The independent life of the individuals suffering from Alzheimer's disease (AD) is compromised due to their memory loss, and as a result they always depend on someone by their side to help them lead their daily life. In this situation, generally, either the family members or the caregivers extend their helping hands; they attach notes on every single object or take out the contents of a drawer, the family might need to make those visible when they leave the patient alone at home. The goal of this study is to provide some helping means for the patient and the family members through existing science and technology. This study reports preliminary results on an Ambient Assisted Living (AAL) realtime system, achieved through Internet of Things (IoT) and Augmented Reality (AR) concepts, to fulfil this goal. The system has two main sections: the first one is the smartphone or windows application that allows caregivers/family-members to monitor a patient’s status at home and be notified if patient are at risk. The second part allows patient to use smart glasses to recognize QR codes in the environment and receive information related to the tags in the form of audio, text or three-dimensional image. This work presents preliminary results and investigates the possibility of implementing such a system.

A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Understanding Inductive Bias in Machine LearningSUTEJAS
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.

PV MODULE MODELPV cell model
Photovoltaic modules consist of a number of silicon based
photovoltaic cells electrically connected in series and in parallel
circuits, depending on the voltage or current requirements
A photovoltaic cell consists of a p-n junction that emits electrons
when exposed to light, which is known as photovoltaic effect. The
solar cell can be modeled as a current source which represents the
solar irradiation, in parallel with a forward biased diode.

Solution !
Numerical methods such as the Newton Raphson’s method have been
widely applied to solve this equation. A different approach is made in
order to establish an explicit form of this equation. When a Taylor series
is utilized to represent the function f(x)= ex as a power series, the
approximation will be:
If the same Taylor series representation is used for this equation, taking
into account only the first two parts of the series (first order
approximation - FOA), the PV module output current can be determined
by solving the following equation, Assuming that RS is given by the PV
module manufacturer or otherwise previously determined and RP = ∞
