BanglaMusicStylo: A Stylometric Dataset of Bangla Music Lyrics


Abstract:
With the rapid growth of Bangla music industry huge volume of Bangla songs are produced every day. Immense number of producers, lyricists, singers and artists are involved in production of songs from different genres. Among many genres of Bangla music; classical, folk, baul, modern music, Rabindra Sangeet, Nazrul Geeti, film music, rock music and fusion music has gained the highest popularity. Lyricists try to express their feelings and views towards any situation or subject through their writings. Therefore, each lyricist have their own dictionary of thoughts to put on music lyrics. In this paper, we have presented “BanglaMusicStylo”, the very first stylometric dataset of Bangla music lyrics. We have collected 2824 Bangla song lyrics of 211 lyricists in a digital form. All the lyrics are stored in text format for further use. This dataset could be used for stylometric analysis such as authorship attribution, linguistic forensics, gender identification from textual data, Bangla music genre classification, vandalism detection, emotion classification etc. Identifying the significant research opportunities in this area, we have formalized this dataset which could be used for stylometric analysis.

Cooperative Spectrum Prescience for Advanced Performance of Cognitive Radio Networks (CRNs)

Abstract:
In this paper, the spectrum and energy efficiency (EE) of cooperative spectrum prescience (CSP) in cognitive radio networks (CRNs) are investigated. In integration, the performance of CSP is evaluated utilizing hidden Markov model (HMM) and a multilayer perceptron (MLP) neural network. The cooperation between secondary users in presaging the next channel status employs AND, OR and majority rule fusion schemes. Simulation results show a paramount rule in the spectrum efficiency utilizing CSP with the majority rule at the cost of a diminutive degradation in energy efficiency compared to single spectrum prescience (SSP) and traditional spectrum sensing (TSS). The HMM prognosticator provides better performance than the MLP presage. Moreover, the total probability of prescience error with the majority rule provides the best performance compared to SSP and the other fusion rules. On the other hand, the AND and OR rules have the worst performance in the high and low traffic cases, respectively. The majority rule provides a good tradeoff between diligent and redundant state prescience errors compared with the AND and OR rules and SSP. Further, a reduction in the diligent state prescience error increases the spectrum efficiency (SE) more compared to a reduction in the redundant state prescience error.

Design and analysis of slotted core photonic crystal fiber for gas sensing application

Abstract
In this paper, a slotted core photonic crystal fiber (PCF) has been designed. A rigorous numerical investigation has been done over the wider range of the wavelength from 1.30 µm to 2.0 µm near inferred region (IR). By employing full vectorial finite element method (FV-FEM) having completely circular anisotropic perfectly matched layer (C-PML) different optical parameter such as nonlinearity, confinement loss, sensitivity, beat length, V-parameter and splice loss of the modeled PCF have been uncovered. The investigated upshot testifies that the birefringence gained at the order of 10−2. Nevertheless, the proposed fiber experienced with the lower order (1.26 × 10−5 dB/m) of confinement loss with a higher order of nonlinearity 54.33 W−1 km−1 at simultaneously at the operating optical wavelength λ = 1.33 µm. Moreover, the impacts of the geometric parameters have been turned on birefringence, nonlinearity and confinement losses which are also analyzed in detail. The proposed PCF model with investigated results provides stronger evidence that, the structure will play a substantial role in the area of optical waveguides as well as optical devices or instrumentations.

Highly birefringent, low loss single-mode porous fiber for THz wave guidance

Abstract
In this letter, authors have proposed a circular structured photonic crystal fiber for low-loss terahertz waveguiding. Transmission characteristics of the photonic crystal fiber (PCF) have been conducted by implementing a perfectly matched layer (PML) in the boundary using finite element method. Power transmitted through the core has been improved by tuning the geometries of the core air holes. The proposed design at the porosity of 80% and a diameter of 304 µm has reported a very low effective material loss of 0.046 cm−1. In the meantime, it reduces the maximum bulk absorption material loss by ∼77%. Moreover, the utmost birefringence of 0.057 is derived at the frequency f = 1.01 THz. Properties like, power fraction of the core air holes, responses of the effective material loss on the basis of the geometric parameter, power fraction with respect to diameter, have been also reported and well discussed.

