The Namibian lower courts in the pursuit to address poor service delivery and inefficiency, implemented the Namibian Courts Information System (NAMCIS) in magistrates' courts across the country. NAMCIS handles case-flow management and financial transactions. The current setup of these information systems is not centralised and each NAMCIS operates from a stand-alone server. This has seen challenges with systems administration and data reporting, whereby maintenance, as well as administration of the systems, is time-consuming and the information is inaccurate. Integrating the lower courts' information systems is proposed as an aid to the issues at hand. A qualitative research strategy was employed to allow the researcher to gain an in-depth understanding of the lower courts' computing environment. The study adopted a case study design, whereby the Office of the Judiciary was the case. Semi-structured interviews and open-ended questionnaires were used for data collection. Data was analysed interpretively. Based on the findings from the analysis, an integration model was developed. This study will act as a guide to industry practitioners who will embark upon the integration of NAMCIS since each systems integration exercise is unique to its environment.

Cyber-Physical systems (CPS) combine software with the physical world. For this purpose, CPS must model physical behavior in software. However, a software-based model cannot always accurately reflect the physical world. Often the model is a simplification of complex physical processes, or it suffers from measurement errors, or the physical side is subject to modifications and parameter drift, or the model is simply subject to misconceptions. It is an open research challenge how we can verify that physics and software-based model fit together. However, to rely on CPS in real-world scenarios we must ensure that physics and model are aligned. We propose a model formalism based on hidden Markov models that considers uncertainty and unknown phenomena and is robust enough to allow the analysis of CPS when working with error-prone data. More specifically, given observation data and an instance of the proposed model for a CPS (both of which may be flawed) the proposed formalism allows us to quantify the suitability between physics and model. If, however, a given model instance is deemed correct, the formalism enables methods which identify and smooth corrupt observation data as well as compute the most likely sequence of events for a given set of observations. Additionally, the formalism enables the learning of a suitable model according to given observation data. The model formalism will be tested with a simulation and a case study of an overhead traveling cargo crane system.

We present ABS, a software for Abstraction-Based Synthesis of controllers for continuous-state control systems. The tool distinguishes itself from previously known such software by being formally correct, i.e., any controller synthesized by ABS is mathematically guaranteed to solve the control problem provided as input. ABS achieves this quality by providing an input language with mathematically defined semantics and a respective compiler, and by carefully taking into account all numerical and rounding errors that might be incurred at either compile- or run-time. To mitigate computational overhead caused by the aforementioned approach, ABS implements, e.g. on-the-fly synthesis algorithms with greatly reduced memory requirement. The tool is currently applicable to invariance and reachability problems and requires state measurement. We discuss structure, algorithmic details and basic usage of ABS, and we demonstrate on two examples that its performance compares favorably with that of competing, not formally correct synthesis software. The source code of ABS is publicly available. See http://***/gunther/pubs/***

In quantum computing, state preparation is the problem of synthesizing circuits that initialize quantum systems to specific states. It has been shown that there are states that require circuits of exponential size to be prepared (when not using measurements), and consequently, despite extensive research on this problem, the existing computer-aided design (CAD) methods produce circuits of exponential size. In this paper, we show how CAD based state preparation can be made scalable by using techniques that are unique to quantum computing: measurements, and the resulting state collapses. With this approach, we are able to produce wide classes of states in polynomial time, resulting in an exponential improvement over existing CAD methods.
