Data Entry Form Designing Tools and Software Usability in DHIS2

The advent of configurable software has shifted the implementation of software solutions from total reliance on software developers to towards increased participation of end-users. End-users are now able to create software solutions without the need for writing code but through configuration and customisation. Despite the increasing use of configurable software challenges on designing the software platform architecture, process of testing and usability exists in configurable software. The research aimed at evaluating how available interface elements influence usability in DHIS2. Empirical data was collected by studying the design of custom data collection forms for routine health data collection with two groups of users. 80% and 90% were recorded as completion rates of the designed task and overall efficiency of 86.23% and 89.94% was achieved between the two groups. Lack of relevant editing features, increased distance between related objects, lack of conformity to Keep It Simple, Stupid (KISS) and minimalistic design principle were found to be the major challenges affecting the usability.

Modular hardware platform for the development of industrial Internet of Things (IoT) devices

The modular hardware platform architecture for the development of industrial IoT devices is presented as an example of information harvesting and its analysis. Variants of modules implementing typical functions of such devices are given: data acquisition from a distributed array of sensors; preprocessing, aggregation and data transmission; data mining; storage of primary data and analysis results.

E-Learning Platform Directions and Future Expansion With Case Study

When we look at the current situation in the world we can see that world shifts into digital era. This means, it will also influence the learning and educational section. In this science paper we will analyze e-learning platform architecture, propose architecture based on the teaching process and perform comparative analysis of leading e-learning provides.

FLINT: Flows for the Internet of Things

New protocols and technologies are continuously competing in the Internet of Things. This has resulted in a fragmented landscape that complicates the integration of different solutions. Standardization efforts try to avoid this problem, however within a certain ecosystem, multiple standards still require integration to enable trans-sector innovation. Moreover, existing devices require transformations to fit in an ecosystem. In this paper, we discuss several integration problems in the field of Low Power Wide Area Networks in the context of the Port of the Future and propose a new distributed platform architecture, called FLINT. FLINT is a framework to program flexible and configurable flows on a per device basis. A flow is constructed from fine-grained components, called adapters. Due to the modularity of an adapter, users can easily integrate existing software. We evaluated FLINT based on five levels of interoperability and show that FLINT can be used to interconnect non-interoperable systems and protocols on every level. We have also implemented FLINT in a container based environment and demonstrated that a basic configuration has a 99% forwarding rate of 17.500 513-byte packets per second, showing that the architecture can deliver good performance.
