Rank-1 Matrix Approximation-Based Channel Estimation for Intelligent Reflecting Surface-Aided Multi-User MISO Communications

Unknown author [Article-Full-text]

The acquisition of channel state information is an essential step in enabling intelligent reflecting surfaces (IRSs) for wireless communications. In this letter, we introduce a novel procedure to estimate the cascaded ...
Ranking of walling materials using eco-efficiency for tropical climatic conditions: A survey-based approach

Gurupatham, S.V.; Jayasinghe, C.; Perera, P. [Article-Full-text]

All over the world, “Construction” is an important sector that consumes a significant amount of resources and produces a lot of waste. Buildings as a whole share nearly one-fourth of total electricity generation in tropical ...
Rapid seismic visual screen method for masonry infilled reinforced concrete framed buildings: Application to typical Sri Lankan school buildings

Sathurshan, M; Thamboo, J; Mallikarachchi, C; Wijesundara, K; Dias, P [Article-Full-text]

Seismic rapid visual screening (RVS) methods are used when a large stock of structures is to be evaluated for seismic risk. Although several RVS methods are available, applications of those methods to appraise the seismic ...
Ratio based indicators and continuous score functions for better assessment of building sustainability

Chandratilake, SR; Dias, WPS [Article-Full-text]

A sustainability assessment scheme for buildings is proposed with two key features, namely the use of quantifiable indicators rather than subjective scores for aspects; and the use of continuous functions for the indicator ...
A rational design of high efficient and low-cost dye sensitizer with exceptional absorptions: Computational study of cyanidin based organic sensitizer

Galappaththi, K; Ekanayake, P; Petra, MI [Article-Full-text]

Real-time light field denoising using a novel linear 4-D hyperfan filter

Premaratne, SU; Liyanage, N; Edussooriya, CUS; Wijenayake, C [Article-Full-text]

Four-dimensional (4-D) light fields (LFs) enable novel imaging technologies, which are traditionally based on two-dimensional images. In most of these applications, denoising of LFs is required as a preprocessing technique ...
Real-time light field signal processing using 4D/5D linear digital filter FPGA circuits

Edussooriya, CUS; Wijenayake, C; Madanayake, A; Liyanage, N; Premaratne, S; Vorhies, JT; Dansereau, DG; Agathoklis, P; Bruton, LT [Article-Full-text]

Light fields (LFs) and light field videos (LFVs) capture both angular and spatial variation of light rays emanating from scenes. This richness of information leads to novel applications such as post-capture refocusing, ...
Recent investigations on the evaluation of solar PV hosting capacity in LV distribution networks constrained by voltage rise

Chathurangi, D.; Jayatunga, U.; Perera, S [Article-Full-text]

Evaluation of the maximum connected solar photovoltaic (PV) capacity without violating stipulated network voltage limits is essential in managing the voltage rise in low-voltage (LV) networks under increasing solar penetration ...
Reconfigurable Intelligent Surface Assisted Two-Way Communications: Performance Analysis and Optimization

Atapattu, S; Fan, R; Dharmawansa, P; Wang, G; Evans, J; Tsiftsis, TA [Article-Full-text]

In this paper, we investigate the two-way communication between two users assisted by a reconfigurable intelligent surface (RIS). The scheme that two users communicate simultaneously over Rayleigh fading channels is ...
Reconstruction of the upper gondwana palaeoclimates based on palynostratigraphy, palynofacies and sedimentology of the Jurassic sequences in the Tabbowa Basin, Sri Lanka

Weerakoon, WAP; Aggarwal, N; Jha, N; Jayasena, HAH; Joshi, H; Yakandawala, D; Chandrajith, R; Perera, KVGS; Ratnayake, NP [Article-Full-text]

The palynological study of the Tabbowa sediments from Sri Lanka reveals predominant Jurassic gymnospermous pollen assemblage (Araucariacites australis, A. cooksonii, A. fissus and Callialasporites dampieri with spore ...
Reducing CO2 level in the indoor urban built environment: Analysing indoor plants under different light levels

Weerasinghe, N. H; Silva, P. K.; Jayasinghe, R. R.; Abeyrathna, W. P.; John, G. K. P.; Halwatura, R. U. [Article-Full-text]

Recent studies have highlighted that people spend most of their time indoors, making indoor air quality a critical concern. Indoor air pollution can have detrimental effects on human health, and the concentration of carbon ...
Reducing surface roughness by varying aerosol temperature with minimum quantity lubrication in machining AISI P20 and D2 steels

Senevirathne, SWMAI; Punchihewa, HKG

Heat generation in metal cutting leads to numerous problems. Despite the development of many different cooling and lubrication methods in industry, opportunities are still open to develop novel methods. Minimum quantity ...
Reducing work-related Musculoskeletal Disorders (MSDs) through design: Views of ergonomics and design practitioners

Punchihewa, HKG; Gyi, DE [Article-Full-text]

BACKGROUND:Work-related Musculoskeletal Disorders (MSDs) affect the well-being ofworkers. Unfortunately, user requirements for design to reduce workplace risk factors for MSDs are not always effectively communicated to ...
Reduction of concrete sorptivity with age through carbonation

Dias, WPS [Article-Full-text]

Ordinary Portland cement (OPC) concrete specimens that had been air - dried for 3.5 years were found to have an increase in weight and reduction in sorptivity, with weight and sorptivity changes being greater for specimens ...
Reduction of fibrillar strain-rate sensitivity in steroid-induced osteoporosis linked to changes in mineralized fibrillar nanostructure
