The spacing effect describes the robust phenomenon whereby memory is enhanced when learning events are distributed, instead of being presented in succession. We investigated the effect of spacing on children's memory and category induction. Three-year-old children were presented with two tasks, a memory task and a category induction task. In the memory task, identical instances of an object wer...

In the previous two chapters we have assumed our systems to be ideal without any interchannel interference. In this chapter we analyze the effects of interchannel interference on the performance of the receiver. The model assumed is that of rectangular spectra with spacing of channels less than channel width so that there is some overlap. It is shown that some overlap in the system is acceptabl...

An analytical framework is established to dimension the pilot grid for MIMO-OFDM operating in time-variant frequency selective channels. The optimum placement of pilot symbols in terms of overhead and power allocation is identified that maximizes the training-based capacity for MIMO-OFDM schemes without channel knowledge at the transmitter. For pilot-aided channel estimation (PACE) with perfect...

Nitrogen is the most important nutrient to plant, and its dose depends on amount, availability plant density. This study was conducted in 20 September 2021 end of year, investigate effect nitrogen fertilizer spacing Okra Abelmoschus esculanntus (L.) Moennch vegetative growth pod characters. The treatments were laid out as factorial arrangement a Split Randomized Blocked Design, replicated four ...

This paper presents ongoing research in improvement of analytical tools for the characterization of rock mass structure from oriented borehole discontinuity data. Using automated multivariate cluster analysis and the “three dimensional stereonet” provides for fast and objective characterization of oriented core discontinuity data. Improvements to the CYL software include three new methods of cl...

L. Kuchariková, E. Tillová, J. Belan, M. Chalupová, A. Vaško, I. Švecová, University of Žilina, Faculty of Mechanical Engineering, Slovakia The present work deals with evaluation of eutectic Si (its shape, size, and distribution), dendrite cell size and dendrite arm spacing in aluminium cast alloys which were cast into different moulds (sand and metallic). Structural parameters were evaluated u...

The variation of circular microstrip antenna, a Sectoral microstrip antenna is discussed. The detail analysis to study the effects of antenna parameters like, feed point location and the substrate thickness for Sectoral angle increasing from 270 to 340 on the patch first four resonant modes is presented. The variation in angle tunes the spacing between three patch resonant modes which yields op...

Background Jampersal (jaminan persalinan or insurance for delivery) is one of the programmes of the Ministry of Health to accelerate the MDG’s 4 and 5 to eliminate financial barriers and increase access to safe health and delivery, high quality and affordable cares. Jampersal service package includes antenatal care, childbirth, postnatal care, and family planning. It is also expected that birth...

CO 2 Plume Geothermal (CPG) energy systems circulate geologically stored to extract geothermal heat from naturally permeable sedimentary basins. CPG can generate more electricity than brine in geologic reservoirs with moderate temperature and permeability. Here, we numerically simulate the depletion of a basin find corresponding generation variation over time. We that for given reservoir depth,...
