This paper presents a comprehensive review of performancesecurity trade-off based on RANETs. It is suggested that stochastic Petri nets (SPNs) are the best choice to investigate performance-security trade-off in RANETs. In the context of RANETs, a mathematical model that is based on SPNs is analysed to investigate performance-security trade-off. Security is assessed in terms of mean time to sec...

By polling individual responses to hypothetical scenarios, valuation studies estimate population preferences toward health on a quality-adjusted life year (QALY) scale. The scenarios typically involve trade-offs in time (time trade-off (TTO)), risk (standard gamble (SG)), or number of persons affected (person trade-off (PTO)). This paper revisits the QALY assumptions and provides a coherent hea...

Allocating and routing problems in the field of transportation engineering are generally solved using the objective function of minimizing transport cost. Transport risk is a main concern in hazardous material transportation, mainly dependent on the vision of decision makers (national and/or local authorities). In this research work, a trade-off approach has been proposed to determine the safes...

Cryptanalytic time memory trade-off is a probabilistic algorithm for inverting a generic one-way function. Since its first introduction by Hellman, many variants and their analysis results have appeared. We present a new estimate for the success probability of the original Hellman trade-off, that is more accurate than the lower bound that is widely being used today.

During the development of an Real-time Database Management System (RTDBMS) one needs to trade-off between data consistency and timeliness. To achieve a systematic method for such trade-off, we must find a way to model the behaviors and properties of real-time transactions. In this report, we experiment with the modeling of transactions and verification of transaction properties in UPPAAL. We bu...

System spectral efficiency and user fairness are crucial aspects for resource allocation in multi-user OFDM-based cellular networks. This work intends to investigate the influence of the performance of packet scheduling algorithms on the trade-off between these two objectives in scenarios with non real-time and real-time services. By means of system-level simulations, we were able to create a d...

Time–cost trade-off problem is one of the main aspects of project scheduling. Due to variations in the real world, usually, risks in estimation of project parameters are considerably high. Therefore, use of uncertain models, which is capable of formulating vagueness in the real world, to solve time–cost trade-off problems, gives a scheduling with more stability against environmental variations....
