The information retrieval (IR) process often encounters a challenge known as query-document vocabulary mismatch, where user queries do not align with document content, impacting search effectiveness. Automatic query expansion (AQE) techniques aim to mitigate this issue by augmenting user queries with related terms or synonyms. Word embedding, particularly Word2Vec, has gained prominence for AQE due to its ability to represent words as real-number vectors. However, AQE methods typically expand individual query terms, potentially leading to query drift if not carefully selected. To address this, researchers propose utilizing median vectors derived from deep median networks to capture query similarity comprehensively. Integrating median vectors into candidate term generation and combining them with the BM25 probabilistic model and two IR strategies (EQE1 and V2Q) yields promising results, outperforming baseline methods in experimental settings.

Snapshot of Technology Business Incubators in China
Nasir Mahmood,Cai Jianfeng,Farhan Jamil,Hina Munir,Jintao LU,Mustafa Khan,Yue Cai 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.7
In the contemporary world, the production of suitable goods and commodities and business developments, the business technology incubators are considered important for the inception of new ideas and combining them with the available resources. Similarly, business and technology incubators are considered a backbone to accelerate the innovation and new business development structure of national economies. The business incubators in China are flourishing by leaps and bounds since the mid of 1990s. This paper aims to explore the performance of technology business incubator in china. In this study the incubator data which was compiled by Ministry of Science and Technology (MOST) China was taken for performance evaluation in china. The performance of incubator in 2002 and in 2012 was assessed by comparison of total number of tenants, total income of tenants, number of graduated tenants and number of employees of tenants, further, in 2012 the association of number of invention patent with the accumulated number of tenants obtained investment and finance is assessed, and this paper also presents the graduated firms number every year in China. These results show that the performance of technology incubators is increased during the last decade.

Business Incubators: Boon or Boondoggle for SMEs and Economic Development of Pakistan
Nasir Mahmood,Cai Jianfeng,Farhan Jamil,Jawad Karmat,Mustafa Khan,Yue Cai 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.4
In this age of technological development, business incubation system is an important tool, for the government to implement and facilitate technological innovation and entrepreneurship development. An effective business incubation system renders an important role in the nourishment of local, national and regional economies by producing employment opportunities & development of SMEs. This study presents evidence that suggests business incubators are important for economic development especially for developing countries like Pakistan. A comprehensive survey was carried out to analyze the current functional status of business incubators, along with the services provided by those incubators, with their success & shortcoming links with incubation system in Pakistan. The importance of business incubators for the promotion of entrepreneurship, development and technological innovation, addressed with an assessment of the needs of Pakistan economy. This is followed with an evaluation of the requirements to be dealt before incubators can leave the desired effects on the improvements of the entrepreneurship and technological innovation. Finally, the findings reveal implications for the future development programme of business incubators in Pakistan with the policy recommendation.

Detection of Water Cloud Microphysical Properties Using Multi-scattering Polarization Lidar
Jiaming Xie,Xingyou Huang,Lingbing Bu,Hengheng Zhang,Farhan Mustafa,Chenxi Chu 한국광학회 2020 Current Optics and Photonics Vol.4 No.3
Multiscattering occurs when a laser transmits into dense atmosphere targets (e.g. fogs, smoke or clouds), which can cause depolarization effects even though the scattering particles are spherical. In addition, multiscattering effects have additional information about microphysical properties of scatterers. Thus, multiscattering can be utilized to study the microphysical properties of the liquid water cloud. In this paper, a Monte Carlo method was used to simulate multi-scattering transmission properties of Lidar signals in the cloud. The results showed the slope of the degree of linear polarization (SLDLP) can be used to invert the extinction coefficient, and then the cloud effective size (CES) and the liquid water content (LWC) may be easily obtained by using the extinction coefficient and saturation of the degree of linear polarization (SADLP). Based on calculation results, a microphysical properties inversion method for a liquid cloud was presented. An innovative multiscattering polarization Lidar (MSPL) system was constructed to measure the LWC and CES of the liquid cloud, and a new method based on the polarization splitting ratio of the Polarization Beam Splitter (PBS) was developed to calibrate the polarization channels of MSPL. By analyzing the typical observation data of MSPL observation in the northern suburbs of Nanjing, China, the LWC and CES of the liquid water cloud were obtained. Comparisons between the results from the MSPL, MODIS and the Microwave radar data showed that, the microphysical properties of liquid cloud could be retrieved by combining our MSPL and the inversion method.
