Complex, cyber-physical systems must be founded on a digital blueprint that provides the most accurate representation of the system by federating information from engineering models across multiple enterprise repositories. This blueprint would serve as the digital surrogate of the system and evolve as the actual system matures across its lifecycle, from conception and design to production and operations. This paper presents a graph-based approach for realizing the digital blueprint, which we refer to as the Total System Model. The paper is divided into five parts. Part 1 provides an introduction to use cases for model-based systems engineering. Part 2 introduces graph concepts for the Total System Model. Part 3 provides a demonstration of the graph-based approach using Syndeia software as a representative application. Part 4 provides a summary of this paper, and Part 5 lays out potential directions for future work. Copyright © 2017 by Intercax LLC. Published and used by INCOSE with permission.

Flight deck-based vision system technologies, such as Synthetic Vision (SV) and Enhanced Flight Vision Systems (EFVS), may serve as a revolutionary crew/vehicle interface enabling technologies to meet the challenges of the Next Generation Air Transportation System Equivalent Visual operations (EVO) concept – that is, the ability to achieve the safety of current-day Visual Flight Rules (VFR) operations and maintain the operational tempos of VFR irrespective of the weather and visibility conditions. One significant challenge lies in the definition of required equipage on the aircraft and on the airport to enable the EVO concept objective. A motion-base simulator experiment was conducted to evaluate the operational feasibility, pilot workload and pilot acceptability of conducting straight-in instrument approaches with published vertical guidance to landing, touchdown, and rollout to a safe taxi speed in visibility as low as 300 ft runway visual range by use of onboard vision system technologies on a Head-Up Display (HUD) without need or reliance on natural vision. Twelve crews evaluated two methods of combining dual sensor (millimeter wave radar and forward looking infrared) EFVS imagery on pilot-flying and pilot-monitoring HUDs as they made approaches to runways with and without touchdown zone and centerline lights. In addition, the impact of adding SV to the dual sensor EFVS imagery on crew flight performance, workload, and situation awareness during extremely low visibility approach and landing operations was assessed. Results indicate that all EFVS concepts flown resulted in excellent approach path tracking and touchdown performance without any workload penalty. Adding SV imagery to EFVS concepts provided situation awareness improvements but no discernible improvements in flight path maintenance. © 2016, American Institute for Aeronautics and Astronautics.

Physics engine is an important auxiliary middleware component library needed by the graphics display system. It is used to provide realistic animation effects in applications ranging from games, multimedia, user interfaces etc based on Newtonian laws of physics. With the evolution of high-end graphics on embedded platforms, there is a subtle need for the provision of a dedicated physics library whose processing can be offloaded to separate processing unit other than the main processor to maintain the optimal frame-rate requirement of the end user application. Currently physics processing is accelerated using high power high performance architectures like graphics processing units (GPU) or physics processing units (PPU). Reconfigurable computing facilitates execution of software with higher flexibility than that of any dedicated hardware while providing increased performance and low power consumption. In this paper we demonstrate that physics processing can be optimized using a reconfigurable processor. We also propose a novel method of executing collision solver algorithm in a physics engine library on Coarse Grained Reconfigurable Array (CGRA) based reconfigurable processors.

Personalized genomic medicine aims to revolutionize healthcare by applying our growing understanding of the molecular basis of disease for effective diagnosis and personalized therapy. Computational research in this arena has major challenges such as handling large volume of highly heterogeneous data sets. To extract knowledge, researchers must integrate data from several sources and efficiently query these large and diverse data sets. This presents daunting informatics challenges such as suitable data representation for computational inference (knowledge representation), linking heterogeneous data sets (data integration) and keeping track of the source of the data to be aggregated. Many of these challenges can be categorized as data integration problems. In this paper, we present relevant methodologies from the field of data integration as potential solution for such challenges encountered by computational biologist while handling diversified data. The work presented in the paper represents the first crucial step towards identifying cancer biomarkers leading to cancer pathways signatures and personalized medicine.

IEEE International Conference on Bioinformatics and Biomedicine Workshops (BIBMW)

作者： B. S. Raghavendra Ajit S. Bopardikar Samsung India Software Operations Samsung Advanced Institute of Technology India Bangalore India

In this paper, we propose a supervised classification approach based on Euclidean distance for identifying CpG islands in DNA sequences. We first extract features from the training data set which is extracted from annotated DNA sequences. CpG island locations in a test data sequence are identified by calculating Euclidean distance in the feature space. A moving window method has been used to screen the input test sequence. The performance of the proposed method is verified experimentally on EMBL human DNA database. Proposed approach gives superior performance results over most of the available CpG island detectors and has potential application in annotating CpG islands in large human sequences.

International Conference on Internet Multimedia Services Architecture and Applications, IMSAA

In this paper, we present “SESGARH”, a scalable and extensible smart-phone based healthcare system, to provide realtime continuous monitoring of health conditions of individuals seeking professional healthcare. The proposed system suggests an “anytime anywhere” health monitoring mechanism via an application providing rich contextual visualization of health data through easy-to-use interfaces. Using SESGARH, patients with chronic illnesses can send disease symptoms and other critical health information to a physician, who can analyze this data remotely and prescribe e-prescriptions. SESGARH can significantly minimize time taken for transmission of healthcare data from patient to physician and vice-versa, and improve the reach and quality of healthcare services. Proposed system is based on the ISO/IEEE11073 (X73) family of standards supporting high quality medical sensors, as well as wireless transport (e.g. Bluetooth, WiFi, Zigbee) for access to faster and reliable communication network resources. JSON, a lightweight text-based open standard, is used to represent the data, which is interchanged between SESGARH and remote server over HTTP. We have successfully implemented and demonstrated SESGARH - using ECG body sensors, a Smart-phone device acting as a mobile gateway running the application, and a remote server to which the physician is connected.

Parallelization of face detection engine

Parallelization of face detection engine

Video processing is computationally intensive and often has accompanying real-time or super-real-time requirements. For example, video tagging and surveillance systems need to robustly analyze video and automatically recognize the faces in real time. The semiconductor industry has shifted from increasing clock speeds to a strategy of growth through increasing core counts. This shift from single core to multi-core presents a major challenge to application developers to exploit sufficient parallelism in performance-sensitive applications. This give rise to a new computation paradigm for developing more advance algorithms. In this paper, we present a method to efficiently parallelize face detection which can be extended to any object detection algorithms for SMP architectures. We also show that a well-designed parallel code of face detection algorithm will result in a performance gain in excess of 2X on dual core systems. © 2010 IEEE.
