Irk

The birth planet of the Irken race was once, in prehistoric times, a living planet filled with all kinds of ecosystems and many types of fauna and flora. Now, it's nothing more than a gigantic metal ball.

Irk, as the name suggests, is the habitat of the Irken species, a reptilian, insectoid, semi-amphibian intelligent species that currently could be considered a race of cyborgs, as they use bioengineering to live.

Over the years, Irk went from being a wandering planet in the Nova Irkarus 720 solar system to a fixed planet in said system because, at some point, it was drawn into the gravitational field of the sun, nicknamed Alpha Ikarus star.

Irk has around 3 moons called Pendora, Ignis, and Mortem, the main one being Ignis, shining with a powerful pink glow, Mortem the second shining with a strong purple, and Pendora with a faint blue, being the smallest moon.

There isn't much recorded history of ancient Irk, so it's often not considered much when summarizing the planet's history.

Meanwhile, modern Irk is somewhat complicated.

Over the years, the planet has undergone many changes, from the force fields surrounding it, to using its core as an energy source in addition to electricity.

Irk can be divided into three rings: the surface, the subsurface, and the incinerator. The latter is somewhat self-explanatory but is essentially what precedes the core, where all of Irk's waste is thrown to feed the planet's core and keep it running.

The subsurface, or the main smelting area, is where the entire process of incubation and basic academic education for all Irkens happens.

It's equipped with thousands of machines including incubators, teaching machines, as well as other machines maintaining order like the sentinels. There are also departments serving as provisional homes for the smeets and their flesh-and-bone tutors.

Some families with smeets stay here until the smeets turn 10 and can go to their current surface homes, while in other cases, smeets are left here until that age.

That's the case for non-mutant smeets, as mutant smeets are of little importance and can surface as long as they are with an adult Irken from the subsurface.

Mostly, however, they stay underground until they turn 10.

The surface is where the majority of the population resides, both Irkens and other races allowed to live there, having lost their planets or having a population of fewer than 50, or being a labor force.

These races include the 3 branches of the Artifex, the Couwlek, Sraigo, Polum, who reside along with mutants in the southern area of Irk known as the slums or the never-dawning zone, as it's mostly in semi-darkness.

Due to the mix of species, there's a culture amalgamated from various cultures and a common language known as Joik, besides Irken and other languages, leading to a unique southern accent, sometimes hard to follow (akin to merging Scottish and Chilean accents).

The northern zone, known as the affluent districts or the eternal day zone, is exclusively inhabited by non-mutated Irkens or Irkens with low-importance mutations like Linea Linea and Alis Alis variants, without any other race present.

Only Irken is spoken here, with varying pronunciations based on the region, but it remains Irken overall and doesn't usually have a pronounced accent like the southern one.

Then there's the center or the privileged zone where high-ranking Irkens, elites, or celebrities, irrespective of faction (north or south), reside. It's also where significant events, such as the arrival of the highest authorities, take place.

Irk has a peculiar climate, mainly characterized by technically no wind, or at least no strong winds, but frequent rain—around 60% of the time. When it's not raining, it's cloudy or there's a dry but scarce wind blowing.

Temperatures are generally warm but can get hot, with longer periods of cold causing snowfall due to excessive moisture.

Fauna and flora are almost nonexistent in this concrete and metal jungle, with very few living specimens preserved, protected, or kept as pets.

Clear examples include Tei Tei hounds, Qiwed birds (resembling a mix of falcon and vulture), and large Xquima felines, along with the recurring Rod-Ei rodents, as part of the fauna.

Regarding flora, some tree and plant species are still conserved, like the Angel's Calla Lily flowers or Angelis flowers, which usually bloom if someone in the household where the plant is located dies.

There are also indigenous fruit and vegetable species cultivated on the Pendora moon, as it's most suitable for growing these crops, supplying a significant portion of the planet.

There are livestock species like Kiba, a mix of pig, cow, goat, and sheep, providing all that these four animals offer in one, and Fei Fam, a mix of turkey, goose, and chicken providing eggs, both raised in Mortem.

Lastly, there's a species akin to eel and a mix of salmon and tuna called Rifem, also bred in Mortem for consumption. These products are exported and sold in markets or shops.

