The Evolution of Diesel Engines
GENERAL ARTICLE The Evolution of Diesel Engines U Shrinivasa Rudolf Diesel thought of an engine which is inherently more efficient than the steam engines of the end-nineteenth century, for providing motive power in a distributed way. His intense perseverance, spread over a decade, led to the engines of today which bear his name. U Shrinivasa teaches Steam Engines: History vibrations and dynamics of machinery at the Department The origin of diesel engines is intimately related to the history of of Mechanical Engineering, steam engines. The Greeks and the Romans knew that steam IISc. His other interests include the use of straight could somehow be harnessed to do useful work. The device vegetable oils in diesel aeolipile (Figure 1) known to Hero of Alexandria was a primitive engines for sustainable reaction turbine apparently used to open temple doors! However development and working this aspect of obtaining power from steam was soon forgotten and with CAE applications in the industries. millennia later when there was a requirement for lifting water from coal mines, steam was introduced into a large vessel and quenched to create a low pressure for sucking the water to be pumped. Newcomen in 1710 introduced a cylinder piston ar- rangement and a hinged beam (Figure 2) such that water could be pumped from greater depths. The condensing steam in the cylin- der pulled the piston down to create the pumping action. Another half a century later, in 1765, James Watt avoided the cooling of the hot chamber containing steam by adding a separate condensing chamber (Figure 3). This successful steam engine pump found investors to manufacture it but the coal mines already had horses to lift the water to be pumped. -
Connected Histories: the Dynamics of Bronze Age Interaction and Trade 1500–1100 BC
Proceedings of the Prehistoric Society 81, 2015, pp. 361–392 © The Prehistoric Society doi:10.1017/ppr.2015.17 Connected Histories: the Dynamics of Bronze Age Interaction and Trade 1500–1100 BC By KRISTIAN KRISTIANSEN1 and PAULINA SUCHOWSKA-DUCKE2 The Bronze Age was the first epoch in which societies became irreversibly linked in their co-dependence on ores and metallurgical skills that were unevenly distributed in geographical space. Access to these critical resources was secured not only via long-distance physical trade routes, making use of landscape features such as river networks, as well as built roads, but also by creating immaterial social networks, consisting of interpersonal relations and diplomatic alliances, established and maintained through the exchange of extraordinary objects (gifts). In this article, we reason about Bronze Age communication networks and apply the results of use-wear analysis to create robust indicators of the rise and fall of political and commercial networks. In conclusion, we discuss some of the historical forces behind the phenomena and processes observable in the archaeological record of the Bronze Age in Europe and beyond.

The buried remains of these archaeological settlements are characterized by the presence of a system of palaeo-environments and a consequent natural gradient in soil moisture content. These differences in the soil are often firstly detectable on the surface during the seasonal variations, with aerial, satellite, and Laser Imaging Detection and Ranging (LIDAR) images, without any information on the lateral and in-depth extension of the related buried structures. The variation in the moisture content of soils is directly related to their differences in electrical conductivity. Electrical resistivity tomography (ERT) and frequency domain electromagnetic (FDEM), also known as electromagnetic induction (EMI) measurements, provide non-direct measurements of electrical conductivity in the soils, helping in the reconstruction of the geometry of different buried structures. -
Water, Air and Fire at Work in Hero's Machines
Water, air and fire at work in Hero’s machines Amelia Carolina Sparavigna Dipartimento di Fisica, Politecnico di Torino Corso Duca degli Abruzzi 24, Torino, Italy Known as the Michanikos, Hero of Alexandria is considered the inventor of the world's first steam engine and of many other sophisticated devices. Here we discuss three of them as described in his book “Pneumatica”. These machines, working with water, air and fire, are clear examples of the deep knowledge of fluid dynamics reached by the Hellenistic scientists. Hero of Alexandria, known as the Mechanicos, lived during the first century in the Roman Egypt [1]. He was probably a Greek mathematician and engineer who resided in the city of Alexandria. We know his work from some of writings and designs that have been arrived nowadays in their Greek original or in Arabic translations. From his own writings, it is possible to gather that he knew the works of Archimedes and of Philo the Byzantian, who was a contemporary of Ctesibius [2]. It is almost certain that Heron taught at the Museum, a college for combined philosophy and literary studies and a religious place of cult of Muses, that included the famous Library. For this reason, Hero claimed himself a pupil of Ctesibius, who was probably the first head of the Museum of Alexandria. Most of Hero’s writings appear as lecture notes for courses in mathematics, mechanics, physics and pneumatics [2]. In optics, Hero formulated the Principle of the Shortest Path of Light, principle telling that if a ray of light propagates from a point to another one within the same medium, the followed path is the shortest possible. -
