investigate this issue, error and proposed a new protocol known as Black Hole affected ZEEP or BZEEP. Our simulation results show that the effect of Black Hole Attack is less in case of BZEEP that proves ZEEP is more secure than traditional AODV in MSN area. For simulation purpose Network Simulator version 2.35 have been used. To support our views we used three quality of service parameters like Packet Delivery Ratio, Throughput and radio frequency analysed those using graphs that shows BZEEP gives high packet delivery ratio and throughput than Black Hole affected AODV or BAODV thus increasing the life time of the network.

-Shubham Kanchar ; Sagar Kapadnis; Vishal Salunkhe; Abhijeet Thombare
Authentication supported passwords is employed mostly in applications for laptop security and privacy. However, human actions like selecting unhealthy passwords associate degreed inputting passwords in an insecure approach area unit. Considered the weakest link within the authentication chain. Instead of discretionary alphabetical strings, users tend to decide on passwords either short or substantive for straightforward acquisition. With net applications and mobile apps stilt up, folks will access these applications anytime and anyplace with numerous devices. This evolution brings nice convenience however additionally will increase the chance of exposing passwords to shoulder aquatics attacks. Attackers will observe directly or use external recording devices to gather user’s credentials. To beat this downside, we have a tendency to plan a completely unique authentication system PassMatrix, supported graphical passwords to resist shoulder aquatics attacks. With a one-time valid login indicator and circulatory horizontal and vertical bars covering the whole scope of pass-images, PassMatrix offers no hint for attackers to work out or slender down the secret even they conduct multiple camera-based attacks. We have a tendency to additionally enforce a PassMatrix example on golem and administered real user experiments to judge its memorability and usefulness. From the experimental result, the planned system achieves higher resistance to shoulder aquatics attacks whereas maintaining usability. Read More...

Numerical Modeling Develop for Plate-Fin Heat Exchanger
-Mahesh Patel ; Pushpraj Singh
Hybridized Carbonate and Solid Oxide fuel cell power plants are currently under investigation to fulfill demands for high efficiency and low emissions. Selection and design of high performance heat exchangers are essential for such applications. In this work, various compact heat exchanger (CHEX) technologies pertinent to gas-gas recuperative duties are presented. The CHEX types considered include brazed plate-fin, fin-tube, micro channel, primary surface and spiral. Based on a comparative rating procedure, two CHEX designs namely, plate-fin and micro channel were chosen for further review. Multiple numerical modeling efforts were carried out to develop plate-fin heat exchanger design recommendations. A model was created for the transient thermal simulation of counterblow heat exchanger partition plates. For this analysis, an alternating direction implicit finite difference scheme was written in the Java programming language to model temperature in the working fluids and partition plate. Thermal stress was then calculated in various partition plate designs for steady state and transient modes of operation. Thermal stress was modeled in two heat exchanger materials, stainless steel 304 and Inconel 625. A primary creep law was developed for Inconel 625 to simulate creep behavior in high temperature (up to 1150 °K) heat exchanger partition plates. The results of the transient thermal simulation clearly show the effect of temperature ramping rate on the rate of heat transfer between the working fluids and partition plate. Thermal stress results confirm that additional stress produced in heat exchanger partition plates during transient operation is negligible for temperature ramping rates consistent with high temperature fuel cells. Based on this result it is suggested that employing slow temperature ramping permits the use of higher performance heat exchanger designs, given that damage generally accrued during transient operation is circumvented. Thermal stress results also show that heat exchanger partition plate aspect ratio (Width/Length) plays a major role on the amount of thermal stress produced within the plate. More importantly, this change in aspect ratio has an even larger effect on creep behavior. Read More...

Analysis and Optimization of Scramjet Inlet using Computational Fluid Dynamics
-Abhishek Kesskar ; Prof. K. D. Sarode; M. G. Patwardhan; Mr. P. V. Patankar; Mr. S. V. Bapat
Scramjets are air breathing engines with no moving parts. They rely on the 'ram-air' effect. This is done with the help of oblique shockwaves. The inlet geometry is used to slow down hypersonic air to supersonic speeds to achieve compression, which is then used to burn fuel and accelerated through a diverging section to achieve thrust. The main challenge in making scramjets viable is the lower Mach threshold of its operating range, which is quite high i.e. Mach 3-4. This paper aims at using optimization techniques in CFD (CFX) to reduce the lower threshold of the operating range of the scramjet to between Mach 2.5 to 3. This is mainly achieved by manipulating the inlet geometry. This is done by simulation of flight in a Mach range with available experimental data, validation of the simulation methodology, and application to a lower Mach domain. Optimization techniques were used to generate geometric parameters which provided positive results in lower Mach ranges. Read More...

