Studies on Enhanced Strength of Concrete on Use of Industrial Waste Blends Like Red Mud And Iron Ore Slickens
-Deepti Upwanshi ; Nancy Soni
Concrete is one of the most commonly known versatile building materials. The advantages of using concrete are to obtain high compressive strength, very good fire resistance, high water retention qualities, low maintenance requirements, and long service life/ durability. The disadvantages of using concrete include poor tensile strength, low strain of fracture and form work requirement. The major disadvantage is that concrete develops micro cracks during curing. The rapid propagation of micro cracks in concrete under application of stresses that are responsible for the low tensile strength of the material. Other disadvantages include relatively low strength per unit weight. The main reasons for adding steel fibres to concrete matrix is to improve the post- cracking response of the concrete by improving its tensile strength , i.e., to improve energy absorption capacity and apparent ductility of the material, and to provide resistance to cracks and hence causing crack control. The study aimed to identify the optimum percentage of steel fibre reinforcement as the replacement of cement in the M20, M30 and M40 grade of concrete mixes. The percentage at which the SFRC gives maximum workability were also determined in the study. It was observed that the optimum percentage for M20 grade of concrete is 1% as a replacement of cement, whereas its 1.5% for M30 and M40 grade of concrete. Read More...

Feature Extraction Enhancement Techniques in Iris Biometrics Recognition Security System
-Umang Varshney ; Dr. A. K. D. Dwivedi
The accuracy of an iris recognition system is largely dependent upon the technique employed in encoding the local phase of the iris texture so as to extract maximum information. The earliest and most commonly used Gabor wavelets yield a local phase representation distributed over several scales and orientations generating extremely efï¬cient feature vectors. One of the very promising attempts at obtaining a useful phase information is from the ï¬eld of analytic signals and wavelets. In this paper, we suggest that the distinctive ability of the discrete wavelets to simultaneously extract local phase and orientation can be exploited with improved feature extraction for iris recognition applications. In order to test the effectiveness of the proposed method, the reconstructions obtained using discrete wavelet phase are compared with the Gabor and Fourier counterparts. The analysis has been done via Image Processing, Computer Vision and Wavelet Toolbox in MATLAB. Read More...

200 KVA Distribution Transformer Life Time Cost Evaluation Including Environmental Cost
-Akash Sahu ; Shalini Vaishya; Rajeev Chauhan
A large number of distribution transformers are being currently used in the electricity distribution network in India. During purchasing them, it is not sufficient to evaluate and analyze only the bid price of the transformer. There are no-load losses as well as load-losses in the transformer during its lifetime. The cost evaluation of transformers is depends on total owning cost (TOC) method that consist of transformer bid price and cost of transformer losses. Similar to energy cost, greenhouse gas (GHG) emissions are also assigned a price by energy markets. Therefore this study recommended an innovative transformer cost evaluation methodology by introducing the environmental cost (EC) into the conventional TOC method. This environmental cost is coming from the cost to buy GHG emission credits because of the GHG emissions associated with supplying transformer losses throughout the transformer lifetime. It is important to include the environmental cost of transformer losses into the cost minimizing evaluation of distribution transformers. So the transformer with minimum TOC would be the most energy efficient transformer, such transformer are commercially and technically viable. Reduction in power losses in transformer further improves the economy of power industry and impact the global environment. The paper also discusses the case of MPPKVVCL Jabalpur where adoption of such energy efficiency transformer can reduce the electrical power generation requirement due to lower losses and reduction in co2 emissions.

