For the proposed algorithm, we establish a global convergence estimate in terms of the objective value, and moreover present a dual application to the standard SCLP, which leads to

An OFDM signal offers an advantage in a channel that has a frequency selective fading response.. As we can see, when we lay an OFDM signal spectrum against the

• To achieve small expected risk, that is good generalization performance ⇒ both the empirical risk and the ratio between VC dimension and the number of data points have to be small..

We will design a simple and effective iterative algorithm to implement “The parallel Tower of Hanoi problem”, and prove its moving is an optimal

In this thesis, we have proposed a new and simple feedforward sampling time offset (STO) estimation scheme for an OFDM-based IEEE 802.11a WLAN that uses an interpolator to recover

3 recommender systems were proposed in this study, the first is combining GPS and then according to the distance to recommend the appropriate house, the user preference is used

Furthermore, based on the temperature calculation in the proposed 3D block-level thermal model and the final region, an iterative approach is proposed to reduce

According to the results, the following conclusions were drawn : (1) The maximum sound pressure gain is negative under frequency 1000Hz due to outer-ward pressure direction; (2)
