An insect brain computational model inspired by Drosophila melanogaster: architecture description
2010
The fruit fly Drosophila melanogaster is an extremely interesting insect because it shows a wealth of complex behaviors, despite its small brain. Nowadays genetic techniques allow to knock out the function of defined parts or genes in the Drosophila brain. Together with specific mutants which show similar defects in those parts or genes, hypothesis about the functions of every single brain part can be drawn. Following these experiments, a computational model of the fly Drosophila has been designed with a view to its robotic implementation.
Los poetas ciegos y la ceguera en la poesía árabe: algunos casos destacados
2013
This paper deals with the verses of some relevant and famous blind Arab classical poets that talked about their blindness like the cases of al-A‛¿à, Ba¿¿ār ibn Burd and Abū-l-ɈAlā¿ al-Ma‛arrī among others. The study shows how each one of them faced his disability and the influence that their blindness had on their poetic production. This paper contains also the translation from the Arabic and tha analysis of the verses inspired by blindness to some seeing poets of Granada and the moderm Arabic poetry. El artículo se ocupa de los versos de algunos poetas árabes ciegos que se han hecho famosos en la literatura árabe clásica y que nos hablan de la ceguera como es el caso de al-A‛ à, Ba ār ibn …
A System-based View of Blockchain Governance
2023
Abstract CONTEXT Governance is crucial in achieving the success and sustainability of blockchain systems. However, blockchain governance is multi-faceted, complex, dynamic, and challenging due to its decentralized nature and automatically enforced rules and mechanisms. OBJECTIVES This study aims to advance the theory of blockchain governance and support practitioners to deepen the researchers’ and practitioners’ understanding of blockchain governance. METHODS The study is a systematic literature review of 75 articles that applies systems theory to conceptualize blockchain governance as a system and parsimoniously organize its interrelated elements into a conceptual model. RESULTS The paper …
Nonlinear Feedback Control and Stability Analysis of a Proof-of-Work Blockchain
2017
In this paper a novel feedback controller and stability analysis of a blockchain implementation is developed by using a control engineering perspective. The controller output equals the difficulty adjustment in the mining process while the feedback variable is the average block time over a certain time period. The computational power (hash rate) of the miners is considered a disturbance in the model. The developed controller is tested against a simulation model with constant disturbance, step and ramp responses as well as with a high-frequency sinusoidal disturbance. Stability and a fast response is demonstrated in all these cases with a controller which adjusts it's output at every new blo…
An Energy Blockchain, a Use Case on Tendermint
2018
The recent advances in distributed energy systems require new models for exchanging energy among prosumers in microgrids. The blockchain technology promises to solve the digital issues related to distributed systems without a trusted authority and to allow quick and secure energy transactions, which are verified and cryptographically protected. Transactions are approved and subsequently recorded on all the machines participating in the blockchain. This work demonstrates how users, which are nodes of the energy and digital networks, exchange energy supported by a customized blockchain based on Tendermint. We focus on the procedures for generating blocks and defining data structures for stori…
A Peer-to-Peer Market Algorithm for a Blockchain Platform
2020
In an era of technological revolution in which everything becomes smarter and connected, the blockchain can introduce a new model for energy transactions able to grant more simplicity, security and transparency for end-users. The blockchain technology is characterized by a distributed architecture without a trusted and centralized authority, and, therefore, it appears as the perfect solutions for managing exchanges between peers. In this paper, a market algorithm that can be easily transferred to a smart contract for maximizing the match between produced and consumed energy in a micro-grid is presented. The algorithm supports energy transactions between peers (both producers and consumers) …
Consequences of applying new technologies to sources of law (overview)
2020
Technological change has a very significant impact on the functioning of a lawyer. It is not only an advocate, judge, adviser or notary public with a law, but also specialized software in which the law is incorporated. The quality of this software, safety but also the certainty of its correctness is very important for legal certainty and functioning of lawyers. Modern law is not only the text of legal acts or contracts but also IT codes in which the law is incorporated (for example, smart contract). The law is controlled by the courts. The question arises as to who will control the codes in which the law is written. In the EU, only a few countries have recognised this problem when creating …
Aggregation and remuneration in Demand-Response with a blockchain-based framework
2020
This paper describes the possibility to use the blockchain technology for load and generation aggregation in a new distributed Demand Response (DR) service and customers remuneration system. The blockchain technology and the use of smart contracts for DR allow the creation of a distributed system in which customers can communicate directly, in a transparent, secure and traceable way, with the grid operator to provide their flexibility. In this paper, the DR problem formulation takes into account several aspects, which are periodically executed. First, the blockchain records customers’ energy consumption or production, then, the smart contract starts calculating the baseline and the potentia…
Whole-Genome Analyses
2014
Abstract Average nucleotide identity (ANI) was proposed almost 10 years ago as a means to compare genetic relatedness among prokaryotic strains. It was found that values around 95% corresponded to the 70% DNA–DNA hybridization cut-off value that is widely used to delineate archaeal and bacterial species. ANI calculations are one of the many aspects and approaches that can be derived from comparative genomic data and used for taxonomic purposes. Here, an overview about the impact and current usage of ANI values is given together with details of the existing user-friendly package tool, the biology-oriented software package JSpecies, which can be used to generate two types of ANI calculations …
An empirical evaluation of business model canvas in software startups : a team perspective
2019
Business model canvas is a commonly used tool among software startups. The tool aims to help companies develop business models and new strategies. Even though the model has been widely adapted among software startups a lack of scientific research regarding the topic can be found. This thesis evaluates how the business model canvas should be further devel- oped when it comes to early stage software startups. This is done with a team perspective. First, an understanding of software startups is created. Secondly, based on the literature the Team Component is presented including the con- structs of resources, networks, self-organization and way of working. After this, the scope is widened to bu…
