Though existing search engines work well to a certain extent but they still face problems like word mismatch which arises because the majority of information retrieval systems compare query and document terms on lexical level rather than on semantic level and short query: the average length of queries by the user is less than two words. Short queries and the incompatibility between the terms in user queries and documents strongly affect the retrieval of relevant document. Query expansion has long been suggested as a technique to increase the effectiveness of the information retrieval. Query expansion is the process of supplementing additional terms or phrases to the original query to improve the retrieval performance. The central problem of query expansion is the selection of the expansion terms based on which user's original query is expanded....

One such amalgamation is Mixed Reality, which allows for physical and digital objects to co-exist and interact in real time, and it has been used in different areas such as entertainment to military training. This research explores the possibilities for creating collaborative mixed reality in an educational context. In this paper, we developed two (2) simulated realities. The one uses Conventional Screen typically found or see in games and where there are perspective cameras which is First Person Perspective and Third Person Perspective. While the other one is inside Mixed Reality paradigm, where reality and virtual objects co-exist, and used the Leap Motion Controller to support mid-air gestures (controls). We performed comparison between the two simulations and a...

Utilizing sensors such as alcohol level detector, crash/impact sensor, Internet connection thru 3G, accelerometer, Short Message Service (SMS) and cloud computing infrastructure connected to a Raspberry Pi Zero-W and integrating a separate Arduino board for the antitheft tracking module is used to develop the propose Internet-of Things (IoT) device. Using quantitative method and descriptive type research, the researchers validated the results from the inputs of the participant who tested the smart helmet during the alpha and beta testing process. Taking into account the ethical consideration of the volunteers, who will test the Smart Helmet. To ensure the reliability of the beta and alpha testing, ISO 25010 quality model was used for the assessment focusing on the device accuracy, efficiency and functionality. Based on the inputs and results gathered, the proposed Smart Helmet IoT device can be used as a tool in helping a motorcycle rider when an accident happens to inform the first-responder of the accident location and informing the family of the motorcycle rider.

Hackers have now become the warriors of the internet. They attack and do harmful things to compromised system. This paper will show the methodology use by hackers to gained access to system and the different tools used by them and how they are group based on their skills. It will identify exploits that can be used to attack a system and find mitigation to those exploits. In addition, the paper discusses the actual implementation of the hacking phases with the virtual machines use in the process. The virtual machines specification is also listed. it will also provide means and insights on how to protect one system from being compromised.

Survey questionnaires were used to examine the familiarity with the technology used in various social media, video conferencing, and learning management systems of 188 university teachers and the use of descriptive data to explore its findings. The respondents were asked to understand online teaching-learning to course design, course communication, time management, and technical competence. Designing the course learning module and activities should be one of the faculty's important readiness and competencies in delivering an online teaching-learning environment. Managing and creating their course in a limited time before offering the course online are challenges for the faculty. Based on the result of the study, it revealed that there were significant differences between readiness, competencies, and challenges with respondents' different demographic variables. It can be concluded that technical skills are necessary for implementing online teaching-learning. Integrating the new normal of teaching-learning online is not an easy task for the faculty and requires various skills in preparing the course materials for online classes. The study contributes to understanding faculty readiness and competencies for using the new normal of teaching and learning. Hence, the findings of this study have implications for the schools to consider teachers' competency when encouraging them to implement online teaching-learning education.