Ignis, on the other hand, is a moon used entirely for industrial purposes, essentially housing thousands of factories and warehouses, including the first still-functional quarantine station.

Most technology, from ships, weapons, and armors to simple household appliances, is manufactured in Ignis. There's also a small PAK factory operating 24/7.

Irk is surrounded by two strong force fields keeping it safe, projected by a gigantic artificial metal ring, creating a second exosphere and a second stratosphere. The second field is the stronger one between the two shields.

These shields allow entry and exit of ships only if they have a special seal allowing passage. The shields have detectors preventing anything without the seal from entering.

the months and the passing of time

the time passing on irk is certainly a slow process,with a day of aproximately 30 hours of wich 15 are day and the other 15 are night,tho during certain periods of time theres only 7 hours of day while the other 23 lefth are night or vice versa.

with 12 months of 40 days and weekends of 10 days each,a year of aproximetly of 480 days wich are divided in 120 days for each seasson,the time period on irk is certainly long.

in fact tho for irkens and the other races living in irk the time passege is like this while on irk outside of the planet the time is different as an example for humans an irken year is the equivalent of around 12 human years,since each irkean month is a year for humans.

the irken months are called of the following way,premerc the first month of the year,loter,shiofer,doika,okaltek,muna,kuna,irter,lunaria,soikot,jurtia and ultum the last month of the year.

Seasons

The seasons on Irk, like on Earth, are four, but they're not entirely the same since there isn't exactly spring or autumn, rather something akin to winter and summer.

The snowy season, also known as Crystel, is characterized as Irk's winter equivalent. During this season, snow falls heavily, occasionally accompanied by hail. Temperatures drop, and the typically absent wind blows as a freezing breeze that penetrates to the bone.

The Artifex are among the races most prepared for this season as they are highly resistant to the cold and harsh environment. They're the only creatures on Irk capable of 'swimming' effortlessly through the snow and ice.

Upon the arrival of this season, Irkens tend to feel more drowsy, move much slower, and their usually high body temperatures rise. Many theorize that if Irkens were a more peaceful race, they would likely hibernate during this period.

Irkens alter their sleep patterns, sleeping many more hours during this time. Additionally, Irkens with fur develop denser coats against the cold. Those with more insectoid wings, not of the moth or butterfly type, shed them as they don't withstand the cold well.

Mutated Irkens lacking the mentioned characteristics don't usually fare well during winter, especially those with reptilian, amphibian, or insectoid features without fur, as mutants seem more susceptible to the cold.

The next season is the rainy season called Lacrimus. As implied, it rains incessantly throughout this season, sometimes causing floods. The air is humid with fog, surprisingly, this is the only season with strong winds alongside continuous lightning.

During this time, blackouts are common, so all Irkens and underlying races have emergency generators, especially in the southern zone, where there are high risks of floods as it's technically a basin where water collects.

Often, Irkens are allowed to stay home and not work due to the risks posed by this extreme rainy season, mainly because of the sudden water surges that sometimes occur, lightning strikes, or the inability to leave homes due to flooding.

Mutants with aquatic traits and the Polum are better adapted for this season due to their aquatic adaptations, experiencing fewer difficulties throughout the period.

This is generally the most disliked season by Irkens and other races due to the numerous problems it brings, being one of the most challenging seasons to endure.

The following season is the opposite of the wet season, known as Fercius, the equivalent of summer. It's characterized by intense drought, with only a 10% chance of rain during the three months and scorching temperatures.

Mutated Irkens with reptilian and insectoid characteristics, as well as the Couwlek race, fare well during this time as they're prepared to handle the heat.

Meanwhile, normal Irkens and other mutations struggle a bit as they're not built for intense heat and the almost non-existent but devastatingly hot breeze and intense sun during this period.

It's not uncommon to see people using umbrellas and hats against the sun or individuals fainting in the middle of the road due to the incredibly hot temperatures of these periods.

Contrarily, nights, like a desert, are cold and cool but very brief. This is the time when a day lasts 23 hours, and the night only 7.

Lastly, the fourth and final season, Nocturnia, also known as the eternal night season because here, unlike Fercius, the night lasts 23 hours and the day 7, hence its name, emphasizing its main characteristic.

