This requirement was for an international offshore drilling contractor that provides oilfield services for offshore oil & gas production, specialising in the ultra-deepwater sector. They needed ATEX Zone 2 rated load shackles with displays
and alarms for one of their deep water drillships that was being deployed off the Angola coast on the ultra-deepwater Kaombo project. Due to their clients stringent rules regarding hazardous areas, they needed certified products in order to comply. LCM Systems designed a system to meet their requirements that comprised of 3 x 12 tonne
environment, all cable supplied was RFOU (I) 250V armoured mud resistant power/instrumentation cable, specifically designed for safety critical systems in both EX and safe areas.
The load shackles were required to monitor the loads on umbilical roller sheaves as they payed out the hose to ensure that it did not become sagged and to check that the hydraulic hose reels were operating correctly. Each load shackle had its own display to show the individual loads, and all three were set to trigger an audio and visual alarm in the event of a pre-set limit being reached. A second display and alarm system was incorporated into the drilling cabin for remote system monitoring.
We subsequently received an identical order for the same system for another deep water drillship operator working on the same project.

We were contacted by a longstanding
customer about the feasibility of supplying them with a SOLAS compliant container weighing system. We had been supplying this specialist straddle carrier and forklift manufacturer with container weighing
systems for around five years, which they offered as an option on their straddle carrier range. With the introduction of updates to the SOLAS regulations, which stipulates that all containers must have a verified weight prior to shipping, they wanted a bespoke system to meet the standard that could be fitted to their equipment.
To meet the new legislative requirements, LCM Systems had to redesign the electronics of their existing system, and also introduce a new tablet display that showed the load on each individual pin and the total weight. Two existing load bearing pins were replaced with custom designed 25 tonne load measuring pins, which connect to an interface module where the mV/V output signal is converted to RS485 and the data then sent to the in-cab tablet display.
The new system was designed with pre-wired cable assemblies for connection to the interface module to allow installation to be carried out by untrained personnel, and also to facilitate fast and easy replacement of cables in the event of any becoming damaged. The tablet display, in addition to showing weight information, also has an in-built function that only allows the weight to be recorded once stable to ensure accuracy. It also includes a tare function and the facility to enter container numbers and generate reports.

Larsen & Toubro, a leading Indian engineering and construction contractor, were commissioned to build a nuclear containment building at Kakrapar Atomic Power Plant. As part of the project they needed to lift and position a 47 metre
diameter and 8.25 metre high inner containment dome liner, which had been built as a single unit. Because of the unique geometry of the dome and its 365 tonne weight, a balanced lift with equally distributed loads was vital to ensure a safe and successful lift. Eighteen lifting lugs were integrated into the dome liner, which were each fitted with
loaded throughout the lift. With only 200mm clearance to work with, the Larsen & Toubro team lifted and placed the dome into position on top of the inner containment wall in just two hours, with alignment and anchoring taking a further three hours, after which the crane was released.
Larsen & Toubro commented “During test runs the turnbuckles where rotated according to the load displayed on all 18 load shackles to distribute the loads equally. This test was demonstrated to our client and the regulatory board, who were then happy to give their permission to lift the dome on the very next day.”
a 55te wireless load shackle. At the customers request, a Crosby G2130 was used, rather than the smaller standard TELSHACK-B 55te, as it afforded a better fit within the lifting lugs.
LCM Systems also supplied a telemetry base station that detected the telemetry signals from the load shackles and transmitted them to a laptop, where engineers were able to view the loads on each lifting lug to ensure they remained uniformly loaded throughout the lift. With only 200mm clearance to work with, the Larsen & Toubro team lifted and placed the dome into position on top of the inner containment wall in just two hours, with alignment and anchoring taking a further three hours, after which the crane was released.

This test was demonstrated to our client and the regulatory board, who were then happy to give their permission to lift the dome on the very next day.”
For this project, we were contacted by a manufacturer of diving equipment, who were interested in having custom design load pins manufactured that were suitable for use in a marine/offshore environment. Because they would be used in a lifting
application that involved personnel, the traceability requirements were high, with 3.1 material certificates and charpy testing required. These load pins were required to measure the loads applied to the handling systems of the diving bells. The diving bells
are lifted ready for deployment through a dedicated opening in the centre of the vessel called a moon pool, and are also recovered using the same lifting system. Next to the moon pool there are a series of vertical sheaves, which connect to the diving bell. The plan was to have load pins installed in these sheaves to determine the weight of the diving bell. This would ensure that there were no overload situations, which could potentially endanger the personnel inside.
Four load pins are installed per moon pool lifting system, each rated to 1000kN. Manufactured from stainless steel and with
environmental sealing to IP67 for suitability in a marine environment, the load pins feature an internal amplifier to provide 4-20mA output. This allows the load measurement data to be exported direct to the vessels PLC system, where the results can be displayed and monitored for safety purposes.
The load pins were designed, manufactured and delivered within the required time frame, and the customer was very happy with their performance. They have since gone on to place orders for several more systems.

China has a rapidly developing submarine cable system manufacturing industry which operates in a healthy competitive manner. Subsea cables can fall into several different system product streams including relatively standard products for long haul telecoms projects (the subject of this paper) and customised products for the Oil & Gas, Scientific Observation Systems, Defence applications and HV subsea cables. While much of the Telecoms product has been sold in the domestic market, Hengtong Marine has broken into the International Market by addressing client concerns over quality and now has a track record for deployed overseas systems. This has been achieved in part by completing an offshore cable system sea trial, which is a requirement of the cable system qualification to ITU-T G-976 & ITU-T G.972 standards. The requirement for a sea trial is a barrier which every cable system producer has to address to achieve international sales. Hengtong Marine is moving forward to promote and improve the image of “Global Quality from China”.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
