Where pigeonhole principles meet König lemmas

David Belanger, C.P. Chong, Wei Wang, Tin Lok Wong et autres

We study the pigeonhole principle for Σ 2 \Sigma _2 -definable injections with domain twice as large as the codomain, and the weak König lemma for Δ 2 0 \Delta ^0_2 -definable trees in which every level has at least half of …

On the computability of perfect subsets of sets with positive measure

C.P. Chong, Wei Li, Wei Wang, Yue Yang

A set X ⊆ 2 ω X \subseteq 2^\omega with positive measure contains a perfect subset. We study such perfect subsets from the viewpoint of computability and prove that these sets can have weak computational strength. Then we connect the existence of …

On the role of the collection principle for Σ⁰₂-formulas in second-order reverse mathematics

C.P. Chong, Steffen Lempp, Yue Yang

We show that the principle P A R T \mathsf {PART} from Hirschfeldt and Shore is equivalent to the Σ 2 0 \Sigma ^0_2 -Bounding principle B Σ 2 0 B\Sigma ^0_2 over R C A 0 \mathsf {RCA}_0 , answering one …

A Π¹₁-uniformization principle for reals

C.P. Chong, Liang Yu

We introduce a Π 1 1 \Pi ^1_1 -uniformization principle and establish its equivalence with the set-theoretic hypothesis ( ω 1 ) L = ω 1 (\omega _1)^L=\omega _1 . This principle is then applied to derive the equivalence, to suitable set-theoretic …

Fast Image Segmentation via Double-layer Infiltration

C.P. Chong, Fu-Chiang Chang, Jung-Hua Wang

In this paper, a novel method called double-layer infiltration (DLI) is presented to perform fast region-based image segmentation. The method mainly comprises two successive processes, namely updating the feature of each region followed by merging the immediate regions as their updated features …

The design of a high-resolution CMOS comparator

C.P. Chong, K.C. Smith

The authors describe the design of high resolution CMOS comparators by firstly presenting an analysis of comparators with and without the cross-multiplexed technique (XMT). Analytic formulas for the comparison time and the setup time of the comparator are derived. The comparison times …

An analog parallel-processing array for motion detection

C.P. Chong

The chip reported consists of an array of cells which functionally simulate the light-intensity-variation detecting neurons that exist in the retina of most highly developed animals. This chip performs motion detection using sub-nanoampere differentiation of the output currents of photodiodes arranged in …

On the accuracy of image velocity computation using delay lines

C.P. Chong, C.A.T. Salama, Kaleigh Smith

Describes the accuracy and limitations of the image velocity computational technique based on delay lines. Three major sources of computational error are identified, namely, the image-area quantization, signal refraction, and delay-line mismatch. Computational errors obtained experimentally are discussed.>

A CMOS current comparator with well-controlled hysteresis

C.P. Chong, K.C. Smith

A CMOS current comparator with well-controlled hysteresis is described. The current comparator allows bidirectional input currents. Experimental results show that the current comparator takes approximately 300 ns to resolve a 2 mu A difference of input and threshold currents.>

Three-input amplifiers

C.P. Chong, K.C. Smith, Z.G. Vranesic

Two analog-circuit-building blocks, called the three-input amplifier and the complementary three-input amplifier, are described. The three-input amplifier may be configured directly to have a gain of one-half, and may also be used as a voltage summer. The complementary three-input amplifier may be …
