The document discusses ensuring functional safety for machine learning-based autonomous systems. It proposes using checksum algorithms to detect errors in matrix-matrix multiplication, a key computation. The solution was evaluated on sequential and AVX-based multiplication, finding that checksums can achieve 100% diagnostic coverage with minimal performance impact depending on matrix size. Future work includes evaluating multiple bit errors and accelerators.
Black Box Model based Self Healing Solution for Stuck at Faults in Digital Ci...IJECEIAES
The paper proposes a design strategy to retain the true nature of the output in the event of occurrence of stuck at faults at the interconnect levels of digital circuits. The procedure endeavours to design a combinational architecture which includes attributes to identify stuck at faults present in the intermediate lines and involves a healing mechanism to redress the same. The simulated fault injection procedure introduces both single as well as multiple stuck-at faults at the interconnect levels of a two level combinational circuit in accordance with the directives of a control signal. The inherent heal facility attached to the formulation enables to reach out the fault free output even in the presence of faults. The Modelsim based simulation results obtained for the Circuit Under Test [CUT] implemented using a Read Only Memory [ROM], proclaim the ability of the system to survive itself from the influence of faults. The comparison made with the traditional Triple Modular Redundancy [TMR] exhibits the superiority of the scheme in terms of fault coverage and area overhead.

Efficient decentralized iterative learning tracker for unknown sampled data i...ISA Interchange
In this paper, an efficient decentralized iterative learning tracker is proposed to improve the dynamic performance of the unknown controllable and observable sampled-data interconnected large-scale state-delay system, which consists of NN multi-input multi-output (MIMO) subsystems, with the closed-loop decoupling property. The off-line observer/Kalman filter identification (OKID) method is used to obtain the decentralized linear models for subsystems in the interconnected large-scale system. In order to get over the effect of modeling error on the identified linear model of each subsystem, an improved observer with the high-gain property based on the digital redesign approach is developed to replace the observer identified by OKID. Then, the iterative learning control (ILC) scheme is integrated with the high-gain tracker design for the decentralized models. To significantly reduce the iterative learning epochs, a digital-redesign linear quadratic digital tracker with the high-gain property is proposed as the initial control input of ILC. The high-gain property controllers can suppress uncertain errors such as modeling errors, nonlinear perturbations, and external disturbances (Guo et al., 2000) [18]. Thus, the system output can quickly and accurately track the desired reference in one short time interval after all drastically-changing points of the specified reference input with the closed-loop decoupling property.
5 Techniques to Achieve Functional Safety for Embedded SystemsAngela Hauber
Failures of safety-critical electronic systems can result in loss of life, substantial financial damage or severe harm to the environment.
Safe computer systems are typically used in avionics or railway applications requiring particularly high reliability. This also goes for the medical market, while industrial automation environments demand more and more functional safety as technology becomes readily available.

Online and Offline Testing Of C-Bist Using Sramiosrjce
Built-in self test techniques constitute a class of schemes that provide the capability of performing atspeed
testing with high fault coverage hence; they constitute an attractive solution to the problem of testing
VLSI devices. Concurrent BIST schemes perform testing during the circuit normal operation without imposing a
need to set the circuit offline to perform the test; therefore they can circumvent problems appearing in offline
BIST techniques. In this brief, a novel input vector monitoring concurrent BIST architecture has been presented,
based on the use of a SRAM-cell like register for storing the information of whether an input vector has
appeared or not during normal operation. The evaluation criteria for this class of schemes are the hardware
overhead and the CTL, i.e., the time required for the test to complete, while the circuit operates normally. The
simulation results shown to be more efficient than previously proposed Concurrent BIST techniques in terms of
hardware overhead and CTL.
The RaPId Toolbox for Parameter Identification and Model Validation: How Mode...Luigi Vanfretti
RaPId is a recursive acronym for Rapid Parameter Identification. The toolbox was built within WP3 of the FP7 iTesla project. It uses Modelica models compiled in FMUs compliant with the FMI standard, which are imported into Simulink using the FMI Toolbox for Matlab/Simulink from Modelon. Within the Matlab environment, we have developed a plug-in architecture that lets the user choose many different (or even their own) optimization solvers for parameter calibration. Not to mention, you can choose any simulation solver available in Simulink (not just trapezoidal integration!)

Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.

Editor's Notes
Ikerlan Technology research centre,
Use of diagnostic techniques in the Matrix-matrix multiplication (MMM) loops to compute an Execution Signature (ES).
Compiler: ARM v8 gcc (without optimization)
Compiler: MSVC2018 (without optimization)
1’s complement require the addition of the data to be protected and subsequently adding the carry bit back into the result. Arithmetic operations with AVX instructions have not carry bit
The reason is that , although the values of A,B,C are summarized with independent checksums, the final ES is obtained by combining these variables and the single bit-errors are masked.
Implementing XOR in the internal loop varies from 52.5% DC in unbalanced matrix L1 to only 0.9 % DC in the L2 matrix dimension.
