A Review on Crosstalk in DSL Systems
-Nitish Malik ; Mrs. Lovely Chawla
Crosstalk is a serious problem in next-generation DSL systems such as VDSL. Several non-linear crosstalk cancelers and pre-compensators have been proposed to address this. Unfortunately they all suffer from high complexity, DFE error propagation and/or require modification of CPE. In this paper we propose the use of a simple non-linear adaptive filter for remove crosstalk canceler in upstream transmission. Adaptive filter for crosstalk cancel we use least mean square (LMS) technique and cancel crosstalk at near end in DSL line. Read More...

A Study of Chemistry Laboratory Facilities in Senior Secondary Schools
-Dr. Gopal Krishna Thakur
Chemistry is an experimental science which gives opportunity to the learners to familiarize with the scientific methods and get them doing important scientific activities like observing, measuring, analyzing and describing. It also provides an opportunity to the teacher to teach chemistry as a way of investigation. Laboratory work is an essential component of chemistry curriculum. The development of powers of observation, measurement, prediction, interpretation and decision making are dependent on laboratory work experience of students. But unfortunately the present curriculum transaction approach in chemistry, like all other sciences, relies mostly on abstract thinking, writing long formulae and complex structures and handling complicated equipments. This method of teaching chemistry has discouraged both teachers as well as pupils. The main reason for this process is that the laboratories in most of the schools today are not adequate to get all science students actively engaged in experiments. Rather, schools heavily resort to either no experiments or if there is any urgency then as minimum as they can. Also, experiments which form a part of the syllabus are not relevant or interesting and are not related to the issues connected with the real life situations. Besides this, there are various constrains such as large teacher-pupil ratio in the class / laboratory, lack of physical facilities for performing experiments as required by the rigid and time-bound heavy syllabus. This paper discusses the outcomes of a study which attempted to examine the chemistry laboratories facilities at senior secondary schools of Delhi – NCR. Read More...

An Efficient Sparse Sampling Approach to Magnetic Resonance Imaging
-Arvinder Kaur
It is well known that a nuclear resonance magnetic field is used in capturing a MRI image in medical field. When one goes for MRI, he is kept under the nuclear field scanning (approximately under 64 MHz range) for a wide span of time. This instead of helping adds harm to patient’s health. A new technique sparse sampling or compressive sensing has come into the picture, by using which number of measurements or samples taken can be reduced to a very little number than that were used initially and thus number of radiations bombarded to patient can also be reduced to a great extent. The image we get is little tolerated on PSNR value but has an observable quality. This appear focuses on reducing the recovery timings of MRI image by fitting compressive sensing to MR imaging.

Survey on the challenging issues in energy efficient methods for routing in heterogeneous wireless sensor networks
-Shruti Halkude ; S K Padaganur
Our work in this report stems from the fact that most of the open vehicle routing problems are similar to the ones in sensor networks from the assumptions and constraints point of view. Hence, it makes sense to use those techniques in the wireless sensor networks domain such that we can find certain most required solutions for some problems being faced in WSNs. To provide a baseline that this approach is achievable we have proposed one data collection protocol called EDAL which stands for Energy- efficient Delay-Aware Lifetime- balancing data collection protocol. This algorithm design of EDAL provides proof for one result from OVR that the problem formulation is inherently NP-hard. Hence, our research work lays emphasis on both centralized heuristic so as to reduce the computational overhead and a distributed heuristic so as to make the algorithm scalable for large-scale network operations. This data collection protocol, EDAL, that we are introducing is aimed to be closely integrated with compressive sensing, which is a technique that ensures considerable reduction in total traffic cost for collecting sensor readings under loose delay bounds.

