This paper shows the smart walking stick based on ultrasonic sensors and Arduino for outwardly debilitated individuals. There are roughly 37 million individuals over the globe who are visually impaired as indicated by the World Health Organization. Individuals with visual inabilities are regularly subjected to outer help which can be given by people, trained dogs, or electronic gadgets as supportive networks for basic assistance. Thus, this played as the motivation to develop a smart cane white stick to survive these restrictions (...) which includes ultrasonic sensors at particular positions to the stick that gave data about nature to the client by initiating the signal sound and vibrations. We proposed minimal effort and light weight framework structured with micro controller that processes signal and alerts the visually impaired person over any obstacle, water or dark areas through beeping sounds or vibrations. The system comprises of obstacle and moisture detection sensors for process of receiving, processing and sending signals to the alarm system which finally alerts the user for prompt action. The system was designed, programmed using Java language and tried for exactness by the visually impaired. Our gadget can recognize obstacle inside the separation of around 2m from the client.

Throughout his political works, Plato takes the aim of politics to be the virtue and happiness of the citizens and the unity of the city. This paper examines the roles played by law in promoting individual virtue and civic unity in the Republic, Statesman, and Laws. Section 1 argues that in the Republic, laws regulate important institutions, such as education, property, and family, and thereby creating a way of life that conduces to virtue and unity. Section 2 argues that in (...) the Statesman, the political expert determines the mean between extremes and communicates it to citizens through laws that guide their judgment and conduct, so that they become virtuous themselves and the city is unified; this account of the role of law suggest how even non-expert legislation can contribute to virtue and unity. Section 3 argues that the Laws affirms and develops the idea that citizens should know and accept the laws to become virtuous themselves and to unify the city, and explains how the persuasive preludes and the sanction for violation attached to laws contribute to citizen virtue and civic unity.

This new edition introduces students to fresh approaches to Platonic dialogues while (...) advancing the next generation of research. Of its seventeen chapters, nine are entirely new, written by a new generation of scholars. Six others have been thoroughly revised and updated by their original authors. The volume covers the full range of Plato's interests, including ethics, political philosophy, epistemology, metaphysics, aesthetics, religion, mathematics, and psychology. Plato's dialogues are approached as unified works and considered within their intellectual context, and the revised introduction suggests a way of reading the dialogues that attends to the differences between them while also tracing their interrelations. The result is a rich and wide-ranging volume which will be valuable for all students and scholars of Plato. (shrink)
