Subjects for Students‘ Theses Amount and complexity of the Project/Bachelor/Master Thesis subject will be adjusted to the kind of student‘s thesis! Subject: Trolley Conveyors – Steel Wheel or Roller Guided Systems Trolley Conveyors are established as a niche product in public transport, especially in Germany and Japan. The most well known system is probably the Wuppertal Suspension Monorail. Here the guidance is realized by using a steel wheel with two flanges rolling over a steel rail. Also the weight support as well as the drive/brake function are realized that way. Systems like the H-Bahn in Dortmund and Düsseldorf use separate support and guiding wheels with solid By Oktaeder - German Wiki de:Bild:Schwebebahn ueber Strasse.jpg by Oktaeder, public domain,(exerpt) rubber or pneumatic tires. https://commons.wikimedia.org/w/index.php?curid=34148 Roller guided systems have either the disadvantage of a digital guiding function, when the running gear is only guided when touching one vertical guide rail because of the gauge clearance or they have a high abrasive wear of the wheels when these are fixed on both sides to the running edges of the rail. A further disadvantage of the roller guided system is the „bumpy“ track which allows only low speeds and moderate vibration comfort. The suspension monorail however has an operating speed of 60 km/h and good comfort features. A possible disadvantage for the steel wheel/rail system might be the noise. The task is to make a detailed study on the technology of the running gears of H- CC BY-SA 3.0, https://commons.wikimedia.org/ Bahn and the suspension railway and compare them with each other.

Sveučilište u Zagrebu Fakultet prometnih znanosti ZAVRŠNI RAD ANALIZA TEHNIČKO – EKSPLOATACIJSKIH ZNAČAJKI TRAMVAJA ANALYSIS OF TECHNICAL AND EXPLOITATION FEAUTERS OF TRAMS Mentor: doc. dr. sc. Željko Šarić Student: Maja Ćuk JMBAG: 0135210885 Zagreb, svibanj 2018. SAŽETAK U ovom završnom radu analizirale su se tehničko-eksploatacijske značajke tramvaja. Također, navedeni su i različiti svijetski primjeri prijevoza putnika u javnom gradskom prometu kao što su autobusni prijevoz, trolejbusni, tramvajski, metro, uspinjača, taksi.... Razlike među navedenim sustavima su velike, a najviše se očituju u prijevoznoj sposobnosti, brzini te količini financijskih ulaganja koja su potrebna za njihovo uvođenje. Funkcioniranje prometa ovisi i o strukturi i veličini grada. Javni gradski prijevoz u Zagrebu uključuje podsustave za čije je funkcioniranje uglavnom odgovoran Zagrebački električni tramvaj (ZET). Svaki od podsustava javnog prijevoza u gradu Zagrebu ima svoja obilježja i način na koji pruža uslugu prijevoza građanima. Najveći podsustav u Zagrebu je tramvajski sustav. Cilj analize ovog tramvajskog sustava je pružiti sigurnost, udobnost i točnost kako bi svi tramvajski putnici stigli na svoja planirana odredišta u planirano vrijeme te kako bi korisnici javnog prijevoza bili zadovoljni uslugom vožnje. Kako bi se poboljšao sustav javnog prijevoza u Zagrebu i u budućnosti, bitno je redovito nastaviti pratiti i analizirati prometne i tehničke karakteristike tramvajskog sustava u gradu Zagrebu. KLJUČNE RIJEČI: tehničko-eksplotacijske značajke tramvaja, javni gradski prijevoz u Zagrebu, podsustavi javnog prijevoza SUMMARY In this final thesis were analysed technical-exploitation features of trams. Also, in this final thesis are mentioned different world-wide examples od city public transportation systems like bus transport, trolley-bus, water-bus, tram, metro, funiculars, taxis..

