Sound is a disturbance that passes through a medium as longitudinal waves, causing the sensation of hearing. The speed of sound differs depending on the molecular composition of the medium. When sound waves encounter barriers in an enclosed space, they can be reflected, absorbed, refracted, diffused, diffracted, or transmitted. Reflection occurs when the wavelength is smaller than the surface, causing the waves to hit the enclosure continuously until the energy reduces to zero. Absorption occurs when some of the wave's energy is lost through transfer to barrier molecules. Refraction is the bending of sound waves when passing between different media. [END SUMMARY]

Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms for those who already suffer from conditions like anxiety and depression.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.

5. ACOUSTIC PROBLEMS
Most audition areas do tend to be rectangular with parallel walls and large flat surfaces, since this is the easiest and most usual way of constructing buildings.
Besides, the choice of covering materials for the rooms' interior does not usually get much attention either.
This is the least favourable way of creating a space for music audition or recording: parallel walls and flat ceilings create echo-waves and stationary resonant
frequencies, with several harmonics, that actually alter and distort the sound reproduced by the sources, thus creating like a "trash sound" that disturbs and
hampers audio perception.
To listen or work under these conditions may become a gruelling work and a daunting task that electro-acoustics will never solve.
In order to create a room with good acoustics, space modulation and all its covering materials must be enhanced.
Direct sound from the source.

JOCAVI® SOLUTIONS
By creating an acoustic conditioning adequate to the room in question, be it an auditorium, studio or audition room, JOCAVI® panels have the solution. They
correct common acoustic problems in non-treated rooms. We provide twenty-two different models to treat specific situations and effectively solve the acoustic
problems in rooms. These acoustic panels, when duly applied, control reverberation time, correct central resonances, echoes, early reflections and all the
"trash sound" present in excessive levels, thus making audition real in its controlled space.
Essentially, JOCAVI's philosophy is to develop and manufacture acoustic treatment panels, by combining sound diffusion and absorption solutions, thus
allowing a varied and diversified offer of these products. Rooms which are treated with our range of products have a very balanced genuine acoustic
characteristic, which provides them with excellent sound perception. In order to help you plan your needs, our volumetric acoustic simulator JAS® is available
online, where you may simulate your room in detail by using our products to their full potential.

8. CERAFLECTOR®
Diffusion Panel
The acoustic treatment panel CERAFLECTOR ® is a 3D controlled-
-dispersion multidirectional reflection panel. It is built with the purest enamelled porcelain and its modular design makes it
unique in the market.
The angles of reflection of this radial diffusion panel were thoroughly calculated. The depth factor is logarithmically varied and
it is, therefore, a three-dimension omnidirectional reflection panel.
The panel CERAFLECTOR® controls primary reflections and fragments them in 64 vertices of incidence using the theoretical
numerical sequence ratio of the primitive root as a basis for calculation.Thus, it produces exceptional results of sound diffusion
in all directions and provides spaces with considerable sound perception.
M1 fire resistant. Available in several colours.

CORALREEF®
Diffusion Panel
The Coralreef® is a 3D controlled-dispersion acoustic diffusion panel. It is made of high-density polystyrene and its finishing membrane
provides it with the intended acoustic qualities.
Its angular appearance gives dynamics to any space and provides a decorative effect and attractive combinations.
This acoustic panel is installed on ceilings and walls. Its low weight makes it the ideal product for use on false ceilings, on its own or
alternated with flat modules when refinement and quality are required.
The calculation basis was the theoretical numerical sequence ratio of the primitive root, thus providing excellent results of sound
diffusion in all directions. The depth factor is logarithmically varied, and it is, therefore, a three-dimension omnidirectional reflection
panel.
Due to its quite sinuous shape with deep recesses, as well as the raw material it is made of, this product also has a considerable
associated absorption coefficient.
O Coralreef® é um painel de tratamento acústico difusor 3D de dispersão controlada. É produzido em poliestireno de alta densidade e
a sua película de acabamento confere-lhe as propriedades acústicas pretendidas.
O seu aspecto anguloso dá dinâmica a qualquer espaço, proporcionando um efeito decorativo e combinações atraentes.
Este painel acústico aplica-se em tectos e paredes. O seu baixo peso torna o Coralreef® o produto ideal para ser usado em tectos
falsos, sozinho ou alternando com módulos lisos, quando se pretende requinte e qualidade.
Como base de cálculo, foi usada a razão de sequência teórica numérica da raiz primitiva, proporcionando resultados estupendos de
difusão de som em todas as direcções. O factor profundidade é de variação logarítmica sendo, portanto, um painel de reflexão
omnidireccional em três dimensões.
Por causa da sua forma bastante sinuosa com reentrâncias profundas e também da matéria-prima com que é fabricado, este produto
oferece também um coeficiente de absorção associado apreciável.

