Product Design Trends in 2024 | Teenage EngineeringsPixeldarts
The realm of product design is a constantly changing environment where technology and style intersect. Every year introduces fresh challenges and exciting trends that mold the future of this captivating art form. In this piece, we delve into the significant trends set to influence the look and functionality of product design in the year 2024.
How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).
AI Trends in Creative Operations 2024 by Artwork Flow.pdfmarketingartwork
Creative operations teams expect increased AI use in 2024. Currently, over half of tasks are not AI-enabled, but this is expected to decrease in the coming year. ChatGPT is the most popular AI tool currently. Business leaders are more actively exploring AI benefits than individual contributors. Most respondents do not believe AI will impact workforce size in 2024. However, some inhibitions still exist around AI accuracy and lack of understanding. Creatives primarily want to use AI to save time on mundane tasks and boost productivity.
Organizational culture includes values, norms, systems, symbols, language, assumptions, beliefs, and habits that influence employee behaviors and how people interpret those behaviors. It is important because culture can help or hinder a company's success. Some key aspects of Netflix's culture that help it achieve results include hiring smartly so every position has stars, focusing on attitude over just aptitude, and having a strict policy against peacocks, whiners, and jerks.

5 Public speaking tips from TED - Visualized summarySpeakerHub

Google's Just Not That Into You: Understanding Core Updates & Search IntentLily Ray
1. Core updates from Google periodically change how its algorithms assess and rank websites and pages. This can impact rankings through shifts in user intent, site quality issues being caught up to, world events influencing queries, and overhauls to search like the E-A-T framework.
2. There are many possible user intents beyond just transactional, navigational and informational. Identifying intent shifts is important during core updates. Sites may need to optimize for new intents through different content types and sections.
3. Responding effectively to core updates requires analyzing "before and after" data to understand changes, identifying new intents or page types, and ensuring content matches appropriate intents across video, images, knowledge graphs and more.

Dennis Ritchie, a computer scientist, was able to identify the gaps and tap out the best features from both B and BCPL languages to invent a new hybrid.
Hence, C was born in 1972 at Bell Laboratories. A remarkably simple and highly readable programming language resulted in groundbreaking advancements in the IT industry.
✅What is C++ Programming?
C++ is an enhanced and extended version of C programming language, developed by Bjarne Stroustrup in 1979 as part of his Ph.D. project. Bjarne developed what he called ‘C with Classes’ (later renamed C++) because he felt limited by the existing programming languages that were not ideal for large scale projects. He used C to build what he wanted because C was already a general-purpose language that was efficient and fast in its operations.
✅C++ Career Prospects:
With just C++ programming expertise, you will have excellent job opportunities, salaries, and career prospects. However, for a career based on programming languages such as Java and Python (which are in more demand than C++) or for careers based on front-end, back-end, and full-stack

1. Core updates from Google periodically change how its algorithms assess and rank websites and pages. This can impact rankings through shifts in user intent, site quality issues being caught up to, world events influencing queries, and overhauls to search like the E-A-T framework.
2. There are many possible user intents beyond just transactional, navigational and informational. Identifying intent shifts is important during core updates. Sites may need to optimize for new intents through different content types and sections.
3. Responding effectively to core updates requires analyzing "before and after" data to understand changes, identifying new intents or page types, and ensuring content matches appropriate intents across video, images, knowledge graphs and more.

Dennis Ritchie, a computer scientist, was able to identify the gaps and tap out the best features from both B and BCPL languages to invent a new hybrid.
Hence, C was born in 1972 at Bell Laboratories. A remarkably simple and highly readable programming language resulted in groundbreaking advancements in the IT industry.
✅What is C++ Programming?
C++ is an enhanced and extended version of C programming language, developed by Bjarne Stroustrup in 1979 as part of his Ph.D. project. Bjarne developed what he called ‘C with Classes’ (later renamed C++) because he felt limited by the existing programming languages that were not ideal for large scale projects. He used C to build what he wanted because C was already a general-purpose language that was efficient and fast in its operations.
✅C++ Career Prospects:
With just C++ programming expertise, you will have excellent job opportunities, salaries, and career prospects. However, for a career based on programming languages such as Java and Python (which are in more demand than C++) or for careers based on front-end, back-end, and full-stack

●
Veličina závislá zejména na a) povrchové
teplotě, b) vlnové délce a c) úhlu měření
●
V rovnovážném stavu platí:

Emisivita
●
Povrchová teplota zatepleného
panelového domu je přibližně
homogenní. Na termogramu se
však zdá, že místa s nápisem
jsou až o 5 °C chladnější. Tato
chyba měření je způsobena
rozdílnou emisivitou barev

Černé těleso
●
Černé těleso je z hlediska bezdotykového měření teploty
objekt, který má emisivitu povrchu rovnou 1 (pozor na
spektrální závislost).
●
Z toho pak vyplývá, že má nulovou odrazivost a nulovou
propustnost (základní vztah říká, že emisivita + odrazivost +
propustnost = 1). Z jednotkové emisivity povrchu pak vyplývá,
že jeho pohltivost je také jednotková (neboť pro ustálený stav
platí Kirchhoffův zákon termální radiace, který říká, že
pohltivost = emisivita).

●

●
deskové černé těleso - povrch s vysokou emisivitou je
realizován prostřednictvím “drsného” povrchu o vysoké
emisivitě. Na jmenovitou teplotu je vyhříván přímo povrch
tělesa.

