Effect of planting density and training on plant health and seed quality of bell pepper (Capsicum annuum L.) under protected conditions

A study was conducted at the Department of Seed Science and Technology, Dr. Y. S. Parmar University of Horti-culture and Forestry, Nauni, Solan (H.P.), India during Kharif 2012 to evaluate the effects of the different planting densities and training systems on plant health (powdery mildew severity) and seed quality of bell pepper cv. Solan Bharpur under pro-tected conditions (polyhouse). Experiment was laid out in naturally ventilated polyhouse using three different planting densi-ties (S1 - 45×15 cm, S2 - 45×30 cm and S3 - 45×45 cm) and four training levels (T1 - single shoot, T2 - two shoots, T3 - three shoots and T4 - four shoots)with three replicates. The combination S2T2 (plants spaced at 45x30 cm and trained to two shoots) was found superior over all other treatments in terms of seed yields i.e. per plant and per hectare (18.00 g and 959.87 kg, respectively) and was at par with important quality characters. The treatment combination S3T1 (plant spaced at 45×45 cm and trained to single shoot) resulted in least powdery mildew severity (21.21 %) and performed best for seed qual-ity characters viz. 1000 seed weight, germination percentage, seedling length, seedling dry weight, seedling vigour index-I & II (6.32 g, 95.75%, 10.86 cm, 3.26 mg, 1039.77 and 312.34, respectively) but it gave lower seed yield and thus it is uneconomic. Therefore, planting density 45×30 cm in combination with two shoot training system can be recom-mended for commercial seed production of bell pepper under protected conditions

Tree species diversity, distribution and population structure in a tropical dry deciduous forests of Chhatisgarh, India

Tree species diversity, distribution and population structure of tropical forests of Bharnawapara wildlife sanctuary was investigated. The study analyzed the structure of a tropical dry deciduous forest in Chhatisgarh at different sites i.e. closed natural forest, open natural forest and plantation forests of teak. The study was conducted by laying 30 quadrats, each 10 m × 10 m in size at different sites. In total, 246 trees belonging to 28 species of 17 families were recorded from 0.3 ha sampling area. Density ranged between 520 to 990 trees ha-1 subsequently, basal area ranged between 21.50 to 47.30 m2 ha-1. The dominant tree species was Cleistanthus collinus with an importance value index (IVI) of 57.70. Other important species were Terminalia tometosa (IVI 47.10), Lagerstroemia parviflora (36.92), Diospyros melanoxylon (28.42) and Madhuca indica(26.03). The Shannon-Wiener index (H?) ranged between 0.19 to 3.35 and Simpson’s index (C) between 0.12 to 0.95 indicating high tree species diversity of tropical dry deciduous forests. It is evident from the study that natural forest has an edge over plantation forest in terms of species diversity, dominance and richness. Tree species diversity, distribution and population structure provide baseline information for conservation and management of tropical dry deciduous forests in India. Efforts are needed to conserve the natural forest for their diversity and existence. They can also be supplemented with plantation forests to lower the biotic pressure

Factors affecting people’s participation in joint forest management programmes in Kinnaur district of Himachal Pradesh, India

The present investigation examined the various factors affecting people's participation in the planning, implementation and maintenance of JFM programmes in the tribal distrct (Kinnaur) of Himachal Pradesh. In total, 10 factors were identified that influence people’s participation in Joint Forest Management (JFM) activities in the study area, which were independently affecting in all of three development blocks. District as a whole factors affecting in decreasing order were Lack of awareness about participatory forest management (66%), lack of co-ordination with forestry officials (64%), non availability of routine funds (56%), lack of training and visit programme (56%), clash between agriculture and JFM activities (54%), lack of emphasis on quick economic activities (49%), improper usufruct sharing (43%) etc. were some of major factors that influenced people’s participation. Policy and development emphasis on these factors, particularly taking into consideration the geography and need based activity in the various development blocks will increase the people’s participation in similar kind of projects

Review of channel assignment schemes in cellular systems

The purpose of this dissertation is to provide an overview of different channel assignment schemes and compare them in terms of performance, flexibility and complexibility. We first start by giving an overview of the channel assignment problem in a cellular environment and we discuss the general idea behind major channel allocation schemes.​Master of Science (Communications Engineering

An Iterative Hybrid Algorithm for Roots of Non-Linear Equations

Finding the roots of non-linear and transcendental equations is an important problem in engineering sciences. In general, such problems do not have an analytic solution; the researchers resort to numerical techniques for exploring. We design and implement a three-way hybrid algorithm that is a blend of the Newton–Raphson algorithm and a two-way blended algorithm (blend of two methods, Bisection and False Position). The hybrid algorithm is a new single pass iterative approach. The method takes advantage of the best in three algorithms in each iteration to estimate an approximate value closer to the root. We show that the new algorithm outperforms the Bisection, Regula Falsi, Newton–Raphson, quadrature based, undetermined coefficients based, and decomposition-based algorithms. The new hybrid root finding algorithm is guaranteed to converge. The experimental results and empirical evidence show that the complexity of the hybrid algorithm is far less than that of other algorithms. Several functions cited in the literature are used as benchmarks to compare and confirm the simplicity, efficiency, and performance of the proposed method

Blended Root Finding Algorithm Outperforms Bisection and Regula Falsi Algorithms

Finding the roots of an equation is a fundamental problem in various fields, including numerical computing, social and physical sciences. Numerical techniques are used when an analytic solution is not available. There is not a single algorithm that works best for every function. We designed and implemented a new algorithm that is a dynamic blend of the bisection and regula falsi algorithms. The implementation results validate that the new algorithm outperforms both bisection and regula falsi algorithms. It is also observed that the new algorithm outperforms the secant algorithm and the Newton–Raphson algorithm because the new algorithm requires fewer computational iterations and is guaranteed to find a root. The theoretical and empirical evidence shows that the average computational complexity of the new algorithm is considerably less than that of the classical algorithms
