‘SWIM-Spread Wisdom’ is a wise ecosystem built to spread wisdom through the WISE SWIM Toddlers Game structure. SWIM’s spread wisdom would help to avoid the failure of DAO by using the wise consensus algorithm "Proof-of-Wisdom" This white paper aims to explore the impact of social media on mental health in adolescents and the role of wisdom games in promoting wisdom and environmental awareness in toddlers.
Abstract During the past few years, technology has significantly reshaped the method of assessment. Educational measurement has been moving towards the use of CBT. The underlying purpose of this research is to evaluate the significance of students‟ access to a computer; students' attitude; students‟ perception; computer literacy skills and CBT acceptability as it affect secondary school student‟s preparedness for UTME-CBT. Data were collected with questionnaires distribu...

Introduction The rise of information technology or IT has profoundly affected modern society. Consequently, computers have become devices of daily use. In this paper, the need of computer science education will be reflected on. The analysis will focus on the current situation of today’s society, where ITand telecommunications are playing a crucial role. World Wide Web and advanced IT tools have created new opportunities before computer science. So computers can be c...
Optical fiber in the communication system has become one of the most cabling attractive and commonly used to protection and safely and also transmission longer distance is possible also contain a large number of data rate and the demand for data communication is growing rapidly due to the increasing popularity of the internet and other factors. In order to meet the growing demands for bandwidth, However, there are some limiting factors for optical fibers during the transmission of the s...
As facilitators of 3D printer workshops, the authors developed a survey to gage how the printers are actually being used and whether they support the Next Generation Science Standards (NGSS) requirements, especially in regard to engineering design. The survey response rate was 52% of 68 total participants with the majority conveying that 3D printers do facilitate student understanding of the engineering design process and that the workshops empowered them and their students to tackle projects...
RepRap 3-D printers and their derivatives using conventional firmware are limited by: 1) requiring technical knowledge, 2) poor resilience with unreliable hardware, and 3) poor integration in complicated systems. In this paper, a new control system called Franklin, for CNC machines in general and 3-D printers specifically, is presented that enables web-based three dimensional control of additive, subtractive and analytical tools from any Internet connected device. Franklin can be set up and c...
Additive manufacturing with 3-D printers may be a key technology enabler for entrepreneurs seeking to use disruptive innovations, such as business models utilizing distributed manufacturing. Unlike centralized manufacturing, distributed manufacturing makes the parts and products (the prints) at (or closer to) the source of the demand, cutting out much of the traditional supply chain. Although many expect 3-D printing to take off at the household level and previous work has shown significant r...
The open-source release of self-replicating rapid prototypers (RepRaps) has created a rich opportunity for low-cost distributed digital fabrication of complex 3-D objects such as scientific equipment. For example, 3-D printable reactionware devices offer the opportunity to combine open hardware microfluidic handling with lab-on-a-chip reactionware to radically reduce costs and increase the number and complexity of microfluidic applications. To further drive down the cost while improving the p...
The combination of open-source software and hardware provide technically feasible methods to create low-cost, highly-customized scientific research equipment. Open-source 3-D printers have proven useful for fabricating scientific tools. Here the capabilities of an open-source 3-D printer are expanded to become a highly-flexible scientific platform. An automated low-cost 3-D motion control platform is presented having the capacity to perform scientific applications including: i) 3-D printing o...
Open-source technology not only has facilitated the expansion of the greater research community, but by lowering costs it has encouraged innovation and customizable design. The field of automated microscopy has continued to be a challenge in accessibility due the expense and inflexible, non-interchangeable stages. This paper presents a low-cost, open source microscope 3-D stage. A RepRap 3-D printer was converted to an optical microscope equipped with a customized, 3-D printed holder for a US...
Open source hardware (OSH) development has been gaining momentum in recent years with several communities attempting to formalise its various aspects. One particularly promising area is the design of open source scientific hardware. Previous work has shown that the use of digital fabrication techniques has allowed scientists to make high-quality scientific tools for 1-10% of the cost of commercial proprietary equipment. Open source scientific hardware (and the open science movement in which i...
The recent introduction of RepRap (Self-Replicating Rapid Prototyper) 3-D printers and the resultant open source technological improvements have resulted in affordable 3-D printing, enabling low-cost distributed manufacturing for individuals. This development and others such as the rise of open source-appropriate technology (OSAT) and solar powered 3-D printing are moving 3-D printing from an industry specific technology to one that could be used in the developing world for sustainable develo...
The articles in this issue look at how the development and use of free and open source hardware (FOSH or simply “open hardware”) are changing the face of science, engineering, business, and law. Free and open source software (FOSS) has proven very successful and now dominates the development of software on a global scale. It is available in source code (open source) and can be used, studied, copied, modified, and redistributed either without restriction or with restrictions only to ensur...
