Abstract: Mobile phones are an essential part of our day to day living. The increased reliance on mobile phone devices for communication, information sharing, connectivity and entertainment calls for a greater need to keep this device in a functional condition at all times. The epileptic nature of utility power supply, non-accessibility to power in remote locations and affordability of power due to high tariffs calls for a relative option to maintain connectivity of mobile phones. This research proposes to develop wearable embedded powered energy sources for charging mobile phones as a backup for instant and seamless charging of the phone battery once it drains. Our research addresses the inability of mobile phone users to charge their flatten phone batteries conveniently and seamlessly anytime and anywhere they find themselves. The hybrid powered charging system has the ability to harvest dissipated heat within the body of the phone and heat sources from the environment using an energy harvester, alongside the second energy source provided by the solar panel. The energy harvester will serve as a cooling measure to the device to maintain a stable temperature. The entire embedded device not only serves as an alternative power supply but also a protective covering to the mobile phone.

Abstract: The emergence of Linked Data and Linked Open Data technologies in the library and information service environment has altered the platform of bibliographic standards and models. Despite the perception that Linked Data technology will soon be the standard for creating metadata for information resources management in libraries, there tends to be very low level of adoption of this emerging technology in the developing economy. This study examined the level of integration, challenges and potential solutions in the adoption of Linked Data (LD) and (LOD) in academic libraries in Nigeria. Survey research design was adopted for the study. This consists of Questionnaire instrument distributed to Library and Information professionals in Nigeria. Seventy-one responses were received across seventeen higher institutions in Nigeria. The study exposed that most of the academic libraries in Nigeria have not started the implementation of linked data standards at all. The major challenges in the adoption of LD in Nigeria are lack of in-depth knowledge on the potential values and procedural activities of LD and LOD technology amongst librarians and information managers, and poor infrastructure, coupled with the concerns that the system could be hacked. The study identified the need for investment of both social and financial capital into LD technology. Librarians and other key stakeholders should be exposed to trainings and events on LD application. Such trainings can be pioneered by the host institutions.
