Behaviour of Batter Micropiles Subjected to Vertical and Lateral Loading Conditions  [PDF]
Binu Sharma, Zakir Hussain
Journal of Geoscience and Environment Protection (GEP) , 2019, DOI: 10.4236/gep.2019.72014
Abstract: Micropiles are drilled and grouted piles having diameter between 100 to 250 mm. Due to its small diameter, it is suitable for low headroom and limited work area conditions. It can be installed without noise nuisance, without vibrations to surrounding soils and structures and without disruption to the production operations in industries which makes micropiles suitable for underpinning and seismic retrofitting of structures. It is necessary to therefore understand the behaviour of micropiles under different loading conditions. This work is on vertical and battered micropiles with different length/diameter ratio (L/D) subjected to vertical and lateral loading conditions. Batter angles had a significant influence on both the vertical and lateral load carrying capacity. The ultimate vertical load was found to increase upto a 30° batter. The ultimate lateral load was found to increase significantly with increasing L/D ratios upto an L/D ratio of 30 for vertical and 48 for battered piles, beyond which the increase was found to be not significant. In general, negative battered micropiles offered more lateral resistance than positive battered micropiles. The results of the study indicated that the ultimate load capacity and mode of failure of the micropiles are a function of the angle of batter, direction of batter and the L/D ratio for vertically and laterally loaded micropiles.
Use of GIS Based Maps for Preliminary Assessment of Subsoil of Guwahati City  [PDF]
Binu Sharma, Shaffi Kamal Rahman
Journal of Geoscience and Environment Protection (GEP) , 2016, DOI: 10.4236/gep.2016.45011
Abstract: Guwahati, the major city in the North Eastern region of India is growing rapidly in every aspect with major infrastructures like sports complex, educational institutions, hospitals, flyovers, multiplex halls, etc. Knowledge of the subsurface soil condition is necessary to ensure the structural safety and serviceability of the above mentioned structures before any construction. Therefore, contour maps of Standard penetration test N value, ground water table and shear wave velocity map using Geographical Information System (GIS) platform will be of great help to the foundation designers at the initial stage for site selection and preliminary foundation design under static and seismic condition. Contour maps of Standard penetration test N value at different depth and average contour map of N value of Guwahati city have been prepared. Standard penetration Test N values and depth of water table were taken from a data base of 200 boreholes up to 30 meter depth to prepare N value contour map of Guwahati city. A regression equation between shear wave velocity Vs and Standard penetration test N value based on twenty seven previous similar correlations was also developed. This regression equation was used to determine shear wave velocity of Guwahati city. The average shear wave velocities for 30 m depth for all locations had been determined and used to generate map on (GIS) platform. Other subsurface geotechnical information of Guwahati city like soil classification and depth to water level from ground surface is also presented in the form of GIS based maps in order to form a data base.
An Investigation into the Adhesion Strength of Diamond Like Carbon Multilayer Coating (DLC/TiN/Ti/Cu/Ni)  [PDF]
Intelligent Information Management (IIM) , 2009, DOI: 10.4236/iim.2009.13027
Abstract: Advancement in vacuum technologies and vapor deposition processes during last decades has led to the introduction of many modern coatings on metal cutting tools. Even in such an advanced vacuum coating techniques, the failure is not due to the wear of the coating but rather due to the lack of coating adhesion to the substrate. In this work, the coating adhesion test results were performed which is based on the Rockwell indentation tests. This coating adhesion tests were performed as per VDI standards 3198, 1991 for d.c. magnetron sputter deposition of diamond like carbon multilayer coating (DLC / TiN/ Ti / Cu / Ni) on tool substrate. Multilayer coating was deposited on tool substrates at different sputtering parameters/conditions such as power density, partial pressure, substrate temperature and reactive gases. The coated multilayer films were characterized by experimental techniques such as X-ray diffractometer which measures the material deposited, micro Raman spectroscopy and TEM to check DLC, Rockwell indentation to examine adhesion strength, optical profilometer to measure thickness of coating. Ni increases the Cu adhesion on tool substrate. Cu accommodates the shear stress induced by the films / substrate and the mismatch in thermal expansion coefficient, while Ti and TiN promote better DLC bonding. As the target power was increased the adhesion strength, micro hardness and deposition rate were observed to improve. Increase in target power and substrate temperature enhances adhesion strength. Proper substrate preparation and sequence of cleaning processes are the crucial factors for the enhancement of adhesion strength. The sputter deposition conditions for the above mentioned multilayer coatings are identified in this work to get improved quality with particular reference to adhesion and surface finish.
