A technique whereby a deformed fossil is restored to its original shape is termed retrodeformation. This paper develops four such techniques designed to encompass a broad range of fossil types. The retrodeformation techniques are tested using fossil forms developed by a three dimensional graphics application programming interface, PHIGS and PHIGS PLUS.

Computer performance evaluation is a key technology for research in computer architecture. The continuous growth in complexity of computer systems is making this task increasingly complex. In general, the problem of developing effective performance evaluation techniques can be stated as finding the best trade-off between accuracy and speed. This optimal trade-off is dependent on the particular ...

Human pose estimation (HPE) is a procedure for determining the structure of body and it considered challenging issue in computer vision (CV) communities. HPE finds its applications several fields namely activity recognition human-computer interface. Despite benefits HPE, still process due to variations visual appearances, lighting, occlusions, dimensionality, etc. To resolve these issues, this ...

sperm is produced by the testis and mature in the epididymis. for having a successful conception, the fertilizing sperm should have functional competent membranes, intact acrosome, functional mitochondria and an intact haploid genome. the effects of genetic and environmental factors result in sperm vulnerability to damage in the process of spermatogenesis and maturation. in recent years, the fe...

Faults in computer networks may result in millions of dollars in cost. Faults in a network need to be localized and repaired to keep the health of the network. Fault management systems are used to keep today’s complex networks running without significant cost, either by using active techniques or passive techniques. In this paper, we propose a novel approach based on imperialist competitive alg...

Team-based learning is an active learning instructional strategy used in the traditional face-to-face classroom. Web-based computer-mediated communication (CMC) tools complement the face-toface classroom and enable active learning between face-to-face class times. This article presents the results from pilot assessments of computer-supported team-based learning. The authors utilized pedagogical...

Enaminones are those structures made up three various functional groups including carbonyl, alkeneand amine groups which arelocated along with each other in a conjugate fashion. These compoundsare of much attention due to special characteristics and numerous applications. In the paper, sixvarious enaminone structures were theoretically optimized and after concluding, were compared withequivalen...

Introduction Breast cancer is one of the most life-threatening conditions among women. Early detection of this disease is the only way to reduce the associated mortality rate. Mammography is a standard method for the early detection of breast cancer. Today, considering the importance of breast cancer detection, computer-aided detection techniques have been employed to increase the quality of ma...
