Handover and Uplink Power Control Performance in the 3.84 Mcps TDD mode of UTRA Network
2003
In this article we consider the performance of the 3.84 Mcps time-division duplex (TDD) mode of UTRA (Universal Terrestrial Radio Access) network. We emphasize two of the radio resource management algorithms, handover and uplink power control, whose role in the overall system performance is studied extensively. First, a handover algorithm used in WCDMA (Wideband Code Division Multiple Access) standard is considered in a TDD-mode operation. This gives rise to a careful setting of different handover parameters, and the evaluation of the effects to the system performance. Secondly, the specified uplink power control algorithm is considered. Since it is based on several user-made measurements w…
Optimized Handover Algorithm Based on Stackelberg Games in CBTC Systems for Urban Rail Transit
2014
Communications Based Train Control (CBTC) systems have become indispensable for train operation to improve the safety and efficiency of train running to the utmost extent at present. In this paper, the problem of train handover in wireless LAN of CBTC systems for urban rail transit was taken into consideration, which was formulated as a market competition with Stackelberg games and cooperative diversity to obtain the reasonable resource allocation for trains. Under the environment of continuous train-to-wayside communications with high reliability, the successful train handover probability was analyzed in detail. Firstly, the relay triggering during handover was introduced, and the price st…
Pacientu pārvešanas standartizācija no kardioķirurģijas zāles uz bērnu intensīvās terapijas nodaļu
2019
Maģistra darba tēma – Pacientu pārvešanas standartizācija no kardioķirurģijas zāles uz bērnu intensīvās terapijas nodaļu.

N-quantum approach to quantum field theory at finite T and mu: the NJL model
1999
We extend the N-quantum approach to quantum field theory to finite temperature ($T$) and chemical potential ($\mu$) and apply it to the NJL model. In this approach the Heisenberg fields are expressed using the Haag expansion while temperature and chemical potential are introduced simultaneously through a generalized Bogoliubov transformation. Known mean field results are recovered using only the first term in the Haag expansion. In addition, we find that at finite T and in the broken symmetry phase of the model the mean field approximation can not diagonalize the Hamiltonian. Inclusion of scalar and axial vector diquark channels in the SU(2)$_{rm f}$ $otimes$ SU(3)$_{\rm c}$ version of the …
Handover performance in the IEEE 802.16 mobile networks
2012
The IEEE 802.16 standard provides a full mobility support for stations moving across cell borders. In addition, the WiMAX Forum Network Working Group defines a set of procedures to support handovers in the mobile access network. One of the main characteristics of mobility support is fully controlled and optimized handover (HO), in which a mobile station (MS) migrates from the air interface of one base station (BS) to another one. It is vital to keep the BS transition phase as short as possible to decrease delays and data loss, which is especially crucial for real-time applications, such as VoIP. In this paper we analyze ASN-anchored mobility performance and provide advisable handover relate…
Statistical learning and multiple linear regression model for network selection using MIH
2014
Award of Appreciation; International audience; A key requirement to provide seamless mobility and guaranteeing Quality of Service in heterogeneous environment is to select the best destination network during handover. In this paper, we propose a new schema for network selection based on Multiple Linear Regression Model (MLRM). A horough investigation, on a huge live data collected from GPRS/UMTS networks led to identify the Key Performance Indicators (KPIs) that play the most important role in the handover process. These KPIs are: Received Signal Code Power (RSCP), received energy per chip (Ec/No) and Available Bandwidth (ABW) of the destination network. To extract a handover model from col…
La decisione della Cassazione sul caso Carola Rackete: note a margine
2020
Nell’ambito delle operazioni di salvataggio di 53 migranti-naufraghi, eseguite il 12 giugno 2019 in acque internazionali (al largo della Libia) dall’imbarcazione “Sea Watch 3” dell’omonima ong tedesca, la comandante Carola Rackete, al fine di portare a conclusione tali operazioni, chiede ripetutamente alle autorità italiane l’autorizzazione allo sbarco dei soccorsi nel porto di Lampedusa, individuato quale “luogo sicuro”, in inglese “place of safety” (“pos”). Dopo aver segnalato un continuo peggioramento delle condizioni psico-fisiche dei migranti a bordo, la “Sea Watch 3” trasgredisce dapprima il divieto di ingresso in acque territoriali e, nella notte del 29 giugno, dopo una ulteriore fas…
Inclusive Design for Alzheimer’s Disease: Low-cost Treatments, Design and ICT
2019
Inability to acquire new memories, difficulty to remember recent events and to recognize objects, places and people, visual-spatial disorientation, these are some of the disorders with which who is affected by neurological diseases must learn to live with. In a continuously evolving society, where the decreasing birth rate and the drops in mortality are consistent, the job of Architecture is precisely to interpret the requirements and needs of people who have lost the canonical relationship with the world and give them the possibility to recover it or maintain it through communication channels that use their remaining ability to understand. The indoors and outdoors acquire a “prosthesis fun…

Persona, doveri e diritti in Luigi Sturzo
2004
Sturzo fissava la base della giustizia naturale nella coesistenza dei diritti e nella reciprocità dei doveri. La relazione presentata al seminario internazionale fa emergere l'influenza tomistica e rosminiana sul sociologo calatino che ha considerato cardini della società la dignità della persona e il bene comune.
