This article investigates two current incarnations of ‘lo-fi’ music and questions the extent to which these subgenres are actually low in fidelity. In essence, mainstream ‘hi-fi’ productions use similar effects, such as filtering sound like a radio or adding noise vinyl record. To understand lo-fi today, this explores by hip-hop producer ambient producer, drawing upon analytical methods Alan Mo...

Frequency-Invariant (FI) beamforming is a well known array signal processing technique used in many applications. In this paper, an algorithm that attempts to optimize the frequency invariant beampattern solely for the mainlobe, and relax the FI requirement on the sidelobe is proposed. This sacrifice on performance in the undesired region is traded off for better performance in the desired regi...

Recall the greedy algorithm for non-metric facility location that was done in Lecture 4, which was obtained by formulating the problem as set cover. In this section we present a modified greedy algorithm for the metric facility location problem that achieves a constant approximation ratio. Let the facility location instance consist of clients D, facilities F , metric d on D ∪ F , and facility o...

The proposed system exploits Wi-Fi and GeoMagnetic fingerprintings aided by Inertial Measurement Unit (IMU). Basically, the system only consists of the off-the-self Wi-Fi Access Points (APs) and low-cost IMU, while no extra equipment is required. Since the accuracy of Wi-Fi fingerprinting heavily depends on the number of APs deployments, spatial differentiability, and the fluctuation of Receive...

The mobile traffic has grown rapidly with the popularity of smart mobile devices. To accommodate increasing traffic, heterogeneous network integration is considered as a viable solution. By overlapping the coverage of heterogeneous networks (e.g., the long-term evolution (LTE) and Wi-Fi integrated network), the mobile operators can use the offloading service (e.g., Wi-Fi offloading) to reduce n...

Background: Electromagnetic fields (EMF) with different intensities are widely used at home, offices and public places.Today, there is a growing global concern about the effects of human exposure to EMFs. Epilepsy is one of the most common chronic neurological diseases, affecting 50 million people of all ages worldwide. We aimed to investigate the effect of exposure to Wi-Fi radiation on epilep...
