Mobile Base Station Architecture Evolution and Synchronization Challenges: Role of IEEE 1588 PTP in 5G Networks

This paper proposes an innovative hazard identification and risk assessment mapping model for Urban Search and Rescue (USAR) environments, concentrating on a 3D mapping of the environment and performing grid-level semantic labeling to recognize all hazards types found in the scene and to distinguish their risk severity level. The introduced strateg...

This paper proposes a novel Deep Learning (DL)-based approach for classifying the radio-access technology (RAT) of wireless emitters. The approach improves computational efficiency and accuracy under harsh channel conditions with respect to existing approaches. Intelligent spectrum monitoring is a crucial enabler for emerging wireless access enviro...

This paper presents a strategy to autonomously explore unknown indoor environments, focusing on 3D mapping of the environment and performing grid level semantic labeling to identify all available objects. Unlike conventional exploration techniques that utilize geometric heuristics and information gain theory on an occupancy grid map, the work prese...

We investigated the use of a Deep Learning approach to radio signal de-noising. This data-driven approach has does not require explicit use of expert knowledge to set up the parameters of the denoising procedure and grants great flexibility across many channel conditions. The core component used in this work is a Convolutional De-noising AutoEncode...

Urban search and rescue missions require rapid intervention to locate victims and survivors in the affected environments. To facilitate this activity, Unmanned Aerial Vehicles (UAVs) have been recently used to explore the environment and locate possible victims. In this paper, a UAV equipped with multiple complementary sensors is used to detect the...

Around 50 billion dollars is spent yearly on therapy for low back pain in the United States alone. Low back pain is one of the most common reasons for doctor visits. Having poor posture has been found to be a main cause of lower back pain as it impacts the transverse abdominal muscle. Maintaining a good posture and changing position from time to ti...

The emerging in vivo communication and networking system is a prospective component in advancing healthcare delivery and empowering the development of new applications and services. In vivo communications is based on networked cyber-physical systems of embedded devices to allow rapid, correct and cost- effective responses under various conditions....

High Peak-to-Average-Power Ratio (PAPR) of transmitted signals is a common problem in broadband telecommunication systems using an orthogonal frequency division multiplexing (OFDM) modulation scheme, as it increases transmitter power consumption. In consumer applications where it impacts mobile terminal battery life and infrastructure running costs...

This paper proposes a novel glove-based system for hand-gesture recognition. The system tracks fine-grain hand movements using inertial and attitude measurements. Gestures are recognized in real-time by feeding the sensor readings to a machine-learning algorithm. In addition, gestures are communicated wirelessly to external devices for display and...

This paper presents an online controller for regulating the throughput of instruction-sequences in multicore processors using dynamic voltage-frequency scaling. The proposed control law comprises an integral controller whose gain is adjusted online based on the derivative of the frequency-throughput relationship. This relationship is modeled as a s...

This paper presents an online controller for tracking power-budgets in multicore processors using dynamic voltage-frequency scaling. The proposed control law comprises an integral controller whose gain is adjusted online based on the derivative of the power-frequency relationship. The control law is designed to achieve rapid settling time, and it's...

Cache systems are on-chip memory elements used to store data that are frequently referenced by programs. The advantage of storing data in cache, as compared to RAM, is that it has faster retrieval times, but it has the disadvantage of on-chip energy consumption. A cache-decay interval is the amount of time a cache element holds unreferenced data be...

In this paper, we employ a linguistic-processing approach to the content-based retrieval of music information. Central to the approach is the use of a lossy version of the Lempel-Ziv incremental parsing (LZIP) algorithm, which constructs a dictionary by incrementally parsing music feature vectors. LZIP is adopted as a source characterization techni...

We apply pattern recognition techniques to enhance the robustness of moment-invariants-based image classifiers. Moment invariants exhibit variations under transformations that do not preserve the original image function, such as geometrical transformations involving interpolation. Such variations degrade the performance of classifiers due to the er...
