An Approach to Improvement in Heat Flow of Continuously Variable Transmission(CVT)

Pradip Patil

This Continuous Variable Transmissions (CVTs) are one of the most widely used automatic transmissions in light vehicles, and yet CVT cooling remains a major problem when under high load and high torque conditions. CVTs operate at very high rpm which poses a threat under the OSHA criteria for 'Hazardous Energy Control' hence, rotating components shall be shielded. Guards shall protect against hazardous release of energy should rotating components fail. This further adds another layer to the problem i.e. CVT casing. The purpose of this research is to find an efficient way to cool a CVT, implementing various aspects of Fluid Mechanics, Heat Transfer and CAE. The basic design of the study includes a standard CVT with its casing and various modification, like fins, ducts and fans to give optimum results. The research tests and analyses the effectiveness of up to three different combinations using Computational Fluid Dynamics (CFD) software. The results would help understand and overcome the current limitations of a CVT and implement them efficiently in light-medium weight vehicles.

Speak to Arduino And Control it with Google Assistant

Nayan Karpe

The idea behind Google Assistantcontrolled Arduino is to control home devices and
in addition a gas sensor and a PIR sensor for
security purpose have been integrated. When it
comes to our house, this concept can be aptly
incorporated to make it smarter, safer and
automated. This IoT project focuses on building a
smart wireless home security system which sends
alerts to the owner by using Internet in case of any
trespass and raises an alarm optionally. Besides,
the same can also be utilized for home automation
by making use of the same set of sensors. Google
Assistant is an android device which can be availed
through anywhere.The voice commands for Google
Assistant have been added through IFTTT website.
The commands given through the Google assistant
are decoded and then sent to the microcontroller,
the microcontroller in turn controls the relays
connected to it. On the other hand, gas sensor and
PIR sensor intimate the user in case of gas leakage
and unexpected movement respectively.

Adjustable Radio Technology Using BPSK Modulation

L. Vamsikrishna Reddy Lingamdinne — 2021-05-25

This research paper proposes a technique called a radio gating, called an RF gating, which consists of a symbolic change of the active time radio (ATR) on the RF foreground. This technique is particularly suitable for adapting the receiver's energy consumption to performance requirements without changing its architecture. In the specific case of binary turn-key signalling, the effect of this method on the Bit Error Rate (BER) performance is studied (BPSK).In existing it Minimum shift keying signalling will used in RF Power gating technique, it will have, low efficiency, and more bit error rate. In this paper to modified the Minimum shift keying technique to Binary shift keying technique. Finally this work is implemented in VHDL, and synthesized with Xilinx FPGA Vertex-5, and shown the area, power and delay variations.
