(Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2013-01) Asadujjaman, M.; Shelly, N. J.; Islam, M. A.; Hossain, M. A.
A study on proximate composition of conventional and non-conventional fish feed ingredients was carried out involving two separate experiments. First experiment was conducted from April 2010 to September 2010 at the Protein and Enzyme Research Laboratory, Department of Biochemistry and Molecular Biology, Rajshahi University, Rajshahi with a view to determine nutrient (protein, lipid and carbohydrate) content of some feed ingredients i.e. Rice bran, wheat bran, mustard oil cake, Azolla, grass (Cynodon dactylon) and leaf of banana (Musa acuminate) among the feed samples, protein, lipid and carbohydrate content significantly varied from 6.18±0.13 (banana leaf) to 30.53±0.40% (oil cake), 3.06±0.09 (banana leaf) to 13.33±0.10% (oil cake) and 32.95±0.29 (oil cake) to 66.12±0.47% (wheat bran), respectively. Second experiment was conducted during the period from April 20 II to September 20 II at Alampur village of SOOarUpazila under Kushtia district, Bangladesh with a view to evaluate the fish production and economics under different conventional and non-conventional feed based carp polyculture systems. There were three replications for each treatment. In this experiment, treatment To(Semi-intensive ponds fed with feeds like rice bran, wheat bran and oi1cake as control) varied more significantly (P<0.05) for the mean values of total yield but in terms of total cost, total return, net benefit, net profit margin and eBR treatment T, (Azolla fed pond) was best. Therefore, the findings indicate that weeds (non-conventional feed items) are moderately nutritive and low cost effective diets for fish production.

(IEEE, 2016-10-28) Islam, M. A.
Speaker identification is a biometric technique of determining an unknown speaker's identity among a number of speakers using distinguish latent information of uttered speech. Crime investigation, security control, telephone banking and trading, and information reservation are some applications of this technique. Frequency Domain Linear Prediction (FDLP) is a time-frequency-based feature has been derived using 2-D autoregressive model. This feature was constructed from sub-bands short frame energies estimation. FDLP has been used in this study to propose a robust text-dependent speaker identification technique. The clean features were used to obtain speaker behavioural model. Support vector machine has been used to train the proposed method. This presented study was tested in both clean and noisy conditions to validate the method extensively. The proposed method got significant improved performance over all traditional methods performances in noisy conditions. The obtained performance was indicated; the proposed method was very robust to noises and showed consistent performance irrespective to noises.

(IEEE, 2016-10-28) Islam, M. A.
Gender classification technique is a part of the signal processing comprises with feature extraction and behavioural gender modelling. Fundamental frequency and pitch are mostly used as feature for gender detection due to their unique characteristics in voice source. In this study, Gammatone Frequency Cepstral Coefficient (GFCC)-based robust gender classification method has been presented. This study was accomplished using speech samples from a text-dependent data set. The prototype gender behavioural modelling was done using Gaussian mixture model (GMM) to obtain better performance and only clean signal was used to train the model. The performance of the proposed method was tested under both clean and contaminated conditions. The clean signal was contaminated using nine different noises at a range of signal-to-noise ratios (SNRs) from 0 dB to 10 dB. The obtained performance showed the proposed method was very robust against noise and the average performance at 0 dB SNR was almost 100% for female and 92% for male irrespective to noises. So, it could be said the proposed method performance was almost noise invariant.

