Smart pollution monitoring approaches based on wireless sensor networks (WSNs) have progressed significantly over the past decade. More recently, intelligent computational strategies based on internet-of-things (IoT) and cloud computing (CC) have gained much momentum in the related studies. In this study, a smart context-aware environmental pollution monitoring and control scheme is presented for an urban setting to demonstrate how effective pollution mitigation and control can be achieved by the integration of known hardware and software approaches in a feedback control system. As a main contribution, this work shall describe in detail how the hardware infrastructure that consists of internet-of-things (IoT) and either cellular or non-cellular communications, is combined with machine learning (ML) software algorithms to provide informed environment control decisions/signals for dynamically and optimally updating the status of our environmentally controlled mitigation strategies. Finally, the importance of this work is clear as the framework and architecture can also be applied to other urban settings and mitigation strategies that can be optimized using intelligent and context-aware control signals.

In this work, we propose a new local optimization method to solve a class of nonconvex semidefinite programming (SDP) problems. The basic idea is to approximate the feasible set of the nonconvex SDP problem by inner positive semidefinite convex approximations via a parameterization technique. This leads to an iterative procedure to search a local optimum of the nonconvex problem. The convergence of the algorithm is analyzed under mild assumptions. Applications to optimization problems with bilinear matrix inequality (BMI) constraints in static output feedback control are benchmarked and numerical tests are implemented based on the data from the COMPL e ib library.

This paper describes the core of a video signal processor dedicated to perform MPEG-2 motion estimation and prediction selection. A mixed Hardware/software approach based on a small RISC controller was adopted which gives flexibility and robustness in the choice of the algorithms. Hardware optimizations were investigated to implement genetic motion estimation algorithm which appears to be the best candidate for this kind of architecture. The candidate motion vectors generated by the controller allow nearly full search quality with a drastic decrease of the required calculation power and the hardware complexity.

The decision of the controllability property of a nonlinear system is still not settled completely. For input-linear systems the well-known Lie algebra rank condition can be used. In this contribution we make use of this rank condition to compute the set of not locally controllable points of polynomial dynamical systems by algebraic methods.

A new rapid tooling (RT) system based on pre-placed metallic powder has been proposed. A 500 W Nd-YAG laser, a pre-placed powder mechanism, a linear planar motor based working table, and PC-based controller are incorporated for the hardware architecture. In this research, we propose a software technique that includes slicing with bucket sorting, direct slicing, and tool path generation algorithms. The slicing method provides the direct slicing of the CAD model in IGES geometric format to improve the accuracy of desired part. Effort was attempted to find out the better parameters of laser cladding using single clad and cladding layer techniques. The process of the proposed system involves path control, laser cladding of layer by layer, milling, and finishing. Based on the investigation, some metallic components were fabricated.

Self-driving technology is expected to revolutionize different sectors and is seen as the natural evolution of road vehicles. In the last years, real-world validation of designed and virtually tested solutions is growing in importance since simulated environments will never fully replicate all the aspects that can affect results in the real world. To this end, this paper presents our prototype platform for experimental research on connected and autonomous driving projects. In detail, the paper presents the overall architecture of the vehicle focusing both on mechanical aspects related to remote actuation and sensors set-up and software aspects by means of a comprehensive description of the main algorithms required for autonomous driving as ego-localization, environment perception, motion planning, and actuation. Finally, experimental tests conducted in an urban-like environment are reported to validate and assess the performances of the overall system.

Instruction scheduling methods based on the construction of state diagrams (or automata) have been used for architectures involving deeply pipelined function units. However, the size of the state diagram is prohibitively large, resulting in high execution time and space requirement. We present a simple method for reducing the size of the state diagram by recognizing unique paths of a state diagram. Our experiments show that the number of paths in the reduced state diagram is significantly lower-by 1 to 3 orders of magnitude-compared to the number of paths in the original state diagram. Using the reduced MS-state diagrams, we develop an efficient software pipelining method. The proposed software pipelining algorithm produced efficient schedules and performed better than R.A. Huff's (1993) Slack Scheduling method, and the original Co-scheduling method, in terms of both the initiation interval (II) and the time taken to construct the schedule.

By using small-sized, next-generation NVRAM (such as MRAM, FeRAM and PRAM) as a write buffer, we can improve the overall performance of the NAND flash memory-based storage systems. However, traditional address mapping algorithms in Flash Translation Layer (FTL) software were designed without any consideration of the existence of write buffer. In this paper, we propose a novel write buffer-aware flash translation layer algorithm, optimistic FTL, which is designed to harmonize well with NVRAM write buffers. Simulation results show that the proposed optimistic FTL outperforms previous log block-based FTL algorithms.

Empirical Wavelet Transform and Fano Equality Ratio Test-based Fault Detection Scheme for Inverter Dominated Autonomous Microgrid

作者： Ankan Chandra G K Singh Vinay Pant Electrical Engineering IIT Roorkee Roorkee India

Modern power systems must develop a suitable protection mechanism, in order to deal with the technical challenges associated with the integration of distributed generation (DG) into microgrid systems. Specifically, it was noticed that for inverter-dominated microgrid, when operates in autonomous mode, fault current exhibits very low magnitude due to inverter control and their low electromagnetic inertia, which makes the traditional protection techniques vulnerable. While addressing the aforementioned issues, a straightforward and fast protection method based on Empirical Wavelet Transform (EWT) and Fano equality ratio test-based statistical measurement is proposed in this article. To investigate the performance of the proposed scheme, a 14-bus looped microgrid test system containing PV and battery energy storage system is considered. Primarily, using EWT the multiresolution coefficient of fault current signals at both ends of the line is estimated, and then by implementing Fano equality ratio test the adequate threshold setting is set for the identification of fault. The modelling and simulation of the test microgrid system are carried out in PSCAD-EMTDC software, and the fault detection algorithm is formulated and executed in MATLAB R2022(a) which uses data obtained in PSCAD.
