“…Using LabVIEW, the virtual instruments were earlier developed to demonstrate the instrumentation principles (Jensen, 2011), study the oxidase reactions (McDonald and Tipton, 2010), measure the heart and lung sounds (Altrabsheh, 2010), and also for the determination of rate constant (Meng et al, 2009), trace metals (Economou and Voulgaropoulos, 2002), and morphine (Lenehan et al, 2002), etc. Development of virtual instrument with the help of user-friendly graphical programming languages allows fast program development, and its execution speed is quite comparable with the conventional languages C and Cþþ.…”

“…In most cases, the VI has the possibility of modification, the facility of personalization to the specific necessities of each user, and the use of programming language [22]. The virtual instruments combine nonexclusive operation hardware with powerful software, obtaining a scalable architecture instrument, as a result, with the possibility of being modified if required [23][24][25].…”

Through a reaction of alkaline transesterification of soybean oil using sodium methoxide, biodiesel denominated as B100 was obtained, with which four mixtures of diesel-biodiesel B2, B5, B10, and B20 were prepared. Kinematic viscosity and high heating value of the four blends, B100, and diesel were determined. The blends, B100, and diesel were used in a motor of four cylinders in-line engine, air intake at atmospheric pressure with a power of 250 hp and 6000 cm 3 , operating at a constant rate of 850 ± 50 rpm, a temperature of 25°C, and a relative humidity of 50%. To monitor the emissions, rpm, fuel consumption, and temperature in the engine's exhaust manifold, which operates with diesel-biodiesel mixtures, an integral instrument that uses the virtual instrumentation technology was developed in the programming platforms LabVIEW 2010 and ARDUINO. The development and implementation of the virtual instrument allow monitoring in real time the parameters of internal combustion engines and presents the versatility, flexibility, scalability, and capacity to function in equipment that operates with different liquid fuels at a lower cost than the one that conventional systems offered. These characteristics represent a significant benefit in comparison with the measurement and monitoring systems in the present market.

“…4 In addition, the spectrophotometer devices, with their rapid pace of development, are expected to be higher in quality and lower in costs. 5,6 For traditional spectrophotometric measurement, singlelight spectrophotometers are used. This technique is a good method for determination of absorption at a single point of the spectrum.…”

BackgroundIt is possible to see a number of spectrophotometers produced by commercial purposes developed in line with the technical advices identified by the International Commission on Illumination (CIE) in universities' chemistry labs. These devices are employed in measuring and testing materials with unidentified characteristics as well as reporting the results. However, these systems are not modular in design and do not allow updates or modifications. Moreover, when the literature is reviewed, it can be seen that the researches on computer-controlled devices is limited. It is also reported that the devices with user interfaces bring advantages to researchers in terms of time efficiency and safety. MethodsIn this study, a computer-controlled, modular and low-cost spectrophotometer is designed to measure material densities contained within liquid samples. The proposed system is composed of a main unit, a data acquisition unit and a user interface. All tasks and relevant arrangements involved in a spectrophotometer application are controlled through an interface developed on LabVIEW graphical development platform; the results of the measurements can be monitored in real time, and it is also possible to store data. Thanks to the modular design, it became possible to change and update the relevant stage as needed. The waveform filter can be selected specifically as visible range, ultraviolet range or both depending on the application. ResultsThe experiment was conducted in the visible range and a waveform filter between 400 and 700 nm was used. In the experiments, an easily accessible materials-methylene blue and copper sulfate solutions-were preferred as samples. For these solutions, the waveforms that give the best absorption values were identified and the density was measured at those values. Furthermore, the nonlinearity and repeatability characteristics of the proposed spectrophotometer were analyzed. For this purpose, measured values were compared with the acquired values from another commercial instrument that is already used in medical field. Measurements were repeated 50 times for copper sulfate and 43 times for methylene blue solutions. ConclusionsAfter statistical analysis, it was observed that the reliability of the proposed system is high.
