In an accompanying paper submitted concurrently to this conference, we present our first complete version of a generic and modular software framework for intelligent computer-automated product design. The framework has been implemented with a client-server software architecture that automates the design of offshore cranes. The framework was demonstrated by means of a case study where we used a ...

An analog of the Falconer distance problem in vector spaces over finite fields asks for the threshold α > 0 such that |∆(E)| & q whenever |E| & q, where E ⊂ Fq , the d-dimensional vector space over a finite field with q elements (not necessarily prime). Here ∆(E) = {(x1 − y1) 2 + · · ·+ (xd − yd) 2 : x, y ∈ E}. The second listed author and Misha Rudnev ([4]) established the threshold d+1 2 , an...

In this paper, we claim that the operation schedule of automated stacking cranes (ASC) in storage yard container terminals can be built effectively and efficiently by using a crane dispatching policy, propose noisy optimization algorithm named N-RTS derive such policy efficiently. To select job for an ASC, our uses multi-criteria scoring function to calculate score each candidate weighted summa...

Abstract Media coverage of migrant and refugee camps often concerns not everyday life in camps, but violence or a camp's outright destruction. These portrayals risk inscribing into public memory as sites danger criminality, vulnerability without agency. What methods engaging with aftermath its representation might enable more complex understandings the reality camps? We engage camp site inscrip...

Background: Three-dimensional (3D) modeling and visualization of temporary site facilities is instrumental in revealing potential space conflicts and refining time and cost estimates. This research focuses on implementation of photo-based 3D modeling in a time-dependent, dynamically-changing context. Methods: We propose a cost-effective modeling technique to obtain dynamic dimension measurement...

The authors examined factors related to participation in walking, gardening or yard work, and sports or exercise in 686 community-dwelling adults 60-95 years of age from Wave IV of the population-based Americans' Changing Lives Study. Logistic regression revealed that male gender, being married, and better functional health were associated with greater likelihood of participating in gardening o...

The 6-min walk test (6MWT) is a common component of fitness assessments of older adults; however, differing course configurations might affect 6MWT performance. It is unclear how comparable 2 different configurations are. To determine the comparability of 2 courses, 35 adults >65 years of age completed two 6MWT, once walking around a 20- by 5-yd outdoor rectangle and once on an indoor oval trac...

The paper presents a laboratory model of the 3D tower crane. The arm of the crane is approx 1.2m long and the model is approx. 1.5m heigh. The crane is equipped with three DC motors that control: the rotary movement of the tower, the movement of the trolley and up and down movement of the load. The model is equipped with an unique unit for measuring an angle position of the load. The paper cont...

The natural sway of crane payloads is detrimental to safe and efficient operation. Under certain conditions, the problem is complicated when the payloads create a double-pendulum effect. Most crane control research to date has focused on single-mode dynamics. For example, several researchers have shown that signal-mode oscillations can be greatly reduced by properly shaping the inputs to the cr...

Lateral root formation is an important developmental component of root systems in vascular plants. Several regulatory genes for lateral root formation have been identified from recent studies mainly using Arabidopsis thaliana. In this study, we isolated two dominant mutant alleles, crane-1 and crane-2, which are defective in lateral root formation in Arabidopsis. The crane mutants have dramatic...