Hero's Engine Build Instructions
OMAHA MAKER GROUP Explore Technology, Science, & Art 8410 K Street, #5 – Omaha, NE 68127 [email protected] www.omahamakergroup.org How to Make a Hero’s Steam Engine Description: An easy steam engine (Hero's engine) is constructed from a soda can, some thread, and a heat source. Burning fuel heats the engine to produce steam. The chemical energy in the fuel is converted to a rotation of the can, illustrating the conversion of chemical energy to thermal energy to mechanical energy. Materials: Unopened soda can, thread, a small nail or pin, thread, something to hang the can over the fuel, candle or “Sterno” fuel, lighter, gloves Step 1 Do this outside or over a sink. Use a pin or small nail to make a hole in the side of a soda can. The can must still be unopened. When you pull the pin out there will likely be some spray. Step 2 Empty the can through the pinhole. Depending on the soda in the can, shaking it will increase the pressure in the can causing the soda to come out faster. Don't worry if there's a little soda left when you're done. Step 3 Make another hole in the other side of the can. Step 4 Put the pin back in one of the holes and pull it down as shown in the photos below. This modifies the hole enough for the steam to later come out at an angle with respect to the can. Step 5 Do the same for the other hole, pulling the pin in the same direction with respect to the can. -
Friuli Between Late Copper Age and Early Bronze Age
Traces in Time n. 5 – 2015 ISSN 2038-7709 FRIULI BETWEEN LATE COPPER AGE AND EARLY BRONZE AGE AUTHOR Giulio Simeoni CATEGORY Conference Procedeengs - Bronze Age Italian Meeting (BAIM) 2012, November 16th-17th, Parma (Italy) LANGUAGE English - Translation: Marina Baralle. _______________________________________________________________ INTRODUCTION The period commonly referred as Eneolithic or Copper Age is currently poorly documented in Friuli (Borgna et al. 2011). In particular, features that can be clearly related to the Bell Beaker culture appear to be entirely absent. Until recently, this long sequence of time was basically considered a transition between the Neolithic and a period of the Bronze Age that has been somewhat better documented, but in many ways still needs to be clearly defined. The discovery of the remains of two dwellings and the re-analysis of ceramic and metal artefacts belonging to the last centuries of the third millennium BC has recently suggested a cultural framework for the north-eastern tip of the Italian territory that, in general, agrees with what has already been observed for the Eneolithic period and is in accordance with the trends of the following Early Bronze Age period. LATE COPPER AGE The aforementioned residential structures date to the end of Eneolithic period and consist of the remains of two huts discovered at S. Odorico of Flaibano (Udine) between 2007 and 2008 (Balasso et al. 2009). The diagnostic fragments come from the stratigraphic units of the most recent hut and consist of a body fragment belonging to a bowl with inverted body walls and tubular handles attached to the rim and a small rim fragment belonging to a bowl with a flattened lip bevelled towards the interior, with a slight exterior groove (Fig. -

The Contribution of the Segovia Mint Factory to the History of Manufacturing As an Example of Mass Production in the 16Th Century
applied sciences Article The Contribution of the Segovia Mint Factory to the History of Manufacturing as an Example of Mass Production in the 16th Century Francisco García-Ahumada * and Cristina Gonzalez-Gaya * Department of Construction and Manufacturing Engineering, ETSII-Universidad Nacional de Educación a Distancia (UNED), C/Juan del Rosal 12, 28040 Madrid, Spain * Correspondence: [email protected] (F.G.-A.); [email protected] (C.G.-G.); Tel.: +34-629-67-27-37 (C.G.-G.) Received: 1 October 2019; Accepted: 26 November 2019; Published: 7 December 2019 Abstract: A new means of minting currency was first used at the Hall Mint in Tyrol in 1567. This new minting process employed a roller instead of a hammer and used hydropower to fuel the laminating and coining mills, as well as ancillary equipment, such as the forge or the lathe. In 1577, Philip II of Spain expressed his interest in the new technology and, after a successful technology transfer negotiation with the County of Tyrol, Juan de Herrera was commissioned to design a factory to accommodate this new minting process. The resulting design seamlessly integrated this new technology. The architectural layout of the factory was derived from the integration of different trades related to the manufacturing workflow, and their effective distribution within a more effective workplace allowed for better use of the hydraulic resources available, and, thus, improvements in the productivity and reliability of the manufacturing process, as well as in the quality of the finished product. Juan de Herrera’s design led to the creation of a ground-breaking manufacturing process, unparalleled in the mint industry in Europe at the time. -
