Energy efficiency improvement and energy saving are major industrial concerns now-a-days. This paper mainly aims at focusing key issues for reducing energy wastage and subsequent reduction of excessive energy consumption due to inefficient machinery and unplanned electrical system. In order to improve the energy consumption pattern, particularly jute processing industry of Bangladesh is considered as case study; several energy saving scopes and way of improvement have been identified. The objective is to addresses utilization strategy through mathematical analysis to maximize machine efficiency leads to greater production, financial profit by reduction of energy bill as well as trapping carbon emission. In addition, to attain the target of improving energy efficiency of Bangladesh Government’s Sustainable Development Goal (SDG), this strategy can contribute by decarbonizing industrial operation and supply chains thorough improved energy efficiency. Also tend to reduce the carbon footprint of jute products, services and processes. This leads to setting ambitious emissions reductions targets in line with development of green industry; also scaling up potential investment scope as Clean Development Mechanism (CDM) projects in the development of innovative low-carbon products and services.

Crack is one of the measure catastrophic failure in mechanical machines so it’s necessary to detect it in early stage. In this paper proposed a method to identify crack in early stage. The purpose of this study is to describe relation between modal natural frequencies change due to crack in shaft with respective crack parameters like Depth, Location and Width. Analysis is done for Single Crack and is evaluated. Analysis reveals how modal natural frequency decreases with change in crack size. It has been observed that when shaft suffers from a crack or any damage then its dynamic properties changes. Crack causes a reduction in stiffness and ultimately reduction in its modal natural frequencies which leads to change in dynamic response of the shaft. The results of modal analysis using FEA are validated with experimental modal analysis.

IP filtering is a technique used to control IP packets flow in and out of a network where Filter engine inspects at source and destination IP of incoming and outgoing packets. Here Filter engine is designed to improve the performance of the filter, i.e. to reduce the processing time of the filtering mechanism. The data structure used in the IP filter is hashing, for larger number of hosts and various ranges IP network of hosts hashing provides much better performance than link list. Here hash function for the hash table is valid IP ranges. In hash table technique the comparison can be done with minimum number of comparisons.

In this study the author analyzed the effects of sewing thread count on seam strength. In this study different types of seam classes (Superimposed Seam, Lapped Seam & Bound Seam) were produced by using different sewing thread counts (Tex-27, Tex-60, Tex-80 & Tex-120) and Stitch Class-300 (Lock Stitch) was used to produce the seams keeping the Stitch Per Inch at 4.5. Here seam strengths of different seams were determined by using Titan Universal Strength Tester and ASTM D1683-04 method was used to determine seam strengths. After completing the research work, it was found that seam strength increased with the increment of sewing thread count for same seam class. But the suitability of the sewing thread countchanged with the variation in thread size whendifferent seam classescame into account.

The purpose of this observational work is to produce an innovative engineered technique in vegetable market waste management.Even though many treatment methods were currently adopted in treating the organic green waste (composting, land fill, vermicomposting etc.,) but vermicomposting is highly commended, since it converts the green waste into enriched nutrient manure with less operational cost.The trouble with the vermicomposting process is, it consumes more time.And very particular, when it comes to vermicomposting, the waste should be pre-composted for two weeks (depends on the nature of waste) before they fed to worms to avoid the impact load on worms (Ndegwa and Thompson, 1999).This work focuses on getting rid of the pre-composting process in vermicomposting, by carrying the green waste and feed the stocked waste to vermi at the needed time.This will shorten the time expelled in the process and high percent of intensity reduction of waste will be attained. The findings from the current study show the high feasibility of using the modified vermicomposting process because of the following reasons; (i) high volume reduction of waste in short duration. (ii) The stocked waste can be utilized at any time for vermicomposting (iii) 40%-time difference was recorded in the modified vermicomposting process than the formal one.
