Operators that Reduce Work and Information Overload
Sabir Abbas,Shane zahra,Muhammad Asif,khalid masood International Journal of Computer ScienceNetwork S 2023 International journal of computer science and netw Vol.23 No.9
The "information roadway" will give us an impact of new PC based assignments and administrations, yet the unusualness of this new condition will ask for another style of human-PC association, where the PC transforms into a sharp, dynamic and customized partner. Interface administrators are PC programs that use Artificial Intelligence frameworks to give dynamic help to a customer with PC based errands. Operators drastically change the present client encounter, through the similitude that a specialist can go about as an individual collaborator. The operator procures its capability by gaining from the client and from specialists helping different clients. A couple of model administrators have been gathered using this methodology, including authorities that give customized help with meeting planning, electronic mail taking care of, Smart Personal Assistant and choice of diversion. Operators help clients in a scope of various ways: they perform assignments for the client's sake; they can prepare or educate the client, they enable diverse clients to work together and they screen occasions and methods.

Effects of Climate on Rice Yield in the Punjab Province, Pakistan
abbas sohail,HUSSAIN SABIR,이승호 대한지리학회 2020 대한지리학회지 Vol.55 No.3
This study presents the effects of climate on rice yield in the Punjab province of Pakistan. A correlation method was employed to examine the relationship between climate elements and rice yield from 1989 to 2018. The effects of climate on rice crop is estimated using the stepwise regression on the significant correlation elements. The analysis founds the positive relationship of rainfall and rice yield at re-plantation stage in the Central and Southern regions. The maximum temperature of re-plantation stage showed a negative relationship with rice yield in the Southern and Western regions. The minimum temperature of tillering, stem elongation and flowering stages had a negative relationship with rice yield in the Central region. The maximum temperature of flowering stage was indicated a negative relationship to rice yield in the Southern and Western regions. The stepwise regression analysis confirms a significant positive effect of rainfall to rice yield in the Southern region and a significant negative effect of maximum temperature on rice yield in the Southern and Western regions at re-plantation stage. The minimum and maximum temperatures of flowering stage negatively affects rice yield in the Central and Western regions respectively.

Urban Growth and Its Effect on Temperature Trends of Lahore City, Pakistan
Sohail Abbas,Mian Sabir Hussain,Sujeong Im,Seungho Lee,Safdar Ali Shirazi 건국대학교 기후연구소 2018 기후연구 Vol.13 No.3
The current study deals with the effect of urban growth and urbanization on temperature trends over Lahore city of Pakistan. This research was conducted using mean monthly temperature data for the period of 1950-2017. The urban population growth, urban expansion, the increase of vehicles and factories as well as the expansion of built up area have influenced on the change of temperature in Lahore city. The annual trends of temperatures have been analyzed, and their statistical significances are calculated by the linear regression method. It has been deduced that there is a close relation between temperature change and urban growth. The findings are as follows; the mean minimum temperature rises greater than the maximum temperature at urban station and rural station. However, the maximum temperature is not rising positively and thus significantly at both stations. The findings show the fact that mean minimum temperature increasing more quickly after the 1995 due to the increase of urban development in Lahore city in which the built up area has increased from 66 km² to 740 km² since 1950. A massive increase in the numbers of vehicles have also influenced on the change of temperature in the city. However, the mean maximum temperature at rural station of Lahore has significant effect during 1973-1997.

A Review of Studies on Changes in Precipitation Features over Pakistan
Sohail Abbas,Mian Sabir Hussain,임수정,신보미,이승호 건국대학교 기후연구소 2021 기후연구 Vol.16 No.4
This study provides a comprehensive review on the trend of precipitation research work over Pakistan. An integrated literature review is developed by combining the various content analysis to explore a systematic trend of precipitation studies in Pakistan. The review was extended up to Indian research work of precipitation to identify the role of affecting elements to regional precipitation of Pakistan. The review is focused on two national journals and eighteen international journals about geography, climate, and meteorology during 1981-2020. The proportion of reviewed articles was 84 and 16 percent for international and local journals respectively. Various features of precipitation research in international journals have rapidly increased during 2009-2020, which was four-time greater than research published during 1981-2008. Regarding various features of precipitation, the ratio of reviewed studies was 54%, 21%, 16%, and 6% for atmospheric circulation, annual and seasonal precipitation, extreme precipitation, and regional distribution of precipitation respectively. While the studies of climate change and its impact on human was not big in numbers in Pakistan. The review of precipitation studies revealed that the aspect of precipitation intensity was more focused on by climate scientists during the last three decades. The occurrence of precipitation intensity indicates an increasing trend of extreme events particularly in the central plain, northwestern mountain, and Kashmir region during the monsoon season. There is no specific research was studied to assess the trend shift changes of precipitation in the recent decades.

Spatial Patterns and Temporal Trends of Precipitation in the Punjab, Pakistan, 1981-2015
Saadia Sultan Wahla,Safdar Ali Shirazi,Sohail Abbas,Mian Sabir Hussain,이승호 건국대학교 기후연구소 2019 기후연구 Vol.14 No.3
The objective of the current study is to investigate and evaluate the annual and seasonal rainfall trends and patterns of the Punjab province, Pakistan during the 1981-2015. The spatial patterns and temporal trends were identified through the Modified Mann Kendall test. Finding revealed that 13 weather stations of Punjab province have shown the statistically significant decreasing trend of annual and summer monsoon rainfall during the study period. From further investigation, the rainfall during the summer monsoon period (JJAS) found to be increased by 12.45%, similarly the rainfall during the whole of year be also increased by 18.75%. The significant decreasing trends observed with the higher percentage change in annual and monsoon rainfall for the stations of Sialkot and Lahore in the northern and central Punjab. The empirical evidences suggested that northern Punjab gets more moisture as compared the Southern and Western Punjab. This study suggests intensive empirical research in the future to evolve further spatio-temporal trends in the rainfall pattern of Punjab.
