Title: Generalization of Wigner time delay to sub-unitary scattering systems
We introduce a complex generalization of Wigner time delay (τ) for subunitary scattering systems. Theoretical expressions for complex time delay asa function of excitation energy, uniform and non-uniform loss, and coupling, are given. We find very good agreement between theory and experimental data taken on microwave graphs containing an electronically variable lumped-losselement. We find that time delay and the determinant of the scattering matrix share a common feature in that the resonant behavior in Re[τ] and Im[τ] serves as a reliable indicator of the condition for Coherent Perfect Absorption (CPA). This work opens a new window on time delay in lossy systems and provides a means to identify the poles and zeros of the scatteringmatrix fromexperimentaldata. The results also enable a new approach to achieving CPA at an arbitrary energy/frequency in complex scattering systems. We also investigate the statistical properties of the complex time delay as a function of uniform attenuation, utilizing both theory and experiments on microwave graphs.

Title: Dissipative Quantum Chaos in Floquet Systems
Dissipative Quantum Chaos is an emerging theory with the agenda to relateopen quantum and classical dissipative systems and eventually provide us with a tool to determine whether the evolution of an open system is“chaotic” or “regular”. Spectral properties of generators of quantum Markovian evolution are important in this respect. So far the emphasiswas put on generators of the Gorini-Kossakowski-Sudarshan -- Lindblad (GKS-L) form. Universal features were fund and some new concept, likeComplex Spacing Ration, were developed by using the GKS-L framework. However, stationary GKS-L generators do not provide a straightforward wayto semiclassical chaotic regime; therefore it is hard to relate open quantum and dissipative classical system with chaotic dynamics. In thistalk I address another type of generator, the so-called Redfield generators, which emerge in the Floquet-Markov theory and allows for asemiclassical transition. I use a driven Duffing oscillator as a model to illustrate spectral properties of Redfield generators.

Title: Microwave photonic crystals, graphene- and honomebilliards with threefold symmetry: a comparison with nonrelativistic and relativistic quantum billiards
It was demonstrated recently  that the properties of the resonance frequenciesand electric field strength distributions of rectangular microwave photonic crystals obtained in superconducting measurements with flat resonatorscontaining metallic cylinders arranged on a triangular grid , are well described by the tight binding model of a finite-size honeycomb-kagome latticeof corresponding shape. They are referred to as Dirac and honome billiards, respectively. We investigate properties related to the band structure of a Diracbilliard with a threefold symmetric shape and compare them to those of the corresponding graphene and honome billiards and relativistic neutrino billiards.Generally, the eigenstates of threefold-symmetric systems can be classified according to their behavior under rotation by 2π/3 into singlets, that are rotationallyinvariant, and pairs of doublets. We reveal for the latter in graphene and honome billiards in momentum space a selective excitation of the two inequivalentDirac points. For the understanding of the symmetry related features, we extend known results for nonrelativistic quantum billiards and the associated semiclassical approach [3,4] to relativistic neutrino billiards.

Title: Quantum chaos and quantum measurement – entropy production vs. unitary quantum dynamics
Quantum chaos and quantum measurement have one constitutive feature incommon: they capture information at the smallest scales to lift it to macroscopic observability. Fundamental bounds of the information content of closed quan- tum system with ﬁnite-dimensional Hilbert space their entropy production is exhausted in a ﬁnite time. Only in open systems where fresh entropy inﬁltrates from the environment, quantum dynamics (partially) recovers chaotic entropy production. Also in quantum measurements, a macroscopic apparatus observes a quantum system. Typically, notably in spin measurement, their results involve a com-ponent of randomness. The analogy with quantum chaos suggests that random outcomes of quantum measurements could, in a similar manner, reveal the en- tropy generated through the coupling to a macroscopic environment. Decoher- ence is required anyway to explain a crucial feature of quantum measurement, the collapse of the wavepacket. However, the subsequent step from a set of probabilities to deﬁnite individual measurement outcomes (the “second collapse”) still evades a proper understanding in microscopic terms and remains shrouded in concepts such as “quantum randomness”. Could this process be explained by the back action of the macroscopic apparatus on the measured system? To explore this hypothesis in the case of spin measurements, we adopt themodel of the measurement process proposed by Zurek and others, combined with a unitary approach to decoherence with heat baths comprising only a ﬁnite number N of modes, used in quantum chemistry and quantum optics. We ex- pect the dynamics of the measured spin for growing N to exhibit a scenario of increasingly irregular collapses and revivals: episodes of signiﬁcant spin polarization of increasing length alternating with spin ﬂips, determined by the initial condition of the apparatus. Preliminary analytical and numerical results con- ﬁrm our expectation. Complementing the quantum model, an analogous clas- sical system is presented: a particle, launched from the top of the barrier of a symmetric double-well potential, will fall into either well, depending on random impacts by ambient degrees of freedom.

