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.

Heat transport mechanisms for an end-heated aluminum rod
The contributions from conduction, convection, and radiation for an end-heated aluminum rod were quantified with experimental considerations in mind. Multiple experiments were carried out to ascertain various physical properties of the system and the aluminum rod. By applying heat-flow theory, simulations, and data-fitting techniques, the specific heat capacity, conductivity, emissivity, convective heat transfer coefficient of the system, and thermal contact resistance between the power source and aluminum rod were determined.
