Abstract (sommario):

The paper discusses the ceremony of the Loving Cup that follows the dinners of many City of London livery companies. It concludes that, far from being of Saxon origin, as has been widely believed, it was a Romantic revival of the late eighteenth century derived, almost certainly, from the medieval use of grace cups.

Abstract (sommario):

[abstFig src='/00280002/10.jpg' width=""300"" text='Claws attached to suction cups' ]Efficient economical test methods are widely needed worldwide. One target of this is to develop climbing robots that check for defects in concrete. These concrete-wall-climbing robots generally use suction cups to support themselves and test apparatus, but the danger exists of this expensive equipment falling. This may occur due to one of two reasons. The first is inadequate ring-seal decompression in suction cups and the second is suction cup slippage. We have added claws to suction cups to help prevent slippage. The claws we developed are attached to the suction cups to help grip the wall. In the sections below, we discuss the scratch tests we performed to test claw effectiveness in improving suction cup grip. We then prove through tests under actual conditions that the estimated grip force matched that of an actual suction cup's grip force with the claw.

Abstract (sommario):

Abstract In the selection of oviposition sites female mosquitoes use various cues to assess site quality to optimize survival of progeny. The presence of conspecific larvae influences this process. Interactive effects of oviposition site selection were studied in the malaria mosquito Anopheles coluzzii Coetzee & Wilkerson in dual- and no-choice assays, by exposing single gravid mosquitoes to oviposition cups containing 1) larvae of different developmental stages, 2) larvae-conditioned water (LCW), and 3) cups where visual cues of conspecific larvae were absent. Early-stage conspecific larvae had a positive effect on the oviposition response. By contrast, late stages of conspecific larvae had a negative effect. Oviposition choice was dependent on larval density. Moreover, in oviposition cups where larvae were hidden from view, late-stage larvae had a significant negative effect on oviposition suggesting the involvement of olfactory cues. LCW had no effect on oviposition response, indicating involvement of chemicals produced by larvae in vivo. It is concluded that the presence of larvae in a breeding site affects the oviposition response depending on the development stage of the larvae. These responses appear to be mediated by olfactory cues emitted by the larval habitat containing live larvae, resulting in the enhanced reproductive fitness of the females.

Abstract (sommario):

Since the 1960s, following the dramatic changes in the Roman Catholic Church, the design of the chalices used at the communion service became simplified; many of them becoming so plain that they are only wine goblets devoid of any decoration. As Catholics implement the changes of the Second Vatican Council, we have a growing desire for sacred vessels that better reflect a sense of awe.The purpose of this creative project is to explore symbolism used in chalice design. Traditional and newer symbols are incorporated into the chalices produced in this project.My creative process involves a community of people. Teachers, fellow students, friends and members of my church shared their knowledge, ideas and insights to enrich the final products.The sense of the sacred is not limited to God because God is present within each person. To be aware of the sacred in my own designs I need to be in touch with the sacred within me.

Abstract (sommario):

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2013.
Cataloged from PDF version of thesis.
Includes bibliographical references (pages 39-40).
Leaking in water pipe is a critical issue in Middle Eastern countries such as Kuwait where water is scarce. In-pipe robots can be dispatched to discover the network and inspect the inner surface of the pipe. This thesis describes the design and characterization of suction pads for in-pipe robots. The suction cups are made of hyperelastic materials that contain air channels inside. Instead of using conventional suction technique that is prone to leaking and loosing adhesion force, the suction cup is actuated by compressed air or liquid, which deforms the geometry of the cup to achieve suction. In order to verify the geometry changes during actuation, a uniaxial tension test was done on the elastic material used to acquire the material properties and the suction cup designs were then simulated using FEA in ABAQUS. Next, prototypes were designed in SolidWorks and fabricated using soft lithography techniques. To measure the suction force, pressure measurements were taken both inside the prototype channels and underneath the suction cup. Results show that a Positive Pressure Actuated Suction-cup (PPAS) of diameter forty millimeters can achieve suction force up to 68 N. As more air is inserted into PPAS, the suction force also increases. The concept has proved to be a feasible solution for pipe inspection robot.

Nous donnons leur déploiement versel, ainsi qu'une description complète du diagramme de bifurcation (par rapport à l'équivalence topologique) du déploiement versel propose. Pour atteindre ce but, nous utilisons la notion de systèmes étendus complets de Chebychev (ECT-systèmes). Nous introduisons une relation d'équivalence (équivalence caractéristique) pour des familles engendrées par des ECT-systèmes et montrons l'universalité du diagramme de bifurcation (par rapport à l'équivalence caractéristique) pour des familles linéaires d'ECT-systèmes. Nous montrons ensuite la trivialité du diagramme de bifurcation pour les déformations d'une famille linéaire d'ECT-systèmes. Nous généralisons ce résultat à une famille d'applications déplacement d'une déformation d'un champ Hamiltonien ayant un lacet homoclinique. Certains résultats semblables ont été obtenus récemment et indépendamment par P. Joyal.

