Abstract:

The Anti-theft security system designed to detect intruders and alert the user. The proposed system is built with a piezo sensor installed under the floor and a Raspberry Pi Pico W microcontroller. The piezo sensor detects the presence of an intruder and triggers an alarm, which is sent to the Raspberry Pi Pico W microcontroller. Microcontroller then sends a notification to the user, notifying them of the potential threat. The device includes a servo motor to control the camera angle. Piezo sensor detects the pressure and passes the signal to the Pi Pico W. The Raspberry Pi Pico W sends the in

Abstract:

The launch of the new mobile network technology has paved the way for advanced and more productive industrial applications based on high-speed and low latency services offered by 5G. One of the key success points of the 5G network is the available diversity of cell deployment modes and the flexibility in radio resources allocation based on user’s needs. The concept of Pico cells will become the future of 5G as they increase the capacity and improve the network coverage at a low deployment cost. In addition, the short-range wireless transmission of this type of cells uses little energy an

Abstract:

The use of heterogeneous networks (HetNets) that combine macrocells and picocells in the same coverage is effective in increasing system capacity and improving user throughput. The use of high carrier frequency bands is also expected to help achieving higher data rates because it promises vast amounts of signal bandwidth. Therefore, multiband HetNets with picocells operating at high carrier frequency bands have attracted significant attention with the aim of increasing system capacity and achieving a high user throughput in fifth-generation mobile systems and beyond.

Abstract:

This paper proposes interference-based decode and forward scheme that utilizes relay stations (RSs). In Long-Term-Evolution (LTE-) Advanced, heterogeneous networks in which femto- and picocells are overlaid onto macrocells are extensively discussed. However, interference between macro- and pico(femto)cells arises due to their different transmit power levels. Unlike conventional cooperative transmission schemes, the RS decodes interference in the first transmit timing period and forwards it to the user equipment (UE) in the second period. Moreover, cooperative transmission can be achieved witho

Abstract:

Heterogeneous networking of small cells such as pico/femtocells over the existing macrocell network is believed to augment the data rate requirement in forthcoming years. Closed access operation of femtocell base station (FBS) and shared spectrum assignment in the two-tier macro-femtocell network leads to unacceptable deterioration in achieved data rate of femtocell users. In this work, application of computationally efficient neural network to perform adaptive FBS transmit power control is proposed for mitigation of interference in two-tier heterogeneous network formed by macro-femtocells and

Abstract:

Road user fatalities account for one of the leading causes of preventable death in Latin America with pedestrians and bicyclists at higher risk for more extensive injuries as compared to other road users. Despite these vulnerable road user (VRU) risks, encouraging individuals to walk and cycle is an important public health strategy for addressing the region's obesity epidemic through promoting regular physical activity via active transportation (AT). However, in order to promote AT as a viable source of physical activity, safety of the VRU must be considered. Interventions to improve VRU safet

Abstract:

Loneliness and social isolation are subjective measures associated with the feeling of discomfort and distress. Various factors associated with the feeling of loneliness or social isolation are: the built environment, long-term illnesses, the presence of disabilities or health problems, etc. One of the most important aspect which could impact feelings of loneliness is mobility. In this paper, we present a machine-learning based approach to classify the user loneliness levels using their indoor and outdoor mobility patterns.

In order to decrease energy consumption caused by the dense deployment of pico base stations (PBSs) in heterogeneous cellular networks (HetNets), this paper first analyzes the energy efficiency (EE) of two-tier HetNets and then proposes a method to maximize the network EE by adjusting the PBS transmit power. The two-tier HetNets are modeled by the Poisson point process (PPP) and the Poisson hole process (PHP), and then the coverage probability of the macro base station (MBS) and the PBS in the two-tier HetNets is derived based on the mean interference to signal ratio (MISR).

The lipidic cubic phase method for crystallizing membrane proteins has posted some high-profile successes recently.

However, it is not a method that is used in every membrane structural biology laboratory and that is unfortunate. The reluctance in adopting it is attributable, in part, to the anticipated difficulties associated with handling the sticky viscous cubic me
