This article provides an overview of heavy metal contamination in rivers and assessment methods of their contamination and effects. According to literature, rivers with heavy metal contamination in surface water are mainly found in developing countri

This paper proposes a systematic approach for the design of a general class of analog infinite-impulse-response (IIR) filters, which includes all well-known classical analog filters as a special case. All specifications including the conventional one

For a transfer function F(ejω) of order n, Kalman-Yakubovich-Popov (KYP) lemma characterizes a general intractable semi-infinite programming (SIP) condition by a tractable semidefinite programming (SDP) for the entire frequency range. Some recent re

Analog filters constitute indispensable components of analog circuits. Inspired by recent advances in digital filter design, this paper provides a flexible design for analog filters. All-pole filters have maximally flat passband, so our design minimi

This paper proposes a novel method to design exactly linear phase infinite impulse response half-band filters with arbitrary regularity. Broadly speaking, the design problem is formulated as a semi-infinite program, which is then turned into a semide

This paper proposes a novel method to design two-channel filter banks composed of exactly linear phase IIR filters. Broadly speaking, the design problem is formulated as a semidefinite program (SDP) of minimal order such that the computational comple

Bounding the sidelobe and mainlobe levels of an array with complex weights is attractive in that it allows direct control of the radiation pattern. In this paper we propose an efficient beamforming technique for synthesizing the patterns of large arr

Antenna array pattern synthesis with mask constraints can be formulated as a convex optimization problem with semi-infinite trigonometric polynomial constraints. The current approach uses a Linear Matrix Inequality (LMI) characterization of the semi-
