On the Achievable Secrecy Diversity of Cooperative Networks with Untrusted Relays
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Article)Cooperative relaying is often deployed to enhance the communication reliability (i.e., diversity order) and consequently the end-to-end achievable rate. However, this raises several security concerns when the relays are ... -
On the aero acoustic and internal flows structure in a centrifugal compressor with hub side cavity operating at off design condition
( Elsevier , 2016 , Article)This paper covers the characterization of the acoustic noise and the unsteady flow field of a high speed centrifugal compressor NASA CC3. In order to accurately predict the noise, all analyses are carried out through the ... -
On the applicability of 2D local binary patterns for identifying electrical appliances in non-intrusive load monitoring
( Springer , 2021 , Conference Paper)In recent years, the automatic identification of electrical devices through their power consumption signals finds a variety of applications in smart home monitoring and non-intrusive load monitoring (NILM). This work ... -
On the application of αβ-transformation for power systems frequency relaying
( Institute of Electrical and Electronics Engineers Inc. , 2001 , Conference Paper)This paper presents a new and very accurate algorithm for power system frequency measurement. The proposed algorithm is based on αβ-transformation of the three phase voltages or current waveforms in the relay location, ... -
On the Average Secrecy Outage Rate and Average Secrecy Outage Duration of Wiretap Channels with Rician Fading
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)In this paper, we study important physical layer security metrics over wiretap channels with Rician fading. We derive the average secrecy outage rate (ASOR) expression to quantify the average secrecy zero level crossing ... -
On the basis number and the minimum cycle bases of the wreath product of some graphs II
( University of Zielona Gora , 2010 , Article)A construction of a minimum cycle bases for the wreath product of a star by a path, two stars and a star by a wheel is given. Moreover, the basis numbers of these products are determined. -
On the basis number of the wreath product of ladders
( Charles Babbage Research Centre , 2016 , Article)The basis number of a graph G is defined to be the least non negative integer d such that there is a basis B of the cycle space of G such that each edge of G is contained in at most d members of B. In this paper, we determine ... -
On the basis number of the wreath product of paths with wheels and some related problems
( Charles Babbage Research Centre , 2017 , Article)In this paper, we investigate the basis number for the wreath product of wheels with paths. Also, as a related problem, we construct a minimum cycle basis of the same. -
On the boundedness of a class of rough maximal operators on product spaces
(2011 , Article)In this paper, we study the Lp boundedness of a class of maximal operators T (γ) {Ωj} and a related class of rough singular integrals on product spaces. We obtain appropriate Lp estimates for such maximal operators and ... -
On the boundedness of rough oscillatory singular integrals on Triebel-Lizorkin spaces
( springer link , 2011 , Article)We obtain appropriate sharp bounds on Triebel-Lizorkin spaces for rough oscillatory integrals with polynomial phase. By using these bounds and using an extrapolation argument we obtain some new and previously known results ... -
On the capacity of cooperative diversity systems with adaptive modulation
( IEEE , 2005 , Conference Paper)In recent years, cooperative diversity systems have gained increased attention in the literature as a new way of combating the effect of signal fading. In this paper, we investigate the performance of these systems when ... -
On the coexistence of a primary user with an energy harvesting secondary user: A case of cognitive cooperation
( John Wiley and Sons Ltd , 2016 , Article)In this paper, we consider a cognitive scenario where an energy harvesting secondary user shares the spectrum with a primary user. The secondary source helps the primary source in delivering its undelivered packets during ... -
On the complex relationship between different aspects of social capital and group loan repayment
( Elsevier , 2020 , Article)Do all aspects of social capital improve repayment behavior in group lending programs? The group lending literature typically uses one or few measures of social capital in a linear form, and systematically understates the ... -
