We addressed the following criteria in developing the testbed in order to increase the likelihood that other computer science educators and researchers will adopt it as well, namely: the ability to program the robots in a high-level programming language; the ability of each robot to run programs using on-board processing capabilities; the ability of each robot to sense the environment in which it operates using on-board sensors; the ability of each robot to communicate with other robots in the testbed; and, the ability to incorporate additional robots in the testbed in a scalable manner. Given its programmability and communication capabilities, we chose Pololu's m3pi as the robot to use for constructing the testbed. We provide details of the various design choices and technical challenges we faced to build the testbed, including: programming m3pi robots in C/C++ to perform basic navigation operations, the graphical user interfaces we developed in Java and C# to track the robots, getting the robots to communicate using the Wixel and XBee wireless serial modules, and a virtual machine that we wrote in Python for the mbed microcontroller in order to give m3pi robots the communication capabilities needed for them to communicate using the XBee wireless serial module while navigating a grid. We conclude by outlining future promising directions to extend the testbed.","PeriodicalId":91384,"journal":{"name":"Proceedings of the 2014 ACM Southeast Regional Conference","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90826872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An ever-increasing complexity and the number of components present new challenges to software developers interested in finding operating points that strike an optimal balance between performance and energy consumed. In this paper we analyze the impact of thread scaling and frequency scaling on performance and energy in modern multicores. By exploiting recent additions to microprocessors that support energy estimation and power management, we measure execution times and energy consumed on an Intel Xeon 1240 v2 microprocessor when running the PARSEC benchmark suite. We conduct a number of experiments by varying the number of threads, 1 ≤ N ≤ 16, and processor clock frequency, 1.6 ≤ F ≤ 3.4 GHz. We find that the maximum performance is achieved when the number of threads matches or slightly exceeds the number of logical processors (8 ≤ N ≤ 12) and the clock frequency is at maximum (F = 3.4 GHz). The minimum energy is consumed when the processor clock frequency is in range 2.0 ≤ F ≤ 2.4 GHz. Finally, we find that the best performance at minimal energy is achieved when 8 ≤ N ≤ 12 and 2.8 ≤ F ≤ 3.1 GHz.","PeriodicalId":91384,"journal":{"name":"Proceedings of the 2014 ACM Southeast Regional Conference","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78652030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Popularity-based temporal relevance estimation for micro-blogging retrieval","authors":"Manar Alohaly, J. D. Teresco","doi":"10.1145/2638404.2675721","DOIUrl":"https://doi.org/10.1145/2638404.2675721","url":null,"abstract":"Finding relevant information among the vast amounts of data generated continuously by modern micro-blogging platforms has opened new challenges in information retrieval. Recent studies on time-based retrieval have shown that identifying the relevant time periods to be incorporated into the retrieval process is promising; by relevant time period we mean the peak time of a query that satisfies the temporal needs of the user's query. Or in other words, a time period at which the potential to find accurate matches for the query in a set of retrieved documents is relatively high when compared with other time periods. We refer to this as temporal relevance. In this paper, using data collected from Twitter, we propose a new temporal relevance estimation technique based on tracking documents published by the popular users, who have high indegree (i.e., number of followers). In this study we concentrate on queries that are short (one word) and popular, i.e., constantly consumed by micro-bloggers. We choose the simple frequency-based technique to estimate the relevant time period as a baseline against which we evaluate our technique. The results of our technique either match or suggest a better time period as the most relevant one, when compared with the baseline. In fact, for the type of queries in our study, narrowing our focus to the documents published by popular users produces a query-to-documents matching pattern that uncovers some information about temporal relevance that might otherwise be hidden. Also, our matching pattern reflects the nature of the real-world news events that are related to the user's query more so than the baseline, thus revealing the important time frames more clearly.","PeriodicalId":91384,"journal":{"name":"Proceedings of the 2014 ACM Southeast Regional Conference","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83289829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
