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%).

4. NP-Complete Nedir?
● NP, belirsiz Turing Makinesi ile çok terimli (polinomsal) zamanda çözülebilen karar problemlerini içeren
karmaşıklık sınıfıdır.
● Bu sınıftaki problemler belirli Turing Makinesi ile çok terimli zamanda doğrulanabilirler ve bu şekilde
doğrulanabilen her problem NP sınıfındadır. Bu nedenle NP, (belirli Turing Makinesi ile) çok terimli zamanda
doğrulanabilen problemlerin sınıfı olarak da tanımlanabilir.
● Belirli Turing makinesi aynı zamanda belirsiz Turing makinesi olduğundan, P sınıfındaki bütün problemler aynı
zamanda NP'dedir.
● NP-Tam (NP-complete), hem NP olup hem NP-Zor olan problemlerin sınıfıdır. Dolayısıyla bu sınıftaki problemler
NP sınıfının en zor problemleridir.
● Yukarıdaki tanımdan yola çıkarak, herhangi biri çok terimli zamanda çözülebilirse, bütün hepsi çok terimli
zamanda çözülebilir.
6. Bileşenleri
1- Yukarıdaki yapı figüründeki gibi iç içe geçmiş zarlar ile ayrılmış bölgelerde bir
dizi olarak.
2- Her bölgede, bir alt algoritma / işlemi çözerek optimizasyon sorununu
gidermek ya da geçici olarak çözmek.
3- Komşu bölgelerin aralarında ulaşım çözüm sistemleri.
7. Başlangıç Kuralları
1- Yukarıdaki yapı figüründeki gibi iç içe geçmiş zarlar ile ayrılmış bölgelerde bir
dizidir.
2- Her bölgede, bir alt algoritma / işlemi çözerek optimizasyon sorununu giderir
ya da geçici olarak çözer.
3- Komşu bölgelerin aralarında ulaşım çözüm sistemleri uygulanır (örn. tabu
search).
En iyi çözüm en içteki bölgededir.
8. Membrane Algoritmasının Ayrıntıları
m membrane sayısı olsun ve bölge 0 içteki bölge ve m-1 dıştaki bölge olmak
üzere sıralayalım.n düğümleri ile bir örnek olarak İki boyutlu uzayda noktalara
karşılık gelen gerçek sayılar (xi
,yi
) (i=0.1,……,n-1) çiftini içermektedir. İki
düğüm arasındaki mesafe
v i
= (xi
, yi
) ve vj
= (xj
,yj
) geometrik mesafesi d(vi
, vj
) = (xi - xy
)2+(yi - yj)2dir.
Bu çözüm listesi (v0
, v1
, …., vn-1
) olur. v = (v0
,v1
,.....,vn-1
) ile gösterilen değer
kümesi W(v) ile belirtilmiştir;
9.
10. Gösterilen iki çözüm olan u ve v için, v u dan daha iyi ise W(v)<W(u) olur. Olası
tüm çözümlerde minimum değeri olan çözüm örneğinin kesin çözüm olduğu
söylenir. Tam çözüme yakın değeri olan çözüm yaklaşık değer olarak
adlandırılır. Algoritmanın 0 bölgesinde belirsiz, 1 den m-1 e kadar olan
bölgelerde ise iki çözüm vardır. 0 bölgesinde tabu arama algoritması gibi bir alt
algoritma kullandık. Tabu algoritması çözümün içindeki iki düğüm arasında
belirsiz çözüme yakın bir çözüm arar. Arama sonuçlarında iki kez aynı
çözümün görünmesini engellemek için düğümleri listede tutar. Tabu listesindeki
düğümler tekrar değiştirilmez. Eğer aşağıdaki üç durumdan biri oluşursa tabu
arama algoritması belirsiz çözümü sıfırlar ve listeyi sıfırlar:
11. 1. Komşu çözümün değeri belirsiz çözümden daha az ise, Komşu çözüm
belirsiz bir çözüm olur.
2. En iyi çözümün değeri Bölge 1 dedir. Bu geçici çözümünkinden daha
düşüktür.
En iyi çözüm Bölge 1 de yeni geçici çözümle oluşur.
3. Komşu araması önceden belirlenmiş turların aşılmasıdır(n/5 durumunda).
Geçici çözüm kalır. Sadece tabu listesi boşaltılır.
12. Durum 3 te hiçbir gelişme oluşmaz. Fakat tabu aramada diğer komşuları da
aranarak denenir. Çünkü aranamayan komşularda vardır.
Geçici çözümler Bölge 1 ile m-1 arasındadır(Her bölgede iki çözüm vardır.).
Bunlar aşağıda özetlenen bir alt algoritma tarafından geliştirilmiştir.
13. 1. Eğer iki çözüm de aynı sonuca sahipse, çözümün bir parçası iptal edilir.
(Burada ihtimal seçilir.)
2. İki sonucu yeniden işleme sokar ve iki yeni sonuç üretir.
3.İki yeni sonuca nokta değişimi uygulanır. i-th durumunda, değişimde i/m den
daha düşük bir ihtimal oluşur.
14. Belli ki alt algoritmalar yukarıda genetik algoritmayı andırarak tanımlanıyor.
Fakat alt algoritmalar her zaman genetik algoritmanın rastgele işleme sokmak
için seçtiği durumlarda iki sonucu işleme tabi tutar. Eğer iki çözümde bir
durumda aynıysa işlem yenilendiğinde yeni sonuç üretilmez. İlk adım bu
durumu önler ve geri çevirme işleminde kullanılan yeni bir çözüm tanımlar.
15. Genel Bakış
1. TSPnin örneği verilmiştir.
2. Bütün Durum 1 ile m-1 arasındaki Durum 0 ve yeni geçici çözümler için gelişigüzel bir
geçici çözüm oluşturulur.
3. d zamanı kadar 3.1 ile 3.3 arasında tekrar ederler.(d değeri bir parametre olarak
verilmiştir.)
3.1 Alt algoritmayı kullanan bütün durumlar aynı anda geçici çözümler oluştururlar.
3.2 Bütün durumlar için i(1 <= i <= m-2), durum(son durum ve yenilenen durum) ile
durum i-1 arasında ve en kötü çözüm de durum i+1 iken durumların en iyi durumunu
gönderir.
3.3 Bütün durum 1 ile m-1 arasındaki çözümleri temizlerler.
4. Geçici çözüm çıktılarında Durum 0 algoritmanın çıktısıdır.

