Here's what I have so far, but I want to remove the Windows Forms references. Any ideas? public delegate void SafeInvokeDelegate(System.Action action); public class SafeInvoke { private readonly System.Windows.Forms.Control _threadControl; public SafeInvoke() { _threadControl = new System.Windows.Forms.Control(); } public void Invoke(System.Action

1. 打开Web of Science www.webofknowledge.com 2. 选择数据库大类：Web of Science核心合集； 即CPCI（ISTP）和SCI已合并到web of science。 以检索PRICAI 2016会议为例，通过检索DOI 10.1007/978-3-319-42911-3 可以找到会议集的全部论文，包括53篇regular papers 和 15 篇short papers，且检索记录都是在WebofScience核心合集当中。 ISI和ISIP并不是区分期刊和会议的标准，PRICAI 2016会议论文的Unique ID以ISI开头，且IDS为BG4TJ。 如果是期刊想确保是SCI的话，最好去ISI检索确认: ISI官方: http://scientific.thomson.com/mjl/ http://mjl.clarivate.com/#opennewwindow 参考文献： https://www.zhihu.com/question/59562665 [2] http://muchong.com/html/201307/6077029.html [3] http://blog.sina.com.cn/s/blog_a05c4b760102yla8.html 文章来源: 如何检索CPCI-S

目录 绑定方法与非绑定方法 1.绑定方法 2.非绑定方法（staticmethod） isinstance和issubclass 内置函数 1.isinstance 2.issubclass 反射 反射定义 4个可以实现反省的函数（内置函数） 反射使用场景 绑定方法与非绑定方法 1.绑定方法 ​ 绑定方法:绑定给谁就应该由谁来调用,谁来调用就会将谁当做第一个参数传入 ​ ​ 绑定给对象的方法： ​ 类中定义的函数默认就是绑定给对象的 ​ 绑定给类的方法: ​ 为类中定义的函数加上一个装饰器classmethod 2.非绑定方法（staticmethod） 非绑定方法: 既不与类绑定,又不与对象绑定,意味着对象和类都可以来调用,无 论谁来调用都是一个普通的函数,没有自动传值的效果；为类中定义的函数加上一个装 饰器staticmethod。 示例 class Foo: def f1(self): print(self) @classmethod def f2(cls): print(cls) # <class '__main__.Foo'> @staticmethod def f3(x,y): print('f3',x+y) obj=Foo() print(Foo.f1) # 就是一个普通函数 <function Foo.f1 at 0x0000000002965620> print

GIS (geography) journal impact factor 参考链接：http://nlpgis.blogspot.nl/2013/10/gis-journal-impact-factor.html I was looking for impact factor information for GIS related journals and conferences. Finally, I came across a few resources and thereby summarize them here. gis.stackexchange.com has a general discussion on the top tier conferences in the field of GIS. Based on my limited personal experience, there isn't really a designated category such as top tier conference that GIS may possibly falls in. This is totally different from computer science or even geoscience. I guess, this might be why

F Greedy Sequence You're given a permutation a a of length n n ( 1 \le n \le 10^5 1 ≤ n ≤ 1 0 5). For each i \in [1,n] i ∈ [ 1 , n ], construct a sequence s_i s i ​ by the following rules: s_i[1]=i s i ​ [ 1 ] = i; The length of s_i s i ​ is n n, and for each j \in [2, n] j ∈ [ 2 , n ], s_i[j] \le s_i[j-1] s i ​ [ j ] ≤ s i ​ [ j − 1 ]; First, we must choose all the possible elements of s_i s i ​ from permutation a a. If the index of s_i[j] s i ​ [ j ] in permutation a a is pos[j] p o s [ j ], for each j \ge 2 j ≥ 2, |pos[j]-pos[j-1]|\le k ∣ p o s [ j ] − p o s [ j − 1 ] ∣ ≤ k ( 1 \le k \le 10
