Ghana’s Rabbit Industry

Like many folk traditions of saying “Rabbit, rabbit” to your colleagues on the first day of the month has an unclear origin and has several variations and interpretations.  We use it a reason to explore university research into food sources; the proper business of education communities everywhere.  In one version of the tradition, saying “Rabbit, rabbit” or “White rabbit” as the first words upon waking on the first day of the month is believed to bring good luck for the rest of that month. It is thought to ensure good fortune, happiness, and general positivity throughout the coming weeks.

The specific origins and reasons behind this tradition are difficult to trace, as superstitions often evolve and are passed down through generations. It’s worth noting that this practice is not universally known or followed, and its popularity may vary among different regions and communities.  Ultimately, the saying “Rabbit, rabbit” on the first day of the month is an example of a charming and whimsical superstition that some individuals enjoy participating in as a fun way to start the month on a positive note.

Time Synchronization of Medium Voltage Substations

 

Time Synchronization of Medium Voltage Substation IEDs Using Modbus and Python

Joseph Owusu, et. al

 

Abstract:  Energy demand and supply all over the world is increasing in size and complexity. Anomalous conditions caused by failures in electrical components, human errors and environmental conditions result in electrical faults that can interrupt electricity flow. Substation automation requires precise time synchronization for a variety of Intelligent Electronic Devices for fault diagnosis. The quest for accurate and sequential time stamping of events compels power utility companies to adopt various techniques of time synchronization with an accuracy of a millisecond or a microsecond. Some works adopt the use of time synchronization techniques using protocols such as Network Time Protocol, Precision Time protocol, Simple Network Time Protocol and many more. This work presents time synchronization of IEDs using Modbus protocol and python programming language for a local substation. The system records the output data into a database and displays it on an application software. The time synchronization system was successful alternative for off network systems.

Recognizing signs and doors for Indoor Wayfinding for Blind and Visually Impaired Persons

Mouna Afif, et al

 

Abstract:  Indoor signage plays an essential component to find destination for blind and visually impaired people. In this paper, we propose an indoor signage and doors detection system in order to help blind and partially sighted persons accessing unfamiliar indoor environments. Our indoor signage and doors recognizer is builded based on deep learning algorithms. We developed an indoor signage detection system especially used for detecting four types of signage: exit, wc, disabled exit and confidence zone. Experiment results demonstrates the effectiveness and the high precision of the proposed recognition system. We obtained 99.8% as a recognition rate.
