Comparing several heuristics for a packing problem

Packing problems are in general NP-hard, even for simple cases. Since now there are no highly efficient algorithms available for solving packing problems. The two-dimensional bin packing problem is about packing all given rectangular items, into a minimum size rectangular bin, without overlapping. The restriction is that the items cannot be rotated. The current paper is comparing a greedy algorithm with a hybrid genetic algorithm in order to see which technique is better for the given problem. The algorithms are tested on different sizes data.Comment: 5 figures, 2 tables; accepted: International Journal of Advanced Intelligence Paradigm

Attenuation of the Ganglion Cell Layer in a Premature Infant Revealed with Handheld Spectral Domain Optical Coherence Tomography

Purpose: To report on subclinical retinal abnormalities shown through handheld spectral domain optical coherence tomography on a premature infant. Methods: Case report. Results: The initial and follow-up exams on a premature infant revealed severely attenuated ganglion cell and nerve fiber layers. There was cystoid macular edema in both eyes at the initial visits, which resolved by the 1-year follow-up. Discussion: Optical coherence tomography can reveal significant retinal abnormalities in premature infants which are not detectable through funduscopic exam. Documenting such findings may be useful for the comprehensive management of vision problems in children with a history of premature birth

FLARR Pages #39: Perceptions of Foreign Language Education in the Rural High School

This study was conducted by the foreign language instructor of a rural school district in Northwestern Minnesota. The population of the high school (grades nine through twelve) is 144 students. The racial composition of the district is nearly 100% white. The district is classified as low-income with 41.3% of the district\u27s children qualifying for free or reduced hot lunch. Of the most recent three classes, an average of 39% of graduates planned to attend a four-year college, 37% planned to attend a two-year college, and 24% planned to enter the work force. This study evolved from the observation by the researcher that foreign language study was perceived by some as unnecessary, impractical or even frivolous. Some students, parents and even faculty did not see foreign language as a necessity in high school education. The goal of the study was three-fold: to investigate the beliefs and attitudes toward foreign language study in the community, to try to determine why these beliefs existed, and to investigate how foreign language can better be promoted as an important course of study for all students. An important note is that Spanish is the only foreign language offered to the students of the district. This may affect the student\u27s choice to study foreign language, if the student would have preferred a different language, for example

The Chambers of the Sea and a Knock Upon the Door : Questioning Meaning in T.S. Eliot’s The Love Song of J. Alfred Prufrock and The Waste Land

T.S. Eliot is an undeniably prominent figure in the Modernist poetry movement. Not only was he greatly influenced by his contemporaries but he was also a notable literary figure himself. To this day, he is regarded as an eminent voice for his war-torn generation. Considered by many to be Eliot’s finest works both “The Love Song of J. Alfred Prufrock” and “The Waste Land” present broken thoughts, images, and allusions to the past, all fused together to reveal the disintegration of the modern world. This paper explores how The Wasteland” differs from “The Love Song of J. Alfred Prufrock” in that though the speakers in both poems are searching, Prufrock’s journey ends in definite pessimism while the speaker in “The Waste Land” is left still searching
