The most effective treatment for cataracts is to remove the cloudy crystalline natural lens and implant an intraocular (IOL) in its place. These refractive provide same focusing as do lens. Two IOLs are designed analyzed this paper—these IOL made of (PMMA, Acrylic). quality retinal image compared with healthy eye, which based on (Liou-Brennan) eye model) LBEM). Polychromatic Point Spread Functi...

Many software evolution and maintenance problems can be addressed through techniques of program transformation. To facilitate development of language tools assisting software evolution and maintenance, we created a Domain-Specific Language (DSL), named SPOT (Specifying PrOgram Transformation), which can be used to raise the abstraction level of code modification. The design goal is to automate ...

Memory system congestion due to serialization of hot spot accesses can adversely affect the performance of interprocess coordination algorithms. Hardware and software techniques have been proposed to reduce this congestion and thereby provide superior system performance. The combining networks of Gottlieb et al. automatically parallelize concurrent hot spot memory accesses, improving the perfor...

Software frameworks typically constitute a semi-finished software architecture for a complex application domain that can be adapted to the needs and requirements of a concrete application in the domain. Since the introduction of objectoriented frameworks in the late eighties, the development of software frameworks is still costly and difficult to handle. To reduce development risk, process mode...

This paper describes a threefold method of testing the performance of an array-based ultrasonic tool for nondestructive testing of spot welds. The tool is described in its capabilities, use, and advantages over existing counterparts. Performance testing for and the results from carrying out the testing are described. The three performance testing methods include 1) the use of calibrated samples...

Current virtualization technologies enable hosting of a large number of Virtual Machines (VMs) on a common physical host. The hypervisor interconnects these VMs via Virtual Networks (VNs). These VNs underlie the same security requirements as physical networks. Network elements such as stateful firewalls contribute in enforcing this security. With the advent of stateful firewalls on the hypervis...

Spot detection is an essential step in 2-DE gel image analysis. The results of protein spot detection may substantially influence subsequent stages of analysis. This study presents a novel method for spot detection with the addition of confidence evaluation for each detected spot. The confidence of a spot provides useful hints for subsequent processing, such as landmark selection, spot quantifi...

We studied light curves of GJ 1243, YZ CMi, and V374 Peg, observed by TESS for the presence stellar spots flares. One main goals was to model spotted stars estimate number along with their parameters using our original BASSMAN software. The modeled were subtracted from observations increase efficiency flare detection. Flares detected automatically new dedicated software WARPFINDER. estimated tw...

The aim of the paper is to discuss the use of knowledge models to formulate general applications. First, the paper presents the recent evolution of the software field where increasing attention is paid to conceptual modeling. Then, the current state of knowledge modeling techniques is described where increased reliability is available through the modern knowledge acquisition techniques and supp...
