This document compares three technologies for producing tomato powder: spray drying, hot air convective dehydration with milling, and refractance window drying. Spray drying is not recommended due to the complex drying mechanisms of tomato components and the high energy consumption of the process. Convective drying in a tunnel dryer is a viable option, with countercurrent flow found to produce an acceptable product. Refractance window drying is a novel low-cost technology that allows infrared heating at low temperatures, minimizing heat damage to nutrients and flavors. Experimental results found refractance window drying of tomato pulp produced acceptable quality powder.
A Review on Recent Advances of Packaging in Food IndustryPriyankaKilaniya
Effective food packaging provides number of purposes. It functions as a container to hold and transport the food product, as well as a barrier to protect the food from outside contamination such as water, light, odours, bacteria, dust, and mechanical damage by maintaining the food quality. The package may also include barriers to keep the product's moisture content or gas composition consistent. Furthermore, convenience is vital role in packaging, and the desire for quick opening, dispensing, and resealing packages that maintain product quality until fully consumed is increasing. To facilitate trading, encourage sales, and inform on content and nutritional attributes, the packaging must be communicative. For storage of food there is huge scope for modified atmosphere packaging, intelligent packaging, active packaging, and controlled atmosphere packaging. Active packaging has a variety of uses, including carbon dioxide absorbers and emitters, oxygen scavengers, antimicrobials, and moisture control agents. Smart packaging is another term for intelligent packaging. Edible packaging, self-cooling and self-heating packaging, micro packaging, and water-soluble packaging are some of the advancements in package material.
environmental impact evaluation of the industry of panela by life cycle analysisIJEAB
The objective of the study is to evaluate the environmental impacts generated by the industry of the panela in Ecuador, using the Life Cycle Analysis methodology. The in situ information gathered allowed the identification of the sensitive environmental factors that are affected in all the operations that are carried out in the agroindustry of panela.

Environmental policy implications of packaging waste disposal practices in Ni...Premier Publishers
The study was conducted to assess the practices and technologies of disposing packaging wastes generated within and outside food processing firms. Data were collected using a structured questionnaire that was administered to 40 randomly selected food processing firms in Oyo and Lagos State of Nigeria. Data were also collected through key formant interview and participant observation. Data obtained were analysed using the Statistical Package for the Social Sciences (SPSS) version 16. Results showed that packaging materials of various types, design and volume were used by the firms studied, most of which get accumulated in the municipality due to eat and throw habit of the users. More than 62% of the firms used polyethylene/plastic packaging materials which have high implication for environmental pollution. A minimal percentage of between 1-5% of the packaging materials used became waste at the end of the production processes. In selecting packaging materials, product attractiveness ranked highest (4.05 ± 0.29) with little consideration for package disposal, biological degradability and environmental consideration. A large number of the food firms (94.6%) manage wastes generated within their premises mostly through burning / bury and are not responsible for waste generated by their products in the municipality.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate

Accident detection system project report.pdfKamal Acharya
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.
