Design, Fabrication, and Testing of Anemr Gun Based Orbital Debris Impact Testing Platform


This paper describes the changes made from Cal Poly’s initial railgun system, the Mk. 1 railgun, to the Mk. 1.1 system, as well as the design, fabrication, and testing of a newer and larger Mk. 2 railgun system. The Mk. 1.1 system is developed as a more Continue reading

Robust Unconstrained Face Detection and Lip Localization Algorithm Using Gabor Filters


Automatic speech recognition (ASR) is a well-researched field of study aimed at augmenting the man-machine interface through interpretation of the spoken word. From in-car voice recognition systems to automated telephone directories, automatic Continue reading

An Auction-based Spectrum Leasing Mechanism for Mobile Macro-Femtocell Networks of IoT


The Internet of Things (IoT) is a vision of the upcoming society. It can provide pervasive communication between two or more entities using 4G-LTE (Long Term Evolution) communication technology. In 4G-LTE networks, there are two important Continue reading

On Transform Domain Communication Systems under Spectrum Sensing Mismatch: A Deterministic Analysis


Towards the era of mobile Internet and the Internet of Things (IoT), numerous sensors and devices are being introduced and interconnected. To support such an amount of data traffic, traditional wireless communication technologies are facing challenges Continue reading

NB-IoT for D2D-Enhanced Content Uploading with Social Trustworthiness in 5G Systems


Future fifth-generation (5G) cellular systems are set to give a strong boost to the large-scale deployment of Internet of things (IoT). In the view of a future converged 5G-IoT infrastructure, cellular IoT solutions such as narrowband IoT (NB-IoT) and Continue reading

Intra-Minute Cloud Passing Forecasting based on a Low Cost IoT Sensor—A Solution for Smoothing the Output Power of PV Power Plants


Clouds moving at a high speed in front of the Sun can cause step changes in the output power of photovoltaic (PV) power plants, which can lead to voltage fluctuations and stability problems in the connected electricity networks. These effects can be Continue reading

Support for Cell Broadcast as Global Emergency Alert System

Cell Broadcast (CB) is a possible technical realisation of a global emergency alert system. It is a technique used for sending short text messages to all mobile stations (MSs) in a defined geographical area. An potential effect of using CB is the increase in battery consumption of the Continue reading

Automobile Control Systems: Transition from Controller Area Networks to Ethernets

Due to concerns about the negative impacts of powering vehicles using fossil fuel and the future availability of fossil fuel, there has been an increased focus on electric vehicles. However, current electric vehicle energy efficiency is Continue reading

Energy Optimization Mechanism for Mobile Terminals using Vertical Handoff between WLAN and CDMA2000 Networks

This paper presents energy optimization mechanism for mobile terminals (MTs) using vertical handoff between Wireless LAN (WLAN) and CDMA2000 networks. Several techniques for optimizing the power consumption of MTs have been considered in literature. Some of these techniques could be used Continue reading