-Vishal Ganpat Dalvi ; Deepak Sharma
The proposed work envisages increasing the sampling frequency of Analog to Digital converts which directly affects their speed while simultaneously decreasing the power consumption which increases the practical applicability of the circuits and renders thermal stability. The low power, high speed and area efficient Analog to Digital Converters (ADCs) use widely dynamic regenerative comparators to maximize their power efficiency, operation speed and area. In this work, a new high clock (sampling frequency ) dynamic comparator is proposed based on double tail architecture, where the circuit of a conventional double tail comparator is modified to operate at higher frequencies with reduced energy per conversion (energy required to convert a signal into samples) at low supply voltage. In the proposed comparator, a modification in the form of an extra transistor (control transistor) has been added to the previous circuit along with a reduction in the length of the MOSFET transistor from 180nm to 90nm. This comparator circuit is designed and simulated on the tanner EDA tool. The proposed double tail comparator achieves a maximum clock frequency up to 3 GHz at a supply voltage of 1.2V. Read More...

Comparative Analysis of Different Nitrogen Pre-Cooling Configurations in Helium Liquefaction
-Nibin B ; Arun K; Basil Baby
Liquid Nitrogen is used for precooling in Helium liquefier/refrigerator not only to permit a faster cool down to 80 K, but also to increase the cooling power and/or the rate of liquid Helium production. Transferring cooling power of liquid Nitrogen to the Helium stream primarily involves heat exchangers which offer several choices in terms of configurations and flow arrangements. The decision to adopt one option over another should be based on some practical comparative criteria. A designer has to fix parameters such as number of heat exchangers, number of streams and surface-area of exchangers, flow divisions etc. as they play important roles in the process of heat transfer. An appropriate configuration for a particular Helium plant demands maximum performance. There are also other objectives such as minimization of pressure drop, sizes of heat exchangers and amount of liquid Nitrogen consumed. The optimum configuration would be the one which optimally satisfies all the objectives mentioned. In this work, some potential configurations for Nitrogen precooling have been identified from the literature. These configurations are connected to a Collins cycle. Comparative studies are performed keeping all the parameters of Collins cycle the same and also keeping liquid Nitrogen consumption the same. Parametric studies are performed on each configuration using the process modeling package Aspen HYSYS® V7.3 to understand the sensitivity of each on the overall plant performance. Results generated have been applied to arrive at the optimum configuration for precooling in a selected Helium liquefier/refrigerator plant. Read More...

-Rocky Kumar ; K. K. Agarwal
The idea of the conventional cellular system is that devices are not permitted to communicate with each other directly, especially, in the licensed bandwidth of the cellular network. The entire communications occur via base stations. This paper includes envisioning about a two-tier cellular network which also implicates a macro-cell tier (Base Station to Communication of Device) and also a device tier (Device to Device Communication). Relay of device terminal makes it possible for those devices which are in network and allow doing function them as transmission of relays. It realizes a massive network of ad-hoc. In these scenarios, the two-tier cellular system maintained security for the privacy just to ensure existing macro-cells of BSs performance’s minimal impact. This network needs a design with some smart strategies, proper resources, and intrusion management. Moreover, models of novel pricing have been smartly designed to tempt those devices to contribute to the communication of such types. This paper gives an overview of such challenges that may arrive in two-tier networks. It also proposes some schemes related to prices for several relay devices. Read More...

Design and Analysis of Draw Die for Fuel Filler Cap
-Revan Puri ; Durvesh Dandekar; Milind Gawai; Ajay Gaikwad; Harshwardhan Galave
This paper reports on the initial stages of a combined experimental and finite element analysis (FEA) of a deep drawing process. A deep drawing rig was designed and built for this purpose. Punches and dies of various geometries were manufactured. It has also been observed from the work to date that the speed of drawing plays an interesting role in so far as, the higher is the speed the further is the draw, which is not entirely as expected. The cause of this will be further investigated. If the blank-holder force is not kept within the upper and lower limit of reasonable range it does have a significant effect on depth of draw, with the punch tearing through the bottom of the cup if the force is too high and if too low wrinkling of the flange area occurs.

Design and Fabrication of 360 Degree Flexible Drilling Machine
-M. Kumar ; K. Rajan
The standard drilling machine is commonly found in every industry. Drill machines are the heart of every industry. In industry making holes in parts, sheets and structures is a regular work. Perfect and well aligned drilling needs fixed and strong drills. Some parts can’t be drilled using fixed drills due to low space between drill bit and drill bed. We need to use hand drills in such cases but hand drills have alignment problems while drilling. So here we propose a 360° flexible drill that can be mounted on a table or wall and can be uses to drill holes horizontally vertically or even upside down.

Seismic Analysis of Buildings with Vertical Geometric Irregularities
-Sagar Katwa
Due to the urbanization of the society the need for construction of buildings with varied configurations in both plan and elevation is becoming more important and the concept of buildings with vertical geometric irregularities is being accepted universally. The implementation of buildings with Vertical Geometric Irregularities is very challenging and analysis and design is complicated. In this study 5 models are considered for analysis out of which model 1 is a symmetric building and the rest of the four buildings are asymmetric in configuration. Building models are analysed and designed using ETABS software. Seismic analysis of the buildings is done by Linear Equivalent Analysis Method and Response Spectrum Analysis Method. The buildings with Vertical geometric Irregularities have are susceptible to failure and hence greater care is to be taken while modelling and analysis of these buildings. The criteria for construction are considered as per IS: 1893-2002. The results of symmetric building are compared with the results of asymmetric buildings. The dynamic properties of the buildings i.e. top storey displacements, inters Torey drifts, storey shears, natural time period, mode shapes and the torsional effects are found out. It is observed that the vertical buildings with symmetric configuration yield better results compared to vertical irregular configuration buildings. Read More...

