The Impact and Application of 3D Printing Technology
(International Journal of Science and Research (IJSR), 2014-06-12) Mukosera, Macdonald; Mawere, Cephas; Mpofu, Thabiso Peter
3D printing also known as Additive manufacturing technology has been dubbed the next big thing and be as equally wide spread as cellular telephone industry. 3D printers print objects from a digital template to a physical 3-dimensional physical object. The printing is done layer by layer (Additive manufacturing) using plastic, metal, nylon, and over a hundred other materials. 3D printing has been found to be useful in sectors such as manufacturing, industrial design, jewellery, footwear, architecture, engineering and construction, automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, and many others. It has been found to be a fast and cost effective solution in whichever field of use. The applications of 3D printing are ever increasing and it’s proving to be a very exciting technology to look out for. In this paper we seek to explore how it works and the current and future applications of 3D printing.
Production of Bio Fuels from Eichhornia Crassipes Algae
(International Journal of Research Studies in Biosciences (IJRSB), 2014-02-01) Sengudzwa, Thamari; Chirinda, Ngoni; Manyuchi, mercy; Mawere, Cephas
In a bid to promote renewable energy and control of dam pollution, algae, a plant notorious for growing in waste water dams was used to produce algae oil. Algae plantswere collected from the dam and algae oil was extracted using the Soxhlet procedure. Hexane was used as the solvent. A conversion rate of 14% was obtained for an extraction time of 6 hrs. This algae oil will then be trans-esterified to produce a bio fuel. The bio fuel can be used as an alternative to petrochemical fuel and is sulfur free. Moreover, it is proven to be the cleanest fuel for combustion systems.
Profile Impostoring:A Use Case on the Rising Social Engineering Attack on Facebook Users
(International Journal of Science and Research (IJSR), 2014-06-06) Mawere, Cephas; Mpofu, Thabiso Peter
Social engineering attacks have taken a new twist as a growing number of people use online social networking sites to foster social relationships among each other and market products. Of interest is Facebook whose users have exponentially increased; some of these users are prominent individuals with high influence in various communities like celebrities, philanthropists, religious ministers and non- profit organizations. Data retrieval from Facebook profiles is thus becoming a major tool for business which has led to most unsuspecting users being victims of deception. Profile impostoring, also known as identity theft, is increasingly on the rise and becoming an underlying threat to information security. The cyber perpetrators are creating fake Facebook profiles of prominent individuals who have a large following. Ordinary individuals are also not at their mercy. With such high pending risk of identity theft there is need to develop methods that help Facebook fans to automatically detect deception, identify imposters and get them arrested.