A Preliminary work on Non Invasive Technique for Measurement of Hemoglobin
-Saravana Kumar. T
Hemoglobin (Hb) is the most important vital parameter of red blood cells. Its level in human body is a vital analytic parameter for diagnosing anemia in both long-term and severe conditions. At present, invasive techniques are employed to quantify the Hemoglobin absorption, by which blood is sampled out from the patient and followed by laboratory analysis. Besides from the irritation of taking blood samples, an additional disadvantage of this technique is the time delay between the collection of blood samples and its analysis, which is not suitable for real time patient monitoring under severe condition and rural area with inadequate testing facility. This paper presents an optical non-contact technique that provides Hb concentration measurement. The absorbent coefficient of blood differs at different wavelength this certainty is used to determine the optical property of blood. In this newly developed system, absorption of light by oxygenated and deoxygenated hemoglobin is measured at two wavelength 660nm and 940nm. The particular wavelength of light is obtained from red and IR LED. Constant current circuit is designed to drive the LEDs. Transmitted light through an area of skin on finger was detected by a photodiode. Ratio of Red LED to IR signal after normalization is calculated for determination of Hemoglobin. Signal acquisition by this technique is totally noninvasive. Read More...

Passive Heat Transfer Augmentation Methods in a Circular Tube: A Review
-Sumit S. Kalmegh ; Pawan A. Sawarkar; Pramod R. Pachghare
The present paper is a review of the passive heat transfer augmentation in circular tubes used in the recent past and these techniques will be useful to designers while implementing in heat exchangers. Passive techniques, generally uses surface or geometrical modification to the flow channel by incorporating inserts or additional devices to increase the heat transfer rate.As the manufacturing process of insert is simple and cheap, so these techniques can be easily employed in an existing heat exchanger. Inserts in a heat exchanger tube generates the swirls, which directs fluid in the Centre towards the heated wall and fluid near the heated wall towards Centre. This phenomenon results fluid flowing in a curvilinear path, which promotes mixing and increase in heat transfer rate. Read More...

Utilization of High Calcium Fly Ash as Filler Materials in Bituminous Concrete Mixes for Flexible Pavement
-Gatesi Jean De Dieu ; M.H.Lunagaria
A bituminous paving mixture is a mixture of coarse aggregate, fine aggregate and bitumen mixed in suitable proportion to result strong and durable mix to withstand traffic load. In this paving mix, normally cement is used as filler material. A study has been carried out in this study to explore the use of high calcium fly ash, a by-product of a coal based thermal power plant in bituminous paving mixes. For comparison, control mixes with cement and has also been considered. Marshall Test has been considered for the purpose of mix design as well as evaluation of paving mixes. It is observed that the mixes with high calcium fly ash as filler exhibit marginally inferior properties compared to control mixes and satisfy desired criteria specified by a much higher margin. Hence, it has been recommended to utilize high calcium fly ash wherever available, not only reducing the cost of execution, but also partly solve the binding properties. The results obtained showed that the high calcium fly ash could improve the properties of bituminous mixes for flexible concrete. Read More...

-Gatesi Jean De Dieu ; M.H.Lunagaria
The growing of infrastructures are the mostly compromised now day for making the mobility of people and goods. In this case the development of any country increases when there is sufficient infrastructures. The roads constructions is the mostly infrastructure promoting quickly development of any country. The pavement materials are required to construct the good roads which helping to connect the different locations. The natural aggregates are occupied the 75% of concrete volume, therefore it is very interested to find the alternative materials which can replace the natural aggregates in order to save environment as well as the economically. The steel slag is the co-product of mills steel industry in which the pig iron are molted in BOF and EAF for reproducing the waste steel materials that can be used as coarse aggregates in place of natural coarse aggregates. This material is strong enough because of its composition of steel for high percentage. The main objective of this research is to check the suitability of coarse steel slag aggregate in concrete mixture. The engineering properties were studied for materials as well as the fresh and hardened concrete.The slump, compacting factor and unity weight tests have been evaluated for fresh concrete and showed that as increment of steel slag % and also the properties improved. The compressive and spilt tensile strength was evaluated by using Indian standard method.

