Competitive Power Down Methods In Green Computing, James Andro-Vasko
UNLV Theses, Dissertations, Professional Papers, and Capstones
For the power-down problem one considers a device which has states OFF, ON, and a number of intermediate states. The state of the device can be switched at any time. In the OFF state the device consumes zero energy and in the ON state it works at its full power consumption. The intermediate states consume only some fraction of energy proportional to the usage time but switching back to the ON state has has different constant setup cost depending on the current state. Requests for service (i.e. for when the device has to be in the ON state) are not …
Lock-Free Self-Adjusting Binary Search Tree, Sachiko Sueki
Lock-Free Self-Adjusting Binary Search Tree, Sachiko Sueki
UNLV Theses, Dissertations, Professional Papers, and Capstones
A binary search tree (BST) is a fundamental data structure for maintaining data in a way to allow fast search. As multi-core processors are widely used nowadays, such data structures require the ability to handle concurrent accesses to exploit the concurrent hardware. There are several algorithms on lock-based as well as lock-free BST with and without self-balancing. On the other hand, only a few reports can be found on lock-based self-adjusting BST. To the best of our knowledge, there are no algorithms for lock-free self-adjusting BST. Lock-free guarantees overall progress even if some processes fail, whereas lock-based algorithms fail to …

Degree Constrained Triangulation Of Annular Regions And Point Sites, Bhaikaji Gurung
Degree Constrained Triangulation Of Annular Regions And Point Sites, Bhaikaji Gurung
UNLV Theses, Dissertations, Professional Papers, and Capstones
Generating constrained triangulations of point sites distributed in the plane is a significant problem in computational geometry. We present theoretical and experimental investigation results for generating triangulations for polygons and point sites that address node degree constraints. We characterize point sites that have almost all vertices of odd degree. We present experimental results on the node degree distribution of Delaunay triangulations of point sites generated randomly. Additionally, we present a heuristic algorithm for triangulating a given normal annular region with an increment of even degree nodes.
Finding Top-K Dominance On Incomplete Big Data Using Map-Reduce Framework, Payam Ezatpoor
Finding Top-K Dominance On Incomplete Big Data Using Map-Reduce Framework, Payam Ezatpoor
UNLV Theses, Dissertations, Professional Papers, and Capstones
Incomplete data is one major kind of multi-dimensional dataset that has random-distributed missing nodes in its dimensions. It is very difficult to retrieve information from this type of dataset when it becomes huge. Finding top-k dominant values in this type of dataset is a challenging procedure. Some algorithms are present to enhance this process but are mostly efficient only when dealing with a small-size incomplete data. One of the algorithms that make the application of TKD query possible is the Bitmap Index Guided (BIG) algorithm. This algorithm strongly improves the performance for incomplete data, but it is not originally capable …

In E-COMMERCE websites such as Amazon.com, E-bay.com etc, consumers can submit their reviews along with a specific polarity rating (e.g. 1 to 5 stars at Amazon.com). There is a possibility of mismatch between review submitted and polarity of rating. For Amazon.com, a customer can submit a strongly positive review but …
High Utility Itemsets Identification In Big Data, Ashish Tamrakar
High Utility Itemsets Identification In Big Data, Ashish Tamrakar
UNLV Theses, Dissertations, Professional Papers, and Capstones
High utility itemset mining is an important data mining problem which considers profit factors besides quantity from the transactional database. It helps find the most valuable products/items that are difficult to track using only the frequent data mining set. An item that has a high-profit value might be rare in the transactional database despite its tremendous importance. While there are many existing algorithms which generate comparatively large candidate sets while finding high utility itemsets, the major focus is to reduce the computational time significantly with the introduction of pruning strategies. Another aspect of high utility itemset mining is to compute …

Non-Blocking Priority Queue Based On Skiplists With Relaxed Semantics, Ashok Adhikari
Non-Blocking Priority Queue Based On Skiplists With Relaxed Semantics, Ashok Adhikari
UNLV Theses, Dissertations, Professional Papers, and Capstones
Priority queues are data structures that store information in an orderly fashion. They are of tremendous importance because they are an integral part of many applications, like Dijkstra’s shortest path algorithm, MST algorithms, priority schedulers, and so on.
Since priority queues by nature have high contention on the delete_min operation, the design of an efficient priority queue should involve an intelligent choice of the data structure as well as relaxation bounds on the data structure. Lock-free data structures provide higher scalability as well as progress guarantee than a lock-based data structure. That is another factor to be considered in the …
