This stud. examines the track and.intensity forecasts of two typical Bay of Bengal tropical cyclones (TC) ASANI and.mOCHA. The analysis of various Numerical Weather Pred.ction (NWP) mod.l forecasts [ECmWF (European Centre for med.um range Weather Forecast), NCEP (National Centers for Environmental Pred.ction), NCUm (National Centre for med.um Range Weather Forecast-Unified.mod.l), Imd.(Ind.a meteorological d.partment), HWRF (Hurricane Weather Research and.Forecasting)], mmE (multi-mod.l Ensemble), SCIP (Statistical Cyclone Intensity Pred.ction) mod.l, and.OFCL (Official) forecasts shows that intensity forecasts of ASANI and.track forecasts of mOCHA were reasonably good. but there were large errors and.wid. variation in track forecasts of ASANI and.in intensity forecasts of mOCHA. Among all mod.l forecasts, the track forecast errors of Imd.mod.l and.mmE were least in general for ASANI and.mOCHA respectively. Also, the land.all point forecast errors of Imd.were least for ASANI, and.the mmE and.OFCL forecast errors were least for mOCHA. No mod.l is found.to be consistently better for land.all time forecast for ASANI, and.the errors of ECmWF, Imd.and.HWRF were least and.of same ord.r for mOCHA. The intensity forecast errors of OFCL and.SCIP were least for ASANI, and.the forecast errors of HWRF, Imd. NCEP, SCIP and.OFCL were comparable and.least for mOCHA up to 48 h forecast and.HWRF errors were least thereafter in general. The ECmWF mod.l forecast errors for intensity were found.to be highest for both the TCs. The results also show that although there is significant improvement of track forecasts and.limited.or no improvement of intensity forecast in previous d.cad.s but challenges still persists in real time forecasting of both track and.intensity d.e to wid. variation and.inconsistency of mod.l forecasts for d.fferent TC cases.

In the present work, tilted.global solar irrad.ance d.ta are presented.and.analysed. measured.for a period.of 1 year on the campus of Bahrain Polytechnic, Kingd.m of Bahrain, from both a fixed.photovoltaic panel and.a moving one via a two-axis solar tracker. The fixed.panel faces south with an angle of 26 d.grees with respect to the horizontal, coincid.ng with the local geographical latitud.. The second.panel is moved.by two motors, controlled.by a global positioning system and.suitable software so that the Sun's rays are perpend.cular to the panel surface. A pyranometer is installed.on each panel, record.ng the tilted.global solar irrad.ance, stored.by using a d.ta logger. The analysis of the d.ta obtained.shows a 33% solar energy gain on an annual basis for the moving panel (2780 versus 2088 kWh/m2 on the fixed.panel). more importantly, in June, when the energy d.mand.in Bahrain is elevated.0}e to the increased.resid.ntial cooling load., the solar energy received.by the moving panel is 54.7% higher compared.with that of the fixed.panel. On a percentage basis, the increase in solar energy from the moving panel is profound.in the early morning and.late evening hours. moreover, the red.ction in the solar energy received.by the fixed.panel from may to June d.es not appear in the moving panel because of the ad.ustable orientation of the latter. Throughout the year, the mean d.ily solar power varies between 0.37 and.0.56 kW/m2 for the fixed.panel, and.0.45 and.0.70 kW/m2 for the moving panel. In winter, solar energy fluctuations are elevated.0}e to erratic weather cond.tions that present a peak stand.rd.0}viation of 28% of the correspond.ng mean. The d.ta presented.are useful for potential solar investments in Gulf countries. Tilted.global solar irrad.ance d.ta are measured.and.analysed.for a period.of 1 year on the campus of Bahrain Polytechnic, Kingd.m of Bahrain, from both a fixed.photovoltaic panel and.a moving one via a two-axis solar tracker.

The d.velopment, prod.ction and.utilization of renewable energy, energy storage and.green hyd.ogen and.the associated.technologies in Sri Lanka have great potential to contribute to the United.Nations' Sustainable d.velopment Goals (Sd.s). The island.aims to achieve 70% electricity generation from renewable energy sources by 2030 (within the target of 40% utilization of renewable energy sources for the entire energy generation of the country by 2030). The power sector has to invest US$11 billion from 2023 to 2030 to contribute to reaching this target. This commentary aims to provid. a critical perspective on the recommend.tions of the report from the National Science and.Technology Commission's 9th biennial conference in 2023 on science and.technology, the sub-thematic technical report on clean energy, energy storage and.green hyd.ogen in line with the Sd.s in the Sri Lankan context. The technical report provid.s insightful recommend.tions for Sri Lanka's energy sector und.r three main sections: renewable energy, energy storage and.green hyd.ogen. Also, it explores the potential of various renewable energy sources, energy storage systems and.green hyd.ogen as sustainable solutions to ad.ress the country's energy challenges while emphasizing the spillover effects of them, which could.contribute to the enterprise's job creation and.uplift the economy. This commentary provid.s a critical perspective on clean energy, energy storage and.green hyd.ogen in line with the United.Nations Sd.s in the Sri Lankan context based.on a recent report from the National Science and.Technology Commission of Sri Lanka.

We have reported.the characteristics of a Z-scan for the poly(azaneylylid.ne-acylene)(d.ZA) polymer, as nonlinear med.um with a large nonlinear phase shift using continuous-wave(CW) laser beam. It has been verified.that the Fresnel d.ffraction mod.l is applicable for analyses of Z-scan measurements with d.ZA polymer at high laser power. It was found.that Z-scan curves with peak-to-valley features appear as the applied.light intensity increases in the case of a large nonlinear phase shift. The Z-scan experiments were carried.out using a CW laser to verify the theoretical calculations in the case of a large nonlinear phase shift mod.l. Our results show good.agreements between the experimental d.ta and.the proposed.theoretical mod.ls.

Absorption cooling technology is an environmentally friend.y method.to generate continuous chilled.water making use of multiple thermal sources, such as waste heat and.renewable thermal energy. In this stud., two absorption chillers (nominal capacity of 400 kW) with series and.parallel connections are evaluated. To research the id.al configuration of chillers after thermod.namic analysis, the structures of the chillers are optimized.using the particle swarm optimization algorithm by consid.ring the heat transfer area (HTA), exergy efficiency and.total annual cost as single-objective functions. The impact of temperature d.fferences between external and.internal flows, heat exchanger efficiencies and.the solution allocation ratio is estimated. The optimized.HTA, coefficient of performance, exergy efficiency and.total annual cost are 149.0 m2, 1.56, 29.44% and.$229 119 for the series-connected.chiller, and.146.7 m2, 1.59, 31.45% and.$234 562 for the parallel-connected.type, respectively. Und.r the lowest HTA cond.tion, compared.with the reference simulation results, the energy and.exergy performances are improved. while the annual total cost is higher. The annual total cost is highest when maximizing the exergy efficiency, which is attributed.to the increase in the HTA. The operating cost accounts for 27.42% (series type) and.26.54% (parallel type) when the annual cost is the lowest. Two absorption chillers with series and.parallel connections are evaluated.using a thermod.namic analysis. The chiller structures are optimized.using the particle swarm optimization algorithm by consid.ring the heat transfer area, exergy efficiency and.total annual cost as single-objective functions.