Cement being the costliest material of concrete, there is an urgent need to replace cement in concrete. Hence, to reduce disposal and pollution problems the innovative use of marble powder in concrete by replacing cement and fine aggregate with this material is another alternative of the traditional concrete. The aim of this research is to replace cement and sand by marble waste accordingly in range of 0%, 5%, 10%, 15%, 20% for M30 grade concrete. This research is concerned with the experimental investigations on workability and strengths of concrete and optimum percentage of partial replacement of cement and sand via 0%, 5%, 10%, 15%, 20% of marble powder. Three test mixes were prepared to test the suitability of marble dust in concrete. Mix-I contains 0%, 5%, 10%, 15% and 20% replacement of cement with marble dust in M30 grade of concrete. Mix-II has 0%, 5%, 10%, 15% and 20% addition of marble dust in traditional mix of M30 grade of concrete. Mix-III has 0%, 5%, 10%, 15% and 20% of marble dust as replacement of sand in M30 concrete grade. Ultimately it was observed that strength decreases on replacing cement in concrete, while strength increases on replacing sand in concrete due to filler effect of marble powder. Read More...

Content-Based Image Retrieval using Features Extraction and Rotation Invariant Feature Transformation
-Hemlata M. Rasane ; Jyoti N. Nandimath
Content-based image retrieval uses the visual con-tents of an image such as color, shape, texture to represent and index the image. In this system the visual contents of the images in the database are extracted and described by features. The features of the images in the database form a feature database. Feature database is used for similarity comparison with query image. Then CBIR system gives images relevant to query image from dataset images as a output. Content-based image retrieval (CBIR) by extracting the advantage of low complexity ordered dither block truncation coding (ODBTC) for the generation of image content descriptor. In encoding, ordered dither block truncation coding (ODBTC)[1] compresses an image block into corresponding quantizers and bitmap image. We proposed two image features to index an image are color co-occurrence feature (CCF) and bit pattern features (BPF), which are generated directly from the ordered dither block truncation coding (ODBTC). The color co-occurrence feature (CCF) and bit pattern features (BPF) of an image are simply derived from the two ODBTC quantizers and bitmap, respectively, by involving the visual codebook. We have also proposed a novel feature representation method for content-based image retrieval is rotation-Invariant for checking retrieval accuracy of the proposed method depends on its rotation invariant ability or not.

Reliable and Dynamic Routing Approach for Airborne Mesh Networks
-Syeda Adiba Tahniyat ; Sridevi.H
Low-heights unmanned aerial vehicles (UAVs) joined with WLAN mesh networks (WMNs) have encouraged the rise of airborne system helped applications. In tragedy help, they are important answers for 1) on request universal network system admission and 2) effective investigation of measured ranges. By the by, these arrangements still face significant security challenges as WMNs are inclined to routing assaults. Thusly, the system can be harmed and attacker may control payload information or even capture the UAVs. Modern security benchmarks, for example, IEEE 8 2.11i and security systems of the IEEE 8 2.11s mesh std., are powerless against routing assaults as tentatively appeared. Thusly, a safe routing protocol is basic for making attainable the distribution of UAV-WMN. None of current research approaches have picked up acknowledgment by and by because of their high overhead or solid suppositions. Here, it is the position aware, secure and efficient mesh routing approach. The proposition avoids a greater number of assaults than the IEEE 8 2.11s/i security instruments and the outstanding, secure routing protocol ARAN, without making prohibitive suppositions. In reasonable UAV-WMN situations, this approach accomplishes comparative execution comes about as the settled, non-secure routing protocol HWMP consolidated with IEEE 8 2.11s safety instruments.

-Ruchita P Wanaskar
Now a days we are using digital data in database applications. So the usage of digital data is more as well as the database is more so the performance of the system decreases in terms of the speed as well as the efficiency So for that need of different text mining methods. Data-mining is the process in which we can find the relations in between the data. In this paper, we proposed a discovering frequent sequential patterns for phrases model, for phrases. It also includes finding the hidden information to extract the hidden information using different methods of data mining. Some phrases cannot be understood by the system or have different meaning so for that need of finding meaning or synonym or can say finding the hidden information which is to be extracted using data mining algorithms. However, it is difficult to use these phrases for answering what users want effectively. Therefore, we present a pattern taxonomy extraction model is used for extracting descriptive frequent patterns by pruning the meaningless. The model then is extended and is to be tested by the filtering system. At pattern-based methods outperform the keyword-based methods. that as in this system removing of meaningless patterns reduces the cost of computation & improves the efficiency of the system. The pattern based approach can improve the accuracy of system for evaluating term weights because discovered patterns are FSPecific. Also it improves the effectiveness of updating discovered patterns for finding relevant and interesting information. Proposed system efficiency will increased. Read More...

