The document discusses design patterns and provides examples of several common patterns including abstraction-occurrence, general hierarchy, player-role, singleton, observer, delegation, adapter, and facade patterns. For each pattern, the context, problem, forces, solution, and examples are described. Design patterns provide reusable solutions to commonly occurring problems in software design and allow developers to learn from prior experience.
Design patterns are optimized, reusable solutions to the programming problems that we encounter every day. A design pattern is not a class or a library that we can simply plug into our system; it's much more than that. It is a template that has to be implemented in the correct situation. It's not language-specific either. A good design pattern should be implementable in most—if not all—languages, depending on the capabilities of the language. Most importantly, any design pattern can be a double-edged sword— if implemented in the wrong place, it can be disastrous and create many problems for you. However, implemented in the right place, at the right time, it can be your savior.

Hönnunarmunstur er þekktar og reyndar lausnir við almennum vandamálum. Hugbúnaðargerð felur í sér að leysa vandamál og oft rekumst við að sömu vandamálin aftur og aftur. Þessi vandamál má leysa með þekktum leiðum, svo kölluðum munstrum. Hönnunarmunstur skjala þekktar lausnir. Þau eru byggð á þekkingu úr iðnaðnum, segja hvað virkar og af hverju.
Í þessum fyrirlestri skoðum við hönnunarmunstur, sögu þeirra og hvernig þau eru skjöluð. Við lítum á ýmis dæmi og tökum svo fyrir grunnmunstur - base patterns. Þá skoðum við Open Close Principle sem er eitt af þessum prinsippum sem við þurfum að hafa í huga.
The presentation consist of following:
- pimpl Idiom
- Introduction to ABC software firm – Rahul’s story.
- The SOLID Principles
- Outline of other principles : KISS , DRY , YAGNI.
- The story of a Paper- Boy : Law of Demeter
The maze of Design Patterns & SOLID PrinciplesMuhammad Raza
There are several mistakes usually developers make during product development. So keeping your demand of how to optimize time and resources so that there should be the least scope of errors and bugs we brought a demanding topic for you. This talk will cover the best practices that should be involved in web development and if you are adopting them your code will project you more experienced than an experienced developer.
Design patterns are known and tested solutions to common problem. In software engineering we constantly come across similar problems. The same problems or tasks need to be programmed again and again, hence patterns. Design patterns catalog and document these solutions.They are built on industry knowledge of what works and why. We will look at what design patterns are, their history and the structure of documenting patterns.
As an example we look at the Observer pattern.
We will also look at Liskov Substitution Principle and the Open Close Principle, both which are very useful in building enterprise systems. Finally we look at creating objects.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.

Understanding Inductive Bias in Machine LearningSUTEJAS
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.
We have compiled the most important slides from each speaker's presentation. This year’s compilation, available for free, captures the key insights and contributions shared during the DfMAy 2024 conference.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
