we report a rare case of congenital foregut cysts (esophageal bronchogenic cyst) in a young woman with history of long term dysphagia. she presented with dysphagia and upper gastrointestinal endoscopy showed bulge submucosal lesion in the distal of the esophagus. endoscopic ultrasound showed a 3×3 cm cystic lesion suggestive for esophageal duplication or bronchogenic cyst. computed tomography o...

Indexing techniques usually are used in modelbased object recognition and ray tracing algorithms. In this paper we present a new method for estimating the threedimensional position of a subject (resp. object) in a circumscribed space based on an indexing method. We construct two and three-dimensional indices of a space, which are used to estimate the three-dimensional position by an interpolati...

This paper proposes a new framework to interpret a two-dimensional line drawing that represents a threedimensional object. The framework synthesizes three algorithms namely thinning algorithms, chain code algorithm based on Freeman Chain Code (FCC), and a new corner detection algorithms that accept chain code series as its input. Linear system of two image regularities namely spatial structure ...

In this paper we introduce a new Packing problem, the Three-Dimensional Knapsack Problem with Balancing Constraints (3BKP), the extension of the ThreeDimensional Knapsack Problem (3KP) where additional constraints related to the packing center of mass are given. The 3BKP consists in orthogonally packing a subset of threedimensional weighted items into a knapsack in order to maximize the total p...

Drying is one of the widely used methods of food preservation and it is a sensitive food processing operation due to undesirable changes in the quality of dried product. In this study the effect of osmotic dyhedration and ultrasound pretreatment prior to convective drying on quality properties of apple slices was investigated. Apple slices were pretreated by osmotic dehydration in two concentra...

Background: The induction of bystander effect via ionizing radiation has been well proven. However, few studies have investigated the bystander effect following non-ionizing radiation, such as ultrasound waves. Here, the bystander effect after different sonication times on human melanoma cell line (A375), is evaluated by assessing cell viability and apoptosis. Materials and Methods: The cells w...

It is widely accepted that textureless su$aces cannot be recovered using passive sensing techniques. The problem is approached by viewing image formation as a fully threedimensional mapping. It is shown that the lens encodes structural information of the scene within a compact threedimensional space behind it. After analyzing the information content of this space and by using its properties we ...
