Data Classification for CyberSecurity System DesignRekaNext Capital

There is a lack of understanding of the need to have Data Classification before we design any Cyber Security Systems. Too many times, I have come across where engineers over secured the system and makes the system bloated and expensive to maintain.
Root cause of Magnetic Humming due to TransformerRekaNext Capital

In Audio Design in cassettes, magnetic head picks up magnetic stray fields and cause irritating humming background noise. The 3rd harmonic of 50 Hz gets amplified when the speaker resonance coincides.
This R&D report validates the root cause. The solution was to have a physcial distance, while the current produced units had a wire loop to create a 150Hz pickup coil to phase cancellation manually tuned at PCB.
The document reports on bridge vibration monitoring tests carried out by SysEng Pte Ltd. A monitoring system was installed on the Henderson Foot Bridge but the data was corrupted. Further tests were conducted with 4 people simulating different loading conditions on the bridge such as jumping, walking, jogging, and groups crossing. Acceleration and displacement were measured in the X and Z axes. Analysis showed the Z axis was most sensitive, with peak acceleration around 1.6 Hz under all test conditions.
Assessment of the dynamic characteristics of the Helix Bridge at Marina Bay, ...RekaNext Capital

Modal testing was carried out to determine
the dynamic properties of the bridge. SysEng
(Singapore) Pte Ltd was commissioned
to undertake the modal testing. Professor James Brownjohn from Full Scale Dynamics Ltd was engaged by SysEng as a technical adviser for the modal testing.
Vibration tests were conducted on a slab in a building to measure Z-axis vibrations under different conditions. Tests measured ambient vibrations and vibrations with 1 or 5 people walking or running. Vibration levels were compared to ISO standards for human comfort over 8 hours. Test results from two locations on the slab showed vibrations were below the reduced ISO comfort limits when extrapolated to 8 hours. Therefore, the slab meets sensitivity standards for residential and office environments.
Vibration tests were conducted on a test slab to measure ambient vibration levels and vibration levels under different conditions, including people walking and running on the slab. Vibration levels were measured using an accelerometer and compared to ISO standards for human comfort. Test results found vibration levels were below the ISO limits for an 8 hour exposure at frequencies up to 100Hz, with the main resonant frequency of the slab being 13Hz. Therefore, the slab was found to meet ISO standards for human comfort.
1. Vibrating wire strain gages and load cells sometimes report different readings when monitoring the load on structural elements like struts during construction.
2. Vibrating wire strain gages measure localized strain, while load cells measure total load applied, which can lead to differences, especially at low load levels where sensitivity is critical.
3. Other factors like welding and electromagnetic interference during construction can also cause errors in vibrating wire strain gage readings but not affect load cells. Under ideal single loading conditions without bracing, readings may correlate better.
The document discusses a machine-to-machine (M2M) monitoring system called the eMonitoring system (eMs) that was developed to continuously monitor construction sites in a cost-effective way. The eMs connects sensors to detect structural movements and sends the data via GPRS to a central server. If sensor readings exceed preset thresholds, SMS alerts are automatically sent within 60 seconds. This allows potential site failures to be identified early and avoided. The eMs was successfully used to monitor strut forces during a tunnel construction project in Singapore.
Learned how to convert R&D results into a working Prototype. The PhD program was supported by a U.K. SME Industrial Scholarship from Wolf Safety Lamp Co, Sheffield to develop a Portable High Speed Turbo Generator from 55 Watts to 250 Watts within the same packaging. Starting from magnetic materials of Alnico until Rare Earth Samarium Cobalt with different Rotor Design configurations at TRL3. This project was to develop a full scale TRL5 prototype suitable for the product development launch of the Turbolite Model. The design required the development of an Efficient Electric Power Generator Model, a 2 Dimensional Magnetic Field Finite Element Method (FEM) Model from Maxwell' s Equation with Numerical Methods using Fortran IV and Development of over speed protection electronic techniques. The project was successful launched into a full scale product model by the company. In their website, it is mentioned that that product help the company to grow into an international business.

The document discusses sensors used for autonomous vehicles, including lidar. It notes that typical autonomous vehicles use multiple sensors, including 6 lidar sensors for 360 degree detection. Lidar is used for localization, 3D mapping, object detection and tracking. The document discusses testing sensor performance both individually and within the full autonomous vehicle system to measure latency and determine how to reduce braking reaction times to allow for higher traveling speeds. Further testing is proposed under different environmental conditions like rain to evaluate sensor and computer vision module performances.

A bedroom is more than just a place to sleep; it's where you find comfort and a sense of peace. It's the room that feels like a hug after a busy day. The bed, soft and inviting, is where you can sink into relaxation, with pillows that cradle your head and blankets that make you feel cozy and safe. It's a place where you can let go of the world and just be.
You might have a dresser or a closet, a place to tuck away clothes and personal items, but it’s also where you keep the little things that make you feel at home—like a favorite book on the nightstand or a candle that smells like calm. Soft lighting adds warmth, and windows let in just enough natural light during the day to keep things bright but not too harsh.
Decor adds that personal touch—whether it’s a plant in the corner, art on the walls, or a rug that feels nice underfoot. It’s where you can get away from everything, to recharge or reflect, and to make the space feel completely yours. A bedroom is the ultimate safe haven, designed for comfort, rest, and a sense of belonging.
Golf is a game of precision, patience, and sometimes, pure frustration. Every golfer knows the feeling of standing over a crucial putt, heart pounding, hoping not to miss. If you’ve ever felt the weight of a make-or-break moment on the green, the "If I Miss This Putt I'll Kill Myself" Hat is the perfect accessory for you.