Effect of the bandgap, sun concentration and surface recombination velocity on the performance of a
III-V bismide multijunction solar cells


Abstract

In this paper, an emerging material GaAs1-xBix has been introduced in different layers of multijunction solar cells. By modifying the spectral p-n junction model, the theoretical efficiencies of two-, three- and four-junction III-V bismide multijunction solar cells have been estimated to be 36.5%, 44.0%, and 52.2% respectively for AM1.5G under 1 sun condition. The effects of the material bandgap, sun concentration, and surface recombination velocity on the solar cell have been studied extensively. Simulation results revealed that an increment up to ~10% on the overall cell efficiency can be achieved by concentrating the solar radiation from 1 sun to 500 sun; and a 3 – 4 % increment on the overall cell efficiency by tuning the bandgap of the bismide layer as well as modeling the surface recombination velocity involved.  Simulation results could be utilized for better understanding the materials as well as in realization of highly efficient bismide based multijunction solar cells.

Silicon nano crystal filled ellipse core based quasi photonic crystal fiber with birefringence and very high nonlinearity

Abstract
In this paper, we have proposed a new type of quasi photonic crystal fiber (PCF) with a silicon nano crystal core. This structure can be used to sense aqueous analysis over a wavelength range of 1.00 µm to 3.00 µm. The properties of this structure are simulated using the vector-finite element method (VFEM) employing a boundary condition. The proposed model provides a significant effect of birefringence and a very high nonlinear coefficient for two different fundamental modes, which are obtained by adjusting the size of the silicon nano crystal filled ellipse core. This provides a high nonlinearity of 4.2 × 105 W−1Km−1 and a birefringence of ̴ 3.2 × 10−1 at the wavelengths 1.00 µm and 3.00 µm, respectively. Some others properties, such as the effective area, scattering loss, confinement loss, numerical aperture (NA)and power fraction are also analyzed to measure the performance of this structure. The proposed model is useful for sensing and biomedical imaging applications. The proposed structure may also find extensive applications in optical communication and sensor systems.

Low material loss and dispersion flattened fiber for single mode THz-wave transmission applications

Abstract
In the article, a very low loss terahertz (THz) photonic crystal fiber (PCF) has been proposed and investigated precisely. The investigation results have proved that the designed PCF shows very low effective material loss (EML) of 0.03 cm−1 at 1.0 THz that simultaneously indicates about 85% reduction of bulk absorption loss of the hosting material. Moreover, other optical parameters of the PCF such as effective mode area (EMA), confinement loss (CL), dispersion, V-parameter and figure of merit (FOM) have been investigated also. The proposed PCF testifies a flatted dispersion developed from 0.96 THz to 1.10 THz. The investigated outcomes indicate that the proposed PCF will be a good candidate for THz or T-ray transmission as well as in the area of photonics devices also.

Prediction of whiteness index of cotton using bleaching process variables by fuzzy inference system

Abstract
A fuzzy prediction model has been built based on hydrogen peroxide concentration, temperature and time of bleaching as the input variables and knitted fabric whiteness index as the output variable. The process parameters affecting the whiteness index of cotton knitted fabrics are very non-linear. Fuzzy inference system is a prospective modeling tool as it can map effectively in nonlinear domain with minimum investigational data. Triangular-shaped membership functions were considered for the variables and total 48 rules were created in this study. It was found that the sole effect of the concentration of hydrogen peroxide on whiteness is pretty low, but is affected by temperature noticeably even in a fixed concentration of hydrogen peroxide. The model proposed in the present study has been verified by additional experimental data set. The root mean square, mean absolute error percentage and coefficient of determination (R 2 ) between the predicted and experimental values were found to be 0.536, 0.798 and 0.959 respectively. The results validate that the model can be applied suitably for the prediction of fabric whiteness index in textile industries.

Geographical Indications in Bangladesh Supply Chain: What Needs to Be Done Now?

Abstract

Each country has its own standards to live up to. Geographical Indications is a type of Intellectual Property that recognize products to bear a certain reputation for themselves based on the country of its origin. It is logical to assume that they contain characteristics, like their quality, that are dependent on factors such as environmental or human characteristics. The role of Geographical Indications is vital in Intellectual Property and is gaining recognition rightfully. Bangladesh supply chain also enacted this act recently and is in the process of registering its traditional and specialized products. The present paper takes a synopsis of the existing scenario of Geographical Indications in Bangladesh supply chain. The paper will also show some strategies and roadmap from marketing perspectives to be taken by the authorities to reach and meeting the needs of the target customers of this particular sector. Two research methods, Case Study and In-depth Interviews have been used to collect primary data. A necessary aspect of this paper is how it sheds light on aspects that are needed to benefit from stimulating areas of GI and its proper application. Another vital discussion is regarding the increase in activities required to improve the marketing scheme of GI application. Enhancing quality is key to improving the products and the market. To secure the position of GI and their beneficiaries in Bangladesh supply chain, it is necessary that the Ministry if Industries works in collaboration and harmony with them.
