Robust methods for hand gesture spotting and recognition using hidden markov models and conditional random fields
This paper proposes an automatic method that handles hand gesture spotting and recognition simultaneously. To spot meaningful gestures of numbers (0-9) accurately, a stochastic method for designing a non-gesture model with Hidden Markov Models (HMMs) versus Conditional Random Fields (CRFs) is proposed without training data. The non-gesture model provides a confidence measure that is used as an adaptive threshold to ... إقراء المزيد

Repellent, Antifeedent and Toxic Effects of Certain Plant Extracts on Cotton Leafworm, Spodoptera littoralis Boisd.

Repellent, Antifeedent and Toxic Effects of Certain Plant Extracts on Cotton Leafworm, Spodoptera littoralis Boisd.
Two plants, i.e. Anthemis melanopodia and Artemesia monosperma were tested against the 4th instars larvae of Spodoptera littoralis (Boisd.) under laboratory conditions. Four crude extracts (Hexane, Chloroform, Ethyl acetate and Ethanol) from each of the two plants used were evaluated by two different technique, i.e. residual films and dipping. Results indicated different percentage of mortality in larval depending on the ... إقراء المزيد

Quantitative quality measure for photorealistic three dimensional models
The demand for virtual photorealistic models has been recently increased especially in the field of documenting large archaeological sites. These models are commonly assessed qualitatively as no quantitative measure tool is available. In this work, a new approach is presented for a quantitative measure of models texture similarity. Deciding for the reference texture is crucial. Metrics that have been used ... إقراء المزيد

Chapter Title: Biological and Ecological Studies on Land Snails and Their Control. (Accepted for publication in book "Integrated Pest Management and Pest Control"
Mollusca are the second largest phylum of the animal kingdom, forming a major part of the 10 world fauna. The Gastropoda is the only class of molluscs which have successfully invaded 11 land. They are one of the most diverse groups of animals, both in shape and habit. Among 12 gastropods, land snails (subclass: Pulmonata) are one of the most ... إقراء المزيد

Safety and efficacy of laparoscopic versus open surgery in management of common bile duct stones. Experience at Sohag university hospital.
ABSTRACT Background: Management of common bile duct (CBD) stones includes removal of the gallbladder and clearance of the ductal system which can be achieved through different approaches; endoscopic, laparoscopic or surgical. Objective of this study is to assess the safety, efficacy, technical feasibility and surgical outcomes of laparoscopic common bile duct exploration (LCBDE) versus open surgery in the treatment of ... إقراء المزيد

Effect Of Sand Compaction Piles on the Behavior of Expansive Soil Mohammed M. A. Hussei
One of the most common mitigation heave methods for foundation on expansive clay soil is the full or the partial shallow removal of expansive clay soil and replacement with non-expansive soil, usually used sand cushion (SC). Foundation engineers often suggest some arbitrary thickness for sand cushion without considering the depth of the active zone, which is the zone within which ... إقراء المزيد

A Coupled Random Fixed Point Result With Application in Polish Spaces
In this paper, we present a new concept of random contraction and prove a coupled random fixed point theorem under this condition which generalizes stochastic Banach contraction principle. Finally, we apply our contraction to obtain a solution of random nonlinear integral equations and we present a numerical example. إقراء المزيد