Title: Eigenfunction non-orthogonality in a single-channel chaotic scattering: non-perturbative RMT results
I will discuss distribution of diagonal non-orthogonality factors (also known as the Petermann factors, or eigenvalue condition numbers) characterizing eigenmodes in a single-channel wave-chaotic cavity. The results are obtained within RMT framework for the eﬀective Hamiltonian formalism for an arbitrary strength of coupling to continuum.

Title: The trace formula for quantum graphs with piecewise constant potentials and multi-mode quantum graphs
It is well known that one may deﬁne a unitary quantum map for quantumgraphs with free particle movement on all edges. This is a key ingredient in the derivation of the trace formula by Kottos and Smilansky. We will generalise this quantum map to the case of piecewise constant potentials. Due to the appearance of evanescent modes this is in general not a unitary map. We will show that there is however a reduced unitary map that only acts on the edges where the modes are propagating. We will use this to derive a trace formula and discuss some examples. The same technique may be applied to multi-mode quantum graphs which may be considered as a special case.

Title: Non-stationarity and generic features in complex systems
Non-stationarity, i.e. the seemingly erratic change of important properties,is a characteristic feature of most complex systems. Equilibrium methods as in standard statistical mechanics do not apply, and new approaches are called for. We present two complementary approaches: ﬁrst, an analysis that identiﬁes diﬀerent operational states of complex systems and, second, a random matrix model explaining the heavy tails of multivariate amplitude distributions, i.e. the emergence of certain generic features. We illustrate our ﬁndings with examples from ﬁnance.

Title: Coupled cat maps as a toy model of many body quantum chaos
For decades, Arnold’s cat map served as a paradigm in classical and quan-tum chaos studies. I will discuss a natural extension of this model to many-body setting – a chain of cat maps linearly coupled by a nearest neighbor interaction. Despite of fully chaotic dynamics, the model turns out to be amenable to ana- lytical treatment due to the duality between its spatial and temporal dynamics. In particular, I will provide an explicit formula for correlations between local operators in suﬃciently long chains.

Title: Quantization of states in complex soft-wall quantum billiards
Semiclassical quantization yields the exact eigenenergy spectrum for har-monic oscillators. How well it works for general conﬁnements with complex potentials that the classical dynamics varies drastically with energy? In this talk we will show an example of semiclassical quantization of a complicated conﬁnement potential. Despite the complexity in the classical dynamics, the semiclassical quantization works well for the scarring patterns around periodic orbits in this system even for low energy eigenstates. Particularly, unlike the hard-wall conﬁnement of the two-dimensional electron gas where the recurrent scarring patterns are equally spaced in square root of E, a general feature of the soft-wall conﬁnement is that the recurrent scarring patterns are equally spaced in E, which has been identiﬁed previously as a signature for relativistic billiards with hard-wall conﬁnements. The underlying mechanism here is the similarity of the potential proﬁle that the particle felt and that for a harmonic oscillator. These results could be exploited in understanding the measurements of the den- sity of states and transport properties in two dimensional electron gas systems with random long-range impurities.

Title: Microwave studies of the three chiral ensembles in chains of coupled dielectric resonators
Following a recently published work on chiral random matrix ensembles and their experimental realizations (Phys. Rev. Lett. 124, 116801 (2020)), the present work describes in more detail the obtained results and setup. The work will establish in detail the link between Random Matrix Theory (RMT) for sys- tems with a chiral symmetry and how to create them with a ﬁnite set of mi- crowave resonators. The ﬁnite systems from the experimental setup are compared to analytical results for ﬁnite-size systems.

