[Industry research] A Survey of Spectrum Sensing Algorithms DL : 0: A Survey of Spectrum Sensing Algorithms The spectrum sensing problem has gained new aspects with cognitive radio and opportunistic spectrum access concepts. It is one of the most challenging issues in cognitive radio systems. In this paper, a survey of spectrum sensing methodologies for cognitive radio is presented. Various aspects of spectrum sensing problem are studied from a cognitive radio perspective and multi-dimensional spectrum sensing concept is introduced. Challenges associated with spectrum sensing are given and enabling spectrum sensing methods are reviewed. The paper explains the cooperative sensing concept and its various forms. External sensing algorithms and other alternative sensing methods are discussed. Furthermore, statistical modeling of network traffic and utilization of these models for prediction of primary user behavior is studied. Finally, sensing features of some current wireless standards are given.

[Industry research] SOCR_CD DL : 0: This book was written to provide modern pedagogical perspective into technology- enhanced blended learning and instruction. It reflects the direction of amalgamation of knowledge from multiple disciplines with recent open networking and technological advances. This trend is anticipated to accelerate in the next decade with seamless integration of open-access data, learning materials, computational resources and collaborative environments connected via language, platform and geo-politically agnostic interfaces. There are four novel features of this book – it is community- built, completely free-open-access (in terms of use and contributions), blends concepts with technology and it is electronically available online in multilingual format. This book covers the narrow scientific area of probability and statistics education however, the principles we promote in the book can easily be extended to all other science and technology fields. -This book was written to provide modern pedagogical perspective into technology- enhanced blended learning and instruction.

[Industry research] Extraction-of-Health-Parameters-using-Photoplethy DL : 0: Health parameters like heart rate (HR) and heart rate variability (HRV) have been captured using conventional methods which give good signals. Also, there have been recent advances in photoplethysmographic imaging which has made it possible to capture these parameters in a non-invasive, low-cost and comfortable way. All of these new techniques have been implemented in languages other than C. C language is well known for serving portability on systems of different architectures. In this paper, we will discuss these techniques from the perspective of implementation in C for the extraction of health information and will suggest improvements that can be applied to it.