9. DYNAMICFLOW®
Diffusion Panel
JOCAVI® has developed this acoustic diffusion panel by using non-linear convex shapes, based on a set of three ellipses which were
later altered and optimised in order to achieve an oval shape with better diffusion angular coverage.
The external raw material of this panel was selected out of some materials that have the fastest and most specific properties required for
a diffuser with these characteristics. However, PETG still has some advantages, namely UV protection, impact resistance and fire
resistance M2 .
Dynamicflow's interior is composed of a substance made of impregnated mineral fibres and textiles, which gives this product a specific
mass and also contributes to its consistence. The back part consists of an even surface. Its shape adjusts to even surfaces. It can be
used on "T" profile false ceilings or on walls, by using our glues or fastening materials.
A JOCAVI® desenvolveu este painel difusor acústico usando as formas convexas não lineares, baseado num conjunto de três elipses
posteriormente alteradas e optimizadas, a fim de se conseguir uma forma oval com melhor cobertura angular de difusão.
A matéria-prima exposta deste painel foi eleita entre algumas matérias que reúnem as mais rápidas e particulares propriedades
exigidas para um difusor com esta característica. Contudo, o PETG revela ainda algumas vantagens, nomeadamente a protecção UV,
a resistência ao choque e a classificação ao fogo M2.
O miolo interior do DYNAMICFLOW® é composto por uma substância composta de fibras minerais e têxteis impregnados, que confere
ao produto uma determinada massa e contribui também para a sua consistência.
A parte de trás descreve uma superfície plana. A sua forma ajusta-se a uma aplicação em superfícies planas.
Pode ser usado em tectos falsos em perfil "T" ou em paredes, usando as nossas colas ou acessórios de fixação.

EFFECTFUSER®
Diffusion Panel
Diffusion shells are acoustic treatment elements used in large volume rooms, such as theatres and auditoriums, where orchestral
concerts or mere recitals take place.
The installation of these acoustic diffusion components aims to project the natural sound from the instruments and maintain some
liveliness in the room's acoustics.
JOCAVI's Effectfuser® has been designed at the scale of these needs. It is a large-sized diffuser that provides a very homogeneous
diffusion within the diffuse sound spectrum. Due to its shape and depth, the Effectfuser® has a high diffusion coefficient on medium/low
frequencies, thus making it more balanced when compared with other diffusers. This piece can be coupled and multiplied in order to
suit each room's project.
When mounted, several modules must be grouped in order to obtain a diffusion area that is proportional to each space. They are
properly positioned on ceilings or walls in order to obtain sound diffusion at the intended angles.
Effectfuser® may also be used, like any other JOCAVI® diffusion model, in combination with other models of absorption panels.
As palas difusoras são elementos de tratamento acústico utilizadas em salas de grande volumetria, como Teatros e Auditórios, para
realização de concertos com orquestras ou de simples recitais.
A intenção da instalação destes componentes difusores acústicos é projectar o som natural dos instrumentos e manter alguma
vivacidade na acústica da sala.
O EFFECTFUSER® da JOCAVI® é uma peça ideada à escala destas necessidades. É um difusor de grandes dimensões que
proporciona uma difusão muito homogénea no espectro sonoro difuso. Devido à sua forma e profundidade, o EFFECTFUSER® tem
um elevado coeficiente de difusão nas médias/baixas frequências, tornando-o assim mais equilibrado quando comparado com outros
difusores. Esta peça pode ser acoplada e multiplicada de forma a adequar-se ao projecto de cada sala.
Na montagem, devem ser agrupados vários módulos a fim de se obter uma área difusora proporcional a cada espaço. Aplicam-se no
tecto ou na parede, posicionados de forma apropriada, para que se obtenha a difusão do som nos ângulos pretendidos.
O EFFECTFUSER® pode também ser usado, como qualquer outro modelo difusor da JOCAVI®, combinado com outros modelos de
painéis absorventes.

