In this paper we study various predicates concerning line transversals to lines and segments in 3D. We compute the degrees of standard methods of evaluating these predicates. The degrees of some of these methods are surprisingly high, which may explain why computing line transversals with finite precision is prone to error. Our results suggest the need to explore alternatives to the standard me...

Although vibration monitoring is a popular method to monitor and assess dynamic structures, quantification of linearity or nonlinearity of the dynamic responses remains a challenging problem. We investigate the delay vector variance (DVV) method in this regard in a comprehensive manner to establish the degree to which a change in signal nonlinearity can be related to system nonlinearity and how...

This study describes the weakening of intervocalic /s/ in the Nijmegen Corpus of Casual Spanish and investigates the role of several potential conditioning factors, including morphological, lexical and probabilistic variables. Three acoustic parameters were examined: voicing, the difference in high-band (4-8 kHz) intensity between /s/ and the following vowel, and the duration of the dip in low-...

We report a 20-year-old man who sustained lumbar fractures involving 5 vertebrae following a road traffic accident. He was initially treated non-operatively to allow multiple pedicles to heal. He developed post-traumatic kyphosis for which corrective osteotomy and posterior spinal instrumented fusion was performed. He achieved a good functional outcome. We emphasise the need for careful radiolo...

This study focuses on identifying accident-prone areas and analyzing the factors contributing to distribution of traffic accidents near highway ramps. A combined method kernel density estimation, spatial autocorrelation analysis, multivariate logistic regression analysis helped identify accident hotspots. Through data collection clustering characteristics in diversion merging were identified. F...

The purpose of this research is to find out and analyze the law enforcement against traffic accidents by police in jurisdiction Batang Resort Police. To know factors that hinder settlement accident casesin policies handle This study uses a sociological juridical approach, with descriptive analytical specification. data used are secondary obtained from literature study. were analyzed qualitative...

In this paper, two-state Markov switching models are proposed to study accident frequencies. These models assume that there are two unobserved states of roadway safety, and that roadway entities (roadway segments) can switch between these states over time. The states are distinct, in the sense that in the different states accident frequencies are generated by separate counting processes (by sep...

Photo-transduction in cone segments (CS) is crucial for high acuity daytime vision. For ill-defined reasons, CS degenerate in retinitis pigmentosa (RP) and in the transitional zone (TZ) of atrophic zones (AZ), which characterize geographic atrophy (GA). Our experiments confirm the loss of cone segments (CS) in the TZ of patients with GA and show their association with subretinal CD14(+)mononucl...