During this season, Irk is almost entirely in penumbra, barely illuminated by the sun. Irkens prevail thanks to their night vision and the intense neon lights of the gigantic metropolis.

This season is the only one on Irk that doesn't feature extreme changes like rain, cold, or heat. It's mild with the normal percentage of rainfall in Irk, technically Irk's spring, but without plants and allergies.

Mutant Irkens, having developed in some cases glowing marks in the dark, technically have it easier than average Irkens during this season, similarly, Sraigo with their bioluminescence.

Throughout this season, there are constant meteor showers illuminating the almost perpetually nocturnal Irken sky, rendering it a vibrant pink color akin to Irk's daytime sky.

During Nocturnia's duration, a phenomenon similar to the aurora borealis occurs every few nights, along with the always-awaited triple lunar eclipse, turning Pendora yellow, Mortem red-orange, and Ignis green for one night.

Its widespread use spans various industries, including aerospace, automotive, and power generation, due to its ability to quickly and accurately identify defects without causing damage. Central to the effectiveness of ECT are the tools, probes, and techniques used during inspections. This article provides an in-depth look at the key components and considerations involved in eddy current testing.

Core Components of Eddy Current Testing Equipment

Eddy Current Instruments The primary component of ECT is the eddy current instrument or tester, which generates an alternating current to produce a magnetic field in the probe coil. When this probe is placed near a conductive surface, it induces eddy currents within the material. The instrument measures changes in these currents, which can indicate the presence of defects, material thickness variations, or conductivity changes.

Modern ECT instruments range from portable handheld devices to sophisticated desktop systems with advanced data analysis capabilities. Features such as multi-frequency testing, real-time data visualization, and automated defect analysis enhance their versatility and accuracy in various applications.

Probes and Coils Probes are critical for effective eddy current testing. They come in various shapes and configurations, tailored to specific testing requirements and material properties. Selecting the right probe is crucial for achieving accurate results. Here’s a breakdown of common probe types:

Pencil Probes: These are versatile probes ideal for testing small, localized areas such as cracks in welds or holes. Pencil probes offer high precision but require a steady hand during inspections.

Surface Probes: These probes are used for inspecting larger, flat surfaces and can detect surface cracks, corrosion, and thickness variations. Surface probes often feature multiple coils for greater sensitivity and faster scanning.

Encircling Coils: As the name suggests, these coils encircle the test piece, making them suitable for cylindrical components such as pipes and rods. They’re commonly used for testing for defects like cracks, seams, and material inconsistencies.

Differential Probes: These probes compare signals from two adjacent points, providing high sensitivity to small changes. They are effective for detecting localized flaws and are commonly used for detecting cracks in tubing and thin materials.

The Pros and Cons of Different Bridge Inspection Technologies

Bridge inspections are critical to ensuring that some of our country’s most crucial infrastructure elements stay structurally sound and safe.

Bridge inspection technology is key to ensuring that these inspections are as accurate and undisruptive as possible. 

The technology used to inspect bridges has rapidly increased in sophistication over the past 20 years. 

What was once done with chains and boots-on-the-ground is now possible with airplanes and infrared technology. Although there is still a place for older methods of bridge inspection. 

In this article, we’ll walk you through some of the different forms of bridge inspection and outline what scenarios each method is ideal for.

Visual Inspection

Visual inspection remains a fundamental aspect of bridge assessment, serving as a starting point for identifying obvious defects. 

This method is cost-effective and requires minimal equipment, allowing inspectors to detect surface-level issues like cracks, spalling, and corrosion.

 It also enables immediate identification of urgent repairs, which can be crucial for maintaining public safety. 

However, visual inspection has its limitations. It's restricted to surface-level defects and can be highly subjective, depending on the inspector's expertise. 

Visual inspections can be time-consuming for large structures and may miss subsurface issues that could compromise the bridge's integrity.

Visual inspections are usually paired with other auditory and tactile techniques.

Acoustic Techniques

Bridge inspectors can detect damage to bridges using acoustic methods, such as chain dragging and hammer sounding.

The different sounds that are made when applying chains or hammers to the bridge’s surface indicate whether there are fractures, or delaminations, within the bridge’s structure.

These techniques are relatively inexpensive and easy to implement, requiring minimal training for inspectors. 

