A systems analysis of empty container logistics: a case study of Melbourne, Australia
No full textContainerised freight is a key component of global and urban trade. Empty containers are a necessary outcome of such trade and have operational costs close to that of full containers yet are not a source of revenue as the latter is. A literature review revealed regional repositioning to be a complex problem due to a multitude of interacting parts and distributed decision making among stakeholders which have conflicting objectives. The goal is to optimise the activities related to urban goods movements and reduce the total social cost of these activities. The purpose of this study is to develop a detailed description and understanding of the empty container movements in Melbourne using a modelling approach designed to represent complex systems. This paper explores the cause and effects of the land-side empty container repositioning. Then the key characteristics of the system were captured into a conceptual model that documents and articulates the logistics processes, interactions, power-relations, problems and potential solutions of the freight system. The conceptual model was translated into a simulation model in the form of an agent-based model. The agent-based model was a proof-of-concept which provided an opportunity to graphically imitate the logistics processes and interactions of the system in a natural, flexible and dynamic way. Empty containers represent a sizeable proportion of logistics activity, however previous studies on container freight operations in Melbourne have tended to focus on commercially valuable, loaded containers - not empty containers. This paper closes the gap in understanding of empty container management in Melbourne as represented in a concept model and agent-based model
Exploring Co-Modality Using On-Demand Transport Systems
No full textAbstractIntegrating passenger and freight transport systems, known as co-modality, is becoming more feasible due to recent developments in information and communication technologies (ICT) such as smart phones and global position systems (GPS). This paper uses simulation of an on-demand transportation scheme in which passengers and parcels can travel together to explore the benefits of co-modality when compared to existing schemes. It is shown that, depending on the demand, co-modality can provide improved experiences for both operators and passengers/customers
Letter from B.H. Thompson to Mary Thompson, August 6, 1848
No full textThe Free Soil Party Convention occurred in Buffalo on August 9 and 10, 1848. The convention was held to establish the new Free Soil party in an effort to prevent the extension of slavery into the Western Territories. The convention attracted upwards of 20 000 delegates, and the committee nominated former president Martin Van Buren for president. Although the party did not win the presidential election, they were successful in having 14 Congressmen and 2 Senators elected.A letter from B.H. Thompson, dated at Stanwix Hall, Albany, August 6, 1848, to Mary Thompson, New York. The letter describes Thompson’s trip from New York to Albany, and from there to Buffalo and Niagara Falls. He comments on the sites he expects to see on his trip, stating that “…I shall proceed to the falls, & probably have courage enough to pass both under & over the great cataract. Mr. Elliott has driven a pair of horse & carriage over his high (wire) suspension bridge, and surely a person after that may venture to walk over it. When I return, if my money holds out & my courage holds good, I may visit the Springs where the great, the powerful, the talented & the beautiful do annually congregate to while away a few idle hours, and spend a few useless dollars.” The St. Catharines mineral baths and salt springs became very popular around the middle of the 19th century, attracting the elite in Canada, as well as wealthy Americans
Metropolitan freight distribution by railways
No full textThis paper presents the results of a study on freight distribution by railway within a metropolitan area. The technical and economic feasibility analyses of freight distribution system have been supported by a methodology in which the main component consists of a modelling system developed to evaluate the urban/metropolitan freight demand. The study area is the Sorrentina Peninsula (one of the most famous tourist area in the middle-Italy, near Naples) that is well-known for its low-accessibility features from the freight distribution point of view

Clendenan-Thompson family fonds
No full textDaniel Clendenan (1793-1866) was the son of Abraham Clendenan, a private in Butler’s Rangers. He was married to Susan[na] [Albrecht ] Albright, daughter of Amos Albright. Daniel and Susan[na] had twelve children and belonged to the Disciple Church. In 1826 Daniel Clendenan purchased Part lot 14, Concession 6, Louth Township from Robert Roberts Loring. On this property he built a home and conducted the business of blacksmithing and along with William Jones operated a lumber mill. Volume 1 and the first part of Volume 2 are Daniel Clendenan’s account books. Daniel and his wife Susan are buried in the Vineland Mennonite cemetery. Daniel and Susan[na]’s youngest daughter, Sarah, married widower Andrew Thompson (1825-1901), son of Charles and grandson of Solomon. Andrew Thompson had settled in the Wainfleet area in 1854 and had owned a mill in Wellandport. Daniel Clendenan, in ill health, passed ownership of Lot 14, Concession 6, Louth Township to his son-in-law Andrew Thompson.
Robert Roberts Loring, the original owner of lot 14, concession 6 in Louth was born in September of 1789 in England. He joined the 49th Regiment of Foot as an ensign in December of 1804 and arrived in Quebec the following July. He served with Isaac Brock and Roger Sheaffe. In 1806 he was promoted to lieutenant. Loring was hired by Lieutenant General Gordon Drummond and accompanied him to Ireland in 1811, but the outbreak of war in the States in 1812 drew Loring back to Canada. On June 26, 1812 Loring became a captain in the 104th Regiment of Foot. On October 29 of the same year, he was appointed aide-de-camp to Sheaffe who was the administrator of Upper Canada. During the American attack on York in April 1813, Loring suffered an injury to his right arm from which he never recovered. In December of 1813, Drummond assumed command of the forces in Upper Canada and he appointed Loring as his aide-de-camp, later civil secretary and eventually his personal secretary.
Loring was with Drummond in 1813 at the capture of Fort Niagara (near Youngstown), N.Y. He was also with Drummond in the attacks on Fort Niagara, settlements along the American side of the Niagara River, and then York and Kingston. In July of 1814 he was promoted to brevet major, however he was captured at the Battle of Lundy’s Lane and he spent the remainder of the conflict in Cheshire, Massachusetts. One of his fellow captives was William Hamilton Merritt. Loring remained in the army and had numerous military posts in Canada and England. He retired in 1839 and lived the last of his years in Toronto. He died on April 1, 1848.

Urban freight transport and logistics: retailer’s choices
No full textThis paper presents a modelling system developed for the analysis of retailer’s choices in metropolitan areas. The proposed modelling system aims at analysing the aspects for freight shipments within urban or metropolitan areas. The models were developed using the results of some surveys carried out in different contexts characterised by a population between 180,000 and 800,000 inhabitants

Sweeping has no effect on renormalized turbulent viscosity
No full textWe perform renormalization group analysis (RG) of the Navier-Stokes equation in the presence of constant mean velocity field , and show that the renormalized viscosity is unaffected by , thus negating the ``sweeping effect", proposed by Kraichnan [Phys. Fluids {\bf 7}, 1723 (1964)] using random Galilean invariance. Using direct numerical simulation, we show that the correlation functions for and differ from each other, but the renormalized viscosity for the two cases are the same. Our numerical results are consistent with the RG calculations
