The research examined the use of Information Retrieval Tools (IRTs) by the post graduate students of Mehran University of Engineering and Technology. The research used descriptive survey and was carried out over a period of six months between August 2016 and January, 2017. The sample size comprise of 2,000 postgraduate students which were randomly selected from different faculties/institutes and were served with copies of the questionnaire. A total of 1,970 copies of useable questionnaire were retrieved which represent 98.5% response rate. The responses were collated and analyzed using frequency counts and percentages. The outcome shows that respondents make use of IRTs for a variety of purposes and that university library's user education and information literacy program forms the key source of their knowledge of IRTs' usage. Through it, it can be safely concluded that the university library plays major role in assisting the students to make use of IRTs. Secondary findings show that the main IRTs made use of by the respondents is the Internet Search Engines. Furthermore findings of the study also revealed that the use of the tools has impacted positively on their social and academic life and has also enhanced their global knowledge of different issues. The major constraint to student's use of the tools is that of Internet fluctuations. The paper concludes with recommendations on the need to give training on the use of IRTs to students.

Knowledge sharing (KS) is a culture that has been encouraged and supported by higher educational institutions (HEIs) in Sindh. This study applies Planned Behavior Theory (TPB) and Social Capital Theory (SCT). Identifying factors related to the KS intentions of a faculty member in the public sector.

The purpose of this study was to examine the impact of perceived control behaviour and perceived external pressure on purchase intention to use e-Commerce during COVID-19 and mediating role of social norms between perceived control behaviour and perceived external pressure and the intention to use of e-commerce during COVD-19. Using a cross-sectional design, data was collected from 200 Internet users during COVI-19 from major cities in Pakistan. Furthermore, to test the proposed hypothesis PLS-SEM technique was used. The findings of this study confirm the strong and positive impact of perceived control behaviour and perceived external pressure on purchase intention to use e-Commerce during COVID-19. In addition, social norms mediate the relationship between perceived control behaviour and perceived external pressure and purchase intention to use e-commerce during COVD-19. The results of this study extended knowledge in existing literature in terms of cultural and consumer characteristics especially in the context of developing country like Pakistan and provided practical implication for practitioners and managers.

The aim of this paper was to study the behavior of the information seeking by the researcher scholars of the at Mehran University of Engineering & Technology, Jamshoro, Sindh Pakistan. The overall purpose of the research study was to find out the awareness and information requirements by the researcher for the research purposes which were provided by the Higher education commission digital library. The data was collected from 230 researchers with the help of questionnaire through the Google online form. Data was analyzed in SPSS software. Research findings were majority of researchers were use electronics resources, text books and reference books. Another major finding was students facing the problems to access the electronics resources for information seeking so they need the proper guidance for data which support them in the research.

The most important and very useful element of today's society is information. Searching for information is a process [...]

This research aimed to investigate the current status and online services portfolio of web OPACs and barriers users' face while searching information on web OPACs of public and private sector university libraries in Lahore. The inquirer adopted quantitative survey method and distributed self administrated (peer reviewed and pilot test) questionnaire among 425 library users who were selected using stratified convenient sampling technique. This study illustrated various types of service being offer and uncovered number of barriers and redundancies that users' of public and private sector university libraries face while searching information remotely on web OPACs. This research study would benefit library administrators and web OPAC designers in the make web OPACs more effective. [ABSTRACT FROM AUTHOR]

A web online public access (OPAC) is an online interface of a library that allows users to make transactions online globally. This study aimed to explore the online library services offered by university libraries of Lahore, the level of user's satisfaction with web OPACs and to compare the users' satisfaction with web OPACs public and private sector university libraries in Lahore Punjab. The data was collected on self-developed and self-administrated peer reviewed questionnaire from 16 university library users via survey. The study revealed that both public and private sector university libraries provide basic and advance searching options, different types of search filters and Multifactor services, the t-test results at combined level factor found no significant different (sig=.000) in level of uses' satisfaction with web OPACs of public and private sector university libraries of Lahore Punjab.

Modern and fast developments of wireless technologies have directed to a great demand for resources. It can be seen in the study that the range of existing spectrum is not used effectively, therefore the frequency band should be observed to ensure proper usage and to have the information of primary or licensed user is very much essential. In this research work uplink of LTE (Long-Term Evolution) is observed through MF (Matched Filter) spectrum sensing technique of CR (Cognitive Radio) network. This method examines the existence of signals in minimum possible time, reduces the hindrances between secondary users, increases accurateness of sensing and provides finest choice of threshold. In Uplink the System model which is used is known as SC-FDMA (Single Carrier Frequency Division Multiple Access). Entire simulation/results are prepared in MATLAB environment. This study also provides graphical contrast of simulated and theoretical results of matched filter and energy detection technique. [ABSTRACT FROM AUTHOR]
