On rough maximal operators and Marcinkiewicz integrals along submanifolds
(2009 , Article)We investigate the LP boundedness for a class of parametric Marcinkiewicz integral operators associated to submanifolds and a class of related maximal operators under the L(log L)α(Sn-1) condition on the kernel functions. ... -
On secure communication over the Z-Channel
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)The discrete memoryless Z-Channel (DM-ZC) with a confidential cross-message is considered. Three messages are transmitted; encoder 1 transmits one message to be decoded by decoder 1. Encoder 2 transmits two messages, the ... -
On sexual dimorphism in the shrimp Palaemon pacificus (decapoda: palaemonidae) Collected from the red sea
( Qatar University , 1994 , Article)Palaemon pacificus is common in the Red Sea coast and the sexes are separate. Potential sexual dimorphism in 38 morphological parameters was investigated in a population of Palaemon pacificus collected from the Red Sea ... -
On sizing the required energy of HVDC based inertia emulation for frequency control
( IEEE Computer Society , 2018 , Conference Paper)This paper presents a novel approach on analysis and evaluation of required energy for emulating virtual inertia of HVDC interconnected system for stabilizing the frequency deviations. Presented study is in the scheme of ... -
On Softwarization of Intelligence in 6G Networks for Ultra-Fast Optimal Policy Selection: Challenges and Opportunities
( Institute of Electrical and Electronics Engineers Inc. , 2022 , Article)The emerging Sixth Generation (6G) communication networks promising 100 to 1000 Gbps rates and ultra-low latency (1 millisecond) are anticipated to have native, embedded Artificial Intelligence (AI) capability to support ... -
On Some Properties of Multiplicative Topological Indices in Silicon-Carbon
( Hindawi Limited , 2021 , Article))e use of graph theory can be visualized in nanochemistry, computer networks, Google maps, and molecular graph which are common areas to elaborate application of this subject. In nanochemistry, a numeric number (topological ... -
On Some Shrinkage Techniques For Estimating The Parameters Of Exponential Distribution
( Qatar University , 1986 , Article)A variety of shrinkage methods have been proposed for estimation of some unknown parameter by considering estimators based on a prior guess of the value of the parameter. We compare some of the shrunken estimators for the ... -
On some statistical approximation by (p, q)-Bleimann, Butzer and Hahn Operators
( MDPIAG , 2018 , Article)In this article, we propose a different generalization of (p, q)-BBH operators and carry statistical approximation properties of the introduced operators towards a function which has to be approximated where (p, q)-integers ... -
On Some Tintinnids (Protozoa : Ciliata)From The Strait Of Hormoz And The United Arab Emirates Waters
( Qatar University , 1995 , Article)An examination of plankton samples collected from the oceanic waters of the Strait of Hormoz and the UAE inshore and offshore waters revealed the presence of a diverse community of planktonic Tintinnida (Protozoa). 38 ... -
On spectrum sharing between energy harvesting cognitive radio users and primary users
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)This paper investigates the maximum throughput for a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU) plugged to a reliable power supply. The SU maintains a finite energy queue and harvests ... -
On Stability in Multiobjective Integer Linear Programming: A Stochastic Approach
( Qatar University , 2006 , Article)In this paper we consider a multiobjective integer linear stochastic programming problem individual chance constraints. We assume that there is randomness in the right-hand sides of the constraints only and that the random ... -
On stability of equilibrium points in nonlinear fractional differential equations and fractional Hamiltonian systems
( Wiley Periodicals, Inc.� , 2014 , Article)In this article, a brief stability analysis of equilibrium points in nonlinear fractional order dynamical systems is given. Then, based on the first integral concept, a definition of planar Hamiltonian systems with fractional ... -
On strongly generalized convex stochastic processes
( Taylor and Francis Ltd. , 2022 , Article)In this paper, we introduce the notion of strongly generalized convex functions which is called as strongly η-convex stochastic processes. We prove the Hermite-Hadamard, Ostrowski type inequality, and obtain some important ... -
On Symboloic Reasoning and Direct Inference Principle
( Qatar University , 2004 , Article)This paper discusses an approach using the M-valued symbolic logic with syllogistic reasoning and direct inference principle (reasoning from statistical information to conclusions about individuals), to manipu¬late statistical ... -
On target coverage in mobile visual sensor networks
( Association for Computing Machinery, Inc , 2014 , Conference Paper)Recent advancements in manufacturing low-cost wireless battery operated cameras has made their application in Wireless Video Sensor Networks (WVSN) increasingly more feasible and affordable. The application of robotic ... -
On the 'independence of trials-assumption' in geometric distribution
( Taylor & Francis, Ltd , 2008 , Article)In this note, it is shown through an example that the assumption of the independence of Bernoulli trials in the geometric experiment may unexpectedly not be satisfied. The example can serve as a suitable and useful classroom ... -
On the Achievable Degrees of Freedom of a Relay Aided X-Channel
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)In this paper, we investigate the effect of a relay on the Degrees of Freedom (DoF) of a single input single output (SISO) X-channel with no channel state information at transmitters (CSIT). In contrast to previous work, ... -
On the Achievable Rates of OFDM with Common Phase Error Compensation in Phase Noise Channels
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Article)This paper considers the problem of analytically assessing the maximum achievable rates (capacity) of orthogonal frequency division multiplexing (OFDM) transmissions when the receiver, for complexity reasons, only accounts ... -
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
