Summary

The Digital Trainer laboratory is designed towards students that are starting with digital logic, truth tables and Boole's Algebra.

During the activity, the student sees an Intel FPGA that implements a series of simple truth tables. The student can interact with the FPGA devices to vary the inputs to the system through switches, and observe the outputs through LEDs. The challenge is to determine which logical operator the FPGA implements in each case (e.g. AND, NAND...).

 

Further details

The activity is designed to be relatively simple and straightforward, but at the same time to be engaging for the students. It is designed in a game-like style, and it is based in real hardware (FPGAs). That way, it is not only useful to introduce and obtain familiarity with digital logic, but also it allows students to start seeing the future uses of that knowledge, interacting in a superficial way with FPGA devices, of the same kind that are used in industry.

Interaction with the FPGA devices does not add complexity, since students don't need to program them; they already implement a black box logic (which is precisely the point of the activity).

The laboratory is originally based in an activity that Intel Corporation frequently conducts in its seminars, both hands-on and remote, using their Intel DE1-SoC, Intel DE2-115, or other types of FPGAs.

The acidity of soils can occur due to various processes that promote a pH reduction. These processes occur naturally or by human action. The main sources of soil acidity are associated to hydrogen ions (H+) and aluminum ions (Al+3) in the soil's solution. Exchangeable acidity is determined through the use of neutral salts solutions such as potassium chloride (KCl). The acid ions (aluminum and hydronium) that are held in the colloidal fraction of the soil, that in the presence of a displacing ion (K+), makes those enter the soil solution. Afterward, that solution is titrated with a sodium hydroxide solution of the exact concentration to reach the last point of the neutralization reaction using phenolphthalein as an indicator.

Summary

The Multi-Phase Flowloop laboratory lets you carry out experiments to visualize flow patterns of multi-phase systems that develop in production tubing in possible real-life scenarios. Through variation of the water flowrate and the angle of the tubing itself, you can appreciate the forming of different flow patterns or “cuttings” depending on the chosen values.

 

Further details

Multi-phase systems are found in various industrial scenarios, not being an exception the oil and gas industry. The prediction and determination of the flow pattern in the production tubing is of great importance since this is directly involved with the optimization of the production itself.

Mixtures of hydrocarbons, water, sediments and gases found in reservoirs manifest different behaviors during their transportation to the ground’s surface. Predicting such behaviors enable a better understanding for adequate choice of pumping machinery and pipeline setups for a successful transport to their final processing facility. The Multi-Phase Flowloop test unit helps achieving a better predictiveness of how multi-phase systems behave in real life for further investigation. This enables the user a better comprehension and visualization of how multi-phase transportations react under variable production rates and mixture proportions.

Summary

This lab facilitates magnetic field experiments with a steady current in a straight conductor, whose intensity can be adjusted. A movable Hall sensor measures the field's magnitude at various distances. In this version of the lab students manually record the data.

 

Versions of the lab

In this version of the lab, graphs are not included and data download by the student is not permitted. Instead, the student must collect the data from the sensor readings and the distance to the conductor, similar to a traditional practical experiment. This allows them to construct their own graphs and create custom spreadsheets for data analysis and conclusion drawing.

There is an alternative version of the lab (Magnetic Field with Graph) in which a graph is provided at the end of each experiment and students are allowed to download the data onto a spreadsheet. This version may be especially useful for those students who prefer more direct access to the data collected during the experiment.

 

Magnetic Field

Moving charged particles have the ability to create a magnetic field around them, which can interact with other moving charged particles. In this context, a conductor through which an electric current flows generates a magnetic field in its surroundings. This physical phenomenon is fundamental in numerous technological advances that we find in our daily lives, such as electric motors and various electronic devices.

 

Potential Experiments

Numerous experiments can be performed with our lab setup. Users can observe how the strength of the magnetic field varies with the current that generates it. They can explore the fundamental principles of electromagnetic induction, visualizing the link between a changing magnetic field and the induced electric current. By adjusting the probe's distance from the field, they can experimentally verify the inverse square law of magnetism, delving into the intricate relationship between field strength and distance.

 

Learning Objectives

The lab may cover the following learning objectives:

• Understand the concept of a magnetic field and how it can be generated and measured.

• Recognize the relationship between magnetic field strength and the current that generates it.

• Grasp the principle of electromagnetic induction.

• Comprehend and verify the inverse square law for magnetic fields.

• Develop skills in data collection, analysis, and interpretation in a physics context.

• Enhance their understanding of physical principles and their real-world applications.

Summary

This lab facilitates magnetic field experiments with a steady current in a straight conductor, whose intensity can be adjusted. A movable Hall sensor measures the field's magnitude at various distances. In this version of the labs students are shown a plot with the data and may download it for further processing.

 

Versions of the lab

This version of the laboratory displays a plot at the end of each experiment and allows students to download the data in a spreadsheet. This allows students to analyze the results without needing to gather and plot the data themselves.

An alterantive version of the lab exists (Magnetic Field) in which the plot and the data are not available. That way, in order to analyse the results and reach proper conclusions, students need to gather and plot the data themselves from the discrete sensor readings, similarly to how they would do so in a traditional hands-on lab.

Experiment with it by varying basic parameters such as the opening and the RPM and observe the output, generating electricity and measuring it.

This ultraconcurrent laboratory is based in an experimental practice about X-ray spectroscopy using a LEYBOLD-brand device that is installed in a radiological instrumentation laboratory in the National University of Costa Rica (Universidad Nacional de Costa Rica), located in the Applied Medical Physics building.

The assembly consists of an X-ray tube with a gold (Au) anode, together with a scintillation detector configured with a preamplifier and a digitizer that allows processing information from the measurements made by the detector through software.

The test aims to characterize the beam of the radiation source through the experimental calculation of the spectrum of the X-ray beam produced in the tube, in addition to generating basic notions about radiological instrumentation and how the variation of its parameters is used in industrial and medical applications.

In this laboratory you will be able to work with a texture analyzer (a texturometer) to determine the rheological characteristics associated to the maturation process of fruits and vegetables. You will be able to use this laboratory instruments to analyse the texture of fresh and processed foods and of industrial products. It allows the measurement of various physical parameters.

The texture profile analysis (TPA) is based on sensorial evaluations to detect and eliminate defects. Furthermore, it is used as a research method and for the learning of science, technology and foods.

A robotic arm of the texture analyzer applies the force necessary for the analysis. The robotic arm is coupled with a puncture or compression probe, depending on the required analysis. A platform holds the sample and supports the interaction of the probe with the selected fruit or vegetable. That way, the analytical signal is obtained. The signal is expressed as a force dependant on the time. That way, it is possible to correlate the graphics with various maturation states, and to conclude about the chemical transformations that affect the fruit or vegetable after the harvest.
