Experimental Analysis

Central to good science are accurate observations, testable hypotheses, well-designed experiments or other tests, and reasonable data analyses. The purpose of this activity is to introduce the basics of designing and analyzing experiments. This is accomplished by using a computer simulation that involves the real-world industry of farming fish. The two laboratory exercises include further steps in organizing and analyzing data.

Experimental and Theoritical Analysis of Thermal Properties in Zephyr Bamboo Tali (Gigantochloa Apus Kurz)

Specific heat, thermal conductivity and thermal diffusivity of Bamboo panel are USAble to support the Programming of Design and Planning in the Structure of the Agricultural Building Construction. The Specific heat of Bamboo's fiber, sheet and panel using the method of mixtures varied from 1.585-2.789 J/gr oC, with a mean value of 2.227 J/gr oC in the temperature difference range of 9 ± 0.1oC . It was found it will increase linearly with an increase in the sample temperature. Thermal conductivity values of Bamboo's fiber based on the transient line heat source technique varied from 0.1035 x 10-3-0.1322 x10-3 J/ cm2 sec oC in the sample temperature 22 to 30 oC on thermal diffusivity of bamboo fiber in 22-30 oC was found to be 0.0823 x 10-3J/cm secoC. The sorption Isotherm and the water activity in the bamboo's panel is depend on the chemical composition, glue laminated, additive and the porosity. There are related with the absorbing of the water into the bounded water and the diffusivity of the water in and out the panel. The moisture equilibrium range are 7.89 to 19.22 percent in the control of the circumstances and 11 to 75 % of the environment.relative humidity

Propfan experimental data analysis

A data reduction method, which is consistent with the performance prediction methods used for analysis of new aircraft designs, is defined and compared to the method currently used by NASA using data obtained from an Ames Res. Center 11 foot transonic wind tunnel test. Pressure and flow visualization data from the Ames test for both the powered straight underwing nacelle, and an unpowered contoured overwing nacelle installation is used to determine the flow phenomena present for a wind mounted turboprop installation. The test data is compared to analytic methods, showing the analytic methods to be suitable for design and analysis of new configurations. The data analysis indicated that designs with zero interference drag levels are achieveable with proper wind and nacelle tailoring. A new overwing contoured nacelle design and a modification to the wing leading edge extension for the current wind tunnel model design are evaluated. Hardware constraints of the current model parts prevent obtaining any significant performance improvement due to a modified nacelle contouring. A new aspect ratio wing design for an up outboard rotation turboprop installation is defined, and an advanced contoured nacelle is provided

Experimental Analysis And Setup Of Gravity Assisted Shell And Tube Heat Exchanger

Heat transfer is one of the most important thing to be considered in thermal industry. There are several type of heat exchangers available for heat transferring purposes. But scientists are involved in finding new methodologies which would further increase the heat transfer rate and the effectiveness of heat transfer by conducting several experiments. Many researchers have found the different methodologies for increasing the heat transfer rate with the application of various research. In this paper we have proposed a new methodology for the heat exchanger in various aspects. In this paper we have proposed a new concept which can be uses in shell and tube heat exchangers. Here we have considered the angle of the heat exchanger to know whether the heat transfer rate increases or decreases with increase in inclination angles of the exchanger. Here we have used the heat exchanger in various angles from 0` to 90` to find at which angle the heat transfer rate is maximum. The experimental analysis shows the heat transfer rate is maximum at 45` and it increases further with increase in the mass flow rate of both the fluids. In this proposal we used water as both hot and cold fluid with varying mass flow rates of the liquids

Two-Stage Team Rent-Seeking: Experimental Analysis

This paper presents a two-stage team rent-seeking model with a contest prize that is not excludable among winning team members. When early effort is a perfect substitute for late effort, early actors can free ride on their late-moving teammates. However, when early and late efforts are complements, all team members exert positive effort levels. Asymmetries in early effort reduce effort choices for all late movers. The theory is tested with laboratory experimental methods. Although subjects overinvest relative to the Nash equilibrium in all treatments, chosen effort levels provide limited support for the model. Early movers exerted higher effort in the complement treatment, and second-stage effort choices were broadly consistent with best response functions. Surprisingly, in both single-shot and repeated play environments, early movers in the substitute treatment did not free ride, choosing effort levels similar to those of late movers. [excerpt

Time crystals: analysis of experimental conditions

Time crystals are quantum many-body systems which are able to self-organize their motion in a periodic way in time. Discrete time crystals have been experimentally demonstrated in spin systems. However, the first idea of spontaneous breaking of discrete time translation symmetry, in ultra-cold atoms bouncing on an oscillating mirror, still awaits experimental demonstration. Here, we perform a detailed analysis of the experimental conditions needed for the realization of such a discrete time crystal. Importantly, the considered system allows for the realization of dramatic breaking of discrete time translation symmetry where a symmetry broken state evolves with a period tens of times longer than the driving period. Moreover, atoms bouncing on an oscillating mirror constitute a suitable system for the realization of dynamical quantum phase transitions in discrete time crystals and for the demonstration of various non-trivial condensed matter phenomena in the time domain. We show that Anderson localization effects, which are typically associated with spatial disorder and exponential localization of eigenstates of a particle in configuration space, can be observed in the time domain when ultra-cold atoms are bouncing on a randomly moving mirror.Comment: 15 pages, 7 figures, version accepted for publication in Phys.
