[+] Keywords | [+] Abstract | Journal info | TOP (#1) Journal, "Science - NUCLEAR SCIENCE & TECHNOLOGY" Section Battery; Large-scale battery pack; Reconfigurable battery management system; State of health; Wear leveling As the market and the application areas of high capacity battery energy storage systems are rapidly increasing, there is a correspondingly high interest in the topic of minimizing battery state of health degradation in battery packs. In this article, a novel method for battery management in large-scale battery packs is introduced, aiming to minimize battery degradation by enforcing a special wear leveling (WL) policy, adapted from the flash memory arrays. Using this method in conjunction with a hybrid mathematical-electrochemical battery model, a reconfigurable battery management system (BMS) is proposed and evaluated. The results of the performance analysis and in-depth comparisons with other state-of-the-art solution shows that the proposed method achieves significantly longer operating times for the battery packs-for example, 415% improvement over the classical BMS in the load current variation scenario. As the computing and memory requirements are relatively low, the new battery WL method can also be implemented on embedded systems with limited resources. |

Deep learning techniques based on recurrent neural networks with memory, such as the long short-term memory {LSTM) and gated recurrent unit {GRU), have very promising advantages, when compared to other SOH estimation algorithms. This work addresses the battery SOH prediction based on GRU. A complete BMS is presented along with the internal structure and configuration parameters. The neural network was highly optimized by adaptive moment estimation {Adam) algorithm. Experimental data show very good estimation results for different temperature values, not only at room value. Comparisons performed against other relevant estimation methods highlight the performance of the recursive neural network algorithms such as GRU and LSTM, with the exception ofthe battery regeneration points. Compared to LSTM, the GRU algorithm gives slightly higher estimation errors, but within similar prediction error range, while needing significantly fewer parameters {about 25% fewer), thus making it a very suitable candidate for embedded implementations. |

[+] Keywords | [+] Abstract | Journal info | Full paper | UEFISCDI PRECISI Prize Cyber physical systems; Real-time scheduling; Mixed criticality systems; Multiple processing units Cyber physical systems (CPSs) are a fast-evolving technology based on a strong synergy between heterogeneous sensing, networking, computation and control modules. When coping with critical applications that require real-time performance and autonomous operation in uncertain conditions, the design of such complex systems is still facing significant difficulties. A particular challenge in this respect derives from the software intensive nature of these systems - the need to develop flexible and specifically tailored task scheduling techniques. In our view, an appropriate line of thinking is to take advantage of mixed criticality concepts following the lessons learned from avionics and automotive domains, where complexity, safety, determinism and real-time constraints are extreme. From this perspective, our work aims at facilitating the integration of mixed criticality systems-based strategy in cyber physical systems by identifying the particularities of the latter and their influence on scheduling mechanisms, by describing the standard mixed-criticality task model in the cyber physical systems context, and by analyzing and proposing the most suitable scheduling algorithms to be implemented in cyber physical systems. Moreover, the perspectives on future developments in this area are discussed, as new horizons in research arise with the integration of mixed criticality concepts in the cyber physical systems context. |

[+] Keywords | [+] Abstract | Journal info | Wiley Journal Index Record | TOP (#1) Journal, "Science - NUCLEAR SCIENCE & TECHNOLOGY" Section | UEFISCDI PRECISI Prize Battery state estimation; State of health; Remaining useful life; Battery model; Embedded application; Battery fuel gauge Estimating the dynamic status parameters of a battery, such as its state of health (SoH) and remaining useful life (RUL), is still a very difficult and complex task. In this paper we perform a structured review of the most relevant state of the art models, algorithms and commercial devices employed in the estimation of the SoH/RUL battery performance figures, in the context of embedded applications. The models and estimation techniques are thoroughly classified and, for each taxonomy class, a presentation of the working principles is made. A comprehensive set of metrics is then introduced for the evaluation of the SoH/RUL estimation techniques from the perspective of their implementation and operation efficiency in embedded systems. These algorithms are then analyzed and discussed in a comparative manner, with concrete figures and results. The capability and the performance of the different types of off-the-shelf fuel gauges to estimate the battery SoH/RUL parameters are also evaluated in this paper. |

[+] Keywords | [+] Abstract | Cover picture | Journal info Foreground extraction; Videoconference; Optical flow; Graph cut; Motion segmentation; Real-time video processing Immersive videoconferences have added a new dimension to remote collaboration by bringing participants together in a common virtual space. To achieve this, the conferencing system must extract in real-time the foreground from each incoming video stream and translate it into the shared virtual space. The method presented in this paper differentiates itself in the sense that no prior training or assumptions on the video content are used during foreground extraction. A temporally coherent mask is created based on motion cues obtained from the video stream and is used to provide a set of hard constraints. Based on these constraints, a graph cut algorithm is employed to produce the pixel-accurate foreground segmentation. The obtained results are evaluated using a state-of-the-art perceptual metric to provide an objective assessment of the method accuracy and reliability. Furthermore, the presented approach makes use of parallel execution in order to achieve real-time processing capabilities. |

[+] Keywords | [+] Abstract | Cover picture | Journal info | IEEE Index Record (Inspec) Battery management; Battery-powered device; Nickel-metal hydride (Ni-MH); State-of-health (SoH) prediction Battery-powered embedded systems have known a rapid evolution in recent years, as nickel-metal hydride (Ni-MH) battery technology has enabled important reductions in size and proportional increases in total capacity over the older nickel-cadmium (Ni-Cd) and lead-acid battery types. This paper addresses the problem of state-of-health (SoH) estimation and prediction for use in resource-constrained Ni-MH-battery-powered embedded systems. We propose a novel SoH prediction methodology, presenting both a theoretical analysis of the estimation algorithm and the detailed description of hardware and software implementation. Two versions of estimation algorithms are proposed, along with the analysis of their performances in terms of prediction accuracy and required processing power, as the SoH prediction is designed to run online, being part of an embedded battery management system. |

