Chapter
Full-text available
Our exploratory research study’s main objective is to analyze the technical digitalization requirements of 60 commercial contracts signed with Romanian Small and Medium Size Enterprises from the field of Services, Healthcare and Manufacturing, in order to assess the context, process improvement, order, and perceived importance of digitizing 9 main...
Article
In this paper we present a set of good practices in the design of a security-centric architecture for a Communication Channel that can be used to secure a Loosely-Coupled distributed platform, over unreliable communication mediums. The proposed practices are derived from designing a complete architecture that is modular and designed to support prin...

This article proposes a non-standard complex problem of Partitioning and Vehicle Routing Problem (PVRP), that assumes an infinite capacity for vehicles and demands that routes will have the least possible time discrepancy. The problem was presented in a real-life scenario, with real constraints and motivations for requirements. Current established...

Due to being scalable, easily cacheable, and well-suited for high-traffic web applications, RESTful APIs are highly used today, hence in this paper, we present a selective review of how the security evolved around APIs and how Machine Learning (ML) and Artificial Intelligence (AI) techniques have been used in developing new solutions for testing, m...

This article presents the architecture, design and validation of a microservice orchestration approach, that improves the flexibility of heterogeneous microservice-based platforms. Improving user experience and interaction, for time-critical applications are aspects that were primary objectives for the design of the architecture. Each microservice...

This article presents the architecture, design and validation of an orchestration approach, that improves the flexibility of Service based platforms. Improving user experience and interaction, for time-critical applications are aspects that were primary objectives for the design of the architecture. Each Service can provide its own embedded User In...
Chapter
Full-text available
This article presents the architecture, design and validation of a distributed learning approach, that provides support for knowledge preservation. The architecture is able to provide support for Collaborative Data Mining, Context Aware Data Mining, but also Federated Learning. Improving User Experience, providing support for research activities an...
Conference Paper
Full-text available
Async Messaging Systems tend to be ubiquitous nowadays. Their major drawback, however, lays in the limited usability with classic REST API's, that cannot be easily integrated inside such a platform, but are readily available in all major programming languages. This article proposes an alternate approach, which is the design of an Ontology Driven Se...
Chapter
Full-text available
Far from being a hype, cybersecurity is one of the most important aspects of our daily lives. Gaining trust in a cyber system is not an easy task, as problems and security hazards can be willingly or unwillingly introduced in it. This paper describes a security-centric architecture of the communication bus in loosely coupled heterogeneous systems....
Chapter
Full-text available
Reducing the carbon footprint of our daily activities, as a race, is one of the most important priorities that we can have today. Optimizations play a key role in this process, as just swapping one fuel with another is not enough. An important part of managing and engineering a sustainable and economical transportation system, specifically in the f...
Chapter
Full-text available
The article presents MELODIC/FUNCTIONIZER platform, developed to support serverless deployment. It is a complete cross-cloud, cloud-agnostic deployment platform with advanced, utility-based optimization and multi-layer and real time monitoring features. This platform exploits the modelling language CAMEL, which advances the state-of-the-art through...

In the family of Intelligent Transportation Systems (ITS), Multimodal Transport Systems (MMTS) have placed themselves as a mainstream transportation mean of our time as a feasible integrative transportation process. The Global Economy progressed with the help of transportation. The volume of goods and distances covered have doubled in the last ten...
Chapter
Full-text available
This article presents an application for face recognition, which takes its video input streamed from smart glasses through an internet connection. The application resides in the cloud and uses serverless technologies. The system has been tested on a database of 1119 individuals and the results show that the classical serverfull architecture is from...
Chapter
Full-text available
The article presents an analysis of seven crossover operators for continuous spaces applied for Diploid Genetic algorithms (DGA). Unlike the classical ones, called in genetic “haploid” in which an individual is synonym with a chromosome, the individuals of DGA carry two chromosomes, which brings in intrinsic diversity in the population. The impact...

Chapter
The present article presents the research for optimizing a real-life instance of heterogeneous vehicle routing problem, used intensively by shipping companies. The experiments have been carried out on the data provided by real companies, with constrains on the number and capacity of the vehicles, minimum and maximum number of stops for each route,...
