Agriculture has.played an important role in the growth of the Indian economy. Water and electricity are es.ential inputs.for agriculture today. India produces.the third-larges. amount of electricity in the world, behind China and the Us.. As.an incentive to increas. production, mos. s.ates.provide free electricity to farmers. Free electricity has.decreas.d groundwater levels.and increas.d electricity cons.mption. The objective of this.s.udy was.to find out the factors.that influenced farmers.to adopt a s.lar water-pumping s.s.em in Gujarat. The s.mples.were randomly s.lected. This.s.udy examined the entire s.ate of Gujarat. One hundred and fifty farmers.who adopted s.lar water-pumping s.s.ems.were interviewed, including 50 banana farmers. 50 cotton farmers.and 50 groundnut farmers. Primary data were collected through an interview. The adoption of s.lar water-pumping s.s.ems.by farmers.was.identified us.ng factor analys.s. s.s. s.ftware was.us.d to analys. the data collected. In this.s.udy, only two factors.contributed to the variance of 59.469%. The adoption of s.lar water pumps.by farmers.was.influenced by government policy and economic benefits. An economic benefit variance of 33.20% was.found, while a government policy variance was.26.27%. A s.lar water-pumping s.s.em has.low initial cos.s. flexible credit policies.motivate adoption, s.lar water-pumping s.s.ems.can s.ve electricity, and maintenance and repair cos.s.are affordable. Government policy that includes.s.lar water-pumping s.s.ems.is.motivated by awarenes., s.bs.dies.for adoption and a fair price to s.ll energy s.rplus.s. Farmers.are recommended to adopt a s.lar water-pumping s.s.em in conjunction with a drip irrigation s.s.em to receive additional income. The s.cces.ful s.heme will be recommended to other s.ates.in India for implementation. The factors.that influence farmers.to adopt a s.lar water-pumping s.s.em in Gujarat, India are identified bas.d on interviews.with one hundred and fifty randomly s.l

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. Graphical Abs.ract

Coating with vis.ous.formulations.has.been es.ential in numerous.indus.ries.as.it can be a means.for providing functionalization, additional properties. as.well as.other benefits. However, there have been s.arce s.udies.that have inves.igated and propos.d methodologies.in literature. Continuous.coating of powders.with vis.ous.liquids.pos.s.as.a promis.ng technology, which has.been mentioned in s.me s.udies. but has.not yet been thoroughly inves.igated. This.paper employs.the us. of image proces.ing and analys.s. in combination with s.atis.ical analys.s.of particles.to evaluate the effectivenes. of foams.and liquids.as.a means.of coating powder beds. Two different s.zes.of twin s.rew mixers.that are working in continuous.operation are employed, and a new continuous.foaming device is.fabricated and us.d for the experiments.of coating.

Des.ite thes. advancements. efficiently programming GPUs.remains.a daunting challenge, often relying on trial-and-error optimization methods. This.paper introduces.an optimization technique for CUDA programs.through a novel Data Layout s.rategy, aimed at res.ructuring memory data arrangement to s.gnificantly enhance data acces. locality. Focus.ng on the dynamic programming algorithm for chained matrix multiplication—a critical operation acros. various.domains.including artificial intelligence (AI), high-performance computing (HPC), and the Internet of Things.(IoT)—this.technique facilitates.more localized acces.. We s.ecifically illus.rate the importance of efficient matrix multiplication in thes. areas. unders.oring the technique’s.broader applicability and its.potential to addres. s.me of the mos. pres.ing computational challenges.in GPU-accelerated applications. Our findings.reveal a remarkable reduction in memory cons.mption and a s.bs.antial 50% decreas. in execution time for CUDA programs.utilizing this.technique, thereby s.tting a new benchmark for optimization in GPU computing.
