In JPEG2000, the Cohen–Daubechies–Feauveau (CDF) 9/7-tap wavelet filter implemented by using the conventional lifting scheme has two problems. The first problem is that the filter coefficients are remaining complex; second, the conventional lifting scheme ignores image edges in the coding process. In this article, we propose an effective wavelet lifting scheme to solve these problems. For this ...

Alerting the driver of the speed limit is an important measure to keep the road safe. It is a challenging engineering problem to develop an automatic system which can detect speed limit signs under ever changing road conditions. In this paper, a robust algorithm for detecting speed limit sign is developed based on the traditional framework of pre-processing, feature extraction and detection. Th...

Given two functions f, g : {0, 1}n → {0, 1} a mapping ψ : {0, 1}n → {0, 1}n is said to be a mapping from f to g if it is a bijection and f(z) = g(ψ(z)) for every z ∈ {0, 1}n. In this paper we study Lipschitz mappings between boolean functions. Our first result gives a construction of a C-Lipschitz mapping from the Majority function to the Dictator function for some universal constant C. On the ...

Ultra-low-power circuits are becoming more desirable due to growing portable device markets and they are also becoming more interesting and applicable today in biomedical, pharmacy and sensor networking applications because of the nano-metric scaling and CMOS reliability improvements. In this thesis, three main achievements are presented in ultra-low-power adders. First, a new majority function...

The absolute loss is the absolute difference between the desired and predicted outcome. I demonstrate worst-case upper bounds on the absolute loss for the perceptron algorithm and an exponentiated update algorithm related to the Weighted Majority algorithm. The bounds characterize the behavior of the algorithms over any sequence of trials, where each trial consists of an example and a desired o...

We extend graded modal logic (GML) to a logic that captures the concept of majority. We provide an axiomatization for majority logic, MJL, and sketch soundness and completeness proofs. Along the way, we must answer the question what is a majority of an infinite set? Majority spaces are introduced as a solution to this question.

Social choice theory defines “preference aggregation” as forming collective preferences over a given set of alternatives. Likewise, “judgment aggregation” pertains to forming collective judgments on a given set of logically interrelated propositions. This paper extends beyond classical propositional logic into the realm of general multivalued logic, so that we can handle realistic collective de...

Background: Health science and technology today is a rapidly growing field. Health is a multifaceted concept influenced by several factors, and health literacy is essential to deal properly with the current situation. In this study, the association between health literacy and sexual function and sexual satisfaction were investigated in 2016. Materials and Methods: This descriptive and correlati...
