PERFORMANCE EVALUATION OF MUTUAL FUND IN INDIA FOR THE PAST 6 YEARS (2004-09)

Numerous studies have been conducted in the past involving performance evaluation of mutual fund. All these past researches have examined whether mutual fund can beat the market or not and had concluded that mutual fund generally do not outperform the market. This in turn had concluded that markets are efficient and there is no scope for abnormal profits. This research is carried out with the same intentions to investigate whether Mutual fund can beat the market or not. Therefore performance of 21 growth funds are analyzed for the past 6 years from April 2004 to March 2009,which is then compared to BSE-500.Performance of these sample funds are evaluated using different models such as Sharpe ratio, Jensen alpha, Treynor ratio, Information ratio and M-square. The analysis showed that 20 out of 21 funds had been able to outperform the market (BSE-500).This further had concluded that Indian markets are not that efficient

Photonic Sensor

Sustained efforts have been made at CSIR-CSIO over the last several years in the area of Fiber optics based research activities resulting in infrastructure development, expertise generation and fabrication of sensors & devices. These activities include optical fiber light guide technology, fiber optic components, assemblies and instruments, optical fiber measurement and characterisation benches, fiber optic sensors, application specific fiber optic systems, fiber Bragg gratings (FBGs)& long period gratings (LPGs) writing technology and associated sensors. Work has also been carried out in other related areas such as: holographic optical elements (HOEs), holographic nondestructive testing (HNDT) for defect diagnosis and restoration of precious art & cultural objects,display holography for exhibition of precious and culturally valuable objects, machine readable security holograms and holo phase mask for FBG writing. Details of the achievements made,infrastructural facilities established and current & future R & D programmes taken up in the area of Photonics are described here

An auto-layering model for the granulation of iron ore fines

An auto-layering mechanism for the granulation of iron ore fines and similar materials is proposed. It is phenomenologically consistent in the sense that large particles are explicitly excluded from depositing in relatively thin layers around the nuclei. Given appropriate inputs, such as the feed size distribution and the moisture-layer thickness relationship, the model is capable of calculating size distributions of granules and of their constituent particles, as well as partition coefficients which classify feed particles into nuclei or layering material. In addition, the model elucidates and reconciles the controversial role of intermediate size particles in the granulation process. The model is implemented by a novel sequential size interval-by-size interval calculation scheme that is tailored for its structure. The theoretical results are in reasonable agreement with published data

Theoretical and Experimental Study of Long-Period Grating Refractive Index Sensor

This article presents the theoretical and experimental investigation of the response of long-period gratings as a refractive index sensor. Cladding modes are calculated, and results are compared with Optigrating 4.2.2 (Optiwave Systems Inc., Ottawa, Canada). The response has been checked for refractive indices ranging from 1 to 1.458. Theoretically simulated results are in accordance with the experimental results. It was found that the software package calculated values correctly up to the seventh decimal point. The ambient refractive index response of a long-period grating over a much wider index range has been modeled for values both less and more than the cladding refractive index

Humidity Sensing Using Gelatin and Cobalt Chloride Coating on Indium Tin Oxide-Coated Long-Period Grating

In this article, humidity sensing using gelatin and cobalt chloride on indium tin oxide coated long-period gratings was proposed and demonstrated. First, a thin overlay of indium tin oxide was deposited on a long-period grating by using a simple dip coating methodology. Similarly, a combination of gelatin and cobalt chloride was deposited onto the indium tin oxide layer. A field emission scanning electron microscope provided detailed evidence of the attachment of amalgamation on long-period gratings. The designed sensor showed a significant shift in the resonance wavelength when the relative humidity varied from 40% to 95%, with a sensitivity of 0.12 nm/% relative humidity and an accuracy of 98.45%

Optimization of spray parameters in the fabrication of SnO2 layers using electrostatic assisted deposition technique

Tin oxide (SnO2) thin films for gas sensing applications were prepared using electrostatic spray deposition method under optimum deposition conditions. It is shown in the paper that desired film morphology can be obtained by controlling different spray parameters (liquid properties, applied voltage, nozzle-substrate distance and substrate temperature). The spray parameters were optimized with respect to droplet diameter and applied voltage. An empirical relationship between critical voltage and different spray parameters was established for optimization. The morphology of the films prepared using these optimized spray parameters were investigated using X-Ray Diffraction (XRD) and Scanning Electron Microscope SEM)

Modelling and Estimation of Spatiotemporal Surface Dynamics applied to a Middle Himalayan Region

Accurate and timely estimation of the spatiotemporal surface dynamics is very important for natural resource planning and disaster mitigation. This paper discusses a novel technique to assess the patterns of the surfaces of a particular severe landslide susceptible zone (Kullu-Larji-Rampur geological window, near Aut village, district Mandi, Himachal Pradesh, India; N 31°44’34.78’’ E 77°12’29.02’’). The spatiotemporal surface dynamics of this region, spanning over last 20 years (1989 - 2009), has been modelled using Landsat TM images acquired during summers of 1989, 2000 and 2009. The proposed technique uses image processing to derive regression models of selected area segments, these models are then used to measure area under the curve to estimate the surface area changes. The surface area changes thus obtained have also been validated by standard method of pixel counting. Principal component analysis has been done in order to understand the correlations amongst the estimated parameters, namely; segment lengths, percentage area change and the area change in the first (1989-2000) and second (2000-2009) decades. The results obtained show a fair degree of accuracy as compared to the standard method of pixel counting
