Basic function to locate and measure the positive peaks in a noisy data sets. Detects peaks by looking for downward zero-crossings in the smoothed third derivative that exceed SlopeThreshold and peak amplitudes that exceed AmpThreshold. Determines, position, height, and approximate width of each peak by least-squares curve-fitting the log of top part of the peak with a parabola.

Hadoop是一個用于運行應用程序在大型集群的廉價硬件設備上的框架。Hadoop為應用程序透明的提供了一組穩定/可靠的接口和數據運動。在 Hadoop中實現了Google的MapReduce算法,它能夠把應用程序分割成許多很小的工作單元,每個單元可以在任何集群節點上執行或重復執行。此外,Hadoop還提供一個分布式文件系統用來在各個計算節點上存儲數據,并提供了對數據讀寫的高吞吐率。由于應用了map/reduce和分布式文件系統使得Hadoop框架具有高容錯性,它會自動處理失敗節點。已經在具有600個節點的集群測試過Hadoop框架。

Learn how to: * Tokenize a null-terminated string * Create a search and replace function for strings * Implement subtraction for string objects * Use the vector, deque, and list sequence containers * Use the container adaptors stack, queue, and priority_queue * Use the map, multimap, set, and multiset associative containers * Reverse, rotate, and shuffle a sequence * Create a function object * Use binders, negators, and iterator adapters * Read and write files * Use stream iterators to handle file I/O * Use exceptions to handle I/O errors * Create custom inserters and extractors * Format date, time, and numeric data * Use facets and the localization library * Overload the [ ], ( ), and -> operators * Create an explicit constructor * And much, much more

Heapsort 1.A heap is a binary tree satisfying the followingconditions: -This tree is completely balanced. -If the height of this binary tree is h, then leaves can be at level h or level h-1. -All leaves at level h are as far to the left as possible. -The data associated with all descendants of a node are smaller than the datum associated with this node. Implementation 1.using a linear array not a binary tree. -The sons of A(h) are A(2h) and A(2h+1). 2.time complexity: O(n log n)

從ML-EM 重建算法入手,分析了貝葉斯模型的一些關鍵點,針對采用傳統方法求解MAP問題的局限性,提出一種用于正電子成像的貝葉斯神經網絡重建算法,為了保留邊緣信息,引入了二進制的保邊緣變量,并應用共軛神經網絡求解,模擬的重建結果表明,應用這種算法可以得到比ML-EM 算法更好的重建圖像@