Title: Euler characteristic of graphs and Fermi golden rule
We present theoretical, experimental and numerical studies of the Euler characteristic χ for simple quantum graphs simulated experimentally by micro-wave networks . The Euler characteristic χ is deﬁned as a diﬀerence between the number of graph vertices V and the number of its edges E. It also deﬁnes the Betti number β = 1 −χ of independent cycles in a graph. Thus, together with the total graph length L the Euler characteristic χ is the most important topological and geometrical characteristic of graphs. We show theoretically and conﬁrm experimentally that the Euler characteristic can be determined from a ﬁnite sequence of the lowest eigenenergies λ1, . . . , λN of a quantum graph, without the need for a visual inspection of the system. Thus, from a graph spectrum one can ﬁnd out what is the number of its vertices and edges, provided that the graph is fully connected, or that the graph is planar (β ≤ 3). We also present the experimental results of a Fermi golden rule study in the case of two- and ﬁve-edge quantum graphs simulated by microwave networks. A Fermi golden rule gives rates of decay of states obtained by perturbing embedded eigenvalues of graphs .

Title: Graphs with preferred-orientation coupling and their spectral propertis
We investigate quantum graphs with the preferred-orientation couplingconditions suggested by Exner and Tater . In particular, we are interested in the high-energy limit of their spectra. These coupling conditions violate the time-reversal symmetry, for a particular energy, the particle approaching the vertex from a given edge leaves it through the neighbouring edge (for instance, to the left of the incoming edge) and this property is cyclical. It was previously shown that the vertex scattering matrix depends on the degree of the vertex; for an odd-degree vertex, the scattering matrix converges in the high-energy limit to the identity matrix, while even-degree vertices behave diﬀerently. This behaviour aﬀects the transport properties of these graphs.We study two models. The ﬁrst one is a ﬁnite graph consisting of edges of Platonic solids. We ﬁnd that the asymptotical distribution of the eigenvalues for the octahedron graph (having vertices with even degrees) is diﬀerent from the other Platonic solids (having vertices with odd degrees), for which the eigen- values approach the spectrum of the Neumann Laplacian on an interval. The second model consists of two types of inﬁnite lattices. For one of them, the transport at high energies is possible in the middle of the strip and is suppressed at the edges. For the other one, the transport is possible at the edge of the strip only.  P. Exner, M. Tater, Quantum graphs with vertices of a preferred orientation, Phys. Lett. A 382, 283–287 (2018). P.

Title: Emulating π orbitals in aromatic molecules using elastic waves: borazine
Mechanical waves have emerged as a paradigm of condensed matterphysics since with them many eﬀects of the latter can be emulated. Molecular π orbitals are of great interest in this area since they play a key role in electronic transport in 2D materials and aromatic molecules as benzene and borazine. Molecular π orbitals are of great interest in this area because they play a key role in the electronic transport of 2D materials and aromatic molecules such as benzene and borazine. In this work we show the design, construction and characterization of a mechanical structure, the artiﬁcial mechanical borazine, which emulates the π orbitals of the borazine. The structure consists of hexagonal res- onators, which act as artiﬁcial mechanical atoms coupled to each other through ﬁnite phononic crystals that act as artiﬁcial sigma bonds. When the resonant frequency of an artiﬁcial atom falls within the gap of the phononic crystal, the vibrations are trapped in it and interact weakly with neighboring atoms through evanescent Bloch waves. In this case, a tight-binding regime for mechanical waves emerge. Here these ideas are applied to emulate the π orbitals of bo- razine. The design relies on extensive ﬁnite element numerical simulations. The experimental results show an excellent agreement with both, the tight-binding formalism and with the numerical results. This work was supported by DGAPA-UNAM and CONACYT through projects PAPIIT-IN111021, and CB/284096, respectively.

Title: Simple approach to multiple scattering of waves from nontrivial media
Many interesting, subtle, and nontrivial eﬀects can be observed when clas-sical or quantum waves undergo multiple scattering. Depending on the size and structure of scattering media a plethora of phenomena can manifest themselves, including, but not restricted to, proximity resonances, coherent backscattering, strong (Anderson) localization, and others. Theoretical approaches to such ef- fects are often marred by inadequate descriptions of the scattering objects and too crude approximations made at the wave propagation level. Here some results concerning coherence eﬀects in multiple scattering are presented within a computational model that is extremely simple (although still realistic enough) at the level of the scattering medium description but which is exact at the wave propagation level. It is surprising how far one can go by modeling a scattering medium by discrete point-like dipoles and making no approximations to the wave propagation, thus describing scattering events in full generality within a given model. Apart from looking at the known examples from a diﬀerent perspective, some new results for both scalar and vector waves are given.

Title: Exactly solved models of chaotic many-body dynamics
One should be amazed with an unreasonable eﬀectiveness of random ma-trix theory to describe spectral ﬂuctuations in simple non-integrable many-body systems, say one dimensional spin 1/2 chains with local interactions. I will dis- cuss a class of Floquet (periodically driven) quantum spin chains – speciﬁcally, dual unitary Floquet circuits – where the random matrix result for the spectral form factor can be derived or even rigorously proven. Several other nontrivial exactly solvable features of the presented models, such as dynamical correlations or entanglement dynamics, will be discussed.

