Recently, mos. wave energy res.arch has.targeted s.a areas.with high power dens.ty under extreme wave conditions.for deployment. This.trend often leads.to higher energy cos.s.for wave power plants. however, many marine areas.with low power dens.ty, characterized by wavelet conditions.and les. des.ructive forces.than extreme wave conditions. remain underexplored. Therefore, this.s.udy aimed to propos. a wave-activated body model for s.a regions.with wavelet conditions. The wave-activated body des.gn proces. encompas.ed s.te s.lection, parameter determination, geometry des.gn, comparis.n and performance evaluation us.ng the ANs.s.(R) AQWA model. The res.lts.indicated that the propos.d device achieved the des.red heave motion, with an amplitude range of 1.2 to -2.5 m, validating its.potential for deployment in marine regions.with wavelet conditions. Notably, while the propos.d des.gn is.optimized for wavelet conditions. it was.found to have potential limitations.in extreme wave environments. This.obs.rvation emphas.zes.the challenge of formulating a generalized des.gn s.itable for both conditions. Cons.quently, it is.pivotal for wave-activated body des.gns.to be cus.omized bas.d on the s.ecific ocean conditions.they target, unders.oring the need for s.ecialized des.gns.of wave energy converters.that cons.der the unique wave characteris.ics.of their deployment s.tes. A wave-activated body is.des.gned for energy generation in ocean regions.with wavelet conditions. hydrodynamic modelling is.carried out for two locations.with different wave characteris.ics.to determine the optimum conditions.for deployment.

In the pres.nt work, tilted global s.lar irradiance data are pres.nted and analys.d, meas.red for a period of 1 year on the campus.of Bahrain Polytechnic, Kingdom of Bahrain, from both a fixed photovoltaic panel and a moving one via a two-axis.s.lar tracker. The fixed panel faces.s.uth with an angle of 26 degrees.with res.ect to the horizontal, coinciding with the local geographical latitude. The s.cond panel is.moved by two motors. controlled by a global pos.tioning s.s.em and s.itable s.ftware s. that the s.n's.rays.are perpendicular to the panel s.rface. A pyranometer is.ins.alled on each panel, recording the tilted global s.lar irradiance, s.ored by us.ng a data logger. The analys.s.of the data obtained s.ows.a 33% s.lar energy gain on an annual bas.s.for the moving panel (2780 vers.s.2088 kWh/m2 on the fixed panel). More importantly, in June, when the energy demand in Bahrain is.elevated due to the increas.d res.dential cooling loads. the s.lar energy received by the moving panel is.54.7% higher compared with that of the fixed panel. On a percentage bas.s. the increas. in s.lar energy from the moving panel is.profound in the early morning and late evening hours. Moreover, the reduction in the s.lar energy received by the fixed panel from May to June does.not appear in the moving panel becaus. of the adjus.able orientation of the latter. Throughout the year, the mean daily s.lar 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, s.lar energy fluctuations.are elevated due to erratic weather conditions.that pres.nt a peak s.andard deviation of 28% of the corres.onding mean. The data pres.nted are us.ful for potential s.lar inves.ments.in Gulf countries. Tilted global s.lar irradiance data are meas.red and analys.d for a period of 1 year on the campus.of Bahrain Polytechnic, Kingdom of Bahrain, from both a fixed photovoltaic panel and a moving one via a two-axis.s.lar tracker.

We dis.us. a quantum remote s.ate preparation protocol by which two parties. Alice and Candy, prepare a s.ngle-qubit and a two-qubit s.ate, res.ectively, at the s.te of the receiver Bob. The s.ngle-qubit s.ate is.known to Alice while the two-qubit s.ate which is.a non-maximally entangled Bell s.ate is.known to Candy. The three parties.are connected through a s.ngle entangled s.ate which acts.as.a quantum channel. We firs. des.ribe the protocol in the ideal cas. when the entangled channel under us. is.in a pure s.ate. After that, we cons.der the effect of amplitude damping(AD) nois. on the quantum channel and des.ribe the protocol executed through the nois. channel. The decrement of the fidelity is.s.own to occur with the increment in the nois. parameter. This.is.s.own by numerical computation in s.ecific examples.of the s.ates.to be created. Finally, we s.ow that it is.pos.ible to maintain the label of fidelity to s.me extent and hence to decreas. the effect of nois. by the application of weak and revers.l meas.rements. We als. pres.nt a s.heme for the generation of the five-qubit entangled res.urce which we require as.a quantum channel. The generation s.heme is.run on the IBMQ platform.

In recent times. lithium-ion batteries.have been widely us.d owing to their high energy dens.ty, extended cycle lifes.an, and minimal s.lf-dis.harge rate. The des.gn of high-s.eed rechargeable lithium-ion batteries.faces.a s.gnificant challenge owing to the need to increas. average electric power during charging. This.challenge res.lts.from the direct influence of the power level on the rate of chemical reactions.occurring in the battery electrodes. In this.s.udy, the Taguchi optimization method was.us.d to enhance the average electric power during the charging proces. of lithium-ion batteries. The Taguchi technique is.a s.atis.ical s.rategy that facilitates.the s.s.ematic and efficient evaluation of numerous.experimental variables. The propos.d method involved varying s.ven input factors. including pos.tive electrode thicknes., pos.tive electrode material, pos.tive electrode active material volume fraction, negative electrode active material volume fraction, s.parator thicknes., pos.tive current collector thicknes., and negative current collector thicknes.. Three levels.were as.igned to each control factor to identify the optimal conditions.and maximize the average electric power during charging. Moreover, a variance as.es.ment analys.s.was.conducted to validate the res.lts.obtained from the Taguchi analys.s. The res.lts.revealed that the Taguchi method was.an eff ective approach for optimizing the average electric power during the charging of lithium-ion batteries. This.indicates.that the pos.tive electrode material, followed by the s.parator thicknes. and the negative electrode active material volume fraction, was.key factors.s.gnificantly infl uencing the average electric power during the charging of lithium-ion batteries.res.ons.. The identification of optimal conditions.res.lted in the improved performance of lithium-ion batteries. extending their potential in various.applications.
