off really fast to produce the
same effect
• The on-off pulsing happens so
quickly, the connected output
device “sees” the result as a
reduction in the voltage

To measure the intensity of light using LDR sensor by calibrating voltage wit...Ankita Tiwari

The document describes an experiment to measure light intensity using an LDR sensor calibrated with LabVIEW. An Arduino board reads the voltage across the LDR and LabVIEW converts it to lux using equations relating resistance, voltage and light intensity. LabVIEW establishes a front panel and block diagram to communicate with the Arduino, send new delay interval values to control motor speed, and clear registers to avoid data overflow. The experiment successfully measured light intensity by calibrating LDR voltage to lux in LabVIEW.

Analogue and digital systemsEdmund Merren

Analogue systems process continuous analogue signals that can take on any value within a range, while digital systems process discrete digital signals that can only take on a limited number of predefined values, usually just two values of high and low. Digital systems are made up of logic gates and other digital components and can process information with greater precision than analogue systems due to their discrete nature. Noise is also easier to eliminate from digital signals compared to analogue signals.

Integration of Utility Data into 3D BIM Models Using a 3D Solids Modeling Wor...Safe Software

Jacobs has developed a 3D utility solids modelling workflow to improve the integration of utility data into 3D Building Information Modeling (BIM) environments. This workflow, a collaborative effort between the New Zealand Geospatial Team and the Australian Data Capture Team, employs FME to convert 2D utility data into detailed 3D representations, supporting enhanced spatial analysis and clash detection. To enable the automation of this process, Jacobs has also developed a survey data standard that standardizes the capture of existing utilities. This standard ensures consistency in data collection, forming the foundation for the subsequent automated validation and modelling steps. The workflow begins with the acquisition of utility survey data, including attributes such as location, depth, diameter, and material of utility assets like pipes and manholes. This data is validated through a custom-built tool that ensures completeness and logical consistency, including checks for proper connectivity between network components. Following validation, the data is processed using an automated modelling tool to generate 3D solids from 2D geometric representations. These solids are then integrated into BIM models to facilitate compatibility with 3D workflows and enable detailed spatial analyses. The workflow contributes to improved spatial understanding by visualizing the relationships between utilities and other infrastructure elements. The automation of validation and modeling processes ensures consistent and accurate outputs, minimizing errors and increasing workflow efficiency. This methodology highlights the application of FME in addressing challenges associated with geospatial data transformation and demonstrates its utility in enhancing data integration within BIM frameworks. By enabling accurate 3D representation of utility networks, the workflow supports improved design collaboration and decision-making in complex infrastructure projects
