Vecchi e nuovi problemi in tema di intervento dei creditori nell’esecuzione (note a margine di Cass. S.U. n. 61 del 7 gennaio 2014)
2015
Nel contributo in oggetto l'autore, muovendo dalla decisione delle Sezioni Unite della Cassazione n. 61 del 7 gennaio 2014, coglie l'occasione per riesaminare le vecchie e nuove problematiche sottese all’intervento dei creditori nel processo esecutivo. Il primo tema affrontato è quello della par condicio creditorum, che viene esaminata nella sua storia evolutiva dal Code Napoleon, al suo periodo di massima estensione, dato dal codice del 1940, fino al suo ridimensionamento a seguito delle riforme del 2005. Esamina quindi la possibilità del possibile superamento quoad effectum della distinzione tra intervento di creditori con titolo e senza titolo, alla luce delle evoluzioni della giurisprud…
Dynamic MAC Parameters Configuration for Performance Optimization in 802.11e Networks
2006
Quality of service support in wireless LAN is a theme of current interest. Several solutions have been proposed in literature in order to protect time-sensitive traffic from best-effort traffic. According to the EDCA proposal, which is a completely distributed solution, the service differentiation is provided by giving probabilistically higher number of channel accesses to stations involved in real-time applications. To this purpose, the MAC parameter settings of each contending stations can be tuned dynamically. In this paper, we face the problem of tuning the EDCA MAC parameters in common scenarios in which a given number of low-rate delay-sensitive traffic flows share the channel with so…
Remarks on IEEE 802.11 DCF Performance Evaluation, IEEE Communication Letters, Vol. 9, Issue 8, Aug 2005 pp:765 - 767
2005
This letter presents a new approach to evaluate the throughput/delay performance of the 802.11 Distributed Coordination Function (DCF). Our approach relies on elementary conditional probability arguments rather than bidimensional Markov chains (as proposed in previous models), and can be easily extended to account for backoff operation more general than DCF's one
On the accuracy of some common modeling assumptions for EDCA analysis
2005
Several models have been discussed in literature in order to evaluate the performance of the EDCA differentiation mechanisms. Despite of the exponential back off rules, usually the EDCA protocol has been modeled as a persistent slotted access protocol, and summarized into a set of access probabilities. These models often show a very different complexity and accuracy, according to the basis assumptions. In this paper, we propose a new modeling approach for EDCA, in which the medium access is described in terms of backoff counter comparisons, contention by contention, and no restrictive hypothesis is considered. Through our model, we verify the applicability of the most common protocol simpli…
Quality, Reliability, Security and Robustness in Heterogeneous Systems
2020
This book constitutes the refereed post-conference proceedings of the 15th EAI International Conference on Quality, Reliability, Security and Robustness in Heterogeneous Networks, QShine 2019, held in Shenzhen, China, in November 2019. The 16 revised full papers were carefully reviewed and selected from 55 submissions. The papers are organized thematically in tracks, starting with mobile systems, cloud resource management and scheduling, machine learning, telecommunication systems, and network management.
Bezastaino abinieku Anura sugu sastāvs un izplatība pilsētvides ūdenstilpēs Daugavpilī
2022
Mūsdienās abinieki pasaulē ir viena no visvairāk apdraudētām dzīvnieku klasēm. Visos pasaules reģionos ir konstatēta īpatņu skaita samazināšanās vai pilnīga izzušana. Abinieku izmiršanas cēloņi ir dažādi – biotopu pārveidošana, klimata izmaiņas, kā arī sēnīšu Batrachochytrium dendrobatidis izraisīta slimība. Abinieku izzušana ir skaidri redzama pateicoties bezastainajiem abiniekiem, jo tos var viegli gan ieraudzīt, gan saklausīt. Diemžēl šī problēma varētu skart arī Latvijas abiniekus. Bakalaura darba mērķis ir noteikt, kādas bezastaino abinieku sugas ir sastopamas Daugavpils ūdenstilpēs, kā arī noteikt aptuveno populācijas lielumu, pamatojoties uz pieaugušo varžu un krupju tēviņu dziesmu i…

Is Aquaponics Beneficial in Terms of Fish and Plant Growth and Water Quality in Comparison to Separate Recirculating Aquaculture and Hydroponic Syste…
2022
Aquaponics is a technique where a recirculating aquaculture system (RAS) and hydroponics are integrated to grow plants and fish in a closed system. We investigated if the growth of rainbow trout (Oncorhynchus mykiss) and baby spinach (Spinacia oleracea) would be affected in a coupled aquaponic system compared to the growth of the fish in RAS or plants in a hydroponic system, all systems as three replicates. We also investigated the possible effects of plants on the onset of nitrification in biofilters and on the concentration of off-flavor-causing agents geosmin (GSM) and 2-methylisoborneol (MIB) in rainbow trout flesh and spinach. For the fish grown in aquaponics, the weight gain and speci…
