Rapid Transit Automation And The Last Crew Member, Vukan R. Vuchic Oct 1973

Rapid Transit Automation And The Last Crew Member, Vukan R. Vuchic

Departmental Papers (ESE)

Rapid transit systems in many cities are being automated, but most transit officials reject the idea of operation without crews on the train as idealistic. At the same time large resources are spent on development of full automation for numerous new systems such as PRT, many of which have no defined role in urban transportation programmed train movement eliminates any possible improper driving practices. However, nearly all rapid transit vehicles have indirect controls which prevent the driver from improper acceleration and assist him in braking. Thus improvement through A TO is again not significant.

Skip-Stop Operation As A Method For Transit Speed Increase, Vukan R. Vuchic Apr 1973

Skip-Stop Operation As A Method For Transit Speed Increase, Vukan R. Vuchic

Departmental Papers (ESE)

Increase of transit speeds is one of the most effective ways of increasing the attractiveness of transit for urban travel. While surface transit in particular suffers from low speed, the desirabil­ity of higher speeds is not limited to it. Rapid transit has adequate speed for short to medium-distance trips in urban areas. However, for longer trips, particularly when there is a competing freeway facility, the requirement for speed is rather high. Since many station spacings are adopted on the basis of area coverage, high operating speed of the trains often cannot be achieved. Thus, typical lines of urban rapid ...


A Study Of The Dickey-Lincoln Hydroelectric Project And Its Impact On The Resources Of The Upper Saint John River Valley, Rosemary M. Manning, Sierra Club, New England Chapter Jan 1973

A Study Of The Dickey-Lincoln Hydroelectric Project And Its Impact On The Resources Of The Upper Saint John River Valley, Rosemary M. Manning, Sierra Club, New England Chapter

Dickey-Lincoln School Lakes Project

This report was under-taken primarily to evaluate the impact that the construction of the Dickey-Lincoln project would have upon the resources of the Upper St. John River, and to examine the assertion that the Dickey-Lincoln project constitutes a wise use of the public's environmental and economic resources. Since the case that has been made for the construction of the Dickey-Lincoln project rest primarily on the justification of the project in economic terms, this aspect of the project proposal will be intensively explored.

The Single Commodity Bulk Delivery Problem, Timothy S. Gemmel Jan 1973

The Single Commodity Bulk Delivery Problem, Timothy S. Gemmel

Theses and Dissertations

Recognition is given to a special class of delivery problem in which a particular product is supplied on a continuing basis to a specified set of customers by trucks which originate from a sentral terminal. The delivery locations have storage tanks with fixed capacities which the supplier is responsible for keeping adequately stocked at all times. An important attribute of this problem is that the users exhibit relatively stable demand patterns for the product.

An Evaluation Of Titanium Carbide Coated Tungsten Carbide Tools, John U. E. Shroyer Jan 1973

An Evaluation Of Titanium Carbide Coated Tungsten Carbide Tools, John U. E. Shroyer

Theses and Dissertations

In this experiment each tool produced by a particular manufacturer was tested at a set of roughing and finishing machining conditions for a turning operation of 4340 heat treated steel to determine if any significant differences in performance existed between the roughing and finishing grades in their respective recommended areas of application. It was concluded that there was very little significant difference in performance between the two TiC coated grades over the set of roughing and finishing conditions; and consequently, there is no need for two steel cutting TiC coated grades.

A Thermal Analysis Of A Cryogenic Expander With A Reciprocating Dispacer/Piston Incorporating An Annular Regenerator On The Displacer/Piston Outside Diameter, John Vincent Galdieri Jr. Jan 1973

A Thermal Analysis Of A Cryogenic Expander With A Reciprocating Dispacer/Piston Incorporating An Annular Regenerator On The Displacer/Piston Outside Diameter, John Vincent Galdieri Jr.

Theses and Dissertations

A cryogenic refrigerator using an expander with a reciprocating displacer or piston which has a thermal gradient from one end to the other suffers a loss of refrigeration due to heat transfer between the displacer/piston and the cylinder (shuttle heat transfer). This loss can be eliminated by designing an annular thermal regenerator on the outside diameter of the displacer/piston in such a manner as to match the temperature profile of the displacer/piston and the cylinder wall throughout the cycle.


Trends In Milking Systems, G W. Scott Jan 1973

Trends In Milking Systems, G W. Scott

Journal of the Department of Agriculture, Western Australia, Series 4

Twice daily milking is an essential task for the dairy farmer and the speed of milking influences the time available to him for other work and to the cows for extra grazing.

Modern milking systems can greatly contribute to these requirements by allowing the owner-farmer to handle a greater number of cows unaided, or in other situations to release labour from the shed for other work.

The following review leads from the better known basic sheds to the most modern types.
