How to put chapter number after chapter title in thesis documentclass?

Why chapter title in thesis documentclass positioned below chapter number? I mean I need to place both of chapter title and chapter number in one line.

• Something seems to be amiss with your chapter header in terms of the spacing before the number. Did you change something already in that regard? Are you using a special \documentclass? Could you provide a minimal working example (MWE) that replicates the current layout? – Werner Dec 24 '13 at 8:28
• Can you give us an MWE, so that we can see, what packages you are using and what attempts you have tried? one nice way to format the titles of sections, chapters and so on is the titlesec package. – Ronny Dec 24 '13 at 8:30

Here's a solution, using the titlesec package with the explicit option:

\documentclass[11pt, twoside]{report}% http://ctan.org/pkg/amsproc

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[explicit]{titlesec}%
\usepackage{xcolor}
