Research on novel tools for model-based development differs from a mere engineering task by not only developing a new tool, but by providing some form of evidence that it is effective. This is typically achieved by experimental evaluations. Following principles of good scientific practice, both the tool and the models used in the experiments should be made available along with a paper, aiming at the replicability of experimental results. We investigate to which degree recent research reporting on novel methods, techniques, or algorithms supporting model-based development with MATLAB/Simulink meets the requirements for replicability of experimental results. Our results from studying 65 research papers obtained through a systematic literature search are rather unsatisfactory. In a nutshell, we found that only 31% of the tools and 22% of the models used as experimental subjects are accessible. Given that both artifacts are needed for a replication study, only 9% of the tool evaluations presented in the examined papers can be classified to be replicable in principle. We found none of the experimental results presented in these papers to be fully replicable, and 6% partially replicable. Given that tools are still being listed among the major obstacles of a more widespread adoption of model-based principles in practice, we see this as an alarming signal. While we are convinced that this situation can only be improved as a community effort, this paper is meant to serve as starting point for discussion, based on the lessons learnt from our study.

Biohidrogen (gas hidrogen yang terhasil melalui kaedah biologi) ialah salah satu sumber tenaga mampan yang boleh diaplikasi untuk penjanaan elektrik. Hasil tindak balas pembakaran gas hidrogen menghasilkan air tanpa pelepasan gas rumah hijau. Mikroalga merupakan salah satu mikroorganisma yang boleh menghasilkan biohidrogen secara fermentasi fotosintesis dan gelap. Dalam kajian ini, mikroalga tempatan, Chlamydomonas sp. UKM6 telah digunakan untuk menghasilkan biohidrogen menggunakan kedua-dua kaedah fermentasi dalam keadaan anaerobik. Fermentasi fotosintesis dijalankan menggunakan kultur UKM6 yang hidup di bawah sinaran cahaya manakala fermentasi gelap dijalankan dengan menggunakan biojisim UKM6 yang diinokulasi dengan enapcemar daripada efluen kilang kelapa sawit (POME). Gas hidrogen yang terhasil disuntik secara automatik ke dalam sistem sel bahan api menggunakan Arduino Uno yang telah dibangunkan. Dengan menggunakan data yang dipaparkan daripada program tetapan Arduino, biojisim UKM6 dalam fermentasi gelap menghasilkan gas hidrogen dan nilai voltan purata tertinggi masing-masing pada kepekatan 30.89 ppm dan 0.92 mV.

In photovoltaic (PV) systems, the Maximum Power Point Tracking (MPPT) algorithms are applied to obtain maximum efficiency under different atmospheric conditions. Among the MPPT methods, Perturb & Observe (PO) and Incremental Conductance (INC) methods are the oldest algorithms that have been used. Field Programmable Gate Arrays (FPGA) are used especially in applications requiring high speed. FPGA in-the-loop feature is used to test algorithms designed in MATLAB/Simulink environment. In this study, PO and INC methods were designed to work in FPGA environment. Both algorithms were tested under different radiation conditions by using FPGA-in-the-loop feature. The FPGA in-the-loop simulation result of PO and INC methods was shown graphically. Altera DE2-115 development board was used to test PO and INC MPPT algorithms. In addition, PO and INC methods were synthesized using the Quartus-II program. Comparisons of the simplicity of the algorithms were made based on the synthesis results. Thus, by using the FGPA in-the-loop feature and performing the synthesis process, both of the algorithms were tested and the areas covered by the algorithms in the FPGA were compared.

A good study of photovoltaic system requests to have very precise
current-voltage characteristic curves of photovoltaic modules for different technologies. The photovoltaic emulator provides an efficient solution to maintain the same current-voltage output of photovoltaic module. It includes three parts: the PV model, the control strategy, and the power converter. This paper provides three classes of modeling and simulation of photovoltaic arrays and presents the synthesis results of the current-voltage characteristic performances obtained by the modeling approaches. The models of the first class are based on electrical circuit model, those of the second class are based on multiple straight lines model, and for the third class, it is based on the look up table. The mathematical model is built using MATLAB/ Simulink, and an experimental bench was carried out to acquire an up-to-date and representative experimental database of four PV panels. This database is used for the validation of these models for the different PV panel technologies under Moroccan meteorological conditions. Following this comparative study, we came to a high agreement between the experimental and simulated current-voltage characteristics for the emulator under study
The research consists of the automation of a rotating test tunnel, through an interactive platform, with heating systems by means of electrical resistances coupled to test pieces in different geometric configurations. The working fluid is air, applying a flow controlled by a fan through the mobile duct, at different angles of inclination. Thermodynamic variables are monitored by Arduino hardware that allows information processing. The signals are sent and displayed using the platform integrated by the LabView control and design software; Within the programming with the application, the coefficients of natural and forced convection obtained experimentally, showed a deviation of less than 5% compared to the theoretical data in different conditions of heat transfer by this mechanism, taking into account that the temperature sensors have a sensitivity of 0.25 °C, giving the equipment reliability and confidence of up to 95% accuracy, with air speed in the range of 1.5 to 2.4 m/s.
In this study, the rainbow trout was stored under refrigeration conditions (3 ± 1°C) for 18 days. Changes in the resistance levels in head, meat and eyes, changes of color in the head and meat, changes of liquid levels in the skin and meat, and odor values in the head and the meat were measured with Arduino microcontroller card and recorded during the storing period. In order to perform a significant comparison with the data obtained via Ardunio, the total viable count, psychrotrophic count and Enterobacteriaceae count in the fish meat were identified on a daily basis during storage. The results of the study indicated that the resistance value on the meat decreased significantly as the storage period increased; and that the Arduino‐based color, odor and liquid level measurement sensors could be used effectively in identifying the food quality.