Evaluation of some promising sweet potato clones for early maturity
B. Vimala and Binu Hariprakash
Electronic Journal of Plant Breeding , 2011,
Abstract: Early maturity studies were carried out with 8 high yielding clones for 3 seasons. The harvesting was done at 75, 90 and 105 days after planting (DAP). At 75 days, the yield of three clones ranged from 12 - 14 t ha-1 and at 90 days, 20 – 26 t ha-1. At 105 days, only one clone had higher yield. Dry matter content analysis indicated that it varied from 24 – 32% and 28- 38 % at 75 and 90 days. At 105 days no significant difference was observed in the dry matter. However, in some clones it was less than at 90 days. The yield and dry matter analysis at the early growth stages helps to screen a large number of progenies and to identify high yielding clones in a breeding programe. Considering the above factors, it is worthwhile to harvest the storage roots of most cultivars at around 90-100 days after planting.
A Novel Web Classification Algorithm Using Fuzzy Weighted Association Rules
Binu Thomas,G. Raju
ISRN Artificial Intelligence , 2013, DOI: 10.1155/2013/316913
Abstract: In associative classification method, the rules generated from association rule mining are converted into classification rules. The concept of association rule mining can be extended in web mining environment to find associations between web pages visited together by the internet users in their browsing sessions. The weighted fuzzy association rule mining techniques are capable of finding natural associations between items by considering the significance of their presence in a transaction. The significance of an item in a transaction is usually referred as the weight of an item in the transaction and finding associations between such weighted items is called fuzzy weighted association rule mining. In this paper, we are presenting a novel web classification algorithm using the principles of fuzzy association rule mining to classify the web pages into different web categories, depending on the manner in which they appear in user sessions. The results are finally represented in the form of classification rules and these rules are compared with the result generated using famous Boolean Apriori association rule mining algorithm. 1. Introduction Classification is a Data Mining function that assigns items in a collection to target categories or classes. The goal of classification is to accurately predict the target class for each case in the data. For example, a classification model could be used to identify loan applicants in a bank as low, medium, or high credit risks. A classification task begins with a data set in which the class assignments are known. A classification model that predicts credit risk could be developed based on observed data for many loan applicants over a period of time. In addition to the historical credit rating, the data might track employment history, home ownership or rental, years of residence, number and type of investments, and so on. Credit rating would be the target, the other attributes would be the predictors, and the data for each customer would constitute a case. Classification techniques include decision trees, association rules, fuzzy systems, and neural networks. Classification has many applications in customer segmentation, business modeling, marketing, credit analysis, web mining and biomedical, and drug response modeling. Classification models include decision trees, Bayesian models, association rules, and neural nets. Although association rules have been predominantly used for data exploration and description, the interest in using them for prediction has rapidly increased in the Data Mining community. When

International Journal on Theoretical and Applied Research in Mechanical Engineering , 2013,
Abstract: Effect of heat treatment on A319 alloy with 0.45%wt Magnesium, 0.02%wt Strontium and grain refinement using Titanium has been investigated by hardness measurement and tensile testing. Experiments have been conducted at ageing temperatures 150°C, 160°C and 170°C. Hardness has been estimated up to 24 hours aged samples. The results indicate that hardness of 319 alloy increases with Sr addition and grain refinement. When Mg is added hardness is again found to be increasing progressively up to a maximum value and then varying non – uniformly. The tensile strength and microstructure after Mg modification and heat treatment have been discussed.
