Carbon Emission Characteristics of Railways
Rail transportation plays a crucial role in reducing carbon emissions from the transportation system, making a significant contribution to environmental impact mitigation due to the efficiency of passenger and freight rail transportation. Estimates of greenhouse gas (GHG) emissions impacts into the atmosphere are intrinsically linked to the modernization of transportation system, due this sector still heavily relies on fossil fuels, such as gasoline and diesel. In the context of studying GHG emissions and their life cycle, it is common to assess different alternatives to identify the most sustainable options. For example, when comparing different transportation systems, one can analyze not only the direct emissions from vehicles but also emissions associated with the manufacturing, maintenance, and operation of infrastructure such as roads, rails, or airports

LiDAR Calibration in Data Collection Vehicles
Accurately calibrating camera–LiDAR systems is crucial for achieving effective data fusion, particularly in data collection vehicles. Data-driven calibration methods have gained prominence over target-based methods due to their superior adaptability to diverse environments. However, current data-driven calibration methods are susceptible to suboptimal initialization parameters, which can significantly impact the accuracy and efficiency of the calibration process. Precise calibration is essential for achieving accurate data fusion between LiDAR and camera sensors. In general, calibration approaches can be classified into four categories: target-based approaches, feature matching-based approaches, statistics-based approaches, and deep learning-based approaches.

Daytime and Overnight Joint Time-Varying Charging
The objective is to minimize the total charging costs of all BEBs. Two important factors, i.e., peak–valley price and time-varying charging power, are considered to depict real-world charging situations.  Numerical results show that compared with the existing first come, first serve rule-based charging solution, the charging schedule obtained by solving the established model via the CPLEX solver can save 7%–8% of BEB charging costs. Hence, our model could be applied to improve the BEB charging schedule in practice.

Excelsior (Smack)
Excelsior is an authentically restored fishing smack of the Lowestoft fishing fleet and a member of the National Historic Fleet. She was built by John Chambers of Lowestoft in 1921 and worked until 1936 before being converted into a motor coaster. In 2021 Excelsior will celebrate her 100th birthday. During her time as a motor coaster she was known as Svinør and worked mainly in Norwegian waters before returning to Lowestoft in 1972. She measures 23 metres (75 ft) long with a beam of 5.9 metres (19 ft) and is ketch rigged and is the last traditional sailing trawler able to tow a full-sized traditional trawl net. Excelsior was restored in 1989 and operates as a sail training vessel based out of Lowestoft, able to accommodate up to 17 people, including 12 trainees or passengers.

French Cruiser Foch
Foch was the third unit of the Suffren class. She entered service in 1931 and spent the interwar period in the Mediterranean. September 1939 found her still in Toulon. She participated in the search for the Graf Spee in the Atlantic before returning to Toulon. The only time she fired her guns in anger was during the bombardment of Vado, Italy in mid-June 1940. She was at Toulon at the time of the Franco-German Armistice in June 1940. She remained at Toulon until the French Fleet there was scuttled in late November 1942. She was subsequently raised by the Italians who scrapped her in 1943-44. She was originally to be named Lavois after the Marquis de Lavois, the Minister of War under King Louis XIV. However, Marshall Ferdinand Foch, France's most famous soldier during the First World War died on 29 March 1929 one month before her launch. She was then renamed Foch in his honour. The main gun turrets were named after places that were associated with Marshall Foch during the Great War.

Integrating Short Sea Shipping with Trans-European Transport Networks
A numerical model of transport networks is used to support the calculation of the main parameters driving transport decisions, for multiple pairs of origin/destination representing statistical regions of the European Union, and for different, alternative intermodal and unimodal transport chains. Results are presented using a geographic information system. This approach is applied in a case study dedicated to the evaluation of the competitiveness of transport chains based on short sea shipping between Portugal and The Netherlands, integrated with other components of Trans-European Transport Networks (rail freight corridors and inland waterways), compared to road haulage-based transport chains.

La Noumbi
La Noumbi is a floating production storage and offloading (FPSO) unit operated by Perenco. The vessel, converted from the former Finnish Aframax crude oil tanker Tempera by Keppel Corporation, will replace an older FPSO unit in the Yombo field off the Republic of Congo in 2018. Built at Sumitomo Heavy Industries in Japan in 2002, Tempera was the first ship to utilize the double acting tanker (DAT) concept in which the vessel is designed to travel ahead in open water and astern in severe ice conditions. Tempera and her sister ship Mastera, built in 2003, were used mainly to transport crude oil, year-round, from the Russia n oil terminal in Primorsk to Neste Oil refineries in Porvoo and Naantali. In 2015, Neste sold Tempera to the oil and gas company Perenco for conversion to an FPSO.

Vehicle and Powertrain Efficiency of Long-Haul Commercial Vehicles
On-road transportation of freight is central to modern economic activity. However, current on-road freight vehicles emit significant amounts of greenhouse gas emissions (GHGs), on the order of 7% of global anthropogenic emissions, along with significant amounts of local and regional air pollutants. Mitigating CO2 emissions from long-haul commercial trucking is a major challenge that must be addressed to achieve substantial reductions in greenhouse gas (GHG) emissions from the transportation sector. Extensive recent research and development programs have shown how significant near-term reductions in GHGs from commercial vehicles can be achieved by combining technological advances.

Freeway Traffic Breakdown Using Artificial Neural Networks
Traffic breakdown is the transition of traffic flow from an uncongested state to a congested state. On freeways, when a large number of on-ramp vehicles merge with mainline traffic, it can cause a significant drop in speed and subsequently lead to traffic breakdown. Therefore, ramp meters have been used to regulate the traffic flow from the ramps to maintain stable traffic flow on the mainline. However, existing traffic breakdown prediction models do not consider on-ramp traffic flow. An algorithm based on artificial neural networks (ANN) is developed to predict the probability of a traffic breakdown occurrence on freeway segments with merging traffic, considering temporal and spatial correlations of the traffic conditions from the location of interest, the ramp, and the upstream and downstream segments.