Title: Quantum searching on Markov chains
I will give an introduction into the quantum search algorithms on Markovchains introduced by Szegedy about 15 years ago and highlight some recent developments culminating in a proof by Apers et al. published as a preprint in 2019 showing that a quantum search can ﬁnd a set of marked vertices quadratically faster (in units of the hitting time) for any reversible Markov chain. I will make some speculations about the underlying mechanisms for the search to work and critically discuss the use of the hitting time as a measure for the search time.

Title: Does Longitudinal Light Prevent Anderson Localization?
Recent numerical simulations demonstrated the absence of an Anderson transition when light propagates in a dense medium filled with electric dipoles. We present a transport theory in which longitudinal waves induce a novel transport channel. The mixing of this channel with the usual transverse channel imposes a minimum conductivity. https://arxiv.org/pdf/2012.11210

Title: Random generators of Markovian evolution: a quantum-classical transition by superdecoherence
Continuous-time Markovian evolution appears to be manifestly diﬀerentin classical and quantum worlds. We consider ensembles of random generators of N-dimensional Markovian evolution, quantum and classical ones, and evaluate their universal spectral properties . It is shown, how the two types of generators can be related by superdecoherence. In analogy with the mech- anism of decoherence, which transforms a quantum state into a classical one, superdecoherence can be used to transform a Lindblad operator (generator of quantum evolution) into a Kolmogorov operator (generator of classical evolu- tion). By gradually increasing strength of superdecoherence, we observe a sharp quantum-to-classical transition. arXiv:2105.02369.

Title: Investigations of the enhancement factor in an open wave chaotic system with time-reversal-invariance violation
We show experimentally and conﬁrm theoretically that above a certain sizeof time-reversal T -invariance violation the increase of the openness of a wave chaotic system can lead to an increase of the elastic enhancement factor. In the experiment a quantum billiard with partially violated time-reversal invariance, characterized by the T -invariance violation parameter ζ [0, 1] is simulated with a ﬂat quarter-bow-tie microwave cavity which contains two cylindrical ferrites that are magnetized by an external magnetic ﬁeld. The elastic enhance- ment factor FM (η, γ, ζ) is investigated as a function of internal absorption γ and openness η. In these investigations we focus on the frequency range of strongest T -invariance violation where the increase of the number of open chan- nels causes a boost of the elastic enhancement factor FM (η, γ, ζ) instead of the expected lowering [1,2].

Title: Experimental demonstration of complex Wigner time delay in sub-unitary scattering systems
Wigner time delay has been appealing to physicists for its intuitive insights into the scattering properties of the complex scattering region. Here we developa complex generation of Wigner time delay in the sub-unitary scattering systems. By including both lumped and uniform loss and coupling eﬀects into the Scattering matrix, we model the complex time delay using the S-matrix zeros and poles, and establish connections between the time delay and Coherent Perfect Absorption (CPA). We demonstrate the idea of complex time delay in the sub-unitary scattering systems using a microwave graph experiment, and provide eﬀective methods for manipulating zeros and poles of the S-matrix. We also further investigate the statistical properties of the complex time delay as a function of uniform attenuation, utilizing both Random Matrix Theory (RMT) simulations and experiments on microwave graphs.

Title: Eigenfunction and eigenmode-spacing statistics in chaotic photonic crystal graphs
The properties of chaotic systems have been studied extensively in diﬀerent dimensionalities. Common statistical tests include the eigenmode-spacingand eigenfnction analysis. However, the experimental studies of chaotic graph eigenfunctions are generally conﬁned to just the wavefunction values at the nodes, because 1D graphs are usually constructed with coaxial cables. In the meantime, recent studies reveal that the chaotic graphs face challenges from trapped modes, which may be better analyzed and understood with eigenfunction analysis tools. Here, we propose photonic crystal (PC) arrays as an al- ternative physical system for chaotic graph studies. The graph bonds realized with defect waveguides which can be modeled by the telegrapher’s equa- tion for parallel plate waveguides. We have numerically demonstrated an ensemble of such PC-graphs and conducted both eigenfunction amplitude and eigenmode-spacing studies, and these statistical properties are in good agree- ment with the GOE predictions. Diﬀerent methods are tested in order to measure the graph eigenfunction proﬁle. Our proposed system can be readily applied to other statistical studies, such as inverse participation ratio, as well as further experimental realizations.

