Design is as good (or flawed) as the people who make itKayla J Heffernan
Talk given at UX Australia 2016 held in Melbourne.
ABOUT THE TALK:
No one sets out to intentionally design a system that is hard to use for - or worse, excludes or discriminates against - some users. Designers are trying their best. You're probably a good person, but a human nonetheless, therefore not perfect. Design can only be as good as the people who make it. Conversely, design is as flawed as the people who make it.
ABOUT THE SPEAKER:
Kayla Heffernan is a user and experiencer of products, frustrated with mediocrity and a passionate advocate for the voice of all users. Kayla is a UX designer at SEEK and also undertaking a PhD in Interaction Design looking at digital insertables. In her spare time… she doesn’t have any.

This is the Logic circuit which enables taking the MW data from the consumers to the substation, separating them into two major categories: a fixed cost for any 4 loads, and cost will increment from 5th load onwards.

In-silico study of ToxCast GPCR assays by quantitative structure-activity rel...Kamel Mansouri
The EPA tested several thousand chemicals in 700 toxicity-related in-vitro HTS bioassays through the ToxCast and Tox21 projects. However, the chemical space of interest for environmental exposure is much wider than this set of chemicals. Thus, there is a need to fill data gaps with in-silico methods, and quantitative structure-activity relationships (QSARs) are a cost effective approach to predict biological activity. The overall goal of this project was to use QSAR predictions to fill the data gaps in a larger environmental database of ~30K structures. The specific aim of the current work was to build QSAR models for multiple ToxCast assays using a subset of 1800 chemicals tested in 18 G-Protein Coupled Receptor (GPCR) assays. These assays are part of the aminergic category which was among the most active within the biochemical assays. Using PLSDA for the human histamine H1 GPCR assay, the classification accuracy reached 94% with a non-error rate of 89% in fitting and 80% in 5-fold CV, with only 2 latent variables. These results demonstrate the ability of QSAR models to predict bioactivity.
Not Dead Yet: Designing Great Experiences with Bad DataSonia Koesterer
By Sonia Koesterer
The world is imperfect. Every “happy path” intersects with dozens of crappy paths caused by typos, technical errors, and data that goes missing, is mis-assigned, adulterated, or is otherwise compromised/ stolen by evil data pirates. While you can’t prevent all data fails, you can avoid catastrophic failures, design graceful recoveries, and even turn the weakest points of your service into a strategic advantage. In short, you can create great services despite bad data.
The impact of data failure can be a humorous accident, minor inconvenience, or completely detrimental. For example, each year, the U.S. government falsely declares over 12,000 people dead due mostly to typos. In sheer percentage this is a rarity of a corner case of an edge case… but for those 12,000 individuals who suddenly lose their social security benefits, health insurance, bank accounts, and can’t easily prove they are alive, it’s catastrophic.
So design for the the edge-case! Understand the weakest points of your service, learn from them, and turn your failures into great experiences.

AWS Simple Workflow: Distributed Out of the Box! - Morning@LohikaSerhiy Batyuk
Do you have a lot of complex jobs that you need to run as part of your application? Do they consist of multiple tasks and you wonder how to orchestrate them properly? Do you want to be able to easily scale their execution? Is availability of your workers important to you? If you answer “Yes” to these questions then AWS Simple Workflow is the right tool for you.
In this talk we will go through Amazon SWF and Java Flow Framework and you will see how to get a distributed job execution engine right out of the box. We will also compare SWF to alternative solutions, discuss real life experience, and of course enjoy a live demo.
The talk will be most useful to everyone who is interested in the design of distributed systems and is new to AWS SWF.
Overview of the fundamental roles in Hydropower generation and the components involved in wider Electrical Engineering.
This paper presents the design and construction of hydroelectric dams from the hydrologist’s survey of the valley before construction, all aspects and involved disciplines, fluid dynamics, structural engineering, generation and mains frequency regulation to the very transmission of power through the network in the United Kingdom.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
