This study aims to determine the inflectional morpheme contained in short story entitled "The Child's Story" by Charles Dickens. The analysis shows that there are 108 morphemes found Story". There 35 plural nouns “-s”, “-es” with 32.5% percentage as most dominant this story. Next, possessive “-'s”, “-s'” and comparative adjectives “-er” both show 2 data (1.8%), superlative “-est” 3 (2.7%), 3rd ...

Scanning Electro n Mic roscopy (SEM) and X· ray Mic ro· analys is (EOS) have been used to investigate product conwinc r interaction problems in plai n tinplate metal food containers and to examine glass and glass-like particles that we re found in canned food . Through the usc o f SEMEDS. it wa~ detemlined that: sulfa te contain ing panicles from the cannery cooling water reacted with exposed i...

With continuous scaling down of the semiconductor technology, the soft errors induced by energetic particles have become an increasing challenge in designing current and next-generation reliable microprocessors. Due to their large share of the transistor budget and die area, cache memories suffer from an increasing vulnerability against soft errors. Previous work based on the vulnerability fact...

Separating codes, initially introduced to test au tomaton , have revived lately in t h e s t u d y of f ingerprint ing codes, which are used for copyr ight protect ion. Separating codes play the i r role i n making t h e fiugerpr in t ing scheme secu re agains coalitions of pirates. We provide h e r e better bounds o n such codes.

Problems which Induce performance that has the fa lse appearance of success (garden path problems) may be an I n e v i t a b l e consequence of the need ( I n both human and computer problem so lv ing systems) to create abs t rac t knowledge representat ions In order to make problem so lv ing e f f i c i e n t . An example is presented from s domain of physics problem so lv ing tasks in which a...

3-D virtual worlds are increasing in popularity as a medium for higher education. In this research, we assess the efficacy of two instruction strategies in a virtual world environment, Second Life, and their effects on interactivity, social presence, and perceived learning. The two instruction strategies are direct and interactive instruction strategies. Our findings suggest that the interactiv...
