An Organizational View of Distributed Systems

The relationship between organization theory and distributed systems is studied. By viewing distributed systems as analogous to human organizations, concepts and theories germane to the management science field of organization theory can be...

Authentication in distributed systems

We describe a theory of authentication and a system that implements it. Our theory is based on the notion of principal and a “speaks for” relation between principals. A simple principal either has a name or is a communication channel; a com...

Optimistic recovery in distributed systems

Optimistic Recovery is a new technique supporting application-independent transparent recovery from processor failures in distributed systems. In optimistic recovery communication, computation and checkpointing proceed asynchronously. Synch...

A Distance Metric for Uneven Clusters of Unsupervised K-Means Clustering Algorithm

In this paper, we propose a new distance metric for the K-means clustering algorithm. Applying this metric in clustering a dataset, forms unequal clusters. This metric leads to a larger size for a cluster with a centroid away from the origi...

Battery Energy Storage Capacity Estimation for Microgrids Using Digital Twin Concept

Globally, renewable energy-based power generation is experiencing exponential growth due to concerns over the environmental impacts of traditional power generation methods. Microgrids (MGs) are commonly employed to integrate renewable sourc...

Synthetic biology open language (SBOL) version 3.1.0

Synthetic biology builds upon genetics, molecular biology, and metabolic engineering by applying engineering principles to the design of biological systems. When designing a synthetic system, synthetic biologists need to exchange informatio...

A Systematic Literature Review on Modern Cryptographic and Authentication Schemes for Securing the Internet of Things

The rapid integration of the Internet of Things (IoT) into healthcare ecosystems has revolutionized patient monitoring and data accessibility; however, it has simultaneously expanded the cyber-attack surface, leaving sensitive medical data ...

Real-Time Power Electronics Laboratory to Strengthen Distance Learning Engineering Education on Smart Grids and Microgrids

In the science and engineering fields of study, a hands-on learning experience is as crucial a part of the learning process for the student as the theoretical aspect of a given subject. With the COVID-19 pandemic in 2020, educational instit...

Experimentation in software engineering

A framework is presented for analyzing most of the experimental work performed in software engineering over the past several years. The framework of experimentation consists of four categories corresponding to phases of the experimentation ...

Recommendation Systems for Software Engineering

Software development can be challenging because of the large information spaces that developers must navigate. Without assistance, developers can become bogged down and spend a disproportionate amount of their time seeking information at th...

Resumen: Este documento contempla el diseño del Backbone MPLS para un ISP dentro del Distrito Metropolitano de Quito. Se exponen aspectos teóricos de la tecnología MPLS, tales como: los componentes físicos y funcionales, la estructura de un...

Video-based communication assessment for weight management counseling training in medical residents: a mixed methods study

Abstract Background Physician delivered weight management counseling (WMC) occurs infrequently and physicians report lack of training and poor self-efficacy. The purpose of this study was to develop and test the Video-based Communication As...

Lessons Learned From a Sequential Mixed-Mode Survey Design to Recruit and Collect Data From Case-Control Study Participants: Formative Evaluation

BackgroundSequential mixed-mode surveys using both web-based surveys and telephone interviews are increasingly being used in observational studies and have been shown to have many benefits; however, the application of this survey design has...

Statistics for people who (think they) hate statistics

Part I. Yippee! I'm in Statistics Chapter 1. Statistics or Sadistics?: It's Up to You Part II. Sigma Freud and Descriptive Statistics Chapter 2. Computing and Understanding Averages: Means to an End Chapter 3. Vive la Difference: Understand...

Introduction to Probability and Statistics

Used by hundreds of thousands of students since its first edition, INTRODUCTION TO PROBABILITY AND STATISTICS continues to blend the best of its proven coverage with new innovations. While retaining the straightforward presentation and trad...

CKMT1 Counteracts VDAC1 Oligomerization-Induced Neuronal Pyroptosis Through Steric Hindrance in Ischemic Stroke.

Propagation of solitons in optical fibers with generalized Kudryashov’s refractive index

The propagation of optical solitons in optical fibers with the generalized Kudryashov’s refractive index is described by a high order nonlinear Schrödinger equation. The main feature is that the amplitude and width of the pulse can be chang...

Effect of stress ball use before cholecystectomy surgery on surgical fear, anxiety and comfort of patients: a randomized controlled trial

Abstract Background Thinking about surgery generally causes fear and anxiety among patients. These negative feelings may affect the healing process. This study aimed to investigate the effects of a stress ball on surgical fear, anxiety and ...
