The document presents a generic architecture for an area-efficient 4-input binary coded decimal (BCD) adder implemented on an FPGA. It modifies a previously proposed area-efficient 3-input decimal adder to support a generic number of inputs. The proposed 4-input adder has four stages: 1) carry save addition and propagation/generation signal generation, 2) carry network, 3) correction stage, and 4) final addition. Simulation results on a Xilinx FPGA for different number of bits and inputs are presented, showing the adder has reduced delay and area compared to previous approaches. The generic approach can support addition of any number of inputs.
This document summarizes research on human motion tracking techniques using skeleton models. It discusses how model-based approaches use a predefined human skeleton model to represent joints and segments. Video-based approaches can infer physical attributes and daily actions without sensors. The document reviews several papers on reconstructing 3D human pose from video, using reduced joint sets and shape models to filter noise and track landmarks, and developing multi-view pose tracking using generative sampling and physical constraints. It also discusses challenges like high degrees of freedom and self-occlusion, and the need for efficient algorithms to enable real-time 3D full-body motion tracking from multiple cameras.
The document provides 10 reasons why students should not write their master's dissertation on sexual violence in war. It discusses how focusing solely on this topic can narrow political focus, inspire voyeurism in researching trauma, invoke colonial stereotypes, provide an insufficient historical account, ignore ethical dilemmas, neglect perspectives and positionality, encourage singular narratives that reinforce binaries, promote a non-feminist standpoint, inspire problematic proximity or distance, and result in replication rather than new insights. It encourages focusing studies on broader topics of gender, violence and militarism instead of continually reproducing analyses of sexual violence in war.
This document summarizes a research paper on identifying factors related to the adoption of green manufacturing practices among small and medium enterprises (SMEs) in India. It discusses how analytic hierarchy process was used to validate scales for measuring identified factors. The research established that green manufacturing relates to green product design, raw materials, processes, technology, packaging and packaging design. It also reviews prior literature on green manufacturing, identifying gaps such as a lack of empirical studies conducted in India.
This document describes a microcontroller-based gas flow alert system for an industrial furnace. The system monitors the furnace's gas flow mode (manual vs automatic) and uses a GSM modem to send alert messages if the mode is not changed on schedule. This helps reduce wasted nitrogen gas flow and lower production costs by ensuring the optimal gas flow level is maintained based on whether items are actively being loaded into the furnace. The system was designed and assembled with a microcontroller board connected to a GSM modem. It provides alerts if the operator fails to change the furnace mode between shifts, allowing nitrogen usage and costs to be reduced by an estimated Rs. 10,407.93 per month.

This document summarizes and compares different channel estimation techniques for OFDM systems. It discusses block-type pilot arrangement where pilots are sent on all subcarriers periodically, and comb-type pilot arrangement where pilots are spaced between data symbols. For block-type, channel estimation can be done with LS or MMSE. For comb-type, estimation is done at pilot frequencies using LS, MMSE or LMS, and interpolation between pilots with techniques like linear, cubic spline. Decision feedback equalizer is also implemented for block-type. Performance is evaluated using modulation schemes like QPSK, 16QAM under fading channels, and comb-type is shown to track fast fading better than block-type.

This document describes a Multilevel Relationship Algorithm (MRA) for improving association rule mining. MRA works in three stages: 1) It uses an Apriori algorithm to find level 1 associations between items within individual shops. 2) It uses the level 1 associations to find frequent itemsets across shops. 3) It uses Bayesian probability to determine dependencies between items across shops and generate learning rules. The algorithm aims to discover relationships between sales data from different shops to gain insights for business decisions.
This document summarizes a research paper on an electronic headlamp glare management system for automobiles. It discusses how the high beams of oncoming vehicles can blind other drivers, decreasing visibility and safety. Current systems require manual dimming of headlights, which is not always done properly. The described system senses when an oncoming vehicle is near and automatically dims the headlights to reduce glare without driver input. It aims to improve nighttime safety by eliminating the human error of forgetting or delaying to manually switch between high and low beams. The system construction, working principles, advantages, and potential applications in automobiles are analyzed in detail in the full paper.

This document proposes and evaluates methods for fusing 3D ear and face biometrics at the score level and feature level for personal authentication. Local 3D features are extracted from ear and face data and fused using root mean square distance matching at the feature level. At the score level, matching scores from ear and face modalities are fused using weighted sum rule techniques. Experiments on a database of 990 ear and face images from 60 individuals show that the multimodal biometrics systems using feature level or score level fusion techniques have lower equal error rates compared to unimodal ear or face systems alone, demonstrating improved performance from fusing the biometric modalities.
This document describes an experimental study of heat transfer in a rectangular duct with and without internal V-shaped ribs. Experiments were conducted with air flow in turbulent regime (Reynolds numbers 3000-18000) in smooth duct and ducts with continuous or discrete internal V-shaped ribs. Temperature and pressure measurements were taken to determine heat transfer coefficients and friction factors for different configurations. Results showed that continuous ribs enhanced heat transfer more than discrete ribs, but also increased pressure drop more substantially. Heat transfer enhancement was dependent on rib geometry and position.
This document summarizes a journal article about a traffic light control system using radio frequency (RF) for emergency vehicles. The system uses an RF transmitter in emergency vehicles that sends a signal to an RF receiver at an intersection. When the receiver gets the emergency signal, it overrides the normal traffic light sequence and changes the light for the emergency vehicle to green for a set time. This allows emergency vehicles to pass through intersections more quickly. The system was tested up to a range of 20 meters outdoors and 30 meters indoors using a 434MHz RF module and PIC microcontroller. The system aims to help reduce accidents by giving emergency vehicles priority at traffic lights.
