GPR systems work by sending a tiny pulse of energy into a material via an antenna. An integrated computer records the strength and time required for the return of any reflected signals. Subsurface variations will create reflections that are picked up by the system and stored on digital media. These reflections are produced by a variety of material such as geological structure differences and man-made objects like pipes and wire.

Ground Penetrating Radar (GPR) is one of the safest and most reliable NDT (non-destructive testing) method to inspect concrete before you cut, core, or demo.

Ground Penetrating Radar is a geo-sensor which is used for detecting the target material which is inside the surface and not seen superficially. Surface may be different type like ground, wall, desert e.t.c. It is useful for detecting those material whose electrical characteristics may be nearly equal to inside surface electrical property. The best use of GPR is for detecting land mines.
Cavities detection with ground penetrating radar in limestone dominated rock ...Firman Syaifuddin
As one of geophysical method ground penetrating radar uses electromagnetic wave propagation to detecting the anomaly object, the strong relationship between the physical properties of geological material and their electromagnetic properties enable to identification of physical structures in the sub surface. Cavities in limestone dominated rock formation sometimes made problem when construction build above in this area, as prevention to the damage affected by cavities, before construction starting to build we have to identified the possible cave location to preparing special treatment to minimize the risk. Present of cavities give electromagnetic anomaly event and the reflection signal representing changing of electrical properties when we use ground penetrating radar. We applied attributes extraction adopted from seismic method to extracting information about cavities. We use sweetness attribute extraction to identified present of cavities in limestone dominated rock formation
This article documents the use of portable georadar for measuring the thickness of sea ice.
This device was developed to replace the method for measuring ice thickness by drilling ice
holes. The device based on the use of the LOZA georadar (ground penetrating radar, GPR)
and a specially developed method of field measurements when landing on the studied ice
formations. The study of the thickness and structure of sea ice by radar method is a complex
problem. The salinity of sea ice determines its significant conductivity, which, in turn, causes
a large attenuation of the electromagnetic signal of the georadar. The widespread GPR with
a pulse power of 50–100 W are not applicable for sounding sea ice precisely because of the
large signal attenuation. The LOZA instrument is equipped with a transmitter with a pulse
power of 1 MW. This is, on average, 10,000 times greater than that of “traditional” GPRs.
Multiple measurements of the thickness of ice formations, carried out on the one-year ice of the
eastern shelf of Sakhalin Island during winter expeditions of 2016 and 2019, have shown that
the device can quickly, accurately and with a high spatial resolution measure the thickness of
both flat and highly deformed ice (hummocks, rafted ice, and rubble field) over large areas.

PIPELINE PLANNING WITH AIRBORNE ELECTROMAGNETICSBrett Johnson
The costs of constructing a pipeline are highly dependant
on the relative occurrence of consolidated (rock) and unconsolidated (soil) material in the top
three metres of ground. Where rock occurs in the upper 3 metres, it has to be blasted which is far
more expensive than trenching through surficial soils. Helicopter electromagnetic (HEM) surveys are
used to map the electrical and magnetic properties as an aid to characterizing ground conditions in
advance of pipeline construction. An accurate determination of ground conditions can reduce
the planning risk
considerably.
Ground Penetrating Radar And 2-D Geoelectricity Application For Detecting Lan...IJERA Editor
The potential of landslide in some area in Abang district, Karangasem Regency, Bali, has been identified by
using ground penetrating radar and geoelectricity with dipole – dipole configuration. The Research has been
conducted in 6 sites. The interpretations of GPR and Geoelectricity revealed the presence of clay (8.52 cm/ns
and 11.8 – 18.6
m), saturated sand (12.11 cm/ns and 216
m) and water penetration (3.23 – 4.27 cm/ns
and 7.5 – 60
m) at 2 – 5 meter below the subsurface. The slip surface is detected at 5 – 8 m depth. The result
of sample laboratory test show high plasticity limit (27.13 – 24.51) and liquid limit (34.50 - 30.00) which leads
to landslide phenomenon.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

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).

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
