This document summarizes Professor Brian Evans' research group focusing on wireless networking and communications at the University of Texas. It outlines several completed and ongoing projects related to interference-aware communication systems and statistical modeling of radio frequency interference. These include developing statistical models of interference in wireless networks and powerline communications, as well as receiver designs and signal processing techniques to mitigate interference and improve communication performance.
The document discusses issues related to delivering infrastructure projects through the Private Finance Initiative (PFI) in the UK. It acknowledges that while some PFI projects have been ill-conceived or poorly procured, many have been successful with well-informed planning and good outcomes. It also notes criticisms of PFI and aims to provide an honest perspective on both the positives and challenges of the model.
The document discusses the Economics of Ecosystems and Biodiversity (TEEB) initiative. TEEB aims to demonstrate the value of biodiversity and ecosystem services, highlight the costs of biodiversity loss and benefits of action, and help decision-makers incorporate natural capital values into policy. The TEEB process involves outreach to policymakers, administrators, businesses and citizens to support tools that take biodiversity into account, such as incentive schemes, protected areas, and market reforms.
This document discusses severe sepsis and septic shock, which together affect over 500,000 Americans annually and have high mortality rates. Early Goal Directed Therapy (EGDT) following the 2001 Rivers trial has been shown to improve survival rates. While EGDT requires upfront resource utilization, this study from a community hospital found that after implementing an EGDT program, days on mechanical ventilation, ICU length of stay, and total hospital costs all decreased significantly. The cost per day was also lower for survivors versus non-survivors, suggesting EGDT can lower the overall cost of treating sepsis patients.
The document tests the Jiuzhou DTT6720 HDTV DVB-T PVR receiver. It can receive DVB-T channels in both MPEG-2 HD and H.264 HD formats using an STi7101 HDTV chipset. It has inputs like RF loopthrough, USB, Scart, RCA and outputs like optical and coaxial audio. The receiver is designed elegantly and can help address early issues with DVB-T providing unclear, pixilated pictures by receiving newer HDTV channels at high resolution to improve picture quality.
This document outlines a proposed wireless body area network (WBAN) system for ubiquitous and affordable healthcare. It begins with an introduction to WBANs and their use in continuous health monitoring. A 3-tier network architecture is proposed, consisting of wearable sensor nodes, a personal server, and a medical server. The document discusses the existing holter monitor system, proposed WBAN system capabilities, data flow, network positioning, system requirements, security considerations, applications, and comparisons to other wireless networks. Potential advantages include remote health monitoring and early disease detection, while challenges include interference between devices and lack of sensor integration.

Spatial Interference and It’s Effect Towards the Performance of 4G NetworkRosdiadee Nordin
The document discusses spatial interference and its effect on future 4G wireless networks. It provides background on the problem of spatial interference in multiple-input multiple-output (MIMO) systems which can degrade capacity. Previous works that attempted to address this issue through techniques like antenna separation, optimum power allocation, and subcarrier allocation are summarized. The proposed solution will look to further mitigate the effects of spatial interference in orthogonal frequency-division multiple access (OFDMA) systems.
This document provides an overview of a course on multi-antenna techniques and their applications. It discusses the use of multiple antennas to combat fading through diversity combining and spatial multiplexing to achieve higher data rates. It notes that while more antennas can improve performance, there are diminishing returns due to factors like mutual coupling between closely spaced antennas. The document also compares spatial multiplexing and diversity, noting that multiplexing transmits multiple streams for higher throughput while diversity transmits one stream redundantly for better reliability.
This document provides an overview of Li-Fi (Light Fidelity) technology. It discusses the history of using light for data transmission. It also describes how Li-Fi works by transmitting data using variations in light intensity that are undetectable to the human eye.

Why You Should Replace Windows 11 with Nitrux Linux 3.5.0 for enhanced perfor...SOFTTECHHUB
The choice of an operating system plays a pivotal role in shaping our computing experience. For decades, Microsoft's Windows has dominated the market, offering a familiar and widely adopted platform for personal and professional use. However, as technological advancements continue to push the boundaries of innovation, alternative operating systems have emerged, challenging the status quo and offering users a fresh perspective on computing.
One such alternative that has garnered significant attention and acclaim is Nitrux Linux 3.5.0, a sleek, powerful, and user-friendly Linux distribution that promises to redefine the way we interact with our devices. With its focus on performance, security, and customization, Nitrux Linux presents a compelling case for those seeking to break free from the constraints of proprietary software and embrace the freedom and flexibility of open-source computing.
zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

14. How do we fit the distributions?
2nd Order, Akaike Information Criterion
2K(K + 1)
AICc = −2 ln Lθ,data
ˆ + 2K +
n−K −1
AIC 1st order
ˆ
• Lθ,data maximum log-likelihood score over parameters θ
ˆ
• K number of parameters (=1,2 for us)
• n number of sample points (=4000 for us)
Lower scores imply better fits.

15. Stat fits: what we want
• First order stats: gives simple independent sample model for channel.
Ensemble amplitude distribution.
– Likelihood of having (in)sufficient receive signal strength
• Second order stats: level crossing rate, and fade durations
– Likelihood of dropping (1 or more) packets
– Likelihood of achieving latency requirements
– Indication of packet length

25. Conclusion
• Models are for using, not for demonstrating mathematical skill
• Beware models that match intuition: likely they are wrong!
• Good models make good simulators
• We built it: so you don’t have to
