Abstract:

We consider a generalized form of the coupon collection problem in which a random number,S, of balls is drawn at each stage from an urn initially containingnwhite balls (coupons). Each white ball drawn is colored red and returned to the urn; red balls drawn are simply returned to the urn. The question considered is then: how many white balls (uncollected coupons) remain in the urn after thekndraws? Our analysis is asymptotic asn→ ∞. We concentrate on the case whenkndraws are made, wherekn/n→ ∞ (the superlinear case), although we sketch known results for other ranges ofkn. A Gaussian limit is o

Abstract:

Due to the injuries and inconvenience that picking balls caused, a number of ball pickup robot showed up in recent years. The existing ball pickup robots have a common problem that is they can’t complete the picking task at a fast speed for they are set to pick up all the balls. Put it another way, when facing multiple balls, their efficiency decreases to some extent. Different from their idea of picking all the balls, the new strategy in this paper aims to propose can balance efficiency and the degree of completion (picking enough balls) for the ball pick up robot.

Abstract:

The application of robotic systems is widespread in all fields of life and sport. Tennis ball collection robots have recently become popular because of their potential for saving time and energy and increasing the efficiency of training sessions. In this study, an unmanned and autonomous tennis ball collection robot was designed and produced that used LiDAR for 2D mapping of the environment and a single camera for detecting tennis balls. A novel method was used for the path planning and navigation of the robot. A fuzzy controller was designed for controlling the robot during the collection ope

Abstract:

Clay ball is a pavement surface defect which refers to a clump in which clay or dirt is mixed with hot asphalt mixture. Clay ball is typically caused by a combination of aggregate contamination of clay or soil, high aggregate moisture, and low production temperature at the asphalt plant. It usually appears a few weeks or months after paving under traffic load, after being liquefied and knocked from the pavement surface. Clay balls can be the source of potholing, raveling, and other issues such as moisture infiltration and reduced ride quality. This paper presents an investigation of the clay b

Abstract:

The sounds from pickleball have unique time and spectral characteristics. Each time a paddle strikes a ball, a pulse of sound is generated. The loudness of this impact depends on the paddles and balls used, the skill of each player, and the force of each impact. To understand the sound generated by different paddles and balls, a simple anechoic chamber was constructed for testing paddles and balls. A test procedure was created, and a data collection process was implemented. The test chamber was used to measure impact sounds with a constant ball speed. The time history and frequency content of

Sensors incorporated in a sports ball for data collection can affect the properties of a ball, specifically the spin rate of a ball if the mass distribution (moments of inertia, MOI) is altered. This paper provides a method for assessing the MOIs of a smart ball by means of spin rate data, collected from a gyroscopic sensor. The critical elevation angle of the angular velocity vector defines the separatrix condition, which decides whether the angular velocity vector precesses about the axis with the greatest MOI or with the smallest MOI. The critical elevation angle can be directly determined

Back pain is an inconvenience that is often found in pregnant women, especially pregnant women in the third trimester. Birth ball is a non-pharmacological therapy and is a simple physical therapy that uses a ball. Birth ball therapy can reduce back pain in third trimester pregnant women caused by significant weight gain and an enlarged stomach with increasing gestational age. The purpose of this study was to determine the effect of using a birthball on reducing low back pain in third trimester pregnant women. This study uses the one group pretest-posttest method by giving pretest to respondent

Abstract:

We consider a class of topological objects in the 3-sphere S3which will be called n-punctured ball tangles. Using the Kauffman bracket at A = eiπ/4, an invariant for a special type of n-punctured ball tangles is defined. The invariant F takes values in PM2×2n(ℤ), that is the set of 2 × 2nmatrices over ℤ modulo the scalar multiplication of ±1. This invariant leads to a generalization of a theorem of Krebes which gives a necessary condition for a given collection of tangles to be embedded in a link in S3disjointly. We also address the question of whether the invariant F is surjective onto PM2×2n

Abstract:

In the aerospace industry, bearing is widely used in various rotating machinery. The performance of bearing affects the operation of the whole machinery and even aviation equipment. The wrongly assembled ball due to size is an important reason for unqualified bearing. To solve this problem, an accurate ball detection method based on the bearing image is proposed. Firstly, according to the imaging characteristics of bearing and light propagation characteristics, an image collection system based on the coaxial light source is designed. Then, aiming at the problem that the embedded ball is occlud

Abstract:

Advancements in drilling technology are pivotal to optimizing the production and sustainability of oil and gas wells. One of the emerging innovations is the application of a specialized fluid known as “Fuzzy-ball” fluid. This paper comprehensively reviews the historical evolution and advancements in the utilization of fuzzy-ball fluid in drilling and well-repair processes. Fuzzy-ball fluid has been discovered to bolster a formation’s pressure-bearing capabilities and systematically augment resistance against oil, gas, and water flow. These attributes have been instrumental in the phased integr

Viscosity experiment is one of the materials given in the Basic Physics experiment course at FPMIPA UPI which aims to measure the viscosity level of a liquid using the Stokes law method or the ball viscosimetry method. Previously, oil was often used as a test material, but its thick color made observation of the ball in the liquid difficult, especially when using software such as trackers that require visual clarity. The purpose of this study was to examine the alternative of using teepol as a test material. The research method applied is the experimental method of replacing oil with teepol. F

Small ball inequalities have been extensively studied in the setting of Gaussian processes and associated Banach or Hilbert spaces. In this paper, we focus on studying small ball probabilities for sums or differences of independent, identically distributed random elements taking values in very general sets. Depending on the setting – abelian or non-abelian groups, or vector spaces, or Banach spaces – we provide a collection of inequalities relating different small ball probabilities that are sharp in many cases of interest. We prove these distribution-free probabilistic inequalities by showing
