Multi Architecture Optimization of a Hybrid Electric Vehicle Using Object-Oriented Programming

2017

This article presents an energetic macroscopic representation multi-architecture model for hybrid vehicles using object-oriented programming. This approach is successfully used to evaluate the power performance and fuel consumption of different vehicles on different driving cycles. An optimization of power source sizing (ICE, EM and Battery) and system control, based on simulation results, is carried. Different architectures are compared for given cycles and optimization of hybrid architecture will also be possible.

Cell Association for MTC Devices in 5G Networks: Schemes and Performance Evaluation

2021

Fifth generation (5G) networks offer tremendous opportunities for Internet of things applications by facilitating massive machine-type communications (MTC). As many MTC devices are battery powered and intend to stay often in the sleep or power-saving mode, cell (re)association needs to be performed when a device wakes up. On the other hand, 5G networks are usually deployed as heterogeneous networks consisting of both macro and small cells under which a single device may be covered by multiple radio access technologies (RATs) simultaneously. Therefore, it is imperative to design effective cell association schemes for the purpose of efficient connectivity and resource utilization, especially …

Surfactant Association: Recent Theoretical and Experimental Developments

1991

A theoretical model describing the association of ionic surfactants into rod-shaped micelles is combined with an approximate formula for the viscosity increase induced by rod-shaped aggregates. It is shown that most of the thermodynamic parameters of the association model can be obtained from viscosity measurements. The approach is applied to micellar solutions of hexadecylpyridinium salts. The pronounced effect of counter-ion concentration on the growth of rod-shaped micelles can be attributed to a slightly higher degree of counter-ion association in the cylindrical part than in the end portions. An attempt is made to explain the finding that the degree of counter-ion association is virtua…

ROS/Gazebo Based Simulation of Co-operative UAVs

2019

UAVs can be assigned different tasks such as e.g., rendez-vous and space coverage, which require processing and communication capabilities. This work extends the architecture ROS/Gazebo with the possibility of simulation of co-operative UAVs. We assume UAV with the underlying attitude controller based on the open-source Ardupilot software. The integration of the co-ordination algorithm in Gazebo is implemented with software modules extending Ardupilot with the capability of sending/receiving messages to/from drones, and executing the co-ordination protocol. As far as it concerns the simulation environment, we have extended the world in Gazebo to hold more than one drone and to open a specif…

Cytoskeleton and Consciousness: An Evolutionary Based Review

2015

The fields of quantum biology and physics are now starting to unite to solve the mysteries associated with the field of evolutionary biology. One such question is the origination and propagation of consciousness which has always been ambiguous and in order to understand this concept, many theories have been proposed by several philosophers and scientists. This review paper agrees with the idea, that evolution is not a random process but hypothesizes, that its succession was managed by the expanding level of consciousness due to cell division and cell differentiation. Several theories propose that the cytoskeleton and its proteins are promoters for consciousness in the brain, which propagate…

The Semantics of Musical Topoi

2015

The article introduces an empirical approach to studying music’s extrinsic meanings, based on the idea of musical topos as a set of musical entities that is delimited and furnished with meaning by extramusical associations in a listener population. The proposed methodology involves free, associative responses as well as responses on semantic variables addressing the imagery. After deriving potential topical structures for a given musical domain from the quantitative results, the structures are substantiated by using them to guide a rule-based, qualitative analysis of the free responses. The approach allows a view to the topical organization of a musical domain in which the identity of each …

Therapeutic metaphors and personal meanings in group poetry therapy for people with schizophrenia

2021

This article concerns the therapeutic potential of metaphor in group poetry therapy, concentrating on the poetry therapy process of people diagnosed with schizophrenia. The data was collected in a one-year poetry therapy group. The main questions were: (1) What kind of therapeutic potential can metaphors offer in group poetry therapy? (2) What are the personal meanings and evaluations that the participants give to the therapy process and its effects on their lives? (3) What are the most significant elements in poetry therapy from the viewpoint of the client? The analysis was based on the Grounded theory method. The results showed that the most significant therapeutic factors of the process …

Reverse inheritance in statically typed object-oriented programming languages

2010

Reverse inheritance is a new class reuse mechanism, an experimental implementation of which we have built for Eiffel. It enables a more natural design approach, factorization of common features (members), insertion of classes into an existing hierarchy etc. Due to its reuse potential in Eiffel we consider exploring its capabilities in other industrial-strength programming languages like C++, Java and C#.

A study of LoRaWAN protocol performance for IoT applications in smart agriculture

2020

Abstract The use of Internet of Things (IoT) is becoming increasingly common in agribusiness to increase food production capacity for the expanding global population. Recently, low-power wide-area networks (LPWANs) have been used in the development of IoT applications that require low power consumption and low data transmission rates. LoRaWAN is considered the most suitable communication network for LPWANs for IoT applications in smart agriculture. In this paper, we present an in-depth study of the performance of the LoRaWAN communication network in the context of an IoT application for a pilot farm. We consider several scenarios and analyze simulation results by using Network Simulator 3. …
