Software search is not a science, even among scientists: A survey of how scientists and engineers find software
Journal of Systems and Software, 2018Co-Authors: Michael Hucka, Matthew J. GrahamAbstract:Improved software discovery is a prerequisite for greater software reuse: after all, if someone cannot find software for a particular task, they cannot reuse it. Understanding people’s approaches and preferences when they look for software could help improve facilities for software discovery. We surveyed people working in several scientific and engineering fields to better understand their approaches and selection criteria. We found that even among highly-trained people, the rudimentary approaches of relying on general Web searches, the opinions of colleagues, and the literature were still the most commonly used. However, those who were involved in software development differed from nondevelopers in their use of social help sites, software project repositories, software catalogs, and organization-specific mailing lists or forums. For example, software developers in our sample were more likely to search in community sites such as Stack Overflow even when seeking Ready-to-Run software rather than source code, and likewise, asking colleagues was significantly more important when looking for Ready-to-Run software. Our survey also provides insight into the criteria that matter most to people when they are searching for Ready-to-Run software. Finally, our survey also identifies some factors that can prevent people from finding software.

Software search is not a science, even among scientists
arXiv: Computers and Society, 2016Co-Authors: Michael Hucka, Matthew J. GrahamAbstract:When they seek software for a task, how do people go about finding it? Past research found that searching the Web, asking colleagues, and reading papers have been the predominant approaches---but is it still true today, given the popularity of Facebook, Stack Overflow, GitHub, and similar sites? In addition, when users do look for software, what criteria do they use? And finally, if resources such as improved software catalogs were to be developed, what kind of information would people want in them? These questions motivated our cross-sectional survey of scientists and engineers. We sought to understand the practices and experiences of people looking for Ready-to-Run software as well as people looking for source code. The results show that even in our highly educated sample of people, the relatively unsophisticated approaches of relying on general Web searches, the opinions of colleagues, and the literature remain the most popular approaches overall. However, software developers are more likely than non-developers to search in community sites such as Stack Overflow and GitHub, even when seeking Ready-to-Run software rather than source code. We also found that when searching for source code, poor documentation was the most common reason for being unable to reuse the code found. Our results also reveal a variety of characteristics that matter to people searching for software, and thus can inform the development of future resources to help people find software more effectively.

MIMO-OFDM Wireless Communications with MATLAB® - Introduction to OFDM
MIMO-OFDM Wireless Communications with MATLAB®, 2010Co-Authors: Yong Soo Cho, Jaekwon Kim, Won Young Yang, Chung G. KangAbstract:This chapter presents the basic principle of OFDM (orthogonal frequency division multiplexing) transmission techniques and their performance, including the Ready-to-Run MATLAB? programs for the simulation. It also introduces the concept of orthogonal frequency division multiple access (OFDMA), which is the multiple access technique associated with OFDM.

MIMO-OFDM Wireless Communications with MATLAB® - Signal Detection for Spatially Multiplexed MIMO Systems
MIMO-OFDM Wireless Communications with MATLAB®, 2010Co-Authors: Yong Soo Cho, Jaekwon Kim, Won Young Yang, Chung G. KangAbstract:This chapter presents both soft-decision and hard-decision signal detection techniques for spatially-multiplexed single-user MIMO systems, in which the multiple independent parallel data streams are supported by the multiple transmit and receive antennas. It also includes the Ready-to-Run MATLAB? programs for the simulation.
-
MIMO-OFDM Wireless Communications with MATLAB® - Synchronization for OFDM
MIMO-OFDM Wireless Communications with MATLAB®, 2010Co-Authors: Yong Soo Cho, Jaekwon Kim, Won Young Yang, Chung G. KangAbstract:This chapter first analyzes the effects of symbol timing offset (Sto) and carrier frequency offset (CFO) in OFDM systems and then, discusses the synchronization techniques that estimate these offsets either in a time domain or a frequency domain. It also presents the Ready-to-Run MATLAB? programs for the simulation of those techniques.

MIMO-OFDM Wireless Communications with MATLAB® - Exploiting Channel State Information at the Transmitter Side
MIMO-OFDM Wireless Communications with MATLAB®, 2010Co-Authors: Yong Soo Cho, Jaekwon Kim, Won Young Yang, Chung G. KangAbstract:This chapter presents the transmission techniques, such as the pre-coding techniques and antenna selection techniques, that exploit the channel state information (CSI) available on the transmitter side, allowing for an increase in the channel capacity and improvement on error performance. It also presents the Ready-to-Run MATLAB? programs for the simulation of those techniques.

Ready to Run the wards a descriptive follow up study assessing future doctors clinical skills
BMC Medical Education, 2018Co-Authors: Till Johannes Bugaj, Christoph Nikendei, Jan B Groener, Jan Stiepak, Julia Huber, Andreas Moltner, Wolfgang Herzog, Ansgar KoechelAbstract:Recent studies have shown that clinical tasks only represent a small percentage in the scope of final-year medical students’ activities and often lack sufficient supervision. It appears that final-year medical students are frequently deployed to perform “routine tasks” and show deficits in the performance of more complex activities. This study aimed to evaluate final-year students’ clinical performance in multiple impromptu clinical scenarios using video-based assessment. We assessed final-year medical students’ clinical performance in a prospective, descriptive, clinical follow-up study with 24 final-year medical students during their Internal Medicine rotation. Participating students were videotaped while practicing history taking, physical examination, IV cannulation, and case presentation at the beginning and end of their rotation. Clinical performance was rated by two independent, blinded video assessors using binary checklists, activity specific rating scales and a five-point global rating scale for clinical competence. Students’ performance, assessed by the global rating scale for clinical competence, improved significantly during their rotation. However, their task performance was not rated as sufficient for independent practice in most cases. Analysis of average scores revealed that overall performance levels differed significantly, whereby average performance was better for less complex and more frequently performed activities. We were able to show that students’ performance levels differ significantly depending on the frequency and complexity of activities. Hence, to ensure adequate job preparedness for clinical practice, students need sufficiently supervised and comprehensive on-ward medical training.
