Bariatric or weight loss surgery is the reduction of the size of
the stomach with a gastric band or through removal of a portion of
the stomach, or by resecting and re-routing the small intestine to
a small stomach pouch. Metabolic surgery involves weight loss
treatments and procedures to treat metabolic diseases, especially,
Type 2 diabetes. This book is a guide to techniques in bariatric
and metabolic surgery. Divided into three sections, the text begins
with an explanation of the history of bariatric surgery. The
following section presents 25 clinical cases detailing necessary
operative procedures for different disorders, and the final section
discusses surgical techniques including sleeve gastrectomy, gastric
bypass, and stapling technology. Based on the authors' own
experiences, this quick reference guide is further enhanced by more
than 200 surgical images, diagrams and tables. Key points Quick
reference guide to procedures in bariatric and metabolic surgery
Features 25 clinical cases for use of bariatric surgery Describes
different surgical techniques Includes more than 200 surgical
images, diagrams and tables

Master's Thesis from the year 2013 in the subject Computer Science
- Miscellaneous, grade: 1, course: ME computer science, language:
English, abstract: This paper investigates how demand-side factors
contribute to the Internet's "Long Tail" phenomenon. It first
models how a reduction in search costs will affect the
concentration in product sales. Then, by analyzing data collected
from a multi-channel retailing company, it provides empirical
evidence that the Internet channel exhibits a significantly less
concentrated sales distribution, when compared with traditional
channels. The difference in the sales distribution is highly
significant, even after controlling for consumer differences.
Furthermore, the effect is particularly strong for individuals with
more prior experience using the Internet channel. We find evidence
that Internet purchases made by consumers with prior Internet
experience are more skewed toward obscure products, compared with
consumers who have no such experience. We observe the opposite
outcome when comparing purchases by the same consumers through the
catalog channel. If the relationships we uncover persist, the
underlying trends in technology and search costs portend an ongoing
shift in the distribution of product sales. Singular Value
Decomposition (SVD), together with the Expectation-Maximization
(EM) procedure, can be used to find a low-dimension model that
maximizes the log likelihood of observed ratings in recommendation
systems. However, the computational cost of this approach is a
major concern, since each iteration of the EM algorithm requires a
new SVD computation. We present a novel algorithm that incorporates
SVD approximation into the EM procedure to reduce the overall
computational cost while maintaining accurate predictions.
Furthermore, we propose a new framework for collaborating filtering
in distributed recommendation systems that allows users to maintain
their own rating profiles for privacy. We conduct offline and
online t
In the design of sculpted objects such as the exterior of the car
body, the design engineer is interested to capture the shape of the
sculpted clay or wooden model and create a computer aided design
(CAD) model for product development. This technology is also known
as reverse engineering of shape. Constructing a CAD model from
point cloud data is an inverse problem that is generally ill posed
because the information one has does not uniquely determine the
solution. New methods based on soft computing techniques such as
neural networks, genetic algorithms and traditional analytical
techniques for free-form surface recognition, parameterization for
surface modeling and contour model recognition for rapid
prototyping from point cloud data are presented in this book. The
treatment of the subject should especially be useful to
academicians and professionals who work in the areas of CAD, 3D
data acquisition technologies and rapid product development. This
book may also be of general interest to anyone who wants to
appreciate the computing techniques that go behind the point cloud
processing and surfacing software.
Machines and mechanisms form the backbone of industries, implements
in agriculture, space exploration, and various appliances used in
our daily lives. This title contains new developments at the core
of the science of machines and mechanisms, as well as their
applications in various walks of life. The contents represent
contributions made by about two hundred researchers, practising
engineers, and educators working in the fields of analysis and
synthesis of mechanisms, robotics, compliant mechanisms, dynamics
and control, design of machines for the industries, rural and
agricultural sectors etc. in the 15th National Conference on
Machines and Mechanisms (NaCoMM 2011). The variety of topics and
the diversity of view-points should make the title significantly
interesting to the beginner and expert alike in the general field
of design and analysis of machines and mechanisms.
