Raventech & University of North West presentation - emperors - 9 nov 2016-...John M Riggs
Naf-Tech combustion enhancer is a South-African product. Naf-Tech is a proprietary mixture of hydrocarbons that reduces the surface tension of the fuel when activated. Targeted activation ensures that Naf-Tech will not alter the distinct characteristics of the base fuel before the physical injection of the fuel takes place.
Naf-Tech improves fuel vaporisation during injection thereby increasing the burn velocity of the fuel transforming more of the fuel’s potential energy into mechanical energy. Naf-Tech is widely used in various applications such as transport, mining, earthmoving, diesel generators and shipping.
Naf-Tech is used by a number of companies, some of which are listed on the JSE. The majority of these companies have been using Naf-Tech for several years and have also concluded successful R&D programs using Naf-Tech.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

3. Background
• US mining industry consumes approx. 365
billion kWh of energy/yr.
• US DOE estimates that energy consumption
can be reduced by 49% by using current best
practice and with more research.
• This translates into nearly $3.7 billion of
potential savings at 5.3¢/kWh of energy.
4. Background
• Current energy-saving
strategies in mining
tend to involve
technology
improvements (e.g.
improving engine
performance).
• However, there is evidence that operator
practices and mine operating conditions
significantly affect the energy consumption.

7. Solution Methodology
• Discrete event simulation chosen as
the solution approach
• Arena®, based on SIMAN, used in this
study

8. System Specification
• Fragmented overburden is removed by carry dozers with
truck-shovel removal for the last ~15 ft.
• One Hitachi EX1900 hydraulic shovel (14.4 yd3 dipper) and
two CAT® 785C (150-ton), rigid frame, haul trucks
• The mine also owned two CAT® 777 (100-ton) trucks, which
are used on long hauls
• Typical haul length is ~4,000 ft (3,960 ft surveyed) at designed
grade of 10%
• The mine runs two 11-hour shifts per day
• The shovel and trucks had on-board data logging systems that
were used to collect data.
• Shovel cycle times were obtained using time and motion
studies. 8

14. Experimentation & Analysis
• The model was used to
evaluate two scenarios after
discussions with
management
• Scenario 1: Additional CAT
777 trucks
– Payload of 777 truck
described with 94 tons mean
• Scenario 2: Using EX2500 shovel instead of EX1900
– EX2500’s dipper is 20.4 yd3 and was assumed to load 777
and 785 in 4 and 5 passes, respectively.
– Same shovel cycle times and truck payloads assumed (fill
14
factors remain the same)
19. Conclusions
• A valid discrete event simulation model of truck-shovel
operations to evaluate energy efficiency has been built and
validated using Arena®
• The results show that using a larger excavator increases the
fuel efficiency of the operation while optimizing truck-shovel
matching does not
• Using a larger shovel, without adding additional trucks, will
lead to under-utilization of the shovel
• It is recommended that the mine add one CAT® 777 truck to
the two 785 trucks with the existing Hitachi EX1900 shovel –
this is expected to increase the production/shift by 4,400 tons
with approx. the same fuel efficiency.
