Abstract: Security plays a principal role in every part of internet services like E- Mail, E-Banking etc. Android appliances are becoming trendy in today’s world. Pattern toning is used to provide security in all android phones. The employ of ciphers is known to be primordial. Cipher can be easily predictable by shoulder-surfing attack and guessing attacks, which stimulates the system to go out of order leading to timorous login. It can send unsolicited mails and reconnoiter all the personal minutiae. It is perilous to all cyberspace services. A new pel based secure corroboration is proposed to overture security by overcoming the sundry cipher attacks. The objective of the paper is to render impregnable corroboration in the field of wireless android mobile communication by customary login and encipher login. The encipher login is achieved by scheming the codes corresponding to the typescript of password based on which it is calibrated to a set of portraits. In the interim of registration, the ultimate user should elect any two metaphors from the rendered snapshot and then select a pel in each selected portrait. During login, username, cipher, metaphor and pel selection will vanguard to secure corroboration.

During the past twenty years Open Educational Resources (OER) and Open Educational Practices (OEP) have increased educational access and affordability worldwide. The OER-OEP synergy reflects one of the most promising strategies for increasing access to education globally. Despite significant progress, emerging research suggests the need for a more concerted focus on moving from awareness raising to implementation. This article analyses the current status of OER and OEP in concert with the recent educational response to COVID-19 by educational providers with complimentary mini-case studies from Africa, Brazil, Canada, China, Sweden, and Turkey. The ICDE Ambassadors for the global advocacy of OER, and members of ICDE OER Advocacy Committee (authors) argue that in the six countries studied, there is a greater need and greater receptivity to expand access to education through OER and OEP. To better address the immediate needs of the COVID-19 educational crisis, and to make longer term educational improvements, countries should harness the policy supports and actionable steps offered by the UNESCO OER Recommendation. Currently, we see an opportunity to move OER-OEP to resilient sustainable education and the international policy framework to support such work. The article concludes with some general observations for the way forward.

For the South polar lunar region between −85 and −90° Latitude an updated analyses of the solar illumination and ground station visibility conditions has been performed in the frame of a feasibility study for an ESA Lunar Lander mission. The analyses are based on the refined lunar digital elevation model provided by the Japanese Kaguya/Selene mission, originating from its LASER altimeter instrument. For the South polar region maps of integral solar illumination are presented for a mission epoch in 2016. The analysis modelling was validated with the help of a Kaguya High Definition video. The solar illumination is driving for the power subsystems of any robotic lander craft or manned lunar outpost, in case they rely on conventional photovoltaic power generation with battery buffering of shadowed periods. In addition the visibility of the terrain from a terrestrial ESA ground station was analysed. The results are presented as an integral ground contact duration map, being crucial for ...