Ancient Technology Honors Seminar III, Inhabiting Other Lives, FIU Honors College (IDH 2003-U01) Fall Semester – 2018
Ancient Technology Honors Seminar III, Inhabiting Other Lives, FIU Honors College (IDH 2003-U01) Fall Semester – 2018 Instructor: Dr. Jill Baker Tuesdays and Thursdays, 11.00 a.m. to 12.15 p.m. Office location: DM 233, (305) 348-4100 Classroom: GC 286 Office hours: By Appointment or Borders Café GC, 10.15-10.45 a.m. Tu/Th email: [email protected] Purpose of the Course: The purpose of this class is to explore ancient technology and engineering. Thanks to archaeological excavation, monumental buildings, gates, city walls, roads, and ships have been discovered. These sometimes-gigantic structures were constructed without the benefit of bull dozers, cranes, lifts, drills, or any of the modern tools with which we are familiar and lived in relative luxury. So, how did the ancient people move materials and build these amazing cities with surprising amenities? This class seeks to elucidate the ingenuity of the ancient mind in order to understand their technology which in turn will help us to better understand our own and apply these, and new, ideas to the future. Questions that will be addressed include what the ancients knew, when and how did they know it; what machines and tools did they use and for what purposes; how does technology and engineering help society advance; how can we apply these principles to our world and to the future? Fall Semester: The big stuff - monumental constructions, residential dwellings, urban planning, etc. Spring Semester: The smaller things – machines, maritime transportation, terrestrial transportation, medicine, time-keeping, etc. This syllabus will be distributed on the first day of class in the spring semester. -

ARCL 0141 Mediterranean Prehistory
INSTITUTE OF ARCHAEOLOGY ARCL 0141 Mediterranean Prehistory 2019-20, Term 1 - 15 CREDITS Deadlines for coursework: 11th November 2019, 13th January 2020 Coordinator: Dr. Borja Legarra Herrero [email protected] Office 106, tel. (0) 20 7679 1539 Please see the last page of this document for important information about submission and marking procedures, or links to the relevant webpages 1 OVERVIEW Introduction This course reunites the study and analysis of prehistoric societies around the Mediterranean basin into a coherent if diverse exploration. It takes a long-term perspective, ranging from the first modern human occupation in the region to the start of the 1st millennium BCE, and a broad spatial approach, searching for the overall trends and conditions that underlie local phenomena. Opening topics include the glacial Mediterranean and origins of seafaring, early Holocene Levantine-European farming, and Chalcolithic societies. The main body of the course is formed by the multiple transformations of the late 4th, 3rd and 2nd millennium BC, including the environmental ‘mediterraneanisation’ of the basin, the rise of the first complex societies in east and west Mediterranean and the formation of world-system relations at the east Mediterranean. A final session examines the transition to the Iron Age in the context of the emergence of pan-Mediterranean networks, and this also acts as a link to G202. This course is designed to interlock with G206, which explores Mediterranean dynamics from a diachronic and comparative perspective. Equally, it can be taken in conjunction with courses in the prehistory of specific regions, such as the Aegean, Italy, the Levant, Anatolia and Egypt, as well as Europe and Africa. -

The Egyptian civilization is thought to have been begun in about 3150 BC until 31 BC. For the ancient Greek civilization, it started in the period of Minoan (ca. 3200 BC) up to the ending of the Hellenistic era. There are various parallels and dissimilarities between both civilizations. They co-existed during a certain timeframe (from ca. 2000 to ca. 146 BC); however, they were in two different geographic areas. Both civilizations were massive traders, subsequently, they deeply influenced the regional civilizations which have developed in that region. Various scientific and technological principles were established by both civilizations through their long histories. Water management was one of these major technologies. Accordingly, they have significantly influenced the ancient world’s hydro-technologies.
