Utility–Privacy Trade-Offs with Limited Leakage for Encoder
Entropy, 2023 The utilization of databases such as IoT has progressed, and understanding how to protect the privacy of data is an important issue. As pioneering work, in 1983, Yamamoto assumed the source (database), which consists of public information and private ...

Waterfilling Theorems for Linear Time-Varying Channels and Related Nonstationary Sources
, 2016 The capacity of the linear time-varying (LTV) channel, a continuous-time LTV filter with additive white Gaussian noise, is characterized by waterfilling in the time-frequency plane.

Class of Analytic Function Related with Uniformly Convex and Janowski’s Functions
Journal of Function Spaces, 2018 In this paper, we introduce a new subclass of analytic functions in open unit disc. We obtain coefficient estimates, extreme points, and distortion theorem. We also derived the radii of close-to-convexity and starlikeness for this class.

On a new class of p-valent functions with negative coefficients defined by convolution
Le Matematiche, 2015 In this paper, we introduce a new class of analytic p-valent functions defined in the open unit disc by using convolution and obtain some results including coefficient inequality, distortion theorems, Hadamard products, radii of starlikeness and ...

Causal Rate Distortion Function on Abstract Alphabets: Optimal Reconstruction and Properties [PDF]
, 2012 A causal rate distortion function with a general fidelity criterion is formulated on abstract alphabets and a coding theorem is derived. Existence of the minimizing kernel is shown using the topology of weak convergence of probability measures.

Проблемы анализа, 2023 With the aid of 𝑞-calculus, this paper introduces a new generalized p𝑝, 𝑞q-Bernardi integral operator ℬ^𝑝 𝑛,𝑞𝑓p𝑧q. Then, we define a new subclass of harmonic p𝑝, 𝑞q-starlike functions of complex order associated with the operator ℬ^𝑝 𝑛,𝑞𝑓p𝑧q.

On Metric Ramsey-type Dichotomies
, 2002 The classical Ramsey theorem, states that every graph contains either a large clique or a large independent set. Here we investigate similar dichotomic phenomena in the context of finite metric spaces.

Some properties of a class of holomorphic functions associated with tangent function
Demonstratio MathematicaIn this study, we define new class of holomorphic functions associated with tangent function. Furthermore, we examine the differential subordination implementation results related to Janowski and tangent functions. Also, we investigate some extreme point