However, acoustic techniques are not without drawbacks. They are labor-intensive and time-consuming, especially for large bridge decks. 

The results are subject to human error and interpretation, which can lead to inconsistencies in assessments. Additionally, these methods are not effective on bridges with asphalt overlays and have a limited depth of detection.

They also require bridges to be shut down to traffic, which can frustrate the public.

Thermal Infrared (TIR) Inspection

Thermal Infrared (TIR) technology is a scientific tool for bridge inspections that is more accurate and hands-off than traditional techniques. 

Here’s how it works: TIR tech detects temperature differences within a bridge’s structure, which indicate issues such as delamination

However, several different ways are available to collect TIR data, and some are less disruptive than others.

TIR With Mobile, Ground-Based Vehicles

Mobile, ground-based vehicles equipped with TIR cameras offer a practical solution for bridge deck inspections. 

These vehicles can cover large areas quickly, minimizing traffic disruption and allowing for consistent data collection at highway speeds. 

This approach is particularly useful for assessing long bridge spans or multiple bridges in a single session. 

However, ground-based TIR inspections are limited to deck surfaces accessible by vehicle, which may exclude some bridge components. 

In some cases, lane closures may be necessary, causing temporary traffic inconveniences. 

Additionally, this method is less effective for inspecting the undersides of bridges, which can be critical areas for detecting structural issues.

TIR With Fixed-Wing Aircrafts

Fixed-wing aircraft equipped with TIR cameras offer a comprehensive solution for bridge inspection technology. 

This method can survey multiple bridges in a single flight, providing a wide-area perspective that is particularly efficient for large-scale infrastructure assessments. 

Aircraft-based TIR inspections cause minimal traffic disruption and can capture both deck and underside imagery, offering a more complete view of the bridge's condition. 

However, this approach has higher initial costs compared to ground-based methods. It's also weather-dependent, which can lead to scheduling challenges. 

Special permits may be required for low-altitude flights, adding to the logistical complexity. 

While aircraft-based TIR provides excellent coverage, it may offer less detail than close-range inspections.

TIR With Unmanned Aerial Vehicles (UAVs) or Drones

UAVs or drones equipped with TIR cameras have gained popularity in bridge inspection due to their versatility. These devices are highly maneuverable, allowing access to difficult areas that might be challenging or dangerous for human inspectors.

 They can capture high-resolution imagery and are cost-effective for individual bridge inspections, causing minimal traffic disruption. 

However, drones have limitations in flight time and range, which can be problematic for large bridges or extensive surveys. They are also susceptible to wind and weather conditions, potentially affecting data quality or preventing inspections altogether.

 Operating drones requires skilled pilots and compliance with aviation regulations, which adds to the complexity of this method.

Other Non-TIR Bridge Inspection Technologies

While thermal infrared solutions offer significant advantages, other bridge inspection technologies also play important roles in comprehensive assessments.

Ground Penetrating Radar (GPR)

Ground Penetrating Radar is a non-destructive testing method that uses electromagnetic pulses to detect subsurface defects and rebar corrosion in bridge structures. 

It has the advantage of working through asphalt overlays and providing depth information, which is crucial for assessing the internal condition of bridge decks. 

However, GPR requires specialized equipment and expertise to operate effectively. Data interpretation can be complex, requiring trained professionals to analyze the results accurately. 

While GPR is excellent for detecting certain types of defects, it is less effective than TIR technology in identifying delaminations.

Final Thoughts

As bridge inspection technology continues to evolve, engineers and inspectors have an array of tools at their disposal. 

Thermal infrared solutions, particularly those deployed via fixed-wing aircraft, offer a compelling combination of efficiency and effectiveness for large-scale bridge assessments. 

However, less sophisticated bridge inspection techniques still have their place in infrastructure assessment. 

When selecting bridge inspection technology, factors such as bridge type, size, location, and specific inspection goals should be considered. By leveraging the strengths of different inspection methods, agencies can develop more effective maintenance strategies, ultimately ensuring the safety and longevity of our critical infrastructure. 

The future of bridge inspection lies in the intelligent integration of these diverse technologies, which would create a more robust and efficient system for maintaining our vital transportation networks.
