This document discusses radiation hardening techniques for digital circuits. It begins by explaining the need for radiation hardening in circuits used in space, military, and nuclear applications. It then covers various radiation sources and their effects on digital circuits like single event upsets. The document discusses two main approaches to radiation hardening - hardening by process which uses wide bandgap substrates, and hardening by design which includes techniques like triple modular redundancy, diode-based SEU clamping, and error correcting codes. It concludes that radiation hardening is essential for space applications but adds area and power overhead.
This document discusses radiation hardened chips. It defines radiation and describes the problems it can cause in electronics, such as ionization that leads to electric noise and signal spikes. This is a serious issue for devices used in space, around nuclear reactors, and during nuclear explosions. Radiation comes from sources like the Van Allen belts, cosmic rays, and residual radiation in packaging materials. The effects on electronics include total ionizing dose effects and single event upsets. To address this, chips are radiation hardened through design and manufacturing process techniques. There is a need for these hardened chips due to the hostile radiation environment in space.
Radiation hardened chips are designed to resist damage from ionizing radiation like that encountered in space, around nuclear reactors, and near particle accelerators. They use techniques like hardened substrates, shielding, and error correction to prevent issues like data corruption from radiation. Major sources of damaging radiation include Van Allen belts, cosmic rays, solar particles, and nuclear reactions. Radiation hardening aims to let electronics reliably function in radiation-intensive environments like satellites and nuclear facilities.

The document describes a Standoff Explosive Detection System (SEDS) that can detect explosives from up to 20 meters away using thermal neutron activation analysis. SEDS uses a pulsed beam of neutrons to induce gamma ray emissions from nitrogen, chlorine, and copper in explosives. A large gamma ray detector then senses these gamma rays to detect and locate explosives within 10 seconds while penetrating materials like concrete and steel. The system is designed to be low cost, safe for operators, and deployable within 12 months of adequate funding.
Industrial radiography uses X-rays and gamma rays to evaluate materials and objects without damaging them. It has applications in many fields including manufacturing, transportation, infrastructure inspection, security screening, and food processing. Some examples given are using radiography to detect defects in ceramic castings and battery electrodes, inspect bridges and aircraft parts, screen luggage and cargo for explosives, and treat food to kill bacteria and delay spoilage. Radiography is also used in other non-destructive applications such as geology, art conservation, and archaeology.

Optimal Generation of 254nm ultraviolet radiationIOSR Journals
Abstract: The science of the application of 254nm UV from mercury doped glow discharge tubes has been a major topic since Johann Ritter discovered UV via its chemical inducing reactions in 1801 and Niels Finsen’s 1860 work on UV therapy in treating rickets. In 1857 Siemens AG patented UV254nm creation via filamentary discharge, subsequently widely used for ozone production. By 1932 the Coblentz Congress had defined the three regions of the UV action spectrum. This paper presents the science of a new design for a sterilizer module fabricated from extruded, recycled aluminium. This novel design achieves better than D10 performance using six UV tubes per module driven by three electronic ballasts drawing a total current of only 1.26 amps at 240V single phase. This module delivers more than 45,000 microwatts per square centimetre of 254nm UV which sterilises one litre per second in a module with a dwell time of 1.6 seconds in a design with less than 0.5 bar pressure drop across each module. This system takes the electrical efficiency of 254 UV generation from less than 25% to more than 92% as measured by an NPL-traceable calibration against a current industry standard. Since 254nm UV generating tubes are also the basis of fluorescent lighting this new work on optimising the generation of 254nm UV also has application worldwide to improved efficiency of fluorescent tube electrical lighting, because we have shown that most of the fluorescent lamps operating today (particularly the T8 1” diameter) are running at less than 25% efficiency as opposed to the over 92% which is possible with the methods we describe. The work reported here shows that the Townsend equation for electron transport in glow discharge plasmas is not adequate since it does not address either plasma diameter or plasma drive frequency both of which fundamentally alter the electron energy transfer efficiencies to mercury atoms in the plasma.