Earthquake Risk Reduction Development and Disaster Management Programme in India
-Hitesh Sharma ; Dr. Govardhan ; Dr. Shirish V. Deo
A number of groups in the country have carried out post-earthquake reconnaissance studies of the recent damaging earthquakes. However, we are yet to develop a formal learning from earth quakes programme which will ensure that reconnaissance of all damaging earthquakes are Carried out in a systematic manner and the findings disseminated expeditiously.The countryis yet to formally take up activities in seismic micro zonation. There is not much activity inthe area of earthquake prediction. Data sharing remains a major handicap; we have yet todevelop mechanisms for open data sharing. There are not much inter-institutional or inter-disciplinary collaboration activities in thecountry. Except the DEQ, none of the institutions in the country have strong groups ofengineers and earth scientists working together on earthquakes. The result is that bothgroups, engineers and scientists, often tend to have a rather narrow view of the earthquakeproblem. Similarly, architects, town planners, and social scientists have no involvement inearthquake issues. The Himalayan Seismicity programme of the Department of Science andTechnology has enabled nurturing of a reasonable level of activity in the area of seismology. A similar programme on earthquake disaster mitigation needs to be operated by a majornodal agency in the country to nurture the research, development and extensional activities.A vibrant earthquake industrywherein earthquake-related services and products can beconveniently made available within the country on a commercial basis is yet to develop(Murty et al., 1999).India has been traditionally vulnerable to natural disasters on account of its unique geo-climatic conditions. Floods, droughts, cyclones, earthquakes and landslides have been a recurrent phenomenon. About 60% of the landmass is prone to earthquakes of various intensities; over 40 million hectares is prone to floods; about 8% of the total area is prone to cyclones and 68% of the area is susceptible to drought. In the decade 1990-2000, an average of about 4344 people lost their lives and about 30 million people were affected by disasters every year. The loss in terms of private, community and public assets has been astronomical. Read More...

A Review on Experimental Investigation of Natural Convection Heat Transfer with a Special V fin Array
-Sawan A.Wani ; S.M.Shaikh
Natural convection from vertical surfaces with large surface element is encountered in several technological applications of particular interest of heat dissipation from electronic circuit. Natural convection represents an inherently reliable cooling process. Because of boundary layer development, the tall vertical fins restrict the heat transfer enhancement. . This heat transfer enhancing technique was investigated for natural convection adjacent to a vertical heated plate with a multiple v- type partition plates (fins) in ambient air surrounding. In order to enhance the heat transfer, V-shaped partition plates (fins) with edges faced upstream were attached to the two identical vertical plates. The V-type partition plates with two different heights were tried. The heat transfer in the downstream region of the partition plate is markedly enhanced when the plate height exceeds certain critical values because of the inflows of the low temperature fluid into the separation region. It was observed that among the three different fin array configurations on vertical heated plate, V-type fin array design performs better than rectangular vertical fin array and V-fin array with bottom spacing design. The performance was observed to improve further, with increase in the height of the V-plates. Read More...

-Ravi Sharma ; K K Thakur
Enrichment of heat transfer rate due to helical coil heat exchanger has been reported by many researchers.
Helically coiled heat exchangers are used in order to obtain a large heat transfer area per unit volume and to increase the heat transfer coefficient on the inside surface. This paper deals with the PCD analysis of helical coiled tubular heat exchangers by CFD simulation. Because the geometry is very important factor to enhance heat and mass transfer for any type of heat exchanger. The results are validated by the results obtained by Mr. Shiva Kumar and Mr. K. Vasudev Karath’s research, And CFD results are also compared with the result obtained by the simulation of helical coil tubular heat exchanger of the same length and different pitch circle diameter over single mass flow rate underneath identical boundary condition taking by Mr. Shiva Kumar. Results determined that as we increase PCD from 40 to 60 pressure drop is decreasing due lesser centrifugal force on fluid particles hence the heat transfer rate is also decreased.