Testo completo

Abstract (sommario):

Around the late third millennium BC small cup-shaped vessels began to appear in burial contexts across the North of England where they were found to be associated with Early Bronze Age funerary practices. Known by the name of incense cups, accessory vessels or miniature cups, their true purpose has been elusive. This study comprises an investigation of cups from Northern England and finds the tradition to be heavily influenced by Beaker culture practices resulting in the earliest cups emulating some attributes of Beaker ceramics. The Northern English Cup assemblage defies the current perception that all Cups are perforated as 63% are not; fabrics are found to be locally sourced and not imported and a review of the typology finds a strong regional adherence to the Food Vessel and Collared Urn tradition. Association in the grave with larger Urns is not as common as once believed and Cups have been found as the solitary ceramic indicating that they were important in their own right. Firing damage such as spalling has been interpreted as use of the funeral pyre for firing vessels prior to deposition with cremated remains and it is suggested that this is a recognisable signature of the cup tradition and therefore the name ‘funerary Cup’ is more appropriate. An active cross country trade network can be inferred from distributions of metalwork, precious materials and an affinity in some cases to Irish cups.

Abstract (sommario):

In a gas turbine engine combustor, combustion performance is tied to the spatial distribution of the fuel injected into the dome. Swirl cup, as an air blast atomizer, is widely used to provide a uniform presentation of fuel droplets to the combustor dome. In this paper, two swirl cups with different venturi angle have been studied: case 1 (with narrow venturi angle) and case 2 (with wide venturi angle). Kerosene is injected to the test domain through a simplex nozzle. The spatial distribution of droplet characteristics produced by the two swirl cups were measured using dual-phase Doppler anemometry (PDA). A single cup combustor has been built in order to characterize the swirl cups’ ignition phenomena. Spark ignition test has been performed for ground condition, two swirl cups’ lean ignition limits are obtained, and ignition sequences have been recorded by a high-speed video camera. Comparing the two swirl cups’ small droplets velocity, case 1 swirl cup produces a different velocity profile from typical swirl cup. The air stream outflowing from case 1 swirl cup just ran into the side wall. The droplet size around the spark plug of case 2 is smaller than case 1. Ignition test results show that case 2 swirl cup’s lean ignition limit is wider than case 1’s. Record of the ignition process deepened the understanding of spark ignition of the swirl diffusion flame. It takes some time for the kernel to anchor in swirl cup. The results demonstrate that swirl cup’s venturi shape strongly influence the spray structure. Thereby affect the combustor ignition performance.

Abstract (sommario):

Hyper compressors are designed for LDPE production, compressing ethylene up to 3500bar with only two stages of compression, in order to reach conditions for the polymerization. The high operating and fluctuating pressure strongly impact design and life of all cylinder components. The packing cups are among the most stressed components of a hyper compressor cylinder. They are particularly subjected to very high pulsating pressures, thus fatigue and wear. Therefore, they are periodically replaced during maintenance and are critical for availability of the hyper compressor. A typical hyper compressor packing assembly contains 5 to 6 disc shaped packing cups that contain the plunger sealing rings at the internal diameter. The packing cups are provided with lube oil ducts to lubricate the sealing elements. Typically these ducts extend axially through the assembly to the injection points. For that purpose each packing cup could have a different number of lube oil passages. Moreover, at the external diameter are located passages for packing cooling oil. For these reasons each of the packing cups is a unique part with different machining features. In order to optimize the availability of spare parts and standardize the product, a new design of hyper compressor packing cups has been evaluated, called further “all-purpose packing cup”. The idea was to make the packing cups all equal to each other, and potentially to reduce manufacturing and warehousing costs. This idea has been realized by introducing in a single all-purpose cup, multiple sectors angularly offset with each other. Each sector contains the oil ducts required for a given cup position in the assembly. By rotating the cup about the plunger axis by e.g. 90° or 180° the desired sector can be activated (put in fluid communication with adjacent lube oil ducts). In this way the “all-purpose packing cup” can be mounted in each of the 5 to 6 different positions in the packing assembly. The all-purpose cup design has been analyzed by a well validated FEA approach on the high cycle fatigue and flaw propagation safety margins. The analysis was performed considering all multiple possible load combinations where, depending on the assembly configuration, different active lube oil holes (holes that deliver oil to the plunger) were pressurized while all remaining ducts were left unpressurized.