Introduction
Access to clean drinking water in underdeveloped areas of the world is a growing problem due to global increases in both population and pollution. Current methods of water treatment are impractical to apply in many parts of the world, as these technologies are expensive, require large facilities staffed by a litany of professionals, and the production/disposal of treatment chemicals that often have negative environmental impacts. The need to develop a method of water treatment that is less expensive, operates without the use of chemical treatments, and has relatively low electrical power usage is of profound importance. One of the most viable and promising optionsoptions is to make use both cavitation and ultraviolet light (UV). The purpose of this project is to develop a system for researching the combined effects of these two forms of water purification.
Cavitation occurs when the static pressure of water drops below vapor pressure. Small microbubbles form and slowly collapse in an energetic manner. As cavitation bubbles collapse, temperatures within the bubble can reach upwards of 5000 degrees Kelvin. Due to pyrolytic decomposition that takes place within the collapsing bubbles, the OH radicals and shock waves arecan be generated at the gas–liquid interface (A. Agarwal et al, 2011). These radicals degrade contaminants suspended within the water that would otherwise resist ultraviolet degradation. This makes cavitation a promising method of water treatment.
Ultra violet light is capable of killing bacteria and living contaminants in water. Short wavelength UV light, in the range of 10 nm to 400 nm, kills cells by interacting with their structures and disrupting DNA (NIOSH, 2008). UV light is capable of killing up to 99.99% of bacteria in clear water. This system of water purification is both cost effective and nontoxicchemical free but it cannot break down particle contaminants that bacteria tend to live in. However in combination with a particle filtration system, or in our case a cavitation system, UV reactors are simple to maintain, cost effective and chemical free.
The concise purpose of this team’s senior design project will be to develop a fluid flow test apparatus to demonstrate the degree of effectiveness of the combination of UV radi.

This project aims to develop a sustainable solar powered ozone generator whose operating principle
is based on the production of ozone by corona effect. Ozone gas is now-a-days used for treatment of drinking
water, disinfection, and air-purification.Corona effect occurs when an intense electric field accelerates the
existing electrons around a conductor. This effect generates ozone through a high voltage process that produces
a strong enough electric field to break the dielectric strength of the air between the electrodes and breaks the
oxygen molecules and form ozone(O3). This phenomenon occurs at or near a field strength of 2kv-10kv. Flyback

Noise Analysis of Trans-impedance Amplifier (TIA) in Variety Op Amp for use i...IJECEIAES
VLC is a complex system with lots of challenges in its implementation. One of its problems is noise that originated from internal and external sources (sunlight, artificial light, etc). Internal noise is originated from active components of analog front-end (AFE) circuit, which will be discussed in this paper, especially on the trans-impedance amplifier (TIA) domain. The noise characteristics of AFE circuit in VLC system has been analyzed using the variety of available commercial Op Amp and different types of the photodiode (Si, Si-PIN, Si APD). The approach of this research is based on analytical calculus and simulation using MATLAB®. The results of this research show that the main factor that affecting the noise is e , the feedback resistor (R f ), and junction capacitor in the photodiode (C ). Besides that, the design concept of multi channel TIA (8 channel) using IC Op Amp, with consideration of pin number of each Op Amp, supply needs, the initial value of R f , converter to 8-DIP and feedback capacitor (C f j ) channel, also discussed in this paper.

Noise Analysis of Trans-impedance Amplifier (TIA) in Variety Op Amp for use i...IJECEIAES
VLC is a complex system with lots of challenges in its implementation. One of its problems is noise that originated from internal and external sources (sunlight, artificial light, etc). Internal noise is originated from active components of analog front-end (AFE) circuit, which will be discussed in this paper, especially on the trans-impedance amplifier (TIA) domain. The noise characteristics of AFE circuit in VLC system has been analyzed using the variety of available commercial Op Amp and different types of the photodiode (Si, Si-PIN, Si APD). The approach of this research is based on analytical calculus and simulation using MATLAB®. The results of this research show that the main factor that affecting the noise is e , the feedback resistor (R f ), and junction capacitor in the photodiode (C ). Besides that, the design concept of multi channel TIA (8 channel) using IC Op Amp, with consideration of pin number of each Op Amp, supply needs, the initial value of R f , converter to 8-DIP and feedback capacitor (C f j ) channel, also discussed in this paper.

IRJET- Wave Ultrasonic Testing and how to Improve its Characteristics by Vary...IRJET Journal
This document provides an overview of wave ultrasonic testing and how varying operational parameters can improve its characteristics. It discusses how guided wave testing using low frequencies below 100 kHz can be used to inspect pipes over long distances for corrosion detection. Commercial systems have been developed that use arrays of piezoelectric transducers to generate and control axially symmetric modes to identify non-symmetric features indicating defects. Varying the test frequency affects sensitivity, resolution, and range, with lower frequencies providing longer ranges but reduced resolution.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
