Pattern Based Mining For Relevant Document Extraction

This paper presents efficient mining algorithm for discovering patterns from text collection and search for useful and interesting patterns. For extracting useful information we used pattern based model containing frequent sequential patterns and pruned the meaningless patterns. Here an innovative and effective technique is used for pattern discovery which includes SPM & FP growth algorithms for pattern mining and applies the processes of pattern deploying, pattern evolving, to improve the effectiveness of using and updating discovered patterns for finding relevant and interesting information

Role of universities in socio-economic development

A university is an institution of higher education and of research, which grants academic degrees. It also provides both tertiary and qnatemary education. University is derived from the Latin word universitas, meaning corporation, since the first "modem" (medieval European) universities were simply groups ofscholar

Comparative node selection-based localization technique for wireless sensor networks: A bilateration approach

Wireless sensor networks find extensive applications, such as environmental and smart city monitoring, structural health, and target location. To be useful, most sensor data must be localized. We propose a node localization technique based on bilateration comparison (BACL) for dense networks, which considers two reference nodes to determine the unknown position of a third node. The mirror positions resulted from bilateration are resolved by comparing their coordinates with the coordinates of the reference nodes. Additionally, we use network clustering to further refine the location of the nodes. We show that BACL has several advantages over Energy Aware Co-operative Localization (EACL) and Underwater Recursive Position Estimation (URPE): (1) BACL uses bilateration (needs only two reference nodes) instead of trilateration (that needs three reference nodes), (2) BACL needs reference (anchor) nodes only on the field periphery, and (3) BACL needs substantially less communication and computation. Through simulation, we show that BACL localization accuracy, as root mean square error, improves by 53% that of URPE and by 40% that of EACL. We also explore the BACL localization error when the anchor nodes are placed on one or multiple sides of a rectangular field, as a trade-off between localization accuracy and network deployment effort. Best accuracy is achieved using anchors on all field sides, but we show that localization refinement using node clustering and anchor nodes only on one side of the field has comparable localization accuracy with anchor nodes on two sides but without clustering

Stylo in India: Much More Than a Plant for the Revegetation of Wasteland

Since the 1950s introductions of Stylosanthes scabra, S. hamata and S. guianensis from Australia, South America, the USA and Africa have continued in India. Although no cultivar has been released, selections of S. scabra, S guianensis and S. hamata are used in a range of environmental and commercial production systems. A large seed industry spanning \u3e400 ha and run by \u3e600 smallholder farmers producing 800t seeds/ year supports this usage (Rao et al., 2004). Stylo is mainly used in India for revegetation of wastelands where it reduces soil erosion and offers fodder for livestock (Pathak et al., 2004). Relatively small use is made as supplementary feed for dairy and breeding farms, as pastures in sheep and goat farms, in urban forestry and as a cover crop in horticulture and agroforestry. There are probably some 20,000 ha under silvipasture and horticulture. In mixed crop-livestock farming system stylo has been a saviour for smallholder farmers in some arid areas. The recent success of S. seabrana as a multipurpose legume and the suitability of stylo leaf meal as a replacement for expensive constituents in commercial poultry feed formulations may further accelerate uptake

International Seminar on Policy Issues in Fisheries and Aquaculture

Indian fisheries sector plays an important role in socioeconomic development of the country in view of its potential contribution to national income, nutritional security, employment opportunities, social objectives, and export earnings. The fisheries sector has witnessed an impressive transformation from a traditional subsistence activity to a well developed, diversified commercial enterprise with vast untapped potential. Amidst this steady growth, there are issues of concern like the over exploitation of fisheries resources, sustainability, environmental degration, ecosystem management, provisions of WTO and pollution which necessiate the need for proper legislation and regulatory measures. It is in this context, policy interventions play a pivotal role in fisheries development. These assume greater significance in the wake of liberalization process presently on in the country. It is necessary to reorient and formulate the policies in fisheries sector to enhance the effectiveness of the sector and to compete at the global level

A Multiband Slot Antenna loaded with Stubs for WLAN/WiMAX/Satellite TV Applications

A compact planar multiband antenna operating at 2.65 (lower WiMAX)/5.20 (WLAN)/6.75/7.30 GHz (Satellite TV) is presented. The antenna consists of circular radiator in which a rectangular slot is etched out. Also, the circular radiator is loaded with a rectangular and two hook-shaped stubs to achieve multiband operations. The impedance matching at these bands is achieved by using two small square stubs placed inside the hook-shaped stubs. The antenna has an electrical dimension of 0.17λl x 0.17λl x 0.01λl at the lower frequency of 2.65 GHz. The antenna has S11<-10dB bandwidth of 3% (2.6-2.68GHz), 2.3% (5.12-5.24GHz), 1.2% (6.68-6.76GHz) and 1.37% (7.26-7.36GHz) in simulation and about 6.25% (2.48-2.64GHz), 2.24% (5.3-5.42GHz), 1.15% (6.92-7.00GHz) and 1.1% (8.04-8.12GHz) under measurement. The entire simulation analysis of the antenna is carried out using HFSS v.13.0

Biochemical basis of iron deficiency chlorosis resistance in groundnut (Arachis hypogaea L.)

A pot experiment with factorial design involving normal and calcareous soil and five genotypes with differential response to iron deficiency chlorosis (IDC) viz., ICGV 86031 and A30b (Resistant), TG 26 (moderately Resistant), TAG 24 and TMV 2 (susceptibe) were tested for various traits like VCR and SCMR, chlorophyll a, b and total chlorophyll, active iron content, specific activity of peroxidase at five different stages and also know the effect of IDC on yield and yield components. Iron deficiency chlorosis resistant genotypes recorded significantly lower VCR, higher SCMR, higher active iron content, chlorophyll a, b and total chlorophyll and peroxidase activity in leaf across all stages compared to susceptible genotypes. A strong and positive correlation was observed between peroxidase activity and leaf iron content. Yield and yield components were significantly reduced in susceptible genotypes compared to resistant genotypes
