11	Transportation Study of Release from a Space Elevator to Cislunar Space / Transportstudie av frigöring från en rymdhiss till Cislunar-rymden Griffin, Daniel January 2023 (has links) To leave Earth’s gravity well and ascend into Cislunar space takes ingenuity, and the engineering feats of many. Now to propel humanity further into space, rockets will need assistance to provide the large requirements of mass to be used for space structures. Tsiolkovsky’s Rocket Equation greatly limits the advantages of rockets and leaves an opening for Space Elevators to assist in a dual space access approach. By moving a large amount of mass routinely, efficiently, environmentally friendly and with daily launches towards space. Along with the apex anchor situated at 100,000 km for emergency assistance across all Cislunar space, and to act as both storage facilities and a construction zone. Space Elevators are the railway to space and can supplement rockets by transforming how mass is transported to Cislunar space and beyond. / Att lämna jordens gravitationsbrunn och stiga upp i Cislunar-rymden kräver uppfinningsrikedom och mångas ingenjörsprestationer. För att nu driva mänskligheten längre ut i rymden kommer raketer att behöva hjälp för att tillhandahålla de stora kraven på massa som ska användas för rymdstrukturer. Tsiolkovskys raketekvation begränsar i hög grad fördelarna med raketer och lämnar en öppning för rymdhissar för att hjälpa till med en dubbel rymdtillgång. Rymdhissar kan att flytta en stor mängd massa rutinmässigt, effektivt, miljövänligt och med dagliga uppskjutningar mot rymden. Apex-ankaret som ligger på 100 000 km kan fungera för nödhjälp över hela Cislunar-utrymmet och som både lagringsutrymmen och en konstruktionszon. Rymdhissar är järnvägen till rymden och kan komplettera raketer genom transformation hur massa transporteras till Cislunar rymden och bortom.

12	Dopravní síť Pardubic, srovnání s Hradcem Králové / Traffic network of Pardubice, comparison with Hradec Králové Dvořáková, Iva January 2009 (has links) Description and evaluation of a traffic network of Pardubice in all transport sectors (air, water, railway, road and cycling) and its comparison with a network of Hradec Králové. Integration of both transport systems. Suggestions for improvement of traffic infrastructure and transport integration. Optimalization of connection of chosen urban neighbourhood with a town centre by urban mass transportation.
13	Vyhledávání spojů v jízdních řádech / Traffic Connection Searching in Transport Schedules Žižka, Ondřej January 2008 (has links) Everyday need of modern society is a mass personal transit on a regular basis. For this purpose, mass transit systems exist which obey aforethought schedule. This thesis' goal is to examine the means of automatic search of connections from one place to another, implement such search, and to advance the search algorithm using the soft-computing paradigms. Minor goal would be a research of SQL language procedural capabilities, which could support mass pseudo-parallel computations.
14	Riding Red Ink: Public Ownership of Mass Transit in Indianapolis Wilhite, Ryan Daniel January 2011 (has links) Note During the research process, IndyGo donated some of the resources cited within this paper to the Indiana Historical Society. That collection has not been archived yet. Further, IndyGo may have placed other documents (created during the time of public ownership) in the Indiana State Archives or the Indiana State Library. / Indiana University-Purdue University Indianapolis (IUPUI) / Today, most urban mass transit providers are publicly owned. Just a few decades ago, and for a majority of the history of mass transit, private owners provided transportation for communities. The decline of private ownership in Indianapolis resulted in transit crisis that pitted private owners against local government, riders and community groups. Advocates lambasted the private owners for their profit-first tactics, pointing to the dividends gained by the private owners. These owners, the Midland Transportation Corporation, also owned the mass transit companies in Milwaukee, Wisconsin and Louisville, Kentucky. Indianapolis politicians, residents and newspapers, all firmly conservative, hoped private owners could continue to operate Indianapolis Transit Systems without public assistance. The imminent failure prompted a discussion of the future of transportation in the city of Indianapolis. Community groups hoped the new public corporation would increase service for Indianapolis and not continue the skeleton system managed by the private owners. A storm of uncontrollable events prevented the robust expansion of the new public corporation and its lack of funding resulted in a continuing decline of service, much akin to the private owners that were abhorred by transit riders. Public ownership in Indianapolis revealed the importance of public ownership in the historiography of mass transportation and urban history. The regional investigation of Midland Transportation confirmed the notion of transit as a unique industry, both in its industrial relations and influence of the locality. The basic rationale for public ownership in Indianapolis would be the most important: the provision of public transportation for those unable to afford private transportation to obtain necessary services. public corporations transit dependent Indianapolis Transit Systems Indianapolis, IN mass transit mass transportation Midland Transportation Milwaukee & Suburban Transport Co.