TUNEFLECTOR®
Diffusion Panel
JOCAVI is presenting this design proposal in diffusion products which is not as common. This has been done on the basis of the
positive aspects of complex-shaped diffusers and the tasks carried out in the field of diffusion, to the detriment of the usual numerical
sequences that are repeated to build diffusers. When a diffuser has a complex structure, as opposed to the identical or retrograde
repetitions, it adopts algorithms that originate a series of N elements, thus causing an optimal musical characteristic.
Numerically structured diffusers scatter the sound effectively but have some inherent associated absorption. This model is meant to be
an acoustic diffuser with the best scattering features possible coupled with the lowest absorption coefficient.
Thus, Tuneflector® has been conceived as a sound wave diffuser for walls and ceilings of music audition and performance rooms.
This new model has abrupt joints with planes that lean on each other, which are always different, but do not cause big concavities or
parallelisms.
Design was an ever present concern in the manufacture of this product, in order not to make it unwanted due to its shape, regardless of
its obvious use. The result is a product with strong aesthetics, considered adorable by some and somewhat aggressive by others.
Com base nos aspectos positivos dos difusores de formas complexas bem como nos trabalhos realizadas no campo da difusão, em
detrimento das normais sequências numéricas que se repetem na elaboração dos difusores, a JOCAVI® apresenta esta proposta de
design menos vista em peças de difusão. Quando um difusor possui uma estrutura complexa, ao inverso das repetições idênticas ou
retrógradas, adopta algoritmos que resultam numa série de N elementos originando uma óptima característica musical.
Os difusores oriundos de formas numéricas espalham bem o som, mas têm inerentemente alguma absorção associada. O que
sugerimos com este novo modelo é um difusor acústico que tenha as melhores características de espalhamento possível com o
menor coeficiente de absorção acoplado.
Concebeu-se desta forma o Tuneflector® difusor de ondas sonoras para paredes e tectos de salas de audição e de performance
musical.
Este novo modelo possui articulações abruptas com planos encostados uns aos outros, sempre diferentes, sem causar grandes
concavidades nem paralelismos.
TUNEFLECTOR®
Uma preocupação presente na elaboração desta peça foi o design, não tornar o produto indesejado devido à sua forma,
independentemente da sua óbvia utilidade. Resultou numa peça com uma forte expressão estética, em algumas opiniões adorável e
noutras algo agressivas.

11. SQUARYDIFFUSOR®
Diffusion Panel
The Squarydiffusor® is a diffusion panel that has a higher balance between diffusion/absorption. It is a 2D quadratic diffuser with five
slightly uneven gradients. The Squarydiffusor® is made of low density clay paste.
Due to its quadratic shape and the raw material it uses, its diffusion and absorption features are well balanced for a diffusion panel.
The Squarydiffusor® enables quite good control of acoustics by fragmenting the reflected energy, while the absorption factor is not too
high.
This product is therefore quite recommended for installation in small-sized rooms, by making the acoustics of those spaces quite
homogeneous.
O Squarydiffusor® é um painel difusor que apresenta um maior equilíbrio difusão/absorção. É um difusor quadrático 2D de cinco
desníveis com curta discrepância, fabricado em pasta de barro de baixa densidade.
Devido à sua forma quadrática e à matéria-prima que utiliza, este produto revela um bom equilíbrio de características de difusão e
absorção, tratando-se de um painel difusor.
O Squarydiffusor® permite uma acústica bastante controlada, fragmentando a energia reflectida, sem que o factor de absorção seja
demasiado acentuado.
É por isso, um produto bastante recomendado para aplicação em salas de pequenas dimensões tornando a acústica desses espaços
bastante homogénea.

FX
TwoFX® is an acoustic treatment panel with two entirely different faces: a diffusion face and an absorption face which do not
have any similarities at all. There is an ingenious fixing system, in the middle of the panel, that allows it to change from one face
to the other and fix it at different 45o angles quite easily.
This panel is particularly appropriate for one-room recording studios that have to record several different setups, thus
requiring different acoustic features.
It enables the room's acoustics to change drastically in just a few minutes. It provides several combinations with different
results.
On the diffusion face, a sequence of the 7 musical notes followed by a mathematical routine of transpositions, inversions and
retrogrades was considered as a basis. The shapes are predominantly convex, but there are also some concave shapes that
The Convexabsorber® is an absorption panel which is efficient at absorbing low and medium frequencies. It was designed to be
installed on ceilings and walls.
It is manufactured by combining two techniques: a box tuned to 120 Hz, which is efficient at low frequencies, and a mathematically
studied absorbent labyrinth, which provides this product with an excellent performance in absorbing sound.
Given its characteristics, this panel balances reverberation times and echoes in large-sized rooms, auditoriums etc.
Because of its large and convex shape, it also is a diffuser with a large dispersion surface.
When the areas so require, these panels can be installed alternately at 90º angles, the dispersion thus being on two plans.
The panel Convexabsorber® was designed and tested in order to guarantee its high performance in controlling sound energy, by
