Introduction

Tracking systems play a crucial role in modern transportation and logistics. They provide valuable insights into the location, status, and performance of pilots, trucks, aircraft, and other vehicles, as well as simplify their management and reinforce safety.

However, developing robust tracking systems presents a significant challenge because they need to work well under different conditions, including heavy loads.

In this article, we’ll investigate the creation of robust tracking systems by presenting two different ways and examples of building them. Each approach uses its own set of technologies suited to particular situations and needs.

Overview of Common Approaches to Building Tracking Systems

All modern tracking systems vary in terms of technology, scalability, and features, but they all share the common goal of providing accurate and trustworthy tracking capabilities.

Creating tracking systems involves managing various data sources, handling large data volumes in real-time, and ensuring reliability and performance. Here are some common ways to do it:

Real-Time Data Input

Tracking systems need to handle data as it comes in, ensuring no information gets lost or delayed. Technologies like Apache Kafka or AWS Kinesis help manage this continuous flow of data efficiently.

Data Storage and Management

Different tracking systems use different types of databases to store their information. Some rely on traditional databases like PostgreSQL or SQL Server for structured data, while others prefer NoSQL databases like Cassandra or MongoDB for their flexibility with unstructured data.

System Reliability

It’s crucial for tracking systems to stay operational even if certain components fail. Strategies like database replication and load balancing help ensure uninterrupted service and prevent disruptions in data collection and processing.

Scalability Demands

Tracking systems need to be able to handle instabilities in data volume and user activity. They must scale up during peak periods and scale down during quieter times to maintain optimal performance without overloading resources.

User Interface

Users need intuitive interfaces to access and interpret tracking data effectively. Building interfaces with Spring Boot or React helps create user-friendly experiences that simplify data visualization and analysis.

Deployment

Tracking systems can be deployed on various platforms, from cloud services like AWS or Google Cloud to in-house servers. Each option has its advantages and considerations, such as scalability, cost, and control over infrastructure.

Data Security

Since tracking systems deal with sensitive information, they must prioritize data security. Implementing measures like encryption and access controls helps protect data integrity and confidentiality, ensuring compliance with security regulations.

System Performance

Continuous monitoring of system performance is essential to detect and address issues promptly. Monitoring tools like Prometheus or Grafana provide insights into system health and performance metrics, enabling proactive maintenance and troubleshooting.

Approach 1: Java-Kafka-Cassandra

Solution Example: High-Load Multi-Tenant Tracking System

Technology Stack: Java, Kafka, Cassandra, PostgreSQL, ELK, Spring Boot

Approach Overview

The first approach is well-suited for building a high-frequency, multi-tenant tracking system resembling the operational complexity of an airport, encompassing various elements such as planes, service machinery like fuel tanks, buses, luggage carriers, and more.

By using technologies like Kafka, Cassandra, and Spring Boot, it ensures robustness, scalability, and performance while providing a user-friendly interface for data visualization and analysis.

Let’s break down how each aspect works.

Hadoop-Based Stack for Scalability

Using a Hadoop-based stack ensures scalability and prevents system overload, particularly in scenarios with a high frequency of tracking points. Hadoop’s distributed processing capabilities allow the system to handle large volumes of data without compromising performance.

Application Architecture

The application architecture comprises three main parts:

• A rich UI application built using Java and Spring Boot, providing features such as reports, analytics, and dashboards.
• PostgreSQL is used for structured data storage, facilitating data querying and retrieval.
• A load balancer is deployed in front of the application to evenly distribute incoming traffic across multiple instances, improving scalability and fault tolerance.

High-Frequency Data Processing with Kafka

Kafka is chosen as the primary data ingestion and processing tool due to its reliability and scalability, particularly for handling high-frequency data streams.

Basic data filtering mechanisms are applied on top of data consumption to manage the influx of data.

Once filtered, the data is streamed to Cassandra, a highly scalable NoSQL database, in a denormalized format. This approach optimizes querying performance and storage efficiency.

Schedule-Based Background Tasks

Scheduled tasks are implemented to collect data from Cassandra and transform it into a user-friendly format suitable for reporting and analysis. These tasks ensure regular updates and availability of data for consumption by the rich UI application, enhancing the overall user experience.

