Android has become most popular and powerful embedded operating system. Nowadays, it is used in other electronic items other than mobile phones like TV, Camera, etc. The purpose of this study is to find out the difference in performance between the different methods for developing applications due to an increasing market for platform independent applications. In this research work, we present our current findings concerning performance efficiency in cross-platform and native mobile applications (apps) and how they can contribute to a general benchmarking approach. At first, several test cases for evaluating performance of mobile applications are described with which two applications where built to implement a mathematical calculation for both native and hybrid respectively. This is used as benchmark because of the recursive nature and memory usage of both applications for CPU and memory usage. Then, the performance efficiency of native and hybrid apps is compared on a mobile device. The results show that hybrid applications still suffer performance issues in comparison to native apps. The performance deviations and reasons for them are discussed and evaluated. It is concluded that the performance of mobile applications is crucial to user experience and satisfaction.

Pigeonhole is an internal information exchange system, used for communication in an organization. It is a creative, informal and traditional way of dropping and picking messages in a set of small open-fronted compartments usually used in a workplace or other organizations where letters or messages may be left for individuals. The chain of exchange is a kind of 'give-and-return'. It is a bi-directional 'pick-and-respond' information transmission mode. Internal and informal investigations carried out in most departments in Adekunle Ajasin University, Akungba-Akoko (AAUA), Ondo State, Nigeria, however show that the purpose of this dual-mode communication is most times defeated as recipients of pigeonhole-kept information are remote and unaware of any 'visitor' awaiting them. The researchers therefore deem it fit to close up this gap and ensure maximal consumption of the benefits pigeonhole system offers. We are therefore poised through this study, to design and implement a mobile-based, interactive and informative pigeonhole alert system that captures information meant to be archived in a pigeonhole, disseminate the information and monitor the receipt or otherwise of same with appropriate feedbacks. The proposed system allowed for easy and enhanced communication between the administrator incharge of messages (e.g. the office clerk) and the recipients, to ensure proper dissemination of information. The design and implementation were accomplished using Java and XML components of Android Software Development Kit (SDK).

To complete a construction project successfully, you'll need a good project control system. To ensure any chance of success, projects of significant size or complexity must be constantly managed. Control standards are used by the project team to ensure that progress is kept at acceptable levels. The purpose of the research is to look into material control in the Nigerian construction industry. The study's goal was to summarize what was already known about material control in construction production. The information was gathered by distributing a standardized questionnaire to experienced experts on building locations and in workplaces. The results demonstrate that 60 present of the locations employ material preparation to control materials, with quantity surveyors performing the majority of the control planning. The way building materials are created and controlled has problems such as lack of planning, , improper storage, late delivery of components to the job site, and poor material testing. The construction business ought to have a document established for controlling building materials; programme material control education should be undertaken, and the three basic techniques (scheduling, material planning, and ABC analysis) should be incorporated into controlling materials.
