Determining the Ratio of Specific Heats of\\ Gases using Adiabatic Oscillations
The ratios of specific heats, γ = (CP/CV), for three gases (air, argon and carbon dioxide) were calculated by measuring the oscillations of different masses in various apparatus. The experiments followed Rüchardt's and Rinkel's methods; a 100ml glass gas syringe was additionally used to extend the investigation as well as a technique to elimination of friction. The approaches and results were compared; the most accurate method (Rüchardt's method alongside compensation for friction) yielded:
Air, γ = 1.358 ± 0.0038
Argon, γ = 1.6597 ± 0.0009
Carbon dioxide, γ = 1.2996 ± 0.0087
These differ from the literature value by 3.0%, 0.6% and 1.5% respectively. The reasons for these apparent discrepancies are discussed.

ETHZ_IR_2015_Proj2_G9 Assignment Report
We develop 3 term-based models(Naive tf, log tf, and BM25), unigram language model, and Pointwise
Online AdaGrad approach to select top 100 documents of each query. We use MIN((TP+FN),100) as
denominator when calculating AP. We also perform some methods in preprocessing and running stage to
obtain better MAP, as well less running time of the whole program. 2 rounds of scanning are needed in
our system.

Resonant enhancement of sensitivity in a Magnetic Tunnel Junction based Spin Torque Oscillator
In this work, we investigate the STO as a detector with in-plane geometry using field modulation Spin Torque ferromagnetic resonance (FM-STFMR), during which microwave signal is injected into the device and output response is measured in terms of RMS voltage across lock-in amplifier. The microwave signal injected externally to STO, efficiently synchronizes signal at two times the frequency of free oscillation of the nanomagnet (f0). The synchronization efficiently enhances signal sensitivity at 2f0 which opens other potential for development of spintronic devices. The effect of synchronization in STO under applied input RF power follows a consistent decrease in sensitivity with increasing power. Better synchronization at 2f0 is noticed above threshold current and shows good agreement with the results of numerical simulations.

Estimación de la gravedad mediante métodos experimentales
En esta práctica se utilizarán conocimientos de cinemática para encontrar el valor de la aceleración gravitacional, por medio de dos experimentos diferentes, uno que involucra la caída libre y el otro involucra un péndulo, además, se estimará la confianza y validez de los resultados.