If we’ll go deeper, the scheme will look like this:

Verdict

In summary, building a tracking system using the Java-Kafka-Cassandra approach involves designing a scalable and fault-tolerant architecture capable of handling high-frequency data streams.

By applying technologies like Kafka for data processing and Cassandra for storage, coupled with a robust application architecture and scheduled background tasks, the system can efficiently manage tracking data while providing users with actionable insights through a user-friendly interface.

Approach 2: .NET-MS SQL-MongoDB

Solution Example: Truck Tracking System

Technology Stack: .NET, MS SQL, MongoDB, Windows Server, Linux (NGINX)

Approach Overview

Building a tracking system using the .NET, MS SQL, and MongoDB approach involves tailoring the system to track vehicles with less stringent requirements compared to previous solutions.

Here’s how the architecture and infrastructure work:

Microsoft-Specific Infrastructure

The infrastructure is Microsoft-specific, using technologies, such as Active Directory for user authentication and authorization.

Shared disks and network cards are utilized for the MS SQL Always-On cluster, providing high availability and fault tolerance.

The system employs two active nodes along with other components, adhering to standard MS monitoring practices.

VMWare vSphere Deployment

VMWare vSphere is used behind the scenes, deploying each element of the system as a separate virtual machine.

Windows Server is the preferred operating system for most components, except for MongoDB and NGINX, which run on Linux boxes.

Classic Cluster Architecture

The architecture resembles a classic cluster setup, devoid of modern Kubernetes or Dockerization.

Initially, there were no Linux boxes, but subsequent adjustments were made to address specific issues encountered post-launch.

Addressing Performance and Backup Issues

CPU consumption by LSAss due to HTTPS processing and unpredictable backup times for MongoDB were identified as key issues.

A separate VM with Linux and NGINX was launched to offload HTTPS traffic processing, mitigating CPU consumption.

To address backup issues, three MongoDB instances were implemented: one master and two slaves. When a backup is needed, one of the slave nodes detaches from the cluster, allowing for quick backups to be performed. The node is then reattached as a slave.

Verdict

This approach applies the .NET framework, MS SQL, and MongoDB to build a tracking system tailored with fewer requirements.

The Microsoft-specific infrastructure, VMWare vSphere deployment, and classic cluster architecture provide a reliable foundation for the system. Addressing performance and backup issues ensures the system operates efficiently and maintains data integrity.

Bottom Line

Both solutions offer robust tracking systems catering to different requirements and load scenarios.

Approach 1 uses a scalable, multi-tenant architecture with high-frequency data processing, while Approach 2 adopts a Microsoft-specific infrastructure with enhancements to address performance and backup challenges.

These architectures provide reliable tracking solutions for pilots and vehicles in diverse operational environments, ensuring scalability, reliability, and performance.

Microsoft Excel is a powerful tool used by millions of people worldwide for various purposes, including analyzing data, making reports, and planning finances.

While Excel already has a bunch of useful tools built in, its functionality can be further extended through extra features called add-ins, which can be ready-to-use or custom-made.

In this article, we’ll go over all the ins and outs of Excel add-in development, including the different types of extensions, the benefits of making your own, and the guide to creating personalized enhancements to improve your Microsoft Office experience.

Definition and Purpose of Excel Extensions

Excel extensions are extra tools you can plug into Excel to make it do more things than it initially could. It might include automating tasks, simplifying the existing functions, and much more.

Excel plugins have four main goals:

• Automation: Add-ins help you automate tasks you do over and over again, saving time and effort.
• Customization: They let you change Excel to fit how you work best, making things more comfortable and efficient for you.
• Enhanced Features: Enhancements give you new tools and features that regular Excel doesn’t have, so you can do more with your data and analysis.
• Integration: Plugins can work with other programs and data sources, making it easier to connect Excel with the other tools you use.

