As genetically-encoded fluorescence indicators of calcium and membrane potential evolve and improve, optical methods advance to exploit their full potential for neurophysiology research. With so many choices, the neurophysiologist needs a systematic framework for comparing and predicting the performance of indicator/imaging system combinations. Dr. Foust will present such a framework for which the key figure of merit is the signal-to-noise ratio of the time-varying fluorescence signal. In this context I will also describe our efforts to boost photon budgets for membrane potential and calcium imaging with multi-focal two-photon and light-field imaging systems.

Human activity Recognition (HAR) are explored in video-based computer vision domain and sensor-based ubiquitous research areas. Vision-based human action or activity recognition approaches are based on RGB video sequences, or depth maps, or from skeleton data – taken from normal video cameras or depth cameras. On the other hand, sensor-based activity recognition methods are basically based on the data collected from wearable sensors having accelerometer, gyroscope, or so on. There are numerous applications on HAR, however, the healthcare, elderly support, and related applications become very important arenas with huge social and financial impact. Due to the advent of various IoT sensors, it becomes more competitive as well as easier to explore different applications.

All companies have things go wrong in their technical projects, from small things like a
2-week schedule delay to a large-scale product recall. How a development team handles
these issues can make a big difference in their customer relationships, and therefore on
their future business. No customer expects you to be perfect, but they do expect to be
able to trust you when things go wrong, and they expect you to handle the issue in a
professional manner. The Eight Discipline (8D) problem resolution process was
developed for this purpose. In this webinar we will review the process and how to use
it in an effective manner.

Digital technologies have been identified as key in addressing fundamental challenges associated with societal and economic objectives, such as improved quality of living for citizens, sustainable development and economic growth. In this context, 5G infrastructures will play a fundamental role in bringing these technologies to society transforming their every day’s life in the way services are provided, and businesses are run. However, this transformation requires new service capabilities that network operators need to support including: i) connectivity for a growing number of very diverse devices, ii) ubiquitous access with varying degrees of mobility in heterogeneous environments and, iii) mission critical services, supporting highly variable performance attributes in a cost and energy-efficient manner. These demanding and diverse requirements bring the need of a paradigm shift migrating from closed purposely developed infrastructures into open elastic ecosystems able to support a variety of very diverse services and end-users. These ecosystems will rely on flexible architectural models adopting convergence and integration of a variety of network and compute technologies, network softwarisation, hardware programmability and disaggregation of compute/storage and network resources. In this context, the webinar will focus on describing the relevant ecosystem and the key role that advanced optical networking solutions can play in the 5G era and beyond. Performance evaluation results as well as relevant demonstration activities will be also discussed.

The benefits of systems engineering are widely promoted with varying degrees of understanding. This
webinar is based on many years of experience designing and building complex systems incorporating all of the engineering disciplines (optics, mechanics, electronics, and software). For me, understanding and
using systems engineering has been a natural approach driven by my instincts (even before it was a newfound contemporary “thing”).
Systems engineering is about balance and perspective. The word “system” conveys the inherently multidisciplinary nature of the work. The engineering work is fundamentally to hold a perspective that makes sure nothing is overlooked that could affect the outcome and to make sure that the best balance is achieved between all of the competing needs and wants that drive the creation of the system in the first
Systems engineering starts with requirements, and then systems engineering follows on to serve and protect the requirements by constantly evaluating error budgets and the compliance of the system with the requirements as the system is designed and built.
In this webinar you will learn by example:
- How to approach the development of requirements that satisfies your stakeholders
- How to use one sentence definitions to clarify ideas and gain consensus
- How to define and manage expectations
- How to gain and confirm requirements “completeness”.

Sir Horace Lamb famously said that “I am an old man now, and when I die and go to heaven, there are two matters on which I hope for enlightenment. One is quantum electrodynamics and the other is the turbulent motion of fluids. About the former, I am really rather optimistic.” Although nowadays we can travel in less than a day’s time from Perth, Australia to London, UK, and from Newark, USA to Singapore, there are still many open scientific questions in the aerospace engineering realm, especially when it comes to supersonic and hypersonic flight. Mastering hypersonic wind tunnels is one key component of the research involved but advanced, accurate and non-perturbative diagnostics is another key part. In this talk I will discuss laser diagnostic efforts developed to tackle the latter, by concentrating on the research efforts of our group in this field by utilizing Coherent Rayleigh-Brillouin scattering (CRBS).