Data Security in Wireless Sensor Networks using Hash Functions
-Sumayya Afreen ; Sridevi.H
The drawbacks of wireless sensor networks (WSNs) are from the energy and bandwidth, where the data provenance is critical for such kind of networks. The dimension of the provenance grows with the number of nodes traversed by the network packets even after using lossless compression methods that are used for encrypting provenance data. A dictionary based provenance approach is used to in order to address such problems. The size is independent of the number of nodes present in the packet. This approach exceeds other compact provenance mechanisms with respect to provenance size, robust, and energy consumption. Read More...

-Muqtar Ahmed ; Brijbhushan S; Maneeth P. D
concrete is a highly demanded construction material which is used in construction industries which becomes present days high expensive due to the corresponding increase in the demand in construction among which lesser availability of sand is major concern hence there is a need to find alternate for sand. Copper slag is one of the waste material which can be replaced by sand available free of cost thus the cost of construction can be lowered. In this project work cement is partially replaced with Rice Husk Ash as 15% fixed by weight of cement & fine aggregate is partially replaced with copper slag as percentage ranging 0%, 10%, 20%, 30% & 40% by weight of sand for M25 grade concrete. And tests conducted on hardened concrete is compressive strength test, split tensile test , flexural strength test and sorptivity test after specimens are cured for 7, 28 days curing. The effect of Rice Husk Ash and Copper Slag on mechanical properties of concrete were analyzed and compared with normal concrete. In comparison with normal concrete, the compressive strength after 28days is increased in 8.27% for 30%. The split tensile strength after 28days is increased in 32.09% for 30%. The flexural strength for 28days is increased as 15.29% for 30%. And by the sorptivity test is found that, as the percentage of copper slag increases then there will be decrease in water absorption.

An Innovative Human Area Networking Technology using Redtacton
-Amshaleka R ; Amaresen S
All the user-friendly services require technologies that enable communication between people and objects in close proximity. This paper describes a model of human area networking technology that enables communication by touching, a technology we call Redtacton. Human area networking technology for communication between mobile terminals and between terminals that are embedded in the environment has become important. When cables are used for communication between terminals, the routing of the cables is clearly inconvenient. When very weak radio signals are used for the communication, data speeds are reduced by packet collision and other such problems in crowded places such as exhibition sites and security risk from unwanted signal interception is another problem. Technology for solving such problems includes the use of the person body as a signal path for communication. A transmission path is formed automatically when a person comes into contact with a device and communication between mobile terminals begins. Here, the human body acts as a transmission medium supporting IEEE 802.3 half duplex communication at 10Mbit/s. Read More...

Automation & Concrete Investigation of Drilling Parameters and Drilling Machines
-Apratim Mukherjee ; Pradeep Kumar Shrivastava; Pratik Masih
Cutting parameters were evaluated and optimized based on multiple performance characteristics including tool wear and size error of drilled hole. Taguchi's L27, 3-level, 4-factor orthogonal array was used for the tests. It is shown that generally abrasive wear and built up edge (BUE) formation were seen in the tool wear, and the corner wear was also of major importance. Flank wear of the cutting tool was found to be mostly dependent upon particle mass fraction, followed by feed rate, drill hardness and spindle speed, respectively. Among the tools used, TiAlN coated carbide drills showed the best performance with regard to the tool wear as well as hole size. Grey relational analysis indicated that drill material was the more influential parameter than feed rate and spindle speed. The results revealed that optimal combination of the drilling parameters could be used to obtain both minimum tool wear and diametric error. The aim of this study was to investigate the wear mechanisms as well as the hole diameter accuracy, and to introduce the Taguchi method in determining optimum drilling conditions on the tool's flank wear.

