This paper presents an application of a novel approach for detecting and tracking an object with a 2 DOF robotic manipulator which can be equipped with an array of electrically controlled actuators. The said approach utilizes the Image Based Visual Servoing (IBVS) technique. The developed system is able to determine the object pose in real time from features in the image. Object is detected using shaped based approach algorithms of image processing. The position and orientation of the world coordinates of the object being tracked are calculated from the coordinates of the object in image plane using camera’s intrinsic and extrinsic parameters. Experimental results demonstrate the effectiveness of this proposed approach.

Homomorphic Encryption Technologies for Cloud Computing
Khowla Khaliq,Muhammad Usman Bilal,Rimsha Khalid,Muhammad Waseem Iqbal,Muhammad Aqeel,Muhammad Adnan Khan 한국차세대컴퓨팅학회 2022 한국차세대컴퓨팅학회 학술대회 Vol.2022 No.10
Security is the major concern about data especially when we are storing it on the cloud and handing over it to the third force as the cloud resource supplier. We store our important data on the cloud in the shape of cipher-text but we have to convert it to plain text to perform calculations on it, which disturb its security including confidentiality, privacy, authentication, etc. so, our ultimate goal was to introduce some of the best encryption technique for securing data. In this regard, we have discussed Homomorphic Encryption (HE) in our paper. This survey is shown how HE could be used to make secure data on the cloud. HE is a technique in which data (plaintext) is converted in cipher-text (unreadable format). Users can perform required calculations on encrypted data without decrypting it and which does not affect the original form of data. This paper aims to focus on the fully homomorphic encryption technique. For this purpose, many approaches were analyzed and we suggested the best approach at the end of the paper.

Assessment of Air Temperature Trends in the Source Region of Yellow River and Its Sub-Basins, China

Changes in climatic variables at the sub-basins scale (having different features of land cover) are crucial for planning, development and designing of water resources infrastructure in the context of climate change. Accordingly, to explore the features of climate changes in sub-basins of the Source Region of Yellow River (SRYR), absolute changes and trends of temperature variables, maximum temperature (Tmax), minimum temperature (Tmin), mean temperature (Tavg) and diurnal temperature range (DTR), were analyzed annually and seasonally by using daily observed air temperature dataset from 1965 to 2014. Results showed that annual Tmax, Tmin and Tavg for the SRYR were experiencing warming trends respectively at the rate of 0.28, 0.36 and 0.31oC (10 yr)−1. In comparison with the 1st period (1965-1989), more absolute changes and trends towards increasing were observed during the 2nd period (1990-2014). Apart from Tangnaihai (a low altitude sub-basin), these increasing trends and changes seemed more significant in other basins with highest magnitude during winter. Among sub-basins the increasing trends were more dominant in Huangheyan compared to other sub-basins. The largest increase magnitude of Tmin, 1.24 and 1.18oC (10 yr)−1, occurred in high altitude sub-basins Jimai and Huangheyan, respectively, while the smallest increase magnitude of 0.23oC (10 yr)−1 occurred in a low altitude sub-basin Tangnaihai. The high elevation difference in Tangnaihai probably was the main reason for the less increase in the magnitude of Tmin. In the last decade, smaller magnitude of trend for all temperature variables signified the signal of cooling in the region. Overall, changes of temperature variables had significant spatial and seasonal variations. It implies that seasonal variations of runoff might be greater or different for each sub-basin.

Indole-3-acetic acid (IAA) is an important plant hormone required for various plant growth and developmental activities. YUCCA proteins are the enzymes for IAA synthesis that catalyze the rate-limiting step. However, the YUCCA gene family in Japanese apricot has not been thoroughly characterized. Here, we investigated the eff ect of rootstocks on scion growth of Japanease apricot and genes involved in auxin biosynthesis ( YUCCA ). Growth characteristics revealed that the height of ‘Longyan’ [ Prunus mume Sieb. et Zucc] plants with P. mume rootstock were signifi cantly shorter than ‘Longyan’ plants with P. persica rootstock. This study isolated 13 PmYUCCA genes from the Japanese apricot genome. Bioinformatics and expression studies were undertaken to investigate the functions and characteristics of YUCCA genes. The physicochemical properties, gene structure, conserved domains, conserved motif, and phylogenetic relationships of YUCCA genes were determined using bioinformatics analysis. Likewise, we analyzed the expression of PmYUCCA genes in Japanese apricot’s leaf and stem-bark (scion). The expression levels of PmYUCCA3 and PmYUCCA5 genes were noticeably lower in the leaves of ‘Longyan’/ P. mume graft combination than that of the ‘Longyan’/ P. persica graft combinations, suggesting their distinct roles in regulating growth vigor. This research explores the genome-wide identifi cation, characterization, and possible relationship between growth vigor and expression profi le analysis of the YUCCA gene family in Japanese apricot.

Mechanism and kinetics of Rhenium complexes as a surrogate of Technetium-99 (99Tc) is worthy of study from radioactive waste safe disposal perspective. Re(IV)-EDTA was synthesized via the reduction of Re(VII) with Sn(II) in the presence of Ethylenediaminetetracetic acid (EDTA). The Re(IV)-EDTA was then degraded by H2O2 (7–30%) at pH of 3–11 in ionic strength I = 0–2 M solution. The Re- EDTA was observed to degrade more rapidly at pH of ≤ 3–4 than one of ≥ 10–11 and remained stable at pH = 7–9. At a low acidic pH, the complex degradation process was facilitated by protonation and corresponded to the exponential model (y = k. e–nt). In contrast, at an alkaline pH, the degradation was facilitated OH– complexation with Re(IV) and corresponded to a linear model (y = –mt + C). Complex degradation followed the zero-order rate kinetics for the H+ and Re-EDTA parameters, apart from a pH of 3, for which degradation was a better fit to first order kinetics. A higher Re(IV)-EDTA stability at a pH of 7–9 demonstrated that Re(IV)-EDTA (or 99Tc(IV)-EDTA) tends to be more persistent in natural environmental conditions.