The poultry sector continues to grow and industrialize in many parts of the world. The study was undertaken to analyze the marketing system of commer cially produced eggs, estimate cost and margin of egg traders in some selected areas of Mymensingh district in Bangladesh in 2018. Sixty (60) respondents were selected as total sample size where 19 were layer farm owner and 48 were egg traders. Two Upazila of Mymensingh district (Mymensingh Sadar and Trishal) were selected based on the production concentration and marketing. Two villages from each Upazila were selected for survey and data were collect ed from the traders for the study. Five different channels were identified accord ing to present egg marketing system. The average gross return of bepari, whole saler and retailer for 100 eggs are found Tk. 26.67, Tk. 31.82 and Tk. 37.14, respectively. The average cost of bepari, wholesaler and retailer for 100 eggs were found Tk.11.41, Tk.13.54 and Tk.15.78, respectively. The net margin of 100 eggs were calculated and found Tk.15.26, Tk. 18.28 and Tk. 21.37 respec tively for bepari, wholesaler and retailer. The producer share was higher i.e. 86.56% and price spread was lower (Tk. 85.84) in channel IV. In case of effi ciency channel IV was more efficient than other channels. Results suggested that, development of this enterprise is helpful in employment generation and poverty alleviation. The outcomes of this study may contribute to accurate and reliable data and other necessary information from the field level and future egg marketing system of various regions in Bangladesh.

A study was undertaken to evaluate the efficacy of plant extracts to control Bipolaris leaf blight (Bipolaris sorokiniana) and increasing grain yield of wheat. Water extracts of neem (Azadirachta indica). 'allamanda'(Allamallda cathartica), 'mehedi'(Lawsonia alba) leaves, 'bishkatali' (Polygonum hydropiper) shoot, 'garlic'(Allium sativum) clove, onion (Allium cepa) bulb, black cumin (Nigella sativa) seed, and ginger (Zingiber officinalis) rhizome were prepared at a concentration of I :2. Wheat seeds were treated with individual plant extracts. Seeds were also treated with Vitavax-200 for comparison. It was found that all the plant extracts except mehedi increased seed germination on blotter. A remarkable reduction in incidence of seed borne Bipolaris sorokiniana was achieved with the botanicals. The disease severity was the lowest under Vitavax-200, followed by bishkatali and garlic extract. The highest disease severity was recorded under control. The increasd grain yield over control was achieved with extracts of onion, garlic, black cumin, ginger, bishkatali and neem. The efficacy of plant extracts to decrease disease severity and to increase zrain vield was more or less similar to that of Vitavax -200.
Selection and Pathways to Next Generation Innovations of Speed Over Ground (SOG) Measurement Technologies to Overcome Harsh Conditions and Technological Limitations: A Review
(IEEE, 2024-09-15) Imam, Jakaria Mahdi; Mokhtar, N.; Hatta, S. F. W. Muhamad; Rashdan, Mostafa; Salman, Mohammad; Khandaker, Mayeen Uddin; Islam, M. A.
Determining speed over ground (SOG) with high precision is a critical challenge for marine and aerial vehicles due to various harsh conditions and technological limitations. Here, we review and evaluate current SOG measurement technologies, such as water speed sensor, air speed sensor, global navigation satellite system (GNSS), underwater acoustic positioning system (UAPS), Doppler velocity log (DVL), Doppler navigation system (DNS), simultaneous localization and mapping (SLAM), conventional inertial navigation system (INS), and their performance amidst harsh condition and technological limitations. It reveals the vulnerabilities, and noting their limitations when faced with stressors and technological challenges, thus highlighting the urgent need for resilient and innovative SOG measurement solutions. A substantial focus is placed on emerging sensor technologies, including cold atom inertial sensor (CAIS), micro-opto-electro-mechanical systems (MOEMS) inertial sensor, and particle imaging velocimetry (PIV) inertial sensor. Each of them presents a new frontier in navigational sciences, offering the potential for improved precision and robustness against harsh conditions that traditionally hamper SOG measurement accuracy. However, they still suffer from technological limitations like integration error over time. The Galilean projectile model-based SOG Sensor is spotlighted for its potential to provide a contactless, environment-independent SOG measurement, which is less prone to both harsh conditions and technological limitations like integration error over time. As such, this article outlines a pathway toward selecting the best SOG sensor based on harsh conditions and technological limitations for particular applications, as well as future research direction that could significantly enhance the reliability and accuracy of SOG measurements, ensuring safer and efficient navigation
