A Truthful Auction for Green Continuous Task Allocation and Pricing in Edge Computing

A Truthful Auction for Green Continuous Task Allocation and ...

With the advent of edge computing, more and more tasks are offloaded to edge servers, but the computing and storage capabilities of edge servers are limited. Although some works propose efficient schemes for task allocation and pricing, they may ignore users' preferences for continuous tasks. However, the combinatorial preference causes high computational complexity. In this paper, we propose a dominant-strategy incentive compatibility (DSIC) and computationally efficient mechanism for green continuous task allocation based on the combinatorial auction. Besides, the activity on edge (AOE) network is introduced to describe the continuity of tasks. The proposed mechanism gives an approximate solution to the winner determination problem (WDP) in polynomial time and a pricing strategy that can guarantee the truthfulness and individual rationality of auction participants. We demonstrate the approximate ratio of the proposed algorithm through theoretical analysis. Experimental results show that the proposed mechanism achieves truthfulness, individual rationality, and high computational efficiency while considering green continuous task allocation.

A double HfZrO2 (HZO) ferroelectric field-effect transistor (FeFET) is demonstrated with ultra-low operating voltage as |VP/E| = 3 V to achieve multilevel cell (MLC) nonvolatile memory (NVM). Compared to a single FE-HZO FeFET, the metal/ferroelectric/metal/ferroelectric/Si (MFMFS) structure results not only in a reduction of VP/E, but also provides a feasible memory window (MW) of 1.9 V for MLC operation. In addition, the metal/ferroelectric/insulator/ ferroelectric/Si (MFIFS) FeFET exhibits a MW as high as >2.5 V. The double HZO FeFET has potential to improve power consumption and enhance memory density for MLC-NVM applications. © 2022 IEEE.

Using communications signals for dynamic target sensing is an important component of integrated sensing and communications (ISAC). In this paper, we propose to utilize the beam squint effect to realize fast non-cooperative dynamic target sensing in massive multiple input and multiple output (MIMO) Terahertz band communications systems. Specifically, we construct a wideband channel model of the echo signals, and design a beamforming strategy that controls the range of beam squint by adjusting the values of phase shifters and true time delay lines. With this design, beams at different subcarriers can be aligned along different directions in a planned way. Then the received echo signals at different subcarriers will carry target information in different directions, based on which the targets’ angles can be estimated through sophisticatedly designed algorithm. Moreover, we propose a supporting method based on extended array signal estimation, which utilizes the phase changes of different frequency subcarriers within different orthogonal frequency division multiplexing (OFDM) symbols to estimate the distances and velocities of dynamic targets. Interestingly, the proposed sensing scheme only needs to transmit and receive the signals once, which can be termed as You Only Listen Once (YOLO). Compared with the traditional ISAC methods that require time consuming beam sweeping, the proposed one greatly reduces the sensing overhead. Simulation results are provided to demonstrate the effectiveness of the proposed schemes. Copyright © 2023, The Authors. All rights reserved.

This paper presents an analysis of the electromagnetic fields (EMF) exposure to multiple sources in a classroom environment. The research is motivated by the increasing use of electronic devices in educational environments and the need to estimate this. The methodology used involves simulating a classroom with students using laptops, which are considered as the main sources of electromagnetic radiation. The 1g and 10 g peak spacial Specific Absorption Rate (psSAR) are calculated for different parts of the human body, including the head, back, and hands. The results indicate that the psSAR is higher in the back, followed by the head and hands. When the free distance between desks is 250 mm, two-fold at the hands to forty-five-fold at the back greater psSAR are obtained when comparing to just one student with his laptop.

This paper proposes a performance analysis of using a static volt-amp-reactive (VAR) compensator for a three-phase self-excited induction generator (SEIG) operating as a single-phase induction generator. The study proposes appropriate capacitor for building up voltage supplying power to load with static VAR for regulating terminal voltage. The simulation model is analyzed by using MATLAB/Simulink under various conditions such as reactive power supplied, dynamic response, steady state, building up voltage for startup, linear load, non-linear load and harmonics in system. From the study (based on the study, the findings revealed it is found) that using the static VAR compensator connected in parallel with loads for supplying reactive power to the load systems is needed for maintaining terminal voltage.

In this work, a systematic investigation of the effects of point defects on the efficiency of a Cu2ZnSnSe4 (CZTSe) thin film solar cell was conducted using temperature-/power-dependent photoluminescence (PL) and time-resolved photo-luminescence (TRPL). The studied stoichiometric CZTSe absorber layer for a CZTSe solar cell with an efficiency of 4.4 % was prepared using the low-toxicity selenization process. The fitting to the Arrhenius plot and the stretched tail at the long-wavelength side of PL spectrum obtained at 10 K indicated a high concentration of zinc on copper (CuZn) point defects. The dispersive-photon-energy-dependent TRPL at 10 K exhibited non-exponential stretched PL decay at all photon energies and, in particular, revealed the highly fluctuating potential of CZTSe that caused carrier localization. This effect was observed to be caused by [2CuZn− + SnZn2+] defect clusters, which produce a significant conduction/valence band-edge shift in their vicinity in CZTSe and can cause shunt leakage and an increase in series resistance. This systematic investigation presents the experimental characterization of [2CuZn− + SnZn2+] defect clusters and provides perspective to help clarify the performance deterioration of CZTSe solar cells. © 2023

Physical training for a person with an impaired hand generally requires extensive guidance and supervision from rehabilitation therapists. Currently, the advantages of wearable sensing technologies and the breakthrough performances of deep neural networks offer feasible solutions for developing assistive tools, particularly to automatically monitor the functional use of the patient’s hand. These applications help to report the results of a rehabilitation training, such as the interaction time between hands and objects and the number of interactions during each practice session. This reduces the burden on physiotherapists and occupational therapists and is beneficial for related research, such as rehabilitation assessment and cognitive sciences. However, the lack of datasets, particularly a dedicated dataset for rehabilitation training/exercises that are collected by body-worn sensors, can block these potential advantages. In this paper, we construct such a multimodal dataset and present a comprehensive study of relevant hand tasks using state-of-the-art deep neuronal models. The dataset is collected in a series of rehabilitation exercises of ten patients who are in treatment after injuries or strokes. The constructed dataset includes different wearable modalities such as cameras, accelerometers, and gyroscopes. Table-based exercises for rehabilitation of patients are designed with ball, water bottles, wooden blocks, and cylindrical blocks. In total, 56 exercise videos with more than 54 GB of data are collected. These videos are segmented into 431 sequences that present instances of each exercise at a certain time. To evaluate the performance of recent neuronal networks, we extract 4500 still images to label eight classes including left- and right-hand, and other objects involved in the exercises. In addition, labeling the patient’s hand in a consecutive frames of 40 shots is implemented with approximately 29K images annotated. These labeled datasets are utilized to

The characteristic mode analysis (CMA) is formulated and implemented for the hydrodynamic volume integral equation (HDVIE) that is used to mathematically model electromagnetic field interactions and conduction current dynamics on nanoantennas and nanoscatterers. The proposed method produces excitation-independent characteristic hydrodynamic currents and the corresponding modal significance curves, providing useful information that can be used to optimize the performance of a nanoantenna. Numerical results demonstrate the reliability and the applicability of the proposed approach.
