Photo-sensitivity of large area physical vapor deposited mono and bilayer MoS2
Wang Baoming,Muratore Christopher,Voevodin Andrey A,Haque Md Amanul 나노기술연구협의회 2014 Nano Convergence Vol.1 No.22
We present photosensitivity in large area physical vapour deposited mono and bi-layer MoS 2 films. Photo-voltaic effect was observed in single layer MoS 2 without any apparent rectifying junctions, making device fabrication straightforward. For bi-layers, no such effect was present, suggesting strong size effect in light-matter interaction. The photo-voltaic effect was observed to highly direction dependent in the film plane, which suggests that the oblique deposition configuration plays a key role in developing the rectifying potential gradient. To the best of our knowledge, this is the first report of any large area and transfer free MoS 2 photo device with performance comparable to their exfoliated counterparts.
압바스 키아로스타미의 영화 스타일 분석 연구: 클로즈업, 내 친구의 집은 어디인가, 올리브 나무 사이로의 미장센 중심
송바오밍 ( Song Baoming ) 한국영화교육학회 2023 영화교육연구 Vol.17 No.3
압바스 키아로스타미는 '할리우드 대작'이 유행하는 시기에 그 독특한 영화 스타일로 인해 주목받았다. 그는 이란 국가의 영화 발전에 중요한 역할을 했고, 새로운 영화 스타일을 만들어냈으며, 전 세계 다른 나라의 영화에 좋은 모델을 제공했다. 이 논문은 그의 영화 스타일을 가장 잘 대변하는 작품들을 연구 대상으로 삼았다. 이 작품들은 클로즈업, 내 친구의 집은 어디인가, 그리고 올리브 나무 사이로를 포함한다. 이 글은 미장센에 관련된 다양한 요소를 중점적으로 분석할 것이며, 영상, 촬영, 조명, 음향, 공간, 장면 및 배우 등이 포함된다, 이를 이탈리아 네오리얼리즘 창작 원칙과 대조한다. 또한, 이 논문은 그의 영화의 주제와 방식을 논의하고, 압바스 키아로스타미의 전체적인 영화 스타일을 이해하며, 다수의 영화 연구자와 창작자에게 가치 있는 경험과 참고 자료를 제공한다. This article will delve deep into the film styles of three iconic works by Kiarostami, namely Close Up, Where Is the Friend's Home, and Through The Olive Trees. The analysis will primarily focus on elements related to Mise-en-scene, including visuals, cinematography, lighting, sound recording, space settings, and actors. In addition, while discussing the narrative themes and techniques of Kiarostami's films, it will also be compared with the principles of Italian neo-realism. The aim is to capture the overarching characteristics of Abbas Kiarostami's film style, offering valuable insights and inspiration for numerous film researchers and creators.
Fuzzy Detection on Color Image
Guo Liu,Baoming Bai,Gwanggil Jeon 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.2
This paper describes a new color image edge detection method. Edge detection application based on fuzzy set theory is introduced in this paper. First of all, we design fuzzy inference engine to detect image edges. In inference engine step, two Gaussian membership functions in two directions (horizontal and vertical) are used for input signals. Finally, two triangle and one Gaussian membership functions were used for defuzzification step. By using fuzzy process and defuzzification, we obtain a relationship between input and output values. Simulation results show the proposed method outperformed conventional edge detection methods.
Denoising Mapping Utilizing Constellation Symmetry in Denoise-and-Forward Two-Way Relay Channels
Jianping Zheng,Baoming Bai,Ying Li 한국전자통신연구원 2012 ETRI Journal Vol.34 No.4
The denoising mapping with the closest-neighbor clustering (CNC) method in denoise-and-forward two-way relay channels is studied. Specifically, the symmetry of the constellations in source terminals A and B is utilized to reduce the complexity of the CNC method. The specific case considered first to illustrate how the constellation symmetry works in the CNC method is the quadrature phase-shift keying constellation in A and B and the single-antenna deployment in all terminals. This case study shows that an enormous complexity reduction can be achieved. Next, the result is extended to multiple-antenna scenarios and square quadrature amplitude modulations.
Power Efficient Edge Sharpening
Guo Liu,Baoming Bai,Gwanggil Jeon 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.4
This paper studies power efficient image processing method for power consuming display device. Power is consumed by display device and its portion is large. We developed unsharp masking under power-constrained condition. For this system, we assume an image is dark with low contrast. The presented unsharp masking adopts high pass filter, Butterworth filter, and histogram equalization. Simulation results compare visual performance in several power-constrained conditions with factors of n. Results show that the proposed method achieved good visual quality and significant power saving performance.

In this letter, we consider the lossy coding of a non-uniform binary source based on GF(q)-quantized low-density generator matrix (LDGM) codes with check degree dc=2. By quantizing the GF(q) LDGM codeword, a non-uniform binary codeword can be obtained, which is suitable for direct quantization of the non-uniform binary source. Encoding is performed by reinforced belief propagation, a variant of belief propagation. Simulation results show that the performance of our method is quite close to the theoretic rate-distortion bounds. For example, when the GF(16)-LDGM code with a rate of 0.4 and block-length of 1,500 is used to compress the non-uniform binary source with probability of 1 being 0.23, the distortion is 0.091, which is very close to the optimal theoretical value of 0.074.
Clipping Value Estimate for Iterative Tree Search Detection
Jianping Zheng,Baoming Bai,Ying Li 한국통신학회 2010 Journal of communications and networks Vol.12 No.5
The clipping value, defined as the log-likelihood ratio (LLR) in the case wherein all the list of candidates have the same binary value, is investigated, and an effective method to estimate it is presented for iterative tree search detection. The basic principle behind the method is that the clipping value of a channel bit is equal to the LLR of the maximum probability of correct decision of the bit to the corresponding probability of erroneous decision. In conjunction with multilevel bit mappings, the clipping value can be calculated with the parameters of the number of transmit antennas,Nt; number of bits per constellation point, Mc; and variance of the channel noise, σ2, per real dimension in the Rayleigh fading channel. Analyses and simulations show that the bit error performance of the proposed method is better than that of the conventional fixed-value method.