Barevná teplota
●
Bezdotykové měření teploty je principiálně velmi starý princip
využívaný při zpracování kovů (využíváno dávno před zavedením
pojmu „teplota“)
●
Světlo určité barevné teploty má barvu tepelného záření vydávané
černým tělesem, zahřátým na tuto teplotu.
●
Barevná teplota je vhodná pro chrakterizaci pouze takového záření,
které vykazuje stejný barevný vjem jako složené tepelné záření
(sálání) dokonale černého tělesa, tedy se spektrem daným
Planckovým rozdělovacím zákonem

ODRAZIVOST = 1 - EMSIVITA
27. Fyzikální souvislosti

Stanovení povrchové teploty
●
Termokamera teplotu neměří přímo, ale stanovuje z naměřených
a zadaných údajů. To vyplývá z rovnice termografie.
●
Pro stanovení povrchové teploty je třeba znát (5 parametrů)
– emisivitu [-] (rozumí se emisivita měřeného povrchu),
– odraženou zdánlivou teplotu [°C] (jedná se o tepelné záření, které se
odráží z měřeného povrchu),
– atmosférickou teplotu [°C],
– relativní atmosférickou vlhkost [%] a
– vzdálenost mezi měřicím přístrojem a povrchem měřeného objektu [m].
28. Fyzikální souvislosti
bezdotykového měření teploty www.eko-drony.cz
●
Parametry měření musí
umožňovat zadat každý
přístroj pro bezdotykové
měření teploty.
●
Hlavními parametry jsou
emisivita a odražená
zdánlivá teplota. Jejich
stanovení a zadání do
přístroje je nezbytné.
Zdroj [2]
31. Fyzikální souvislosti
bezdotykového měření teploty www.eko-drony.cz
Odražená zdánlivá teplota
●
Odražená zdánlivá teplota charakterizuje (kvantifikuje) tepelné záření,
které se od povrchu měřeného objektu odráží.
●
Pro těleso s nepropustným povrchem je odrazivost ρ povrchu rovna ρ = 1−
ε, kde ε je emisivita povrchu (všechny veličiny bychom samozřejmě měli
uvážit jako funkce vlnové délky, teploty atd.).
●
Čím menší je emisivita povrchu, tím větší bude vliv odražené zdánlivé
teploty, což je vždy nepříjemné s ohledem na výslednou přesnost měření.
V praxi je proto obvykle méně obtížné měřit povrchy s vysokou emisivitou,
a proto se také snažíme volit takový spektrální rozsah termokamery, aby v
něm byla emisivita měřeného povrchu, pokud je to možné, co největší.

bezdotykového měření teploty www.eko-drony.cz
Kvalitativní x kvantitativní
●
Kvantitativní měření
– Potřebuji znát povrchovou teplotu, nastavuji
parametry měření (alespoň emisivitu a odraženou
zdánlivou teplotu)
●

povrchu

Senzory v infračerveném spektru
●
V závislosti na snímané části elektromagnetického spektra musí
být uzpůsoben také senzor termokamery. Detektory jsou součástí
použitelných senzorových systémů. Senzorové systémy zahrnují
optiku, detektory a elektroniku pro vytvoření obrazu.
●
Základní dělení detektorů z hlediska principu funkce je na dva typy,
tj. na tzv. tepelné detektory a fotonové detektory.
●
Z hlediska spektrálního pásma, v němž je detektor schopen
zaznamenávat infračervené záření pak detektory samozřejmě
dělíme na SWIR detektory, NIR detektory atd.
38. Fyzikální souvislosti
bezdotykového měření teploty www.eko-drony.cz
Detektory pro pásmo SWIR
●
SWIR neboli krátkovlnné infračervené detektory nabízejí jedinečné
zobrazovací možnosti. Detektory SWIR jsou vždy fotonové detektory. Na
rozdíl od zobrazování LWIR nebo MWIR, zobrazování SWIR používá
nejčastěji odražené záření (nikoli tepelné).
●
V tomto ohledu je tedy princip podobný klasickým fotoaparátům, které také
zaznamenávají odražené záření (v jejich případě denní světlo).
●
V závislosti na složení materiálu (chemická struktura) jsou tyto senzory
citlivé v různých vlnových délkách a mohou vyžadovat chlazení k dosažení
žádaného poměru signál/šum. Dle typu použitého detektoru lze vyrobit
velmi odlišné přístroje
39. Fyzikální souvislosti
bezdotykového měření teploty www.eko-drony.cz
Detektory pro MWIR
●
MWIR detekce probíhá přes chlazený fotodetektor,
podobně jako u detektorů SWIR. Pro detekci ve
vlnových délkách MWIR (3 až 6 μm) se používá
HgCdTe polovodičový materiál, InSb (antimonid
india) nebo T2SL (typ 2 SuperLattice).
●
Typický detektor MWIR musí být chlazen na 77 K.

LWIR.
43. Fyzikální souvislosti
bezdotykového měření teploty www.eko-drony.cz
Mikrobolometr – sensor pro LWIR
●
Bolometr je zařízení, jež mění svůj elektrický odpor v závislosti na své teplotě. Ta pak
ve vhodné konfiguraci závisí na množství absorbovaného dopadajícího infračerveného
záření. Množství dopadajícího záření může být tedy určeno ze změn odporu bolometru.
●
Mikrobolometr, respektive mikrobolometrické pole, tvoří matice miniaturních
bolometrických detektorů, které jsou citlivé na infračervené záření v širokém spektru
vlnových délek, především s vlnovou délkou 7 až 14 μm. Pokud infračervená energie
dopadne na jediný element, zvýší svou teplotu a změní elektrický odpor celého
mikrobolometru. Tato změna odporu je měřena a poté je zpracována na teplotní
hodnoty, které lze zobrazit do tzv. Termogramu.
●
99,9% senzorů v termografii jsou právě mikrobolometry. Tedy v praxi se nejčastěji
používají LWIR termokamery.
