Human Bond Communication with Head-Mounted Displays: Scope, Challenges, Solutions, and Applications
Hossan, Md. Tanvir,Chowdhury, Mostafa Zaman,Shahjalal, Md.,Jang, Yeong Min Institute of Electrical and Electronics Engineers 2019 IEEE communications magazine Vol.57 No.2
<P>In this article, we introduce a human bond communication (HBC) method, based on head-mounted displays (HMDs), which enables continuous bidirectional communication among multiple users with or without Internet connections. The disadvantages of the existing technologies limit the scope of this study to provide a communication platform for HMD-based HBC. However, the features of the optical camera communication (OCC) technology will enrich the possibilities of HBC. This leads us to introduce a visual communication approach for virtual applications. To deploy OCC in HMDs for HBC, the camera of an HMD can be used as a receiver, while a near-infrared light source must be added to the HMD as a transmitter. We also discuss some potential future applications, suggest effective architectures, and briefly describe the scope, challenges, and solutions of OCC-based HMDs for HBC.</P>

The influence of supplementing diets with various levels of organic zinc (OZ) on the performance, meat quality attributes, and sensory properties of broiler chickens was investigated. A total of 3,200 1-d-old female broiler chicks were randomly allotted to 16 floor pens (replicates) with 200 birds per pen. A corn-wheat-soybean meal basal diet (control) was formulated and 20 ppm OZ (20 OZ), 40 ppm OZ (40 OZ), or 80 ppm OZ (80 OZ) was added to the basal diet to form four dietary treatments with four replicates per treatment. Live performance of broiler chickens, meat quality, and sensory properties were valuated. The results showed no significant difference among the treatments for live performance of broiler chickens. Significant increases (p
A Novel Indoor Mobile Localization System Based on Optical Camera Communication
Hossan, Md. Tanvir,Chowdhury, Mostafa Zaman,Islam, Amirul,Jang, Yeong Min WILEY INTERSCIENCE 2018 WIRELESS COMMUNICATIONS AND MOBILE COMPUTING Vol.2018 No.-
<P>Localizing smartphones in indoor environments offers excellent opportunities for e-commence. In this paper, we propose a localization technique for smartphones in indoor environments. This technique can calculate the coordinates of a smartphone using existing illumination infrastructure with light-emitting diodes (LEDs). The system can locate smartphones without further modification of the existing LED light infrastructure. Smartphones do not have fixed position and they may move frequently anywhere in an environment. Our algorithm uses multiple (i.e., more than two) LED lights simultaneously. The smartphone gets the LED-IDs from the LED lights that are within the field of view (FOV) of the smartphone’s camera. These LED-IDs contain the coordinate information (e.g., <TEX>$ x$</TEX> - and <TEX>$ y$</TEX> -coordinate) of the LED lights. Concurrently, the pixel area on the image sensor (IS) of projected image changes with the relative motion between the smartphone and each LED light which allows the algorithm to calculate the distance from the smartphone to that LED. At the end of this paper, we present simulated results for predicting the next possible location of the smartphone using Kalman filter to minimize the time delay for coordinate calculation. These simulated results demonstrate that the position resolution can be maintained within 10 cm.</P>

본 연구에서는 다카(Dhaka) 주식시장의 경우를 활용하여 수익률기반의 매매전략에 대해 알아보고 있다. 모멘텀(momentum)과 콘트래리온(contrarian)이라 불리는 수익률기반의 매매전략 중에서 모맨텀 투주전략이 더 나은 성과를 가져다준다는 사실을 알아내었다. 지난 36개월간의 수익률을 기반으로 60일간 보유하는 전략이 가장 높은 수익률을 가져다주고 있다. 장기적인 가격 역전현상 또한 발견할 수 있었다. This paper investigates performances of return based trading strategies in Dhaka Stock Exchange (DSE) of Bangladesh. Of the two return based trading strategies named momentum and contrarian strategy, this paper finds momentum strategies are more profitable than contrarian strategy in DSE. Forming momentum strategy based on previous thirty six months' return and holding it for the next thirty six month is found most profitable in this study. Long - run price reversal is also found in this study.

Live performance of broiler chickens, meat quality, and sensory properties were evaluated. The results showed no significant difference among the treatments for live performance of broiler chickens. Significant increases (p<0.05) in thigh skin epidermis and dermis thickness were shown in the OZ supplementation groups;however, no effect of OZ on the thickness of back skin epidermis or dermis was found. Dietary OZ levels did not affect the pH of breast and thigh meat or the water holding capacity (WHC) of thigh meat, but the WHC of breast meat increased significantly (p<0.05) when birds were fed 40 OZ and 80 OZ. Results of a sensory analysis showed no differences among the dietary treatments. In conclusion, dietary OZ did not affect live performance or sensory properties of broiler chickens but did increase the WHC of breast meat and thickness of skin layers; thus, improving carcass quality in broiler chickens.

Efficiency of Operating Lease Financing in Airlines Business : A DEA Study
Mohammad Akter Hossan,Park Sang Bum 한국재무학회 2007 한국재무학회 학술대회 Vol.2007 No.04
Airline companies’ uses different type of lease financing like capital lease, operating lease, and sale – and – lease back type lease. Out of them it is found in some earlier researches that sale – and – lease back type lease has influence on share prices. In this paper operating lease has taken under consideration for same purpose and used as input for output oriented DEA model in order to measure relative efficiency of using lease over time for airline companies, to determine benchmark and finally to find out where improvement is essential to be efficient. Here outputs are selected for DEA model based on previous researches where researchers mentioned some benefits of using lease. The result of DEA is found in this study that some companies are handling operating lease efficiently compare to others. Based on this efficiency scores sample companies are grouped and Mann Whitney rank sum test was applied to observe whether efficiency has any influence on share price increase in capital market or not. It is found here that operating lease does not have this kind of influence or impact on market price of shares.
