BHL uses emerging technology purposefully to unlock collections, connect scientists with literature, connect literature with users, and connect users with other users. It ingests materials from various sources like the Internet Archive, Botanicus, and others. Subject headings are parsed and expressed as a tag cloud using MARCXML. The Google Maps API is used. Images are converted to text via OCR and names are found and submitted to NameBank. Images are displayed as JPEG2000 files for performance. BHL integrates with providers like Encyclopedia of Life, Atrium, and Wikipedia.
Este documento resume la ubicación de los 49 egresados del Magíster en Gestión para la Globalización del Ciclo 2007 que recibieron una beca de Minera Escondida. Indica que 7 estudian en Inglaterra, 18 en Estados Unidos repartidos entre escuelas en Rochester, Arizona y Florida, y 24 en Australia repartidos entre universidades en Melbourne, Sydney y Brisbane.
Este documento proporciona información sobre intercambios clínicos y de investigación organizados por la Federación Internacional de Asociaciones Médicas Estudiantiles (IFMSA). Detalla los plazos de inscripción, duración de los intercambios, cupos disponibles por país, proceso de postulación y costo. Los interesados deben llenar un formulario en línea luego de haber depositado $5000 y seleccionar tres países y ciudades de acuerdo a sus preferencias.
The document discusses enterprise architecture in academic environments. It begins by defining enterprise architecture and describing the practice of EA. It then discusses using EA as a strategy, with four operational models. It also briefly mentions applying EA in academia and the organization ITANA.org. Slides include definitions, frameworks, diagrams, and examples to illustrate concepts of EA.

This document discusses different ways that models can be structured and organized in Rails using acts_as_list, acts_as_tree, and acts_as_nested_set. Acts_as_list allows models to be organized and reordered as a simple list. Acts_as_tree allows models to be organized hierarchically with parent-child relationships like a tree. Acts_as_nested_set allows complex hierarchical relationships and includes additional methods for managing the tree structure.
This document provides an overview and details about the upcoming Rails 2.0 release. It mentions that a preview release is coming before release candidates and the final release. It also notes that release 1.2.4 will include bug fixes and deprecation warnings to help upgrade existing apps. The rest of the document outlines new features and changes for Rails 2.0 across Action Pack, Active Record, and other areas.
3. classの初歩と継承
# ただの名前と点数を表示するだけ s=Student.new("fujioka")
のプログラム s.english=80
s.puts_status
class Student rs=RikeiStudent.new("katahira")
attr_accessor :name rs.english=80
attr_accessor :english rs.math=92
def initialize(name) rs.science=85
@name=name rs.puts_status
end
def puts_status
puts @name
puts @english ~% ruby person.rb
end fujioka
end 80
katahira
class RikeiStudent < Student 80
92 解説ポイント
attr_accessor :math
attr_accessor :science 85
•継承
def puts_status
super •attr_accessor
puts @math •super
puts @science
end
•new
end •initialize
•ぐらい?
4. classの解説ちょっとだけ
class Student s=Student.new("fujioka")
@@namelist=[] s.english=80
attr_accessor :name s.puts_status
attr_accessor :english rs=RikeiStudent.new("katahira")
def initialize(name) rs.english=80
@name=name rs.math=92
解説ポイント
@@namelist.push name rs.science=85
end rs.puts_status •クラスメソッド
def puts_status p Student.namelist
puts @name p RikeiStudent.namelist •インスタンスメソッド
puts @english
end •クラス変数
def self.namelist •インスタンス変数
@@namelist % ruby person.rb
end fujioka •オブジェクトに型がある
end 80
katahira •変数に型はない
class RikeiStudent < Student 80
attr_accessor :math 92
attr_accessor :science 85
def puts_status ["fujioka", "katahira"]
super ["fujioka", "katahira"]
puts @math
puts @science
end
end
5. classの入れ子
class Sample
attr_accessor :value #<Sample:0x239ec>
KATAHIRA="DO" #<Sample::Sample2:0x23834>
class Sample2 "VALUE"
attr_accessor :value nil
def self.katahira "DO"
KATAHIRA
end
end
class Sample3
end
end
sample=Sample.new
p sample
sample2=Sample::Sample2.new
p sample2
sample.value="VALUE" 解説ポイント
p sample.value
p sample2.value •インスタンスものは独立している
p Sample::Sample2.katahira
•クラスものは子クラスから呼び出せる
7. moduleをちょっとだけ
module SampleModule
PI=3.14
def self.pi % ruby module.rb
PI 3.14
end 3.14
def pi
PI
end
end
p SampleModule.pi
class SampleClass
include SampleModule
end 解説ポイント
sc=SampleClass.new •moduleをクラスメソッドのように使う
p sc.pi
•self.piのようにすると呼び出せる
•moduleをmix-in用に使う
•includeするとclassのメソッドの一部になる
8. moduleを入れ子に
module SampleModule
module ChildModule
def child_module % ruby module_chile.rb
"CHILD_MODULE" "SAMPLE_MODULE"
end "CHILD_MODULE"
end
def sample_module
"SAMPLE_MODULE"
end
end
class SampleClass
include SampleModule
include ChildModule
end 解説ポイント
sc=SampleClass.new •同じネームスペースのものしかmix-inされない
p sc.sample_module
p sc.child_module •入れ子もincludeしなければならない
•Railsのソースはほとんどmoduleばっかり
•ちょっとだけ見てみよう
•ARの呼び出しの部分でも見てみるか。
