Approximate computing is a computational model targeted at high speed, low power execution of error-resilient applications. In this paper, we design and implement the RTL model of four variants of $8times 8$ booth and modified booth (Radix2) multipliers using 2 different designs of approximate 4:2 compressors. Matlab models of the variants are implemented and compared with the RTL models based on three quality metrics namely mean error distance (MED), mean relative error distance (MRED), and normalized mean error distance (NMED). RTL models of the multipliers are implemented using Verilog and synthesized using Xilinx Zynq-7000 FPGA from Xilinx as the target device. The different variants are compared in terms of the quality metrics, resource utilization, delay and power dissipation. The comparison shows that our implementation gives similar performance in terms of delay and resource utilization with lower error rate as that of state-of-the-art implementations.

For improved flight stability, the flight controller needs to compute precise attitudes of the quadrotor at a fast update rate. This paper provides a comparison between different sensor fusion algorithms for estimating attitudes using an Inertial Measurement Unit (IMU), specifically when the accelerometer gives erroneous readings. Three test cases with an emphasis on the influence of external acceleration on attitudes are selected. For each test case, noise filtered data from the IMU is streamed into four algorithms, namely Complementary, Kalman, Madgwick, and Mahony fusion filters. Furthermore, each algorithm is implemented on ESP32 (XtensaOR 32-bit LX6) microcontroller to benchmark the execution time. The estimated attitudes show that the Madgwick filter mitigates the effects of accelerations the most, while the Kalman filter and Mahony filter are robust to vibrations introduced to the system.

In this paper, we examine the challenges of groundwater data flow management due to institutional barriers and constraints through technology. We load the groundwater statistics from end-systems towards Distributed Data Storage (DDS) and the blockchain (BC), implementing a dual hashing procedure through Infura gateways and smart contracts. The smart contracts, logical code, and functions give control over access and file sharing. With data secured through crypto puzzles, the quality and integrity are increased while simultaneously preventing higher fee charges for storage on BC with reduced cost and time.

The motive of using multicore processors in real time systems, is due to power requirement, processing speed and a heavy integration trend. Failing to meet the timing constraints in real time systems can lead to catastrophic results. So, every task in a real-time system has to be mapped and scheduled to meet the deadlines and utilize the system resources efficiently. Different measurable parameters, in each of the priority based scheduling mechanisms and type of application is identified. The simulation of varied time critical system is carried out for timing analysis using priority based approaches of task scheduling. The extensive experimentation of log uniform random task sets, indicates that there is a necessity of a multi objective task scheduling mechanism for real time systems. The partitioned approach of scheduling in priority based schedulers is desirable to achieve reliability in multicore real time systems.

In today’s world, there is rapid change in lifestyle and the workload is also increasing. There is a high need to create a tool which will monitor the physical and mental health of a person during daily life. Stress and fatigue level of an individual can be monitored by recording parameters like Temperature, Heart Rate, ECG, and Galvanic Skin Response of hand or foot (GSR) over a period of time. In this paper we have proposed a machine, which will help in attendancei marking of students and also help in the health checkup process, by recording health parameters from connected sensors (temperature, heart rate, SPO2) and also capture front face videos, and then take out features and analyse the face emotions to help us to detect stress or any signs of depression in the student.

The paper presents a novel design potentiostat and read-out amplifier circuits for glucose sensing. The performance of proposed design is evaluated by using a power supply of 1.5 V in Semi-Conductor Laboratory (SCL) 0.18 $mu$m CMOS technology. There are two main advantages of the proposed design. First is reference voltage required across sensor reference electrode and working electrode, which is supplied by MOS transistors threshold voltage and the second is multioutput transconductance amplifier (MTA) programmable gain which is enhanced by transconductance (gm) boosting technique. It is useful to readout small magnitude sensor current. The proposed design is found suitable for the glucose concentration measurement from 50 mg/dl to 225 mydl. It is observed that the linear range is found for the sensor current from 40 nA to 210 nA i.e. electrode resistance from 6 M$Omega$ to 30 M$Omega$ approximately. The maximum power consumption of the proposed design is 124 $mu$Watt.

Fog computing is a system framework, distributed in nature and reduces latency in data communication between the Internet of Things (IoT) and cloud networks. The present state of the art focuses on the data communication and incorporation of blockchain in fog networks. Very few researches are there on the creation of fog networks and there exists no systematic study to estimate fog resources for the IoT sensor traffic. In this paper, we have theoretically modelled the requirement of fog resources for the sensor traffic in the IoT system, in terms of System Utility estimation using the Queueing theory model. We have embedded the miner nodes of the blockchain framework with the fog layer to make the whole network transparent to all the users. Here, we have performed an experimental analysis based on the proposed framework(fog miner) to determine the system response time and performed simulation using the IFogSim simulator to estimate the energy consumption of the framework. We also estimate the influence of sensor nodes addition on the system utility for the proposed framework. The experimental and theoretical analysis emphasises the scalability issues of the framework and it gives better performance than the present state of the art research.

This is a demo abstract based on our previously published article [1]. Some of the significant challenges of central cloud systems and the blockchain include lack of scalability, security risks and higher energy consumption. As a solution, an application with an off-chain Interplanetary File System (IPFS) distributed storage system is presented as CoviChain. The IPFS is used for storing and hashing different data formats of various sizes into immutable links. The links are passed through smart contracts of the Ethereum blockchain to provide a double hash guarantee, along with user access permissions.

Smart healthcare is an important and emerging sector which gained a lot of significance with advanced technology. Continuous monitoring and timely reporting of health conditions is a key factor for diagnosing as well as treating the disease at early stages. This is accomplished with the development of IoT (Internet of Things) enabled smart healthcare assistance. Once medical data is stored in cloud it allows remote access and data sharing. The intelligent analysis is performed on the vital signals and communicated through smart Apps. This gives an end-to-end solution for smart healthcare. The main impact of this research is that patients can use the developed smart App for real-time health monitoring with future predictions via their mobile phones. This paper presents smart system with integration of IoT, Cloud Computing (CC) and Machine Learning (ML) techniques for early prediction of health abnormality.

Inexact computation is used extensively in image processing applications especially in compact devices where battery (power consumption) and size (area) must be used efficiently. Inexact computation uses accuracy as a design specification to enhance our need for speed and performance with limited resources and time. This paper introduces a novel multiplier that aims to fulfill this need of high performance with minimal hardware. An error correcting module is introduced to improve the accuracy of the proposed multiplier. Experimental results are carried out resulting in an improvement of 30% power consumption with a reduction of 36% area when compared against existing multipliers with acceptable accuracy. A huge improvement in delay can also be observed as a direct consequence of the multiplier design structure.
