Dror Ceder is Co-CEO and Co- founder of Wibiya and completely addicted to all things “Wibiya”.
During non-Wibiya hours Dror enjoys playing squash, trekking mountain and most of all clearing his mind on the cliffs of Arsuf, overlooking the Mediterranean Sea. His two favorite things besides his wife Valerie are mountain peaks and laughter. He is desperately trying to overcome is his first-thing-in-the-morning iPhone addiction, checking emails and latest sports news. He loves listening to music and watching movies and his favorite quote is by George Bernard Shaw:
“You see things; and you say, ‘Why?’ But I dream things that never were; and I say, “Why not?”

Daniel Tal is Co-CEO and Co- founder of Wibiya.
After serving 5 years as a Captain in the Israeli navy, Daniel returned to shore and connected to the Internet. After finding Dror and Avi, Daniel realized the potential a small skillful team has in making its mark on the web. Together they embarked on a journey to build and develop Wibiya.
Daniel spends his vacations windsurfing and trekking through exotic spots around the world with his spouse Michal. To clear his mind, he swims 3 times a week and listens to audio books during his 125 miles drive from home to the office and back. Daniel lives in a small Moshav in the South of Israel, where the air is cleaner and his two dogs can run free.

>Deconvolusi

Deconvolusi umumnya dilakukan sebelum stacking akan tetapi dapat juga diterapkan setelah stacking.
Selain meningkatkan resolusi vertikal, deconvolusi dapat mengurangi efek ‘ringing’ atau multiple yang mengganggu interpretasi data seismik.
Deconvolusi dilakukan dengan melakukan konvolusi antara data seismik dengan sebuah filter yang dikenal dengan Wiener Filter .
Filter Wiener diperoleh melalui permasaan matriks berikut:
a adalah hasil autokorelasi wavelet input (wavelet input diperoleh dengan mengekstrak dari data seismik), b Filter Wiener dan c adalah kros korelasi antara wavelet input dengan output yang dikehendaki.
Output yang dikehendaki terbagi menjadi beberapa jenis [Yilmaz, 1987]:
- Zero lag spike (spiking deconvolution)
- Spike pada lag tertentu.
- Time advanced form of input series (predictive deconvolution)
- Zero phase wavelet.
- Wavelet dengan bentuk tertentu (Wiener Shaping Filters)
Zero lag spike memiliki bentuk [1 , 0, 0, 0, …, 0] yakni amplitudo bukan nol terletak para urutan pertama. Jika Output yang dikehendaki memiliki bentuk [0 , 0, 1, 0, …, 0] maka disebut spike pada lag 2 (amplitudo bukan nol terletak para urutan ketiga) dan seterusnya.
Dalam bentuk matrix, Persamaan Filter Wiener dituliskan sbb:
dimana n adalah jumlah elemen.
Matriks a diatas merupakan matriks dengan bentuk spesial yakni matriks Toeplitz, dimana solusi persamaan diatas secara efisien dapat dipecahkan dengan solusi Levinson. Dengan demikian operasi Deconvolusi jenis ini seringkali dikenal dengan Metoda Wiener-Levinson.
Untuk memberikan kestabilan dalan komputasi numerik diperkenalkan sebuah Prewhitening (e) yakni dengan memberikan pembobotan dengan rentang 0 s.d 1 pada zero lag matriks a (sehingga elemen a0 matrix diatas menjadi a0(1+e).
