Sample Network Analysis Report based on Wireshark Analysis
This network analysis report examines a packet capture file containing traffic between two internal hosts downloading a file from a remote server. The analysis found that one internal host, with IP ending in 1.119, experienced significant packet loss during the download, as shown by drops in throughput and bursts of TCP errors. This packet loss indicates a potential failure at an infrastructure device, likely causing the observed retransmissions and degradation in performance. Further analysis of ingress traffic is needed to determine if the packet loss is occurring internally or externally to the network.

Packet Analysis - Course Technology Computing Conference
Packet Analysis - Course Technology Computing Conference
Presenter: Lisa Bock - Pennsylvania College of Technology
Most network administrators are well-versed in hardware, applications, operating systems, and network analysis tools. However, many are not trained in analyzing network traffic. Network administrators should be able to identify normal network traffic in order to determine unusual or suspicious activity. Network packet analysis is important in order to troubleshoot congestion issues, create firewall and intrusion detection system rules, and perform incident and threat detection. This hands-on presentation will review fundamental concepts necessary to analyze network traffic, beginning with an overview of network analysis, then a review the TCP/IP protocol suite and LAN operations. Participants will examine packet captures and understand the field values of the protocols and as to what is considered normal behavior, and then examine captures that show exploits, network reconnaissance, and signatures of common network attacks. The program will use Wireshark, a network protocol analyzer for Unix and Windows, to study network packets, look at basic features such as display and capture filters, and examine common protocols such as TCP, HTTP, DNS, and FTP. Time permitting, the presentation will provide suggestions on how to troubleshoot performance problems, conduct a network baseline, and how to follow a TCP or UDP stream and see HTTP artifacts. Participants should have a basic knowledge of computer networking and an interest in the subject.

INVESTIGATING THE USE OF IMPEDANCE PLETHYSMOGRAPHY FOR DETECTING DECREASED BL...
Literature Review
According to Isabel Morales’ research, the foot impedance plethysmography was carried out with two distinct kinds of electrodes, using 1mA/10kHz and finding the impedance of the foot.
In this study Piuzzi research is an ultimate technique selected that makes use of a current with a frequency of 50 kHz that is injected into the thorax of the subject using a couple of textile electrodes.
In this study of Ramkumar & Babu, blood flow was performed using a fuzzy logic toolbox with many different activities, measured before and after the 25 seconds of breath-holding activity. The plethysmographic waveform of forearm impedance can be used to analyze the changes in a heartbeat that are correlated with the changes in heart stroke volume.
Contribution
In this work we are investigating using multiple electrodes to see the additional data going to make testing easier.
Our research is primarily focusing on the amount of blood flow through the finger of the upper limb for diabetic patients.
Conclusion
The finger-simplified model was created in model geometry. A framework made up of five parts was used to build the finger. (i.e., skin, fat, artery, muscle, and bone)
The study includes COMSOL simulation results compared with experimental results to obtain the optimum parameters for this technique. The COMSOL simulation uses 4 electrodes in different positions with a current of 10mA giving the optimal frequency of 100Hz.
It was shown that multiple electrodes can be useful in obtaining impedance change.
This is useful because signals can not be obtained from one pair, or to further support the results.
The study was performed under normal resting conditions where an experimental procedure was set up to measure the impedance response from the finger.
Experiment results were not conclusive as more sensitive impedance analyzers are required.
This research will be helpful to find out the heartbeat using impedance plethysmography.

Fingerprint Recognition
Fingerprint Recognition
Fingerprint recognition is one of the oldest and most
researched fields of biometrics.
Some biological principles (Moenssens 1971) related
to fingerprint recognition are as follows:
Individual epidermal ridges and furrows have different characteristics for different fingerprints.
This forms the foundation of fingerprint recognition
The configuration types are individually variable; but they vary within limits that allow for a systematic classification.
Herein lies the basis for fingerprint classification.
The configuration and minute details of furrows are permanent and unchanging.

state space modeling of electrical system
Introduction
As systems become more complex, representing them with differential equations or transfer functions becomes cumbersome. This is even more true if the system has multiple inputs and outputs. This document introduces the state space method which largely alleviates this problem. The state space representation of a system replaces an nth order differential equation with a single first order matrix differential equation. The state space representation of a system is given by two equations :
The first equation is called the state equation, the second equation is called the output equation. For an nth order system (i.e., it can be represented by an nth order differential equation) with r inputs and m outputs the size of each of the matrices is as follows:
Several features: The state equation has a single first order derivative of the state vector on the left, and the state vector, q(t), and the input u(t) on the right. There are no derivatives on the right hand side. The output equation has the output on the left, and the state vector, q(t), and the input u(t) on the right. There are no derivatives on the right hand side.
q is nx1 (n rows by 1 column) q is called the state vector, it is a function of time A is nxn; A is the state matrix, a constant B is nxr; B is the input matrix, a constant u is rx1; u is the input, a function of time C is mxn; C is the output matrix, a constant D is mxr; D is the direct transition matrix, a constant y is mx1; y is the output, a function of time
Derivation of of State Space Model (Electrical)
To develop a state space system for an electrical system, they choosing the voltage across capacitors, and current through inductors as state variables. Recall that
so if we can write equations for the voltage across an inductor, it becomes a state equation when we divide by the inductance (i.e., if we have an equation for einductor and divide by L, it becomes an equation for diinductor/dt which is one of our state variable). Likewise if we can write an equation for the current through the capacitor and divide by the capacitance it becomes a state equation for ecapacitor
There are three energy storage elements, so we expect three state equations. Try choosing i1, i2 and e1 as state variables. Now we want equations for their derivatives. The voltage across the inductor L2 is e1 (which is one of our state variables) so our first state variable equation is
This equation has our input (ia) and two state variable (iL2 and iL1) and the current through the capacitor. So from this we can get our second state equation
Our third, and final, state equation we get by writing an equation for the voltage across L1 (which is e2) in terms of our other state variables

Applications of artificial Intelligence in Mechanical Engineering.pdf
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Optimizing Gradle Builds - Gradle DPE Tour Berlin 2024
Sinan from the Delivery Hero mobile infrastructure engineering team shares a deep dive into performance acceleration with Gradle build cache optimizations. Sinan shares their journey into solving complex build-cache problems that affect Gradle builds. By understanding the challenges and solutions found in our journey, we aim to demonstrate the possibilities for faster builds. The case study reveals how overlapping outputs and cache misconfigurations led to significant increases in build times, especially as the project scaled up with numerous modules using Paparazzi tests. The journey from diagnosing to defeating cache issues offers invaluable lessons on maintaining cache integrity without sacrificing functionality.
