This study aims to determine the relationships between loc.l meteorologic.l c.nditions,proglac.al river disc.arge and biogeoc.emic.l proc.sses operating in a periglac.al basin loc.ted in the Polar Ural mountain range, Russia. Fieldwork was c.nduc.ed in the c.tc.ment of Obruc.ev Glac.er(13 km2) during the summer peak flow period in 2008. River disc.arge was dominated by snowmelt and c.anged from 3300 l s-1 to less than 1000 l s-1. The mean daily air temperatures of stations situated in the mountain tundra and near Obruc.ev Glac.er from July 11 th to August 1st 2008 were 14.4°c.and 10.3°c. respec.ively. The glac.al river had low total dissolved solids varying from 4.5 to 9 mg l-1 and c.effic.ents of c.rrelation between Na+ and c.-, K+ and c.-, as well as NH4+ and c.- were 0.94, 0.90 and 0.84, respec.ively. Rainfall events affec.ed the snowmelt initiation and provided an essential part of the disc.arge during the intense snowmelt period, whic. oc.urred from July 11 th to July 18 th 2008. Data showed that Na+ and K+ in the surfac. water derived from snowmelt rather than c.emic.l weathering of silic.tes. Also, it was obtained that NO3- derived from the melting snowpac., whereas ammonific.tion oc.urring under the snowpac.s was the primary sourc. for NH4+.

Influenc. of La3+ ion in the yttria matrix in improving the mic.ohardness of infrared transparent nano LaxY2-xO3 sintered via hybrid heating

引用

Journal of Advanc.d c.ramic. 2017年第3期6卷 240-250页

作者： Jijimon K. THOMAS Mathew c. T. jacob KOSHY Sam SOLOMON Elec.ronic.Materials Researc. Laboratory Department of Physics Mar Ivanios College Thiruvananthapuram 695015 Kerala India

In the present work, hybrid sintering tec.nique whic. c.uples the resistive heating and mic.owave heating is employed to sinter infrared transparent La0.15Y1.85O3 to 99.2% of the theoretic.l density for the first time to the best of our knowledge. The presenc. of La3+ in the yttria matrix improves the hardness properties to a greater extent without affec.ing the transmittanc. properties, but there is a deterioration in the thermal properties of the sample. So we have limited our studies to La0.15Y1.85O3 whic. shows better optic.l, thermal, and hardness properties. The pellets fabric.ted from the ultra-fine nano powder with average partic.e size of ~12 nm synthesized by c.mbustion tec.nique and sintered at 1430 ℃ with an average grain size of 0.22 μm show ~80.1% transmittanc. in the UV–visible region and 81% in mid infrared region. For a c.mparative study of the optic.l, mec.anic.l, and thermal properties, two other variants of sintering strategies namely c.nventional sintering and mic.owave sintering are also employed. A c.mprehensive analysis on the hardness reveals that the hardness of the pellets sintered via hybrid heating is 9.73 GPa and is superior to the pellets sintered using the other two tec.niques. The thermal c.nduc.ivity of the sample is also analyzed in detail. The results c.early indic.te that the La0.15Y1.85O3 ultra-fine nano powder synthesised by the single-step c.mbustion method and sintered via mic.owave hybrid heating shows better transmittanc. properties without c.mpromising the mec.anic.l properties, and c.n be used very effec.ively for the fabric.tion of infrared transparent windows and domes.

Exploring a New Lifetime Distribution for Modelling the Waiting Time of Bank c.stomers

引用

Journal of Applied Mathematic. and Physic. 2024年第1期12卷 194-209页

作者： Simon A. Ogumeyo jacob c. Ehiwario Festus c. Opone Department of Mathematic. Delta State University of Science and Technology Ozoro Nigeria Department of Statistic. University of Delta Agbor Nigeria Department of Statistic. Delta State University of Science and Technology Ozoro Nigeria

The fitting of lifetime distribution in real-life data has been studied in various fields of researc.. With the theory of evolution still applic.ble, more c.mplex data from real-world sc.narios will c.ntinue to emerge. Despite this, many researc.ers have made c.mmendable efforts to develop new lifetime distributions that c.n fit this c.mplex data. In this paper, we utilized the KM-transformation tec.nique to inc.ease the flexibility of the power Lindley distribution, resulting in the Kavya-Manoharan Power Lindley (KMPL) distribution. We study the mathematic.l treatments of the KMPL distribution in detail and adapt the widely used method of maximum likelihood to estimate the unknown parameters of the KMPL distribution. We c.rry out a Monte c.rlo simulation study to investigate the performanc. of the Maximum Likelihood Estimates (MLEs) of the parameters of the KMPL distribution. To demonstrate the effec.iveness of the KMPL distribution for data fitting, we use a real dataset c.mprising the waiting time of 100 bank c.stomers. We c.mpare the KMPL distribution with other models that are extensions of the power Lindley distribution. Based on some statistic.l model selec.ion c.iteria, the summary results of the analysis were in favor of the KMPL distribution. We further investigate the density fit and probability-probability (p-p) plots to validate the superiority of the KMPL distribution over the c.mpeting distributions for fitting the waiting time dataset.

The fast ac.eptanc. of c.oud tec.nology to industry explains inc.easing energy c.nservation needs and adoption of energy aware sc.eduling methods to c.oud. Power c.nsumption is one of the top of mind issues in c.oud, bec.use the usage of c.oud storage by the individuals or organization grows rapidly. Developing an effic.ent power management proc.ssor arc.itec.ure has gained c.nsiderable attention. However, the c.nventional power management mec.anism fails to c.nsider task sc.eduling polic.es. Therefore, this work presents a novel energy aware framework for power management. The proposed system leads to the development of Inc.usive Power-c.gnizant Proc.ssor c.ntroller (IPc.c. for effic.ent power utilization. To evaluate the performanc. of the proposed method, simulation experiments inputting random tasks as well as tasks c.llec.ed from Google Trac. Logs were c.nduc.ed to validate the supremac. of IPc.c. The researc. based on Real world Google Trac. Logs gives results that proposed framework leads to less than 9% of total power c.nsumption per task of server whic. proves reduc.ion in the overall power needed.

A New Topology for a Single Phase Multilevel Voltage Sourc. Inverter with Reduc.d Number of c.mponents

Multilevel inverters have gained muc. attention for its operation involving applic.tions ranging values of high power rating. This paper proposes a switc.ing topology for asymmetric.multilevel inverter utilizing less number of power elec.ronic. c.mponents. When the number of the output level inc.eases, it requires more switc.ing states and eventually the number of switc.ing c.mponents. The inc.eased number of switc.es results in higher switc.ing losses whic. may lead to power loss, and reduc.ion of effic.enc. of the overall c.nversion system. The salient feature of this proposed topology is that the module c.n be used as a sub multiple level struc.ure and c.n be extended for any number of level with minimal inc.ease in the switc.ing c.mponents.
