HART (Highway Addressable Remote Transducer) is a digital networking facility that allows any instrument, field device, or controller to be accessed for configuration and diagnostics from any point on the network. It uses frequency shift keying to send and receive data to connected devices using only two wires, without affecting the 4-20mA signal also carried by those wires. This enables centralized diagnostics and configuration of devices while retaining conventional analog signal transmission, providing the best of both digital and analog worlds.

Electro magnetic interference and compatibility(ECM,ECI)
Electromagnetic interference (EMI) can negatively impact electrical/electronic equipment by creating undesirable responses or failure. Electromagnetic compatibility (EMC) aims to allow equipment to function properly in the intended environment without degradation from EMI. EMI can be radiated through electromagnetic fields or conducted through physical contact. Common techniques to control EMI include grounding, shielding, and filtering. Proper layout design can also help prevent EMI and ensure EMC.

Introduction To Electromagnetic Compatibility
Here are a few key points about ground in the context of electromagnetic compatibility (EMC):
- Ground is a common reference point in an electrical system that all other voltages are measured against. It establishes a baseline voltage level.
- In EMC, ground plays an important role in providing a return path for electromagnetic interference (EMI) currents. These currents, known as common mode currents, flow on cables and are looking for a way to complete their circuit back to the source.
- An ideal ground would have zero impedance and instantly drain away any EMI currents. In reality, all grounds have some finite impedance that can allow currents to couple into other circuits.
- Different grounding schemes are used, such

236029677-Hart-Communication-Pptx.pptx
The document discusses the HART communication protocol, which defines a standard for sending and receiving digital information across analog wires between smart field devices and host systems. It describes how HART works by superimposing digital signals on top of the standard 4-20mA analog signal, allowing bidirectional communication at 1200 bits per second without interrupting the analog signal. Benefits of HART include access to device parameters and diagnostics, compatibility with existing equipment, and open interoperable standards.
Smart transmitter
A smart transmitter contains a microprocessor that allows for self-diagnostics, non-linear compensation, remote re-ranging without recalibration, and digital communication over a network. HART transmitters can communicate digitally by superimposing a digital signal on top of the 4-20 mA analog signal without interrupting it. Calibration of smart transmitters is still important to maintain accuracy over time as electronic components can drift, even though they are advertised as very accurate.

National Security Agency - NSA mobile device best practices
Threats to mobile devices are more prevalent and increasing in scope and complexity. Users of mobile devices desire to take full advantage of the features
available on those devices, but many of the features provide convenience and capability but sacrifice security. This best practices guide outlines steps the users can take to better protect personal devices and information.
Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
- These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.
