Fraglight: Shedding Light on Broken Pointcuts in Evolving Aspect-Oriented Software
N921 300 Jay St., Room N921, Brooklyn, NY, United StatesDespite providing many benefits, Aspect-Oriented Programming can experience complications as software evolves. Because the paradigm relies on queries over the program’s dynamic execution, certain program changes can adversely effect behavior. Deciding which queries have broken is a daunting venture, especially in large and complex systems. In this talk, Dr. Khatchadourian will present his ongoing, joint work on an automated approach that recommends likely modifications to aspects due to a certain code change. The approach has been implemented as an open-source extension to the popular Mylyn Eclipse Integrated Development Environment plugin, which maintains focused contexts of entities relevant to the task at hand.
More than Words: Advancing Prosodic Analysis
N906 300 Jay St., Room N906, Brooklyn, NY, United StatesUnderstanding prosody is critical to understanding speech communication. Spoken language processing (SLP) technology that approaches human levels of competence will necessarily include automatic analysis of prosody. Despite the importance of prosody in spoken communication, researchers are often unable to reliably incorporate prosodic information into applications. One explanation is a lack of compact, consistent, and universal representations of prosodic information. This talk will describe the state of the art in prosodic analysis and its use in spoken language processing with a focus on the development of new representations of prosody.
Big Data Challenges and Solutions
N906 300 Jay St., Room N906, Brooklyn, NY, United StatesSpeaker: Ashwin Satyanarayana Big data is set to offer tremendous insight. But with terabytes and petabytes of data pouring in to organizations today, traditional architectures and infrastructures are not up to the challenge. This begs the question: How do you … Continue reading
Minimum Energy Consumption for Rate Monotonic Algorithm in a Hard Real-Time Environment
N922A 300 Jay St., Room N922A, Brooklyn, NY, United StatesWe will discuss the problem of determination of the minimum energy consumption for rate monotonic algorithm in a hard real-time environment. The solution is obtained by Lagrange Multiplier method. Because of its iterative nature, a computer algorithm is developed.
Test Dependencies and the Future of Build Acceleration
N922A 300 Jay St., Room N922A, Brooklyn, NY, United StatesWith the proliferation of testing culture, many developers are facing new challenges. As projects are getting started, the focus may be on developing enough tests to maintain confidence that the code is correct. However, as developers write more and more tests, performance and repeatability become growing concerns for test suites. In our study of large open source software, we found that running tests took on average 41% of the total time needed to build each project - over 90% in those that took the longest to build. Unfortunately, typical techniques for accelerating test suites from literature (like running only a subset of tests, or running them in parallel) can’t be applied in practice safely, since tests may depend on each other. These dependencies are very hard to find and detect, posing a serious challenge to test and build acceleration. In this talk, I will present my recent research in automatically detecting and isolating these dependencies, enabling for significant, safe and sound build acceleration of up to 16x.
Static Analysis and Verification of C Programs
N922A 300 Jay St., Room N922A, Brooklyn, NY, United StatesStatic Analysis and Verification of C Programs by Subash Shankar, Hunter College, City University of New York. Recent years have seen the emergence of several static analysis techniques for reasoning about programs. This talk presents several major classes of techniques and tools that implement these techniques. Part of the presentation will be a demonstration of the tools.
How We Use Functional Programming to Find the Bad Guys
N922A 300 Jay St., Room N922A, Brooklyn, NY, United StatesIn this talk, Richard Minerich will discuss the research activities of Bayard Rock and its approaches to build tools to find the “bad guys”.
Pharmacology Powered by Computational Analysis: Predicting Cardiotoxicity of Chemotherapeutics
N922A 300 Jay St., Room N922A, Brooklyn, NY, United StatesCardiotoxicity is unfortunately a common side effect of many modern chemotherapeutic agents. The mechanisms that underlie these detrimental effects on heart muscle, however, remain unclear. The Drug Toxicity Signature Generation Center at ISMMS aims to address this unresolved issue by providing a bridge between molecular changes in cells and the prediction of pathophysiological effects. I will discuss ongoing work in which we use next-generation sequencing to quantify changes in gene expression that occur in cardiac myocytes after they are treated with potentially toxic chemotherapeutic agents. I will focus in particular on the computational pipeline we are developing that integrates sophisticated sequence alignment, statistical and network analysis, and dynamical mathematical models to develop novel predictions about the mechanisms underlying drug-induced cardiotoxicity.
