This popularity is largely due to their low complexity and for presenting similar performances when compared to non binary descriptors, like SIFT. In literature, many researchers have applied binary descriptors in conjunction with mid-level representations (e.g., Bag-of-Words). However, despite these works have demonstrated promising results, their main problems are due to use of a simple mid-level representation and the use of binary descriptors in which rotation and scale invariance are missing. In order to address those problems, we propose to evaluate state-of-the-art binary descriptors, namely BRIEF, ORB, BRISK and FREAK, in a recent mid-level representation, namely BossaNova, which enriches the Bag-of-Words model, while preserving the binary descriptor information. Our experiments carried out in the challenging PASCAL VOC 2007 dataset revealed outstanding performances. Also, our approach shows good results in the challenging real-world application of pornography detection.","PeriodicalId":285655,"journal":{"name":"Proceedings of the 29th Annual ACM Symposium on Applied Computing","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116928311","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}

Three of the studied organizations have active and structured process modeling programs but underuse the models. We contend that the proposed framework can form a basis for a value-aware process modeling governance framework.","PeriodicalId":285655,"journal":{"name":"Proceedings of the 29th Annual ACM Symposium on Applied Computing","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124924234","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}

Similarly, model transformations are also software assets and can be reused with the same techniques. However, their applicability in the model transformations domain demands an extra effort to test the generated/adapted assets. Automated test cases should consider isolated transformations and also their combined use in a model transformation chain, that can vary according to different needs in software projects, e.g. libraries and frameworks. In order to facilitate the specification of automated test cases, this paper presents a JUnit extension to support unit and integration tests that execute dynamic SPL-based model transformation chains.","PeriodicalId":285655,"journal":{"name":"Proceedings of the 29th Annual ACM Symposium on Applied Computing","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124982935","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}

However, how to adapt current Web technologies to this booming trend still remains elusive. In this paper, a novel approach to support stereoscopic 3D Web is proposed that is to extend existing HTML, CSS and JavaScript languages. Under our stereoscopic 3D web model, each element in a web page can be assigned with a depth value, which is essential for the perception of 3D depth. WebKit is modified to accomplish a stereoscopic 3D web browser, and as the result turned out, each element of a web page can be seen in a truly 3D space on a stereoscopic 3D device that appears to be floating from the display surface. It is shown that this approach provided a new ground-breaking innovation for user experience.","PeriodicalId":285655,"journal":{"name":"Proceedings of the 29th Annual ACM Symposium on Applied Computing","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125317870","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}

By exploiting access locality, most parts of a mapping table of a flash translation layer (FTL) keep unchanged since wear leveling is adopted only when a block tends to be unreliable. Because the mapping table is changed rarely, we can reduce the mounting time by record most portion of the mapping table on the flash drive. Furthermore, we can give short codes to the data blocks that erased frequently (because the locality) when recording the erase counts in a log structure. We observe that the algorithm can extend the lifetime of a flash drive and reduce mounting time in most situations.","PeriodicalId":285655,"journal":{"name":"Proceedings of the 29th Annual ACM Symposium on Applied Computing","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115039570","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}

This work presents DuoGrapher, a text entry method, and SwingingFoot, an interaction technique, which aim to improve their communication skills by leveraging these motor capabilities. The idea is to attach in one of the user's feet an accelerometer-equipped device, which detect and transmit the movements to a second device located in front of the users' eyes. DuoGrapher interpreted the movements as characters according to the codification being used. Our design is informed by the motor capabilities of a male, in his 60s, with a motor neuron disease. We developed a prototype and tested it with 15 able-bodied users in order to test the usability of the system before doing further studies with motor-impaired individuals. Our goal is understand the challenges of a foot-based system interaction. It became evident that a semi-automatic calibration mechanism and a simpler mapping from movements to character are needed in order to reduce errors.","PeriodicalId":285655,"journal":{"name":"Proceedings of the 29th Annual ACM Symposium on Applied Computing","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115177351","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}

The presence of various different, bespoke and incompatible, methods of instrumentation to obtain energy readings is currently limiting the widespread use of energy data in software development. This paper presents EACOF, a modular Energy-Aware Computing Framework that provides a layer of abstraction between sources of energy data and the applications that exploit them. EACOF replaces platform specific instrumentation through two APIs---one accepts input to the framework while the other provides access to application software. This allows developers to profile their code for energy consumption in an easy and portable manner using simple API calls. We outline the design of our framework and provide details of the API functionality. In a use case, where we investigate the impact of data bit width on the energy consumption of various sorting algorithms, we demonstrate that the data obtained using EACOF provides interesting, sometimes counter-intuitive, insights.
