        Fawad Khan,Jayanta Kumar Basak,Mustafa Jaihuni,이덕현,이준현,김현태 한국농업기계학회 2020 바이오시스템공학 Vol.45 No.2

        Purpose In previous studies, the stability and maturity of forced aerated composts were examined from the physicochemical analysis inside the reactors. The objective of this study is to check the maturity and effects of forced aerated composts after its addition to soil and plants. Methods The composts were prepared from fresh chicken manure and sawdust in cylindrical reactors and aerated at 0.75, 0.50, and 0.25 L min−1 kg−1 organic matter (OM) for 1 month. Afterward, it was mixed with soil and coded as treatment T1 (0.75 L min−1 kg−1 OM aeration rate + soil), T2 (0.50 L min−1 kg−1 OM aeration rate + soil), T3 (0.25 L min−1 kg−1 OM aeration rate + soil), and CS (only soil), respectively. The soil properties (pH, electrical conductivity (EC), organic matter content (OM), loss of organic matter content, bulk density (BD), water holding(WH)) and plant growth (shoot length (cm), leaves’ area (cm2), fresh and dry weight (g)) were checked for 4 months. Results The results showed a significant increase (at P < 0.05) in soil properties in T1, T2, and T3 as compared with CS. Among treatments T1, T2, and T3, the maximumpH (7.20 ± 0.07),OMdegradation (77.06%), loss of organic matter (6.32 ± 0.42%), and WH (32.17 ± 0.32%) were observed in T3. Additionally, the lowest EC (1.15 ± 0.02 mS/cm) and BD (1.06 ± 0.02%) were observed in T3. Further a significant increased difference (at P < 0.05) in shoot length (21.40 ± 1.01 cm), leaves’ area (293.20 ± 16.33 cm2), fresh weight (88.22 ± 7.30 g), and dry weight (12.10 ± 0.91 g) of the plant were observed in T3. Conclusion The poultry manure compost’s aerated rate (0.25 L min−1 kg−1 OM) in T3 was observed to be more mature and stable as compared with T1 and T2.

        ( Fawad Khan ),( Jayanta Kumar Basak ),( Frank Gyan Okyere ),( Elanchezhian Arulmozhi ),( Ji-hoon Park ),( Deog-hyun Lee ),( Hyeon-tae Kim ) 한국농업기계학회 2019 한국농업기계학회 학술발표논문집 Vol.24 No.1

        Optimal strawberry production requires a favorable environment and availability of essential nutrients for growth. Major elements such as NPK is required in the optimal quantity, followed by secondary elements to aid the growth of strawberry plants. Hence this study was conducted to analyze the effectiveness of growth (growth rate) of strawberry plants in different media using image processing techniques. The medium for growth was labeled Compost A and B. Compost A (Bioplus Coco peat) was a standardized compost made of coconut and other biodegradable materials which are commonly used in South Korea for vegetable production. Compost B was prepared from the mixture of poultry manure and sawdust (wood chipping mill) using a concrete mixer while maintaining a C/N ration of 65% and 25% respectively. Compost B was mixed with sandy-loam soil at different rates of 15%, 30% and 45% (T1, T2, and T3). The essential nutrients were analyzed on both composts at the early and later stages of growth of the strawberry. The results of the experiments show that plants in compost A recorded an average growth rate of 65% per week. Analysis of nutrients availability showed that more than 60% of nutrients available at the early stage of growth had been used up by the plants at the latter stage of growth. Plant growth rate in compost B was highest in T3 mixture (53% growth rate/week) as compared to the T2 mixture ( 45% growth rate/week) and T1 mixture (34% growth rate/ week) It was concluded a 45% mixture of Compost B and sandy - loam soil could be used as an alternative growth medium for the cultivation of strawberries plants.

        Ensuring Trust and Confidentiality for Adaptive Video Streaming in ICN

        Fawad Khan,Hui Li 한국통신학회 2019 Journal of communications and networks Vol.21 No.6

        With the dissemination of huge amount of video contentover the internet, information centric networking (ICN) hasemerged as a potential candidate to effectively exploit it and improvethe QoS. ICN decouples content from its location by caching,which can later be retrieved by consumers from their nearest locations. Various experimental studies have depicted the performancemerits of dynamic adaptive streaming via HTTP (DASH) over ICNfor improving QoS. However, there are two challenges that needto be addressed in the context of DASH over an ICN environment. The first one from content consumer domain is that the relevance,integrity, and provenance (RIP) of content should be guaranteed. RIP ensures trust establishment between publisher and consumerof content. The second one that concerns the content publisher isthe confidentiality of DASH media, so that any consumer can viewthe particular quality or resolution of video based on his designatedprivileged rights. We address these two mentioned issues with thecontext of DASH over ICN. The performance and security analysisof our scheme depict its effectiveness for enforcing access control ofadaptive streaming media in an ICN environment.

        Fawad, U.,Kim, H.J.,Khan, S.,Khan, M.,Ali, L. Elsevier 2016 SOLID STATE SCIENCES Vol.62 No.-

        <P>In this study, lithiumyttrium borate (LYBO) phosphor was doped with various concentrations of trivalent dysprosium ions. To produce these phosphors, the raw materials were sintered. The phase conformation, crystallinity, grain size, and overall morphology of the synthesized phosphors were studied with X-ray diffraction and scanning electron microscopy. The optimized LYBO phosphor, i. e., the LYBO phosphor that exhibited the highest X-ray-and ultraviolet (UV)-induced photoluminescent intensities, had a Dy3+ concentration of 4 mol%. Photoluminescence analysis showed that this phosphor could be easily excited with near-UV light (300-400 nm). The dominant photoluminescence bands were found in the blue (480 nm) and yellow (577 nm) regions of the visible spectrum. The light yield of the X-ray-induced luminescence of the optimized Li6Y(BO3)(3): Dy(3+)was found to be 66% of that of the commercially available X-ray imaging material, Gd2O2S: Tb3+ (GOS). The chromaticity coordinates of the Li6Y(BO3)(3): Dy3+ phosphor were x = 0.34 and y = 0.32, which agree well with achromatic white (x = 0.33, y = 0.33). The results of this study show that the synthesized Li6Y(BO3)(3): Dy(3+)phosphor could be used as X-ray imaging material. (C) 2016 Elsevier Masson SAS. All rights reserved.</P>