Types of Excel Extensions

Microsoft Office add-ins come in different types, each with its own purpose to make Excel work better for you. Here’s a breakdown of the main types you might come across:

Task Pane Plugins

Task pane versions appear in the form of additional toolbars that show up next to your Excel spreadsheet. They give you more options and features without getting in the way of your work. You can use them for making charts, filling out forms, getting data from different sources, and doing complex calculations.

Ribbon Enhancements

Ribbon types expand Excel’s top menu by adding new tabs or buttons. In simple terms, they blend right in with Excel’s regular menu, making it easy to find and use more tools. Ribbon types are especially convenient for quickly accessing the functions you use a lot or tweaking them to exactly fit your working style.

Content Modules

Content modules are special instruments you can put right into your Excel sheets. It provides different charts that you can play with, maps, forms, or anything else that makes it easier to perceive and work with your data.

Benefits of Creating and Using Custom Excel Solutions

Custom Excel solutions offer businesses great benefits compared to ready-made options.

One big advantage is customization. With bespoke extensions, companies can adjust features and interfaces to fit their exact needs. Off-the-shelf solutions, in turn, might not be as adaptable since they’re made to suit many different directions and firms.

Another plus of made-to-order Excel programs is how well they get along with other systems. Specialized supplements can easily connect with existing software and processes.

Off-the-shelf options, in turn, might offer integration too. But they might not fit perfectly with a company’s specific setup.

Scalability is another point that greatly adds to the benefits of customized solutions. Custom add-ins can grow and change along with a company. As a business expands, one-off solutions can be easily updated to meet new needs.

Ready-made solutions, on the other hand, might struggle to keep up because they’re made for a general audience.

When it comes to costs, bespoke add-ins can save money in the long run. While there might be many upfront investments for developing them, they can boost performance and cut down on manual work, leading to savings over time.

In contrast, off-the-shelf programs often come with subscription fees or licensing costs that can add up, especially if a company needs many extra features or support.

In short, individualized Excel programs give businesses a lot of benefits compared to pre-made ones.

They can be adjusted to fit a company’s exact needs, work well with other software, grow as the company does, save money in the long run, and provide better security and user experience.

Investing in personalized programs helps companies have Excel tools that work just right for them, making their work easier, more efficient, and more creative.

What Are Convolutional Neural Networks (CNNs)?

Convolutional Neural Networks (CNNs) are the workhorses of modern computer vision.

They mimic the human visual system and excel at spotting patterns in images and videos by using layers that scan images for things like edges, textures, and shapes (convolution) and then reduce the data size (pooling).

By stacking these layers, CNNs can learn to identify basic patterns like edges and work their way up to more complex ones like faces, objects, or even scenes.

Challenges with Pre-Trained Networks

While CNNs are powerful tools for feature extraction, their use is often accompanied by several challenges. Pre-trained networks, which are often used because they offer high-level features, need a lot of resources.

They demand significant memory and computational power, which makes them less practical for resource-constrained environments. Additionally, standard artificial neurons within CNNs may have trouble with certain kinds of data.

For instance, telling an edge apart from its color can be tough for regular CNNs. Plus, they can struggle with different lighting conditions, like recognizing people during the day but having a hard time at twilight.

Introducing Other Computer Vision Methods

To overcome the challenges and enhance pattern recognition further, it is vital to combine CNNs with other computer vision techniques.

The idea here is synergy. These complementary methods can address the limitations of CNNs while building upon their strengths, creating a powerful framework for pattern recognition.

Support Vector Machines (SVM)

SVMs, when combined with CNNs, give rise to novel architectures like Convolutional SVM (CSVM). These hybrids excel at processing smaller datasets, which can be invaluable when data is scarce, costly, or time-consuming to acquire.

Conditional Random Fields (CRFs)

CRFs, rooted in probabilistic graphical modeling, work in tandem with CNNs or Recurrent Neural Networks (RNNs) to achieve new heights in image segmentation tasks. This combination improves the precision of recognizing objects within images.

K-means Clustering

K-means clustering isn’t just for grouping data. When used in combination with CNNs, it can help these neural networks learn parameters, such as weights, more effectively. Additionally, combining various unsupervised CNN architectures with K-means clustering can improve feature representation.

