Recently, how to make surveillance cameras running in all weather conditions become a very important research topic. Because surveillance images are often influenced by the weather conditions in a real world. In this paper, a fast single image fog removal algorithm based on an improved dark channel prior method is proposed. Compared to the latest works, the proposed algorithm can increase 28.5% computing speed and 41.8% image contrast ratio. Meanwhile, it can remove fog efficiently without the influence in the night too. © 2016 IEEE.

This study takes an electronic company as example to enhance its supply chain management by applying concepts and guidelines from Supply Chain Council (SCC) as well as business intelligence tools. The company's Supplier Performance Management System (SPMS) was first examined by in-depth interviews with its users under the framework of Information Systems Success Model. Data collected through the interviews was under principles of case study research methods, and then was analyzed by Formal Concept Analysis (FCA) to get systematic, organized and insightful results. Based on these results, the SPMS was modified. The appropriateness of the Information System Success Model as well as system improvement was well validated. © 2011 ACADEMY PUBLISHER.

In this study, High Impedance Surface (HIS) structures are used to reduce the interaction between a wireless antenna and its user. Especially, T-Slot HIS structure is designed for 1.8-GHz-band wireless products. The performance of HIS is investigated by the reflection phase method. The new test method is also proposed to verify the performance of HIS by using Arch method. In the experiment, the high performance of T-Slot HIS added monopole antenna and other electromagnetic protective sheets is evaluated and verified in view of radiation pattern, Total Radiated Power (TRP), and Specific Absorption Rate (SAR). © 2013 IEEE.

This paper presents a novel adaptable 4-moduli set {2n+k, 2 n+1, 2n - 1, 22n+1}. It offers diverse dynamic ranges (DRs) from 25n - 2n to 25n+k - 2 n+k that are used to conquer the over-range issue in RNSapplication hardware designs. The proposed adaptable set possesses the coarse parameter n and fine parameter k. It not only has better parallelism and larger dynamic range (DR) than the existing adaptive 3-moduli sets, but also holds more sizable and flexible than the general 4-moduli sets with single parameter. For the adaptable R-to-B conversion, this paper first derives a fast reverse converting algorithm based on Chinese Remainder Theorem (CRT) and then presents the efficient converter architecture. From the experimental results, the proposed adaptable converter achieves better hardware performance in various DRs. Based on TSMC 0.18 μm CMOS technology, the proposed converter design is implemented and its results get at least 20.93% saving of Area-Delay-Power (ADP) products on average when comparing with the latest converter works.
