We review the study on a two-way quantum key distribution protocol given imperfect settings through a simple analysis of a toy model and show that it can outperform a BB84 setup. We provide the sufficient condition for this as a ratio of optimal intensities for the protocols.This article appeared in a journal published by Elsevier. The attached cop
Introduction. "Waterfront‟ in the context of towns and cities deals with the areas that are in direct contact with the water bodies. Malaysia‟s Department of Drainage and Irrigation defines the waterfront development as area within 50m or two lots of building from the banks (JPS, 2003)where the water is visually noticeable.

Solar radiation sensor is a device that is used to measure solar radiation in W/m^2. Determining the solar radiation and its interaction with the atmosphere and the earth's surface is important because atmospheric circulation is driven by solar radiation. Moreover, solar radiation accounts for almost all of the energy available to the earth. Th
Unforeseen attacks on ICT systems incurred billions of dollars of losses to public and private communities. The current parametric encryption algorithms suffer the unconventional and paranormal attacks. A search for a new paradigm against the unforeseen and paranormal attacks lead to an invention called Unique Class Encryption (UCE) that is based o
People with dementia brain (DBrain) have acquired global impairments of the intellect, memory and personality. In Malaysia alone there are estimated 100,000 sufferers of dementia. Presently about 26.6 million people worldwide have dementia related diseases. By 2020, this is expected to rise to 34 million and 104 million by 2050.. The development of