Wingler June 2019 1 From the 1902 Mono-Rail guided Bullock Cart in India to the 21th Century Mono-Rail guided Los Angeles Airport Automatic People Mover (LAX APM) in USA I. Mono-Rail guided Carriage Transport in India from 1902 to 1927 The first Mono-Rail guided goods carriage system, a road borne railway system, had been the Kundala Valley Railway in India, which was built in 1902 and operated between Munnar and Top Station in the Kannan Devan Hills of Kerala. It operated with a cart- vehicle, built to transport tea and other goods. The initial cart road was cut in 1902 and then replaced by the monorail goods carriage system along the road leading from Munnar to Top Station for the purpose of transporting tea and other products from Munnar and Madupatty to Top Station. This monorail was based on the Ewing System (see below) and had small steel-wheels placed on the mono-rail track while a larger wheel rested on the road to balance the monorail. The mono-rail was pulled by bullocks. Top Station was a trans-shipment point for delivery of tea from Munnar to Bodinayakkanur. Tea chests arriving at Top Station were then transported by an aerial ropeway from Top Station 5 km (3 mi) down-hill to the south to Kottagudi, Tamil Nadu, which popularly became known as "Bottom Station".

GUIDEWAY DESIGN AND FABRICATION METHOD FOR THE SPARTAN SUPERWAY A MS Project Presented to The Faculty of the Department of Mechanical Engineering San José State University In Partial Fulfillment of the Requirements for the Degree Master of Science By Liwei Lu 12th Dec 2020 GUIDEWAY DESIGN AND FABRICATION METHOD FOR THE SPARTAN SUPERWAY By Liwei Lu APPROVED BY THE DEPARTMENT OF MECHANICAL ENGINEERING SAN JOSÉ STATE UNIVERSITY Dec 2020 ----------------------------------------------------------------------------- Burford Furman, Ph.D. (Chair) ----------------------------------------------------------------------------- Ron Swenson, International Institute of Sustainable Transportation ----------------------------------------------------------------------------- James Mokri, Lecturer of ME Department, SJSU ABSTRACT The preliminary design for the guideway elements was undertaken throughout the semester. Straight guideway beam, curved guideway beam, supporting structure, and heat expansion joint has been modeled and analyzed. The current design for the guideway for SPARTAN Superway project followed the concept of SAFEGE (Société Anonyme Française d' Etude de Gestion et d' Entreprises, named after a French Company) type guideway. It’s a rectangular hollow steel beam with an open bottom, and outside of the hollow steel beams there are ribs that can hold the shape of the guideway from collapsing. Finite element analysis (FEA) method is the main approach when designing the guideway. After the FEA design study, a 0.1-inch wall thickness and 48 inches rib spacing has been determined, which will give the guideway the best performance. FEA study shows that all the guideways and support structures designed have a factor of safety 5.0 or above, and the maximum deflection of all the guideways and supporting structures are fulfilling the L/800 spec. It can also handle a magnitude 6.9 earthquake and a 115mph wind load.

Adverse Effects of Noise on Child Development Anna Makles Kerstin Schneider CESIFO WORKING PAPER NO. 6281 CATEGORY 5: ECONOMICS OF EDUCATION DECEMBER 2016 An electronic version of the paper may be downloaded • from the SSRN website: www.SSRN.com • from the RePEc website: www.RePEc.org • from the CESifo website: www.CESifoT -group.org/wpT ISSN 2364-1428 CESifo Working Paper No. 6281 Quiet Please! Adverse Effects of Noise on Child Development Abstract Noise pollution is detrimental to health and to cognitive development of children. This is not only true for extreme levels of noise in the neighborhood of an airport but also to traffic noise in urban areas. Using a census of preschool children, we show that children who are exposed to intensive traffic noise significantly fall behind in terms of school readiness. Being exposed to additional 10 dB(A) compares to about 3 months in kindergarten. We contribute to the literature and the policy debate by working with administrative data and focusing on everyday exposure to noise. The proposed method is easily applied to other regions. We assess the public costs of different abatement instruments and compare the costs to the benefits. It turns out that the commonly used abatement measures like quiet pavement or noise protection walls in densely populated areas of about 3,000 to 5,000 inhabitants per km2 can be cost efficient, even with a conservative assessment of the benefits. JEL-Codes: I180, I260, Q530, H230, H540. Keywords: noise, child development, early education, abatement, abatement costs.