A Survey Based on Quality of Service (QoS) and Multipath routing in Mobile Ad Hoc Networks (MANET)
-Vanjara Ravikant T ; Chirag K Gohel
Due to various characteristics of MANET, it is very challenging. QoS is crucial and very important concept for multimedia or real time traffic application in MANET. QoS is very difficult to guarantee in MANET because of its changing topology compared to wired network. Different QoS metrics i.e. delay, throughput, bandwidth, jitter, energy and link stability is important. Multipath routing is used in order to support QoS. In multipath routing, there are multiple routes between the sender and receiver while exchanging data. But QoS parameters is important while exchanging data between sender and receiver for real time and non-real traffic applications. There is lots off ongoing research on QoS but no proper solution is suggested yet. This paper presents various issues, description and challenges of QoS and multipath routing. Read More...

Filler-Slab as a Continuous T-Beam Slab
-Ayush Srivastava
Shelter is amongst the three basic human needs but now-a-days, about two-third of the total Indian population do not have their own shelter. This two-third population belongs to the middle and lower income class. These people find it difficult to construct their houses at an affordable cost by using conventional construction technology. It is found in many cases that people serve their whole life constructing their own house, but fail. The
mission and dream of these people can be achieved by appropriate use of cost effective and innovative construction technology. As a whole, the housing shortage of the country can be overcome within lesser funds, without compromising with the quality control and structural stability of the structure. My this work is in continuation with the paper entitled “Cost Effective and Innovative Housing Technologyâ€, presented in IJSRD Vol. 2, Issue – 6, pages 27-29. In this work I have shown the demonstration and use of Filler-Slab in building construction to reduce cost of construction as well as the dead load of the structure. This technology also aims at increasing the strength of the slab as compared to RCC slab.

An Energy Efficient Hybrid Clustering Algorithm for Wsns to Increase Network Lifetime
-Kanchan Deep Nagi ; Gagandeep Singh
Wireless Sensor Networks (WSNs) consist of hundreds of small and cost effective sensor nodes. Sensor nodes are used to sense the physiological or environmental parameters (e.g. temperature, pressure, etc.). For the connectivity of the sensor nodes, they use wireless transceiver to send and receive the inter-node signals. Sensor nodes, because connect their selves wirelessly, use routing process to route the packet to make them reach from source to destination. These sensor nodes run on batteries and they carry a limited battery life. Clustering is the process of creating virtual sub-groups of the sensor nodes, which helps the sensor nodes to lower routing computations and to lower the size routing data. There is a wide space available for the research on energy efficient clustering algorithms for the WSNs. LEACH, PEGASIS and HEED are the popular energy efficient clustering protocols for WSNs. In this research, we are working on the development of a hybrid model using LEACH based energy efficient and K-means based quick clustering algorithms to produce a new cluster scheme for WSNs with dynamic selection of the number of the clusters automatically.

AODV Routing Protocol in VANETs in Comparison with OLSR and DSR
-Rajan B. Upadhyay ; Hitesh C. Patel
Vehicular Ad hoc Network (VANET) is a new communication paradigm that enables the communication process between these vehicles which acts as nodes in the network. Various methods of data dissemination in VANET are used to inform the vehicles about the dynamic road traffic conditions for achieving safe and efficient transportation. Ad-hoc On-demand Distance Vector (AODV) is a reactive routing protocol designed for the ad-hoc networks. AODV is an unicast routing protocol which establishes a route only when a node wants to send data packets. AODV involves route discovery and route maintenance process. Due to large delay in the route discovery process and due to route failure which may require a new route discovery process, the data transmission rate decreases and network overhead increases. In this paper we have discussed AODV protocol and its comparison with OLSR and DSR routing protocol. Read More...

A Hybrid Agglomerative Method for Color Image Segmentation
-Manish Kumar ; Meenu Saini
This paper proposes a hybrid method of image segmentation by using k-means and agglomerative methods of image segmentation. The K-means method is used to find optimum number of clusters with the help gap method and a validity measure. Then this value is used as a limiting value in merge algorithm. The performance of algorithm is measured using a validity index which is measured by two factors. The first factor is intra-cluster distance whose minimum value is desired and another is inter-cluster distance for which a maximum value is required. Once optimum number of cluster is found then k-means clustering algorithm is again applied to generate large number of clusters, then from these large numbers of clusters, pair of clusters with most similar characteristics are merged iteratively until number of clusters are reduced up to optimum number of clusters. The similarity measure is taken from Davies-Bouldin Index. The proposed algorithm is performing better than simple k-means algorithm. Read More...