The Coronavirus pandemic of 2020 has shook the entire world by creating a standstill in all possible trade, business and economy across all boundaries. Restrictions are imposed on travelling overseas and locally as well with enforcement of strict lockdown. This gave opportunity to work from home system to flourish but eventually, it was understood that some work was best done by physically being present at the workplace. To carry out this task, introduction to completely touchless access management & attendance as well as interaction devices could make it feasible to restart working physically at the workspace.
By maintaining proper social distancing and ruling out the possibility of physical contact through any devices, Touchless Access Management System and Touchless Biometrics have started to gain popularity and demand in the market. The main reason for opting these methods is to ensure safety for all employees and working staff but at the same time, make it possible for them to get the desired work done in the specified time.
What is Touchless Biometric Access Management System?
Biometrics mainly include attendance system and access system which need physical contact but installing digital devices for completely contactless procedures, proper care can be taken while the work routine functions in the desired manner. The most common biometric system used is the fingerprint sensor. Many important organizations have issued directives to discontinue the use of fingerprint biometrics due to coronavirus threats. The physical world and workspace is full of things that unknown people have touched the surfaces of door knobs, light switches, fridge handle, and coffee machines etc.
Companies have begun to eventually sanitize anything and everything that is frequently touched by the staff members after certain intervals of time to ensure a safer environment for everyone. Majorly the door handles and fingerprint sensors need maximum sanitization, but it is physically impossible to completely sanitize it and make it virus-free. Biometrics based access control systems are typically used as additional security is needed hence compensate the cost of reduction in security to increase hygiene rating of the workplace.
Touchless biometrics includes Artificial Intelligence based facial recognition, QR scan access for visitors, Touchless Attendance System Management, Integrated Temperature Sensor Kit and UV chambers for disinfection. Artificial Intelligence based facial recognition units are perfect for carrying out daily attendance for employees and staff as it eliminates any kind of physical contact between the system and members. Traditional biometrics need fingerprints for marking daily attendance but the advanced AI facial recognition uses retina scans for marking the daily attendance and cannot be easily manipulated with a photo etc. QR code scan based access management allows entry and exit of members only when the requests are approved by the authorities and hence physical contact is ruled out!
7 Benefits of Touchless Biometrics Access Management System Post Covid-19
- Touchless Access Management technology is very much useful for the purpose of identity verification in the entire corporate sector where mass people movement is seen throughout the day. Biometric systems are very accurate in detecting identity of people by scanning retinas and faces.

