| 1 | Smart Objects Identification System for Robotic Surveillance显示文摘Video surveillance is an active research topic in computer vision.In this paper,humans and cars identifcation technique suitable for real time video surveillance systems is presented.The technique we proposed includes background subtraction,foreground segmentation,shadow removal,feature extraction and classifcation.The feature extraction of the extracted foreground objects is done via a new set of afne moment invariants based on statistics method and these were used to identify human or car.When the partial occlusion occurs,although features of full body cannot be extracted,our proposed technique extracts the features of head shoulder.Our proposed technique can identify human by extracting the human head-shoulder up to 60%–70%occlusion.Thus,it has a better classifcation to solve the issue of the loss of property arising from human occluded easily in practical applications.The whole system works at approximately 16 29 fps and thus it is suitable for real-time applications.The accuracy for our proposed technique in identifying human is very good,which is 98.33%,while for cars identifcation,the accuracy is also good,which is 94.41%.The overall accuracy for our proposed technique in identifying human and car is at 98.04%.The experiment results show that this method is efective and has strong robustness. | Amir Akramin Shafie Azhar Bin Mohd Ibrahim Muhammad Mahbubur Rashid | 2014 | International Journal of Automation and computing2014，11，1： | 3 |
| 2 | Laboratory biosafety measures of SARS-CoV-2 at containment level 2 with particular reference to its more infective variants显示文摘The novel betacoronavirus(Severe Acute Respiratory Syndrome Coronavirus 2,SARS‐CoV‐2)is a pathogen that causes deadly respiratory disease named coronavirus disease 2019(COVID‐19).The incidence of this disease has increased in the last few months affecting 257,832,881 people in 221 countries and 51,68,069 deaths worldwide according to Worldometer at 04:03 GMT on November 22,2021.Thus,the emergence of this disease creates a challenge for health care providers in handling this pathogen and reducing its risk of transmission.In developing countries,this virus is treated in biosafety level 2 laboratories,where a high concentration of pathogen can easily affect the laboratory staff and cause the spread of this disease.Based on the epidemiology and characteristics of the SARS‐CoV‐2 virus already discussed in recent studies,we will provide biosafety guidelines and suggestions for safe handling and transportation of the SARS‐CoV‐2 virus in dealing with the current pandemic situation with a focus on increased infectivity of emerging new variants. | Wafa Naeem Habiba Zeb Muhammad Ibrahim Rashid | 2022 | Biosafety and Health2022，4，1： | 1 |
| 3 | Synthesis and characterization of poppy seed oil methyl esters显示文摘Response surface methodology(RSM) was used to determine the optimum conditions of the methanolysis of crude poppy seed oil using Na OCH3 as catalyst. The experiments were run according to five levels, four variable central composite rotatable design(CCRD) using RSM. The reaction variables, i.e., molar ratio of methanol/oil(3:1–9:1), catalyst concentration(0.5 wt%–1.25 wt% Na OCH3), reaction temperature(25–65 °C), and reaction time(20–90 min) were studied. We demonstrated that the molar ratio of methanol/oil, catalyst concentration,and reaction temperature were the significant parameters affecting the yield of poppy seed oil methyl esters(PSOMEs). The optimum transesterification reaction conditions, established using the RSM, which offered a89.35% PSOME yield, were found to be 7.5:1 molar ratio of methanol/oil, 0.75% catalyst concentration, 45 °C reaction temperature, and 90 min reaction time. The proposed process provided an average biodiesel yield of more than 85%. A linear correlation was constructed between the observed and predicted values of the yield.The gas chromatography(GC) analyses have shown that PSOMEs contain linoleic-, oleic-, palmitic-, and stearic-acids as main fatty acids. The FTIR spectrum of the PSOMEs was also analyzed to confirm the completion of the transesterification reaction. The fuel properties of the PSOMEs were discussed in light of biodiesel standards(ASTM D 6751 and EN 14214). | Umer Rashid Muhammad Ibrahim Imededdine Arbi Nehdi Saud Ibrahim Al-Resayes Sammi Ullah Muhammad Aamer Mehmood Saira Shahzadi | 2016 | Chinese Journal of Chemical Engineering2016，24，8： | 0 |
| 4 | Application of GIS for the identification and demarcation of selective heavy metal concentrations in the urban groundwater显示文摘地下水是喝水的最适当、广泛地使用的来源,它被污染逐渐地从工业、农业的活动威胁。检查这个问题的严厉, 156 件地下水样品在 Faisalabad 城市里从 52 个不同地区的各种各样的深度( 60110 英尺)被收集,在巴基斯坦的第三个最大的宗主国,并且为金属分析了( Zn , Cu , Cd , Ni , Pb , Mn 和 Fe )在 2009 的集中。Quantification 被使用原子吸收分光光度计技术和结果与为喝的标准谁浇质量相比的火焰做。当 Zn, Cd, Ni 和 Pb 的集中在安全的喝的水的推荐层次上面时,结果证明 Cu, Mn 和 Fe 的层次在 WHO 标准下面。在这些重金属的出现之中的关联分析与 Zn 和 Fe 揭示了 Mn 的高度重要、积极的关联。Cd 的重要、积极的关联也与证明在 Cu-Cd 对之间有强壮的协会并且 Cd 集中在学习区域与地下水的深度变化的 Cu 和地下水深度被发现。重金属出现的地区性的模式为风险区域的鉴定和分界用地理信息系统(GIS ) 被印射。集中地图可以被城市的决策者使用减轻地下水污染。 | Sobia ASHRAF Farhat ABBAS Muhammad IBRAHIM Umer RASHID Shoaib KHALID Hammad Raza AHMAD Khalid Rehman HAKEEM Tahir MAJEED | 2015 | Journal of Geographical Sciences2015，25，2： | 0 |
