Motivated by the numerous healthcare applications of molecular communication within Internet of Bio-Nano Things (IoBNT) paradigm, this paper addresses the problem of abnormality detection in a blood vessel using multiple biological embedded computing devices called cooperative biological nanomachines (CNs), and a common receiver called the fusion center (FC). Due to blood flow inside a vessel, each CN and the FC are assumed to be mobile. In this paper, each CN performs abnormality detection with certain probabilities of detection and false alarm. The CNs report their local decisions to an FC over a diffusion-advection blood flow channel using different types of molecules in the presence of inter-symbol interference, multi-source interference, and counting errors. The FC employs the OR and AND logic-based fusion rules to make the final decision after decoding the local decisions using the sub-optimal detectors based on the approximation of the log-likelihood ratio. For the aforementioned system, probabilities of detection, and false alarm at the FC are derived. Finally, simulation results are presented to validate the derived analytical results, which provide important insights. © 2015 IEEE.

The work reported in this article addresses the challenge of building models for non-trivial aerobatic aircraft maneuvers in an automated fashion. It is built using a Behavioural Cloning approach where human pilots provide a set of example maneuvers used by a Machine Learning algorithm to induce a control model for each maneuver. The best examples for each maneuver were selected using a set of objective evaluation metrics. Using those example sets, robust models were induced that could replicate (and in some cases outperform) the human pilots that provided the examples (the clean-up effect). Complete complex maneuvers were performed using a meta-controller capable of sequencing the basic ones learned by imitation. This endeavor was rewarded by the results that show several Machine Learning models capable of performing highly complex aircraft maneuvers. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

This paper presents algorithms for improving the performance of parallel programs on multiprogrammed shared-memory NUMA multiprocessors, via the use of user-level dynamic page migration. The idea that drives the algorithms is that a page migration engine can perform accurate and timely page migrations in a multiprogrammed system if it can correlate page reference information with scheduling information obtained from the operating system. The necessary page migrations can be performed as a response to scheduling events that break the implicit association between threads and their memory affinity sets. We present two algorithms that use feedback from the kernel scheduler to aggressively migrate pages upon thread migrations. The first algorithm exploits the iterative nature of parallel programs, while the second targets generic codes without making assumptions on their structure. Performance evaluation on an SGI Origin2000 shows that our page migration algorithms provide substantial improvements in throughput of up to 264% compared to the native IRIX 6.5.5 page placement and migration schemes.

As information develops, many individuals or communities change their habits in obtaining information, which is usually consumed in large quantities, so that sometimes it is difficult to understand, it becomes easier to get information in summary form, so this research applies the text summarization technique to Indonesian language documents using the Flax T5 model. is the development of transformer-based google. The results of this study are the use of parameters from the Flax T5 model that can affect the performance of text summaries, evidenced by the number of epochs 20, batch size 64 producing ROUGE-1 of 0.24. the ROUGE-2 value is 0.3 and the ROUGE-L value is 0.31, while the epoch value is 60, batch size 128 makes ROUGE-1 0.35, ROUGE-2 value is 0.38 and the ROUGE-L value is 0.36. while the epoch value of 100 and the batch size value of 256 produce a ROUGE-1 value of 0.5, a ROUGE-2 value of 0.54, and a ROUGE-L value of 0.55. However, this model has limitations in text lengths of more than 150 because it will make the training time so long that it is highly recommended not to use text lengths that exceed 150 words. © 2023 IEEE.

This paper presents a soft-switched AC/DC power converter structure, useful for current-fed inverters and forced commutated PWM rectifiers with an inductive load. Typical applications are high-power AC motor drives, magnet power supplies and active power filters with inductive energy storage. As compared to hard switched converters, the proposed solution calls for some increase of the circuit complexity, but provides improved input and output performances due to the higher switching frequency. Further improvements are ensured by proper control of the commutation process. Actual power converter capabilities are demonstrated by experimental results. © 1993 IEEE.

Due to the increasing prevalence of multicore microprocessors and accelerator technologies in modern supercomputer design, new techniques for designing scientific applications are needed, in order to efficiently leverage all of the power inherent in these systems. The dataflow programming paradigm is well-suited to application design for distributed and heterogeneous systems than other techniques. Traditionally in dataflow middleware, application data domains are statically partitioned and distributed among the processors using a demand-driven algorithm. Unfortunately, this task scheduling technique can cause severe load imbalances in heterogeneous environments. Furthermore, in the presence of different types of processors, the optimum datasize can be different for each processor type. To solve the load imbalance problem and to leverage the optimum datasize dynamicity in a dataflow framework, we present an algorithm which automatically partitions the application workspace. By putting this partitioning into the purview of the dataflow runtime system, we can adaptively change the size of databuffers and correctly balance the load. Experiments with four applications show that our technique allows developers to skip the tedious and error-prone step of manually tuning the data granularity. Our technique is always competitive with the best-known data partitioning for these experiments, and can beat it under certain constraints.

The primary objective of university education is to provide students with the required information and skills to enable them to make a successful contribution to the national development effort. In order to evaluate the level of expertise and skill of students, this preparation includes frequent examination and appraisal in the form of tests. Manual exams are carried out by most universities;Post Graduate and Under Graduate in India. Due to multiple uses made of the outcomes of the students, these examinations have high stakes. Consequently, the experiments became subject to different types of malpractice. Test malpractice affects the success of students in exams and leaves the scores/grades earned inaccurate, hence a challenge to examination bodies and the nation's education system (India). These are all disturbing signs that pose a danger to the nation. Examination malpractice has eaten deep into the Indian culture of education. Therefore, the object of this paper is to explore the problem of examination malpractice in India. The paper covered relevant measures, procedure setting/implementation and suggestions for this action. And finally, a model is proposed to stop malpractices in the examination. This IoT based model is used for detecting any metallic object or object in a range more than normal IR proximity sensor range. The block diagram of proposed model and circuit diagram for that model discussed in detail. This proposed model may be used for any investigation in the universities examinations. © 2021 Elsevier Ltd. All rights reserved.

There is a possibility of remaining indication of microorganisms on Martian subsurface and therefore, a robotic arm mounted on an exploration robot is required to dig to a certain depth and collect appropriate sample to be analyzed. However, the environment on the surface of Mars is harsh and most of all, limited power is available from the solar panel. In this paper, FEMI (Force-and-Energy Manipulability Index) is proposed to evaluate a feasible arm configuration for low energy consumption in its soil sampling operation. FEMI is calculated by the combination of an energy manipulability of an arm and an external force generated at an end effector of the arm. The FEMI derives the most feasible configuration on the joint angles of the arm for each sampling point. The usefulness of the FEMI is confirmed through a numerical simulation of a robotic arm. The simulation also presents that the FEMI can be used to obtain mechanical parameters of the arm such as link length and motor power, that are optimally-designed for a certain mission.
