·   INTRODUCTION: Tool faults have attracted research interest. Tool wear is affected by several factors which influence monitoring cutting tools to track defects and avoid them. Several approaches are considered like ‘Online/Indirect’, where acquisition of parameters like Cutting Speed, Tool Temperature, Feed Rate, Forces, using suitable Transducers & ‘Off-line/ Direct’, where vision-based techniques like Laser Scatter Pattern, Scanning Electron Microscopy are seen. The online approach is suitable for knowledge-based ML learning schemes. Several investigations related to the study of Vibration Signals to review Tool Health were given. ·   METHODOLOGY: The diagram shows the methodology used; the tool conditions were categorized using 6 algorithms which are: 1.      Decision tree (J48) classifier-  A decision tree serves as an efficient tool in the domain of judgmental investigation. It is a special algorithm that performs a dual role i.e. while con...

                 The eagle has the longest lifespan among birds. Eagles usually live between 20-30 years in the wild. As apex predators, they live longer than most other birds. The oldest wild eagle in history is about 32 years of age. It can live up to 70 years. But to reach this point, the eagle has to make a difficult decision. By the ‘40s its long, flexible talons can no longer hold prey for food.               Talons are hard, sharp, and curved throughout the life of the eagle. The talons and the beak are made out of keratin, the same material as our fingernails. Think about how long it takes for your nails to grow.               An eagle’s beak is hooked so that it can rip and tear its food. It has this distinctive hooked beak throughout its life, like all birds of prey. Beak and talons are important for an eagle’s ability to catch and consume food. No ...

  Pallava Dynasty                                                The Pallava Dynasty rose to Prominence in South India from early 4th century to Late 9th century. Their Origins were said to be from the subordinates of  Satavahana Dynasty in the Deccan, They made Kanchipuram in Tamil Nadu as their capital .They were able to consolidate their power for around 500 years!! Pallava Kings were great Patrons of Culture, Art, Architecture and Literature. They Built great cities such as Kanchi, Mahabalipuram etc, Centers of Learnings ,Temples such as Kailasnathar Temple in Kanchipuram and Shore Temple in Mahabalipuram . Pallavas had a Great influence in the South Asia From Ceylon to Indonesia, Malay Peninsula and Cambodia. Their Territory extended from northern part of Andhra Pradesh to Kaveri River in the South during the peak of the empire. It was Pallavas under who...

  Nanomaterials in your cloths Nanomaterials have wide variety of applications especially in textiles. It is used in the manufacturing of protective garments for workers involved in emergency services such as military personnel, firefighters and medical workers. Nanoparticles can be incorporated into the fibers or they can be applied as a coating on the surface of a finished product. These techniques can enhance durability and are also capable of making the fabric resistant to extreme weather conditions. In Medical field, it is used for drug delivery and wound healing. silver nanoparticles are used in products related to dressings for burns and scald. fabrics that are lightweight, having high degree of resistance to extreme temperatures, durable, antibacterial activity, water-resistant, Such characteristics are ideal for military usage. Such a fibre can be produced using nanoparticles. Nanotechnology can also be used to chemically target and eliminate odor-causing molecules. the si...

    TinyML focuses on optimizing machine learning (ML) workloads for processing on microcontrollers as small as a grain of rice and utilizing only a few milliwatts of electricity. TinyML provides intelligence to little devices. We mean minuscule in every sense of the word: as small as a grain of rice and requires very little energy. TinyML, which has the support of Arm, Google, Qualcomm, and others, has the potential to transform the Internet of Things (IoT), where billions of tiny devices based on Arm chips are already being used to provide greater insight and efficiency in consumer, medical, automotive, and industrial sectors. Why target microcontrollers with TinyML? Microcontrollers such as the Arm Cortex-M family are an ideal platform for ML because they’re already used everywhere. They perform real-time calculations quickly and efficiently, so they’re reliable and responsive, and because they use very little power, can be deployed in places where replacing the battery is ...
