The crystal structures of thetrans-fused compound potassiumtrans-bicyclo[5.1.0]octane-4-carboxylate monohydrate, K+·C9H13O2−·H2O, (I), and ofcis-bicyclo[5.1.0]octan-4-yl 4-bromobenzenesulfonate, C14H17BrO3S, (II), have been determined. Compound (I) represents the smallesttrans-fused cyclopropane structure known to date, and features the expectedshorteningof the bridging C—C bond relative to the other cyclopropane bond lengths, in contrast to thecis-fused system, (II), where all of the cyclopropane bond lengths are the same. The bicyclic ring system of (I) is disordered across a crystallographi

A group of bicyclic ketones and thiones have been synthesized for homenolization studies.

In other cases, although a concerted mechanism was observed, asynchronous transition states were involved.

In this paper, we consider decompositions of the complete graph on v vertices into 4-cycles with a pendant edge. In part, we will consider decompositions which admit automorphisms consisting of: (1) a single cycle of length v, (2) f fixed points and a cycle of length v − f, or (3) two disjoint cycles. The purpose of this thesis is to give necessary and sufficient conditions for the existence of cyclic, f-cyclic, and bicyclic Q-decompositions of Kv.

Abstract:
Abstract Off-Road bicycle suspension systems are beneficial because they dissipate vibrational energy and a lower vibration dosage can reduce the metabolic energy expenditure of the cyclist [1]. However, dampers dissipate energy and the energy dissipated must be compensated by additional input from the cyclist. Estimates of the energy dissipated range from 1–2% of the total power input by the cyclist [2–4]. Additionally, suspension systems add weight to a bicycle, which also requires additional energy when hill climbing and accelerating.

&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;Bicycle computers record and store global position data that can be useful for forensic investigations. The goal of this study was to estimate the absolute error of the latitude and longitude positions recorded by a common bicycle computer over a wide range of riding conditions. We installed three Garmin Edge 530 computers on the handlebars of a bicycle and acquired 9 hours of static data and 96 hours (2214 km) of dynamic data using three different navigation modes (GPS, GPS+GLONASS, and GPS+Galileo satellite systems) an

Abstract:
Test and modeling results are reported on a bicycle crankset with limited elasticity. Like record-breaking running shoes, the crank set has spring action which mitigates the effect of the dead zone during the pedal stroke. Fiber composite leaf springs are inserted inside the hollow carbon crank arms. The crank arms are not directly attached to the crank axle. Instead, sleeve bearings allow the crank arms to rotate by up to about five degrees relative to the crank axle. The rotation is counteracted by the springs and is proportional to applied torque at the pedals. The novel crank set and a con

Abstract:
Investing in sustainable, multimodal infrastructure is of increasing importance throughout the United States and worldwide. Cities are increasingly making strategic capital investment decisions about bicycle infrastructure—decisions that need planning efforts that accurately assess the equity aspects of developments, achieve equitable distribution of infrastructures, and draw upon accurate assessment methods. Toward these efforts, this project uses a granular bike network dataset with statistical and geospatial analyses to quantify a bike infrastructure availability score (i.e., bike score) th

Abstract:
Increased urbanization, population growth, and demand for time-sensitive deliveries means increased freight movement in cities, which contributes to emissions, noise, and safety concerns. One innovative mode gaining widespread attention for urban deliveries is cargo cycles—bicycles adapted for freight delivery. Despite the recognized potential and possible success of transporting at least 25% of freight via cycle, research remains limited. This research investigates the potential of cargo cycle delivery for last mile freight in Oakland, California, with a focus on the West Oakland neighborhood

Abstract:
The San Joaquin Valley is identified as an area with a high level of particulate matter (PM) in the air, reaching above the federal and state clean air standards (EPA 2019). Many of the cities in the valley are classified as the most polluted cities in the United States for both particulate matter and ozone pollution (American Lung Association, 2021). To resolve this issue, alternative forms of transportation have been considered in transportation planning. In this study, active transportation mode air quality was monitored on selected Woodward Park and Old Clovis trails and urban bike lanes.

Abstract:
The rapid growth in population and related demand for travel during the past few decades has had a catalytic effect on traffic congestion, air quality, and safety in many urban areas. Transportation managers and planners have planned for new facilities to cater to the needs of users of alternative modes of transportation (e.g., public transportation, walking, and bicycling) over the next decade. However, there are no widely accepted methods, nor there is enough evidence to justify whether such plans are instrumental in improving mobility of the transportation system. Therefore, this project re