Histogram of Oriented Gradients (HOG)

HOG provides an efficient way to extract features from images before training a custom CNN. This preprocessing step speeds up training and saves computational resources by focusing on the most informative aspects of the data.

Region-Based CNNs (R-CNNs)

R-CNNs do things differently. They start by spotting regions of interest (ROIs) in an image, which probably have objects. Then, they use a bunch of SVM classifiers to figure out what kind of object is there.

There are newer versions like Fast R-CNN, Faster R-CNN, Mask R-CNN, and Mesh R-CNN, which promise to make object recognition better.

New Approaches and Research Findings

Recent research in pattern recognition has introduced new and promising approaches in artificial intelligence and computer vision.

Convolutional Support Vector Machines (SVMs) have become a game-changer, especially for handling smaller datasets in applications with limited data.

Advances in Conditional Random Fields (CRFs) have improved semantic segmentation by combining pattern understanding with contextual awareness from CNNs, achieving top-notch results.

Unsupervised learning benefits from K-means clustering, improving features and reducing the need for large labeled datasets.

The use of the Histogram of Oriented Gradients (HOG) method as a preprocessing step has made training more efficient, particularly in real-time object recognition tasks.

Additionally, the evolution of Region-based CNNs (R-CNNs), including Fast R-CNN, Faster R-CNN, Mask R-CNN, and Mesh R-CNN, has transformed object detection and boosted AI capabilities across various fields.

These findings represent ongoing progress in pattern recognition, promising more precise, flexible, and efficient AI applications.

Benefits of Lightweight Architectures

Developing lightweight architectures is a promising avenue in pattern recognition. These streamlined networks reduce the computational demands, making them suitable for edge computing and resource-constrained environments.

The benefits include faster inference times and improved energy efficiency, making pattern recognition accessible to a wider range of applications.

Future Directions

The future of pattern recognition holds exciting possibilities. Emerging techniques and technologies promise to further enrich its capabilities.

We expect the development of more efficient neural network architectures, advanced unsupervised learning approaches, and sophisticated data preprocessing techniques.

These advancements will continue to drive progress in pattern recognition, offering even greater precision and efficiency.

When it comes to social justice, what role do brands play?

As conflict around the globe continues, marketers are put in a challenging position when it comes to making brand statements. It’s nearly impossible to make a perfectly neutral statement that will satisfy all points of view, which is what many brands try to do in an effort to avoid alienating potential customers.

Interestingly enough, consumer preferences on how involved brands should be in social justice movements are evolving in real time as world events unfold.

In 2021, 54% of American consumers expressed companies should take a stance on social issues. However, according to research by Gallup and Bentley University, some consumers are walking back that claim.

Per this year’s Business in Society Report, only 41% of Americans now believe brands should take a public stance on social causes. However, it’s important to note that the drop in interest in brand advocacy doesn’t ring true for all demographics. According to the Gallup and Bentley study:

• 53% of buyers between the ages of 18 and 29 believe brands should take a public stance on current issues (compared to 47% of buyers between 30 and 44, and 35% of consumers over 45)
• 44% of women believe brands should advocate for social issues compared to 38% of men
• Consumers who identify as Black or Asian (61% of both populations) want to see brands take a public stance
• 57% of consumers who identify as LGBTQ+ want brands to speak on social issues

This data suggests brand advocacy remains important to younger people and marginalized groups.

When it comes to social justice, what role do brands play?

Though a majority of consumers want to see brands refrain from making direct statements about social issues, companies are still seen as major agents of change.

According to Edelman’s 2023 Trust Barometer Report, global consumers now trust business more than government. Beyond speaking out about social issues, consumers are looking to companies to make tangible changes that would improve the quality of life for employees and surrounding communities through better distribution of wealth and more transparent sustainability practices.

Brands Navigating Pushback

Earlier this year, Bud Light and Target received pushback over their Pride month campaigns and activations, leaving some companies to scale back on Pride-related content. It’s likely that this trend will continue as the U.S. heads into a tense election year in 2024.

While brands making blanket statements and social media about social issues can be seen as performative, how brands should move forward with social and political statements should be done thoughtfully and carefully with the brand’s core values and target audience in mind.
