  • Storage and Computation on Big Data: A Comparative study

    CH Sravan Kumar, P. Buddha Reddy, K. Srinivas

    [ View:    Abstract ] [ HTML Full Text]

    A huge data space includes set of interesting points; Skyline is an important operation in many applications to return a set of interesting points from a potentially huge data space [1].This survey paper highlights the characteristics of big data and their challenges. This paper also discusses the tools and techniques of big data.  The existing algorithms like SaLSa, SSPL are novel computation algorithms. SaLSa exploits the idea of presorting the input data so as to effectively limit the number of tuples to be read and compared [2].SSPL utilizes sorted positional index lists which require low space overhead to reduce I/O cost significantly [1].SSPL consists of two phases. In phase 1, SSPL computes scan depth of the involved sorted positional index lists. During retrieving the lists in a round-robin fashion, SSPL performs pruning on any candidate positional index to discard the candidate whose corresponding tuple is not skyline result. Phase 1 ends when there is a candidate positional index seen in all of the involved lists. In phase 2, SSPL exploits the obtained candidate positional indexes to get skyline results by a selective and sequential scan on the table [1].

  • A Study on Usage of E-Commerce Through Cell Phones by College Students

    J. Tamizhkumaran.1, Ranjanmayee Sabar1, P. Manesh Kumar2 and P. Ramajayan3

    [ View:    Abstract ] [ HTML Full Text]

    A study was conducted among the veterinary college students to ascertain the usage pattern of e-commerce in mobile application. A total of 120 students were interviewed personally with a semi structured interview schedule designed for the study. The study revealed that majority of the respondent (85 %) preferred android based phones, the main purpose for e-commerce usage through cell phones were used for recharging cell phones (78.3 %), booking tickets (53.3%), paying the bills (35%), online shopping (28.3%), money transfer (05.8%) and hotel booking (5%). The major e-commerce activity was carried out using debit/ ATM cards (80%), internet banking (35%) and mobile banking (11.6 %). The popular apps preferred by the respondents were Paytm (71.6%), Red Bus (44.1%), Book My show (43.3%), Ticket New (39.1%) and Irctc (32.5%). It is clear from the study that college students are interested in e-commerce usage through mobile applications and in coming years the trend of e-commerce usage will surely take a turn around.

  • Operational Monitoring System OMS with WSN (Wireless Sensor Network), RFID, GPS and CCTV in Agriculture

    Rajesh Kadchha

    [ View:    Abstract ] [ HTML Full Text]

    This manuscript proposes an agricultural environment monitoring server system for monitoring information concerning an outdoors agricultural production environment utilizing Wireless Sensor Network (WSN) technology. The proposed agricultural server collects environmental, agricultural land, seeds and soil information on the outdoors through WSN-based environmental and soil sensors, collects snaps information through CCTVs, area information      through RFID and collects location information using GPS modules.  This collected information is converted into data and saved in to a database through the agricultural server consisting of a sensor manager, which manages information gathered from the WSN sensors, an image information manager, which manages image information collected from CCTVs, RFID and a GPS manager, which processes location information of the agricultural server system, and provides it to producers. In addition, a solar cell-based power supply is implemented for the server system so that it could be used in agricultural environments with insufficient power infrastructure. This agricultural server could even monitor the environmental information on the outdoors, and it could be look forward that the use of such a system could participate to increasing crop yields and improving quality in the agricultural field by supporting the decision making of crop producers through analysis of the collected information.

  • ICT tool – Development of Calculator for Design of Solar Dryer

    Prakash R. Kolhe and Pradip P. Kolhe

    [ View:    Abstract ] [ HTML Full Text]

    Henry David said “Men Have Become the Tools of Their Tools.” In this era all the developing technology begin from calculation influenced by the computer programming ICT-tool. Today energy is main problem, by utilizing sun light energy(solar energy) problem can be minimize. Sun drying is still the most common method used to preserve agricultural products in most tropical and subtropical countries. However, being unprotected from rain, wind-borne dirt and dust, infestation by insects, rodents and other animal, products may be seriously degraded to the extent that sometimes become inedible and the resulted loss of food quality in the dried products may have adverse economic effects on domestics and international markets. The conditions in tropical countries make the use of solar energy for drying food practically attractive and environmentally sound. Dryers have been developed and used to dry agricultural products in order to improve shelf life. Solar drying facilities are economical for small holders, especially under favourable meteorological conditions.

    This paper discuss to design to calculate design of solar dryer. In this different parameters are determined i.e Moisture removed, Water activity, Equilibrium Relative humidity, Total Heat Needed, Enthalpy, Average Drying rate, Drying time, Collector area, Length of air vent, Velocity required. The calculator was developed using C language Version 3.0 Turbo c++ copyright (c)1990, 1992 by Borland International was developed.
