Classification of Solutions to the Minimum Energy Problem in One Dimensional Sensor Networks

2016

We classify of the minimum energy problem in one dimensional wireless sensor networks for the data transmission cost matrix which is a power function of the distance between transmitter and receiver with any real exponent. We show, how these solutions can be utilized to solve the minimum energy problem for the data transmission cost matrix which is a linear combination of two power functions. We define the minimum energy problem in terms of the sensors signal power, transmission time and capacities of transmission channels. We prove, that for the point-to-point data transmission method utilized by the sensors in the physical layer, when the transmitter adjust the power of its radio signal t…

Maximum Lifetime Problem in Sensor Networks with Limited Channel Capacity

2016

We analyze the maximum lifetime problem in sensor networks with limited channel capacity for multipoint-to-multipoint and broadcast data transmission services. For the transmission model in which the transmitter adjust the power of its radio signal to the distance to the receiver we propose a new Signal to Interference plus Noise Ratio function and use it to modify the Shannon-Hartley channel capacity formula. We show, that in order to achieve an optimal data transmission regarding considered the maximum lifetime problem we cannot allow for any interference of signals. For considered transmission model and the modified capacity formula we solve the maximum lifetime problem in one dimensiona…

Efectos del entrenamiento sensorimotor previo a la cirugía de artroplastia total en sujetos con osteoartritis de rodilla

2020

Introducción: El entrenamiento de fuerza y el sensorimotor son dos intervenciones comúnmente empeladas en sujetos con osteoartritis (OA) de rodilla. Sin embargo, una revisión sistemática de la literatura implementada como parte de este trabajo de tesis doctoral, reveló que la evidencia - especialmente en lo referente al entrenamiento sensorimotor - cuando se aplican en el periodo preoperatorio a la artroplastia total de rodilla (ATR), fue inconcluyente y no permitió extraer conclusiones sólidas sobre su efectividad en el postoperatorio temprano y tras un año de seguimiento. Objetivos: Estudiar los efectos derivados de implementar una intervención experimental preoperatoria, que combine el e…

LE PAROLE CHE INTENDONO L'INFINITO. BREVE FENOMENOLOGIA DELLA RICERCA VERITATIVA

2011

In un'epoca tarda come quella che viviamo, tutte le parole - anche quelle che intendono ed esprimono i mondi della vita quotidiana - sembrano diventare equivoche. Ciò ci consegna spesso ad una sorta di sonnambulismo esistenziale, in cui siamo costretti a parlare parole "parlate", che diventano logorate dall'uso, destinate a banalizzarsi. La scelta d'essere autenticamente desti può aiutarci a recurarare inl senso sorgivo delle parole: a intenderne il significato originario, che riempie di senso le nostre parole. Trovano in ciò fondamento di senso le parole poetiche, quelle metafisiche e quelle religiose...

Optimization of Delayed-State Kalman-Filter-based Algorithm via Differential Evolution for Sensorless Control of Induction Motors

2010

This paper proposes the employment of the differential evolution (DE) to offline optimize the covariance matrices of a new reduced delayed-state Kalman-filter (DSKF)-based algorithm which estimates the stator-flux linkage components, in the stationary reference frame, to realize sensorless control of induction motors (IMs). The DSKF-based algorithm uses the derivatives of the stator-flux components as mathematical model and the stator-voltage equations as observation model so that only a vector of four variables has to be offline optimized. Numerical results, carried out using a low-speed training test, show that the proposed DE-based approach is very promising and clearly outperforms a cla…

Famiglie biculturali: la soddisfazione familiare tra reti di supporto e comuntà

2011

Premessa L’immigrazione nel nostro Paese sembra identificarsi come un problema di convivenza o come un insieme di “nodi dolenti da risolvere” a livello sia politico-economico sia psico-sociale e relazionale. Le coppie miste o biculturali, formate da un partner autoctono ed uno straniero, consentono di ripensare la differenza come un valore aggiunto da cui trarre presupposti di crescita anche a partire dai microcontesti familiari (Ippolito, 2010). Scopo della ricerca La ricerca è finalizzata a comprendere la relazione tra soddisfazione familiare, sostegno sociale e senso di comunità in un gruppo di coppie miste. In particolare, si vuole studiare il peso che la rete primaria di sostegno e il …

UAV-Aided Secure Short-Packet Data Collection and Transmission

2023

Benefiting from the deployment flexibility and the line-of-sight (LoS) channel conditions, unmanned aerial vehicle (UAV) has gained tremendous attention in data collection for wireless sensor networks. However, the high-quality air-ground channels also pose significant threats to the security of UAV aided wireless networks. In this paper, we propose a short-packet secure UAV-aided data collection and transmission scheme to guarantee the freshness and security of the transmission from the sensors to the remote ground base station (BS). First, during the data collection phase, the trajectory, the flight duration, and the user scheduling are jointly optimized with the objective of maximizing t…
