In order to fulfill the desired objective, the preliminary study was performed, based on the observation conducted with the blinds that used assistive technology to navigate the Web. For better Speech Recognition, Web Crawler and Speech Synthesizer technologies have been adopted. The designed system detects user‟s speech and then converts speech into text. Moreover, Web Crawler makes relevant links and titles available in a short span. Hence, the Speech Synthesizer read, enable the results converted into an audio format which are understandable by visually impaired users. The research work focuses on easier, efficient and less frustrating access for sightless individuals.

Content-based retrieval and querying the indexed collections are required to access visual information. Content image retrieval is an efficient means of retrieving similar images from large repositories which require high speed and accuracy. The extraction of features is imperative for efficient results. Following research work aimed at colors and texture extraction for enhancing image metadata. The proposed technique was evaluated on WANG datasets using MATLAB. WANG consists of one thousand images of flowers, buildings and forest. Each category consists of one hundred images of size 187x126 or 126x187 in JPEG format. The features were extracted using RGB and HSV. Rotated Local Binary Patterns were used and distances between images was obtained using Euclidean algorithm. The results showed high accuracy and precision.

Mobile learning has become an emerging educational platform which is gaining popularity in the context of developed countries. However, there is research gap that abstains from providing a complete view of mobile learning adoption in the context of developing countries. To the best of our knowledge, no notable conceptual model is proposed in order to measure students’ intention towards mobile learning. In order to address the gap, Mobile Learning Adoption Model (MLAM) is proposed on the basis of Technology Acceptance Model (TAM) and Unified Theory of Technology and Use of Technology (UTAUT) model. An online survey is conducted to collect data from 158 students at undergraduate, graduate and postgraduate level in Pakistan. Structural Equation Modeling (SEM) is employed to observe the data fit for measurement model by using AMOS 20. The results of the study reve...

According to the Global Hunger Report published in 2020, Pakistan was ranked 88th among 107 countries, with 28.5% of the population under-nourished. To address the situation, food resources need to be more effectively utilized. To reduce food wastage, various efforts have been made to identify the issues associated with the lack of adoption of food wastage mobile application(s). Using purposeful sampling and data from 150 respondents collected from a public sector university and a software house, participants’ experience in using selected food wastage mobile applications were evaluated. In terms of usability parameters, the study proposes improvements in the prototype design.

SNS popularity has encouraged researchers to analyze the relationship of activities performed on SNS with user behavior. In doing so, the term "user behavior" is rather used ambiguously with different interpretations, which makes it difficult to identify studies on user behavior in relation to SNS. This phenomenon has encouraged this thorough research on the characteristics of user behavior being discussed in the literature. Therefore, in this study, we aim to identify, analyze, and classify the characteristics associated with user behavior to answer the research questions designed to conduct this research. A mapping study (also called scoping study), which is a type of systematic literature review, is employed to identify potential studies from digital databases through a developed protocol. Thematic analysis is carried out for the classification of user behavior. We identified 116...

In developing countries such as Pakistan, emergency medical services, especially pre-hospital emergency case services, are neglected for quite a long time. In metropolitan cities, timely access to emergency care becomes challenging with the increasing number of population. The objective of this research is to propose an end-to-end communication solution in the form of an integrated platform consisting of applications that could facilitate patients and Rescue Service Providers in critical situations efficiently and effectively. An experimental research approach was adopted to develop integrated emergency response platform. A combination of mobile and web technologies was employed to develop proposed platform. Such platforms are helpful to decrease response time and assist rescue service providers by providing associated information such...

A widely available realisation of an SOA exists in the form of web services. However, to date no standard techniques have emerged for developing SBAs. There is also a lack of consistency in describing the concept itself, and the published literature offers little evidence derived from the experience of developing `real world examples. Aims: The objective of the work described in this thesis was to conduct a series of studies to explore systematically the concept of what constitutes an SOA by using the published literature, to employ this to construct a proof of concept SOA design model based on a real world problem, and in doing so, to investigate how well existing design notations are able to support this architectural style.