The MSI MEG Trident X appears to be like great, would not take up a lot house, and runs demanding games at high settings. The fundamental of Ampere was to take every little thing NVIDIA discovered with its Turing architecture. When the game is launched next time, the corresponding preset will take impact mechanically, giving gamers the appropriate gaming visible they need. Loaded with 5888 shader cores is has the means to recreation even a bit intoxicating. It takes the throne of the quickest Pc gaming graphics card with nothing coming even close to it. While there were solely three RTX titles around the launch of the RTX 20 series playing cards, NVIDIA now has at the least 28 titles that make the most of their RTX function set to offer real-time ray tracing with more coming soon. The preliminary launch of Ampere for shoppers entails the GeForce RTX 3070 8GB GDDR6, RTX 3080 10GB GDDR6X, and what we test right this moment, the 24GB GDDR6X based mostly premium flagship, the mighty mo, the GeForce RTX 3090. The lineup practically doubles ray-tracing efficiency with Gen2 ray-tracing cores and 3rd iteration Tensor cores. On September 1st of the year, 2020 NVIDIA declared three preliminary Ampere graphics cards in its inaugural launch wave.
With roughly half that shader processor count, we now meet the NVIDIA GA104 GPU, initially for use solely within the GeForce RTX 3070 graphics cards. The Ampere lineup presents faster shader efficiency, faster ray tracing performance, and faster AI performance. Every week earlier than bulletins, specifications of the GeForce RTX 3070, 3080, and 3090 took a twist; the shader core rely mysteriously doubled up from what all people anticipated. This product will sit spot on GeForce RTX 2080 Ti performance levels and, in due time, might be its replacement. We're on the cusp of some of the most important changes in know-how trends, most of which will likely converge in Metaverse, the subsequent major platform in computing after the world vast web and mobile. In addition to the specs/worth replace, NVIDIA's RTX applied sciences are being widely adopted main recreation engines and APIs equivalent to Microsft DirectX (DXR), Vulkan, Unreal Engine, Unity, and Frostbite. Currently, NVIDIA has thirteen game engines which can be leveraging their RTX technologies for use in their upcoming and current games whereas each Vulkan and DirectX 12 Ultimate APIs are part of the RTX ecosystem on the Pc platform. It gives knowledge speeds of close to 1TB/s system memory bandwidth for graphics card applications, maximizing sport and app efficiency.
The GeForce RTX 3070 comes with memory at speeds of 14 Gbps. When it comes to memory, the GeForce RTX 3070 options eight GB of GDDR6 reminiscence. A 3070 Twin Edge (non-OC model) is € 599 although (including VAT) or 606 USD before taxes. Yea those Zotac Twin Edge are very loud too. One retailer near my is a Zotac accomplice and will get a whole lot of inventory from them, but primarily Twin Edge playing cards. The Ampere GPU structure has loads to be talked about in this evaluate, but so does the brand new RTX lineup. The first wave of announcements would see the GeForce RTX 3080 and 3090 being released first, and, as a little bit of a shock, the GeForce RTX 3070 would be arriving in roughly the identical timeframe as well. Keep reading to see more information. Third-gen Tensor Cores: New devoted Tensor Cores, with up to 2x the throughput of the previous era, making it faster and extra efficient to run AI-powered technologies, like NVIDIA DLSS, and 238 Tensor-TFLOPS of processing power.
Along with the CUDA cores, NVIDIA's GeForce RTX 3070 additionally comes full of next-generation RT (Ray-Tracing) cores, Tensor cores, and brand new SM or streaming multi-processor units. NVIDIA's GeForce RTX 30 sequence is made up of a diverse portfolio of graphics cards. At the heart of the NVIDIA GeForce RTX 3070 graphics card lies the GA104 GPU. With that said, the GeForce RTX 3080 replaces the RTX 2080 Super at the identical value point and the GeForce RTX 3070 replaces the GeForce RTX 2070 Super at the identical price level. Given this trend, we might see the extra mainstream variants value just as much as their RTX 20 Super collection playing cards however with the next efficiency out of the box. Starting at $4,198, this massive 18-inch laptop boasts not one but two Nvidia GTX 1080 GPUs in SLI with an Intel Core i7 CPU and two PCIe SSDs in Super RAID 4 configuration, simply to call a few specs. While you could most likely use one of the gaming machines for many content creation, MSI has tuned a few laptops strictly with creation in thoughts. Yes, other laptops are more highly effective and can get you sooner body charges, however they're also going to offer your bank steadiness more of a success.

