Abstract:
Abstract In this paper we have studied influence of attenuation on conversion processes of the fundamental mode (FM) in multihelicoidal optical fibers (MHF) in the vicinity of the point of accidental spectrum degeneracy within the framework of the scalar approximation. To this end, we have obtained expressions for modes of the MHF, which consist of the FM and an optical vortex (OV), and shown that conversion of the FM into the OV takes place. The difference in the attenuation coefficients for the partial fields of MHF’s modes leads to deterioration in the conversion process even with an ideal

Abstract:
Abstract Over Arctic sea ice, pressure ridges and floe and melt pond edges all introduce discrete obstructions to the flow of air or water past the ice and are a source of form drag. In current climate models form drag is only accounted for by tuning the air–ice and ice–ocean drag coefficients, that is, by effectively altering the roughness length in a surface drag parameterization. The existing approach of the skin drag parameter tuning is poorly constrained by observations and fails to describe correctly the physics associated with the air–ice and ocean–ice drag.

Different factors were shown to alter the vibration characteristics of soft-tissue compartments during running. Changing pre-heel strike muscle activation or changing footwear conditions represents two possibilities to influence the vibration response via frequency shift or altered damping. Associated with the study of muscle pre-tuning is the difficulty in quantifying clean experimental data for the acceleration of soft-tissue compartments and muscle activities in heterogeneous populations.

The prediction of the heat transfer coefficient commonly relies on the development of new empirical prediction equations when operating conditions and refrigerants change from the existing equations. Creating new prediction equations is expensive and time-consuming; therefore, recent attention has been given to machine learning approaches. However, machine learning requires a large amount of data, and insufficient data can result in inadequate accuracy and applicability.

I describe the musical aesthetic of the Second Viennese School as conditioned by and born out of equal temperament. In contrast, tonal music often employs intonation that varies from equal temperament significantly. These contrasting notions are explored through an examination of two historically opposed ideologies that concern consonance and dissonance. This thesis suggests that the aesthetic evaluation of twelve-tone atonal music may be informed by its theoretical limitation to the equally

In the thesis, partial coefficients for thermal cracking problems are determined with a probabilistic model. One crucial parameter influencing the risk of cracking is the restraint.

Abstract:
In early design phases new burner concepts are mostly tested in single or multi burner test rigs. These test rigs generally exhibit a different acoustic behavior than the full scale engine. The acoustic behavior, however, is crucial to predict whether thermoacoustic instabilities are likely to occur. Tuning the test rig’s acoustic boundary conditions to that of the engine could overcome this issue. Through this, an effective assessment of new burners is possible even in early design phases. In this work a method is proposed, which uses an active control scheme to manipulate the acoustic bounda

Abstract:
Energy efficient systems and environmentally friendly solutions are the focus of many commercial development projects. Current refrigeration technology carries a significant share of global energy consumption and exploring alternative refrigeration principles has become increasingly important. Shape memory alloys (SMA’s), especially Nickel-Titanium (NiTi) alloys, generate a large amount of latent heat during solid-state phase transformations, which can lead to a significant cooling effect in the material. These materials not only provide the potential for an energy efficient cooling process, t

Abstract:
Abstract The deterioration of model uncertainties is an important factor restricting the control performance for hydraulic servo systems. This paper proposes a fuzzy-based adaptive model predictive control (MPC) method with a linear extended state observer (LESO) for such systems. The LESO is employed to estimate the total disturbances and other unmeasured states to predict system behavior. Based on the constructed objective function, the optimal output sequence is obtained via the receding horizon and repeating optimization. As for the output feedback MPC, the influence of key parameters on o

Abstract:
An investigation to flow test and measure a large set of orifice plates to determine the proportion of existing orifice plates have measured discharge coefficients outside of the Reader-Harris/Gallagher equation 95% confidence limits. The research determined if the existing tolerance specifications adequately describe the dimensions of an orifice plate required to conform to the Reader-Harris/Gallagher equation calculated discharge coefficient. The testing also underscored the influence of manufacturing variations on orifice plate performance.

Abstract:
As part of a testing service agreement with Walter Marine and Atlantic Reefmaker, a 1:5.2 physical model of the Reefmaker Wave Attenuator was constructed and tested by the US Army Engineer Research and Development Center to evaluate its influence on wave attenuation. The tested prototype wave periods ranged from 2.5 to 8 sec with prototype wave heights between 1 ft and 6.5 ft. The Reefmaker Wave Attenuator included orthogonal and square designs and was tested under a variety of configurations including a suspended configuration, a bed-mounted configuration, and a rotated configuration.

Abstract:
The National Reference Laboratory for Air Quality (NRL) ensures the high quality of air quality measurements in Finland by organising audits and intercomparison campaigns. In this project, the conformity of the particulate matter measurements was evaluated with a particular focus on the measurement used for calculating the average exposure index (AEI) of Finland. The representativity and applicability of the AEI measurements made at the Kallio station in Helsinki were evaluated. It was noticed that the results of the Kallio measurement represent well the average fine particle (PM2.5) concentra

Abstract:
Lateral earth pressures in unsaturated soils undergo variations with changes in suction due to infiltration. The infiltration-induced alterations in the pressure head present a coupled hydromechanical problem, where interactions between solids and fluids influence the outcomes. However, existing analytical solutions for determining lateral earth pressures in unsaturated soils do not consider the effects of hydromechanical modeling. This paper presents analytical solutions for coupled hydromechanical modeling of lateral earth pressures in unsaturated soils. For this purpose, an analytical solut

Abstract:
: The necessity to improve broiler thermotolerance and performance led to the following hypothesis: (a) thethermoregulatory-response threshold for heat production can be altered by thermal manipulation (TM) during incubation so as to improve the acquisition of thermotolerance in the post-hatch broiler;and (b) TM during embryogenesis will improve myoblast proliferation during the embryonic and post-hatch periods with subsequent enhanced muscle growth and meat production.

Abstract:
The large-opening drum-honeycomb-type quad-strut suspend-dome structure is a new type of suspend-dome structure, which was improved from the traditional cable dome structure. It replaces the top chord of the cable dome with seamless steel pipes. The structure combines the characteristics of the suspend-dome and the cable dome. The bottom chord nodes connects four struts, two inclined cables and one ring cable. The Ansys finite element model is established to analyze the influence of initial prestress, rise-span ratio, thickness-span ratio, opening span and bottom chord arrangement schemes on t
