Asset Utilization Metrics Propel a Revival in Safety Solutions
Health and safety in the workplace has not always been a primary consideration
in manufacturing environments. However, there is a renewed
interest in safety emanating from Europe, highlighted by the European
Norm standard EN 954-1, which is garnering interest
in Japan and North America. Safety
technology has progressed considerably since the
first emergency stop relay appeared on the market,
and the future will bring new developments
to this technology. Improvement in the implementation
of current safety standards is mutually
beneficial for the protection of both man and machine
with the reduction of workplace accidents, lost output, damage to
machinery, and insurance premiums while resulting in an increase in Overall
Equipment Effectiveness (OEE). Manufacturers are currently reevaluating
the safety aspects of their machines and devices so as to provide
the safest possible workplace environment.
A new generation of safety solutions have
emerged that are more effective in
preventing accidents, less costly to
implement, more easily to adapt, more
reliable than existing hard wired systems,
and results in an increase in Overall
Equipment Effectiveness.

Fault Diagnosis of a High Voltage Transmission Line Using Waveform Matching A...ijsc
This paper is based on the problem of accurate fault diagnosis by incorporating a waveform matching technique. Fault isolation and detection of a double circuit high voltage power transmission line is of immense importance from point of view of Energy Management services. Power System Fault types namely single line to ground faults, line to line faults, double line to ground faults etc. are responsible for transients in current and voltage waveforms in Power Systems. Waveform matching deals with the approximate superimposition of such waveforms in discretized versions obtained from recording devices and Software respectively. The analogy derived from these waveforms is obtained as an error function of voltage and current, from the considered metering devices. This assists in modelling the fault identification as an optimization problem of minimizing the error between these sets of waveforms. In other words, it utilizes the benefit of software discrepancies between these two waveforms. Analysis has been done using the Bare Bones Particle Swarm Optimizer on an IEEE 2 bus, 6 bus and 14 bus system. The performance of the algorithm has been compared with an analogous meta-heuristic algorithm called BAT optimization on a 2 bus level. The primary focus of this paper is to demonstrate the efficiency of such methods and state the common peculiarities in measurements, and the possible remedies for such distortions.

Heterogeneous Performance Evaluation of Sophisticated Versions of CFAR Detec...Scientific Review SR
The detection of radar targets in a background, the statistical parameters of which are unknown and
may not be stationary, can be effectively achieved through CFAR processors. The CA-CFAR scheme performs
optimally for homogeneous and exponentially distributed clutter observations. However, it exhibits severe
performance degradation in the presence of outlying target returns in the reference set or in regions of abrupt
change in the background clutter power. The OS-CFAR processor has been proposed to alleviate both of these
problems. Although this processor may treat target multiplicity quite well, it lacks effectiveness in preventing
excessive false alarms during clutter power transitions. The TM -CFAR algorithm, which implements trimmed
averaging after ordering, can be considered as a modified version of OS technique. By knowingly excising the
ordered samples, the TM detector may actually perform somewhat better than the OS processor. To
simultaneously exploit the merits of CA, OS, and TM schemes, two combinations namely CA_OS and CA_TM
have been recently suggested. Each one of these versions optimizes good features of two CFAR detectors
depending on the characteristics of clutter and searched targets with the goal of enhancing the detection
performance under constant level of false alarm. It is realized by parallel operation of two standard types of
CFAR schemes. Our goal in this paper is to analyze these two developed versions, in heterogeneous situations,
to show to what extent they can improve the behavior of the conventional CFAR processors.

Defending Reactive Jammers in WSN using a Trigger Identification Service.ijsrd.com
In the last decade, the greatest threat to the wireless sensor network has been Reactive Jamming Attack because it is difficult to be disclosed and defend as well as due to its mass destruction to legitimate sensor communications. As discussed above about the Reactive Jammers Nodes, a new scheme to deactivate them efficiently is by identifying all trigger nodes, where transmissions invoke the jammer nodes, which has been proposed and developed. Due to this identification mechanism, many existing reactive jamming defending schemes can be benefited. This Trigger Identification can also work as an application layer .In this paper, on one side we provide the several optimization problems to provide complete trigger identification service framework for unreliable wireless sensor networks and on the other side we also provide an improved algorithm with regard to two sophisticated jamming models, in order to enhance its robustness for various network scenarios.

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).

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
