Effects of elevated temperatures on the thermal behavior and mechanical performance of fly ash geopolymer paste, mortar and lightweight concrete
(Elsevier, 2014-01)
This paper reports a comparative study of the influence of elevated temperature on geopolymer paste, mortars and lightweight aggregate geopolymer concrete (LWAGC) systems made by using fly ash (FA) as only source material. ...
Linearity improvement of 5.2-GHz CMOS up-conversion mixer for wireless applications
(John Wiley & Sons, Inc., 2012-04)
This letter presents linearity improvement up-conversion mixer at 5.2 GHz for wireless applications. The design is based on Gilbert-cell active double-balanced mixer using derivative superposition method for linearity ...
Design and Analysis of XOR Logic Gate Based on Two-Photon Absorption
(EDP Sciences, 2016)
Two-photon absorption with high intensity pump beam occurs in a SOA depends on fast phase change of a weak probe signal. This work analysed optical XOR logic function using two-photon absorption induced fast phase change. ...
Smart Rash Driver System via Internet of Things (IoT)
(EDP Sciences, 2017)
Nearly half a million accidents on Malaysians road occur in 2015. The aim of this research is to detect car speed, capture the photo of the speeding car and then transfer the data like car speed, date and time, location ...
High performance systolic array core architecture design for DNA sequencer
(EDP Sciences, 2018)
This paper presents a high performance systolic array (SA) core architecture design for Deoxyribonucleic Acid (DNA) sequencer. The core implements the affine gap penalty score Smith-Waterman (SW) algorithm. This time-consuming ...