Spring is in the air and a time when the focus for homeowners shifts to their outdoor space. Katie Plumstead, Group Marketing Manager, Scolmore Group, looks at ways professional installers can bring power to the outdoors to create a safer, brighter and more welcoming recreational space.
Whatever outdoor project is being planned, the advice is always to make sure a reputable professional is engaged to ensure that any work is carried out safely and meets all the required regulations. This is where professional electricians come to their own, with the necessary skills and knowledge to advise their customers on how best to bring power to the outdoors and to upgrade or improve existing lighting installations.
Across the Scolmore Group there is an array of products that installers can call on to provide power, lighting and security protection to enhance their customers’ outdoor spaces and some of these are highlighted here, giving wholesalers a heads up on what they should be stocking to meet demand.
Power can be brought safely to sheds, office spaces, heating and hot tubs, with the Aquip66 range of IP66 rated, easy-to-install 10A and 20A weatherproof outdoor switches and sockets.
The IP66-rated weatherproof socket and switch enclosures offer users a single fix installation. The range includes 1 and 2 Gang switch enclosures which utilise MiniGrid single width switch modules which are rated at 10A, as well as 1 and 2 gang switches that utilise the GridPro range of modules and offer 20A switching options. A 13A switched fused connection unit is also available with a semi-transparent cover with neon power indicator, as well as with a standard cover.
The right connection
Providing a strong, quick and reliable solution when working with cables and power outdoors is Unicrimp’s Q-NECT IP66 Weatherproof Junction Box. Designed to make installations more efficient, it can house four of the 3 Port Lever Connectors using the 360° detachable cradle and with a curved lid, it provides additional space for wires. The lid is locked using quarter turn fasteners. There are ten membrane entry points, and protection against moisture and dust is enhanced with the self-sealing membranes which provide a faster and more secure cable entry whilst at the same time maintaining the IP66 rating. These junction boxes with semi-transparent lids are available in a black or anthracite grey finish, with the anthracite grey colour option designed to match the Click Aquip66 weatherproof socket and switch enclosures, which are also available with the same semi-transparent lids.
Smart control outdoors
With power brought to the outdoor spaces, Scolmore’s Click Smart+ range will allow remote control of any electrical elements outside – switching on lighting, controlling an outdoor appliance or sprinklers, or the ability to switch off power for security.
The Click Smart+ range has been created to simplify and streamline connected home products – lighting controls, smart sockets, security cameras and sensors. It utilises Zigbee technology – one of the most widely adopted smart home communication protocols. Zigbee certified devices require the Click Smart+ Hub and communicate with each other using a mesh network. This creates multiple pathways for the connection of multiple smart home devices without compromising signal and communication range.
Working alongside Click Smart+ is the Fort range of smart security products from Scolmore Group company, ESP. The range includes intruder alarms, video doorbell, video security light, sensors and a selection of 1080p cameras. They all operate under the same ‘Click Smart+’ app – which is completely subscription-free, with no additional fees incurred. By bringing the operation of the Fort range under the Click Smart+ app from Scolmore, users will have control of a raft of connected home and security products all from one secure, easy to access platform.
Lighting the way
When it comes to lighting solutions for the garden, it is worth considering the main functions that are required. These could include accessibility, highlighting of particular areas of the garden, security and aesthetics.
Ovia has a raft of lighting solutions for the outdoors including the recent addition of a solar powered security light. A more sustainable lighting solution, The Zonne has a radiant 8W output, and casts a crisp 4000k temperature glow at an impressive 950 lumens. The fitting is IP65 rated and it has a charge time of 5-6 hours to fully and has two working modes – Mode A: 3~5 Nights and Mode B: 2~3 Nights. It is designed to be installed at a height of four metres and comes with three metres of connection cable.
Ovia’s Pathfinder LED floodlights are an ideal way to provide ambient lighting around the garden – lighting up walkways, driveways, as well as highlighting architectural features when used as an up-lighter. The range offers 40 options from 10W to 300W, with fittings up to 50W available in both black and white finishes and they come in a choice of Warm White or Cool White colour temperatures. The standard range can be used with remote sensors PIRs (indoor and outdoor) or Microwave sensors (indoor only) as well as with the Click Smart+ control system.
With power and lighting in the garden all under control, full advantage of its benefits can be taken all year round.

Make some noise with your next project! The MP3 Trigger board is built to make MP3 sound integration easier than ever. The board has 18 external trigger pins that will directly trigger pre-selected MP3 tracks, and a full-duplex serial control port that provides full transport control, remote triggering for up to 256 tracks, and fast real-time volume control. MP3s are stored on FAT16 formatted SDSC or FAT32 formatted SDHC micro-SD flash memory cards. In addition, optimized code can achieve 192Kbps stereo playback from a wider range of cards.
The heart of the MP3 Trigger board is the Cypress PSoC CY8C29466-24SXI microcontroller which serves up MP3 data to a VLSI VS1063 audio codec IC. This version also supports an optional initialization file that can be used to set the serial port baud rate as well as to reprogram any of the 18 trigger inputs to alternate functions, including random and sequential track selection, transport controls and even volume up/down. Each conventional trigger can be set to either allow immediate restarts, or to lock out restarts if audio is playing. Also, a new trigger filename convention provides greater flexibility in naming your MP3 tracks and makes file management easier.
This version of the MP3 Trigger includes firmware that supports the use of an initialization file on the microSD card that can be used to change the serial baud rate, as well as to repurpose any of the 18 trigger inputs to alternate functions, such as random and sequential triggers, navigation controls and even volume controls. In addition, a restart lockout option can be used to prevent any trigger from starting a track if audio is already playing. Using these features, custom applications can often be implemented without the use of a separate microcontroller.
Note: This product is a collaboration with Robertsonics. A portion of each sales goes back to them for product support and continued development.

Freescale unveils magnetic memory chip
Achieving a long-sought goal of the $48 billion memory chip industry, Freescale Semiconductor Inc. announced the commercial availability of a chip that combines traditional memory's endurance with a hard drive's ability to keep data while powered down.
The chips, called magnetoresistive random-access memory or MRAM, maintain information by relying on magnetic properties rather than an electrical charge. Unlike flash memory, which also can keep data without power, MRAM is fast to read and write bits, and doesn't degrade over time.
Freescale, which was spun off of Motorola Inc. in July 2004, said Monday it has been producing the 4-megabit MRAM chips at an Arizona factory for two months to build inventory. A number of chip makers have been pursuing the technology for a decade or more, including IBM Corp.