Kötü 786 457 450 444 445
17. Membrane algoritması 3. adımı 40000 kez kadar tekrar eder. Membrane
algoritmasının denenme sayısı 10dur. Membrane 2,10,30, ve 50 sırasıyla
2,10,30 ve 50 durumları için algoritmaları geçerli olur.

Kötü 49667 24862 23940 24531 22564
19. iyileştirilmiş Membrane
Bileşik Membrane algoritması iki aşamadan oluşur(Şekil 3). İlk aşaması bir dizi
membrane algoritmasını rastgele oluşturulan ilk sonuçlarından iyi sonuçlar
oluşturur. Bu iyi çözümler sonuçlarla sırasıyla ikinci adımdaki ilk sonuçları
üretir. Sonunda en iyi sonuç elde edilmiş olur.
20.
21. Takip eden parametreleri ile birleşik membrane algoritması incelendiğinde:
● İlk adımda membrane algoritmasının dizisi 100dür.
● Bütün membrane algoritmaları 50 membraneden oluşur.
● Eğer en iyi sonucu 500 iterasyonda yakalayamazsa her bir membrane algoritması ilk adımda
sonlandırılır.
● Eğer en iyi sonucu 5000 iterasyonda yakalayamazsa her bir membrane algoritması ikinci adımda
sonlandırılır.
Birleşik Membrane algoritmalarında bilgisayar deneylerinin sonuçlarını Tablo 3 te gördük.
Fark ettik ki birleşik membrane algoritmalarında her zaman neredeyse birbirine çok ykın sonuçlar üretiliyor.
Bir süreçte birleşik membrane algoritmasının zamanını tek bir membrane algoritmasından çok daha uzundur.
Çünkü membrane algoritmasında birinci adım bütün işlemlerden bağımsızdır.

● Optimizasyon problemlerinin çözümü için membrane algoritmasını yeni bir
algoritmayı uyarlarken ve sunarken kullandık. Bilgisayar deneylerinin TSP*
için membrane algoritmasının en iyi çözüm yaklaşımı olduğunu gördük.
● Membrane algoritmasının yaklaşımı hızlıdır.
● Gelişmiş membrane algoritmasının, birleşik membrane algoritmasından
TSP* için genelde neredeyse tam sonuç çözümdür.
