The urbanization in the urban area can lead to many effects, and one of them is limited parking space. In the context of disabled parking spaces, many easily violate that allocated spaces without guilty. For the authorities to monitor the violation of the disabled parking spaces are quite challenging. That is, the authorities would still need to look out for the parking violation by manually observing and looking around, in other words, through their observation.  The purpose of this study is to improve the current Disabled Parking System (DiParkSys) v2.0 by integrating it with GSM notification system. The GSM module assembled in DiParkSys will immediately notify authorities of any violation by giving the coordinate of the violated parking slot. The prototype was first designed using system visualization and schematic diagram. The integration between the alarm and GSM module was then validated using an integration test before the functionality of the prototype was tested using a Test Cases method.

Testing activities for software product lines should be different from that of single software systems, due to significant differences between software product line engineering and single software system development. The cost of testing in software product line is generally higher compared with single software systems; therefore, there should exist a certain balance between cost, quality of final products, and the time of performing testing activities. As decreasing testing cost is an important challenge in software product line integration testing, the contribution of this paper is in introducing a method for early integration testing in software product lines based on feature model (FM) by prioritizing test cases in order to decrease integration testing costs in SPLs. In this method, we focus on reusing domain engineering artifacts and prioritized selection and execution of integration test cases. It also uses separation of concerns and pruning techniques on FMs to help prioritize the test cases. The method shows to be promising when applied to some case studies in the sense that it decreases the costs of performing integration test by about 82% and also detects about 44% of integration faults in domain engineering.

AbstractThe stationary state of resonant absorption of linear, MHD waves in cylindrical magnetic flux tubes is studied in viscous, compressible MHD with a numerical code using finite element discretization. The full viscosity tensor with the five viscosity coefficients as given by Braginskii is included in the analysis. Our computations reproduce the absorption rates obtained by Lou in scalar viscous MHD and Goossens and Poedts in resistive MHD, which guarantee the numerical accuracy of the tensorial viscous MHD code.

Economic growth of countries is one of the fundamental questions in economics. Most African countries are opening their economies for welcoming of foreign investors. As such Ethiopia, like many African countries took measures to attract and improve foreign direct investment. The purpose of this study is to examine the contribution of foreign direct investment (FDI) for economic growth of Ethiopia over the period of 1981-2013. The study shows an overview of Ethiopian economy and investment environment by the help of descriptive and econometric methods of analysis to establish empirical investigation for the contribution of FDI on Ethiopian economy. OLS method of time series analysis is employed to analyse the data. The stationary of the variables have been checked by using Augmented Dickey Fuller (ADF) Unit Root test and hence they are stationery at first difference. The co- integration test also shows that there is a long run relationship between the dependent and independent variables. Accordingly, the finding of the study shows that FDI, GDP per capita, exchange rate, total investment as percentage of GDP, inflow of FDI stock, trade as percentage of GDP, annual growth rate of GDP and liberalization of the economy have positive impact on Ethiopian GDP. Whereas Gross fixed domestic investment, inflows of FDI and Gross capital formation influence economic growth of Ethiopia negatively. This finding suggests that there should be better policy framework to attract and improve the volume of FDI through creating conducive environment for investment.
