This thesis is deals with design of panoramatic glass elevator which is integrated into concet of contemporary architecture. Required purposes is bring in original view of submission to modern glass elevator. I want to use my fancy for something more then only designing shape. Initial point must be some idea, some logical concept. Desing and materials are result of this concept. Shape respect logical though. I want create some view point of interior. Dominant, which grip of beauty, fluent movement, used materials and curves defining own design. I want design interior jewel. Jewel, which respect space and together are complex. Object reflective philosophy and image of firm.

Design vysokozdvižného vozíku / Design of fork-lift truckVaňková, Jana January 2009 (has links)
This diploma thesis deals with design features of a customs swivel cabin fork-lift truck. Concept is adapted to the technical and ergonomic requirements and the main goal of this concept is to provide original design with a view to the future. The complex concept meets the operational, technical and ergonomic demands of such engines. The project is focused on the design concept and complex contour-composition of the swivel cabin fork-lift truck. Designed of the fork-lift truck stems from the modern technological methods and the construction is ready for production and everyday operating usage, hence the production of this project would be rather expensive for the local market. However, it might be possible to start the production of this fork-lift truck, equipped by various functional components, sometime in the future and such extra functional components will be included as basic accessories of any fork-lift truck.

Development and analysis of turbulence models for flows with strong curvature and rotationGrundestam, Olof January 2004 (has links)
An explicit algebraic Reynolds stress model (EARSM) based ona pressure strain rate model including terms tensoriallynonlinear in the mean velocity gradients is developed in orderto improve predictions for .ows with strong curvature and/orrotation. This work has been carried out in the context of acollaborative international project on high-lift aerodynamics.For 2D mean .ows the nonlinear terms can easily be accountedfor in the model formulation. This is not the case for 3D mean.ows and approximations making the 2D and 3D mean .owformulations consistent are suggested. The proposed EARSM, theparent-EARSM and the corresponding di.erential Reynolds stressmodels (DRSM) are tested for spanwise rotating channel .ow andaxially rotating pipe .ow. The model predictions are comparedto experimental and DNS data. The nonlinear extensions areshown to have a signi.cant e.ect on the .ow predictions,somewhat less pronounced for the DRSM though. The turbulentdi.usion modelling in the EARSM computations is important forthe rotating pipe. It is shown that by using a Daly and Harlowdi.usion model, turbulence levels in good agreement withexperiments and DRSM can be achieved. However, by using asimpler e.ective eddy viscosity based di.usion model theturbulence kinetic energy levels are drastically overpredicted.Finally the proposed EARSM is tested on a standard high-liftcon.guration. The EARSM predictions are compared withexperiments and the predictions made by the standard K - ωtwo-equation model. Descriptors:Turbulence model, nonlinear modelling,streamline curvature, high-lift aerodynamics.

Investigation of Aerodynamic HysteresisPeterson, Gerald Heber 01 September 1964 (has links)
The word hysteresis is derived from a Greek word meaning "to lag 'behind". As specifically applied to fluid flow around bodies with transient angles of attack in and near the stall region, "aerodynamic hysteresis" is used to describe the effect of delay in boundary layer separation and reattachment upon the lift, drag and pitching moment. Experimental work done on airfoils by H. Studer showed that for increasing angles of attack flow "separation is delayed to an angle of attack appreciably greater than that for a stationary airfoil. On the return movement, re-establishment of a smooth flow is also delayed." [1]* The result is that under transient conditions "more than one value of flow coefficient (and thus lift, drag and pitching moment) can be obtained for a single angle of attack. . ., depending upon the direction in which the particular angle of attack is approached." [2]

Domination Edge Lift Critical TreesDesormeaux, Wyatt J., Haynes, Teresa W., Henning, Michael A. 01 March 2012 (has links)
Let uxv be an induced path with center x in a graph G. The edge lifting of uv off x is defined as the action of removing edges ux and vx from the edge set of G, while adding the edge uv to the edge set of G. We study trees for which every possible edge lift changes the domination number. We show that there are no trees for which every possible edge lift decreases the domination number. Trees for which every possible edge lift increases the domination number are characterized.

The Development and Fabrication of a Modular Vertical Reciprocating Conveyor System for the Transportation of Materials To and From a Mezzanine.Crum, Matthew Paul 17 December 2011 (has links) (PDF)
The purpose of this developmental project was to design and fabricate a vertical reciprocating conveyor in order to eliminate the process of manually carrying 27 pound containers of plastic resin up and down a flight of offset space saver stairs. This project took place and was built for Phoenix Closures Incorporated. The conveyor was designed and built in house because there are no commercially available vertical reciprocating conveyors available that meet the necessary requirements.
The capabilities of the proposed vertical reciprocating conveyor are not limited to the carrying of the containers but designed to carry vacuum cleaners, tool boxes, and spare parts to the mezzanine. The vertical reciprocating conveyor is designed for a greater capacity then the 27 pounds the container of plastic resin weighs, but the safety systems are not designed in a way that would allow the conveyor to lift a greater amount of weight.

A Lift of Cohomology Eigenclasses of Hecke OperatorsHansen, Brian Francis 24 May 2010 (has links) (PDF)
A considerable amount of evidence has shown that for every prime p &neq; N observed, a simultaneous eigenvector v_0 of Hecke operators T(l,i), i=1,2, in H^3(Γ_0(N),F(0,0,0)) has a “lift” v in H^3(Γ_0(N),F(p−1,0,0)) — i.e., a simultaneous eigenvector v of Hecke operators having the same system of eigenvalues that v_0 has. For each prime p>3 and N=11 and 17, we construct a vector v that is in the cohomology group H^3(Γ_0(N),F(p−1,0,0)). This is the first construction of an element of infinitely many different cohomology groups, other than modulo p reductions of characteristic zero objects. We proceed to show that v is an eigenvector of the Hecke operators T(2,1) and T(2,2) for p>3. Furthermore, we demonstrate that in many cases, v is a simultaneous eigenvector of all the Hecke operators.

Comparison Between the Trap Bar Dead Lift and Back Squat Exercises on Vertical JumpYoung, Douglas A. 13 July 2011 (has links) (PDF)
The ability to produce power during competition is essential. Football requires explosive power in order to get off the ball faster, increase speed of the first step, and increase the height of the vertical jump. Most strength training professionals use the back squat to increase power of the lower extremities; however, as large forces are placed on the back, athletes are at greater risk for injury. The trap bar dead lift is similar to the back squat in movement and form, but the trap bar dead lift reduces the force on the lower back. After testing for maximum vertical jump,athletes at Timpview High School participated in a strength program using either back squats or trap bar dead lift for seven weeks. A pre-test, mid-test and post-test were performed to calculate the increase in maximum vertical jump, if any. It was found that neither lift was significantly different than the other when testing for maximum vertical jump. These results will allow strength training professionals to use the trap bar dead lift instead of the back squats in subjects similar to those participating in the study.