Fatigue Strength of High Strength Concrete under Cyclic Loading
-Vinodkrishna M Savadi ; Dr. S.S. Injaganeri
The interest in the fatigue of concrete began more than a hundred years ago with the development of reinforced concrete. The technological development in high strength concrete (HSC), has led to construction of modern complicated structures of considerable height and span. However, HSC is more brittle than conventional concrete, so, an alternative method to enhance ductility is to add fibers into the concrete matrix thus fiber reinforced concrete is made. Nowadays, the fatigue behavior of fiber reinforced concrete is getting more and more attention due to frequent application of cyclic loads as shown in figure 1. The aim of the present study is to investigate the fatigue strength of conventional HSC. The M60 grade concrete has been designed as per ACI-211.4-R based on trial mixes. Four concrete beams were cast of reinforced conventional HSC. All the beams have been tested under three point loading using 500 kN servo controlled actuator. The stress ratio in the range of 0.7-0.9 with an interval of 0.1 was incorporated for cyclic loading of beams. From the experimental data obtained, a relationship between S-N has been developed. An equation has been proposed to predict the fatigue strength of conventional (without fibers). Read More...

-Priyesh N. Santoki ; Prof. Ashwin P. Bhabhor
The correct selection of manufacturing conditions is one of the most important aspects to take into consideration in the majority of manufacturing processes and particularly, in processes related to Electrical Discharge Machining (EDM). Electrical Discharge Machining performance is generally evaluated on the basis of Overcut (OC), Material Removal Rate (MRR), Tool Wear Rate (TWR) and Surface Roughness (SR). The important EDM machining parameters affecting to the performance measures of the process are discharge current, pulse on time, pulse off time, arc gap, and duty cycle. Several approaches are proposed in the literature to solve the problems related with optimization of these parameters. It is felt that a review of the various approaches developed would help to compare their main features and their relative advantages or limitations to allow choose the most suitable approach for a particular application and also throw light on aspects that needs further attention. In view of above, this paper presents a review of Effect of Electrode Material on Overcut, MRR, TWR and Surface Roughness of AISI 304 Stainless Steel in EDM. Read More...

Survey on Incremental Association Rule Mining to find Frequent Itemsets
-suchi parekh ; Neha R. soni
Mining frequent Itemsets has proved to be very difficult because of its computational complexity. But, , it has gained a lot of popularity due to the usefulness of association rules, despite having huge processing cost. This paper provides a comprehensive survey on the state-of-art algorithms for association rule mining, specially when the datasets used for rule mining are dynamic. When new data are added to a original dataset it may lead to additional rules or to modification of some existing rules. To find the association rules from the whole (old as well as new) dataset will be wastage of time only if the process is restarted from the beginning. Several algorithms have been developed to attend this important issue of the association rule mining problem. This paper analyzes some of the algorithms to tackle the incremental association rule mining problem. Read More...

Experimental Investigations on Electroless Plating of Nickel on Steel
-Yagnesh B Chauhan ; Hardik B Patel
Electroless nickel plating on steel is carried out by a chemical reaction and without the use of an external source of electricity. In electroless nickel plating, nickel chloride will come as a metallic salt and is reduced by using Sodium hypophosphite as the reducing agent to nickel metal, which then is deposited on the steel. This process has now become an established industrial technique and gained increasing importanc. By such means not only pure metals but also alloys can be deposited on ferrous and non-ferrous materials to improve their surface characteristics. By using appropriate pee- plate treatment methods, a wide range of plastics and ceramics can also be plated by electroless methods. These processes have particular advantages in the field where galvanic processes can only be used at great expense or where they fail completely. The present paper studies the effect of different process parameters during electroless plating of nickel on steel. The effect of bath temperature, immerasion time and bath pH on plating thickness,and deposition rate has been recorded and presented in graphical form. Read More...