Meet The Robots
SmallSizeHolland’s robots are the result of years of design, innovation, and development by a multidisciplinary team. So far there have been four generations of robots which have been worked on.
Gen1 was a try-out to see if it was feasible for Saxion to compete in Small Size League soccer. Gen1 was made entirely by a group of computer science students. The robots were made mostly out of 3D-printed parts and communicated via radio-frequencies (NRF). Gen1 robots only had a dribbler and a kicker.
During the development of Gen2 robots an electrical engineer joined the team. This allowed the team to create a custom motherboard for the robot.
The team also added a chipper to the system and built the dribbler motor in the dribbler itself. Gen2 robots are powered by an mbed. The Gen2 robots started using the iconic Small Size League hoods.
Finally some mechanical engineers joined the team for Gen3. This allowed Small Size Holland to completely redesign the robot. The robots changed to a four wheel robot instead of a three wheel design. The redesigned hood was almost twice as light as the Gen2 hood.
The mechanical engineers also made the robots more modular, making it easier to repair robots. In Gen3 custom solenoids were implemented. The mbed from Gen2 robots got switched out for a custom micro-controller with a dual core and FPGA. The robots also switched to WiFi for communication instead of NRF.
The current generation is Gen4. Small Size Holland decided to switch back to three wheels after learning much about the four wheel design. The frame is made out of a strong and durable plastic in order to reduce weight. During the development of the Gen3 robots the mechanical engineers focused on modularity whereas for Gen4 it was up to the electrical engineers to focus on modularity. The hood also got a redesign by our industrial product designer.

SuperO C9Z490-PGW is a unique and well-designed motherboard. Its server origins are evident, giving us high stability and excellent performance. Having said that, the more advanced configurations in the BIOS may cause issues with some users. There is however, an easy mode that is suitable for less advanced users. Enthusiasts and overclockers should feel great with various settings in BIOS/UEFI.
SUPERO, the consumer-oriented sub-brand of Supermicro brings its latest professional gaming flavor to Intel’s updated 300 series platform in the form of the Pro Gaming C9Z390-PGW. Featuring flagship gaming features like support for 10-Gigabit Ethernet, Dual M.2 and Dual U.2 storage connections, DDR4-4000+ memory speeds, 140W TDP CPU’s and up to Quad graphics solutions thanks to the integrated PCIe switch that gives you 32 PCIe lanes for x16/x16 or x8/x8/x8/x8 connections to the CPU for unsurpassed performance. With a flagship feature list and an enterprise pedigree, how does the C9Z390-PGW do in the real world? Let’s find out!
Today, I will be taking a look a the flagship arrival in Supermicro’s latest gaming motherboard portfolio, the SuperO C9Z390-PGW. SuperO is the official gaming brand of Supermicro which produces high-end and mainstream motherboards for the gaming audience. These boards are known to utilize the high-quality precision and components of the server level design that you expect from Supermicro and that is essentially what I am going to test out in this review.
Today we take at our first Supermicro Z390 motherboard, the C9Z390-PGW. It is positioned to be a very high-end motherboard with 10Gbit LAN and even a chip that doubles PCI-E lanes. Doubling the x16 lanes from the CPU to x32 gives the motherboard a special feature not many other motherboards can claim to have. Let's take a look at the new motherboard.
Looking for a new Z390 motherboard for your work or gaming PC? Cool, SuperMicro has their new C9Z390-PGW. However, are you also tired of that “slow” Gigabit networking? Then this may be the motherboard for you. Not only does it pack in a lot of high-end features, but it also has the incredible Aquantia AQC107 10G Ethernet Controller, as well as Intel PHY i219V Gigabit LAN, and 802.1ac WiFi+BT5.0. Most consumers don’t need 10G LAN, or even three different network connections onboard, but there’s a growing market and you know who you are.
The Z390 launch is going off in style, with us having quite a few boards for this launch, including two from Super Micro. However, this one is pretty special, as it’s the only board we have for review that isn’t ATX! Even better, it’s mini-ITX, making it attractive for those seeking to build more compact systems around the Z390 platform. With support for both 8th and 9th Gen Intel CPUs, this may prove to be a very popular motherboard. Of course, we’ll be testing ours with the new flagship Intel Core i9-9900K, which is sure to put the motherboard through its paces better than any other.