[+] Keywords | [+] Abstract | Cover picture | Journal info Genetic algorithms; Job-shop scheduling; Initial populations; Chromosomes This paper presents an efficient method of enhancing genetic algorithms (GAs) for solving the Job-Shop Scheduling Problem (JSSP), by generating near optimal initial populations. Since the choice of the initial population has a high impact on the speed of the evolution and the quality of the final results, we focused on generating its individuals using genetically evolved priority dispatching rules. Our experiments show a significant increase in quality and speed of scheduling with GAs, and in some cases the evolved priority rules alone determined better solutions then the GA itself. The analyzed reference GA uses Giffler & Thompson (GT) heuristic and priority lists. To speed up the generation of priority rules, we have used a weighted sum of priority rules formula that revealed significantly better performances than Genetic Programming (GP). For evaluation of the proposed algorithm, the well known benchmark data sets from Fisher & Thompson (F&T) and Laurence Kramer (LA) have been used. |

[+] Keywords | [+] Abstract | Journal Table of Contents | ACM Index Record Power consumption; Multi-threading; Multi-core; Mobile applications; Power profiling One constant in computing which is true also for mobile computing is the continue requirement for greater performance. Every performance advance in mobile processors leads to another level of greater performance demands from newest mobile applications. However, on battery powered devices performance is strictly limited by the battery capacity, therefore energy efficient applications and systems have to be developed. The power consumption problem of mobile systems is in general a very complex one and remained very actual for quite a long time. In this paper we aim to define a software execution framework for mobile systems in order to characterize the power consumption profile of multi-threading mobile applications. Study results for different thread libraries, multi-core processors and multithreaded parallelized applications are also presented. |

[+] Keywords | [+] Abstract | Cover picture | Conference guide | Preprint version Real-time systems; Computational intelligence; Informatics; Scheduling algorithms; Task analysis This paper addresses the problem of real-time scheduling on multiprocessor systems for periodic tasks when scheduling jitter is not allowed. A partitioned real-time scheduling method based on a table-driven uniprocessor algorithm called fixed execution non-preemptive (FENP) is proposed as a solution for this problem. An analysis of the new proposed algorithm is provided in terms of scheduling jitter and schedulability ratio, by comparison against other popular partitioned real-time scheduling algorithms. |

Lesser edge displacement means more accurate results, and this is the aim of most edge detectors. We present a novel algorithm for obtaining highly localized edges from grayscale images, based on an analogy between phase congruency maps and digital elevation models. In the first step, phase congruency is used to obtain an initial edge map, which is then processed in a second step by a modified ridge-detection algorithm in order to obtain an increased edge localization. |

[+] Keywords | [+] Abstract Human spine geometry; Scoliosis The majority of the population suffers of mild or severe spinal column deformations, such as scoliosis, lordosis, cifosis, leading to the reduction of the personal comfort and the reduction of the physical and intellectual effort capacity, also leading to severe distortions of thorax shape and alteration of the respiratory process. In order to emit the right diagnosis it is necessary to measure 3D geometry parameters of the human spine including the rotations angle between the vertebrae. The classical non-invasive investigations methods don't establish vertebrae rotation angle. This paper presents a method for the determination of the vertebrae rotation angle with a noninvasive investigations method using the ultrasound device. It is assumed that every vertebra is associated with a precision point and a characteristic line. |

[+] Keywords | [+] Abstract | Cover picture | Conference guide | IEEE Index Record (Inspec) Serial communications; Monitoring; Embeeded systems; Microcontrollers More and more microcontrollers are embedded in a large area of products from industrial to domestic domains. A good example is the automobile, a modern one containing tens of microcontrollers. As their number increased the communication between them became necessary. The serial solution was preferred and a lot of serial buses and protocols were developed optimizing different parameters of the communication. Several examples are: RS232, LIN, SPI, CAN and so on. Monitoring serial communications is necessary in R&D phase, e.g. for creating virtual transfer partners, and in testing and debugging phases. The paper describes a message based monitoring tool for the RS232 bus and monitoring tools for the LIN and SPI buses. Many microcontrollers contain the LIN and SPI buses and almost all of them include the RS232 bus. The created tools work in passive mode, monitoring the transfers and sending the data to a PC or in active mode (only for the LIN bus), interfering in the communication and sending headers, responses or injecting typical errors. |

[+] Keywords | [+] Abstract | Cover picture | Proceedings info Collective robotic environments; Emergence; Robotic behavior In a ubiquitous environment, intellignet functions are embedded in objects around the user, thus enabling him to create variuos functionalities by combining those objects. The collaborative robotic environments are a new approach to the coordination of multirobot systems which usually consist of numerous, relatively simple, small sized robots. The CORE-TX system (COllaborative Robotic Environment - the Timisoara eXperiment) is conceived as a complex platform composed by a heterogeneous set of autonomous microsystems with embedded intelligence, a collaborative communication environment and a central entity with supervising functions. This paper describes the general architecture of the CORE-TX system, the system model; this paper also contains a brief comparison bBetween CORE-TX and state-of-the-art collaborative environments. |

We describe the specific communication protocol specifications along with the characteristic details of their implementation on the DSP-based system. We also emphasize the routines created for testing the implemented communication protocols and the interpretation of their results. Finally, we make some comparative study and performance analysis on the implemented communication protocols. |