By using Practical Reading to Perform Incipient Fault Diagnosis of Transformer Oil using Dissolve Gas Analysis Based on Fuzzy Three Gas Ratio Method
-Ankita Rawat ; Prof. Nisheet Soni
The most common internal fault diagnosis method of power transformer is Dissolved Gas Analysis (DGA) [1-4]. It is a sensitive and reliable technique for the detection of incipient fault condition within oil-immersed transformers. There are a number of methods developed for analyzing these gases and interpreting their significance. These methods are, Roger gas ratio, IEC gas ratio and Duval Triangle[3]. Here we used fuzzy three ratio method to resolve the fault diagnosis problems for oil-filled power transformer. In fuzzy three-ratio method; we considered that the drawbacks of the conventional three-ratio methodlie in: when The ratio crosses the coding boundary, codes changes harply, but in reality the boundary should befuzzied. Based on this assumption, this paper first propose the fuzzy membership functions for codes"0","1","2", then it transfer the conventional logic "AND" and "OR" used in IEC three-ratio method into fuzzy logic and put forward the diagnosing steps of this method. Simulation proves the proposed method can overcome the drawbacks of the conventional three-ratio method can't diagnose multi-fault and no matching codes for diagnosis, thus, it greatly enhanced diagnosing accuracy. In the aspects of experimental work done I have taken data from oil testing lab vidyut bhavan Nagpur. Read More...

-Mahammad Meharaj ; Brijbhushan S; Maneeth P. D
In the process of the growth of the industry large quantum of concrete is being utilized to cater the requirements of the industry, which requires huge raw materials in the production of the concrete for construction. Out of all the raw materials of concrete, lesser availability of the sand is a major concern in the construction industry. Day by day sand is getting costlier which directly increases cost of construction hence there is a need to evaluate the possible alternate materials that can be used as substitute in concrete without losing any of the properties of the concrete which are economically and easily available. The present work has been carried out with M25 grade concrete with w/c ratio 0.45. Bottom ash is replaced in 10%, 20%, and 30% by weight to the natural sand. Polypropylene fibers and WPE fibers are added as 0.75% and 0.25% by weight of cement respectively. The effect of bottom ash replaced with natural sand with addition of polypropylene fibers and WPE fibers is compared with that of the conventional concrete at different curing period, the optimum content of the bottom ash is found to be at 20% with Polypropylene fibers and WPE fibers are added as 0.75% and 0.25% by weight of cement.

Fine Grained Two Factor Access Control for Web Based Cloud Computing Services
-Preeti Math ; Syeda Asra
A virtual host computer system that enables enterprises to buy, lease, sell, or distribute software and other digital resources over the internet as an on-demand service is cloud computing. Though the new paradigm of cloud computing provides great advantages, there are meanwhile also concerns about security and privacy for web based cloud services. A multi-factor authentication and access control system for web-based cloud computing services is developed. In the proposed authenticated access control system, an attribute-based access control mechanism is implemented with the necessity of both user secret key and a trusted security key response. The login of the user is secured by one time key password system (OTP) and each login is secured with session keys i.e. The user is allowed to work only for a permitted time period. A user cannot access the system if she /he does not hold all the three factors: the OTP, secret key, secret key response, the mechanism enhances the security of the system, especially in those cases where many users share the same computer for web-based cloud services. In addition, attribute-based control in the system also enables the cloud server to restrict the access to those users with the same set of attributes while preserving user privacy, the user .The cloud server only knows that the user fulfills the required predicate, but has no idea on the exact identity of the user the cloud holds the user with attributes and the polices. The cloud servers cant access the files of the user i.e. the files stored are in an encrypted format the encryption key is given by only the user. Read More...