Abstract (sommario):

Second stage cylinders for polyethylene hyper compressors are among the most stressed pressure vessels in the industry. Due to the high operating pressure and pressure fluctuations between suction and discharge, these cylinders must be designed to withstand high fatigue loads. Packing cups are the most critical cylinder component and, in particular, the lube oil ducts are the bottleneck for reliability. This work deals with a structural optimization of packing cups focused on the most critical packing cup area: the lube oil hole. Various pre-compression techniques (i.e., shrink-fit and autofrettage) are used to improve the fatigue behavior. Longer life and reliability are investigated with advanced design techniques such as finite element modeling and design of experiments. New design cups with a 50% higher fatigue safety factor have been obtained.

Abstract (sommario):

Cup anemometers are most commonly used for measuring wind speeds in the atmospheric boundary layer, among others for site assessment. The simple design of a cup anemometer consists of three cups mounted on a vertical shaft. Due to the difference in the drag coefficient of the open and the closed side of the cups the system is rotating, where the rotational frequency is proportional to the incoming wind speed. One downside of cup anemometers is their asymmetric dynamic response to accelerating and decelerating wind speeds under turbulent wind conditions. This asymmetry results in a systematic overestimation under turbulent wind conditions, the so-called over-speeding [3][4][5]. The goal of the presented experiments is to characterize the dynamical response of cup anemometers for decreasing wind velocities in particular. Additionally, the effect of different torques and an unbalanced system on the anemometer’s dynamics is investigated by adding rare earth magnets as weights to the cups. These characteristics are basis for the post processing of measured data under turbulent wind conditions. Regions of the measured time series that are dominated by the specific dynamics of the cup anemometer are therefore affected by over-speeding and should be excluded from further analysis. Systematic changes in the anemometer’s dynamics on the other hand, are indicators for damages e.g. wear of bearings or contamination of the cups [6].

Abstract (sommario):

More than one million hip joint replacements are performed each year in the world. However, the implants do not last forever due to material limitations, even though the operation is successful. The most common material combination used today is a CoCr head articulating against an UHMWPE (Ultra High Molecular Weight Polyethylene) acetabular cup. Several investigations have shown that the metal head is roughened inside the body and thus accelerating wear of the polymer cup. The sterilization method is also known to have effect on the wear properties. In vitro wear tests are however usually performed with as new implants. This investigation aimed at study the impact of head surface roughness on wear of both sterilized and non-sterilized acetabular cups. A total of nine acetabular cup and head pairs were wear tested in a hip joint simulator for 2Million cycles (Mc) with bovine calf serum as lubricant. Wear was determined by weighing of all cups. The heads were of CoCrMo and the average initial head surface roughness was 15nm (Ra), measured with a white light interference profilometer. The roughening was produced with a SiC paper producing circular multidirectional wear tracks to a surface roughness of about 400nm (Ra). The cups were of UHMWPE and the sterilized cups were 3Mrad gamma-radiated in nitrogen. The surface roughness after wear test was unchanged for the roughened heads, while the initially smooth heads were slightly roughened. Preliminary results show that the rough heads increase the wear of the cups 2-fold. The γ-irradiation affected both wear- and soak rate.

Abstract (sommario):

Swirl cups (hybrid atomizers) are being widely employed in aero gas turbine engine combustors for their established merits in terms of achieving satisfactory atomization over the entire combustor operating regime. Even though several investigators have worked on development of these swirl cups, there is a scanty data reported in literature relevant to their design. In the present study, flow behavior in a swirl cup assembled in a confined chamber similar to a gas turbine combustor has been analyzed. Flow analysis has been carried out using ANSYS Fluent and turbulence has been modeled using Realizable k-ϵ model. Six swirl cup configurations have been analyzed; mass flow ratio between primary and secondary swirler and venturi converging area ratio have been varied. The effect of these parameters on downstream flow field has been studied by analyzing the profiles of axial, tangential and radial velocities downstream of swirl cup. The size and shape of the recirculation zone has been analyzed and reported for all configurations. Also, the mass flow recirculated by swirl cup has been estimated and compared amongst the configurations analyzed. Data thus generated is very useful in designing such swirl cups of gas turbine combustors.

Abstract (sommario):

A three-dimensional contact-coupled wear model was developed and used to predict the long-term wear in both conventional and cross-linked ultra high molecular weight polyethylene (UHMWPE) cups, particular to examine the effect of the head diameter and the UHMWPE cup wall thickness. The wear factors were determined from the simulator testing of 28 mm diameter cups. The maximum contact pressure was found to decrease with the increase of head diameter up to 48 mm, corresponding to the decrease in the cup wall thickness for a fixed outside diameter of the cup. Volumetric wear rate was predicted to increase as the head size increased for the conventional UHMWPE, as well as the cross-linked UHMWPE, although at a much lower rate for the latter due to the smaller wear factor.
