Investigation on material removal rate, surface and subsurface characteristics in wire electro discharge machining of Ti50Ni50-xCux shape memory alloy

Abstract: TiNiCu shape memory alloys have superior properties as compared with NITINOL due to their greater ductility, reduced hysteresis temperature range, and quick actuation response. The present article ...

Security-aware Software Development Life Cycle (SaSDLC) - Processes and tools

Abstract: Today an application is secured using invitro perimeter security. This is the reason for security being considered as nonfunctional requirement in Software Development Life Cycle (SDLC). In Next Generation Internet (NGI), where all applications will be networked, security needs to be in-vivo; security must be functions within the application. Applications running on any device, be it on a mobile or on a fixed platform - need to be security-aware using Securityaware Software Development Life Cycle (SaSDLC), which is the focus of this paper. We also present a tool called Suraksha that comprises of Security Designers' Workbench and Security Testers' Workbench that helps a developer to build Security-aware applications.

Extruded poly(ethylene-co-octene)/fly ash composites – value added products from an environmental pollutant

Abstract: Fly ash (FA) is a by-product generated during combustion of coal and has caused serious environmental concerns. In an effort to utilize FA beneficially, we developed composites from an ethylene-octene random copolymer (EOC) and unmodified as well as surface-modified class-F fly ash (MFA) by twin screw extrusion. Addition of 20 wt% of MFA to EOC improves its tensile strength by 150%; also, MFA improves stress at 100% and 300% strains (M100 and M300) of EOC. Thermal stability of EOC matrix is appreciably improved by the addition of either FA or MFA, while the melting behavior is not appreciably influenced by either. Fractography study reveals an improved adhesion between the EOC and MFA particles up to a filler loading of 20%, beyond which the adhesion between EOC and MFA is weakened causing a reduction in mechanical properties. The ‘flammable’ nature of EOC changes to ‘self extinguishing’ on addition of even 10 wt% of FA or MFA, as found out from LOI study.
