Design of an Interactive Mobile Application for Maternal, Neonatal and Infant Care Support for Tanzania

Reducing maternal and infant deaths’ rates in the developing countries, particularly in sub-Sahara Africa, remain a big challenge. Despite efforts by governments, the reductions have been unsatisfactory. To accelerate the reduction in maternal and infant deaths, m-health has been proposed as a viable, economical and effective intervention, able to reach the low income and disadvantaged groups. Mobile phone-based applications are among the m-health interventions that have been found to have positive outcomes for different healthcare challenges, such as improving clinical attendance and skilled delivery, and reducing perinatal mortality. However, the adoption of smartphone-based applications for health in Tanzania has been slow. Some of the likely contributing factors might be low technology exposure by the majority of the population and English language skills’ limitations. In this work, we developed a mobile application for providing interactive support to users, thus complementing other solutions available such as SMS and other smartphone apps. The main advantage of this app is the presence of interactive features that enable patient-provider communication. We adopted the Rapid application development (RAD) model for developing the application. We used UML modeling language tools for designing the application. The mobile application’s technical architecture uses various technologies and system development tools such as PHP programming language for the web application, MySQL database management system and Android Studio mobile application development platform.

Identifying New Directions in Database Performance Tuning

Database performance tuning is a complex and varied active research topic. With enterprise relational database management systems still reliant on the set-based relational concepts that defined early data management products, the disparity between the object-oriented application development model and the object-relational database model, called the object-relational impedance mismatch problem, is addressed by techniques such as object-relational mapping (ORM). This, compounded with changes in the way data is produced, stored and managed can result in generally poor query performance for SQL produced by object-oriented applications and an irregular fit with cost-based optimisation algorithms, and leads to questions about the need for the relational model to better adapt to a more diverse set of queries. This paper discusses existing database performance optimisation techniques and approaches and makes the argument that current database performance tuning approaches need revisiting to support queries developed through ORM tools. This paper also introduces our current research, which includes exploring concepts such as dynamic schema redefinition; query analysis and optimisation modelling driven by machine learning; and augmentation of the cost-based optimiser model.

A proposed novel enterprise cloud development application model

Currently, there is limited guidance on generic cloud software architecture model for designing and building cloud applications and each platform provider has different standards that influences the way applications are developed and written. In this paper we propose a cloud application development model based on developing services (typically REST API services). We see clear benefits in applying this model to service oriented architecture (SOA) and business process management (BPM) design in order to develop enterprise applications for cloud environments in a systematic, rapid manner. This conceptual model described in this paper is drawn from the core ideas and practices behind REST API, BPM, and SOA. In this paper we focus on the proposed software development model for enterprise cloud applications and services. Throughout this paper we use the term cloud application and cloud service interchangeably. The model described in this paper can be applied to both. Further research on a software-modeling tool that provides a standardized structure for cloud software development and deployment seems to be in order. Supported by a graphical modeling environment, such a tool would utilize a Cloud Resource Provisioning language, will be able to seamlessly deploy and provision cloud resources across multiple cloud service providers. The presented research provides a practical and extensible application development model for cloud platforms. The model described can be used in a variety of applications as well as migration of legacy code to cloud platforms. By using this model, a cloud application can be deployed as small functionally separate components to different cloud nodes. Resource allocation can be defined for these nodes on a per need basis, which minimizes the cost of acquiring a fail over and load balanced system compared to the traditional on premise application development. In this paper, a detailed description of the analysis and development steps of the proposed model is also presented.

Pirax: framework for application piracy control in mobile cloud environment

Mobile cloud computing is an emerging technology that is gaining popularity as a means to extend the capabilities of resource-constrained mobile devices such as a smartphone. Mobile cloud computing requires specialized application development models that support computation offloading from a mobile device to the cloud. The computation offloading is performed by means of offloading application process, application component, entire application, or clone of the smartphone. The offloading of an entire application or clone of the smartphone to cloud may raise application piracy issues, which, unfortunately, have not been addressed in the existing literature. This paper presents a piracy control framework for mobile cloud environment, named Pirax, which prevents mobile applications from executing on unauthenticated devices and cloud resources. Pirax is formally verified using High Level Petri Nets, Satisfiability Modulo Theories Library and Z3 solver. Pirax is implemented on Android platform and analyzed from security and performance perspectives. The performance analysis results show that Pirax is lightweight and easy to integrate into existing mobile cloud application development models.