Feeder Protection from over Load and Earth Fault
-Ms. Divya Swami ; Ms. Pratiksha Gaikwad; Mr. Ganesh Bharane; Prof. Jaysheel Dabhade
A busbar in electrical power distribution refers to thick strips of copper or aluminum that conduct electricity within a switchboard, distribution board, substation, or other electrical apparatus. In this project busbar can be protected from the over current condition. Industrial instruments failures have many causes and one of the main causes is over load. The primary of the distribution transformer or any other transformer is designed to operate at certain specific current, if that current flowing through that instrument is more than the rated current, then immediately the System may burn because of over load, through this project we are going to protect the busbar from over load condition. In this project work for generating high current more loads are applied to the circuit; so that the current will be increased. Whenever the over current occurred the circuit will be tripped. To trip the circuit, we are using one relay which will control through our microcontroller. When over load is occurred relay will trip the total circuit and buzzer will on to indicate over load. For protection of bus bar from over current condition first we have to measure the total load current which is flowing through the busbar. Here we are using transformer for measuring the load current and the output of transformer is given to ADC for converting analog output of transformer into digital data. That ADC output is given to microcontroller for monitoring purpose. When current are increases certain limit then we are going to trip the load by using relay. In this project we are using 230v bulbs as a load. We are going to increase the load by increasing the number of bulbs ON. When we ON more bulbs it causes over load condition and microcontroller will detect that and it will trip the total load by using relay. In this project we are using 230v, 7-amp relay for tripping purpose. Here we are using LCD for displaying the total load current which is flowing in the circuit. Read More...

-N. Karthikeyan ; M. Saravanan; M. Deepika
The Agricultural and Industrial sectors are generating numerous volumes of decomposable and non-decomposable wastes. The solid waste generated gases pollutes the environment, consequently contributes to greenhouse effects. Because of these wastes the environment gets polluted by various gases which lead to greenhouse effect. The construction sector also imparts its own part of waste to the environment. There are numerous amounts of agro waste products like rice husk, groundnut shells and ash, corn hub, coconut coir. Focusing the cost of the cement which is an in peak demand we have to concentrate on low cost construction material. This experimental work investigates the possibility of using the groundnut shell ash as a replacement material for the ordinary port land cement. At first, the chemical analysis of the groundnut shell ash was determined to conform the cementitious properties of the cement. The physical properties of the materials (cement, groundnut shell ash, fine aggregates and coarse aggregates) were also determined. The mix design adopted for this experimental study is M30 grade of concrete with 1:1.20:2.90 mix ratio. The fresh concrete tests were carried out to check the workability of using groundnut shell ash in concrete. The cubes and cylinders were casted in the sizes of 150mm x 150mm x 150mm and 150mm diameter with 300 mm height. The specimens were subjected to membrane curing of 7, 14 days. The replacement value changes from 5% to 25 % of ash replacement ordinary Portland cement to groundnut shell ash. The compressive strength decreased as the ash content increased. There was an increase in tensile strength at 15 % of ash content. Read More...

-Trupti Waghmare ; Wakode Amrapali; Patil Diksha; Pawar Disha
In extremely inhabited countries like Asian country, every 3.7 minutes a death swoops in. a number one explanation for the world burden of public health and fatalities is road accidents. The loss of human life attributable to accident is to be avoided. Traffic jam and current are major facts that cause delay to car, as most of the countries follow planned sequence of traffic lights. Typically the accidents also are not detected in time that conjointly in several cases results in loss of life. The thought here is to produce an intelligent stoplight System, which might facilitate the car reach the destination in minimum doable time by providing an adequate route of passage. In conjunction with this a controller is to be work on vehicles, which might facilitate in totally automatic detection of the prevalence of accident and find the vehicle similarly. Read More...

Comparison Two Techniques to Optimizing N-Queens Problem Based on Memetic Algorithm
-Amardeep Singh ; Abhishek Bhardwaj
NP hard problems like N-Queens problem are non-polynomial time problems. In this research study, we use the Simulated Annealing local search based MA (SALSMA), and Step-Counting Hill-Climbing local search based MA (SCHCLSMA) to optimize N-Queens problem and make complexity analysis on the parameters viz. optimal solutions, time and convergence rate with respect to number of iterations. The Memetic Algorithm is a hybrid algorithm, being a combination of the Genetic Algorithm (GA) and a local search algorithm. The performance of the MA is found to be superior to that of a solitary algorithm like GA. The MA solves the N-Queens in two stages. In the first stage, the randomly generated solutions are evolved till they become feasible (i.e., the hard constraints are satisfied) and in the second stage, these solutions are further evolved so as to minimize the violations of the soft constraints. In the final stage, the MA produces optimal solutions in which the hard as well as the soft constraints are completely satisfied. Read More...
